This is the first time a book I've contributed to has gotten the subway platform publicity treatment.

As activity from the bees and other pollinators winds down, I'm reminded that sometimes it's nice to focus on the flowers without all the distractions. #bloomscrolling
Closeup of bond pad on a PIC12F683 after etching off the Cu ball bond.
Gold: overglass sealing the edges of the bond pad
White: Al bond pad surface
Tan: Barrier/adhesion layer under the Al, likely TiN (more likely) or sometimes TaN
You can clearly see the imprint where the bond wire (etched off during decap) squished into the pad and squeezed the aluminum out around the perimeter. The middle area either got thinned down mechanically during the bonding process, or form…

We made a gap for the arbutus tree to grow into :)
New fence posts always remind me of soldiers when they have the supports holding them up.

Did I mention IC reversing is absolute crack for AuDHD brains?
I should probably put down the EEPROM, at least for a while, and move on to other stuff. But I'm having too much fun.
This is the dangerous part, and the part I have the most trouble with... the problem is so big you'll *never* be done (especially doing it manually without any automation, figuring out what each cell is by hand, etc).
There's always more to discover. Nerd sniping to the 20th power.

Continuing work on the PIC12F683 video. Ripped out all of the early rambling guesswork floorplan analysis I did on the top metal and replaced it with a much more in-depth floorplan discussion looking at the substrate-level floorplan.
Video is now just shy of an hour 20 in length and I still need to add:
* Quick intro to digital CMOS layout and standard cells (planning to film this tonight)
* Deep dive on SRAM
* Deep dive on flash
* Deep dive on fuses/configuration…
