Arduino speaking variometer

These are my backup project notes - please email me if interested

Build a helmet mounted variometer for paragliding that speaks
the altitude above take-off in feet and the minutes since the flight began
Then add a clock and SD card in order to store flight data

Part 1 - Driving the speaking chip WTv020sd16 from an Arduino Nano

Part 2 - Getting the Tiny RTC clock to run

Part 3 - Hacking an SD card adapter to mount a micro SD card

Part 4 - Bring it all together - to come!
