    ********first’1′-************–

    u canot find a 5 volt battery

    insted u can use a 7805 regulator ic and

    9v battery as input

    it will give you 5volt suppluy

     

    *******second*********

    u will never find axact 750K resistor

    so you can use “preset”(small potentiometer)

    or

    use 680K and 68K resistors in series.

     

    i prefer you to study the the book

    “practical  electronics for inventors”

    you can find it free pdf online
