A dive into the tiny, silicon accelerometers and gyros in your phone
I thought the model of 3D printing models of the chips to be a really cool way of visualizing how these chips work.
From the YouTube summary
How does your phone track its position in space? MEMS devices! Phones use small micro mechanical chips called MEMS, to monitor accelerations and rotations. These are fabricated using semiconductor technology, but are tiny little moving mechanisms.
Today we're decapping a six axis IMU (MPU-6050, on a GY-521 breakout board, containing three accelerometers and three gyroscopes), looking at it under the SEM, printing up some models, doing some high speed video recording, and talking about how these little MEMS devices work.
CAD/STL models (fair warning, it's a very challenging print!): https://www.printables.com/model/413667-mems-model-six-axis-imu-device
Amazing video which must have caused a huge amount of preparation work. Thanks for sharing!
I also would love these prints. Great deep dive! Thank you for sharing this video!
This guy’s channel is so awesome, glad to see it posted here. He has all kinds of cool tools that he built in his lab like a scanning electron microscope. His videos on atomic force microscopes and laser lithography are really fascinating as well, he is really great at explaining the concepts too, definitely recommend!
Mmmmmmm... gyros.
