Or something like that.
Any heads up for what i have to look into?

Your best best may be to replace the clock controller chip with a microcontroller which you can custom program (Arduino? PIC? AVR? Something else?). Or, you could switch in a new time base in place of the 32,768 Hz Quartz crystal (Almost all electronic clocks use a 32,768 Hz Quartz crystal as a time base, since that, when divided by 2**15, produces a 1 Hz/1 second signal.).

I'm told that certain older clocks could be spoofed by strong RF fields (much to the chagrin of various RF engineers).

Removed the crystall and such and hooked the battery right up to the motor so it goes non stop.
I am now trying to usa a 555 timer to make the motor go random.

I did se the very nive arduino controlled clock but i am hoping to do it with simpler means.

Any help how i wire the 555 timer to make the engine go random would be realy nice.
