Low power and high efficient display module 18 July 2007

This is a display module for shop demo. I think it is made and design in Japan. Too many this same products in the market, maybe be produced in china. It is very energy saving, compact, light, creatable, put any photo paste in the swing rod and swing almost forever. Now I paste my pet the dog in it.

It use about 1.5V solar cell or battery. very low current consume, very efficient, more than 30 degrees  swing angle. 

Its circuit is also simple. Only using some simple and cheap components. The coil will be trigger and the period of trigger signal is about 20 sec. so one AA size cell can use for a long time.  The coil produce magnetic field to push or pull the permanent magnet that is in rod of swing. After the short energize, the swing rod is swing smoothly and freely, and wait next trigger. 

In the circuit, I think maybe any feedback signal from coil but not sure!
