in some other thread, Mathias said: (...) I don't follow this. if 110 VAC (or some amount) goes in, it drops down to 9 (ish) i know for a fact that the RCX does not have a transformer, so the regulation has to be solid state..... ergo, somewhere in (...)

Wall current is not the same everywhere. It is not even always the same over time. I measured my wall voltage once, and it was 117. Now it's 120. Most wall wart adapters drop the voltage by a specific amount, so if the designers of a 9v adapter were (...) (23 years ago, 27-Feb-02, to lugnet.org.ca.rtltoronto)

(...) It's two "t"'s Mr. Mango :-) (...) My point here is this: I was using the Lego train transformer, which is just that: a transformer (10:1 ie. 120VAC in yields 12VAC out - no regulation, no filtering) If the voltage at the wall drops 8.3% (...)

(...) I am sorry. I was doing it from memory, and i thought I did so well by remembering the combination of "hias" that I forgot the easy part of Matt.

If you've ever wondered what newsgroup you're in on Lugnet, and you read "I dragged out my variac", you know you're in rtlToronto, because: a) People here have variacs b) People here know what variacs are c) People are not afraid to say they (...)

(...) Yes, but the overall plot arc is that you're all still trying to figure out why your ProjectXen didn't beat Rob or didn't function properly. And as we all know, rtlToronto's primary lesson is: Reality is Hard. Mario brings in our robot on (...) (23 years ago, 28-Feb-02, to lugnet.org.ca.rtltoronto)

(...) HI Everybody Why don't we just do it on the floor and have a line 12" after the finish line and you can't cross it or you're DQed. This is less risky and Lego won't go crashing onto the floor.

(...) Just a note about dragsters, having done them recently in SMART: I would recommend a very long track, and a very short stopping zone. EG: Track: 20 meters, and stopping zone: 20 cm, or perhaps even 10 cm. This definitely wouldn't be a 'night (...) (23 years ago, 2-Mar-02, to lugnet.org.ca.rtltoronto)
