QRPMe, Rex Harper’s site for QRP (reduced-power) amateur radio kits, has a nifty little prototyping board that fits inside of a mint tin and could be used for other types of mint tin projects. The board (and a mint tin to house it) cost $12 postpaid.

While you’re on his site, check out some of his other offerings, including a mint tin filled with QRP prototyping parts (secomd image above), tuna tin QRP transmitters, and QRP parts vacuum-sealed inside of tuna cans.
