Electronics: For prototype, arduino and probably a small op-amp circuit modeled on the circuit inside the watch. To make it wearable, we'll probably have to use an attiny or other similarly super small device. | Electronics: For prototype, arduino and probably a small op-amp circuit modeled on the circuit inside the watch.

I already have a set of chokers with surface mount LEDs inside (I've shown this at prior meetings during show and tell). I am unsure of how the LEDs are wired - it's possible that they are all controlled from the same wire, in which case the device will not be able to display as above, and instead will simply flash. I got the chokers from [http://store.rebeccas.com/store/merchant.mvc?Screen=PROD&Product_Code=LI1069&Category_Code= Rebeccas] for only $2.15 each, so if they are suitable they make great kit components. | I already have a set of chokers with surface mount LEDs inside (I've shown this at prior meetings during show and tell).

I've done some google searches, but I haven't been able to find anything like this. There are some pulse-sensing watches, for instance [http://www.chinavasion.com/product_info.php/pName/exercise-watch-pulse-calorie-reader/ Chinavasion: Exercise Watch - pulse + calorie reader] or see some reviews at [http://www.consumersearch.com/heart-rate-monitors Heart Rate Monitors]. These devices almost universally have a small display, but I think a haptic solution could be greatly superior. | I've done some google searches, but I haven't been able to find anything like this.
