The pan-tilt rig

As I mentioned before, the pan-tilt rig takes relatively little time to construct

You can see from the picture the rig is built using wooden blocks I cut out of scraps of 2x4. The servos are connected to an Arduino via a servo shield I constructed last year for a robotic platypus. The battery in the background supplies power to the servos and while it probably is not necessary when only two servos are involved (a single USB port should supply enough current), the way the shield was constructed necessitates and external power source.

I will eventually construct a nice little enclosure for the rig, the Arduino, and the camera, but I'm more excited about getting something that actually points up and running.

The next step is to write code for the Arduino that allows a computer to actually control the servos.

Finally, as a note to those that know me, I plan to make this rig fully compatible with a wiimote for a more futuristic pointing experience.
