    I used this schematic on my last build. I used a Blade Builder sound board and it came out pretty nice.

    I would check to make sure you've got the correct type of PNP transistor, and recheck your wiring to make sure everything is routed correctly. I know that I had to recheck the diagram several times because it is a bit of an unusual set up.

    I have not built mine yet, but if you are using a string of leds instead of a luxeon or cree, that could be your problem. if the string is from another toy saber, it should mostly work, but if you strung together your own (parallel or series) or bought one of those pre-strung sets, you probably need more voltage. most pre-strung sets require 12v.

    Question: What are the dimensions of this board? Has there finally been a consensus on how many ohms the speaker is, on another thread I saw a guy say it was 8 and no resistor was needed.

    I want to fit it in a 7/8" ID chamber is this even possible?

    Dang, so close. Not worth messing with the hilt just to fit a hasbro cheap-o board.
