01:05 rue_mohr2 now I simply copy and paste it onto the avr...
01:34 rue_mohr2 stich it into the other state machine....
02:04 rue_mohr2 on one of my computers somewhere there is a kermit session running thats showing the result of the avr firmware I just reflashed with the computer in the shop from the computer in my room
02:06 rue_house I found it!
03:04 rue_mohr2 I'm confused
03:04 rue_mohr2 I have a value, that I display as the user inputs
03:05 rue_mohr2 then when its done, I copy the value to antoher var and use the same function to display it, but the value is gone
03:50 rue_mohr2 haha! got it!
03:50 e_mohr2 colla
08:37 KongfuPanda_ hello
08:37 KongfuPanda_ can someone help me with wiring a relay please?
08:40 robopal say it, or give a link to your circuit if you have
08:41 KongfuPanda robopal, https://dl.dropboxusercontent.com/u/26776513/20140317_130723.jpg
08:41 KongfuPanda robopal, I have the mains and my heating tape (resistor)
08:42 KongfuPanda I tried connecting mains to terminals 11 and 12, and tape to 1 and 2, but nothing happened. I couldn't measure any voltage across 1 and 2
08:42 robopal ah I though it was a small one, for electronics
08:42 KongfuPanda robopal, I guess I am confused regarding wiring
08:43 KongfuPanda robopal, can you help me with this?
08:43 robopal I dont think so, not with this
08:44 KongfuPanda why not? do you think I need some other parts to be able to heat the tape?
08:46 robopal what about 6 and 7?
08:47 robopal no idea haven't seen one of those before
08:47 robopal but stick around, someone will know
08:49 KongfuPanda 6 and 7 are nothing
11:35 rue_mohr2 KongfuPanda,
11:35 rue_mohr2 your working it wrong
11:35 rue_mohr2 *but*
11:35 rue_mohr2 KongfuPanda, still here?
11:36 rue_mohr2 KongfuPanda, power goes to 11, 12 yes
11:37 rue_mohr2 KongfuPanda, a tempature sensor connects to 3 and 5 OR 5 and 4 depending what sensor you have
11:38 rue_mohr2 KongfuPanda, 1 and 2 are to control a heater DRIVER, not a heater directly
11:39 rue_mohr2 AAAAAAAAAAAAAAAAA I THINK THIS VIRUS IS GONNA KILL ME
11:48 GuShH_ Tom_itx: was thinking about the flex drive shaft for the mill... it has to be telescoping as well
11:48 GuShH_ because as the table goes up or down, it needs to extend or retract.
11:48 GuShH_ some are splined, others have keyways... but I think square tubing could work just fine
11:48 GuShH_ a little slop wouldn't matter I guess
11:49 GuShH_ as long as you back out accordingly
11:49 GuShH_ I wonder if the original shaft doesn't have massive backlash anyway, not like I've got the option to buy one though
11:49 GuShH_ here's another machine where you can see the shaft http://img.photobucket.com/albums/v470/haplesspeanut/Smilies/DRVSHFT1.jpg
11:50 GuShH_ that one has a cute norton gearbox, modular design same as used on their lathes... cool
11:50 rue_mohr2 gush
11:50 rue_mohr2 easy way of doing it using some pipe and pins
11:51 rue_mohr2 shall I see if I can find a pic?
11:51 GuShH_ rue_mohr2: for the cardans I can use existing ones
11:52 GuShH_ it needs two, I was thinking the ones used in sockets could work fine
11:52 GuShH_ good smooth joints
11:52 GuShH_ otherwise I could find something small enough from a vehicle steering column
11:52 GuShH_ but they're quite chunky by comparison
11:52 rue_mohr2 http://eds.dyndns.org/~ircjunk/robots/buddy_II/p1040833.jpg
11:52 GuShH_ I don't have the machine yet, I'm just figuring things out
11:52 rue_mohr2 look @ bottom
11:52 rue_mohr2 I'll try to find better
11:52 GuShH_ square tubing for the telescoping part would work fine IMO
11:53 GuShH_ 3mm steel if possible
11:53 rue_mohr2 http://eds.dyndns.org/~ircjunk/robots/buddy_II/p1040836.jpg !@#$#$% so close!
11:53 rue_mohr2 GuShH_, its WAY easier than that
11:53 GuShH_ what?
11:53 GuShH_ it needs to be telescoping.
11:53 GuShH_ not a fixed length
11:53 rue_mohr2 how much?
11:53 GuShH_ I don't have the measurements.
11:53 GuShH_ probably 10 inch travel
11:53 rue_mohr2 1mm or 45cm
11:54 GuShH_ so I thought square tubing...
11:54 rue_mohr2 oh, k
11:54 GuShH_ they used keyways or splines
11:54 GuShH_ those are not easy to make
11:54 rue_mohr2 much torque?
11:54 GuShH_ depends on what you are doing :p
11:54 rue_mohr2 milling machine?
11:54 GuShH_ if I had a picture of the original part I could base it off of that
11:54 GuShH_ yes, the power feed transmission
11:55 rue_mohr2 ooh yea, they usually use a spline shaft with two universals
11:55 GuShH_ they seem flimsy, based on pictures of other machines
11:56 GuShH_ right a couple U socket joints was my idea, for the cardans.
11:56 GuShH_ called universal joint by some..
11:57 GuShH_ but you get the idea, they are nice and sturdy
11:57 GuShH_ that could be welded or fastened to the telescoping shaft
11:57 GuShH_ it should work with square tubing.
11:57 GuShH_ probably not the safest or prettiest of solutions
11:58 GuShH_ rue_mohr2: splines or keyways are no-no for me, but if you have other ideas I'll gladly look em up
11:58 GuShH_ I guess I could get the keyway machined by someone else
11:58 GuShH_ on a big thick shaft
11:59 GuShH_ but that's two machined parts, adds to the cost vs two square tubes with welded couplers
11:59 GuShH_ problem with square tubing is... the weld joint
12:00 GuShH_ it usually makes a tight fit impossible without removing the weld first
12:00 GuShH_ my steel supplier doesn't carry anything without weld / seams
12:00 GuShH_ other than some pipes
12:00 GuShH_ I could somehow broach the seam out... or sacrifice a long chisel...
12:01 GuShH_ at least he was honest enough to tell me about the missing part
12:01 rue_mohr2 http://upload.wikimedia.org/wikipedia/commons/b/b6/Horizontal_milling_machine--Cincinnati--early_1900s--001.png
12:01 rue_mohr2 haha I found a pic!
12:03 rue_mohr2 its interesting how new machines are designed more around doing one-off's
12:03 GuShH_ ohh that's a lovely machine
12:03 rue_mohr2 back in the day, when you had to set a machine up for a job, it took a while
12:03 GuShH_ southbends and bridgeports plus cincinnati... a boy's dream
12:03 GuShH_ that's a universal milling machine
12:03 GuShH_ sure it took time to setup
12:03 GuShH_ but you could do just about anything
12:04 GuShH_ oh it's just horizontal doesn't seem to be universal
12:04 rue_mohr2 you know how to use your lathe to draw cuts?
12:04 GuShH_ ie. no vertical head coupling
12:04 GuShH_ although I kinda see 3 of the 4 mounting holes
12:04 rue_mohr2 you can key a shaft
12:04 GuShH_ I'm not like you.
12:04 GuShH_ I won't abuse it or spend countless hours broaching away tiny amounts of steel when I can use square tubing instead!
12:04 rue_mohr2 it was taight to me by and old machinist
12:05 rue_mohr2 oh yea, well you could do that too
12:05 GuShH_ I know, but it's abusing the poor machine
12:05 rue_mohr2 ~
12:05 GuShH_ ?
12:06 SlaveToTheSauce !

12:06 SlaveToTheSauce &&
12:07 GuShH_ I like how they depicted the two t slot nuts for the vise in that illustration, now adays all manuals and pictures are for "illustrative reasons" they do not depict reality anymore.
12:07 GuShH_ but back in the day it was GOSPEL
12:07 GuShH_ you got what you saw, because they were mostly in catalogs
12:07 GuShH_ and if you didn't get all the parts depicted, you could complain and get the missing parts.
12:08 GuShH_ now they just say "oh that's an outdated manual for another model" "oh it's not included in this version"
12:08 GuShH_ bullshit, chink loving bastards!
12:08 ShH_ turns into a massive b
12:09 GuShH_ rue_mohr2: nice
12:09 GuShH_ there are still shops around the world using power distribution with leather belts
12:09 GuShH_ massively noisy and requires a lot of maintainance
12:09 rue_mohr2 just the thought of engineering a building with all the drive shafts
12:09 GuShH_ I'm not sure if they used graphite bushings or if it was something more exotic
12:10 GuShH_ something that had to be cast in place, not sure which metal
12:10 GuShH_ I don't recall :(
12:11 SlaveToTheSauce i've had the pleasure of visiting a preserved steam-powered sawmill
12:11 rue_mohr2 cool
12:11 GuShH_ I like the rotating governors on those steam engines
12:11 SlaveToTheSauce yeah that's where control theory came from
12:12 GuShH_ it's also an instant darwin award for idiots.
12:12 rue_mohr2 they have that kinda "WEEEE" thing going on
12:12 GuShH_ Seen a few of those used in decoration
12:12 GuShH_ most people don't even know what they are
12:13 GuShH_ "kardashian sex toy?"
12:16 GuShH_ woah at least $200 in moving the machine...
12:16 GuShH_ I could use rue's truck for this!
12:16 GuShH_ rue_mohr2: ever figured out the oiling problem in that engine?
12:18 GuShH_ I kept thinking the other day and it must be the parts are all worn out of spec, which is why there's no internal pressure... a pump alone won't do much to force oil through the right passages if the parts are not within tolerance. Likewise oil does little when tolerances are gone, since the right thickness film cannot be sustained between the mating surfaces :(
12:21 ShH_ wonders if the clutch w
13:23 f00bar80 i'm using micro servo but the horn mounting screws after running three or 4 times, they become loose, the servo motor is nylon not metal, is there a way to lock the screw to the horn ?
13:27 GuShH_ f00bar80: loctite
13:27 GuShH_ blue one
13:27 GuShH_ or just a tiny drop of super glue will do
13:28 f00bar80 but i've been told, that loctite blue doesn't work for nylon output
13:28 GuShH_ sigh
13:29 GuShH_ use a split washer then?
13:29 SlaveToTheSauce the answer is hot glue
13:29 SlaveToTheSauce the answer is always hot glue
13:29 GuShH_ no, we're not females.
13:29 GuShH_ hot glue is not an option for non females.
13:29 SlaveToTheSauce that is patently false
13:29 GuShH_ you are growing tits as we speak.
13:29 SlaveToTheSauce that would be pretty sweet but also false
13:29 GuShH_ I think pot will help you with that
13:30 SlaveToTheSauce see above
13:31 f00bar80 i tried gray silicon , but always the horn isn't binded to the beam i'm attached to it
13:31 GuShH_ SlaveToTheSauce: some of that plumbing glue for abs piping will definitely stick to his nylon toy.
13:31 SlaveToTheSauce yeah or perhaps cyanoacrylate
13:31 GuShH_ I already said super glue!
13:31 SlaveToTheSauce oh yes
13:32 GuShH_ but he should try a mechanical method if nothing else works
13:32 GuShH_ split washers will help you bind the threads
13:32 GuShH_ as it tensions them
13:33 ShH_ emailed the paint store thinking they would reply promptly... how na
13:34 SlaveToTheSauce i suspect the looseness is the threads chewing through the nylon in the first place
13:34 SlaveToTheSauce ie adding tension will make it worse
13:35 SlaveToTheSauce those servo horns arent really made to take much punishment, they're made to thread a wire through to push a little piece of foam around
13:36 GuShH_ why are they loose?
13:36 GuShH_ when I thread delrin it's a nice tight fit
13:36 GuShH_ surely something somewhere went wrong with his parts?
13:37 GuShH_ SlaveToTheSauce: I know, I've been involved in RC since the age of 6-7
13:37 GuShH_ But to be fair, quality has degraded for "inexpensive" servos, a lot.
13:37 SlaveToTheSauce yeah certainly
13:37 SlaveToTheSauce i have a bunch of $2 9g servos
13:37 GuShH_ heh I got some of those and they are.... horrible
13:37 SlaveToTheSauce and they rule for the price but you certainly get what you pay for
13:37 GuShH_ haven't found a use for them
13:38 GuShH_ oh I didn't pay anything for them!
13:38 SlaveToTheSauce ive been using them to test my hexapod electronics
13:38 GuShH_ mine jitter a lot
13:38 SlaveToTheSauce / source
13:38 GuShH_ and never quite return to the same place
13:38 GuShH_ it's not interference, since a proper standard servo works fine by comparison
13:38 GuShH_ I think it's the low quality feedback pots they use
13:38 SlaveToTheSauce because it's much nicer to use them than something that can injure me or pull enough current to catch fire if i fuck up
13:38 GuShH_ they are noisy, maybe a tiny cap in there would help
13:39 GuShH_ I just thought about using one to lower/raise the electrode for an EDM but... even with reduction it's not going to be much use
13:39 GuShH_ so I'm sticking with steppers
13:39 SlaveToTheSauce mg996R are pretty ok and cheap
13:40 GuShH_ I heard good things about those
13:40 SlaveToTheSauce but yeah obviously a stepper would be the best
13:40 GuShH_ I need very fine movements
13:40 GuShH_ but I'm using a delrin nut with m6 stainless threaded rod, because that's what I have...
13:40 SlaveToTheSauce mmyep not gonna get that from cheap digital servos
13:41 GuShH_ starting out with mdf for the prototype, who said I had to use metal for the first attempt!
13:41 SlaveToTheSauce hey if a chinese cnc can do it so can you
13:41 GuShH_ will also attempt to use delrin for bushings, to create the linear bearings.
13:41 GuShH_ which chinese cnc is built like this?
13:41 ShH_ looks wor
13:42 SlaveToTheSauce [12:50:06] <rue_mohr2> http://probotix.com/FireBall_X90_desktop_cnc_router/
13:42 GuShH_ thing thing only has to go up and down and be sturdy enough not to move the electrode around
13:42 GuShH_ oh that thing
13:42 SlaveToTheSauce is a selfmade plastic bushing really going to do better than a $2 lm88u?
13:43 GuShH_ 2 for you is 20 for me, I live in Argentina.
13:43 GuShH_ and I can ream it to 8mm, then machine the rods to size, or get the right size.
13:43 GuShH_ it's not going to see much use.
13:44 GuShH_ again, it's just a single axis.
13:44 SlaveToTheSauce i wanna get some of those fancy teflon ones the guy in #reprap was making but they're super pricey
13:45 GuShH_ why are they pricey?
13:45 GuShH_ ptfe is not terribly expensive and machines easily
13:45 SlaveToTheSauce low volume manufacturing probably
13:45 GuShH_ you just need to ream any bushing you are making
13:45 GuShH_ otherwise a twist drill won't get you there.
13:45 SlaveToTheSauce oh that reminds me i found a sweet bearing supplier this weekend
13:45 GuShH_ heh I found one the other month but it's rather far away
13:45 GuShH_ they do carry just about anything you want though
13:45 SlaveToTheSauce http://www.ebay.com/itm/390773907375
13:46 ShH_ is talking about a physical store you can walk into and talk to real pe
13:46 GuShH_ those, much to your surprise, exist!
13:46 SlaveToTheSauce you and your 'real stores'
13:46 SlaveToTheSauce we don't have any of those here, except ones that charge obscene amounts
13:46 GuShH_ GET OFF MY LAWN
13:46 GuShH_ I got some 608z from china not long ago
13:46 GuShH_ back when I could order from china...
13:46 GuShH_ they are horrible.
13:47 GuShH_ they already come with play!
13:47 SlaveToTheSauce yeah the quality really varies
13:47 SlaveToTheSauce i got some rather nice ones and some shitty ones and some ok ones
13:47 GuShH_ these came in a transparent plastic tube about 10 of them
13:47 SlaveToTheSauce my nice ones came like that!
13:47 GuShH_ forgot the brand... but it's a china one
13:47 SlaveToTheSauce anyway i ordered a fuckton of 623zz's from this guy, will see how that works out
13:48 GuShH_ compared to the good stuff from SKF these are horrible
13:48 GuShH_ I do need to get some tiny thrust bearings for the lathe
13:49 GuShH_ those can be any quality, even the worst ones will be better than nothing.
13:51 SlaveToTheSauce i ordered like $25 worth so even if they're shit i will find bliss in their quantity
13:51 GuShH_ god damn people changing their orders
13:51 GuShH_ now I know how the chinese feel
14:09 rue_mohr2 during the 2 hour wait in line at the medical clinic I got worse than I been yet
14:44 rue_mohr2 would everyone who said yes to youtube video stabilization please delete their videos and re-upload without it, thankyou.
14:47 SlaveToTheSauce i wish it was a clientside option
14:47 SlaveToTheSauce cause very occasionally it is desirable
14:47 SlaveToTheSauce but yeah usually it looks fucking awful and nauseating
14:52 rue_mohr2 if you have a bench supply with a serial control terminal
14:52 rue_mohr2 30V 5A supply
14:52 rue_mohr2 and you tell the output to go to 99V on the terminal
14:52 rue_mohr2 should it ignore or go to max?
14:53 SlaveToTheSauce i'd say just cap it
14:53 SlaveToTheSauce i'd also say ALL increases should be verified
14:53 rue_mohr2 cap the user? for entering an invalid number? kinda harsh
14:54 rue_mohr2 *woosh*
14:54 SlaveToTheSauce i got the joke
14:54 SlaveToTheSauce just didn't feel like entertaining it
14:55 rue_mohr2 my ANSI serial interface is going nice
14:55 rue_mohr2 I have colour!
14:55 rue_mohr2 http://eds.dyndns.org/~ircjunk/projects/newpower/Interface.png
14:56 rue_mohr2 thats serial right from the avr
14:56 rue_mohr2 I'm connecting with kermit
14:58 rue_mohr2 I got number entry working last night
15:00 rue_mohr2 if the total draw from the main supply is more than 6A I wonder if I should flash a yellow message saying that the main supply is in danger of exploding...
15:00 rue_mohr2 its a 10A chinese supply
15:02 SlaveToTheSauce i have a 20A one i've hit capacity on for hours at a time
15:02 SlaveToTheSauce thankfully chinese and garbage aren't entirely synonymous
15:02 rue_mohr2 indeed
15:03 rue_mohr2 tho if something is made in NA its usually the same price as a good chinese one
15:03 rue_mohr2 so I'v found
15:05 SlaveToTheSauce i havent pushed my 30A one past 20 or so yet
15:06 rue_mohr2 I figure to some degree they count on these things, you ever looked at welder ratings?
15:13 SlaveToTheSauce yeah which work fine with a 0.01 duty cycle
15:14 SlaveToTheSauce what you should really do is put a thermistor on the case (which all the semiconductors that matter are probably coupled to) and the biggest inductor
15:16 rue_mohr2 if I use big enough fets I dont need heatsinks
15:16 rue_mohr2 :)
15:17 rue_mohr2 ... well I do on the fet drivers
15:20 SlaveToTheSauce i mean on the dc supply
15:20 SlaveToTheSauce and it is my experience that the inductors are usually the worst heaters
15:21 SlaveToTheSauce because they usually have more resistance than nice fets in the first place, and the cores will dissipate some energy as heat due to magnetic hysteresis
16:09 SlaveToTheSauce oh look nao is $8000 now
16:09 SlaveToTheSauce and it's still a ripoff
17:45 rue_mohr2 SlaveToTheSauce, you still here?
17:47 SlaveToTheSauce ya
17:47 rue_mohr2 that only generates a control signal for how much the heater should be run, it DOES NOT RUN TEH HEATER
17:47 rue_mohr2 ok?
17:48 rue_mohr2 pins 1 and 2 are for communicating with the heater driver
17:49 rue_mohr2 just like an arduino needs a motor driver
17:50 GuShH_ arduinos also need desperate grown men or naive children to work
17:51 rue_mohr2 I think SlaveToTheSauce is ignoring me
17:51 Tom_itx rue_mohr2, nasa wants you! http://www.electronicproducts.com/Computer_Peripherals/Systems/Help_wanted_NASA_looking_for_coders_to_hunt_dangerous_asteroids.aspx
17:51 SlaveToTheSauce wat
17:52 GuShH_ SlaveToTheSauce: but.. which type of sauce?
17:53 SlaveToTheSauce GargantuaSauce
17:53 GuShH_ theBear: around? where are you man
17:53 GuShH_ and where's RifRaf
17:56 GuShH_ rue_mohr2: which type of plastic can I use for hot water without having to worry about deformation?
17:56 GuShH_ 100°C or so
17:56 GuShH_ 1 inch or 1.5 inch
17:56 Tom_itx delrin
17:56 GuShH_ no, but any common pipes?
17:57 GuShH_ not pvc, I think it would go mushy
17:58 GuShH_ delrin would work, but I can't find any with graphite load
17:58 GuShH_ will ABS suffice?
17:59 GuShH_ the black pipes used in houses
17:59 GuShH_ I was looking at PEX but I'm not sure about it's properties
17:59 GuShH_ and whether it's machinable
18:00 ShH_ could easily use aluminum but is trying to be extra c
18:05 rue_mohr2 GuShH_, I think that pex actually get harder with heat
18:06 rue_mohr2 pex machines fine
18:07 GuShH_ I'm not sure they sell PEX around here though
18:07 rue_mohr2 if its not pex, there IS pipe that hardens with temp
18:07 GuShH_ how does it get harder with heat?
18:07 GuShH_ that puzzles me
18:07 ShH_ p
18:07 GuShH_ something about the polymer chains getting all horny with the heat, but still...
18:08 rue_mohr2 call a BIG plumbing company, as if they can supply you some
18:08 rue_mohr2 I was talking to a plumber, he was saying that the stuff thats meant for high heat will actaully harden
18:09 rue_mohr2 I have some of the heating pex, if it does get harder, it must 'relax' first, cause when they are warm they are much more workable
18:27 GuShH_ hrm
18:27 GuShH_ I might go for aluminum, unless I can find a reason other than cost to use ABS or similar
18:41 rue_mohr2 what are you making?
18:48 GuShH_ rue_mohr2: a nothing bot
18:50 rue_mohr2 aaah
18:50 rue_mohr2 working your way up to the something bot?
18:52 GuShH_ you betya
18:52 GuShH_ what colour should I paint the swimming pool?
18:52 GuShH_ blue or light blue? heh
18:55 causative black and yellow stripes
18:55 GuShH_ wtf
18:55 causative paint it blue with clouds and the sun on the bottom
18:55 GuShH_ no
18:55 GuShH_ that's what the sky is for
18:57 causative hire a professional artist to paint something cool in it
18:57 GuShH_ if you're paying sure
19:02 causative light blue then
19:04 GuShH_ causative: why?
19:05 causative it's a warmer color, dark blue suggests deeper colder water
19:06 GuShH_ good point, more or less
19:06 GuShH_ a darker frame around the top portion would work nicely with the lighter blue
19:13 rue_mohr2 GuShH_, something cool, paint ice all the way around just over the water line
19:14 causative clear ice cube pool toys and a giant straw
19:18 rue_mohr2 then the painting should have a cherry?
19:25 GuShH_ I need some of the drugs you guys are taking
19:26 GuShH_ rue_mohr2: doing it right is not easy, these paints are thick as hell, so you can't easily airbrush them
19:26 GuShH_ you would need a clear protective coat if you use any other type of paint, that has to withstand the chlorine and uv rays all day long
19:28 GuShH_ I would paint the water line in contrast to the main colour though
19:28 GuShH_ just to give it an extra touch.
19:28 GuShH_ needs some work done first, before I can paint it
19:28 GuShH_ gotta add a skimmer and all the plumbing
19:38 rue_mohr2 I was joking

19:39 rue_mohr2 you know whats scarry about that
19:40 rue_mohr2 it seems to imply that if brain activity stopped for long enough, every cell would lose its threshold and there would be no data left
19:40 ace4016 amensia!
19:43 peepsalot anyone familiar with calculating tooth profiles for involute spur gears?
19:44 rue_mohr2 I might have been once upon a time, there is software for that now
19:45 peepsalot i've read a few explanations for the common case, but I'm wondering about trying to add teeth along a more arbitrary curve than just a circle
19:46 peepsalot rue_mohr2, i'm interested in writing my own software for it
19:48 peepsalot like some of the spirograph guide shapes for example http://www.samstoybox.com/toypics/SpirographBox86.jpg
19:55 rue_mohr2 there are a number of javascript profilers you might want to start with looking at if you need
20:10 ShH_ regains his interest in
20:14 GuShH_ rue_mohr2: who the hell is Kevin Smith?
20:15 GuShH_ that fat ass is always wearing the same thing!!!
20:40 Tom_itx peepsalot the one to talk to about that would be archivist in #linuxcnc
20:40 peepsalot ok, thx
20:42 Tom_itx he's in england
20:42 Tom_itx dunno the time there
20:44 ace4016 about 2:30-3:30
20:44 GuShH_ Tom_itx: time for a cuppah tea
20:45 Tom_itx great idea

20:45 Tom_itx if you can make it
20:45 GuShH_ I pass.

21:51 causative are there a lot of legged robots with several centrally placed motors and cords/cables leading out to pull on the joints?

22:15 MrCurious autopilot, plane vanish, crash, aliens, crimea, russia, 130% of the vote in and ....
22:15 MrCurious news sucks this week
22:18 Faeks And detecting gravitational waves?
22:21 MrCurious thats greaat news
22:21 MrCurious how soon can you have it weaponized?
22:22 MrCurious and would one weaponize it as a programmabe blck hole phenomenon or as a programmable repulsion anti black hole
22:22 MrCurious thinking the latter would be way cooler
22:24 Faeks I do hope you are not serious
22:25 MrCurious isnt that how it works. new phenemon discovered, physists model it,, engineers make it workable, militaries weaponize it...
22:26 Faeks I think that's a cynical approach
22:27 MrCurious is it wrong?
22:27 Faeks Also exaggerated
22:27 peepsalot <rue_mohr2> from what I can tell, its fishing line and beads
22:27 peepsalot i've seen that before, its a really fancy bike shifter/brake cable
22:27 rue_mohr2 did you see the link I posted before I sadi that?
22:29 peepsalot the links in the cable housing are all aluminum i believe, for uber lightweightedness
22:30 Tom_itx peepsalot, did that help?
22:30 peepsalot http://www.alligatorcables.com/i_link.html i think this is the stuff
22:31 rue_mohr2 huh
22:32 rue_mohr2 its for bikes!?
22:33 peepsalot looks like the same stuff to me, why not
22:34 peepsalot Tom_itx, what, you mean archivist? yeah a bit.
22:34 peepsalot i just ordered a book on gears anyways
22:34 Tom_itx i know he's been working on their geometry for a while
22:35 Tom_itx cut a few
22:55 GuShH_ rue_mohr2: here's the mockup for the single axis edm http://gushh.net/tmp/edm3.jpg but I'm going to change the drive and I need to figure out the rails. might end up using 608 bearings on alu extrusions, don't be mean.
22:59 GuShH_ need a reduction for the drive
22:59 GuShH_ already built half of the carriage bit
23:02 GuShH_ why is tom laughing his ass off on the floor? and why is rue turning blue?
23:20 GuShH_ ohhhh a 10 or 13mm jacobs chuck on the base would be ideal, but they're too tall :(
23:53 rue_mohr2 my suggestion would be to only use one of the siders as a 2d ref, to make the other one only 1d so there is no binding in it, not even at the picometer level
23:54 rue_mohr2 I just rebuilt my heater, I decided to just split the bushings, they are spherical and a compresson spring keeps them up against the shaft, no more damn rattling
23:55 rue_mohr2 the time is
23:55 rue_mohr2 9:30
23:55 rue_mohr2 at 8 I took an advi, next will be 12
