1. Do you know of any rotatory motor that I can build myself? A motor that can support a cylinder of weight about 2-3kilograms, and it would be best if the speed can be adjustable. Major plus if I do not need to use a lot of money.
2. If you have made great big art structures before, can I please speak to you? I really need help with my art project because 1. it's driving me nuts and I have about 4 more months to finish EVERYTHING and 2. one of my teachers keep on saying that it wouldn't work.
