A Python platform that streams vibration data from a PW-RVT (Modbus RTU) sensor and renders live multi-channel charts in the browser — with automatic CSV archiving and optional SQL upload, all driven from a web UI. Built on a five-thread, queue-based architecture with 50:1 downsampling. 以 Python 打造的振動資料採集平台，透過 Modbus RTU 從 PW-RVT 感測器讀取資料，於瀏覽器即時繪製多通道連續曲線，並自動分檔儲存 CSV、選用上傳 SQL，全程透過網頁介面操作。採五執行緒、佇列式架構並以 50:1 降頻優化效能。

Real-time vibration acquisition from an ICP DAS PET-7H24M over TCP/IP, optimized for ARM64 Linux. Features dynamic channel toggling, live Chart.js plotting, and high-throughput buffered CSV writing. 針對 ARM64 Linux 優化的振動資料採集系統，透過 TCP/IP 從泓格 PET-7H24M 讀取資料，支援動態通道開關、Chart.js 即時繪圖與高效能緩衝式 CSV 寫入。

A high-performance C++ data-acquisition library for National Instruments hardware, offering a simplified multi-channel API, multithreaded real-time processing, and INI-configured CSV output across Windows and Linux. 為 NI（National Instruments）硬體打造的高效能 C++ 數據採集函式庫，提供簡化的多通道 API、多執行緒即時處理，以及由 INI 設定檔驅動的 CSV 輸出，並跨 Windows 與 Linux。

A C++ tool that synchronously captures from NI-DAQ and multiple ALSA audio devices at once, organizing recordings into timestamped, labeled CSV files with configurable save intervals. C++ 開發的多來源同步採集工具，可同時從 NI-DAQ 與多組 ALSA 音訊裝置擷取資料，並依時間戳與標籤組織為 CSV 檔案，儲存間隔可自訂。

A production-grade AWS Greengrass v2 edge component for industrial data acquisition with National Instruments hardware — real-time streaming to the cloud, backed by CI/CD lint/validate/test and release pipelines. 正式環境等級的 AWS Greengrass v2 邊緣元件，搭配 National Instruments 硬體進行工業資料採集，支援即時串流上雲，並具備 CI/CD 檢查、驗證、測試與發佈流程。

An IoT home-monitoring system built with a Flask backend and a Vue frontend for collecting and visualizing environmental sensor data. 以 Flask 後端搭配 Vue 前端打造的 IoT 居家環境監控系統，用於蒐集並可視化環境感測資料。

Infrastructure-as-Code that provisions a self-hosted Nextcloud on AWS: an EC2 web tier, S3 object storage, IAM roles, and a user-data bootstrap — fully reproducible through Terraform. 以 Terraform 自動化部署自架 Nextcloud 於 AWS：EC2 網頁層、S3 物件儲存、IAM 角色與開機 user-data 腳本，是完全可重現的基礎設施即程式碼。
