dissection of SD card connector

I opened up my blue angel, and I'd like to make a SD socket extender.
I've soldiered the 9 SD pins to an external SD socket, however, the device doesn't detect the card. there seems to be a way the pocketpc identifies when a card is inserted.
is there a way to override this ?
or any other idea's how to make an external SD connector.
Sounds to me like you may have burnt out something on the Wizard motherboard from the heat of the soldering iron as the Pocket PC detects an SD card by the power flowing through the card, i.e. when the conenction is complete it detects the SD card.
when I plug in a memory card by itself to the ppc, it detects it fine.
there seems to be some kind of switch on the inner side of the sd connector, but i cant be able to figure how it works and what its connected to.
there are 9 pins yes but on the right side of the card there is a pin in the connector that gives power to the whole socket when the card is inserted. that was you dont fry the card when you insert it. its basically like an on/off switch
hello
How do I bypass that switch ? (or shouldn't I ?)
I'm working on a carppc (which'll be perm. mounted in the car), and I'm making an extention cord for the SD socket..
honestly i wouldnt extend it over 6-12 inches. you will get alot of signal degridation if you do that. if you want to bypass it then wire up a switch. just remember to cut the switch off before removing and inserting
yeah, i opened up the socket itself, and there really is a switch.
i made it about 6" long, so it ought to be ok.
as for the switch, any idea why its necessary ?
- it doesnt exist on (most?) sockets i've seen.
- also, the SD guidelines specify that the power and ground pins should enter
first, so the card wouldnt fry up, so why the hell the switch ? it makes things a lot more complicated, also, getting the switch out of the socket, is also not so easy.
in the meanwhile, i've kinda funked the screen's flex cable.. can this be replaced ? or do i have to get a complete new screen.. ?
I"m guessing all the wires would need to be exactly the same length.

Splice a microSD reader onto internal USB?

I've been thinking to trying something, but thought I should get some input first...
I'm considering soldering a small ribbon cable from the contacts on the back of the Nexus 7's microUSB port and running it up to the space where the rear camera would have gone. I think there's enough room for me to insert a small microSD card reader and still fit the back of the case on properly. I've soldered a lot of small components, so I'm not concerned about the about the process. What I need to know is if this will interfere with charging. I know that the port can charge and transfer data simultaneously, I just don't know if it can do this is the data and 5V are coming from different sources. Any feedback would be appreciated. Thanks!!
I'm not a pro at this stuff by any means, but I do have an idea.
Maybe you should just grab a cheap y-splitter + otg first and see if you can charge while using a microsd reader?
Good idea. I have an OTG cable, so now I just have to track down a y-splitter.

Will this work?

I have a 2tb USB powered external hard drive, the phone doesn't have the power output to load it up.
If I was to plug it into the above item, with the item plugged into a power socket, would it power the hard drive without frying it?
Would it also charge the phone /tablet?
Thanks

Work. It is irrelevant to the question though, neither my Windows 8 tablet nor my phone can access it which means I can't give my laptop away until I have a solution - Will this fry the hard drive if I plug it in or should it work just fine?

[Q] Can ur phone use internal and external battery at the same time? 2horizon pins?

I found that video:
https://youtu.be/PP9wygsHO_Y
In that video, they put a metal that connect to 3 thing: 2 horizontal pins at the back of the phone, the negative and positive of the internal battery, the negative and positive of the external one (inside the case). And I think that the phone can recognize them (or the phone will use both of them by someway??)
So my question is how can it work? Anyone can explant for me please?
And what is the function of 2 horizontal pins of this phone? What is it doing? I know 3 vertical pins ia for wireless charging or for s-view.
Thanks!!!
