This article explains embedded communication protocols (UART, I²C, SPI, USB) that enable hardware components to exchange data reliably. It provides hands-on Arduino projects and foundational concepts like bits, clocks, and signal formats needed to understand how modern devices communicate.
FeeTech's STS3215 servo has factory-default ID=1, making it impossible to distinguish multiple servos on a daisy-chained bus. Engineers discovered a race condition vulnerability that allows selective targeting of individual servos, enabling ID assignment without disconnection. They developed utilities for servo diagnostics, repair, and rapid recalibration during arm assembly.
Documentation for installing Debian 13 (trixie) on a Synology DS115j NAS with Marvell Armada 370 processor. The project provides a self-contained UART and TFTP installation kit with boot artifacts and rootfs payload, including detailed guides for initial setup, recovery procedures, and hardware-specific configurations like fan control and LED behavior.
