I think you can get replacement outer (dome shaped) lenes for the gopro housing...if so a guy wouldn't have to use the gopro housing at all...he could set all the components up inside a pelican/otter/S3 etc.

gary must have made a special program for you hey? Any plans on showing us how you connected to the SS2 with that USB? Which wires go where? :pleeze


I usually build the motion detector separate from the camera so the small waterproof GoPro housing was perfect for my application. I'll draw it up tonight and post. No special program for the picaxe necessary. Just have to set the turn on pulse to 1 second and the turn off pulse to 5 seconds in the picaxe script.

Ok, here's how to do it.

Out of the 30 pins on the GoPro bus, there is not one to click the shutter. Go figure. But the GoPro does have a mode that you can set that automatically starts either taking one pic, go into the time lapse mode or video mode when power is applied. In this application I set the GoPro to the time lapse mode. When motion is detected by the SSII power is applied to the GoPro. It instantly goes into the time lapse mode and takes a pic every two seconds for one minute after motion is last detected.

Here is a nice cheat sheet for the GoPro setup.

Image

My original setup had the GoPro in a box with the SSII. It worked ok but for my application I usually like the motion sensor to be separate from the camera so I can use it for other camera setups or easily swap between the different GoPro models. Plus the GoPro already has a nice waterproof housing. My next mod to this setup will be to install the motion detector in an empty GoPro housing and camo both. One other thing I will do in the next iteration is install a photo transistor in the circuit to turn off the setup at night. Or turn it on at night and off for daytime when using the IR modded GoPro.

Parts needed:
1 - GoPro Hero HD or Hero 2
1 - Bus break out board from here. http://www.chargeconverter.com/store/index.php?route=product/product&product_id=151
1 - PN2222 NPN Transistor
1 - 10K Resistor
1 - Snapshot Sniper SSII controller or other programmable controller
1 - SPST Switch
1 - Enclosure - I used a Radio Shack enclosure but you can use whatever you want.
1 - A few inches of wire

I used the bus breakout board for ease of experimentation. My final version will have the transistor and resistor in the motion detector box and only have a connector for the bus.

Here is the schematic and a couple pics.

I had never used anything with a Picaxe controller so after a little research I built the circuit below to adjust the timing of the turn on - turn off pulse.

That is super. I imagine a number of us will be trying this. Thanks for the trouble of sharing it.

No trouble. Happy to share. I look forward to seeing what the group comes up with.

Thanks so much for sharing all that info! Its pretty exciting when something new like this comes out...especially with such detailed info to get started with.

I've already got the GoPro HD, so I'll be doing one for sure!

Wow TRLcam, excellent info. I'm not much of a video guy, but you definitely have me watching.
