| (...) I forget if I already replied with how nifty this is. I spotlighted it, I put in a news article at ILTCO (we're having some domain problems right now, a temporary url is iltco.northcomp.com) and I added it to the .trains header That ought to (...)

| (...) Sorry, my earlier post should have been more clear. I was just commenting on the fact that in general a resistor is _not_ a good way to reduce voltage to a train motor. And you recalled correctly: diode's are "one-way". Thats why you need to (...) (21 years ago, 29-May-03, to lugnet.robotics.rcx, lugnet.trains)

| (...) The problem with inductive load is that when current is interrupted, they generate large voltage spikes with reverse polarity. The diode absorbs these spikes and avoids destroying the driver... Philo (21 years ago, 29-May-03, to lugnet.robotics.rcx, lugnet.trains)

| (...) I'm no electronics engineer by any stretch-- A diode, iirc, allows DC current to 'flow thru' in only one direction. What would a diode do across the output on the top of the train motor? And why would one be good for 'inductive' loads such as (...) (21 years ago, 29-May-03, to lugnet.robotics.rcx, lugnet.trains)
