Behold the most amazing arcade hack in existence: Matt Brailsford, AKA Circuitbeard, crammed Sega's OutRun into a Tomy Turnin' Turbo dashboard. [via]
Some key features are an integrated 3.5" TFT screen, fully usable steering wheel and gear shifter (dashboard turbo light comes on when in high gear), working ignition key for power, true MPH speed and rev counter displays, and a fuel gauge to represent the stage time remaining.
The project itself was quite a big one for me, filled with several moments of frustration, from burnt out potentiometers, to soldering LEDs backwards, multiple TFT screen purchases and more than one change in direction as approaches to problems were found to be inadequate.
All the toy's hardware is hooked up to the game, running on a Raspberry Pi with a PiCade board and Kookye 3.5" display. He worked around the lack of pedals by using the gearshift to accelerate and brake. How he made a physical LED dashboard to show the in-game speed completely escapes me. Genius!
Here's the original mechanical toy, for reference:
