Hey,
please contact us using the contact formular on our website 🙂
we also have some bare pcbs in stock at the moment.

Hello!
I just checked your website and see that I missed the deadline for the current batch.
I am wondering if there is still one board available... 🙄
Please let me know.
Thanks!

Please refer to our newsletter which we sent a few days ago:
Pre-Orders shipping soon
We're waiting for the SMD-assembled PCBs, then we can ship the kits 🙂

Just wanted to update the thread, I received my order today.
SigmaStudio Beta 3.12 has some interesting additions, like an AutoEQ function.

Hi everyone!
I've recently built a digital input add-on board based on a design I found at DSP 01 ? latent laboratories. It's built around a CS8422 asynchronous sample rate converter, has S/PDIF and AES/EBU input plus two potentiometers, a toggle switch and a LED connected to the ADAU's GPIOs. I have two PCBs left over. If anyone is interested in the PCBs and/or the Eagle files, just send me a PM.

No, I haven't started a separate thread. It's basically just a modification of Shen's design from the page I linked to. If you are interested in the technical details, I recommend reading his project posts (especially part 7) and the CS8422 datasheet.
Hi there, I've got a FreeDSP board and have run into the same problem as everyone else with not having a Windows machine, and SigmaStudio not running under WINE. However, I may have made some progress....
....but not very much progress. This is the error I get when I try to open a new project:
To get it to install and open at all, I had to use the .NET framework (3.5, sp 1) and an XML parser (version 3) which are available in the "Winetricks" menu in WineBottler. I suspect there are other things in that menu that, if installed, would prevent this error - it looks to me like it's missing some libraries to do with drawing windows and handling user input. Does anyone reading this, know enough about Windows to tell me what those might be?

Easily, just get some TDA1387T chips (SOIC) from Ebay or Aliexpress, buy a SOIC to DIP adapter to build the DAC on, and connect the I2S to JP2 port (MPx pins, see datasheet).
Good and cheap (but only 16-bit and it is a 5V part), though there are also newer chips that can be used without MCLK like the PCM5102A (PCM51xx in general). There are many ready made boards available using these TI chips like these:
http://www.ebay.co.uk/itm/PCM5102-D...505014?hash=item1ea3770476:g:iWcAAOSwyQtVo4~H
384kHz/32Bit PCM5102A DAC, I2S input, Ultra Low Noise Regulator - DIYINHK
TDA1387T doesn't either need MCLK, that's why I proposed it in the first place. Some people like it more than sigma-delta DAC's. You can get the 5V from the Arduino on board, I think, or from the external PSU used to power FreeDSP board. Got to investigate more. There are issues with PCM5102A when used at 3.3V (output might be clipping), folks building DAC's for Raspberry Pi have now moved to PCM5122 chip which can be programmed to reduce digital gain to avoid clipping.
