Hello my name is***** do not rate until we are finished. I look forward to assisting and am very sorry to hear that you are having this problem.

To do this you would want to use a voltage doubler using two 10mF (10000uF) capacitors.

Put one cap to ground, and use a fixed resistor to charge it to 3v.

The second with 2 resistors, one to ground, one to 3v, using the largest resistors you can.
