The EC(stin)G(y) provides an end-to-end design and implementation of a cost-effective, compact electrocardiogram. It connects to a computer via USB, monitoring a patient's cardiac signal and heart rate over time.
This project can serve as a template for any device measuring the heart's electrical activity and can be easily adapted to the user's needs. By open-sourcing the design files and code, the project aims to make medical hardware and technology more accessible and reduce the barrier to entry for prototyping.
Each folder corresponds to a specific stage of development or a component of the final product.
