Icy Single Malt Scotch
LED panel (I took from a outdoor light)
Voltage booster with wires
Solder the LED to the voltage booster and the booster to the Peltier tile,........place the hot side of the tile down and place your favorite cold beverage on the cold side! Boom,....free-ish light!
the voltage prior to the booster is about 100mv, with the booster close to .5v,....enough to power any simple led. straw led work also,...shouldn't pay more than 1 dollar for light, 4 dollars for the tile (or remove from old mini fridge), booster may cost 20 dollars.
