The idea is to use a 8-switch relay (or two) to connect to a Raspberry pi and control the switches according to the music. To control the music, hack mpg123 to take a "frames" file which would contain which channel should be switched on or off. For the basic format: [frame #] channel# channel# -channel# e.g. [13] 3 5 9 -4 would imply switch on 3 5 9 and switch off channel 4.
Looking for hackers with the skills:

Build a Single Camera 3D Scanner (Photogrammetry). by lparkin
Description
I want to see how fast I can develop a single-camera (pi camera module v3) rig with a stepper motor controlling a turntable that rotates the model being scanned. The trick here is not to be super fancy with 100's of sensors and data inputs, quite the opposite. I want to see how accurate I can scan objects into 3D-printable models using only a camera and as many fixed and known parameters as possible.
Speed to be augmented with agentic AI coding companion. As it stands, I have a 3D printer, pretty much all the electronics I need.
Goals
- Design and print working/workable camera rig
- Design and print working/workable turntable (considering printing my own cylinder-style bearings as well)
- Assemble rig components into MVP assembly
- Develop application that can hook into existing tools, or leverage a library like openCV, to process 2D images into a 3D model.
- Iterate until models are good enough to 3D print.
