continuos rotation?

hello everyone im making a robot, and ive accidently bought my self non-continous servos. so i was on my way to convert them yo continous rotation and reading all the how-to's it says you need to use a servo controller to set the servo to the center position before beginning, but i do not have a servo controller. please tell me if i can just do this without setting it im just making a  small r/c or autonomous robot. if i need to can i just go ahead and skip that step do everything else and then wait for my arduino and motor shield to come in and then set it to center position?

Add-ons to the "bristlebot"

Have any of you added something cool to your bristlebots to make them do something cool (like obstacle avoidance, remote control, etc.)?

can't change direction or speed of modified servo

I've followed the steps on this site to modify my servos for continuous rotation:
