(...) I once saw an incredible site about a challenge set by Lego for people to make robots that destroyed each other, but only using lego elements. 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)

Hi all, Anybody has tried the topic in subject? Any interesting references? We've got just one so far: (URL) Pavel Petrovic, petrovic@idi.ntnu.no PhD student, Department of Computer and Information Science, Norwegian University of Science and (...) (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 (...)

I think what you're looking for is the MIT handy board. Take a look at (URL) is a 68HC11 Micro controller with expansion boards, servo outputs, digital outputs, lot's of neat stuff. An assembled and tested handy board is about $299. There is a (...) (26 years ago, 11-Oct-00, to lugnet.robotics.rcx)

(...) 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 (...)

Hi, this is not exactly RCX-related, but I thought that some of you might be interested. It's a robot conrolled by a Palm. You can find it here: (URL) Bye: Andi S. PS: Please mail me if this posting didn't belong here (26 years ago, 10-Oct-00, to lugnet.robotics.rcx)

(...) Yes. Radio Schlock has a few: orange, definitely (but I think it's one of the 10mm "jumbos", so it wouldn't fit). And I'm pretty sure they have green in smaller sizes. BG Micro (www.bgmicro.com) has some real stunners, that have just hit the (...) (26 years ago, 10-Oct-00, to lugnet.robotics.rcx, lugnet.robotics, lugnet.technic, lugnet.market.shopping)

(...) Ahh, to bad. I wonder if there are any other colors in "ultra bright"? (...) you'd (...) Actually I think there are LED's with only two legs with the "two-color" feature. I'll have to investigate this and come back to you. /Joakim (26 years ago, 10-Oct-00, to lugnet.market.shopping, lugnet.robotics.rcx, lugnet.robotics, lugnet.technic)

(...) If you don't use a tiny ultra bright one you won't get much... Also, the circuit it the thing is already making sure the power flows to the LED one way. So you'd have to disable that as well if you want the multicolour LED's. My favs are the (...)
