|
I've been doing a lot with LNP lately, and I have a few questions. First, the lnpd package I have says in the readme that there is a bug in the legOS kernel with sending LNP packets from multiple tasks. Accordingly, all of my LNP-sending functions (...)

(...) 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 (...) (24 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 (...) (24 years ago, 12-Oct-00, to lugnet.robotics.rcx)

| | RE: Is Extreme Creatures Good? FOS stuff
|
|
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 (...) (24 years ago, 11-Oct-00, to lugnet.robotics.rcx)

When I did some work with the new control structures, I found out that they are quite nice (monitor and acquire). However, you could do the same in the past but you needed to split your program into several tasks which are controlled of a task (...) (24 years ago, 11-Oct-00, to lugnet.robotics.rcx.nqc)

(...) That's why my post ended on a positive note. It's not that I'm ungrateful. Without Lego I wouldn't have hundreds of thousands of bricks all over my house... heh heh. I also wouldn't have 3 RCX's, a Scout & a Micro Scout. Lego just moves very (...) (24 years ago, 11-Oct-00, to lugnet.robotics.rcx.nqc)

Also, several of the more annoying limitations of the original firmware were removed (or at least eased) (...) (24 years ago, 10-Oct-00, to lugnet.robotics.rcx.nqc)

(...) 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 (...) (24 years ago, 10-Oct-00, to lugnet.market.shopping, lugnet.robotics.rcx, lugnet.robotics, lugnet.technic)

All we can do is hope that the few people they do ask for feedback will point out these 'lacking' points. But, since version 2.0 (...) (24 years ago, 10-Oct-00, to lugnet.robotics.rcx.nqc)

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 (...)

At last! I decided to test the cygwin installation on NT and it worked! I still have to use the -s option with firmdl3 but the rest is perfect. Now I have the djgpp distribution on Windows9x and the cygwin distribution on NT. (24 years ago, 10-Oct-00, to lugnet.robotics.rcx.legos)

(...) 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 (...) (24 years ago, 10-Oct-00, to lugnet.robotics.rcx, lugnet.robotics, lugnet.technic, lugnet.market.shopping)

Sorry, Dean - now I got your point. There is indeed no way to read the contents of the datalog. What about storing the data (e.g. for path information, maps, etc.) into an ARRAY instead of the datalog? With RIS2.0 and the latest NQC version you have (...)

(...) 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 (...)
