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)

Hi All, I just uploaded some pics of a new building, might take a couple minutes to show up. It's the one with the name that starts with "Earth".

What's wrong with the stock controller with both directions. Isn't that just a life lesson. And of course, perhaps, you can setup a pit crew behind the starting line (long live Death Race 2000!) ;D SteveB (...) (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)

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 (...) (22 years ago, 27-Jul-02, to lugnet.trains)
