Fix a Lightning Cable with Heat Shrink Tubing

We've all seen a Lightning cable that has started to fall apart. They get used every day, and after enough tugs and yanks on your iPhone, they start to fray.

I've seen a lot of these frayed cables, so I've started to fix them before they break with heat shrink tube. I get my heat shrink on Amazon, like this handy and inexpensive pack. I prefer the heat shrink tubes without internal glue - it has higher flexibility and a smaller outside diameter once shrunk.

Heat Shrink Tubing on an Old, Frayed Lightning Cable

In the photo here, you'll see that I slid on a 1.25 inch length of heat shrink over the lighting connector, and then shrunk it into place. I chose a diameter that just barely fits over the lightning connector. In all, it took about 60 seconds to perform this repair.

Warning: the white plastic of the lightning cable has a pretty low melting point. It seems to start to melt at about 125°C (or about 250°F), which is the same temperature that the tubing shrinks. Therefore, strive to minimize the heat and time used to shrink the tubing.

Now the cord has a lot more strength at the point that sees the most stress, and you can't even begin to tell that the underlying cord was falling apart. That doesn't mean that the repaired cord will last forever, but my bet is that its life will extended many times over.

And there you have it. Now go save the life of some Lightning Cables.

One Final Tip

Another problem I see often is that some people are cleaning their cables with "product". Some of these products decay the rubber shroud of the cable. Stick to a water-dampened rag.

Repairing an HP Pavillion DV6 Motherboard

Here's my procedure on how to remove and replace the logic board of an HP Pavilion DV6. My model is a DV6-3122US, and many DV6s of the 3000 series are similar. These machines often fail to start due to a motherboard failure. With a motherboard failure, upon pressing power the fan will first spin and the power light comes on. The capslock key will flash white once every 4 seconds, and the f12 key will stay a solid orange, and the screen - although powered up - displays black only. Although the caps lock "single blink" indicator at boot implies a CPU failure, in my experience it is not due to the CPU itself but the supporting components on the motherboard. The only solid solution is to repair or replace the motherboard. Replacement boards are readily available. I bought one and replaced it myself. Disassembly Procedure NOTE: The screws are different sizes, and its important to reinstall them correctly. I color-coded the different screws in the photos...

Various ways of powering the MikroTik hAP

I have several MikroTik RB952Ui hAP AC Lite routers. They're located in closets, basements, attics, and on desktops. Each location results in different needs in terms of power. Happily, the hAP AC Lite is quite flexible when it comes to power. Here I document the three different ways I have powered my MikroTik AC Lite routers. Power Solutions: Active PoE+ Splitter, Passive PoE Injector, and Standard wall adapter Standard Power: MikroTik (or aftermarket) Wall Wart The default way to power the AC Lite is by using its standard "barrel-style" power port, which is far more flexible than your typical router. The AC Lite accepts power between 10 and 24VDC. When using the MikroTik in a desktop configuration, I use the stock 24 volt MikroTik power adapter . The stock adapter output specifications are as follows: 24 VDC 1200 mA 2.1mm barrel Center Positive Passive Power-over-Ethernet solution: TP-Link Power Injector Sometimes it is useful to ...

Hot (and Cold) Attic Tempertures and Electronic Equipment

An unfinished attic can be an extreme environment for electronic equipment, with conditions that are very unlike what is experienced inside normal living spaces. What's the deal with installing electronic equipment in an unfinished and uninsulated attic? I wanted to install a standard WiFi router in my attic to function as a Wireless ISP (WISP) gateway. My attic is a fantastic location from a radio signal perspective, but it is an uncomfortable place for both people and electronic gear. Although the attic is well insulated, that insulation is on the floor, designed to keep the living space of my home at moderate temperatures. As a WISP gateway, my WiFi router is best mounted above the insulation and close to the roof, where the only protection from weather extremes is the wood of the roof and a layer of asphalt shingles. Equipment Specifications and Extremes Almost all electronic equipment has a set of specifications regarding operating environment. These specifications state the...

Fixing a SodaStream Jet, part 1: Disassembly Guide

I've had my SodaStream Jet for years, and once in a while something has gone wrong. Disassembly is the first step to repair. Start with this article to see how to disassemble the SodaStream, and then once you have that down, scroll through my other articles to see how I repaired specfic SodaStream problems. SodaStream Jet Disassembly Guide Tools Required Flat head screwdriver Phillips head screwdriver 1. Remove the Carbonator. Duh. 2. Remove the black panel lever The front big black tilt lever needs to be removed first. Removing this panel is tricky, but it isn't impossible. Looking up at the bottom of the black panel, there are two tabs, one on the left and one on the right. These tabs fully secure the panel in place. The trick is to use a flat-head screwdriver under the plastic to gently lever the tabs out of the way. Note in the pictures how I approach these tabs with my screwdriver. I usually release the left side first, and then I release ...

Sodastream Carbonator Leakage, Usage, and Weight

SodaStream 60L "Carbonator" CO2 cylinders have a specific weight when empty, plus about 410 or so grams for the CO2 they should have when they're "full". A little while ago I went to buy a replacement Carbonator from my local hardware store. The dealer pulled a new Carbonator out of the box and sensed it was lighter than usual. He put the "light" Carbonator in the "empty" pile and sold me a different one. At that moment I concluded that it would be smart of me to weigh both new and empty SodaStream carbonators. Here are the results. Weighing a SodaStream Carbonator - for both Science and Consumer Protection. The dealer told me that sometimes the carbonators leak after they leave the SodaStream filling facility. That means there could be an opportunity for customers like me to get ripped off! The SodaStream cylinders I buy claim to have a net product weight of 410 grams - and that means that a full Soda Stream Carbonator shou...

Installing the Eve Smart MotionBlind Upgrade with my Large Roller Shade

I have a large window in the front of my house and a roller shade was just the right window treatment for it. But I also wanted to automate it. My MotionBlind Upgrade kit and my new roller shade I looked around to buy something that I was comfortable with, but simple non-automated roller blinds can be expensive, especially when they're larger than 6 ft x 6 ft. This is disappointing, as a roller blind is just a tube with a small amount of synthetic cloth but can easily cost hundreds of dollars. Plus, since I wanted a smarthome blind, we're talking $500 or more from the "service oriented shops". I'm a tech guy. I think can do better. After thinking about DIY and creative solutions, I decided to try out the Eve MotionBlinds Upgrade (MBU) kit. This kit transforms an ordinary roller blind into a smart blind. The MotionBlinds mechanism is basically consists of a small motor and battery in a long metal tube. This motor tube slides into a roller blind ...
