how to record IR from my remote ( from my n900 )
 

hi :D
anyone know how to record ir signal from remote to n900 i dont want to use any laptop in that << hahaha :eek:

i saw video to record with laptop and its long :rolleyes:
i want any way to record the signal with n900 so i can make my own remote :o

and ty :)

The n900 has only a IR Transmitter, not a Receiver.

It isn't clear that recording IR with the camera is impossible.
At best it's going to take moderately significant effort to develop the software to do this.
(place IR remote against camera, press button, observe 'barcode'.)

The back camera does seem somewhat sensitive to IR, or at leas I can see my remotes emitter light up if its pointing directly at the lense. (cant see it with my own eyes) Would be nice to have that sort of recording built into Irreco or similar.

hmm, interesting. Need to work out if the camera framerate is high enough to detect all the transitions in the IR signal.

AFAIK, IR emisors work on something around 40khz so I doubt a 25 FPS cam could read it correctly.

The 40kHz is a modulation frequency isn't it, like an AM signal? The rate of the data being sent is lower than that, but still too high for the camera to detect.

At ~30fps, each frame lasts something like 33ms (ignoring integration and reading times), and the bit length (in time) for e.g. a Sony remote control is of the order of 2* 600µS.

So no chance anyway :)

it is said there is receiver as well?

Nice link.

so you cant receive files via ir? i dont that is true.
