 One can build a Chua's Circuit with the analog computer [[https://paperpcb.dernulleffekt.de/doku.php?id=analog_computer:analog_computer_main|Confetti]]. Two modules are needed: the Chua's Diode and a Gyrator. A Gyrator is more handy than an inductor so one can use it instead.\\ One can build a Chua's Circuit with the analog computer [[https://paperpcb.dernulleffekt.de/doku.php?id=analog_computer:analog_computer_main|Confetti]].
