WOW!
That is an amazing video.
The combination of living to 105 (almost 106+, by the sound of it, in August) AND knowing such accurate stuff about electronics, such as 555's, 386's, 741's, BC547's, etc etc. Is REALLY impressive, for such a long experienced person.
Almost 106, and he still climbs on his roof, and messes with Aerials on them!
So when he was born, even valves/tubes were in their infancy, and cars had not been around for that long.
He has an amazingly clear, recollection of electronics, at his age, wow!
I would LOVE to see the extended video, BUT ...
PROBLEM:
It seems to say "CLICK HERE for an extended video", towards the end of the video.
Time linked, here:
