For $29.95 at the local giant hardware store/lumber yard (Hechinger's),
I got a little black box with LCD display that works acceptably for rough
measurements (displays in feet with one digit after the decimal) of
room sizes in a house.  It won't handle over about 50' outdoors, though.
It may not be the learning experience you intended for your project, but
you could buy one and take it apart.
