FWIW, I just tried the magnetic (non-GPS) compas in my Garmin unit,
and it seems to be unaffected by any proximity to my D200.

That's interesting - and surprising. The Garmin probably has no interface output for the compass?

Maybe I should get one of this cheap electronic compasses for trying. Or I might try the better mechanical one from my scuba diving equipment (when I get another hopefully then working D200...). However the larger the unit the greater the problem to get close to the camera (where a sensor would actually be). Would be interesting where the Garmin's sensor is and if it's still working fine when it's close to the magnets of the camera's (or lens') focus motor (what I still doubt).

Re: Do you take any orders?

Andy,

I'm willing to alpha or beta test for you if/when you decide to do it.

I'll sign an NDA, etc. I'm willing to assemble parts here, too, if needed.

Tried emailing you in profile, but it doesn't work.

I’m still just
having fun with getting the unit working, playing with the
features, and getting feedback on the concept.

I think, for me as a photographer, it's most important that I can still use my external flash. The GPS is a nice feature but I can live without it. The flash is a neccessity.

Need a beta tester?

Check my qualifications. MS in Photography from Brooks, built a FM station (my own), etc.

BT not a good idea!

Although it would seem like a good idea in theory, since I have som experience using a BT GPS with PDA, I would disencourage this solution.

Main reason is the KISS principle, Keep It Simple Stupid, the camera has to be exposed to outer space (= outdoors) to make this meaningful in the first place. It would be extremely easy to reduce the size of the unit into less than half and the camery is there, the power is there and the sky is present, so solve the problem and don't invent new obstacles.

If anyone woul stick to the BT solution, I have tried a BT/RS232 dongle from "www.free2move.se" (built into the DS9), works nice, but it still needs to be powered from the camera and it would still need to sit somewhere, so why?

I would volunteer to make a PCB layout.

That's what I think too. However the aim would be to let the Bluetooth module "sit" right on the plug. That's the only way it would make sense to me.

However Roland is in Skandinvia on vacation right now and wrote that his Bluetooth solution doesn't work there. Obviously there are too many mobile phones with activated Bluetooth there?!

Scandinavian bluetooth smog?

Doubtful

BT/RS232 dongle to MC-35?

Wow, I'm very interested your BT/RS232 dongle solution. Would it be possible to connect this dongle ( http://www.free2move.se/prod_spp.shtml ?) to the MC-35 cable?

(BT is IMO still better than a GPS powered from the camera, beacuse if you switch the camera off the GPS will take longer to get a fix next time.)

cheers,

Practically it's not really better because it takes at least one second till bluetooth devices find each other and as there is the position only transmitted once a second the average time to get the position by bluetooth will be at least two seconds.

With my Sirf II receiver I manage to get the position from powering on in the same time (if location hasn't changed much and last use was within 15 minutes) - and Sirf III should be even better.

Sounds good to me. Could you elaborate on your setup?

cheers,

Warm start up for the new Sirf III type GPS units are less than 1 second.

it's hot start...

...that takes about 1 second. My Sirf II is already this fast. So there is nothing special about it.

First I have to admit that I'm not neutral but biased because I'm working on a GPS solution for quite a while myself.

Using a wired, battery powered GPS receiver is the simplest way to go (so in my opinion highly overpriced here) and not very smart - as it's not very smart to use a GPS receiver with patch antenna (so a flat one) that is according to the given dimensions obviously used in vertical direction. I believe that while using GPS it's more likely that one is shooting in landscape, so it would be better if the antenna is mounted in a horizontal position - facing to the sky for better reception.

Re: Can also go this route...

Thanks a lot. The BT solution looks good, but I don't want to share the my D200's power with the BT. Usually I bring two batteries for my D200 for one day trip. If the GPS share the battery I may need the third battery.

Re: Question ...

Hello there,

My gps isn't talking to my D2Xs camera properly. The gps icon on the camera shows up when connected to the gps, but flashes continually. The gps knows where it is (has satellites), but the camera thinks it doesn't. I'm using NMEA/4800 baud at the gps, with the MC-35 Nikon cable and a rs232/9-pin serial port wired to the gps power/data cable as per Garmin's instructions, but to no avail. If you have any solution, or know of someone who may, your help would be greatly appreciated. The gps is a Garmin 296, panel-mounted in an aircraft, which I use for aerial survey work, and the gps works very very well on it's own. Cheers.

Dave.

NMEA sentences?

Which NMEA sentences are transmitted? The cmaera needs $GPGGA and $GPRMC.
