Texas Instruments CD 40106 B | Schmitt Trigger from 1999. Marked the pinout according to TI datasheet. Bought this on eBay, decapped to see if it was original or Chinese fake. This is definitively original TI.

SIM Cards, the mysterious Java card OS systems used in our phones. Old 4G card I'm going to decap today.. This will be a multiple post decapping procedure so stay tuned ๐Ÿ˜›

I managed to remove the SIM card from the PVC body but what a surprise! It has anti-tampering plastic reinforced block ๐Ÿ˜… Can it stop us? Let's find out ๐Ÿ˜Œ

Look like we have a bigger SIM chip here, let's hope I can remove it intact. "A little progress with anti-tampering plastic, I managed to separate it from the gold metal contacts of the SIM"

Finally we can see the SIM card chip ๐Ÿ˜ A lot of memory there and some type of microcontroller core in the middle. Would be fun to photograph this ๐Ÿ˜Œ

Finally here it is.. The 4G SIM Card chip, probably running Java Card OS. It has a lot of memory and pretty dense core. oracle.com/java/java-card/

Now we understand why NSA with a bunch of people is pushing for Rust in Linux! ๐Ÿ˜… Is the Rust compiler really secure? ๐Ÿค” youtu.be/Fu3laL5VYdM?siโ€ฆ

The smallest camera sensor I have ever photographed. Probably 640x420 pixels.. So tiny ๐Ÿ˜„ Extracted from 30โ‚ฌ Alcatel GSM phone.

Day shot.. The vision perspective of an ant ๐Ÿœ "Black anodized heatsink with illumination from the top" Looks like a portal ๐Ÿ˜„ Enjoy.
