Hello this is the shema of my circuit , i'lm using 3 SHF485P  with 2 rechargeable batteries 1.2 V = 2.4V.
I also use  3 resistors 18 Ohm as suggested  here :

When i put on , my eyes see (when in TOTAL darkness) the 3 red points.
This is ok.

But when using my numerical photo device, i see only small purple (violet) lights :

In comparison, with my TV remote i see much much brighter violet light :

This is this a photo of the led SFH485P:

I know it is not a problem of batteries as i used batteries i filled up (reloaded ? sorry for my english) yesterday evening.


I am really surprised as when i see pictures (not even in the dark)  like this one , i clearly see my system do not light enough.

Does it work?

If you can see the three leds from within the Freetrack software then none of these things matter.

There is nothing wrong with your setup.
Spot from my RC is also 5-6x larger then from 485LED. Remember that you have to use RC from much greater distance.
Also you took last picture from the angle. From that angle you can see about 1/3 of radiation from led. And it is still bright enough for successful tracking.

You are both right.
I tried freetrack V2 and i can see the dot moving.

Thank for your answer.

Now i'm trying to get evrything working with IL2 1946.
It is pretty hard to make the head moving with a VX3000.
I will read in the forum everything about VX3000 setup.

Right now without removing the Ir filter i have either
20 FPS and  1 Jitter  (interior mode)

or

25 FPS   and 6 to 7 jiter (in exterior mode).

Thanks to enable button and the flash light trick, i have now 29-30fps and 0-2 jitter.
I must add that i tried to find right settings for whole afternoon and as the sun was going down some settings went wrong to get the 30 FPS.
So when i understood this i used a white Tshirt and a flash light to emulate full sun.

I'm using VX3000, no IR removed and no floppydisc on lens.
If i  use floppy disc to filter ambiant light then i can not get 30fps.


i tried some settings for curve and evrything, the game IL2 was not nice : as if vertical synchro was off.

I went back to freetrack software and chnaged of setting for il2 1946 profile (which is named 1945 in profile list) and now the game is ok to play.

Thanks for all who helped me to buy all pieces and find the apropritate ones , the plans in easy building system  and for the advises here.
