Thanks Fred. It's been interesting, if nothing else.

Jim, I was complimenting the photo of #173 demonstrating that its headlight had power

That's what I figured after Karl let me know the Dropbox URL was incorrect. 173 is probably 'thee best' running loco I own. Maybe a scale Million Miler.

Jim, I watch your work in amazement even though I have no clue what you are writing about.

Jim, Do a search on Youtube for Arduino turntable. It can be done.

Dave, that makes two of us.

I hopped over to:

BURLEY JIM - HARDWARE and ELECTRONICS

Pre-Grand Opening, and looked at some of the stuff you let me drag over.

Packed away was this Stepper motor from another old stalled idea.



Oops! Not Inventoried in the database.

It looked like a possible candidate, I tested it quickly with my Arduino UNO, (another rabbit hole!) it worked. So I drew up a mounting plate for it, and started it up on the printer a little before supper. I retrieved it around 9pm and after a boring episode of 'Oak Island' and checked out the fit.





I drew the countersunk holes for the 3mm Socket head cap screws to mount flush with the bottom of the plate. It will be flipped over and mounted in place of the servo, and tested there. I'll build the adapter to the turntable tomorrow. I've got 7 minutes before I turn into a pumpkin.

Thanks Bob, when do you start building one, or have you started already?

I'm just gathering information at this point. While I've considered adding a motor and indexing system I think I'll be happy using a hand crank to operate the turntable but I'm looking for ways to have operating doors on the roundhouse. I have been following along here and found your method instructive but I want to detail the interior So I would rather have the servos and linkage below deck. I provided the suggestion in an effort to help you continue to make progress.

Thanks again Bob, The problem I saw was coming up with a way to pivot the doors in unison with one servo at the bottom. The track and engine kept getting in the way. I had enough room 'above' to pull it off, so that's the route I took. I'll be very interested in how you do yours.

Jim,
It's nice to have your own hardware and electronics business.

That stepper looks like it'll do the trick. It'll be interesting to see it all put together and operating.

I hope so Bruce.

Dave, You're the the guy who built it!

It's getting close Bernd, The stepper is definitely a better method than the Servo which is just too sloppy to control. This stepper is a 400 steps/rev unit which enable .9 degree resolution. 11 steps will allow me 9.9 degrees between stops at the roundhouse tracks. Close enough for Gov'mt work.

Wow Jim,
My head is spinning round and round with all these developments, oh wait it's the turntable.
I love all the mish mash of found stuff, and printed stuff, jigs, and testing.
Good thing I have a beer next to me.
