If you’re wondering how to fit a fitness tracker into a ring, well, you’re not alone. [Becky Stern] CT sent someone to scan, went into it with a rotating tool, and then he made a video about it. [David Cranor]. (Video is embedded below.)
While it’s great that you can tear down something these days without tearing it down – thanks to CT scans – most of the analysis is done in a cut-up version of the thing through a simple stereo microscope. Still, the ability to flip the thing over in a 3D CT scan is excellent.
We totally agree [Becky] And [David] It’s amazing how much was fitted in very few places. Somewhere along the way, [David] The electrical, mechanical and software design teams have certainly worked hard together to close this project and it shows. After all, there’s a nice running dialogue about how you know what you’re looking at when tearing up a new device, and it’s good to look at their shoulders.
Then where are the bits [Becky] A lithium-ion battery pack shows you what it looks like when cut in half. He said it was already mostly leaking and he did not explode in the fire. But get there easily! (Also, make sure you take your hot xylene outdoors.)
X-ray machines are definitely the greatest thing when doing a teardown. We’ve seen them use everything from fixing multimeters to servo motors.
