CAN Bus hacking is all the rage right now. This particular project uses an early development version of an Arduino compatible CAN bus tool to integrate radar detector control into a Mazda dashboard. This image shows the output as the Whistler Pro-3600 radar detector boots up. The self test demonstrates what you would see on the dashboard display if your speed is checked using any of a handful of technologies. But it’s not just the dash display that’s working. The steering wheel controls are also capable of affecting the radar detector so that it can always be hidden from sight.
With auto manufacturers adding more numerous and larger displays to our vehicles it’s refreshing to see someone come up with a hack that makes pushing our own info to those screens possible. The CANBus Triple is an Arduino compatible board which patches into the data bus found in all modern vehicles. To integrate the Whistler for this hack [TheDukeZip] prototyped the interface on a regular Arduino board, then moved it over to the CANBus Triple once he had it working. Check out the video after the break to see the setup in action.
