According to this article

1-clocks and 3-clocks are possible to make but they will "burn out" because of their speed, which makes them unstable. Redundancy can be used to maintain a 1-clock, even as the torches burn out; the result is the so-called "Rapid Pulsar"

Whenever I make a 1 clock, it pulses for a bit, then burns out and never comes back on. How do I implement Redundancy which will keep it pulsing?

I believe what you quoted explains why your problem occurs (instability due to speed) and the solution (redundancy). Perhaps you should elaborate. – Matthew Read Feb 28 '11 at 21:43
Yes, sorry. I meant to ask how to implement Redundancy to keep it pulsing. – Entity Feb 28 '11 at 21:46
Remember that even if you have a redundant clock, if it's unstable and you try to drive some additional circuitry with it, it will fail. – Nick T Mar 1 '11 at 17:16

A rapid pulsar works by basically having four 1-clocks, when one burns out another takes over. You can't have a 1-clock by itself without it burning out. The largest stable clock is a 5-clock.

But... how do you wire them all up so that another takes over when one burns out? – Entity Feb 28 '11 at 21:51
See designs A and F: – Matthew Read Feb 28 '11 at 22:10
I've built design A, but it always burns out... – Entity Feb 28 '11 at 22:43
The shadowed block means there should be a block above it. Each of those torches needs a block on top of it. – Kevin Yap Mar 1 '11 at 2:02

Using repeaters, which do not burn out, it is possible to make a one-clock:

Just inject a one-tick pulse from a pulse generator to set it going.
