After an email exchange with Gerrit Bronsveld from the Netherlands, and due to
the fact that he doesnt have a Lugnet account, he passed on the info to share,
and has told me that he has taken many photos and will be posting them to
Brickshelf (under the name - geobot) in the next few days... Keep your eyes
open.
For now... this is what he shared with me......
----start----
Here are some facts....
13 RCX units that communicatie all togethers (in 2 communication chambers)each
has a seperate program.
Games played: so far more than 400 children played a game at LegoWorld
2005(without any real malfunction)
High score so far: 3640
Build Time: +300 hours
Number of parts: +20,000 bricks
Weight: 30 Kg
Design & Idea by: Gerrit Bronsveld
Build by: Gerrit Bronsveld and Martijn Boogaarts
Program: NQC (by Gerrit Bronsveld, +100 pages A4), multi state, multi
tasking, asynchonous communication techniques
Lego: 99,99% (except for ball, some alu-paper in the communcation
chambers
and the paper for the display rolls)
Smarties
a.. Removable RCX-computers for fast battery replacement
b.. Asynchrone points display Display (display is much slower then points are
collected, but its always correct)
c.. 2 IR (infra rood) communication chambers
d.. Chamber A: 1 RCX (GC Game Controller) talks with 6 other RCX
units
(Display, Flippers, New Ball, PINBALL)
e.. Chamber B: 1 RCX (PC Point Collector) talks with 5 other RCX
units(Gates, Bumpers and Targets)
f.. Communicatie between the 2 chambers via Rotation Sensors
g.. Tilt Switch (simple but effective)
h.. Flipper protection, abuse of the flippers is punished by
temperarally
blocking the flippers
i.. Real working Coin-In mechanismn. Wrong coins are rejected.
Features
a.. Grand-Slam upper level (lits P I N B A LL)
b.. Top Gate (3 lanes) (1 point each, 10 points for all 3)
c.. Touch sensitive rotation bumbers (1 point each, 10 points for all 3)
d.. Bottom Gates (3 lanes) (1 point each, 10 points for all 3)
e.. 3 Drop Down Targets (10 points each, 50 for all 3)
f.. 3 Hit targets (10 points each, 50 for all three)
g.. Kicker Door (gives 10 points)
h.. 1 Exit Gate with Switch (when special is lit, extra ball+100 points)
i.. Kick Back function (10 Points)
a.. Demo mode (everything starts blinking)
b.. SPECIAL Mode (red Lamp, gives 100 points)
c.. Extra Ball function
d.. Points Display 0 to 99999 (is always correct)
e.. Tilt Switch
f.. Collection P I N B A LL letters (gives special)
g.. Black Hole (opens and closes automatic for Special Mode and Extra Ball)
h.. High-Score function
i.. Coin Insert function

I had the chance to see it in person at LW2005, with a demonstration of all its
features by Gerrit. That's a true masterpiece, with all the bells and whistles
of a real pinball game. A glimpse on it:

Hi ALL,
During LEGOWORLD 2005, we (Gerrit Bronsveld and Martijn Boogaarts) have shown a
-real-live-size- Pinball machine.
Unfortunately, were not all of you able to visit the Netherlands in order to see
the machine, and play it.
On http://www.pinballnews.com/news/lego.html an article is posted with all the
interesting features of the machine.
Some minor LEGO facts that I can add to the article:
- Even the tilt of the table was done by using LEGO DUPLO bricks.
- The coin detection mechanism is tilted in 2 opposite directions compared to
the machine itself to make sure we detect the right coins.
- There was actually one input port short so we could not detect when to close
the gate in the shooting lane, even though we had a gate with motor inside this
lane.
- If you look close in the communication chamber we used the part
http://www.peeron.com/inv/parts/30208 30208 Cylinder 4 x 4 Hemisphere
Multifaceted to reflect the IR light to all the RCX units.
- All the 13 RCX units have their own program.
As a builder I must say that this machine once more has proven that the power of
LEGO and LEGO MINDSTORMS, is in your mind, if you can think about it you can
create it. We have (once more) gone to the technical limitation and beyond.
Stay tuned for our next stunning project !

And it is really impressive! Wonderful job, and a very nice write-up. A few
questions:

> Multifaceted to reflect the IR light to all the RCX units.
Neat solution. I was wondering how you networked between the two IR
communication chambers (the article is a little vague, refering to a "direct
feedback loop" which could be anything). Also, as the point collector
communicated with five other RCXs, how did you keep from loosing message in this
chamber?
Also, the article mentioned that "So it was a real challenge to come up with
a system to guarantee that the display and the 'internal' points are equal." How
did you end up doing that?
Again, your creation is a very wonderful application - I'm sure it was
wonderful seeing the faces of all (kids & adults) as they saw this.

not sure what you mean:
but - we have 2 chambers, therfore 2 main listners, this made sure the point
collector (PC) was able to recieve all the points, and this RCX uses a
motor-rotation sensor-rotation sensor construction to transmit the points to the
newball RCX. thisone also has a Motor-rotoation-rotation construction to
feedback the counted points.
the newball RCX uses IR to send the points to the 2 RCX's used for the main
display.

mechanical (see above)

sure it was ! we enjoyed showing it to them.
(I plan to create a little movie so you can see it as well :)

You answered my question very clearly, thank you. This sounds like a nice
feedback system using the rotation sensors, and could be used to signal a lot of
things. Do you use a single axle connecting two rotation sensors where the axle
can be turned by either RCX (this would require two motors and two rotation
sensors), or does each RCX have a dedicated output system and a seperate
dedicated input system (this would seem to require two motors and four rotation
sensors).
I assume the RCX collecting the points would not have trouble with
simultaneous IR messages because only one "scoring event" would happen at any
one time (the ball could only hit at most one target or scoring device at a
time). Did the point collecting RCX need to identify where (which RCX) the
points were coming from?

Fantastic - I look forward to seeing it!

have a look at the following deep link;
http://www.brickshelf.com/cgi-bin/gallery.cgi?i=1490167
We used 2 motors 2 axles and 4 rotation sensors:
one set for signals towards the newball RCX and one back towards the Points
Collector RCX.

Right only one IR message at a time.
there is no indication where the points came from, since this is not nessary
information.

I did not have the time yet to make a nice movie please have some more pacient.
in the mean time look at this:
http://www.brickshelf.com/cgi-bin/gallery.cgi?i=1490235
and the main, pinball link (maybe not yet working)
