My third clip.
First one was made of a bottle screw cap and pen pipes with wires going through them to the leds on the tips. The source was an usb cable (that broke a lot of times). Later I did another one. Instead of pen pipes I used a hard wire, that helped connecting the leds, powered by a cellphone battery. It had too much weight, not comfortable to use, headset moving when I move.  Now its time for a reflexive one  Made of laser cut 5mm transparent acrylic with circles covered with that reflexive ribbon used on uniforms, bags, etc.  Webcam uses 3mm black acrylic, where I placed 10 IR leds powered by the 5V from the cam's usb cable. I used a switch to turn it on and off and a green led to indicate state, as human eye can't see the leds.   Here in Brazil we call this "gambiarra" Worked very well, almost no weight on the headset, no wires, no battery discharge, no problems   Good gaming! |

I'm glad that you are enthousiast about the Fimo clay diffusors. Here's the link to my topic (from 2010) Click  |

Hi,
I found a link to Your topic and I decided to try. They work great not only to extend an viewing angle but also to get rid of some light distortion and unwanted reflections. Your idea with FIMO was brilliant Congrats and thanks |

As promissed a long time ago; the pictures of my finished tracking device mounted on the headphones with a custom scheme paint. Works like charm.
   Regards. |

Hat setup, 3 cheap IR (photo was made before filling the LEDs), series circuit with classic 9V battery (with 270 Ohm summed resistors and switch on battery box) Logilink 30FPS cheap (around 9 EU) webcam, IR filter removed, IR-pass filter mounted (2 polarizing filters from 3D passive glasses, mounted in the right position to block all visible light), 640x480@30FPS. Works like a charm  Made a FRAPS video also with some GTR Evo gameplay (in 3D stereoscopic) |

I finally made my own!
The emitter is built from brass tubing, a small plastic container, and IR leds from radioshack. It attaches to my headset with some velcro-like stuff.  It's powered via the attached battery pack. Originally it was attached on a short cable, and stuck on to my headphones with the velcro, but it was too heavy, so now it hangs around my neck on a lanyard.  I use a playstation eye with IR filter removed and bandpass filter installed. (floppy disk film) |

My 1st attempt at a reflective clip. Went the reflective route because I needed something more elegant and lightweight with minimum parts and wiring. Cost about £10 in parts off the internet and the use of an old pair of chipped lightweight rimless glasses, example in pic. The yellow high reflective tape worked better than expected using an A4Tech infrared cam as recommended at this webite, cost approx. £20. Accuracy and smoothness of movement again better than I'd expected using only a 3 point reflective model; with a reflective model though, you must be prepared to keep your surrounding room environment as dim as you can for it to work effectively.
