Though it would be nice to share while this is being built and also document myself a bit. Unfortunately the next iteration will happen after Xmas (not going to be at home). It will take weeks of tinkering for sure. The project: Revamp G27 pedals: load cell for brake, following http://www.instructables.com/id/Racing-Sim-brake-pedal-load-cell-interface/step2/Construction/ (75% done) inverted pedals (10% done) pedal vibration for wheel locking (10% done) Dashboard compatible with RF1 engine game (following http://www.racedepartment.com/threads/diy-dash-indicator.89304/) Hardware is pre-made (100%) Tinkering with the sw to mix in the other functionality (0%) Vibration feedback for chair (very much self made, not following anything) Adapt a comfortable chair, integrate with pedal stand (0%) Shaker with telemetry related effects hack subwoofer to build shaker (0%) amplifier for shaker, might scrap some for old hifi. (0%) rpm effects using voltage controlled oscillator and arduino (50%) ...? Supporting infrastructure RF1 plugin that sends telemetry data to network socket (taken from https://github.com/Grumbel/rfactorlcd) Python scripts that chew the data and control arduino (10%) I may offload later all the python to a separate beaglebone/raspberry pi (0%) Some pics of the load cell test setup: I tested already and works fine. I have just to settle on how much amplification and then solder everything to a little board. Probably also beautifying/reinforcing the load cell support.
