What is the hardware that u are using to interface the camera with the pc?

Just wanted to mention I hope to publish a updated version of Atmels ISI driver with tcm8230md and tcm8240 driver module for avr32linux. It has all the cameras registers available in debugfs for hacking directly from linux userspace.
It still has issues but it's also a lot of fun.
It makes it a lot easier to fiddle with these cams. (as long as you have a old ngw100 card lying around that is...)

Even a sketch would be very useful.

If this board was to be made professionally I'd ofcource do it 2-sided to tidy up the routing. Then I'd add silkscreen to connector-side so one would always have the pinout of the connectors available.
The large 1206 resistors are for all spots where user might want to change stuff. Only the power-system is set up with tiny stuff as that will be a 1-time affair. (0603 and 0805 for power system.)
