Honoring the Legends: The Pioneers of Wireless Networking, Cellular Technology, and Digital Logic

Published: September 14, 2026

The modern world of embedded systems, IoT devices, high-speed internet, and computer-aided chip design did not emerge overnight. It was built upon the groundbreaking work of a dedicated generation of engineers, researchers, and educators. Recently, the global engineering community bid farewell to several influential pioneers whose work fundamentally shaped the way we design hardware and communicate wirelessly today. From the shores of Hawaii where the first wireless data packets flew, to the Bell Labs facilities where cellular networks became a reality, we explore the lasting legacies of these extraordinary minds.

For modern developers working with Wi-Fi, ESP32 modules, or LoRaWAN, wireless data transfer is a fundamental building block. However, back in the late 1960s, computer networking was strictly tethered to copper cabling. That changed when Dr. Franklin “Frank” Kuo and his colleague, Norman Abramson, developed ALOHAnet at the University of Hawaii at M&amacr;noa.

The Paradox of Sovereignty: How Europe’s AI Ambitions Clash with Its Semiconductor Strategy

Published: September 07, 2026

The European Union finds itself at a critical technological crossroads. On one side, Brussels is aggressively pushing for artificial intelligence leadership, detailing plans for state-of-the-art data centers, national computing clusters, and specialized AI factories. On the other side sits a deeply entrenched vulnerability: the continent’s profound reliance on foreign semiconductor manufacturing. As Europe accelerates its digital infrastructure, it inadvertently highlights the stark limitations of its own chipmaking capabilities.

This structural friction is the core focus of the upcoming Chips Act 2.0, the European Commission’s planned revision of its flagship industrial framework. The original 2023 Chips Act set an optimistic target of capturing 20 percent of the global semiconductor production market by 2030. However, realistic industry assessments, including reports from the European Court of Auditors, suggest that the bloc will struggle to hit even 12 percent. To rectify these shortcoming, policymakers are pivoting their strategy, shifting from purely subsidizing production facilities to actively stimulating domestic industrial demand. Yet, this strategy faces a fundamental paradox: the very hardware required to build Europe’s AI future cannot currently be manufactured within its borders.

The European AI Paradox: Can Chips Act 2.0 Resolve the Silicon Dependency Trap?

Published: September 06, 2026

The European Union finds itself at a critical crossroads where its geopolitical ambitions directly clash with its technological realities. On one hand, Brussels is aggressively pushing for "technological sovereignty," aiming to secure the continent's digital future and reduce its reliance on foreign supply chains. On the other, the EU's massive, state-sponsored acceleration into artificial intelligence is creating an insatiable appetite for advanced silicon—hardware that Europe simply cannot produce. This inherent contradiction lies at the core of the upcoming "Chips Act 2.0," a sweeping revision of the European Commission’s flagship semiconductor strategy.

In 2023, the European Union introduced the original Chips Act with a bold milestone: raising Europe's share of global semiconductor manufacturing to 20% by the end of the decade. However, that target has been met with growing skepticism from industry analysts and public watchdogs alike. The European Court of Auditors recently warned that meeting this objective is highly improbable. Even the Commission’s own updated projections paint a more modest picture, estimating a market share of just 11.7% by 2030.

How to Change Raspberry Pi WiFi Details Directly from the SD Card

Published: September 04, 2026

It is a scenario familiar to every embedded system engineer, IoT developer, and hobbyist: you deploy a headless Raspberry Pi to a remote corner of your home or workspace, only to lose access when your network configuration changes. Perhaps you updated your router, changed your WiFi SSID, typed a typo into your configuration file, or took your project to a new location. Without a dedicated monitor, keyboard, and mouse, you appear to be locked out.

Fortunately, you do not have to format your microSD card and start your project from scratch. By accessing the filesystem on the SD card directly from a host computer, you can inject new WiFi credentials and restore your wireless connection. Depending on the version of Raspberry Pi OS you are running, the methods differ slightly, but they are all straightforward once you understand how the system boots and manages network profiles.

Reinventing Electromechanical TV: Build a Portable 4K-Wide Screen Using Raspberry Pi Pico

Published: September 03, 2026

In the pantheon of television history, the electromechanical systems of the 1920s often feel like a bizarre, steam-punk detour. Developed by pioneers like John Logie Baird, these early systems relied on spinning disks with spiral patterns of pinholes—known as Nipkow disks—to sweep a light beam across a viewing area. While quickly eclipsed by cathode-ray tubes (CRTs) in the 1940s, electromechanical television remains a fascinating frontier for modern hardware hackers, retro-tech enthusiasts, and embedded developers.

Today, electromechanical displays have found a second life among makers, embedded engineers, and retro-computing enthusiasts. While many recreate these systems as desktop-sized curiosities using vinyl records or large acrylic disks, a brilliant project called the Scanwheel demonstrates how modern technology can shrink this hardware into a pocket-sized form factor. By utilizing a 3D-printed drum instead of a disk, high-speed LEDs, and the powerful Raspberry Pi Pico, this portable device achieves an astonishing horizontal resolution of over 4,000 pixels on a 20-line display.

Harnessing RP2040 PIO to Build a Portable, High-Resolution Mechanical Television

Published: September 02, 2026

While modern display technology is dominated by ultra-thin OLED panels and high-refresh-rate LCDs, there is an enduring fascination with the electromechanical display systems of the early 20th century. What began as an exploration into unique digital clock designs has evolved into a fascinating engineering project: a pocket-sized, high-resolution mechanical television known as the Scanwheel. This unique DIY project achieves an astonishing horizontal resolution of 4,096 pixels across just 20 physical scan lines, demonstrating how modern microcontrollers can breathe new life into century-old concepts.

Traditional electromechanical televisions, popularized by pioneers like John Logie Baird in the 1920s, relied on a rotating Nipkow disk. This flat plate featured a series of small apertures arranged in a spiral pattern. As the disk spun, each hole swept across a light source, tracing a single horizontal scan line. By modulating the brightness of the light source in synchronization with the disk's rotation, a complete two-dimensional image could be formed due to the persistence of vision.

The European AI Paradox: Why the Drive for Sovereignty Runs on Foreign Silicon

Published: September 01, 2026

The European Union's quest for technological independence has hit a complicated roadblock. As Brussels pushes forward with massive initiatives to build regional artificial intelligence hubs, gigafactories, and hyperscale data centers, it is simultaneously accelerating a massive demand for the very hardware it cannot produce. The advanced processors required to drive these high-performance computing (HPC) nodes remain designed and manufactured thousands of miles away. This structural mismatch is at the heart of the upcoming European Chips Act 2.0, a planned policy revision aimed at resolving the critical flaws of the bloc's initial semiconductor strategy.

Passed in 2023, the original European Chips Act set an optimistic goal: doubling Europe's share of global semiconductor manufacturing to 20 percent by the end of the decade. However, reality has proven far more stubborn. The European Court of Auditors has already sounded the alarm, suggesting that this timeline is highly unrealistic. Current realistic estimates from the European Commission peg the bloc's future market share closer to a modest 11.7 percent.
