(...) I think using your logic you should subtract the cost of the Gameboy, because, hey, it's a gameboy. I wouldn't mind having one. Then the XRC is $269. Andy (20 years ago, 17-Jun-04, to lugnet.robotics.rcx)

(...) Oh, yes it does. Quite a bit more, actually. The original GBA still runs about $70, I believe, or the GBA SP will hit you for $100. $269 gets you both the XRC and the basic no-frills Xport that connects it to the GBA ($338 will get you the (...)

(...) I did a little online research and found a website that claims the "omni-wheel" has been around since 1910, and the people who built the robot were nowhere near 90 years old. It's been a few years since I saw that episode, but I think it must (...) (20 years ago, 16-Jun-04, to lugnet.robotics.rcx)

(...) I had a good look at this - it does not cost much more than the RCX (although you need other stuff and motors to use it). The non-protected boards could be got around with some good Lego construction. Since I sometimes use custom boards with (...) (20 years ago, 16-Jun-04, to lugnet.robotics.rcx)

(...) The biggest problems I see with this are that the boards aren't protected. The odd thing is that they're not mentioning the extra battery capacity as an improvement over the RCX. I thought it would be a big problem to drop from 3AA to 2AA in (...) (20 years ago, 15-Jun-04, to lugnet.robotics.rcx)

These guys have a robot controller that replaces the RCX that uses the gameboy as the main processor www.charmedlabs.com I'm thinking on getting one. I called them yesterday. Very nice guys. It won't ship until the end of June though :( Andy (20 years ago, 15-Jun-04, to lugnet.robotics.rcx)

Of course, to do that (I'm always thinking in LTC display mode) requires a hill to go with it. I didn't see whether (...) (20 years ago, 14-Jun-04, to lugnet.robotics.rcx, FTX)

(...) I think it's theoretically possible to communicate an 8 state signal from the RCX to the Cybermaster's passive sensor port. The passive sensor port measures resistance as well as using a switch - the 3 switches in the cybermaster set have (...) (20 years ago, 11-Jun-04, to lugnet.robotics.cybermaster, lugnet.robotics.rcx)

(...) This might be old news, but I just tried it anyway... You can connect an RCX motor port to a CyberMaster sensor port and vice versa and get tri-state info. You can distinguish between the motor floating, off, and one of forward or reverse (...) (20 years ago, 11-Jun-04, to lugnet.robotics.cybermaster, lugnet.robotics.rcx)

Is it possible to interface a cybermaster and an RCX without the use of a PC, also without using up all sensor and motor ports? Sincerely, Morten H Pedersen (20 years ago, 10-Jun-04, to lugnet.robotics.cybermaster, lugnet.robotics.rcx)

Hi, That's odd. I upgraded mine from 1.0 straight to 2.0, and I only paid for the shipping. I did not order online, but on the phone. As far as choosing between Robolab and the RIS software, it depends upon the age and motivation of the child. (...) (20 years ago, 7-Jun-04, to lugnet.robotics.rcx)
