We gotta make a plaque for our class gift. I was thinking about making a clock that runs backwards...anyone got the know how?

I would imagine that you make the face and then go to a craft store and buy the clock internals, and open them up and reverse some wires (I'm not sure so i'll say the biggest wires you can find).

That is just my guess at how it would be done.

well you can just buy the motor assembly at most craft/hobby places...the ones that run on aa batteries. then you could pick any surface or shape and put the numbers on it.....as for running backwards though i am not to sure.

I belive you would need to reverse the motor if possable

regular clock and then use two identical gears to get a backwards running clock.

I would buy a clock mechanism. I bet there are even ones that run backwards...

I think you can just switch the two wires on the motor.

If you're making a clock, this is what you want:

(someone who has actually made a clock is your friend)

Just make a pendulum about 1 meter long. It will run forwards, backwards, forwards, backwards, forwards. Each 1/2 cycle coincidentally will be approximately 1 second. Makes a pretty good stop watch if you can count
