You quoted on a project recently that was detailed as follows.
I need the same thing and after doing some initial research and searching I came across this ad in Google!!!
"I would like someone to design some hardware and write the code for small Arduino based GPS, 3D compass logger (on to SD card). The device also needs to act as a trigger (and intervalometer) for a camera.
The device will be attached to a camera. Every 5 seconds it will trigger the camera (close a connection for 0.5 sec) as it records onto an SD card the following values from the GPS and 3D compass.
* Any extra data a bonus
The idea is that I can use the data stored on the SD card to then geotag the images on the camera with location, and viewing bearing, pitch and roll.
No need for a casing.
The UI is negotiable. The only thing I need is to be able to start and stop it and know if it is running. Any extra UI a bonus.
Please include in your bid the cost of postage and materials to post the final working hardware to me in Australia.
Feel free to use OpenSource, as this hardware will be part of a larger opensource project.
Mine varies a little though, as I need to control 8 cameras. Each camera holds its own SD card, so I can store direct to the camera, or ideally, to a storage device.
I have 12v 10a power option. No case required.
