Enclosure Prototype #1, Connector and LED Fit Notes #146

Here are some photos of the case. Everything works, but some minor adjustments might be warranted:

Regarding LED length, Just a guess I want to make. And an assumption. The enclosure inside wall is approximately flush with the LCD metallic bezel.

I can see the LEDs are way low. I left about 1/4" of lead length so that they could be extended if you want to give it a try. It is always unpleasant adjusting LED lead lengths and best with two soldering irons. You must not heat one LEDs too long or the plastic melts and the LED may be destroyed when one lead moves and the other does not.

I would suggest the following approach. Find or make a spacer equal to the thickness of the enclosure plus perhaps the radius of the LED hemisphere which is 5/2 mm. This would give you the assembled result that the LEDs would have a hemisphere of protrusion.

Reduce light cross talk.

I would also get some black paint (nail polish) and blacken the cylindrical walls of the LED holes. The paint should be chosen to be compatible with the plastic of which the enclosure is fabricated and about which I know nothing.

@RobertLRead I suggest a change to the issue name. From: Case orifice alignment is almost but not quite perfect...#146 To: Enclosure Prototype #1, Connector and LED Fit Notes

I've changed the name. It is a low priority for me to try to fix the leads at present. The nail polish idea is a nice idea--Of course, a colored plastic would also affect this, so I consider this much lower priority than the software I am working on.

Lee added GPAD in Prototype Enclosure image to the main README.md at the GPAD root.

@LokiMetaSmith Do you need more information for enclosure work? Can this be closed next meeting?

  1. Enclosure USB header slot needs to be moved down towards the board 1mm, and 1mm away from the center of the board.
  2. The latch on the i2c header needs to be evaluated, in terms of interference with the enclosure. This will require making a test cable.
  3. LED holes need to be expanded to allow LED's protruding

The files with name/ number V105 meet these requirements.
