Here are some pictures of my hat-camera. No, this is not my original idea. I got it from other people online, and simply picked up some hardware from Home Depot that I thought would work best. Here are some photos of what I put together. I've been using the hat cam now for a couple years and it works great! It doesn't aim perfectly (it usually aims just a little too high when I am really close to something, and just a little too low when I am very far away), but it works well enough most of the time. The hat was free basically, since I had plenty of them lying around, and the hardware costed something like $3 maybe. Certainly a wise investment I'd say.
