Squares, Triangles, Sines...Oh, my. Another Forrest Mims circuit -- approaching the practical limit of the canvas size in EC.

"Shake" the canvas to inject some noise and get it started!

Adjust 100k resistor and/or 10nF cap on bottom op-amp to change oscillation frequency from 1000Hz.

Bottom op amp should oscillate at 1000Hz with DC power, but I can't figure out how to get it going -- there's no way to apply DC voltage like a real op amp. So, I had to use an external AC input. Is there no way to apply DC power to the circuit?

Remove to AC source and just shake to start

Dobry

OK, I put in a simple 1V source with a switch so you can "jolt" it into action.

OMG, I just tried literally "shaking" it and it worked. Hurz, you are a genius!
