Some of them used 30+ motors and they basicly ripped each other to pieces. There was also a section (...) (26 years ago, 12-Oct-00, to lugnet.robotics.rcx)

Time to jump in.... The FOS uses a small surface mount LED. It's about 2.5mm x 3 mm and mounted to a thin PCB. There are what look like diodes and what I would guess are current limiting resistors on the board also, so good luck trying to have (...)

(...) Yes. Of course. Those are the best ones. LED's are basically just Diodes that make light. So you can "Twist" two LED's together to get one on each polarity. Like I was saying above, my favorites are the tri-coloured LEDs... Dean -- Coin-Op's (...) (26 years ago, 10-Oct-00, to lugnet.market.shopping, lugnet.robotics.rcx, lugnet.robotics, lugnet.technic)

In theory it's possible, provided that: [1] The optical frequency matches adequately (anyone know?) [2] 38400 Hz is close enough to the RCX/Scout modulation frequency to get past any bandpass filtering.. [3] The PC software can accurately turn IR (...)
