This is Steve's second clock (although it's hard to count iterations accurately, with all the experimenting going on). It has hands now, and it is sitting on a shelf about five feet above the floor, so the pendulum can be long (slows it down and runs longer), and the weight can have a long drop (runs longer).
This is Steve's first clock. It had hands, and worked ok, but
only ran for five or ten minutes at a time.
