What kind of battery packs were you using for them? What's their<br>
discharge profile look like?<br>

Not sure what the discharge profile is, I just grabbed the largest
capacity USB battery packs I found. It's basically one of those
"Charge your iPhone on the go!" type of battery packs. I'm currently
working on using D cells to power the RPi, but the cheap step-up
converter I'm using doesn't provide a clean enough 5V...<br>

A few things about building on top of Raspbian:<br>
<br>
Raspbian/Wheezy is remarkably stable at this point in time. Keep
in<br>
mind that even if you have the experimental repository turned on,<br>
everything available will still be a couple of releases behind.
If<br>
something goes wonky, you might want to look into a custom compile
of<br>
the package with a newer checkout.<br>
<br>
Make Debian packages for your code and build a repository for
them.<br>
You won't be sorry.<br>
<br>
AIDE and Blueprint are good for keeping track of the Debian-level<br>
config files that you'll have to modify to make everything work<br>
smoothly. You'll have to reconfigure more than it seems at first
scratch.<br>
<br>
For what it's worth, we used the packaged version of olsrd in the<br>
Wheezy repository (0.6.2-2.1) with the version we built for
Byzantium<br>
v0.3a (v0.6.4) and encountered no compatibility problems. Your<br>
olsrd.conf file Just Worked(tm) with it. :)<br>
<br>
To free up compute cycles, turn off the X desktop. You won't be
sorry.<br>

We have plans to package Commotion components for Debian and a PPA
for Ubuntu. I currently have a custom Raspbian image for my
MediaGrid project, which I made by mounting and chrooting into a
Raspbian image, and then installing/removing components and adding
configurations and boot scripts. But yes, Debian packages would be
ideal. There's plenty of things like X and Pulse audio that can be
removed.<br>

These are what we got to work when we ported Byzantium to the
RasPi:<br>

Useful list. Did they all work okay? Even the high powered ones?<br>

If the power consumption of a wireless interface gives you
problems,<br>
plug it into a powered USB hub. We have a couple of setups in
which<br>
the RasPi and wireless device are plugged into (and thus powered
by)<br>
such a thing, and it makes for a neat development package.<br>
