Hello, I decided to scrape my machine today and when I tried to reinstall legos I ran into a problem compling the cross compiler under cygwin. Here is a list of the packages I have installed: Cygwin Package Information Package Version ash 20020131-1 (...) (23 years ago, 14-May-02, to lugnet.robotics.rcx.legos)

Someone has a site with a video of a robot they made. In the video, you can see the two IR LED's blink. The site owner made a comment about what the blinking was caused from. Unfortunately, I don't remember the site address... I think the site had (...) (23 years ago, 14-May-02, to lugnet.robotics)

(...) IR sensors (of the type used by the military for night operations for example) operate over some fixed range of IR frequencies - some work in the near IR (or perhaps even somewhat into the Red end of the visible spectrum) - others in the far (...) (23 years ago, 14-May-02, to lugnet.robotics)

Typical remote control IRs like the RCX system are usually in the 870 - 950 nm range, just below visible red. A standard silicon CMOS camera chip will "see" this fine unless it has an IR cut filter (commonly installed in camcorders etc). Silicon is (...) (23 years ago, 14-May-02, to lugnet.robotics)

(...) It turns out to be the egcs 1.1.2 I compiled; the RPMs from sourceforge work fine. I'll try to find why my compiler was buggy... Thanks for your reply. Eric (23 years ago, 13-May-02, to lugnet.robotics.rcx.legos)

 | | General IR question
|
|
In general, what's the difference between the IR "signal" that the tower and RCX use to communicate and the IR energy used in thermal imaging? Is it just a matter of frequency? If the RCX was pointed at an IR camera, what what would it see? -- Dan (...) (23 years ago, 13-May-02, to lugnet.robotics)

2 ways that have worked for me, both using the long range IR mode: 1) Point the RCX's IR Port at the ceiling and your IR Transmitter/ reciever unit at the ceiling and bounce the signals off your ceiling. I have vaulted ceilings painted white and get (...) (23 years ago, 13-May-02, to lugnet.robotics)
