		Re: RCX IR Transceiver Circuit
(...) Thanks for this one, Mark! For the sake of completeness, some data on devices used. Note: as there are "collisions" in SMD device names, these are only "very probable"... 1Kp: (URL) 3Kp: (URL) are NPN and PNP general purpose transistor. A4p: (...)

		IRPD sensors and LegOS (long)
Well, after much frustration and a great deal of help from the very wise Rossz, I was finally able to get up and running w/ DJGPP and LegOS 0.2.4 The first thing I did was write a program to use with Pete Sevcik's IRPD proximity detectors that he (...)

		Re: Decoding the LEGO IR remote control
This LEGO IR remote control (#9738) is making me crazy!!!! Dave and Kekoa have posted in depth explanations of the remote's coding, but I must be awfully dense and am missing something somewhere. I've tried two approaches: First, I used both a (...) (25 years ago, 19-Sep-99, to lugnet.robotics.rcx)

		Re: RCX Serial Hardware Hack
(...) The carrier should be quiet in any case, because it disturbs the TX signal. (...) We tried this,but it didn't work. Why, because the transistor will drain some current, if the emitter has positive voltage and the base goes low. If the carrier (...) (16 years ago, 24-May-08, to lugnet.robotics.rcx.legos)

		Re: IR questions
(...) Only transmitting keeps the tower alive, at least according to my tests. If absolutely necessary, an occasional 0xff sent by the PC will keep the tower alive; this will result in only a start bit being sent, which ought to occupy very little (...)

OK, the IRPD rover just smarter.

		GP2D12 Please help
Please help. I just recently got a Sharp GP2D12 ir distance ranger plus RCX interface device from mindsensors. It is pretty cool, however I am getting alot of flucuation in the readings and in turn I think that i am losing out on range. The maximum (...)

		RE: Custom Firmware, IR Problems, and Dead RCXs (long)
(...) Actually, there's a regulator on the Tower that takes the voltage for the digital side to +5 and keeps it there. The capacitor is only rated for 10V. The higher voltage will allow higher current through the IREDs as they are connected right to (...) (23 years ago, 26-May-01, to lugnet.robotics.rcx)

Retrace(int N) => Retraces the last N number of legs of it's journey. Change the #define LEGS (...) (24 years ago, 30-Aug-00, to lugnet.robotics.rcx.legos)

I've tried this already, and as you say, it works, but the sensitivity goes waay down. For a (...) (19 years ago, 13-Sep-05, to lugnet.robotics.rcx.nqc)

Agreed, LegOS is the way to go. Here is a LegOS program I wrote for a robot that keeps track of its heading in one of 8, increments (45 degrees intervals, numbered 0 to 7 heading clockwise). It keeps track of the last 10 segments in it's travels (...) (24 years ago, 21-Sep-00, to lugnet.robotics.rcx)

		Re: More RCX's controled by one tower ?
You cannot program them independantly, but you can make sure your programs respond to different IR messages during normal operation. All RCX's will receive the messages, but as long as only one responds with some action then independant control is (...) (23 years ago, 22-Jan-02, to lugnet.robotics.rcx, lugnet.robotics)
