If you solemnly vow that you are as much as no good, and you occur to spend a lot of of your time in Manhattan below the mid-90s, then you will appreciate this Raspberry Pi-based Manhattan Marauder’s Map.
Not that a Harry Potter-themed map was necessarily [GawkyFuse]’s intent when producing this fascinating build; it’s just that the old-time print of Manhattan — it shows welfare Island in the east River, which was renamed Roosevelt Island in 1971 — lends a great vintage feel to the build. printed on ordinary paper, the map overlays a 64×32-LED matrix, which is driven by a matrix HAT riding atop the Pi 3.
[GawkyFuse] utilizes the OwnTracks app on his and his wife’s iphone to report their places back to CloudMQTT. The Pi subscribes to the broker and updates his place in red and her place in blue as they step about the city; a charming touch is showing a single purple dot when they’re together. There’s no word on what’s displayed when either leaves the map area, however the 2048-pixel screen uses a great deal of possibilities.
We’ve seen a Weasley clock or two around these parts before, however strangely no Marauder’s Maps such as this one. Although this Austrian tram-tracking map comes quite close to [GawkyFuse]’s great design.
