Hi, I am at the middle of my new project with Arduino and stopped with the problem of soldering some connectors: this: http://www.sparkfun.com/commerce/product_info.php?products_id=570
I first searched to find a PCB ready for that in local markets(even with more quantity of pins) and failed.
Next I bought a marker with 0.1mm tip and challenged for some days to design "own" PCB and again failed.
The last idea I have is to use this cable: http://parts.digikey.com/1/parts/35470-cable-flat-flex-5pos-0-5mm-5-050r05-127b.html
and solder it from one side to the connector, cut it from the other side and freely use wires (must be easier to solder them). This way to use the ribbon cable as a converter.
I would like to know the opinion of gurus here if it has a chance to be practical, as I have to order the cable and wait yet for 10 days for it to come :(
