This video shows the viewer how to start a fire using a steel wool and a 9 volt battery. This is done by first selecting a charge battery and clean steel wool. The gently rub the battery terminals across the steel wool and blow gently. The wool should glow and become superheated.

For years, Samsung has been behind the curve when it comes to fast charging. Up to the Galaxy S10, most of their phones used the very slow Adaptive Fast Charging system. Whether it was the Galaxy Note 7 fiasco or some other reason, Samsung has been reluctant to push the charging envelope. Until now.
With iOS 12, Apple is making up for mistakes from the past, with iPhone batteries being no exception. The new update builds upon both battery health and performance throttling tools introduced in iOS 11.3 by offering users more information about your iPhone's battery usage than ever before.
Before, the only way to really tell how your iPhone's lithium-ion battery was performing was to use tools such as Geekbench and Battery Life, but now Apple has included some quick battery health checks right into iOS 11.
Not all batteries are created equal, but one thing's for sure—they all lose capacity over time. Thankfully, the advanced lithium-ion batteries in your MacBook and iPhone are meant to last for several years before they begin to lose their overall charge capacity.
When it comes to squeezing as much battery life as possible out of our smartphones, most people aim for software solutions, or ones that can otherwise be easily managed right from the touchscreen.
While the Samsung Galaxy Note 2 has an integrated LED for notifications, it only works for a few things, like charging and low battery, and it only flashes two main colors (red and blue) when the screen's off. As someone that usually has their phone on silent or vibrate, it's hard to tell when I receive important messages or notifications. Sure, I could set a specific vibration or ringtone for individual apps, but that can quickly get annoying and distracting, especially at work or school.
Is it possible to cut or chop onions in the kitchen without stinging eyes and looking as if you just watched the saddest movie ever? Before we get to that answer, it's important to know why we tear up when cutting raw onions in the first place. What is this irritant? Are you reacting to the odor? The answer to the latter question is "no," and the irritant responsible is amino acid sulfoxides.
Hydrazine sulfate has many uses, but most notably, it's been used under the trade name of Sehydrin, a treatment for anorexia, cachexia and some even think cancer. But for we DIY chemists, it's useful for something entirely different— as a substitute for the more dangerous pure liquid hydrazine in chemical reactions. NurdRage shows you how to make it via some hypochlorite and the Ketazine process.
In this video tutorial you will see how to Pandora a PSP slim battery. You will need a knife for this. When the normal battery is in the PSP, when you switch it on, it will log on just normal.

For most automotive applications a battery needs to supply a lot of current for a short period of time to turn over the engine and get the car started. With the engine running, the car's alternator produces all the power the car needs. Thin plates inside a starting battery increase the surface area and produce this relative burst of energy. Thicker plates in a deep cycle battery provide a steady amount of current over a long period of time. Deep cycle batteries excel in reserve capacity (RC),...
