Joe Grand Pizza Compass
Joe Grand wanted to build something that could help him locate pizza shops around the world, whether it be in New York City or the cobblestone streets of Sicily, Italy. This sounds like a daunting task, but it only took the inventor 3-weeks to complete, which basically consists of a handheld PCB, Particle Boron LTE CAT-M1 (cellular endpoint), GlobalTop PA6H GPS module, a LSM303DLHC compass, and eight NeoPixel LEDs. Read more to see how he built it and how the device locates pizza.



To activate its pizza finding capabilities, simply press the power button and walk around, keeping the top-most LED illuminated. This occurs because the cellular endpoint is pulling down the coordinates of the nearest pizza establishment from a Google API, and then compares that data to the user’s current GPS location. However, it can also be reprogrammed to work with just about any other establishment, from washrooms to hiking trails.
