Hi Darrel ,
hi Acetronics (It's me bitmaniac from rcgroups -navlights)

I am in the progress of developing my own ALT timer for F5J category
I want to deactivate/arm a mechanism at 300m for example.

I am using MPX4115A a max187 (12bit) and a pic to read altitute.

thought #1: I wonder if I can use an eeprom to store look up table of all alt values you can meat here in Greece (0m to 3000m max) and not use extensive calculation to determine alt.

thought #2: Also I am thinking of just usin ground kPa - specific height kpa and the difference (in kPa) gives me the heigth I want to calculate.

Are my thoughts correct or I miss something?!!

Thank you for your time my friends!
