I walked through designing and 3D-printing a 70 cm PETG planter for my deep-rooted Ctenanthe. I share the tests, design choices, and practical fixes for warping, filament, split parts, and assembly. If you’re curious about large-scale prints or want the model files and tips, please read the full post.

I built a 100×80cm 3D‑printed artwork and walk through the technical steps I used: preparing mathematical height data, generating Z‑maps, slicing into printable tiles with Blender and PrusaSlicer, and assembling and painting the final piece. If you're curious about the scripts and workflow, read the full tutorial.

In Part 3 I print three enclosure panels and the rotary turntable for my 3D-printed cat/pet feeder. I share the STL files, PETG print settings, and notes on warping and difficulty. If you're following the series or planning your own print, read the full post for detailed tips and links to the turntable guide.

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’m building a small utility called the Swiss-Precision Timer and just received prototype 37x18mm two-layer boards from PCBWay. They’re populated with tiny SMD parts I plan to reflow using a stencil. The project is still a prototype — I’ll share assembly notes and updates once I solder the first version. Please read on.

I guide you through building a compact particle sensor node using a Raspberry Pi Zero W and a minimal custom shield, with published Gerbers, STL files and example code. I keep the design simple and extendable—if you'd like to build your own networked air-quality node, read the full post for parts, assembly and setup.

I wrote a concise page about my Snowflake project from late 2017, sharing open-source hardware designs and base firmware. If you have some electronics experience, you can build your own boards — it's a rewarding decoration. Read the full project page for files, repo links, and leave any feedback or questions.

I take you through part two of my cheap plant-watering sensor project, testing a prototype: power draw, LED impact, oscillator and MCU startup timing, voltage-divider checks, firmware inputs, and PCB preparation. If you want to see the detailed measurements and next steps, I invite you to read the full post.

I've just finished Part 2 of the Outmoded Sequencer project, sharing the journey from prototype to final device. I explain the custom PCB work, lessons learned (including unreliable steel-ball matrix switches), and practical recommendations. If you're curious, please read the full post for build tips and cautions.
