|
| Our club lets kids run the controller for one of the lines when we do certain events (like, right now, with Detroit Festival of Trees), but we could use a way to forcibly limit the speed on the line that they're allowed to run. One way that's really (...) (15 years ago, 23-Nov-09, to lugnet.trains, lugnet.robotics)

| (...) I think this is how you want to do it. A simple solution would be to go to Radio Shack, and buy a couple large ceramic resistors. (not sure the values you'd want, but something low). Then, take a normal 9v wire, cut it, and insert the (...) (15 years ago, 23-Nov-09, to lugnet.trains, lugnet.robotics)

| (...) Years ago PNLTC used to do this for the kids table at the show. From what I recall, we just drove a screw though the controller at about the 4th notch in the black area on each side to keep it from turning too far. It is a very long lasting, (...)

| (...) Hello, you can put AC or DC voltage at the input of the regulator with no problem as long as you don't put more than 9VAC~14VDC. The internal circuit will take both. So a quick fix that put 4.5~5V DC at the input will ouput about 3~3.2VDC at (...) (15 years ago, 23-Nov-09, to lugnet.trains, lugnet.robotics)

| (...) You have to be careful here. The controller is designed to take AC or DC, but the input diodes that that convert the AC to DC are only rated for 1 Amp (1000 milliampres). Make sure your transformer/wallwart is not rated for more than this. (...) (15 years ago, 24-Nov-09, to lugnet.trains, lugnet.robotics)
