Ever have one of those times where it's like "it ran outside the chassis!" then
you actually install the bastard and put everything together and it stops
working?
Last night was one of those times. Sacha had figured out how to make the two
bricks share sensor readings as I'm using four lights and four touches. (the
touches are tied together...) Works great on paper...and sitting on the table
with a third test RCX. Once in the r20 chassis?! Stops working.
I'm also not sure you can "watch" the RCX while the IR is running for send
messages...on two RCXes at once.
Either way, we're getting closer, but we're not there yet. All the functional
pieces are there, but the cabling's a pain. This thing has more wires than mob
informant.
