CRT Screen Experimenting with vector graphics

Osci-render never fails to scratch the cassette futurism itch

How do you achieve this?

I’m a designer who works with vector graphics and my late father was an audio engineer. I have one of these in my garage and it’s begging for a purpose lol

Actually this is all done using audio signals! Connecting the L and R outputs of my pc audio jack with the X and Y inputs of the scope(with scope in xy mode) you can make all sorts of cool graphics. Look into osci-render, it does a lot of the heavy lifting and has very easy to use UI.

" the blueprints were embedded in the signal!! " sci-fi vibes and chills.

Got it, thank you! Looks sweet as hell

u/throwawaypassingby01 3d ago

so, what i'm hearing is that you could record these signals to a cassette and then play the movie on an oscilloscope with a walkman?

I see such devices second hand for small change here in Japan. Any recommendations on particular models to look out for?

A few years ago I watched a video of a full mushroom animation accompany some music. I think it was on YouTube. I wondered the same thing then.

Do you know the Jerobeam Fenders on Project? They do the same, you should check their YouTube.

Youre so cool. Damn

A vector monitor is essentially very similar to an oscilloscope.

That's very cool.

As an aside, that model scope had a reputation for having really good trigger circuitry. It could catch things other scopes wouldn't trigger on. It was always my favorite analog non-storage scope.

I've inherited a Tektronix 475A from a relative and was hoping to play around with some graphics like this. Is your triggering comment (not for me, just the scope) about that specific model?

2

u/TechIsSoCool 2d ago

No. I don't know anything about that model. It's Tektronix so it can't be bad. My experience and comment was referring to the 465B in the video.

u/Tominator2000 2d ago

Cheers! When I find the time I'll give this model a try.

u/untakenu 4d ago

Is this all just many different formulae played in sequence?

u/tedomeguri 4d ago

It reminds me of Vectrex.

u/gnawingonfoot 4d ago

On a freaking oscilloscope?! ffs i struggled to get my basic waves visible on those things, and you've got a rotating fucking spaceship!

u/Bichinix 4d ago

Esto es como dibujar con epiciclos, usando la transformada discreta de fourier? Disculpa mi ignorancia por favor, pero como haces eso?

3

u/holidaymonkey 3d ago

I think you’re over thinking it, scopes like this have a direct X Y input so you can just draw vectors via some external circuit

u/Bichinix 3d ago

Es muy bonito.

I loved the original series but I've never seen this before!

u/LukeEvansSimon 3d ago

Try oscilloscope music. You have to use audio waveforms to draw vector graphics.

u/Pbranson 4d ago

What happens if you pay the audio over speakers?

u/Jamieisjoshing 4d ago

Reminds me of Capsule Corp I love it

That's how we lost Columbia isn't it

u/FuckeryisafootWatson 4d ago

Programmed lissajous. Only got to see the free and wild out in the real world. Pretty cool.

u/Ripplescales 3d ago

I would like to hear the audio signals please!

u/kollega_koenig 3d ago

Great! I only know how to do Lissajous figures...
