[REQ] Theremin using the lightsensor - Touch Diamond, MDA Compact IV Themes and Apps

Just a mind spill, it might be cool if you could play a Theremin on the diamond using the lightsensor as modulation?
So if you place your hand near / over the light sensor it modulates (pitch) the sound,
like with a normal Theremin.
And maybe the second modulation (volume) could be done by a slider via the touchscreen.
To calibrate the lightsensor it should take the value it has when the program starts or a button to set the max value via the amount of lux currently provided to the sensor, this way it's possible to 'finetune' it to specific frequencies.

Automatic screen brightness using camera or Light meter

it is possible ?
I'm using the KAISER, when in a building i set the brightness to low becuase it has a very bright screen and it's just a waste of battery
But when i go outside i can't see a thing, need to set it to high again
And then i just forget to set it to low again
is it possible to make it be automatic ?
(bright outside - high brightness, dark outside - low brightness)
Thanks !
p.s.
does the KAISER have a light sensor like the Universal's keyboard light sensor ?
if so, is it possible to use that ?
ah man i hear you. when my sister got her blackberry pearl, and i saw it automatically change brightness, i was jealous. aha. unfortunately, the sensor is hardware thing.
i'm not sure about the kaiser but i know the hermes has a keyboard light sensor, but it's on the keyboard, and only says whether to turn on the keyboard backlight or not. not too useful, i'd think.
Hermes and Kaiser have front cameras...
but camera is a no-no for battery
Even once a minute, or on power-on?
Well, maybe yes.
I nice Solution would be a Button you press it, and the Brightness gets configurated automaticly: perfect for battery because you do this only on need!
And there could be a standart brightness reseted after having standby on
I dont know how to use the Camera in VB.Net someone knows?
I was thinking more in the direction of the front camera and the timer ....but bettery above all .... if it is possible it would be awsome !
the buton pressing idea is (forgive me) pointless ... if i wanted to press a button i might as well press the on screen button i already have ! (spb mobile shell)
thanks for the idea though !
it's great to see so many people taking interest, hope it will stick !
SPB software is my solution. You can map your jog dialer for brightness. I use that for volume, so I use touch screen to slide my brightness.

look at the screenshot or demo. Map the brightness as botton4 is a option because brightness is a program link for you to set what ever button as you wish.
blah, i have an at&t 8525, so i forgot about the front facing camera. my current solution is to set the backlight to reasonable indoor setting, and i have VJLumos mapped to my Button5 press&hold. so whenever i go outside, I run VJLumos, and when I get back inside, I run VJLumos again (which turns it off) and it automatically goes back to the previous backlight setting.

Automatic Light Adjustment

I've just bought a Touch 3G and as far as I can tell the Auto setting for the Backlight doesn't seem to do anything. As my last phone (P3300) didn't have this, what should I be expecting to happen? I've tried putting a finger over what I think is the sensor (right hand "LED", beside speaker) and nothing changes.
Thanks, W.
Did you set Auto adjust backlight in system menu?
Imho it is a really subtle effect. You can see it a bit when holding the light sensor (right to the speaker) to a bright light source. The display then gets a little bit brighter.
If you would like to increase the effect or customize the stepping, try g-light ( http://www.ageye.de/index.php?s=glight/about ), it lets you set specific values for each reported value from the sensor, and set the polling interval
Jade auto adjust is poor
I had the diamond prior to purchasing the jade. The diamond auto light adjust was very noticeable compared to the jade. In fact I didn't think the Jade even had a light sensor until one of the other users pointed it out.
After a little research I found this thread. http://forum.xda-developers.com/showthread.php?t=450318
I used it on my Jade and it works great. One of my problems with the diamond was the fact that the light would not automatically dim enough in low light conditions.
Thanks for the link. Now using G-Light which works pretty well. Not perfect as its sometimes a bit erratic but certainly makes better use of the light-sensor than HTC!

How to decrease backlight while keeping auto adjust?

Hi!
I wonder if there is a way to lower the backlight levels on auto adjust (or increase for those who think its still not bright enough). Point is I think having the backlight on generally lower levels will naturally increase battery life. I know I can change the the brightness to a fixed level that suits me - but that would just be right for the current situation. I still want it to adjust to different lighting situations. Ideas?
It would be nice if it was possible to change how dim the backlight gets on total darkness and how bright it gets on your average sunny day.
I've been messing around with the reg to see if I could find max and min values but I can only change manual settings, not auto mode using the light sensor.
One note though: The sensor itself uses battery to measure ambient light. That being said, if you spend most of the day under a constant light source (say an office) manually dimming the device should consume less energy since the sensor is not doing much good for you anyway.
I guess it's not your case. I had this app on my Cruise to change backlight intensity. never used until now. it works on leo (running 1.48 but that should not matter) and changes backlight in 25% increments. You can copy a shortcut to the startmenu and add a quick link to your home tab or map it to a hard or soft button somehow.
I wold really like to know how to change max and min levels on auto backlight.
Try Lumos - it's a backlight replacement that allows you to customise how you want your auto backlight to work, ie. what the minimum/maximum brightness is, how fast the backlight changes, etc.
http://forum.xda-developers.com/showthread.php?t=450318
Seems to work fine. Still some tunning to do. Thanks!
I'm using Lumos now and it works great! Simple to set up and easy to customize. Thanks for the hint!
lumos is great but I found it was draining the battery quite fast on the leo.
Admittedly I was using it with the wm6.5 Check for active programme only setting. I never tested it to see if it worked without checking that box.
As far as I can tell by now the batterylife appears to be rather better than before. I haven't put in any application exceptions and didn't check the one checkbox in the settings tab. I also use a custom curve where the backlight stays at 30% until the sensor hits about 400 (30% is plenty in my opinion and still brighter than my friend's iphone in normal light condition inside).
you should try AutoLight http://forum.xda-developers.com/showthread.php?t=548402
it works fine on Leo

Proximity problem

Hello,
I have bought myself a diamond touch 2, and i directly flashed it to Dutty's R6 rom because i like it much better and i made up my mind about it even before i bought it.
Now i seem to have a problem, and i don't know what would be the problem; either the device or the rom?
Proximity doesn't work; setting automatic backlight dimms the screen to a low-light level. Holding a flashlight above it doesn't make any difference.
Also, when making a call, the display keeps being illuminated the whole time, no matter if i hold it to my ear or not.
Does someone recognize this problem?

Settings\System\Power\Backlight\ Turn off Auto adjust.
If i turn off auto adjust i can indeed set full brightness, but that's not the point. I want the auto-dimming and proximity sensor to work, so when i hold the piece next to my ear it locks and turns off the screen...
If I turn on auto-adjust, it doesn't respond on any lightchange or action; it just dimms the screen to about 40% and keeps it there.. either a bug or a hardware fault with my unit?
Not sure that it ever worked perfect out of the box.
Have you tried tweaking the settings with TD2 Tools?
How do you mean tools? As far as i know i can only find one box to turn auto adjust on.. you have the same configuration, does it work for you?
EDIT: I installed the app "LumosWizard". Now the phone's backlight adjusts depending on the light the sensor receives. The sensor works well as the values go up when putting a flashlight on it.
However, i wonder why this doesn't work with just auto-adjust on, that's what the HTC Auto-Backlight should do right? Also, with this app, the backlight doesn't go out when no light is reveived (auto-lock when putting into pants, or turned off backlight when calling...) ?
This is what i'm looking for: http://www.youtube.com/watch?v=6xakUmz1zwc
=> i don't think this is achieved by an additional application, but is just standard HTC service doing this because of putting on the auto-adjust...
There is NO proximity sensor on Touch DIAMOND II. Only light sensor. Use Touch_InCall_Screen_Tweak instead. This program use G-sensor and block the screen when your phone is in vertical position.

Thanks, installed and works good!
Still wondering though why i need a 3rd app like LumosWizard to make the lightsensor work, as htc's autoadjust apparently doesn't
I did find this .cab called Glight and it works great on my TD2

[Q] Auto-brightness Sensor

I am currently running JPA/JPB Hybrid firmware and I was wondering if there even is a sensor for the auto-brightness.
Normaly I have set my brightness to the lowest level, which is enough for indoor usage. But as soon as I am outdoors in the sunlight I can't even tell if the display is on or off with this brightness level.
Now the strange thing about this is that it does not seem to make a difference whether you check the "Power saving mode" in the Display settings or not - the Display brightness always stays the same:
- with the highest level it does not get darker in very dark rooms to save battery
- with the lowest level it does not get brighter even in direct sunlight, which makes the display unusable
On the left of the Samsung-logo there are 2 "holes", I guess one must be the proximity sensor and the other one the brightness sensor?
Is there any way to have the brightness on a very low level in dark rooms and on a high level in bright rooms / outdoor WITHOUT switching manually? Even switching with a widget sucks, because outdoors the display is so dark that I can't even draw the pattern to unlock the screen first (at least not without covering the display from the sunlight)
If there is I think the driver is missing so it's useless.
There is a brigness sensor, not for auto adjusting the screen brighness, for example try *#0*# and press sensor, now if you put you finger on the sensor, you phone vibrates, it means it is dark, if your finger is not on the sensor, it says, its brighten outside, that is for example to telephone, the screen goes dark, when you put the phone to your ears
"that is for example to telephone, the screen goes dark, when you put the phone to your ears"
No, that's the proximity sensor, and I think there is no light sensor in SG3, because that test app shows only proximity, accelerometer and magnetic sensor.

Power Saving is not for dynamically change the strenght of backlight. It's just turning to lowest level when your battery is 15% and less.
And there is 2 holes, for proximity sensor. Try to cover one hole, and it doesn't work. Why? Because 1 hole sending an infrared (I think...) wave, and second is receiving that back, from eg., your hand.
