Well I did release four long videos in April ... so I suppose I've been back, although of course from my view point I didn't go anywhere. Over the summer I created quite a few 45 sec or so videos, which will be RU-vid shorts, Tik Tok, Reels, etc. Am working on a longer video right now (12 minutes?) about the technology underlying color photography.
IKR!!! Bill, you've been gone for years man - I check YT every now and then but my last must have been before April. You've been missed. Great to have your content back. Hope you are well.
@engineerguy I appreciate that you're willing to work in a medium you're not naturally drawn to. And as usual you took your time to study it and produced excellent shorts that still have your signature style at their core.
Those are actually made up of multiple accelerometers, which are oriented in different directions. " True"X,y,z accelerations get calculated form measured values
A gryo would not be a good idea because it tells you about angular velocity, not orientation. You could do an integral on velocity to get your orientation, but that is going to drift like crazy and not be useful. If you hold a 3 axis accelerometer still, you will know exactly which direction gravity is in, and thus the orientation.
Look up photolithography, and prepare for a deep dive. Edit: More specifically, lookup MEMS (Microelectromechanical Systems), which uses photolithography.
As a side note, when your phone is immobile, the accelerometers are picking up a 9.81 m/s^2 acceleration up, and when your phone is accelerating in free fall, its picking up no acceleration at all. So in free fall your phone can’t tell which way is up.
Probably know's it's falling tho. Cause it could feel everything leading up to it and that weightless feeling would be foreign and uncomfortable like it is for us.
@@joblo2671once your phone has reached terminal velocity, it’s as if it were just sitting on the ground again. It will once again know which way is up.
@@joblo2671 The terminal velocity has nothing to do with it. It is an accelerometer, it measures acceleration, not speed. So, free falling means no acceleration. Do not confuse it with seeming acceleration from our perspective, we are in accelerating frame of reference, so it seems that falling object is accelerated towards Earth, however in General relativity it is the Earth surface that is accelerated.
@@dmitriy4708 what the hell are you talking about? I'm saying your phone would have to reach it's maximum speed of descent for the statement to be true. This would never happen if dropped from your hand or off of a table.
This guy is just brilliant Short, to the point and explains stuff we all use but don’t know how it works. Simple, clear and always very interesting Great stuff!
I love that this is your first video in this format and the topic is about a phone that changes its orientation. It's poetic and that poetry is not unnoticed

Breaking Taps has a brilliant video about this! He even 3D prints one and goes into detail on how it works.
Just replaying yo this video to say you are an amazing person and one of the most simplified explanations in the world. Dare i say simpler than varitasum
My mom had a phone that would turn the screen upside down in case the phone was upside down. It was a lifesaver while charging; if only newer phones had that feature.
These videos are palate cleansers. I watch 20 videos about crime, culture wars, "music" videos, just a bunch of total garbage and think man, pack it in, we are done for. Then I watch The Engineering Guy and feel like, oh, ok, there are still normal people doing normal things and teaching and making the world better.
Whats really cool about this to me is how wildy the aplication of a single desgin can change as soon as someone with a different perspective looks at it.
i kind of figured there was like a little ball that moves around with gravity and it detected the direction the ball is facing. Similar to how a joystick works, just with gravity
Woow.... I thought it was a gyroscope. Now, I know it would have to be tiny but the vibration is made by something spinning and so I thought they just made it happen and size wasn't an issue
That's why the screen always turns into landscape while reading in bed with the slightest tilt. But refuses to turn the other way around unless it is straight up in the air absolute precisely on every axis. because it thought the crash already happened and why bother to reverse it the same way.
