I have several ultrasonic measuring systems I would like to sell.  They
measure from 2 to 30 feet, tenths of feet resolution.  They would be a
great source for parts for an ultrasonic project, or can be used, as is,
for ultrasonic measuring.  I have several that come with the housings but
most are just the electronic guts.  The following will be include:

                1.)  Poloroid ultrasonic sensor and data
                2.)  ultrasonic driver circuit
                3.)  2 lithium batteries
                4.)  piezo buzzer
                5.)  LCD display
                6.)  schematics and circuit explanation

        price:
            without housing   $15 plus $3 shipping
            with housing      $18 plus $3 shipping


Will sell first come first served determined by email date.
