Hola,
the MBSID is such a great project, that i wanted to contribute and share insights of how to build the control surface.
I think that names, part-numbers and supplier links of used components and photos taken of every relevant construction step will be a nice reference for you.
Be warned, this construction guide will be for frontpanels with drilled holes in the four corners. It should be adjustable for frontpanels without corner holes, but I will not cover this.
The chosen
Step 12: Create the Display Cable (...while the glue cures...)
Parts used:
Your backlit 20x4 LCD display (see Step 5 for the one I used) with a proper datasheet.
16 pin flat ribbon cable (e.g. from AVI Showtech, but every electronics shop should carry this)
16 pin female IDC connector (buy two or three to be on the safe side, e.g. from AVI Showtech, but every electronics shop should carry this)
A screw clamp, a bench vise or a pipe wrench
A cutting knife
16 pin DIL-header
