Fun oscilloscope stuff

[harmo]

Hi everyone,

This is my second post so please bear with my pun-riddled newbie ways. I hope you're all well out there in these crazy times.

I know a lot of you are very serious people with serious scopes. Frankly, I'm at the "kiddy pool" end of the scoping community. I may be decked in ever-so-stylish metaphorical floaties whilst sitting in water too shallow to drown in....possibly a dog bowl...but I'm learning. I don't think I'm alone in finding my initial contact with the scope intimidating (thanks Dave for the "How not to blow up your scope" video)... I'm not there yet, since I only scope "floating" circuits, but it's nice to have goal once I'm more confident... and have a Higher voltage differential probe.

While it is an incredibly useful tool. I feel the humble "scope" has somehow gotten the reputation that's more:

Let's take the fun out of function.

So I thought I'd share a recent discovery for me that was just so unexpectedly interesting (Maybe you know of this already?):



Now, this forum has a thread dedicated to pretty thermal images, and after a grueling and ever-so-comprehensive 1 minute "search and scan of the results" I thought:

Why such little love for the o-scope?

Is there some similar frivolity to be had on the legions of scopes out there? Patterned pulses from well loved CROs, to synthesized samples in newer, more digital devices? I just want to turn people's "scope apprehension" to "scope appreciation".

Please, post some fun stuff, and perhaps comment on how you did it, and what might be generating the signal. Perhaps we can learn something interesting about differing circuits.

Just a humble request, I'd offer more advice, but I don't even have a signal generator yet... and my Arduino got repurposed to a stepper motor controller. My Raspberry Pi was turned into a weather station, and my Ali Express orders are on the slowest boat from China I've ever heard of. (Perhaps they're rowing?).

Anywho, I'll be intrigued to see what fun stuff can be brought to light on a scope.

Kind (sincere, but not serious) Regards,
Harmo.

over 10 years ago someone made this song, Atom Delta, which i still think is the best oscilloscope song out there. Here it is on an analog discovery 2:

I've also been playing with turning drawings into their X and Y components then playing them back with a function generator as waveforms. planning to do a thing with a raspberry pi pico that lets you upload pairs of csv files to its flash memory and use a push button to change which pair is played back, a toy to carry around your oscilloscope drawings

This is a little OT, there are some (frightening) pictures hidden in music and shown on spectrograms.
One can find bunch of similar images and immerse into mixture of popular music and technic. The keywords to search are: spectrogram and skull.

In this github repo there is a program which will plot a gcode file to a scope via a 2-channel function generator -- file xy_gcode_plot.py:

https://github.com/mattwach/fygen/tree/master/examples/gcode

The program is written to interact with a Feeltech function generator (FY-2300, -6600, -6800, -6900, etc.) but the bulk of the program is dedicated to parsing the gcode file and converting it to a list of x,y data points and only after that does it sends the data pairs to the function gen for display so it could be easily adapted for use with other function generators. See the top of the github repo for more details:
