My 100 Watt LED Flashlight

CSEE Alum Charles Lohr demos his DYI mega LED Flashlight

About two years ago, my friend Will purchased a 100W LED from ebay with a plug-in power adapter. I thought I could do better, so I got a bunch of 18650 ultrafire lithium ion batteries, hooked them in series and made a buck mode power supply using an AVR to control it.
