Do you think the C/C++ world/message board/audience/programmers would be interesed in purchasing pre-made kits for programming ports? I keep seeing people on here posting messages about programming the parallel port or serial ports. If I made kits with printed circuit board, the necessary electronic components, a short visual manual, and source code and sold them as cheap as $9.95, do you think anyone out there would be interested? Or is it a waste of my tim e?
