There are three pathways through the "technology jobs" jungle.

1. Computer Science / Computer Engineering / Software Engineering.
   

• All of these degrees prepare you to create or assist in the creation of new technologies.
  
• You might create new software, or a new mobile app, or even a new device.
  

2. Information Systems / Information Technology.
   

• These degrees generally prepare you to support or implement existing technologies.
  
• You didn't invent it, but you help keep it working, or help improve it to better assist the business.
  

3. Information Security / Cyber Security / Information Assurance
   

• These degrees generally prepare you to help secure businesses and their technologies.
  
• Some aspects of these areas are technical and complex as hell, often requiring Masters-level education for you to be an effective staffer.
  
  Those are guidelines, or rules of thumb. Those are not absolute mandates.
  
  A Computer Science degree can truly prepare you to fulfil any role I described above (Create, Support or Secure).
  
  Cyber Security is seriously complicated, and is not a great subject for an undergraduate degree. There is just so much stuff you need to know for CyberSec, it's best served as a Masters Degree subject.
  
  
  You can set into any decent college on day one not knowing a damned thing about anything I mentioned above and exit college 4-5 years layer perfectly qualified for employment.
  
  It certainly helps to be dabbling with technology now, as a High Schooler. But it is NOT mandatory.
  
  All you need is a spark of real honest interest, and the willingness to learn and explore beyond the classroom.
  
  Read that line a second time. Read it out loud.
  
  Those who attend class, take notes and then go back to their dorm and play SmashBrothers tend to not be especially successful in this career field.
  
  Those who attend class, take notes, ask questions in class, and ask more questions after class and hook up with fellow enthusiasts after class in a technology club, and participate in online exploration of more technologies, and build shit with technology in their dorms... Yeah. Those are the people who are going to move quickly up this career.
  
  Six-Figure salaries are NOT difficult to access in this line of work.
  
  You can be earning $100K before you are 25 down several of these paths, and before you are 30 down most of these paths - if you apply yourself meaningfully.
  
  Want to explore all of this for cheap?
  
  Consider buying a Raspberry Pi.
  
  If you have a desktop PC this is a super cheap and easy project.
  If all you have is a laptop, this is less easy and less cheap.
  
  https://www.amazon.com/CanaKit-Raspberry-Starter-Premium-Black/dp/B07BCC8PK7/
  
  $79 gets you a complete kit.
  You just need a keyboard, mouse and a monitor (which you might already have if you own a PC).
  
  Have a look in here: /r/raspberry_pi/
  
  A Raspberry Pi is a complete computer the size of an Altoids tin.
  It runs a version of the extremely powerful and flexible Linux operating system.
  
  You can turn your RasPi into a Web Server, or a Video streaming server, or an MP3 streaming server, or a Robot controller, or a Weather Station, use it to learn how to create software.
  
  It is an immensely powerful tool for learning and exploration.

  But I can tell you there is plenty of room for you in this career field if you want to join us.
  
  What do you think you'd like to learn more about?
  
  Pick a direction. Pick a buzzword.
  

Look up elegoo parts on Amazon. I know they sell a set with a (very good, EACTLY the same knockoff) Uno and a TON of parts. It's called the "Elegoo super starter kit". You end up with two unos, but that's not a bad thing in case you fry one. I think it's around $40 with shipping.

I'm sure they sell other parts too. Check them out on Amazon. IMO it is the best bang for your buck.

EDIT: it also contains a PDF with instructions on how to build projects with them. How to do the wiring and they explain the coding too. They do it in a way that they build off of what you learn.

https://www.amazon.com/Elegoo-EL-KIT-003-Project-Starter-Tutorial/dp/B01D8KOZF4

It's listed as the #1 seller for electronic kits. Its $35 and it has a 4.5 out of 5 stars.


Here is a kit with just boards.

https://www.amazon.com/Arduino-Raspberry-kuman-Projects-Tutorials/dp/B016D5L5KE/ref=sr_1_5_sspa?s=industrial&ie=UTF8&qid=1518807393&sr=1-5-spons&keywords=Elegoo+parts&psc=1

Elegoo also has these kits.

https://www.amazon.com/s/ref=sr_gnr_aps?rh=i%3Aaps%2Ck%3AElegoo+kits&keywords=Elegoo+kits&ie=UTF8&qid=1518807370

There are a lot of them, so go through each and see which parts you like.

Buying with Elegoo is way way cheaper than through Arduino.

------------------------------------------

I also found this really cool car that you can make

Elegoo EL-KIT-012 UNO Project Smart Robot Car Kit V 3.0 with UNO R3, Line Tracking Module, Ultrasonic Sensor, Bluetooth Module https://www.amazon.com/dp/B0746DVP1J/ref=cm_sw_r_cp_apa_goZHAb3MFJF93


.I would build the car first and have fun with it. Then I would take off the ultrasonic sensors and replace them with IR sensors. Then try to program it to solve a maze.

If you're interested I have a website that takes you through every step on how to make a maze solving robot car with Arduino.

It's really a good tutorial. He teaches you everything and explains everything. You build the basics of the car first and get it running then he tells you how to tweak and add things to the code to make it better at solving mazes.

Start small. It'll save you money, let you get your feet wet, and help you learn how to grow better, and then you can buy bigger.

My "starter package" is:

• A 2' x 2' x 3' grow tent - $55.
  https://www.amazon.com/gp/product/B00SWGYYWO
  
  
• A grow light ($90). I prefer COB's as they're easier to fix than blurples.
  https://www.amazon.com/gp/product/B01I4NY8KW
  
  
• A power strip zip-tied to a pole in the tent. Makes wiring prettier and easier. ($24) I chose a nice metal one, but you can use a cheaper one.
  https://www.amazon.com/gp/product/B00F8ZQYHA
  
  
• Hangers to hold the light ($8)
  https://www.amazon.com/gp/product/B0098R0600
  
  
• A fan and filter ($70), and variac ($90) to filter smell and move air to keep things cool. This combo is overkill for this tent, but I ended up using it on later tents so it's a good long-term investment. You can cobble something cheaper together with some work, but this "just works" out of the box.
  https://www.amazon.com/gp/product/B004Q2ER5C/
  https://www.amazon.com/gp/product/B006NGI8VS
  
  
• 5 gallon Smart Pot ($7) for growing, FoxFarm Ocean Forest Soil ($16.50), Plant saucer ($7) for growing. You can save some money here by shopping around. In particular, Amazon's price for FFOF is about double what I pay at the (very expensive) local "indoor gardening" center.
  https://www.amazon.com/Smart-Pots-5-Gallon-Soft-Sided-Container/dp/B002JUOWB2
  https://www.amazon.com/FoxFarm-FX14053-12-Quart-Organic-Potting/dp/B001I49Q98
  https://www.lowes.com/pd/Garden-Treasures-15-31-in-Rust-Plastic-Plant-Saucer/50445000
  
  
• Go Box Plant Nutrients. This should last you several grows.
  https://www.amazon.com/gp/product/B004PS4B08
  
  
• Seed of your choice (let's say $10).
  
  So for about $420 (heh), you can get your foot in the door and start growing. This is a nice setup too, you can probably save $100 by shopping around, buying used, or doing-it-yourself. I've left off a few odds and ends like dryer duct, Fiskers for trimming, weed fabric pins for low-stress training, pitcher for watering, Mason jars for storage, but you can likely find those or suitable replacements around the house without spending money.
  
  I also have a Raspberry Pi 3 ($43) with Sense Hat ($37) and metal case ($15) in each of my grow tents to log temperature/humidity and other things. I'm interested in eventually using the GPIO functionality to water my plants too. Not critical, but definitely a nice thing to have, especially if you're the hacker type. If you go this route, you might look at raspiviv.com too.
  https://www.amazon.com/gp/product/B01C6FFNY4
  https://www.amazon.com/gp/product/B014HDG74S
  https://www.amazon.com/gp/product/B0722L338Q
  
  I'm glad I bought a good intro setup because I still use it now that I've upgraded. I now have a 3' x 3' GG Shorty tent with HLG 300 LED for flower, a 2' x 2.5' GG Shorty tent with two 400W Roleadro COB's for veg, and my "intro package" is now my germination/cloning tent (and drying tent too since several people suggested that too). Being able to have three tents (germination -> veg -> flower) working simultaneously is increasing my output quite sharply. I'm doing this to help a relative with cancer, so you may not need to go quite as crazy as I did.
  
  You mentioned using 35+ gs (~1.25 oz) a month. You probably aren't going to be able to grow that much given the constraints of tent size and light wattage (plus being a first-time grower! You'll learn a lot!). So once you get used to it, you'll probably want to buy more stuff. Marijuana isn't addictive, but growing marijuana absolutely is.
  
  Once you've got your hardware, the variable cost is seed (~$10), soil (~$5), nutrients (~$20), and electricity (~$30). From that, I'm going to estimate you can grow ~1.5 ozs (you can do more as you learn more though). So you're looking at ~$40/oz after you've made the initial hardware investment.
  
  Hope this helps. Depression, cancer, and everything else can just go suck it.

I am assuming you use the euro, and you put dollars, so I assumed US dollars, which is probably wrong, but I am going to run with it :) . Doing the conversion math, it looks like you have roughly 401 euros to spend, or 338.70 pounds. If you meant 450 euros, even better! Let's assume 338 pounds. With that, if you shopped on amazon.co.uk you could buy 8 of these Raspberry Pi3 packages that include everything you need to get started the day they arrived. The SD cards are already imaged with the necessary operating system, good quality power adapters are included, with adapters for different plug standards, and a nice case. You would still have to consider shipping, monitors, and a regular HDMI cable for each Pi3. If you have older monitors with DVI ports, they make DVI to HDMI adapters that work great.

Wireless is not difficult to setup on the pi3, but if you wanted to make life even easier in a classroom setting, I would take advantage of the built-in ethernet port on each pi3. Just for beginning purposes, until you and the students are more familiar with the Pi3 and the operating system, a 10 or more port ethernet switch, with a wireless router plugged into it, and also connected to the internet, would allow each of the Pi's to get an assigned IP address over ethernet, which would also allow the Pi's to connect to the internet over the wireless router and browse the internet, download software packages to the Pi's, and, allow you, as the teacher to have control over internet content filtering and other things that would be important in a school setting. The wireless router can be configured to hand out DNS addresses, that point to a content and ad filtering server IP address that you control.

I'm pretty new to this too, I bought my Ender 3 Pro around the same time as you. Quiet printing is pretty high on my list as well as being able to print high-temp exotic filaments in the long term while maintaining reliability.

First upgrades I purchased were stiffer bed springs so I would be less likely to throw the bed out of level while removing prints or working around the printer and Capricorn XS tube since it has a more consistent internal diameter, fits closer to the filament, and can work with slightly higher temps. I also picked up a pack of bowden couplers recently as I noticed the end nearest the extruder is sliding past the coupler jaws on de/retraction; don't worry about that unless it's an issue for you. That's about $30 alone since I don't have a supply shop locally and have to order those parts in bulk. I had a Pi 3B laying around unused and flashed Octoprint onto it. Highly recommended. I have a replacement Noctua hotend fan, buck converters, and 5015 blower on order to quiet the fan noise; about $32. Just replaced the Meanwell psu fan with a 60x25mm Noctua I had lying around (Note: there may be better options in the 92-120mm range to replace part of the PSU housing, but that's what I had laying around). Next upgrade coming is the SKR Mini E3 with TMC 2209 drivers ($28) to eliminate almost all of the stepper noise. Also looking into a replacement for the control board fan and some vibration isolating feet for the frame. As far as higher temp printing I haven't made a lot of progress aside from buying a titanium all-metal heat brake ($11) winch I have yet to install or inspect, and looking into enclosure and electronics relocation avenues.

Either way the mods I purchased came in at around $100 US which should quiet the printer and help with reliability. Also looking into picking up a good M3-M4 bolt kit if any exist in the US.

Here are some links to the things I picked up and will, which may be helpful if you're in the US. Mostly from Amazon.

Kind of a tie for me between two items:

First is a Raspberry Pi kit. I have been looking at getting more into this, but hadn't found a project that I thought would be worth spending the money on. Although it can be used for myriad things, this particular kit is meant for retro gaming. It can play anything from Commodore64 and Atari to Super Nintendo, Genesis, PS1, and possibly PS2 (haven't looked into it yet). It is basically my entire childhood smished onto a microSD and a small circuit board, and it will allow me to pass my love for those games onto my kids. My younger son, especially, loves trying out new games, and even is into some that I was never into, like sports games. He's tried a few of my old SNES games on an emulator and loved them, but didn't like the keyboard controls. Not only that, but it will give me a project to do.

The other one is a variable temperature electric kettle. I don't know how much of a tea drinker you are, but using the proper temp for the type of tea really makes a world of difference. For comparison, it's like going from nasty, generic dining hall cheap-o brand coffee to high-falutin' gourmet stuff from a civet's ass. Brewing the perfect cuppa can be difficult, if you have no way to measure temps, going more on instinct and hope. This kettle saves you that trouble and brings it up to the proper temp, and keeps it there for you.

Awesome contest. Thanks for the opportunity!

If you mean the button , no you don’t need an extra board but you you can’t connect it there , it doesn’t know you pressed the button because it’s off .

A workaround is to get a power supply with a power switch.

Turning off works because the rpi know you pressed the button and does the required action .

The cable you’re looking at is called ‘jumper wire ’ , and you also might want a breadboard

Turning on doesn’t need script because you’re just closing the circuit to allow current pass through then powers the pi .

For the turning off part , you do need scripts , it’s more like telling the computer what to do , you need to tell the computer what to do when you pressed the button , more precisely, you also decide which coding language you want to code it in , and there’s python , that’s where the pi name came from , c mostly known because it’s the language in arduino ide or just simply Linux that you type in the terminal in the pi

Good luck and when you meet any issues, just post it here .

Glad to help:)

Good luck on your build

Thanks. Searching for separate controllers led me to a few RetroPi preloaded emulation kits. I might forgo the controller though if I can figure out how to connect a PS3/PS4 controller via bluetooth. I'm also looking through some of the included hardware one this and this to get some ideas on possible upgrades. I'm not too familiar with different types of heat sinks or if a case with a fan mod will be a lot of use unless I go full bore and try to overclock the RPi, but you definitely gave me a good place to start on my search. I've still got a lot to learn about it, but the more I read about the setup, the more I'm starting to think I might need to buy one for myself too lol.

He's also more of a console gamer with a love for nostalgia, so I don't think he has a computer capable of running a Nvidia gpu, but that definitely made me realize I might need to check more into the software before I get too wrapped up in the hardware.

Another good and cheap way for a camera is a Raspberry Pi Zero W with a small camera and this installed on it:

https://github.com/ccrisan/motioneyeos

You can set it up to email you photos, videos, upload to the cloud, ftp, etc - total cost for a complete camera with be around $50.00. It's the cheapest full wifi IP camera you can do - parts I've used:

https://www.amazon.com/gp/product/B071L2ZQZX/

https://www.amazon.com/gp/product/B01LH10HYE/

You can fit the whole thing inside the case provided by the Canakit - just use the one -without- the camera hole (it doesn't fit that camera) - and drill your own hole. Hot glue the camera in place. You'll have to come up with your own solution for a mount (I ended up drilling a hole in the back case, putting a 1/4-20 thin-pan-head screw in and a standard camera mount).

Or get a a bigger case for the whole unit - a cheap decoy camera can make a great custom case:

https://www.amazon.com/gp/product/B00MC05K9W/

https://www.amazon.com/Security-Surveillance-Realistic-Recording-Warning/dp/B01HDZM66K/

Those are actual cases that are used by "cheap" security camera makers, just with false parts and a blinking LED added. So they are easy to repurpose for custom security cameras made with RasPi components. Also, the larger cases allow you to stick something bigger than a Pi Zero inside - a full Raspberry Pi 3 or 4 could be fitted in there, plus a larger (more pixels) camera module if you wanted it (plus anything else you could think of - IR illumination, temperature and humidity sensors, etc).

The only thing cheaper than a RasPi security camera system like this would be the ESP32 camera modules:

https://www.amazon.com/gp/product/B07QS7VFMJ/

But they aren't as easy to set up and use; software is still a very-much hands-on experience (if you know Python, though - they can fun little units). You'll have to come up with your own enclosure, too. But if experimentation is up your alley, they are the absolute cheapest option for an wifi IP camera.

So setting up my cluster I purchased 3 Raspberry Pis on amazon, a network switch, and a 6 port usb charger all found below:

• Raspberry Pis: https://www.amazon.com/gp/product/B01LPLPBS8/ref=ppx_yo_dt_b_asin_title_o06_s00?ie=UTF8&psc=1

  To get started with this setup you'll need to flash Raspberrian os to each sd card. You can script this pretty easy if there are multiple systems your deploying and it is honestly a good starting point for batch scripting etc. Depending on your experience with Linux systems, you'll either want the full os for Raspberrian or the Lite. I prefer Lite since it's just command line interface and has faster deployment/setup time.
  
  Once you have your pi's flashed with a linux based os, you'll need to start installing kubectl onto each node and kubeadm onto your master in your cluster. There are several articles such as this one that provide easy to follow setups for raspberry pi k8s clusters.
  
  Once you've gotten your cluster setup, I would try deploying a web api to your cluster and exposing it within your network to learn most of the basics of kubernetes/docker deployments. Most examples online use NodeJs applications as examples. They also usually deploy using docker images as well. Docker and K8s go hand in hand for most of your apps in your cluster. For my setup, the K8s repo had/has a lot of already made scripts and setups for your needs. All of my stuff I used came from their repo or multiple Medium articles.
  
  Here's some useful links for getting started. I'd also check out the r/kubernetes subreddit. Most of the articles are a few years old, but generally the top hits on google for kubernetes raspberry pi are enough to get you going and setup. It took be about 2 months of on off working to get mine up, stable, and secure with RBAC permissions before I moved my own apps into my cluster from GCP kubernetes cluster (Google Cloud Platform). My hassles also came from trying to much at once but that's just my nature:)

I'm pretty new to it too, and for me, buying the kit (power cable, hdmi, preloaded microSD, etc.) was a good route. Then you have a choice to make - is it a tiny linux server for you, or do you want to play with making stuff? I am pretty new to it all, but the Raspberry Pi T-cobbler + ribbon cable + breadboard kit (transistors, leds, wires, etc.) was the right combo for me to start learning. From another newbie, the best advice i can give is to watch your voltages!

My Pi: https://www.amazon.com/gp/product/B00L87YMGM/ref=oh_aui_detailpage_o06_s00?ie=UTF8&psc=1

The add-ons:

More storage:
https://www.amazon.com/gp/product/B00DTZA5S0/ref=oh_aui_detailpage_o03_s00?ie=UTF8&psc=1

With all of that, plus an outlet/box/misc wire from the hardware store I'm now able to control an electrical outlet remotely - pretty basic, but a huge deal for me.

I think I'm similar to you in skill level and I was able to do it. I bought a canakit like this one...

https://www.amazon.com/CanaKit-Raspberry-Starter-Premium-Black/dp/B07BCC8PK7/ref=mp_s_a_1_6?ie=UTF8&qid=1540821578&sr=8-6&pi=AC_SX236_SY340_QL65&keywords=pi+3b%2B&dpPl=1&dpID=51QERaUXmBL&ref=plSrch

It comes with an SD card with noobs (operating system) installed. At that point setting up pihole was just running a command line and following a few prompts be and it was all set up.

It's probably not the cheapest or best way to get started, but for me paying a little extra cash to ease my way into working with pi was a good trade-off. Overall I think it was like 30 minutes from opening the box to having pihole functioning on my network.

I'm pretty sure you could do something similar with a pi zero. I bought the 3b+ bc I wanted to explore pi and it's potential and again the $80 wasn't a big deal.

Well, it looks like you got plenty of good answers already so I won't really go over it all again. For one, for the rpi camera, you can buy longer camera cables for it, which is what I did since they give you stupid short ones when you buy it.

Amazon has a bunch of them, I just bought several for mine and they work great.

Also, don't forget about maintenance supplies. For these (found them on Amazon as well) you would need to have some microfiber cloths and some type of grease (I went with the Superlube brand pretty much everyone loves). I have only been using PLA myself, but I get the PLA Plus from monoprice.com, it's priced well and builds good. I haven't had any issues with it.

Once my Prusa gets here (a good wait for me sadly) I might start looking into other filaments, but honestly PLA has done everything i have wanted it to up to this point.

Thank you so much for your response. As edited in my original post- I'm going to spring for both I think. As someone with literally zero experience with Pi how long (rough estimate) do you think it will take to get up and running? I teach high school but also am the commissioner for an athletics league managing 16 Athletic Directors... Also just recently married and adopted a puppy, haha, so my time is sparse, to say the least. Is the Pi something I can tinker with here and there as time opens up or should I really commit a dedicated day or weekend to really indulge and focus on it?

I am looking at this on Amazon... https://www.amazon.com/CanaKit-Raspberry-Complete-Starter-Kit/dp/B06XW6VX1H/ref=sr_1_1_sspa?s=pc&ie=UTF8&qid=1510767226&sr=1-1-spons&keywords=rasberry+pie+3&psc=1 is this the right direction? Cheers!

I thought it'd make sense to list all this information in one place:

• Here's the starter kit I used to make them. They're currently on sale for about $60.
  
  EDIT: I realized in hindsight that this kit runs with 256mb 512M of RAM. For the same price, you can get the another 512M version, here.
  
  
• Here's the Lifehacker guide for beginners interested in trying this on their own.
  
  Note: the games for these consoles are very likely to be copyright material, so it's up to the reader's discretion on how to go about attaining them.
  
  
• Don't forget to check the other 8 pictures in the album that get cut off if you head to imgur from a browser, or you'll miss the best part (and the rest of the steps)!
  
  EDIT: Setting up the controllers seems to be the most common question asked in this thread. I personally went in via ssh (or F4 if you have a keyboard connected) to home/pi/RetroPie-Setup/RetroPie-Setup.sh to configure the RetroArch controllers. From there you can also find the button values which map to your controller, and add your advanced emulator functionality (quit game, save/load state, etc) to your /opt/retropie/configs/all/retroarch.cfg file like I did here. People looking for more help can find a more detailed thread (which sets up the controllers differently, mind you) at /r/raspberry_pi , here.
  
  New EDIT: If for some reason this button mapping doesnt work (perhaps for someone else that has another controller type, for example), I've heard that the retropie-setup.sh script has been broken with the newest RetroPie Images (2.3). What the setup script essentially does is call the retroarch joyconfig binaries and saves the output as your controller config . As a workaround, we can hardcode your retroarch.cfg file with your controller. Type the command:
  
  > sudo /opt/retropie/emulators/RetroArch/installdir/bin/retroarch-joyconfig -o /opt/retropie/configs/all/p1.cfg -p 1 -j 0
  
  and then follow the instructions that appear on screen. Afterwards use the command below to take that config file and append it to your retroarch.cfg file:
  
  >sudo cat /opt/retropie/configs/all/p1.cfg >> /opt/retropie/configs/all/retroarch.cfg
  
  You should now have the button mappings in retroarch.cfg to use for your advanced emulator functionality. Note, you'll want to do this for each controller you have (change '-p' and '-j' accordingly).
  
  Update (1/10): Looks like RetroPie v2.4 is out. The change log suggests that the controller config issues have been resolved (but I haven't tested it).

If the data you need to process is in your office's network you have two options:

• Let external access
  
• Keep a computer on in your office.
  
  
  The first one it's more complex and it has security risks, so I don't go there.
  
  
  About the first one, by computer I mean something it can hold a OS which let's you run Python and it has network interface. You can use a simple Windows computer, or even better, a vmware/virtualbox image of linux so you keep a clean environment.
  
  
  But my favourite solution would be to use a Raspberry Pi. Here I just link a RPi Zero from Amazon. You choose the one you want. Turn it on, put Linux, your code inside with crontab and connect with Wifi. For $30 and a day of work (if it's your first time) you will fix it.
  
  ---------------------------------- EDIT -------------------------------------
  
  Check this website to make local tunnels easily. In my opinion it keeps being an unnecessary security hole, and the one I'm sharing it cost $5/month. Search for alternatives if you want a free alternative.

Thanks! I'm using this display: https://www.amazon.com/gp/product/B076M399XX/ref=ppx_yo_dt_b_asin_title_o05_s00?ie=UTF8&psc=1

And a Raspberry Pi 3 B+, there are many bundles, I'm using a 32GB micro SD Card but a 16GB should be fine

To setup your Raspberry Pi I recommend this tutorial https://thisdavej.com/beginners-guide-to-installing-node-js-on-a-raspberry-pi/ (setting it up is really simple, but this link goes through a lot, like remote access and installing Node.js)

​

The Magic Mirror is also really simple, their official website is https://magicmirror.builders/, but this tutorial is really great, he shows how to setup your Calendar, Spotify, turn the screen, etc https://www.youtube.com/watch?v=HO326ptdlco

My son is the same age. Buy yourself a breadboard and some wires. My son loves moving the wires around in the breadboard, and it is a really cool fine motor skill activity. Plus, you can learn about making circuits together. Get a breadboard, some wires, a few LEDs, a few resistors, and a battery (a kit ) and you can play with that a lot.

And, there is a ton of learning to be done over years and years and years using this kind of stuff. When she's 4 or 5, you can start to build little Arduino based toys. Also, you can get really cool lighted push buttons and build some really cool simple circuits with that. Even something as simple as - "push the button, a LED comes on" is a lot of fun for a 17-month-old. Mine always wants to push buttons, and now they can have their own.

EDIT: word usage

This allows you to read and write to Memory cards via USB. A lot of old readers used the LPT port for doing this and they're becoming hard to find.

The main reason for making it was to use it in conjunction with MCLaunch which lets you place psx executables on a memory and run them directly. It's great for writing diagnostic tools, putting them on the card, and then running them on a system when it comes in. Pad tests, video testing, etc..

This is a cheap Nano v3 knockoff. A 3 pack runs $10. These have the bootoaders already burned and the USB chip works perfectly. The card needs 3.6v (you can use 5v, but it may shorten the life of the card) and the Nano clone is giving us 5v, so a voltage divider was created to drop it down. Cheap knockoff memory cards will need an external 7.6v supply. You can get this directly from a fat PS1 power supply.

This is running MemCARDuino.

If you have a system that isn't reading discs and if it's a later model without a parallel port, this is a great way to still run system diagnostics.

https://www.youtube.com/watch?v=w24Pq-EZVU0

Just a quick update. It appears these cheap Nano knockoffs are really, really good. I'm able to use third party memory cards without any problem. Also, the voltage divider doesn't seem to be needed either.

You've got a lot of good sources over in the UK. The pi-hut has a starter kit that looks to have good components included. Pimoroni has one with a keyboard & mouse as well as some blinkenlights and other goodies. Canakit is known for high-quality components. You can't go wrong with the official kit. I'm sure there are others. Just watch out for cheap power adapters and junk microSD cards.

If you want some electronic/hardware goodies, there are kits available as add-ons. Avoid the monster starter kits that include the RPi unless you're sure of the power adapter and microSD card quality. The separate parts bundles are a safer way to buy additional goodies.

In addition to that kit, you'll need the aforementioned keyboard, mouse and display. As for information, there's a lot available. The MagPi back issues are a good place to start. Look in the sidebar here for more info.

Start here!

It's super easy to build this project, and you could even splurge for a kit like this, or this to get you off the ground immediately...although these parts can be had for much cheaper.

Really, I can't recommend getting into this stuff enough. It's very affordable, very versatile, and super easy to get into.

That's an excellent little prototyping kit - perfect to get things started. With that he'll be able to figure out how to drive some good circuits. The original link is everything (including the Pi) to get the "other half" going :)

I see a related kit too which looks like a good adjunct to this pair at:

https://www.amazon.com/Freenove-Raspberry-Processing-Tutorials-Components/dp/B06W54L7B5

It's a little more advanced that particular one, but does have some cool displays and motors, as well as a DHT-11 temperature sensor.

I can't give you any recommendations, but I can give you some things to consider based off of my experience so far...


I bought a starter kit that came with a tiny booklet and various components off of Amazon. I feel like the kit could have done more. Take a look at the booklet on the previously referenced link. WYSIWYG for each project. I use the term "project" here loosely because it is more or less just copying what the picture shows and inserting the code (literally copy and paste). There isn't any explanation of why you connect things the way you do or even things to be careful of. Now, that being said, it at least gets you putting things together and gives a variety of components. So, take it for what it is worth.


If I were to start over, I would check out the official Arduino site and see what they have there. They might have the same type of things anyway and have the same pitfalls though. I don't know, I haven't purchased from them. It seems to me that many of the lessons are taught by example, which may not be the best method of teaching and from reading around, Arduino seems to just get things completely wrong at times (see comment by AndersJJ).


I was more interested in understanding what exactly is going on, but Arduino has a greater focus on putting you on the fast track to building something, which is great, but you should be aware of this.

This is the kit I originally ordered. https://www.amazon.com/gp/product/B01CUMNIV8/ref=oh_aui_detailpage_o03_s00?ie=UTF8&psc=1

There are other cheaper kits, and for NES emulation, the kit I bought is a bit overkill. But I sprang for a slightly more expensive kit because I'm also using the Raspberry Pi for other things besides just an emulation box.

Best thing to do is just shop around. At minimum, you want a kit that comes with heatsinks, power supply, and a sturdy case. If you don't already have spare HDMI cables and an SD card, you'll want those as well, of course.

You'll also want controllers like these for NES emulation: https://www.amazon.com/Controller-Laptop-approx-Windows-Kernel-Classic/dp/B01N2YT0QT/ref=sr_1_3?ie=UTF8&qid=1492532678&sr=8-3&keywords=usb+nes+controller

If you search for "USB NES controllers" on Amazon, you'll find a good many of them available. Shop around and read the reviews, although I imagine most are similar to one another.

>The Atomic Pi is available on Amazon US for US$34 and can be shipped worldwide

Ya but it's not

Also this implementation looks janky af, the power supply is on a separate board? No chassis of any kind available?

I'd be really interested in one of these if I could buy one with a basic little chassis and a power supply, but from the Digital Loggers site it seems like the best they have to offer is the unit itself with a separate power supply board so it accepts a 2.5mm power adapter which you appear to have to supply yourself. Why is the 2.5mm jack not on the board itself? Why can't I buy a compatible chassis and power adapter at the same time?

• Raspberry PI Starter Kit: £48.50
  
  
• HDMI cable: £0.70
  
  
• SNES USB controller x2: £12
  
  Total: £62.2.
  
  
  Also plays all other SNES games and all other games from the fifth generation downwards and other low-end PC games. Also doubles as a multimedia centre and full-desktop if you ever want to use it as something else. Also supports a wide range of enthusiast uses. A more constructive purchase as it goes towards a non-profit organisation dedicated to help enthusiast computing, rather than just filling up the pockets of a multi-billion dollar corporation.
  
  You've no point here.
  

I just helped a friend of mine build his own, it's very easy to put together yourself. Here's our component list, that you may find helpful.

Of course, there are many different cases and controllers you can use, you don't need to buy these specifically but it'll give you a good idea what you need to get started and what it will cost you when all is said and done. This is also assuming you just want something to play on TV. If you are a building a handheld, that's a different beast.

This is a pretty ambitious project with which to get into embedded systems.
Get an Arduino (or a clone, I've only bought the real deal). Get an Uno, a breadboard kit from Amazon (something like this).

You need to get a taste for what's doable, easy, or impossible. This will alter your design eventually.

I bought this kit on Amazon. I had it running in 30 mins. Super easy and pretty cool.

WS2018B
Is what I purchased originally. I may get different some that are just white/warm white since their for interiors of buildings and I'll have no need for RGB.

Down the road for sure I'd love to do a disco rave party in a big warehouse, random flickering fluorescent lamps and white/blue welding flashes. Endless possibilities for sure :)

So something like this on amazon? Would appreciate a recommendation if you have one.

Thanks again for the help!

It isn't a requirement but a commonly wanted item. You could do something like this or buy the Pi separate and get something smaller like this or this or maybe something with some direction like this as it comes with a project booklet?

I made my own toolbox for my work, since there wasn't really one out there. I know there is a library (different word, same thing essentially, right?) for what I do in python, but ultimately this is for fun.

I found a couple sensor kits that seem to have good documentation. Here is my amazon list if anyone could point out an obvious oversight. I have a monitor, keyboard, and mouse.

The "Freenove Ultimate Starter Kit for Rasperry Pi" and "Sunfounder Rasperry Pi 37 modules sensor kit v2.0"

Great project. You may like this pack of 100 Neopixel replacements though. They've always worked well for me and some have run them with 3.3 V instead of 5 V (results may vary).  

$16 for 100 vs $5 for 5 :)

A quick breakdown here


If you are looking for a kit for the raspberry pi, CanaKit sells them on amazon for a good price with everything you need



I order these by the dozen for work/projects They have everything you need to get going. But are lacking the parts needed to get into electrical projects



This has it all and it's on sale right now. Excellent price. Gives you the breadboard, GPIO-T, and ribbon cable. Everything you need to do your first few electronic experiments.


As for the Arduino, I can not give as much advice. I work primarily with Pi's You can do alot more with a Pi that does NOT involve electronics. but both are great platforms for learning.

It depends on what you want to do with it. If you’re a real beginner you could start learning python and could get one of those starter kits full of electronic components with tutorials. I’ve bought one of these kits and found them quite good. Their support is amazing too.

https://www.amazon.co.uk/Freenove-Raspberry-Processing-Tutorials-Components/dp/B06W54L7B5

Freenove.com

Amazon has the Canakit pi zero w basic starter kit for sale. It is the same price but with free prime shipping and free shipping on all orders over $25. Amazon

I'm using this now and it works very well: https://www.amazon.com/dp/B011TY0P9Q/ref=cm_sw_r_cp_apa_MHUUzbKF4RDYD

I've also used this: https://www.amazon.com/dp/B0722L338Q/ref=cm_sw_r_cp_apa_0IUUzbANYYJWV

My initial setup was a canakit with the included heat sinks, the heat sinks turned out to be a bit too high for the aluminium case and interfered with the fan installed in the inside. I switched to the acrylic case and the canakit heatsink didn't interfere with that fan.

If you don't have the canakit heat sinks, you're probably better with the aluminium case as it included a bigger fan than the acrylic case did.

I got the monitor a couple months ago, but just recently got the sound bar and wall mounted it today. Very pleased with the results and IMO it looks even better in person. The monitor now sits much closer to the wall and enhances the effects of the 140 LEDs compared to when it sat farther away on its stand. I'm able to control them with an arduino nano clone using the fastled and apa102 libraries along with a nice little program called Ambibox that does the screen capture and communicates with the arduino. I was a little concerned going into this that the nano wouldn't be able to refresh the LEDs fast enough since I had seen it mentioned from others with diy backlighting that the response times were not very good. Fortunately, this has not been the case and it works great in games, movies, and even while dragging a window around the border really fast it has no trouble keeping up.


Some parts I used for the backlighting:

LEDs- Mokungit 16.4ft 5m APA102-C Individually Addressable Magic Color LED Strip 60 Pixels/m 300 LEDs DC5V (Black PCB Non-waterproof IP20) https://www.amazon.com/dp/B01ABRSUQW/ref=cm_sw_r_cp_apap_kbn4zdRbbCiRv

Microcontroller - For Arduino Nano V3.0, Elegoo Nano board CH340/ATmega328P without USB cable, compatible with Arduino Nano V3.0 (Nano x 3 without cable) https://www.amazon.com/dp/B0713XK923/ref=cm_sw_r_cp_apap_9KrcrQG5Zdekd

Power supply - KNACRO AC 100-240V to DC 5V 10A 5V / 10A MAX 50W Power Supply Adapter Transformers Interface 5.5x2.5mm Suitable for Routers switches control systems 5v 10a https://www.amazon.com/dp/B01HEQH61I?ref=yo_pop_ma_swf

Edit: Here is a link to the sketch I'm using on the nano. This was originally written for use with ws2812b LEDs and I simply modified it to work with apa102's. You will want to change the following variable to match your setup:

define NUM_LEDS 140 (Number of LEDs you have total)

define DATA_PIN 11 (Can be different depending on which pin you want to wire it to)

define CLOCK_PIN 12 (Can be different depending on which pin you want to wire it to)

Edit 3: More pictures in this album

Well, a quick duckduckgo search found this in regards to that device: https://www.reddit.com/r/youshouldknow/comments/2c5qok

So I'm going to say I really wouldn't use that going forward with automation or security. Other than that, it doesn't look like something that can run Linux.

If you have a spare computer, you can get started with home Assistant on that. You can also go get a raspberry pi for $35, but if you feel you're going to need more power I'd recommend a PC.

I use the atomic Pi. $33, works much better than the Raspberry Pi 3, at least.
Atomic Pi - High Speed SBC with Peripheral ICs https://www.amazon.com/dp/B07N298F2B/ref=cm_sw_r_cp_apa_i_ftpJDb5C6ARHQ

here is a pretty good kit.

http://www.amazon.com/CanaKit-Raspberry-Complete-Starter-Adapter/dp/B00LVAFC7Y/ref=sr_1_3?s=pc&ie=UTF8&qid=1412291698&sr=1-3&keywords=raspberry+pi+b%2B

And here are a Ton of Projects from Lifehacker. :)

https://www.google.com/webhp?sourceid=chrome-instant&rlz=1C1SFXN_enUS598US598&ion=1&espv=2&ie=UTF-8#q=raspberry%20pi%20site%3Alifehacker.com

This is definitely the one I would recommend. It comes with tons of parts and tons of tutorials in the software. I love mine.

Honestly, I got the 8x8 matrix in an electronics beginner kit ( this one, highly recommend it if you want to experiment with controlling hardware wtih the RasPi) and it was the first thing that really sparked my interest. So I've been slowly learning how it works and brewing ideas of how to use it.

I'm kinda surprised that no one has said this yet...

If he's really into the IT thing, then the best present is a Raspberry Pi. https://www.amazon.com/Raspberry-Pi-Official-Desktop-Starter/dp/B01CI58722

I prefer ODroids, but if you don't have a dozen of these things, the best one to start with is the Raspi 3 kit above.

You may be able to get away with soldering an appropriately-valued capacitor across the button, with a discharge resistor.

When you first boot on, the capacitor allows current for a bit until it charges. After that, it won't produce a signal unless the car has been turned off for long enough for the capacitor to discharge.

It's a bit hacky, though, and depending on the timing of your circuit, along with the capacitor and resistor chosen may or may not work. Larger capacitance will mean longer charge time, IE, longer pulse. You can use an additional resistor in series with the capacitor to slow down the pulse, as well, but be careful, as this will also lower the peak output, potentially very drastically, depending on the value of resistor used.

Otherwise, I'd go with the suggestions of others here, favoring a micro-controller, since that is guaranteed to work with the right programming.

You can get like 3 arduino nanos for 14 bucks here:

https://www.amazon.com/ELEGOO-Arduino-ATmega328P-Without-Compatible/dp/B0713XK923/ref=sr_1_3?s=pc&ie=UTF8&qid=1549375027&sr=1-3&keywords=arduino+nano

It can be as little or as much as you want, to be honest.

I'd head over to /r/retropie and I guarantee you'll find guides that will work for you.

There are common kits on Amazon that have everything you need included like this one:
https://www.amazon.com/gp/product/B06XW6VX1H/ref=abs_brd_tag_dp

All you'd need is a controller and if you have a PS3 or other system, you can probably use what you have.

For kids that age, I would start with blinking LEDs, or maybe reading in from simple sensors, like photoresistors or thermometers. I had gotten a friend a beginner's arduino kit for about $30 and it came with a bunch of neat little pieces and enough to get started
Edit: Here's the kit: https://www.amazon.com/gp/aw/d/B016D5KUHS/
It does come with the Arduino also

Atomic Pi's run psp really well and are great for desktop computing and Plex as well.

https://www.amazon.com/Atomic-Pi-High-Speed-Peripheral/dp/B07N298F2B

/r/atomic_pi

I built one with a dmg01 and used a screen similar to this one - https://www.amazon.com/dp/B076M399XX/ref=cm_sw_r_other_apa_RPrIAbQM3H4FX

The HDMI was a bit overkill but there is zero lag compaired to the ones that run over gpio.

Honestly, if you are not running n64 or ps games, use a pi zero. Pi3 is way too big. I had to desolder all usb ports and Ethernet jack, what a nightmare.

As for the battery, get as much capacity as you can fit. For charging, the powerboost 1000c ( I think?) From adafruit works well for pi zero, wont quite cut it for pi3 though.

Well the good news is that they sell those ribbon cables in varying lengths (12", 24", 6.5ft) and they're relatively cheap. I switched over to a webcam several months ago which has a fairly long USB cable so it's a non-issue for me now.

My intention is to mount the camera to the 'ceiling' of the enclosure, near the front, looking down on the build plate. I only use the camera for monitoring my prints from a distance so that seems like a logical location. It's either that or on one of the corner legs just above the level of the build plate.

Anyway, my advice: A longer cable is cheaper than a replacement Raspberry Pi.

That should be the basic's of getting it up and running, you can always swap out Raspberry Pi case or other items, but that link is for everything all together. let me know if you have any other questions. Happy Modding!

Thank you a ton for your response, very helpful! I was wondering though, will the Power Supply that is included in this CanaKit work well enough to run 2-4 Controllers and with this case? Sorry once again, I'm new to this whole thing and haven't had much experience with stuff similar to this in the past.

Buy this: https://www.amazon.com/CanaKit-Raspberry-Complete-Starter-Kit/dp/B06XW6VX1H/ref=sr_1_2?s=pc&ie=UTF8&qid=1495634901&sr=1-2-spons&keywords=raspberry+pi+3&psc=1

Follow all the directions.

I dunno if you can still buy these, but I've had this since the early 2000's and it still holds up perfectly.

https://www.amazon.com/Kensington-Gravis-Gamepad-Pro-USB/dp/B00000K4TQ/ref=sr_1_4?s=electronics&ie=UTF8&qid=1495634935&sr=1-4&keywords=gravis+gamepad

https://retropie.org.uk/ - has all the files for retropie and setup guides you need. Setup took about an hour (including rom transfers)

Looks like this UCTRONICS 3.5 Inch HDMI TFT LCD Display - I've purchased a couple - work pretty nice. The pass-thru HDMI connection means it doesn't quite fit the "average" case design.

Yes, the Raspberry Pi can handle all of that, you should go with the Raspberry Pi 3 B, the newest model is not necessary. You can easily write a Python script to do all this, using the GPIO's for hardware interfacing, and some libraries for the text.
For the LEDs, you can use individually addressable LED's, which can all be controlled through one GPIO. You can control the humidifier with a relay (through GPIO), and there are some libraries like Jasper for speech to text.

There are tons of these kits way cheaper than that but without having to wait from China shipping.

https://www.amazon.com/kuman-Arduino-Raspberry-Projects-Tutorials/dp/B016D5L5KE/ref=sr_1_12?s=electronics&ie=UTF8&qid=1526091517&sr=1-12&keywords=raspberry+pi+kit

There are many others. They're a good way to introduce yourself to python and GPIO, for sure.

Your best bet is probably going to be an Atom (or even i3) SBC, running windows, instead of a Pi.

https://www.amazon.com/Atomic-Pi-High-Speed-Peripherals/dp/B07N298F2B/

this guy will run windows OK without much hassle (Don't try to put 10 on it, as of the last time i poked one. anyway. it runs fine, but drivers are a problem)

There are other x86 SBCs as well.

https://imgur.com/gallery/4kIDSpv

There's also a link to do it... in 75 easy steps (seriously) that's floating around. But I never bookmarked it because... 75 steps... But if that route that I linked doesn't work for you, maybe somebody will pull up that other link.

However you do it, you'll need 6 Dupont female to female (or with an arduino, 5 female to female and 1 male to female) jumper wires. Like these.

There's also a way you can use a cheap 1602 LCD like this as a status indicator for your Octoprint that will tell you % completed on a print and estimated time remaining. It takes 4 female to female Dupont jumpers. So you can reuse some of those jumper wires.

FWIW, if you live near a Microcenter, you can buy an arduino uno for $8... if the Raspberry Pi bootloader doesn't work for you. I tried it once and it didn't work right off the bat, but I had an arduino uno on hand so didn't try a second time.

Yes I am as well.

Well, there's Conrad, Reichelt, Pollin and such, and of course Amazon and ebay.

There's no real alternative price-wise. I order a lot at Aliexpress and similar sites for school workshops. :-) It takes 2-6 weeks, but it's really great if you are in no hurry. And it's not like most of the parts are any different than what the electronic stores here offer.

At Amazon you can find the Sunfounder and similar kits, but these are basically the same "no name" stuff.

It really depends on what parts you need and what are you willing to spend. In general, you pay three to ten times as much for some of the modules.

5x pi owner here! I buy Vilros kits like this one:

https://www.amazon.com/Vilros-Raspberry-Complete-Starter-Clear/dp/B01CUMNIV8/ref=sr_1_1?ie=UTF8&qid=1484015645&sr=8-1&keywords=vilros

Pi3, case, heatsink, power adapter, and hdmi cable for cheaper than all of those parts seperately. I don't usually need the hdmi cable but it's basically free at this point.

At some point you may want to invest in an electronics starter kit. I didn't have my first Pi very long before I really started wanting to hook things up to the GPIO pins. I bought this one and it was a great way to get started without spending too much. http://www.amazon.com/gp/product/B00CXMMDZI?keywords=Sunfounder%20electronics%20kit&qid=1457842854&ref_=sr_1_6&sr=8-6
Even though it says its for arduino all of it would work fine with a Pi

I use OctoPi and it works great.

Raspberry Pi 3

Power Supply

SD Card

[Optional] Camera

[Optional] Color touchscreen for TouchUI

Those screens are low resolution anyway. They're fine if you're just playing videogames, but even then they're just really low quality. There are good $25 5V screens with double that resolution that I'd highly recommend you use instead.


You can get them even cheaper on Aliexpress. I paid $20 for one, shipped.

I think you're back to Amazon:

https://www.amazon.com/CanaKit-Raspberry-Wireless-Official-Supply/dp/B071L2ZQZX/ref=sr_1_3?s=electronics&ie=UTF8&qid=1505496192&sr=1-3&keywords=raspberry+pi+zero+w

$24.99 w/ case & power supply. Same day shipping if you add $10.01 to your order.

Have it shipped to one of the amazon lockers, or to your friend.

I will give you my top 5.

1.The hard yellow springs $5 and you will have extras. These will help your bed stay level longer. I think I need to check mine once every.. 10 prints or so or every other week, maybe longer. https://www.amazon.com/dp/B013G5I4US/ref=cm_sw_r_cp_apa_i_vkE6Cb8SHNBVG

2.Glass bed. Lowes for $3 cut 2.5mm. Ender 3 bed known to be warped.

3.Pick up a Raspberry pi ~$50 and install octopi/ octoprint.. free, and a mini b to USB cable $5. Now you don't need the to fiddle with micro SD and can manage everything from PC. https://www.amazon.com/dp/B07BC6WH7V/ref=cm_sw_r_cp_apa_i_olE6Cb8J91Q1J

And
https://www.amazon.com/dp/B00P0GI68M/ref=cm_sw_r_cp_apa_i_umE6CbPGSR7T4

4.Raspberry pi cam $25 and longer cable $3 to go with your Raspberry pi octoprint. Now you can monitor prints while "away" .. aka relaxing in your lazy boy watching YouTube vids on how bad season 8 of GOT was. https://www.amazon.com/dp/B01ER2SKFS/ref=cm_sw_r_cp_apa_i_noE6CbXTHCPDS

And
https://www.amazon.com/dp/B00M4DAQH8/ref=cm_sw_r_cp_apa_i_ipE6Cb9RK6QNR


5.Bowden tube $11. Only if you plan on printing hotter then 240c. So petg, abs.. ECT ECT . https://www.amazon.com/dp/B079P92HN9/ref=cm_sw_r_cp_apa_i_KjE6CbDMX6SGE

My VMs, configs, and files are backed up to a HDD I keep offline. I'm thinking about adding a NAS into the mix for somewhere around 200-400 dollars. Low energy consumption preferably if anyone had any recommendations. :)

Nah, this one looks fine, though. You just want one that comes with a board and some components to play with. Also the book a Beginners Guide to Arduino is nice.

I have had a lot of fun with this set for the Arduino for $30.
I play around with both the Arduino and ESP8266 as well as the Pi. I think they all use 3.3 volts, same as the Pi, so there shouldn't be any voltage shifting needed. The only problem is you won't have the Pi tutorial, which can be found elsewhere.

Edit: A quick search found these two kits with Pi tutorials.
https://www.amazon.com/kuman-Arduino-Raspberry-Projects-Tutorials/dp/B016D5L5KE/ref=sr_1_1_sspa
https://www.amazon.com/kuman-modules-Sensor-Raspberry-components/dp/B01EURJ7XY/ref=sr_1_2_sspa

Here are 2 possibilities in how you could achieve this goal.

1 There's a version of Celeste available for the Pico-8 which is available on the Raspberry pi. You have to pay $15 for the Pico-8 on top of the price of the Raspberry Pi and the Pico-8 version of Celeste is obviously going to be more limited than the full desktop version is.

The biggest pros of using this method are that you'll be able to make a lighter weight handheld that doesn't use up nearly as much battery life as the other option I can think of. Pico-8 Celeste can be found here

2 You could get an Atomic Pi which is a $40 SBC that has an X86 CPU, meaning it's capable of running Windows and x86 linux distros, which would both be able to run the full desktop version of Celeste.

The biggest issue with this is that this would most likely be more expensive than the previous option and would require a much beefier battery in order to get a decent amount of game-time on it.

I hope this helps!

I use this one, it is very well made and keeps very cool https://www.amazon.com/Eleduino-Raspberry-Aluminum-Enclosure-Heatsinks/dp/B0722L338Q/

I do this type of thing on most of my guitars and use Dupont jumper wires. I cut the connectors off leaving a short bit of wire that I solder directly to the pickup wires and the various pots and switches. Makes for super fast pickup changing as well as coil splitting, series/parallel, pot swaps, etc.

I use these for attaching the output jack on my strat to the pickguard. This allows quick removal of the entire pickguard.

Case

There are a couple adapter boards for the Pi so you can use Arduino shields. Like this one http://www.robotshop.com/en/arduino-adapter-raspberry-pi.html?gclid=Cj0KEQiAnb3DBRCX2ZnSnMyO9dIBEiQAOcXYH9ZFIdE01cTWcUiCQ6euOGNJcwSwUuN88JkXhTGbLRcaAiF88P8HAQ

As far as sensors or electronics they you could connect to either Arduino or Pi, just pick up a kit from amazon and connect them with a breadboard. Example, https://www.amazon.com/gp/aw/d/B016D5L5KE/ref=mp_s_a_1_1?ie=UTF8&qid=1483758239&sr=8-1&pi=AC_SX236_SY340_FMwebp_QL65&keywords=raspberry+pi+sensor+kit&dpPl=1&dpID=61YQ5YabPgL&ref=plSrch

Tldr at the end

I can't find any schematics for the cable so I'm not 100% sure it would work, but judging by some size comparisons, I think you could use some jumper cables meant for breadboards. If you could give me the size of the port of an individual pin of the 8 pin connector I can verify.

If the size is 2.54mm then for around $6 you can get: Multicolored Breadboard Dupont Jumper Wires - ALLUS J7011 120Pcs 3in1 Ribbon Cables Kit, Male to Male (M/M), Female to Female (F/F), Male to Female (M/F) for Arduino and Raspberry Pi https://www.amazon.com/dp/B073X7P6N2/ref=cm_sw_r_cp_apa_i_oseBDb0RSX6HQ.

You can get a 10 foot 1/4 TRS for ~$6 on Amazon: Hosa CSS-110 1/4" TRS to 1/4" TRS Balanced Interconnect Cable, 10 Feet https://www.amazon.com/dp/B000068NYH/ref=cm_sw_r_cp_apa_i_7ueBDb0M84YBM.

You're looking at about $7 for the xlr: AmazonBasics XLR Male to Female Microphone Cable - 6 Feet, Black https://www.amazon.com/dp/B01JNLTTKS/ref=cm_sw_r_cp_apa_i_0weBDbQNK67CW

If you have a trs cable, jumper cables, or an xlr cable at your house it will be cheaper. You would also need a soldering iron and some solder ~$10-$15.

It depends on the supplies you need. Assuming you don't have the cables but you have the soldering iron you're looking at about $20. Otherwise it is the same price.

Tldr; it's only $10 cheaper if you don't have a spare xlr, 1/4 TRS, or jumper cables. If you don't have any of the cables as well as the soldering iron, it's the same price.

Coucou le FL,

Je suis néophyte total, mais j'aimerais monter un petit serveur plex avec un Raspberry Pi 3 B, branché à un disque dur externe autoalimenté. De ce que j'ai compris, c'est assez facile, avec un OS spécial clé en main à copier sur la carte SD, mais je suis preneur de retours ! Plus généralement, vous pensez que c'est une bonne solution pour un serveur Plex ?

Des bisous !

Yes it is. There are multiple sellers.
You can buy it from AmeriDroid or from Amazon.
https://ameridroid.com/products/atomic-pi
https://www.amazon.com/Atomic-Pi-High-Speed-Peripheral/dp/B07N298F2B
Or here from Digital Loggers
https://dlidirect.com/products/atomic-pi

You could hook up a clap sensor, heat sensor or any of the other hundreds out there to have a way for the students to interact with the Pi.

Here is the sensor pack I bought my girlfriend a couple months ago:

https://www.amazon.com/gp/aw/d/B016D5L5KE/ref=mp_s_a_1_3?ie=UTF8&qid=1512001434&sr=8-3&pi=AC_SX236_SY340_QL65&keywords=sensor+raspberry+pi+3&dpPl=1&dpID=61DwG7Sj1NL&ref=plSrch

And an instructable to build a clap on light:

http://www.instructables.com/id/Using-a-sound-sensor-with-a-Raspberry-Pi-to-contro/

You should be able to find some prebuilt solutions for the clap sensor on github.com

If you're interested I'll crack open my laptop and look for a prebuilt project.

$25. Came with a case, tv ribbon cable and a power cord

It's a Canakit one: https://www.amazon.com/dp/B071L2ZQZX/ref=cm_sw_r_cp_api_QxtNzbQJE47JD

Although now I want a RP3 because I'm feeling like a MBPr2k16 owner here because I need a dongle or adapter to really do anything.

I'll just configure it over a terminal on the SD card

Good work! I just had 300 Neopixel clones arrive and I'm gearing up to build a 16x16 GameFrame clone.

Like most others here, I'll recommend making a RetroPie. I made one this last x-mas season for my niece, and had no previous experience working with Raspberry Pi; just followed a guide on youtube like this one. Alternatively, you can buy a kit with RetroPie pre-installed. The video I linked to can show you how to put roms onto the pre-setup RetroPie.

Thank you for the reply !!! Is this what you are referring to https://www.amazon.com/CanaKit-Raspberry-Starter-Premium-Black/dp/B07BCC8PK7/ref=mp_s_a_1_1_sspa?keywords=raspberry+pi&qid=1556851287&s=gateway&sr=8-1-spons&psc=1 ?

This is really the best/easiest option.

RaspberryPi 3 ($43) + Raspberry Pi Camera (~$20) + 2ft ribbon cable ($7) = $70

OctoPi (Free)

One writeup: http://3dprinterwiki.info/wiki/wanhao-duplicator-i3/computer-software/octoprint-on-raspberry-pi/

A cheaper option is to buy a cheapo wifi camera that works with iPhone. (~$20) Connect your printer to your PC and use something like TeamViewer to remote from your phone to your PC to control the printer. It's a multi-step solution but cheaper than RaspberryPi.

Well here is some other stuff to add to your list to check out:
Clone board for the nano. It's what I am using for my buzzer instead of the uno. Does the same job.

[Wifi modules] (https://www.amazon.com/gp/product/B00O9O868G/ref=od_aui_detailpages00?ie=UTF8&psc=1)
Haven't messed with these yet, but for that price, i just bought em.

Bluetooth module Same deal, haven't messed with it yet.

Thank you Jeff, I’m buying my first Pi Tomorrow. Does this Amazon Canakit Pi look decently priced? What else would I need? (https://www.amazon.com/dp/B07BCC8PK7/ref=cm_sw_r_cp_api_UWTXAbXG895A8)

Well shit I'm sorry, weren't they just $10 last month? So I actually have one on the way, I got the kit with the camera case, a little heatsink and power supply for $22. I could have sworn before I added this to my wish list about a month ago that a bear Raspberry Pi zero W was only $10.

This is what I ordered: CanaKit Raspberry Pi Zero W (Wireless) with Official Case and Power Supply https://www.amazon.com/dp/B071L2ZQZX/ref=cm_sw_r_cp_apa_wtIKAbZ14RZ51

The $10 raspberry pi zero (w?) From my memory was $10 for the bare board without a case. I opted for the one that included the case because I'm going to use it as a security camera for my front door.

Vilros Raspberry Pi 3 Complete Starter Kit with Clear Case and 32GB SD Card https://www.amazon.com/dp/B01CUMNIV8/ref=cm_sw_r_cp_apa_0CD6xb9RDCS5Z

Atomic Pi - High Speed SBC with Peripherals https://www.amazon.com/dp/B07N298F2B/ref=cm_sw_r_cp_apa_i_QYG3Cb0T1QZBH

It was 35 bucks like several weeks ago.

I'm super inexperinced, but an arduino could do this easily. That might be too large for you application. You might need a micro controller component, but I've never used one.

I have an arduino uno (clone), beginners kit, that has been really educational. https://www.amazon.com/gp/product/B016D5KUHS/ref=oh_aui_detailpage_o05_s00?ie=UTF8&psc=1

Yep, just get another cable.

I used this but it's not In Stock right now. The atomic pi is $27 on Amazon right now. You will need to pick a 12v or 5v power supply to match whichever daughter board you pick.

Edit: I found this combo which includes the daughter board and power supply for $39.99

Then you probably do need the USB driver for the board. This Amazon listing for Kuman Uno has a video at the bottom from a buyer named Mikey who says, "Took me about 5 minutes to setup the drivers for the clone board." I would watch that video, and if it doesn't say where he got the drivers ask him on his YouTube page.

They are on Amazon now, just hurry. Atomic Pi - High Speed SBC with Peripherals https://www.amazon.com/dp/B07N298F2B/ref=cm_sw_r_cp_apa_i_iyA2Cb7WR2BT0

In Canada, here's the kit I picked up off Amazon:

CanaKit Raspberry Pi 3 B+ (B Plus) Starter Kit (32 GB EVO+ Edition, Premium Black Case) https://www.amazon.ca/dp/B07BCC8PK7/ref=cm_sw_r_cp_apap_kkAqsSvlhTafy

There are videos on YouTube that show you how to assemble, and the kit itself comes with decent enough instructions. The kit includes

• motherboard
  
  
• heat sinks
  
  
• enclosure and power cord
  
  
• SD card
  
  
• power switch (this seemed unnecessary)
  
  
• HDMI cable
  
  

There is a kit for 89$ on amazon. comes with board, case, power supply, 32g sd loaded with retropie, and 2 snes style controllers.

I just bought this one off of Amazon today. Comes with everything you need to get started (minus a monitor, hdmi cable, mouse, keyboard).

I just wandered into a local shop and got the official Raspberry Pi 3 kit with SD included: https://www.amazon.com/Raspberry-Pi-Official-Desktop-Starter/dp/B01CI58722/. If all you want to do is use it for staking, after it is set up all you need to have plugged in is a power supply (and network cable if you have no wireless). The SD was 16GB and I wouldnt go smaller than that. The kits that are being sold with heatsink - you shouldn't need that - staking doesn't require much CPU. If you want to use the Pi for other things at the same time then maybe. Also, You can easily install XRDP with a single command if you want to have a remote desktop capability, but the NAV wallet is just a web interface and it has a menu option to restart the machine if required.

I have got this one for my graduation work. I work on it since one year. Never had any problems. Maybe its a bit expensive, but you have everything to start and a Case!

and this [kuman!] (https://www.amazon.com/Kuman-Complete-Tutorial-Components-breadboard/dp/B016D5KUHS/ref=sr_1_1?ie=UTF8&qid=1486695798&sr=8-1&keywords=arduino+uno+starter+kit+kuman)

I've started with the CanaKit 3 model B (not plus) and just built my setup from there (formatted SD card, downloaded, flashed, and configured RetroPie, then transfer the ROMs). It has everything you'll need minus controllers (you'll have to provide those yourself)

This is the kit that I found that has the basics. https://www.amazon.com/CanaKit-Raspberry-Starter-Premium-Black/dp/B07BCC8PK7/ref=mp_s_a_1_2?ie=UTF8&qid=1540165862&sr=8-2&pi=AC_SX236_SY340_QL65&keywords=canakit&dpPl=1&dpID=51QERaUXmBL&ref=plSrch

https://www.amazon.com/dp/B07BCC8PK7/ref=cm_sw_r_cp_api_PTy9BbDD7NWB1
This is the full package

The thing with the heatsink is an atomic pi. It's a SBC that has an intel atom x5 and 2gb of ram. It can run win10 but I have lubuntu installed.

https://www.amazon.com/Atomic-Pi-High-Speed-Peripherals/dp/B07N298F2B

You could look at getting an Atomic Pi.

Do note that it's a little more involved than just a raspberry pi, especially when it comes to powering.

These are x86 Pis (Atomic Pis): https://www.amazon.com/Atomic-Pi-High-Speed-Peripheral/dp/B07N298F2B

It's part of the package.

How tech savvy are you? This could be done with a raspberry pi and rpi camera for about $60. You would need to make a waterproof case yourself. And you would need to script the pattern you wanted.

I too am just starting. I did buy the Raspberry Pi and a starter kit though. Here's what I picked up:

and

Freenove Ultimate Starter Kit for Raspberry Pi | Beginner Learning | Model 3B+ 3B 2B 1B+ 1A+ Zero W | Python, C, Java, Processing | 57 Projects, 401 Pages Detailed Tutorials, 220+ Components

They seemed reasonably priced and the Frenove kit has enough parts to jump in. There is also a link in the Freenove page to some starter info and tutorials.

Now I just need to sit down and start using this.

I'm an EE and It sounds like you need arduino in your life. You can get a starter kit that comes with an Uno, wires, buttons, leds, pots, 7-seg displays and all kinds of other crap for $20-$30.

Here's the starter kit we had to buy for Embedded Systems II "Kuman Project Complete Starter Kit with Tutorial and Reliable Components for Arduino UNO R3 Mega 2560 Robot Nano breadboard Kits https://www.amazon.com/dp/B016D5KUHS/ref=cm_sw_r_cp_api_MYFizbGBA88CX "

Has anyone bought the hax mods to try. I might buy some tonight just to fiddle with it and see how easy it is to modify to be broken

edit: these are the ones I bought

Get a 3 B+ kit with everything you need (aside from the keyboard, mouse & screen) for $80: https://www.amazon.com/dp/B07BCC8PK7/ref=psdc_3015426011_t1_B07BC6WH7V

No soldering required and you can be up & running in <5 mins.

I noticed no one else suggested that. A model 3b+ kit is about $80 --this one comes with a power switch and a 32GB card-- then add a cheapo 1366x768 or 1080p monitor, with a cheap Logitech mouse/keyboard combo. All of that should be around $200.

Dumb RGB LEDs are cheap but need a lot of wiring (1 per colour + ground).

Ideally, if you're planning on making an array use neopixels (WS2812 is the controller in them). They then have a single data pin and then vcc/gnd. You can get them premade into strips, squares, rings, etc or as individual PCBs, throughholes, or simply the WS2812 cell itself (which are tiny and hard to solder).

Typically to wire up 2812s to an arduino you need to put the Vcc/GND in parallel with the Arduino (microcontroller) and a beefy capacitor (at least 100uF or more) on there in parallel too.

Then a single data pin from the mcu goes to the first ws2812. Typically with prefabed boards/rings/etc they'll have a Din and Dout pads (along with possibly a 2nd set of Vcc/GND) so you just chain the data/vcc/gnd pins.

edit: To answer your actual question at the end yes you can use say common cathode drivers but then 3 pins for R/G/B and then cycle through them quick enough to avoid flicker. This will be very messy to wire up though. WS2812 strips/arrays/etc are handy. For instance this is a 10x10 array of PCB'ed individual WS2812 LEDs. You snap them off and then solder up the vcc/gnd/data pins in a chain to make designs. Alternatively, this is a 4x4 PCB that can also be chained.

Hahahaha!!!!.... Fake Satoshi... He's so funny.

I'm running a Full Validating Node on a $70 computer. With the new "prune" setting, you don't even need an external hard drive. It will all run (the OS, and the node software and data) on a 32GB microSD card.

You can buy one here.

You can see it running here, pulling 1 watt which costs me about 15 cents worth of electricity a month.

It currently has connections to 17 nodes.
