A Harry Potter fan constructed a working replica of the clock that the Weasley family members used to track each others’ locations. Imgur user tbornottb shared photos of the custom clock, designed after the ones featured in the films, that he built to help his parents keep track of him and his other family members. Tbornottb used a gutted broken clock that he purchased from an antique store as the base and had a friend illustrate the new face of the clock, which featured locations such as on the way, home, work, holiday, forest and mortal peril.
He then used a Particle Photon that would communicate with an application known as “If This Then That” that would move the clock’s hand depending on each family members GPS location. Each family member then set the parameters for what each geographical location would be represented by on the clock.
“Most of the rules are location-based (setting me to WORK if I enter my university library, HOME if I enter my dorm), but you can set other triggers too (set me to HOLIDAY if the forecast calls for snow, set me to MORTAL PERIL if the stock of the company I’ll be working for next year drops too low),” tbornottb wrote.
The final touch was a letter “B” which represents his family name and glows a different color each time a family member changes location.
