Vivisection # 2- Halloween hand

The last couple of days i carried out the hand vivisection. The hand is another toy made from Gemmy industries, creating simple movements to appear 'alive' and creepy.






After getting the 'skin' off, i noticed a simple layout of the mechanics, one motor driving a gear box that displaces movement to the 'fingers and to the underside of the wrist: oval wheels to help with movement.

Once the frame has been separated from the gear box, the remaining entity resembles a bug of some kind, with attennae pulling itself across a table.





The motion sensor is what i am currently working on. I had some troubled removing it and then noticed that the motion sensor has less sensitivity when out of its 'hole. Perhaps the cylindrical enclosure creates shadows which the sensor reacts to.
