Always-On Intelligence Without the Cloud: Why it matters more than you think
Much of the AI conversation today is still focused on scale: larger models, more data, more compute. Embedded systems live in a different reality, where constraints are unavoidable, and efficiency is the priority. What’s emerging is not a smaller version of cloud AI, but a different approach altogether, the one that values locality, predictability, resilience, and trust. Always-on intelligence without the cloud isn’t just a technical milestone. It’s a change in how we think about where intelligence belongs.

Pay it Forward
A popular car bumper sticker reads, "If you can read this, thank a teacher!" I might say, "If you can read THIS (article on Embedded Related), then you've been blessed with great experiences and/or great educators or volunteers that got you excited about tech and helped you believe that you had a future in this field!" Why not pay it forward by helping other children have those same great experiences? As we enter another season of giving, I hope you consider doing what you can to support the hundreds or thousands of non-profit organizations, educators, and volunteers around the world who are getting kids excited about tech the same way YOU got excited about tech. In this article, I'll share with you a handful of organizations that I know of or donate to that have this mission. How do you like to give back?

C to C++: Templates and Generics – Supercharging Type Flexibility
"C to C++: Templates and Generics – Supercharging Type Flexibility" illuminates the rigidity of C when managing multiple types and the confusion of code replication or macro complexity. In contrast, C++ offers templates, acting as type-agnostic blueprints for classes and functions, which allows for the creation of versatile and reusable code without redundancy. By using templates, developers can define operations like add once and apply them to any data type, simplifying codebases significantly. Generics further this concept, enabling a single code structure to handle diverse data types efficiently—a boon for embedded systems where operations must be performed on varying data, yet code efficiency is critical due to resource limitations. The blog walks through practical applications, showcasing how templates streamline processes and ensure type safety with static_assert, all while weighing the pros and cons of their use in embedded software, advocating for careful practice to harness their full potential.

Embedded Developers, Ditch Your IDEs – Here’s Why!
Ditching your Integrated Development Environment (IDE) temporarily can be a transformative learning experience in embedded development. This post invites you to explore the underpinnings of IDEs by delving into alternative tools and processes like Makefile, CMake, Vim, GDB, and OpenOCD. Understanding these tools can demystify the background operations of IDEs, revealing the intricacies of compiling, linking, and debugging. This journey into the “under the hood†aspects of development is not just about learning new tools, but also about gaining a deeper appreciation for the convenience and efficiency that IDEs provide. By stepping out of your comfort zone and experimenting with these alternatives, you can sharpen your skills, enhance your knowledge, and possibly discover a more tailored and streamlined development experience. Whether you're a novice or a seasoned developer, this exploration promises insights and revelations that can elevate your embedded development journey.
Three more things you need to know when transitioning from MCUs to FPGAs
Take a look at three more important difference between FPGAs and MCUs: "code reuse" vs templating, metastability and blocking vs. non-blocking operations.
So You Want To Be An Embedded Systems Developer
This is a practical, boots-on-the-ground roadmap of books, videos, and inexpensive dev boards you can actually use to become an embedded systems developer. It contrasts hobbyist platforms like Arduino and Raspberry Pi with professional ARM-based evaluation kits, lists must-read resources for firmware, real-time systems, and testing, and emphasizes hands-on practice and the safety responsibilities of working with real-world devices.

Soft Skills For Embedded Systems Software Developers
Soft skills often determine whether an embedded project ships on time as much as technical chops do. This post lays out practical, engineer-friendly guidance on interpersonal skills, communication, time management, deep focus, asking for help, learning, and resilience. It mixes concrete tips like the documentation system, pomodoro and quiet hours with habits such as engineering notebooks and role-playing to make collaboration and productivity more reliable.
Review: Hands-On RTOS with Microcontrollers
Brian Amos's Hands-On RTOS with Microcontrollers delivers a practical path from bare-metal to full RTOS applications using FreeRTOS on an STM32 Nucleo-F767ZI board. The book combines clear explanations of concurrency, interrupts, and DMA with step-by-step toolchain setup and runnable examples that show building, debugging, monitoring, and scaling embedded systems for real projects and coursework.
Skills For Embedded Systems Software Developers
Embedded development demands a broad, practical skillset, and this post lays out the core knowledge employers expect across software, hardware, and tooling. It highlights essential languages like C, low-level concepts such as interrupts and RTOS, plus hardware skills like debugging with JTAG and using oscilloscopes. You also get realistic timelines, hands on study advice, and resource pointers to build a portfolio that proves you can ship reliable firmware.
Examining The Stack For Fun And Profit
Stack bloat can hide in short initialization paths, and this post walks through finding it with hands-on debugging. The author builds a tiny test program and uses gdb plus custom stack-helper scripts to scan, watch, and walk the stack. That process reveals getaddrinfo pulling in glibc DNS code that allocates large local buffers and uses alloca and PLT resolution, consuming roughly 11KB of stack.
Learning Rust For Embedded Systems
Rust eliminates whole classes of memory and concurrency bugs, making it a compelling choice for embedded projects, and the author recommends it for the VolksEEG project after a rapid evaluation. The post connects Rust fundamentals such as ownership and borrowing, RAII, traits, and unsafe blocks to familiar embedded patterns. It also provides a curated on-ramp of videos, books, and tools like Cargo, RTIC, and probe-rs to get hands-on quickly.
Levitating Globe Teardown, Part 1
Tim Wescott buys a $30 floating-globe desk toy and walks through first impressions, hands-on magnet experiments, and a frank critique of its control system. He highlights the toy's underdamped response, uni-polar electromagnet tradeoffs, and simple hacks that reveal clues about the pole pieces and magnet layout. This is a practical, engineer-forward preview before the actual teardown in part two.

This is a practical, engineer-forward preview before the actual teardown in part two.
Levitating Globe Teardown, Part 2
Tim Wescott opens up a budget levitating globe and shows why it seems magical: a massive 30 mm rare-earth magnet and a deliberately cheap magnetic circuit. He documents a bolt used as the flux core, a likely microcontroller and hall sensor in the head, very fine winding in the electromagnet, and a single-transistor unidirectional drive. Part 3 will measure forces and sensor voltages to build a better controller.
