asciilifeform: stirrup finder! aka ninjasp4mz0r
asciilifeform: mr. spam is back!
asciilifeform: cloudflare 'leak' << 'he ran into my knife, by accident, ten times!'
asciilifeform: chumps will buy anything?
asciilifeform: kakobrekla: i own several. who doesn't?
asciilifeform: dignork: no data sheet (at the time) - but leaked fw update util. that chinese scammers used to sell fake (undersized) usb drives at russian flea markets. lifted fw protocol off the wire from these.
asciilifeform: !up topace
asciilifeform: dignork: yes, 8051 variant. yes, ida eats it just fine. but most of the registers are not documented, so much puzzle work.
asciilifeform: now some huckster gets to pretend he had 'glorious original thought.'
asciilifeform: so never published.
asciilifeform: re: usb diddling: i had the entire thing working two years ago, with same 'phison', likewise cribbed russian docs. didn't think it was interesting to anyone other than me. ☟︎
asciilifeform: sold in just about every shop of any description.
asciilifeform: those are so common, every man woman and child in usa can get own pipe right now from existing inventory, most likely.
asciilifeform: lol
asciilifeform: nubbins`: normal people do that with taps
asciilifeform: http://www.sherline.com << vendor
asciilifeform: these are reasonably common.
asciilifeform: some folks do.
asciilifeform once actually filmed indicator lights on refrigerator, using high speed camera (verified they were, indeed, oscillating, because someone should've failed electrical school)
asciilifeform: microwave timer ?
asciilifeform: and, interestingly, made in usa (ancient german patent, i think)
asciilifeform: yes, it's scarcely larger than sewing machine
asciilifeform: yes, that one.
asciilifeform now posted what may be least interesting film on the net
asciilifeform: mircea_popescu: http://www.youtube.com/watch?v=CYC0cT-sYBw
asciilifeform off to bed
asciilifeform: unlike a purely mechanical pick'n'place (these exist), this one will have ability to return to preset coordinates.
asciilifeform: 'waldo' yes.
asciilifeform: (customary in adult production line)
asciilifeform: vs. machine vision
asciilifeform: (coordinates for motion plus manual jogs)
asciilifeform: reel feed is less important when machine is being driven semi-manually
asciilifeform: for very questionable performance.
asciilifeform: yes.
asciilifeform: mine - costs mainly blood.
asciilifeform: decimation: more importantly, is the fact that their machines cost money that i don't have.
asciilifeform: model railroad is not physically much like an actual railroad.
asciilifeform: precisely, as someone mentioned earlier, railroads
asciilifeform is very much familiar with the traditional setup
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.
asciilifeform: 'long ago, in galaxy far away.'
asciilifeform: Vexual: been in factories << as a boy
asciilifeform: masswise: 1%
asciilifeform: (spatial)
asciilifeform: decimation: 0.1mm
asciilifeform: 'how to eat the airplane? one piece at a time.'
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) ☟︎
asciilifeform: i'm genuinely surprised no one wrote in to say 'madness'
asciilifeform: because NRE (nonrecoverable engineering cost) is deadly
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...) ☟︎
asciilifeform: decimation: but very small.
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)
asciilifeform: decimation: i don't have a cnc lathe.
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: not nearly as shiny.
asciilifeform: Vexual: testing that piece presently. there shall be pictures.
asciilifeform: in fact, i didn't invent any of this.
asciilifeform: i did not invent the principle.
asciilifeform: ah yes.
asciilifeform: the luer fits needle, just as it was sold for.
asciilifeform: which 'it'
asciilifeform: thick end - 1/4-32 (american. i didn't make the luer, and no metric luer could be easily sourced.)
asciilifeform: thin end is rotor flange.
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: while retaining vacuum.
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:
asciilifeform: this piece - possibly.
asciilifeform: that leaves (2).
asciilifeform: (1) is not an option given the modest budget.
asciilifeform: 2) machine it.
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
asciilifeform: Vexual: drilled, yes.
asciilifeform: TheNewDeal: i need exactly one.
asciilifeform: TheNewDeal: no, god threw it down to earth just now.
asciilifeform: 'nothing sucks like Electrolux. (tm)'
asciilifeform: Vexual: pick'n'place nozzle.
asciilifeform: ;;later tell mircea_popescu http://imgur.com/a/CmtqQ << blood, sweat, and... brass.
asciilifeform: http://worstcats.tumblr.com << highly relevant
asciilifeform: !s Montrezor
asciilifeform: 'For the love of God, Montrezor!'
asciilifeform: even without enemy. phone rings, draw, put to head - but drew from wrong holster.
asciilifeform not expert in field
asciilifeform: rabbit could shit in your face if you hold it like a bottle and drink?
asciilifeform: (also works for cow, i imagine, but for some reason not popular.)
asciilifeform: or that.
asciilifeform: cazalla: not commercially available off-shelf, sure. but good project for amateur machinist.
asciilifeform: cazalla: machines. see link.
asciilifeform: why waste.
asciilifeform: if mammal - milk it.
asciilifeform: obligatory: https://www.youtube.com/watch?v=mUtSazFb5qM
asciilifeform searched for 'rabbit milking machine' - found: http://elevenredpaperclips.com/wp-content/uploads/2013/01/SAM_0847.jpg
