    If you like a simple challenge, perhaps you could suggest components to construct a timed polarity changer that can run on 4.5v and be very economical on power consumption.

    Three D-cells in series with two DC outputs (one +, one -), after 3 minutes the polarity would switch, after 3 more minutes the polarity would switch back, infinitetly...

    perhaps a micro relay could be used?

    circuit current will be non-existant, only importance is the potential
    thanks for any help :D

    Is this an assignment for school?

    You'll probably think I'm crazy, but here goes...

    There is a device invented by Lee Crock which originally used 3v, but it has since been proven that 4.5v works better. I was hoping that someone could help in creating the switching mechanism so that I (and others) could build our own...

    Google for "Lee Crock" or "Aura Cleanser" for info about the device...

    Thank you for any suggestions!:):):)

    I have attached a very rough overall of the circuit.
    It will be powered by NINE "D" batteries
