Biometrics for heart rate, galvanic skin response & body temperature

Hello everyone.

I am interested in DIY-ing a biotracker for the following

  • galvanic skin response
  • heart rate
  • body temperature

A quick search through the forums showed no recent discussions on these. (They go back to 2010 and 2011).

So is anyone fiddling with something similar? I am looking for suggestions/recommendations before I go ahead and buy parts to avoid mistakes. (newbie talks!)

I've found BITalino as another option. I don't understand the difference.

How would you recommend I start this project?

Thanks.
