Tom's Hardware ☛ Maker builds Raspberry Pi-powered temperature gun using a Pico 2
There are all sorts of handy tools out there, and a handful of them can be made from scratch with a Raspberry Pi. No one knows this better than maker and developer Arnov Sharma who's using our favorite SBC to power this custom-built temperature gun. To save on power, he's opted to use the latest Raspberry Pi Pico 2 microcontroller.

The Register UK ☛ Raspberry Pi launches a CM4 for colder temperatures
A cynic might point out that the Raspberry Pi 4 hardware can generate more than enough heat on its own with a sufficient workload; most of the components on the board will also happily run in the broader range already. However, Samsung's extended-temperature-range SDRAM and eMMC parts are required to ensure functionality at lower temperatures.

Tom's Hardware ☛ Chinese government shifts focus from x86 and Arm CPUs, gov't promoting RISC-V chips heavily
China is set to introduce new policies promoting the nationwide use of open-source RISC-V chips, aiming to reduce its reliance on foreign technologies, such as x86 and Arm. The initiative was drafted by eight government agencies, including the Cyberspace Administration of China, the Ministry of Industry and Information Technology, the Ministry of Science and Technology, and the China National Intellectual Property Administration. Once enacted, it will mark the first official government push for RISC-V adoption in China. The upcoming policy could be announced as early as this month, though the exact release date remains uncertain.

Tom's Hardware ☛ This Raspberry Pi Snake console totally bites — in a good way
Retro gaming on the Raspberry Pi is one thing, but programming a game from scratch is another. This project, however, put together by maker and developer Arnov Sharma, does both. Using our favorite SBC, he's created a handheld console for playing the classic game Snake, fixed up with custom 3D-printed housing.

Raspberry Pi ☛ How we added interlaced video to Raspberry Pi 5 DPI
The very first Raspberry Pi had a composite video output, and all models with a 40-pin header have a display parallel interface (DPI) output. With some external components, DPI can be converted to VGA or RGB/SCART video. Those analogue interfaces are still in demand for retro media and gaming.
