![]() The circuit can be tweaked by varying R6 from 0 to 2k. I chose the LT1351 op amp, since it should be quite near the common TL071 series op amps, and the model comes ready with the LTSpice installation. Would be nice to see a single-supply version by the way! There are two outputs, nodes V1 and V2. The circuit is powered by two 9V sources, one positive and one negative. If you want to try simulating the circuit yourself, click here to download the. I built a circuit with LTSpice based those two pages. Another page I found had a quite similar circuit but with a little bit different component values. The first result was this great page giving me a nice schematic and details on the circuit. I haven't built the circuit yet, but I did some simulations with LTSpice IV and here's what I found out.įirst, I googled for schematics. Still, Chua's circuit is very interesting to fiddle with. It has so many stages that can saturate to give different waveforms. Also there should be much less variety than in the waveforms of the Elektor circuit. The downside with this simple circuit is that you need an inductor which you might have to wind up yourself. You can read all about it in the PDF they published.Įlektor's Chaos Generator won't fit in your pocket.Ī much simpler chaos generator that can be built with a lot less components is called Chua's circuit. ![]() Their design is somewhat complicated, with a total of 13 stages of 7 different circuit blocks. I had been reading on chaos generators in the past, and this e-mail got me interested again. The event is due 15th of December at 6:00 PM EET, so if you have nothing better to do, that's one good way to waste your time. From time to time I get spam from Farnell (a component distributor), and on their newsletter they're promoting a free webinar by Elektor magazine, titled "Let's Build a Chaos Generator!". ![]()
