      GAP - In your blog post you mention that some of the testers worked differently. Did they all come in the same order from the same source?

      Yes they did;  the only way to physically tell the difference was by the colour of the circuit board, the other way was at power up with a servo connected it moved the servo to the travel extremities before settling at the point where the control knob set the position.

    • I have published a page on my blog which shows the whole install of the servo controlled points, it contains links to the original article and the components used.

    • Looking good!  My project has stalled in the breadboard stage.  Weather got better and my attention turned to finishing repairs on my RV so we can go camping soon.  I did order a RailPro AM-1 accessory module from Don Sweet that will be here early next month.  I'll keep the breadboard setup while I work out the interface.

       

      I do like your linkage ideas. Much better that trying the bend brass to exactly the right length! I bought a bunch of clevises and other push rod parts when my local Hobbytown closed up, so I should have everything in-stock to follow your lead.

    • I installed one servo tester, wired it up to the 5V the bus and mounted a switch to the control panel.
      Next I installed a servo next to a point and connected it to the tester.
      Following that I connected the servo horn to the point throwbar via a control rod with a clevis pin at one end, on the other end of the control rod at the horn I put a "Linkage Stopper" (these are used by the model aircraft people quite extensively).
      The stopper has a grub screw adjustment so when I set the servo travel extremities using the 2 pots I could make fine adjustments to relieve any residual tension being applied to the control rod.
      As the point I started with was on a crossover, I attached another servo to the other point and connected it to one of the tester outputs (there are 3) and now both points change at the same time controlled from the one control panel switch.
      Now that I have it all working I will proceed with installing the rest of the servos to my points (12 of them).

      The servos I am using are waterproof and are mounted under the baseboard.
      I ran my irrigation sprays that are under the baseboard and no sign of any part being wet.
      We also had 4 days of heavy rain and no water got under the baseboard everything was dry.
      I am going to put a smear of silicone grease around the servo shaft to increase water repellence around its entry point.

      I am using double walled heatshrink with a glue inside to keep moisture out of wiring joints.

      That's NOT a brick!!!     (Try building a brick house from "bricks" that size...

       

      (Edit:  A standard brick is 3 5/8" x 2 1/4" x 8" and weighs 4.5 pounds)  I don't think Jon could have run through THAT!

           

       

      I didn't' run through anything.  I was the conductor.  I believe the engineer blamed it on that low-tech R/C in the gondola

       

      And here I thought it was blamed on the low-tech conductor!    (Sheesh, try to defend somebody for running his locomotive past a "brick"...)

      Hopefully you have a brick at the end cause that will stop a 45 toner !

      No it won't.................

      I don't remember a brick...

      Guys;

         Although I really appreciate a working signal system, and the work involved in building one for a true OPERATING model railroad; I have learned over a few years...that there is a fine line between an OPERATING railroad that attracts operators, with FUN, and one that tries to be too prototypical...PLEASE be aware of that line...

       

      Or I can run signals on my railroad.

      There's also a lot of work involved with a dispatcher.  And some people ignore that as well.

       

      As long as you're having fun, does it really matter?
