Linux 6.2 has just been released with Linus Torvalds making the announcement on LKML as usual: So here we are, right on (the extended) schedule, with 6.2 out. Nothing unexpected happened last week, with just a random selection of small fixes spread all over, with nothing really standing out. The shortlog is tiny and appended below, you can scroll through it if you’re bored. Wed have a couple of small things that Thorsten was tracking on the regression side, but I wasn’t going to apply any last-minute patches that weren’t actively pushed by maintainers, so they will have to show up for stable. Nothing seemed even remotely worth trying to delay things for. And this obviously means that the 6.3 merge window will open tomorrow, and I already have 30+ pull requests queued up, which I really appreciate. I like how people have started to take the whole “ready for [...] The post Linux 6.2 release – Main changes, Arm, RISC-V, and MIPS architectures appeared first on CNX Software - Embedded Systems News.

I don’t think I’ve ever written about open-source hardware headphones. But that’s precisely what Ploopy offers with an amplifier based on a Raspberry Pi RP2040, a Texas Instruments PCM3060 24-bit DAC, and an amplifier circuit, as well as 3D printed parts and open-source firmware written in C. As we’ll see further below the project is reasonably well documented, and you can either build it from scratch, purchase a fully-assembled kit, or something in the middle. I suppose you could even do some knitting since woven covers are part of the build just in case making your own PCBs and 3D printing parts are not your things. The electronics are comprised of two boards: The Gould amplifier board with the Raspberry Pi RP2040, Texas Instruments PCM3060 24-bit 96/192 kHz DAC, and several TI OPA1688 audio operational amplifiers The Mazzoleni driver flex boards going into the left and right rings with a [...] The post Ploopy – 3D printed open-source hardware headphones feature Raspberry Pi RP2040 MCU, TI PCM3060 24-bit DAC appeared first on CNX Software - Embedded Systems News.

Purism has just announced the Lapdock kit to turn their Librem 5 Linux smartphone into a laptop with a 13.3-inch touchscreen display thanks to the NexDock 360 laptop dock. I was a big believer in mobile desktop convergence around 10 years ago, expected to be soon able to use my phone as a computer or laptop with a dock, and it looked like it might have become a reality when Canonical launched the Ubuntu Edge smartphone crowdfunding campaign in 2013. But it turns out demand was not sufficient, and Canonical eventually ended their convergence efforts focusing on profitable IoT and cloud segments instead. But that does not mean there isn’t a niche market and Purism’s Lapdock kit addresses it to some extent. The Lapdock kit is comprised of three parts namely the NexDock 360 laptop dock, a magnetic mount to attach the Librem 5 to the side of the NexDock [...] The post Purism Lapdock kit converts the Librem 5 Linux smartphone into a laptop appeared first on CNX Software - Embedded Systems News.

“Block after Block” has designed a dual-display tabletop retro-gaming console using plywood edge grain and a Raspberry Pi 400 keyboard PC that allows players to physically face each other during a fight or other gameplay. While there’s a galore of projects based on Raspberry Pi SBCs, the Raspberry Pi 400 keyboard PC is more like a consumer product due to its form factor, but Block after Block integrated the PC into its own retro-gaming console which involved a lot of woodworking skills and installing RetroPie on the Pi 400 device. This DIY project mostly involves spending time in a workshop cutting wood, and once you’re done with this part, it should be pretty straightforward. The following items are required for the project: A Raspberry Pi 400 keyboard PC Two monitors (second-hand monitors will do) An HDMI splitter to mirror the output from the Pi 400 along with a micro HDMI [...] The post Raspberry Pi 400 powers dual-display retro-gaming console appeared first on CNX Software - Embedded Systems News.

Heata, which began as an innovation project with British Gas, is a UK company that connects a server to your hot water cylinder and provides hot water to the house master for free up to 4.8 kWh per day, and at least 2.5 kWh as per contractual obligations. Companies spend millions of dollars to cool the servers hosted in their data centers and most of that heat is completely wasted. So Heata decided to create a win-win solution that lowers their cooling cost and provides free hot water to whoever has their server installed in their house. The installation process is said to be tested and approved by British Gas so you don’t lose your hot water cylinder warranty, and the heat transfer mechanism is patented as well under the UK patent GB2576035. A technician would come to cut the insulation and attach a thermal bridge to the cylinder.

Banana Pi has started selling an inexpensive 2.5Gbps SFP to RJ45 adapter for their Banana Pi BPI-R3 WiFi 6 router board that goes for $17.89 plus shipping ($25 shipped here) on Aliexpress. The BPI-R3 router includes five Gigabit Ethernet RJ45 ports as well as two 2.5GbE SFP cages, but since not everybody has equipment that takes SFP cables, they used to sell it with a $30 TP-Link adapter. The company now appears to have found a cheaper model marked “SFP-2.5G-T” module that works with their board. It’s designed to be inserted into one of the 2.5GbE SFP cages and provide a more common 2.5GbE RJ45 port to the user. There’s very little information about the module except its designed with an up to 100-meter cable, and the serial number BT2211010016 only points to Banana Pi’s Wiki. But I don’t think the company designed its own adapter and found another Wiki [...] The post 2.5Gbps SFP to RJ45 Ethernet adapter sells for $25 shipped appeared first on CNX Software - Embedded Systems News.
