In private communication, Victor has also raised the question how to turn ubb-vga into something a little neater.
I made a draft of how I imagine one could build a mechanically sound connector that plugs into the Ben's 8:10 card slot. This is what the front the PCB would look like: http://downloads.qi-hardware.com/people/werner/ubb/vga/vga-ben-front.png http://downloads.qi-hardware.com/people/werner/ubb/vga/vga-ben-back.png The board outline is shown in yellow. The yellow rectangle in the board is an opening. This is how a VGA cable would be attached: http://downloads.qi-hardware.com/people/werner/ubb/vga/prod-assembly-draft.png R, G, B, hsync, and vsync would connect at the top. The corresponding ground wires (each signal has its own ground return) would go through the opening and connect at the bottom. The shield could be soldered to the large pads on the side (not shown). The cable itself would be firmly attached to the PCB with a cable binder (black striped). Then the whole thing could be sealed with silicone, heat-shrink tubing, etc. The idea is that this be as small a connector as possible, to keep it from acting as too much of a lever on the Ben's 8:10 card slot. The VGA cable is also able to carry quite some mechanical force, but at least it's flexible. The main problem is still the soldering of the cable, which is messy work, as far as industrial production is concerned. The whole thing could be efficiently produced as a kit for assembly by the user, but many may bark at all the soldering. A partially assembled board with all the SMT resistors soldered may look less intimidating but would also be considerably more expensive. And the cable would still have to be soldered. Ideas ? - Werner _______________________________________________ Qi Hardware Discussion List Mail to list (members only): [email protected] Subscribe or Unsubscribe: http://lists.en.qi-hardware.com/mailman/listinfo/discussion
