    • Pretty cool how that works Bob.

      Another minor update. I have all the electronic hardware for the CTC panel installed and wired (three boards, 50-ish LEDs, etc), and now I've started the JMRI scripting to make the panel actually work.   Here's a short video of the first control point leaving Burke yard.

      Some more progress.  Ive been working on the protocol for talking to/from the remote nodes.  I build up a second remote node last night to see if I was getting any data collisions or dropped packets anywhere.  Looks like the answer is 'no'.  So working as desired.

      Not a lot of progress on the mesh network, but I did get the remote node built up on an Arduino development board.  All components I got from Aliexpress.  Total remote node cost is somewhere around $6.   The design allows for up to 12 digital input/output pins, 4 input (via the analog input pins) or some combination thereof.  Dropping this shield on a Mega, or combining it with a Mux Shield would get you even more pins.

      Been slow the last week or so, just doing some wiring on various things.  Here's a short video I shot this morning on the occupancy LEDs on the CTC panel.  Minor progress.



      You can also look at my other videos in my channel to see where I am.

    • A bit of progress.  This is an inside view of the Burke yard office.  Servo on the upper left. Yellow and green paired wires go to the semaphore light, and the light over the door.  Power comes in the two-place terminal strip at the bottom, gets turned into 5v by the board next to it.  The white board center-left is a Nucleo F091RC STM32 board that takes care of the logic.

    • Nice !

      A quick and dirty project for a train order semaphore at Burke.

    • Closest diagram/parts list is the 2070/2171 pdf.  It is a 3 wire motor block and will need one motor lead isolated from the track.

      Hopefully it is not the split case as the wheel brushes and springs will fly away when the wheels are removed to get at the access screws to split the block.

    • Yea, "DCC ready" means that the locomotive was built so that a decoder can be plugged into a plug inside the locomotive. The plug will have a jumper board plugged into it, so the locomotive will run on DC. So, technically you want to make the locomotive DCC able, not really DCC ready.

    • I can't find the manual, but it may be out there.

      I'd guess it is a 3 wire block, which needs a wire soldered inside the motor block and a small insulator added.

      Then you have 2 track pickups and 2 motor leads.

      Can put almost any decoder in there, but it is NOT what you would call "DCC ready".

    • A friend has a LGB Zillertallbahn 2071D (purchased in Germany approx 1991.)  He is interested in making this loco DCC-Ready.  I am not familiar with this loco.  Is this something that can be fairly easily converted to DCC-Ready so it can be used with a decoder?  Is there any motor isolation required? or anything that makes the job more challenging than normal?

    • Forrest, the debt consolidation place told me, way back when, that my only option was to sell my truck and go on welfare. By the time I got home from there, I was past being hurt, and just so darn mad, that I started calling back all of the places I had interviewed with just to make sure that they really didn't want to hire me. They had said no, but did they really mean no? One of them had hired a guy that didn't work out, so they gave me a try. 24 years later and I am still repairing copiers, never once was on welfare, and eventually traded in that truck on a Jeep, after I put another 140,000 plus miles on it.

      Sounds like ya need to cut back on expenses Later RJD

      Brings to mind a budget math exercise which showed I could live pretty comfortably on Social Security disability if I got rid of the car, the phone, and the electricity.

      And, no, that's not a joke.

    • I used to carry nail polish in my tool bag. It was a common repair item back in the days of analog copiers.

    • Oh, I thought maybe for dress up days or if you have nieces...

      that awkward stage eh?

    • Toe nail polish? Why would I have that? I do have some grain of wheat bulbs. I'll ebay some 2mm LEDs next week when the account is barely above zero again.

    • I figured you'd just paint a couple with toe nail polish. If it was good enuf for grain of wheats.... then.

    • Designed it for 3mm 'cause I thought I had some. Since I don't, I decided it would look better with 2mm LEDS anyhow.
