  1. Well, that explains all the failures. It is universally agreed that Jeb's Junkyard is one the best examples of the triumph of unwavering motivation in the face of seemingly insurmountable odds. The unassuming junkyard where it is said some of Kerbalkind's first steps towards the depths of space have been taken, has now become a much larger junkyard, as it had to expand its facilities to accommodate the ever greater demand for spacecraft components. Jeb's Junkyard has become one of Kerbin's most iconic names, becoming far more than just a beloved brand. It now stands proudly as a symbol of the unstoppable Kerbal drive towards attempting the impossible while grossly underestimating the gravity of the situation. You'll have to excuse the spoilers, posting via mobile is still broken and barely half functional.
  2. It would still take thousands of Starships to build and furnish the thing. He's talking a lot about the outer shell, but just glossing over the interior, and most of the work is on the inside. Sure, it would be a lot easier to work on it once the thing is pressurized and spun up, but look at the building process of any large building down here. The structure goes up quickly, but that's just a fraction of the work that needs to be done.
  3. Delusion of the guy is fascinating. Two weeks to build the entire thing (13:45), or is it a month? Not like it matters in either case. No way. At least he finally woke up and realized that worldwide lottery is never going to fly (at least he hasn't mentioned it in this video). He mentioned sun-synchronous orbit (12:55), so his Starship cargo numbers are not accurate.
  4. Yep, it seems like humanity's going to get a whole bunch of never seen before pretty pictures, and likely some brand new science points.
  5. I tried to convince my family to properly season one cast iron skillet which came "pre-seasoned" from the store. They reluctantly agreed, so I started the process. Five minutes later "Why is this taking so long. I need the pan.".
  6. No need to deplete it. It's just as dense* in it's natural mix. *close enough not to matter for this discussion
  7. It's a significantly shorter list of sequels that should not be ignored: Terminator II: judgement Day
  8. SpinLaunch seems to have signed some sort of deal with NASA to yeet a 3 meter long payload on a suborbital test at about Mach 2. Landing using a parachute. Mach 6 test later this year. https://techcrunch.com/2022/04/06/spinlaunch-scores-nasa-test-mission-to-demonstrate-its-unique-launch-method/?guccounter=1&guce_referrer=aHR0cHM6Ly9lbi53aWtpcGVkaWEub3JnLw&guce_referrer_sig=AQAAAJnLpVqzVWpYhVVxUdk6m6ZzJ_vcqB7-DtOxclaLBRDSVD9HHRWWgEsvQpO4VDu7l0hbgqh0gqLphklv9Kd_fozgEgk0j-1217Wo6u0CXNTJJw76VSHB5MEZkwCd0R4mbheHM0m8tKl4Bq9PKCzuG5QsIv0TwjMIxCc1G80aX2Zm
  9. "That would be you, if I don't get that ring, pronto!" Had to google it to check, but this exchange stuck with me for 20 years.
  10. Is it me, or the test fire out of the back of the trailer seems unstable, as in pulsing (bot high frequency brrrrt and occasional stutter)? They are getting some shock diamonds, but the lengths of them is all over the place.
  11. I would asume Leidenfrost effect would prevent sufficient contact with water, leading to cooling being too slow.
  12. That's it! You people are awesome.
  13. I suppose this is as good a place as any to ask this. My memory is a bit fuzzy on this one, but I'm looking for an SF novel/short story that possibly starts out with a ram scooper ship skimming Earth's atmosphere to replenish the LEO space station's air supply. The setting is, IIRC, post apocalyptic/fall of civilization so the space station is in dire need of air, but can't rely on resupply missions from Earth. The skimmer ship crew (one or maybe two individuals) were born on the station, have lost most of their muscle mass and can not walk by themselves, once the eventually crash land, because the ram scooper is an old piece of junk... something something about landings and walking away from them. The crew is then rescued by a local underground space fan club while the government agents (???) search for them. Apparently there is some feud between Earthlings and space station dwellers. Does this ring a bell? My guess is it was written by one of the big three, but really have no clue. Any guesses?
  14. Soldering this would be significantly easier if the board had soldermask, but making it in home shop is less than trivial. For home etching I had decent results with both toner transfer (printing on vinyl stickers, then transferring) and positive UV dry film (printed on transparency). The datasheet for the above recommends 0,3mm wide pads, but I'd go with 0,2 pads and 0,3 gaps, then fan out the traces and thicken them as soon as possible. It would help with ensuring no shorts in copper and easier soldering. If you don't want to have them made professionally, perhaps something in a bigger package would be better option simply for the ease of soldering and making the board.
