    Yes to 1

    The 2.7k forms a voltage divider. If it's too high VPP will be calculated incorrectly.

    2.7 k

    if its a voltage divider .. then what is the complement of the 2.7 k ... is it 4.7K (i guess)?
    if its so can i design another voltage divider using 3.3k .. then its complement has to be 5.7k (if my calc is right ..) .... will it b ok ??

    That should work. As long as the total is less than 10K and the ratios are the same.

    Really I used 3.3K their in earlier versions. Now I've have the 2.2K baby.
    Nothing was wrong in both.
    But my suggestion is to make the full PICKit2 or Bill's magicboard:) Junebug.
    If you buy a Junebug, you're ready for big leagues. But....
    If you want a PCB layput, I can give you my own, which I'm using for 3months approx. It is easy simple singlr layer and pretty much home-makable.

    i use a pickit2 lite with mplab ... when i attempt to connect the pickit2, the os is recognised but i get an error message stating that the Vdd is 2.29 Volts which is out of the range (3 to 5.5 volts) ....

    what might be the problem ???.. i use a 650 uH inductor ..
