yeah "steam powered" is basically pneumatics but you use fire and boiling water instead of a compressor or vacuum pump because it was way easier to boil water than create a vacuum turbopump or compressor if you are restricted to 19th century manufacturing tolerances and materials it's pneumatics but way easier for things to get rusted and corroded because everything has loving steam in it and then it will get stuck and then it explodes because of all that pressure and even after it explodes it covers everything in a mixture of scalding water and fire

even more cool is how far we've come with miniaturizing steam power i mean you can make a steam powered iphone charger now that will fit on your average kitchen table

unless you are talking about hypoid gears and that's just basically magic

Jonny 290 posted:guys give us thirty five thousand dollars to put an arduino in space* lol at consumer grade electronics in space. they say they're sending up multiple arduinos for error correction but all the censors built with a normal bulk silicon process will also have latchup and flipped bits all over the place so good luck with that.

NotHet posted:are you really going to get many SEUs in a LEO? If they're in a polar orbit u may worry about the saa but even then its like 1 every 15 days or something. I found a neat graph:  For $35,000 i'm sure they can add whatever redundancy and watchdog/failsafe poo poo they need, but i question how often you'll have to reset everything, especially if there are sensors that have no redundancy or error correction idk i dont make space parts, i just know that everyone who does uses an soi process and actually shields things
