The Krahôs are a sovereign people that inhabit the savannas of Brazil. Most of their villages are isolated without electricity or any form of communication. During the pandemic communicating with each other has become crucial to saving lives.
43,2Km with 5 repeaters
Together with them we’re planning on creating the above mesh using Heltec Lora devices, connected to 10W panels and battery, as relay nodes placed on strategic hilltops. In the villages people will connect T-Beams to phones to send messages using the Android app.
- 5x Heltec Lora
- 5x 10W panels
- 2x T-Beams
- 5x waterproof cases
- 7x 18650 batteries 2200mah
- 7x 915mhz moxon antenas
These were chosen because of the availability in Brazil, without having to wait for stuff from China. Unforunately the moxon antenas aren’t available here, so would have to either find a place to 3D print them or wait…
- Is this realistic?
- What challenges should we forsee?
- Are the hardwares in the kit good choices?
- Are we forgetting any other hardware?
Any support is really welcome
