  • This cat is thoroughly out of the bag. People have been building computer vision powered automatic sentry guns that shoot paint balls or nerf darts or spray water for a while now.

    See, for example, this video from 2012, which was probably about one of the first ones.

    In comparison, here’s a new video from a few weeks ago as part of “YouTube Maker Secret Santa” where the guy built a very good working Nerf replica of a TF2 level 2 sentry gun. He didn’t even bother talking much about the motion tracking part because it was already a solved problem (see timestamp 17:50), so instead he spent the video talking about the ammo chain design and the aesthetics (and playing with the Secret Santa gift he had received from another maker).

    That’s the state of automatic AI turrets in 2025: trivial enough to omit discussion of the tracking tech and cheap enough to build to fit in a Secret Santa gift budget.






  • 1st thing i would do would be call the radio station–they might have a digital copy already

    It hasn’t existed since 2003 (there’s still a station on that frequency, but it’s changed ownership and programming a couple of times). Maybe they still have the old master copies anyway? Or I suppose I could try to track down the DJs who produced it…

    The library and state archives ideas are good suggestions; I’ll look into them.

    last resort would be a recording studio, which might cost lots of money per hour, and it’ll have to be converted in real time–play the tape from start to finish, while the computer ‘records’ it. if the studio don’t have a top of the line gourmet tape deck, then they can take just take the output of your own player and plug it into protools

    I mean, if using my own player might be considered “good enough,” couldn’t I just hook my Walkman’s headphone output to the line in or mic input on my computer and do it myself? In addition to the audio built into the motherboard, I also have a relatively-cheap USB audio interface, which I guess isn’t as good as it could be (it’s 48KHz, not 192KHz) but would still be better than nothing.

    The main thing is I’m not sure how I need to set the volume on the Walkman (it also apparently has a feature called “AVLS” that might or might not be relevant) or if I need an amplifier or something. I also don’t know if I need to do anything special with ALSA/JACK/PulseAudio and know basically nothing about how to use Ardour or XMMS (I’m aware they exist and are the right type of software, but that’s about it).


  • i was a recording engineer during the time analog recording was just starting to get surpassed by digital

    I’ve got a cassette of some parody songs made by a local radio station that’s basically going to become lost media if I don’t digitize it myself. The only cassette players I currently own are a Walkman and one of those retro-style-but-not-old CD/cassette/record combo players. Do you have any advice on what I should do to get the best quality transfer that I can?


  • That’s not how copyright works. Copyright is a legal concept, not a technological or physical one. If the intent was to be inspired by a 3DBenchy and it’s not “transformative” (as in, into a different medium from a 3D model entirely), it’s infringing. It doesn’t matter how many vertices in the mesh are different if the person making it started with a 3DBenchy in mind.

    At best, if your intent is to mock the original, you try to argue that it’s parody and thus fair use, but it would still very definitely be a derivative work regardless. Any further downstream modifications would thus also be assumed to be infringing the copyright of the original unless they were (successfully) claimed to be parody too.






  • Shutting Off X’s Algorithm

    Hey EU, that’s not how any of this works. First of all, you do not have any control over that – even if you demand it be done, there’s no way to verify compliance. Second, there’s always an “algorithm.” There can’t not be an “algorithm;” that would mean it would display nothing at all. Even the choice to just display tweets chronologically is still a choice, and implemented in the form of an “algorithm.”

    What you do have the power to do – and what you should do – is simply just straight-up block X entirely.
