i have purchased a PS3 eye camera with old style lens ( good one with removable IR filter) and 5mm 940nm wavelength TSAL6400 model IR LED lights. Do i have to use sandpaper to clean up the plastic layer of the LEDs or not at all ? Thanks

I didn’t need to but used SFH485P LEDs which may differ from yours. Whilst I wouldn’t advise using FreeTrack software (it’s old and hasn’t been updated for several years), there’s a lot of good hardware information on theIf site: http://www.free-track.net/english/. I would recommend FaceTrackNoIR or Opentrack (my personal favourite).

Not to clean up, you need to make the LED more scattered, so the cam can see it at more angle, by sand it, or as I did, warp it with a thin layer of paper tissue...

do these systems work? Is it usable or it glitches being diy stuff?

Definitely - my experience is that it works just as well as TrackIR. If you have a suitable webcam you can have a basic working setup free! The simplest way to try head tracking is to download Opentrack and print out a small Aruco target on some card and attach it to a hat. Although it uses a racing sim for the demonstration, there's a good video about using an Aruco tracker here: https://www.youtube.com/watch?v=ajoUzwe1bT0 - you don't need the target to be as big as the one he starts off using in the video. Using an Aruco tracker works well but it's not quite as precise as using an LED clip for tracking. If you have any soldering skills you can produce a suitable LED source for very little money.

Even if you're not a DIY person, you can buy suitable hardware ready made from the likes of Delan Engineering or Tackhat who can supply a full working setup (complete with a webcam and an LED tacking source) for less than one third of the price of the equivalent TrackIR setup.
