Wireless Mini Gaming Wheel

thingiverse

I needed a steering wheel for driving tractors in Farming Simulator. However I didn't have a pile of money and I also didn't need all those fancy bells and whistles normal racing wheels have. I just needed a simple small wheel so I could have fine steering control. This wheel gets somewhere around 900 degrees of rotation. It's geared to a 10k potentiometer of standard size. I use a set of foot pedals from a broken PS2 wheel I got at a thrift store, but there are several designs elsewhere on thingiverse. It also uses some standard hardware: standard 10k potentiometer 2x 608 bearings 2x 605 bearings 2x 8mm or 5/16th bolts, hex head 2x 6mm bolts with wing nuts for mounting 3x 5mm bolts for connecting the frame to the back bracket some 3mm bolts for mounting the potentiometer bracket and other things The electronics uses an arduino pro mini and NRF24L01 wireless board put together dead bug style and powered by an 18650. The NRF is powered through a diode to make sure the voltage doesn't exceed its 3.3v rating. The receiver is an arduino micro with an NRF board as well. The arduino code is here: https://github.com/zimirken/wireless_joystick Some people may wonder about the latency. I tested it and found that there is about 7-8ms of latency, which is better than some of the current gen console wireless controllers. You can find the details of the testing on the github. This means that the NRF modules are extremely fast and are perfect for wireless controllers.
