Adventures in vibrating platform fabrication: so for my cytoplasm sculpture, I started with making a box and immediately completely hated it. It needed to be atleast round, if not more organic shaped. So I drew inspiration from my existing micrograph:
My original design called for three 1.75″ plywood parts stacked together, to be CNC routed. I started (above) but needed a different bit. Unfortunately the motor driver on the CNC burned out after that, so I tried to have it done at milwaukee makerspace- when there computer power supply burned out. So the guy that was helping me suggested to laser cut it- their laser cutter is a few inches bigger (makes a huge difference). Meanwhile I still have this thick plywood that is actually sort of pretty, with a weird ass shape carved in it.
So I made my design a bit less tall and we cut it out of 1/4″ baltic birch plywood, in 12 layers.
^Notch for motor
I really struggled with the design, I did not want to make the membrane outline too thick, it’s a membrane after all. But I needed something to conceal both the arduino and the vibration motor, hence the ginormous membrane. In the final version, the arduino creates a dark corner, but oh well. There was also a lot of guess work in anticipating how much room would be needed for the thing to vibrate, as well.
