Oximetrics

Nov 2, 10:24 PM

So I decided to combine my geeky interests for a couple of hours tonight— I built a simple oximeter while watching election results. While the democrats really sucked at keeping the house, the good news is that the blood-oxygen sensor works. I can drop the reported numbers by holding my breath. It’s not calibrated to anything in particular.

If you want the sketches or schematics, drop me a line.
