[btbuildem]

I've been futzing about with a vague prototype of a backcountry comms device (esp32, lora radio, gps) and initially was going to pair it via bt to a phone, for the use of screen / browser / keyboard. Long story short, small e-ink displays work really well in daylight, and blackberry keyboards (and other tiny form factor ones) can be got off ali[baba|express] for relatively cheap.

It doesn't take much to throw in a LTE modem, sim card reader, a mic and a speaker -- suddenly you have a phone!

I'm don't really have a point here, and I don't know exactly where my meandering project will eventually end up -- but I really like the "own the full stack" aspect of it, and the decoupling of my little device from all the extras that have accumulated under the umbrella of "phone".
