How Many Gadgets Are There In The World

Gold is the most precious metal in a phone. A ton of gold ore contains around 1 to 5 grams of pure gold, but a ton of cell phones contains more than 300 grams, says Professor Jason Love. In fact, it is estimated that 7% of the gold in circulation in the world is contained in the circuitry of electronic devices, he points out.

Love is Head of the Department of Inorganic Chemistry at the University of Edinburgh, Scotland. She focuses on the use of chemistry to recover precious and toxic metals from ancient technology. The digital waste that people dispose of offers a huge and valuable resource if the metals can be recovered and recycled through what is known as “urban mining”. You can also prevent the extraction of new materials.

DJI Avata

First person view drones have really taken off recently. Allowing you to put on a headset and fly a drone in first person, these unique gadgets are the closest you can get to flying like a bird.

DJI has released its latest version of this technology known as DJI Avata. It is designed to be more durable and ready for any unfortunate accident. You can control it via a controller or a joystick that mimics your hand movements. It also comes with many smart features, such as the ability to use custom routes, track a person or vehicle, and return to the starting point if you stray too far.

Top 10 Tech Gadgets to Help Students in the Classroom

  1. Laptop

    The accessibility of a laptop offers to a student is essential in today’s culture of portability and instant access. Research, homework, and exams are no longer limited to a certain time of day. Instead, you can choose to log into the online portal for a course at the library or submit a research paper at a café. Having a laptop gives you the freedom to work on your own schedule.

  2. Smartphone

    Of course, a smartphone is great for updating your Facebook status or posting photos with Instagram, but it also has educational benefits. It may not be realistic to always have your laptop with you, but a smartphone gives you access to it at all times. You can check email from a professor, Google a concept you’re unfamiliar with, or quickly scan a website for research developments.

  3. E-reader

    Although e-readers are still primarily used for reading for pleasure, they are now also used in university courses. Publishers are converting many of their textbooks and resource materials to this digital format. This conversion reduces the cost of textbooks for students and eliminates the transportation of heavy books.

  4. Tablet

    The tablet market has managed to merge the advantages of the laptop and the smartphone for the benefit of students. Gives you a full desktop view while keeping mobile connectivity in a sleek profile. Many tablets also offer e-reading apps that you can use to digitally read textbooks and classroom resources.

  5. iPod

    Although there are many different portable media players on the market, an iPod is the only model that offers iTunesU. Teachers and publishers can post podcasts, notes, lectures, resource materials, and further reading on iTunesU. This is another chance to merge your gadgets too. An iPhone or iPad will also give you access to iTunesU, eliminating the need for an iPod.

  6. Wireless Suite

    Your laptop is sure to let you take your research and classwork with you wherever you go. Once home, however, you’ll want to get connected quickly and have the ability to work wirelessly. Make sure your home has a wireless router and printer. Secure your wireless suite from other users by password protecting the network connection.

  7. Smartpen

    A next-generation smartpen records handwritten and audio notes and can link them for future use. The built-in microphone and speaker record and play back your notes or a lecture. Newer versions also allow you to connect the pen to your own app and share content via social networking sites.

  8. Smartwatch

    A highly advanced smartwatch takes connectivity to a whole new level! These watches give you the ability to listen to voicemail and know when you have received a new email. Most models feature wireless Bluetooth for connecting to your phone and email, an ambient light sensor, and a long-range rechargeable battery.

  9. Academic Apps

    Yes, apps aren’t technically a gimmick, but there is an app available for a quasi-academic need. You can manage your daily schedule, create to-do lists, organize notes and plans, find flashcards to help you study, and more. Many of these applications are compatible with the use of smartphones and tablets, and the schedules or data can be shared with other users of the application.

Most online file storage sites have a basic subscription that you can use for free and offer a paid upgrade with additional storage.

The accessibility that a laptop provides to a student is critical in today’s culture of portability and instant access. Research, homework, and exams are no longer limited to a certain time of day. Instead, you can choose to log into the online portal for a course at the library or submit a research paper at a café. Having a laptop gives you the freedom to work on your own schedule.

Pushing the limits

Nanostructures are now produced using complex and expensive lithographic techniques. If you want to create a computer chip with switches and other devices connected by wires, you must first create a circuit diagram. This pattern is placed on silicone or other material and then exposed to an etching medium. Beams of chemicals, light, or particles “cut out” the spaces not covered by the pattern. Some type of metal fills in the etched spaces, producing a circuit board in a semiconductor material like silicon.

These lithography production lines now cost over a billion dollars. Lieber’s technique would provide nanodevices capable of running everything from toys to medical probes to supercomputer chips without lithography. These devices would not only be cheaper but would offer more efficiency.

MicroSD (

SanDisk introduced the MicroSD format in 2005. The company offered a range of capacities from 32MB to 128MB. It didn’t take long for the world to capitalize on the invention, leading to the company to compete with others by offering a large storage capacity of up to 128 GB in 2011. Almost all smartphones, laptops, cameras and computers today can read the format.

Several big names developed the technology together, including Intel, Nokia and Ericsson tried different names. , including MC-Link, Business-RF and Low Power RF.It was Intel who finally proposed the term “Bluetooth”c as the official name of the SIG (Special Interest Group) involved in the development.(tix agb_7)
