[ad_1] You may have heard some scary news about RISC-V CPUs. There’s good news, and bad news, and the whole thing is a bit of a cautionary tale. GhostWrite is a devastating vulnerability in a pair of T-Head XuanTie RISC-V CPUs. There are also unexploitable crashes in another T-Head CPU and the QEMU soft core […]

[ad_1] Researchers demonstrate sustainable 3D printing by using poly(N-isopropylacrylamide) solutions (PNIPAM), which speedily and reliably turn solid by undergoing a rapid phase change when in a salt solution. This property has been used to 3D print objects by using a syringe tip as if it were a nozzle in a filament-based printer. As long as […]

[ad_1] Few processors have found themselves in so many different devices as the venerable Z80. While it isn’t powerful by modern standards, you can still use devices like this Cidco MailStation as a terminal. The MailStation was originally designed as an email machine for people who weren’t onboard with this whole computer fad, keeping things […]

[ad_1] Fluke meters have been around for a long, long time. Heck, we’ve got a Fluke 73 that we bought back in 1985 that’s still a daily driver. But just because they’ve been making them forever doesn’t mean they last forever, and getting a secondhand meter back in the game can be a challenge. That’s […]

[ad_1] From the “why didn’t we think of that” department comes [dupontgu’s] pong mouse project. The mouse appears and acts like a normal computer mouse until you click the scroll wheel. When you do, the mouse rapidly moves the cursor on the connected computer to play pong. Obviously, though, the paddles and the ball all […]

[ad_1] HVAC – heating, ventilation, and air conditioning – can account for a huge amount of energy usage of a building, whether it’s residential or industrial. Often it’s the majority energy consumer, especially in places with extreme climates or for things like data centers where cooling is a large design consideration. When problems arise with […]

[ad_1] [Ryan Miceli] wanted to build some reverse engineering skills by finding a new exploit for an original Xbox. Where he ended up was an exploit that worked across the network, across several games, and several different consoles. But it all started with an unbounded strcpy in Tony Hawk Pro Skater (THPS). Xbox, PlayStation 2, […]

[ad_1] Making fire detection more accurate with ML sensor fusion Arduino Team — August 8th, 2024 The mere presence of a flame in a controlled environment, such as a candle, is perfectly acceptable, but when tasked with determining if there is cause for alarm solely using vision data, embedded AI models can struggle with false […]

[ad_1] If there’s one thing humans love, it’s dancing with chance. To that end, [Jonathan] whipped up a fun dice box, connecting it to the Internet of Things for additional functionality. Expect dice roll stat tracking to become a big thing in the D&D community. The build is based around Pixels Dice. They’re a smart […]

[ad_1] Adjusting office chair height with simple voice commands Arduino Team — August 8th, 2024 A month ago, ElectronicLab modified his office chair with an electric car jack, giving it motorized height adjustment. That worked well, but required that he push buttons to raise or lower the seat. Pushing those buttons is a hassle when […]
