  Re: Spybot studies: SetTxDirection() confusion
 
(...) How *does* the Spybot know the orientation (the ROM SDK calls it "aspect") of another Spybot? My (casual) observations indicate that all three emitters are on simultaneously and synchronously. How does the observing Spybot identify which one (...) (22 years ago, 8-Nov-03, to lugnet.robotics.spybotics)

  Re: 9747 (RIS 1.5) comes with 2.0 RCX brick?!?
 
(...) Yes RCX 2.0 can communicate with spybot if you use "extra-soft" but not with RIS soft. RCX 2.0 does not work well with IR remote, you have to be exactly in front of the RCX 's IR port to pilot it. So you can' t pilot easily RCX2.0 vehicle with (...)

  Re: Spybot Studies: display an 8-bit value
 
(...) Another very simple thing to do to display this type of "debug" information is to send a message to an RCX, and display the value on the LCD of the RCX.

  Spybot Studies: display an 8-bit value

I think these emitters are different wavelength, 940nm for the pointing up one, 880nm for the others. 940nm radiation is very close to red wavelength range and is easily seen by cameras CCD, even though they generally include an IR filter to (...)
