In case anyone was wondering (yeah, sure :-), this line in my original post: lediDisplay = (x & 0x17) ((x & 8) * 4) ((x & 32) / 4) rearranges the bits so that the lower 6 bits can easily be read left to right (while looking at the bot from the (...)

| (...) 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. That way, you don't need to mess with decoding the 8 bit binary number. This was not my (...) (22 years ago, 7-Nov-03, to lugnet.robotics.spybotics)

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 (...)
