It is connected to USB 5v
Resistor parametres depend on diodes..
The connection scheme - page 13 manual "doc_led"
Clip cut out by means of "Dremel"

It is possible to use this tool

Hi,

Thanks for posting those pictures.

I'm having trouble finding the "page 13 manual "doc_led".

I really like your design, and would like to copy it.  If that's ok?  Could you post more pics or even a tutorial of how you designed and built it?

However if it cost 30 US dollars for the materials, I'd just as soon purchase a TrackClip Pro already built and not have the hassle:)


Thanks again!

No more SFH485P (no more in stock available), but these one seems very powerful (see listing under) IR --> 375mW/sr @ 250mA.I use USB cable connected to a box with 4 AA battery with USB connector.

..I then used WiiMote system for FPS  :lol:

Wiimote is used and mounted on the wall with its battery charger with unlimited power supply on my Wiimote.

Material: (Conrad is online reseller)

- 1x cintre métallique (nearest Laundry  ;D )
- 1x Wii Remote Twin Charger SL-3403-SWT (eBay, Ricardo.ch, etc)
- 1x Conrad BT USB Stick Micro (Bluesoleil v5.4.277.0) n°971999-62 (Conrad)
- 3x Trimmer 1W 50 ohms n°425036-62 (Conrad)
- 1x Boîtier support 4 piles AA USB n°079694-62 (Conrad)
- 2x 1m câble AWG 0.25mm2 noir et rouge
- 3x OSRAM SFH487P  n°631312 (Distrelec)

..and so many tools....

I have not made my 3 point LED cap yet but whilst I am waiting for parts I have been experimenting with how to mount the Wiimote on my TV. Here is my simple solution, hope it is useful to someone!

This just uses a wii remote gun accessory, you can get them from ebay for a couple of pounds/dollars.

Then i used a small cable tie to secure the trigger part of the gun to the TVs cooling vents, 2 would be better (little tricky getting the other end of the tie out). The weight of the wiimote keeps it very steady but a small blob of bluetac under the barrel would make it even better. I may use velcro instead of cable ties ultimately, would be nice to remove the gun when I'm watching a move (things like that bug me).  Its also very easy to remove the wiimote from the mount if you need to use in on your wii.

If you decide to use this method please send me a PM and let me know how it has worked out for you, thanks  ^^

Hi all. Here are some "classical designs".
Newest tracker : 3 point clip,made from double copper plated electric board, usb powered, using common ir leds - sanded to become "wide angle".

3 point cap using only 1.5v to operate the leds, no resistor at all:

Hi everyone, I have designed my own freetrack headset which has no need for batteries or candles. I beleive a few people have done a similar design using reflective tape on a cap or on headphones. I found both these methods to be annoying to use. The cap makes you're head all sweaty and the headphones make you're ears sweaty too.

My design is a headpeice made out of tin foil wrapped with insulation tape and the 3 point clip design attached to the side which is made from card with reflective tape on 3 points. I took roughly half hour to make in total and works great. Here are some pictures of the headset.

The webcam I use is an A4Tech PK-333MB. It uses 6 ir led's for low light situations but you can use them by covering the sensor so you can use it with lights on. The camera picks up the reflective tape very well so you can turn the brightness and contrast right down and the headset will still be seen. I'm not sure if I've explained sufficiently so any questions then feel free to ask.

Have a nice day. :)

here is my build.

my original clip design which i used successfully for quite a while.
Posted Image
Posted Image
i found the l.e.d's were too close together and if i lifted my head too high the bottom l.e.d would cross over the center l.e.d and confuse the software so i built a new one.
Posted Image
the construction is from a 120mm fan grill i used a pair of wire cutters and cut in the necessary position to achieve the desired shape i then cut the top arc slightly shorter than the bottom one.

Posted Image
the l.e.d has been filed down until its almost at the element inside to give optimal exposure to the camera.
Posted Image
here it is attached to my headphones, the attachment is made via a bicycle light clamp which i bought from the local pound shop, no modifications to my headphones was necessary.

a close up.

my wiimote and stand
Posted Image
the wiimotes usb rechargeable battery
Posted Image
as you can see it just slots onto the stand and is constantly charged via the usb cable so no need for battery changes and remains completely standard and usable on the wii still.

as its attached to my headphones i decided to use a usb cable and so my clip plugs directly into a usb slot.

cost list

L.E.D's, Resistors, Solder, and Wire all from ebay for around £10
Wii Remote £29.99
Wii Remote USB rechargeable battery pack from Game £10
USB Bluetooth Dongle from Argos £10
Total Cost around £60

build time around 1 hour 30 minutes due to soldering and testing.

I need to make better clip but this solution works too. :D I use 6V DC adaptor and 62,5mA constant current source with LM317T.

Edit: Adaptor gives actually 8V.

Very nice setup!
You beat me to the idea of  clip with circuit board as frame with integrated constant current source.
This would be the ideal setup from a design and PC USB safety standpoint.

I'm not sure if it will work with 5V. 6V is probably minimum for 3 IR leds. It gives 4,33V on the output.

Yes you are correct about the 5 volt input.

I had mistakenly said that about the USB.
6 volts is probably approaching the minimum it will current regulate at.
What is the 6V adapter voltage at under actual operating (tracking) load conditions?

Glad to see that you incorporated the the constant current method.

Oh, I found out that my adaptor has actually 8V under load. It's cheap china adaptor. Looks like 4,5V gives 6V and current is not good in this case. Still works but not as bright as under higher voltage.
