I see you posted this on Youtube recently: https://www.youtube.com/watch?v=mRyBnOVRm3A

Will you start selling home made DSUs soon? :-)

Hey! thanks for posting it here, i tried but there was some issue with the forum and i couldn't do it.
That was indeed an advance and finally could transfer valid data but just a few pixels, the interface proved to be very slow and overflowed too easily.
The project is not dead and it will never be, is super slow yes but once i manage to store those bits that DCS is ready to shoot.
Right now i'm out of the country once again but when things stabilize i'll be giving it some progress to the DCS.
Thanks to everyone that are following the project

It is known that digital imaging testing must be done with the classic picture of Lena Söderberg https://es.wikipedia.org/wiki/Lenna
I don't have one of those so i draw my best on a CF card case.

Then i put myself to code and to wire the cheapest and chiniest logic analyzer i could get.

And lol and behold!! the first recognizable image from the modern recreation of a DSU.
With all of you... Lena:

Yes, it is a mess.
The image looks like is melting due to a very wrong timing of the CCD,
It is skewed due to the analyzer missing some bytes on the stream because it just decides to ignore my clock signal,
Also because of missing bytes the color information must be discarded,
Exposure is quite a hard thing since i can only get a reading if i expose it at the same time i'm reading it so i have to expose it faster than the sweep is, that means, using a flash.

But hey...
i got to make a picture of my mom's cat

Stay tuned
