![]() ![]() But he found his apparatus emitted a strange warbling tone, which he could shape by moving his hands around the equipment. In 1920, he invented a machine that aimed to use the new-fangled technology of radio waves to measure some properties of gas. Born in 1896 in St Petersburg, he showed precocious ability as a child engineer, reputedly dismantling and reassembling watches and other mechanical items by the age of seven, and constructing an astronomical observatory by 15. The theremin was invented around 1920 by Russian physicist Lev Sergeyevich Termen – commonly known later as Léon Theremin. “Coming from a classical background, learning cello, the theremin just seemed otherworldly to me.” “I think it just has so much unexplored potential – and it is also mesmerising visually,” says Icelandic musician Hekla (full name Hekla Magnúsdóttir), who combines theremin and voice on her albums, most recently 2020’s Sprungur. And now the theremin is inspiring a new wave of artists, its modern renaissance aided by documentaries like 1993’s Theremin: An Electronic Odyssey. Invented 100 years ago, the world’s first electronic instrument inspired a surge in sound technology that led to Robert Moog’s creation of the modern synthesiser, transforming the musical landscape ever since. Meet the only musical instrument controlled entirely without physical contact. Its music seems conjured from nothing, notes and tones teased and manipulated by hypnotic movements of hand and fingers through air. ![]() The theremin sometimes seems like an instrument from Earth’s future or another world. ![]()

Support for WiFi Direct is quite patchy, however. ![]() While Miracast is its own standard, it builds upon the WiFi Direct technology to allow for secure screen mirroring. Other WiFi-specific brands, such as Miracast, also use WiFi Direct to communicate. It also plays a central part in other systems and communication standards, such as near field communication. Like Bluetooth, you can use it to send files, share your screen with other devices, play games directly, share your internet connection, and more. This allows for a seamless (yet secure) connection between the devices. WiFi Protected Setup (WPS) is then used to authenticate, with a push button or PIN code used to establish a connection. WiFi Direct works by enabling a software-generated access point on the host device, creating a temporary WiFi network in the process. You don’t need an existing WiFi network to connect to, as the connection is made directly between two devices. WiFi Direct is a standard that allows the use of WiFi radio frequencies (typically 2.4GHz and 5GHz) to make direct, peer-to-peer connections with other devices. There are plenty of devices that support WiFi Direct (under various names), so if you want to know more about WiFi Direct in Windows 10, here’s what you’ll need to know. Windows 10 has direct WiFi Direct support, but if you’re planning on using it, you’ll need to know what it’s good for (and whether it’s safe to use it or not). ![]() |
