Previously I just played around with a faulty DVD burner to make some lame stripes: https://lemmy.sdf.org/post/28673131
Used software
https://github.com/arduinocelentano/cdimage
It creates an audio track with carefully placed data to create visible images with pits and lands.
Quite crazy when you realize that this is a 5.38km long spiral
So… yeah… did I say I don’t know to use GIMP? Well, how about some LibreOffice tomfoolery?
The presets needed a bit of fine-tuning since it isn’t exactly the same Verbatim disc, but it was close enough already.
Other attempts
1st attempt with default values
Thankfully it was pretty close, and I only had to change 1st track length. Although it still doesn’t look quite perfect. I am not sure what “Track delta” could be, and honestly not even the 1st track. Maybe the former refers to exact track pitch? Dunno.

A regular photo
Looks good. The photo source is X (formerly known as Twitter), so that sucks source-wise.
But an alternative is here: https://railcolornews.com/2023/11/20/cz-finally-bolt-the-railway-dog-reveals-locomotive-name-after-himself/
As the URL hints, this is a photo from Czech Railways’ introduction of Siemens Vectron locomotive named “Boltík” after Bolt’s fursona.
Unfortunately, it’s missing the name after being repainted, I don’t know what’s up with that, but that’s also off-topic.
Sound sample
So, the images are cool, and they are quite crisp (if I don’t use LibreOffice as image editor xD), but how does it sound?
You see, it’s just an audio track.
Here you go: https://files.catbox.moe/kjhumj.flac
And for Lemmy WebUI users, an embed should work too:
Maybe. It’s FLAC, I’ve used it with MP3 successfully, will depend on browser too.
Most apps try to display this audio as picture, but there is no picture. Well, I mean, technically a few meters of it.
this is the coolest thing i habe ever Seen, probably. i will sooooo try it out later…
Thank you for the FLAC. Combined with my Shure 440a headphones, I was delighted to hear a god awful noise in the highest of qualities.
now THATS optical media
my optics are mediated
This is rad AF.
Keep doing what you’re doing.
lightScribe but different and more volatile.
if you had lightscribes you could do that on top and this on the bottom. tho you may create a black hole.
i dont understand this but im utterly mystified and happy to see the 196 icons i made just being out in so much insanely cool shit i cant fathom
I tried burning a couple using this software when I came across your stripey post, but on the discs I had, none of the presets came close to your first attempt here. It was all just “noise”. Looksgreat! Now I wanna try again.
Has anyone ever seen this tried with photoresist?
I’m assuming “Blu-ray” is likely sales slang for 405nm near UV -ray. 405nm light works well with typical photoresist film. It would be a pain to cut a circuit board to the required dimensions and balance it, but holy crap the resolution is insane beyond anything one can easily achieve with a transparency based exposure.
I have several sheets of ultra thin double sided copper clad and thin FR4 blanks I wanted to use to make 6+ layer boards for kicks and giggles but have never been motivated enough to master through hole platting; holding on to unrealized dreams of strike expanding a thin copper cylinder made of wire, cut to size, and a spot of solder paste on the connected layer, - in other words massively tedious work to unlock unlimited smallness like phone class circuit compactness… until I realized I can’t solo-effort-create what takes hundreds of people IRL and designing tiny is a PITA.
Still, economic access to tiny processes is a tools of the future level hack… I suppose it will be very challenging to access the focal range of the laser in this system. Cool thing to think about though.
This is honestly the most amazing thing I’ve seen all week. I’m trying this out tomorrow. So cool!
woah cool :0
libreoffice is hilarious
The embed is greyed out for some reason.
Expected, might not work everywhere. It’s broken in Chrome, but working in Firefox from my test.
