Hey, I have an idea for a device that I'm trying to fabricate, and I could use some help with the design. Hopefully you can tell me if what I want to do is possible, and what components I'd need. Thanks. My idea is for a device, maybe 6 inches long by four wide that would contain a damp object. When the damp object is inserted, either a pressure switch or some moisture sensors would activate the device and it would begin heating the object either for a specified period of time, or until the object was dry. It would be powered by rechargeable batteries that you could charge via a wall socket, but possibly also powered or partially powered via solar cells. The temperature produced by the device would need to be low enough to be safe to the human touch---maybe 120 degrees fahrenheit. Is this feasable via battery power, and how complicated would the electronics be? Thanks.
