On this musical instrument, the player can produce different pitches by sliding a vibrating metal rod back and forth. Vibrations in the rod are initiated at resonance frequencies corresponding to the length of the rod. A pickup coil similar to an electric guitar pickup converts the mechanical vibrations to an electrical signal, which is then amplified in voltage using a preamp and in current using a power amp.. The power amplifier gives feedback to the driver coil so the instrument's vibrations can be sustained. This is a project proposed by Skot Wiedmann.

Laser Harp MIDI Controller with Musical Articulations

Featured Project

Electronic music concerts usually need eye-catching visual aids to create a certain atmosphere. Laser musical instruments is a great way to do this. We have been thinking of this project for a while and it was ECE445 that made this laser harp come true. The novelty of this project is that the harp-like laser device mainly focuses on playing articulations with laser and sensors, as a true universal MIDI controller, to control timbres that are synthesized or sampled. Articulations include piano/forte, vibrato, tremolo, and portamento. With the help of Professors and TAs, we learned how to pick right the components, design PCB, soldering, and program microcontroller. Those skills are not only useful in this class but also really important to electrical engineers. Also, we learned how to use individual strengths, combined with effective teamwork, in the pursuit of meaningful goals.
