Search the forum for diodes like the IN4001 and IN4004. They will drop voltage a bit and preserve the amperage, as I uderstand. I have tried 2 IN4001's in series and got a drop just under .75 volts. The Prodigy uses a resistor to reduce output to 5 volts fro 6v. Look through the Puresmoker Prodigy threads, too. Lastly, the LM317 voltage regulator would work well, but is significantly larger than a diode or resistor.

I've seen your fog log before, it's a thing of beauty. I love the way it polishes out.
Would it be too much to ask what size copper pipe you used?

standard 3/4" copper pipe and end caps. It was my favorite mod till I put it in my pants pocket and snapped the connector off!! I'll be rebuilding it soon.
