Galaxy s4 LCD driver

Hello! I hope im posting this in the right place, has annyone found a driver for the galaxy s4 (or simmilar) LCD panel, i have recently tried to replace the cracked glass and a small mistake later i destroyed the touch capability of the LCD assembly, it would be a waste of a completly good full HD 5" AMOLED LCD so i was wondering if annyone has anny idea if a (fake chinese or something) driver board exists for this LCD so you could plug a HDMI on it ... thank you !

Upgrading the Charging Capabilities of an Android

I would like to know how difficult it would be to swap out the charging port on an S4 for the new hyper charging ports on the new Droid Turbo. I know there is not a lot of free space with in the cell for mods. And I am assuming that the hyper charger is smaller. That being said the tools for a repair swap out do not seem that difficult to master. What else would be needed to make this project successful, a power converter? Basically I want to see if its possible to take the outdated cells people would normally throw away or trade and mod them into something of desire for a cheaper price. Thank you for your time Instructable Community

Get electromagnetic pulses from a gas igniter

Hi, here I have a common gas igniter like this: http://s10.postimg.org/r55cvgt9l/gasigniter.jpg Well, I removed the circuit from the box, then I shorted the two terminals, using various kind of coils (thick wire, thin wire, in various configurations and with different turns), but seems that this circuit is unable to generate electromagnetic pulses; I've tried to turn on a fluorescent lamp, to cause interferences to a pocket calculator (as I can see in various videos on youtube), but nothing happens. If I remove the coil from the terminals I am able to get nice sparks. So, why this circuit won't work as expected? I miss something? However this is the circuit: http://s4.postimg.org/fgd78werx/ignitercircuit.jpg Please note that I'm aware of the fact that these kind of circuit could be dangerous; I'm taking all possible precautions (I'm using it far from any electrical device, I'm using isolated gloves, and so on). I just want to make this circuit for fun. Many thanks.

What Multi-tool should I choose?

I was wounder is anyone could help me pick a multi-tool ether from Leatherman or Gerber, I really don't like swiss army. If it could be around $30 have the some of the following: Knife, pliers or scissors, assorted screwdrivers, file, lanyard, bottle opener, awl and tweezers. It doesn't need to have all thoughts things but some. I am currently thinking about a leatherman Squirt P4 or S4. I have had the Gerber clutch but the pliers broke off and it was really worn out so I thought to get something new. Right now I have the Swiss+tech utili-key on my key chain right now and its basically a knife/saw, bottle opener with a tiny screwdriver on it. I know your going to say to win one but it would be easier just to buy one. Any opinions and review about what you have would be great. Also it needs to fit comfortably in my pocket, it will be going everywhere with me including school so the blade has to be less then 2.5 inches and can not lock.
