I often use a simple oscilloscope trick to debug time-critical code: toggle an I/O line before and after critical sections and observe interrupt timing and execution width. It’s low-effort and revealing — read on for practical steps, examples, and tips to measure and reason about your timing issues.

I finally published all design files and documentation for my plant watering sensor project. The package includes PCB layouts and firmware, but this is an advanced build: it needs SMD reflow, Atmel Studio and an Atmel-ICE programmer. If you're interested, please read the full post and the GitHub repo for details.

I've finished testing a flat storage box set for 3D printing and adjusted the label profile so they stack neatly with regular boxes. I designed them to save drawer space for rarely used parts. Read the full post for stacking details, label geometry, print settings, and download links if you'd like to try them.

I built a simple, single-portion programmable cat feeder in about four days using rapid prototyping. I describe the Fusion360 sizing, plywood shell, servo mechanism, electronics, and the issues I encountered with breakout boards. If you're curious, read the full post for parts list, wiring and source code.

I demonstrate SMD soldering in a short practice video, working through 1206 and 0805 packages and wrestling with tiny 0603 parts. If you’re curious about surface-mount techniques or improving your hand-soldering, watch the full video — I share what I learned and a few practical tips.

I guide you through evolving a simple Arduino blink example into a reusable event system. In Part 2 I cover function-pointer events, an EventLoop module, and practical multi-event examples. If you want cleaner, non-blocking firmware structure, read the full post for code and explanations.
