Peg Clock

thingiverse

This innovative clock design features twelve pegs on its top for time-telling or an LCD screen for precise readings. A hidden belt with a bump moves under the pegs, raising them in 12 hours; another 12 hours later, it goes from right to left. To interpret the time, if it's AM, the second peg from the left denotes 2 AM, while in PM, the second peg on the left signifies 10 PM. Images are available for better understanding. The clock is built using a MakerBot and plastic materials; an Arduino controls the time with an external device for enhanced precision. A motor rotates once per hour for 12 hours in one direction, then reverses for another 12 hours. For higher accuracy, connect a full-turn potentiometer to the motor's output, allowing the controller to calculate and adjust speed accordingly.
