中文摘要 AI 辅助

我们提出DIY电子手碟（DIY e-HandPan），这是一款专为音乐表演、教育和研究设计的开源、低成本且可定制的手碟音频与MIDI协议界面。该硬件由廉价电子元件和回收材料制成，采用广泛可用的制造技术，使其对创客、教育工作者和研究人员具有可及性。该乐器可在两种不同的微控制器单元（MCU）上实现：Arduino或ESP32。微控制器采集敲击速度，以提供可与原声手碟相媲美的富有表现力的音乐表演。除了实时音频和MIDI生成外，DIY电子手碟还集成了双色LED引导系统，能够显示来自MIDI文件的音乐序列，为初学者和教育活动提供有效的学习辅助。其模块化架构允许用户根据特定应用轻松定制音符数量、硬件配置和嵌入式软件。我们提供完整的硬件设计、固件和组装说明，并讨论设计选择和局限性，以在代表性的教育和音乐表演场景中评估该系统。所有设计文件、源代码和文档均根据开源许可发布，以提高可复现性并鼓励开源硬件社区的进一步开发。

英文摘要

We present DIY e-HandPan, a new open-source, low-cost and customizable handpan audio and MIDI protocol interface designed for musical performance, education and research. The proposed hardware is built from inexpensive electronic components and recycled materials using widely available fabrication techniques, making it accessible to makers, educators and researchers. The instrument can be implemented on two distinct MicroController Unit (MCU): Arduino or ESP32. The microcontroller captures strike velocity to provide expressive musical performance comparable to that of an acoustic handpan. In addition to real-time audio and MIDI generation, DIY e-HandPan integrates a bi-color LED guidance system capable of displaying musical sequences from MIDI files, providing an effective learning aid for beginners and educational activities. The modular architecture allows users to easily customize the number of notes, hardware configuration and embedded software according to specific applications. We present the complete hardware design, firmware and assembly instructions and we discuss the design choices and limitations, to evaluate the system in representative educational and musical performance scenarios. All design files, source code and documentation are released under an open-source license to improve the reproducibility and encourage further developments by the open hardware community.
