This flashlight seems pretty cool, but it looks kind of complicated for most people. I don’t think just anyone can put one together. I found a cool site that has a very simple led flashlight. I think just about anyone could make of these.

[...] Well, we have probably all seen the 9v altoid Ipod charger. An example is from the one that Aaron Dunlap has produced. I have to hand it to him. He has done a good job of promoting his idea. We all know though, I hope, that using a 9v battery, and a 7805 voltage regulator to produce a 5v source is a terrible way to charge an iPod. Our friend over at ladyada.net has produced a step up power supply using 2 AA batteries stuffed inside an altoid gum canister. A step-up power supply is basically a DC-DC converter. It allows you to take a small DC voltage and up it to a higher DC voltage. Ladyada does a great job of explaining all of this, and shows how she chose the parts, and designed it. You can buy the kit from her here. This is very similar to the DIY LED flashlight that I wrote about a while back. [...]

Cyberguys have a converter for AA mini mag-lites for $10 US for those of us who can’t solder without burning our fingers.

Hi Os this does sound correct. Some LEDs such as red and yellow have much lower forward voltages (around 1.8 to 2.2). But ones such as white and blue have much higher voltages (around 3.2 to 3.8).

Take a look here for examples:
