Your task is to build a nearly silent electronic gauge controlled by an Arduino board, a small bipolar stepper motor (Switec x27.168), and a TMC2100 or TMC2130 stepper driver. The TMC2100 series chip should be the best option for silent movement with their silent-chop ability, but we are open for other options. The gauge powered by the stepper will be showing data passed from a usb port and will move in small to large increments. We will provide the computer program to move the gauge. The only power source will be the 5v power from the usb port.
You will need to order and assemble the parts to manufacture a prototype of your design. You will take a video with sound of the product working, and (if successful) will ship that assembled product with assembly instructions to us for further testing. An identical prototype may be assembled to your specifications for side-by-side testing.
The Ideal candidate will have experience with Arduino, stepper motor drivers, microstepping, and electronic prototyping. We would like to hear any directly applicable experience and more about your plan to complete this project. Include an estimate of the number of hours it would take to complete the prototype detailed above.
