I have bought a sensor from Honeywell some years ago with the intent
to build an altimeter. Never tried it since since I have -7 diopt
now and I'm probably no longer air worthy as a glider pilot.

If I still can find it, you can have it. Either per mail or across
the table in the Zwickel in Dudweiler, some Friday evening.
