The latter is as good as the former. Just do a search of the title with the added keywords "Williams" and "PDF".

That would be a good project to play around with! The one optoisolator he used may be difficult to locate, everything else should be easy to come by. Yes there is much over my head.
Our temperature is supposed to fall over night into the twenties, very windy today but sunny and clear.
Got some 100.000 mhz crystals on order, suppose to be different manufacturers so should be good for experimenting. Should hagve them middle of next week.
