       | behind that project wants to make integrate all that on a single
       | chip.

       | Non Linear Circuit's Tripple Sloth is probably worth a mention:

       | I built something similar (Chua's circuit) for an electronics
       | course in college[1]. It was a lot of fun. While testing it, we
       | couldn't get it to display the phase portraits on an oscilloscope
       | for a long time, and then we realised we were using a modern
       | "digital" oscilloscope. I think the (high but finite) sampling
       | rate was not enough. The professor found an old analog one from
       | the 80s in his lab and then we got the pretty phase portraits.
       | This site was super helpful at that time (2016)[2]
