I don't know how can I thank you so much. I am a Civil engineer and PhD student . My thesis is about Operational Modal Analysis. We will use accelometers on the Dams. with finite Element Method . So I learned many subjects from this video. Thank you again.

[MrLijoisthebest]

you guys are amazing. what a sequential explanation. I understood everything. and you simplified such a complex thing. that was bind blowing! Cheers!

[exmo]

What a great, simple, yet informative tutorial! Practical Ninjas indeed! Thank you!

[desireejaques]

The clearest explanation on accelerometers that I have found

[sankethowal]

Great explaination mate in short time.

[JohnFHendry]

Great video... not many people can explain something connected to F=ma and take it to F=ma=fs=kx and keep it simple. Shows why one crash hitting something hard like a cement wall just right can damage the accelerometer and the value of soft mounting the flight controller as well as the disadvantage exposing why custom made application specific mems have an advantage (think DJI) to create a vibration frequency tuned flight controller board... and why a FCB is thrown off mounting it on another reference frame of vibration. In time Flight controller boards will be self tuning on the electro-mechanical level and BETA Flight will only assist with PID moment arm time frame motion rather than interrelated frequency tuning. It's getting better all the time....;-)

I can't believe how good this explanation is.

[macronencer]

This is great! I'm going to watch the other videos too. What I'm trying to find out is how the system can differentiate between gravity and acceleration, given that they are equivalent. Perhaps this is done by using the other components to correct for it somehow?

[AV-kldx]

Great work bro. Helped me a lot. Thank you so much for this video.

[dcpowered]

There is a mistake in the video 03:57 when the acceleration is to the right, the movable frame should shift in the opposite direction. It's Newton's first law of motion or the law of inertia, which is the tendency of the movable frame to resist any change in motion.

[robaidulislam]

I have seen few of videos in this topic... Among them it is the best.
Big thanks to u sir

[mirsiadulmurshalin]

This is really good explanation keep it up

[avocado]

Very well explained! One small suggestion is to lower the background sound.

[cwildsblog]

pretty nice explanation on accelerometers! I hope the rest will be online soon! thanks

[rinofaizar]

where's the gyroscope working principle's video?? i really enjoyed your explanation, thank u so much and i'll be waiting for the gyro's video ^^

[amirulazhar]

good explaination with the aid of the diagram. Thank you!

[nsiddiqi]

Brilliant Video. Love the style in which you have presented. Excellent. Very educational and well presented.
