Toy with balls, made of cardboard (Marble machine)
This toy is also called "elevator for balls".
Made a toy like a lift for balls or as it is also called the "perpetuum mobile". Further in the article we look at the pictures and video of the toy in action.
The design was done without any drawings and without a ruler, so the balls in some places get stuck, and the gear wheel itself refuses to turn, all these shortcomings will be taken into account in the following toys.
Several photos of toys from different sides.

I made this CNC machine myself in 2015, videos of the same year. For a long time I was asked to make a video on the assembly of this machine, later my hard drive broke, by some miracle I found some materials on this machine on another medium. After almost 4 years I will publish the materials, as I did with my own hands a CNC machine tool from the available materials.
I made this powerful lawnmower myself for the village, there is always a lot of high grass, which is not rational to fight with the usual manual trimmer. This animal mows down everything, tough grass, small trees, levels of hills, covered with moles, and even turns old bricks out of the ground.
