Modular Music Box – Stepper Motors

While worth buying to test the Adafruit Motor/Stepper/Servo shield and get some hands-on experiments done I suspected the Solarbotics GM17 might not be the best motor for the job(s) in the Modular Music Box – requiring +9V, having little torque at low speed and being quite noisy – though it is quite compact and did just manage to fit centrally in the monome size casing alongside an Arduino Duemilanove clone…

Further research suggested that a stepper motor would be the best choice to drive the sequencer and animation turntables. In the interim I tested a stepper motor from Fab Lab Manchester – the six wire PF35T-48L4 – a 7V (though it will supposedly run as low as 5V) 20ohms UNIPOLAR, S/A 3.6deg stepper motor. The makingthings.com Stepper Motor How-tos helped me identify the yellow and orange as one pair, the black and brown as the other and the red and green wires as the center taps.
