This instrument was built in June 2011.

The clicking heard while attacking the notes is the sound of the touch switch, which is a microswitch whose clicks are heard only by the performer. They are not electrical clicks that might otherwise be passed through to the amplifier.

This instrument has a range of about 4 1/2 octaves with flat frequency response. The camera’s microphone has limited bass response, causing the audio in this clip to roll off toward the bottom end. In reality the bass is just as loud as the rest of the pitches.

man he actually plays it like intended and makes it sound good instead of only spooky music

Kind of makes sense now, how a critic described the sound of a theremin as a cello lost in a dense fog, crying because it doesn’t know how to get home.

Theremins are a bit of an odd instrument to begin with, but [AphexHenry] decided to put one where no theremin has gone before: into a baguette.

The “baguetophone” is a theremin and piezo-percussion instrument inside a hollowed-out baguette.

The “baguetophone” is a theremin and piezo-percussion instrument inside a hollowed-out baguette. Starting with a DIY theremin tutorial from Academy of Media Arts Cologne, [AphexHenry] added some spice with a piezo pickup inside the baguette to function as a percussion instrument. One noted downside of squeezing the instrument into such an unusual enclosure is that the antenna doesn’t respond as well as it might with a more conventional arrangement. Outputs from the piezo and antenna are run through Max/MSP on a computer to turn the bread into a MIDI controller. Like many DIY theremins, it appears that this build neglects the volume antenna, but there’s no reason you couldn’t add one. Maybe disguised as a piece of cheese?

The theremin is popular for its eerie sound output and its non-contact playing style. While they’re typically built using analog hardware, [Linus Åkesson] decided to make one using the venerable Commodore 64.

The instrument works by measuring the capacitance between its two antennas and the Earth. As these capacitances are changed by a human waving their hands around near the respective pitch and volume antennas, the theremin responds by changing the pitch and volume of its output.

In this case, the humble 555 is pressed into service. It runs as an oscillator, with its frequency varying depending on the user’s hand position. There’s one each for pitch and volume, naturally, using a clamp and spoon as antennas. The C64 then reads the frequency the 555s are oscillating at, and then converts these into pitch and volume data to be fed to the SID audio chip.

For those who are not into prog rock in the 70s or old radio shows from the 40s, the Theremin may be an unfamiliar musical instrument. As a purely electronic device, it’s well outside the realm of conventional musical instruments. Two radio antennas detect the position of the musician’s hands to make a unique sound traditionally associated with eeriness or science fiction.

Normally a set of filters and amplifiers are used to build this instrument but this build instead replaces almost everything with a Raspberry Pi Zero 2, and instead of radio antennas to detect the position of the musician’s hands a set of two HC-SR04 distance sensors are used instead. With the processing power available from the Pi, the modernized instrument is able to output MIDI as well which makes this instrument easily able to interface with programs like GarageBand or any other MIDI-capable software.

Many people asked about the progress of our Behremin. While it might have been a bit quiet, our engineers have been working on the first prototype. The team is super excited as we’ll be adding some really cool new functions, never been seen in a Theremin product.
And we’re still targeting 99 USD sales price.
We hope you’re equally excited about this musical instrument:-)
