Intro: Future Xmas Lights
Imagine if you will the lights at 90 degrees and a whole string of lights instead of just one led becoming lit at a time. A jewish friend call it a binary xmas menorah. Should of added music maybe later. Still have to build the interface for the battery operated lights. I will document that later. In the mean time check out: https://www.instructables.com/id/No-solder-parallel-port-break-out/
Update: bought all the battery operated lights, relays, and the other parts. did a non-solder mockup and it works. Time to do some soldering.
