Owl theremin

August 5, 2013 · Posted in Uncategorized 

The theremin control voltage outputs can be used to play the synth in the background. The theremin is in fact an excellent PAiA Theremax, the same as used for the Badgermin. The owl rests on a sliding carriage, which can slide along four vertical bars fixed inside the log. When the motor is turned on a winch mechanism winds a length of sash cord, which loops over the top of a second pulley, which in turn lifts up the sliding carriage. When the carriage reaches the top, a limit switch is automatically pressed, switching off the motor. For the owl to descend, the owl activation switch is flipped once more, reversing the polarity of the motor, allowing the carriage to be lowered down onto another limit switch. The antennae disconnect for ease of transportation, and the lower half of the stand can be unbolted.
