In Becky’s video about the Adafruit Menta, she challenged customers to send in their applications of the Menta.

Not wanting to let her down, I just completed the design and construction of an ECG simulator (creates that famous heart waveform signal you see on all the medical shows).

As an ardent supporter of Open Source, I documented the design with an 87 page tutorial on GitHub, including all the drawings and software created for the project.

If you take the time to download the tutorial (pdf), you’ll see that it’s a very nice example of applying the Adafruit Menta.
