I will be presenting a project that I built "The Chromochord". It is a musical instrument that interacts with a protein (AsLOV2 domain) using light and then uses the predictable and stochastic parts of the chemical reaction to create music. It uses a single wavelength(~5nm bandwidth) spectrophotometer based off the Arduino Due and can read 12 wells in a plate in ~300ms(filtering algorithms and stuff takes time) much faster than any commercial plate reader I could find. I will make the code available later this week after I clean it up for public consumption. I have built two versions an instrument that can be played(with buttons and looping and lots of cool features) and also an instrument that interfaces with software like MAX/MSP for complex musical arrangements. I have been working with a composer Francisco Castillo Trigueros to create some cool music https://www.youtube.com/watch?v=hWzcJpgpyFw
