Suggestions for small motors for an art project?
What I'm thinking is something similar to a clock that will spin 3-4 roundish cast paper layers (one nests inside the other) on the same axis but at different speeds and maybe different directions. Initially I had thought about using small battery operated clocks but I need something with more options.
Each layer will be lightweight (made of paper) and the speeds will be relatively slow.
Since I may need about 30 of them I'd prefer them to be inexpensive. And, since I'm new to this area of knowledge I need them to be relatively simple.
Grateful for any suggestions! Thank you in advance.
