    Ni-xx batteries can be safely charged even with 0.5C without any damage. BUT, not continuously. You have to "fiddle" a little bit with chemistry (ions buildup on electrodes during charging) and to...

    Closed: Re: Stepper Motor max speed

    You should mention that 3334 is 57STH56 NEMA-23 Bipolar Stepper with 77:1 Gearbox
    From reduction ratio you can calculate the max speed of STEPPER MOTOR. I won't do that trivial math for you.

    Closed: Re: IR2103 or IR2110 which one is better

    Download datasheets from for both chips and do a comparison by yourself.
    That way you will be able to decide which one suits your application.

    I've seen 3 phase kWh meters with PIC16F870 with no specialized front-end IC.
    I'ts up to you to decide which uC you will use. The one that you are most familiar with would be my choice.

    You are absolutely right about "tester" :D
    If he does not survive, anyway will be "grounded" :D
