This key is for a car you can’t get in the US. 👀
We CT scanned a BYD key fob used across their lineup. Almost every part is BYD’s own, except the Panasonic coin cell in the middle. Does this design closely resemble your car key?

RAM prices have gone crazy with AI data centers disrupting the entire market. Some PC gamers are going back to DDR3 RAM and older components for their budget gaming builds. 😮💨
We CT scanned a 4GB stick from a 2014 gaming PC to see what’s inside. Would you build a budget rig with older parts or just pay up for the latest DDR5?

We CT scanned a 4GB stick of DDR3 RAM from a 2014 gaming PC to see what’s inside. Would you build a PC with older parts instead of shelling out cash for a brand new system?
BYD, the Chinese EV manufacturer, delivered 4.6 million vehicles in 2025, making it the world’s largest electric vehicle maker by volume.
Americans mostly know the name from trade headlines around tariffs and national security investigations. What gets less attention is that BYD manufactures roughly 75% of the components inside its own vehicles, a level of vertical integration not seen since the inception of Ford. It’s a sharp contrast to American automotive manufacturers who rely on a network of suppliers.
Our latest Scan of the Month covers four BYD parts: a lithium iron phosphate battery cell, a window switch panel, a portable EV charger, and a key fob. Follow our link in bio to scroll through the scans to see what the world’s largest EV manufacturer is building. 🔗
It’s been a while since any of us have used one of these. 👀
We CT scanned a 32GB USB stick to see what’s storing all of our old homework. When was the last time you used a USB stick?
Jon and Alex get into why complex systems demand more attention through the lens of normal accident theory: as systems become more tightly coupled, accidents become inevitable. The Challenger is the textbook example. The O-ring had been damaged on previous flights without failing, and that history of getting away with it is what made complacency easier.

Counterfeit products are flooding the global market and tariffs are making the situation worse. In our survey of 210 manufacturing quality leaders, 62% said the volatile tariff landscape has made quality harder to ensure, and 27% reported suppliers outright lying about country of origin or original manufacturer to evade tariffs.
The full Lumafield Cost of Quality Report breaks down how leading manufacturers are getting ahead of the problem and benchmarks how much quality costs across industries.

The Artemis II crew tested manual controls of their spacecraft last month using controller designs that trace back to the Apollo missions. We CT scanned two Apollo hand controllers to see how they work. (Thanks for letting us scan these !)
The Translation Hand Controller moves the spacecraft through push, pull, and side-to-side motion. A twist counterclockwise during launch triggered an abort and fired the Launch Escape System, while clockwise overrode the Apollo Guidance Computer and handed control to the backup system.
The Rotation Hand Controller handled pitch, roll, and yaw with a pitch axis that pivots at the center of your palm rather than down inside the stick. And there’s a trigger for push-to-talk for ground communications.
Swipe through to see the scans of these historical controllers. 🌕
The first stereophone was built from cardboard and foam in 1958. Nearly 70 years later, the mechanical principle behind a driver hasn’t fundamentally changed, but everything around it has. Smaller drivers, lighter enclosures, and active electronics doing jobs that acoustics used to handle.
Our newest Scan of the Month covers four headphones from $80 to $550 to show what that trajectory has manifested into. Follow our link in bio to scroll through our latest Scan of the Month.
The Artemis II crew tested manual controls of their spacecraft last month using a layout that traces back to the Apollo missions. This Apollo Translation Hand Controller handled position changes in space through push, pull, and side-to-side motion, but the twist mechanism had its own twist. Counterclockwise during launch triggered an abort and fired the Launch Escape System, while clockwise overrode the Apollo Guidance Computer and handed control to the backup system. Would you be able to remember the difference between twists?
