You can also use the pins of a RaspberryPi as a PWN output and do the same thing with only 3 inexpensive power transistors: http://mitchtech.net/raspberry-pi-pwm-rgb-led-strip/

Instead of servoblaster I recommend you to use PiBlaster: https://github.com/sarfata/pi-blaster

Awesome, thanks for the heads up! Like it says in the blog post, PWM + transistors was an option I was thinking of (and still am if I ever decided to dip into dedicated hardware later on), I just wasn't sure if I had the electronics chops yet to not blow something up.
