Volunteers for Build Your Own Internet Workshop @OmniCommons 27 Jan 2-5pm

by grant＠peoplesopen.net

Hey disaster.radio peoples! Some of you maybe unaware, but SudoMesh/PeoplesOpen is hosting another Build Your Own Internet (BYOI) Workshop on Saturday, Jan 27th 2-5pm at the Omni Commons. We've planned for disaster.radio to have table at the event. I was hoping to confirm a few willing volunteers to work to the table and talk to people about the project. We're expecting to have almost 100 people in attendance, so we'll need all the help we can get. I will be at the event, but may be busy with other organizational tasks and plan on working a table for buildyourowninter.net (http://buildyourowninter.net). I'm hoping to prepare stuff for the disaster.radio table this Monday night at Sudoroom. I'm hoping to have a working demo of the chat app running during the workshop. It still needs to be tested, but we could "hide" some of the disaster.radio prototypes around the Omni Ballroom, so people could connect to them and broadcast a message to all the other disaster.nodes. In the event that the prototypes are not ready, we can show the simulated chat app or maybe the network simulator that Juul has been hacking on. If anyone is interested in volunteering or helping prepare, feel free to respond to this thread or email me directly. Stuff we may need: * An extra projector * An open computer to connect to projector * More working disaster.radio prototypes? (I currently have 4 working prototypes, not sure how many more we have parts for) * Rando electronics parts/equipment to layout on the table * More stickers printed and cut (some designs can be found https://github.com/sudomesh/propaganda/tree/master/stickers) * A short blurb about the project for the event program (I'm currently using a sentence or two from the website) Anyway, hope to see some of you at the workshop. More info about the workshop can be found at peoplesopen.net/workshop (https://peoplesopen.net/workshop). Thanks, grant_____/@paidforby Sent via Migadu.com, world's easiest email hosting

Using ESP32 WiFi mesh as local 'backbone' of preference?

by samuk＠disroot.org

So thinking about the limitations of mesh networks in general, and wondering how your LoRa network would scale. I'm guessing that in common with WiFi mesh reducing the traffic would help, particularly if you ended up with a fairly high node density and a well-used & congested network. So I was wondering if it would be possible to pass off local traffic to a WiFi mesh? (Run on the same hardware) So if I want to communicate with my neighbour two streets away it goes over WiFi, if it's someone on the other side of town it would go over LoRa? In this implementation: https://gitlab.com/BlackEdder/painlessMesh/wikis/home "painlessMesh does not create a TCP/IP network of nodes. Rather each of the nodes is uniquely identified by its 32bit chipId which is retrieved from the esp8266/esp32 using the system_get_chip_id() call in the SDK. Every node will have a unique number. Messages can either be broadcast to all of the nodes on the mesh, or sent specifically to an individual node which is identified by its `nodeId." So could the node could look in its list of connections: https://gitlab.com/BlackEdder/painlessMesh/wikis/home If it has a route over WiFi then send the packet that way, if there is no route over WiFi (Or it's more than X hops away) then broadcast it over the LoRa interface instead. I'm guessing this long range mode is incompatible with the 'Painless mesh' but it could be interesting to look at that too. https://blog.honzamrazek.cz/2017/08/testing-the-wifi-range-of-esp32/ I guess using wifi & LoRa would have power implications? Thanks Sam

ESP32 & LoRa SX1278 fully soldered from $10

by samuk＠disroot.org

I was wondering if you'd seen these boards? https://www.aliexpress.com/wholesale?catId=0&initiative_id=SB_2017123102135… It's a SX1278 all soldered together on a ESP32 board for about $10 Would your software run on it? Or would it be a lot of work to port? https://www.cnx-software.com/2016/03/25/esp8266-and-esp32-differences-in-on… Someone has done chat over it: https://hackaday.io/project/27817-lora-chat There is some info here: https://hackaday.io/project/27791-esp32-lora-oled-module I might order a couple to play with Thanks Sam
