In this episode of element14 Presents, Milos builds an open-source cardiography signal measuring device using a Raspberry Pi Pico W. The project explores how blood pressure monitors work—both manual and automatic—while integrating ECG, PPG, and a DIY electronic stethoscope. From hardware design and PCB layout to firmware development and Python-based data analysis, the video covers the full process. All code, schematics, and data are available via the element14 Community and GitHub for educational, non-medical use: bit.ly/4eYt3z9
