When you go to a longtime park, then useful rangers have in all probability created well-marked trails and maps so that you can comply with on a stroll by means of nature. However when you stray from the crushed path, climbing and backpacking trails can get slightly dicey. In a perfect world, each path could be mapped with GPS coordinates that hikers may comply with. To get us all slightly nearer to that world, taste_the_code designed this moveable system that makes path mapping straightforward.
This system’s goal is to log GPS waypoints at common intervals because the person walks a path. Once they’re completed, they need to have a pleasant route that they or others can comply with sooner or later utilizing customary GPS navigation. It’s attainable to map a path utilizing one’s telephone and that’s precisely how many individuals do it, however there are a whole lot of the reason why you might not need to depend on a smartphone out within the wilderness. This system is self-contained and consumes comparatively little energy, so it’s a lovely possibility.
An important part here’s a Reyax RYS352A GNSS (World Navigation Satellite tv for pc System) that works with a number of protocols, together with customary GPS. An ESP32 growth board communicates with that module to request and retailer coordinates at set intervals. It then makes use of a microSD card module to save lots of every waypoint for later use. To make the most of the favored TinyGPS++ library, taste_the_code programmed the ESP32 utilizing the Arduino IDE.
These parts mount onto a perfboard with a few standing LEDs and buttons for controlling the logging course of. Energy comes from a USB battery financial institution and the scale of that, together with the waypoint logging interval, will decide how lengthy the system can final between expenses.
To additional enhance issues, taste_the_code plans to optimize the code to make it extra environment friendly and design an enclosure to assist shield the digital parts.
