Weasley Clock based on a Raspberry Pi brings a little Harry Potter magic to a household

Here’s a lovely Harry Potter-related project from someone who prefers to be anonymous but whose handle is “RandomString”. It’s a Weasley location clock built into a grandfather clock. The whole system uses Home Assistant which is a piece of software which reads in the location of the family’s mobile phones which have Life360 installed on them. Updates are sent from Home Assistant to a Raspberry Pi using MQTT and the clock then turns the relevant clock hand to indicate the location of the individual.

The Pi is fitted with an Adafruit 16-channel Raspberry Pi Servo HAT (that’s Adafruit. The Pi Hut also sells them) and servos are used to move the hands. You can see all the code and build notes for the project on GitHub and you can read more on the maker’s blog here. There’s even a photo gallery of the build and how it all fits together!

We’ve seen Potter projects before, but I think this one is, perhaps, the classiest.
