We lost our friends way too many times while skiing, snowmobiling, snowboarding, and hiking. After experiencing this and hearing about numerous groups getting lost in the backcountry we decided to make a heads-up display to aleviate these trials.
What it does
Uses a compass and GPS to give a real-time augmented layover to show your possition relative to other recreationalists with the BuddyFinder and relative to your starting point or waypoint.
How we built it
Lots of soldering and fighting with GPS and I2C libraries. We created our own addressable LED strip.
Challenges we ran into
GPSD stopped working half way into our project for seemingly no reason. We also had a lot of trouble with I2C libraries for our compass
Accomplishments that we're proud of
The form factor of our prototype is satisfying along with the functionality of the LEDs
What we learned
We learnt lots about soldering and using I2C
What's next for BuddyFinder
Finding a cheaper and possibly simpler implementation
