I seem to have a lot of time on my hands so I decided to construct a country store for my little town of Burnley out on the Layout. This combines the basic construction method I’ve come up with using the CNC with some 3D printed detail parts I got off of https://www.thingiverse.com/
Everything is colored with rattle can spray paint and the details and sign were printed on my good ole HP Photosmart ink jet. Generous amounts of matte spray (clear) finish were applied to the structure and each of the posters and signs. It got it’s first steady rain last night and still looks crisp, we will see how hard the weather is on it over the next few months.
So here is the chicken crew. Mostly full grown. Two Roosters and 12 Hens. Have had no fox problems since I ringed the bottom of the pen with an electric fence. Should get about a dozen eggs every other day or so with all these.
Finished (more or less) my farmhouse cottage and a small barn. These will go into the Burnley area on my layout. The Barn needs some outside lighting and a few details, the house is all wired up but needs to have the windows frosted.
I did some more work on my servo controls for the Protothrottle over the holidays. I wanted to fine tune the live steam mode a bit more and clean up a few bugs. There are three servo modes- couplers, ESC and Steam. In the Steam Mode, Channel 0 is the throttle, Channel 1 is the direction. Both of these follow the direction and throttle controls on the PT. You can adjust high and low limits and reverse each servo. Here is a screen shot of my programmer:
The electronics are very simple, one board and a 3.7v lipo.
Here is a quick video of the servos on the bench:
Here it is fired up and running outside:
And a video of a complete run around the layout loop:
Finally got all the parts happy together. Ended up with a combination of several components I had not tried before- a Pololu 18v7 motor controller plus a relay for the lights. I had to add some code to the PT receiver but I think I will keep that as a configurable option from now on. I tried to use an old soundraxx sierra board but it just didn’t work very well. So I also added an old soundtraxx tsunami which gives the ooh-gah sound but unfortunately only diesel locomotive prime mover sounds. The speaker is a tiny 2 inch visaton-frws-5-r-2-fullrange-speaker, but it sounds pretty good.
Picked up a used rail truck for $75. Nice little fellow, all metal. Looks like it was modified by the previous owner to look like one of the old ‘goose’ rail cars from the 20s. I think that’s a bit of an overkill so I took it all apart down to the motor and cut out a new back end from sheet styrene.
