Just bought to day 3 white ir leds, 1 resistor , and a 4 1.5v batteries holder.

In the shop they told me i could connect the 3 leds with only one resistor, question is how many betteries do i need, they said 4 of 1,5 v.

the resistor has 1 yellow stripe on top, then 1 purple stripe, 1 black stripe and in the end 1 light brown stripe.

I´ll put the leds on a cap, but i dont know wich distance to separate each led.

Take a look at the manual, but as far as I remember, you can tell the software the distance between the leds, so you don't have to worry about being very accurate in the construction.

Well, if i got that color code right, the resistor should is 47 Ohms, which is fine. If the LEDs are connected serially, and so are the batteries, everything should work fine.
Just to make things clear - by getting no light do you mean that you don't see any light when looking at LEDs, or no light when looking at them trough the camera? The infrared light is invisible to human eye, so without using a camera you won't be able to tell if the LEDs are working.

If you get no light when looking at LEDs trough the camera, examine the battery holder to make sure that batteries are connected serially, not paralell.

so if the [] symbol is a battery, you'll need them connected like this:

---[]---[]---[]---

not like this:


    |---[]---|
    |           |
---|---[]---|---
    |           |
    |---[]---|

Now i have red leds working, ill connect them to a power suply so my questionns are:

1- 3 leds and i resistor connected, how many volts should i use in power supply it can go to 12 v.

2- I bought the Trust wb 1400 t, it said on the site it could provide 30 frames, but in freetrack i only get 11 :(.

3. what is the jitter.

And since i dont have ir leds, should i remove the filter inside the cam ?

thanks

i don´t know what else to do , cant get more than 11 frames on freetrack, i change all settings and frames still the same.

This is very hard to work at 100% i bought the trust camera that  on site says it gives 30 fps

On GTLegends game it sucks, gets a abnormal turning face response.

I need to know if anyone has a workin 3 point cap with no ir leds on, cause i dont know what to do with all this, i thought it could be usefull in game but at this point it´s unplayable.
