What Hacker News says
3 sourcesHey there! I am the current maintainer of the disaster radio firmware https://github.com/sudomesh/disaster-radio/ and the LoRaLayer2 routing protocol https://github.com/sudomesh/LoRaLayer2/ that is intended to mesh disaster radio nodes. The website doesn't include many of our latest developments, if you would like to stay in the loop, it's best to join our mailing list https://sudoroom.org/lists/listinfo/disasterradio or follow our wiki where I am posting development updates https://github.com/sudomesh/disaster-radio/wiki
Happy to answer questions as I am capable.
It's cool to see this up on the front page, thanks for all the interest!
In Disaster.radio: a disaster-resilient communications network powered by the sunI am the current maintain of the firmware for this project. Recently, I've been doing development for it using the LILYGO TTGO ESP32 dev board (V2.1_1.6)
https://www.aliexpress.com/item/32915894264.html?spm=a2g0o.p...
Therefore, power consumption specs should be similar to this board.
We are working on a new board design with an integrated solar panel and two LoRa radios, but I am less involved in that part of the project, so I can't answer all your questions on the power system. Perhaps this link will help, though it has not been updated for the ESP32, https://github.com/sudomesh/disaster-radio/wiki/Power
Currently, it does not have a sleep mode, I recall there being some concerns with waking up from sleep mode back when I was dev'ing with the ESP8266, not sure if that has changed on ESP32, have not re-approached the idea it since switch

ing to ESP32.
We did have some do some tests with an off-the-shelf 15W solar panel and a super-cap, it seemed to work well. Check out their report, https://sudoroom.org/pipermail/disasterradio/2019-December/0...
