I just picked up one of these boards and tried to wire it to a single Cree using a pnp tip42c transistor in the same way as described in the " 2010 Electronic Lightsaber w/ DVD Tutorial" thread. It seemed to be working until I smelt burning. I quickly powered down and discovered the small transistor on the original board was red hot. Any ideas what I did wrong? image.jpgimage.jpg
