Vibration analysis

openTx has introduced a range of new features, ideas and bling. It is fast becoming the firmware of choice for many users. openTx will run on ALL current hardware platforms, including the gruvin9x and sky9x boards. Work has already started to support the new FrSky X9D radio!

Vibration analysis

Aynthing available that would allow you to see vibration levels on your aircraft?

openXsensor is an opensource project (available on github) that let you connect different kind on sensors to an arduino pro mini.
One of the allowed sensor is the GY-86 module that contains accelerometers (MPU6050).
Some calculations (to be defined) on the raw values from accelerometers should probably give vibration levels.

You could also use the GY-521 if you don't need the pressure sensor. It is cheaper and smaller..

GY-521 module has no level converter for I2C bus.
I expect this could be an issue for MPU6050 if Arduino is running at 5 Volt and that other I2C sensors with pull up resitors to 5 volt are use.

Another point of attention is that I am not sure that current oXs code can run with an IMU6050 without having a baro sensor connected too.
This last point can for sure be solved with some minor changes in the code.

The original poster didn't mention any other I2c devices connected at the same time. Even if it was, I have a vario running this sensor and a pressure sensor with voltage dividers on the data lines.. All working good..
I am currently connecting a GY- 521 sensor to an arduino at 5V for another project. So far so good :)

It would be nice if it could run on its own, as it is cheaper and easier to get than the other :)
