  • Yeah, I don’t see how this is a problem. I mean people make all kinds of things without 3D printing. Think of a Star Wars stormtrooper set of armor. People have been making those for decades, and selling them, before 3D printers took over some of the work. I’m sure IP is part of the reason companies want to regulate 3D printing, but I’d also be willing to bet that they want to do the same shit they always do - insert themselves in the middle and force you to pay for designs. Whether it’s a Mario bros. minifig or a replacement knob for your clothes dryer.



  • Go to a laundromat and use their machines or a wash/dry/fold service.

    Alternative:

    If you’re truly desperate to get away from public machines you can get standalone mini-washing machines that take up little room, and just hang-dry clothing on a collapsible clothes dryer. The washing machine can be sold to recoup some of the costs when you move. At $5-$8 wash load and 25¢/5 min dryer a load around me 20 loads would pay for a mini-machine. You can do laundry at your convenience, at home, and for cheaper as the machine sorta pays for itself in saved $.





  • It’s right there, friend.

    25,000lb. Reading the article it says “more than 25,000 lb”.

    We should assume they used a highly efficient airfoil that can maintain the most efficient possible cruise for the demonstration aircraft probably at L/D max if they’e looking for time aloft, so I doubt it’s even worth considering top speed or ceiling. It would be interesting to know what NACA profile they used and what the top speed characteristics would be.

    Edit: looks like a Vne of 140 Kias. This is not a fast aircraft. Also a minimal useful load. If you make a couple clicks through to the site of the test it’ll give you more info.


  • While knowledge like that is deprecated, the foundational skills and problem-solving it gave you are still very valuable. Modern systems are still built upon old roads, so people with this base level of knowledge have a far easier time sorting out what fixes are needed. Like being an old mechanic that diagnoses a car issue almost immediately because they can hear the issue without hooking up a digital diagnostic, they already know what to look for.

    I miss older computers, lol. 2000-2010-ish was the golden era.



  • The vast majority of higher math and some industry-related chart interpretation as far as aviation goes.

    I guess I’m probably older than 95% of the people here, so all the “spaghetti” charts we had to figure out, the actual trigonometry used to calculate wind correction angles, all of the math used to calculate EPR, thrust, and Mach speeds. Instruction in these calculations was very demanding and unforgiving. Then it all pretty much became useless as I followed the leading edge of software development and electronics moving into the cockpit. So I learned it all only to have it disappear within a few years.
