AVR ISP Programmer


Description

This is my DIY AVR ISP programmer. It is a parallel port programming dongle, compatible with the stk200 design. It is based on the 74HC244 buffer IC and I have used it successfully with PonyProg in Windows and avrdude in Linux.

If you intend to build the same type of programmer, make sure you read first this thread on the avrfeaks forum; it will help you avoid some problems.

A view under the hood. I recycled a plastic container from a lighter and spray-painted it blue.

I have added the two optional LEDs; one to indicate power and one for programming.
