My prototype digital candle looked really good. The prototype used a separate power board wired to the Teensy3.0. That was cost effective but cost a lot of labor and delicate soldering to complete. This new board swallows the Teensy and incorporates the power supply. Better still it has a slot to swallow an XBee. That means this board will be able to communicate with the outside world. I'm not sure what I'm going to do with that just yet. I'll think of something.
