This is a JDM like programmer. The JDM PIC programmer is well-known and very simple to build. However, since it uses serial ground as VDD, het power on the PIC is always-on during reading/programming. This might give problems when using the internal oscillator feature of the newer PIC chips.

Using a MOSFET to control the PIC VDD with the programming voltage, this problem is solved.
