ADC Adapter Board with Minor Bugs

I finished up my ADC-DVI-VGA version that fits in an Altoids tin and sent it to BatchPCB. I prefer to use American labor, so I got a quote from Advanced Circuits, but the prices work out: it’s about $400 to start at any quantity (e.g. 10 is about $40 each) down to $10/each for 100. I couldn’t justify it in case (a) there was a bug, and (b) whether I could sell more than 5 to make up for it.

While I was waiting for it, I fiddled around in the design to make sure it was right. I realize I should have checked the design first, and, running the electrical rule check (ERC) I found I had left the DVI connector ground unconnected. D'oh! Fortunately there are half a dozen other grounds which (usually) get all tied together, so I was lucky and when I wired one up, it worked perfectly the first time. (Note that this is the 2012-Feb-29 version with only 4 copies around.)

I'm updating the design and will send it off to BatchPCB and open it up for sale. I'll also post the design files as my intent is for this project to be an Open Source Hardware (OSHW) project.
