Sorry, Lads!

In reply to your observations, Alex. Sat at home, I couldn't suss out what was happening. But then it occurred to me. The photocell is below the first light. When it cuts in, the first light illuminates the photocell. Need I say more? The lamps have a thermal switch inside them and won't re-strike u...

Re the original clock. It'll need a great deal of TLC to restore it! Perhaps we'll have a go at building an MSF(Rugby) receiver into it this time??

carriage lighting (or lack of it)

Have any of you lads got or know where we can get electrical schematic diagrams for the various coaches' lighting circuits. Showing the RCH plugs, batteries, regulators, dynamo, controls and so on. Any known websites? We used to have some in The Cubby Hole under the stairs but they've gone. The faul...

Solar Panels would have to have batteries. Both are expensive. If we used the very best lamps, they would perhaps be as low as 40Watts each and we'd need about 12 so that's 480W. That would need 24volts at 20amps. A big battery. If the lamps needed to be on for 3 hours and allowing for ageing of the...

In reply to the question about the slave clock. We could get a synchronous motor with a cam which trips a mcroswitch twice on each rev. In the past, I've tried this and the microswitch tends to fail 20,160 activations per week! Cheapest way I can think of at the moment is a little PIC costs about 98...
