3 Ultrabright Leds Powered By Joule Thief Ferrite Bead Circuit
This is a video of 3 LEDs (2-265000 MCD and 1-26500 MCD 10 mm Ultra brights)running from a single AA battery. Each LED requires between 4 and 4.5 vdc and over 100 mA’s each to light. For more info, see overunitydotcom in the Joule thief topic. This is just documentation of my beginning experiments, these little circuits have done more, much more and I will be posting more videos.
