If you do not know much about electronics, you should not attempt such a thing. Do research on electronics first, learn what you need, and then start small. If you just jump right in there is real danger of damaging the saber and/or yourself.
I know it's risky, an I have a friend who's good at this stuff who said he would help. Basically, I was just asking for the Dummys version for myself, and also for advice on what board to use, etc.
