The SkeletonDAC - Page 3

For the Digi-Key BOM, the only inductor I could find in that footprint was 1uH, not 10uH.

Will the 1uH be of any use or is the value too low?

Done

Thanks for the clarification.  As I do more of this stuff I find the circuits are starting to make a lot more sense.

Here is the BOM on Digi-Key.

I think you have to be logged in first to see it.

Let me know if it works.

I tried to see the bom and it just sends me to the BOM manager page.  Even if I'm logged in this still happens.  Any suggestions on how to see it?

It might not work...check this wording in the BOM help:

"Click the link in the "Public/Protected" column associated with a BOM you authored that you would like to change the access rights to. Access restrictions include public, where anyone in your company that has a Digi-Key Web Customer ID can access them, and protected, where the BOM creator can specify who in the company with a Digi-Key Web Customer ID can have access to the BOM."

It sounds like you can only share a BOM within the same company name.

Anyway, the BOM is listed as "public" and the BOM ID# is 28657.

Thanks cobaltmute, that sounds like the best plan.

I did a little cross referencing between Mouser and Digi-key and will stick with my Mouser BOM.  Digi-key seems to be out of some of the parts and for others requires a minimum of 10 pieces.

The BOM list multiple choices for the output caps, depending upon your preference.  I have not put the case on the BOM, but it fits the Hammond 1551H.  If you are using the Hammond case, you need to watch your output cap height - approx 10mm is max.

 

And I have 6 boards to give away as prototypes.

Rules are similar to what I did with the pupDAC:

• One board only per person
• $5 CDN shipping to anywhere in the world

  

Looking back at the thread, the following 5 expressed interest, leaving one board
    Armaegis
    nikongod
    c12mech
    onyu
    RedLeader

 

My only criteria is that I'm looking for a least one build of either a SPDIF or Full build, as I don't have the right stuff to test this myself.  That means until I hear what the people on the list intend on building, the last board available will go to someone who expresses that they will build and test the digital out.

 

If those that have expressed interest can confirm continued interest and build type, either in the forum or PM, we can get this moving along. 

Hey guys - my understanding is that not many of you have responded to cobaltmute.  Please remember the PCB's are FREE.  Cobaltmute is only asking for postage.

I am also interesting in building cobaltmute's r1 power supply.

If it works out for him, I wouldn't mind receiving both in the same parcel.

I haven't looked at the BOM yet, but I assume it's pretty cheap, and I need more SMD practice anyway.

I'll take a look at it when i get home from work.

EDIT: I also wouldn't mind testing out SPDIF.

I think I got all the stuff from Mouser for about $20.  Not including the dac chip, I got it from the TI sample program.

PM sent to cobaltmute earlier today.  Would like to build one asap.
