Homemade Electronics

by Rich on February 15, 2010

I’ve been interested in microcontrollers for a long time. They’re small and cheap, they’re extremely customizable, and if you want to make a piece of electronics do something, they give you a balance between complete efficiency and flexibility. There are a lot of places where it’s likely possible to solve a problem using only passive components, but a microcontroller essentially lets you solve it by explaining what you want (i.e. programming it). Sounds just about perfect to me.

I have a handful of projects I’m kicking around. Some are more curiosities, some have a little more substance to them. The more substantial projects tend to feed other hobbies.

My planned projects, in no particular order, are:

Persistence of Vision (POV) based display

Automated pickup winder

Morse code keyer, and a decoder if I feel fancy

Various CNC projects: small soft materials/PCB router, larger project/wood router, laser engraving

Should keep me busy for a while
