I explain microcontroller firmware that emulates candlelight using layered, low-resource random waves and simple integer math. I cover color gradients, LED mapping (WS2812B), and flicker modulation so constrained boards can produce organic light. If this interests you, please read the full post for code and details.

I solved stray light hitting my pet-feeder's fill sensors by filling 3D-printed slots with black, low-viscosity epoxy. Using a syringe I achieved a nearly flush, cleanable surface that keeps measurements accurate. Read the full post for materials, step-by-step photos, and a short demo video if you'd like to try it.

I’ve published a simple firmware example for the Always-On project, built for PlatformIO and Visual Studio Code with my HAL adapted for Adafruit Feather M0. It explains the hardware mapping, motion-triggered lighting behavior, and timing options. Please read the full post for setup instructions and the GitHub link.

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'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.
