These are definitely a rare find. Ever wonder what Mark Tilden used to build his original BEAM devices out of? These things! (His original Photovore, T.H.A.B. jumper, and SunSpinner)! These are high-precision tape transport mechanisms with 2 motors - one large pancake motor, and one worm-reduction gearmotor!


They also have quite a variety of belts & screws, a beautiful brass pulley wheel, rubber capstan pinch roller, a fine spring (what the original "omni-touch" tactile sensors were built with), and a fine coil (pancake motor encoder output).


The Pancake Motor statistics:


  • Initial rotation at 0.2V, drawing 15mA @ ~120rpm
  • 2.0V draws 23.7mA
  • 5.0V draws 36.7mA
  • Motor Coil Resistance: 6.1ohms

The Wormdrive Gearmotor statistics:


  • Initial rotation at 0.3V, drawing 23.5mA @? 20rpm
  • 2.0V draws 31.4ma @ 192 rpm
  • 5.0V draws 46mA @ 526 rpm
  • Motor Coil Resistance: 5.7ohms

These are simply excellent for hacking into custom BEAM devices.
