Hey guys,
Recently I built the Liquid Sky, based on the idea of rog8811(http://www.rog8811.com/liquidsky.htm) using a pc cooler , glass mirror and 50mW green laser pen running at 3 volts. To adjust the speed of cooler and voltage of laser pen, I built a circuit based on TIP32, powered by 9 volts. I know! I should have used a trimpot! Was not available here at home.
The question is, TIP32 used to adjust the voltage of the laser pen can work dissipating the 6 volts constantly?
Hug,
Andre
