The iKuai IK-Q3000 is an AX3000 Wi-Fi 6 router (149 CNY) aimed at small offices and stores, supporting SD-WAN, multi-WAN, and flexible deployment modes. Performance tests showed 5GHz throughput of 964Mbps at 1m, 934Mbps through one wall, and 269Mbps through two walls; idle power consumption was about 3.5W. Teardown revealed an MT7981BA CPU, 512MB RAM, 128MB flash, and an MT7976CN RF chip with 3T3R for better coverage. This review offers practical data for evaluating the router’s speed, heat, hardware, and build quality.

The article shares a home network cabinet setup, listing hardware such as iKuai routers, 10G switches, a QNAP NAS, mini PC server, UPS, and multiple Wi-Fi access points. It describes wiring with Cat6a and fiber, plus an iKuai forum photo contest with prizes, offering readers equipment inspiration and contest participation details.

This article provides a beginner-friendly tutorial for building a personal blog website using Linux, Docker, 1Panel, and Halo. It explains domain registration, cloud server purchase (Hong Kong server avoids ICP filing), 1Panel and Docker installation, Halo deployment, theme/plugin customization, and HTTPS/SSL setup. No programming skills are required. The solution is containerized and open-source, supports HTTPS, and with a theme change can also serve as a corporate website.

The ACASIS TBU405Pro M1 Thunderbolt 4/3 M.2 enclosure paired with the WD SN7100 1TB SSD undergoes unboxing, teardown, and benchmarking. The dual-controller design (JHL7440 for Thunderbolt/USB4, RTL9210 for USB3) achieved sequential reads of 3164MB/s on a Mac mini via Thunderbolt and 974MB/s via USB 3.1. Notable features include a fan toggle, tool-free installation, and low thermals under load.

The article presents an open-source EG1164-based synchronous rectification boost converter module supporting 8–50V input, 8–60V adjustable output, and 219kHz switching. Test results show up to 97.3% efficiency and 287W output at 8A, with potential beyond 300W. It includes schematic, PCB layout, ripple measurements, and component purchasing guidance.

Using a Zhongchuang ET4410 LCR bridge, the author measured inductance, capacitance, Q/D, ESR, and reactance of various inductors and capacitors at 100Hz–100kHz. Iron-silicon-aluminum toroidal inductors showed peak Q at 10kHz; SMD inductors performed better at high frequency. Solid capacitors significantly outperformed electrolytics, with Rubycon best among electrolytics. Capacitance dropped after 10kHz for electrolytics, while monolithic capacitors had high low-frequency ESR/reactance. The article provides full data tables and a spreadsheet.

An open-source three-phase power meter for home energy monitoring uses three PZEM-004T modules with an ESP32-C3 running ESPHome, uploading voltage, current, power, power factor, and energy data to HomeAssistant over Wi-Fi. It measures 80–260V per phase, up to 100A, with 0.5% accuracy. Design files, firmware, and enclosure models are provided.

Migrating macOS to an external SSD on a 2024 Mac Mini avoids expensive Apple upgrades. The guide details formatting the drive as APFS with GUID Partition Map, creating a separate data volume, downloading macOS Sequoia, installing to the external drive, and using Migration Assistant to preserve apps and data. Internal macOS remains intact, allowing flexible startup disk switching.
