Okay, here’s a low-res video of the GBC. It doesn’t show my module for very
long; the camera was still setting itself up to record and I thought I had stood
there long enough, but I hadn’t. Anyway, it runs for 9:39, has a couple spots
where I had to stop and restart filming due to module problems, and as mentioned
before has no Gus action. Other than that I think it’s pretty good.

I’d be glad to share my code with you if you like, but the secret is
really in the polarity switch assembly located at each station (a Hassenplug
brainstorm, BTW). When the 2x2 cylinders under the train baseplates bumped
the sensor wheel, it did two things: released a touch sensor (connected in
series with all the other station touch sensors) to signal the RCX, and threw
a polarity switch to connect that station’s mechanism to the RCX. When the
RCX provided power to the “station mechanism line”, only the station with the
polarity switch thrown actually got power. Net result was that any number of
stations could be run using just one output & one input. Steve & I wrote
our code completely independantly, and I have to admit I’m not happy with it
yet. Positioning the hoppers to within +/- 0.5 studs with an accuracy of more
than 98% is... tough. Mine is in NQC, while Steve’s is in BrickOS (I think).

You know what? I think I’d rather just have pictures of the train cars, the
touch sensors, and the loader/unloader mechanisms (I should have done this
myself but I forgot to when I was there). I’ll write my own program. If you have
pictures posted, please show me where. Thanks!

| (...) Nothing to apologize about - Gus was out there "on his own" because we wanted to make sure everybody *elses* modules got in. Gus has been videoed before. The only thing I wanted a video of with respect to that was the amazed looks on so many (...) (19 years ago, 17-Aug-05, to lugnet.events.brickfest, FTX)
