09:00 rue_house did you see the one for the teddybear that was supposed to be fully ai?
09:00 rue_house and sentient?
13:26 katsmeow-afk i cannot figure how the bearing as shown on the shaft in the hole i bored ini the oem end bell is correct, per the pics, and is the same place on the shaft as at the end of the page, yet the dimensions are off in the sketch
13:38 katsmeow-afk [13:23] <katsmeow-afk> last nite i worked out a seriously cheap way to add 100psi hydraulics to a mobile platform, which may not sound like a lot, but cheap 3" pvc pipe will 100psi in it will push a piston at 700lbs force

15:53 katsmeow-afk someone got theirlistings screwed up
16:03 katsmeow-afk either way, they are all prolly vintage 1998, 14 yrs old, used or not
16:08 tsmeow-afk tries again to push a chain over a spro
16:51 katsmeow-afk awe crap, i said i wouldn't post ebay prices again
16:51 tsmeow-afk slams a door on her paw in atone
17:32 katsmeow-afk http://abcnews.go.com/Technology/slideshow/spaceship-design-apple-campus-20863523
17:48 tsmeow-afk taps Tom on his shoulder for his opinion on cutting holes in http://i.ebayimg.com/t/1-4-inch-hole-9-X-12-inch-piece-Stainless-Steel-Perforated-304-20-gauge-/00/s/MTA2NlgxNjAw/$T2eC16JHJHgE9n0yE%284%28BQNnQYIhh!~~60_57.JPG to insert these led readouts http://designerthinking.com/images/Tek-design/DSCF6477m.jpg
17:49 Tom_itx laser
17:50 katsmeow-afk being the module is ~5" x 2.5", and handles 500 watts, dissipating ~40 watts internally, airflow is an issue, so if i draw air str8 into the front panel, past the leds, over the heatsinks, and then back over the rest of the circuits and out the back, it would help
17:51 katsmeow-afk laser? i have no laser. why not just a zip disk?
17:51 Tom_itx the hole edges are all rounded
17:52 katsmeow-afk the holes are ~ .5"x.5" and .75"x.5" square
17:52 Tom_itx yeah slot it with a grinder
17:52 katsmeow-afk oh, the round holes are already there
17:53 katsmeow-afk behind the led-pcbs, i can put colored led liting up the heatsinks, a 3D effect, a practical airflow
17:59 katsmeow-afk is 1/4 holes going to look ok?
17:59 katsmeow-afk http://stores.ebay.com/Consolidated-Mill-Supplies-LLC/Perforated-Stainless-Steel-/_i.html
18:01 Tom_itx you ordering or already have?
18:01 katsmeow-afk will order
18:01 katsmeow-afk got ideas?
18:01 Tom_itx i might use 1/8" finer stuff could get sucked thru it
18:02 katsmeow-afk dust will get in it anyhow, i wasn't going to add a filter, need the airflow
18:02 Tom_itx should be fine then
18:03 katsmeow-afk pop the module out, blow compressed air as needed, or keep it in a glass-front 19" rack cabinet
18:05 katsmeow-afk is 20 guage too thin to be structural?
18:05 katsmeow-afk it's stainless, but still that's thin
18:05 Tom_itx no idea
18:06 Tom_itx probably ok, not sure what 20ga 'feels' like
18:06 katsmeow-afk http://www.ebay.com/itm/Perforated-304-Stainless-Steel-1-32inch-hole-24-gauge-Price-per-8-square-inches-/130701086245 ?
18:06 katsmeow-afk ouch, no that's real thin
18:06 katsmeow-afk 24 guage normal steel will barely hold itself up
18:06 Tom_itx maybe gettin free electronics
18:06 katsmeow-afk hmm?
18:08 Tom_itx http://store.mesanet.com/index.php?route=product/product&path=69_70&product_id=123
18:09 Tom_itx linuxcnc had a week long fest here recently and i was promised one but never got it (somebody else made off with it)
18:09 Tom_itx so he's checking to see if they have an 'open' package they can send
18:09 katsmeow-afk one card?
18:10 Tom_itx not sure, maybe a couple
18:10 katsmeow-afk free is free, but i bet you could make that card for $15
18:10 Tom_itx i use their boards on my mill
18:11 katsmeow-afk aah, better deal then
18:19 katsmeow-afk cop shot a dog coming at him aggressively, owner says "my dog would never do that" , but the owner wasn't there, and the dog was not on the owner's property
18:19 katsmeow-afk same ole same ole
18:20 Tom_itx i had to modify the driver for one of my exhisting boards to drive this one
18:20 Tom_itx xininx
18:20 Tom_itx but i think that's all done, just haven't been able to test it
18:21 Tom_itx no funds to purchase one so i've just been sitting waiting
18:22 tsmeow-afk
18:23 Tom_itx sserial
18:23 Tom_itx not sure what the 's' stands for
18:23 Tom_itx but it sure gives you alot of io
18:23 katsmeow-afk my favorite prices are "free" and "scrap" too
18:24 katsmeow-afk 2nd fav are "deep discount" and "sale"
18:24 Tom_itx those are more 'come-ons' to get you in the door
18:25 katsmeow-afk maybe, but i seldom pay full regular price
18:25 katsmeow-afk in a pinch, i will, but if i can wait, i will
18:26 Tom_itx http://thread.gmane.org/gmane.linux.distributions.emc.user/42692/focus=42699
18:26 Tom_itx pretty cool place
18:26 katsmeow-afk i'd rather buy 4 band saw blades on sale than drive back 4 times for a blade at regular price each time i need one
18:26 tsmeow-afk is useless with *nix
18:27 katsmeow-afk i know a Mark Wendt from anotehr listserv tho
18:27 Tom_itx live cd install takes all the effort outta it
18:27 Tom_itx it was cool that they came from all over the globe and it was right in my back yard
18:27 Tom_itx about 3-4 mi from the house
18:28 katsmeow-afk cool
18:28 Tom_itx helped a few find hotels
18:29 katsmeow-afk heh, cop challenged another motorcylce rider to race while on duty, lost his job, the other rider had video'd it all
18:30 Tom_itx gonna go nurse a headache a while
18:30 tsmeow-afk hands Tom an oj and ,,,, something alcoh
18:31 katsmeow-afk this Canadian air is *super* dry atm, try a humidifier
18:36 tsmeow-afk decides the best bet is prolly to just do a good job with the crimping, then solder, and keep a fan on it to keep the solder from mel
18:37 katsmeow-afk heh, there's a good job for stainless steel perforated sheet? bolt every hole on opposite sides to buss bars, aim fan thru the holes, call the ss sheet "whopping big power resistor in small space"
18:38 katsmeow-afk fwiw, stainless welding wire works too
18:38 katsmeow-afk so do recycled central air hearer assy's
18:39 katsmeow-afk heater
18:39 tsmeow-afk tested a 140vdc 5amp psu that
18:41 katsmeow-afk need to throw away 100kw? use the fence strung around the cow/horse pasture
18:42 katsmeow-afk iirc, i figured once that 40ft of 2" steel pipe, water flowing thru it and over it, would hold up to 208vac across it, depending on water flow rate and pipe wall thickness
18:43 katsmeow-afk i gotta stay off my feets tonite, been on them too much, got leg cramps all day today
18:44 katsmeow-afk naturally, i'll prolly ignore myself :-/
20:28 rue_house lola?
20:29 Tom_itx if you showed join and part you would realize...
20:31 rue_house I was just at her place, I know she's loggin into somewhere
20:35 Tom_itx * Lola8088 has quit IRC (Ping timeout: 246 seconds)
20:35 Tom_itx * Lolina8088 has quit IRC (Client Quit)
21:32 katsmeow-afk Lola8088 has been idle 8mins 31secs Signed on 11/13/13
22:00 lina8088 pokes
23:03 rue_house there you are
23:03 katsmeow-afk YES!!
23:03 rue_house bill is annoyed, I apparently ate both parts of the supper he cooked for us
23:03 rue_house so I putmore spagetti on
23:03 katsmeow-afk sorry i missed that
23:03 rue_house welcome back to the internet
23:03 katsmeow-afk thanks! :-)
23:04 rue_house kat, could you please show me a collection of finger deign drawings you done?
23:04 katsmeow-afk i didn't draw anything
23:04 rue_house ? im sure you had design drawings for robotic fingers
23:05 katsmeow-afk there are some online not by me, but the steel finger i built is all in my lil head
23:05 rue_house oh
23:05 katsmeow-afk heck, i have laid out video switchers on pcb in my head, single-sided pcb even
23:05 katsmeow-afk it's real cluttered in my head
23:06 katsmeow-afk which is why it bugs me how both sketches ON PAPER of the motor are ~.90 off
23:08 katsmeow-afk why did you want sketches?
23:09 tsmeow-afk put pics online, and you know the dims on
23:11 katsmeow-afk the "bones" are all keystock
23:12 katsmeow-afk the ball bearings are the cheapest (this is proof of concept) i could find on ebay, the good bearings this size have 2x as many balls and have seals
23:13 katsmeow-afk the most important part of the drilling is *always* drill undersized, but as close as possible, then ream to finished size
23:13 katsmeow-afk because these bearings have zero self-support in their races
23:14 katsmeow-afk and, leave as much steel as possible in the bearing areas
23:14 katsmeow-afk you see in DesignerThinking.com/images/fingers/DSCF3062m.jpg that i did not drill the bearing OD all the way thru
23:17 katsmeow-afk http://designerthinking.com/fingers.html
23:19 katsmeow-afk and you note i am not in #robotics
23:51 katsmeow-afk hmm, in the calc.exe on winxp, in bin mode, if i enter 1111 1110 - 1111 1111 , the answer, in dec mode, is 18446744073709551615
23:53 tsmeow-afk has been pondering a puter system where everything is treated like a memory location in 2^48 space, including variables (in ram and on hdd) and files (in ram and on hdd),, each item would have a 48bit addy and a 48bit length, and all look the same to the

23:55 rue_house http://DesignerThinking.com/images/fingers/DSCF3062m.jpg
23:55 katsmeow-afk hmm?
23:56 rue_house ^^ clickable version
23:56 katsmeow-afk you need a larger pic?
23:56 rue_house no
23:57 katsmeow-afk i dunno what you are trying to tell me
23:57 rue_house nothing
23:57 katsmeow-afk ah, then you have succeeded, i have been told nothing
23:57 rue_house I'm merely transforming the world to operate within my understanding
23:58 katsmeow-afk if the page should operate differently than it is, i may perform your suggestions to improve it
23:58 rue_house havn't you heard? "a man hears what he wants to hear and disregards the rest" I think is how simon and garfunkle put it...
23:58 katsmeow-afk but i am not a man :-P
23:59 rue_house the page operates fine, my irc client requires http:// to understand its a link so I can click it
23:59 katsmeow-afk oh!
23:59 rue_house and irc makes a great loggin 1 line edit buffer
