(...) Yes - that'll also make the algorithm run faster. (...) I'm sure it's possible. What I'm not sure about is whether the kind of naive algorithm that I could come up with after just a few minutes thought would be effective. It might take some (...) (23 years ago, 18-Dec-02, to lugnet.robotics)

I have not performed any tests, but if you go in configuration panel, you will see that the USB tower can't be put in long range mode if it is placed behind a passive (non powered) USB hub. That may also be the case for low power laptop usb ports. (...) (23 years ago, 18-Dec-02, to lugnet.robotics)

Thanks for replying! I was thinking of the same procedure. But to help with the varried depth problem, a small part of the viewed area could be selected to be the focusing point. So overall, it must be possible, right? Timothy (...) (23 years ago, 18-Dec-02, to lugnet.robotics)

I have one of each RCX (1.0, 1.5 , 2.0) and have tested the signals using a palm app called IRMonitor with little or no difference between the three. This is by no means a "labratory test". Haveyou noticed this with more than one brick? For the (...) (23 years ago, 18-Dec-02, to lugnet.robotics)

(...) Well, I'm not an expert - but I imagine it should be possible to produce a measure of how sharp the image is. For example by adding up all the differences between one pixel and it's neighbours. In a sharp image, you'd expect a lot of nice high (...) (23 years ago, 18-Dec-02, to lugnet.robotics)

Anyone got the USB IR tower shipped in 2.0 to connect to a linux box? If not, are there any specs available so that I can write one? Thanks, Brian Palmer (23 years ago, 17-Dec-02, to lugnet.robotics)
