I designed a simple three-part 3D printed enclosure for the Adafruit PowerBoost 1000C and up to a 1200mAh LiPo. In this post I share the print files, component list, and step-by-step assembly tips to convert the board into a safe portable power pack — please read on if you'd like to build one.

I recently built 'Always-On', a minimal bidirectional mains-to-Feather bridge combining a power sensor and solid-state relay for safe home-control prototypes. I outline design choices, safe firmware testing without mains, and housing tips. If you're exploring a similar controller, read the full post for a practical starting point.

I built a compact Neopixel-based candlelight decoration with a DS3231 RTC and share the schematic, firmware, and build tips here. It's best placed behind a screen or in a jar. Read the full post for parts, assembly photos, and configuration notes to recreate it yourself.

I provide a complete event-loop firmware example for SAM‑D boards (Arduino Zero, Feather M0). I explain module design—Buttons, Display, and a support library—initialisation and polling logic, and link the source and demo. If you're curious, read the full post for code and implementation notes.

I built a simple, modular CMake-based toolchain for Adafruit Feather M0 boards that reuses Arduino tools while giving full build control. It’s aimed at prototype work and HAL development on macOS and Linux. If you’re curious, read the full post for setup steps and examples.

I ran a five-day long test of my plant watering sensor and the results were confusing, so I started a new, more insulated setup using an Adafruit Feather M0, an optocoupler, and pulse-length encoded signals with interrupts. If you’re interested in the hardware and code details, read the full write-up.

I built a compact logger to collect long-term capacitive readings from my plant watering sensor. Using a Feather M0, RTC/SD FeatherWing and a tiny OLED, it logs averaged frequency to CSV every minute so I can study watering-to-dry cycles. Read on for parts and details.

I've published a guide for the Five Light Spheres project — a quiet, artful winter decoration built with NeoPixels that blends colors across five spheres. I walk through materials, assembly, and code so you can recreate it at home. Read the full project page for details and photos.

I recently built a simple, budget-friendly table light from an IKEA candle holder using a NeoPixel ring and an Adafruit Trinket. I walk through parts, wiring, and the ready-made software with 50 color and animation modes. Read the full project page if you'd like to build one.

I'm concerned my archived documents could absorb moisture in a root cellar with 75–90% humidity, so I built a DIY data logger to monitor conditions inside sealed boxes. I walk through parts, breadboard-to-stripboard assembly, tests and a wiring diagram — please read the full post for the complete build.
