Re: 20'' sinewave display?
Ah ha! This is the one I built - from a 1978 article.
https://www.youtube.com/watch?v=mig4oDcu2qQ I used it as a visual 'attraction' for new electronics students at a college. It worked! Quite a few signed up after talking about the 'science' behind its operation. Check out 'oscilloscope music' on Youtube too! |

There was also a series that ran from Aug to Nov 1968 in Practical Electronics, Experiments with Sound, light and Colour.
