Disclaimer: This was the very first project I made and was built before I knew how to design PCBs. Wires. Wires everywhere.

It's a basic LED chaser. Here's the schematic I based it off of: http://tinyurl.com/ohbmxxw (I skipped the pot.)

I think it came together fairly well, except that the box was too shallow. It won't close all the way with the 9 V battery included.

A demo video is linked to the left.

Electronics from Digikey. Enclosure, paint, and feet from Michaels.
