The ink appears translucent on a dry-erase board or projector because the surfaces being written on do not absorb the ink. Has anyone tried washable crayons on one of those boards yet? (URL) Message----- From: Mike Reddy [mailto:mreddy@glam.ac.uk] (...) (23 years ago, 5-Jul-02, to lugnet.robotics)

This is an interesting aspect of using two RCXs. My only experience is with NQC and the single byte "Message" function, but I have succeeded in making the communication link bi-directional and reliable. I simply create a process in the "master RCX" (...) (23 years ago, 5-Jul-02, to lugnet.robotics)

I've been working on just such a robot. (two RCXs, two rotation sensors, four light sensors, and two touch sensors) Currently, my biggest problem has been communicating between RCXs. I keep getting collisions with my messages. I've had to limit the (...) (23 years ago, 5-Jul-02, to lugnet.robotics)

(...) OK. Two factors here: 1) Status of pens - colour, newness etc. Reflectance of the base surface - glossy, etc. I am using a white board for my playing surface, which is quite reflective. Furthermore, dry wipe pens are translucent - otherwise (...) (23 years ago, 5-Jul-02, to lugnet.robotics)

Hello! I'd like to use leJOS on linux but it seems not so good support for usb IR tower, so I'd like to get one IR serial tower like the one from RIS 1.0/1.5, as no parts' sales in HK. Can anyone tell me what should I do? Rgds, Laurence (23 years ago, 5-Jul-02, to lugnet.robotics.rcx)

(...) With the default CONF_LNP_HOSTMASK (0xf0), the host adress is encoded in the higher 4 bits, so you should write #define CONF_LNP_HOSTADDR 0x10 Eric (23 years ago, 5-Jul-02, to lugnet.robotics.rcx.legos)

I have chased this topic around quite a bit in the last couple of years and built a few prototype devices to perform "I/O expansion". My final conclusion, having gone to the trouble of building a device which permits two of the RCX motor ports and (...) (23 years ago, 5-Jul-02, to lugnet.robotics)

Hi, since a few hours, I'm trying to give an RCX another LNP_HOSTADDR - so I changed the appropriate line in boot/config.h from #define CONF_LNP_HOSTADDR 0x00 //!< LNP host address to #define CONF_LNP_HOSTADDR 0x01 //!< LNP host address and compiled (...)
