[ad_1] Coolest controllers ever? Icy gamepads melt in users’ hands Arduino Team — July 8th, 2024 Nintendo’s Joy-Con controller system is very innovative and generally well-regarded, with one major exception: stick drift. That’s a reliability issue that eventually affects a large percentage of Joy-Cons, to the frustration of gamers. But what if that was intentional […]

[ad_1] The late 1990s saw the widespread introduction of solid-state storage based around NAND Flash. Ranging from memory cards for portable devices to storage for desktops and laptops, the data storage future was prophesied to rid us of the shackles of magnetic storage that had held us down until then. As solid-state drives (SSDs) took […]

[ad_1] [Thomas Scherrer] likes to tear down old test equipment, and often, we remember the devices he opens up or — at least — we’ve heard of them. However, this time, he’s got a Hung Chang HC-F100 multifunction counter, which is a vintage 1986 instrument that can reach 100 MHz. Inside, the product is clearly […]

[ad_1] Begun, the Spectrum Wars have. First, it was AM radio getting the shaft (last item) and being yanked out of cars for the supposed impossibility of peaceful coexistence with rolling broadband EMI generators EVs. That battle has gone back and forth for the last year or two here in the US, with lawmakers even […]

[ad_1] Conventional batteries have anodes and cathodes, but a new design from the University of Chicago and the University of California San Diego lacks an anode. While this has been done before, according to the University, this is the first time a solid-state sodium battery has successfully used this architecture. Sodium is abundant compared to […]

[ad_1] 8cc.vim is a C compiler that exists as pure Vimscript. Is it small? It sure is! How about fast? Absolutely not! Efficient? Also no. But does it work and is it neat? You betcha! Ever typed :wq to write the buffer and exit in Vim? When you do that, you’re using Vimscript. Whenever one […]
