oscilloscope art

[Zo-lee]

Hi guys,

As I started to play with my recently repaired Tek 2215 and turning all the knobs every possible directions I found some interesting form and shape on the screen. IMO there are some quite good one, so I decided to share.

I googled it and turned out "oscilloscope art" is exist so it's not my invention but my babies are dear to me .

I used the 2215 and my MHS-5200A function generator both channel connected. Scope's vertical mode: "both" and "add". And turned all the knobs like a DJ.

3 pictures attached but there are much more.

If you have photos about your art works please share with me.
If you have questions about the details or want to see more pictures of mine please ask.
If you think I am an idiot please keep it to yourself.

Cheers

Can your oscilloscope do this?

Nice, please show more.

NOOOO and me neither

That's just amazing, but I think they use the oscilloscope as a display showing a computer created complex waveform. So this is a little different.
What I was doing is manipulate two waveform with an analogue scope. Pure analogue.

Thanks for the threads recommendation, the Rossler attractor is very interesting definitely worth a try.

I attached 3 more. Playing with them just pure fun.

Great stuff. 
Keep them coming.

Here is an animated example made using a PC soundcard:

This is awesome! Love that they manage to make something that both looks and sounds good at the same time!

'Jerobeam Fenderson' has a bunch of oscilloscope art videos on Youtube.

This one is good: drawing mushrooms on an oscilloscope- same mushroom that had a cameo in one of the videos posted earlier in the thread.

Very nice artwork indeed!

The cool thing about the Jerobeam Fenderson videos is that the audio you hear is what is creating the display.   But you are correct, it is a complex waveform generated on the computer.  The scope is in XY mode and one channel of the stereo audio drives the X axis and the other channel drives the Y axis.  So you can draw pretty much anything that way if you don't care what the waveform sounds like.  But he puts a lot of work into getting the waveforms made in a way that produces the images and still sounds good as well, and that's what makes his work interesting.  You can watch and think about how the audio makes the image.   

Your images are very interesting as well.  Good work.

Just watched all the Jerobeam Fenderson videos and sent a donation while I was at it.

His job is just awesome, perfect balance between visual and audio pleasure. It's got rythm, melody, diversity... You can hear he sometimes plays with repeat frequency to keep the music varying and interesting yet without visibly disturbing the graphic pattern, and holds beautiful visual patterns that sound a bit too awkward just the right amount of time so you can appreciate them with the eyes without them starting to disturb your ears. Real work of art. Interestingly some stuff that looks great is also perfectly good 8-bit music.

That's a very stark contrast with any other scope graphics video I've seen before where the sound (usually provided separately so you can try yourself, the video has 3rd-party music) had no attention whatsoever and is simply unbearable. Here you can connect your sound card output to see the actual result, while at the same time put a headset on to listen to it and enjoy it. He makes 3D animated graphics you can listen to and that's just insane... AND to top it off he can even mix that live.

Yes, exactly. You can plug the audio on those youtube videos into your analogue oscilloscope and see those images. What you see is what you hear!

I've always wanted to actually hook my laptop up to my scope and see it work.   Not that I doubt it works, but I wonder if anyone but Jerobeam Fenderson himself has done it.  But I never got around to it...

Do it! I didn't believe it at first, so I had to try it. Those images are definitely in the audio signal that you hear. I wasn't able to get the same level of black/white separation as he shows in his videos, I found a very noticeable trace between graphics - but that is probably due to the scope that I used.

Not quite. In the comments to one of his videos, he does say that the compression applied by Youtube messes up the visuals. He does make 192 kbps audio available so you can play it yourself. I tried, but my awful sound card made it look pretty bad (it doesn't support 192 kbps). First half of the mushroom one worked though.

You are seeing what you hear in this one too.

[crispy_tofu]

Awesome.

Lissajous patterns created with 4 oscillators (all approximately sine waves) and the Tektronix RM503 scope in x-y mode:

I like how at times the trace looks like a stable 3D object rotating.   Someone who knows more than I do about 3D graphics could possibly explain how a few oscillators could create that effect and even relate them to the equations of 3D to 2D projection.

Damn.  Another rabbit hole to go down for several hours.  I've looked at some of the first link.  Quite impressive.  Haven't got through half of it yet and it's giving me ideas...

I turned an old Tek 213 into a tiny aquarium, complete with a vector fish:

Yes, it's either an aquarium *or* the bumper of every car in the Bible Belt.

(That's actually why I snapped the picture, because I thought it looked like a Jesusfish. Incidentally, when I used to have a real aquarium, I actually tried keeping some Jesusfish... Unfortunately, every time I put them in the tank the water would turn to wine and kill all the other fish! So I decided to keep Darwinfish instead, but they kept evolving legs and climbing out of the tank! I finally gave up. Keeping an aquarium is hard!)
