@ Architect - Those are cool. The first round one looks like the beginnings of a Borg Cube
I wonder what his process is. Creates a multilayer schematic in Eagle (or other tool…) then uses that as a map? Can you imagine the debugging if you get to the end and it doesn’t work… That is indeed the ultimate geek clock, though.
@ Architect - Makes the Three Fives Discrete 555 Timer look simplistic by comparison.
@ devhammer - and weights as much.
He didn’t described the whole process, but some of it. It took hundreds of hours to make within 3 years period. I like how he used magnetic micro switches for adjusting the time on the clock.
