QuadRF is a phased array antenna that can see WiFi through walls, spot drones in the sky... and it's powered by a Pi 5 and FPGA board. Very neat device, we have a full video up on Geerling Engineering...

Have you ever wondered how Starlink can keep talking to satellites moving across the sky? It uses a Phased-Array Antenna. It has many small antenna elements on a flat surface, and each one is given a tiny phase delay so the radio wave adds up in one chosen direction. That lets the beam steer electronically and stay locked onto a fast-moving satellite. In this animation, the beam pattern was generated using computational electromagnetics, by computing how the array’s directional pattern changes as those phases are updated.

Wifi signals can be used to see your body through walls. Using open source software and some cheap hardware, you can measure the disturbances in wifi waves emanating from a router. Those disturbances are measured and converted into body shapes to tell you where someone is in a room.

Australia News “We’re bombarded with a cocktail of chemicals from on high. Those white vapor trails in the sky left by aircraft, government weather modification cover up, and in the process we're all being slowly poisoned. Chemtrails are happening and that they are for climate engineering.” “We have NASA satellite imagery like that which you're showing right now that clearly no one knows, needs to know anything about meteorology to see that there's very unnatural patterns in those cloud formations. In fact patterns that nature cannot make.” “In addition to our testing of precipitation, the climate engineering components in the precipitation, aluminum, barium, strontium polymer fibers using a flying laboratory that NOAA national oceanic and Atmospheric Administration also uses, and we have just confirmed the same climate engineering elements that were emitted from aircraft in a layer that we flew through. We have film footage of these aircraft at altitude turning on and off. You can't turn condensation on and off with the nozzles visible as you see in that, in that particular image you're showing now, you can see the nozzles on the wings. We have up close photographs as well. If people don't believe what they see with their own eyes, I think there's not much we can show them.”

Are First Person View (FPV) Drones a wonder weapon? Not many platforms can take out Starlink, personnel, mortars, armored vehicles, antenna, and other Drones up to ranges of 20km like we see in this Russian video below, however there’s a bit more to the story as always 👇

“I want to take out a jet-powered Shahed head-on,” says Hero of Ukraine Hulk from the BULAVA unit of the Separate Presidential Brigade. We spent a night on duty with a soldier who is fully devoted to his mission and continues destroying enemy drones even while on leave. In the video, Hulk talks about new enemy tactics and demonstrates the Hornet Vision ecosystem by Wild Hornets in action — from interceptor STING drones to the revolutionary 360° antenna that is changing the tactics of this war. The full video featuring Hulk’s combat work and valuable experience is now available on our YouTube channel. Go watch it: 📹

Very excited to share this #openEMS simulation of a 60GHz #mmwave radar PCB! You can see how the e-field component is generated and then propagates in the transmission lines towards the antenna array. The radiated electric field shows one main lobe at 0 deg, and smaller side lobes #b3d #radar #kicad #electronics #educational hackaday #blender3d #antenna #rf Altium KiCad PCB FreeCAD (CAD+CAM+CAE) Jacques Lucke Chris Gammell #Physics #Engineering #Science

1/ From the very first day, we were promised that an #Ethereum node could run on any consumer device. In 2024, you can run on a $200 ARM64 board using ~10w: - 1 Archive node + a validator client - A Supernode (L1+L2 on the same device) This is called decentralization. +info👇

Elon Musk: It's important that engineers see the pain in the factory. “One of the things I like is just make sure that engineering and production are closely connected so that engineering is not like off in some ivory tower and can't see the problems on the production floor. When engineering is right here and you walk out and you see the production floor, you can actually see where you've designed something that is very difficult to manufacture. You can see the pain in the factory, where things aren't getting made. What's choking the production lines? We have the same thing in Hawthorne for Falcon 9 and Dragon.” Interview with Sandy Munro, May 29, 2025

Q: It's thought in the paddock that your car is actually the best chassis and if you can get that extra bit of power you are the ones to beat. So are you thinking if we can just get this [Engine ADUO] we know we have an incredible car? Lewis Hamilton: "Yes absolutely, I mean the guys at the factory have done an amazing job with the car and we still have improvements to make but the car is fantastic it's just it's a battle of development through the season obviously some people bring upgrades one weekend and others the other but yeah we're just at the mercy of the lack of power that we have and I know that everyone worked really hard on the engine and reliability is obviously is very good it's just when you're lacking that straight line speed against the Merc it's very very tough but nonetheless you know we have to expect that the rest of the season that's just the way it is so we'll just try and see if we can continue to add on to the car and try and close the gap if we can go through quicker through corners in some races maybe we can get closer to a challenge in front of us."

ELON: WE CAN BUILD A CITY ON MARS AND BE A MULTI-PLANET SPECIES... IT'S VERY EXCITING! “It's wild that this giant 250-ton object went to space, came back, and was caught by giant Mechazilla arms. It's super cool! That's the kind of thing that is inspiring and exciting. There's a lot of potential. I think we can actually build a permanently occupied science base on the moon. We can build a city on Mars. We can be a multi-planet species. And be out there among the stars. It's very exciting!” Source: Lancaster, Pennsylvania, October 2024

JAMES RICKARDS: Iran's 60% enriched uranium is not a bomb. Getting to 90%, weaponizing it, building a device, and mounting it on a missile that doesn't blow up in midair—that's years of engineering at best. We have time to strangle them financially, and that's exactly what we should do. James Rickards
