Occidentalis Tweaks the Raspberry Pi OS for Electronics Hacking
The Raspberry Pi is already set up pretty nicely for doing pretty much whatever you want with it, but if you’re looking to run some of your own electronics, Occidentalis is a tweaked Linux distribution that packs in pretty much everything you need to get started. P
Occidentalis is built by Adafruit and based on Raspbian Wheezy. Included in this distro are a ton of kernel modules for servos, sensors, Wi-Fi cards, and just about anything else you’ll need to connect your Raspberry Pi to the real world. It’s also setup to automatically start sshd and Bonjour on startup, reminds you to change your password on login, and plenty more. You can grab the distro, the full list of features, and installation instructions over at Adafruit.
