#1937 Chua's Circuit (part 1 of 2)

Episode 1937

It's so serendipitous that the most fundamental unit of circuit exhibiting chaos behaviour is named like half of a chihuahua 💁🏻😉

I've been fascinated with Chua's circuit for decades. Thank you for covering it!

[MIKE_FROM_DETROIT]

I love it. One of the first circuits I ever made for one I got an old oscilloscope. I went with an 18mH inductor like the original. My second circuit was a Scanning tunneling electron microscope utilizing the Z axis on analog CRT scope. Thanks for creating this channel! There is a whole "zoo" of different, beautiful chaotic attractors this circuit can output.

Please put the Chua's diode to the curve tracer!

That curve with the three slopes reminds me of the tanh(x) characteristic of an overdriven OTA. I wonder how a single LM13700 would work as a Chua (if it's a Chinese name, it's pronounced 'chwa') diode. Cool idea!

[gretalaube]

The output square waves shown in the paper look like the output of one of my SRD multiplier attempts. ...now it makes sense why that thing never would work right. 73 de W3IHM

It's 2024 and still analog multipliers are an expensive component!

[misterhat]

How does this vary from a tunnel diode?

[staryduren]

Would be interesting to build an array of such circuits loosely coupled ( effect hard to 100% eliminate anyway ) and check what kind of patterns will emerge in array ( each circuit acting as a pixel, for visualization one can assign rectified of x, y, z to R, G, B intensity)

Why not just run the simulator and see the result?
