In a related vein, I got a SooCoo Cube 360 camera, which looks similar to the Kodak camera, but is substantially cheaper and simpler (and probably of poorer video quality).
I tried it out this morning, and whilst it produces a tolerable image quality, mounting it looking directly up, tends to show too much of me, and not enough of the surroundings. I've seen it described as having a 190° range vertically, but I think it needs to be angled downwards, so it sees more video directly forward of the viewpoint.
You can find this (or very similar) cameras all over the place, for around £50. It's clearly not going to be as good as the Kodak one, or other much more expensive options, but it's fun to experiment with.
I'm struggling with converting it into a form that can be uploaded reliably onto YouTube. Whilst I can do this, any attempt to manipulate the file, eg trim the time, change the audio etc causes problems. Currently this means I have to upload each 10 minute file onto YouTube, and I'm then limited to whatever editing the Video Manager allows.
