This sounds like a very interesting project indeed! You should report back if you succeed with this. You need to connect the weight of the base to the pendulum. How are you going to do that? You can have gear racks each side of the platform, connect them to gears on the base and let the gears drive the pendulum. That shouldn't impose too much friction, I'd say. Or you can hang the platform using chain links. This should be better friction-wise, but that may be a bit involved to build. Fredrik

		Re: Any ideas on how to do this with Technic?
I've received some very good responses here. Jacob Andersen's worm gear idea is what I would do if I were to use a motor, but since gravity already provides energy for the system, a good engineering solution would not use an additional motor. Plus, (...) (25 years ago, 30-Nov-99, to lugnet.technic, lugnet.adventurers)
