<SilverFox> So I'm learning heart murmurs and heart sounds and shit, and it's all just sound, which is a waveform, which can be analyzed. This makes me think that if we can record and normalize the sounds, we can compare them against norms and murmurs and see which matches the most and there ye go

<FoxBot9000> yt: Mitral Stenosis- normal speed | Thinklabs
<SilverFox> this is mitral stenosis, and shit gets fucked with the mitral valve, leading to weird flow of the blood, creating those series of wiggles before S2
<SilverFox> it sounds like laboured breathing of the heart

<SilverFox> S1 and S2 are very distinct sounds here with a small trail from S1

<SilverFox> Greys, 3d printer that hangs from the fucking ceiling
<SilverFox> the room is the build volume
<Greys> I know I've seen large scale triple tether systems, basically delta printers you string up wherever
<Greys> then there's that cement house printer, it's a delta system
<Greys> somebody aught'a make a desktop thick wall pumpable viscous fluid printing system
<Greys> something you could provide with a vat of wet plaster and it'd print you a real pot
<kmath> YouTube - Live: Building the Hangprinter v3 with Torbjørn Ludvigsen! (2/2)
<FoxBot9000> yt: Live: Building the Hangprinter v3 with Torbjørn Ludvigsen! (2/2) | Thomas Sanladerer
<Greys> that looks like something you could make if you can get any of your printers running
<SilverFox> I have nowhere to set it up
<SilverFox> it would be fuckin sweet, I could make a business of 3D modelling and printing people
<Greys> actually, I bet the majority of what is printed in that build doesn't need to be printed, you could probably halfass this out of wood and screws for the most part
<Greys> the speed that thing is going, a person would take all day
<SilverFox> yeah, but I could also charge lots because of it
<SilverFox> and this is just the first time it's being set up
<SilverFox> so tweaking and shit can be done to get things done faster
<Greys> you'd need somewhere you can set up five; but also you could place the tethering differently to make it fit in a 6ft square, maybe less
<SilverFox> why five
<Greys> parallelism
<SilverFox> no
<Greys> five is an arbitrary number
<SilverFox> very
<Greys> yep
<SilverFox> there's no reason right now for parallelism
<SilverFox> if I can print it all at once, I can do that
<Greys> the problem with tether deltas and speed is you have to keep the momentum super low; but you don't want the inertia to be too low, because inertia adds stability; I'm sure this is true for all designs but with tether deltas in particular it's a lot worse
<Greys> so that thing can only go so fast before it can't be controlled accurately
<SilverFox> well yeah
<SilverFox> that happens with anything
<Greys> it's much worse when tethers are involved
<Greys> if you rescaled it to operate in a 1.5m~2m square, with the goal of printing people; you could fit 4~6 of them in a typical american garage
<SilverFox> people aren't 1.5m wide
<Greys> one problem is going to be the arms, you're likely to have the lowest point on the arm be floating in space, that would be a lot of support material
<Greys> the volume of the machine, not the print area
<Greys> print area is always smaller
<SilverFox> or you can pose the arms so that isn't a problem
<Greys> everybody put your hands in the air?
<SilverFox> or by your side?
<SilverFox> like, just relax them?
<Greys> so you've got two poses that'll work
<SilverFox> also, any pose with elbows higher than shoulder will work
<Greys> does overhang performance improve with nozzle size?
<SilverFox> dunno
<Greys> seems like a thicker bead would be better at overhang
<SilverFox> maybe
<SilverFox> maybe it'll be worse due to mass
<SilverFox> it all depends on the filament as well
<Greys> what you could do is have some calibrated stands that you have people pose with their lowest-arm-point on; then when the print gets to teh first layyer of that island you put the stands in the print area to give a secondary bed
<SilverFox> that's gonna be jank as fuck
<Greys> deffinitely, but it greatly increases your viable poses, while being much cheaper
<Greys> you could have the print be one-handed leaning on a post; then they just need to get a suitable thing made to replace it in the installation
<SilverFox> well here's the thing, the arms are at least past the 50% mark on a print
<SilverFox> having jank on first layer is k, because it takes like, 2 minutes max to fix
<SilverFox> but when you're on a 24 hour print and halfway through it gets fucked
<SilverFox> you know that steve jobs pose? that's viable
<Greys> so you can only print people with their hands in a pocket, or elbow above their shoulder waving
<Greys> I don't know it, got a pic?
<SilverFox> nigga
<SilverFox> ye
<SilverFox> with arms crossed against lower chest
<SilverFox> as long as it's flush with the body, it should be viable
<Greys> if you were just doing a bust; which might be a good gateway product, smaller, more limited, but less restricted; but his elbow is going to be an island
<SilverFox> and bridges that are slower, are more viable
<Greys> there are very few pictures of steve job's whole torso....
<SilverFox> the flusher the pose, the better
<SilverFox> T-pose would be a fucking holy grail
<Greys> now, a 3D printed person is neat, but then using the print to create a casting in a better material would be a lot more valuable
fcbayerndm has joined #kspmodders
<Greys> particularly a wax print could be used for metal casting
<Greys> how much electricity does a 3D printer use?
<SilverFox> depends on if it has heated bed, this one doesn't, so something like, 100W maybe?
<SilverFox> also, lets just stop being retarded and print it in two or three pieces
<Greys> if the operational cost is low, then investing in multiple limb-scale printers and putting the person together barbie style would be faster; it'd be more work to maintain six machines but it'd also be faster
<Greys> 4 limbs, torso, head
<SilverFox> yeah or just to start, cause these machines are fucking expensive, just separate the print
<Greys> separating the head lets you have a smaller torso printer, and allows you to print the head in greater detail
<Greys> you're going to build all of them aren't you?
<SilverFox> the fuck you mean all of them
<SilverFox> there's only one
<SilverFox> I would only buy one, because I dont have the space for multiple
<SilverFox> look at the video and see how fucking huge it is
<Greys> yea whatever; of the N that exist for N>0, you will build N of them
<Greys> oh yea if we're barbieing that printer's useless
<SilverFox> wouldn't say useless
<Greys> a rigid printer of any design would be faster and more accurate, the advantage of the tether delta is print area, which isn't important with separated limbs
<SilverFox> every piecing process creates seams and grossness
<SilverFox> like, we still need a decent print height for limbs and shit
<Greys> but we don't need much area, all height
<Greys> so a tall rigid delta would work great
<Greys> and it'd be the size of two minifridges stacked instead of a sixth of your garage
<SilverFox> hey Greys, here's a great idea I had
<Greys> suck a dick?
<SilverFox> you know how expensive it is to see a cardiologist?
<Greys> I haven't seen any doctor in more than a decade
<Greys> no
<SilverFox> mmmmmmmmkay
<SilverFox> doctors are supposedly espensive to see
<Greys> is it particularly more expensive than other kind of doctors?
<SilverFox> so you know those BP cuffs in pharmacies?
<Greys> yes
<Greys> they're horrible now
<Greys> this higi company bought them all and now they're calibrated to crush the fuck out of your arm and still provide irrational readings
<SilverFox> there are electric stethoscopes that can show you the waveform of the heart sounds
<SilverFox> I don't think that happens but mkay
<Greys> so like a stethoscope with a microphone diaphram instead of ear pieces?
<SilverFox> yes, but not exclusively
<SilverFox> there are ones with both
<SilverFox> mkay?
<Greys> every BP station I know about, except walmart, has been replaced with something from this brand; and every one I've used is unreliable and painful
<SilverFox> okay wait
<Greys> what's worse is they retrofit existing machines most of the time; and I had used several before they were higi'd, they used to work fine
<SilverFox> what do you mean by "unreliable"?
<Greys> they put the pressure up so high that it induces a response and causes the body to be different
<Greys> if an old person used one of these they'd definitely get hella bruises
<SilverFox> "induces a response and causes the body to be different" you're gonna have to specify here
<Greys> imagine I tried to take your heart rate, in the way you know to do
<Greys> but then replace the step before actually counting anything with punching you in the face
<Greys> the measured heart rate will not be real
<SilverFox> well you see, it'll be real
<Greys> it'll be momentary
<SilverFox> there is no fake heart rate
<SilverFox> but uhh
<SilverFox> machines usually overinflate, so yeah
<SilverFox> what do they inflate to?
<Greys> what do the numbers normally look like
<Greys> I stopped using them because they're all fucking higis and I don't want my arm to hurt
<SilverFox> I can't tell you what they normally look like, there is no normal, I'm asking you what you're seeing
<Greys> it's been over a year
<SilverFox> in order to measure bp there's a process for it
<SilverFox> bp machines skip the first half or some shit
<SilverFox> although, they might've gotten more sophisticated by now
<Greys> last time I used it; and it's been a long time; it went up to about 170, and then down to the reading of about 140
<Greys> and it didn't go up progressively
<SilverFox> did it inflate slowly?
<Greys> about as slow as I'd expect the machine to be capable of
<Greys> it didn't take a bunch of steps; just shoots straight up without question
<SilverFox> it shouldn't take steps as a machine
<Greys> they used to
<SilverFox> it can pump continuously and taking steps can lead to inaccurate readings, smaller steps that iss
<Greys> what unit is this in?
<SilverFox> units dont matter here
<SilverFox> they should all be the same
<Greys> out of curiosity
<SilverFox> mmHg
<Greys> ah right, that makes sense
<SilverFox> millimetres mercury
<Greys> 170PSI would be insane
<SilverFox> you'd explode
<Greys> "Welcome to our self service amputation machine"
<Greys> but anyway, if you ramp up to 170 immediately, in the timespan it takes to drop down to the readings the patient's bloodpressure is going to retaliate and the reading will be substantially higher than th enumber you're attempting to measure
<SilverFox> doing it as quickly as possible is best, since leaving it on for longer periods of time will give inaccurate readings and will cause numbness of the arm
<Greys> numbness check
<SilverFox> taking BP literally cuts of circulation
<Greys> yes
<SilverFox> it'll go up quickly, then come down slowly as it listens for korotkoff sounds
<Greys> prior to higi these machines would go barely above the required pressure, and then drop down to get the measure; minimizing the time it's cut off
<SilverFox> Greys, what is the "required pressure"?
<Greys> the pressure at which the microphone can't hear your pulse anymore
<SilverFox> do you know how much you're supposed to go above that number?
<Greys> no, but I'd guess 30 isn't it
<Greys> probably more like 5~10
<SilverFox> 30 is exactly that number
<Greys> then why did none of them do that before higi?
<SilverFox> the readings these machines are giving are more accurate than the ones before them
<SilverFox> probably because they were shit
<SilverFox> or the assumed normal pressure was lower
<Greys> except they're less accurate because I can feel my bloodpressure after using them and I couldn't before -- and not in my arm
<SilverFox> going 30 above the point of not hearing pulse is the golden standard of doing it, which gives the most accurate reading
<SilverFox> going 5-10 above is shit and will give inaccurate readings
<Greys> I mean, it's a free thing what steals your personal information sat near the pharmacy at the supermarket
<Greys> accuracy isn't on this table
<Greys> fun fact because this is getting boring; the walmart machine does eye exams
<SilverFox> first off, you're wrong, second of all, what personal information is it stealing?
<Greys> as much as possible; that's higi's business
<SilverFox> answer my question, what personal information is it stealing?
<Greys> they want you to sign up, get emails, give them your date of birth, tell you about spending habits, they'll probably take your SSN given the chance
<Greys> it's a whole bullshit media platform, there's probably an app
<Greys> so they can track your physical location
<Greys> the square above the screen is a hole, then there's a mirror, then more hole, and a little screen
<TheKosmonaut> What’s your usual bp?
<Greys> dono, it's been years since I've met a machine worth using
<Greys> not good
<SilverFox> higher than 140/90?
<Greys> I don't think so, but close
<SilverFox> how long ago would that have been?
<TheKosmonaut> My dad had crazy high bp at one point
<Greys> more than a year, less than three
<TheKosmonaut> He said “I thought it was normal that you could feel your pulse and hear it when lying down”
<SilverFox> nope
<TheKosmonaut> All better now tho
<SilverFox> very not normal
<Greys> back to bed, almost time to wake up
