No...i know wilf came up with an experimental circuit for a head popper...i
tried it but it didnt work like all my other robots =)..so it might have just
been me. If wilf doesnt come up with something new (no preasure here now =)
then im sure i can dig up that circuit somewhere

just how efficient are pager motors?
i assumed because they were small, they must be pretty efficient, but i
think i assumed wrong.
I was using a "PM" for the test motor on my Solar PSHead, and could never
get it to fire. Most of the folks who have PSHEads werking are using
BGMicro lens motors. So i'm beginning to look at my pager motors accuisingly!
