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 show a simple, reliable method I use to assemble MicroMaTch connectors with a hammer. I made a short video that walks through the exact technique step by step. If you want a quick, practical demo and tips, I hope you'll watch the clip and read the brief how-to.

I wanted to capture the tiny, spiky corona of light from a snowflake decoration on video and found it challenging. After experiments I developed a simple effect that better conveys the sparkling as seen by the eye. Read on to see my approach, results, and how you can try it yourself.

I've been making videos of my LED snowflake decorations, but they still fall short of the live sparkle and diffraction I see. I explain the problems—blinding LED peaks and weak diffraction spikes—and invite you to read the post to watch the clips and see my plan to add digital effects.

I added a stable Hitachi LCD driver to the HAL layer, using an MCP23008 backend to cut wiring and simplify hardware. This post walks through parts, firmware repositories, and how to run the demo via serial shell. Read the full article for setup steps, code links, and usage tips.

I share a quick video of the snowflake assembly, showing the LED-side assembly with hot-air soldering. The build went smoothly overall, though some excess solder left a few LEDs slightly raised. If you're curious about the process and tips, I invite you to watch the full post and video.

I recently finished a compact cat feeder and made small upgrades — I added a USB charging port and a larger battery so it can run for months. I put together a short demo video and linked the project notes; if you’re curious, please watch the clip and read the full write-up.

I tested 13 SMD LEDs for my plant-watering sensor project, soldering them to a small board and driving them from an Arduino Zero Pro to compare brightness and flash styles. I share photos, part numbers and a short demo video — read on if you’d like the full results and notes.

I made a short video showing how I soldered Boldport's Touchy, an SMD board with a tricky chip. I admit I had a loose soldering tip early on and share what I learned. If you're interested, please watch the full video and check the board photos in the post.

I made a short video soldering the Boldport Project "Tap" and testing the PCBite PCB holder. I walk through the key steps, tool setup, and positioning tips so you can see how the holder performs. If you're curious, watch the full clip and follow along with the post.

I made a short live demo of the Outmoded Sequencer and added some audio effects at the end so you can hear its real sound. The video shows occasional connection quirks (a brief tap usually fixes them). I’d love your thoughts — watch the demo and stay tuned for part two.

I recently assembled the final Outmoded Sequencer PCB and documented the soldering in a short video. I accidentally cut a bottom trace and repaired it with a jumper wire; the magnet matrix now secures the steel balls. I'll finish tone tuning and add four resistors — please watch the video and read on for details.
