Remember that Pi Candle I made a month ago?
I was doing a quick scan of the Makezine website, and I discovered an LED assortment with built in chips that make them flicker when DC power is applied! If I made my candle with one of these special candle flickering LEDs, then I wouldn’t need to connect it to the Raspberry Pi or Arduino. I could just power it off of a battery!
