Hi, I am lighting some hst 125 coaches. I am using pick-up from the wheels, with springs I have collected from old pens. I have used this idea before, and it works ok. What I would like to know is, should I be using a resistor from the bridge rectifier to the capacitor, or, just after it to the leds?. Also can anyone tell me the correct strength of the capacitor, bridge rectifier, and resistors I should be using. I am using dcc.
