Sometimes when I go cycling I take a buddy or two and we sometimes get split, and i was thinking that having something to tell me how distant we were from each other would be cool. Yeah, there are apps that do that, but they arent foss, they send your location to who knows where, and they massively drain your battery. I saw that there are some varriants of lilygo devices with gps and a screen, but how practical are they really? How fast do they update? How is the battery? Is somewhere using them for a use case similar to this one?
Did you go with this? It’s a really cool use-case.
Sorry! I didnt see your comment until now. I’ll copy paste what I’ve written to the other user:
I’ve bought two nodes and attached some gps i had lying around, works pretty good for a proof of concept. It’s kinda slow to update the positions tho, but the biggest drawback is that yoy need to have the app open to see anything because the oled screens are very very unreadable under the direct sun.
