I am a hiker/trail runner myself; often times I wish I had a sort of "personal assistant" to guide me while in the wild, either for safety or just to push my limits or find new places. This haD project is all about that: a Raspberry Pi Zero-based wearable way-finding device, featuring a handful of sensors to help me navigate (GPS, accelerometer, pressure sensor), show me the data on demand (LCD display) and stay up to date with trail maps and safety info (wifi).
The idea is to use wifi connection to fill the wearable with data prior to hitting the trail (therefor while still at home); then use the GPS and all other sensors to track my way, log all this data to a SDcard; and finally gather all data when back home and be able to analize it to improve my performance and/or share valuable insights to fellow hikers/runners.
