Step 2: RaspberryPi Configuration

So you have a RaspberryPi.  I'm not going to cover software installation and basic setup, because there are already some great tutorials out there.  Here are some helpful links for that step:

I recommend Raspbian, simply because I'm a Debian fan, and Raspbian is Debian, but optimized for the Pi.  If you already have a preferred distribution, great.  Use that. 

One thing that I do not like about the Pi is the lack of a heatsink over the CPU.  I don't care what anyone says about passive cooling, something about a CPU without a heatsink on it really, REALLY bugs me.  So go ahead and slap a tiny heatsink on your Pi's CPU.  I used a RAM heatsink from a pack of a bunch of them that I got at Microcenter.  This is ironic, since the Pi's RAM is on top of the CPU.  Anyway.... some folks are putting heatsinks on other chips, which isn't a bad idea.  I just happen to be bothered by the exposed CPU.  Plus, the heatsink does get hot during operation.  So it's definitely doing something. 

I then connected the WiFi dongle and my keyboard's wireless dongle to the Pi, and put it in the cell phone case.  I rested the Pi on a part of an anti-static bag, just to avoid shorting anything out. 

NEW 11 March 2013: I'm now using a 3D printed case for it.  The cell phone case offers the same features, but this printed case is a part of my transition to a slimmer and even more portable version I'm cooking up for the future.  This case is simply thing 33694 from Thingiverse. with a belt clip, thing 39983, hot-glued to the bottom. 

I have also swapped out the blue aluminum heatsink for a copper one, but that's not necessarily any better than the aluminum one since the Pi only produces negligible heat.
