Can I measure the heart or pulse with some form of something, for example puck.js and capacitive touch?
Trying for some gimmics
I will google latter for basic information, but if anyone has "the answer" (not 42) then feel free to show interest or input :)
Changes Gordon, this is great :) http://forum.espruino.com/comments/13526821/
Thanks for all the input: I get back with what results from this in a new message

You can measure it very simply by looking at the change in light that passes through your finger. For example this was a quick hack I did a while ago that uses your webcam to measure your pulse. It's not great, but in the right conditions (light behind your finger) it does work!
So just a light on one side, and a light sensor on the other.
However you can buy more professional units which (I believe) have two lights and sensors at different wavelengths. One is a wavelength that is affected by blood, one isn't - and you can then just compare the two sensor readings over time to get a pulse.

Thanks - that looks great! :)
@OwenBrotherwood, This sensor from Adafruit is small, and will work on a fingertip, or clipped to an earlobe:
It uses 4mA at 5v, and will also run at 3v, with just 3 wires – power, ground, and analog output.
The hardware is open source, and detailed here:

Also lots of Max30100 boards on Amazon, prices all over the place.
Don't worry about formatting, just type in the text and we'll take care of making sense of it. We will auto-convert links, and if you put asterisks around words we will make them bold.
