thanks for answers everybody.
Why buy a homemade headtracking device when you can build one yourself?
Trackhat, delanclip, etc. are nothing more than glorified homemade headtracking devices.
Don't be lazy or afraid, building a good IR headtracker is easy and cheap, consider it a little summer project. It'll be fun to build, you'll learn stuff and will also save money in the process.
I built my own IR headtracker for under 20 bucks and it works like a charm, I'll be glad to give you some pointers if you like.
another problem is that i have no idea how to use Resistors (i dont know which one i need)
i will try anyway. thanks
Opentrack won't give you trouble, it works like a charm with DCS
Resistor choice will depend on power source, kind of circuit (parallel or series), IR LED required voltage, etc.
Use this calculator to know the optimal resistor for your circuit (series circuit schematics included): http://ledcalc.com/#calc
To give you an example, my headtracker circuit (series) is as follows:
- USB cable as power source (5 volts)
- 3x IR LEDs (1.4 voltage drop each)
- 27 Ohm 1/8 resistor (circuit runs at around 30mA, which is quite ok)
-Thin electrical wires (they are more efficient)
If you are afraid of "designing" your own circuit, just copy mine, it'll work.
Use IR LEDs and a USB cable as power source, you won't regret it.
Building the circuit in series is super easy, just connect the USB ground wire ( - ) to one end of the circuit and the 5v wire ( + ) to the other end... the rest of components are placed in between those (one after the other, resistor comes before the LEDs).
Just follow the schematics shown in the resistor calculator (usb cable instead of battery, though)
As for the IR LEDs, they have a + and - side (anode and cathode) which are easily identifiable.
The cathode (-) is the one that contains the "anvil", semi-conductor die and reflective cavity, in other words, it's the big thingy inside the LED that produces the light.
The smaller thingy inside the LED (post) is the anode (+).
Just check this image for reference: http://www.humiseal.com/wp-content/uploads/2013/06/led-throughhole.jpg
As for the headtracker model type, I recommend clip rather than cap, easier to assemble
and you can just attach it to your headphones using a plastic clip (it's what I use).
It also tracks movements better in my experience.
Here you can see the measurements of my clip: https://i.imgur.com/gnjwuQw.jpg
I use a cheap PSEye camera with a light filter (a piece of floppy disk tape) for tracking, it tracks at 75Hz, which is great.
I definitely recommend it for this purpose (if you have a camera that can track at even higher refresh rates, then go for it).
I use Opentrack 2.3.10, it works like a charm with DCS.
That's about all you need to build your own IR headtracker, so get busy already, ^^
where you got your ps3 camera from?
They are no longer manufactured I think, but you can still get them online.
