Want to bring your 433 MHz RF devices into your smart home? This guide shows how to flash the Sonoff RF BridgeR2 with ESPHome, allowing full Home Assistant integration. From hardware prep to YAML configuration, you’ll learn to receive and send RF signals—enabling automations and extending your smart home to legacy remotes and sensors.
Want solar production data in Home Assistant without spending a fortune? I built a DIY pulse counter using an ESP32 and IR sensor to read pulses from my parents’ smart meter—no high-voltage wiring needed. With ESPhome and Home Assistant integration, plus solar forecasts via Solcast, this project turned their legacy solar system into a smart, connected setup.
I’ve been spending a lot of my spare time continuing to hone my artistic drawing skills with Drawabox. I’ve almost completed lesson two, and here’s my results thus far: Thinking in 3D The task here was to draw arrows and forms that appear to exist in a 3D space on a 2D surface. Texture and…
After 10 years of loyal service, my Saeco Incanto coffee machine began shutting off mid-brew. A teardown revealed a burnt bridge rectifier—likely caused by water damage. With a €1.50 replacement part, a bit of soldering, and some maintenance upgrades (new seals, crema valve, and more), the machine is now restored and brewing like it’s brand new.
I’ve been giving learning how to draw an earnest new attempt. Currently, I’m on box 210 of 250 boxes of the drawabox 250 box challenge. It’s mind-numbingly hard sometimes to push through. Someone compared it to “artistic push-ups”. And that’s what it feels like. I’ve been doing this for over a month now, about 5–10…
Frustrated with flimsy Ikea desks, I built my own wooden workbench—spacious, sturdy, and tailored to fit both my PC and electronics projects. This detailed DIY guide walks you through materials, tools, design plans, and step-by-step instructions, including sanding, finishing, and gluing the tabletop. It’s a satisfying, long-lasting upgrade you can build yourself—even in a small flat.
Car AC systems can harbor mold and bacteria—causing bad smells and potential health risks. This hands-on guide shows how to disinfect your evaporator coil yourself, using a spray cleaner, some basic disassembly, and smart use of the cabin and drain hoses.

Portable air conditioners are easy to use but deeply flawed. Most rely on a single exhaust hose, causing hot air to be pulled back into the room. This guide explains why that happens and how a simple DIY dual-hose conversion—using duct tape, carton, or 3D-printed parts—can drastically improve efficiency and performance, even with cheap models.
After nearly finishing my first CAD semester, I designed and 3D printed a custom cable holder for my parents’ Kärcher SC3 steam cleaner. It solves a real-world nuisance with a clean, snap-in solution using existing attachment points. The result: a simple, functional print that fits perfectly—and marks my first personal success in functional CAD design.
