This amateur radio club provides kits uniquely packaged in tuna tins. When you build the kit, the tuna tin also serves as a chassis for your new project, complete with a nice label for the tin. Although most of the kits are geared towards QRP (low power ham radio) operators, Make readers might enjoy the “AXEme Picaxe Construction Kit”. This is a Picaxe development board built into one of the famous tuna tins. It’s a very unique and eye-catching way to work with microcontrollers.
