(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

Re: Nokia N900 Sound Reactive Led
 

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.

Re: Nokia N900 Sound Reactive Led
 

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... :(

Re: Nokia N900 Sound Reactive Led
 

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.

Re: Nokia N900 Sound Reactive Led
 

Thanks javispedro it really works!
Is there any app that turn off completely the keyboard backlight? I can't find anything...
One more thing... how can I add more led to work the same way at the same time? I am trying to find it out but I can't :P

Re: Nokia N900 Sound Reactive Led
 

change thread title to announce n900 sound reactive led:)

Re: Nokia N900 Sound Reactive Led
 

well I am new to site! how am I doing this? :)

Re: Nokia N900 Sound Reactive Led
 

just use the edit post button below yor first post in this thread:)
p.s do credit the author in the body:)

Re: (Announce) Sound Reactive Led
 

Ok I changed it :)
I want to edit the file a little more but I don't understant what 'w',1 means on this line:
led_s = open('/sys/class/leds/lp5523:kb1/brightness','w',1)

Re: (Announce) Sound Reactive Led
 

open file for writing ('w') with line buffering (1).

Re: (Announce) Sound Reactive Led
 

Well I am a newbie as you can understant :P
I am trying to put more leds to act like this but I don't find the way...
Do you know how to do it?

Re: (Announce) Sound Reactive Led
 

Well you didnt credited the author in the post . It should be as the attachment it some posts below so with the title the post seems like a prank ! :D

Re: (Announce) Sound Reactive Led
 

Hi Nicolai thanks for the script,but if you find a time could you packaging these tools and put in extras-devel,by the way thanks to bill_klpd for the idea

Re: (Announce) Sound Reactive Led
 

Do you mean like this?

Re: (Announce) Sound Reactive Led
 

yup buddy thats it ! :)
later on you can update the first post with informative and useful infos:)
optionaly you can add screenshots to make the post more atractive:)
thanx to both devs for lisening :)

Re: (Announce) Sound Reactive Led
 

Post edited:)
btw it can be uploaded to the repos??it would reach more like mindeds :)

Re: (Announce) Sound Reactive Led
 

well I don't know how can this be done :P
but why not?

Re: (Announce) Sound Reactive Led
 

^^ lol bill i was asking the devs or anyone capable to upload to the extras testing repos:) :p

Re: (Announce) Sound Reactive Led
 

haha well I don't know how this is getting done
well I learned it :P

Re: (Announce) Sound Reactive Led
 

I am trying to make a small GUI for this with qt and I would love to know if I can use multiple python files on this app to do the work but I don't know if I can and how to call the python script on a pushbutton for example....

Re: (Announce) Sound Reactive Led
 

If you can wait some days, I 'll make a little desktop applet for this.
I like the idea.

nicolai

Re: (Announce) Sound Reactive Led
 

I have made a small ui file with qt but my problem is that I can not make the buttons to do what the python script that you wrote does. I am not a programmer (actually I am 17 years old and I don't have the knowledge...) but I am thinking of making a gui with 9 tick buttons (3 for rgb led,6 for keyboard leds) and connect them with 9 python scripts just like the first one that you wrote... I also like the desktop applet that you said ;)

This is what I have with the .ui file

Re: (Announce) Sound Reactive Led
 

ledvolume.gz is damaged :\

Does anyone can reupload?

Re: (Announce) Sound Reactive Led
 

I reupload it... Check it now... :)

Re: (Announce) Sound Reactive Led
 

Finally I got autobuilder to import my package into extras-devel.
ledpulse (http://maemo.org/packages/view/ledpulse/).

It does not always work correct if standard notification lights
are enabled. And from time to time one of the three led colours
does not light up as bright as they should (rebooting will help).

Re: (Announce) Sound Reactive Led
 

I will try it right now! Thanks nicolai one more time :D! I think that this thread should me moved to applications...

Re: (Announce) Sound Reactive Led
 

nicolai can you do some more things about this nice software? Is there any way to make the led less sound reactive(because when you have the music on 100%, you can,t really understant if it blinks or not...) Thanks again :D

Re: (Announce) Sound Reactive Led
 

sensitivity slider is needed:D

Re: (Announce) Sound Reactive Led
 

yeap this is what I am talking about ;)
I just updated the first post :)

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

I added a video on first post! Thanks again nicolai :D

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

somehow, I can't get it to work.
Nothing happens after turning on the music player :/

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

Did you click the widget on desktop?

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

I figured out that the desktop icon functions as an on/off toggle.

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

Sure.. :P
I've even checked the widget settings.
But still a no-go

Edit: ok, I was outside when I tried it. Seems like it's giving a 'very low' light (keyboard leds doesn't light up though) which wasn't visable in the sunlight.
But the led is like 80% off.. even if the music is playing

Edit2:
ugh... I just notice that there is a "Source" button, which was pointed to the microphone...

Problem solved! It works :)

Edit3:
Can we add some "Smooth" option so that the led will change from colors automatically instead of always 1 color?
