*UPDATE - 4 May 2014
None of my hypothesis in this video were correct nor should you take any advice I give in this video. Please watch my more recent videos for correct information about crystal cells.
In this video I talk about different designs of crystal cells & their output values. I connect two of my crystal cells up to a joule thief circuit & to a small motor to show they do work. Future videos will be about tweaking the crystal cell to increase current output & mAh.
