I'm thinking of designing a heat controlling system attached to the cars power. But I'm not exactly 100% sure and this is where I need everyones collaborative efforts (we're all brilliant) and togeather we can solve these problems.
I'm thinking of attaching a Basic Stamp2 Processor Basic Stamp2 to the vehicle's power supply (almost directly with no switch, so that it will always be on) This probably won't drain the battery because it needs almost nothing to run, I think it draws less power than one of those alarm lights (used to visibally show someone that your car has a car alarm active). This Basic Stamp2, will constantly monitor the temprature if the temp inside my pc gets below certian degrees then turn on some type of heating device).
Here's where I need your help ! What the hell kind of heating device that needs low power to operate and can keep (say my harddrive) above freezing over the course of a new england winter night, WITHOUT draining my trucks battery.
Let's think Liquids, or GELS (if possible) but I'm open to ANY IDEAS here.. don't hold back.
