ho hum. another day, another Great Ball Contraption.
In our latest gathering, Tom invited us to his house. Turns out, we have more
ball contraptions than Tom has table space in his basement.
So, we moved the tables, and set-up on the floor. Of course the next problem
was that I couldn't fit the whole contraption in one picture.
So, here's two:

I have some video, but it appears brickshelf is blocking all video.
It's very interesting to note that all the modules conform to the spec. One of
the modules used to turn the stream has a movable input bin. The other has an
input bin set far enough out that a module can be placed behind it.
The "hot new module" for this gathering was John's Spybot controlled paddle
wheel. The wheel was driven from the Spybot, through a differential. If the
wheel got stuck, the differential would turn, releasing the touch sensor on the
Spybot. The Spybot would run the motor backward for 1 second, then continue
forward.

Hey Steve, how can I get in on one of these gatherings.. I have a mildly
spectacular module I'm working on right now.. I'd love to bring it once I get it
working right...

Joe (and anyone else interested)
This is currently a project of the Lafayette LEGO Robotics Club in Lafayette,
Indiana. You're welcome to attend our meetings, which are held the 1st & 3rd Sunday
of the month, from 2-4 at the West Lafayette library (that's this Sunday).
You're very welcome to join us, even if you don't have anything to show (or anything
working). E-mail me for directions.
Steve

I just mailed out a bunch of balls to people that requested them.
If I didn't send you an e-mail stating that I sent you balls, then I lost your
request. Sorry. Please ask again.

Cool. I'd love to start a GBC activity here in Potsdam, but .... we
need a reliable source of bulk balls. It's nice of you to mail them
out to people, but we really need Lego to sell bulk balls. How do we
convince them to do it? Maybe we should create a fake Lego product,
the 2970 (to pick a number from the air), the Bulk Soccer Ball kit.
Then everybody calls S@H the same day and tries to order it.

Before Steve gave me some balls (oh, the straight lines...), I acquired
enough to run a few modules of my own from various Bricklink purchases. You
could do a GBC by simply mandating that everybody who wants to add to a GBC
brings there own supply of balls, but I think this project could tap out
Bricklink. But I agree, it would be nice if at least a few other folks could
acquire a large lot of soccer balls in other geographic regions.
> we really need Lego to sell bulk balls.
There is, I've heard tell, some PaB (not in the States, but UK IMS) that had
soccer balls for bulk sale. I know you can get a lot of soccer balls in a PaB
cup (a small cup here in the States holds about 180 - I don't have enough (yet!)
to tell how many a large PaB cup holds, but it looks to be around 300).

Well, I do have a very large suppily, and despite sending out hundreds of soccer
balls, I've just scratched the surface.
I have a whole stack of requests, just waiting to be boxed and shipped. I just need
to get to the post office during work hours... (sorry)
