First of my revision 2 PCBs

Mostly working well. There's a couple of minor mistakes, but everything mostly seems to work insofar as I've tested it. Annoyingly, I ordered the wrong size oscillators after sending off the PCBs, so the wires are heading off to the master 16MHz clock. Amazingly, there doesn't seem to be any interference!

Updated revision 2 schematics

My friend reenigne suggested I have separate audio and video ground paths, so I've made that change and decided to do the same with the USB ground, even though it wasn't explicitly required.

Hopefully this will all work now, I've sent them off to be fabbed! \o/

I think I've finished the revision 2 board layout

So, I've been VERY quiet recently. It's not that I've not been doing anything on this project. Quite the opposite...

After quite a few late nights, I think, or at least hope, I've finished my new board layout. I can't see anything obviously wrong with it, but neither did I before I found a very obvious error about an hour ago... :o

Busy doing a new layout

So, I've been pretty quiet recently apart from posting a few links. I'm actually busily routing revision 2 of my board and hoping I'll be able to send it off this week to have some made up. Hopefully this will fix all the issues I found on the previous board as well as having a lot more expansion options...

I'll post some pictures when it's finished! :)
