Circuitjs is a really nice tool that has tons of demo circuits and even allows for generating sounds. It's fun to tinker with and can lead to some really interesting DIY modules! Online version:

This is a passive (simple) ring modulator that I built based on this paper. Simply copy the code below and paste it in Circuitjs. File > Import from text

Great find! They even have a Chua Chaos circuit example: tinyurl.com/y2crasmwSo cool! I need to try and build that one for AE Modular at some point. |

I attempted to build the ring modulator that I modeled above in circuitjs, but unfortunately it didn't seem to work as expected.
There was a faint hint of modulation but the two signals simply mixing was much more prominent.
I believe this is due to AEM's audio signal not dropping below zero. When I read the paper it seems that signals must fall below zero in order to get the effect.
Anyway, if anyone more knowledgeable in circuit building wants to give it a go I'm all ears!
