diyECG-1opAmp

A surprisingly good ECG is possible from a single op-amp. This project contains circuit and software.

Setup

This software needs certain libraries like PyQt4 and numpy, so the easiest way to make sure you have versions of everything that get along is to download a pre-packaged Python distribution. This software has been tested and works with WinPython 3.5.2.1 (not the Qt5 one)

  • install WinPython-64bit-3.5.2.1 (not the Qt5 one)
  • download this project and modify go.bat to reflect where your python.exe is
  • build the circuit, plug it into your microphone hole, and run go.bat
