The organ has 42\u00a0wooden pipes (representing 3.5 chromatic octaves). Each wooden pipe is different and had to be custom-cut to play the right note. A &#8220;blower&#8221; used to cool data centres was modified to keep it quiet\u00a0and enclosed; air pressure from the blower feeds the organ&#8217;s wind chest which provides the air for the pipes. The valves for the pipes (which cause them to &#8216;play&#8217;) are opened and closed using solenoids. The main processor is a Raspberry Pi which provides a user interface for selecting songs and sends MIDI instructions to an Arduino Due which has a pin assigned for each pipe. A transistor board boosts the activation signal so that the solenoids fire. It certainly makes a beautiful sound in full flow. You can see it in action in the video above, which features an interview with Wendell, and you can <a href=\"http:\/\/wakrec.blogspot.co.uk\/\" target=\"_blank\">read more about the build over on his blog<\/a>.<\/p>\n<p>&nbsp;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Wendell Kapustiak has built a self-playing wooden pipe organ.
