Discover the egg-crate phased array — an origami-inspired, additively manufactured antenna from Georgia Tech that combines physical folding with RFIC beam steering to synthesize near-limitless radiation patterns for 5G, mmWave, automotive radar, and satellite applications.

After accidentally burning a $1,000 robotics platform, Julia learned ROS2 Jazzy in 8 hours using pure software: turtlesim, nodes/topics/services, packages, mcap recording, and Raspberry Pi cross-device control. A complete beginner-safe ROS learning route.

QL-X930H is an industrial video OSD character overlay module compatible with AHD/CVBS surveillance. One module handles encoder length measurement, multi-channel counting, analog acquisition, and MODBUS-RTU RS485 sensor data with on-screen real-time overlay.

OSUG is an open-source underwater glider that uses a 3D-printed hull, Atmel-based autopilot, and a homemade buoyancy engine to navigate underwater for weeks. Explore its features, build route, and use cases for marine science, aquaculture, and environmental monitoring.

FusionCore is an open-source ROS 2 localization project that fuses GNSS, IMU, wheel odometry, radar, and visual SLAM into a continuous 100 Hz pose using a 23-state UKF. Learn its architecture, engineering wins, limitations, and how to evaluate it with your own rosbag data.

A close reading of a 2026 arXiv paper presenting a reproducible multi-physics simulation framework for HPM counter-UAS design: 2.45 GHz propagation, coupling, sigmoid damage models, and 10,000-trial Monte Carlo kill-probability analysis.

How to architect control + vision + embedded fusion systems: 6-layer decomposition, latency and jitter in vision closed loops, edge vs MCU division, communication reliability, and safety design.
