How to make powerful led flashlight at home?

I want a compact led light for reading while on the road or on the go. My flashlight is too bulky. And not only is it too bulky, but its less bright than my phone's LED light.

I'd like to buy a replacement iPhone or Samsung Galaxy s3 led bulb, but I wouldn't know how to utilize it. I figure it isn't as simple as a positive and negative contact with a battery. What's a better way to make one?

My Iphone5 won't connect to Wi-Fi? - 1

So basically my phone connects downstairs but not up stairs.

My iPhone will not restore or connect properly?

I have an iPhone 4 on 6.1.3 that I'm trying to update to iOS 7.It connects fine via the USB ports as long as the phone is turned on. However, if it is in DFU or Recovery mode, it does not. I have to restart the program (iTunes, RedSn0w, etc.) to get it to detect the phone, as it will not automatically detect it, and it gets stuck on "Waiting for iPhone." This is an issue, as I'm trying to restore my phone through iTunes. When it gets to the step where the iPhone turns off and is put into Recovery mode for the installation of iOS 7, iTunes can't detect it. I would have to restart iTunes, but then the whole thing would just start over again. If I start restoring already in DFU or Recovery, it won't get past the "Preparing iPhone for restore" step. This may be something with my drivers, and my computer is relatively old. It has been doing this a while now with RedSn0w too. Google isn't much help… Any help is greatly appreciated.

ITunes won't sync albums to my iPhone?

As of right now, I have the most current version of iOS 7 on my iPhone 5 and the most current version of iTunes installed on my computer.

I just got a new windows computer about a week or two ago. I installed iTunes on it, and everything was fine. Just a little while ago, I loaded about five or six Pink Floyd CDs into iTunes and tried to sync them with my iPhone - nothing happened. They didn't sync. I've tried almost everything, and nothing is working. I've been at this for nearly two hours, and I'm getting incredibly frustrated with Apple and it's constant buggy programs.

Is there anyone that can somehow help me?

How did my school do this to their Wi-Fi?

This is all I know: my school has multiple Wi-Fi spots throughout the buildings with different names. They have a same-named one everywhere but requires a password. But the others when I try to connect tell me I can't. I get some type of error on my iPhone. With school laptops they work fine. I'm just curious to know how they did that.

Is the camera on the iPhone 5s good enough for northern lights?

I'm heading to the north of Sweden for a few weeks in January hoping to see the northern lights.
