00:02 rue_mohr I'm away to see the fireworks, later!
00:02 katsmeow-afk i'd like to point out that whoever the idiot was that drilled the holes to mount the threaded piece on my drill press, didn't drill it straight or centered, and the threading comes loose too
00:02 katsmeow-afk fireworks?
00:02 katsmeow-afk plus the hole thru the spindle weakens it
00:03 katsmeow-afk note on http://imgur.com/gBWPi there is no collar teen that threaded piece and the inner race of the bearing, so there's prolly vertical play int hat spindle as the shaft can slide up and down thru that bearing
00:04 parco katsmeow-afk: its a clausing, and they still sell parts
00:04 katsmeow-afk ok then , ask them for a chuck
00:05 parco idk if they sell the chucks, but i know they sent me a free manual for an old lathe i had
00:05 parco so we dont know exactly what would fit on that?
00:05 parco i read somewhere its a #2 M.T.
00:06 parco whats with that hole, is that a set-screw for something?
00:09 tsmeow-afk hands parco her glasses and a flash
00:10 tsmeow-afk also points up to the text she typed about that hole, apparently for no re
00:35 katsmeow-afk Can a single person apply for funding?
00:35 katsmeow-afk Yes, but the odds of being accepted are lower. A startup is too much work for one person.

00:38 parco anyone ever fab'd a magnetic coupler?
00:38 parco like this http://www.magnetomachinery.com/magnetic-coupling-2.htm
01:30 rue_mohr nope
01:31 rue_mohr what are you making?
11:11 IndianaRonaldo Under SEH Team
13:01 e_bed stret
13:02 m_itx notices rue_bed looking a bit ta
13:02 rue_bed nice day, I should set hte mowerbot out
13:02 rue_bed ah, no I have to fix one of its drive chains
13:02 rue_bed iirc it ripped the sprocket off
13:04 Tom_itx been cleaning shifters on my bike
13:06 j674 mower bot????
13:26 j083 Psychology?
14:52 rue_mohr we lack a mathematical operation for no relation
14:52 rue_mohr mowerbot, a robot that mows
14:53 rue_mohr not having a mathematical operator for no relation is like having a numbering system without 0
14:53 rue_mohr we have no way to say that A is in no way mathematically related to B
14:54 rue_mohr did you know that the mere act of walking across a room changes the orbit of pluto?
14:54 rue_mohr the universe is recording everything we do
14:55 ace4016 actaully, we do have math for that...
14:56 ace4016 it's part of set theory
14:56 ace4016 we do have numbering systems without 0 as well
14:57 rue_mohr so whats the mathematical operator for no relation?
14:59 ace4016 depends on what you mean by that
15:41 Skwint rue_mohr, I think the term is "orthogonal"
15:41 Skwint and there probably is an operator for that
16:17 snollux Hello. Can someone give me a resource for learning about the different types of basic articulation/motion for a robot or motors? What is it called when you have aluminum/metal guide rails and the robotic component travels across them linearly?
16:24 katsmeow-afk linear motion
16:24 katsmeow-afk aka, expensive
16:27 snollux katsmeow-afk: how could you make something like this move? http://www.pbclinear.com/Images/Items/tech_prod_GST.jpg
16:27 snollux seems like any rack-and-pinion set up would reduce smoothness and precision
16:28 katsmeow-afk worm drive or cogbelt and drive sprocket, depending on your requirements
16:29 katsmeow-afk possibly an air or hydraulic cylinder
16:29 katsmeow-afk depending on your requirements
16:29 snollux hrmm OK. I'd like to start learning robotics over the next couple of years, and maybe in 2 or 3 years I'd try to make some sort of CNC mill or 3D printer
16:29 snollux obviously I'm nowhere near educated or skilled enough to undertake such a project at this point
16:30 katsmeow-afk really? because they sell kits to diy
16:31 snollux yeah, but a little expensive. I was hoping to come up with my own design
16:31 snollux but I guess that's an option
16:31 snollux maybe I'd use a kit to build components for my own thing when I learn enough
16:32 snollux it's just that I haven't done anything aside from a little RC robot with a couple of servos
16:32 katsmeow-afk and you learned nothing from that?
16:34 snollux I learned quite a bit, but not high-precision, multi-axis articulation out of proper materials that would lend themselves to drilling metal
16:34 tsmeow-afk cannot tell by looking at the screen if someone learned somet
16:34 ollux was just using wood and
16:35 snollux aluminum and steel is intimidating, for some reason
16:35 katsmeow-afk oh, you don't do the actual drilling with anything but a drill bit, usually
16:36 katsmeow-afk aluminum is easy to drill and machine and bend, but hard to fasten parts togther well
16:36 katsmeow-afk steel is hards to drill or machine or bend, but easy to weld and key and pin togther well
16:37 snollux http://www.youtube.com/watch?v=ur6JlU3UBhU oh nice
16:38 snollux and http://www.youtube.com/watch?v=mPkwIG7og44&feature=related this looks awesome, from drawer slides
16:39 tsmeow-afk goes afk , and lets the otehr 63 people here
16:39 snollux haha ok :)
21:21 rue_shop Tom_L,
21:21 rue_shop Tom_L, you here?
21:21 rue_shop theBear,
21:21 rue_shop hello?
21:22 rue_shop ace4016, you use windows 7?
21:22 rue_shop furrywolf, you use windows 7 dont ya?
21:22 rue_shop Triffid_Hunter, you use windows 7?
21:24 Tom_L yes
21:24 rue_shop windows 7 antivirus software, suggestions?
21:25 Tom_L malwarebytes is one
21:25 Tom_L i use
21:25 Tom_L you got a bug?
21:25 rue_shop uncles laptop :)
21:26 rue_shop free?
21:26 Tom_L if you get one that takes over there's stuff you can load to stop it
21:26 Tom_L yes
21:26 Tom_L just a sec
21:26 Tom_L http://www.malwarebytes.org/lp/malware_lp?gclid=CN7F_pqqwLECFSHftgodLDYAIw
21:27 rue_shop heard of "live seccurity platinum" ?
21:27 Tom_L no
21:27 Tom_L i have another i use too
21:28 Tom_L i'm looking...
21:28 rue_shop will the free one remove viruses?
21:28 Tom_L yes
21:28 Tom_L spybot
21:28 ace4016 i use malwarebytes, microsfot security essentials, and spybot: search & destroy
21:28 Tom_L is another one
21:29 ace4016 MSE and spybot do weekly scans; MSE doesn't bog the system down with its real time projection (which I don't trust)
21:29 Tom_L http://www.safer-networking.org/en/spybotsd/index.html
21:29 ace4016 malwarebytes is just there when I suspect something might be there...but I don't do things to contract viruses :P
21:30 katsmeow-afk MSE has bogged my puters down badly at times
21:30 ace4016 only time it shows its presence in terms of performance is when its doing a scan
21:30 ace4016 i set my scans to run when I'm asleep though :P
21:31 Tom_L same here
21:31 ace4016 might help that I have 8GB of ram >_>
21:32 Tom_L also i use mbam for problems that won't let go
21:32 ace4016 rkill + mbabm works nicely; though i've only ever had to do that to other people's computers
21:32 ace4016 (worked tech support for a bit)
21:32 Tom_L same here
21:33 Tom_L usually one of the other laptops in the house
21:33 ace4016 crazy the stuff people download
21:33 Tom_L rue_bed i can put those on my server if you wanna dl them
21:33 Tom_L rkill and mbam
21:34 katsmeow-afk hmm, http://www.malwarebytes.org/mwb-download without registering?
21:34 Tom_L http://download.cnet.com/RKill/3000-8022_4-75221743.html
21:34 katsmeow-afk registering got me instant spam fromt hem
21:34 Tom_L you wouldn't get spam from me :)
21:35 katsmeow-afk the spam is why i posted the link
21:35 Tom_L oh
21:36 katsmeow-afk well damnit, i have no clue where FF put the file
21:37 Tom_L in the dl directory
21:37 Tom_L i changed that to ask me
21:38 katsmeow-afk i told it where to dl, but FF now quietly cancels all dls if you close that window, or if it has any problems with the dl, and if you click "retry" inthe dl manager, there's no record of where the dl went
21:39 Tom_L yeah i haven't figured that out either
21:39 Triffid_Hunter rue_shop: lol nope, haven't used windows in years
21:43 rue_shop its doing that thing where it wont run any program because -------.exe is 'infrected'
21:44 Tom_itx try rkill and mbam
21:46 katsmeow-afk as slowly as mbam is running, it could take most of a year to do most of my harddrives
21:47 katsmeow-afk er
21:47 katsmeow-afk as slowly as mbam is running, it could take most of a year to do each of most of my harddrives
21:58 katsmeow-afk mbam is using 100 megabytes, i got only 2gig, and often use most of that
21:59 Tom_itx it does take a while to run
21:59 katsmeow-afk according to this, it's doing 2,800 files per minute
22:00 katsmeow-afk it will take 24 hrs to do some folders
22:00 katsmeow-afk 23.81 to be more exact
22:03 katsmeow-afk nope, it will take longer, it periodically stalls
22:05 katsmeow-afk and if it's memory use doesn't flatten, i'llbe out of ram
22:32 katsmeow-afk what do you suppose it means that mbam flagged MSE?
22:47 katsmeow-afk it checks to see if MSE is turned off, if auto updates is turned off, if etc is turned off
23:09 rue_mohr katsmeow-afk, you dont use windows 7 do you?
23:16 Tom_itx rue_mohr did you get anywhere?
23:20 katsmeow-afk no
23:21 Tom_itx i never upgraded the laptops to 7 they're still running vista i think
23:21 Tom_itx i have the upgrades in a drawer somewhere
23:21 Tom_itx lacked printer drivers etc so i said no thanks
23:22 katsmeow-afk yeas, new restrictions, new code, new bugs, more cost in money and hardware
23:24 tsmeow-afk pats her VI
