[psymansays] needed a panning head for his robotics projects. already being familiar with the NXP LPC2148 from work, so he wished to utilize that to manage it. he developed his own carousel out of old CDs. The axle of the carousel is a potentiometer. This is what he’s utilizing to determine position. The gear motor was really cobbled together with bits from a windup toy as well as an old motor. This may be a bit bulky, however it seems not only functional, however relatively versatile.
