Along with the etched Ouija-style acrylic top, I will be making an LED base to light the plastic. I need the point the beams into the edges, so I designed a frame that I could build with a chop saw and a drill press. When I ran the idea by my teammate, they suggested that a picture frame would work and that the style built for holding vinyl album sleeves would be close to the ideal size.

We went to a craft store and bought a frame. I was worried it would not be a usable thickness because I had to install an LED strip along the inside, so they all pointed toward the center. Coincidentally, the extruded aluminum frame had a groove approximately the same width as the light strips, so installation was easy.

Placing lights in a frame

I had plenty of power adapters for this kind of light strip, so I connected one to a simple controller. For this version, I picked light strips that output a single color instead of light strips with individually addressable LEDs. Since we'll be adding a microcontroller, it would have been easier to use the addressable LEDs that work on five-volts. Still, I have always wanted to try controlling one of these inexpensive strips with a controller and an amplifier board, so this is my chance. I can always pull back and swap out the lights.
