i reverse engineered the effect a few years back. xitter.cf/TubeTimeUS/status/1297โฆ
so my friend @compgeke has this computer with a really neat VGA BIOS screen: there's a rainbow shimmering effect on the logo! ๐ but how does it work? (๐งต...)

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
my housemate in college bought a Kitfox that was about 80% completed, and stored it in our garage diagonally (it barely fit!)
after cleaning a couple of dirty contacts and freeing up the solidified grease on the subtract pawl here on the coin unit, the machine works again!
these old electromechanical pinball machines are tricky to work on. (yes i am aware of the Technology Connections video)
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.
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.
