I'm sure you could go down to PM and say exactly what you've said here and get more recommendations than you can handle.

There are lots and lots of cool, challenging and beautiful puzzles out there - and you live near a warehouse full of them!

I assume there's a retail store, too? and the guys who do their videos must work there as well as Allan Stein who founded the company - I'll bet they all love to recommend stuff.

That said, browsing the site is fun once you find your way around and can avoid the things you don't like

Here's my standard "how to get started" rap (a little old, so some items might be unavailable):

I'd say you probably want to check out several different categories of puzzle:

  • Disentanglement - This includes the wire puzzles, but also the various metal, wood and rope and wire and string varieties. I'd look at a couple of the harder wire puzzles as well as one or two metal and string or wood and rope puzzles. If you're new to these, ThinkFun put out a "Houdini - Master of Escape" set that's actually like a step-by-step course in disentanglements
  • Packing/Assembly - Usually wood or plastic, these range from the ever-popular Soma Cube and other "make this shape from these pieces" puzzles to really complex packing problems - often in the form of "put these pieces into the box so the lid will close" or "fit these pieces in the frame" There are also some interesting hybrids like the 4L puzzle from Cubic Dissection or the LUV puzzle from Rombol (a Stewart Coffin design that's pretty tricky)
  • Interlocking Burrs - My favorite category. Includes the traditional 6-piece Burr and variations by the thousands. I highly recommend the work of Stephan Chomine and Osanori Yamamoto in this area, but there are lots of great designers. Baumegger, Demirhan, Eyckmans, etc. Do a search for Pelikan (a manufacturer) on various puzzle sites. This is a pretty deep category with lots to explore - one subgenre is the TIC puzzle (Turning Interlocking Cube) which BurrTools won't solve (look for work by Ken Irvine, Jeff Namkung or Jos Bergmans). See more below
  • Puzzle Boxes - Lots of fairly shoddy ones around, but some very nice things out of Japan (check the Karakuri Creation Group). The good ones tend to be expensive.
  • Twisty - Rubik's Cube and its descendants - not my thing, but there are a million variations out there.
  • Sequential Movement - sliding block puzzles and various sequencing puzzles (sometimes an overlap with the Twisty or Disentanglement categories). A great, cheap example is Rush Hour from ThinkFun that, like the Houdini set mentioned earlier is like a graded course in sliding block puzzles

    Anyway, I'd say try a couple of disentanglement things (both wire and wood), a packing puzzle or two and a few interlocking burrs (I recommend trying a relatively traditional one and a couple of the fancier ones from Pelikan or Cubic Dissection). See what sort of things appeal to you and follow on from there.

    Do check out the links in the sidebar, too. Allard's Blog and PuzzleMad are great, Rob's Puzzle Page is vast and you can learn a lot just by browsing PuzzleMaster and some of the other shops.

    Here is a list of wooden burr-type puzzles under $30 that I have played with and enjoyed - I made this awhile ago so thy may not all still be available, but this should get you started

    **Open Box Packing aka Deadly Romance - a really nice caged burr

    Cross Cage by Tom Jolly - a burr? 3D maze? Pretty cool

    Four Caged - a really tough little caged burr

    Epsilon - a knockoff of Vertex Burr #1 , originally designed by Yavuz Demirhan in 2012 - great puzzle

    Shape Shifter - very tough assembly puzzle - soma cube on steroids

    Sarcophagus - surprisingly challenging. I have a thing for "3 sticks in a box" puzzles like Tribord

    Matchbox aka Oscar's Matchboxes- tricky and a cool idea

    Double Saturn - similar to some of Osanori Yamamoto's classic work, this is tough little Pelikan-style puzzle on the cheap

    Four L - like The Double Saturn above
  • NOT to be confused with the **4L from Cubic Dissection (which is a truly great puzzle,but OOP now)

    Quadstair

    Four In The Box - just above the $30 limit, but it's pretty fun and two puzzles in one

    Feel free to ask questions on the sub about specific puzzles or categories

    Puzzlers are a pretty supportive community - welcome!

That's a tough one to answer really, but here are a few thoughts on the subject.

If you are looking for the really basic stuff, as in you still need to learn ohms law and how to read a circuit diagram you can start out with the absolute basics;

  • 200 in one kit: I started out with this one in 1984 and it's still around. You can also do a search for "electronic bricks", "snap circuits" or some such. It's considered more of a toy than anything else, but it will quickly get you up to speed at least.

  • There is a 2 part lab made to go with a book by Forrest Mims at Radio Shack... Can't find it online, but it's a pretty good kit that goes with a good reference. It's one of the few things Radio Shack offers at a sort of reasonable price.

  • Check out any number of sites for "Basic Electronics Kit". A lot of kit places will separate their kids by skill level. This won't give you an in depth understanding of all things electronic, but it will give you the "learn by doing" experience. You'll build things like larson scanners, and refrigerator alarms, pretty useless, but they are cheap at least.

  • I'm going to add 'any arduino kit' to the list. You won't get ohms law or reading circuit diagrams as part of the lesson plan, but most of these kits will have lessons on how not to fry your arduino and you can pick up the basics by induction

    Now, if you already have the circuit reading and ohms law down and you just want to know where to go from there, you've got a lot more choices.

  • Assemble your own kit: Once a person finishes with the above suggestions, they realize that it all would have been cheaper had they just done this at the beginning... Unfortunately, before you go through the basics you probably have no idea what to get for your self assembled kit. Electronix Express has two parts kits and a tool kit. I wouldn't call them the best, but they do have a wide selection of parts at a decent price.

  • Arduino kit. Yes, I mentioned this already, but it's also a good step when "moving up" and learning microcontroller basics. There are better microcontroller boards out there, but arduino is like Ubuntu Linux; lots of community support.

  • Advanced kits. Yes, I skipped intermediate kits. You can still look at those, but really, the difference between basic, intermediate, and advanced kits to me seems to have more to do with confidence than anything else. More parts, more complex diagrams and instructions. These kits will take you longer, but they are no more difficult than any other. One thing they sometimes offer is customizability which offers a great learning experience. I DO suggest that you find a kit that has some kind of support; a forum on the sellers website, or even user made videos on youtube. The instructions you get may not mention things like using blue-tac to hold buttons in place or have other helpful hints that a community may have for you.

    Well, lot to think about there. Good luck, and don't forget /r/AskElectronics for help.

Dave from EEVblog recommends building power supplies. They're pretty simple, and it doesn't hurt to have a bunch of them. You can find kits, which will teach you how to solder parts onto a PCB, but it's not too hard to design a supply around an LM317 regulator, the data sheet will have the circuit you need right on it. This will also be a good chance to learn the non-electronics skills you'll need; instead of buying a plastic box, make one out of plywood and paint it up.

Once you have a power supply or three, start playing around with simple analog circuits. You should have a breadboard and jumper wires and at least one good multimeter, though the aforementioned EEVblog recommends two, and not cheaping out on them. He did a $50 multimeter shootout , if you don't want to watch an hourlong video this was the winner, but it's worth watching to see why it won. Anyhow, you can find kits and project ideas online, get some random parts and start playing around until you have a good feel for old school analog circuits. Try to make up your own project and build it, even if it's completely useless.

At some point, preferably after you have a good grasp of analog circuits, you're going to have to move up to digital. Arduinos are a good start, they're popular enough that you can't look at a single page of Instructables without tripping over an Arduino project. You're going to have to learn some programming to make it go, but there's a million tutorials online. To make the pinball machine go, you're going to have to learn how to use the Arduino (or something like it) to control analog components, probably while giving them their own external power source. You'll also need to know how to drive a display for the scoreboard, and of course you'll have to program the logic for keeping track of the number of balls left, current score, and what inputs translate to what increase in score. The programming alone is a big undertaking, so if you go forward on this, be prepared to spend years on it.

A good project to do would also be to make a MAME cabinet. It's much simpler on the electronics side, you either hack the buttons and joysticks into a USB keyboard controller, or buy one of these which does the same thing, and then use an old PC and monitor. The hard part is building an arcade cabinet, which is still a lot simpler than building a pinball table. You'd be looking at a couple hundred dollars in parts, but that's not too bad compared to what you want to end up doing.

I have 3 nephews, so I've been through that. Right now I'm struggling with what to get them at 13 and 16.

This probably isn't the "coolest" gift, but it's a good gift and not all that expensive: Money Savvy Piggy Bank.

Snap circuits say they're good for 8 year olds, but you can judge your nephews on that, and I think they may have simpler sets.

Think Geek now has a kid's toys section. Also Edmund Scientific has great educational toys.

If they're into Lego, Kenex are great too.

I find surfing Amazon is really good for finding stuff; put in some toys you know they have and like, and see what other people bought that's similar.

I usually try to get my nephews one gift I think that's good for them, and one gift that they'll just have fun with.

Well, on-camera flash tends to look pretty terrible when it is pointed directly at the subject. (Think deer in headlights) Direction of light matters more than diffusing, but diffusing is useful.

So first, you want to address light direction:

  1. Use a hot shoe mounted flash, but angle it upwards so it bounces off the ceiling and comes at your subject at a more natural/attractive angle. If you ever hear "bounce flash", that is really all it means, pointing somewhere to bounce onto the subject. Note that with the A6000 you can actually use its built-in flash and use your finger to point it upwards to achieve bounce. There are also these nifty little plastic things to do bounce. Found here:
    https://www.amazon.com/dp/B00LEX4RW4/

  2. Use a flash off-camera flash with a hotshoe mounted transmitter. There are a number of options here.

    Once you get the hang of light direction, you can add "modifiers" like diffusers to the front of the flash to soften the light or direct it.

    I would experiment with bounce flash first with the built-in flash. Note that bounce flash becomes ineffective in places with high ceilings like hotel lobbies/atriums.

    Once you are ready to buy a flash, I recommend the Godox TT865S which supports Sony TTL and HSS for about $119. It can mount in the hotshoe for bouncing at much higher power than the built-in flash. It can also be used as a off-camera triggered flash with the Godox X1T-S transmitter. Both of these can be purchased for about $150 total. You can set the power level or flash compensation on the transmitter and put the flash on a stand or hold it out with your hand, or have a friend/assistant hold it to the side of the model, etc.

    Here is a amazon link for the Godox TT685S for $119 and includes a softbox diffuser that optionally covers the front of the flash:
    https://www.amazon.com/Godox-Speedlite-0-1-2-s-Supports-20-200mm/dp/B01DTXB66G

    Here is the transmitter for $46:
    https://www.amazon.com/Godox-Wireless-Trigger-Transmitter-ILCE6000L/dp/B01EHJM8QI/

    Please note that these links are NOT referral links, I am not trying to make any commission, these are just direct amazon links.

    Best of luck!!

My minecraft kid really loves the shirts that feature his youtube heroes, in fact i'm getting him a pat and jen shirt this year, but he also loves the dantdm one from walmart. As Ejalamung suggested, sunglasses are huge and a watch is great. Those are two really good ones.

Nerf shooters go over really big, as well as the toy archery kits.

Have you looked at anything like snap circuits?

Classic games are always good as you are familiar with them and you can re-use components for some. My favorites in no particular order

Games

Hangman
Read a list of words from a file, randomly select one, and play a game of hangman!

War
Model cards and a deck of cards, give the 'AI' half the deck, the player the other half, then keep drawing with user interaction. Doesn't really require AI and is a pretty simple simulation

Tic-Tac-Toe
Self explanitory. Bonus points for functional AI

Rush Hour
See classic rush hour games. Get the player's car to the other end of the traffic jam. Bonus points for a hint system where the next move is given to you.

Sudoku
The classic numbers puzzle. Again, bonus points for a prediction system. bonus points + 1 for a solver (given any soduku puzzle from your favourite puzzle book, it will automatically solve it for you)

Applications

Tip Calculator
Calculate tips. Bonus points for not using any buttons (I.e., the tip is automatically re-calculated when you move a slider / edit a value)

Grocery List
Create a list of grocery items for going to the store. Be able to save out and read back in Grocery Lists. TripleQuadruple bonus points for being able to print.



Edit: I would like to add -> you shouldn't focus on projects for python. Think about what you want to do, then think about the best tool for the job. All of these can be done in python. But you should be focusing on the overall process, not the specific language you are learning if that makes sense. For example, if you learn to do it in Python, you should be able to do it in C# and Java as they have pretty similair (relative) mechanics. Write down a lot of crap before you write a line of code. What objects do I need? How will these objects interact? Am I even going for an OOP model, or can/should this be implemented functionally?

u/ratsta · 3 pointsr/AskElectronics

Way back when dinosaurs roamed the Earth and I was a young fella, I forget how old but probably pre-teen, my parents bought me something like this: http://www.amazon.com/Elenco-200-in-One-Electronic-Project-Lab/dp/B0002AHR04 To make a circuit, you'd just bend back a spring and shove a wire in between the coils. Looking at the "related products" on Amazon, it seems like there are a few competitive products out there too. The kit my parents got me kept me entertained for a very long time. This was possibly enhanced by my father who, being an electrical engineer, would periodically involve me fixing broken appliances, handing me the sledge to help tear down walls during renovations and whatnot.

This kit taught me the basics of flip-flops (which can be used to MAKE NOISE! as well as flash lights), relays etc.

---

My current flight of fancy is the Arduino and that may prove a more useful tool for you because it can all be done with low voltage, a bread board and a bunch of wires and even better, it needs a computer to program it. The Arduino IDE includes a whole bunch of example programs.

The most basic program is "flash" which just literally flashes an LED. Your next step would be to alter the duty cycle of the flashing. Now have it flash two LEDs and have them on different duty cycles.

A Chinese Arudino UNO clone Starter Kit (which in addition to some basic components and a breadboard includes a stepper motor, servo, tilt switches and other cool things) will set you back less than $50. Additional wires (I recommend getting a pack each of M-M, M-F and F-M dupont leads) are cheap as chips and will help you hook up all the other awesome things you can get like the "arduino sensor kit" which contains no less than 37 different kinds of "sensors" including ultrasonic range sensors, joysticks, push buttons, etc.

Armed with those two kids, a bunch of wires and a laptop running the Arduino IDE, there's a whole world of awesome to play with.

Show me pre-teen who wouldn't like an ultrasonic alarm pointed at her door to make a buzzer ring when mum opens the door, and I'll show you a kid who... is too engrossed in a book to notice. (OK, so my analogies aren't always top notch)

u/saiph · 7 pointsr/Feminism

There are lots of great gender neutral toys for all ages! I'm especially fond of building toys, especially for younger kids. Blocks and tinker toys are great (I looooooved mine), and legos (especially those open-ended sets) are good for when they get a little older.

Educational toys are also a good one. A three-year-old isn't gonna realize that a set of Go Fish Alphabet cards will help them learn the alphabet. They think it's just a fun game. Older children can move into board games and puzzle games like Rush Hour.

A lot of arts and craft kits are gender neutral, too. Remember those Klutz books? Sure, they've got Glitter Face Paint While You Do Your Nails and Have a Tea Party kits (which, tbh, I actually don't think are that bad), but they've also got some awesome kits for paper airplanes, origami, learning magic, and learning to sew (a skill that everyone should have).

Also, science toys and kits. Chemistry sets are perfect for older kiddos, and younger ones are happy with dinosaur action figures or solar system plushies.

Finally, books. You can never go wrong with books.

What did you enjoy playing with as a child? Does the giftee have any particular interests (e.g. crafts, music, reading, science)? I'd start with those two questions and go from there.

Expensive STEM stuff -- I've worked with all of them. If I had to get one, I'd probably do Osmo.

Bee bots

Other Manipulatives and Toys:

Reptangles - I found these at Savers and my students are super in to them right now.

Snap Circuits

Ikea Cars (not really stem but fun and high quality)

Mobilos -- can create cars but also so many other things

Marble runs of any style

"Pattern Play" Blocks -- We have these but I don't have the instructions, but kids still end up making fun designs out of them!

BIG Waffle Blocks

Architectural blocks sets -- for example

------

I have a major soft spot for board games (and related) at this age. Here are a few I love.

Animal Upon Animal

The Little Orchard

Count Your Chickens

Snug as a Bug in a Rug

Snail's Pace Race

Rivers, Roads, and Rails

-----

Ultimately, though, your focus should be on having fun! Your 3 year old does not need to be reading and writing or doing basic math. He should be learning to play cooperatively, self regulate, and be independent. I would focus on language skills and his ability to communicate effectively and understand directions. I teach Pre-K (currently 5 year olds about to go into Kindergarten) and I do not care at all whether they can write their names or do simple math.

u/fut- · 5 pointsr/DIY

You can't really skip the theory if you want to work on meaningful, original projects; you probably don't have to read "The Art of Electronics" (1000+ pages!), though. If you have a basic understanding of physics or software engineering, I would shamelessly plug my own short but anatomically correct guide to electronics here.

When it comes to hands-on experience: IMO, single-purpose kits (from Sparkfun and so forth) are probably not that great. They are good to practice soldering and get results quick, but do not teach you much: when you are done, you likely won't be able to recreate that circuit from scratch, or alter it to your liking. Trying to understand - and then building - various projects from All About Circuits, Make blog, or so, might be more worthwhile, as they usually come with a much better and more verbose explanation of how things work, and how the author arrived at that particular design.

Oh, and here's an unorthodox tip: if you are intimidated by breadboards or perfboards, this great set should be a good way to experiment with fairly sophisticated circuits, too. I have it for my kid, but I would not be ashamed starting with it as an adult: unlike their "snap-on" sets, it's not dumbed down at all.

What next? As soon as you are reasonably comfortable with analog electronics, you should try harnessing the power of digital circuits. My recommendation would be to start with understanding 7400 series ICs (well, 74HC), and build a variety devices with it. Heck, a calculator or a rudimentary computer is really not that complicated, and it's extremely satisfying to put them from basic logic components alone!

At that point, moving to AVR ATmega microcontrollers (using avr-gcc or WinAVR) should be a breeze - and will enable you to do complex data processing and output control for your circuits with little or no effort.

A seemingly convenient shortcut is to go with Arduino for digital circuitry instead; the upside is that the platform has a less pronounced learning curve, and a vibrant hobbyist community. The downside is that you end up paying a lot more, and you will soon realize there is no escaping the pesky low-level details if you want to master more advanced devices.

I think much of engineering is like that...it's insane what they expect us to learn in 4 years. I had to take a circuits course, and then my dynamic systems professor happened to be an EE, so most of our crazy-long homework sets and exams involved circuits. Our CAD course was a two-hour class each week with homework that would take everyone hours to complete, but it only counted for 1 credit. All 4 of my chemistry labs were 2 credits each, but they were 9 hours per week in lab, plus all the time it took to study for quizzes and write lab reports. I actually talked to the department chair about that, and he told me that he knew the labs should be at least 4 credits each, but they couldn't make them worth that much or they'd exceed the amount of credits they were allowed to require for graduation. So they left them at 2 credits despite the time and workload being so staggering. It was like that across the board. Hooray for technical majors, right? I guess this explains the high level of depression and dissatisfaction among students majoring in engineering or science.

I hope you're already seeing the light at the end of the tunnel (and might I add it's pretty neat you're the only other BME I've met on here, and you're a girl--yay!).

Also, this conversation reminded me of one of my favorite toys as a kid. XD

  • Fire TV Stick, which is a lower-cost alternative to the awesome Fire TV. (think Apple TV, but actually good)

  • Raspberry Pi which is a tiny fully-functional/fully-featured ARM computer.

  • Arduino, which is an easy-to-use electronics prototyping platform, great if you're interested in learning how to make your own electronics and whatnot. (you might also want this, this, this, this, and this. Should be less than $40 altogether, though you could also probably find like a starter kit that comes with an arduino, book, and components.)

  • Huion drawing tablet, great for if you want to do digital art. I haven't used this model specifically, but I do have the (bigger/more expensive) Huion 610 Pro, which I love.

  • Amazon Prime student was like $40 IIRC, not sure if that has changed though.

  • I can't recommend a better book than this one.
  • Get this resistor kit. Seriously, I bought one of these a year ago and I've never once had to buy more resistors.
  • You're going to need a capacitor set like this one.
  • You're also going to need a breadboard.
  • Make a trip to Maplin and get an assortment pack of LEDs and a few switches. Trust me, this will make your life a tons easier when it comes to making proof of concept or test circuits. And they make circuitry more interactive and fun!
  • Lastly, get a cheap multimeter. You can get one at Maplin or somewhere similar for like <15 pounds.

    Sorry about the links, I'm in the US so the prices will be in USD but that shouldn't be a problem. I really hope you find this hobby as intriguing as I do, I started a year ago making little flashlights and what-not and now I'm making motion detectors and all kinds of cool gadgets. If you'd like some guidance or help, don't think twice about PMing me! Best of luck.

This is a solar powered toy car.

Why am I showing you this? Because it's a toy that is powered by the nuclear fusion of a star 8 light minutes from here. How cool is that?!?

Oh, but I was supposed to tell you something about ME? That's tougher. Technically I'm also powered by nuclear fusion which occurs in the sun's core, but only indirectly. Also that's not a terribly unique characteristic, most people and animals and plants and all life on earth is. (Except for the random stuff living along volcanic vents deep beneath the ocean.)

So let's get more unique. Well I share 98% of my genetic material with a chimpanzee, and 50% of my genetic material with a banana. Shoot... That's unique to humans, but not so much to me personally.

Ok, how bout this? I once found a painting of an ancestor in the Smithsonian museum of American History and not only did he have the best facial hair OF ALL TIME, but he looked strikingly like my father would should my father ever choose to grow THE BEST FACIAL HAIR OF ALL TIME.

Yeah you've pretty much got it. The controller you linked is the newest version of the teensy, and while it will work fine and will be more upgradable, since you are on a budget you could use any of the teensy boards for this. I would probably just a teensy++ or 2.0. As far as upgradability goes, it depends on what you think you might want to add. For comparison, here are the specs for the ($30usd) teensy++2.0(www.ebay.co.uk/itm/Teensy-2-0/221541256601) :

8-Bit AVR Processor (AT90USB1286)
128K Flash Memory, 8K RAM, 4K EEPROM
USB Can Emulate Any Type of Device
Single Pushbutton Programming
Arduino Compatible
8 Analog Inputs
46 Digital I/O Pins
9 PWM outputs

and the ($20 usd) Teensy 2.0 :

8-Bit AVR Processor 16 MHz (ATMEGA32U4)
31.5K Flash Memory, 2.5K RAM, 1K EEPROM
USB Can Emulate Any Type of Device
Single Pushbutton Programming
Arduino Compatible
12 Analog Inputs
25 Digital I/O Pins
7 PWM outputs

note the difference in analog (faders, knobs) and digital (buttons, switches) IO pins, and think about what you might want to add down the line to decide.

You can use any Teensy controller, arduino, any arduino clone, or any microcontroller that says it has a teensyduino or arduino compatible bootloader. Almost all of the controllers on this page would be suitable for the application I've described.

A breadboard is a rectangular plastic block that is covered in holes with contact clips inside them that you push wires into to build a prototype of your circuit before you do any soldering. It consists of two power "buses" (common contacts) that run down each side, each with a positive and negative hole. In the center are two banks of holes that are arranged into rows of 5, in which all of the holes in each row are connected.

This probably sounds pretty confusing but they are very easy to use, and allow you to quickly build, troubleshoot and test your design before soldering anything, and when you do solder, you can just go piece by piece from your breadboard. This video actually shows a light-controlled midi controller being put together on a breadboard using a Teensy, and shows it interfacing with ableton in real time. Take note of how the power buses on the sides are used, and how the board sits over the ravine, otherwise all pins opposite each other would be shorted to one another.

This page explains how breadboards work very well. In the videos of the teensy on the breadboard, the controllers are the version with header pins to be used with breadboards. This will make it much easier for you to prototype your design, then when it works how you want, you can actually transfer it to a "permanent breadboard" that has holes through the board surrounded by solder pads that you will solder you circuit to once you drop all the wires and teensy pins through the board. If you get one like this that has the exact same layout as a standard breadboard you can literally lift it off the breadboard and drop it into the solderable board if youre gentle. If you can get scrap wire and solder materials (be sure to watch a few videos on soldering ICs and microcontrollers, as the teensy really is teensy, about 17mm x 35mm, so you can imagine how close the pins are. Soldering really isn't difficult if you are patient and prepared though) and build you own enclosure, you can easily keep this under budget.

I would definitely agree with Snap Circuits. They delight my BD3 (who may understand at best the very basics), and I expect that it will serve more of a learning purpose in future years.

Two other suggestions which are both logic/coding based but may appeal to a child with budding STEM interest:

  • Makey Makey: I've used this with children ages 6-18 and generally get the same excited responses regardless of age. With older children, I tend to use as a way to introduce to "real" electronics. You can combine with Scratch, so she can design her own games/programs. Feel free to shoot me a message if you want to ask questions about this.

  • Robot Turtles: I've not used this personally, but I've only heard positive things about it from friends and colleagues who have played with their children
u/myearcandoit · 2 pointsr/ElectricalEngineering

Yes, perfboard, breadboard, protoboard. These are all correct although "breadboard" often implies the solderless type like this (more info here).
You connect a resistor by bending it's leads and pushing them through the holes. Then you solder them onto the board on the other side (you know what resistors look like right?)
Usually I place all my components on the board and then wire the components together according to the schematic. Here's an idea what the back side might look like.
In the end it is rare that the board and the schematic look at all similar.

Do you have all the components you need?...
Nevermind that for now... To Youtube!!
There is soooo much material on youtube. I searched "how to populate a perfboard" and clicked a random vid. Looks promising. I didn't watch the whole thing, but clearly it's related to what you're trying to learn. Likely there are better tutorials, it's just a matter of searching and watching.
Good luck! Don't be afraid to break things :)

u/mouseasw · 1 pointr/ADHD

I've got a few that I like:

  • Bike Chain Fidget - It's a couple of bike chain links connected with keyrings. It's super-simple, small, and easy to take wherever.

  • Tangle or Tangle Jr. - My wife bought one for herself first, but she and I both liked it so much that we got a couple more. The one I have at work has a rubbery clear silicone coating which is a little unpleasant to my touch, but it has two more segments than Tangle Jr. which means I can form it into a variety of geometrically interesting arrangements. My ideal version would be hard plastic without the silicone, but with 20 segments instead of 18. My wife claims they can snap apart, but I think this is not intended in the design since it results in it coming un-done when you don't want it to.

  • Hand Spinners - There are a lot of variations in both style and quality. You can get a cheap one for a few bucks, and those work just fine, or you can get a nice one with quality plastic or metal body and a high-end ceramic bearing for the center. I made my own using a laser cutter, and a neighbor used his 3D printer to make one. I'm considering buying a nice metal one in the near future. Whatever you do, get one with caps for the center bearing, it makes holding the spinner 10x easier.

My 4 year old understands Set if I limit the variables a bit (like picking only 1 colour to play with) so your 5 year old could probably play. She also likes Rush Hour which is a solitaire game, but I set up the scenarios for her. She’s starting to get into Quarto which is a bit like Set mixed with tic tac toe.

Labyrinth is a pretty easy game, though she lost interest in it pretty quickly (probably due to the overwhelming cuteness of Pengeloo which came home shortly after).

u/dremme · 1 pointr/Multicopter

Hey! I actually had very little knowledge of drones/electronics, and then I started lurking on this subreddit and became inspired! I did a bunch of research first, which pretty much consisted of watching build videos and googling "how do I build a quadcopter". I made sure to google any words or lingo that I didn't understand, like "what is an ESC", and "how does a flight controller work". I also tried to search this subreddit for things like "what flight controller should I use" and watched a lot of build videos.

Once I had a decent understanding of the basic parts and components, I bought a toy grade RFT quad, flew/crashed it, and took it apart to look at the various components. I also decided at that point that I wanted a deeper understanding of electronics, and bought this book, though I think that step is highly optional and not required to build a quad. I started working through the book, and also bought this soldering practice kit. After completing the practice kit, I felt more or less ready to try to build this tiny whoop.

Since this was my first build, I tried to keep it simple. It really just consisted of some very easy soldering and then putting the rest of the parts onto the frame. If you'd like more specific instructions or explanations of anything I did, let me know! I think this build could definitely be accomplished by anyone with a desire to learn. I learned a lot along the way, and I'm already planning a bigger more complicated build.

Something along these lines would be a good place to start, just to get more comfortable with soldering in general: https://smile.amazon.com/gp/aw/d/B0002LUAL6

Or honestly, any other kit that looks interesting to you on Amazon, Adafruit, Sparkfun, etc.

Specifically for mechs, grabbing some switches from a switch tester and playing around with small boards like these could be a good follow-up step to get direct experience with what you'd be doing when assembling your own board:

yeah it's good to be able to make custom lengths with solid wire but i think jumpers they are generally easier, pretty fast and neat. (this kind of thing: https://www.amazon.com/microtivity-400-point-Experiment-Breadboard-Jumper/dp/B004RXKWDQ).

i think i had a similar plan with big muffs, i actually made a vero version with all the variable components socketed and the intention of being able to try all different cap and resistor values, transistors, diodes etc... and it's had the same values since i put it in the box.

u/Nakotadinzeo · 3 pointsr/DrStone

Well, a love for Dr Stone is a love for science. I don't know how old your brother is, but when I was a kid in the 90's science kits were way more common. I've seen some in Walmart and there's this $5 store called 5 below that has some but I'll look on Amazon and see what relevant kits I can find.

here's a telescope for $33. Senku's thing is space. Space is awesome. You may also consider seeing if your local college has a telescope, I was surprised to find out that mine does and it's open to the public!

Here's a crystal growing kit. Chrome loves rocks.

Here's a microscope and here's the one I lusted after after I saw one on TechTV Screensavers $18 so cheap now! Tempting...

Electronics kit!! I had one of these! My parents threw it away because they said I was obsessive about it.. now I watch Big Clive tear apart garden lights... Senku make a radio too, which I think you can make a crystal AM radio with this kit if I remember correctly.

u/unstuckbilly · 2 pointsr/Parenting

I have a 7 yr old girl (and 5 yr old boy) both of whom love science & any type of hands-on activity. I emphasize hands-on because I would suggest not getting a DVD set or book set.... kids are more apt to get excited about actually DOING science (oh, and I'm a former science teacher too). My daughter also enjoys reading science books & I just let her go wild at the library & she always finds something that surprises me.

We got my daughter "Snap Circuits" last xmas and BOTH kids love it. It's a little hard for them to do alone & MANY (most?) of the circuits/projects are over their heads conceptually. Regardless - this is a set that they can both use for years (in the reviews, there are many teens and pre-teens who enjoy experimenting), and it DOES help to show the basic concept of what a simple circuit is/does and what components may be present. They have come to understand that a circuit includes a closed loop, power source, etc... Looks like their smallest model is less than $30.

Another thing that both kids have loved is just a basic "science experiment" kit that my bro-in-law gave her for her 6th b-day. I was opposed to ever buying one of these sets b/c so many of the ingredients are just simple household items - I thought I'd much rather have them experience the "magic" of science via materials in the kitchen cupboards. But - the kits are really great & provide a lot of instruction & explanation & include things that you wouldn't necessarily have on hand. I think they're actually well worth getting (and contain lots of fun pipettes & test tubes/etc). I can't find a link for the one she got, but search Amazon & you'll see lots of selection for $20 or less.

u/pseudo_lemon · 1 pointr/learnpython

Do you mean that you want to know why coding is important? Or do you want to know to learn how to code in a way that you physically feel and understand what you're writing?

I feel like it's the latter, there are a few different ways you can approach this.

  1. If you want to learn how to think in specific sequences, you can buy this Robot Turtles board game. It's fairly rudimentary, but you learn about why order matters and how to think about some task as a set of actions and loops.

  2. Similar to Robot Turtles, Alice simplifies the coding process with the purpose of creating 3D animations, stories and video games. It's still rather simple, but that's purposeful to remove much of the overhead so you just are thinking about what actions need to happen to create what I want.

  3. If you are fine with using a full programming language and the problems you've been doing, but are confused by magic box that is just running code, then something like Python Tutor will help. Python Tutor helps you slow down the execution and lets you go step by step to and follow along with exactly what's happening in your code (similar to using a debugger for those who already know how to use one). And it lets you do this in more than just Python. It has most of the programming languages you'll encounter (Python, Ruby, C, C++, Java, Javascript, Typescript).

    Best of luck on your journey.

I suggest this:

It's a very good kit, and will give you plenty of practice before you solder your Poker 2. No frills, and will give you plenty of practice for through hole soldering.

Combine this with a practical, but good quality soldering station:

http://www.amazon.com/Weller-WLC100-40-Watt-Soldering-Station/dp/B000AS28UC/ref=sr_1_3?s=power-hand-tools&ie=UTF8&qid=1406762091&sr=1-3&keywords=soldering+iron

A desoldering pump:

http://www.amazon.com/Sucking-Vacuum-Desoldering-Solder-Remover/dp/B005GIPKOW/ref=sr_1_3?s=hi&ie=UTF8&qid=1406762167&sr=1-3&keywords=desoldering+pump

And some solder:

http://www.amazon.com/Alpha-AT-31604-60-40-Solder-Ounces/dp/B00030AP48/ref=sr_1_1?s=power-hand-tools&ie=UTF8&qid=1406762345&sr=1-1&keywords=solder

To learn, there are plenty of Youtube videos, I recommend you also solder the Elenco kit, then desolder everything to get a feel for how the desoldering pump works (it's super easy, you can't really screw it up). Then, solder it together one more time for extra practice.

All together, about $66 bucks. Add in the cost of the switches, and you're looking at a little over 100. Still a bunch cheaper than the Poker 2 from Massdrop ($143.50), and you've just learned a life skill. For me, that's totally worth it, but then again, I'm an engineer, and learning useful skills is what my entire profession is based on.

Cheaper and has more soldering points. The other one has a shitty speaker which doesn't add much to the soldering lesson, but drives the cost up.

Hijacking to give some tips on toys and fun activities that can help solidify all this in your brain if you're more of a tactile learner (don't feel bad that these are "kids'" toys, as most of the people I know really only use their children as an excuse to buy them...):


Snap circuits help you get the idea of electricity transmitting information. Plus the informational material is written for someone who is actually nine.

https://www.amazon.com/Snap-Circuits-SC-300-Electronics-Discovery/dp/B00CIXVIRQ


Then you can look at how those work a little further using Arduino:

http://www.dell.com/en-us/shop/accessories/apd/a9335657?ST=pla&dgc=ST&cid=302851&lid=57581044&acd=1230980731501410&ven1=A9335657:54715087668:901pdb6671:c&ven2=:&ven3=272703650778773293

Lego robotics also use Arduino:

https://www.fractuslearning.com/2016/08/29/making-programming-lego-robotics/

You know how Lego has that picture by picture guide to building? Imagine learning robotics that way. My daughter at some point decided she didn't want to use Lego for whatever reason, though, so she's getting this for Christmas:

http://www.robotshop.com/en/makeblock-mbot-ranger-3-in-1-transformable-stem-educational-robot-kit.html

I realize these are costly items. But there are also budget versions and we also use programmr to help understand how code actually executes actions in an environment.

If you're interested in learning more, or if you know someone who is (especially a kid), hands on is really the way to start. Otherwise they'll be like me and take apart your electronics to see what's inside... that's also fun.

u/shinigami052 · 3 pointsr/DIY

Electrical engineer here...if you want to get into micro electronics and digital circuits (and you're a total beginner) go pick up one of those kits for kids. There are some that are very helpful for teaching you the basic of circuits (Ohm's Law) and stuff as well as helping you troubleshoot simple circuits. You don't want to jump right in with a fx generation, oscilloscope, DMM and try to make a complex circuit using ICs and MOSFETS and stuff as you'll just get frustrated and confused (as well as damage/destroy components).

You really don't want to skip the basics. Even in college we all ended up destroying so many resistors and chips while bread boarding things that we actually ran out of some components and some of us couldn't finish our labs.

It's a great and fun hobby to have with a great community of very smart people (especially if you get into things like Arduino, Raspberry Pi and stuff).

TL;DR: Learn the basics, get a child's electronics kit and go from there. Work up to all the other things.

I have done this for cruises a couple ways. I took a game box about the size of a Ticket to Ride box and collapsed about 20 games into it. It was pretty compact and you could definitely use a smaller box to fit and compact more games in.

The other way that was a bit easier and lighter was I took a 500 card count deck box and put 4 decks of cards in it: A rage deck, 2 decks of playing cards, and a pyramid deck (I used a Great Dalmuti deck for this one). I then used the rest of the space to fill with counters using these plastic cubes. You could also magic marker values on some of them for specific games. Jaipur is one that could come to mind.

There are geeklists like this one where people have figured out how to get creative with rage decks. With the playing card decks you can find a cheap playing card games book, and a book like all the Pairs variants for the pyramid deck.

If you're working from a book rather than a kit, you can order parts, even in ones, from suppliers like Digikey.com For orders under $25, they charge an extra $5. Even so, they're much cheaper than Radio Shack. Also, look up Sparkfun Electronics and their collection of books, kits, and free online projects.

At the minimum, you'll need a multimeter (volts, amps, ohms). Check ebay for these. A soldering iron is a useful tool, but a cheap one can be more trouble than it's worth. Better to use a solderless prototyping board (see Amazon or Digikey) at first.

First of all props to you to introduce your son to electronics and ask to find a good method for him to learn it out of interest.

I remember having electronics kits which had a bunch of simple components connected by those metal spring terminals. They often came with booklets to go step by step through simple projects to gain some understanding.

Perhaps you could look at toy shops and see if they carry some educational electronics kits? I remember book shops also sold them though I'm not sure if they'd still.

I found this on Amazon, seems a bit different with magnets snapping together but looks like it goes step by step in explaining: https://www.amazon.com/Snap-Circuits-SC-300-Electronics-Discovery/dp/B0000683A4/. Looks a bit expensive but not sure if that's different in the US.

I haven’t found the perfect distraction yet, but this thing does the job and I personally would suggest giving it a shot. They also twist up to be fairly small (or at least mine does) when not in use.

I'd recommend a snap circuits board to teach them about electricity. Something like this.

Anything with simple machines (screw, ramp, pulley, wedge, lever, wheel, etc.) that they have to assembly is also a good idea but most will require the ability to use a screwdriver and limit their ability to experiment on their own. Those that don't will likely be a little lame like simple kinex and lego stuff.

Finally chemical sets are nice but will definitely require adult supervision.

u/lolheyaj · 1 pointr/Quadcopter

Hey bud, I think it's great that you're interested in this hobby and am happy you're doing some research before plunging in. Do you know how to solder yet? That's an important skill in building your a drone since nearly everything in the building phase will require it. I had to start out with a little soldering practice kit before I started building a quadcopter. Soldering with a quadcopter can be difficult because everything is so small!

If you've got soldering down though, and you want a good starting kit that comes with pretty much everything, you can find some on eBay for pretty good prices, I've built four ZMR250 DIY kits purchased on eBay over the last couple years and they've all flown great. (That kit isn't totally complete though, you'll still need a transmitter/receiver and batteries.)

That kit is about £61, you can get a FlySky FS-T6 transmitter which comes with the receiver for £35 which leaves you over £50 to cover a couple batteries, a LiPo Charger, other misc electronics/parts you might need like voltage regulators or connectors and shipping. (which might end up being a little over £150, but that's how this hobby tends to go..)

The simplest is to use a radio chip like from Silicon Labs - 99% of all radios you'd buy from Walmart, etc. use these chips these days.

They are designed for "digital" so they have SPI controls to set tuning. You'll want a custom PCB for these but it only requires power, clock, SPI microcontroller, antenna, and audio power amplifiers.

You can also build "old school" discrete FM radios using discrete parts (e.g. transistors or older FM ICs). Google for circuits for these. They are strictly more complicated to build.

Ones like this are "minimally functional" - it's not high fidelity. These are so-called "super-regenerative" radios which can product radio interference or added noise in the audio. But it's quick-and-dirty easy.

A superheterodyne is better but far more complex. You need IF transformers and more circuitry. Strictly the Silicon Labs are implementing a superhet internally. I recommend an FM radio kit rather than design/build your own completely from scratch.

I have had the A6000 for a couple years now. Love it.

No matter what the camera you own the primary thing to get good exposure in low light situations is a lens designed for it. Don't get me wrong, the camera and it's sensor matters. Just not as much as the lens most times.

For the A6000 your going to want to use a super fast lens. I use either my Rokinon 12mm f2 or the Sony 50mm f1.8. The other advantage is to get some bounce cards and use your flash.

If you don't want to drop the money on a lens, the bounce cards are the cheaper route. If you want to spend the money on a lens, great, you can also afford the bounce cards. Get em.

Outside of that, you can shoot in shutter priority or manual depending on your skill level. The trick is to make sure your aperture is as fast as possible for the lens you are using. This will allow you to lower your ISO and keep your shutter speed as fast as possible as well.

As for the open box previous settings. Go into your settings and do a factory setting reset. From there, do a ton of research about the settings. If you don't understand a setting, leave it alone until you do.

BH photo video does a decent intro video on the A6000.

You can also check out Gary Fong on YouTube who works with the a6000 a lot.

This might be a bit much, but I want to help inspire the next generation of women scientists. Might I suggest a rock tumbler at some point? Perhaps make some nice Jewelry, or just simply studying the stones that come up?

u/femanonette · 9 pointsr/freebies

According to USPS it'd be about $7 USD. It'd likely take a few weeks to get there too.

EDIT: Found it on Amazon.UK for £0.98 with free shipping. So now you can have that exact model and save some money.

And here's an Amazon link for $1.62 USD for the same model if anyone is interested in buying it instead of hoping for the freebie.

Toy robots like Transformers Rescue Bots might work for her age. As she gets older, introduce her to toys like Snap Circuits to help her learn about electronics. Understanding about electronics will come in handy for anyone who likes building robots.

u/diggieshig · 1 pointr/pics

A great way to get started with this stuff is through a company called SparkFun based out of Boulder Colorado. They sell two kits both for about $100:

  1. https://www.sparkfun.com/products/12060
  2. https://www.sparkfun.com/products/13154

    These kits come with all the sensors, LEDs, transistors (controllable switches), and a really easy to read tutorial book to take you step by step from blinking an LED to controlling stepper motors.

    $100 can be a bit much so if you don't care about looks as much/want to buy sensors as you go you can buy the Arduino (https://www.sparkfun.com/products/11021), Breadboard (http://www.amazon.com/BB400-Solderless-Plug-BreadBoard-tie-points/dp/B0040Z1ERO), a refill kit (https://www.sparkfun.com/products/13110), and a few transistors (https://www.sparkfun.com/products/521) for about $50 bucks and then all of SparkFun's tutorials are online (https://learn.sparkfun.com/tutorials/sik-experiment-guide-for-arduino---v32/experiment-1-blinking-an-led). These include all the code, how to use the sensors/wiring, and anything you want.

    Good luck!
u/phineas1134 · 1 pointr/MechanicAdvice

This is really excellent advice! Sometimes just staring at a book is not going to make it stick. Another fun way to get some hands on electronics experience is with those project kits built to teach kids. Doing all of the projects in something like this or this shows you a lot of the theory in a way that will stick better because you have actually seen it work. And they cost less than a text book.

An electronics learning kit like this one always interested me. I've since played with electronics as an adult and I'm sure I would have loved that as a kid.

u/CaffeinatedGuy · 2 pointsr/Random_Acts_Of_Amazon

Wow, you guys have a lot of toys.

The nerdiest things I own are electronics project kits. I got my first one as a kid, this one, the 130-in-1 (a different brand, but exactly the same, down to the colors).

While in high school, I found a great deal on this 200-in-1 kit that had a little slicker layout and meter on the front.

Towards the end of high school, I went to radio shack and picked up this beauty, which has a breadboard and a whole bunch of components. It comes with two books, Basic Electronics and Digital Logic Processors. The latter dives into ICs, all of which are included.

I haven't played with them in a while (too much external stresses), but when I do, I'm also going to learn how to program Arduinos to see how I can combine what I learn from each to make something really cool.

u/legopowa · 2 pointsr/electronics

There is competition, but they don't seem to emphasize learning curves, where they start with simple projects that grow in complexity as new concepts are learned. The kits seem like a hodge-podge of parts and a project book, without a lesson plan.

This is an ideal product, though it involves simpler circuits and targets 8-and-ups. I'm hoping to target 12-and-ups.

u/tonypedia · 2 pointsr/Cleveland

Cool project. The soldering should be pretty simple, and it's fairly easy to learn. I would recommend buying a soldering project kit, something silly like this: amazon link that you don't mind messing up and learning on.

> mine it yourself in the US is Sapphire.

It's highly unlikely that you're gonna be able to find any kind of a gem grade stone by visiting an open-to-the-public mine. And if you do find one, it'll be so puny and an ugly color that it wouldn't be worth the expense of cutting it.

However, I have a sneaky suggestion that poses some fun and excitement for you and she'll get a knockout gem in the end!

Start off buying an inexpensive but high quality rock tumbler. It'll come with a small amount of varying grits and instructions.

For sapphire rough you're gonna need silicon carbide 220 grit and a few weeks of patience.

Couple bags of 15mm alumina balls for filler material inside the tumbler.

Contact a gem cutter like this guy HERE, select the synthetic sapphire/ruby (or spinel) color(s) of your choice and ask that he cut up a quarter-boule into varies shapes and preform them into alluvial shapes in the 5-7ct range. This will allow you some breathing room for polishing so that you wind up with a handful of various shapes and sizes after tumbling. You would then (secretly) drop these lil beauties into your honey's gem gravel before the wash. You'd probably have to fill in the assisting staff at the mine of what you're doing. She then discovers the gems and picks out which one she wants to have cut.

You then contact Phil again, send him the piece(s)....and he cuts a perfect gem in the size and shape that you choose either from the tumbled rough or new material.

You save a bankroll, have a blast being sneaky and she gets a REAL sapphire or ruby for her engagement ring and is never the wiser. :)








u/dweezil22 · 1 pointr/webdev

I suppose I'm more optimistic about kids, regardless of how seamless tech is. I'm a child of the 80's and back then the concept of give and take with digital logic was practically non-existent. When I was young (less than 10 I'm sure) my dad asked me how I would teach a robot to walk to my neighbor's house. "Walk to my neighbors house" "No, you can only tell him to step with his right and left feet" "Step left, step right" etc. A spent probably 5 mins offering simplistic solutions that he shot down by having us run through the script and realize my robot bumped into a tree, or a dog knocked it over, etc. That conversation forever changed how I thought about computer programming.

Nowadays kids TV has more logic in it. Kids games are being explicitly setup to teach logic. Things like Minecraft go a huge way. Older practical tech like inbox rules or Excel spreadsheets has basic scripting and programming built in. A lot more kids will grow up absorbing these sorts of lessons. Hell I played a board game with my 3 year old daughter that was that robot story in friendlier packaging.

u/piercet_3dPrint · 1 pointr/PlantedTank

The easiest way to get Garnets ready for submersion would be to tumble them in a rock tumbler. You can get an inexpensive one (https://www.amazon.com/National-Geographic-Hobby-Rock-Tumbler/dp/B01LQCIL88 for example), or you can make your own with a round plastic container, a base with a simple motor, and some wheels or conveyor parts for it to sit on (one possible method: https://www.instructables.com/id/DIY-Rock-Tumbler/). You put the garnets in, add some water and course abrasive sand, then turn it on and let it tumble for a week or so, then switch to the next finer grit, eventually getting down to plastic beads and soapy water. You can also polish them by hand with a dremil tool and polishing compound, or with a buffing wheel. This is the better approach if you want to preserve crisp edge geometry. Some people also cut and facet them. If you have a very transparent garnet it may be worth looking at having it cut and faceted as they can be worth a fair amount. But usually garnets are pretty inexpensive. If there is a lot of matrix rock and you don't want to tumble, you can typically dissolve it slowly with oxcillic acid or muriatic acid. Some people also use small sandblasters for particularly nice specimens. Its ok if they are a little rough, the fish won't mind, but they might get algae in the cracks. They also sell Garnet sand so you can have big garnets sitting on a bed of garnet sand if you like the look. I have a whole jar of it for some reason that came with the house heh.

u/Beeftech67 · 1 pointr/boardgames

Crazy idea, but what about a Lords of Waterdeep style game? Not sure if you have played, but it's a fun game.

You can get a bucket of 500 misc colored cubes from amazon for $13.
Get some poster board, or something, and have the kids draw maps of the world. Block off certain sections, and each one of these areas of the world will produce goods (cubes)...you could say each cube represents: produce, technology, raw materials, "education." ...I don't know, something like that. Kids take turns placing units, and getting those resources.

Create a few "quest" cards (cure polio, space exploration, disaster relief, etc.) that need various amounts of resources to complete. Maybe a system where the kids could "invest" in certain areas which would allow those areas to produce more goods.

...just rambling here...

Snap Circuts is the modern version of my favorite toy as a kid... It's pretty easy to start on this and by the time he's able to safely use a soldering iron he'll totally be able to design and build circuts.

u/FruitbatNT · 4 pointsr/cars

Trial and Error

Stuff like aftermarket stereo (assuming a basic install of head unit + Subwoofer) are relatively easy, but also very easy to do very badly.

The basics are - everything needs Power(+) and Ground(-), and in cars a some stuff will get it's ground from the frame (door pins, etc) or engine block. Everything needs a fuse. If you're connecting a new wire directly to the Positive (+) battery terminal it MUST HAVE A FUSE OH GOD PLEASE READ THIS AND NEVER FORGET IT.

For example, on a basic head unit you have a bunch of wires, but they're all doing really simple things. 4 pairs ( 8 wires) are for speakers, each one has a - and a +. Then you have the main power, the ignition power, and a ground (used by both powers). Then you usually have a + and - feeding a power antenna/signal booster. So you really just have 3 things wired up - Speakers, Power, and Antenna.

If you really want to learn it, grab some cheap "Electrical experiments" kit and you'll learn quick how different components work together and what kind of mistakes you can make in a pretty low-risk environment.

Snap circuit sets are cool - they aren't necessarily something you play with afterwards, but since he likes putting things together, he can take apart and rebuild endlessly. It's for 8 and up, but if he can read on an 8 year old level or just follow the charts, he should be able to do it. He can also try his own projects. They're fun.

My 4-year-old son is very mature too and easily gets bored with typical toys for his age group. I totally recommend the Robot Turtles board game! It teaches children the ins and outs of programing (coding). My son plays it obsessively at his cousin's house. I guarantee your son will be hooked once he tries it. Plus NO BATTERIES! Bonus!!!

u/SirCheesington · 2 pointsr/Gameboy

Well then, before you take on any Gameboy soldering, you should get a kit like this and practice. The deluxe kit comes with a much better soldering iron though for only $20 more which will last longer. Finally, buy some rosin flux before you mess with the Gameboy, it makes modifying existing solder joints sooo much easier and more pleasant.

I'm an engineer at an electric utility and we use Snap Circuits to demonstrate basic concepts of electricity to middle- and high-schoolers. The kit has a lot of variety in the activities and is a simple means of experimenting with electricity. It's easy to assemble and reconfigure too, which is nice. I've spent hours at various public outreach events playing with this toy and would recommend it to kids and adults alike.

u/Spitsongoats · 2 pointsr/Parenting

My 11 yo son got snap circuits a few years ago and loved them. I think they'd still be cool for your son. Snap circuits are electric parts that snap together like legos and you can make projects such as a light that flashes or a siren. It teaches them about electricity and it's my favorite educational purchase ever. It's $20 for a basic kit that does about 80 different projects in increasing difficulty. They are rated #1 in science education on amazon. They come with everything.

u/dameon5 · 526 pointsr/atheism

I disagree that it should be mandatory. There should be reasonable exceptions to any rule. My niece is homeschooled. But she is currently 7 years old and her mother has a master's degree in education. The reason she is homeschooled is because my brother has a job that requires him to travel a great deal. So by homeschooling, the family gets to be together more.

My seven year old niece currently reads at a much higher grade level than she would be exposed to in public school (barring an accelerated program) and is also proficient in math and science (relative to her age of course).

For Christmas, I just bought her board games that teach programming and scientific concepts and both her and her parents loved them. And in her short life she has seen more of the world and been to more museums and historical places than I have at 39.

I have also talked to my brother and his wife about how they plan on handling her education as she gets older and they both admit that, as she gets older, they both believe they will need to place her in an actual school to ensure she gets a well-rounded education. But if she continues to learn at the rate she is now, there is some concern around her transition.

EDIT - Lots of folks asking about what board games. The ones I bought her this year are...


Gravity Maze


Code Masters Programming Logic Game

A few years ago I got her


Robot Turtles




I wanted to buy her this, but it was on back order and would not have arrived while she was visiting. I showed it to my brother and he told me to definitely keep that in mind for her birthday or Christmas next year.

Wow, thanks so much for the information! I've got this tumbler.

  1. How can I tell which rocks are hard vs soft? Should I make an ID before tumbling and categorize them?

  2. So it's less the size of the rocks that makes them shrink and more about hardness?

  3. That's super interesting, I never would have figured that out! The unfortunate thing is I don't get to go hounding very often, so it would take me a REALLY long time to have enough rocks. :(

> I do agree that DIY needs to improve and be as foolproof as possible, but right now the efforts are pretty good, for example with epipen alternatives.

To me the "future" lies in comparing which simple plant-based herbs and medicines (which can be cross-referenced against the pubmed tests) have already been mastered by Native populations (such as aspirin, alcohol, other teas and herbal crap.

This, to me, would reduce the commercial aspect of treating health as a "Value".

Thus the DIY would supplement but not fully replace Big Pharma. But in my view, with equipment for testing, there's not much holding back tomorrow's adolescents from building a circuit to test impurities or other measurements.

u/fatangaboo · 2 pointsr/AskElectronics

The RHS is pretty good, congratulations!

For the LHS you're attempting to use a floating (i.e. neither terminal grounded) 12V power supply, to synthesize -3.4V_with_respect_to_ground and +8.6V_with_respect_to_ground (3.4 + 8.6 = 12). I recommend you connect these supplies to two circuit "stages" . Stage1 is an NPN transistor circuit that takes (0V, +3V) inputs and produces (+8.6V, 0V) outputs. Stage2 is a PNP transistor circuit that takes (8.6V, 0V) inputs and produces (-3.4V, +8.6V) outputs. Or you can zener clamp the high level of stage2 so its outputs are (-3.4V, +3.4V).

It's a shame you went straight to dead-bug-on-groundplane soldered implementation, without first building on a solderless plugin protoboard. In its current form, trying out modifications will be difficult.

u/Brostafarian · 2 pointsr/MechanicalKeyboards

my personal recommendation is to get a soldering kit first and watch the EEVBlog tutorials on soldering: https://www.youtube.com/watch?v=J5Sb21qbpEQ part 1 is equipment, part 2 is throughhole, and part 3 is surface mount (which you don't have to watch). Part 2 is the most important; because you're just doing throughhole you can buy a cheap soldering station for like 25 bucks since throughhole components can take a bigger beating than SMD stuff.

I got the Elenco FM radio kit on amazon: http://www.amazon.com/Elenco-FM-88K-FM-Radio-Kit/dp/B004YHZE0G because it was cool and gave me more of an incentive to finish. This part is to just work out how to throughhole solder on something that doesn't cost 80-100 dollars; you'll probably feel like you have the hang of it after a couple minutes, but it's better to get that way before you start on your board

u/nullizygous · 2 pointsr/ElectricalEngineering

Just to add one more suggestion. I had something like one of these Elenco 130-in-1 Electronic Playground and Learning Center when I was really young and I probably built 90% of the circuits in the book. It's a lot of fun and they do a fairly good job of describing how the circuits work. You connect components using precut wires to "spring" terminals.

If you'd like to learn how to solder, here's a kit you can buy. You'll realize that it's actually quite a fun skill to have, and attempting the assembly of a keyboard might be something you'll learn you're interested in.

"But I have a lot of outdoors combat so this comes up a lot."

For outdoor encounters, I generally don't roll out the battlemat until combat is a sure thing. Unless there's some kind of kill-on-sight order or racial enmity, most fights don't start until both sides have had a chance to exchange words, well within 30' of each other.

So, it sounds like you're setting up a lot of encounters where either one side is ambushing the other, or the majority of encounters are solved by combat so there's no reason to approach to comfortable speaking distance. That's generally not the experience at my table (my players like talking but rarely plan ahead), so I can't say my solution addresses your "a lot" case.

In cases where one side is attempting to ambush another at longbow ranges or when I want to set up huge battlefields, I'll use a battlemat scaled so 1cm = 5' (rather than 1" = 5'), and then use centimeter cubes to represent Medium humanoids, standard 1" minis or tokens for Large size creatures, etc. This requires prep work, but like I said the long-range encounters are the exception rather than the rule with my group.

You could also run combat theater-of-the-mind style until the sides engage each other at a range that can be represented with your standard battlemat.

u/building_an_ergo · 4 pointsr/MechanicalKeyboards

After almost 4 long months, I have just completed my (almost) fully labeled Deep Space Ergodox

Parts Listing:

  • Aluminum top plate Case from mechanicalkeyboards.com

  • replacement purple plate from Falbatech

  • P3xon ergodox cable set

  • Deep Space Core, Polaris 100% Kit, Ergodox Kit, and numerous keys from Grab Bag

  • Two Black Metal Ravens from HKP

    I have always been a buckling springs fan.

    And then one day I saw the "Deep Space" keyset and fell in love.

    Since Deep Space obviously doesn't work on a buckling spring board, I decided to get a Cherry MX board.I was back home in the States for a month with a lot of free time, and I didn't just want to buy one so I started looking at kits. Once I saw the Ergodox I knew I had to build one.

    Unfortunately this was in Auugust of this year, so the Deep Space group buy was long over, and there was no groupbuy up for the ergodox (or infinity ergodox) either.

    Using the ergodox site I sourced and ordered the parts. I had never assembled anything using a soldering iron but decided to give it a shot. I used a cheap Amazon radio kit just to get a feel for it (I never got that damned kit working btw).

    The ergodox assembly went great. Had it finished in a day. It all worked first try. I had forgotten to order a TRRS cable though, so I had to wait an excruciating 3 days to find out though. After three months of use I discovered that I missed two solder points on diodes so the keys acted erratically, but that was a quick fix.

    I originally ordered it with blanks instead of Deep Space keys, because I wanted to test out DSA profile and they were considerably cheaper than the full Deep Space set. Once I decided I liked it I went ahead and ordered the Deep Space keyset.

    I ordered it a week before I planned on leaving the U.S. and it, of course, arrived an hour after my plane took off.

    I finally got the set a month or so later which was when I realized I made a mistake. Unfortunately I wasn't looking at the sets when I ordered. The ergodox Deep Space set is DRASTICLY different from my layout, and combined with the core does not cover the board.

    By this time 90% of the PMK Deep Space set was sold out, so I had to hunt for people selling it. I came across a great deal on mech market for the function keys and ordered those. I also managed to catch a grab bag which covered the rest of the board. A few PMK blanks and it was at least covered in the proper colors.

    As of this time I am still missing a 1.5 Return key in deepspace colors (do they even make this?) and a 1.5 Shift key in deep space colors (which only seems to be in the ergodox set which is a $44...and sold out). I'd also like to order a Planetary Set if it comes in stock to replace my Ravens with the Yellow Galaxy swirl.

This. You can find decent starting irons on Amazon with solder. You might consider buying a few ”learn to solder" soldering kits from Amazon. They come with all the parts needed, and the instructions teach you how to assemble the components (you then have to solder them in the board it came with)

The links for the JR. Snap Circuits which is what I used in summer camp for kids 4-12. Kids love them because they can try to make their own circuits and there's some really cool ones in the attached book. There're the really basic ones that just light a bulb but they get more and more complicated. Only warning is that it comes with a fan that can fly off and potentially cut someone, so I'd supervise him very carefully.

EDIT: The kit does say 8+ but you can use it with younger kids without too much trouble. I used to keep the batteries and just make sure it was all connected properly with the younger kids.

You-Should-Solder spiel:

if you have normal fine motor ability, soldering is easier than you think. unless you have an adustable iron turned up to max, or you're holding the iron on the pad for more than 5 seconds, you'll have a tough time ruining the PCB. Check out this comic, watch some youtube videos. If you want some practice before you embark on an expensive project, there are cheap kits you can get online.

I started with this kit. The iron it comes with is about as crappy as you can find, but it's served me very well through many projects, including building 3 keyboards, and unless it breaks or I need to do something very complex with surface-mounted parts, I don't think I'll need to replace it.

For a soldering kit, I used this one on amazon, it was great practice.

As for a soldering iron, look on ebay/amazon for a "936" soldering iron. Any of them are about the same, most are clones of the famous hakko 936.

The original 936 is too expensive in my opinion, I'm using a sparkfun clone 936 that unfortunately is no longer sold. Most of the other clones should be ok though.

The only think I would really recommend getting legit is a hakko chisel tip, like this one. Don't get those 10pc tip sets, they are cheap and it is much better to use just one good tip than a bunch of bad tips.

Lastly, if you want your tip to last a longer time, don't use a wet sponge, that can damage your tip. Use one of those copper hard brush things, I forget what they are called, but you can buy them at amazon/ebay.
