After about 2 months of building the altimeter has been finally finished!
The last missing 7segment displays for the barometric settings have arrived and I was able to finish everything.
All connectors of the connectorplate got soldered and can now be connected to the Arduino, I cut the USB cable and soldered a G12 male/female connector to the 2 parts.
At last the final pictures 🙂
The next projects are already in the making – CabinPressure and VVI gauge 🙂
