I design electronics, mechanical stuff, write a bit of firmware and software, and consult.

Decided to try a little experiment - zooming in from 15x to 100,000x in smooth progression. The SEM isn't particularly well calibrated so the result is only ~30-40nm resolution, but I think it's still pretty neat. Working on making SEMs so affordable you could have one at home :)

@sailaunderscore Darien is a no-brainer. Parachutes glide really well, open as soon as you drop, glide to the nearest road or if lucky, right to Panama city or Medellin. If unlucky, still not IN the gap. Give the first driver you see $500 to get you to an airport. You'll be in NYC in under 16h.

@PAstynome Keyence may be great to work at, but they are AWFUL on sales and support, at least in the west. You leave your email with them *once* and you will never stop getting hounded by the sales people. But if you dare ask for support for an older/second hand product? Haha, pound sand.

@RyanAlimento Imagine these bad boys in your lungs, more like.

@FossilizedCum @pebblesdapibble @glnott @trashjuicecube You're getting ripped off. You can get a cheap mini-split for between $600 and $900ish basically worldwide. Most of them even allow for no-vacuum installation(just attach pipes and open the stop valves), though you shouldn't, since it reduces efficiency. Trivial to DIY install.

@boxcardavid I was doing it with a permanent marker when I was 9. But he says he's shipping 4 products per month, so it's all just performative BS anyway. Minimum worldwide certification turnaround is about a month and 2-6k in a Chinese lab.

@MarcoReps "A teaspoonful of aromatic spirits of AMMONIA in a small glass of water, hot coffee, or hot tea", yep, that will sure wake anyone up, it tracks. Not sure for how long though...

@ndawg_4 It can't be the reason your service system clogged/got destroyed because there's literally a hair thin capillary in the system to create the HP/LP section pressure difference for the cycle to work at all. That would be the first thing that clogs, which it clearly does not.

@eigenlucy If you can afford a dedicated librarian+admin(full time!) that will wrangle the projects across multiple people, and you need extremely complex multiboard assemblies, kind of, maybe. Their rentseeking has gone nuts lately. Used both professionally, prefer KiCAD for small teams.

[Andrey @Spirit532_]

@JasonPremoMFG @gak_pdx So you're going to end up with a $7995 printer instead of a $799.95 one, and no one will ever buy it because they can buy ten from elsewhere. Nobody wants that.

[Andrey @Spirit532_]

@janekm @lauriewired You are absolutely correct.

[Andrey @Spirit532_]

@damned_docs And you know what the best part is? They'll see this post. But what they'll take away is that they need to add that specific board as a known example, so when *they* try it, they'll be able to show you up by saying "You can't use it right! It identified it perfectly, see?!"

[Andrey @Spirit532_]

@eigenlucy I have been judged! Like a book, by the cover(pfp)! Feel free to ping when you're hiring. I do a lot of everything :)

[Andrey @Spirit532_]

@_baldtires The cost to build a modern large volume, large area display panel fab is in a similar ballpark to a state of the art i-line silicon fab. And most of the equipment is made by an obscure Japanese company in a shed somewhere. Lead time is YEARS.

@hiarcos Show me your portfolio and I'll think about it.

@davesnetvault If you've got something actionable, I'm always happy to chat. My DMs on here and email (see website) are open.

@mfbridge @fdotinc Or anyone who's finished a basic intro to... physics & chemistry, learning energy scales? I don't know if this even qualifies as thermo or something. You could 3D print a house from solid granite if there was a megawatt turbine genset with an olympic pool of kerosene nearby.

[Andrey @Spirit532_]

@davesnetvault Happy to accept the challenge, just have to find someone happy to accept the hole in their bank account too. Good science ain't cheap.

[Andrey @Spirit532_]

@davesnetvault Bench-sized TEM with CryoEM, that's one heck of a dream! The HV tank even at 120kV would be chunky on its own. It's certainly not impossible to make something the size of a compact fridge, but I'd estimate retail at $60-90k minimum, not cheap. NanoMi is just bizarre & expensive.
