I noticed that Toys R US in central Ohio have deeply discounted Lego Znap products. I bought a 3552 for $9.97 in Columbus (Hamilton Rd) last week. Today I picked up models 3552 and 3571 for $4.90 each at TRU in Heath! Each includes a 9V motor (...) (25 years ago, 9-Oct-00, to lugnet.robotics)

I have sneaking suspicion it has something to do with the fcc and the use of the 27MHz model control band. As I understand it, use of the 27MHz band in the US specifically prohibits the transmission of data, while it isn't so stringent in this (...) (25 years ago, 9-Oct-00, to lugnet.robotics)

Thanks for the info Steve! I've read a little about NQC and LegOS and as you describe LegOS appeals to me for the raw low-level support it offers. (...) What do you mean "setup as a cross-compiler"? I'm not familiar with that process... Is there a (...) (25 years ago, 9-Oct-00, to lugnet.robotics)

I have been keeping an eye on this thread and feel compelled to add my observation and experience; The touch sensors tend to exhibit quite an extended range of resisitance values as they are depressed. I have a couple which start as high as 7k on (...) (25 years ago, 9-Oct-00, to lugnet.robotics)

(...) Well, (I'm also a C++ programmer - with a similar background - who got a RIS for his birthday this year). There are two choices that suit people like you and I. The *simplest* is 'NQC' (Not Quite C) - which is a *small* C subset that compiles (...) (25 years ago, 9-Oct-00, to lugnet.robotics)

Hi, I am new to Lego Mindstorms and just got a RIS 1.5 for my birthday. Let me start with a brief background info on myself: By profession I'm a C++ programmer who does COM+ development. I'm not a formally educated computer scientist however (no CS (...) (25 years ago, 8-Oct-00, to lugnet.robotics)

Amnon: Thanks. Your right. that did the trick. I used your idea in conjunction with a part that I found in the cybermaster set. I just searched the element registry and could not find it. it has 2 friction pegs on the bottom, and forms a triangle (...) (25 years ago, 8-Oct-00, to lugnet.robotics)

| | Resistances of touch sensors and lamps
|

Hi all, I played around with touch sensors and a lamp this weekend, trying to measure their resistance. Since my Ohmmeter proved rather unreliable, the values keep wandering around and it seemed zero was not well adjusted, I just took a look at the (...) (25 years ago, 8-Oct-00, to lugnet.robotics)

can the IR port used to send messages to the RCX also be used for other applications? in other words should i even bother trying to use the IR module hooked up to my computer for other devices or should i expect it to be proprietary. and if it is (...) (25 years ago, 8-Oct-00, to lugnet.robotics)
