Since last week, I’ve finalized the positions of where I want to place the LEDs. I’ve also decided against El Wire for the time being and I’m going to focus on Neopixel strips and rings.

I’ve also gotten more guitar parts than I have LED parts so far. Note the black tuning pegs and bridge.
Tomorrow I’ll be laser cutting the new pickguard out of clear acrylic. I have an outline traced in CAD already, so fitment after the cutting should be the only obstacle. A friend also suggested I can etch/sand a pattern into the acrylic to make an image, which I’ll be testing as well.
As soon as I get the Arduino, I have a lot of setup and programming to experiment with, so hopefully I’ll have a decent rig by next class.
