 | | LEGO Capacitors use on Trains? —James Trobaugh
|
| | | Has anyone tried using one of these new Dacta LEGO Capacitors on their trains? Seems like this would be a good way to keep the head lights bright even when the train slows down. "(URL) might have to buy one and try it out. jt ----- James J. Trobaugh (...) (24 years ago, 7-Feb-01, to lugnet.trains)

| | | | | (...) How would you wire it so that it would only light the light? I would think that it would try to drive the train at the same time... Of course, that might be an interesting way to make the train more "speed realistic" - it would gain speed more (...) (24 years ago, 7-Feb-01, to lugnet.trains)

| | | | | | (...) You'd have to use a diode. Trust me, it is very unlikely that the cap would be able to deliver much in the way of power to drive the train (they only hold a few joules of energy, not much when compared even with the speed of a Lego train). I (...) (24 years ago, 7-Feb-01, to lugnet.trains)

| | | | | | oups! don't try it or be very carefull. the capacitor is a 1Farad 3Volts max capacitor. that would limit the voltage that you can put your regulator at 3V. If you go past that voltage, you'll end up blowing up your capacitor (quite a messy situation (...) (24 years ago, 7-Feb-01, to lugnet.trains)

There is no good solution, unless you want to run your train at full speed for interval period in order to charge a big capacitor at 8-9Volts, then reduce the speed of the train and let the capacitor feed the ligth. Using that method the ligth (...) (24 years ago, 8-Feb-01, to lugnet.trains)
