Vexual: ther's certainly more to that story
BingoBoingo: http://www.thedrinkingrecord.com/2014/10/02/negative-security-your-local-pd-selling-holes-like-a-cheap-pimp/ << Hope this informa

Vexual: https://www.youtube.com/watch?v=6YLaAvXU734 my dog is inside the piano
Vexual: type ab knows what to do next
Vexual: but a drunk alone doesnt get far past the showroom
Vexual: thats my understanding, a humanlike thing approximates the position then uses a camera to fine tune
asciilifeform off to bed
decimation: there was a time when computers were a mechanical affair: http://www.youtube.com/watch?v=i5P5faf7478 << model of "COLOSSUS" running at bletchley park
asciilifeform: unlike a purely mechanical pick'n'place (these exist), this one will have ability to return to preset coordinates.
decimation: ok that makes sense, would be a good compromise for prototyping. it would be damn handy to hit a key to make the thing move 0.1mm instead of trying to finesse it
decimation: yean even the 'cheap' chinese one was like $4k I think
asciilifeform: decimation: more importantly, is the fact that their machines cost money that i don't have.
decimation: I think you will safely beat these guys in quality http://hackaday.com/2014/09/24/pick-and-place-machines-at-maker-faire/
asciilifeform is very much familiar with the traditional setup
Vexual: doesnt hurt to have a look
asciilifeform: Vexual: how all of this is done in 'adult' factory - is very well known. (anyone who gives a damn - find university library.) but won't help here.
Vexual: a week in shenzen might be a goos use of time
Vexual: yeah 20/hr at that
asciilifeform: 'how to eat the airplane? one piece at a time.'
decimation: asciilifeform: what kind of precision are you trying to meet with your paste squirter?
decimation: yeah the smallest smt parts are a bitch
asciilifeform: the pick'n'place cum pastelayer is the only cut to a 'gordian knot' - namely, can't have the boards populated at a genuine factory (prohibitive cost for small batches) - but can't populate by hand with acceptable yield (very fine-pitch components) ☟︎
BingoBoingo: I can only imagine what the pressure is like when the penguin only has a 3-4 hour drive
decimation: it seems to me that the quantity that you are minimizing is your time investment
asciilifeform: i'm genuinely surprised no one wrote in to say 'madness'
decimation: well, the idea is that you are investing in the equipment required to build other products in the future, thus making the NRE "recoverable"
asciilifeform: can't have a part machined, for example, unless there is no possibility of making it to spec with own hands (pcbs with soldermask, vias, hard gold - fall into this category)
asciilifeform: so everything must be done in the most painfully economical way.
asciilifeform: i may have said it before, but i will repeat: s.nsa has a piggy (see mircea_popescu's site); every month, i invoice him for materials, get some btc. but, since i can't safely convert btc to usd where i live, i just sit on them. they will probably be buried with me. hence: s.nsa, presently, in practice runs on guess what (my pocket money...) ☟︎
decimation: I wonder if there is a subtle 'puff' effect from flex tube as the vaccuum is released and the tube rebounds
decimation: I can see how a flex tube that pulls a decent vaccuum would interfere with a x/y positioner's movement
decimation: yeah this is definitely a hardcore solution, probably higher quality than many pro pick'n place machines
asciilifeform: decimation: flexible tube is annoying in various ways (can't rotate 360 deg.; wear around the connector ends; nonlinear resistance to turning, have to use gear train on stepper; etc)
assbot: Making a homemade metal semi-automatic rifle just got crazy easy | Ars Technica
BingoBoingo: asciilifeform: Former plastic pistol dudes may have an offering for the offing... http://arstechnica.com/tech-policy/2014/10/making-a-homemade-metal-semi-automatic-rifle-just-got-crazy-easy/
decimation: asciilifeform: why not use a flexible tube?
asciilifeform: decimation: yes, with that lathe. with what else.
asciilifeform: at any rate, hopefully answered the question of why simple-looking piece of junk had to be laboriously cut.
asciilifeform: luers are 19th c. tech.
asciilifeform: Vexual: testing that piece presently. there shall be pictures.
Vexual: did you solve the glue dilemma?
asciilifeform: in fact, i didn't invent any of this.
asciilifeform: i did not invent the principle.
Vexual: the rotation and the vacuum part
asciilifeform: thick end - 1/4-32 (american. i didn't make the luer, and no metric luer could be easily sourced.)
Vexual: i was wondering whyy that bell end was at the other end
asciilifeform: needed - this size.
asciilifeform: this setup is in fact available off shelf - but in gigantic version (for use with compressed air shop tools)
asciilifeform: pictured item is a rotor. thin end gets ptfe ring (in groove not yet cut in piece shown.) rotates inside, surprise, stator (not shown)
asciilifeform: answer to why above part not available off shelf:
Vexual: woeks in the wet
assbot: Exothermic welding - Wikipedia, the free encyclopedia
decimation: thermite welding was used to weld railroad tracks in jungle conditions http://en.wikipedia.org/wiki/Cadwelding
Vexual: you'll find more danger with the pice getting stuck to the wheel and comin atchya at some aweful rate
BingoBoingo: Vexual: From embedded iron that oxidized in the wheel.
Vexual: wheres all thisoxygen coming from?
BingoBoingo: And the two ingredients have 3 elements between them...
BingoBoingo: Seriously though... All of the fire the thermite references here... Thermite has exactly two ingredients...
TheNewDeal: shiiit I'm gonna use the diamonds in my teeth and cut it like Jaws
BingoBoingo: TheNewDeal: Well, a bandsaw has rather controllable surfaces. A grinding wheel though if you work aluminium... turns into the bane of COmmunity College machine shops
Vexual: expands locally hence the need for parrafin wax lube
TheNewDeal: I'm not saying it isn't possible, but I'm pretty sure I've cut the shit on a band saw, while lightly spraying some lubricant, and had no problems of ignition. That band saw was for sure used in cutting other things (not sure how much iron)
BingoBoingo: Also about things that generate heat... like thermite.
Vexual: i always thought it was more about the heat
BingoBoingo: TheNewDeal: It isn't necessarily that Aluminum is flamable enough on its own. Nearly any grinding equiptment usually put upon it will have already cut iron and have various Iron oxides in it...
BingoBoingo: xanthyos: Is that TradeFartress
BingoBoingo: Aluminium also clogs the shit out of grinding wheels
Vexual: i mean the part he machined, me thinks i could find something in my own junkyard, it must be the way it attaches to the machine or something
TheNewDeal: why do you say that bb?
decimation: asciilifeform: did you make that on your manual lathe http://log.bitcoin-assets.com/?date=08-08-2014#786567 ? ☝︎
BingoBoingo: <asciilifeform> TheNewDeal: harder than Al, not as tricky to machine as stainless steel << To be fair machining Aluminium is plenty tricky on its own
BingoBoingo: asciilifeform: By 2018 Maybe I can commision a euphonium? I don't even want to think about how long a Tuba would take.
decimation: neat-o ascii, congrats on the manufacture
BingoBoingo: Expecting a plastic to survive solder beads?
BingoBoingo: Real lead pencils may be the shit, but...
BingoBoingo: And then you'll need 40 locking apparati minimum
BingoBoingo: Sure, you can claim Diabeetus and get soft plastic shit that wears like hell
BingoBoingo: Vexual: Well, it is hard to get a leuer lock without an expensive ass IV pump or heroin habit
Vexual: what about that thing means it's not available off the shelf?
BingoBoingo: When dealing with brass anything... You have to pretty much machine it yourself
Vexual: drawing one would take as long as making one
asciilifeform: (1) is not an option given the modest budget.
asciilifeform: 1) pay someone to machine it
asciilifeform: (provided that it cannot be had off the shelf)
asciilifeform: there are two basic things one can do when need part of a specific shape and size, and no other.
asciilifeform: TheNewDeal: harder than Al, not as tricky to machine as stainless steel
TheNewDeal: why was brass chosen, if I might continue to pester you with manufacturing questions?
Vexual: is it straight thru inside? the outside is a piece of art
TheNewDeal: are they expensive to procure and you have muchos tiempos on your manos?
asciilifeform: TheNewDeal: no, god threw it down to earth just now.
asciilifeform: ;;later tell mircea_popescu http://imgur.com/a/CmtqQ << blood, sweat, and... brass.
danielpbarron: yeah, but he also paid to have it advertised on Free Talk Live to a slightly bigger retard following
danielpbarron: TheNewDeal, no problem unless you are one of the many who probably bought it because MWD hyped it up
danielpbarron: http://freedomfeens.bit/ is probably a thing
TheNewDeal: whats the problem with namecoin price decreasing anyways?
danielpbarron: i used to have a bunch of names
Vexual: danielpbarron: can you think of a dotbit site off the top of your head?
