Read in Principles for Designing Computer Music Controllers, the Nukulele is a nice modified ukulele!
The Nukelele (thanks to Michael Brooke for the name) was constructed in Bob Adams’ Interval Research Expressions project. While collaborating on other Expressions projects such as “the Stick” and the “ Porkophone,” the Nukelele was a personal experiment to design, implement, and test a new controller as rapidly as possible. The Nukelele was intended to match the expressiveness of a true stringed instrument, by using audio directly from a sensor to drive a plucked string physical model. Two sandwiched linear force sensing resistors under the right hand served to provide pluck/strike position information, along with the audio excitation for the string model.
