I made grandma's old and rusty teapot warmer a BPI case It offers also additional space for two harddisks.
Instead of a candle I attached 24 LEDs and let them pulse softly and randomly. Maybe the heat sink can keep my tea warm, too.
Next step would be to let the light show be controlled by music through the built in mic. Anybody knows how to access the mic input of the BPI-M3 with C/C++?
