My wife has stopped Zooming, so I have got the lap top back. I missed yesterday afternoon as I was teaching myself to solder Surface Mounted Devices (SMD). These are very small, a 1206 resistor is 3.2mm x 1.6mm (or 1/8 x 1/16 in real money) so head magnifier, steady hand and a new pair of stainless steel (non magnetic) tweezers. For inanimate objects they are very mobile and ping out of the tweezers never to be seen again! I also tried a technique using a (very) hot air gun, but that took the trip out after 7 resistors...
Meanwhile, where is this level crossing? Its quite pleasant beyond it these days, but it was a different story in the 70s and 80s.
