Freeplay3
A MAKE reader writes in with a homemade Freeplay style radio – “Pinouts are described for the Motorola Freecharge, a battery pack with a hand crank for charging, and the hit clips radio cartridge. Solder power terminals from the freecharge to power in on the radio receiver, then solder the speaker terminals to speaker out on the radio receiver, glue it together, and voila – cheap, easy n’ cool hand crank powered radio.”Link.
