A compilation of clocks, would that be interesting?
At Elektor, we have often thought of publishing a compilation of all our innumerable electronic clock circuits. But I think such a publication has never seen the light of day. And if I am wrong, it would be because its short-lived success can’t have made much impression. I do remember very well some epic discussions during which the proposed compilation project was invariably shot down. “Our readers love clock circuits, of course. But to go from there to a compilation: NO!”However few subjects have generated as many rejections as electronic clocks. Every Elektor reader has been has been struck at least once by a memorable electronic clock circuit. So I’m taking this opportunity to ask you, our readers: “Would a compilation of clock circuits published by Elektor be of interest to you?”
Please respond in the comments below.

By lighting the 60 (of course!) RGB LEDs, and forming luminous patterns, we quickly learn to read them like the positions of real hands.
I can imagine this clock being a great thing to have in a waiting room, because while looking at it you don’t really sense the time going by.
