Time for the results.
While the topic has been pretty active we only have 3 competitors:
3th place goes to markman scoring 2364 going round the box twice with timed compressed rubber. That turned out te be way too expensive to be competitive. Thanks for sending it in!
2nd place is for KuzyaHG scoring 6930 going round the box 5 times with a very clean spinner combined with a good cheap timing mechanism. I actually thought you were going to be the winner but...
1st place is for bythelee scoring 8016 going round the box 8 times with a washingmachine I really didn't think you would get that much rotations out of it but you sure did deliver in the end! Congrats.
For a poc i made a reusable pulley with a couple of weights to operate the structure.
When you guys started talking about perpetual motion i decided to give it a try. After all a well balanced spinner only needs a minimal amount of force to rotate. It had to work....
And it did. Right click the slow-button to make it go a bit faster because its horribly slow.
Thanks for playing and hope to see you in the next
Edit: changed bythelee's score because I missed his best solution
