I’m preparing to exhibit at Maker Faire Kansas City 2017, and trying to come up with an interactive and educational project for people to play with.

With what I have on hand, I quickly threw together a couple of breadboards, each with a Teensy, some RGB LEDs, and three potentiometers (using Paul Stoffregen’s excellent Sturdy Potentiometer Adapter for Breadboards).

While this would work, it’s not very durable. I need something that lots of people can tinker and play with all weekend, without worrying about replacing disconnected wires.

So, I set out to design a PCB that I can assemble ahead of time, and will hopefully be durable enough to last all weekend. It will also have the bonus of being a tutorial project I can use in classes, workshops, and share online.
