Open source, sonar-controlled vibrator you play like a theremin, with your whole body

Scanlime's Beth modded a remote control vibrator, replacing the interface with an Arduino-based sonar controller that she can activate with any part of her body, playing it like a theremin. The result is pretty cool -- it "closes the feedback loop" between the vibrator's intensity and the user's physical response. The post includes a detailed technical breakdown of the reverse-engineering steps that she used to work out how to hijack the control mechanism, and the steps that went into building the remote, including a 3D printed chassis. The plans are open source hardware (CC-BY-SA), and posted to Github.

This toy serves as a kind of analog bridge between two remote spaces: the column of ultrasonically-oscillating air in front of the remote, and whatever body part happens to be in contact with the vibrator. Touch that invisible space above the remote, and the vibrator touches you.

In fact, it does start to feel like there’s a palpable object in space above the remote’s sensors. Move your body close to it, and it reacts. Press into it lightly, or tease the edges. Flick your hand through it, or make graceful waves back and forth. You can use your whole body to touch it, almost like a big fuzzy vibrating cone floating in air.

If the sensor can see your body’s rhythms, it responds in kind, effortlessly synchronizing to its frequency. This is exactly the sort of closed-loop control I was after.

      1. I was thinking more “A Token Of My Extreme” which is about sex with machines, “But if you want a really good one you have to learn a foreign language,” which used to be German, but now it’s C++ I guess. 

  1. Ya know, I was just thinking it’s been far too long since teledildonics has appeared in the news.

    Wait. No. The other thing. Short. Far too short.

    1. Attempting to compete on specs with the sex toy industry is about as foolish as a mathematician attempting to compete on floating-point operations with the computing industry…

      (speaking of iconic tales of doomed competition, has anybody ever taken the American folklore of John Henry vs. the steam drill and re-shot it as an over-the-top musclebound homoerotic machine sexfest?)

    1. At the state level? Negative quite a few years. Federally? Not much activity that has risen to the level of even preliminary media attention.

  2. Best use of electronic hacking skills I’ve seen all week!

    You really should read the whole article, although it won’t make much sense unless you do electronics.

    1. The article refers to it as being similar to programming your VCR. I personally find that to be an excellent tactile experience, but I’m weird.

  4. The hackaday thread is… tragicomedic. It’s bitterly divided between the ‘eww, why are you getting your gross feminine sex toys in my hacks!’ contingent and the contingent that recognizes it as an atypically well done and written up example of the ‘hacks’ genre.

  5. This does hit me as perhaps the most pretentious sex toy ever invented, but at the same time it is fascinating.
