Sounds even better tonight with this little PWM controller, running here from ~7 volts but it runs well off of a single 3.7V cell. Need to pick up some Alkaline D Cells but they get like $2 apiece now so ordered a 12 pack on ebay if I don't decide to run it off the 18650's with some little regulator modules on order . . .
