[Request] Strobe light using flash
 
Would it be possible to have an app (/widget) to let the flash blink like a strobe light?

It would be something like the flashlight app but with flashes with a frequency bar or something like that

Yes you could do it, to get you started look at my strobe-test code here:

Would be nice if it was beat-sensing through mic

A 'disco' app would be pretty neat. A visualization on the front screen and then a strobe light with the flash, going to the beat. I can already see an impromptu dance party fueled by the N900 lol.

This risks burning out the flash LEDs, if not done with care.

http://wiki.maemo.org/N900_Hardware_Flash_Torch

The LEDs cannot safely be flashed at high power for more than 0.5 seconds.

There is no interlock to stop them being flashed every 0.6s for 0.5s though, and this will almost certainly burn them out.

The maximum sustained current is 50mA - the brightness at which the flashlight uses them.
Any strobe operating at this current is certainly safe.

If it uses more power, it is potentially damaging.

check notes in kernel driver, and this: http://wiki.maemo.org/N900_Hardware_Flash_Torch

Never use flash mode more frequently than explained there! will kill your device!

In torch mode though it's safe, and torch mode is bright enough :-D

Do people really go to parties and discos and hold their phones while dancing, so that they blink and flash in beat with the music?

I had a Motorola E398 that did this. It was dumb then as it is now. Each to his own though.

I would prefer an application to flash morris code with the light. Type something and then have the LEDs show it in morris code. You never know if you will need it.

The "strobe" seems to be on as long or longer than it's off. To get good strobe effects, the light should only "flash" for a short time.

I don't know if the flash on the N900 is bright enough to "freeze" a scene with a short flash....
