Simulated dashboard for a simulated race

Simulators might have lost their cool for a lot of gamers, but [Fergo] is trying for a comeback. He built an electronic dashboard for a car racing simulator.

[Fergo] spends most of his track time on iRacing, an MMO racing simulator. Possibly due to a little bit of influence from Formula 1 steering wheels, he wanted to add to his dashboard that included Microsoft racing wheel. The dashboard includes RPM lights, a gear indicator, five general buttons, a rotary encoder, and a pit limiter, rev limiter and low fuel indicators.

The build is powered a VB.NET app that connects the iRacing API to an Arduino. To get all those buttons and LEDs talking to the Arduino, [Fergo] used an IO expander that communicates over an I2C bus. It’s a surprisingly simple design that should scale well if [Fergo] ever decides to expand his cockpit. We’re not sure if it could handle controlling a 737, but it would be more than sufficient for a Cessna 172 or Mercury capsule.

Check out [Fergo] tearing around the track with his buttonbox dashboard after the break.
