This guide benchmarks SD card performance in CircuitPython across a range of boards, card tiers, and filesystems. The findings are straightforward: SDIO for bulk transfers, SPI for fast small writes. For max performance, pair a card over 32 GB (A2/U3 rated) with an exFAT filesystem. Read more at SD Card Performance in CircuitPython

More and more people are yearning for simpler devices. While some see older tech as less convenient, others see the singular function as focused. This radio project from trwmato on GitHub will give you old-fashioned radio listening with some modern updates;  without the existential threat of an endless doomscroll:   Raspberry Pi Zero project that […]

Are you curious why a clicky Pen… clicks? How a Zippo Lighter flips open? Or what lives inside a Pez Dispenser? The Mechanical Pencil website by Bryan may be for you. I’ve illustrated tear-downs and break-downs of everyday products that you may have taken for granted. Let’s take a look inside and understand how they […]

AkiraOS is Artur Founder’s Zephyr-based embedded OS that runs sandboxed WebAssembly applications on microcontrollers. The core idea: separate the OS from the application. The firmware stays stable. Apps are .wasm binaries — isolated, portable, and deployable over-the-air without touching the OS. Your App (C/C++/Python) → compile → app.wasm → SecureDeploy → runs on device OS unchanged Why this […]

The Global Positioning System (GPS) relies on its primary L1 frequency to broadcast precise timing and orbital data, allowing receivers on Earth to calculate their exact location. Because the L1 C/A signal transmits at just fifty bits per second, every bit of this navigation data must earn its place. Yet, within this highly constrained signal, […]

Architecture Diagram Generator uses Claude.ai with a special skill to generate professional architecture diagrams in seconds. Describe your system, and Claude creates a beautiful, dark-themed diagram as a standalone HTML file one can open in any browser. You can use it to scan an existing codebase, list your components, or ask for a typical architecture […]

It’s that time of year when I start planning my annual visit to Coney Island. My kids will be 6 soon and, for the first time, they will be old enough for a late afternoon/evening visit. I love Coney Island at night – the weather is just a little bit cooler, the crowd just a […]
