I'm intending to attempt to keep to this thread for my general designs. The more way out stuff might creep elsewhere sometimes. :)
Here's what I have in mind for the first official one. I've called it the Beta because the original Alpha won't work from the published gerbers - the HDMI connector pads are covered in solder resist! When I get the boards I'll try to build one up anyway as I have a Pico 2 for it. I'll let you know how it goes.

I'm just going over it again, but I think I've found any gotchas. As usual any comments are very welcome at this stage as they are (probably) easy to fix. The enclosure is the little Hammond RM2015S, also known as the MCRM2015S. I considered using the CMM2 box but I find it harder to source and appreciably more expensive. The size isn't *that* much bigger as it's the width that is really the deciding factor.
While I was playing I came up with a PCB shape/size that will fit the above case or, by rotating it through 90 degrees, will also fit the square Hammond 1593 box. I've no idea what use it could be though. :) Possibly as a sea-of-holes board?
