That seems like a lot of work.
OP - Just throw an accelerometer in there and call it a day. Your phone should do nicely ^^(/s)
I got AZ yesterday and ran my phone's magnetometer over the site using this app and found nothing.
BTW, did you notice the woman at 9:35 with a quarter stuck to her arm? I don't have any American money available, but do quarters attract each other? I think that just shows how easily people can fool themselves.
Physics Toolbox Suite makes sensor data collection accessible to anyone who owns a modern Android device. Mobile devices now make sensitive data collection available to nearly anyone who owns a smart phone or tablet. Without any extra expensive or single-use technology or probeware, users can collect and analyze data for recreational, educational, or scientific purposes. The app is free and has no ads.
It seems hasSystemFeature(PackageManager.FEATURE_SENSOR_BAROMETER) is returning false, which means Android is saying the device doesn't have a barometer. Does an app like this show barometer? https://play.google.com/store/apps/details?id=com.chrystianvieyra.physicstoolboxsuite&hl=en_US
This! I only have a Note10, Note9, and Note8 to test. I have whitelisted phones manually because people would get upset when their random-brand-phone didn't work, despite all my attempts to make it clear only Samsung (and some Pixels) work with it. I will add the S20 FE in the next update.
Edit: I don't think the FE has a barometer. Can someone see if it shows in an app like this: https://play.google.com/store/apps/details?id=com.chrystianvieyra.physicstoolboxsuite&hl=en_US
This is the most accurate way to calculate the firerate on an AEG. It only involves your phone, no high-speed camera or anything.
Download the Physics Toolbox Sensor Suite from the Google Store. It will allow you to plot data from various sensors on your phone.
When your gun fires, the current it'll draw varies over time, meaning the magnetic field around the motor will also vary over time.
Simply use the app's "magnetometer" feature to plot the magnetic field value over time as you shoot in full-auto. Don't forget to place the phone next to your motor.
You will then need to measure the time between each "spike" in the graph. It is read on the X axis.
Once you are done, divide 1 by that time and you will get the firerate in BB's per second.
Any sound at or above 85 decibels can damage your hearing. If you have a phone, get an app that measures decibels. I have this app which includes a sound meter that measures decibels. Just hold it up where the volume is and it'll tell you. You could also potentially put it in between your headphones while playing and see if your headphones are too loud.
Take it from me (and probably many others here): protect your hearing at all costs. You'll regret not doing so later. I do. A few years ago I got "musician's earplugs" that are custom molded to my ears and have a filter that cuts the decibels by 15dB. They're pretty pricey ($250 Canadian), but oh, so worth it. I wear them when I go to see a band play too. You can also get different filter "levels". I think the next one up is 21dB... Anyway. Make sure you're not damaging your hearing.
Very cool idea.
I recently discovered the Physics Toolbox Sensor Suite app, which seems to be a more full-featured version of the app you reference for Android. It has a Roller Coaster mode that can simultaneously graph g-force and acceleration (if you choose those two in the settings--other options involve the barometer). The difference being that the "acceleration" graph filters out the "ambient" 1g. I'm not sure if that would add anything meaningful to the data or not.
I was already planning on having some fun with this app on my next Hershey trip. Happy to send you the results.
You could use a phone app that tells you the color of whatever your camera is pointing at such as this one.
On a side note the claims/advice in the product photos are hilariously atrocious.
Peer review is to prevent dolts from posting random garbage like this 'paper'.
Do you know why this 'paper' is complete made up garbage?
Its pretty simple... everyone on earth is carrying around a very sensitive magnetometer in their pocket.
Do you know how your phone identifies which direction you're facing? A magnetometer.
I'm vaccinated, let me check if I'm magnetic. Oh look, the compass app still points north, and doesn't just point at me or my arm.
Wow, such science! So amaze! Do I get a Nobel prize now?
Maybe an appl like this? https://play.google.com/store/apps/details?id=com.chrystianvieyra.physicstoolboxsuite&hl=en_US
Basically turns your phone into a data logger that can poll data from your accelerometers. I haven't used this product but it was the closest to what i was looking for.

Without any extra expensive or single-use technology or probeware, users can collect and analyze data for recreational, educational, or scientific purposes.
I recently found an app that helps to visualize magnetic fields called Physics Toolbox Sensor Suite. It let's you tap into the sensors in your phone, one of which is a magnetometer. If you know the orientation of the magnetic field you're measuring, you can move your phone around the field and watch the x, y, and z magnitudes change (it's graphed over time) to get an intuitive understanding of the field strength in space. There's also a 3D vector tool in the same app which works pretty well.
Here it is in Google Playstore
I'm guessing there's a version for iPhone too
Download an electromagnetic field detector app. They aren't super accurate on a phone since phones emit their own EMF radiation, but you'd pick up a large spike if there is some real interference. Which would definitely be the reason electronics are bugging out. This could be due to a power box maybe below the booth, something with a high electric current. A magnetometer would detect high magnetic levels, that could be an issue, but probably not.
I have an app called Physics Toolbox Sensor Suite that has a bunch of different sciencey tools in it. And an EMF detector is one of them along with a magnetometer.
I'll bet you'd be very surprised what your phone already is already capable of, most of the cool sensors aren't used for anything a consumer usually cares about but. There are apps that make that data available to you though I've used "Physics Toolbox Sensor Suite" for my phones in the past. There's so much data your phone is tracking constantly. Gyroscope, g-force meter, light meter, magnetometer, barometer, multiple temperature sensors, gps of course, your microphone has tons of uses etc. most of those things are made available to the user with that app or other similar to it! It does feel like a real life tricorder especially when you first discover all of the different types of sensors and raw data coming in.
This app:
Gives access to various sensors including accelerometer, barometer, compass / magnetometer. ~~Possibly rather~~ very nerdy.
The Magna-AR - "augmented reality visualization of magnetic field vectors" feature is kind of bizarre. Anti-vaxx lunatics should be using it to scan for traitors at their cult gatherings.
Oh!!! I came back here because playing around with physics sensors on my phone I found that the toolbox does colour detection
https://play.google.com/store/apps/details?id=com.chrystianvieyra.physicstoolboxsuite Under "light" they have colour detections.
Works fine around my room and can zoom in so with a bit of work it might help with your cabling issues?
Physics toolbox, I would imagine one of the tools on there would be able to record from your sensors and provide the data you need. Perhaps the g force tool?
Si vous voulez vous amuser il y a aussi des applis qui peuvent faire ça en direct sur smartphone: exemple
If you like playing with sensors, I recommend this app
I once had a phone with barometer; it was fun watching the pressure change when riding the elevator, going on plane trips etc
Physics Toolbox Suite has all tools for various sensors on your phone including the compass, GPS, accelerometer, gyroscope, light sensor, proximity, barometer, etc. Really a must have utility app.

I use Physics Toolbox Sensor Suite. In itself it's great but I would necessarily recommend it for this. But it works.
I think Physics Toolbox Sensor Suite by Vieyra Software might be a little bit more complete in regards to the sensor readouts it offers.
Just get a cheap android tablet/phone with an IMU and use a data logging program.
The kindle fire HD for example uses this invensense IMU that can output at 1000hz: https://www.invensense.com/wp-content/uploads/2015/02/MPU-6000-Datasheet1.pdf
and it's only 90 bucks!
There are a bunch of apps, take a look at https://play.google.com/store/apps/details?id=com.chrystianvieyra.physicstoolboxsuite&hl=en It allows you to record sessions and export data as CSV
I've been working on this problem for a while, and wrote an app that logs the data to a CSV file. This is pre-alpha status. It won't break your device or anything, but it's a little clunky.
My new favorite for just playing around with sensors is Physics Toolbox, and that will also log to CSV. I'm working on some more flashlight-specific features though.
Here are some useful things I've learned:
- The lux reading doesn't have much to do with actual lux. You'll have to calibrate it using known light sources. A Fenix light is usually a pretty good known light source
- I calibrate to measure candela by distance = sqrt(official candela / measured lux), then average it for several lights. After that, measured at the same distance, candela = measured lux * distance ^ 2. If you measured real lux, you could measure real distance, but you don't, so compute it using the readings and known values.
- An integrating sphere is ideal for estimating lumens, but a box will do OK. Try to make sure the light has bounced twice before it hits the sensor, as this mitigates the difference between different beam shapes. It's a fixed ratio between measured lux and actual lumens here, so just average the ratio over several lights.
- Some phones don't have a very precise lux meter. It might, for example have only three or four possible readings. Such a phone is not useful for this purpose.
I'm working built-in graphing and calibration profiles to make this app a lot more useful. I think I've also figured out a way to make a crude version of parametrek's beam profile tool using only the phone's sensors.
Physics Toolbox Sensor Suite will allow you to create a .CSV File to record the G-Sensor readings of the phone. You would need to start it and tap the "start" button to record the data. I tested it briefly and got some output like this:

At point 18:35:44:2 - this is where the dryer stopped. NOTE: My dishwasher is next to the dryer separated by a wall and it was running, so I would expect some data there well as the phone is highly sensitive. Your values will vary.
You can create a state with the app being open, and then monitor the .csv file it would create. I do not know right off the bat on how to monitor the file in real time, but it would at least be able to be a place to start.
I can see some issues with this though - in order to obtain the CSV file, you must stop the recording and give it a name. It allows you to create a filename of .csv or - No filename but with the extension of .csv
If you were to use AutoInput, it would allow you to create the start and end actions as well as give it a filename to save it by. Using Tasker, you can fire off the AutoInput Task to turn it on/off every few minutes or so, this will allow you to poll the .csv file for the lowest value in the "gFx" column.
With the value you look for being the right one, then you can fire off an alarm or sound task to generate noise.

There are others, explore.
For simulations, there's phet and osp.
I'm a fan of a few youtube series like minute physics, veritasium, sixty symbols, smarter every day, and crash course. Tom Scott and VSauce sometimes have good physics stuff too. I don't always show the videos in class: instead I've designed a few lessons to show the same thing.
There's a few demonstrations that I find work better than the typical textbooks ones. I find Barton's pendulums works better for showing resonance than tuning forks and those boxes. Alternatively a bass guitar hitting the right note is bound to make something in the room vibrate! Smartphones have good apps that often work better for me than lab equipment. I only have android, which has apps like Physics Toolbox, and Sensor Box Plugin for all-in-one toolbox which replace accelerometers, sound meters, magnetometers etc.
