Hi Jiri,
Thanks for posting your pics, very nice set up indeed!
About the powering issue you and Bud mentioned, could you please measure your power supply next time it happens? Just wondering if that's not the power supply drifting.
I'm sometimes asked whether there's a boxed Najda available.
There's actually a Japanese manufacturer (S&K Audio) making a full unit in a classy white chassis. More information here:

Parallels for OS X
Not free but Parallels will to the job, and if you run in Coherence Mode you can mix windows and mac application on the same desktop.
Try take a look at the image of my desktop. You will see a mac desktop with NUC running in what looks like a normal os x window.

Hi, here is my build of Najda...
unfortunately can't comment on sound...
but have one question, as I use I2S input and I2S outputs, and mute doesn't work, I nead some advice how to mute or disable one channel at time...just to see did I connect everything right ...as channel one to L twitter, channel 2 to R twitter etc. ?

Glad it is working for you I think I called it host extras instead of extensions.
One thing to note is that the virtual system will grab any USB device that is inserted after it is started so if you need the host system to use a particular usb device it needs to be inserted before the virtual machine is started.

Apperently you have to list usb devices before the machine can use them.
Not a big problem once you figure it out.
Here is where you find it under "settings".
Then edit. You will find the "Najda" using the command promt and a line that
I got from a friend last evening that I dont remenber now.
The command might have been "VBoxmanage usb host list", I think it's right.
You will find "WAFN0007" on one line. If there are parenthesis, use whats
inside of them.

Hi,
I'm another one looking for a nice Mac solution for NUC. I did a quick test with Wine and it seems to be able to create the user interface nicely, with editing options. However what is missing obviously is the connection to Najda.
So serial communication is not working through the FTDI-drivers to the OS X side. I didn't have time to invest for now.
How about NUC2 was a node.js application running on a Raspberry Pi permanently attached to the Najda and accessed through a browser or a dedicated iOS / Android app with live editing?

An externally hosted image should be here but it was not working when we last tested it.
So,
it seems Wine is out of the question in this case. I tried adding the symbolic link to com1 in ~/.wine/dosdevices/ which is the common suggestion, however this did not work. This means that Crossover, which is based on Wine is out as well. So a virtual OS seems to be the solution.
So as suggested above I got it working with Virtual Box 5.0.14 running Windows 7. The host is running OS X 10.11. I added the extensions pack for USB2 support and then finally the USB device, this way Virtual Box was able to configure the USB device automatically, no command prompt or manual configuration needed.

Dsp overload?
Now have the unit working after sending it back to jc. Having trouble with the unit display shows 311% and red. Seems to happen if I switch an amp on or off, maybe some kind of current spike. Any thoughts appreciated. I guess if I turn the amps on before Najda and off after Najda is turned off. But would be good to understand why that happens.

Certainly doable, in fact I've made a few attempts towards an approach like that myself (albeit with limited luck).
Since there's no official documentation anywhere on the communication protocol I suppose we would have to apply some sort of a d2xx proxy or sniffer to extract the actual communication protocol between the board and the PC, and then emulate this same behavior under linux. If we knew the details of the protocol it shouldn't be to hard to write a restful gateway that does what the NUC application does (Assuming most of the low level logic happens in the onboard MCU and the mcu<->nuc protocol is somewhat reverse-engineerable), and then put a nice little web SPA on top of that.
I recall I had a quick chat with Nick about this a few years ago (Holy ****, it's been two years already!), but I understand (and respect) he was a bit hesitant to start documenting and supporting the protocol as-is. Potential can of worms etc.
