Doodlebug - USB Isolator

[fordgtlover]

  I had an idea of using the usb logo for the legs.
 
The following is not an attempt for the actual logo, simply demonstrating the idea.
(i'm not a graphic designer, and not about to start)
 

 
If going for a real cute bug (nothing like the above) i think it would still be cool if its front feet were circular, middle one's triangular, and rear feet square, as a reference to USB.

That would get my vote. I think it's great.
 
Initially, I thought the USB Trident would surely be trademarked or copyrighted, but I can't find it listed in the USB IF documentation linked below.

i saw a product called mophie. about the size of this. that might provide even better power and make this portable. i have no idea if it is worthwhile i just figured id mention it.

I think it may help "some" usb dacs. I can't say how much it'll improve the output on, lets say, mobile phones if this was anyway possible but it's food for thought.
 
May not help people like me since I'm a desktop sort of guy.

Hi All,
 
Board received....and it really is purple!  Now waiting on Mouser and Digi-Key.

We found our first error...

The EAGLE footprint for J1 was not correct.
The footprint was set up for pins and the part
has tabs. I have modified the EAGLE footprint
to reflect reality.
 
My recommendation is to trim down the tab
to fit the hole.

Your welcome!
 
Just placed my order too (all from Digi-key).
I don't expect the board for a few more days.

my wife thought it was junk mail but i spotted the doodlebug , saved in the nick of time

looking at the datasheet, the SMT type version for J1 is a little wide for the board pads, but may work:  http://www.mouser.com/ProductDetail/Hirose-Electric/UX60-MB-5ST/?qs=%2fha2pyFadug63YtrwsEixoQPqVODSOA1lIiVOr57FQKNZt%2fo%252bCTYTA%3d%3d .

I fixed the problem for the next run of boards already.
 
I was going to use the smd version but was concerned about mounting security.
I figured the mounting tabs would be more secure.
The full through hole version I did not like, it did not route well.

probably a good idea for those that want to use manly heavy/stiff audiophile USB cables

Quick question: what's C8? I don't see it on the BOM...

 

[RagunaAsh]

Same question with R5?

my MF V-Link USB-S/PDIF converter draws a max 160mA.  I'm wondering if the 200mA DC current rating of the ferrites is enough engineering margin of error?
