Off the Grid Messenger Off The Grid (OTG) Messenger is an easy way for people to communicate through text messages when in remote areas. With a theoretical transmission range of 10 miles (16kms), OTG messenger can be used by groups of people to stay connected when they are in areas not serviced by mobile connectivity. For portability and low power purposes, the device was created by re-purposing an old Nokia e63 phone I had laying around. The enclosure, LCD, keypad, backlighting and speaker have been re-used however the motherboard was re-designed from the ground up with low power components, a modern STM32 H7 microcontroller, an ISM LoRA radio and expanded flash memory. https://github.com/TrevorAttema/OTGMessenger Comments https://news.ycombinator.com/item?id=27659105 #otg#offthegrid#grid#im#messenger#alternatives#cellphone#mobile#nokia
