My friends and I had the idea to build a climbing wall using climbing holds with embedded LEDs instead of taping holds to indicate routes. In the spirit of "go big or go home", we decided to build a really big wall for Burning Man! We're excited to use the wall for even more cool things there -- like visualizing music and playing climbing games! (The completed wall is the third picture -- it was a pretty sweet experience!)
We've been iterating on design and manufacturing for the holds for the past few months and finally locked down on design, materials, and electronics. This Instructable will teach you how to make one of these holds, how to mount it to a wall you build, and how to control the holds to set a route or have a light show dance party (our system is controllable by anything from an Arduino to a professional lighting system, and a lot of things in between.). I will also explain some design decisions we made along the way. We will not be going over how to build a climbing wall; there are some excellent Instructables already on how to build a climbing wall, and I encourage you to look over those for ideas.
To start, all of our code to control the lights and Eagle files for the boards (both open source!) can be found on our github page
