Hi Guys I am pretty new to electronics, I have a basic knowledge and for the rest I am learning as well as I can
I have a project that needs cooling, a ccd camera. This I did with a 5v peltier element on the ccd itself, with a chunky heatsink, and the biggest fan I could find, a 12v computer fan. Is there any way to power them both off a 12v power supply without too much trouble? A peltier control board is off the cards (too expensive) I doubt I can make one. I tried to drop the voltage with just a resistor but the peltier resistance varies wildly with temperature.
Help a noobie out
