Affordable Custom Input Devices
summary
Workshops show building low-cost custom input hardware using an Arduino Leonardo to emulate keyboard/mouse/gamepad, 3.5 mm switch sockets for standard assistive buttons, and cheap parts (dealer-priced foam joystick knob listed at ~$50). Demonstrations include a force-tuned “super button” with a load cell and haptic feedback, a tiny open adaptive controller alternative to the $99 Xbox unit, and a full motor controller with CAN bus and solenoid brakes driving chairs at 55–60 A per motor. Designs and code are on GitHub.
