[Andrea] was helping out a local rally racing team with their car and was asked to create a device that would display the current gear on a big, bright display. Of course, a device like this already exists, but the team didn’t want to invest the significant resources into a ready-made product. Instead, [Andrea] was tasked with creating one.
The device is basically a pot attached to the gear shifter, but in testing, [Andrea] ran into a problem; between reverse and 5th gear, the shifter would turn 360 degrees, meaning these gears were indistinguishable.
The solution to this problem was a calibration procedure for when the driver starts the car. By setting a jumper, the driver puts the car into all gears, sorting out the reading and storing the analog values in the microcontroller’s EEPROM.
Head to head video game action can’t even compare to this use of a coin-op Sega Rally game to race actual RC vehicles. Take a close look at those screens and you’ll see there are no computer graphics, just a feed for a camera on each of the toy cars.
The project was conceived for the Sapo Codebits VI conference in Portugal. The arcade cabinets had their controls connected to an Arduino, but getting video up and running wasn’t nearly as easy. After fruitless attempts to get the original CRTs to work the team ended up replacing them with functioning CRT units of the same size. The cars themselves have two camera, one on top of the vehicle’s cab and one mounted on a boom for a perspective that was above and behind the vehicle. The drivers can switch between either view. The cars were set loose in the room serving as the event’s retro gaming area and players were free to race each other wherever they pleased. Don’t miss the video clip after the break which shows off all of the fun. Continue reading “Coin-op Sega Rally used to race RC cars”
HacDC, Washington DC’s own hackerspace has been kind enough to open their doors (and floors) to fellow hackers planning on visiting DC this weekend for the upcoming Rally to Restore Sanity. They are taking registrations now, and space is limited, so act fast. They have a suggested donation of $20 a night, which will get you floor space and breakfast each morning, as well as the warm feeling of supporting a community based Hackerspace. Details can be found on their registration page, and please make sure you read the rules before registering. Thanks again to HacDC for supporting the Hacker community!
In other news, Hack a Day will be at the Rally, so keep an eye out for the writers wearing the Hack a Day shirts, as well as the HackaDay Twitter. If you get seen with one of us, you might just make it to the fan gallery. We will also be handing out some HackaDay Swag if you catch us soon enough on Saturday.
