Did you mean andy@zonex.com?

Maybe it's interesting to share ideas because I'm dealing with same problems (cable availability, running on battery).

Re: Micro GPS for Nikon D2X D2HS D200 Project

That's pretty slick. Perhaps it would be better to start off with a bluetooth adapter so that you can connect the Nikon to one of many bluetooth GPS systems out there. The benifit of an always on GPS is that you don't have to worry about start up time of the GPS. The GPS-10 is supposed to have a battery life of eight hours. I usually place it in one of my upper vest pockets. Works like a charm on my Palm TX.

Thanks

Re: Micro GPS for Nikon D2X D2HS D200 Project

Very nice. Looks like a much better solution than anything else going.

You could mount a flash shoe on top of the box, unless it needs to be clear for reception. A flash shoe with the contacts would be even better.

Too bad Nikon used such low precision for the storage of GPS data. IIRC it is only good for something like a radius of 70 ft. (or was that dia.?).

Regarding wireless, it would be cool to have a wireless sender/receiver on the 10 pin and a box with GPS, remote release, and exposure timer for sequene and/or time exposures.

Re: 10 pin output specs

This 10-pin connector is unique Nikon connector or is it used somewhere else?

What does this thing use for?
To find the road?

It stores the exact location the photo was taken in the meta-data of the photo. Several imaging databases will even show you a map of the location of your images.

Re: Micro GPS for Nikon D2X D2HS D200 Project

I think that this is not the best way to implement it.

The GPS needs to be powered all the time. I don't want to carry extra battery packs just for the GPS.
And switching it on an wait for more than 2 seconds is also frustrating.

I built a prototype of Bluetooth connector to a GPS device you can carry in your pocket.

Sure, it is more expensive than a single GPS receiver, but more convenient.

The PCB for this device will be 0.8 by 1 inch. The cheapest form to produce will be on a PCB with multiple PCB's on it.
Anybody interested in such project?

Cheers
Roland

A similar product already in maket

A similar product already in maket and will be available on mid of June 2006.

too expensive for what's offered (nt)

unique

Unfortunately only Nikon is using the connector.

At USD398 + USD45 Shipping, Yes ! (nt)

A little too expensive.

Can get a Garmin foretrex 101 for much less.

Re: unique 10 Pin cable source

I bought 3 of these wired Nikon remote shutter releases just to get the cable with the 10 pin connectors. Search ebay for "Nikon MC-30" and take a look at the Adidt product. For 10 bucks it works!!

I used mine to make cables for my pocket wizards at a fraction of the cost of a PW cable.

They are push on only and don't have the screw collar, but they work at a great price.

Re: Micro GPS for Nikon D2X D2HS D200 Project

Roland,

I'm very interested in the bluetooth interface for my D200 because I already own a Bluetooth module (SirfstarIII).

Can you please give me more info? I tried to understand the forum message, but German language is very difficult (expecially for an italian native).

I also think that the best way to manage a GPS directly connected to the camera (the original project of this thread) is to control the module and its power thru a small microcontroller, infact in this way you can control the standby mode of the module and giving it the right amount of power.

I usually work with the Microchip series, so I can contribute on this way if this helps.
Ciao, Viamar from Rome

Hi Steve,

do the Adidt cables have all 10 wires attached? or at a minimum do they have all 10 pins in the socket?

forget Adidt

Not only are there only 4 wires in it, the mechanical quality of the release botton is not good. Well, okay for the money and it works for what it is intended for - but useless for GPS.

High Andy,

There are ten pins - however the plug isn't intended to beopened. I made it anyway, at the back side/cable side of the plug are only the four pins that are used.

I thought you prefer the bluetooth solution?!

A PIC microcontroller is not very helpful for directly connected GPS receiver. You can't really save energy. Either you let it receive the GPS signal - or you don't. It might be only optimized, so giving a certain timeout to power off if the camera's metering system has been not on for a certain time.

Another idea would be to save the last position the GPS receiver got and transmit this position to the camera till the GPS receiver has a fix again. But if your last use of the GPS receiver was hundreds of miles away it probably is no a good solution too...

Werner,

Are you standing right behind me?

When I was reading Viamar's note I said the exact same thing to myself. Except I was thinking you could use the PIC to hold the location for a short time. So if you went into a house or a cave (where I live) you could use the same location.

you could use the low power pic to turn-on the GPS every 10 minutes oto get a position fix update -- could save power, but give a close GPS location.

For a short time could make sense - depending on how precisely the user needs the position.

GPS location.

Well, that might already get too complicated.
What if you are just inside at this moment?

There are now different suggestions:
(1) directly connected GPS receiver, maybe with saved position logic
(2) wireless connected GPS by a propritary solution (your plans?)
(3) wireless connected GPS by bluetooth (Roland's way)
