How bright could I get the blade with adjustable resisters on each of the four diodes? I searched the forums and I did not find anyone that had done this with the Petit Crouton. If there is one forgive me. First off is this even possible? What kind of batteries should I use to do this? I got just under 8 inches with a 1 inch ID in the saber I designed using MHS parts and copper tubing. If I use two 3.6V 880mAh 16340 Lithium Ion I can fit the board and recharge port in the saber, but would that be enough?
