This circuit has been designed to provide a clearly visible light, formed by 13 high efficiency flashing LEDs arranged in a pseudo-rotating order. [more]
It lights Ultra-Bright LEDs in a sequence and each LED flashes brightly very briefly. [more]

The idea is not new and I hear a similar circuit was developed about 40 years ago using germanium transistors. The idea is to connect the lights so that as one turns off it causes... [more]
