Gamer Builds One-Handed Controller After Losing Their Right Arm

After losing his right arm in a motorcycle accident, Joe built a one-handed PC controller to get back into gaming.

He first modified a Razer Tartarus keypad, then redesigned the idea into ERCHAM with built-in mouse sensing, dual analog sticks, and scroll wheels.

Joe plans to launch a Kickstarter to manufacture the controller for other gamers with disabilities or limited mobility.

The project highlights how player-led hardware innovation can make gaming more accessible.
