The Crossfire transmitter perturbs the usual functioning on HDZero & Avatar HD FPV Goggles. If you get closer to the goggles’ power cable or goggle, the goggle will shut down or reboot. This video presents two solutions to solve this issue.

00:00 – Video starts.
00:07 – The problem (Crossfire emission power 250 mW)
00:35 – The problem (Crossfire emission power 500 mW)
01:08 – First approach: using a ferrite cable clip.
03:07 – Second approach: using a capacitor as a low-pass filter.
04:27 – Conclusions.

Mitch Lee can tick off the many environmental advantages of electric boats versus ICE counterparts that rule the waves: No exhaust fumes and pollution. No oil slicks trailing in the wake. No guzzling of pricey marine fuel at 2 kilometers-per-liter or less.

But with all respect to the Sierra Club, Arc Boats isn’t in business to save the planet.

“The climate benefits are certainly there. But our goal is to deliver better boats, period,” says Lee, the CEO and former Boeing engineer whose cofounder and CTO, Ryan Cook, is the former lead engineer of Space X.

Austrian startup CycloTech has unveiled CruiseUp, an innovative air vehicle that showcases the benefits of CycloRotor technology and its 360-degree thrust vectoring capabilities, all within a compact, passenger-oriented design.

Drawing on 15 years of technology development, extensive wind tunnel testing, and experience from over 500 flights of its technology demonstrator, the CruiseUp concept is designed to meet the individual air mobility needs expected to emerge in the coming decade. The vehicle promises to unlock new possibilities for everyday activities, enabling comfortable, simple, and safe transportation while also promoting sustainability by replacing pollution-intensive ground-based transportation.

CruiseUp uses CycloRotors as its electric propulsion system. This system is unique because it encapsulates the moving parts, providing an extra layer of safety for both the environment and the two passengers.

One of the biggest companies invested in AI is OpenAI, the father of ChatGPT. Reportedly, the company is taking matters into its own hands and is looking into making an in-house AI chip. The company may also be mulling over the acquisition of a chip company so that it has a steady supply of custom chips, as per a report by Reuters.

Nearly three decades later, the Apache’s status as the world’s premier attack helicopter remains largely unchallenged.

Here’s What You Need to Remember: The latest AH-64E Guardian model boasts uprated engines, remote drone-control capabilities, and a sensors designed to highlight muzzle flashes on the battlefield below. The Army has also experimentally deployed Apaches on U.S. Navy ships and had them practice anti-ship missions, and even tested a laser-armed Apache.

Early in the morning of January 17, 1991, eight sleek helicopters bristling with missiles swooped low over the sands of the An Nafud desert in as they soared towards the border separating Saudi Arabia from Iraq.

Tinkerers, developers, and general-purpose nerds will be happy to hear that Raspberry Pi CEO Eben Upton was wrong about the Raspberry Pi 5. When asked about the foundation’s fifth-generation single-board computer late last year, Upton said we should not expect to see it in 2023. But surprise, the Raspberry Pi 5 is launching this month with a big performance boost and a reasonable price.

The new model, which will be much faster, starts at just $60 with 4GB of RAM.

A new public database built from the ground up by Washington State University undergraduates looks to expedite scientific understanding of how skin heals.

The website — skinregeneration.org — was created for researchers but allows anyone to cross-compare information on more than 33,000 genes from different species as they relate to skin development, wound repair, and regeneration. Ultimately, it could help scientists reprogram adult skin for regeneration during wound healing and to inhibit the aging process.

“Historically, one of the major mechanisms scientists communicated through was with physical papers published in journals. A new concept of how to output knowledge is to create webtools in association with online manuscripts. For example, webtools that allow for interacting with large genomic datasets that have so much knowledge that cannot fit into a single paper. You can just interact with the data on any device and at any time you want,” said Ryan Driskell, head of WSU’s Fibroblast and Skin Regeneration Laboratory.

Mobility impairments such as those caused by cerebral palsy make it hard for people to perform even simple tasks like drinking a sip of water.

Gary Lynn, a Houstonian living with the condition, turned to Rice University’s Oshman Engineering Design Kitchen (OEDK) for help making the idea of an assistive-drinking device a reality. Rice undergraduate engineering students Thomas Kutcher and Rafe Neathery rose to the challenge, and the result is RoboCup ⎯ a robotic device that enables people with limited mobility to stay hydrated without help.

“We wanted to make it possible for people with cerebral palsy or similar mobility challenges to drink water autonomously rather than needing to rely on caregiver assistance,” said Kutcher, who is a bioengineering major. “The device is designed for wheelchair users who might have trouble holding a cup, and our hope is that it will grant users greater freedom.”

Aug 29 (Reuters) — Britain’s state-run national health service will be the first in the world to offer an injection that treats cancer to hundreds of patients in England which could cut treatment times by up to three quarters.

Following approval from the Medicines and Healthcare products Regulatory Agency (MHRA), NHS England said on Tuesday hundreds of eligible patients treated with the immunotherapy, atezolizumab, were set to have “under the skin” injection, which will free up more time for cancer teams.

“This approval will not only allow us to deliver convenient and faster care for our patients, but will enable our teams to treat more patients throughout the day,” Dr Alexander Martin, a consultant oncologist at West Suffolk NHS Foundation Trust said.
