If you missed the Great Ball Contraption (GBC) at BrickFest (BF), you can get caught
up here:

Brian Davis and I spend a great deal of time working out the details for the train,
which became the backbone of the GBC.
After much discussion, the GBC was designed to be split into four sections, with the
train shuttling balls between sections. This design allowed us to shut down any of
the sections, and have the train bypass them, when they needed repair.
The train track was a single oval located behind the modules, and split into two
sections, as seen here:

Each half consisted of an RCX that controlled an area of track, four stations, and a
"transfer segment". Two trains ran at all times (if possible).
One device that allowed us to run four stations, only using one input and one output
from an RCX was the "Polarity Switch Assmebly" (PSA). The PSA included a touch
sensor, and a polarity switch. However, with all of the stations, it was possible
to trigger the touch sensor, without engaging the polarity switch, which caused
problems.
If you've read this far, you should be caught up. Now, we just need to figure out
what to do with the PSAs...

| With First Lego League starting in September, the main focus of LafLRC will be on that. However, with most of us being unable to participate, there will still be some side projects/events going on. -- Here's some upcoming events: October 15&16 - (...)
