It's (been) alive!!!
11/07/14 3Jesse Alexander, WB2IFS/3
It all started with a troll I put on linkedin.com..

Then I got...

Basic Idea: when all else fails “send in the Cloud”
● Mesh Web server connected in a true cloud: mesh of diverse devices providing diverse services
● Survivable
– Self healing
– Low power consumption (battery/solar operated)
● Deployable
– Mobile
– Portable
– Battery backed solar
– Small and lightweight

Uses
● Emergency management site
● Winlink.org/Mesh Gateway
● Digital Resource net: Knowledge for deployed volunteers (manuals, ICS forms, private email and chat, etc.)
● 3rd responder Situational Awareness
● VoIP and messaging server (D-RATS, Echolink, etc.)
● Health and welfare site ( Red Cross safe and well, Ushahidi mapping)

Use Case: over Hamnet
11/07/14 12Jesse Alexander, WB2IFS/3
Use case: Overlay Network Tiers

Raspberry Pi Installation
1.Install basic firmware and remote login support
2.Move main partitions from Flash Card to HDD
3.Install Hardware and software for GPS/RTC support
4.Install web server and Content Management System
5.Configure HSMM nodes
6.Create content for web site
http://www.raspberrypi.org/
11/07/14 16Jesse Alexander, WB2IFS/3
Install basic firmware software and remote login support
● Connected the PI to TV analog input and used USB keyboard and mouse
– http://www.raspberrypi.org/faqs Has instructions.● Installed & configured PuTTy client on test laptops (except for
the MacBook which doesn't need it)
● Configured static IP on the PI
– http://www.penguintutor.com/blog/viewblog.php?blog=6306● Installed tightvncserver (Optional)
11/07/14 17Jesse Alexander, WB2IFS/3
Move main partitions from Flash Card to HDD
● I tried other instructions but these worked best for me: http://www.raspberrypi.org/phpBB3/viewtopic.php?p=275750#p275750

Pi doesn't have a real time clock!
– Adafruit GPS provides battery backed RTC function
– Network Time Server capabilities
– Location telemetry!
– See https://www.adafruit.com/blog/2012/08/28/adafruit-ultimate-gps-on-a-raspberry-pi/
https://www.adafruit.com/products/746
11/07/14 19Jesse Alexander, WB2IFS/3
Install Hardware and software for GPS/RTC support
● Configured Pi to allow use of /dev/ttyAMA0
● Installed minicom to test Adafruit Ultimate GPS
● Installed ntp
● Installed gpsd
– Configured it to use /dev/ttyAMA0
– Configured gpsd.php in /var/www
● See the following sites:
– http://www.akadia.com/services/ntp_synchronize.html
– http://www.catb.org/gpsd/index.html

11/07/14 21Jesse Alexander, WB2IFS/3
Install web server and Content Management System
● I used instructions from this site: http://mitchtech.net/wordpress-on-raspberry-pi/
● I also configured WordPress.org with a “child Theme” so I could hack it without losing configuration during upgrades
● Configured gpsd.php to display localized information with gps status
● Used the WebMail/Paclink install instructions from Active Ham to set up the webmail system
11/07/14 22Jesse Alexander, WB2IFS/3
Configure HSMM-MESH node● Took several tries to find the right configuration for
the HSMM-MESH node connected to the PI
● Wordpress.org is persnickety about IP addresses—especially when it comes to pictures
● The 5-host DMZ mode worked best
● Needed the “search and replace” WP plug-in to clean out unroutable addresses from first pass Wordpress.org configuration on the PI
– Noticed that the pictures didn't load because of bad references
– Replaced IP address with “wb2ifs-103-rpi/wordpress” URL

List of Wordpress.org Plugins
Plugin Why it's installed
List Yo' Files Package support for e-gokit
Quick Chat Allow operators at multiple stations to collaborate in real time
Search & Replace Allows the changing of the servers IP address in all the wordpress tables
Vasaio QR Code Allows easy data transfer from Wordpress pages to smart phones and tablets
PHP Code widget For the “on line” detection widget
Updraft + Backup and restore

Next steps● Add system status page for vitals telemetry (CPU temp, usage, memory and disk
capacity, etc.) DONE
● Add Paclink integration for Webmail via ham radio DONE: RPi is web server and Paclink running on Laptop with Kantronics modem and VHF Radio (Rpi may not have enough “horse power” to run it all)
● Set power budget for solar array and battery capacity (Calculated need for 100W PV array, very expensive)
● Determine best way to package system
– Using outdoor box
– Considering using Rootenna enclosure
– Using an old plastic tool box
– Inverted 5-gal jug “bell-jar” vs. briefcase vs. NEMA box
– Pi components are rated for commercial temperature range 0-70deg C will it work outside?
11/07/14 30Jesse Alexander, WB2IFS/3
Next steps● R&D on integration with Commotion Wireless and Project Byzantium
● Replace AP with 2nd Raspberry PI running Broadband-hamnet
● Considering replacements for Raspberry PI because I'm maxing out RAM and the Hard drive latency is increased because of its connection to the USB port:
