Audi DTM Steering Wheel for SimRacing

thingiverse

This is remix of [Formula B1 - (Sim racing) steering wheel](https://www.thingiverse.com/thing:4058270) for Thrustmaster T300 RS wheel base. With other wheel mount or quick-release, this wheel could be also used for another wheel base. All buttons are connected to Arduino Nano with common ground. Arduino Nano is connected to wheel base via mini-Din 6 pin connector (SPI serial protocol), so no external power, drivers or USB connection to PC is needed. More info about HW and Arduino code is here https://rr-m.org/blog/thrustmaster-t300rs-steering-wheel-arduino-emulator/ Arduino pins - buttons: D0 - Start (8) D1 - Select (7) D3 - Shift gear up (1) D4 - R2 (9) D6 - Circle (5) D7 - Cross (6) D8 - Shift gear down (2) D9 - Square (4) D11 - triangle (3) A0 - D-Pad up A1 - D-Pad left A2 - D-Pad right A3 - D-Pad down A4 - L2 (10) A5 - PS (13) Other components used in this project: - Big paddle https://www.thingiverse.com/thing:4840117 - 70mm Hub Adaptor https://www.thingiverse.com/thing:2630578 -------- BoM: - 3D printed parts - 3 mm aluminum sheet (minimum 300 mm x 170 mm) - 6D Carbon Black foil (glossy) [Aliexpress](https://www.aliexpress.com/wholesale?SearchText=6D+Carbon+vinyl) - 6x M5 x 70 mm bolts (DIN 7991) - 6x M5 nuts (DIN 934) - 4x M3 x 8 mm for panel (DIN 912) - 4x M3 threaded insert nuts (for panel) [Aliexpress](https://www.aliexpress.com/wholesale?SearchText=M3+threaded+insert+nuts) - 6x M3 x 25 mm for handles (DIN 912) - 4x M3 x 8 mm for paddles (DIN 7991) - 4x M3 x 8 mm for clutch paddles (DIN 912) - 10x M3 nuts for handles and paddles (DIN 934) - 6x M6 x 8 mm for shifter body (ISO 7380-2) - 6x M4 x 8 mm for shifter body (DIN 7991) - 6x M4 nut for shifter body (DIN 934) - 6x M2.5 x 10 for micro-switches in shifter body - 2x 2.9 mm x 6 mm screw (DIN 7981) for Arduino Nano Terminal Adapter - 3x aluminum pipe 8 x 6 x 26 mm inserts for extra strength (8 mm outer diameter, 6mm inner diameter and 26mm length) - 2x A4 Size Suede (Synthetic Leather) for handles [Aliexpress](https://www.aliexpress.com/wholesale?SearchText=A4+Size+Suede) - 6x Neodynium magnet 20 mm x 3mm - 3x micro-switch for paddles - 12x 12mm mini switch [Aliexpress](https://www.aliexpress.com/wholesale?SearchText=Mini+Switch+12mm) - Arduino Nano [Aliexpress](https://www.aliexpress.com/wholesale?SearchText=+Arduino+nano) - Arduino Nano Terminal Adapter [Aliexpress](https://www.aliexpress.com/wholesale?SearchText=+Arduino+nano+terminal+adapter) - Male mini-Din 6 pin connector (for Thrustmaster wheel base) - Wires
