Extinguishable LED Candles

We love Blinkies. Especially simple led throwies.

Lately, we've been playing with "candle flicker" LEDs, which contain a tiny chip that makes their warm light flicker like a flame.

Tape 'em to a battery and watch glow. They're great. But we wanted a version we could, essentially, blow out.

Enter the tilt switch.

This little component is a small cylinder, about the size of a bean, with a metal ball inside. When the cylinder is vertical, the ball rests on two metal leads at the bottom, completing a circuit. Tip it, and the ball rolls away, breaking the circuit.

So we combined tilt switches, flicker LEDs, coin batteries and some plastic battery holders to make 15 little candles.
