Teardown of a Piezoelectric Vibrating Gyroscope
Рет қаралды 11,637
Күн бұрынIn this video I did a teardown of an old analog piezoelectric vibrating gyroscope that was found inside a Cannon ZR-65 miniDV camcorder. www.kerrywong.com/2019/02/03/t...

wow Kerry, check that out so cool.. I have never seen a piezo active gyro like that.. thanks

Never could figure out why they insist on calling these devices gyros... nothing spinning in there! Just the opinion of an old gyro compass technician. This device senses inertia... a gyro use centrifugal force and precession. Note: a gyro compass also uses inertial sensors WITH its gyros.

Does your caliper have a depth measuring probe/blade on the opposite end?
@KerryWongBlog 5 жыл бұрын
Yes it does, but there was a gap between the chip and the PCB so it wouldn't be very precise anyway...

Try lighting it up with a high power LED pulsing at a slightly higher or lower frequency, then record a video of the device in operation.

Not sure if light would have any effect on this?

@@KerryWongBlog The point is to get aliasing so that the movement would actually show up on video. Otherwise, it would take an absurdly fast camera to capture the vibration.

Would be interesting to connect the gyro pins to a multi channel scope, or differential opamp connected to one channel. That would show the phase differences, when it's being rotated.

Yeah I was thinking about it when shooting the video, but given the size it was difficult enough to just hold one probe in place....

@@KerryWongBlog You solder wires to things that are tricky to get probes onto, or just hard to get at. Then connect to those wires.

note : there is a depth gauge on the other side of your caliper.

Very interesting video, thanks. FYI, use the other end of your calipers to measure depth.

Yeah I thought about using the other end, but there was a gap between the PCB and the bottom of the chip :-) thought I would be able to eyeball it...

It is a gyroscope.

But what did you show? Almost nothing how it works. What is dependency of tilt/pan or x/y/z movement? Poor video at this time.

Well, if there's enough interests I can certainly do another video, the purpose of this one was just to show what's inside.
