In my attempt to make glowing cake, I've purchased edible silver glaze that's normally used to color fondant to paint "wires" on baked goods. This video shows my impromptu collaboration with Chris (narrator) at Noisebridge, in which we coated a Madeleine cookie with some silver glaze and used the glaze as wires to link an LED in the cookie to wires from the power source. We used 15.26 V, 40 mA current limit from a power supply to drive the LED, so there's more work to be done on lowering the power. The arduino circuit board controls the blinking property of the LED. Later in the afternoon, we swapped the LED for a surface mount LED that's super bright and photographed well under the Sunday sunshine. Photographs are here: http://bunnymeetsbean.blogspot.com/2009/07/light-up-pastries-with-led-and-edi...

  • The LED providing the light serves the same function as a candle, so no, it doesn't contaminate the madeleine. We washed the LED off beforehand, and it has no solder (which often contains lead) deposited on its legs.
