I've always liked chiming clocks, so I made a pseudo grandfather clock with an RPi Zero W, a $1 I2C servo controller, and a $3 mini digital servo that strikes a long chime tube scavenged from an old doorbell[1] - ntpd means it's a lot more accurate than a pendulum clock, and cron keeps it from ringing in the middle of the night. 1: https://youtu.be/mfOEBCp74UU |
