WCH’s CH224K datasheet revision (V1F to V2.1) removed single-resistor voltage configuration, disallowing floating CFG pins for 20V requests. This silently breaks existing designs relying on that method. WCH now recommends CH224A, which supports single-resistor mode but requires a 120kΩ resistor for 20V, complicating direct replacement without extra pads. The article questions whether such functional changes warrant a new model number.

The author recounts a post-typhoon weekend road trip to Nan'ao Island with college roommates. Clear skies after rain created ideal photography conditions, and sparse crowds kept traffic light on the usually congested two-lane bridge. Highlights include the Tropic of Cancer landmark, Haiquan Bay, and the scenic coastal ring road. However, driving in Shantou demanded extreme caution due to unpredictable e-bikes. All photos were taken using a DJI Pocket 3 and a Huawei Mate70 Pro+.

The GL-RM1PE is a PoE-enabled IP-KVM device providing remote BIOS-level control, 4K@30 video, low latency, two-way audio, file transfer, and ISO mounting for OS installation.

This article provides a systematic guide to magnetic core selection for power electronics, covering key parameters (permeability, saturation, core loss, Curie temperature), comparing materials like ferrite, sendust, permalloy, amorphous and nanocrystalline alloys, and reviewing core structures (EE, PQ, toroidal). It offers engineering recommendations for AC/DC, DC/DC, PFC, and inverter applications, emphasizing frequency matching, loss control, and cost balance. Engineers gain practical reference for choosing cores.

The article reviews GEIL Millennium DDR5 5600MHz 64GB laptop memory, a SO-DIMM kit with CL46 timing and 1.1V voltage. It uses CXMT DRAM chips from 2025. AIDA64 benchmarks show read speed 79GB/s, write 81GB/s, and latency 112.7ns. Purchased for 1158 RMB, it serves as a straightforward laptop RAM upgrade option.

Review of MECHREVO Code10 AI laptop (Ultra7-255H, 32GB) covering unboxing, benchmarks, and teardown. It delivers solid performance: CPU-Z single 833.9/multi 10223.9, Cinebench R23 21378, SSD read 4598 MB/s. The 15.3-inch 120Hz display has good color accuracy after calibration; keyboard and speakers are improved, but the laptop is heavier and the camera is poor. Includes 99.9Wh battery, dual M.2 slots, 140W GaN charger, and Thunderbolt 4. Preinstalled CodeGeeX AI assistant could not run due to memory allocation. Value reduced by absence of Guangdong subsidy.

This article benchmarks a custom 88,000 RMB bare-metal server built by Haoliang Cloud Engine, powered by Intel Xeon 6980P with 128 cores, 256 threads, and 256GB DDR5. CPU-Z multi-core scored 84,800, Cinebench R23 multi-core 86,395, memory read reached 281GB/s, and RAID1 SSD sequential read hit 3,852MB/s. Designed for AI, HPC, and data-intensive workloads, it demonstrates extreme core density and memory bandwidth.

The article details a teardown of the ZGRL-80 fill light, revealing false advertising: it lacks PD fast charging despite claims, drawing under 10W via Type-C, and its 80W rating is exaggerated with LEDs consuming about 40W. The analysis covers internal circuitry, battery configuration, and thermal imaging, helping readers identify misleading specs and understand budget device limitations.

An upgrade to AMD Ryzen 9 9950X and MSI B850M MORTAR WIFI was tested, replacing an Ultra7-265K system that had random crashes. The board features WiFi 7 (FastConnect 7800), two PCIe 5.0 x4 M.2 slots, USB 20Gbps Type-C, and 5Gbps Ethernet. Benchmarks show the 9950X outperforming the 265K by about 20% in Cinebench R23/R15 and Ludashi, while CPU-Z and Geekbench results are close. Integrated graphics are considerably weaker. Power draw ranges from 135W idle to 511W under dual load. The 265K offers better price-to-performance for productivity; the 9950X runs hotter and is harder to cool.

An e-bike owner installed a Coulomb counter on a Yadea M16-H with a 48V 23Ah lead-acid battery. The device uses current integration to display accurate remaining battery percentage, voltage, power, and estimated range, avoiding voltage-based gauge inaccuracies. It also shows regenerative braking charge (about 275W) and supports battery health management. Installation involves wiring the sensor in series with the negative terminal and setting battery parameters.

This article explains how to deploy a Better MC [FORGE] BMC4 modpack server on Linux using MCSManager. It includes client and server downloads with a Chinese language patch. The modpack adds over 270 mods, 100+ quests, adventure and RPG exploration, and multiplayer support. The guide covers installing MCSM10, Docker, and Java 17, uploading the server ZIP, running it via run.sh, and editing server.properties. At least 4 cores and 8GB RAM with strong single-thread CPU performance are required. Players join using the server IP and port, while admins can grant operator permissions via console commands.
