A friend of mine just bought a Lego NXT package, and its first project is a panohead!
He is using LabView, as it knows this software (it uses it at work), but I suggested him to write a NXT firmware which could be driven from Papywizard; this would just require a new plugin.
Is there anyone already developing on NXT?
For the mechanical part, anyone could build its own head, fitting its need...
Yes, I know, this is a silly project

Why silly ? It's a fun project

Here are a few interresting links...

Ok, someone on nxtasy.org told me that there is a python module to control the NXT! So, there is no need to develop a 'firmware': all can be done from Papywizard plugins

I am working on it. Head is handmade and uses LEGO NXT brick with one LEGO motor (@ this time). Resolution is 194000 / 360 deg.

Are you working on the Papywizard plugin? Or on the head?

it cross my mind. At this moment I am working on attaching second moving level. Let see after that.

Ok.

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.

Hi !
Lego NXT Brick + Papywizard ...... is this possible ?
Offline
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.

ok, tnx. Yesterday I made some test with Merlin+PW . Not bad ! My selfmade head uses LEGO brick. New mechanical version on my desk @that moment.

I have been experimenting with the NXT as well - http://www.flickr.com/photos/73571158@N … 635436569/

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!
