This biggest challenges for the project are :
1) How do I keep the size small and at the same time keep it functional as a regular pedometer ? ( The last thing I want is a huge box hanging off my belt loop
2) How do I power/recharge the dang thing ?
I want to use small batteries but at the same time have enough charge for a 5 mile walk
at 3 to 5 mi/hr
3) How do I upload data from the device . Do I want wired data or wireless ?
4) How do keep it inexpensive to build ( if it is going to cost more than the a FitBit,
what's is the point, right ?? ). I want to use stuff I can find around the house.
