Scratch built altimeter

[Edward Deerly]

Hello all,
I am wondering if anyone has any idea where I can find info on
building a Barometric altimeter. As light and small as possible because I
want use it for Model Rocketry. I am hoping that some manufacturer has an
inexpensive, one chip solution for this.
TIA,
Ed

Cyclists have been using altimeters in their cycle computers for
years. They are small enough to be worn as a wristwatch. Check out the
cyclist sites. They might not have the response required for rockets,
though.

A Google search on Pressure Transducer will flood you with what you want.
