Linux 6.17 release – Main changes, Arm, RISC-V, and MIPS architectures

Linux 6.17 has just been released on LKML: No huge surprises this past week, so here we are, with kernel 6.17 pushed out and ready to go. Below is the shortlog for just the last week – not the full 6.17 release – as usual. It’s not exciting, which is all good. I think the biggest patch in there is some locking fixes for some bluetooth races that could cause use-after-free situations. Whee – that’s about as exciting as it gets. Other than that, there’ the usual driver fixlets (GPU and networking dominate as usual, but “dominate” is still pretty small), there’s some minor random other driver updates, some filesystem noise, and core kernel and mm. And some selftest updates. This obviously means that the merge window for 6.18 will open tomorrow, and I already have four dozen pull requests pending. Thanks to the proactive people – you know who […]

XIAO Smart IR Mate Review – A compact smart infrared remote control hub for Home Assistant

SeeedStudio sent us a tiny Smart IR Remote hub for review: XIAO Smart IR Mate, or XIAO IR Mate for short. At first glance, it looks like any other WiFi IR blasters, but what makes it interesting is that the device is built on an open architecture using the XIAO ESP32C3 module and runs on ESPHome, working natively with the Home Assistant open-source home automation platform. As usual, SeeedStudio gives access to the source code, so it’s super convenient if you want to tweak the functions yourself to fit various needs. For those who are new to Smart IR, it’s a device that acts as an infrared (IR) control hub. The idea is to let you control legacy IR-based devices (old TVs, air conditioners, stereos, etc.) via a Smart Home system. We did several tests with several devices we had lying around, namely a Hatari oscillating fan, a Dyson blade-less […]

Blackout Comms Cluster – A pre-configured off-grid LoRa texting and GPS system with cryptographic security

Designed by Altware Dev Shop in the US, the Blackout Comms is an off-grid, LoRa-based encrypted mesh communication system built around ESP32 for texting and GPS location sharing without the need for any cellular networks or internet. The device uses asymmetric encryption and digital signatures for secure communication during blackouts, emergencies, or in remote areas where connectivity is unavailable. The device seemed a little bit pricey at first, but the complete kit includes two customized T-Deck communicators and one Altware Link/Node, all pre-configured and ready to use. Each communicator features a DFRobot GPS, Adafruit DS3231 real-time clock, 5000 mAh battery (≈48-hour runtime), external antenna, and PETG printed case, while the Link/Node integrates its own GPS, RTC, 3000 mAh+ battery, and antenna for cluster support. The system forms a private cluster with encrypted, frequency-hopping communication, signed delivery confirmations, and distributed mesh caching. Beyond messaging and location, it also supports proximity/motion sensing […]

M5Stack Stamp-S3A WiFi and BLE IoT module benefits from optimized antenna design, lower power consumption

M5Stack Stamp-S3A, also known as M5StampS3A, is an update to the M5Stamp S3 ESP32-S3 module introduced in 2023 with an optimized antenna design, lower power consumption, a larger user button, and a different logic for the RGB LED control. Other features remain the same with 8MB Flash, RGB LED, input button, and 23 GPIOs all in a tiny 26 x 18mm form factor. Two versions are available: the Stamp-S3A without pre-soldered headers and the Stamp-S3A PIN1.27 with headers soldered on the board and an orange heat-resistant cover. M5Stamp-S3A specifications: WiSoC – Espressif Systems ESP32-S3FN8 CPU Dual-core 32-bit Xtensa LX7 microcontroller with AI vector instructions up to 240MHz RISC-V ULP co-processor Memory – 512KB SRAM Storage – 8MB flash Wireless – 2.4GHz WiFi 4 (802.11b/g/n), Bluetooth 5.0 LE + Mesh Connectivity 2.4 GHz WiFi 4, 20 MHz and 40 MHz bandwidth, IEEE 802.11 b/g/n protocol, up to 150 Mbps Bluetooth 5, […]

HackLED Pro LED controller – An Adafruit Sparkle Motion alternative with WS2812 and RGBCW LED support

HACK Lab HackLED Pro is an Adafruit Sparkle Motion-like LED controller that runs a custom version of WLED and supports both WS2812 and RGBCW LEDs, making it ideal for DIY lighting projects, smart home setups, and audio-reactive light displays. Built around an ESP32 MCU, this board includes 2-way WS2812 LED outputs, 5 PWM channels (RGBCW), and an onboard silicon microphone for music reactive LED setup. Like the Sparkle Motion, the outputs of this board are level-shifted, and there’s also a power switch that toggles the output power between 5V and 12V. The board features a USB-C port with a PD controller, with which you can power and program the board. The controller is housed in a thermally protected 3D printed case and is also compatible with the generic version of the WLED firmware. HackLED Pro specifications: Wireless module – ESP32-WROOM-32E-N4 WiFi and Bluetooth module with 4MB Flash LED Control 2x […]
