Reader Internals 2.0 (pics!)

Update: The pictures are back - you find them attached to this thread. -- Alex

Hey all, just thought I would share these with you. Taking this thing apart was pretty easy. The right side (plastic) silver bumper pops out after unscrewing the one screw on the back, then sliding a slim knife or screwdriver under it (careful, they are fragile!). The Left side bumper has 2 screws holding it in place under the SD card flap. Once those are undone you can pop it out in a similar fashion. There are 4 screw holes on each side of the reader now. Unscrew those as well as the two near the port at the bottom and lift off the back cover (it is hinged at the top). The internals are screwed to the front faceplate. I did not have the time to dissect it any further. Everything went back together the same way with no problems. I did not notice any unused ports or anything fun like that on the motherboard.

Awesome. Looks like DIY battery changes will be pretty simple.

Thanks!!

That rug looks like a good source of static electricity. Next time, disassemble it on a table in the kitchen. The kitchen table and floor should be less likely to cause static buildup.

(I used to be a repair tech at a computer store, and they warned us about electrostatic discharge, a minor-but-not-insiginifcant problem.)

Hè hè.... look at the power connector. Not enough room to place it on the original PCB Sony? Nice solution though.

Anyway, if we ever need to replace the battery you wouldn't be able to replace it by the original I think. It's a Sony battery so they will prevent selling these seperate. Of course there will be replacement batteries because there are enough online stores for replacement batteries. As long there will be need they will provide.

Looks like a pretty standard Li-poly battery. There's a bunch of outfits that sell similar ones for the iPod and PDA replacement markets, so I'm betting they will show up eventually for the Reader.

Be tough to sell them right now though. The usual usual sales pitch (and what made me replace the battery in my Palm T3) is longer run time

I think the power jack layout may be a "feature." A significant cause of early gadget mortality is walking off with it still connected to the power cord. If you're lucky, it just pops out the plug, if you're not, it snaps the jack off the board internally. If the jack is on the main board, this means big bucks.

The way this is laid out, it would just trash the little sub-board, which would be a very easy and cheap repair.

Or maybe it didn't fit

Cheers,
Bob

Thanks Lint--Very cool pics.

Wonder what the boys & girls at SONY think of you slicing open their baby.

Knowing that the shell can be opened like that, someone might conceive of some interesting hardware hacks

Battery replacement

Thanks for the pics!
About the Li-Ion battery: could you give us the dimensions of it?
This would allow to guess the capacity and consider possible replacements.
Prismatic Li-Ion cells from different manufacturers tend to have similiar
dimension and capacity ratings, e.g. Panasonic OEM cells.

i thought of painting the outer case (which is metal btw) but I think I will wait. I really wouldn't mind a nice texturized black case I hope others more knowledgeable open their readers and give a better analysis of the internals. I really was only looking to contribute to the scene by opening the reader for pictures. I'm sure others will give more info in the future.

Hmm. In the 5th of the "additional photos" is that two 64MB flash memory chips with an open spot for a third? Maybe some internal memory expansion would be possible (though with 1GB SD cards selling for around $20 now I'm not sure why anyone would want to).

Memory chips

Do you mean IC1112 & IC1113, with IC1114 missing?
These aren't flash memory chips, these are only simple lowly bus drivers
The flash chips are the large towel-shaped 48pin chips on the left edge of the same picture.
