OMI Arduino Motor Workshop

Here’s a quick video from last Friday afternoon’s OMI workshop, where we looked into using an arduino/Teensy microcontroller to drive a stepper motor.  We found that using one of the external libraries (AccelStepper), you can control the speed of the motor in steps/second, which corresponds to the frequency of the audible sound that the motor generates as it turns.  This sound can be acoustically amplified by holding the motor up against something that resonates - like the top of a desk or an acoustic guitar body - or electromagnetically using a guitar pickup or telephone tap.

Acoustics and Instrument Building - Round II

MUSI 371 / ENAS 344 Musical Acoustics and Instrument Design is back in full swing for the spring 2016 semester.  In case you missed us last time, here are links to an article and video describing the concept behind the class:

Musical Acoustics and Instrument Building

We are offering a new course this semester in musical acoustics and instrument design, ENAS 344/MUSI 371.

The class meets in the Center for Engineering Innovation and Design (CEID), and is being co-taught by myself and Larry Wilen, from Engineering and Applied Science.

Check out the course website for more information!
