Hacking m3 m3i0 microsd slot

[sumarth]

is the card really supposed to go that far in, or is it a manufacturing defect
the flashcart works, but its a pain to take out and put in the microsd card

sorry for the crappy pic, i used a DSi camera that i couldnt hold still

 

[sumarth]

wow that pictures bad

Kinda hard to tell from the picture how far it goes in...

Aside from that, you know the slot is spring loaded right? Just click it in once and press again to get it out. Is it hard to get out because you're trying to get it out with your fingernail?

 

[sumarth]

yeah, its spring loaded,
i have to really push with the end of my fingernail, and it clicks, and comes out. if i didnt use my fingernail, i wouldnt be able to get it out. its about as far in as the middle of the curve in the plastic

Ah, as to answer your first question about the "manufacturing defect", I never had a problem with a M3 side loading revision I had my hands on at one point. You probably were unlucky and got a cart that had the slot too far in.... But at least it works. Or maybe they're all the same and you're just having your own problem with it, but I'd doubt that.

On my m3i0 the memory card edge is just fractionally under the edge of the flashcard
& you can't see any of the flashcard circuit board underneath, which it seems to be on your photo

 

[sumarth]

the red line is where the microsd's edge is when its clicked in
its certainly different from most ive seen

you can see the edge of the circuit board when the microsd in in

Youch - that's really is far in

Does the flashcard work OK even though it is in so far - if so I guess Wingless is right, you were unfortunate in getting one that's has the slot in too far compared to others

it works great still, so i dont mind as much, but this shouldnt mean that its damaged or anything, right?
i bought it from dealextreme

Mine goes about that far in, doe not cause any problems for me anymore, other then the fact that if I have cut my fingernails in the previous few days, i tend to use a toothpick or key to push it in and active the spring for inserting and ejecting the card.

I figured it was my fault the card went so far in. When I first inserted the SD card while trying to flash the thing, I actually pushed it in and up over the spring loader and got it stuck in there. Had to pop open the card and gently work out the SD card with some jewelers tweezers.

I have 5 more coming in the mail for xmas gifts. So, soon, I should be able to give a better idea of how much variance there is in the slot placement.

 

[sumarth]

mine was like that when it came

All 5 of the new ones are like that as well. If older zeros do not go in that far, I'd say it was the newest hardware revision.


One thing I want to point out to people who are first using this card, they seem to ship with the spring in a weird "locked for shipping" position.

The first time I put a microsd into any of my zeros I had to push it in much further then I expected, with no spring feeling. the first two I did I panicked and pulled back out with tweezers a few times before I got them in far enough to unlock and engage the spring.

After that, they work exactaly like you would expect a spring loaded slot to feel. A lil springy resistance on it's way in and a clear click-lock push back a smidge feel when they are in place.
