06:56 PM rue_: hmm $400 50Mhz, dual channel digital scope...
06:56 PM rue_: should I?
07:15 PM Tom_L: you could probably get a 100 for that
07:16 PM Tom_L: i know what you can do with the $400 though
07:19 PM theBear: pfft ! silly digital scopes... if i really wanna count a freq i can count it on my analog scopes nice grid and clear timebase/various-multiplier-options knobs, but on those other 99% of occasions i feel a need to poke something with a scope, i like to see the screen change at least soon-ish after i move the probe... i spose a digital one could be handy in situations where yer can't look while probing, cos it gives you time to turn around and maybe
07:19 PM theBear: get comfy in yer chair before it displays what you just probed <cheeky any-chance-to-abuse-something-that-pissed-me-off-in-the-past grin>
07:21 PM Tom_L: digital you're generally looking at timing of some sort where a logic analyser will do very well
07:24 PM theBear: that too... i gotta admit i am stretching my not-small cro experience when i do things like debug 250kbps LONG "packet" (ya know, header/break signal then ton of payload/data before a gap/footer/break signal style)serial streams, or "watch" a frame of pal/ntsc comp. video squeezed into a single screen on the old 20mhz entry level 2ch thinger i got... surprising how effective it can be with a little practice and more than a little experience
07:24 PM theBear: abusing/forcing the sync section to do what you want.. things like detecting crappy cables/general-low-passed-crap-image or horrible not-focused-ness when you wave a few fingers past a vid cam on the bench...
07:27 PM theBear: fortunately most times fast digital issues i can deal with comfortably in digital (these days micro with fancy mouse+keyboard+multi-window-screen assistance) land without having to touch a probe or iron, and well, video ain't really a big thing for me, more of a hobby/novelty/'fancy switchable/multi-notification-mode door-bell' :-D
07:27 PM theBear: oh, and the very occasional key evidence in an axe-murder trial ... good camera, you sure helping to put that maniac where he can't hurt anyone else, slowly slowly as legal gears seem to turn
07:28 PM theBear: speaking of my camera hobby, here's a link/self-quote i threw a few places i hang around earlier, cos pfft, i took maybe 3 or 5 minutes to put it together, may as well milk it
07:29 PM theBear: here, have a link --> imgur.com/a/ZqjwT mention was made of when a few of us started using motion (motion detection/recordey/awesome-everything but very much not overkill or gui like that other project i forgot the name of (looks like a commercial swann style security cam system/gui)) so i grabbed some of the oldest pics i recently stumbled on that i made with it, and some medium age timelapse (ninja level robot-disco-light repairs) and even a
07:29 PM theBear: not-much-different-to-now bear-head for contrast :-]
07:32 PM theBear: seems the gifv auto-convert (i was more curious what happened if i tried to put a video on imgur than anything, seems it auto-converts to fancy modern-html video :-) stretched it out to about 35mb, but the vid is a little timelapse of a repair i did one day at work, nothing unusual for that job/place, but i feel really high-grade world-class kinda top-of-my-game robot-movey-disco-light-major-ish-repair work, and i'm sure my memory isn't patronising
07:32 PM theBear: me when it says at least a few people who viewed it in the past found it interesting or entertaining in one or more ways
07:46 PM z64555: what the
07:46 PM z64555: oh its just theBear
07:47 PM Tom_L: he's gotta fill the silent gaps
07:47 PM z64555: he does that quite well
07:54 PM theBear: hehe yeah, it's kinda appropriate in here, bit of a quieter channel... on rantey days those poor effers in big channels like ##electronics sure put up with more me than there is gaps, in exchange for only the occasional tidbit or protip of actual helpful answers <grin>
07:57 PM theBear: this time tho, i'm upgrading to <slightly more than mildly disappointed expression> that NOONE has said anything about my cool timelapse of awesome international-competition-grade timelapsed disco-light-repair :-( heck, outta the 1000 odd various names that have potentially received and possibly clicked that link thismorning, i'm kinda surprised i didn't get a single comment re: ear-moustaches, even a negative/opinion==that's_silly kinda one, which
07:57 PM theBear: i kinda expect from someone nearby whenever i mention either the concept or the name i picked for it <grin>
07:57 PM * Tom_L thinks rue_ fell outta his chair
07:57 PM theBear: that's more like it <biggrin>
07:57 PM Tom_L: theBear you're not still doin that stuff are ya?
07:58 PM orlock: theBear: motion is awesome, that big light almost looks like a fork mounted telscope
07:58 PM rue_: I'm back
07:59 PM Tom_L: rue_ did you see the part i cut today?
08:01 PM theBear: oh, notes for the timelapse include "that's a $550aud COST/TRADE price fancy cad-calculated ultimately hi-tech perfectly err, fancy output all glass (maybe deposited allyminimum reflectey surface?) lens i slip into the back there, behind the umm, 700w? mh/hid lamp" erm, "that's a super fancy not-rivet-gun that puts really good threads into any old metal hole you can point it at" (pretty sure that's this vid) erm, "that's the edge of a 40a
08:01 PM theBear: 3phase/415/240vac power socket on the lower left just kinda, on my bench 'cos i do the heavy duty stuff too" and "that single light is worth something ridiculous like just under $20k !"
08:02 PM rue_: theBear, we didn't finish your 3d design tutorial
08:02 PM orlock: theBear: heh same as the telescope parts too then...
08:03 PM orlock: "first surface" mirror
08:04 PM theBear: and nah, things like that (medium/common, but not close to the big+heavy biggest similar and other entertainmentey kinda lights i dealt with) weight maybe 40-60kg, and just to get em outta a roadcase and onto the bench you gotta flip the whole floppy dual-axis-yokey thing upside down using just the two side handles (one visible in video) and well, currently if i working on a plasma tv for a friend who asks REALLY nicely (i like lcds, i'm colourblind
08:04 PM theBear: and they're cheap and not-hot and very civilised voltages all round :-] ) i need an assistant to move/rotate it during the repair.... that's why i'm more into the laptops and mobile phones and random small bits and pieces for friends and associates i feel are worthy to get my heavily subsidized current "rates"
08:04 PM orlock: Forki'n mount
08:07 PM theBear: rue_, it's ture, and believe it or not i have played with at least one of the 2 or 3 thing/app/programs involved in that tutorial since, but it's been a bit all over the place recently... just been away for a week and a bit to see my little bro become Mr little-bro, "by the power vested in me" style and various associated tasks including lots of helping out and generally covering staff-eff-ups for mum while she been away a bit longer than that (she
08:07 PM theBear: owns/runs a little fancy cafe/lunchbar the last few years, but ain't at the stage where she isn't 99% of the management and a decent % of the day to day in-person kinda staffs) and i dunno, it's been a long hot summer, i just been getting nothing done fast, and at levels very few others have achieved <grin>
08:10 PM Tom_L: the elite few?
08:10 PM * Tom_L thinks theBear should have been an author
08:11 PM theBear: orlock, heh, not even close, that's one of the maybe 3 or 4 BIG international name-brands in the modern fancy robot-style-disco-light industry, and being a approved tech/warranty agent and a major partner (entire tech dept for this HUGE state across the country from the importer/distributor/agent, and the company my repair dept was within had literally over a hundred of various similar models, huge contracts etc etc,) i was strictly on a
08:11 PM theBear: proper-spec'd-parts-only, which was fine with things like sunon fans i could import independantly rather than have repackaged in denmark for a +200% markup, but things like those lenses are kinda specific to the units, ya know, gotta fit, not-explode mere inches from a quartz-glass single-layer/capsule hid lamp running just under 1000c outside glass temp (the glass glows more than a little red when the lamp is extinguished/turned off,) and aim the
08:11 PM theBear: light kinda the right way for all the little lenses and colour wheels and bits in front
08:11 PM * Tom_L of the "Mark Twain" style
08:11 PM theBear: Tom_L, i like to think so... now ithat i'm "retired" i don't think "doing nothing fast" is anything i'm supposed to be ashamed of.... kinda par for the course <cheeky grin>
08:16 PM orlock: theBear: You'd like it here i think
08:16 PM orlock: theBear: except for the whole different state and multinational megacorp bit
08:17 PM theBear: orlock, the latest model that company released before i had my first break from fulltime work for spinal kinda reasons, maybe pfft, 6ish years ago, sold for much closer to $30k AUD a unit, and it was infinitely simpler than all previous models... ones like the one in the video, maybe 2005-2008 release/designs, had lots of tiny little super-many-stranded literally nasa-designed spaceship grade cables running all up from the base thru the center of
08:17 PM theBear: the bigger U yoke and up the arms into the top ufo-oblong bit, all the stepper drivers either in the base or the arms (earlier models ALL wires ran right from base thru moving arms to the steppers/lamp/etc/etc), the newer one while slightly larger physically and a few more watts of lamp, was all modern lightweight cheap electronic ballast and integrated hot-restarted instead of big copper and pfc correcting copper and heavy wiring and potted
08:17 PM theBear: lamp-starter units, and had a single CAN bus and all identical driver/stepper modules, so basically a little bit of power and what is can, 3 wires ? running to a bunch of identical cheaply mass produced little stepper-driver boards that were addressed by the socket they were plugged into when placed wherever, basically maybe 10 or 15 avr's and a couple dmx/rs-485 tranceiver ic's, and a couple few-hundred-watt switchers and some lenses and
08:17 PM theBear: steppers... thirty thousand effing dollars !
08:17 PM theBear: orlock, i ain't been a lot of places, but increasingly with age, i find new ones pleasing
08:17 PM orlock: Lotta steppers here.
08:18 PM orlock: Shelves full of them
08:18 PM orlock: we custom design our own stepper drivers too
08:18 PM orlock: on PCI cards, amongst others
08:19 PM orlock: Not so much in the way of high-end optics in the gear at this site however
08:19 PM orlock: which is kind of annoying and dissapointing
08:19 PM theBear: heh, and re: megacorps and such, being gruff old theBear.. always comes with glowing recommendations and known for doing what few other do and doing it well... the more structured and "proper" a business exposed to me for extended periods is, i suspect the more they struggle to adapt to how i conduct myself, rather than the other way (heh, i actually prefer a proper corporate structure, definate rules and hierarchy, no grey areas etc, but just
08:19 PM orlock: theBear: this place makes biotech robots for a globally known optical brand
08:19 PM theBear: because i like it, don't mean it likes me <grin>)
08:20 PM orlock: amongst other things
08:20 PM orlock: prior to a big corporate split a few years ago, we also had as some of our brands Fluke and Tektronix amongst others
08:20 PM orlock: the Stackhat was designed by these guys too
08:20 PM theBear: wtf even IS a biotech robot ? or optical brand while we at it ? oh wait, i ain't a big non-stage-lighting/video-projector kinda optics guy, but i suspect "Karl Zeiss" is a known optical brand, his damned name is on every 2nd lens i see outside of eye-glasses these days :)
08:21 PM orlock: theBear: Leica
08:21 PM orlock: theBear: and its a robot that process human tissue samples, applies very expensive chemicals to them
08:21 PM orlock: to create a histological reaction based on specific cancer types
08:21 PM theBear: ooooh, i on the other hand only been in other peoples workshops where i get to even see tektronix, and my first ever fluke privately or professionally was a gift/multi-favour-repayment, and 2ndhand and far from top or even middle of their now vast range, and only arrived maybe 2 years ago now :)
08:22 PM theBear: oh, does all that painfully repetetive and mindless labwork that they show poor scientists micro-pipetting a little whenever tv news mentions something like cancer or medical-advances ... that's kinda cool
08:22 PM orlock: theBear: Fluke and Tektronix are owned by the same company, and used to be owned by our parent company
08:22 PM orlock: yes, exactly that
08:23 PM orlock: and uses stupidly expensive chemicals that are hard to mae
08:23 PM orlock: not just chemicals
08:23 PM orlock: biologically active reagents
08:23 PM orlock: think printers and ink
08:23 PM orlock: we make the printers
08:23 PM orlock: sister company in the UK makes the ink
08:24 PM theBear: mmm, i'm some years outta date, and farnells reps stopped visiting in person here late-90s, pretty sure that one is more modern business rationalism rather than not liking me, i get the impression industry/tech-associates that get brief bursts of me now and again find it very entertaining, vs the majority of other somewhat less animated persons in the tech kinda world
08:24 PM orlock: these robots are all FDA certified, etc
08:24 PM orlock: we "we including the guys next door" made a 3d printer that printed biologocal tissue about 10 years back as well
08:25 PM orlock: https://www.youtube.com/watch?v=EvS39zq2cT8
08:25 PM orlock: that's filmed downstairs
08:26 PM theBear: mmm, that's all kinda fun sounding... just outta interest, and no need to give away anything that yer sposed to keep a bit unnamed or quiet, but you talking little printers with shootey ink or electrostat-sucked-up toner kinda stuff, or offset huge mass-production things, or screen/poster printers (not really sure what the non-manual modern version of that one is) or what kinda end of that stuff... oooh, you talking fancy 1-extra-D printers and erm,
08:26 PM theBear: non-literal "ink" ... lucky bugger
08:26 PM orlock: makes printer ink look cheap
08:27 PM orlock: <--- just a janitor
08:27 PM * orlock stads up for the first time in 5 hours...
08:29 PM theBear: do me a big favour and turn yer direction towards printing more springy bone-seperating kinda tissues, and erm, magic little i dunno, tubes that somehow can re-join and un-deaden severed nerves... get that going on for me, and heck, i'll come anywhere and do anything you need done for many many years happily.. i'll have medically unwise recreation periods when i'm not working, weekends and such, but if anything that improves my work output on the
08:29 PM theBear: long and medium term, even the short term... damn i miss those silly illegal "discos" i used to frequent so often...
08:30 PM theBear: mmm, if yer print that stuff i just mentioned, i'll even happily janit with you... unfortunately all my life i've found sweeping/mopping actions incredibly painful... stupid defectively-shaped/formed body parts
08:32 PM theBear: or i spose bionic parts would be an acceptable alternative... heck, even that health-insurance ad with the paralympic dude who's got a pair of deformed leaf-spring things instead of feet and shins looks like he's having a ton more fun walking and running than i do with a half dead leg... tho i suspect any doctor will refuse to chop off a basically healthy half a leg and replace it with a big pogo spring, specially the kind that the govt gives for
08:32 PM theBear: free :)
08:34 PM theBear: don't get uneasy, i ain't passive-agressive style wallowing in crippledness here, just ya know, letting my imagination run free fer a short narrative
08:34 PM theBear: seriously tho, those springey not-lower-leg things some of the paralympic sprinter/runner kinda guys got these days look like a LOTTA fun, kinda thing i'd muse about getting fitted even if i had perfectly fit and healthy feet both side
