Make your own TRACKIR
« on: Dec 15, 2015, 06:58 PM »
Alright so if I can do this any of you can do this....cost me maybe 30 bucks....and thats Canadian so maybe 6.50USD and you have your own bad ass poor man's track IR

here's a couple pics of my Frankenstein setup

I decided not to run the wires neatly away until I tested it to make sure its all good to go but everything seems to work great so I'll throw a few small zip ties on to tighten everything up.

works like a charm

Parts List:
1-AA battery box with lead
3- 5mm IR LED's
-wire and solder gun or wire glue to connect it all up
-plastic handle from a small pail used as my improvised bracket cut to size
1-Large snap style paper clip to attach the thing to my headset
-a few zip ties
1-PS3 EYE webcam with removed internal IR filter
-a bit of super glue













Here is a 3d print file that I will be getting done in the near future which will make for a nice finish design

Interesting.  Doesn't the real TrackIR simply uses reflective stickers on the user, not IR LEDs?  I guess passive user doesn't require power, but transmit does seem more robust over reflect... Still, even though it's just a double AA battery can't you feel the weight over there?

Hey Luke,
To answer your questions:
Track IR official provides there customers with the option of going with there reflective hat setup or spending a bit more money (40 USD) and buying there Track Clip which works exactly the same as the setup I am using. Major pro with the tack clip is that you dont need to worry as much about natural light interference on your reflective tape and buy using powered IR LED's the camera can more easily follow the LED's then the stickers. Users say both systems work great in reviews though, I just decided to go with the powered clip so I dont have to wear a hat when I game.

As for the weight, its unnoticeable as the single AA battery weighs as much as the whole unit I built. Together clipped on your headset you dont notice it at all. Also I prefer not to have another cord running from my headset to my PC as the track clip pro is powered using USB. You can also make that same setup and have your own USB powered set but I just preferred to have it battery for now and change the battery out when needed. Will buy a set of rechargeable now that I know it all works.

Keep in mind you can build it how ever you want. The article here from maximumpc.com uses a few empty BIC pen's as the clip and with some LED's hot glued and wired in, your set. The article gives good info on all your options and links to other sites that give you more detail on dimensions of the clip and types of webcam's you can use. I went with the PS3 EYE as its regarded as one of the best to use for this setup.

Like I said I built this for around 30 bucks including the webcam. I figured I had nothing to lose if it didn't work and I'd probably learn something from doing it anyways. its not very difficult to do.

Alright so my first prototype head tracker clip did the job but was a bit flimsy do to the design and super glue that was crap.

Anyways I'm lucky enough to know someone with a 3d printer and I found the 3d print scematic on thingiverse which is free so I sent him the file and he sent me back the 3d printed clip which is done in two halves so all you have to do is run your wires and LED's and glue the two pieces together.

I kept the same battery pack that I had before which is a bit annoying as it does not have a on/off switch so i need to pop the battery out after each use, but it works fine.
Other then that for mounting it to the headset and got rid of the paper clip assembly which was held together by glue and went for two sided velcro. I was sceptical at first, as I didnt think it would have enough holding power when it connects to the side of the headset but it holds there no problem.
Overall I can tell that these new LED's are much better then the first design. They have a wider field of light array which makes it easier for the camera to track at high turning angles. So far I'm impressed and the new 3d printed design is really nice and simple.
Here's some updated photos....if anyone is interested in building this setup...let me know and I can chat with ya on TS on some of the things to watch out for with either the camera or track clip.

It is stronger for sure being a better material and design, but its also lighter then my first design setup which I guess is why my small piece of two sided velcro can hold it to the side of my headset as well as it does.

I just bought a Duracell rechargeable kit from costco which will provide longer run time without the need to replace batteries.

P.S To anybody who may be interested in having a head tracking unit but feels like the above mentioned is a littl more involved then you would like to get into, I have found a few online companies that offer a pre-built trackclip and ps3 camera ready and set to go.
Here are a few links I have found
