ZappWe're still waiting on our prototypes. In the meantime we broke out the voltage regulators and some PCBs we ran through OSH Park several months ago for them. Unfortunately we misread the datasheet and ran the traces incorrectly. Magic smoke came from two of the regulators before we worked out all the issues. But now the "badge" is happily running off of 4 AA batteries without being tethered to a USB-Serial adapter.
Below is a video of the "badge" running our matrix animation with 4 LEDs.
