Mounted a pendulum that measures acceleration on top of some wheels for a school project. I want to put some accelerometer puns on it. Anyone have any ideas?
Much appreciated!
Now mobile phones have a cursor, but you have to tilt your phone to use it.
Bonus: Your cursor has inertia.
The accelerometer as used by Uber is the number one reason I ditched my iphone and won't buy an android. I really don't like the data that gets gathered by an accelerometer and would like to be able to turn it off, or alternately to pull it out.
Is that an option? Can I physically disable the hardware and still have a functional phone? I don't need it to be a GPS, I have a separate GPS.
ETA: Here's the reason to get rid of your accelerometer. I never in a million years would have agreed to ever touch something that could track me like this knowingly. It made me want to throw up that I'm tracked this much. People on the sex offender registry have more privacy than I do.

Exerpt from the above. Just an example of what can be known about you from just walking around with an accelerometer in your hand or in your pocket or in your purse or jacket pocket or backpack, and I bet money they can eventually figure out who is holding that phone.
2.6 Inference of Demographics Estimates of demographic variables such as age and gender can be made based on data from body-worn accelerometers. It has long been demonstrated that adults and children differ in their smoothness of walking, which is reflected in accelerometer readings [67]. Menz, Lord and Fitzpatrick compared gait features between young and elder subjects using acceleration signals and discovered that younger subjects showed greater step length, higher velocity and smaller step timing variability [68]. Using data from accelerometers in smartphones, Davarci et al. were able to predict the age interval of test subjects with a success rate of 92.5% [69]. Their work is based on the observation that children and adults differ in the way they hold and touch smartphones. Experimental results by Cho, Park and Kwon indicate that there are also gender-specific movement patterns [70]. In accordance, research has shown that it is possible to estimate the sex of individuals based on hip movements [56], gait features [71] and physical activity patterns [72], all derived from accelerometer data. An experiment also revealed that female gait patterns are significantly influenced by the heel height of their shoes [73]. Weiss and Lockhart emphasize that accelerometer-based gender recognition can work independently of a subjectβs weight and height [56]. Even acoustic vibrations caused by a personβs

Are there any reasons why this wouldn't work?
I want to nuke the accelerometer in the phone, I think forever, I really don't want anything the accelerometer has to offer me. Can I take the phone to an electronics shop and have its balls clipped permanently?
I am working on a project where I will be illuminating LEDs based on deceleration rate. For each .1g of deceleration another led will turn on. I think I've got that part down.
The deceleration rate will not be uniform, and I want the lights for the maximum deceleration rate to remain on for a few seconds after the deceleration ends.
I'm having a hard time figuring out how to keep a light on after the deceleration has decreased, but also keep looking for a new maximum.
For example, if my deceleration looked like 0 .1 .1 .3 .5 .4 .7 .3 .1 0
I would want the 7th led to stay on for 3(ish) seconds, I don't want it to get stuck on .5 and not pick up the following .7.
I'm not looking for someone to write the whole code for me, just help me figure out the logic.
Thanks
So the December update seems to have ruined my accelerometer. Auto rotate no longer works. I've used a sensor test app on my phone and my wife's 4a... Hers work, mine do not, so it appears I have an issue. Could this be fixable with a reset or is it definitely hardware? Never dropped the phone and even if I had, it's in a massive Spigen case π₯
There is a new rom hack of Kirby Tilt nβ Tumble that removes the need for the accelerometer. Kirby is controlled with the d-pad for movement with the patch. I own the original game but itβs still nice to see this after so many years. The patch also changes the mapper for better compatibility.
It allows the game to be played on flashcarts and emulators. Great work by the author of the patch (infinest)!
How to Accelerometer use to on the desk play music.
It takes up to 5-6 seconds to rotate, so all my quick shots end up being the wrong orientation. I also have face detection enabled. I wish there were an actual button to press to flip the orientation.
Just got a new Google Pixel 6.
Accelerometer is completely inoperative.
No auto-rotate for any apps or my camera β all photographs are taken vertically regardless of how I orient the phone, forcing me to manually rotate all of them in editing. I cannot look at photos in landscape, and I cannot watch videos or movies in landscape.
I used the Sensor Test app, and the accelerometer is not working at all β the little football just stays at the bottom of the screen no matter how I tilt the phone.
Tips?
I am trying to learn about this stuff so that I can instrument a vehicle which will be tested on a track. Any kind of source is appreciated.
I know I'm supposed to use the I2C, but I can't find how I'm supposed to read from 2 registers at the same time since I need to read X_L and X_H at the same time to get the x-axis for example.
I know what an FFT is and does. My question is once data is obtained from an accelerometer and thrown into an FFT, and we get the resulting magnitude spectrum, what do the magnitudes actually signify in the context of things in the real world. Say we have a peak at 100Hz. What does that mean in the world of vibration? Or maybe it's really simple. I don't know.

Hi everyone, first-time post here. This is my schematic for ATTINY1634 with an accelerometer KXTJ3-1057.
I would like to have a review before moving to the layout. My biggest concern is the ISP debug connection as my plan is to use an ATMEL-ICE to flash the program thus I would like to get this verified. In addition, will these connections affect my I2C bus connecting to the accelerometer when I flash the firmware? Finally, if you spot any other mistakes, please let me know in the comment!

I am designing an apparatus for my workplace that slowly tilts in order to measure roll off angle of water drops. I am going to use a DC motor to drive it, so it should move smoothly without any jitter like a stepper motor might have, and I need to measure the angle accurately somehow. Ideally I want to know the degree of tilt down to an accuracy of Β±0.1Β° but up to Β±0.5Β° should work. What would work best for this purpose? Thank you!
I bought a used PS Vita a few years ago and the gyroscope/accelerometer has never worked. Does anyone know if this can be fixed or replaced or am I out of luck? I've searched online and I can't seem to find anyone else who has this issue. It makes games such as Uncharted: Golden Abyss unplayable with it's mandatory motion control sections.
