Hi all.
My driver will work with the Hasbro sound modules just fine. I've got 10 of them currently that I'm going to start selling with my drivers soon. The thing is, not all Hasbro modules are created equal. Some are pretty bad, others are fair, and some have good sound, power up, clash, movement and power down. Those are the ones you want (and the ones I have).
My driver will work with the FX sound module too, it just requires an additional component to interface the module to my driver, which I'm currently trying to stock up on. Either sound module will come on and go off in sync with the blade with a single switch.
The Buck Puck and a few other Luxeon drivers work well. They don't have the bells and whistles that my driver does, but not everyone needs extension/retraction, clash, lockup or shimmer. For a simple on/off, a standard current regulator might be the way for you to go. It all depends on what you want.
