| I appreciate all your suggestions. Is there a website you can suggest that has more information on this stuff? Also, beside Jameco, what are some othe good places to buy parts? Thanks, Tom (16 years ago, 25-Oct-08, to lugnet.trains, FTX)

| (...) Hey Rob, It would be safer to place a regular doide in series with this if the voltage is going to be reversed some of the time. But the circuit shown in the link handles reverse voltage up to 9v fine. The LED acts as a reverse protection (...) (16 years ago, 24-Oct-08, to lugnet.trains, FTX)

| (...) Great idea. I hadn't thought about whether Tom was going to use a variable speed control. I just assumed batteries for some reason. Have you had any brightness issues with the seemingly low 15mA output for multiple LEDs or are you hooking 1 to (...) (16 years ago, 24-Oct-08, to lugnet.trains)
| | | | | Re: Need Electrical Help

| (...) If the voltage is going to vary, don't use a resistor as current source, consider a current regulator instead. That way the LED stays brightly lit over a wide voltage range without getting burned out at max voltage. This works for one or more (...) (16 years ago, 24-Oct-08, to lugnet.trains)

|
| Our train group is going up to 6-wide cars (and 8 wide trains) for the next layout. Anyone got any advice or tips on how to make them (and how to make them look good)? I am good at making 4-wide cars but not so much at making 6-wide. (16 years ago, 22-Oct-08, to lugnet.town, lugnet.trains)
