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 →

Announcing a new Quick Video: Gates

Here's the thing. I started with NPN transistors because my intent is not to start with some sort of weird theoretical "see these diagrams, that's why it works" nonsense. I think one thing that is sorely missing from computer science is the hands-on part: the part where you actually touch something tangible and see it... Continue Reading →
