I came up with this design:
It allows me to change the angle depending on the device etc.
The pager motor can run up to 5V, so I have a circuit with NE555 timer driving a MMBT2222 NPN to drive it.
(much thanks to the Dallas Robotics group website... it proto'd first time on thru hole, and is now being SMD'd at OSHPARK.com)
