Hi!

I'm new here, so sorry for the noob questions.
I'm thinking of building a PVC saber based off Ahsoka's saber (I'm trying not to copy other's designs), I plan to learn electronics and hand working from it.
As you know, Ahsoka uses a reverse grip, so what I want is two buttons, one near the pommel, and one near the emitter. I want to use a Hasbro economy soundboard, but I've been thinking, that it would be useful to have one button to switch the saber on with sound, and the other one to switch the LED on without sound.

So could anyone please provide a wiring schematic for it?
Also if I want to add a crystal chamber, what do I need to add?

Thanks for the help!
