[time-nuts] Frequency comb

2005-12-15 Thread Magnus Danielson
Hi! Those interested in time and frequency work should have a look at the Nobel Physics prize lectures. Especially the John Hall lecture was interesting. Yes, it's a brief walk thru the field, but could be an interesting guide to how we replaced the meter standard, what can happend in the future o

He's using almost 150 semiconductor diodes, isn't that sort of cheating ? He's also using fairly modern (TO-5 can size) trim-pots to tweak each stage. A true vintage unit would have used 3/8" hole, 1/4" shaft (or their metric equivalent) style pots, or else hand-tweak the resistors either

That is quite the nixie clock. A real labor of love. It's interesting to note that he used none of the tube-saving tricks that HP used in their nixie instruments. Another nixie clock builder in the USA did use these tricks and ended up with a smaller, but not as lovely, all-tube clock: http:/

Truly impressive-If I had one it would have to take out a shelf in wife's crystal/china cabinet! From a quick look (with no knowledge of German) I didn't see any overall power consumption figure. Maybe it's there and I missed it -can any German capable reader comment? Tnx Dave Brown, NZ
