Letum IR 2.0: "Return of the Geek Antlers"

Letum · 05-01-09, 07:49 AM

Many moons ago I wanted to buy a TrackIR system, however I wasn't going
to pay £150 for one when I could build one my self.
The result was Letum IR 1.0:

It was a little basic. Only 2 degrees of freedom and it took a chunk out of
my CPU power.

Now I have upgraded to LetumIR 2.0 with 6DOF and networked image processing!

The software this time is FREETRACK.
the USB camera has had it's IR filter removed (easy) and a new visible light
filter put in (made from the inside of an old 3.5 floppy).
The camera takes ~5% of my CPU, so I have it running on a laptop. It sends
the TIR data to my PC via a program called GlovePIE.

Plans:
Make a mount for the side of my head. Not so easy as when I turn my head
tends to block out the LEDs. It works great on top anyway.
Make it more sturdy. If I ever drop my headphones it will fall off at the moment.

It works great! IL2 and other games runs in 6DOF mode like a dream..
If anyone wants help building their own, just ask.

Here is the software picking it up:
3 almost perfect dots.
It is accurate enough to use as a mouse for net browsing.

Shame it can't give me a shave as well. Must attach razors to it some day.
Note the extreme use of electrical tape.

I was experimenting with making my own trackir thingy aswell and was working on a similar setup, though my led placement was diferent. that being said, your stash overwhelms my ability to take you seriously

I like seeing ingenuity beat out the over priced guys.

Very clever! You do take it off when your friends arrive
