(...) 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 (...) (21 years ago, 7-Nov-03, to lugnet.robotics.spybotics)

I feel a little sheepish posting such simple code, but I needed to write this function anyway, and it's a legitimate illustration of a couple functions, which is the goal of "Spybot Studies" and this is a run-on sentence. /* led_8bit_display A (...)

(...) 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 (...)

(...) My understanding (which may well be incorrect) is that the Manas unit only responds to IR. Sending an RC message using the PC channel is probably not terribly useful since (as far as I am aware) there aren't any devices that use RC messages (...)

I forgot to mention that the mana (set to channel 3) didn't respond to the laser LED's command message. Is this because the mana isn't sensitive to visible red or because the signal is somehow encoded differently when it comes out the laser? (or (...)

(...) Yes, there are multiple IR emitters. Two in front at nearly 90 degree angles, one in back, and a high-power one pointing up. Turns out my camera was only picking up the high-power emitter.
