  • Yes, this part would work quite well. I suggest shining the light through a finger instead - this is how pulse oximeters work. The best wavelength is between 800nm and 940nm, since you want to look for changes in oxyhemoglobin. See (http://en.wikipedia.org/wiki/File:Hemoglobin_extinction.png)

No public wish lists :(
