  • This is extremely cool. I activated the camera and it recognized the position of my hands and I was able to play it as shown in the instructions. It's very fun.
  • Funny I put one of these on my personal site awhile ago. https://www.zchry.org/

    I don't think it works as well as this one.

  • I made one of these recently! Total vibe-code, but exactly the sort of thing that I'd never get around to without.

    Plugged it into Sonic Pi, wired it up to play samples on gestures. Got a nice installation brewing at some point.

  • Really cool. I remember one local musician here in Lithuania used a theremin like 20 years ago and i was amazed at the interactivity and the alien sound of it. Now sitting in front of my computer doing the same that many years later brings memories back!
  • Funny, I guess this idea is in the air (har har).

    I've made a couple things along these lines over the past year. One is a fun, Halloween-themed toy:

    The other is a (slightly) more serious exploration of multivariate time signals as a control signal for an instrument. In the latter case, the instrument is learned/inferred from a segment of input audio:

    This is a really neat idea! Like others here, I'm not a huge fan of the hyper-dense and dripping-with-ai UI, though.

  • Bah, I got part way through making this as an iPhone app and this person beat me to it :P

    Seriously though: nicely done, UX here is better than what I came up with.

  • So many folks in the thread, myself included. Really fun type of project.
  • An iPhone version which used both the front and rear cameras would be far cooler than this, and provide better control too.

    Call it Cameramin and you’ve got a customer. ;)

  • Since a physical theremin is played by non-contact gestures and motions, perhaps your creation might be more aptly termed a "Virtual theremin."
  • I her your point, but this is the theremin version of air guitar, so I think it fits.
  • Although its still kind of working in roughly the same manner as the original theramin - just using a different frequency of electromagnetic radiation.

    Perhaps a "high frequency theramin"?

  • If my Jack Russell is in the right mood, I can make him growl by bringing my hands up as if to stroke him.

    I call this the Therrieremin.

  • Very impressed by the responsiveness of this. But I gotta say, it's much more fun to play a physical theremin, which has slightly different controls (two antennae, one controlling volume and the other pitch).

    https://www.gaudi.ch/OpenTheremin/ will run with an Arduino and it's very satisfying to get better at controlling.

  • I’m going to get pwned one of these days, considering my threshold for giving a random website access to my webcam is apparently mild curiosity and entertainment for 30s.

  • "An overdriven webcam sensor reconfigures its pixels into an AI-steered optical phased array, discharging the laptop's total electrical power as a lethal, coherent laser pulse the instant your hand moves."

    Then it rendered the page load with '<html><h1>"You have been theremin ated".'

  • What would be the attack vector with indirect access to a webcam?
  • I find it a bit suspicious that this exact hand waving data could be used to solve Google's latest reCAPTCHA: https://docs.cloud.google.com/recaptcha/docs/hand-gesture-ve...
