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.

Don’t be fooled by flashy IMU datasheets. The 6 metrics that truly matter: noise density (μg/√Hz), bias stability (°/hr), temperature drift (°/s/℃), range, bandwidth (≥1kHz), and post-shock bias change. Includes field-tested thresholds, 3 real failure cases (¥800,000 loss), and a printable selection checklist for industrial drone flight controllers.

How to track infrared drones at just 3-10 pixels where AI fails completely. Multi-frame energy accumulation + motion trajectory modeling: traditional IR detection as safety net, Track-Before-Detect (TBD) for weak targets, Kalman/particle motion trackers, and a staged 3-tier strategy (<10px / 10-30px / >30px) for counter-drone systems.

QuadRF is an open-source 4×4 MIMO SDR module that gives everyone ‘electromagnetic X-ray vision’—visualizing WiFi through walls, tracking DJI Mini drones via 5GHz control signals, and AR overlays of the RF world. $499 plug-and-play kit with preloaded SD card, plus EME moon-bounce and phased-array research applications.

Boeing’s ULCS (Ultra Low-Cost Seeker) unveiled August 11, 2026: an active radar seeker built from commercial off-the-shelf components to slash missile seeker costs. Modular open architecture, four summer 2026 test rounds, and the broader US defense industry shift toward ‘affordable mass’ solutions.

A hands-on tutorial on PX4 flight log analysis with ULog format and Flight Review tool. Four real-world cases: vibration diagnosis via FFT, EKF anomaly detection, power supply issues, and PID tuning problems. Plus Python + pyulog automation scripts for batch production-line log analysis.

A complete PaddleDetection-based pipeline for small-object UAV detection and tracking: PP-YOLOE-SOD detection, OC-SORT/ByteTrack tracking, trajectory smoothing, motion prediction, and gimbal aiming control. Includes tracker parameter tuning, ROI focusing, EMA smoothing, PID control, and RTX PRO 5000 performance benchmarks.

Confused by RC receiver protocols? This guide breaks down SBUS, PPM, iBus, and CRSF with refresh rates, channel counts, latency, and wiring tips. Learn which protocol fits aerial photography drones, racing quads, and lightweight 3D-printed builds—with real flight experience from F450, MARK5, and micro drone setups.

Peking University researchers present JitTrack, a motion-aware Transformer tracking framework that stabilizes multi-object tracking under violent viewpoint jitter in agile UAV flights. Three modules—SQR, MAR, and MIDT—natively adapt to drone 3-axis camera motion, achieving 38.4% MOTA on VisDrone2019-MOT and 68.1% IDF1 on UAVDT with real-flight validation.

Step-by-step tutorial: connect the TDK InvenSense ICM-45686 6-axis MEMS IMU module to an Arduino UNO via SPI. Learn wiring diagrams, library installation, Polling_SPI example code, and how to read accelerometer, gyroscope, and temperature data in real time.
