A robust BME280 forced-mode loop starts one conversion, waits for the status register’s measuring bit to clear, then reads the compensated result. Fixed delays hide oversampling-dependent timing.

CodeQL 2.27.2 adds language models and queries, but two migration issues deserve attention: traced compiled-language builds on newer macOS/Xcode combinations and a rewritten Go CFG API.

The SPH0645 sends 18 bits of microphone precision inside a 24-bit I²S word. Wrong slot, edge or sign alignment can look like low level, clipping or noise.
SPH0645 I²S Audio Looks Wrong? Align the 18-Bit Sample Before Changing Gain Read More
APDS9960 gesture events can repeat or disappear when firmware clears the interrupt without consuming the gesture FIFO. Read status, drain valid datasets, then finish the engine sequence.

Arduino marked one year of UNO Q on October 8. Current documentation shows why the board differs from a conventional UNO: Debian runs beside a Zephyr-based real-time MCU.

BNO055 calibration is four separate 0–3 states. Save offsets only after system, gyroscope, accelerometer and magnetometer all report 3 in the intended operating mode.
BNO055 Calibration Status: Save Offsets Only After All Four Values Reach 3 Read More
AS5600 angle problems often start with magnet geometry, not software noise: check detection, too-weak and too-strong status before filtering 12-bit readings.
AS5600 Angle Jumps? Check Magnet Status Before Filtering the Data Read More
Raspberry Pi Desktop for PC and Mac now uses 64-bit Debian Trixie, supports persistent USB boot and installation, and includes Raspberry Pi Connect.

A free-space quarter-wave is about 17.3 cm at 433 MHz and 8.2 cm at 915 MHz, but feed point, ground, enclosure and legal band limits still determine the installed RFM69 antenna.

The PolyDryer Box XL targets 3 kg spool storage with sealed filament feed-through, humidity monitoring, and optional Dry Dock support. TVG evaluates the engineering promise, ecosystem costs, and tests that matter.
