(Announce) ledpulse (Sound Reactive Leds for your n900)
 

This app can make your n900's led being sound reactive :D
You can choose the colour of the notification led and which keyboard leds to blink like the sound! You can choose from 3 sources(Monitor/Bluetooth/Microphone)!

Here is a small video of it in action!

Credits goes to nicolai and you can find the program on extras-devel

No one is interested about this??

Re: Nokia N900 Sound Reactive Led
 

Not personally. You need someone to hack VU Meter and add led output. It does what you want but just in graph form.

Hahaha not actually the answer that I was waiting :P

Re: Nokia N900 Sound Reactive Led
 

Afaik the led on the N900 is controlled by MCE, which settings can only be applyd by restarting MCE itself. This takes some time and can only be done a couple of times every 5 minutes or so. Apart from that, a faulty mce.ini file, where these setting are, can seriously mess up your N900 usability ( read; brick your device)
So in my opinion you'll have to create a new system or program to control the led, and i doubt that is possible... :(

quick n dirty python script.
(definitely a battery killer)
run as root.

Re: Nokia N900 Sound Reactive Led
 

Thanks for your time! Is there any chance to make it work with the keyboard leds as well?? Do I need to change this:
led_r = open('/sys/class/leds/lp5523:r/brightness','w',1)
to this:
led_r = open('/sys/class/leds/lp5523:kb1/brightness','w',1)
for example?

One more think I want to say is that it captures the sound of the mic as well... What I mean is that when I talk for example it lights up? Is there any way to remove that?
Why do you think that it is a battery killer? How much energy could a led need? Thanks again :D

Re: Nokia N900 Sound Reactive Led
 

Erm, isn't that what you wanted from very beginning?

As for battery, it's not only about LED's - it's about constantly probing sound input, waking CPU, etc. You're, probably, going to have ~10x worse standby battery life, if using it all the time.

Re: Nokia N900 Sound Reactive Led
 

Well I wanted to caprtures only the sound of the music that was playing from the player, not the sounds from the mic...
For the battery I understant what you are saying but I won't probably use it all the time :)

Re: Nokia N900 Sound Reactive Led
 

Replace with to capture speaker output.

Also see my own Ironcope (source) to show how a similar thing can be done in C. If done properly (e.g. recognizing when there is nothing to capture) it does not kill battery that much.
