00:28 katsmeow-afk gd fastenal, they list some things as disks, and other things as discs
00:38 katsmeow-afk ok,,,, cutoff / zipdisks for handheld "body grinders" are called "slicers"

00:41 katsmeow-afk $3.27 per 6" dia .040 thick for a 5/8 shaft
00:43 katsmeow-afk http://stores.ebay.com/TryC2/_i.html?_nkw=norton&_armrs=1&_from=&_ipg=&_trksid=p4634
00:43 katsmeow-afk those are the 4" you prefer
00:43 katsmeow-afk the 6" seem to last me 4x or more, and cut faster
00:47 rue_house higher surface velocity
00:47 tsmeow-afk
00:47 rue_house can the grinder take hte extra torque tho
00:48 katsmeow-afk if you don't bear down it
00:48 katsmeow-afk it you hear it bog dow it's eitehr binding or you are pushing too hard, and my grinders are 80% the harborfreight on-sale $19 versions
00:49 rue_house ooooh, I want some ebay toys
00:49 rue_house gearbox or windings give first?
00:49 katsmeow-afk i keep one for wirebrush, one for grinding, one for cutoff, and i picked up something else for sanding
00:49 rue_house I have two right now, one cutoff and one sanding
00:50 rue_house I lost one, it was grinding
00:50 katsmeow-afk strangly, the 4 screws holding the gearbox output bearing losten
00:50 rue_house it seems to help to dump gear oil in there
00:50 rue_house ah
00:50 rue_house I know what one
00:50 katsmeow-afk yeas, very important, greas.oil those things before you use them
00:50 katsmeow-afk however, if the grease is too thick, that will slow the motor down too
00:51 rue_house gear oil
00:51 rue_house the heavy stuff
00:51 katsmeow-afk if i had 180wt, i'd use that
00:51 katsmeow-afk 90 gear oil seems thin for these
00:51 rue_house I was surprised it didn't leak out
00:51 katsmeow-afk i add a dollop of grease, and then some 90
00:52 rue_house I still have $80 of a holiday bonus
00:52 katsmeow-afk too many gearboxes i have opened have no lube on the teeth, it's all packed like hard soap in the gearbox corners
00:52 rue_house what do I want?
00:53 rue_house time... $80 might get me about 3 hours
00:54 katsmeow-afk you wanna cnc something, like Tom did
00:54 rue_house I just got PID control working for encoder + dir/step -> motor
00:54 rue_house I have to apply it to the new cnc machine
00:55 rue_house as part of that I need to assemble 2 more motor controllers
00:55 katsmeow-afk see, the problem is you need so many custom parts for the 12ft mecha, you'lltire out making tem all by hand
00:55 rue_house not so mcuh
00:55 katsmeow-afk just count the finger jonts, it's a lot of work!
00:56 rue_house so far its a lot of premade stuff
00:56 katsmeow-afk really? when do we see pics of it carrying the trash out?
00:56 rue_house the maecha only has 3 digits too
00:56 rue_house so far its in a box under the shelf at the back of the shop
00:57 katsmeow-afk oh
00:57 rue_house I have to build the control cage first
00:58 katsmeow-afk http://www.ebay.com/itm/Blackstone-0854420-cutting-wheels-6-x-040-x-7-8-Type-1-BOX-OF-100-NEW-/171173240149 but it's only $2.50 each disc!!
00:58 rue_house iirc I get them for a little over $1 ea from a shop in vancouver
00:59 katsmeow-afk those??
00:59 rue_house I need a parting tool holder, where are those?
00:59 katsmeow-afk tool post
00:59 rue_house http://www.ebay.com/itm/CLAMP-TYPE-LATHE-PARTING-TOOL-COMPATIBLE-WITH-MYFORD-LATHE-from-Chronos-/300950584819
00:59 rue_house hmm
01:00 katsmeow-afk the 4" and 4.5" are $1 each in several places, but not the bigger disks
01:00 rue_house damn, I'm nodding off again
01:03 rue_house Lola8088, goodnight
01:37 TELunus Rue, I'm in a controls course at the moment (in fact I should go to bed, my exam is tomorrow), and the prof really seems to hate PID. He seems to much prefer complicated controllers like pole placement.
01:40 rue_bed I. is stupid, takes a lot of work to make work right
01:40 rue_bed I got PD working really well
01:41 rue_bed I dont know of loop control means that classify as 'pole placement'
01:41 rue_bed is that like working out the resonance and making a custom filter?
01:42 rue_bed which I suppose is placing 0's over your poles...
01:43 rue_bed TELunus,
01:52 katsmeow-afk there, emptied anotehr paint can
01:54 katsmeow-afk in the olden daze, i'd just set a error gain, the slope of the go signal, and the end-of-travel limit slopes
01:54 katsmeow-afk and max speed
01:56 katsmeow-afk you didn't set a pid for dealing with inertia, you set the main controller: wanna stop here? then turn it off here and it will follow the off-slope down to zero, controled by the error amp
01:57 katsmeow-afk didn't matterif power or braking was needed, the error amp followed the off-slope, it stopped where you said to
02:00 katsmeow-afk what happenes when you hang out with stupid humans ==>> http://www.foxnews.com/us/2013/12/09/indiana-hero-teen-killed-in-shooting/
02:54 katsmeow-afk In a critical article former Navy Secretary John Lehman wrote "[a]t least [the F-22s] are safe from cyberattack. No one in China knows how to program the '83 vintage IBM software that runs them."[172]

06:38 katsmeow-afk either i cannot sleep, or i cannot stay awake
07:09 katsmeow-afk remembering stuff i saw in the early 1960's, leftovers of ww2, and it's just a lil breathtaking in a way that those things were less than 20 yrs old when i saw them, put there during ww2
07:30 katsmeow-afk hmm, Metallica played a concert in Antarctica , no charge, it was freeze for all
07:45 katsmeow-afk Over the past two years, the company reports that it has racked up 368 drive years with the enterprise systems—primarily Dell PowerVault and various EMC solutions—and 14,719 drive years with consumer-grade technology. In that time, it reported 17 enterprise-class failures and 613 consumer failures, which produces an annual failure rate of 4.6 percent and 4.2 percent, respectively. So with lower costs and better reliability, why bother with an
08:45 katsmeow-afk Bromism is caused by a neurotoxic effect on the brain which results in somnolence, psychosis, seizures and delirium.[2]
08:46 katsmeow-afk Bromide has a very long elimination half-life of 9–12 days, which can lead to excessive accumulation. Doses of 0.5-1 gram per day of bromide can lead to bromism.
08:46 katsmeow-afk One case reported that a man who consumed two to four liters of a soda containing BVO on a daily basis experienced memory loss, tremors, fatigue, loss of muscle coordination, headache, and ptosis of the right eyelid,
08:46 katsmeow-afk In the United States, BVO was designated in 1958 as generally recognized as safe (GRAS),[2] but this was withdrawn by the U.S. Food and Drug Administration in 1970.[3]
08:47 katsmeow-afk BVO is used in Gatorade and Mountain Dew manufactured by PepsiCo; Powerade, Fanta Orange and Fresca made by Coca-Cola; and Squirt, Sun Drop and Sunkist Peach Soda, made by the Dr Pepper Snapple Group.[6] and otehr soft drinks
08:47 katsmeow-afk Standards for soft drinks in India have prohibited the use of BVO since 1990
08:47 katsmeow-afk The use of BVO as a food additive has been banned in Japan since 2010
08:48 katsmeow-afk In the European Union, BVO is not on the current EU-approved additives list.
08:48 katsmeow-afk BVO is currently permitted as a food additive in Canada.
08:48 katsmeow-afk Neurological and psychiatric symptoms are widely varied and may include the symptoms of restlessness, irritability, ataxia, confusion, hallucinations, psychosis, weakness, stupor and, in severe cases, coma.[1]
08:51 tsmeow-afk ponders a new sticker on 2-liter bottles: "this drink won't poison you like some others m
10:49 TELunus Rue, in pole placement controllers you find the transfer function of the system you're controlling, and then choose a controller that has a transfer function such that the full closed loop system has a characteristic equation that you like. (in essecence you place the poles of the closed loop system where you want them).
10:52 TELunus katsmeow-afk: Don't put that sticker on alchohol.
12:45 katsmeow-afk not on alcohol? wait, you have 2-liter bottles of alcohol in Canadia?
14:27 katsmeow-afk prolly good i don't have money, i'd be doing things like duct taping mini-itx to shovels and gift wrapping the shovel, putting memory upgrades in bottle of wine,
14:28 katsmeow-afk i once sent someone a goblet that looked like it was horribly shattered and was barely holding itself together (it was made that way)
14:30 katsmeow-afk stuffing the dust bag on an old dead vac cleaner from the scrap yard with dollar bills
14:31 katsmeow-afk robot cat barfs up a hairball containing a ring
15:52 katsmeow-afk i peeled open a starter motor, which had been locked up, expecting rust and ruination,,,,,,, the problem was the grease in one sleeve bearing has turned to glue, the shaft was glued into the bearing by dried grease, there was no rust anywhere
15:55 katsmeow-afk i used two screwdrivers to pry it apart
15:56 katsmeow-afk good news vs bad news : the output end of this motor style is the same as the other style, the brush holders are better designed, the brush end uses the same bearing as the otehr end (qty discount), so........ the end bell at the brush end is different

16:11 katsmeow-afk “[The] research is truly cutting edge and leading the world in terms of providing direct sensory feedback to amputees,” says Jack Judy, director of the Nanoscience Institute for Medical and Engineering Technology at the University of Florida in Gainesville.
16:11 katsmeow-afk Judy recently served as a program manager for the Defense Advanced Research Projects Agency, where he ran a program that sought to improve the performance and reliability of neural interfaces used to control prosthetic limbs for soldier amputees. At least 1,715 soldiers suffered amputations in the wars in Iraq and Afghanistan.

18:29 katsmeow-afk anyone interested, there's a batch of 7603 scopes with all plugins, ready to go, on ebay for under $50 atm
18:30 katsmeow-afk they are not mine, and i am not bidding on them
19:11 rue_house Lolina8088,
19:13 katsmeow-afk rue_house,
19:13 rue_house ma has something for moria!
19:14 rue_house do you have a tree yet?
19:14 rue_house I had an idea
19:14 tsmeow-afk wraps lites on rue's
19:14 e_house watches his idea ligh
19:14 katsmeow-afk oooooooooo
19:15 katsmeow-afk we were discussing oil/greaselast nite, today i ran into a grease situation that locked up a motor
19:15 rue_house ?
19:15 katsmeow-afk scrollup
19:15 rue_house wow
19:16 rue_house I dozed off listening to you talking about it
19:16 rue_house for some reason you sounded alot like me
19:16 katsmeow-afk er,, umm, is that good?
19:17 rue_house it means I'm haluciniating as I'm dozing off
19:17 rue_house which I do
19:17 rue_house I think my eyes are open and sudeently reazizde they are closed and what I'm hearing isn't real
19:18 katsmeow-afk then read what i said about bromine in soft drinks?
19:36 katsmeow-afk it's worrysome that softdrink oem can put a chemical into a drink at such a level, it's proven and shown that if two 2-liters are drunk each day it's neurotoxic and potentially fatal, requiring hospitalisation
22:38 rue_house I did, I'll avoid those ones thanks
22:51 katsmeow-afk now is the time to catch seasonal closeouts of lawn pools, 10ft x 30inch for $70, holds 1000 gallons, is not bear or cat claw proofed
23:04 katsmeow-afk if that lil wellhole you dug can deliver 0.7 gallons per minute, you can completely refill the 1000 gallons every day
23:06 katsmeow-afk just one liter per minute will deliver 375 gallons per day
