Remarkably, the gadget is appropriate with each Apple and Google object monitoring providers, so you or the giftee can always maintain tabs on its whereabouts. The up to date Stand One Max 3-in-1 wi-fi charger by Nomad is the multi-device MagSafe charger for Apple house owners. The accessory can concurrently charge an iPhone and an Apple Watch at full speed Gadget News, as nicely as a set of AirPods. Compatible with the latest Qi2 wi-fi charging standard, it is futureproof, too. The Troubadour Apex Backpack three.0 is a must-have for on-the-go gearheads with an attractive design and ample space for storing with plenty of compartments.
The Defense Research and Development Organization (DRDO) recently sought interest from companies to develop anti-drone technology. Now, a report by The Hindu has revealed that DRDO has asked BELL, Larsen and Toubro, and Adani Group to develop the tech. In its expression of interest, DRDO detailed how anti-drone technology works and why it is needed. “To mitigate and negate the impact of drones, there is a requirement to develop and deploy counter drone systems for detection, deterrence and destruction of incoming drone threats,” said DRDO in the EOI letter. As per DRDO, considering the unique nature of drones in terms of speed, size, hovering capability and resemblance to birds, no sensor system in standalone will be able to provide sufficient detection, tracking and identification capability to guarantee a reliable and effective defense against threats from drones. Conventional air defense solutions currently available with the country, which are designed to detect large, fast moving aerial objects, are not effective against small, low flying and slow-moving drones. “Therefore, a combination of several types of detection capabilities including emission and reflection of microwave, infrared, visible light etc are required to detect and identify drones,” noted DRDO. How does a counter drone system work? A counter-drone system is designed to detect, track, and identify airborne drones through the utilization of diverse sensors. It facilitates the seamless transfer of this information to affiliated systems, enabling the deployment of counter techniques to thwart their intended operations. These countermeasures include soft kill methods to disrupt functionality and hard kill options for the outright destruction of the detected drones, as per DRDO The system can detect, identify and neutralize different types of drones including Small Hybrid UAVs, Micro UAV/Multi rotor, and Nano UAVs. The Counter Drone System contains several integral components to effectively neutralize airborne threats. Firstly, it incorporates a state-of-the-art drone detection and tracking radar, ensuring precise monitoring of aerial targets. Complementing this radar capability, a day and night camera equipped with laser ranging technology enhances the system’s proficiency in detecting and tracking drones. To implement soft kill measures, the system features a Communication Channel Detection & Jamming system, effectively disrupting the communication channels of the targeted drones. Additionally, a GPS Jamming/Spoofing System is integrated, further impeding the drones’ capabilities through GPS interference. For more decisive actions, a Laser Directed Energy Weapon System is included to execute hard kill strategies. Centralizing control and coordination, the Command & Control Center (C3) serves as the nerve center of the system, empowered by a reliable power source to ensure the seamless operation of the entire counter-drone system.

A private museum showcasing outdated media equipment and tools has opened in Chiyoda Ward, Tokyo.
Otemachi Extinct Media Museum, which began welcoming visitors in January, is the second after its sister facility, the Koenji Extinct Media Museum in Suginami Ward, Tokyo, opened last year.

The museums both boast impressive collections of outmoded telecommunication equipment and media, as well as items that are disappearing from mainstream usage due to the march of technological progress. Visitors can take photos of the items and even pick some devices up to get a “feel” for the ongoing transition from analog to digital-based lifestyles.

The museums were founded by Takuya Kawai, who operates motion picture studios and other facilities, and serves as director of both museums. Kawai, 53, said he is convinced that all types of media — except paper and stone — will eventually go extinct, driving him to collect such tools and equipment before they disappear from society.

“I feel we should pay our respects to the history of each gadget’s development, which was often filled with trial and error,” Kawai said.
The museums now own over 1,000 items and this number continues to increase. About 80% of the gadgets were donated by people across the country who learned about the museums through social media and other means. During the prolonged stay-home period due to the COVID-19 pandemic, many donors are so seeking to get rid of unwanted items around them. The remaining 20% of the items were purchased by Kawai.
The devices at the Otemachi museum — located near Japan’s foremost business district — include old cameras, typewriters, computers, film rolls and floppy disks, among other articles.

The museum levies a ¥1,000 “cooperation fee” to help with the upkeep of the collection and is open weekdays from 11 am to 7 pm in principle.
The Koenji museum, meanwhile, is cramped with items, including flip phones, music players and cassette tapes. The flip phones on display set a trend, and around the year 2000, Japanese manufacturers were hard at work on the development of this style of phone. The facility only opens on Thursdays, from 7 pm to 11 pm in principle. Visitors are requested to pay a ¥500 cooperation fee and order at least one drink.
“I can pick up and touch items that I can usually only see on the internet,” said a systems engineer in his 40s who came to the Otemachi museum from Toshima Ward, Tokyo. “I feel so nostalgic and inspired.” The man spent about two hours at the facility.
Kawai noted: “Many manufacturers don’t keep copies of their goods, let alone retain the products’ online pages, due to corporate mergers or dissolutions. This can also happen for items that were once in fashion. It would be nice if our Extinct Media Museums became places that stir fond memories and affection in people.”
