| | | Sonnich, Nice site, good info. I want to figure out how to keep the controller from going in reverse, I just want it to only go forward no matter which way the knob is turned. Any clue on how do this? jt (...) (22 years ago, 26-Jul-02, to lugnet.trains)

(I'm not an electrical engineer, but I remember something about a rectifier allowing current to pass "one way"... And I think I know exactly what (...) (22 years ago, 26-Jul-02, to lugnet.trains)

| | | | | | We have been experimenting with an external bridge rectifier for our Rail Racer events. The only drawback is that the one we picked out (lack of electronics experience) draws 1.5 volts away from the output going to the track. Not a big fairness (...)

| | | | | | | It would nice if we could just reverse some of the circuit instead of having to use a rectifier (something about that word makes me laugh). Nice tag line Rob. jt (...) (22 years ago, 27-Jul-02, to lugnet.trains)

| | | | | | (...) You probably used one with regular diodes, where each diode gives a 0.7 voltage drop, which is standard. You could try Skottky diodes which IIRC give a 0.3 voltage drop each, leaving you with 8.4v. Other way would be to use some transistors (...) (22 years ago, 27-Jul-02, to lugnet.trains)

| | | | This looks a little complicated, teh inner port of the circle is the switch, but it also connects to the outer part, so you cannot just rewire it. And not using that part will cause to have power out at all times (which I guess is 1.25V, I donne (...) (22 years ago, 28-Jul-02, to lugnet.trains)
