|
| (...) Excellent video, Sivan - I can see this is fun to play around with. I have to admit that I was as of yet unaware of the power functions system. While I figure that an RCX with IR remote and some decent design work might also be quite (...) (17 years ago, 22-Dec-07, to lugnet.technic)

|
| I uploaded a video (with some stills in it) of a Power-Functions remote controlled car. It uses a dual-differential drive so that it can go straight well. (The video also shows stills of an earlier version that used a more conventional steering; but (...) (17 years ago, 22-Dec-07, to lugnet.technic)

| (...) Just by the way, back in those days LEGO also made a 12V technic motor that was the same size as the 4.5 but came in black. 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)

My goal here is to put a lot of that knowledge together in one place. I am certainly (...) (17 years ago, 21-Dec-07, to lugnet.technic, FTX)

| (...) By the way, I noticed that your site only looks at the 9V motors. Have you ever dissected or tested one of these 4.5V motors? Eric (17 years ago, 21-Dec-07, to lugnet.technic, FTX)

| (...) Good point, Philo. I did not choose very good wording here. What I meant was that, as a DC motor, there is no "hot" terminal and no "neutral" terminal. Therefore, you cannot hook it up wrong and damage it. I'll go back and see if I can clean (...) (17 years ago, 21-Dec-07, to lugnet.technic, FTX)

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, (...)

| 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)
