Summary of Adapter for small size PIC/AVR chip programming
This article describes a DIY universal adapter for programming SOIC/QFN microchips used in RC micro airplanes. The author created this tool because standard connections were difficult, allowing for both chip removal and in-circuit programming. The project utilizes common household items like floppy disks and springs to accommodate various microcontroller sizes.
Parts used in the Universal Microchip Programming Adapter:
- Hot glue or epoxy
- 6 old floppy disks
- Plexiglass or piece of thick plastic
- Wire
- 8 pin chip socket or pins compatible with PIC programmer
- 6 springs (approx 2mm diameter, 2.5cm long)
- Drill or copper wire to make holes for the springs
This is a homemade adapter I made for programming SOIC/QFN size microchips that I use in my micro airplanes (http://maxoffsky.com/tech-blog/rc-micro-spitfire-airplane-build-log/).
I had trouble connecting the chips any other way so I made my own universal adapter.
This could also be used to do In-Circuit programming without removing the chip from the PCB.
If you want an adapter to connect and fit any size microcontroller, this Instructable is for you.
Tools and parts that you will need:
+ Hot glue or epoxy
+ 6 old floppy disks
+ plexiglass or piece of thick plastic
+ wire
+ 8 pin chip socket or just pins that you could plug into the PIC programmer
+ 6 springs (abt 2mm diameter, 2.5cm long)
+ drill or copper wire to make holes for the springs

-
Why did the author create this adapter?
The author had trouble connecting chips any other way when working on their micro airplanes. -
Can this adapter be used for in-circuit programming?
Yes, it can be used to do In-Circuit programming without removing the chip from the PCB. -
What types of microchips does this adapter support?
This adapter is designed for SOIC and QFN size microchips, including PIC and AVR chips. -
How many floppy disks are required for the project?
You will need 6 old floppy disks to build this adapter. -
What material is suggested for the base of the adapter?
The guide suggests using plexiglass or a piece of thick plastic. -
What are the dimensions of the springs needed?
You need 6 springs that are about 2mm in diameter and 2.5cm long. -
What is needed to secure the components together?
Hot glue or epoxy should be used to hold the parts together. -
How are holes made for the springs if not using a drill?
Copper wire can be used to make holes for the springs instead of a drill.
