As the long weekend rolls along, I’ve been madly trying to complete my project. Holly is working on the sound files, and I have been busy programming and sewing. We have established the heart rate ranges we would like to work with, and Holly is busy editing the “sounds” that go with each of those ranges.

The next step was to create a logic-flow chart, which would form the foundation for writing our program. I had some help here, along with the programming, from the lovely Bryan (thank you Bryan!). Once the logic was written, the rest was easy for Bryan, and started to make some sense for me.

The ’sketch’ for now works as follows:

- we can now give the sketch a random heart rate, and it will calculate which track the MP3 player should play, and successfully move to that track. Believe me, it sounds much easier than it actually is! The last step now is to successfully get the heart rate monitor interface (HRMI) to talk to the arduino, which is what we are having problems with now.

I’m quite well versed in sewing, so this project has been fairly straightforward in terms of creating the wearable portion. The trickiest part is always creating the pattern. Holly and I want to create a high-collared garment, so that the speaker can be embedded within the collar next to the wearer’s ear. The collar is going to be higher on the speaker side, and then scrunch down on the other side, so the wearer can hear the environmental sounds as well. The photos I’ve posted show the beginnings of patterning, with a paper and mannequin mock-up, and then me wearing the very crude garment that I’ve thrown together, before the tailoring and adjustments I’ve made now.
