As a part of his ongoing PorscheKart venture, YouTuber Wesley Kagan wished a greater solution to steer his V12 custom-built race automobile, because the earlier wheel was merely a mechanical linkage to the entrance steering. As an alternative, this new version would carefully mimic the structure and performance of an precise System 1 wheel, full with all the buttons, dials, switches, and the central display.

The bottom of the wheel was shaped from a laser-cut sheet of aluminum whereas the encompassing grips have been painstakingly 3D-printed out of TPU filament. For the electronics, Kagan determined to make use of a pair of Arduino Micros, which have been cut up between dealing with button inputs and driving the show, whereas an Arduino Mega 2560 gathers sensor knowledge and sends it as a string to the 2 boards. Due to the restricted variety of pins, he wired every of the three rotary switches’ output pins to a in another way valued resistor, thereby letting the analog enter on the Micro know which place is chosen by the incoming voltage.

The ultimate steps of constructing this upgraded steering included connecting the three.5” LCD display to one of many Arduino Micro boards and wiring every little thing along with the assistance of a pair harnesses to reduce the mess. Nonetheless, creating the graphics program proved to be a problem as a result of restricted house in ROM for storing all the draw operate calls, which is why Kagan plans on finally swapping it out for a static picture that has the values filled-in.
