DIY Sim Racing Force Feedback Wheel – Parts & Hardware Explained (Part 1)

📌 In this video, I start building my DIY Force Feedback (FFB) Gaming Steering Wheel with a dual motor system. This is Part 1: Hardware Overview, where I go through all the core hardware and electronics used in this project, including the motors, motor drivers, controller board, bearings, and other mechanical parts. This series will cover the full build step by step — from hardware selection to assembly, cooling, and testing — so if you’re interested in DIY sim racing gear or force feedback systems, this project is for you. 🔧 Parts Covered in This Video STM32F401C Board 775 Two DC motors BTS7960 Motor driver Bearings & shafts Pulleys and belt system Power Supply Encoder Other... ⬛(2:40 – 3:00) Quick correction: I mentioned a 16-tooth motor pulley, but after rechecking, it’s actually a 12-tooth pulley. That changes the gear ratio to 5:1 instead of 3.75:1, so torque at the wheel is multiplied by five. Peak torque per 775 ≈ 0.9 Nm (my motor specs mentioned) Per motor at wheel: 0.9 Nm × 5 = 4.5 Nm With two motors: 4.5 Nm × 2 = 9.0 Nm Typical timing belt efficiency: 90% efficiency (because of belt flex): 7–9 Nm peak torque. 🎮 Upcoming Videos in This Series Part 2: Assembly (motors, pulleys, belt, encoder, bearings) Part 3: Cooling system for motors & driver Testing, tuning & gameplay #DIYSteeringWheel #FFBWheel #SimRacingDIY
