********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
