This is a demo of my Optical Scanner triggering a midi note each time a black object passes underneath.I mounted the scanning device on my turntable and use a white platter as a surface. In this demo I control a virtual drummachine with the midi output of the scanner. First part of the video shows the setup of the trigger threshold to the current ambient lighting conditions, then the usage with the black trigger dots. The whole project is realized on a PIC16F88 microcontroller and the full documentation as well as the code can be found at: www.obsoletetechnology.wordpress.com (for non-commercial use only)" [link to post for the archives]
