I did a bit more wiring yesterday and today, and took some slightly less awful pictures. Only slightly, mind you...

Here are the two modules:

and here's the wiring. I spent an hour or so on Sunday making up the umbilical plug and socket (if this hobby offers any job more glorious than wiring multi-pin plugs I don't want to know about it) and mounting another tag board. I did a bit more in my lunch hour today (the benefits of working from home) and wired the umbilical to the tag board on the second module. I didn't recess this one since I might want to cut some of the board away above it and I'm not sure how much yet.

Part of the reason there's so much wire under there is that the accessory decoder I'm using has eight outputs, so rather than mount one on each board there's an umbilical cable carrying four sets of motor driver outputs plus the accessory bus. All the complexity of DCC and all the fun of analogue wiring in one project The decoder (an NCE Switch-8) is great though - cheap, screw terminals all round, and fairly compact.

Next task is to prepare the point motors (they're mounted horizontally so they need an extra lever and pivot) and get them fitted. Not a big job, but I need to find a specific piece of piano wire for the levers and I can't remember where I put it.
