Back
[00:11:05] <z64555> hm, well, it's more of a corkboard than a chalk board
[00:11:39] <z64555> where you can stick items on index cards and then pin them up in columns
[00:12:43] <z64555> it's just missing the string, and it'll be a complete forensic board
[00:19:30] <Jak_o_Shadows> xfce4-terminal is crazy.
[00:19:41] <Jak_o_Shadows> It pops up a separate window for ssh password/connections
[01:27:52] <Jak_o_Shadows> USB hat switches are full of crazy. There's 4 cardinal directions, in 4 bits. But hey, let's not store them as the 4 bits. Let's number the bits, and make the numbers correspond to angles
[02:28:12] <rue_shop3> hmm
[02:36:59] <theBear> we talking like mini-joystick "hat", or something for my head to wear in the sun ?
[02:43:30] <Jak_o_Shadows> mini-joystick hat
[02:43:41] <Jak_o_Shadows> Through, if you have a usb powered hat, i'm not judging you
[02:53:12] <theBear> hehe, i wouldn't blame yer if yer did, but i can honestly, perhaps even proudly, declare that none of my hats have ANY usb related options
[02:55:59] <Jak_o_Shadows> aha
[02:58:11] <rue_shop3> hmm
[02:58:53] <rue_shop3> I wonder if I can servo control a dc motor enough to substitute a stepper
[03:00:16] <Jak_o_Shadows> I think the only tricky bit in there is "if I can". Also what motor you use, and the position feedback you have
[03:02:56] <rue_shop3> I'm going for 16 error counts
[03:05:55] <theBear> rue_shop3, context i missed re: stepper/dc application ?
[03:17:46] <rue_shop3> oh I'm trying to get another cnc machine made
[03:17:58] <rue_shop3> the steppers I have prolly aren't big enough
[03:22:37] <theBear> hmmmmm, you got any feedback/closed-loop involved ?
[03:22:49] <rue_shop3> yup
[03:23:06] <theBear> in that case eff steppers, dc forever <grin>
[03:23:14] <rue_shop3> most of what I'm working on now is making the project so complex I dont get it working in the irst place
[03:23:30] <rue_shop3> first
[03:23:40] <rue_shop3> haha even with a modem M keyboard I cant type anymore
[03:25:06] <theBear> way i been thinking last few years re: diy cnc kinda stuffs is that if you got feedback, dc, likely with a little higher gearing than stepper woulda been, make a lot more sense ... with stepper you limited to a step'th of min res, obviously gearing is possible, but you still got the step'th absolute, but with dc and good feedback, resolution comes down to backlash or in a perfect world, res of your feedback
[03:25:16] <theBear> lol
[03:25:37] <rue_shop3> I worked out a design that might work out
[03:26:03] <rue_shop3> 18thread/inch rod, with a 10:1 reduction to a motor that can top out 3600 rpm
[03:26:28] <theBear> heh, is that "most of what I'm working on now is making the project so complex I dont get it working in the irst place" a statement of observed fact, or more of a plan for err, ya know, that word that means professional-lazy
[03:26:44] <rue_shop3> with a encoder I can get 90 pulses/rev from, I should get 1/2000" with 16 counts for error
[03:27:35] <theBear> hmmmm... calculator says .05, but i not sure i made the math the right way round, or even if i did what units that would be <grin>
[03:27:43] <theBear> oh, .05 minutes an inch maybe ?
[03:27:54] <rue_shop3> Tom_L, I still have those geared encoder motors we all bought
[03:28:11] <theBear> hmm, you said "counts for error" twice now, making me think i should ask what exactly that means
[03:28:13] <rue_shop3> 0.5 thousands of an inch
[03:28:27] <rue_shop3> well, the encoder cant just change on the mark you need to hit
[03:28:41] <rue_shop3> you need to know when your comming up on it, and how much you passed it
[03:28:49] <rue_shop3> I made this mistake before
[03:29:01] <theBear> you mean my .05 ? it was sposed to be how long it takes your previous numbers to move an inch, purely for idle curiosity, so i don't think it can be in units of length <grin>
[03:29:17] <rue_shop3> you need to have a few lines to say your in need of pushing harder to correct the posision
[03:29:28] <rue_shop3> .0005 inches
[03:29:54] <theBear> oh, you saying your ACTUAL encoder res would be 1/2000" * 16 but you confident you can beat that thru programming-tech ?
[03:29:58] <rue_shop3> so I'm using 16ish
[03:30:03] <rue_shop3> yea
[03:30:17] <rue_shop3> its got +-8 lines to ramp power up and down
[03:30:22] <rue_shop3> which is tight, but I think doable
[03:30:31] <theBear> cool, now i can comprehend any further stuff i likely can't help with <grin>
[03:31:07] * rue_shop3 digs thru box
[03:31:34] * theBear digs disco basslines
[03:31:35] <rue_shop3> ooo I forgot about this one, I was at a surplus bin, they had a dc motor with encoder thrown in the stepper motors box :)
[03:31:38] <rue_shop3> for CHEAP
[03:31:54] <rue_shop3> someone was taught to count wires :)
[03:33:19] <rue_shop3> I have 12 of the HP motors with encoders on the back
[03:33:27] <rue_shop3> from the early inkjet printers
[03:33:50] <rue_shop3> turns out the resolution of the linear ones suck
[03:35:35] <theBear> ooh, you'd be the kinda guy that knows the VERY beginner basics of panelbeating (DO's and DON'T's kinda stuffs...) i know i not allowed to bang away with a hammer or similar like you think as a kid, and that levering off a tyre/wheel or whatever is good, but can i do something like use firm push/weight behind my chosen lump of compatibly shaped wood/crap, for example to pop/inside-out where there a sharpish ding, or is that somehow a no-no ?
[03:36:50] <theBear> by linear there you mean the cheap-plastic-version-of-glass-"ruler" (glass ruler = proper EXPENSIVE thingy that you see on REAL machines) that a lot of inkjets seem to use ?
[03:37:10] <rue_shop3> yea
[03:37:32] <rue_shop3> if you use them for positioning, your resolution sucks by the time you have even 4 counts for error
[03:37:46] <rue_shop3> in those printers, they are almost more of a velocity ref than a positioning signal
[03:38:14] <rue_shop3> the pixel clock would be pll multiplied from that strip
[03:38:30] <rue_shop3> so each line on those is prolly 4 or 8 pixels
[03:42:07] <rue_shop3> well I have 5 encoder-motors that could be suitable
[03:42:12] <rue_shop3> bigger would be nice
[03:45:06] <theBear> so panelbeaeting, can i "push firmly" or is that as forbidden as using a ball pein to make a pebble-beach effect where you didn't want one ?
[03:47:24] <rue_shop3> hah
[03:47:24] <rue_shop3> I'
[03:47:27] <rue_shop3> I'll be
[03:47:51] <rue_shop3> one of these motors is 19:1 with a 100ppr enocder, and at 24V outputs 360rpm
[03:48:05] <rue_shop3> which is dead on spec (in the ways that matter) for my design
[03:48:38] <rue_shop3> huh
[03:50:00] <rue_shop3> its like fate is saying "you cant not try to make this project"
[03:50:37] <rue_shop3> if my other 100ppr encoder (which is new) just happened to turn up, then I'd prettymuch be set
[03:55:17] <theBear> pfft, people like us are special, fate has no say ! we done enough and seen enough that at least in THIS area, we tell fate what gonna happen <grin>
[04:01:41] <rue_shop3> imagine how different the world around you would be if fate weren't beating you back with a baseball bat
[04:02:06] <rue_shop3> its had a time holding you back
[04:02:36] <rue_shop3> thebear dont heel!
[04:04:30] <theBear> i don't heel, i'm a bear, not a dog
[04:05:15] <theBear> lol, you can't feel like that, my most recent major-fate was literally beating me back with the back of a small axe, in the face ! you got it easy maaaaan
[04:05:54] <rue_shop3> yea I'm really worried about whats gonna get thrown at me
[04:06:22] <theBear> wear a hockey mask then, you got them up there :)
[04:06:58] <rue_shop3> global warming, more and more baseball
[04:10:59] <theBear> umm, catcher mask then ?
[04:11:36] <theBear> they got the comfy chin-thinger too, all padded
[04:12:48] <rue_shop3> my goggles have 1/4" thick lexan lenses
[04:13:19] <rue_shop3> the rest of my face may not survive, but I should come out able to see
[04:14:31] <rue_shop3> ok if I want the cnc machine to cut a hexagonal hole in the middle of this plastic gear, how do I align it...
[04:15:38] <rue_shop3> dont want to print the gear
[04:16:21] <rue_shop3> tho
[04:16:37] <rue_shop3> the first rev of these projects never works, so it really dosn't matter what i make it of
[04:16:48] <rue_shop3> its just a stepping stone to the solution that'll work
[04:17:33] <rue_shop3> AND I can cheat
[04:17:39] <rue_shop3> I dont want the GEAR to be printed
[04:18:02] <rue_shop3> but what I need is a hex hole in the gear, and it dosn't matter what the hole is made of
[04:18:28] <rue_shop3> SO, I can cut a round hole in the gear on the lathe, and adapt it with a printed collar
[04:18:50] <rue_shop3> dear god, its 2am
[04:19:21] <rue_shop3> dear god, please dial it back to about 6pm for me, much appreciative, thanks, p.s. sorry for not believing in you.
[04:19:32] <rue_shop3> :)
[04:24:54] <rue_shop3> arg, I'm yawning,
[04:24:56] <rue_shop3> oh right, 2am
[04:26:47] <rue_shop3> objects may appear upside down, this is an illusion, the object is not whats upside down
[04:30:23] <rue_shop3> ok, while its printing that...
[04:30:37] <rue_shop3> I'll redesign it, so that when its finished, I can start the next one
[04:31:07] <rue_shop3> then, while the second one is printing, I'll discover things about the first one I need to correct to make a third one
[04:31:22] <rue_shop3> and, if the third one prints properly, I'll be done
[04:38:07] <rue_shop3> it now occurs to me that, the same technique would work with the cnc if I didn't want the inner bit printed at all
[04:38:24] <rue_shop3> it might be a good idea, pla is kinda brittle
[04:38:40] <theBear> rue_shop3, hey, must be your lucky day, i just checked the magic-techery-clock, and it IS just after 6pm !
[04:38:52] <rue_shop3> hehe
[04:39:08] <rue_shop3> says 2:09:51am here
[04:39:33] <rue_shop3> 1 second is such a damn long time
[04:40:25] <Jak_o_Shadows> rue, I have confidence you can do this
[04:40:37] <rue_shop3> turn back time, well thanks, but...
[04:40:57] <Jak_o_Shadows> theBear, my brother once hit himself in the leg with a blockaxe. Which I bring up approximatley yearly.
[04:41:22] <rue_shop3> ok, I'm printing the hex adapter, and I have a thrust ball retainer lined up for next (as i'm too lazy to spark up another printer just now)
[04:41:59] <rue_shop3> Jak_o_Shadows, I tell people in my shop to not cut towards themselvs and to not hammer towards their crotch...
[04:42:06] <rue_shop3> however...
[04:42:15] <rue_shop3> every so often...
[04:42:24] <rue_shop3> http://ruemohr.org/~ircjunk/not_public_dont_open/besafe.jpg
[04:42:33] <rue_shop3> someone finds something new to add to the list
[04:42:41] <theBear> Jak_o_Shadows, fairy nuff, the umm, i'm guessing you mean with a little speed, and err, not the blunt side, otherwise i'd recommend finding a more interesting story if you gonna repeat it even annually :)
[04:43:07] <theBear> hehe, nice pic
[04:43:21] <rue_shop3> "dude, stop..." :)
[04:43:37] <rue_shop3> just cant stress safety enough I suppose...
[04:44:56] <rue_shop3> atleast he has eye protection on...
[04:46:00] <rue_shop3> ok, I need to drill out this gear... assuming its the one I'm gonna use
[04:46:32] <theBear> rue_shop3, at least his fingers are resting outside the trigger loopey thing, and not right on it <grin>
[04:46:43] <Jak_o_Shadows> theBear, nah, blunt and slow. It's just that it's such a dumb thing to do.
[04:46:53] <rue_shop3> I should print two of those retainers, then I can ditch twice the plastic when they are wrong
[04:47:06] <rue_shop3> theBear, :)
[04:47:39] <Jak_o_Shadows> rue, in a build challenge thing, I once told some of the junior people to be safe. They had a wood saw, and had their underarm under the wood, under where they were sawing. Would've messed up their arm quite badly if they sawed through.
[04:48:03] <theBear> Jak_o_Shadows, heh, when you add that statement, yeah, i can see why you repeat it <grin> it's ok, my brother has done some things that make me worry what might be inside the deep recesses of my own mind
[04:48:11] <Jak_o_Shadows> Then I also told people off for standing in front of air cannons as they pumped it up - ok, it only would've been a broken nose, but the occ health and safety people where already pissed at us
[04:48:39] <theBear> then again, i done some pretty impressively special stuff here and there, just well, at least a little less "obvious" than "avoid hitting self with axe/blockey-blunt-axe"
[04:49:13] <theBear> Jak_o_Shadows, oooh, that'd be a funny one, ya know, from a watching the idiot fail pov
[04:49:24] <rue_shop3> theBear, what if, instead of going somewhere for a holiday, I brought someone to me
[04:52:32] <theBear> rue_shop3, heh, it's a valid use of ones holiday time, i "wonder" tho, if you chose me to answer this query, because those cogs and wheels and what-not in your crafty little mindtank, and in the early stages of forming a CUNNING PLAN, sir :)
[04:55:21] <rue_shop3> for next year I'm looking at going to shenghenti china
[04:55:32] <rue_shop3> where all the part supermarkets are
[04:55:51] <rue_shop3> I think traveling is scarry, but I think that would be fun
[04:55:57] <rue_shop3> I'll see
[04:56:33] <rue_shop3> do you think you would take up on a trip to lame ole canada for a month?
[04:57:00] <rue_shop3> gear drilled, WAITING FOR PRINT
[04:57:31] <theBear> you came to the deadliest big-ass country there is years ago, 'sif you ain't got the 'minerals' ya need to go to some place full of buildings and RELATIVELY 100%-non-alcahol-drinking asian persons <wink>
[04:58:05] <rue_shop3> hmmm
[04:58:24] <rue_shop3> I only really eat rice anyhow
[04:58:41] * rue_shop3 tries to remmeber if he left the machine going again
[04:59:26] <rue_shop3> theBear, that leech got me good tho
[04:59:46] <rue_shop3> man did riff have a laugh watching me try to pull that thing off
[05:00:40] <theBear> do you guys not have leeches ? movies made me think that they more common south of you than anywhere here
[05:00:47] <rue_shop3> I think the best laugh was us trying to adjust to each others accents tho
[05:01:10] <theBear> and course he did, anyone would
[05:01:15] <rue_shop3> _I_ understood leaches to be water creatures, the one that got me WAS IN THE LAWN
[05:02:07] <theBear> damn, that's umm, rare? i mean, your understanding IS right, it's kinda like raining-frogs tho, occasionally something less-than-common can go on in nature
[05:03:00] <rue_shop3> awn leech
[05:03:28] <rue_shop3> amazing
[05:03:35] <rue_shop3> this printed adapter,
[05:03:44] <rue_shop3> the inside is too small, AND the outside is too big
[05:05:48] <rue_shop3> ah, there, outside IS ok
[05:07:15] <theBear> lawn leech ? you shitting me, surely that is only a thing country guys that live in sheds tell foreigners to scare them ?
[05:07:50] <rue_shop3> no, I crossed Riffs lawn in flipflops and came out on the other side with a leech on my toe
[05:08:05] <rue_shop3> AUSTRALIA IS DANGEROUS MAN!
[05:08:18] <rue_shop3> ;)
[05:08:44] <theBear> i know, but i'm just confirming there ain't some special leeches that don't need water and live in lawns, ya know, that even i never heard about :)
[05:13:23] <rue_shop3> I seem to ahve fallen into a 3:30am-11:30am sleeping schedule
[05:14:39] <rue_shop3> cnc machnie, you put a nut on the carrige and turn the threaded rod, right?
[05:14:56] <rue_shop3> I'm working on a different method I'v not been able to build yet,
[05:15:05] <rue_shop3> you fix the threaded rod, and spin the nut
[05:15:25] <rue_shop3> I think the 3d printer is the key to pulling it offf
[05:16:52] <theBear> heh, if not essential, i bet it make it a TON easier...
[05:17:30] <rue_shop3> yea
[05:17:42] <rue_shop3> you can use a much heavier threaded rod, it dosn't need to spin
[05:17:54] <rue_shop3> and it wont flop, so there isn't an rpm limit
[05:18:11] <rue_shop3> less mass for the motor to spin
[05:18:40] <rue_shop3> your set if you can do direct drive with a motor thats got a hollow shaft
[05:18:43] <rue_shop3> (theaded)
[05:18:49] <Jak_o_Shadows> Rif was in queensland yeah? Yeah, screw queensland. Too hollow
[05:18:54] <Jak_o_Shadows> humid*
[05:19:06] <rue_shop3> no, new south wales
[05:19:13] <rue_shop3> coffs harbour
[05:19:17] <theBear> either side of the north border of qld depending what year it been i think, or maybe always south of
[05:19:28] <theBear> rue would know, i only met them at the city end of the holiday
[05:19:32] <rue_shop3> well he moved
[05:19:37] <Jak_o_Shadows> Oh. Well. Screw NSW for reasons
[05:19:46] <rue_shop3> and his daughter was up in the edge of queensland
[05:20:01] <theBear> yeah, i know the reasons, that's why i west-side these days
[05:20:13] <rue_shop3> I do not understand aus. biases
[05:20:53] <Jak_o_Shadows> Everybody dislikes Victorians and NSW because people from the two main cities are a bit arrogant (in general).
[05:21:07] <Jak_o_Shadows> We dislike queensland because humid and *shudder* politics
[05:21:19] <Jak_o_Shadows> Western Australia is nice, except it's bloody far away
[05:21:29] <Jak_o_Shadows> Tasmania the joke is that their slightly inbred.
[05:21:38] <rue_shop3> oh so its like the french in quebec
[05:22:29] <rue_shop3> maybe I should fire up the other printer
[05:22:46] <rue_shop3> arkg, these are only 59%
[05:25:18] <rue_shop3> if I had a whole shelf of these things, I'd prolly have them all going at once at some point
[05:25:43] <Tom_L> and at some point they'd all go bonkers at once on ya
[05:26:18] <Jak_o_Shadows> I'm picturing the thin table with metronomes, how they all sync up
[05:27:04] * rue_shop3 and a fellow were thinking about how many printers a person gets going before one is dedicated to repair parts
[05:28:01] <theBear> between 0 + 1
[05:28:35] <rue_shop3> na, we got 3 here now and only have to make a repair part about every 2 mo
[05:28:53] <rue_shop3> different designs tho
[05:29:26] <Tom_L> which one works best?
[05:29:30] <theBear> rue_shop3, more like the country-n00fies
[05:29:59] <theBear> i wasn't payin attention, i was thinking traditional paper printers :)
[05:30:51] <rue_shop3> oh
[05:31:03] <rue_shop3> there are 3 printers in the shop now
[05:31:11] <rue_shop3> +1 unassembled in a box
[05:32:35] <theBear> i think i got down to only an inkjet and a laserjet(tm) in the kitchen, and one laser noname in the lounge now <grin>
[05:34:07] <rue_shop3> were waiting for HP to come out with a 'ThingJet'
[05:34:57] <Snert> I hate stinkjets
[05:35:53] <Snert> a toner cartridge or bust!
[05:35:55] <rue_shop3> in comparison to printers, 3d printing is still at the impact stage
[05:36:49] <Snert> there's so much more going on with a 3d printer.
[05:37:15] <Snert> hard to compare. The software is where improvements could occur.
[05:37:28] <rue_shop3> in comparison to computers, 3d printing is pre- apple IIe days
[05:42:01] <theBear> Snert, mmm, anyone with a remotely working brain notices pretty quick that aside from any quality or practicality issues with what they spit out, that unless they get fairly regular use they jam up and need new catridges (which fix these issues USUALLY,) more often than they print anything you actually need printed, but seems the average man in the street ain't got such a brain
[05:43:18] <Snert> I tossed my stinkjet a decade ago.
[05:43:27] <Snert> no. 2 decades ago.
[05:43:47] <Snert> first time that my print ran in the rain I tossed it.
[05:45:22] <rue_shop3> I LOVE THIS DESIGN
[05:45:36] <rue_shop3> bearing races work great, after a lot of hand work
[05:46:38] <orlock> How do you tell which bearing wins?
[05:46:45] <orlock> They all look the same to me?
[05:47:13] <rue_shop3> the one in front, duh
[05:48:32] <rue_shop3> front of the circle, dont make me point
[05:50:01] <theBear> heh, i ain't had my own printer for actual printing uses since the star nx1000c i think, which if yer not from the past, was a colour version of a VERY popular ancient dot matrix model :)
[05:50:33] <rue_shop3> colour?!
[05:50:43] <rue_shop3> on a dot matrix? black /red?
[05:51:21] <orlock> nah they could do rgb i thought?
[05:51:27] <rue_shop3> this design is great, but I cant just take a pic, to show the glory its got to be taken apart
[05:51:36] <orlock> i just threw out a laserjet 4050(i think)
[05:51:53] <orlock> i've got an Epson? maybe dot matrix in the shed
[05:52:00] <orlock> new old stock, never used
[05:52:07] <orlock> in box, etc
[05:52:32] <orlock> goddamn aircon lost its gas
[05:52:38] <rue_shop3> carbon paper copy is SO much faster than a laser for doing recipts
[05:53:01] <orlock> It's almost 10:30pm
[05:53:06] <orlock> its 30c
[05:53:10] <orlock> 45% humidity
[05:53:21] <orlock> thank fuck its not as hot as it was earlier
[05:53:29] <theBear> i think it was colour, c'mon man, it was over 20 years ago, i mightbe wrong
[05:53:44] <orlock> there were def. colour dot matrix
[05:54:09] <theBear> http://www.atarimagazines.com/v7n10/nx1000rainbow.html also holy crap ! someone local still lists ribbon-whatchacallems for sale for it

[05:54:28] <theBear> if ya not in the mood to open a link, i quote "First affordable COLOR dot-matrix printer."
[05:54:53] <theBear> wowee ! i don't remember pretty bright ribbons like that one
[05:56:35] <theBear> i notice regularly in more recent times, the ONLY office/pos that aren't "constantly" effing about with an unreliable printer, are the ones with dot matrix somethings, and more than occasionally what i'm pretty darned sure are old ones that just been sitting there buzzing away contentedly since whenever such things were commonly available:)
[05:56:39] <rue_shop3> fractint, huh
[05:57:43] <theBear> wowee.. "completely Epson JX-80 compat" ... that almost-wakes the ghosts of some ancient memories
[05:57:48] <rue_shop3> haha, waste of plastic, the other printer prints a differnt trace size, so its part is completely out
[06:03:07] <rue_shop3> its 3:30am, I'm going to bed
[06:03:12] <rue_shop3> after posting images of this
[06:08:49] <rue_house> http://ruemohr.org/~ircjunk/images/lindrive1.jpg
[06:08:57] <rue_house> http://ruemohr.org/~ircjunk/images/lindrive2.jpg
[06:09:10] <rue_house> the outter washers are part of the main drive block
[06:09:29] <rue_house> the threaded rod is bolted tight at each end
[06:09:41] <rue_house> the two nuts are spun by the gear
[06:09:50] <rue_house> with play between them that takes up the lash
[06:10:13] <rue_house> I had to make that to know how to shape the main block
[06:16:50] <rue_house> ?
[06:16:58] <theBear> sounds likely to me
[06:17:00] <rue_house> can anyone understand me?
[06:17:08] <theBear> what does the gear "grab ?
[06:17:14] <theBear> err "grab"
[06:17:37] <theBear> ya know, catch on, and why doesn't the orangey thing have teeth ?
[06:17:38] <rue_house> the two nuts by a hex collar
[06:17:51] <rue_house> its just an insert to the gear
[06:18:04] <theBear> ooh hex collar eh ? class-ey !
[06:18:27] <rue_house> ther will be a body around it all that compresses the lot
[06:18:40] <rue_house> then i JUST HAVE TO WORK OUT HOW TO DRIVE THE GEAR
[06:18:43] <theBear> yeah, i approve, apart from the hex/tooth-attachment details, it looks much like i imagined
[06:18:47] <rue_house> . stupid caps
[06:19:28] <rue_house> the hex collar will be gued to the nut
[06:19:32] <rue_house> llll
[06:19:35] <theBear> the hex thingy i suspect gives you a good place to eliminate/pre-load-ish fix any backlash inherant to the thread of the nuts/rod
[06:19:39] <theBear> which is nice
[06:19:53] <rue_house> which is why its two nuts and not just one link nut
[06:20:31] <rue_house> withe the two nuts, the whole lot can be compressed to load the thrust bearings and push out the nut lash
[06:20:33] <theBear> ya know, pull/push the bolts from each other to effectively narrow the V channel within them (in reality by "using" one side of the channel on each nut as a virtual skinny single channel)
[06:20:44] <rue_house> the two nuts dont tough
[06:20:46] <theBear> hehe, that sentence was full of dirty words <grin>
[06:20:48] <rue_house> thouch
[06:21:07] <rue_house> if they touched it they would be gay, cant have that
[06:21:17] <theBear> mmm, incomprehensible nonsense similar to several likely words indeed
[06:21:25] <theBear> and hehe <childish giggle> that's what i heard too
[06:21:41] <rue_house> :) I better go to sleep
[06:22:09] <rue_house> I have a drawing, but it looks like a lot of perpendicular lines
[06:23:13] <rue_house> http://ruemohr.org/~ircjunk/images/lindrive1.jpg
[06:23:19] <rue_house> tahts the order of the assembly tho
[06:23:53] <theBear> lol, i think that's kinda what most tech drawings are, isn't it ? at least for us non-artist types
[06:23:55] <rue_house> the new hex bit has two nipples that fit into the gear to help before I glue it
[06:24:04] <rue_house> ok, I'm going to bed, gnight
[06:24:43] <rue_bed> I repeatedly forget about this laptop
[06:26:21] <theBear> lol, i hope you at least padded it so it doesn't hurt when you in-turn remember each night
[06:26:50] <rue_bed> I made the bed about 60cm long
[06:27:22] <rue_bed> I can lie on a pillow and type till I fall asleep
[06:27:27] <theBear> like that fate thing earlier, we're old and cool enough to be allowed some fickle, and i figure that kinda not-solving-the-right-problem stuff (like padding something for comfort, vs not leaving it where we sleep) has been earned, at least in a couple places
[06:27:51] <rue_bed> sure,
[06:27:53] <theBear> lol, i woulda thought you'd want it about 3 or 4 feet longer than that <grin>
[06:28:17] <rue_bed> I'v not yet fallen asleep coding
[06:28:32] <rue_bed> my brain stops
[06:28:34] <theBear> rue_bed, loosely related from my personal archives/workbench
http://testing.fucking.rememberit.com.au/pics/LCD%20bits/IMAG0331.jpg
[06:28:40] <rue_bed> I just kinda stare at the screen
[06:29:17] <rue_bed> hehehe
[06:29:35] <theBear> also note the awesome re-use of a ram-stick salvaged tinyprom (programmed via my vga to 4 soldered wires quick-to-build programmer) and my surprisingly technically-sound handmade (80conductor ide ribbon) lvds pairs :)
[06:30:31] <theBear> hehe, that wacky laptop-screen franken-fit was really high level butchery... gotta know a LOTTA rules to get away with breaking as many as that project did
[06:31:01] <rue_bed> its kinda blurry, coool
[06:31:30] <rue_bed> what was the project?
[06:33:11] <rue_bed> and what did you use for software to program the eeprom
[06:33:27] <rue_bed> the kernel i2c calls?
[06:33:27] <theBear> retrofit a 15" 3:4 shaped lappy screen to a half-smashed netbook for a good buddy.... good enough buddy to talk me into it, but there is no reason good enough to justify/make-sensible the realities of such a project...
[06:33:30] <rue_bed> eep24c?
[06:33:47] <rue_bed> wow
[06:33:56] <theBear> nah, i2cget/put or something, the generic linux-supplied ones
[06:34:00] <rue_bed> how long working the pinout take?
[06:36:49] <theBear> pfft, that's a diddle, even when yer don't have datasheets, which i pretty sure i did (any remotely modern, like lvds interface era lcd they ain't hard to find in webland like they used to be,) a retrofit is easy, worst you gonna have is the 4 pairs outta order.... but dismantling and rebuilding those effing indestructium material lappy hinges was a LOT more work than i predicted, and of course i ccouldn't help having to get the intel dev tools and
[06:36:49] <theBear> rejigging the err, i think some little firmware-area on the gpu side of thigns, maybe the effing bios module, something in that end of town so that the few seconds of post-screen pre-windows was "right"
[09:40:19] <theBear> forget what one could do without outside influences to slow one down.... imagine what theBear could do if he didn't spend so much time trying to find where he put his lighter down !
[09:50:44] * z64555 makes note to send in a robot to periodically hide theBear's lighter
[09:54:06] <theBear> i'm scary-good at it, surely we don't yet have the technology to do anything other than make it easier to find <wink>
[13:23:59] <tsglove> Are there any sub-500$ 3d slam sensors?
[13:24:31] <SpeedEvil> slam?
[13:24:33] <tsglove> I have seen some diy units, yet wondering if there are any that I am missing. I saw a nice one in youtube which was uploaded this past-November2016
[13:25:02] <tsglove> SpeedEvil, hello! Yes, like to create a 3D point-cloud map
[13:25:16] <SpeedEvil> webcam + optical flow
[13:25:55] <tsglove> optical flow... checking that out now!
[13:26:54] <z64555> yeah, a SLAM sensor could be just about anything. SLAM is the algorithm
[13:27:00] <z64555> and
[13:27:04] * z64555 checks his reading
[13:27:06] <tsglove> SpeedEvil, is there a library?
[13:27:11] <tsglove> ahh ok I see the terminology now
[13:27:12] <tsglove> ok
[13:27:14] <z64555> is usually an array of different sensors
[13:27:48] <z64555> Ok, so 3D point-cloud map. You're thinking of a LIDAR and similar
[13:28:28] <z64555> can also use a binocular camera setup, or even a scanning SONAR array
[13:29:17] * z64555 wonders why he capitalised sonar
[13:29:37] <z64555> and I don't think there's a low-powered radar array made just yet
[13:31:01] <z64555> You can use an Xbox kinect in place of a lidar, there's libraries out there that can interface with it. There's some open source projects that use it
[13:31:46] <tsglove> checking those out now
[13:31:51] <tsglove> kinect... hadn´t thought about it!
[13:32:48] <z64555> yeah, it's a low resolution lidar and camera sensor package
[13:49:04] <zhanx> heck I just used sonar last time
[14:03:12] <tsglove> SpeedEvil, the optical flow you mentioned, is the OpenCV component?
[14:52:23] <SpeedEvil> No, I mean the general technique.
[15:43:24] <rue_bed> what happened to good ole webcam based slam?
[16:10:08] <veverak> hmm
[16:10:20] <veverak> most effective way to lift leg (with same servos)
[16:10:23] <veverak> that has 2 axis
[16:10:44] <veverak> (just lift above certain treshold, like 3mm up, x/y is not relevant)
[16:10:54] <veverak> is to move them by same angle until z>=3 ?
[16:12:43] <deshipu> "effective" in what sense?
[16:12:55] <deshipu> fastest? strongest? energy efficient?
[16:13:14] <veverak> energy
[16:13:57] <deshipu> that probably would be only moving one of the servos
[16:14:15] <deshipu> this way you don't incur the penalties for the second one's inefficiencies
[16:14:48] <deshipu> otherwise it's pretty much the same
[16:15:21] <deshipu> oh, an of course move the outermost one, as it has less weight on it
[16:17:28] <veverak> hmm
[16:17:30] <veverak> ok ok
[16:18:40] <deshipu> moving both would get you the best speed
[16:19:39] * veverak won't be moving one anyway
[16:19:45] <veverak> more or less counterintuitive to the system
[16:20:04] <veverak> basic approach is still inverse kinematics
[16:20:27] <veverak> it's more like "in case we can choose, pick something that should be most effective for the servos, given that we know how leg looks"
[16:21:05] <veverak> and given that I move only lineary with IK, it will result in all servos being used anyway
[16:26:25] <rue_house> https://github.com/vatsan/slam
[16:26:25] <rue_house> ?
[16:27:39] <rue_house> how about this, balance the leg so it naturally comes up, then when you want to lift it, just turnteh servo off
[16:28:10] <rue_house> most effective way to >[LIFT]< leg (with same servos)
[16:28:27] <rue_house> its about how the problem is defined you see
[16:28:32] <veverak> :)))
[16:29:15] <rue_house> balance / springs
[17:34:45] <z64555> Don't want too strong of a spring, just enough to bring the foot up
[17:39:52] * rue_house dodges a robot leg flying across the room...
[18:21:17] <Casper> Hi there, maybe someone here knows? I'm searching for some vibration isolation mount thing.. for my heatpump... Does anyone know where to buy some and how to select a proper one?
[18:37:15] <Snert_> got a pic of mounting requirements?
[18:42:28] <Casper> somewhere
[18:43:02] <Casper> ... if imgur want to cooperate
[18:43:49] <Casper> ...
[18:45:07] <Casper> plan c...
[18:45:41] <Casper> https://www.flickr.com/photos/93694432@N04/31909940066/in/dateposted/
[18:47:20] <Snert_> I can't picture how it mounts and what everything looks like. No context.
[18:47:47] <Snert_> so maybe someone else has seen it before.
[18:48:18] <Casper> between the leg and the support
[18:48:50] <Casper> bbl, time to go to homedepot and see what's there
[18:51:00] <z64555> looks like maybe a thick foam washer
[20:15:17] * z64555 reads about robots
[20:23:58] <Snert> I wonder if future humanoid robots will pick up a book about humans and read it.
[20:24:50] <Casper> no
[20:25:18] <Casper> why would they pick such inneficiant mean of knowledge?
[20:25:21] <z64555> more likely to use other communications protocols, unless they like the aesthetic of optical reading of printed material
[20:25:40] <Casper> they will just download the info from their central server
[20:26:35] <z64555> There's also the possibility of intentional prohibition of communication excluding sensory communication
[20:26:56] <z64555> sensory, as in light, touch, heat
[20:27:42] <Snert> a robot for a top sercret area, I suppose.
[20:28:14] <z64555> even then, you can use stuff like a flash card or cassette tape
[20:44:20] <rue_house> mmm data cassette
[20:45:11] <Casper> load ... play... enter.... error.... rewind, tone, volume, load, play, enter.... run
[20:58:44] <rue_house> wait... wati.... wait....
[23:54:28] <rue_bed> books would be more efficient if they used overlapped coloured text
[23:59:10] <Casper> and also if they would use all of the possible characters from all the languages
[23:59:26] <theBear> tv is free and twice as fast !
[23:59:27] <Casper> and convert that into multi-bytes per symbols!
[23:59:46] <Casper> tv is not free in UK
