How does the back unbolt to access the bulbs if they need replaced ?
Wait…it’s hinged ?

On the dwarf signal, there’s a big center nut that you unscrew, and then the whole back comes off. Being cast iron, it’s &#$&# heavy and awkward.
Wow, way to go, BD!!
Looking forward to seeing them installed!
Nicely done, Bob. I am enjoying your 3D printing adventures (https://www.largescalecentral.com/externals/tinymce/plugins/emoticons/img/smiley-laughing.gif)
Swell. Something else to worry about besides EOT bricks…(https://www.largescalecentral.com/externals/tinymce/plugins/emoticons/img/smiley-wink.gif)

From the pics I’ve seen you don’t worry about them at all (https://www.largescalecentral.com/externals/tinymce/plugins/emoticons/img/smiley-cool.gif)
A bit more progress. Over the fall I worked on the layout of the WiFi remote node boards. Yesterday I got some quotes, and ended up shipping the files off to PCBWay for fabrication. $5 for 10 boards, plus DHL 3-day shipping for $24, from China. They were in production within two hours, and right now are being QA’d and will be shipped probably later today. The same board, from OSHPark (US manufacture) was going to be $63 for 3 boards, plus shipping, and 7-10 days.
Nice!
What software are you using to draw the circuit paths with, and what file formats does the board printer need? Thanks.
I’m using Eagle, which will export out Gerber files, which everybody uses. The auto routing isn’t too bad, and you can just tweak the routes if you want to.

That don’t like it will fit in the back !
Boards came and I had the chance to evaluate them. Quality is top notch, as always. I have no complaints. One error on my part on pin spacing of the four input tabs (top center), but I can work around that. Placed some components where they will live.
How big is that, and do you need something to house it in out on the RR? I’ve got about 6 1 foot pieces of 4x4 PVC fence post painted black about to go in the dumpster. Also have a few 3.5x3.5 x about 4 in mill finish aluminum extrusion that I’ll probably never use. I’m going to use a few to house the servo and LEDs for my turnout project.
About 3" square. I have an eight foot chunk of PVC post cover that I’ve been making equipment houses out of. These will fit nicely in them.
Some more progress. Got a remote node built and running. Have had the base node working for a while, and I have it connected to JMRI. I wired some jumpers to the Proceed and Stop aspect of the first signal and started pressing buttons in JMRI. It’s alive! I tested all 12 outputs and they work, so the board design is correct.
That looks pretty neat Bob!
Hope you having a great time with this - sure looks like an interesting project.
Sure do hope we get to do TrainOps this year!
Yea, its fun when things just work.
Quick followup, the 4 inputs from the board report back to JRMI, too. So the manufacturing design of the node is correct. I have to tweak a few pad placements, and make the board a tad smaller, but time to start building them out!

Sounds good…I think. What’s the end plan?
