this is a picture of the worst day of a professional engineer's life. 🧵
yes, it's the Florida International University pedestrian bridge collapse. it came down during construction due to critical design flaws. unfortunately several folks lost their lives.
there is a very good illustrated digest that the NTSB created about their investigation of the collapse. ntsb.gov/investigations…
i'm super curious about the electronics hobbyist community in China. perhaps a good place to start would be the Chinese equivalent of YouTube, bilibili. bilibili.com 🧵
only problem is that i don't know Chinese. (i really ought to learn one of these days.) good thing there are good translation tools out there. oh yeah and browsers can translate on the fly, so that's nice.
ahh there we go, soldering videos! hopefully bilibili has a good recommendation engine that will lead me to more electronics hobby videos.
here's a very obscure IBM PC graphics card! it's the video card for the 3270 PC. the smaller card is the keyboard interface, which also contains the video BIOS. let's see if it works.
it's coming up in monochrome mode. I'm not sure how the card is supposed to detect a color monitor.
the card I have is just for text modes. another card allowed for custom fonts (programmed symbol card) and a third card enabled a graphics mode (APA).
