Eavesdropping from a distance can be tricky because it usually requires some sort of bug or transmitter. It's easy to transmit audio through lasers, but you can also use lasers to build a microphone that picks up audio from a distance. LucidScience built the Laser Spy System for about $20. To make your own, you'll need a cheap laser pointer, an NPN phototransistor, a headphone amp, and a few other small pieces listed below. A light-to-sound circuit is installed in a small plastic box with the...
At one time or another, we've all enjoyed the visualizations that came stock in Windows Media Player. I remember spending hours listening to my favorite album, putting the graphic equalizer on full screen, and getting lost in the flurry of colors that would dance across the screen. Well, now thanks to the imaginative mind of Instructables user yardleydobon, you can now recreate this rainbow-colored music visualizer right on top of your freaking head—with these trippy EL wire headphones, which...
You can add Bluetooth capability to an old stereo, a retro mouse, or even your car's cassette deck. If you can think of a device, someone has probably found a way to control it with Bluetooth.
Most of us have given up our big, bulky stereos in favor of smaller, sleeker models, but how many of us actually get rid of the old ones? If you don't like the idea of throwing out or giving away electronics you spent good money on, you can always upgrade them instead!
If you've ever been on your way to a party and felt that your outfit just wasn't flashy enough, engineering student 'Rambo' has got just the thing for you. His homemade LED suit lights up and dances to the beat of the music, and can even be controlled via Bluetooth.

In this Education video tutorial you will learn how to simplify an exponential expression in algebra. There are neither audio nor typed instructions in this video. It is a demonstration of the steps involved in the process. To do this, simply expand the exponentials and then multiply or divide in steps to solve the problems. These are illustrated by a few examples in this video. 3^5 = 3x3x3x3x3 = 9x9x3 = 81x3 = 243. X^6/ X^2 = (x.x.x.x.x.x)/ (x.x) = x^4. 7^2 x 7^15 / 7^13 = 7^17 / 7^13 = 7^4....

Have you ever seen ads or a movie where the film goes on rewind, bring you back through time for whatever reason the director intended? This happens a lot in paper towel commercials, where you see a coffee stain get removed as the coffee pours itself back into a cup while the dog's footprints also disappear one by one as he gallops backwards to the front door.
Your iPhone's built-in Voice Memos app is a great way to record the audio around you, whether it be conversations, lectures, meetings, interviews, discussions, chitchat, gossip, or other kinds of talks. But if your goal is to record audio on the down-low without being noticed, you'll need to know the hidden shortcut.
On May 17, Apple announced that Lossless Audio playback for Apple Music was finally coming to subscribers in June. The long-awaited option will let users stream songs at a much higher quality than ever before. Still, in the fine print, Apple noted that you wouldn't be able to listen to the best sound quality — Hi-Resolution Lossless — on your iPhone without a DAC.
On a PC, you can play sound from multiple apps at once. It's great, but it can also be confusing — there's a volume slider in each app, then the system-wide one, and probably another knob on your speakers. To avoid this dysfunction, Android only has one sound stream for media. But that has its own problems.
The sound your iPhone makes when you connect it to a power source has been the same for a long time. Unfortunately, it was never possible to change that chime to something different without jailbreaking first, which opens your iPhone up to malware and hackers. Thankfully, iOS 14 has changed that.
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.
Apple has their regular iPhone 11, then two higher-end "Pro" models. Samsung went the other way — they have the Galaxy S20 and S20+, then there's the S20 Ultra. But one thing these smartphone lines do have in common is the base model flagship. How do they compare?
Sorry, Galaxys S11–19, Samsung's jumping straight to Galaxy S20 this year. They're also going with essentially three base models before accounting for niche variants. Of these three models, it's clear which one's the best: the Galaxy S20 Ultra.
There are plenty of jokes out there about the battery indicator on iPhones. Some people complain about their iPhones dying randomly at 11%, while others see hours of use at the 1% mark. Despite its inconsistencies, that battery percentage is a useful tell for how desperate you need a charger. There's just one problem: the icon is hiding on your iPhone 11, 11 Pro, or 11 Pro Max.
The punch hole design of the Samsung Galaxy Note 10 has challenged users to find a clear way to deal with it. Although it's less intrusive than a notch, if left unaccounted for, it can be just as much of an eyesore. One of the more creative ways we've found is to use as a battery indicator.
After months of back and forth, ZTE is finally making their return to the United States. The last phone the Chinese company released here was the Axon 7 Pro, a low priced flagship phone that competed well against the OnePlus 3 and 3T at the time. Its successor is the Axon 10 Pro, which adopts the same strategy.
Apple shocked us all yesterday when it released iOS 13.1 developer beta 1. It was an unprecedented move since iOS 13.0 is still in beta testing and since Apple has never pushed out a "point" beta release before the stable base version. And now, you can get your hands on iOS 13.1 for iPhone if you're on the public beta.
Apple's upcoming update for the iPhone, iOS 13, is introducing over 200 new features. Many of those were never formally announced, instead silently released in new updates to the beta. After eight developer beta cycles, we were anxiously awaiting the release of developer beta 9. What we got instead, however, was the first iOS 13.1 developer beta.
September is nearly here, which means new iPhones are, too. We're looking forward to iPhone 11 Pro and 11 Pro Max, as well as the more affordable iPhone 11R. All three iPhones will run iOS 13, so Apple's entrusting beta testers to ensure its new OS is ready. The latest update, developer beta 8, is now here for us to test.
Apple dropped the sixth public beta for iOS 13 today, Aug. 15. This public update comes just hours after the release of developer beta 7, an interesting move for Apple. The company has recently stuck to a schedule of seeding the public beta at least one day after the developer beta, presumably to weed out any debilitating bugs that might have gone unnoticed.
Apple's sixth iOS 13 developer beta was a welcome update for us beta testers. New options for toggling Dark Mode, a way to hide website previews when peeking links, plus UI changes made for a significant iOS 13 upgrade. We're hoping Apple continues this trend of fun and excitement with the release of iOS 13 dev beta 7.
Life's pretty good for iOS public testers — we get to check out new iPhone features months before the general public even knows they exist. That said, we aren't first to the party. Developers get priority during beta testing, as evidenced by yesterday's iOS 13 dev beta 6 release. It's not all bad though since Apple just released the public version of that software, public beta 5, this afternoon.
If tradition holds, we're roughly one month away from Apple's big iPhone announcement. While we're excited to see what will mainly be a significant camera upgrade, it's not all about the hardware. Apple will also release the official version of iOS 13 to coincide with the iPhone XI. Before then, however, iOS 13 needs beta testing, and developer beta 6 just hit on August 7.
Apple just seeded the fourth public beta for iOS 13 to software testers today, Tuesday, July 30. AppleSeed participants saw this beta one day early, alongside the release of developer beta 5. Now, developer and public testers alike are up-to-speed with the latest in iOS 13.
Beta testing for Apple's big upcoming iPhone update, iOS 13, is well underway. So far, each of the four beta versions we've seen brought new features and changes to the table, many of which were never even mentioned by Apple during WWDC in June. Now, it's time to do it all over again, as Apple just released the fifth developer beta for iOS 13.
