Leggo questo interessante intervento di Thomas su HF (
HeliFreak - View Single Post - Msh brain manual Citazione:
No, there will never be vibe analysis tool in this unit.
I'm using (along with other filters) filtering built-in the sensor, so I can't even see the unfiltered data which is needed for vibration analysis.
Having vibe analysis would mean re-create the built in filtering in my software and you know what ? They know their sensors a lot better than me and probably have quiet a few times more man-power than me (and a lot more experienced engineers) to get this filtering working as good as it is. So definitely no vibration analysis.
But for vibration analysis you "just" need acceleometers and some kind of processing/storing mecanism ... accels are quiet cheap, and a small MCU with SDIO capability can be quiet cheap too ... a standalone product could be nice, if I had a real idea of the market I could start working on one ...

Interessante per due motivi:
1) Risponde ad una domanda di qualche giorno fa: niente accelerometri.
2) Il filtraggio delle vibrazioni viene fatto in hw dai giroscopi.
Mo gli chiedo un po di cosette...
