I took out a solar power strip from my calculator, how do i use it for a mini fan?

"I took a strip of solar energy in my calculator, how do I use for a mini fan? "Its just the strip only, just hit the wire on it and I cover my HOMEMADE fan?

    The solar strip should have two wires. But it is really small and only designed to generate the power needed by a calculator (which is almost nothing.)

    So, your home made fan should be a very small and low voltage DC permanent magnet motor. But I think you will find that it is undersized to drive even a small motor, much less with a fan load.

    You can characterize the solar cell by connecting a volt meter across the cell and reading the open circuit voltage. Then measure the current using the same connections to the solar cell. This will provide open circuit voltage and short circuit current.

    Now, your motor has to be rated for the same voltage and require less current than the cell can provide.

    Good luck.

    you will have to use a large # of them in sequence then common to normaly white pos.black may operate either way may change direction of fan either way hooked up many needed solar panels cheap at harbor freight POSITIVE NEGATIVE POLES 1 EACH
    COMMON & POSITIVE
