Just about every household gadget we own runs on 1.5 volt batteries of one size or another. Wouldn't it be great if you could reuse all of those dead AA, AAA, and D batteries after they've passed on? It turns out you can make a simple circuit called a "Joule Thief" to reanimate the undead flesh of your deceased batteries and create a zombie battery.
What Is Ferrofluid? Ferrofluid is a black, solvent-based liquid, that, in the presence of a magnetic field, becomes strongly magnetized. The fluid is made up of nanomagnetic particles coated with an "anti-stick" or surfactant compound, suspended in a "carrier", commonly an organic solvent. For mechanical applications, it is used in hard drives and speakers as a lubricant. However, it also has been implemented in artwork, as seen in the video below.
There are countless ways in which you can turn your love of tech and coding into a full-fledged career — from developing apps and websites as a freelancer to working in the IT departments of small startups or major tech companies.

When it comes to augmented reality smartglasses, for now, it's still a mostly enterprise world, since the form and function of most are more acceptable on a job site versus your local cafe, and the still high price tags are far more palatable to major companies rather than individuals.
When you have minor software issues like an app crashing, restarting your iPhone would usually fix it. But Apple doesn't provide an official "Restart" or "Reboot" option (unless you count this bold text hack), so we typically have to power our devices off and on in these scenarios. Thankfully, there's a great Cydia tweak that lets you "respring" your device, which is even faster than restarting.
The Google Assistant is great about understanding what you actually mean, so you don't have to issue exact commands like you do with Amazon Alexa, for instance. But even though it's a master of colloquial speech, it could still be better, and that's where shortcuts come into play.
With the announcement of Google Glass Enterprise Edition last week, a literal behemoth entered the arena of companies serving augmented reality solutions to business customers.

Today in Santa Clara, California, at the Augmented World Expo, Scope AR revealed a major new update that will add markerless tracking for their remote assistance application, Remote AR, on standard devices.
Those of us that work with or around augmented and mixed reality have seen a powerful shift in the last year as the popularity and interest have grown in the field.

Trimble is integrating its mixed reality applications into the DAQRI Smart Helmet to enable outdoor and on-site support for design, construction, and heavy industry as part of a collaboration the companies announced today.
With smartphone makers ditching the headphone jack in the hopes of a truly wireless future, we're having to rely on Bluetooth devices like earbuds and headphones more and more. But the downside here is that these devices aren't physically connected to your phone in any way, which makes it way too easy to leave an important accessory behind.
This week, Dr. Sung-Hoon Hong, Vice President of Samsung Electronics, announced at the Virtual Reality Summit in San Diego that not only does Samsung have a new virtual reality headset coming, but that Samsung intends to enter the field of augmented reality, too.

Want to actually catch 'em all? Pokémon GO has long-teased the opportunity to hunt for Pokémon in the real world through augmented reality, but few have had the opportunity to actually see it in action.
Shopping for a new phone is an entire ordeal. Even when you've narrowed it down to a few choices, comparing the finalists can be difficult, because specs and prices are scattered around on various different manufacturer websites, and if you're trying to do this on your current phone, most of these websites aren't optimized for mobile viewing.
Windows 10 definitely has a sleek and modern look to it, but some of these visual changes have been made at the expense of functionality.

When you send an emoji from your Android device to someone that uses an iPhone, they don't see the same smiley that you do. And while there is a cross-platform standard for emojis, these don't work the same way as unicode-based smilies or dongers, so not every operating system displays these little guys the same way.
With the sheer amount of photos, videos, and miscellaneous files we place on our computers, proper organization becomes necessary. Not only so that we can quickly get to a file when it's needed, but also to declutter folders and keep them from looking like random file dumps.
Apple introduced Touch ID on the iPhone 5S back in 2013, which let you unlock the device with your fingerprint. While it was an impressive feature, it could only do that one thing—unlock the device.
I'm a long-time and loyal Android user, but one iOS feature that I'm truly envious of is their keyboard shortcuts, which lets you assign a short macro that inputs a longer phrase. For example, typing "home" can input your home address.
There are a lot of instances where we find ourselves typing virtually the same phrase that we've typed many times before. Whether it's the standard spousal reply of "I'll be home in a few", or a work-related phrase like "I'll have that to you by the end of the day", typing phrases like these can feel very redundant at times.
