maybe that could help you.

(btw obviously that's not just two connector heads and some wire, the circuitry is in the bulky VGA end)

Re: VGA Support/Mod??

<t>you can buy or build your own circuit board that converts HDMI to VGA.<br/> <br/> there would be no sense to include VGA on the Pi itself.. if you want VGA then you should start asking where is the DVI-D? where is the WiFi? where is the mini PCI-E slot? where is the SATA connectors? where is the....

Re: How about this for a case.

That's not a case, it's a piece of plastic molded around a circuit board, rather ambitious I'd say..

(Not trying to shoot down your project, but you will see what I mean once you have your RPi, and that case cracked open next to eachother.)

Re: Which Power Supply?

Yeah, it's unfortunate you can't really give the green light on a product that you can't physically test..

You can really only guarantee "it will work IF it does what it's supposed to do".. sadly that is not the case for many devices on the market.

Re: Got to love this...

It would be interesting to know, how big is the "2:nd batch" going to be, and when will it be / was it done being manufactured?

This way I could myself get a more realistic grasp of when it will be available to me. Probably better than the suppliers "guesstimations" at least
