SmartMediaKit adds MP4 recording to real-time audio/video pipelines: push-side and pull-side recording, shared capture/encode resources, H.264/H.265 reuse, file segmentation and cross-platform integration.

ELRS explained: how LoRa modulation, dynamic frequency hopping and forward error correction deliver 2-4ms latency, and how ELRS 2.4GHz compares with SBUS and CRSF for FPV drones.

Stealth coatings in 2025: how absorption budgets work, why broadband and low-emissivity demands conflict, and why the real competition has shifted from reflection loss in dB to coating service life.

A practical guide to MPU6050 zero drift and jitter: static calibration, DMP init failures, thermal drift, low-pass filtering, angle wrap-around and why Yaw drift cannot be fully eliminated without a magnetometer.

FlowPilot, a dual-stream World-Action Model from BIT, predicts future depth and generates smooth Bernstein trajectories, running under 18ms on a Jetson Orin NX for 5.5 m/s agile drone obstacle avoidance.

A fast steering mirror does not control angle, it controls optical-axis error. Aomway explains the closed loop behind nanometer-scale laser pointing: piezo actuators, capacitive/PSD/interferometric sensors and high-speed control.

WarpMPC from RWTH and MIT solves thousands of MPC problems in batch on one GPU, reaching 250k SQP iterations per second and generating 20M control samples in about two minutes to train a drone controller.

Sound source localization (DOA) errors are usually a microphone phase alignment problem, not an algorithm problem. Aomway explains why a 35mm array spans only ~5 samples at 48kHz and how to keep channels sample-aligned.

Learn how to back up and restore ArduPilot flight controller parameters before flashing firmware: export the .param file, screenshot key values, and record the firmware version. Aomway explains the 3 must-dos plus the post-flash recalibration steps.

esp32flight turns a $15-35 ESP32-S3 touchscreen board into a standalone desktop flight radar—no Raspberry Pi, server, subscription, or API keys. Tracks 80 aircraft within 250nm, 5 views including retro CRT, ntfy.sh emergency squawk alerts, MQTT/Home Assistant integration, OTA updates, and an Android APK version.
