If you want to take aerial video with your GoPro camera, the DJI Phantom quadcopter, which we’ve featured here, might come to mind. If you don’t have $500 to spend (or more if you don’t own a GoPro), you might be looking for another cheaper option.
Update 4/22/2014: After a helpful conversation on G+ with Trevor, I realize this camera may actually be the more expensive (around $60) 808 #16 V3 camera (Amazon) with a wide angle “D” lens. Or maybe another 808 camera with a “D” lens. For more (much, much more) info on the versions of this keychain camera, check out this article by Chuck Lohr. Thanks Trevor!
The video, as seen after the “read more,” from this camera is actually pretty good considering the source, but it’s really no competition for a proper aerial filming platform.
On the other hand, you could simply buy one with a camera already built in, as is the case with the “C” version. It’s about the same price, but if you already have a little quadcopter, the keychain camera gives you the option. Also, I suppose the DIY version could be pointed down, if that suits the situation.
Below is a sample video of the H107 C flying around. Like the DIY version, the video’s not great, but you could probably pull a few decent still frames out of it.
If you haven’t been convinced that you need to get one of these little quadcopters, be sure to check out this post. In it I create some spectacular light graffiti using a H107 L model with a sparkler attached to the bottom!
