Been clearing down my inbox and stumbled across these – how I missed them first time round is beyond me.
I didn’t tell you, but I’ve been working on my lighting.
Theater gels on fluorescent tubes in the diorama soffit, dimmers on the incandescent spots, and a small planetarium for my celestial effects!
Obviously the moon isn’t exactly to scale, but I can make it appear to rise from behind the mountains, and I’m working on the optics to make it smaller.
A little “over-the-top,” but sort of a cool effect, don’t you think?
Thank you for your daily blog, which is a real service to the model rail community.
I have attached details of a way to change a simple 2 aspect, red/green led signal using contacts on a points motor. As there are only two wires from the led signal this can be a real challenge. I hope this helps others that may have encountered this difficulty.
The Problem: How to use Gaugemaster SEEP points motor PM 1, to switch Gaugemaster SEEP 2 Aspect colour light signals from red to green etc, when ONLY 2 wires are present from the light signal unit and you would normally need 3-4.
You need to change both the positive and negative to each coloured LED and this is normally achieved manually by the supplied manual crossover switch with the light unit.
However to achieve this automatically by using the contacts on the points motor is a challenge.
The Solution: Shown below is a low tech proposal using 2, 9 v batteries. The red and green LED are in effect using one battery each to provide the required polarity change when the points change.
The thicker line shows the current path at each change over.

Joe’s been in touch with his progress (his last post is here).
“Hi Al; Thanks for putting up the pics.
Here are some more “construction” pics.
The layout is a ‘free lanced’ 1940 – 1950 steam era set roughly in the “town” of San Juan Creek in N.W. New Mexico.
The main industries are coal mining and lumber.
I can’t tell if I already sent these. IF they are duplicate, please discard.
Laying roadbed. Elevation for inner main line completed. 2.75% grade.
That’s all for today folks – a big thanks to Fred and Eric (better late than never, chaps).
Please do keep ’em coming. If there’s anything you want to share just hit reply to any of my mails.
(You can send as many pics as you like, but please don’t send more than 3 pics per mail – send as many mails as you like…)
And if you’re enjoying the posts, don’t forget there are hundreds and hundreds more with the Beginner’s Guide.
