Hey DJ,
I was just wondering what you are using on the ez-b to get 3.3v
i saw this tutorial but i'm not sure if it will work.
Ultrasonic Collision Detection
— Stops robot movement (no steering) when an EZB-connected ultrasonic sensor detects an object within a set range; integrates with scripting and paused polling.

That link doesn't respond. There are 5v and 3.3v on the ez-b.
there are 2 5 volt supplies. one is for the i/o, the other is for the micro and bluetooth module. they are seperate so the chip doesn't brown out from the i/o
the 3.3 is created by that little VR on the side by the little power plane. i forget what 3.3 VR is being used hahaha
could it be this one:
click?
