@kimvellore This is above my head. For me it will have to wait untill it becomes available commerialy. I recall that there is an article in MR about doing this but it would completely analog. I may have to track that down. Thank you for the response.

@drupp68, I built a circuit to generate the square waves to drive the coil directly. The chip generates 1S pulse so did not mess with it.

@kimvellore Did you hook the clock up directly to th chip or did you buid an entire circuit? Sorry for th basic question here. I know very little about this sort of thing.

@kimvellore That sucks when things tend to seem easy, but have such 'disadvantages'

I probably would have sovled the problem by using a tiny H-bridge.

That is how I started with pulsing the coil but it did not work for me on the clocks I tried. The pulses had to be positive and negative, in other words you have to switch polarity, I used a microchip and used two outputs which alternated between 0 and 1 switching polarity.

The 'normal' way of converting a clock to a fast one, is to disconnect the wires to the coil that, in normal operation, gets a pulse at each second: controlled by a tiny oscillator, with the crystal as main component. Desolder the wires from the coil to the normal circuitry, and hook the coil to a pulse generator (with a 555 timer IC for example) and you're probably done: haven't done this myself... but that seems the only explanation to me....

OK, how does one go about converting a normal clock to a fast clock?
