GrubDAC Step-by-Step Build Guide

[TBomb06]

Wow this thread is awesome, Tom! Full of valuable information not just for the GrubDAC, but I know it will be life-saving when I start to build my Grub for the Carrie USB I have planned

Believe it or not, there is even MORE on the GrubDac site. Check out the "Construction" tab at:

Hi TomB,
 
How hard would a microUSB be to implement instead of the miniUSB?  Would it fit on the PCB as is or would more be involved?
 
Thanks,
 
St Veronus

More would be involved.  A very quick check at Mouser shows the microUSB parts to all be SMT, and there is no pads on the board to mount them to.

So would this part work on the current PCB?  Want to use cables that I already have to carry. Mouser Part 656-DX4R005J91R1500
 
Thanks,
St Veronus

No, the part that will work - a mini-USB - is clearly specified on the GrubDAC BOM:

IMHO, you need to look for a cable adapter - not a connector that's not designed for the PCB.

Fixed.
 
If you take a look, that microUSB part still uses SMT pads for connection.  The through-hole is just for mounting to the board.

tomb has pointed out to me that my morning posting skills are not so good.
 
My fix should read something more like:

Apologies for any confusion my mis-read may have caused.

Wow. Kudos! To everyone in the loop who led to this DAC++!
I love seeing the life here.
I've been... programming. Neon assembly & C, for cool stuff

but my lab was more fun!!

Hey guy - how's the married life?

 
Yep - cobaltmute deserves maximum kudos for an exellent little DAC!!

You could use something like this and wire it up

and yes,,,, many kudos to Cobaltmute this is an exellent DAC thats fun to build and to TomB for supplying a nice little kit.

Excellent tutorial...

Are those caps really electrolytics or are they solid polymers? I can barely' find any thru-hole solids anywhere so that's why I was wondering.
 
Very nice soldering. I have to work on my own for sure.

 

[cobaltmute]

The ones in the picture are polymers.  They are classed as electrolytics per the manufactures and are easy enough to find. 

 

[TheLaw]

There's not nearly as many options for polymers as there is for standard electrolytics and ceramics and such. Or so I've been able to see.
