When Software Cannot Fail: The Hidden World of Open-Source Operating Systems in Space, Defense, and Safety-Critical Machines
Most people never think about the software keeping airplanes in the sky, satellites alive in deep space, or nuclear sensors monitoring radiation levels under mountains. But embedded systems engineers do. Because in these environments, embedded systems development doesn’t get a second chance. A single bit-flip can cost a mission. A stalled thread can crash a satellite. A missing watchdog reset can turn a $5 million drone into a falling brick. We live in a world surrounded by

The Silent Infrastructure of the Future: Open Power Electronics Tools Behind EVs, Fast Chargers, and AI Datacenters
When you read news about electric vehicles , AI datacenters , or renewable energy systems , the focus is usually on batteries, compute power, or sustainability. Almost nobody talks about the one engineering discipline quietly enabling all of it — high-voltage embedded systems development and power electronics design . Every EV charger, solar inverter, GaN server supply, and AI power stage depends on switching devices handling thousands of volts and tens of kilowatts — operat

How Industries Can Use Open-Source Audio & Vibration Analytics to Predict Machine Failures Before They Happen
Subtitle: A practical guide for factories, OEMs, and industrial automation teams to implement low-cost, high-impact condition monitoring using sensors, DSP, and edge AI. A New Reality: Machines Fail Silently Before They Break Every rotating machine—pumps, motors, gearboxes, HVAC blowers, spindle drives—emits a signature. Before a bearing cracks, vibrations increase. Before a gearbox fails, harmonics shift. Before a pump leaks, noise spectra change. Traditionally, condition mo

🌍 Global IoT Connectivity – Regional Adoption, Spectrum, and Protocols
The Internet of Things (IoT) is a global phenomenon . But unlike the internet, where TCP/IP creates a near-universal layer, IoT connectivity remains fragmented by region . The reason is simple: Spectrum regulations differ across countries. Telecom operator strategies vary. Industry ecosystems have evolved differently. Proprietary protocols and legacy systems remain entrenched in some markets. The result? A logistics tracker built for NB-IoT in China may not work in the US, w

🏭 Part 6: Industrial & Mission-Critical IoT – Wireless HART, ISA100, DECT-2020 NR, and TETRA
Most IoT deployments focus on convenience, efficiency, and cost savings. But in industrial and mission-critical environments – oil rigs, chemical plants, power grids, defense, and emergency response – the stakes are much higher. Here, downtime can cost millions, and failures can risk human lives . These environments demand ultra-reliable communication, deterministic performance, strong security, and resilience to interference . This is where industrial and mission-critical I

⚡ Part 5: Wired & Optical IoT – Ethernet, KNX, Fiber, and PLC
When people think of IoT, they often imagine wireless sensors scattered everywhere . But in reality, some of the most reliable and mission-critical IoT deployments still rely on wires – whether it’s twisted pair, Ethernet cables, optical fiber, or even the power lines themselves. Why? Because wires offer stability, bandwidth, security, and power delivery in one channel . For environments like factories, smart buildings, utilities, and heavy industry , wired and optical IoT t

📡 Part 4: LPWAN & Sub-GHz IoT – LoRa, Sigfox, Mioty, DASH7, and Proprietary Bands
When we think of IoT at city-scale, agriculture fields, utility grids, or industrial campuses , we need networks that can connect devices spread over kilometers while still keeping power consumption ultra-low . This is where LPWAN (Low Power Wide Area Networks) and sub-GHz technologies shine. They fill the gap between short-range protocols (BLE, ZigBee, Wi-Fi) and cellular IoT (NB-IoT, LTE-M, 5G) by offering: Long-range coverage (1–15 km, sometimes more). Ultra-low powe

🌐 Part 1: The Big Picture – IoT Communication Technologies Landscape
IoT (Internet of Things) is not just about smart sensors and connected devices. At its core, IoT is about communication — how billions of devices exchange data reliably, securely, and efficiently. Without the right communication technology, IoT is just “things” without the “internet.” But here’s the challenge: there is no single best protocol for IoT. Instead, we have a broad landscape of technologies — each with its own strengths, weaknesses, and use cases. From short-rang
