Doom Runs on $30 Clamp Meter

Hacker Artur Bieniek ports the classic shooter Doom to the FNIRSI DMC-100 clamp meter, a device costing about $30. The project runs on an Artery AT32F415 chip with 150 MHz speed and 32 KB RAM, loading Freedoom Episode 1 Phase 1 with four save slots and sound effects via a drone controller.
