I like 3D printing, 3D modelling (in Autodesk Fusion 360), laser cutting, electronics, Arduino programming, plus some Verilog FPGA programming. My thingiverse page: https://www.thingiverse.com/dAcid/designs
I got interested in 3D printing while trying to replicate a digital pneumatic logic circuit
(like this binary counter https://www.youtube.com/watch?v=IKfNbzCGHf0 or this oscillator inside this robothttps://www.youtube.com/watch?v=1vkQ3SBwuU4)
Here's my feeble attempt at making such a circuit: https://www.instructables.com/member/dAcid/
My ultimate goal would be to make a pneumatic shift register, which would allow lots of pneumatic actuators to be controllable from just one or two solenoid valves.
