From a bit of a break

Belated Happy New Year to any one reading this before January runs out.

I have not done much - if anything - on this since November. I had also forgotten where I was.

So I have an updated DACOne design - this is using the 16 channel ADAU1966 or ADAU1966A. I still need to track down the issue with the CM voltage on the current design being lower than expected. 

I have a new DACTwo design almost ready. Given the ADAU1966(A) parts are now hard to find or expensive, this new design is an 8 channel design using the AKM AK4458 device.

I am still working on the CoreOne XMOS design. I had a new layout, but the track work wasn't good. The USB and Ethernet are the big issues. I would like to keep them on the same edge for mounting in a case, but the device pin out puts these on opposite sides of the IC. Other track work was long with the connector placement and PSU layout I had used so I am redoing this again.

There are other issues I am seeing as well now with component supplies, both in my hobby and professional design work. Generally electronics components lead times are long now. Lead times for some simple passive parts can be 3 to 6 months or longer in some cases.

It has been having an affect when trying to design for my hobby projects, or even volume quantities. You may choose a suitable, fairly generic part with appropriate size, cost and foot print only to find, by the time you wish to build it, that every supplier has low or no stock and you have to wait 3 to 6 months or change the design.

I have limited development and play time for this project at the moment, and for the foreseeable future. However it will continue. I have another project that I have been working on for nearly a year now. I need to get finished in the next few weeks as it is not for me. Once done that will free up some time and space,
