Hi All,
I have recently built a GPS receiver which attaches to my camera (Nikon D200). When locked on, the co-ordanates are embedded in the image file.
This all works well - except...
When in built up areas, the lock is lost and as such, No info provided in image. I would like to kill two birds with one stone here.
I have found a small, compact logger from Sparkfun.com which will log to a SD card and can use this. However, I would like to add the functionality that should the lock be lost, it should continuously send the last known co-ordinates to the camera.
How might I go about doing this?
Some constraints are: - Size - I am limited to space as I would rather not have a huge box stuck to the top of the camera - Power - Already, the GPS, MAX232 and the fact that the camera does not go into standby when GPS available, drains the camera batteries rather quickly.
Any pointers would be appreciated.
TIA
Cheers, Crispin
