Bluetooth or WiFi DS cards for offline use?

It is a bit expensive I thing, that price buys me 8 8GB cards.
Taking the card out of my camera and plugging it in the PC only takes 5 seconds.
Difference 59 $ for 5 seconds work.

BTW I have a lot of stuff ordered from ebay as of November 20 and November 21, and much of it has not arrived yet..
China mainland AND HongKong.

Christmas delays?

I've noticed that some Chinese vendors get stuff to me in a week or
slightly more. They refer to e-packet as part of the shipping. I don't
know what that is, but I think it means the items are already here in
the US or somehow they get it to the US very fast and then it is carried
by US mail. I find the mail isn't too bad these days. In fact, I use
USPS Priority for DigiKey which is typically 2 days while UPS takes
four! I've already gotten everything I ordered from eBay this month,
some of it weeks ago.

My last eBay order that came by FedEx is still listed as "pending
pickup" after two weeks! Bloody idiots! The seller charged $25 for
shipping too.

I don't think it's something that can be figgered out.
If you wanna work in the existing environment, you gotta emulate
a file server/router with DHCP server and the whole nine yards.
The SD slot in a camera simply can't supply enough power to run that.
And the network gets really unhappy if the network controller node
keeps falling asleep.

It should be easy:

a. The card becomes not a controller for the whole WLAN but just a
participant.

b. In order to make it learn the network access the card is inserted
into the SD card slot of a PC and gets told the log-on data by the user.

c. Card is now a shared drive just like other PCs on the WLAN can be if
the respective permissions are set.

That's it.

I can't find a link, but I think I remember reading about cameras
with built-in wireless that may do what you need. There were some
ads for the microsoft coffee-table pc showing you could just set your
camera on the display/table and it would display your pictures.
They do that kind of thing regularly on TV like "Hawaii-Five-O".


There is a Samsung but it's a small digital camera. I need more
professional photography where lenses can be changed, currently using an
Olympus E-PL1.

I've had stuff from China (DealXTreme) get here in three days, though
lately it's more like seven. My laptop got here in less four.

My last two orders from Digikey took more than a week. When I lived in
Vermont, I'd get the UPS packages on the third day (an order Sunday
night would get there by Wednesday). The last couple of orders were
shipped DHL from NJ to Atlanta and then the last thirty miles by USPS.
The USPS leg took one of the seven days.

I had to ship the laptop back for service. One day there and one back
(two weeks there :-!) via USP next day. Good but expensive!

Sounds like a complaint to FleBay is in order.

Not unless you modified the camera firmware. Don't forget that the
camera only knows about SD memory cards, not SDIO cards.
a. The card becomes not a controller for the whole WLAN but just a
participant.

Yes, DHCP/NFS/SMB/etc. Too much for the SD card to handle.
b. In order to make it learn the network access the card is inserted
into the SD card slot of a PC and gets told the log-on data by the user.

The user can't talk to the card at the camera end.
c. Card is now a shared drive just like other PCs on the WLAN can be if
the respective permissions are set.

Again, see answer to a.

--------------- slightly OT -------------
What i really want is a wireless µSD card. It would be difficult to
do it with 802.11, with all the configuration issues. However, it is
doable with 802.15.4 PFD. It would be slower than WiFi, but can
transfer in background with transparant write-through cache. The card
should be configurable as 2G, 8G, 16G, 64G or 256G virtual flash,
mapped to a virtual drive on the server. Each card should have a
unique 64 bits hardware address.

Why should it have to know? The network part can be completely
autonomous except that you'll get a failed transfer if you access a
photo where the user happens to delete it while in transfer. Or maybe
even while the SD card is accessed at all. This would be ok.

Yes, DHCP/NFS/SMB/etc. Too much for the SD card to handle.

Why? Eye-Fi seems to work fine except that they chose to force a path
via their own web server. For whatever reason.

He doesn't have to. He'd simply remove the card from the camera and
insert it into his PC for entering such information. Then move the card
back into the camera.

Again, see answer to a.

I don't see an obstacle there, especially when considering that
companies have done it albeit with IMHO suboptimal decisions as to
access rights and paths.

I am not too familiar with that protocol and not with uSD. But regarding
cameras even a slow Bluetooth transfer would be fine. And probably even
preferred because it usually is less hassle with configuration and all.
Transfer speed is a lesser concern because the user can do something
else on the computer while the transfer happens, have dinner, fianlly
fix that leaky faucet, etc.

Well, they are cutting corners with DHCP and whatever protocols they
are using, and hiding it with their propertary server. Standard DHCP/
NFS/SMB requires lot of resources, that's why nobody is doing it yet.
It is doable, but lots of resources.
He doesn't have to. He'd simply remove the card from the camera and
insert it into his PC for entering such information. Then move the card
back into the camera.

Then you require another SDIO device for the PC, not just SD memory
card. It's cheating, but i guess it's OK.

Most smartphones come with µSD and full size SD adapters are cheap and
everywhere. I want it on my phone, but with the phone's file system
on my local Linux server. 802.15.4 is standard at 256K bit/sec, but
can go up to 1M non-standard. With a PFD (partial function device)
and unique 64 bits address, all configurations can be done at the
coordinator side. I guess this is cheating as well, while requiring a
coordinator. A PFD device can be implemented with 16K to 32K flash.
802.11 probably need 128K to 256K flash.

Haven't tested the thing, but I suspect they mean a web server resident
on the camera, not something on the wider Internet.

Don't know about Eye-Fi. The PQI clone (but with removable storage)
is a web server at 1XX.2XX.1.1 (can't remember the exact number, but
de facto router gateway address). It's the worst address they can
think of. Namely, you shutdown your internet router to use the
camera, or move your router address.

You can always build a dual radio server to reroute or port forward
the data. However, this is another case of the manufacturer telling
the users what they want the users to have, rather than what the users
want. Eventually, some other manufacturers will get it right and blow
off Eye-Fi and PQI.

It's their server and you must have a working Internet connection at
least every time you change the settings. I won't buy.

There's been lots of conjecture. Has anyone ACTUALLY used one of these
and can give actual facts?

I played with mine and convinced myself that I could configure it
manually using their dedicated card reader
and make it work on my LAN with no requirement for any outside server.
But I can't actually confirm it.

I doubt they knew what they were doing.

Sounds like a complaint to FleBay is in order.

The vendor stopped replying to my messages so I made a complaint. Ebay
initiated the process and supposedly a refund was being processed,
although they said they were crediting my PayPal account. I used a
credit card for this, so I expect it to be put back on the card. Before
that happened, I got a notice that the refund "check" did not clear the
bank and they are "reprocessing" it. I'm tired of waiting and will
initiate a credit card chargeback tomorrow. It has been nearly a month
since I ordered the thing!

I think it's best to start with the CC chargeback.. it would probably
get their attention.

Perhaps they are waiting for you to drive somewhere and "pick-it-up"?

Many Nikon's have the ability to be controlled remotely.
I believe this includes not only shutter control, etc.., but also the ability to transfer the files automatically to the PC (or in some cases, movies real time).

I've not had the need, so I've never confirmed or tried this out.
I have the D-800 and a D-90.

But I assume you still to connect that USB cable first. That's what I
wanted to get rid of.

There's a professional Nikon wireless adapter, not crazy expensive,
but not very cheap.. about $800 IIRC. You frequently see them in
tourist attractions (eg. get a photo with the Stanley Cup).

Also one of the cameras (3200?) has a really cheap wireless adapter
(<$100), but IIRC it only works with that camera.

With the frequency I use my camera $800 for just an adapter is obscenely
expensive :)

One of the discount stores here offered a small Samsung digital camera
right after my first post in this thread. Grand total $100, has wireless
download into the PC. Finally a manufacturer figured it out. I just
wonder what took them so long.
