Me and my wife recently had our first child. I’ve been trying to come up with some projects I can do for the kid. Well, around this time of the year the fireflies go crazy around my house, so we came up with the idea to do led fireflies in a jar. It should be something cool for him to stare at and is easy to build.
Schematics, C source code and hex file are available here on our wiki. If you want to build one it should only take about an hour.
I’m planning on making a version 2 with some changes, stay tuned for that one.
