Faceplate mod = MicroSD card storage?

So I'm thinking to myself, this faceplate should be more useful then just a cosmetic attachment.
If you were to carefully cut out some small chamber into the back side of the faceplate you could probably make a way for storing Micro SDcards.
Seems like a simple enough an idea I thought, not sure if the magnets in it would effect the cards tho?
Why do this? 128s are still pricy, even 64's of a good brand are too. You could store a ton of movies/videos on a bunch of cards and always have them handy.
If your creative enough you could probably make enough room in the back of faceplate to glue in 2-4 of these:



I wish there was an OEM solution but I'm very tempted to attempt some sort of mod.

An other idea for modding the faceplate would be to some how instal a small camera, tho, not sure where someone get the hardware to do this tho... A professionally made HD camera attachment that would replace the shield however would be cool tho!

I think its a good idea but I'm wondering if the magnets would corrupt the card also. Electronics and magnets don't mix well.

Flash memory isn't really affected by magnets because there are no magnets used in it. You're thinking of floppies and HDDs.

Correction: not affected *as much*.

I would expect the card to work fine still. But magnets moving near any electronics induce a current, this can be the wrong polarity for the card and damage the gates, it could just enable a card read (with nothing to read to), it could reset a memory cell or it could do nothing. The latter is most common but the prior 3 are feasible and can occur.

I would try this, but the fact of the magnet may cause damage scares me... Right now I have 3 32GB cards, one inside and 2 in a little cardboard cut out taped to the back of my shield, pretty easy to move them in and out...

I looked this up to see if I was correct, and I was.

The only major problem with magnets and data storage comes from the hard drives that are not solid state drives. The problem is caused by the fact the this type of hard drive uses a magnetic field to read and write to the drive.

Under normal conditions moving a magnet past a coil of copper magnet wire by hand will only get you millivolts.

I am of the opinion that the shields magnet is so weak that even if a micro SD card could be affected by a magnetic field that it would need a much more powerful magnet to damage it. To be realistic the magnets in the shield faceplate can't even hold on to the fridge. When you take a piece of metal and drag it across the back of the faceplate, you will notice that there are actually too small separate magnets in the top and bottom centers of it. Giving you plenty of room to create a cavity or two, away form the magnets themselfs for the micro sd's.

Nice observation, I will test this tomorrow when I get mine! I'll leave one of my ancient 256mb cards in there for 5-7 days and then test. I think that under there could be a sweet place for SD cards great idea!!!

Yeah, the magnets not only affect the data itself, but were also bad for HDDs w/ platters, as the spindles could then damage the drives due to the magnet, iirc...


Regarding the faceplate, is the magnet in the screen or the faceplate? (Or both?)
If it's in the faceplate, could 3d-print a replacement faceplate to hold microsd cards (or even have a cable running from faceplate to back of Shield if rigging up something even more complex), and then fashion some non-duct-tape method of attaching the faceplate back to the Shield.

I have had 0 issues with magnets and memory cards/ssd/flash drives. The link from the post you quoted tells why in better detail then I will.
HDDs use a magnet system to read and write the to the HDD, flash drives/ssd/memory cards don't work that way.
