I had an xbox 360 camera (still have) that I was using for the blob tracking on my multi-touch table but I noticed that the FPS on it where not good enough to capture the movement on a software project im working on, a keyboard. It would just miss half the letters typed.
So I saw that the HD PS3 Eye camera has twice the image of the camera, and 3 times the FPS. That and it is only $25 off ebay used. SO I go it.
I just finished ripping it apart, I had to remove the IR filter that are on all webcams to block out the infrared light, and added a visible light filter (3 layers of exposed black camera film) so now it only sees IR.
Im not sure if this will fix the issues at hand, but im sure it is a good step.
After soldering that chip the other day, I tried it with a 28pin. Practice makes perfect (well, better at least) because it was so much easier. No issues, and Im pretty confident that I did not over heat the chip either. Im waiting on a 3pin resonator for the circuit before I know for sure. Originally I bought all these proximity/ touch sensors to make a keyboard out of, but I decided to go down a different route, and just make the keyboard completely out of software. Hence the new camera.
