For an independent hardware commission from Accele AI, I designed and hand-assembled Claude Chime's ESP32 peripheral power board. The roughly 28 × 27 mm PCB combines single-cell charging, two separate boost rails, gated battery-voltage sensing, and a 5 V push-pull solenoid driver. I completed basic power-up and interface checks; the client's firmware engineer later reported normal complete-device operation.受 Accele AI 委托，我独立设计并手工焊接了 Claude Chime 的 ESP32 外围电源板。约 28 × 27 mm 的 PCB 集成单节锂电池充电、两路独立升压、受控电池电压采样和 5 V 推拉式电磁铁驱动。我完成了基础上电与接口测试，客户固件工程师随后反馈整机运行正常。

I built an acrylic-and-foam laptop cooler, with a Windows application sending temperatures over Bluetooth to an ESP32 fan controller. A later STM32 board reached serial control but never rejoined the complete system.我做了一台亚克力与泡棉散热器，用 Windows 程序读取温度，经蓝牙控制 ESP32 和风扇。后来重画的 STM32 板完成了串口控制，尚未重新接成完整的温控整机。
