In the @BlackHatEvents Book Store you can find "Open Circuits" - a wonderful @nostarch book about the internals of various things by @oskay (buts psst: they only brought 15 copies, 6 left, two on hold... ๐)

I need a breadboard that fits all the newer microcontroller dev boards that are gigantic like the ESP32 Dev Kit boards or FPGA boards. I also just want more slots sometimes.
And every other column should be gray. ๐

here's a cool photo of a chip. this one is special because it's a real old-school photograph that i fed through my scanner.

it's a really crazy design, like there are differential signals going all over the place even with some length matching. gotta be at the picosecond level.

I received a mysterious aerospace computer from the early 1970s, probably for navigation. It is crammed full of flat-pack integrated circuits surrounding a core memory module. Let's take a look inside... 1/17

many of you are mourning the Z80 CPU (recently discontinued after a nearly 50 year run). all is not lost--i bet Rochester will take up the torch.
as according to the prophecy, Rochester will soon be the last remaining US semiconductor company.

fun fact! the numbers in coin cell part numbers are dimensions. a CR2025 is 20mm diameter and 2.5mm thick!

cross section of a high power electric car charging cable. the electric current is so high that the copper wires would overheat, but coolant flows through small tubes in the center of each wire.
