Some Advice Needed on Benchwork

Benchwork - Roadbed

Hello all,

I am currently finalizing the plan for my future layout. It's not completely finalized yet, but the benchwork will be something along the lines of this configuration:

I would like to use foam as a subroadbed across the entire layout. Is this feasable?

Also, what construction should I use to support it? L-girders, frame, etc.

Need Some Arduino/LED Help

Fri, 2021-01-15 13:25 — Photo Bud

In my blog, on page 19, I describe a lighting project I'm working on.

As can be seen from code and description, 14 LEDs will be used, with two on each of seven pins. Assuming 18-20 mA each with a 470 ohm resistor per pair, this would exceed the 200 mA total for board. As I am anything but an electronic whiz, what would be the minimum resistor I would need to drop total amperage below that total?

Need some info

Does anyone know if the new style Athearn SD40-2 power trucks (ATHG63912) will still fit the old Blue Box SD40-2 frame?

NEW Athearn HO Scale Power Truck/HTC. SD40-2/40T-2/45T-2 (1) ATHG63912

Don't want to waste my money if they don't fit.

Thanks

Just ran across this video, ....pretty well done.

I went to high school in Aberdeen MD, home of Aberdeen Proving Grounds. There was one of these German guns there at the time. I think I may even have a model of one of these some where in my inventory.

I was about to pass on this one but then I realized I might be looking at the remains of an old popular Celebrity.

Prototype information

While perusing through a railroad trader site, I came across this dandy idea for old tank cars:
