I am interested in learning about spring powered mechanical items and possibly making a spring-powered fish feeder. My initial design is, a mechanical spoon would start at the top of a circle, then slowly rotate to the 6pm position where the fish food would dump into the tank after about 4 hours.
Anyone have any links of that sort?
Is there a lego Mindstorm set that has spring-powered contraptions? My point is not to use electricity or batteries of any kind.
Well...a moustrap is a spring. Now how do I slow it down? I assume I need gears and such.
