Ordered: A pulse-oximeter

It was $13. Be interesting to mess around with it and maybe hack it a bit.

The tech behind it is cool. It’s essentially a light source that can detect the pulse and oxygen content of the blood in your finger.

I’ve had one attached to me twice in my life – once when I came down with strep throat, once when I had my wisdom teeth out.

I just think it’s fascinating that the technology is now available for $13 U.S. Amazing.

  1. The Apple Watch uses similar tech to determine your pulse, I believe. The sensors are built into the back of the watch. They say it may not work well if you have a tattoo there.
