  • It might be too outdated to do major services, but it's still fine for its original use - interfacing with electronic components.

    You could build a weather station, monitor temperature and humidity in your attic and crawlspace, automatically water plants, etc. You don't need much electronics knowledge for that sort of thing.

    This pissed me off so much when I was a trucker.

    Businesses don’t have to let you park in their lots. Cities can put up no truck parking signs. States can restrict parking on entrance ramps.

    Stop giving them excuses to do so! You’re just making things worse for drivers out of sheer laziness. Truck stops let you throw away your trash in dumpsters.


  • High school? Chemistry. I took it because I had no interest in biology. Turned out to be interesting, so much so that I took Chem II even though it wasn’t required to graduate.

    Chem II was the hardest math class in high school. I loved it.

    College? Computer Organization. It’s about how computers work down at the circuitry level. All the programming was in assembly. Easily the hardest class I took in college.

    I don’t know why the hard classes were always my favorites.





  • Power efficiency and the amount of components you can fit into the same area are the big reasons.

    3nm isn’t what you use for regular run-of-the-mill chips like voltage regulators and ADCs. It’s for things like processors, where you have a metric buttload of complexity all in a tiny package.

    We can’t really clock silicon much faster than we do now, so speed increases come from having more cores, more pipelines, and more complicated tricks that let you do more with the same clock speed. People don’t want to buy new devices that aren’t faster than their old devices.

    Taiwanese fabs have pushed the state of the art for quite some time now, so if China is catching up then that will get some people’s attention. But Chinese fabs generally don’t participate in the global supply chain so I personally think it’s not going to have much impact in the west.
