Mark,
these builds are, as always, awsome.

Thanks, Mat!

One question, do the 4 outputs on the
quad conroller have a common return path on the controler? I.E. 5 output
wires or 8? Also, are the 4 outputs indepentantly conrolled or only 1 at a
time?
|
There are 5 wires for the lights. The common is positive voltage with respect
to the 4 output wires. Each light is independently controllable, you could even
blink them to simulate certain real world signal conditions.
Here’s a link to the DCC controller I used:

The picture shows how small it is. There’s also a link to a small PDF file with
wiring diagrams, etc...

I’ve yet to dive into DCC, but I’m curiouse to now what’s avalible.
|
Check out the rest of the site linked above, there’s lots of interesting
information.
| |
Do you plan to have these as part of a programed sequence, or indepentantly
concrolled by remote( seems a bit painfull with RCX)?
|
The goal is to use these for an automated layout. Right now, I’m controlling
the signals manually with the RCX remote control (which is a pain, like you
say). I’d also like to come up with software for semi-automated operation where
an RCX is used to sense if a train is in the track segment ahead and only gives
a green light when that track section clears. There are lots of ideas to glean
from the various DCC model railroading sites out there, so little time!
