Hello, I'm using my arduino in a sealed environment to monitor heat and humidity. Currently it's powered by a 12v 500mA wall-wart and the little guy gets a bit warm, not hot, but warm enough to skew the conditions within the environment. Would using a lower voltage power supply, say 7v if I can fi…

Duemilanove, power supplies, and lowering heat.

Awesome, thanks Paul. I'll look for a 7v 600mA unit.
