That I can believe - he's amazingly good at that. I just hope my modules didn't
give him any trouble.

It works very well that way for closing loops - both Steve and I can switch the
trains from "circulating" to "ping-pong" mode at will, although usually in a
given show on one mode is used.

*That* I'm really sorry I missed. Gus, Dave, and the rest of the SMART group
were my inspiration for my forklift GBC module... so much that after a lot of
correspondance with him, I ended up naming my (RCX-based) forklift "Gus". With
all the recent stuff, I've not had the time to pull it out and improve it much,
but the NXT forklift sounds wonderful. Any video out there on this yet?

Do you have pictures up (Brickshelf, other)? Or at least an explaination?

Did things keep binding up because of tight clearance?

I look forward to it - it's a talk I'd have loved to sit in on. And yeah, a lot
of it could be summed up in two points:
1) Follow the Spec... the Spec is good... always follow (or exceed!) the Spec.
and
2) Test the module until your eyes bleed, and then do it again.

As mentioned, that was John Brost. He worked hard on that module, after many of
us just said "yeah, I'm sure that would work". He's the guy that actually went
out and put it into practice. That's another thing I really hope to see in the
future.

Well, I wish I could have been there, and missing the festivities a lot as
well... but on the other hand I did get to do a 9 mile hike up above the
treeline (in 4 hours... altitude can really make things interesting) in
Colorado, so my day was fairly full as well :-).
