creating a pulsating LED to increase current but keep heat down.

Im looking for a project, that i can create myself. using a 555 timer to create a low duty cycle TTL square wave to power an array of Inferred LEDS at a very high current for short segments of time.

basically i want to get really high outputs from an led and keep it from frying itself but turning it on and off really really fast to keep the heat down. Posted in: #Coffee Room
