Why build badges in a year, when you can do it in three days? Let's get analog, baby! Since the theme is 1983: On the Edge of Dystopia... I've got a plan for a one-off wearable, and some easy ones to spread the love.
It came out of an ancient video camera, where it served as the viewfinder. Long ago I had built it into a mini monitor, now it's being dis-mantled and re-mantled.
Here we have an old cctv camera gutted and hooked to the CRT. The ATtiny13 is pulsing some mystery signal into the video line...
Code for some morse code blinkin' was completed last night. You can find it on github. Got an ATtiny13 set up to be programmed by an Arduino Uno - which was much faster and easier than I thought, and to be honest quicker than dusting off my Atmel tooling.
