1 Guitar Strings
Different strings break at different rates. You can buy them singly or in sets of 6 (occasionally with a spare top E) - really what you want is just in time delivery of a new set wtih a distribution of strings (EBGDAE) that matches the wear/tear rate for you, your guitar (classical, flamenco, acoustic, electric etc) and tone/newnewss you like - this could be crowdsources by instrumenting tuning apps on phones which would notice when you tune from way below (e.g more than a 5th below the right note for that string, probably indicates a new string being put on) -
The statistics could be aggregated, and classes of users found, and then companies (like my fave ) could build orders for you -
2 Bicycle Wheel Spokes
I've lost 4 spokes over the last 5 months cycling in Cambridge - probably, they went on the appalling potholes on station road, or the tree roots across burrel's walk - wouldn't it be nice to know where these occcurred so I could report them to the council (and get money:-)
This could easily be done with accelerometers in smart phones....and GPS - look for rapid up/down movement - then afterwards (when a spoke has gone) you should be able to find the periodic wave of the bike as the wheel is now eliptical....
