Ok, cool.  My M8 should be available for pick up next week, so I can finally test my cables :)

I can't help but think that sugru ( http://sugru.com ) would be perfect for this diy

That is what I used in the tutorial.

Been a while since i read the original post, forgot *doh* :(

 

Just thought of it while seeing the various solutions posted.

  • Thanks for this FraGGleR!

I used your tutorial to make my first OTG cable. It was my first time using epoxy putty as well; had no idea it'd be so sticky.

 

 

 

It ended up being a little too long, so it's gonna bother me enough into making another one soon.

Hi!

 

Bumping this old thread up here... 

 

I'm also into making a USB OTG cable for my portable rig, but there are a few things I wonder. Do you need any special type of cable for the digital signal to be optimal, any directives concerning impedance etc? Also, is there any need for shielding on such a short cable? I reckon you didn't shield yours, but most OTG cables on the market are shielded. Do you have any problems with EMI? 

 

Thanks in advance!

No special considerations were made for either given the short length of the cable.  I don't get any audible interference with the cable, even when using LTE data to stream music from Pandora and don't know what improper impedance would even sound like for digital streaming.  If you are concerned about either interference or impedance issues, you can always use a cut portion of a standard USB cable and simply reterminate for your purposes.  Having made nearly a dozen USB cables out of different materials, gauges, and geometries, I don't think even things like out of spec impedance audibly impact audio streaming signals.

No, especially not at this lenght. But the cable should be appropriately sized and easy to work with, the solder pads on the micro USB are quite small... Oh, and make sure you get decent micro usb connectors because bad ones will damage your phones usb port!

I don't think there is. Most overpriced "audiophile" USB otg cables aren't shielded either, which I think is rather funny.:D

Not at all.

Thank you guys! Maybe I'll make a simple OTG cable then... If I do, I'll post a picture here smily_headphones1.gif

Hi again, went for it yesterday and made a slick little OTG cable. Here's the result:

Nice! I just recently got an Audioengine D3 and was also thinking about making a similar otg cable. Which dac is that in your picture? Dragonfly?

Well done!  Nice braid.  I have a LHLabs GEEK coming that will need another one of these.

That's correct! Packs quite a punch for it's size, great for a really portable setup...

i just received these from ebay yesterday, extremely disappointed with the fitting. The fitting is so tight i am scared that i will spoil my phone by just plugging it in. Pulling it out requires exaggerated strength too.

Anyone who obtained better stock from ebay, care to share the URL to the item?
