Hrar. Open day at School today, and in the lead up I have also been really busy doing a lot of reports to the Governors. Open day is a good day because I have to be there, but after the place is looking Bristol-fashion there are few demands on my time so I've finally brought the desk from weeks of paper down to woodwork.
Anyway, when I got back TSC, TLHC and her cousin were off at a birthday party so after a short time in the garden with a paper and a beer I got to my HST & the directional lighting. The Black Cat kit suggests that the PCB can just be slotted in in the front of the cab and the existing contacts will make it work. Sadly this isn't the case, so it was out with the soldering iron:
Eventually I got to this:
And with the power the other way this:
It then took a lot of messing about to get the power & new lights into the powered power car, and synchronise with the dummy. Whatever I did, the lights were the same at each end depending on how I turned the dial - right, all white, left all red. Then there were no lights at all.
Eventually TSC, who had come home, looked at my test track and said, "Daddy, you know how you have to make a circuit?" "Yes, I do." "Well, Daddy it's not working, the power needs to go all around." "Yes, TSC, I know." "Well Daddy, the bit of metal you're using to stop the engine moving is going in front of the engine and making the electricity go away..."
Good blooming point. Here's what I have now:
Well done his CDT master, I say!
