For everyone saying "I've seen this before"; yes, yes you have. It was released commercially back when optical disks were... relevant.
Released 23 years ago, discontinued 15 years ago: https://en.wikipedia.org/wiki/DiscT@2
Pretty sure Technology Connections has a video that mentions it.
How famous is Lemmy? The linked hackaday post seems to be from 2022, the github page had last activity 3 years ago.
Perhaps hackernews was a middlestep: https://news.ycombinator.com/item?id=44208283
But otherwise it (activity) may as well originate from my recent Lemmy post: https://old.lemmy.sdf.org/post/36007202 (the old subdomain usually works as well as the API, but the native Lemmy frontend on SDF, 502 or long wait)
I've also seen Lemmy being used as a source for something on Linus Tech Tips.
The author of the article is on the Fediverse, so it's possible.
Btw, the technique is called DVD data art.
Finally, we can write data to a CD ourselves!
Since you’re burning audio data to create the visual image, you can’t also store data, etc.
I mean it looks kind of cool but then other than that what's the point?
Its just neat
I think it could be forked to append images to actual audio tracks, but I am too dumb to do so.
Using old discs for something neat.
How to burn that? It's reported by file as SIMH tape data, Xfburn/Brasero don't recognize it as valid audio track and data burning provides no image. The software-proposed cdrecord command errors out.
What's the error? I've played around with this successfully.
ssu is like sudo on diet.
If this is CD-RW try cdrecord blank=fast first if it isn't blank. Just an idea.
Ah wait, this doesn't work with DVD and DVD burners?
Ah, no. It's for CDs only. Specifically Mode 2 used for audio since that gives more control over what is 1 and 0.
Based on a different similar project: https://www.instructables.com/Burning-visible-images-onto-CD-Rs-with-data-beta/
Welp. Still was an interesting journey.
Someone just needs to make a double sided CD-R so we can have data and artwork on it.
I feel like I remember someone doing this like 10 years ago. Can't find a link.
Now I'm off to find a CD and a computer with a CD rw drive. Wish me luck!
I understand it only works with CDs, but does this work with DVD burners, while burning CDs? Or does it require a CD-only burner?
