Reddit mentions of microtivity IB401 400-point Experiment Breadboard w/Jumper Wires

• 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.

two words...

Breadboard



Ok maybe that was just one word...

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 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.
  

I just ordered components to make my first box mod, but have done small electrical work before.

Helping Hands will make your life much easier, may not be necessary if you only intend to make one mod.

a decent digital multimeter is required, as is a Soldering iron.

A Breadboard is very useful to ensure everything works as it should, before you have it all finished and put in the case.

those are all I can think of right now, sure there are others people use regularly though

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.
