Laser Guitar is a device which prototype was presented in University of Wisconsin - Madison Engineering Expo '99 (April 16  - 18, 1999) that is attempting to digitize an acoustic guitar. The team members working in the project are (in alphabetical order):

1. Adam Adjiwibawa - Hardware Engineer
2. Franciscus Handiono - Software Engineer
3. Soeryanto Sutrisno - Technician

The show in the expo itself was a huge success. We were awarded the second place in the "Small Group Exhibit" ($750 dollars prize) and the exhibit attracted a lot of people. Dang it, we werejust few pts from the first one. And the best part, no one got their hands burned by the laser (hehe... j/k, lasers used are only 0.5W). The judges for the competition, 8 total, were not only local professors, but also real engineers from various big companies, such as General Electrics and General Motors.

How you would play the guitar is pretty similar to how you would play real guitar. The left hand will control what kind of notes you want to play and the right hand will pluck the laser to actually play the note or not. What kind of note or instrument is assigned to each button is software controlled. And if you push the several buttons in one column, only the lower one will be in effect.
