We commend the research team behind this demonstration and look forward to continued collaboration with them and others to facilitate this kind of research. In order for anyone to have ever been affected by this, they would have had to use their car’s web browser and be served malicious content through a set of very unlikely circumstances. This demonstration wasn’t easy to do, and the researchers overcame significant challenges due to the recent improvements we implemented in our systems. While the risk to our customers from this type of exploit is very low and we have not seen a single customer ever affected by it, we actively encourage research of this kind so that we can prevent potential issues from occurring. UPDATE: A Tesla spokesperson reached out to provide this statement regarding the hack and related research: By working closely with this research group following their initial findings last year, we responded immediately upon receiving this report by deploying an over- the- air software update (v. What we’re seeing here will likely be the new normal in the future a never- ending arms race between hackers and companies, with security protocols made and broken, over and over, until we evolve into beings of pure orgone energy or the heat death of the universe, whichever comes first. The team managed to get control over both the Model X’s CAN bus (the overall internal network connecting the car’s electronic systems) and the ECU, for lower- level control. It’s notable that the lights that blink on and off are controlled independently this isn’t just sending signals to blink an indicator or turn on the low- beams each individual lighting sub- unit is controlled independently. Other things, like the bonkers light show set to music, are new, and show the degree of control they’ve managed to get over the car. Sure, it was harder, but the research team broke through, and produced this video showing what they accomplished: Some of what they managed was similar to what had been accomplished last year, just on the Model X and defeating the code signing security. Tesla introduced a system of firmware code signing in an attempt to prevent future similar hacks as Tencent Keen Labs just proved, those efforts just weren’t good enough. What’s especially notable is that after their demonstration of the Model S hacks in 2. After discovering similar vulnerabilities in the Model S last year, the Chinese security research firm Tencent Keen Security Lab have turned their attention to the Tesla Model X, and have been able to exploit these security holes to remotely do things to the Model X like open its doors, blink the lights, control in- car displays, and, most worryingly, actuate the brakes while the car is in motion.

Talking about this Chinese ham radio transceiver requires a veritable flurry of acronyms: HF, SSB, QRP, and SDR to start with. Of course, canned applications are great, but if you get one of these, you are going to want to try GNU Radio.Ĭontinue reading “TRX-Duo Is A Red Pitaya Clone For Software Defined Radio” → Posted in Radio Hacks Tagged Red Pitaya, sdr, software-defined radio You can do a lot more with a transmitting SDR - having both transmit and receive opens up many new projects. However, for something comparable, you will pay more for the Red Pitaya and - depending on capabilities - perhaps a lot more, although you do get more capability for the increased price. You can get a less capable Red Pitaya model for about $100 less than the going price. It was, however, able to hear the world easily. Using the box as a WSPR beacon, it was heard fairly well given the low output power. The device shows a browser menu with various options and the result is quite impressive. One has a number of applications that run on the device and will also run on a Red Pitaya. The board boots off an SD card and there are several to choose from. Connectivity: Ethernet and USB connectivity (WiFi with a dongle).CPU: Zynq SoC with a dual-core ARM Cortex A9.The device is pretty powerful compared to a cheap software defined radio: Sure, you can pick up an RTL-SDR dongle for a fraction of the price, but then you miss out on transmitting. While this unit isn’t inexpensive, it also isn’t as expensive as some of its competitors. obliges with a review of the Red device in the video below. Hello Sir Please close your firewall when you install it, the software is safe and will not cuase harm to your computer.Īnyways, turns out the USB cable uses a rip-off CH340.If you’ve noticed the TRX-DUO software-defined radio transceiver, you might have wondered how it stacks up to other choices like Red Pitaya or HackRF. When I challenged them, this was their response: USB Cable Driver DO NOT USE the driver that Retevis gives you. When I finally got past Amazon's failed message delivery, I realized why Amazon was blocking it. They kept trying to send me a DOCX file with instructions on how to download. I purchased a cable off Amazon and the seller was utterly incompetent. It took me quite a bit of back and forth to figure out where the programming software for the RB16/RB615 radios is. Posting it here so that future amateur radio enthusiasts can find this on Google searches. TLDR No need to upvote or anything (edit: thanks for the generous downvotes though!). New 160MHz-capable routers offer both – greater capacity and coverage. You want a router that can deliver better Internet speed to more devices and at greater distances. Coverage & Capacity-Wi-Fi speed is one piece of the puzzle.A faster connection results in faster Wi-Fi speeds. Speed-New Wi-Fi technologies deliver data more quickly than previous generations. Here are some additional terms you need to know about Wi-Fi connections: We’ll show you below how to determine the Wi-Fi generation on your device. 1 And since Wi-Fi speed is often related to internet connection range, there are a few ways to help improve performance throughout your home. Innovations like the recent giant leap to Wi-Fi 6 technology make today’s Wi-Fi nearly 3x faster than previous generations. With millions of users with wireless devices connecting to Wi-Fi around the world, it’s no wonder that people want to know how to improve their Wi-Fi speed for better experiences with entertainment streaming, large file uploads and downloads, and wireless gaming. Or your web browser keeps spinning without loading the page you want. Wi-Fi speed-you probably don’t think much about it until the movie you’re streaming crashes. If you don’t need to modify the lessons and just want a solid tool that helps kids learn, the JumpStart series, Reader Rabbit and ClueFinders all offer accessible lessons - even though they’re a bit dated.Īlthough using edutainment in the classroom isn’t a new concept, it does seem like, going forward, games like Minecraft will play a larger role in students’ learning. Moreover, Roblox allows users to create their own content by employing a coding language called Lua - a straight-forward system that has both drag and drop options as well as the more advanced feature of letting users embed their own lines of code. Much like Minecraft, it places a lot of power in the players’ hands, allowing them to create and problem solve. One of the most important things to understand about Roblox is that it’s not necessarily a game, but an online game-creation platform that hosts pretty much every type of game imaginable. As a teacher, you can modify the game to your liking, much as you would a regular lesson plan. Minecraft: Education Edition is relatively easy at the start, but it can be as complex as you’re willing to make it given time. The built-in lessons provide clear objectives for the students teachers can even create their own tasks for students to complete.Īll of this said, Minecraft helps players build problem-solving skills - they’re given a puzzle and, using the course materials, must solve it - as well as social skills, thanks to the game’s collaborative elements. Most importantly, Minecraft: Education Edition teaches students by connecting with their interests and then layering in those educational elements. Teachers and educators are able to tweak the game as they see fit or even create something useful that comes to mind. Unlike other educational games from the ‘90s and early 2000s, Minecraft: Education Edition is more of a tool than a purpose-built lesson. Theoretically, the game can be used to teach any subject, either as the main lesson plan or as supplemental material. “Please switch off your devices and stow them away, we’d love to see your smiles aiming our way.” We want to see your lovely faces and happy smiles!” “Please turn off your cameras and devices until after the ceremony. “The bride and groom request the joyful sight of your smiles, without the distraction of electronic devices.” “The greatest gift you can give us today is to be truly present, so please turn off all phones and cameras and enjoy this special moment with us.
