This repository is the mechanical and electronics design for a DIY sim racing force feedback pedal. It contains CAD models (Fusion 360, STEP, STL) for 3D-printed and machined parts, detailed soldering guides for several PCB revisions, wiring diagrams, bill of materials, and investigations into key components (ADC, loadcell, brake resistor). The repo does NOT contain any application software, firmware, or data pipelines; it is purely a hardware design and assembly guide. The project is well-documented with multiple design iterations and clear instructions for building a custom FFB pedal using a servo motor, linear rail, loadcell, and ESP32-based control electronics.
