FreeIMU GUI now making nice 3D Spheres

Submitted by fabio on Mon, 2012-12-17 17:35.

I'm happy to finally publish the code for drawing nice 3D scatter plots of the incoming accelerometer and magnetometer data for the Ellipsoid into Sphere calibration available in the FreeIMU GUI. This will be soon released in upcoming v0.3 of the FreeIMU GUI but for now is available only on the repository.

This will allow users to have a direct realtime feedback on the performed motions and how good/wrong their sensors are calibrated.

Below a couple of screenshots. Note how screwed up was this magnetometer on it's Z axis, compared to the calibrated sphere output.

FreeIMU to measure sea wave

Submitted by Francisco Arenas (not verified) on Thu, 2014-09-04 21:42.

I am working on a personal project relative to the development of a buoy to monitor the sea wave. To do this I am thinking to calculate the displacement of the buoy with IMU sensors. I am working with FreeIMU and the sensor GY-9150 and GY-86. I would like to know if anybody has worked with very small accelerations or slow displacements. I am studying Kalman filter, maybe with a precise model I can get good measure.

Finally I would like to thanks and to honour the memory of Fabio and his work.

How to get fv_kicad.lib

I've been trying to download a copy of the fv_kicad.lib from the GUI Repository.
I must be unusually thick because I can't seem to figure out how to do this.
Can someone explain to me how to go about doing this.

I have encountered about 3

I have encountered about 3 modules with "problems." In every case, removing one "&" fixed the problem, which is actually the proper way to be coded, not really an error. Opening an issue on DO takes maybe one minute. I'd rather have the modules fixed.automatic pet feeder

Ho saputo oggi che Fabio non e ' più fra noi.

Ricordiamolo come un brillante ragazzo pieno di voglia di vivere e sperimentare.
