Depending on how much weight it is you want to measure (can't remember
from the original posting), why not use a force sensing resistor.  I
have a business card from a company that actually includes on the card a
force sensing resistor.  By attaching a ohm meter and pressing on the
card, one can see the resitance vary.  This can then be used to generate
a voltage swing, run thru an A/D and digital counter (see Intersils Data
Book page 7-66 for details).
