I have a 1.25 to 28 V variable power supply I'm working on. here's the schematic (from here):
What I'd like to do is put in a fan (12v 0.16A) so it runs when i turn it on, however i don't know where to insert it so that it doesn't blow. I was also thinking of putting in a small bulb as an indicator light - when i turn it up, the light gets brighter. I have quite a few different rated lights, so I'm good for that, but still- don't know how to set it up.
I'll be using a cheap multimeter as a voltmeter - i don't have a standalone voltmeter on it's own and they are quite expensive actually for something so simple.
