Tell us about yourself!

  • This is a great project. My mind was elsewhere with the tech/software...Sleep ApneaYou could put the ECG on your chest as expected to monitor your breathing rate and do the pulse oxy still. With this and decent software you have yourself a machine which can detect sleep apnea and or other sleeping disorders. Anxiety...Another thing this could be used for... helping those with anxiety disorders break habits that start them down the rabbit hole. Apply the ECG to chest to monitor ones breathing rate. People who stress/anxiety a lot tend to shallow breath and or hold their breath (or breath fast). It causes light headiness which then causes more anxiety (vicious cycle). You could pattern ones breathing rates at "rest" and then alert them via vibration or something to let them…

You could pattern ones breathing rates at "rest" and then alert them via vibration or something to let them know when they are starting to get stressed by detecting changes in their breathing patterns (i.e. holding their breath or rapid breathing). With this feedback it could be used as another form of cognitive behavior therapy. Granted this isn't an overnight fix, it'd be a good tool to let people know when they are heading down the path as most don't realize it until it's too late (dizzy).Anyway, thank you for sharing this. Pretty cool.

  • Cool!IMO the only hang up to all of this is the 100Mbit ethernet on the RPi. Since this is the "I/O bus" between all of the nodes I would choose a different board. I would use a BananaPi instead which has 1Gbit ether.If you don't have high I/O load it shouldn't matter which you use :)
