N900: How to turn infrared-led ON?
I'm planning to use N900 as light beacon for infrared-camera (e.g. as wiimote's sensor bar replacement). So I'm looking way to just turn infrared led on. Not transmitting any IR-codes.
I made first test with lirc and it's irsend, but it is targeted for IR-signaling, so it is not very suitable as it (maybe with very special config-file). |
Re: N900: How to turn infrared-led ON?
That little tx led is not enough to illuminate something in the dark . You better try a case mod on your N900 with a separated circuit for an ir torch . Just like that guy modded n900 case with bigger lens for camera .

I agree, the IRED is not going to illuminate much.
It is not designed for this purpose. |
Re: N900: How to turn infrared-led ON?
My opening post was too vague and general. I'm planning to use N900 as Wiimote's sensor bar. (Sensor bar is bold name for 12 infrared leds). I have used two candles, but they emits too much visible light when playing/surfing/watching on dark room. And they are not safe when there are children and animals running on the same room. Self made battery+IR-led would work but I'm not handy to make it nice looking. (I almost bought wii wireless sensor bar, but seller didn't know how often battery must be changed).
And I'm Maemo-hacker so I'm looking software solution :D ----- With lirc and endless bash loop I can blink IR-led forever. With one N900 this is enough for wiimote to work (under Ubuntu and open source driver it needs only one led), but it lags/jitters (I think it is because of blinking). I also test with two N900's side by side, but they are not blinking in same sync, so mouse cursor is continously waving/jumping left to rigth (=not usable). |

The dev of Pierogi is the man to ask about this.
Not seen him about for a while tho. |

999 is biggest it accepts. Next step would be tuning driver: http://svn.jacekowski.org/host_mode/...rc/lirc_rx51.c So far this is my best: Code:
#!/bin/bash When looking trough another N900's camera there aren't blinking at all. [EDIT] Simple modification to the driver: Code:
drivers/input/lirc/lirc_rx51.c If echo is stopped (ctrl+c) led is dimmed OFF. When infrared is in use, device can't go deep sleep states, so bash loop is not heavy addition. [/EDIT] |
Re: N900: How to turn infrared-led ON?
Can i record lightless with infrared with n900 camera ? Are infrared torches available what about a tiny infrared module on back of n900?
If this can happen then lets sue estel to put one on his mod:) |
