Many are interested in collecting different homemade on PIC controllers. For example, like: Toddler FM2 or other. But PIC-requires flashing an individual program into it, and programmers are becoming more expensive every day. Below is a diagram for self-assembly of a USB programmer PicKit2 lite do it yourself.
It is not large in size, but it will please any novice electronics engineer with functions.
Details are all easily accessible. The heart of this programmer is the PIC18F2550 - this is the only chip that will need to be flashed.
If you are a beginner and the firmware of this microcontroller is new to you, the easiest option is to ask someone or there are always guys at the nearest radio market who will not flash it for you expensively. But then with such a programmer, all roads are open before you.
I could not get some details according to the scheme, namely:
kt3102 - replaced by BC547
Drosel 680mkGn - replaced by 560mkGn
When checking everything worked the first time, the trial firmware PIC16F628 was successful.
Scheme of connecting microcontrollers to the programmer
Used the program PICkit2V2
The board should be opened in Layout 6
