How to make a JDM Programmer

JDM programmer is a serial Microcontroller programmer. It is used for loading the compiled source code( .hex) into the microcontroller with a DB-9 port. Its quiet easy to make. we are going to make this board for loading the code into microcontroller board pic18f4550. JDM programmer does not have a capability to program through a USB port but its quiet a cheap and easy to make at home if you don’t want to invest on costly programmer like pickit2. Its one of the easy legacy model for programming microcontroller. You can find the necessary schematic and description here to make this programmer at home with in an Hour.
