Imagine a world where strings dance to the rhythm of solenoids, where motors create melodies, and coils weave a tapestry of infinite sustain. This is the world of Greg’s Harp, a robotic string instrument that pushes the boundaries of musical innovation.
Greg’s Harp: A Masterpiece of Mechanical Harmony
Crafted by the ingenious mind of Frank Piesik, Greg’s Harp is not just an instrument; it’s a symphony of mechanics and artistry. Its unique sound and captivating design have captured the attention of music enthusiasts worldwide.
The Mechanics Behind the Magic
At the heart of Greg’s Harp lies a pair of iRobota Nano boards and a Teensy 3.2, the brains that orchestrate this mechanical masterpiece. Notes are selected by an array of 12 servos, four for each string, using an ingenious loop mechanism.
Striking the Strings: A Delicate Dance of Solenoids and Motors
Greg’s Harp is played by a solenoid-driven “KickUp” device, a mechanical marvel that gently hits the strings from below, coaxing forth enchanting melodies. Accompanying this is a small motor that continuously swipes with a “tape-propeller,” adding a layer of ethereal texture to the music.
Infinite Sustain: A Symphony of Unending Notes
One of the most remarkable features of Greg’s Harp is its infinite sustain. A coil assembly, a testament to engineering brilliance, provides a continuous flow of energy to the strings, allowing notes to ring for as long as desired. This opens up a world of possibilities for creating haunting soundscapes and mesmerizing sonic textures.
