Selected Projects
| Project | Description | Tech Stack |
|---|---|---|
| Claude Usage Widget (2026) | A native macOS desktop widget that displays the 5-hour and weekly quotas of a Claude subscription, a daily usage heatmap, and the token usage and estimated cost of local Claude Code sessions. Card sizes, corner radii and grid snapping reproduce the measured geometry of system widgets; quotas are read through an embedded WebKit view, and log statistics are deduplicated per message. Open source: GitHub | Swift · SwiftUI · WebKit · macOS |
| Multimodal Mecanum-Wheel Robot Control System (2026) | A web-based remote control service built on the RK3588, operable from browsers on phones, tablets and computers; integrates thermal-imaging temperature acquisition, a six-axis IMU and real-time camera streaming; the stop-failure fault in the chassis STM32 firmware was located and fixed | RK3588 · STM32 · Python · HTTP/MJPEG · Thermal Imaging · IMU |
| RK3588 One-Click Deployment Tool (2026) | A one-click deployment script addressing offline devices and tedious manual uploads: it downloads offline dependencies, uploads code and configures start-on-boot automatically, and supports PowerShell and Git Bash. Open source: GitHub | Shell · PowerShell · adb · init.d · Python |
| Multimodal Intelligent Monitoring System for Conveyor Idlers (in Chinese) (in progress) | Multi-sensor fusion (vibration, thermal imaging, vision) combined with edge inference for online fault diagnosis of conveyor idlers; the camera integration and data acquisition modules are complete | RK3588 · OpenCV · Lightweight Neural Networks |
| PINN Solution of Biot Consolidation in Saturated Soil (in Chinese) (2025) | The governing equations are embedded in a neural network as constraints, yielding a mesh-free, differentiable solution of the consolidation problem; an introductory series of notes and code accompanies the work | PyTorch · PINN · Numerical Analysis |
| Interactive Convolution Operator Lab (self-developed tool) | Image convolution performed in the browser: after loading an image, classical convolution kernels are applied, the multiply-accumulate process is expanded point by point, receptive fields are traced, and pooling, upsampling and the U-Net encoder-decoder structure are demonstrated; images are not uploaded to any server | JavaScript · Front-end Interaction |
| Young’s LLM (self-developed tool) | A personal large-language-model chat assistant based on DeepSeek, with streaming output, ready to use directly in the browser | JavaScript · DeepSeek API · Cloudflare Pages Functions |
| Steel Box Girder Construction Design and ANSYS Dynamic Simulation (in Chinese) (2024) | Design of auxiliary supports for a steel box girder and dynamic finite element simulation of the construction process | ANSYS · Finite Element Method |
Further small web pages are collected in Tools.

- Content: For chemo-hydro-mechanical coupled consolidation of a clay buffer layer under time-dependent loading, two intermediate variables are introduced to decouple the governing equations; analytical solutions under ramp and exponential loading are derived and verified against COMSOL Multiphysics numerical results. A parametric analysis identifies the controlling factors of pore pressure dissipation and contaminant migration.

- Content: 26 sets of 1g model tests were designed, combining foundation position, embedment depth and structural load. Three modes of interaction between the foundation and fault rupture are identified and the transitions between them are delimited; a classification method based on observable displacements that accounts for structural load is proposed.
