Hi,
I haven't updated as often since we've been deeply involved in designing the VCA I/O card. The last one I showed was the Ultimation card.
After some tests with the Ultimation we decided to go to a even more evolved design and more robust. We weren't very happy with the S&H results and also the lack of autonomy the I/O card had, since it was very dependent of the motherboard for powering and testing. We've addressed this issue on the VCA design which is now 100% autonomous, with it's own powering capabilities and micro-controller. We've also abandoned the simple S&H and went instead to a more traditional AD/DA design.
We're going to print this new design in the VCA format in a couple of weeks and test it live at Andy's/Sintech in UK. If this test goes as planned we'll be merging this design back into the Ultimation card.
I know this is taking an awful lot of time, but these things take its time. Remember we are doing this as a "hobby"/community project. Unfortunately we don't have the luxury to be 100% dedicated to it to deliver as fast as we desired. But we're getting there, and if you patient, I am sure we'll have a very good community alternative, designed with lots of love and good vibes!!!
I'll do soon an update with the VCA design.
Thanks for asking!
Cheers,
Artur
