Yocto Project 6.0 “Wrynose” released with Linux 6.18 LTS

The Yocto Project 6.0, codenamed “Wrynose”, has just been released with Linux 6.18 LTS, about two years after Yocto Project 5.0 “Scarthgap” release with Linux 6.6 LTS. Over 240 contributors submitted over 4000 commits since the previous Yocto 5.3 “Whinlatter” minor release of the popular framework used to create custom embedded Linux distributions. Yocto Wrynose is a Long Term Support (LTS) release, which will be supported until at least April 2030. The project’s developers especially highlight these 4 years of support, improved SBOM and CVE tracking features, and more secure defaults to ease compliance with the upcoming EU Cyber Resilience Act (CRA). Yocto Project 6.0 highlights: Linux kernel 6.18 LTS Toolchain updates: GCC 15.2, glibc 2.43, LLVM 22.1, Go 1.26, and Rust 1.94. New bitbake-setup tool to fetch layers and setup build directories. Support for BitBake configuration fragments, which can be managed with the new bitbake-config-build command. This enables better […]

Clawdmeter – A DIY ESP32-S3 desk dashboard for Claude Code token usage monitoring

Clawdmeter is a DIY ESP32-S3-powered desk dashboard that displays Claude Code token usage on a 2.16-inch AMOLED screen so you know when you’re about to reach the limits in real time. It’s mostly a firmware project since it relies on off-the-shelf hardware (Waveshare ESP32-S3-Touch-AMOLED-2.16). It leverages the LVGL library for its graphics user interface, the NimBLE stack for Bluetooth LE (BLE) communication, and also functions as a HID keyboard for shortcuts using the buttons from the unit. We previously covered Waveshare ESP32-S3-Touch-AMOLED-1.8 with a 1.8-inch display, but never the 2.16-inch variant, so let’s have a quick look at the hardware first. ESP32-S3-Touch-AMOLED-2.16 specifications: Wireless MCU – Espressif Systems ESP32-S3R8 CPU – Dual-core Tensilica LX7 @ up to 240 MHz with vector instructions for AI acceleration. Memory – 512KB RAM, 8MB PSRAM ROM – 384KB Connectivity – 2.4 GHz WiFi 4 and Bluetooth 5.0 LE Storage 16MB NOR flash MicroSD card slot […]
