Mics + motorized motion can create some very unique recording sessions –
This Instructable describes how I made a rotating microphone using just a few basic electronics and some common household items. You can use a rotating microphone to simulate the doppler effect like that of a leslie speaker cabinet. The rotating microphone is the inverse of the rotating leslie speaker. My design is a microphone installed at the center of a lightweight wooden “turntable.” The microphones capsule is connected electrically to the back side of a female 1/4″ TRS connector that is affixed to the turntable. The male end of the Male 1/4″ TRS –> Male XLR adaptor is used as the axis of rotation for the turntable and also functions like a slip ring by maintaining an electronic connection while the female 1/4″ TRS spins around its axis.
