Hey Esger
I'm not an electronic specialist by any stretch of the imagination (though not
by lack of trying)
But commercially available DCC controllers and stuff mostly run at 12 volts
(from the research I read), but the RCX runs at 9 volts, either by batteries or
by the AC adapter. So if the RCX is actually being the DCC controller, wouldnt'
there only be 9v going out to the track? The instructions talk about putting
the 3 motor outs in parallel, which would still make the resulting output at 9v
(with alot more amps).
So the power out on top of the motor unit would be also 9v so we wouldn't need
the resistor or diodes in the first place... I think.
Anyway, thanks for the input.
Dave K
