Interesting thread.... I actually am begining a project where I will build a 6 foot dolly and control the dolly using my Lego NXT 2.0 kit, one motor with gearing and a toothed belt and controlled by the NXT Brick with programing with Lego Mindstorms 2.0 program.
I already have the NXT kit assembled and am working on getting the Track and Carriage put together. I am also trying to work the problem of building a remote shutter release that I could plug into the NXT.
If I could build this and mount my Skywatcher Head on it and control both using Papywizard for full 3 axes control of my camera for Time Lapse this would be awesome. Too bad the papywizard/Merlin head combo doesn't include 3 full axes of control for a third motor.
The Lego kit is actually more serious then you would think.
Mike Lanfor Celestron Skywatcher Panohead (firmeware version=010981), Papywizard, Nokia 800 (OS2008), Win 7 64 on Sony VIAO, Canon 7D, 40D, 30D with Canon 70-200mm F2.8L IS, 24-135mm F3.5 IS, Sigma 15mm F2.8, Vivitar 7mm f3.5 Fisheye for Canon (manual lens), Sigma 135-500mm f3.5/5.6. Focus Time Lapse and Spherical Pano's/pano tours (Autopano gig and Tour). Dynamic Perception Dolly with MX2.
Sure it is! But I don't own a NXT, so I can't make tests. What you need, is a way to drive it from python. There is a python module to do that, which means that you don't need to write a firmware. But I don't know what is possible and what is not.
The other way is to write some low-level functions in a NXT firmware, so it will answer more or less like a Merlin.
Canon 20D + 17-40/f4 L USM + 70-200/f4 L USM + 50/f1.4 USM Merlin/Orion panohead + Papywizard on Nokia N800 and HP TC-1100
I have built several heads using the NXT and they all worked, but I think this one is the most convenient to use.
Certainly the last one I will be building!

A sophistical rhetorician, inebriated with the exuberance of his own verbosity, and gifted with an egotistical imagination that can at all times command an interminable and inconsistent series of arguments to malign an opponent and to glorify himself.
