Here is my source of air or as the organ folks say, wind. I couldn’t afford a real organ blower so I went with the Shop-Vac solution. I built this box to accomplish two things. First, one could hardly hear the organ over the roar of the Shop-Vac so I needed to do something about the noise. Second, the higher the pressure in the organ the higher the pitch of the pipes. Therefore, a pressure regulator is needed to limit the changes in pressure that occur as different numbers of pipes are playing at one time. The lower box contains the Shop-Vac and muffles its noise. The upper box further muffles the noise and regulates the pressure.
Each Friday is PiDay here at Adafruit! Be sure to check out our posts, tutorials and new Raspberry Pi related products. Adafruit has the largest and best selection of Raspberry Pi accessories and all the code & tutorials to get you up and running in no time!
Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
