Tiny Lipo Batteries

A project log for Electronic Dice

A set of smart dice, the same size as traditional ones, full of LEDs and Bluetooth-enabled.

Following a suggestion from a commenter on youtube, I was able to find a lipo battery small enough to fit in the dice! I received samples early this week, very exciting!

I got so excited to start seeing if I could make the next version only 16mm wide that I started working on the schematics and now 3D CAD. That's just as well, since now I can get prototype boards made while I continue to work on the firmware.

Oh and I'm going to try and integrate wireless charging! Not only is it really cool, it'll allow me to never have to open the case (assuming I get over-the-air programming to work), in turn meaning I'll be able to just pot everything down and glue the case shut (no more screws).

I'm trying to stream my work as much as possible. So don't hesitate to follow me so you get notified! http://twitch.tv/jean_simonet/
