Re: CEM3379 Stereo VCF assembled board

Great work!

Funny; someone here talked about the CEM3396, then nothing...

And without a word you come with the CEM3379, board already done! That's cool.


Did you plan to connect it to a Core?

Did you think about a front panel?

Doku?

Based on the shruthi-1 original filter board :wink: - Great to see a stereo version for connecting AOUT modules..! Thanks a lot.

/profile/7584-antichambre/“>@Antichambre This an old project, but I’m still not finished the control surface. Enclosure has taken from old soviet “MICRO” calculator Elektronika MK-44 but it has no main PCB, so I’m still searching for another one to take keyboard from it for more authentic look /emoticons/rolleyes.gif” title=“:rolleyes:”>

Rio asked me for the project files, so I've uploaded everything to public. 

Yes, design is based on Olivier's original Shruthi-1 CEM filter board, other parts is quite standard except OLED - CORE8 PCB with MidiboxSID v2.042, Stereo SID6581 PCB and AOUT_NG. PSU is taken from old DVD player - +5/+12/-12 volts, CEM VCF powered with +12/-12V.



The only one noisy part is OLED's boost converter, I was thinking of powering it directly from +12V rail, should fix the problem.
