Showing the weather.

So here's a quick little Arduino project which combines an Ethernet shield, a display shield and an Arduino-compatible Adafruit Metro to display the current weather and forecast. The goal of this project was to pull weather data from a remote server (in this case, the DarkSky API) to display the current temperature, weather and a... Continue Reading →

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...
