In the video:
Hall sensor + Magnet (tachometer)
Drum Brake for adding load
Strain Gauge in the back to monitor torque
Rest of the electrical wiring is for measuring input power and output power (electrical)
I created this gaming rig for a client, designed to be lightweight and cheap, it was made out 1" round tubing and some laser cut metal sheets.
Features:
Adjustable pedal rest angle
Variable Mounting Holes for different Steering types
LCD Vesa Mount Slots for height adjustability
I had to diagnose and troubleshoot the faults with all the electronics and eventually ended up switching out the old board and installed new firmware and a bed leveling sensor!
