Racing simulator enthusiast Andrew Huxtable has worked on many projects to enhance the experience with his simulators, and one of these is his gear-shift indicator project. Andrew has used a large single digit 7-segment LED module and mounted a Freetronics EtherTen and a darlington-transistor array circuit to drive the LEDs. There's also a shift light at the top of the display to let you know when to change gear. It works very well and adds to the experience, for example:
