Lego Pendulum Clock

This is my new Lego Pendulum Clock that&fully functional. It has both minute and hour hand which can be adjusted to set the time right. The pendulum is set to swing once per second. The weight can be winded up again with either a key or a motor. I&working on making a auto-winding mech so that you wont need to wind it up yourself. The weight weighs about 2 kg. I&also build a differential so that the pendulum can swing simultaneously as the weight is being winded up.
