Digital Weasley Clock: Muggle Magic
Back in 2009, we checked out a real-world version of the Weasley’s locating clock. Redditor tbornottb3 recently made his take on the time– er spacepiece, but instead of mechanical hands he used an LED strip.
The clock is powered by the Particle Photon, which gets data from the smartphones of tbornottb3 and his relatives via the powerful app If This Then That.
