Lego is usually pretty nice about replacing broken lego, far nicer than they are required to be. I dont know what theyll do about a broken RCX though. You should call consumer affairs (i dont know the number) and ask them. (...) (23 years ago, 16-Feb-02, to lugnet.robotics)

You didn't indicate whether it is an old-style 1.0 RCX (external adapter) or not, so I'll asume it's a batteries-only unit. First of all, do you have any experience with electronics? The first thing I'd be looking at after a mechanical shock would (...) (23 years ago, 17-Feb-02, to lugnet.robotics)

(...) Definitely. I was having problems with my light sensor (this was before I was using legOS) - the 'test panel' in the Mindstorms software wasn't reading it, and the RCX just showed a boolean 1 on the light sensor port. So I called LEGO, and (...) (23 years ago, 17-Feb-02, to lugnet.robotics)

(...) Also, there can be contact problems between the tabs and the circuit board. They are not soldered on, they only press against two square contact areas in the corners. If they are a little bent they can loose that contact, which happened to my (...) (23 years ago, 17-Feb-02, to lugnet.robotics)

I saw your post on RTLToronto.... You didn't indicate whether you tried to use batteries again afterward. I'm assuming you did. I'm also assuming you hooked the terminals up backward. That could be trouble. The 7805 regulator will protect the (...) (23 years ago, 18-Feb-02, to lugnet.robotics)

I applied power to the last capacitor towards the back...and it works!!! Should I connect to this capacitor using a fuse or anything first or is it safe to solder leads directly from this capacitor? thanks -----Original Message----- From: (...) (23 years ago, 18-Feb-02, to lugnet.robotics)

Hello Matthias, thanks for a very detailed description of your findings inside the RCX. I have just one comment to add ... (...) True, as long as we are talking Alkalines. But how about NiCd accumulators? I think they can deliver much higher current (...) (23 years ago, 20-Feb-02, to lugnet.robotics)
