This article describes the theory, construction, and final project functionality of a musical circular harp that utilizes an off-the-shelf concert organ which provides 160 possible instrument sounds and full MIDI capability. Plus, it looks really neat.
The last few years have seen a massive resurgence in the popularity and availability of voltage-controlled synthesizers. The very simple ribbon controller we’ll construct in this article will be used to control any of the myriad voltage-controlled modulation opportunities provided by the typical voltage-controlled synth.
The Lunch Box Jukebox is a compilation of various projects to make a compact portable music, video, and game entertainment device with the Raspberry Pi Zero at the heart of the Jukebox Internet radio.
In my previous Theremin article, I described the first of my laser Theremin projects: the LASERVox. This is a simple-to-construct Theremin-like device that acts as a MIDI controller for a synthesizer. In that article, I discussed the possibility of a more analog style laser Theremin that has its own built-in synthesizer or pitch generator. That’s the topic of this article! We’ll build the FLiPVox: a continuous pitch laser Theremin with its own mini synthesizer.
The Theremin, invented by Leon Theremin (Lev Termen) in Russia in October 1920, was one of the first electronic musical instruments. It’s also the very first instrument of any type that you play without touching it in any way. An expert Thereminist can play as expressively as a violinist or cellist. If you want an instrument with violin levels of sensitivity, then a regular Theremin is for you. If you want an instrument that’s easier to play and that can control your MIDI synthesizer, then that is precisely what the LASERVox offers. The LASERVox is a perfect project for the novice because it’s a real instrument that can be built very easily with just a handful of components.
The complexity and sophistication of the electronic hardware required to recover composite baseband signals in the FM band is beyond the capability of most experimenters. However, modern digital signal processing software, capable PCs, and inexpensive software defined radio (SDR) hardware can now be easily combined to receive the information in these broadcasts. Learn how to combine this hardware, software, and your PC to build SDRs to receive FM radio broadcasts and more.
As a final class project for our “Digital Systems Design Using Microcontrollers” course we all took last semester at Cornell University, we created a very unique device. We wanted to design something fun, aesthetically pleasing, and interactive, and since we all enjoy listening to music, we decided on a music visualizer. Our vision was to create a unit that listens to music being played, then in real time displays a dynamic and colorful visual representation of the music based on the volume and pitch of the notes. Additionally, our music visualizer provides an alternate avenue for experiencing music for the hearing impaired. Here’s how we did it, so you can make one too!
