Here's a quick demo (proof of concept) of a project I've started working on. As the title implies I've converted a wired SSD controller to wireless using a few off the shelf parts and a bit of programming. The video shows it in operation and also with the car inverted to display the changing Led for lane change, I hope that part is visible.
Next part is to continue developing the App to allow editing of settings in the controller, i.e throttle curves, max throttle, time out, code upload etc, This will require a Bluetooth module .
Also I'm waiting on some iPhone vibration motors from ebay for haptic feedback.
