After the set back of finally constructing the board to hold the fiddle yard and the realization that I had used the wrong wood, enthusiasm sank somewhat. Undeterred I contacted the supplier or the wife as she is otherwise known to purchase some suitable wood and Aluminium strip well she does work there and gets a healthy discount. Thus was born MkII fiddle yard this time in the
right thickness of ply the plan I was to use Aluminium cassettes mounted on 34mm timber which will sit into the board, well I have only constructed one so far so perhaps that should be cassette . Major amounts of time was lost searching for the milled track joiner I knew I had, I did find lots of things but not that…….
So MkII joiner was made from some thin double-sided PCB Testing via a meter on Mega Ohms range showed a short only after filing away the entire middle of the board did the penny drop the resistance was caused by my sweaty paws bridging the rails.. There’s a moral there somewhere.

Finally today I finished and wired the little beauty and nothing, plug in one board it worked, plug in the other it worked join them together nothing on one board? A puzzle given I’m using 3.5mm sockets on a common bus, much testing and eventually the penny dropped the sockets I’m using are different pin outs a hasty unsolder / solder and test they both work. The bodged track joiner worked a treat given I had not even bolted the boards together and was relying on the C+L
joints only. Time to stop and drink a beer or quit while you’re ahead.
And Fiat Lux simple really a couple of cheap £6 ( a favourite word of mine from Homebase and as they say other retails are available ) clip on flexible halogen lamps solved my lighting problem well at least while I’m working on it not sure about public display if I ever get that far.

Serious track testing is now called for or is that playing trains?
