Summer 2024 layout update

We are already almost half way through 2024 and June 20th marked the first day of summer this year so here's a summer layout update.

I have been working on finishing the occupancy indicators for the east end staging and return loop.  Going to be using the last 2 of the 8 channels of the Azatrax MRD8 unit that I never thought I would fill.  With a total of 32 input wires and the small spring type connectors used on the board, I have found it difficult to get a reliable connection for the last few inputs especially when more than 1 wire has to connect to a terminal.  So I have installed a 25 screw terminal strip to make it easier.

I needed some more Azatrax IR sensor pairs for that project and when ordering them I noticed the Azatrax also has a dual track occupancy detectors so I ordered that as well as I am also going to be adding signaling to the upper helix.  I noticed that these have a sensitivity adjustment on the board and am looking forward to seeing how that works.  I'll post more detail on both of these projects as they develop.

And I have been working on finishing another 3D printed house for Carlin.  All three of the houses got a primer coat at the same time last year. This one, the 2nd one recemt;u got a base coat of white and I am now working on hand painting the details.
