Community Rules

You must post before you leave

Be nice. Assume others have good intent (within reason).

Block or ignore posts, comments, and users that irritate you in some way rather than engaging. Report if they are actually breaking community rules.

Use content warnings and/or mark as NSFW when appropriate. Most posts with content warnings likely need to be marked NSFW.

Most 196 posts are memes, shitposts, cute images, or even just recent things that happened, etc. There is no real theme, but try to avoid posts that are very inflammatory, offensive, very low quality, or very "off topic".

Bigotry is not allowed, this includes (but is not limited to): Homophobia, Transphobia, Racism, Sexism, Abelism, Classism, or discrimination based on things like Ethnicity, Nationality, Language, or Religion.

Avoid shilling for corporations, posting advertisements, or promoting exploitation of workers.

Proselytization, support, or defense of authoritarianism is not welcome. This includes but is not limited to: imperialism, nationalism, genocide denial, ethnic or racial supremacy, fascism, Nazism, Marxism-Leninism, Maoism, etc.

Avoid AI generated content.

Avoid misinformation.

Avoid incomprehensible posts.

No threats or personal attacks.

No spam.

Moderator Guidelines

Moderator Guidelines

  • Don’t be mean to users. Be gentle or neutral.
  • Most moderator actions which have a modlog message should include your username.
  • When in doubt about whether or not a user is problematic, send them a DM.
  • Don’t waste time debating/arguing with problematic users.
  • Assume the best, but don’t tolerate sealioning/just asking questions/concern trolling.
  • Ask another mod to take over cases you struggle with, if you get tired, or when things get personal.
  • Ask the other mods for advice when things get complicated.
  • Share everything you do in the mod matrix, both so several mods aren't unknowingly handling the same issues, but also so you can receive feedback on what you intend to do.
  • Don't rush mod actions. If a case doesn't need to be handled right away, consider taking a short break before getting to it. This is to say, cool down and make room for feedback.
  • Don’t perform too much moderation in the comments, except if you want a verdict to be public or to ask people to dial a convo down/stop. Single comment warnings are okay.
  • Send users concise DMs about verdicts about them, such as bans etc, except in cases where it is clear we don’t want them at all, such as obvious transphobes. No need to notify someone they haven’t been banned of course.
  • Explain to a user why their behavior is problematic and how it is distressing others rather than engage with whatever they are saying. Ask them to avoid this in the future and send them packing if they do not comply.
  • First warn users, then temp ban them, then finally perma ban them when they break the rules or act inappropriately. Skip steps if necessary.
  • Use neutral statements like “this statement can be considered transphobic” rather than “you are being transphobic”.
  • No large decisions or actions without community input (polls or meta posts f.ex.).
  • Large internal decisions (such as ousting a mod) might require a vote, needing more than 50% of the votes to pass. Also consider asking the community for feedback.
  • Remember you are a voluntary moderator. You don’t get paid. Take a break when you need one. Perhaps ask another moderator to step in if necessary.

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.

my optics are mediated

[–] DmMacniel@feddit.org 41 points 3 days ago (1 children)

lightScribe but different and more volatile.

[–] proper@lemmy.world 16 points 3 days ago

if you had lightscribes you could do that on top and this on the bottom. tho you may create a black hole.

[–] Norin@lemmy.world 34 points 3 days ago

This is rad AF.

Keep doing what you’re doing.

[–] jawa22@lemmy.blahaj.zone 15 points 3 days ago

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.

[–] webghost0101@sopuli.xyz 25 points 3 days ago* (last edited 3 days ago)

I wonder how long it will take for someone to create a proper music track that is also a picture when burned to a cd.

[–] Unknown_0671@lemmy.blahaj.zone 14 points 3 days ago

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

[–] Tyoda@lemm.ee 9 points 3 days ago

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.

That music track really takes me back. I haven't listened to Aphex Twin in so long!

[–] Staden_@pawb.social 6 points 3 days ago

woah cool :0

[–] i_am_hiding@aussie.zone 3 points 3 days ago

This is honestly the most amazing thing I've seen all week. I'm trying this out tomorrow. So cool!

[–] TriflingToad@sh.itjust.works 3 points 3 days ago

libreoffice is hilarious

[–] irelephant@lemmy.dbzer0.com 0 points 3 days ago (1 children)

The embed is greyed out for some reason.

[–] user224@lemmy.sdf.org 7 points 3 days ago

Expected, might not work everywhere. It's broken in Chrome, but working in Firefox from my test.
