 | | 4.5v upgraded to 9v - ideas welcome. —Chris Paton
|
| | | I would like to say "hi" and introduce myself as a LEGO Train newbie. I only have the old 7720 set and a load of track. Each time I think of upgrading and buying a new train set LEGO releases something new, usually Star Wars, which catches my eye (...) (20 years ago, 8-Feb-04, to lugnet.trains)

| | | | (...) I've done onboard RCX to modified train motor before. I had it read barcodes along the track to know what station to go to. (URL) motor now powers my DCC CN engine. One thing I would suggest is to get a 4.5 volt Zenner diode and put it in into (...) (20 years ago, 9-Feb-04, to lugnet.trains)

| | | | (...) Just remember to limit the current through the Zener diode when dropping the voltage... If you have a 12V supply and try to put a 9V zener without a dropping resistor, it will simply burn out. A zener diode is really a clamping device. Better (...)

| | | | (...) Well yes, that goes without saying. You need to protect your DCC function output from exceeding it's milliamp limit. With the Zenner it just makes your resistance required to be far less. As an example 50 ohms as apposed to 200 ohms. Dean (20 years ago, 9-Feb-04, to lugnet.trains)

| | | | (...) It's probably good to say it anyway... some of us on here don't know what end of the soldering iron to pick up (ouch! did you know soldering paste is NOT a good burn salve?) (20 years ago, 9-Feb-04, to lugnet.trains)

| | | | (...) Yes, I'm sure your right. I do plan on making up a page detailing my DCC related mods. But it's still too early to put it up as I'm still learning myself. :) Dean (20 years ago, 9-Feb-04, to lugnet.trains)

| | | | Hi Larry and Dean Thanks for the details guys. I think I will have to read the information from the webpages suggested before I begin soldering anything. But it is interesting to hear that basically anything is possible and that a solution to most (...) (20 years ago, 9-Feb-04, to lugnet.trains)

| | | | Hi again, I appreciated the advice I got last time I asked about trains, earlier in this thread, now I would like some more help. I have built a 6-wide MOC of what I hope resembles an EMD SD-90MAC Canadian Pacific locomotive using the old 4.5v (...) (20 years ago, 1-Mar-04, to lugnet.trains)
