[Davy] and his friend [Chris] were tasked with putting together a bachelor party for their friend [J], and had a little more in mind than the standard drunken revelry. To earn the privilege of partying his brains out, they decided that [J] would have to fulfill a series of tasks and challenges before joining up with the rest of his friends for the evening’s events. [Davy] didn’t specify what these tasks were, lest he spoil the surprise, but he did let us in on a little device that he and [Chris] built to help guide the bachelor through his day.

They were a bit worried that the bachelor would get sidetracked during his journey if he happened to imbibe along the way, so they built a device called jGPX that would ensure [J] stayed on track and on time. jGPX is a custom GPS navigator consisting of an Arduino, a GPS module with built-in antenna, and a compass.  The pair created a set of routes in Google Earth, exporting the data to KML for interpretation by their device. The jGPX is meant to guide [J] along via a small LCD screen that shows him the distance to his target as well as the proper direction of travel to get there.

It looks like [J’s] friends put a lot of effort into his party, and although there are no details as to how things went, we’re sure it was a blast!
