Pat Peters from Omaha, Nebraska has taken inspiration from the Wizarding World’s famous Weasley Clock and built his own Internet of Things clock, using a Raspberry Pi (a B+ in this case). Tracking the locations of both himself and his wife, the clock’s Pi subscribes to an MQTT broker service that their phones publish events to using the OwnTracks GPS app. Added into the mix is an Adafruit ServoHAT and some servos to move the hands. He has published how to do it on an Instructable, so you can have your very own clock!
Thanks to the Foundation’s Alex Bate for spotting this one.
