//it was built earlier itself. nothing much to say. enjoy.

On request from Lumi and others, well let me explain it. The box is from our car. It contained a relay and some  damaged circuit, most probably to control the turning lights. I removed all those things. The linkages, i got some plastic piece(small sheet sort of). As far as i remember, it was from the back cover of old tubelight choke. Heated up the blade of a paper cutter and cut them in shape. They left some black marks. so with an unheated cutter gave the finishing. if you are planning to make one, better use hack-saw cutter, but be careful of the plastic dust. then there are 2 tiny pulleys. The rest, you'll have in your home.

I opened up a brushed motor from toy car. carefully beat it using pliers to move the armature in somewhat middle position. The purpose was to have protruding shaft from 2 sides not just from one side. then it was reassembeled.

Then made the linkage connection as shown in the image. a similar one for the other side but while conecting the pulley to the motor shaft, attached it at 180 degree to earlier one. For making the linkage connection to body smooth, i inserted a pen refill. Then connected the linkage. Connections were made using steel wires.

a 9 v battery and multicolour led came in. but the motor seems to soak up all the pocurrent. I had to use fresh batteries to get it runnung. maybe cell phone batteries would have done it. have a close look at the video.
