Install Dual LED Flash for HTC Diamond2 camera

HTC Touch Diamond2 T5353 phone has a very good camera. It is also better than some cheap compact cameras too.
But it has no flash. So it cannot takes photo in the dark.
So I try to install flash for it.

I use dual LED AGILENT/AVAGO HSMW-C191. It costs 15 THB per each.
Advantage:
- It can uses up to 3.9 Volt maximum of power supply, which equals to Diamond2 battery. No need to drop the voltage.
Disadvantages:
- It produces less light compare to LED flash on newer camera phone.
- It produces too much purple.

I'll try to change LEDs later.

Circuit (Maybe???)
