      Bob;  Lawrence Watkins started trying to fabricate simple signals, using electric conduit  parts.  Although not to scale, and on the large size, they don't look too bad. He had a problem getting LED's bright enough to be seen in bright daylight, and sort of gave up.

      Along came Steve Watson and his wife Seana, taking over as leads on the project, and trying to use automotive LED's.  They are available in Red, Green, and amber.  They have made two test samples, which work great, can be easily seen by the operators, are very inexpensive, and should be very weather proof, along with being very durable.

       We are going for simple two headed signals, with red and green heads.  I hope someone will take pictures soon so I can show you.

      The cables to activate the signals are now in place, and the small power supplies are on hand.

      A three headed signal could easily be built, if we need it.

      As I have mention on many occasions; these signals are not to just "Look pretty". They are to actually be used for part of the operation, as a dispatcher controlled fixture.

      Fred, please keep us posted. I want some cheep signals for my railroad. The wires for them were put in place when I built the railroad, but as of yet they are unused.

      As soon as I get the pictures that were taken of the test samples; I will get them posted here....and I'll try to describe the simple wiring involved for our needs. No PC boards or high tech stuff. Basicly controlled by a dpdt switch......using automotive LED's, and a 12 volt power supply.

         This system I'm using, is in no way meant to offend Bob McCown, or what he is planning, and I really should move my project to another thread of its own.......

         Bob offered to help me with signals, originally, but due to his other responsibilities, and troubles with his design; I've been working with several people here to get the project here, through to operation.  I still would like to get a copy of his panel switch (Or two) here for the dispatchers board....!!!

      Fred, I have 2 double pole throws of a relay just waiting to be wired up. They can control LEDs by reversing the polarity on the wire pair. So lighting and controlling them isn't my issue, my issue was the cost of what was available and that it simply didn't look like what I wanted.

      Some minor progress on the signalling last night.  At York, I talked to Dave Bodnar and he pointed me at the HC-12 serial radio board.  Its a neat ~$5 board that supports high-speed/long distance serial communications.  Bonus is that it has minimal configuration.  They look easier to use than the XBee modules I was playing around with.  I bought a handful of them and am waiting for them to arrive.  

       

      Last night I dug out my Railstars io:Duino board, and finished up the LCC node code so it looks like a 96-pin output board to JMRI (If you want the sketch, let me know).  Since I'll only need 80 'remote' output pins, grouped by 10s, this will work nicely.  Once the HC-12 boards show up, I'll add the transmit code to this sketch, and start on the remote sketch for the Arduino Micro Pros that I intend to use remotely.  At each interlocking, the hardware will end up in one of my equipment sheds.

       

      Baby steps!

      Last night's progress.  I have the HC-12 boards talking to each other.  Here's a picture of the io:Duino board with a development shield attached, with the HC-12 board mounted on it. 

       

       

      And here's a shot of the debug console for the receiving node.

       

       

      Next up, protocol work and getting some LEDs wired up.

      My knowledge and desire to learn on this type of stuff is limited, BUT I do like to kinda stay informed of where trends in the hobby are going.

      When I click on a thread that is "foggy" to me (more and more of these all the time), I click on the page before the last update and read all the previous posts to get me up to speed.  The start/top of page 6 was in 2014.  Baby steps are mentioned, Wow! 2014 to 2017 on one page.  Kind of a new definition of "Baby Steps", but it also shows perseverance.  Should prove interesting to operate on, when complete.

      Ric, and others;

        The signals on the IPP&W are completed, at least at the junction of the RP&M, where they protect the crossing of the IPP&W. There has been a further installation, over on the line from Mount St.Helens to Craigleigh. This later application, protects the entrance to Craigleigh, and is controlled/activated by the Craigleigh yard master. I will attempt to get some pictures posted to this thread in the near future.

      Some more progress.  I downloaded the latest JMRI, and that has a bunch of additions for OpenLCB nodes.  I did a bunch of debugging on the ioDuino, getting it to work exactly right.  So I now have a relatively fully-compliant OpenLCB node receiving, and transmitting out to remote nodes built on an Arduino Pro Micro.  I've uploaded a few videos
