Hi all I need some help with an ATmega168 programmer board this is the diagram I’ve put together.

This is the website and the source of the original diagram

the thing is can this be reworked to use the 5volt of the rs232 instead of the added 5 volt regular I have added if so can you please post how to modify it.
This is my board layout but not built yet.
So all I’m trying to do is use the 5 volt from the RS232 port to power the ATmega168 without having an external PSU. Thanks for any help.
