I stumbled on this oscilloscope demo that is actually done on a Rigol DS2072 digital oscilloscope. Normally you see these types of demos on oldschool analog scopes. The demo is played via a sound card hooked up to 2 channels of an oscope in XY mode. In XY mode, one channel moves the X axis, one moves the Y axis. There is actually a flac (lossless compressed) audio track downloadable here if you wanted to try it for yourself.
If you’re into this kind of thing you’ve probably seen the Youscope demo, it’s a classic!
If you haven’t check it out below. The audio track for this one is located here.
Pretty awesome demo. So I was actually quite interested in learning more about how these are constructed and I found the video below.
Alan does a pretty good job of explaining the basics of how this works. Alan has a buncha other informative videos on his youtube channel if you are wanting more. Thanks Alan.
