Making Circuit Boards.

So one of my goals of my series "Introduction To Digital Computers" is to show the design of a computer that can be built entirely out of NPN transistors. The idea is that by showing the design of a digital computer from the absolute ground up--from something you can hold in your hands rather than... Continue Reading →

Gear Tooth Geometry.

I feel like, with making the first two "Introduction to Digital Computers" videos I've gained a superpower. And I've used that power to help me visualize and solve another problem I was having, figuring out the shape of spur gears (and eventually, internal spur gears, the next major feature I'd like to add to the...

Wire forms.

So if you've been watching my Quick Videos you know I've been building a lot of circuits on prototype boards. I also took the liberty of 3D printing a couple of useful tools to help measure and bend wire. The first on the left helps measure lengths of wire; each wire is measured in each...
