While working at Stoko, I was asked to build a cyclic tester capable of running more than a million cycles, without failing, in order to test lifetime estimates of the company's product (an athletic tight that doubles as a knee brace). The machine was designed to be as robust and modular as possible to adapt to an everchanging use-case, such as fabric pilling tests, stretch and recovery of fabric, and hardware ware and tear. It features a powerline band pass filter to prevent motor noise from disrupting the microcontroller, a motor assembly that can be moved anywhere on a peg board, cycle counts, and a timer.
