Also made some round pole barriers today, the ones that go around holes in the road. I have no idea if they are realistic (1950's) but to me they look appropriate (rule no.1). viewtopic.php?f=22&t=44849&p=638877#p638877
Now the buildings are back on the layout, although the 32 way switch box is ready to go viewtopic.php?f=7&t=49960, I have been making splitter boards to distribute the power to all the lights on the layout.
The 50 way D-Sub connects via two 20 way ribbon cables to a 'main' PCB. This splits the 32 channels into four 10 way header connectors. Each header feeds a 10 way ribbon cable. The ribbon cables have IDC connectors that can be placed anywhere along their length. Each connector plugs into a 'sub' PCB, that splits off into four sets of three pins. Each of the three pin connects accepts a servo cable. The servo cable carries two switched circuits to the building. Each building has a lead hanging out of the bottom that pokes through a hole in the layout, to connect to a servo lead. The middle two wires of the ribbon are the common, so eight wires are switched, any one can be picked up at any point along the ribbon. A diagram will be forth coming with appropriate accompanying pictures.
