This is an interesting thread, in as much as I have a couple
of RCX R/C evaluation units currently being tested.
Having already built a UHF extender to sit between the PC
and the RCX IR communications interface, I can say that it
is of doubtful value, only because it cost about as much as
an RCX (~$125) to build. Given the choice I would go for
the second RCX!
But once you start building with multiple RCXs, the value of
the Lego IR remote rapidly diminishes, because it commands
all RCXs at once.
That is why I came up with a "receiver brick". The brick is
active sensor compatible and converts button pushes from a
remote transmitter very similar to a keyless entry device into
different sensor readings. The readings can be decoded by the
RCX software to perform any desired functions.
I actually intended it to be used for "supervisory" functions
but I can see it being used to build remote controlled RCX
based "things" too.
The details will go up on the HiTechnic stuff website in a week
or two.
