The circuit board of this clock is rather a work of art. Impressive. I recall an old professor of mine built something similar using two hard dive platters as the base. He skipped the seconds ring though, so his only had the two rings. Never saw the circuitry behind his clock, but I doubt it was a nice as this example.
- rohern 15y agoIt is very beautiful.
- DanBC 15y agoThe PCB is beautiful. Remembering that it was designed by hand - someone had a sheet of acetate and Letraset(tm) pads and crepe tape. I'd be really interested to see how a modern auto-router would cope with the rat's nest files.
- Arjuna 15y agoRegarding the circuit board, I find it intellectually satisfying to see that he placed the date that he made the clock onto it (8/8/1970). How many times have you opened something up and asked, "I wonder when this was made?"
- fanf2 15y agoMany chips will have the manufacturing date on the package in the format YYWW: two digit year and week within the year.
- Wistar 15y agoThe beauty is on the inside. Although the wood case is handsome, I think this would be very nice in a case that allows a view of that amazing looking circuit board.
