Hardware

The Orange Pi 5 Plus is the better self-hosting board for Docker-heavy workloads thanks to its 8-core RK3588 CPU, up to 32GB RAM, and dual NVMe M.2 slots. The Raspberry Pi 5 wins for beginners and single-service setups with its superior software ecosystem and community support. Both boards draw under 18W, run Docker containers on ARM64 without issues, and can be purchased for under $200 in their mid-range configurations. The right pick depends on how many services you plan to run and whether hardware expandability or software polish matters more to you.

On Wayland with GNOME 46+ or KDE Plasma 6.1+, each monitor gets its own scale factor. A 4K center display at 200% and side 1080p monitors at 100% work without trade-offs. X11 still hurts here. The whole desktop shares one scale, so one display always looks wrong. If old Linux DPI pain has kept you on a single monitor, the 2026 Wayland stack has caught up.

Why Mixed DPI Is Hard

The typical developer setup pairs a 27" 4K center monitor (163 PPI) with one or two 24" 1080p side panels (92 PPI). That’s nearly a 2x pixel density gap. The OS has to draw UI elements at different sizes on each screen.

Yes, you can build a working outdoor weather station for under $100. You need an ESP32 running ESPHome (current stable: 2026.3.x), a Davis 6410 anemometer for wind, a tipping-bucket rain gauge, and a VEML6075 UV sensor. All of it reports live data to Home Assistant over WiFi. The result is hyperlocal weather data more accurate than any commercial forecast for your yard, roof, or field.

Hardware Selection and Sensor Wiring

The backbone of this station is an ESP32-S3 DevKitC (or the older ESP32-WROOM-32). The S3 variant has better WiFi range and BLE 5.0 support if you want to expand later. Power it with a 5V USB-C supply. For longer outdoor cable runs, use a 12V barrel jack feeding an LDO voltage regulator. The same board family fits other outdoor builds too. Our guide to tracking particulates with a PMS5003 node uses a similar power and enclosure setup.

Can your consumer router do WireGuard VPN at 800 Mbps, isolate IoT devices into separate VLANs, and kill bufferbloat with a single queue management setting? Stock firmware almost certainly cannot. OpenWrt can.

OpenWrt is a full Linux distribution that replaces the limited manufacturer firmware on compatible routers. The router ends up behaving more like a managed switch and enterprise firewall than the box your ISP sent you. The current stable release is OpenWrt 25.12.2 (March 2026), which introduced the apk package manager (replacing opkg) and now supports over 2,200 devices. Flashing typically takes five minutes and is reversible if you keep a backup.

Picking Between Three Incompatible Low-Profile Worlds

Touch typists who want the most familiar desktop feel in a slim chassis should reach for Cherry MX Low Profile 2.0 . Its 3.2mm travel and 45gf actuation keep the tactile vocabulary of full-size MX intact, and it accepts standard MX-stem keycaps. Competitive gamers chasing the shortest travel win with Gateron KS-33 or Gateron Low Profile 2.0: 3.0mm travel, a 1.3mm actuation point, and a linear 45gf spring weight, shipping on boards like the Keychron K5 Max and NuPhy Air75 V2 . Custom-build enthusiasts soldering ergonomic splits such as the Corne, Ferris Sweet, or Ploopy Adept should buy Kailh Choc v2: it is the only switch in this trio that fits 18x17mm Choc-spaced PCBs while accepting MX-profile keycaps, something neither Cherry nor Gateron can offer on those boards.

For most developers wanting hands-on RISC-V in 2026, the StarFive VisionFive 2 at $65 for the 8GB model is the most practical entry point. It runs Debian 13 (Trixie) on the JH7110 quad-core SiFive U74 at 1.5GHz, ships with an Imagination BXE-4-32 GPU that now has mainline Mesa Vulkan drivers, supports Docker and NVMe via kernel 6.6+ LTS, and delivers roughly 60-70% of a Raspberry Pi 4’s single-threaded speed. That gap is smaller than you might expect when the goal is learning RISC-V toolchain internals. The ecosystem here has matured enough that you spend time writing code, not fighting drivers.
