/diy/ - Do It Yourself

Repost since last thread ended.

I plan to rig up a solar-powered aircon system using 2ndhand car components in my summer break (I'm a mechanic and can get this shit cheap), my electronics knowledge starts and ends with cars and 12 volt systems.

Presumably I can get an off-the-shelf system to handle charging the car batteries with the solar panels, but I want to be able to have the system turn on when the interior temperature of the shed reaches a set point, and also have a way to prevent draining the batteries too much; Would running it with an arduino or something be worthwhile, or are there simpler options?
