The traditional Theremin instrument, which is controlled by the player without any discernible physical contact, uses two antennas and has always been a little tricky to play and master. But a new Optic version, which has been created, offers the same spooky sounds of the original Theremin but uses infrared light to help the player adjust the notes with a little more ease.
Watch the video after the jump to see how easy the Optic Theremin is to play but still creates the unusual sounds.
How the Optical Theremin Works
At the moment, this Optical Theremin created by Chris from Pyro Electro uses IR sensors to detect the distance of the player’s hand and just controls pitch rather than volume and pitch like a traditional Theremin. The use of infrared sensors makes it easier for beginners to get a hang of the instrument, as it provides a more intuitive way to control the pitch.
The traditional Theremin uses two antennas: one for pitch and one for volume. The player moves their hands closer or farther from the antennas to change the sound. This requires a lot of practice and precision. In contrast, the Optical Theremin simplifies this by using infrared light to measure the distance of the player’s hand from the sensor, making it easier to produce the desired notes.
”IR sensors used to detect the distance between the sensor and an object are a perfect fit for a DIY Theremin because they are low cost and they are reliable enough to get the project working. The idea here is that instead of using antennas, we’ll use infrared proximity and be able to play an instrument, the IR Theremin!”
Building Your Own Optical Theremin
If you fancy creating your very own Optical Theremin, Chris has all the details on his site. The project involves using basic electronic components and IR sensors, which are both affordable and easy to find. This makes it an excellent project for DIY enthusiasts and those interested in electronic music instruments.
The Optical Theremin is not just a fun project but also an educational one. It introduces concepts of electronics, sensor technology, and sound synthesis. By building your own, you can learn how different components interact to create music and how sensors can be used in innovative ways.
Moreover, the Optical Theremin can be a stepping stone to more complex projects. Once you understand the basics, you can experiment with adding more features, such as volume control or different types of sensors. This can lead to a deeper understanding of both music and technology.
The Optical Theremin represents a modern twist on a classic instrument, making it more accessible to a new generation of musicians and hobbyists. Whether you’re a seasoned musician looking for a new challenge or a beginner interested in electronic music, the Optical Theremin offers a unique and rewarding experience.
