An open source, educational, low-cost modern analog computer

A very popular analog computer patchable with 4mm banana jacks was the Comdyna GP-6. I went down a rabbit hole of reverse engineering it from photos and schematics years ago in order to build a version that would fit in a 3U panel for Eurorack modular synth interfacing. Never finished it, but the total BOM was... well, not much. The panel was going to cost more than the board+opamps+passives. I wanted to buy a real Comdyna but I remember the…

This is amazing. I use the MakeNoise Maths module on my synth to experiment with similar ideas, as I think the next leaps in scaling quantum computing are going to come from a generation of kids who developed a musical level intuition for wave dynamics playing with their parents' analog synths. Digital has been cool and interesting, but when young hackers have the tools and incentives to become de-facto physicists, they're going to tear holes in the fabric of reality…

In my upper-division analog electronics class (the hard one), our lab project throughout the quarter was to build an analog computer that simulated the physics of a bouncing ball. Physical variables of the system were adjustable (gravity constant, coefficient of restitution, etc), and the ball was "released" by pressing a button. The output was viewed on an oscilloscope. One of the hardest 10 weeks of my life, but also one of the most rewarding. Our team was one of the…
