For most hobbyist PCB work, the Pinecil V2 at around $26 is the best value soldering iron thanks to its USB-C PD and QC3.0 power flexibility, RISC-V open-source firmware (IronOS ), and sub-10-second heat-up time. But the Hakko FX-888D (now succeeded by the FX-888DX at around $130-150) remains the superior benchtop station for marathon soldering sessions due to its thermal recovery and ceramic heater. The Miniware TS101 at roughly $50-70 splits the difference as a portable iron with an OLED display and dual power input that handles everything from SMD rework to through-hole joints with interchangeable TS-series tips.

Home Assistant Blueprints are reusable automation templates. They split the logic from the per-device bits. You define a pattern once, say a motion light with a timeout, then spin it up for every room by filling in a form. No YAML to copy. No ten near-twin automations to babysit. In Home Assistant 2026.4, blueprints span three domains: automation, script, and template. They ship dozens of selector types for clean input forms and tidy collapsible sections for bigger setups. They’re the fastest way to keep smart home behavior the same across many devices.

You can use HDMI-CEC commands through Home Assistant ’s HDMI-CEC integration - or a CEC-capable device like a Raspberry Pi running cec-client - to control TV power, input switching, and volume from automations and dashboards. Instead of juggling three or four remotes, you wire up a “Movie Mode” automation that dims the lights , powers on the TV, switches to the correct HDMI input, and sets volume to a comfortable level. One tap. Done.

The consumer SBC market in 2026 is not dead. It is just no longer what it was sold as. Raspberry Pi, Orange Pi, Rock Pi, and the rest of the single-board computer crowd now ship 70-80% of their units to industrial customers. Think factory automation, digital signage, point-of-sale terminals, and medical devices. The $35 computer that was meant to put a hackable Linux machine in every teenager’s bedroom is now more likely bolted inside a mall vending machine.

Yes, you can build a self-sufficient, portable Raspberry Pi server powered entirely by the sun - no mains power, no generator, no ongoing fuel cost. With a 30W solar panel, a 12.8V LiFePO4 battery, a charge controller, and a handful of systemd scripts, you can run a weather station, a mesh network node, or a local web server indefinitely from a fence post, a rooftop, or a field station. This guide walks through the math, the parts, and the software that make it work reliably rather than just technically possible.

A smart garden irrigation system on Home Assistant joins three parts: a Wi-Fi sprinkler controller, a rain sensor, and automations. The automations cancel or adjust watering based on rainfall, soil moisture, and the forecast. With the WiseWater integration and the native scheduler in Home Assistant 2025.12, this setup now beats pricey cloud-bound irrigation systems. Here is how to build one from scratch.

Why DIY Smart Irrigation Beats the Commercial Options

Commercial smart sprinkler controllers like Rachio , Orbit B-hyve , and RainBird Wi-Fi run $100 to $200. Their “smart” features all need a cloud link and often a paid plan. That includes weather skip logic, seasonal tweaks, and soil type awareness. If the vendor shuts down its servers (remember Wink ?), those features revert to dumb timer-only watering. You’re left with an overpriced relay board.
