Janis Putrams replied to Forrest Frantz's discussion Max mag field length--Why A Max?
"The way I see it is that mag sensor is needed for drone to know the absolute direction at any time in flight. The problem is that mag sensor is susceptible to outside interference and therefore is not reliable.
A low drift gyroscope could be used…"

Janis Putrams replied to Nathaniel Caner's discussion Looking for a good Android App to measuring Vibrations during motor Balancing
"I also failed to find a good Android app so I installed Python for Android and wrote a small script that does it.
Though I did not have much success with balancing as I suspect the sensor is not that good for my phone.
Let me know if you use it and…"
