Hey, I know this is probably going to be an extremely simple question, but I'm new to electronics and still learning.
I have this circuit to run a fan off of 2 9v batteries. I want to run two fans off of that one switch, but I don't really know what adjustments to make to the circuit. I know I would need more batteries, and I assume I'd need another voltage regulator, but I don't know how I'd hook it up. Would I just put the other regulator in series with the first and run the new batteries to it? and then that to the new fan? I apologize for the noobish question but as I said, I'm pretty new to electronics.

Make that same circuit again and use a double pole double throw switch. Then you can run them both with one switch and you wont have to mess with the circuit.

IF you're trying to run two fans off the one circuit, just put the fans in parallel with eachother. They'll still need the same voltage , 12 volts each, but will use a little more current, about double if they're the same exact fans.
