Hey Erin

No hurry for the pics ( do you ever sleepIt must be 2am in Oz )

Every days a school day! man what a can of worms!

I'm still going to try and pick up a WD mini on the way through Singapore in a couple of weeks. Once settled back in NZ I will have a look into another DAC project as you have listed, I much prefer a kit or scratch building not mad keen on the cost or lack of input on ready made kits.

Anyways thanks for the advise and I will keep an eye on your thread.

Christmas is coming!! Wife might splash out on a BOM from Mouser!

Cheers

1) open the case by removing the 4 rubber feet on the bottom of the case then remove the screws

2) remove the board

3) there is a metal EMR shield covering the IC's. You need to remove this shield to get access to the data line of the i2s.

Removing the shield is a bit difficult because of the lead free solder used.

there are six tabs attaching the shield to the PCB. I ended up cutting the centrally located mounting tab and then:

using some fresh solder applied to the next mounting point, and holding the iron tip in place, pry the shield away from the board until the mounting tab is free.

Repeat this process on the next tab until the shield is free at one end and keep doing this until the shield is held only by the far end centre tab, then cut this one off.

Now the shield is removed. (*note: it is probably possible to carefully cut all the tabs, rather than removing with the above method, as the shield seems to be there so the device passes EMR emissions testing, rather than to protect the circuit from interference. The unit works fine without the shield.)



4) there is a SMD resistor array of three resistors. the resistor furthest away from the DAC, and closest to the microprocessor is the one that has the i2s data line.

here you can solder your wire.



5) next to the USB port there is a blank header on the board, here you can access the other data lines.

The pinout of the header starting furthest from USB is as follows:



pin 1 3.3 v



pin 2 gnd



pin 3 master clock



pin 4 left right clock or (word select)



pin 5 unknown - but it is not data - that’s why you have to remove the shield!



Pin 6 bit clock



Now you can connect wires to the bit clock, LR clock and Data and connect these to your DAC

Enjoy!

Hi Erin

Thanks for the pics, as they say a picture tells a thousand words.

Cheers

Dagwood,
You are most welcome.

If you want to use a media player as a transport with i2s with your Burr Brown Dac, the TEAC wap2200 Teac WAP2200 : what's inside?
( i think) uses EAIJ (sony format) i2s which should interface directly to your PCM63 DAC. ( but do your own research to confirm this)
Although I don't know what it sounds like and whether this is a viable alternative???

I can highly recommend the WD mini as a genuinely audiophile stand alone HDD music source. Although it sounds better with a flash drive than with the HDD.
I will have to try a USB isolator ADuM4160 USB Isolator board, bare PCB and kits « Circuits@Home and see if this makes an improvement when using a HDD.

Perhaps this is the end of this thread?

I think my question is answered.
There are many people who want a stand alone HDD source of audiophile quality.
What I have built achieves all that I wanted.
I don't have to have the computer turned on to listen to music.
It sounds about 20 times better than my best attempt at a PC source (cPlay + CMP - fully optimised ) It beats or equals many respected CD / SACD players. It gives genuinely good audiophile sound.
A downside is that although it will play 24/96 high resolution files it only outputs maximum 48khz.

I use a little 7" monitor bought from ebay for about $100 connected to the WD mini for viewing the GUI.
There is a remote control. It interfaces to my TDA1541 DAC. I couldn't be happier.
Now i just need to put it neatly into a box.

I cant recommend this highly enough.
I think this project would bring much enjoyment to many people.
happy DIYing!

Hi Erin,
That's a great solution for having my flacs played on my TDA1541 DAC.
Now I'm using PC(foobar)->PCM2707->I2S->TDA1541A

Are these mods also possible on the WD TV HD ?

How you are playing music now, is virtually the same as what I was doing.
The WD mini sounds so much better than that.

The new WD HD media player uses a different chipset so I am unable to comment on that. I do believe that it is possible to strip the i2s from HDMI, but I have not done this yet. I think the above mods to the WD mini can be done to the WD live as well, but I am concerned that the network chips in the Live may add some switching noise. That is why I think the Mini is so good, because it is so simple.

Thanks, then I will try the WD mini, for 40€ it's a no-brainer and it even has a remote :-)

Hi, Erin!
Maybe the problem with the way of power supply of the HDD, I mean from the USB or external PS? Have you tried both types?
