I would rather have it tethered...

2.4GHz is also the residence of 802.11b/g, cordless phones, microwaves, etc. With only 11 channels to choose from, I think it would rather have it tethered.

I suggest that the size will go down quite a bit when you put a production circuit board into place. Those bread boards do take a lot of room.

hi az_av8r,

would you like to share the circuit digram for translating the levels that you used.

i am about to do the same as you, and would happily share my testing results.

mail me col at loudspeaker dot org dot uk

many thanks

Re: Micro GPS for Nikon D2X D2HS D200 Project

Hello,

found this old posting of the GPS for D200. Wondering if the project is progressing and what the status is. The GPS solution is very interesting and I would like to see if I can get one... I particularly like the powering from the camera.

could you email me perhaps at ultravoxx.xx (a) gmail.com

Go for the GeoPic II - I got it recently and its great. Freeze mode is really cool.

any update on the Project?

I'm interested in a reasonably priced hardware solution of the type.

di-GPS for close to $300 is a bit too much for me especially that I do have a working software solution for georeferencing my pix based on the GPS log record.

Hello Can You write down the Wiring connection diagram for the 3,3 GPS RX TX signal level to Nikon 5V Signal Level ( The two transistors and resistors on pictures) I try to connect My 3 V TTL oput GPS to nikon without any resoult. My Camera is Nikon D300s

Can You Halp Me

Maybe try this - http://www.sparkfun.com/products/8745

They do have distributors over in Europe.

The level translator is of course a solution. Still...are you sure you connected the wires right? Your 3V output should be enough for TTL input requiring typically 2.4...2.6 Volts to detect high...just a thought

Re: Micro GPS for Nikon D2X D2HS D200 Project

Yes i try any of type ( changing Rx cabel with tx cable on Camera side) when i put the digital multimeter set to Volt mesurment on gps side i got a 2,5- 3 V on Tx Cable and 2,8-2,97 on Rx cable. My Gps is BT like Holux gslim r236 Rev B. ( in speyfication this gps reciver had RS with TTL/LEVEL oput

ther is a Cable for it to connect to PC with RS port ( Cable had a max232 level RS translator inside )
And also by SPP ( Bluetooth Serial transmition) on my laptop it works...

For me the best solution wil be the bluetooth adaptor for camera that can work with bluetooth spp reciver but the price is to hig with shepment to poland

Seems the China folks pretty much copied your ideas and made it for $150 usd (Amazon had it recently for $130.)

I bought one, it works great.

Holux 236 output TTL level but at 384,000 baud (or something like that). It cannot work with nikon because nikon requires 4800 baud. It is possible to flash the Holux GPS to 4800 baud firmware but the trouble is more than it is worth.

Re: Micro GPS for Nikon D2X D2HS D200 Project

Ok I Understud, but on BT SPP can chose baudrate and gps work with difrent Baudrate..

I think the best solution is use BT spp function but it will be to dificult to mi to homemade it.

Any one have expirience with bluetooth adapter to NIKON DSLR (for example from Ebay ?) --

Re: Micro GPS for Nikon D2X D2HS D200 Project

Hi,

I make a Bluetooth Adapter for Nikon DSLRs now (search for "foolography Unleashed" if you want to know more), but I started by making the Holux GR236 work with Nikons.

With the standard firmware, it is not possible to change the baudrate to 4800, since too many people changed the firmware via Bluetooth, and were then no longer able to connect to the device, since the built-in Bluetooth module only works with 38400 baud.
it was only possible to change it back if you had the serial, or USB cable.

So, in one of the earlier firmware updates, Holux turned off the possibility to change the firmware.

I happen to have a (current) firmware which does allow for the baudrate to be changed to 4800, and might well choose to publish that on my website soon, since I have recently discontinued my product "GeoTiger", due to lack of interest.

Many Greetings,

Oliver

How Your BT adapter paried with gps BT device ? it should be programed first ? or bt Adapter always looking BT devices with standard 000 PIN and SPP protocol ?

Re: 2011 Update

One word more : there is a lot of messages here about adapting the CMOS serial signal from a GPS like Holux Gpslim240 to the TTL input in the Nikon camera. This
is ERRONEOUS or at least UNNECESSARY !

My experience is that the Nikon input is Cmos compatible and that the 3.3V output of the GPS is able to DIRECTLY drive the camera. Thus, it is only necessary to change Baud rate of the GPS (which can be REVERSED to use Bluetooth again).

I have posted a photography on photo.net to demonstrate it
( filters-bags-tripods-accessories-forum/00YjtY).

Regards.

Re: 2011 Update

I bought a MicNova GPS for $39.99 on amazon. That's cheap! Anyone have any experience with that unit?
