If you or someone you're shopping for has a newer iPhone model or an Android smartphone like the Galaxy Note 9 or Pixel 3, they come with wireless charging capabilities. Problem is, they don't come with wireless chargers. But there's no better time to snag one than on Black Friday, and we've found the best deals out there for 2018's holiday season.
I was in college, and my 15-inch Sony Vaio laptop was my prized possession. It was my first PC and probably the most important thing I brought with me to my dorm — it was both how I completed my assignments and my primary source of entertainment. How could it turn its back on me in my time of need?
In this rapid fire video, Mr. G introduces us to the idea of atoms, static electricity, and opposing charges. We've all seen a balloon pick up static electricity from a wool sweater and stick to a wall, but watch how the same charged balloon can bend water! For this experiment you'll need a balloon, a wool sweater and a running tap.

Starting February 21, you can preorder your Galaxy S20, S20+, or S20 Ultra. Samsung includes everything you need to get started in the box, but probably not everything you'll want. Let's go ahead and bridge that gap.
Before the iPhone 7 was launched and all the unrealized reports about the phone's features were tucked back into their annual rumor mill, there was some speculation about wireless charging. Specifically, whether or not the iPhone 7 and 7 Plus would support it. We now know they don't, and here's why.
In the first video, you'll see how contact between different materials can result in attraction or repulsion. Experimental results are discussed that led to Ben Franklin's one fluid theory of electricity. It explains how clues were found from rubbing different materials together.
Compared to the original AirPods, Apple's second-generation AirPods have better battery life, Hey Siri support, a more stable connection, faster switching between devices and call connections, less latency for gaming, and an optional Wireless Charging Case.

Simple yet effective, capacitors come in a dizzying array of forms and materials, vital to so many circuits for storage, timing, and filtration - the mighty capacitor!
Nicad batteries often die in such a way that they won't take a charge and have zero voltage. This usually means they're shorted out by crystal dendrite growth. Here's a method of bringing them back to life by zapping those shorted crystal dendrites away with too much current and/or voltage. We'll use a welder as a power source. You could also use a car battery, a DC powersupply, or almost anything with some voltage. Charged-up capacitors are popular for this because you can get a very fast pu...
Despite their awkward appearance, Apple's AirPods have become the earbuds of choice for working out, largely thanks to quality audio without any wires to tangle. However, at $159 to start, they aren't exactly for everyone.
After Apple's recent fiasco, it's now common knowledge that smartphone batteries degrade over time. But aside from causing terrible battery life, a degraded battery can also trick your phone's software into thinking the device has more juice left than it actually does.
Casein is a protein that is found in milk. Groups of casein normally float around in milk without bonding. These groupings have a negative charge. The acidity of the Red Bull causes the negative charges on the casein groupings to become neutralized. Instead of pushing each other apart, the casein starts to clump together causing the milk to curdle and form solid matter.

An atom is a basic unit of matter consisting of a dense, central nucleus surrounded by a cloud of negatively charged ions. The nucleus itself is a mixture of positively charged protons amd electrically neutral neutrons. Different groups of elements have respective atomic numbers. You can use the periodic table as a tool to draw atoms of elements. The periodic table is organized into periods, groups and families. This video is a tutorial that reviews the subatomic particles found in an atom. I...

Richpin demonstrates how to test an alternator with a standard multimeter. First make sure that the vehicle's battery is fully charged. Take the negative lead of the multimeter and put it on the negative post of the battery. Place the positive lead of the meter on the positive lead of the battery. Set the meter to DC voltage using the 20 scale and read the display to ensure the battery is fully charged. Next start up the vehicle and see what the alternator is producing. The display should now...
This is a great video presentation of how Sodium Potassium Pump can maintain a voltage gradient across a cell. It also discusses various things like the differences between positive and negative charges and positive and less positive charges etc. The video tries to explain a lot of things happen within a cell when you fluctuate the voltage of sodium as well as positive and negative ions within a cell. You must watch it yourself to see the changes happen within a cell when you make some changes.
This video is a discourse about saltatory conduction in the neurons. According to the author, it begins with the opening of a gate on the membrane of one of the dendrites of a neuron, and positive charge enters through this gate. The positive charge spreads throughout the cell, and gets dissipated as it spreads, so that, by the time it reaches the Axon hillock of the neuron, it is left with very little potential. However, the potential which results from the simultaneous excitement of many de...
Like a lemon, a potato can produce electricity. This science experiment was prepared by Ebtisam Al Anzoor and demonstrated by Mustafa Daif. The electricity is proven using an analog micro ameter. The positive is copper from a penny or copper coin while the negative is a galavanized nail. The potato releases a charge and is further proven when it is connected to a calculator. You can daisy chain the potatoes for a greater charge.

With over 1.5 billion people on this planet without electricity, it's hard for those of us in developed nations to even fathom how anyone can read, write, repair, or do anything else that we take for granted without any lights. While some of our First World problems pale in comparison, they remain issues nonetheless, one of the biggest being constant battery drain from portable electronics.
Thanks for stopping by to view my Apple Lightning to Micro USB adapter review. The unit comes in a low profile cardboard box and some misc documentation -none of which appear to include any instructions but I think I can figure out how to use it. The adapter is small and well constructed as you would expect from an Apple product and for almost $24 including tax. The plastic encasing the connector is a little larger than with Apple's Lightning cable.
It's been proven over and over that you can make batteries out of fruits and vegetables such as lemons, potatoes, and even apples. Turns out, passion fruit is also acidic enough to power a battery, but Maui Makers member Ryan K decided to take it a step further by adding a laser. Passion fruit, or Lilikoi as it's called in Hawaii, is usually over-abundant in Maui, so Ryan decided to put it to good use. Using anodized bolts, copper pipe, wire, switches, and some LEDs, he built a battery that c...
