;tell ferram4 im planning to build a small hybrid rocket engine and I need help with the nozzle design, I was told that you could help in that

Humm, Ellied, what would you do if you had a 3.3v supply and a device that needs 5v? I am looking at currents below 100mA, so that should not be a requirement
<Ellied>
I would probably just look for a 5V supply TBH, they're very common and building a boost converter to go from 3.3 to 5V would be a ton of effort compared to just buying a cheapo 5V supply somewhere
<APlayer>
Does this look acceptable? https://www.pololu.com/product/2562/specs Because I have no access to 5v in this case, I am powering the whole thing (that drone project I mentioned a few times) from a 3.7v Li-Po cell
<Ellied>
~sf..
<Ellied>
disregard that
<Ellied>
APlayer: that would work, but would it cost less than just another battery in series and a linear regulator?
<APlayer>
It would weigh more
<Ellied>
true
<Ellied>
that regulator seems pretty good
<APlayer>
What would a linear regulator do, though?
technicalfool_ has quit [Ping timeout: 198 seconds]
<Ellied>
a linear regulator is just a magic resistor that adjusts its value to keep the voltage at one end constant, basically
<APlayer>
Ah, got it
<Ellied>
It's not very efficient, but the output is very stable and they tend to be cheapish
<APlayer>
Efficiency is another thing I care about
<bofh>
Oh, are there compat issues between Principia & RSS?
<egg>
bofh: no, it's just that RSS has been stuck in 1.2.2 for ages
<egg>
bofh: so I'm trying to get it moving
<egg>
bofh: and they work extremely well together, we even choose our default integrator for the real solar system :-p
<egg>
bofh: also, RSS at current master has Vesta, Ceres, and the moons of Herschel, finally
<egg>
bofh: note that not only is Principia RSS-compatible, RSS looks weird without it (because no axial tilt in stock, so the moons of Saturn don't align with its rings)
<soundnfury>
Herschel? ITYM Georgius Sider... uh... -us? /me cannot into Latin
<bofh>
the moons of Herschel being Saturn II-VII?
<egg>
bofh: Herschel, the planet that comes before Le Verrier in the order of increasing distance to the sun :-p
<soundnfury>
sorry, that should have been Georgium Sidus
<egg>
yes, it's George's star, not George of the star nor George by the star or whichever case and number you were going for
<soundnfury>
like I say, /me cannot into Latin

TIL shared_ptr isn't thread-safe
<egg>
awang: uh wat
<egg>
awang: ah you mean a single shared_ptr
<egg>
awang: but it's safe to poke at different shared_ptr managing the same objects from different threads
