This is a re-engineering of the wonderful ​BlinkyPOV We created our own because we prefer AVR microcontrollers to the PIC they used, but otherwise it is a brilliant design.

First prototypes back. There are some issues:

• The Kicad LED footprints dont have a bottom soldermask opening (or it is way too small)
• The ISP pins should not be connected to LEDS

Tools Etc

• ​KiCAD
• ​OSH Park
• ​DigiKey Corporation

Firmware Notes

There is no UART. Have to bit-bang one if needed.

With default settings, ADC converts at ~15kHz as advertized (66 uS per conversion)
