February Progress Update

I’m a little surprised that it’s been over a month since the update video! Looks like I should be getting the camera out again. Progress has been slow, and not always photogenic, but there have been a few changes worth reporting on in the last six weeks. Lots of “real life” things going on right now that are keeping me from moving forward, but even slow progress is progress!

This post will be something of a mixed bag of content, since there are several different work items going on, and I feel I need to get the blog caught up quickly.

Structure Mock-Up

First up, this is a construction paper mockup of the Commonwealth Paper Products structure that will be on the narrow shelf behind the entry door.
Commonwealth Paper

I drew the building structure in SketchUp, and then printed 2D views of the model to glue onto a core that I built from cereal boxes. I think it’s a pretty convincing stand-in, and I plan to do these for many of the structures on the layout.

Custom Electronics

Next we have a couple of different electronics projects… a trio of CDU-based Kato turnout controllers that I built for a friend, and the completed control circuit for my animated swing gate.

Kato Crossover Controls

The CDUs are based on an integrated design I have that incorporates a switch and indicator LEDs, but my friend wanted to mount these remotely from his control panel, so I provided connectors for the switch and LED. These are a very simple design (not mine, just adapted), and the selected capacitor is powerful enough to handle a double crossover.

Stepper Motor Control

The swing gate control board has screw terminals for all of the motor, sensor, and control connections, and sockets for an Arduino Pro Mini and a stepper motor driver. This is ready to hook up, once I solve the mechanical issues with connecting to the shaft of the swing gate itself.

New Power

CXST1141 Atlas MP15DC

This is the latest addition to the power roster, an Atlas MP15DC that I bought second-hand from a friend and that will be used in the yard. It’s DC for now, but I will upgrade it to DCC soon. I’ve tested it on the branch line, and it runs quite well.

Dixie Cup Factory Model

I’ve built up a SketchUp model of the Dixie Cup factory as well…

New Lighting

Finally, I replaced the ceiling fan in the room with a much, much brighter 4-tube fluorescent lighting fixture with 5000K daylight tubes. It’s almost too bright in here now!

New room lighting

As part of the lighting upgrade I also moved the wall switch for the room down below the layout deck. The “standard” switch location was behind the backdrop and would be impossible to reach once scenery was in place.

New room lighting

The new wall switch incorporates a very convenient outlet that will help with working on that part of the room.

That’s all for now! I have some track laying progress to report, but I will include that in a separate post after I take some better pictures with the new lighting.
