Bluetooth or WiFi DS cards for offline use?

So have I. That's easy. It becomes much less easy when you have to share experiments in progress with people, stuff where fine resolution is needed. Under a microscope and so on. This is what I am after.

You failed to include how long it takes you to climb the pole.

That may take Jan a long time and numerous groans. Coming down the pole OTOH can be done really fast :-)

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.

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".

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.

My camera is not on a pole, or even at the pole.

Here is how to handle the pole:

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.

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.

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

The user can't talk to the card at the camera end.

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.

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.

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.

r.

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.

Monthly revenue !!

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

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.

Oh my.

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 abili ty 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.
