Most of the components are accessible without much fuss, though the glass and LCD are fused to the frame.
The Nexus 5 has received a good grade for repairability from the folks at iFixit.
Spelunking its way through the innards of the new Nexus, iFixit found most of the teardown trip relatively carefree. The panels are stuck together with plastic clips rather than glue, making the removal much easier. Alas, the bottom of the case did sport some adhesive, but that was quickly removed through one of iFixit's magic tools.
The antennae for the Wi-Fi, MIMO, and GPS are nicely labeled to prevent any confusion. The battery is held in place by just the right amount of glue. The speaker also pops out with minimal effort. iFixit again had to use one of its tools to lift up the motherboard, eventually uncovering a Broadcom controller that handles the NFC (near-field communication) technology.
After removing the earpiece speaker, headphone jack, and front-facing camera, iFixit received a curveball. The phone's front frame, LCD, and glass are fused together, presenting a challenge if the screen ever cracks.
The final grade: 8 out of 10 on the repairability scale (10 being the easiest to fix).
iFixit liked the Nexus 5's modular internal design, mild adhesive to hold the parts together, and standardized screws. Only the fused front assembly earned a thumb's down, which means that "fixing broken glass will be either expensive or very difficult."

The Samsung Galaxy S 4 already gives you a large window on the world. Here's how to make that window even larger by connecting it to your HDTV.
The Galaxy S 4$99.99 at Amazon is Samsung's largest Galaxy S smartphone yet, with a whopping 5-inch 1080p HD display. It's great for playing games, watching video, and browsing the Web. But sometimes 5 inches doesn't cut it, especially when you've got a 60-inch HDTV sitting right in front of you. Luckily, there are two good ways to connect the Galaxy S 4 to your TV, and we've outlined each of them for you right here.
MHL AdapterThe most foolproof way to hook your GS 4 up to most HDTVs is with an MHL adapter, which allows you to mirror everything you see on your phone's screen on your television set. You can find an official $39.99 adapter from Samsung online, or you can shop around for a no-name part that's a heck of a lot cheaper.
The advantages to using MHL are crisp stereo sound and an uninterrupted video connection. The downside is that most cables are short, and you'll probably need to get up every time you want to change what's playing.
To set it up, you'll need an MHL-to-HDMI adapter, as well as an HDMI cable. Remember, the longer the cable, the longer the reach you'll have from your phone to your television. The MHL adapter plugs into your phone's micro USB port, and you need to connect your phone's wall charger to the port on the side of the MHL adapter. Then plug the charger into the wall, connect your HDMI cable to the adapter, and plug the other end into a free port on your television. To get the best audio quality, pull up the Settings menu on your phone, then navigate to My Device > Accessory, hit Audio output, and select Surround.
Samsung HDTVs, Blu-ray Players, and AllShare Cast Wireless HubYou may have noticed an option for Screen mirroring if you've already spent some time exploring the Settings menus on your GS 4. There are a couple of ways to do this.
The biggest advantage to wireless mirroring is the freedom to move around with your phone while still sharing your content on the big screen. This is especially helpful if you're gaming, or even if you're just browsing through a bunch of YouTube videos with some friends. The downside is that video and audio can sometimes cut out, and audio has a tendency to lag. It's also a lot more expensive to set up if you don't already have a compatible device.
The first, easiest way to use wireless mirroring with your Galaxy S 4 is if you have a compatible 2013 Smart TV from Samsung. You can also use a Samsung Blu-ray player with AllShare Cast, like the BD-F7500. You may not have either of these, but the good news is that you can buy an AllShare Cast Wireless Hub from Samsung, which allows you to turn any HDTV into an additional display for your phone. Note that this also works with phones like the Galaxy S III and the Galaxy Note II, as well as tablets like the Galaxy Note 10.1$449.99 at Office Depot.
To connect wirelessly, go to your phone's Settings, then tap on Connections > Screen mirroring. Turn mirroring on, and your compatible HDTV, Blu-ray player, or AllShare Hub should appear in the device list. Choose your device and mirroring will begin automatically.

In this article, I'll explain step by step how low voltage Premise and Outside Plant (OSP) cable is made. This includes Cat3 telephone cable, Cat5e, Cat6, Armored, Gel-filled and more. Enjoy
Copper Rod Breakdown
The first step in low voltage cable production is copper rod breakdown. Copper is sent to the factory in 5,000lb coils. These copper coils are continuously drawn through diamond dies that drastically reduce the diameter of the copper to 10 or 12 gauge. Lubrication is used during this process to reduce the amount of friction and heat on the copper cable. Once completed, the copper is stacked in vertical coils, called Stem Packs. These stem packs are then transferred to another drawling operation that further reduces the gauge of the copper. During this stage, the copper is also charged with an electrical current. This anneals the copper, which is a softening process. Once annealed and cooled off, the copper runs through a laser measurement system, to verify it is within manufacturing specifications.
Copper Insulation Process
The copper insulation process is continually monitored and controlled up to +/- .0001". Once the copper is insulated, it runs through a water cooling trough, allowing the wire jacket to properly harden.
Copper Twisting
Twisting helps reduce crosstalk between the individual pairs of wire. Some Cat6 premise cables include a center spline, or wire separator, to further reduce crosstalk and increase performance. Copper twisting is accomplished by running each individual wire through multiple faceplates. This helps control pair position. Once twisted, we have what's called a Cable Unit.
Jacketing
The cable unit then goes through the jacketing process. This step varies, depending on what type of cable your manufacturing. OSP cable typically uses a black polyethylene or UV rated Polyvinyl chloride (PVC). For Cat3, Cat5e and Cat6 Premise cable, varying grades of PVC are used, depending on flame safety rating requirements. This steps starts off with molten plastic being extruded at high pressure and formed around the moving cable core. Shielding, ripcords, armoring and water blocking compound may also be applied at this step. Cables that require dual shielding or double armor will need to repeat this process. Once completed, the cable passed through a long cooling bath, then through a laser micrometer to verify the final diameter.
Printing
Printing is done just before the cable is put in it's final packaging. For OSP cable, a hot foil printing process is used, that leaves an indented print in the cable jacket. For Premise cable, a high speed ink jet printer is used. Some cable manufacturers print footage marking from 1000-0ft, making it very easy to determine how much cable you have left in the box, or measuring out cable runs. Other manufacturers use a 6 digit footage mark, making the process a little harder.
Coiling
The completed cable is then wound onto a reel or coil. the coiling process requires very precise tension controls to insure the cable won't tangle when being pulled out of the box.
Final Testing
Once the cable is printed and coiled, it goes through one last set of tests. The manufacturer will test it against a large set of mechanical and electrical performance specifications. Once tested, the cable is ready for shipment.
