Reusing Gyroscope - salvaged from old camera

Hi Enes,

With any part, you need to examine the datasheet, it will describe what you're requesting.

You need to find the datasheet for the part (e.g. via google. Or if you somehow have the circuit diagram for your camera with the part labelled).

Unless you find the datasheet, I don't think you can do much except probe it with the power applied to the camera and see what you see. That's 'reverse engineering. That would ideally require an oscilloscope, or a logic analyzer (logic analyzers are inexpensive but there is a learning curve), and not a multimeter.

For a simpler way, Adafruit (and others) sell accelerometers on easy-to-use 'breakout' boards, for $5 USD. There are tutorials for them online (usually they require a microcontroller and some programming, for instance see 'Arduino') since they have a serial digital output stream. There are some accelerometers which have an output voltage and require no microcontroller or programming, but they are likely to be rare, and more expensive these days. Analog Devices is a manufacturer that had analog output versions.

Welcome to the E14 community. Your inquisitiveness will stand you in good here. It may also be a curse when the answers you seek are not forth coming.

I would tend to agree with shabaz and see a more efficient road to the knowledge you seek by using a single board computer or microcontroller. You need to know what you don't know. Using a pre-existing configuration gives you that opportunity. You know it will work and you will know how it should behave. Now you just have to get it to do it.

My first foray into this stuff was using some parrallax sensors. I got to explore the math involved using the components. I stopped short of taking a quadcopter installation and maintenance course. How those type of sensor are used to control a quadcopter is fascinating. Vacation with the family or a week in technical school? Yeah, I need to go on vacation with the family.

Keep the camera components you can always go back and explore them later.

Thanks a lot for the replies. Unfortunately, I can't find any datasheet nor a useful info from cameras specifications. Only it has image stabilisation, perhaps that's why there is a gyro in it. Powering the device and then inspecting what's going on would be a good option but it is no longer able to operate .

I could buy an accelerometer kit but I am more interested in reusing these tiny components. After searching about how accelerometer work and finding out the MEMS, I was under the impression that it should just give arbitrary capacitance depending on the angle.

So then, I can somehow map the output capacitance to the angle, but don't know how to measure capacitance from this components

Maybe I can go ahead and buy a kit and then observe it, as you guys suggested.

MEMS accelerometers almost always have signal processing on board because processing the signals from the tiny capcitance of the sensors is much too difficult and expensive off chip.

Have a look at ST and Analogue Devices websistes to get an idea of what real life accelerometers look like.

I don't recognize the manufactuer ID on the parts in your picture.

How many pins do they have, and when was the phone made.

MK

They are Murata, I think. Based on the M in Circle logo ...

This family? ENC-03RC-R

How many pins do they have, and when was the phone made.

No idea honestly, camera should not be that old, and there are 4 pins for each, I am guessing.

the  PDF on the post looks promising!

This one has difference between the C and D model: https://www.elecrow.com/download/ENC-03.pdf
