Hands-on tutorials and guides across robotics, embedded systems, hardware, software, frameworks and cybersecurity.
Cybersecurity
A zero-to-expert guide to securing Modbus projects on microcontrollers. Learn the protocol, understand its attack surface, design a defense-in-depth architecture, harden register access and firmware, and build a practical ESP32 Modbus TCP device with strict validation and a Python client.
Electronic Hardware
A complete zero-to-expert engineering guide to transforming a technology product idea into a functional, validated, manufacturable, and market-ready prototype — covering requirements, feasibility, architecture, electronics, firmware, mechanics, prototyping, verification, cost, compliance, security, DFM, testing, and pr
Communication protocols
A complete, ground-up guide to the Serial Peripheral Interface: how the four wires really work, what CPOL/CPHA mean, how to design robust SPI buses, and a full buildable Arduino master/slave project with working code on both sides.
Embedded Systems
A complete zero-to-expert Raspberry Pi tutorial covering hardware, power, Linux, networking, GPIO, camera interfaces, Python, Picamera2 and OpenCV, ending with a practical real-time computer-vision inspection project.
Embedded Systems
Know nothing about IO-Link? This complete guide covers it end to end — point-to-point SDCI (IEC 61131-9), the C/Q line, COM speeds, wake-up, process data vs ISDU parameters, events, IODD, Data Storage, and how a master bridges to a PLC or the cloud — and finishes with a full bidirectional project: a sensor device that
Electronic Hardware
One of the hardest problems in high-speed PCB design is routing a reliable memory interface between an FPGA and DDR3. This complete guide covers it end to end — SSTL-15, signal groups, fly-by topology, termination, stackup and impedance, BGA fanout, length/skew matching, return paths, crosstalk, PDN, timing budget, SI
Electronic Hardware
A complete, practical guide to Texas Instruments C2000 real-time control MCUs on the TMS320F280039C — ePWM, PWM-synchronized ADC, dead-time, closed-loop digital power control, Trip Zone protection, HRPWM and the CLA — with five buildable DriverLib projects.
Frameworks
Know nothing about Zephyr? By the end of this deep, complete masterclass you will understand it like a professional — West, CMake, Kconfig and Devicetree, the kernel, threads, drivers, subsystems, connectivity and testing — and you will have written and built real Zephyr firmware yourself.
Embedded Systems
Never heard of Zigbee? By the end of this guide you will understand it completely — device roles, mesh routing, the stack, clusters, security and battery life — and you will have built a real, working Zigbee sensor network whose data flows into MQTT.
Robotics
Know nothing about ROS 2? By the end of this guide you will understand it properly — nodes, topics, services, actions, QoS, workspaces, launch files, tf2, URDF and the big stacks — and you will have built and run real ROS 2 nodes in
Communication protocols
Know nothing about EtherCAT? By the end of this in-depth guide you will understand it completely — the "processing on the fly" idea, frame structure, masters and slaves, distributed clocks, the state machine, mailbox protocols, safety and diagnostics — and how to build a real EtherCAT network.
Embedded Systems
The complete, practical guide to Industrial IoT — from sensors and the ESP series to protocols, edge computing, data, security and predictive maintenance. By the end you will understand the entire IIoT stack and have built a real, connected industrial node yourself.
Embedded Systems
Know nothing about OPC UA? By the end of this guide you will understand it deeply — servers, the address space, nodes, subscriptions and built-in security — and you will have built a real, working OPC UA server and client in Python, ready for industrial use.
Embedded Systems
Know nothing about MQTT? By the end of this guide you will understand it deeply — brokers, topics, QoS, retained messages, security — and you will have built a real, working project with command-line tools, Python and an ESP32.
Frameworks
The microcontroller and platform you pick at the start quietly decide what your project can become. A complete dissection of how to choose them so that future growth stays open — from requirements and headroom to ecosystem, portability and supply chain.
Robotics
Humanoid robots are no longer science fiction. Advancing them is not a vanity project — it answers real pressures of demography, dangerous work and economics, and it pushes the whole field of engineering forward.
Software
An embedded device gets a machine online — but it is the software above it that monitors, controls, stores the data and predicts failures before they happen. Here is how that software layer really works, end to end.
Embedded Systems
From hardware roots of trust and cryptography to TLS, secure firmware updates, key management and IEC 62443 — a deep, practical dissection of how to make embedded communication genuinely secure, from zero to expert.
Robotics
Humanoid robots are moving out of the lab and into workplaces and homes. Interacting with them well is part psychology, part engineering — and it is fast becoming a skill none of us can ignore.
Embedded Systems
From RS-485 and Modbus to CAN, OPC UA, MQTT and cellular IoT — a deep, practical guide to every layer of embedded communication, and the proven ways to make a decades-old machine speak to your network.
Embedded Systems
Most factories still rely on machines built long before the internet. Embedded systems are the fastest, most cost-effective way to give that legacy equipment network connectivity, remote control and real-time monitoring — without replacing it.
Communication protocols are rules that define how devices exchange data with each other.
