Joule Thief Power Box
This little JT surplus flash circuit power box was supposed to be in my earlier video but most of those segments got dropped out somehow. Anyway, running off an AA battery in a handy box that you can plug many things into. (Only devices that will run from high voltage/high frequency) You can plug test leads into it to test different led bulbs to see how well they light before building the entire circuit. More information over at overunity.com.
Thanks for watching.
