| Hi Blakbird, Little note about 4.5V motor: when you say "The motor is DC, so polarity is not important."... precisely since it is a DC motor, polarity IS important, rotation direction depends on it... Philo (17 years ago, 21-Dec-07, to lugnet.technic, FTX)

| (...) Eric, this is a fantastic resource you are creating. I can't wait to see further updates - even if for some of us what you write is common knowledge, it still makes good reading and I always find something new to appreciate. As a side note, (...)

I actually used to have one that I got in a sealed box (!), and when testing it with a train speed regulator (12V grey (...) (17 years ago, 22-Dec-07, to lugnet.technic, FTX)
