Elecrow Christmas Tree

Elecrow sponsored (or maybe still sponsors (probably not) or maybe will sponsor again next christmas (yep)) a free PCB prototyping service (10 cm x 10 cm) for christmas related designs. So I designed and routed some shiny battery driven christmas tree.

It is just a simple circuit with some LEDs around an Atmel ATMEGA328P with the possibility to measure battery voltage. All LED currents are planned to be very low so all LEDs will be driven by the microcontroller itself. In the download section you will find the schematic, all gerber files and the sourcecode.

Update: Elecrow published a blog post referencing my design.
