hbtest.c doesn't do anything by itself. you have to run the functions it contains at the IC command line; e.g., testmotors(); . walk thru the assembly instructions for info on using hbtest.c to test your board (URL). fred (...) (26 years ago, 3-Nov-99, to lugnet.robotics.handyboard)

| | Connecting two RCX's
|
|
Hello, I have two RCX bricks and would like them to co-operate without using the IR-Port. Is it possible to communicate by attaching a motor port of the first RCX to a sensor port of the second? As far as I know the motors work on 9V and the sensors (...) (26 years ago, 3-Nov-99, to lugnet.robotics.rcx)

Ralph, I agree with you. But I am probably in the minority. For me all LEGO sets are only parts packs for my own buildings. Gary Istok (...) (26 years ago, 3-Nov-99, to lugnet.build, lugnet.general, lugnet.robotics, lugnet.space, lugnet.technic, lugnet.trains)

I periodicaly search patents assigned to Interlego just to see what kind of stuff LEGO might be up to. I noticed this one granted in September on a communications protocol. I don't get into this level of programming detail and it might not even (...) (26 years ago, 3-Nov-99, to lugnet.robotics)

(...) Good grief! Maybe I should get involved in patent law (or at least spec'ing for patent lawyers). Honestly, the basic protocol that is described has been implemented LOTS of times in small proprietary projects. In fact, the fire alarm system (...) (26 years ago, 3-Nov-99, to lugnet.robotics)

(...) Actually, the sensors run on 9V too. Why would you not want to use the IR port to get them to cooperate? The "message" system built into them makes this the IDEAL way to communicate, expecially since you won't be tying up a sensor input or a (...) (26 years ago, 3-Nov-99, to lugnet.robotics.rcx.nqc)

I have only two significant gripes about TLG, and one of them occurs only sporadically: (1) The trend in macro-pieces (such as wall pieces, boat hulls, and columns) which replace with one brick what could (and should) be several smaller standard (...) (26 years ago, 3-Nov-99, to lugnet.robotics)

Here's where I really miss not having a digital camera. I'm working on a wheel-based 'bot that has rack-and-pinion steering, and I've run into a snag. (I realize that dual-motor steering and a caster-type rear wheel makes more sense, but I wanted a (...) (26 years ago, 3-Nov-99, to lugnet.robotics)
