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
these old electromechanical pinball machines are tricky to work on. (yes i am aware of the Technology Connections video)
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.

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
ALT A compact aerospace computer with a numeric keypad and digit displays on the front. A circuit board with multiple flat-pack ICs is visible.
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!
ALT a digital caliper measuring the thickness of a coin cell (2.5mm) but the caliper is made of metal, obviously shorting out the coin cell.

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.
at the last Electronics Flea Market (in September) i found a strange bit of electromechanical aircraft avionics. check it out! mastodon.social/@tubetime/11โฆ
most recently, i reverse engineered a rare Apple II sound card (a sampler) using some blurry photos AND ARTWORK ON A RECORD ALBUM COVER!! mastodon.social/@tubetime/11โฆ
