Just dropping a line... Posting via a small broadband-hamnet mesh, running HSMM-Pi.
This is working quite nicely. Only two nodes thus far, but working on more, now that I've spec'd out hardware and the install procedure.

Cool! I've been interested in playing with that.
All the world’s a stage, but obviously the play is unrehearsed and everybody is ad-libbing his lines. Maybe that’s why it’s hard to tell if we’re living in a tragedy or a farce.
If you have a Pi that you're interested in installing it on, I'm going to post a base image with all the work done, and an install script that puts all the pieces together for one of the ralink USB dongles. I'll put a link up here when I get them together.Originally Posted by KJ6BSO
Well........that might just be the impetus required to make you quit playing with yourself, eh?
Actually, with the price of a PI these days, that could be a lot of fun to experiment with.

Duplicating the efforts via scripting is turning out to be a large pain in the ass. I had this working (When I posted this), but now trying to script this out, it's turning royally painful.
Namely, it took me two days to get two working nodes. So, I decided to re-do one of the nodes, so I can contribute the work back (As an install image, or scripts). Turns out I'd need three scripts: The ralink driver builds require 3 reboots, I've learned, or rather re-learned.
The hsmm-pi portion isn't difficult (A git pull, and install), but the driver needs to be rebuilt. And, for unit testing, I need to go to a clean slate, to test. The kernel source clone takes forevveeeeeeeer to do. The whole driver build process is about 2 hours long (Oh, how I wish I knew how to do cross-compiles).
Ok, boils and ghouls... I'm grabbing an updated, clean HSMM Pi image as we speak. I forgot to change the SSID back to what it's default, so you'll want to change that (It's currently "KAISERTOWN", default is "HSSM-MESH"). Passwords are are defaults (Web interface is "admin" and "changeme", SSH is "pi" and "raspberry").
It's configured as a Inet gateway, with an Node address of 10.0.0.1/8 (This allows you do bump all of the octets shy of the first for your mesh, giving you a HUUUGE number of networks). It's eth interface with get a DHCP address from your router once you plugin.
I'll be posting the link for the image shortly.

So, while the image is uploading, here's a quick how to, and shopping list for a single HSMM Pi node.
(Image should finish uploading in about 90 minutes, and will be located here: http://bit.ly/1kZa6id)
Shopping List (Amazon Links included):
* Raspberry Pi Kit - Pi board, case, and power supply (http://www.amazon.com/CanaKit-Raspbe...ower+Supply%29)
* MediaTek 7160 (http://www.amazon.com/150Mbps-Wirele...s=qibox+ralink)
* 8GB SD Card (http://www.amazon.com/PNY-Optima-Cla...ds=8GB+SD+Card)
Shortcut:
Use Win32DiskImager (https://wiki.ubuntu.com/Win32DiskImager) to burn the above image to your SD card. It'll work out of the box: Connect it to your router, connect to it with a web browser, configure, and reboot.
The below has shamelessly cribbed from the following:
http://va3paw.com/2014/03/16/hsmm-mesh-on-raspberry-pi/
https://github.com/urlgrey/hsmm-pi
Long steps:
- For ralink USB cards (mediatek 7601):
* Execute the following:
Code:sudo bash apt-get update apt-get upgrade rebootCode:rpi-update reboot* This part is needed for any wireless card, even if it already works for the Pi out of the box. This installs the HSMM Pi software.Code:cd /usr/src git clone https://github.com/raspberrypi/linux.git sudo ln -s /usr/src/linux /lib/modules/`uname -r`/build cd linux make mrproper zcat /proc/config.gz > .config cp .config .config.org sed -i 's/^CONFIG_CROSS_COMPILE.*/CONFIG_CROSS_COMPILE=""/' .config make modules_prepare wget https://raw.github.com/raspberrypi/firmware/master/extra/Module.symvers cd /usr/src wget "http://www.mediatek.com/AmazonS3/Downloads/linux/DPO_MT7601U_LinuxSTA_3.0.0.4_20130913.tar.bz2" tar -xvjpf DPO_MT7601U_LinuxSTA_3.0.0.4_20130913.tar.bz2 cd /usr/src/DPO* sed -i "s/ULONG RTDebugLevel = RT_DEBUG_TRACE\;/ULONG RTDebugLevel = 0\;/" os/linux/rt_linux.c make make install exit
Now, go and configure your node by connecting to it via port 80. IMPORTANT!!! Do not reboot the pi until you've configured the node. Otherwise, it will not bring up any of it's interfaces, and you'll need console mode to bring up an IP.Code:cd ~ git clone https://github.com/urlgrey/hsmm-pi.git cd hsmm-pi git checkout tags/v0.4.0 sh install.sh
If this node will be connected to your router, in order to supply internet access to the mesh, leave it as a WAN device. If you will have clients connected (Via it's eth interface) configure it as a "LAN" node. The pi has a neat feature where the ethernet connection doesn't require a crossover cable, it will autonegotiate the connection even with a straight cable. So, connect it to your laptop :)

This sounds awesome. I would love to experiment with setting this up at the ham shack on campus and using it to get free internet.Give us the details on the network capabilities; range, speed, etc...
Range and speeds are all dependent on Line-of-sight, antenna, and distance. Clear LOS, you can get 5 miles easily at 11mb/s using directional antennas.This sounds awesome. I would love to experiment with setting this up at the ham shack on campus and using it to get free internet.
For the USB dongle I have been testing in the links, I get about 70 feet, with clear LOS, and about 30 ft with obstructions (Such as homes). Of course, that's all Part 15. Under Part 97, I could use up to 1500W (Don't suggest more than 1 or 2W, however).
They don't make xfering a 1.9GB file easy these days... Trying again.
