Oscilloscope Output - JavaScript

The program for outputting vector images to an oscilloscope via a stereo audio output has long surprised no one. But only in January 2018, they began to write this in JavaScript.

One of the scripts displays an oscilloscope image of the clock face displaying the system time of your device. Another - animates, forcing to rotate and pulsate, the picture you draw. It is incompatible with devices with touch screens: even if you connect the mouse via a USB host, instead of drawing you will scroll the page.

And this video, filmed by Neil Fraser, the author of both scripts, is for those who do not have an oscilloscope, or have one, but no X input.


PS Sorry, we could not get both scripts to display a picture on this oscilloscope emulator running in the next tab. He does not perceive audio from the adjacent tab. And in general, nothing but his own set of audio files, does not perceive.
