Control lights and sounds with the Arduino-powered LED Eclipse

If you need a MIDI device that can be programmed as your own unique light and sound controller, then Jon Bumstead’s LED Eclipse may be just what you’re looking for.

The circular device, roughly the diameter of a large plate, is constructed out of 30 layers of MDF, and boasts 10 capacitive sensors made with copper strips, as well as 10 corresponding programmable LEDs.

An Arduino Uno powers the assembly, which can be seen being played like a multi-player electronic piano towards the end of the video below. It can also be used as a Simon-style game, and even a light display—though you could program it for any other application you desire!

SMOMID is a Mega-powered MIDI guitar

Nick Demopoulos is a guitarist, sound designer and musician. He is also a Maker and the creator of the “SMOMID” — an Arduino Mega-based MIDI instrument that resembles a touch-sensitive guitar with several joysticks and other sensors. Not only does it just look cool, it can even flash LEDs in sync with the music being played for some wild effects and visual feedback for the performer.

This instrument was created out of necessity because despite the fact that the guitar is the most popular instrument in the world, there are almost no guitar-like midi controllers commercially available. The SMOMID is not a guitar, nor is it a substitute for a guitar, but rather it is a new and unique interface. Like all musical instruments, it has its strengths and weaknesses, and requires patience and practice to master.

Its software allows the performer to control numerous aspects of a performance, including the playing of melodies and harmonies, the direction and pattern of a melody, controlling beats, controlling bass lines, triggering samples, manipulating audio files, and more. All aspects of a performance can be controlled from the grid on the fret board and the buttons on the instrument body. Additionally several custom made synths can be chosen as sounds and several tunings are available. The instrument can be played like a fretted guitar, like a fretless guitar, with twelve notes to the octave, or other variations like twenty four or forty three notes to the octave. In addition to emitting sound, the SMOMID also emits light that is rhythmically in sync with the music the instrument is then creating. The lights also provide visual feedback for a performer that can indicate if an effect is engaged, the rhythm of a delay or the section of a composition among other facets of a performance. The SMOMID connects to any device or software that can receive MIDI information via a USB cable and is bus-powered.
