DESCRIPTION: This pedometer is $1 plus tax brand new at Dollar Tree. Modding this to a potential coil counter for a winding setup is as simple as it gets. Googling shows me that I'm not the first person to have this idea... this guy got it to work at slower speeds ("220rpm max") with his fishing-reel winder. http://www.reranch.com/reranch/viewtopic.php?t=38808
