Fwd: [sudo-discuss] diaster.radio modulation scheme tests

by Jenny Ryan

hey adam, this is rad! fyi there's also a disaster.radio mailing list (fwd'ing) ---------- Forwarded message --------- From: Adam <me(a)adammunich.com> Date: Wed, Apr 25, 2018, 21:39 Subject: [sudo-discuss] diaster.radio modulation scheme tests To: Sudo room <sudo-discuss(a)lists.sudoroom.org> Hi all, I ran some tests on LORA modulation schemes to get the best results I could on a 100mW TX power budget. I nearly ran out of gas during this latest test, and unfortunately I managed to screw up my data logging, so I don't have RSSI or SNR data, but this map contains all the places I stopped and got a two way signal on my jet ski. The transmitter was in my hand, the receiver was at pier 50, SF. DIY half wave dipoles were used, with a center freq of 900MHz with a +/- 100MHz 3db roll off. https://www.google.com/maps/d/u/0/edit?mid=1dE2QZS9cgX_oHLWyzmUNAYrjlbX0wJp… I found that quarter wave antennas are no good (see the red markers). The blue markers are today's test, using RFM95's from HopeRF. To get the very long range, I used the following modulation scheme using the RadioHead library. RH_RF95::ModemConfig modem_config = { /*Reg 0x1D: BW=125kHz, Coding=4/8, Header=explicit*/ (7 << 4) | (4 << 1) | (0), /*Reg 0x1E: Spread=4096chips/symbol, CRC=enable*/ (12 << 4) | (1 << 2), /*Reg 0x26: LowDataRate=On, Agc=On*/ (1 << 3) | (1 << 2) }; RF95.setModemRegisters(&modem_config); In other news, you can still jet ski if your core body temp is 88F. Little unpleasant though. - - - - Begin automatically generated footer - - - - I seek to understand, and aim to create.

Job Opportunity

by Max Morrison

Hey all, I went to meetings a couple months ago but life got in the way. I started a new job around that time and it was hectic for a minute. New job is hiring more people though! FreeWire is hiring an embedded systems / controls engineer, and I figured this would be a great place to find sharp folks trying to make a real difference in the world! We make a mobile electric vehicle charger and we hope it will accelerate the adoption of these vehicles. Job description: https://angel.co/freewire/jobs/245142-controls-engineer. Please feel free to reach out if it looks interesting to you. Cheers, Max

Fwd: [Mozilla/NSF-WINS] Stage 1 winners and Stage 2 instructions

by Jenny Ryan

People's Open Network has received an Honorable Mention for the Smart Community Networks Challenge! Both PON and Disaster Radio have been chosen to move onto Stage 2 of the Challenge. Great work, team! -- Jenny Ryan People's Open Network <https://peoplesopen.net> *Building a community-owned and -operated wireless network in Oakland, California!* ---------- Forwarded message ---------- From: Mehan Jayasuriya <mehan(a)mozillafoundation.org> Date: Tue, Feb 20, 2018 at 1:06 PM Subject: [Mozilla/NSF-WINS] Stage 1 winners and Stage 2 instructions To: Mehan Jayasuriya <wirelesschallenge(a)mozillafoundation.org> Hello, This morning, we announced the 20 teams that were chosen for awards during Stage 1 of the NSF-WINS Challenges. You can view all of the winning projects, as well as profiles of our judges, on the NSF-WINS website <https://wirelesschallenge.mozilla.org/>. If you’re receiving this email, your team has been selected to move on to Stage 2 of the Challenges. We’re experiencing an issue where some teams did not receive notification of their status via email; please find a copy of the Stage 2 notification letter attached to this email. If you have any additional questions about your application status, please let us know. What’s Next? The WINS Stage 2 application is now available via the Fluxx portal. Simply log into Fluxx using your existing credentials in order to fill out the application. Please see the application guide for a full set of instructions on how to fill out the Stage 2 application <https://wirelesschallenge.mozilla.org/_assets/NSF.WINS.application.guide.pdf>. Please make sure you’re using the latest version of the guide (v1.3, February 2018), as some of the Stage 2 application questions have changed since the previous version. Your Stage 2 application is due by June 22nd. What Will the Judges Be Looking for in Stage 2? The goal of Stage 2 of the Challenges is to turn your design concept into a working prototype that demonstrates what the capabilities of a real network based on your design could be. This might mean a piece of hardware (for example, a single network node that runs your software), an MVP (minimum viable product) version of your solution or even a small-scale test network that users can connect to. Judges will be looking for a prototype that can demonstrate things like network speed, range and power consumption; please see the application guide for a detailed list of criteria <https://wirelesschallenge.mozilla.org/_assets/NSF.WINS.application.guide.pdf> . In July, a select number of Stage 2 finalists will be invited to a “demo day” showcase in Mountain View, CA on August 14th, where they will demo their working prototypes for judges. Finalists will be asked to give a short presentation that identifies the problem they are trying to solve, the intended users of their solution and the capabilities of their prototype. More details on the demo day event will be provided this summer. Congratulations on being selected to move on to Stage 2 of the Challenges! We look forward to reviewing your working prototype this summer. If you have any questions, please let me know. Thanks, Mehan Jayasuriya Program Manager, NSF-WINS Sent via Migadu.com, world's easiest email hosting

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
