  RE: latest legOS strangeness
 
(...) Interesting question. I'll try this at home with my remote and RCX loaded with standard firmware. Anyway, that could only say that the remote control knows that it has to send a OFF (brake) cmd to the RCX when fwd and rev are pressed together, (...)

  Re: Powering motors from the mains
 
(...) I'd be a little surprised at a bridge rectifier which couldn't accept DC. Many electronic appliances have them these days so that it doesn't really matter what kind of wall wart you use, so long as the voltage is in the right range. The wall (...)

  Re: Powering motors from the mains
 
(...) Yes. That is what I meant. I even believe sincerely that it's what I said. :-) I am not sure who exactly within LEGO first recommended it but if you dig hard enough in lugnet.robotics I believe you will find just such a recommendation.... that (...)

  Re: Powering motors from the mains
 
I think you misuderstood what Larry said (or I misunderstood what you said). I think Larry was saying that you should use the wall wart from the train speed regulator, which is what Lego recommends. Also, I dont see how you could burn out the diodes (...) (23 years ago, 18-May-02, to lugnet.technic, lugnet.robotics)
 
  Re: Powering motors from the mains
 
Those who can use a soldering iron, and know their anode from their cathode, could build something like what I did: (URL) black box is a 7809 9v positive voltage regulator. See the data sheet here: (URL) used a 12v wall wart to power the whole (...) (23 years ago, 18-May-02, to lugnet.robotics)

  #9701 Control Lab building set with RCX's
 
How many RCX's and what software do you need to control the Vending Machine requiring 4 sensor input ports and 5 output ports at Brickshelf's (URL) it require RCX to RCX or Scout communication, e.g., Robolab mail?

  Re: Powering motors from the mains
 
I have the RCX 2.0 and it doesn't hace any power connector. Lego should have thought about that and at least sell a special adapter. Anyway, they didn't. ----- Original Message ----- From: "Larry Pieniazek" <lpieniazek@mercator.com> To: (...) (23 years ago, 17-May-02, to lugnet.robotics)
 
  Re: Powering motors from the mains
 
(...) You can do this but it's not recommended. As the RCX 1.0 has a bridge rectifier on the power input, it's recommended you use a 10v AC supply, to avoid buring out the diodes. ROSCO (23 years ago, 18-May-02, to lugnet.technic, lugnet.robotics)

Duncan, check out my website www.snoozysplace.be.tf You will find the latest version over there, and also my emailadres where you can ask me for the password. btw, English isn't my native language, so what does "elusive bloke" mean ?

  Re: What is exception "StackOverflowError" in method "<clinit>"
 
(...) StackOverflowError could either be a stack overflow (maximum depth is 10) or a thread that dies from whatever exception (that seems to be a bug, but I couldn't yet figure out what causes it). I suppose TextLCD.print should work, though I never (...) (23 years ago, 17-May-02, to lugnet.robotics.rcx.java)
 
  Re: Powering motors from the mains
 
(...) No, they didn't, that was just a rumour. You can power an 1.5 or 2.0 RCX by connecting a _regulated_ 9V DC supply to the battery connectors (with the correct polarity of course). To power 3 stalled motors I think you need around 1A (not quite (...) (23 years ago, 17-May-02, to lugnet.robotics)

  Re: latest legOS strangeness
 
(...) I may be wrong - 'my' RCX is actually my brother's, and is 3 hours drive away - but doesn't the remote control with the official firmware do float when buttons released, but brake if forward and reverse are pressed together? Max (23 years ago, 17-May-02, to lugnet.robotics.rcx.legos)
