      I'm using the Mars light feature of the Drop-in with a single 5mm LED. FWIW: S.P. used both the Mars and Gyralite offerings for headlights and as emergency warning signals in RED! Espee didn't run ditch lights with the F units. As I recall other than different vendors the Mars worked in a vertical figure eight and the Gyralite did a horizontal figure eight.

       

      I might have a W.P. 'B' unit, I know I have two 'A' units NIB for sure. I'll let you know. We have a local modeler with a Zephyr train, Joel bashed the OBS car with a Vista Domes, dome.

       

      Noels railroad is great, lots of unique features. I'm sure your welcome to visit the Sante Fe & Butthead R.R., Noel is a great host....

    • Hi Michael -

       

      Nice video! I have family that lives right around the corner from Noel in Rio Linda. Next time I'm up that way, I need to stop by and see the Santa Fe and Butthead Cove Railroad. That SP Overnighter train looks and sounds real nice! And to top it all off is that cool Mars light (or is it a Gyralight?) on the front of your F3A unit. I need to seriously consider adding one of those when I do the battery convert on my WP Zephyr combo. And I think ditch lights too.

       

      Dave Bodnar went all balls out with his Mars light right here. I'd love to have one of these:

      Not sure if this would fit a G scale F unit:

    •    It looks so real. I love the weathering on some of the cars, and I like the new-looking ones too. I must criticize one aspect though....the kid at 5:50 is way out of scale.

       

         edit: the caboose (no caboose, no train, I say) makes up for the kid!

    • The attached video is of the maiden run of my Southern Pacific Overnighter consist on Noel Wilsons layout in 2012. Later I eliminated the second B unit and replaced with another A unit as was prototypical of the Zipper as it ran between Southern California and Northern California. As noted previously each engine has sound.

    • Epoxy like JB Weld will hold much better if the surfaces being glued are roughened first with sand paper.  Sheet metal or plastics are usually very smooth leaving little "tooth" for the epoxy to grab.  Thermal expansion can easily flake the epoxy free from smooth surfaces. 

      UV should have little effect on JB Weld beyond its surface finish because it has opaque fillers which would stop the UV rays from penetrating.  Clear epoxies like i use on my wooden boats will break down due to UV without a UV resistant coating.

      So did I miss understand from a few pages back that the JB weld on the targets doesn't hold over a summer or two? Looks like a cool project, one more to add to my list, as soon as someone can interpet all the foriegn language and computer stuff. Maybe for simple minds like mine , just wire them up to work and show a color will be enough. Thanks Bob

       

      No, I've had a test signal mast outside for about a year and so far no problems....

    • That's odd. I made a switch frog out of JB Quick, the quick setting version of JB Weld. But then my switch is in shade and partial sun.

    • Was the use of JB Weld outside?  JB Weld is an epoxy and may be subject to UV breakdown.  Simple latex paint will give protection.

    • Zip ties holding the super conductor to the parallel unubtainum that are receiving the coaxial coherent's with banana plugs are certainly not OSHA approved ?

    • Wow, just went back and read the previous posts.   Sure, it's been a long road, but reading it all in one fell swoop makes the journey seem a LOT shorter.   You NEED to get these out on your layout, then write an article for Garden Railways.    Too cool!

    • Isn't it hard to do interlocking with only one signal? 

      Looks good, but I want more than one - and OUTSIDE!

    • May 12, 2018 5:11 PM EDT
    • Built one interlocking signal (mostly).  Still need a finial, and the wiring plugs.  Only 10 more of this style to go.

    • Crap, disregard my comment about H bridges. I thought it was a encoder at first glance, not a decoder.  

       

      The NmraDcc library (available through the Arduino Library Manager) is pretty robust for both stationary and motion decoders. Not super intuitive, though. This is what I’ve been using for my AirWire decoder experiments.

      Yea.  I'm *just* getting into DCC here, even though Ive played with Arduinos (Arduinii?) for years.  Not even sure what I'd use it for.  I'd probably piggyback an optical relay shield with it and use it to turn lights on and off on the RR... 

    • May 11, 2018 11:50 AM EDT
    • Note that the DCC shield only provides 400 mA.  If you want to do this with G scale, you could use a higher-power H bridge, and toggle the direction line with the DCC bitstream.  An intermediate option is the 2A Motor Shield.  The DCC++ project has info on using this to drive both main and programming tracks.

    • I can understand how some people prefer tactile controls, But I am so happy with JMRI free software connected to my DCC system (Digitrax) and android apps as wireless throttles on my old smart phones and tablets. Friends and visitors have downloaded the app on their android or iPhones and can run a train intuitively. All function buttons available and labeled in plain English on the throttle app.

    • There's also this one, but it's in the UK

      I'm hoping their Proto Throttle comes down to a more reasonable price, it really looks like fun.

       

      Yea.  500 clams for just the throttle is a bit steep, even if it is cool.  Someone needs to come up with a beltpack implementation, too.
