"Portable" Layout Table

Sat, 2012-02-25 09:29 — HOBen

I am building a 4 X 8 layout that is located in a spare room in our house. One day I know I will have to give up this room to be used for another purpose. To make moving the layout possible, I knew I would have to build it to come apart. Here is what I have done to make things easier on myself.

Effect of filter caps on DC voltage

Fri, 2012-02-17 16:14 — ajcaptain

I have a DC bus on my layout that tests out at 13.3 volts.  I added a 2200uf 25 volt filter capacitor across the + and - terminals, and this seems to be causing the DV voltage to jump to 19 volts.  

Can someone tell me what might cause this?  Am I better off removing the cap?  I'm going to be running a bunch of led's off this bus, and they are very sensetive to voltage.

Any input would be appreciated.

Thanks,

John

Next step for battery power ?

Tam Valley Depot is working on a new system for battery power using existing DCC equipment:

Walthers Crossing Signals

I was wondering if anyone has tried these out at all, and what they think.  I have a set, but I am looking at getting another for my railway.  Are they good, or should I look else where?

MRC 6200 needs circuit protection

Thu, 2012-01-26 18:28 — nrandel

The club has an old MRC 6200 DC cab and the throttle doesn't work - engines run full speed.  The cab I found out doesn't have any overload protection and what I read is the D1230 diode(s) have been shorted out.  When I change these diodes out is there a way I can protect this from happening again?

Phoenix sound systems

I have installed a Phoenix sound system in my G scale shea. What I need to know is what type of cable to run from my computer to the port on the engine

Timesaver - event counter rather than timer

Fri, 2012-01-20 10:18 — steamerjohn

I'm building a John Allen Timesaver layout, using DC, for a friend recovering from an illness. I'm looking for an inexpensive (buy or build) electronic counter that is resettable and will increment each time the loco changes direction, as an alternative to the stopwatch. Many decades ago I built Heath Kits, so a list of Radio Shack components and simple "non-engineer"  instructions/pictures should work for me. Planning&nbs

Old School

So this might shock a few people, but I'm going old school DC block control on my new NScale layout. I don't have the cash to invest nor do I want to try and convert all my locomotives to DCC. I kind of like flipping the switches on a dual cab setup anyway.

Signals built from Scratch

Thu, 2012-01-19 08:27 — Bernd

Reading HOBen's post on signals brought back some memories of when I first scratch built my first signals about 15 years ago. Not wanting to hi jack HOBen's thread I thought I'd start this one.
