Wire remote for GoPro Hero

Hi!

I want to control the shutter of my GoPro HD Hero 2 via the iPhone/iPod-like connector on the back. Of course, I did extensive research and found this pinout list: http://chargeconverter.com/blog/?p=71

As you can see, there is no trigger in or trigger-button-in (I hope you understand what I mean. You can see a power-button-in). All the DIY projects I found use the power-button and set the camera to auto-capture mode, so the camera starts recording when it's turned on. But that wont be suitable for my project, I cant wait 5 seconds between every photo. But, GoPro itself sells a remote to plug into this connector , and a few on the internet managed to trigger it somehow. But I can't find anything about this "better" approach.

Does anyone here have information about how to accomplish this?

Thanks!

It looks as if some of those pins are for a serial data interface, maybe there is a control protocol. Unless it's documented somwhere, the only way I can see to find what it does is to get hold of a controller that does what you want, and use a logic analyser to reverse-engineer how it works.

If the go-pro takes a remote shutter release that is triggered by infra-red, it would be a simple matter to have an arduino learn the sequence via a IR sensor and then repeat the sequence via an IR led.

If not, you could always use a servo to press the button, for example: http://www.youtube.com/watch?v=1mCgqGIGyRo&feature=topics.

Seems somebody already did this on a pic http://bikerglen.com/projects/trailview/onecam/ looks like some fiddling with the ID pins gets it working. Emulating the IR remote should also work.

Thanks!

Well, what I don't understand: There is no IR-receiver for the gopro, and I read somewhere that there is no IR protocol integrated in the firmware.

Reverse engineering would be an option, but this is actually what I want to avoid, buying those expensive things. The Servo-idea is a possibility, but you all know, it is just not "right" :D

Thanks for the link, I'll read what i can find ;)
