Good morning folks.
Problemstatement
I have been using a Nextdrive Spectra (micro usb version) with my Note 3 to improve the audio quality. It's noticably better.
Unfortunately the Nextdrive Spectra has a regular micro Usb connector and our Note 3 has the Usb 3 micro Usb connector. This has the effect that the micro usb connector has sideways play. The USB Dac often looses connection because of this. It worked at the beginning, but now after a month's use it's basically unusable as long as I don't hold the phone in my hand or position it somewhere and don't touch it.

Idea
I was thinking of taking the circuit board out of the Spectra and putting it into the slot of the SPen. It should fit. If it doesn't fit I have an 6000 mAh battery which doubles the thickness of the phone so I have even more space "to make it fit".
I would need a hardware switch to disconnect the Spectra as it draws a lot of power when it's connected. Even if there is no audio output connected.
Does anyone know if I can charge the Note 3 while I have the Spectra turned on?
Implementation
Take Spectra out of enclosure
Put Spectra circuit board into Spen slot
Solder USB wires of Spectra onto charging board of Note 3
Add hardware switch to enable/disable Spectra DAC
Can this work?
Has anyone here done a Mod like this before?
Alternative
Replace micro USB connector with micro USB 3 connector. But not as "cool". I like modding hehe.

Anyone seen a cable converter to allow me to charge the Raphael from a 12V car battery when there is no access to a cigarette lighter socket?
Thus, aligator clips (or similiar) that connect to the +/- terminals of a 12V battery, and then the other end has the mini-usb connector that plugs into the Raphael. Seemingly in the middle between the two would be a 12V to 5V step down.
Anyone seen such a cable? I guess I could get a standard cigarette lighter style and break it apart and solder on some aligator clips?
um.. that would most probably result in a mini explosion that will cause your fuze to go up in flames and clouds of dark ozone destroying smoke... and maybe for you to lose a hand in the process.... I highly suggest you find a different alternative...
just my 2 cents..
go to walmart and find something like this. plugging directly to a battery is a very bad idea.

Get a cigarette lighter extension and cut off the male end. Put gator clips on the wires to the female end. Works awesome.
Be careful to get hot and ground correct.
Try one of these adapters "Lighter Socket Alligator Clips". Obviously you'll still need a HTC (or suitable) cigarette lighter charger. Only about USD6.00.
Cheers!
For some reason, my dialer started to auto rotate whenever I bring up the dialer. I fixed this through a registry edit but it still automatically switches EVERY CALL to speakerphone! How do I turn it off and is this setting an option of the phone or what? I looked every where and couldn't see how this could have happened.
EDIT: I got this mini USB to micro USB adapter so that I could use my other HTC power adapter to charge the HD2. It seems that when plugged in, the phone auto rotates the dialer to landscape and then answers all call via speakerphone. I think its somehow detecting my power adapter as a sort of car kit. Is there any way to override this behaviour?
media player starts automaticaly
i have the same problem
please suggest a solution thanks
Indeed the motorola mini-usb to micro-usb charging adapter creates this 'feature'. The screen turns to landscape and the phonespeaker engages.
No solution for that I am afraid. But there are several other mini to micro USB adapters for sale. Smaller and cheaper!
p.e.

That means it must be some sort of pinout that is grounded in the plug. Maybe I`ll take it apart to see what's going on. BTW, mine only costs USD$4 and its smaller than the one in the photo. I didn't know this "special feature" came with it for free lol.
I'm looking for portable speakers on mini usb for Defy. Is it possible, to take power supply from mini usb or build-in battery who charge on mini usb. I have portable speakers 3.5' 3 poles Creative, but with 12V external power supply. I want without external ps and without 3 poles, Defy has 4 poles and sound it's not quite good

Superportable and supersound. Builtin battery lasts approx 12 hours per each speaker.
Charging via USB, possible to use Defy (but not so wise...)
Sent from my MB526 using XDA App
@goateye yeah thanks, i'm big fan of Logitech, recently, i will decide between X-Mini and Logitech Z120
I have the x-minis too - they are great little speakers
Just got this done. I had a V1.3 charge port board. Tried a replacement V1.4 board ($55) without success. Sent my V1.3 board to Pomeroy Computing in Pompano Beach. FL. Charged me $30 and returned the board with a new jack within a week. Can't ask for better than that!
I replaced my USB connector with one i bought off ebay for a little over $1
removed old one with solder wick and solder on new.
search ebay for:

I just heated up the old solder and touched up the contacts with some new solder. My port that wasn't charging is now charging. I guess over time the solder contacts break from pushing in and out the usb cable.
Just in the interest of being thorough, the N7 jack itself (not the solder points) may also be "too loose" so to speak. I've found that the majority of USB micro connectors are smaller than my N7's USB jack, so they do not seat securely once plugged in.
One fix, dismantle the N7 and bend the jack itself. Another solution: bend your cables' connectors -- the trick is to expand a cable's USB micro connector slightly with a jewler's screwdriver. Still another, some nylon cables I've bought from China fit snugly.

I have a project where I am making a tablet wall mounted (and removable) together with wireless charging (QI Charging).
The tablet is purchased, which I selected specifically because it has a plastic back, and it is also easy to open up.
I bought this QI Receiver:
https://www.amazon.com/CUSORIENT-Wireless-Charger-Receiver-OnePlus/dp/B0713ST47Z
It has the best reviews about power output (the bad reviews on Amazon is about the connector breaking off which doesn't matter to me, as I will solder it internally).
This is the internals of the tablet, the red ring shows where I will place the the QI Receiver coil, and the blue is the cable routing.

I have tested the QI receiver with the tablet using a USB cable and it works fine, it charges. But there is a heat issue. The coil gets really really hot, to hot to touch with your hand. And this worries me, as I will place the QI receiver directly on the battery inside the unit.
I have seen several projects with phones and internal qi receivers and they are all placed above the battery so it seems to work.
Still the battery inside the tablet has warning labels not to exceed 60 degrees celcius.
So I am thinking if it is possible to use either copper tape or aluminum tape on the battery to shield it from the heat, and then place the QI coil above this.
Any ideas?
