Surely many of the habra-people have already seen the model of "The most useless device." Who does not remember, this wonderful device looks like this:
Usually you want to try to do such entertaining things yourself ...
The circuit of such a device can be quite simple:
I used an ordinary model servo as an engine, removing the electronics from it and finalizing it to a constant rotation mode. The most difficult thing was with the case. Since I did not want to spend too much time on the venture, I decided to mold it from thermoplastic, it turned out to be quite practical and simple.
Although of course my device does not have such a sophisticated look and the “finger” does not come out of the box, but it works and helps to relax throughout the day.
