PRR position light signal

After some time spending on the “best-practice” for assembling the multi-parts head on the PL I came around with a good alteration of the prototype. Photo below shows the last testrun. Tiny SMD 0402 inserted into the lamp holes, and the head glued to the crossarm section.

I also managed to get some more detail parts done, the 3D printed bae and some photo etched ladders and plattforms.

And last but not least, I manged to get the firmware running on the chip and with a littel help I manged to design a circuit board which will incorporate the mast socket and 6 input ports arcording to match the output on a SE8C from Digitrax Inc.
