The limiting factor here is controlling the amount of current / amperage through the Arduino. They are not good at anything that will pull a load through the board. Your note of using an H Bridge...

I was recently ask if I could laser engrave replacement end walls for the Walthers kit that reproduce what the Northern Pacific Railway did for window arrangements. While very possible, matching...

You may be running into a consist number instead. Try tapping on the consist button and delete any consist number shown.

As for auto reverses, I have a pair of reversers from MRC that work well...

Phosphor bronze sheet, cheap at less than $8, easily cut with scissors and bent to shape....

Wanted to try using chalk based black and white paints mixed with my weathering colors to produce a more flat and finer finish. Yes, I use cheap acrylic craft paints for weathering because they are,...

Put your equipment in a location that is easy for YOU to work on it. If it's buried under the layout and hard to get to, you'll not want to touch it. I have a small closet space that my track...

This may be a case of painting the whole thing in a neutral stone color, then picking out individual stones with a varied shades of your earth tones you want to use, then 'mortor' it afterwards. ...

I have had problems with all the putties simply not sticking to the plastic surface, and when they dry, they still curl up and pop off. I've heard it can be useful to squeeze out an amount into...

Did you ever make any plans for when you have to move and take this layout apart? Planned seams, casters, whatever might work for you to allow you to move this to a new place when you move.

I'm a sucker for hobby tools and had no resistance to Buy It Now. Will be curious to see how this compares to chisel type scrapers from Tamiya.

I collect back issues of MR, RMC, N-Scale, etc because information doesn't cease to be useful just because it is old. I love leafing through old issues and usually find some nugget of information I...

No clue this narrow gauge line existed. Just looked over the map and see the old line, but not where it would have joined to a pier. Still, curious and intrigued. That would be a nifty small line...

I use these:

They were available from, um, me. I made them. Something I hope to offer online and at local shows.

And I'm STILL trying to clean out that damned clogged airbrush!

But seriously, I've been buying up cheap units from Amazon and having learned how to tune them watching YouTube videos, have...

I have the advantage of a laser cutter that handles 1/8" plywood quite well, so making racks for paint, tools, and supplies is handy. I bought up a bunch of styrene bundles at railroad shows and...

The trend is to have peel and stick trim. I'm not a convert on this fully as I don't know if the adhesive will give up later. Yes, it's good quality 3M stuff, but we're using it in ways it was not...

I enjoy building reviews like this. I'm designing laser kits now for some simple structures and I learn from what builders do with them. I may have to send some samples to be built like yours to...

Isn't this turntable the same Heljen/Concor model that has been around since the 70's in one form or another, rebranded many times?

The mini table saw from Harbor Freight has absolutely no torque so cutting anything other than balsa is pretty near impossible.

I haven't tried the tiny chop saw, but don't have a need for it. ...

When I visit Home Depot / Lowes, I only see white grout, and totally miss the colored stuff. Am I looking in the right place? I could really use some variations in color base for industrial versus...

With Sunday and Monday off to spend on the layout, I hope to finish one dual grade crossing and patch the scenery in there, then see about striping an 8 foot long length of two lane highway. IF I am...

Won some auctions. Scored well on three (possibly a fourth in a partially hidden bag) Nn3 Republic Locomotive Works conversion kits, a Marklin chassis, extra wheels, etc. Should be enough to do at...

I liked this idea enough, but was concerned about heat and the resin or filament. Decided to go with model plywood and a bit longer so the rails had some length to them for good grip. Turned out to...

How does the PLA hold up to the heat of repeated soldering? Does it soften or lose alignment? Do you think resin printing might work better?

I've got several printers and might try the file with...

Finding printable 'regular' vehicles instead of show case cars or muscle cars is hard. Try to find a 70's station wagon. Good luck. Pickups? Again, hard to find. I've had to make my own designs...
