Understand what a bootloader does in embedded Linux systems: DDR initialization, kernel loading, device tree setup, bootargs configuration, and system recovery. Essential knowledge for board bring-up, system porting, and firmware upgrade design.
Complete guide to the MPU6050 6-axis IMU: MEMS accelerometer + gyroscope working principles, I2C minimum circuit, register map, sensitivity scaling, complementary filter for attitude estimation, common pitfalls (sleep mode, 5V damage, gyro bias calibration).
Deep dive into MRTD (Minimum Resolvable Temperature Difference) vs NETD, spatial resolution, and MTF in thermal imaging systems. Why high-end infrared systems use MRTD for real-world target recognition capability — essential for defense, surveillance, drone payloads, and long-range monitoring.
Complete guide to Supervision, an open-source Python computer vision toolbox by Roboflow. Covers object detection, dataset format conversion (YOLO/COCO/Pascal VOC), video tracking with ByteTrack, zone counting, and building a real-time video analysis system with under 100 lines of code.
Georgia Tech student Tomas Salvo built ‘Reaper’ — a 5kg carbon-fiber RC plane with 250N turbojet — in his dorm room. Claims 500mph speed, Elon Musk reacted, and Boom Supersonic offered $100K prize for first amateur supersonic RC plane.
Building a 3D-printed Titan Comet fixed-wing UAV: common mistakes in printing, assembly, dual-motor wiring, CG balance, and pitot tube installation. From 5-day print to stable 30+ flights with detailed build specs and flight data.
Deep dive into cross-band asynchronous transceiver architecture for UAV-to-ground MESH networks: why splitting TX (500-700MHz) and RX (1300-1500MHz) with 1T2R design outperforms same-frequency systems in range, stability, and platform constraints.
Complete ISP debugging guide for RK3576 MIPI Camera: BLC, LSC, AWB, CCM calibration, 3DNR, sharpening, Gamma, 3D LUT tuning, IQ file deployment, and common issue troubleshooting for embedded vision systems.
