"Programmed" a simple harmonograph on the analog computer. One pendulum (displays red), a 2nd (yellow) and both mixed (green)—sometimes adding, sometimes subtracting. Switch to XY-oscilloscope mode for the Lissajous curve. (Next: double the program to 4 pendulums.) #analog_computer #electronics

I am preparing to put everything out. (I need to make some YouTube videos, document the PCBs and such on GitHub, finish the manual…) I'm hoping it will go out in June.
