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.

Upgrade Your 3D Printer with Klipper: A Complete Setup Guide
Klipper is a 3D printer firmware that moves motion planning off the printer’s microcontroller. The work runs on a Raspberry Pi or similar single-board computer instead. You get faster print speeds (300-500mm/s on a tuned Voron), pressure advance for cleaner corners, input shaping to kill ringing artifacts, and live config changes with no re-flashing. Klipper paired with a Mainsail or Fluidd web UI on a Raspberry Pi 5 is now the default stack for serious 3D printing.
30W Solar Raspberry Pi Server: Off-Grid Setup
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.
Gemma 4 Architecture Explained: Per-Layer Embeddings, Shared KV Cache, and Dual RoPE
Gemma 4 shipped on April 2, 2026 with four model variants under the Apache 2.0 license. The 31B dense model ranks third on the Arena AI text leaderboard with a score of 1452. The 26B MoE model scores 1441 while firing only 3.8B of its 26B total parameters per forward pass. So what design choices make this possible? Three of them break from the standard transformer recipe: Per-Layer Embeddings (PLE), Shared KV Cache, and Dual RoPE. Each one shifts the math for inference cost, memory use, and fine-tuning. The rest of this post covers those three, plus the Mixture-of-Experts layer and the multimodal encoders.
Home Assistant Smart Irrigation: Local Control, $25-89 Hardware
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.
PCIe Bifurcation: Add 4 NVMe Drives for $25-50 per Adapter
PCIe bifurcation splits one physical PCIe x16 slot into several independent x4 (or x8) logical slots. That lets you fit two to four NVMe drives on one cheap adapter card, often just $20 to $50 for a passive model. Bifurcation is a CPU-level feature, not the job of an extra chip, so each drive gets its own lanes with zero overhead. A Gen4 x4 link delivers around 7 GB/s per drive , the same bandwidth as a standard motherboard M.2 slot. Out of M.2 slots but still have a free x16 PCIe slot? Bifurcation is one of the cheapest ways to add more NVMe storage.
