Despite what you may have heard from the kids hanging out in the parking lot of Taco Bell, there’s a lot to be said about driving conservatively. Not peeling out after ever red light and stop sign does wonders for the life of your engine, and not slamming on the brakes 50 feet away from an intersection will keep your brake pads going a long time. [aromaoftacoma] wanted a dashboard gauge telling him how good of a driver he is, so when he got a bullduino he knew what he had to do.
[aromaoftacoma]’s project for the Redbull creation contest uses the very cool Arduino shield/Redbull logo known as a bullduino with an accelerometer to track how conservatively he’s driving. Quick stops and starts are murder on an automobile – it’s the same reason your grandmother has had the same car for 20 years – so [aromaoftacoma] made a wonderful display using red and blue LEDs behind each charging bull.
Because simply blinking a LED in response to data pulled from an accelerometer is a little boring, [aromaoftacoma] added a servo to change the orientation of the charging bulls. When he’s driving well, the blue bull is tilted up, and when he stops short the red bull becomes the focus of attention. Not a bad build at all.
