What's the best insolation to wrap with so that it protects enough so no malfunction occurs after being kept outside through freezing winters?
Could I cover with felt pads, and a zip lock bag, in a wooden box? Or would a plastic container be better? I could make both the wood or plastic boxes airtight, I just don't know which is better to go with. Any other advise or different materials to use altogether?
Block styrofoam or felt? Which is better? Or if I use both once one should go first?
