About this model

Da Vinci challenged the public with a number of perpetual motion machines and he tricked many people with them. In reality, the sum of distances and weights of all the moving parts is zero. No energy will be generated. Da Vincy did not have acces to geared micro dc motors. He surely would have used them to make his machines even more convincing. A microswich is actuated when the unit is placed on the table. So, like in the video, lift the unit and place the four (17mm) marbles.
