Reply to "Recommendation Wanted for DC step-up transformer"

What he said.

And with similar pricing (less than $5), you can get a DC-to-DC step-down converter module. To keep things simple, no soldering, etc., you could use 2 step-down converter modules both powered by your 12V DC supply. One would be set to 7-9 VDC as GRJ suggests to power the heater resistors. The other would be set to 3-5V DC to power the fan motors.

One DC-to-DC step-down module could certainly power all 4 fan motors. From power limitations driving 4 heaters with 1 DC-to-DC step-down module may be pushing it (depending on which converter you have) so maybe you use 2 converters and each powers 2 heaters.

Plus, I'd think the PS2 smoke units would be more readily available (and less expensive) than PS1 smoke units?

Addendum:

For about $3, you can get a DC-to-DC step-down converter with a built-in digital voltmeter!
