Collaborate Disseminate
[Fearless Night]’s optical theremin project takes advantage of the kind of highly-integrated parts that are available to the modern hacker and hobbyist in all the right ways. The result is …read more Continue reading Optical Theremin Makes Eerie Audio with Few Parts
As the pandemic rages on, so does the desire to spend the idle hours tinkering. [knaylor1] spent the second UK lockdown making a sweet Theremin-inspired noise machine with a low parts count that looks like a ton of fun.
It works like this: either shine some light on the photocells, …read more

It wouldn’t be October without Halloween, and it wouldn’t be Halloween without some spooky music. There’s no instrument spookier than a Theremin, which also happens to be one of the world’s first electronic instruments.
You’ve no doubt heard the eerie, otherworldly tones of the Theremin in various 1950s sci-fi films, …read more

Hackaday Editors Mike Szczys and Elliot Williams are back after last week’s holiday break to track down all of the hacks you missed. There are some doozies; a selfie-drone controlled by your body position, a Theremin that sings better than you can, how about a BGA hand-soldering project whose creator …read more
Every once in a while, we come across a project that adds a ridiculously good twist on an existing design. This is exactly what [Xiao Xiao] and the team at LAM research group at the Institut d’Alembert in Paris have done. Their project T-VOKS is a singing and Speaking Theremin …read more
Next year we’re arguably coming up on the centennial of electronic music, depending on whether you count the invention or the patent for the theremin its creation. Either way, this observation is early, so start arguing about it now. If you want to celebrate the century of the theremin, how …read more

If you want to visualize sound waves, you reach for your oscilloscope, right? That wasn’t an option in 1905 so physicist [Heinrich Rubens] came up with another way involving flames. [Luke Guigliano] and [Will Peterson] built one of these tubes — known as a Rubens’ tube — and will show you how you can, too. You can see a video of their results, below. Just in case a flame oscilloscope isn’t enough to attract your interest, they are driving the thing with a theremin for extra nerd points.
The guys show a short flame run and one with tall flames. …read more
We don’t think [bleepbit] will take offense when we say the “poor man’s theremin” looks cheesy — after all, it was built in a cheese container. Actually, it isn’t a bad case for a simple device, as you can see in the picture and the video below. Unlike a traditional theremin, the device uses ultrasonics to detect how far away your hand is and modifies the sound based on that.
There are also two buttons — one to turn the sound off and another to cycle through some effects. We liked how it looked like a retro cassette, though. The …read more

The theremin is, for some reason, what people think of first when they think of electronic musical instruments. Maybe that’s because it was arguably the first purely electronic musical instrument, or because there’s no mechanical analog to something that makes sound simply by waving your hand over it. This project takes that idea and cranks it up to eleven. It’s a portable synthesizer that’s controlled by IR reflectors. Just wave your hand in front of it, and that’s what pitch is going to sound.
The audio hardware for this synth is, like so many winners in the Musical Instrument Challenge …read more
Having never use a 555 before, [lonesoulsurfer] decided that his first foray into the world’s most popular and versatile IC would be to use a 555 to make beautiful chiptunes. For that, we commend him. He found [Dean Segovis]’ Slidersynth light-based Theremin and got to work building his own version it and stuffing it into a (knockoff!) NES controller.
For the uninitiated, a Theremin is a touch-less synthesizer that uses human capacitance and a pair of antennae to control oscillation and amplitude. In a light-based Theremin such as this one, the oscillation is controlled by the intensity of photons from …read more
