i am working on my first LED saber and i have built a cluster of LEDs. i have my LEDs wired up to a hasbro sound board from a new "spring action" saber. the package on the LEDs said that the max power you can put through them is 3.5v. i'm wondering is if anybody knows if the hasbro sound board has some sort of voltage regulator in it. i'd like to be able to use more than 2 AAA batteries in my saber....otherwise i'm just going to end up having to change out batteries every time i duel...
