digital odometer..anybody can help me??

i want build a digital odometer..can anybody help me..give some idea or idea..thanx :?:

Well... You could just buy such things, at any electronics store. Or if you wanna put yer hand in it, you need first of all something to work as your display. There are small cristal-liquid screens that have pins in order to display a message, or you have those digital boxes, where you have 'n' digital places, you could fill'em up. Then, you need your circuit... What exactly do you need to do with it? Is it just a counter? What's an odometer ... Is it a meter for odor? I mean, smell??
