  Re: events or infinite loops... which is better?
 
(...) Events are generally going to be more efficient since no bytecodes need to be executed to continually check for a condition. However, efficiency is not always the most important factor. I don't think either one is necessarily "better". A lot (...) (23 years ago, 12-Oct-02, to lugnet.robotics)
 
  Re: More Battery Questions
 
Replacement battery options are listed on the HB FAQ, at: (URL) don't you get the 1000 mAh packs from Radio Shack? That would give you 2x the run time of the 500 mAh packs. Take longer to charge, but would require no other board mods. Fred (...) (23 years ago, 12-Oct-02, to lugnet.robotics.handyboard)
 
  Re: Starting Over
 
(...) The BrickOS for cygwin instructions ((URL) describe downloading the source code for gcc & binutils and building the Hitachi cross-compiler and associated tools in step 2.

  Starting Over
 
Hello, According to John Hansens' instructions, I am assuming you do not need to download the bin-utils as called out in the original sourceforge instructions. Is this correct? Thanks again for the help. Here goes. Rick Bonari (23 years ago, 11-Oct-02, to lugnet.robotics.rcx.legos)

  events or infinite loops... which is better?
 
Hi Everyone, I just recently learned how to use event monitoring, and I really like it. My question is whether or not this method is more efficient than infinite loops. I always used to check for sensor readings using an infinite loop something like (...) (23 years ago, 11-Oct-02, to lugnet.robotics)
 
  Strip Command
 
Hello, When I do a uname command, I get CYGWIN_98-4.10. It definitely appears that makefile.common has some problems with paths, etc. When I type the command: strip fontdesign.exe dll.exe makelx.exe fixdeps.exe genlds.exe firmdl3.exe as I mentioned (...)

  More Battery Questions
 
Hi, First I wanted to thank the handful of people that responded to my previous question about HB batteries. We seem to be getting by using Fred's suggestions, basically being more careful about charging, using ZAP mode to pull up really dead packs, (...)

  monitor and control external voltage
 
Could you build a voltage controlled switch out of the RCX? Do this: Monitor a voltage, when the monitored voltage does something, switch a motor output. 1) What would you have to do to monitor a voltage (safely)? Connect an input sensor to your (...)

  Re: RCX and GPS systems
 
(...) It might be possible to run an IR transmitter directly off it, IIRC John Barnes posted a circuit diagram for that a while ago (he might also sell these things). Then you only need the software, where you need to send/receive single characters, (...) (23 years ago, 11-Oct-02, to lugnet.robotics.rcx)
 
  BrickOS issues
 
First off, I'd like to say that I had ZERO problems installing, building, and testing BrickOS on my PC. That's even with the BrickOS name change release and the pre-built Hitachi tools.

  Re: RCX and GPS systems
 
A big question is if the positioning resolution you could achieve would be worth the cost or effort. The GPS hardware I've seen tell you where you are within a few yards. Unless you can get that down to a few inches what's the point? Plus you still (...) (23 years ago, 11-Oct-02, to lugnet.robotics.rcx)
 
  RCX and GPS systems
 
For sometime I have thought that a GPS interfaced with the RCX would be the answer to my navigational prayers. I have not found any information on an interface for the RCX (GPS-RCX or GPS-PC-RCX). I realize that this is not a trivial task with (...) (23 years ago, 11-Oct-02, to lugnet.robotics.rcx)
