Title: how to use your E2's camera flashlight as a Torch Post by: rzd4evr on July 31, 2007, 03:43:00 pm modify you E2'S hardware can let the E2 own the torch function
i have post the pictures in it168 but they didn't interest in it sorry of my very poor english ,i am from china Title: Re: howto use your E2's camera flashlight an a Torch Post by: Taurnil on July 31, 2007, 05:28:11 pm Well, this is very interesting.
Is this permanent? how do you control the light? have you made tests about light duration and heating?

Is this permanent? how do you control the light? have you made tests about light duration and heating? it is permanent,you can control the light with a little switch which have two circuit. i have not test about it, i refer the datasheet of the flashlight IC lm3551 which E2 used.

i am from China too but i don't know the knowledge on hardware. Title: Re: how to use your E2's camera flashlight as a Torch Post by: huatz84 on July 31, 2007, 08:46:53 pm Wow...that's cool.But I'm waiting something like mpkg to make our flashlight like E398.That will be amazing as our E2 has a very shining flashlight.

I will try to share it at motofan.ru
Title: Re: how to use your E2's camera flashlight as a Torch Post by: keaglez on August 01, 2007, 03:39:56 am I affraid of hardware mod.. I can 'destroy' my phone.. I have less knowledge about hardware.. I will wait for the software.. Hehe..
Title: Re: how to use your E2's camera flashlight as a Torch Post by: Exploited on August 01, 2007, 03:56:06 am I am not, but I won't be able to find other E2 in my country ;)
When I get newer phone I will beat the s*it out of my E2 :) Title: Re: how to use your E2's camera flashlight as a Torch Post by: Taurnil on August 01, 2007, 08:58:29 am Hi all
well, I checked the datasheet... according to its information, the modification may work: forcing T_F and SD pins to GND puts the LM3551 into low power torch mode (Flashlight); the LM3551 has a thermal shutdown circuit (wich helps a lot :D). LM3551 also has a timeout function (Flash timeout protection). According to the datasheet, you must ground the FTO pin to disable it... but still I see the C466 capacitor in the circuit diagram... Title: Re: how to use your E2's camera flashlight as a Torch Post by: Exploited on August 02, 2007, 12:12:05 am I tried yesterday, but my cheese fingers didn't worked well :) I will try again when I have more time
Title: Re: how to use your E2's camera flashlight as a Torch Post by: Taurnil on August 02, 2007, 08:23:56 am I'm sure this moddification can work if we send the FTO pin to ground directly (removing C466 and putting a short circuit instead), sending SD pin to GND (ground, just like the circuit diagram that rzd4evr posted) and making a well-written mpkg application who switches the flash signal between 0/0V/GND (torch on) and 1/V+ (torch off).
