Make Your Own ECG System at Home

Scott Harden, of The Blogging Rotagonist, has created a cheap, functional DIY ECG machine that you can build at home for $1 worth of parts.

He has circuit diagrams, various plots of his data, and the Python code he used for his project in this detailed blog post, along with videos like the one below.

I wonder how many other amazing self-tracking devices could be built from inexpensive, readily available materials?
