Linux 6.16 Release – Main changes, Arm, RISC-V, and MIPS architectures

Linus Torvalds has just announced the release of Linux 6.16 on LKML: It’s Sunday afternoon, and the release cycle has come to an end. Last week was nice and calm, and there were no big show-stopper surprises to keep us from the regular schedule, so I’ve tagged and pushed out 6.16 as planned. It’s worth noting that the upcoming merge window for 6.17 is going to be slightly chaotic for me: I have multiple family events this August (a wedding and a big birthday), and with said family being spread not only across the US, but in Finland too, I’m spending about half the month traveling. That means that I will try very hard to get most of the merge window done the first week before my travels start, and I already ended upgiving a heads-up on that to the people who tend to send me the most pull requests.

$12 WLED controller board supports WS2812 RGB LED strips

“xcrhom WLED Type-C” is a tiny ESP32 board designed to run WLED open-source firmware that supports WS2812(B) RGB LED strips. It also supports audio-reactive effects using an “external microphone”, which appears to mean the microphone on the smartphone running the WLED app, more on that later. We had already written about other small ESP32/ESP32-S3-based WLED controllers with the likes of Adafruit Sparkle Motion Stick and ANAVI Miracle Emitter, and the xchhom board’s main selling point is its price, as it goes for about $12 before taxes (AliExpress even shows me a $6.14 “Welcome offer” including shipping). xchome WLED Type-C board specifications: Wireless module – ESP32-WROOM-32D SoC – Espressif ESP32-D0WD dual-core Tensilica LX6 processor @ 240 MHz Storage – 32Mbit SPI flash Connectivity – Wi-Fi 802.11 b/g/n up to 150 Mbps, Bluetooth 4.2/5.x LE IPEX antenna connector (antenna provided) RGB LED support 3-pin connector with GND, DA (Data), and 5V signals […]
