@stan2004 posted:Taking your question at face-value, you can get remarkably inexpensive DC-to-DC step-up "transformers" (oh, all right, converters) with adjustable output:
So these are less than $3 each and include screw-terminals so soldering may not be required. The previously linked example is indeed more compact and potentially puts out more power (I'd have to study the specs more) but at $25 each and apparently requiring soldering...yikes!
Yikes! I didn't realize it was that expensive.
By the way, I have been informed that the PS1 smoke unit draws 0.75-1.0 amps for those of you keeping score at home.
Thanks to everyone that chimed in! Stan2004, that suggestion looks like a winner!
