    I have an idea for a peltier device hand cooling mechanism. I know what parts I need, but I don't have a solid design or know exactly what parts. What I mean by that is, for example, I know I need a battery, but I don't know what size. This device will be single hand held, like a joy stick. It will have a peltier plate, heat sink, fan, and be rechargeable. It will also need a tempature sensor. I will need a design that can be provided to manufacturing for a prototype. Not just a 3D rendering.
