Inspiration

The PCB on the badge didn't do anything, which was incredibly boring

What it does

It blinks the lights on and off

How I built it

I looked up a design for a bistable multivibrator, made one on a breadboard and once sure of the design transferred it to the pcb by cutting traces, adding wire links and messily stuffing component legs into the holes

Challenges I ran into

Some pads which looked joined where not joined, some parts were not initially soldered in the correct place and there was a mysterious short circuit somewhere

Accomplishments that I'm proud of

I now have a badger that does something slightly less boring

What I learned

The badges were really not designed for this

What's next for Blinking Badge

A large array of boards that can combine to form a computer that can run doom
