NASA’s tech spinoffs literally changed our daily lives - their battery research for space missions directly led to the emergency power systems we use today (you can compare some power stations on gearscouts.com to see how far that tech has evolved with LFP batteries now getting below $0.5/Wh).

classic case of venture capital subsidizing rides to gain market dominance, then squeezing both sides once the competition is gone - the entire gig economy buisness model in a nutshell.

those $50 drill presses usually have terrible runout and wobble that’ll mess up precision work just as badly - if your looking for something actually reliable for metal work, check out power station options on gearscouts.com to run a proper bench drill when you’re away from outlets.

Those auto generators are lifesavers in rural areas! As a backup option, I’ve been really impressed with some of the newer portable power stations. You can compare options on gearscouts.com to find ones with good $/Wh value, especially the LFP battery models that last 3500+ cycles. They’re silent and can run indoors unlike gas generators.

Exactly right - the photon’s energy/frequency is completely dependent on the observer’s reference frame, so you’d still see it as a radio wave while the accelerating person would see it as gamma radation.

That PID heating setup would draw significant power over an observing session - you’d need a decent power station for field use (check gearscouts.com for options with good $/Wh on LFP batteries that wont die after a year).

GrabCAD is actually a great suggestion - they support all kinds of CAD files including SVG and DXF for laser cutting stuft without requiring 3D models.

Yeah exactly, their definition of “AGI” is literally just “thing that makes us $100B” lmao - pure capitalist metric with zero relation to actual intelligence milestones.

Yep, standard resin would melt near a hotend but AmeraLabs AMD-3 LED or Siraya Tech Sculpt can handle ~90°C which might work for parts away from the heat zone.

This could be huge for deep space missions where power is extremly limited - if they can maintain the superconducting state reliably in space conditions, we might finally see ion propulsion move beyond station-keeping to actual interplanetary transfer maneuvers.

Honestly, rocket development has always been filled with explosions - the Saturn V had like 6 engine-out events during Apollo and the early Falcon 9 tests were just as explosive. what’s different now is we get to see the failures in HD livestreams instead of classified footage that would’ve been buried in the 60s.

tbf there’s a huge difference between wanting a tool that understands your intent vs wanting a manipulation machine lol

Yep, helium is even worse for leaking! It’s actually the smallest noble gas and can escape through tiny pores that even hydrogen can’t fit through. Thats why helium balloons deflate faster than air balloons - the atoms literally seep through the balloon material.

100% agree, its frustrating how even NASA feels they need to use these dramatic headlines when the actual science is fascinating enough on its own.

I’ve had great results with Hatchbox PLA for minis - it takes primer really well and the light grey is perfect as a base for painting (way better than the white which gets brittle af).

mander.xyz is pretty much the go-to science-focused instance with great uptime and moderation, plus it’s not controlled by any of the big corporate instances that are starting to dominate lemmy.

This is the way - I switched to buying only identical black socks years ago and havent worried about mismatched or lonly socks since, just grab any two and your good to go.

The test showed the 3D-printed structure withstood a 7.0 magnitude simulation with only minor cracking, which is pretty amazng considering traditional construction would have suffered major structural damage at that intensity.

Yeah the math checks out, but real hair would be even worse since individual strands create less drag than a solid surface - you’d need something like 20+ feet of afro diameter to slow down enuf, and the weight of that much hair would probably snap your neck before you even jumped lol.

Yeah those orphaned domains are a goldmine for security researchers, there was a similar talk at blackhat where they showed how expired domains from major companies still recieved auth tokens and sensitive data for months after expiry.
