Those touch sensors from the first DIY $100 controller didn’t work out so well- so the design has been updated with some good old knobs borrowed from a spare vci-100. I have filmed the DIY tutorial but editing is taking much longer than anticipated so the final step by step guide will be up on Monday. In the mean time that gives you a chance to go buy all the parts you want and plan your $100 controller over the weekend. Sliders, more buttons- its all game but try and keep it simple.
Those LEDS wont work with the HID interface device I eventually used for the project but I still found a cool way to wire them directly to the knobs so as the knob gets turned up-they get brighter. Its simple stuff but useful and fun to do, so you might want to pick up a few LEDS at the same time.
