Cool projects are rare. Here I found one I want to show to you. An off-grid personal communicator. It includes a lot of new technologies: ESP32, Smartphones, LoRa, BLE, GPS, Mesh, and as you see, 3D printing. And it solves a problem that could be seen as a human right: Personal SMS style communication everywhere in the world, without the need for any infrastructure, and without mass surveillance. In addition, it shows the location of all your friends in your group on a map on your Smartphone. Everything open source, of course. How cool is that? Even "Sexycyborg" Naomi Wu likes it.
