5 latest gadgets that you must have

AWAIR

Do you know what the quality of the air in your home is? If not, Awair may be able to help. It measures and analyzes the temperature, humidity, carbon dioxide, volatile organic compounds, and dust in your home’s air, then gives you recommendations on how you can improve conditions to deal with allergies, be more productive, sleep better, and so on. Even if

Awair can’t solve every problem, it will give you the information you need to breathe easy.

BREATHOMETER BREEZE

Drunk driving killed more than 10,000 people in the United States in 2013. Don’t become a statistic, and don’t let inconvenience keep you from knowing whether it’s safe to get behind the wheel. The Breeze is a portable, wireless breathalyzer that links with your smartphone to not only inform you of your current blood alcohol level, but also tell you when you’ll be safe to drive again.

RANGE SMART COOKING THERMOMETER

Simply trusting your eyes when you’re cooking can lead to culinary catastrophe. Connect the Range Smart Cooking Thermometer to your iOS device and then insert its probe into your recipe. You’ll be informed of your food’s temperature so you can hit medium rare or the hard crack stage perfectly every time, and get the news instantly on your mobile device. Choose the Ember model for use with an oven or grill, or Aqua for making candy and brewing beer.

SEAWOLF

Action cams can be a huge amount of fun, but there are some places even they can’t go. TTRobotix is scratching one off the list with its Seawolf, a submersible vehicle that lets you load up your GoPro or other sports camera and capture unique still photos and videos underwater. A heavy-duty carrying case and a miniature surface boat, for transmitting the

signal between the Seawolf and your smartphone or a dedicated remote (depending on model), are included.

WAKAWAKA POWER+

Don’t get caught without power or light just when you most need them. Leave the WakaWaka Power+ in the sun for 12 hours and you’ll store up enough juice to charge your phone, tablet, or other small electronic device when there may not be an outlet anywhere nearby. A built-in emergency beacon and flashlight (rated for up to 150 hours of sustainable illumination) will grant you further peace of mind, regardless of where you are.

Vehicle Parking Management System in C++

this project is developed by Awais Azam Features Graphically display the parking locations(symbolically) Keep record of the arrival and departure of the vehicles with date-time specified Resume the data from the storage Can check history (arrival + departure) Automatically choose the parking location Alarm if any vehicle violate the parking order Description This project is coded in C++ using codeblocks compiler, it has almost 500 lines of code. easy for the beginners in the C++ language , almost each line is commented and explaining its purpose. As per the working of this app , for the first run it create some text files to keep the record of the vehicles , First screen show the menu from which user has to select an option as per his/her need As the screen shows , above is the screen shot of the application, it is not a small project as it looks like it almost cover all the major topics of C++ (not OOP) you can als...

Explaination Of Electron Gun

Thomson discovered the electron using this concept in 1897 after conducting experiments with cathode rays and studying their uses. Electron guns are a very versatile electrical component. They are essential to a number of devices, from 3D printers and welders to the large synchrotron at the Diamond Light Source in the UK and the electric systems of Kimball Physics in the US So how they work It’s all down to kinetic energy and electrical currents. When installed in an electrical device’s vacuum tube, the gun turns electrons and ions into usable beams of energy by releasing them from their metal source (cathode). This process is known as thermionic emission. Inside the gun there is a small filament that heats the cathode, which makes it release a stream of electrons. The electrons accelerate rapidly and the resulting beam is pulled toward the neighbouring anode, which is positively charged. There are small holes in the anode which allow some electrons to pass through, so a...

Sonic Weapons

To disperse crowds and prevent rioting, various forms of non-lethal weapons (NLW) are used. Among these, interestingly, is sound. Known as an acoustic or sonic weapon, infrasound (superlow frequency) and ultrasound (super-high frequency) greatly affect human ears. They can disorientate a target and have psychological effects as well as physical effects of nausea and damage to blood vessels. Explanation Ultrasound can be increased to 120 decibels (the same volume as a jumbo jet taking off), which is considered the human pain threshold. In contrast, infrasound feels like a damaging vibration or pressure wave, as it’s at a frequency too low for humans to hear. When exposed to high levels of sound, the influx of energy has a painful effect on the body. As well as huge decibels of volume, the variations in frequency can also cause damage. For instance, an infrasound of seven or eight Hertz can rupture blood vessels. Certain types of sound within the frequencies we are able to he...
