00:09 katsmeow-afk "An RO unit deliver-ing 5 gallons of treated water per day may discharge 40 to 90 gallons of waste water per day to the septic system.
00:09 katsmeow-afk " ??
00:23 tsmeow-afk would consider that unacceptable and use it to flush
00:24 katsmeow-afk or water the yard
00:24 katsmeow-afk etc
01:20 rue_mohr RO?
01:21 rue_mohr ah, it must be a filter, thats able to produce 5 gallons of fresh water for every 40 to 90 that goes out as contaminents
01:23 rue_mohr well back to work
01:23 rue_mohr monday is gonna be long too, I start a job at 5pm
01:33 katsmeow-afk ro = reverse osmosis
01:34 katsmeow-afk alledgedly filters contaminates down to .001
01:34 katsmeow-afk meaning it filters out large molecules and all viruses and cysts and things
01:35 katsmeow-afk but they are eitehr self-washing, dumping 3x to 10x as waste continually, or they need shutdown and powered backflushing, or they stop up pretty fast
01:36 katsmeow-afk 5 out and 90 waste seems like an awefully bad ratio tho
01:36 katsmeow-afk that's 1:18
01:37 katsmeow-afk gnites
01:38 furrywolf you can get a much better ratio with a pressure pump on the inlet
01:38 furrywolf you can either use an electric pump to boost it to 100psi, or a permeate pump that recovers the energy in the outlet water and uses it to increase the pressure of the inlet water.
01:40 furrywolf I think I read you can get to a 1:1 treated:waste ratio with suitable pumps.
01:40 rrywolf curls up on katsmeow-afk for bed
02:13 furrywolf oh, and there's ones that use the energy in the waste water to create a vacuum on the outlet water, again increasing the pressure differential.
02:14 furrywolf bbl.
05:28 katsmeow-afk Memphis Tn could get hit hard : http://www.wunderground.com/radar/radblast.asp?ID=NQA
05:33 katsmeow-afk wow @ http://xkcd.com/1052/
05:42 katsmeow-afk wow @ where the Missississississississippi river is now, compared to where it was when the state lines were drawn on it : http://maps.google.com/?ll=35.178298,-90.068665&spn=1.055121,1.60675&t=m&z=9
06:21 katsmeow-afk someone should call and warn Nashville http://www.wunderground.com/radar/radblast.asp?ID=NQA
06:21 katsmeow-afk er, Memphis
09:11 sw0rdfish hmmmm.
11:08 katsmeow-afk furrywolf, it's nuts how many places do not sell everything needed for the so-called systems they sell, and i am not talking about options like the permiate pumps
11:09 katsmeow-afk one place sells only filters, one sells fittings, but no housings
11:09 katsmeow-afk one sells filters and housings, but no fittings
11:10 katsmeow-afk one sells filters and housings and fittings, but no check valves or tubing or restrictors
11:10 katsmeow-afk one sells faucets and housings and filters, and nothing else
11:11 katsmeow-afk many sell filters, and no housings, very few sell tanks
11:11 katsmeow-afk none sell or suggest how to put together a system
11:12 Tom_itx sent
11:12 katsmeow-afk one got back to me with "yes, i have one of those for sale in my store", but no part number or anything,,,,, i felt like emailing him back "cool, i have money in my checking for it", but not buying it from him
11:13 katsmeow-afk frankly, i emails him because i couldn't find it in his store, him saying it was there, and not giving a part number, is like saying he can't find it either
11:13 katsmeow-afk thanks, tom
11:14 tsmeow-afk couldn't sleep most of the
11:14 katsmeow-afk err, you should be at work?
11:14 Tom_itx yes i should
11:14 tsmeow-afk offers a toast to "w
11:15 katsmeow-afk whole wheat toast
11:15 Tom_itx afk
11:16 sw0rdfish anyone know of a good OCR course
11:16 sw0rdfish or any resource.
11:16 katsmeow-afk i was also wondery, can one look at a servo and tell how long it will last in some given situation
11:19 katsmeow-afk sw0rdfish, i read a bit about it in the 1990's, when it wasn't so good, and everyone was trying to make it better, before the 1990's it was not even a guessing game about ocr'ing typed text
11:20 sw0rdfish oh.
11:20 katsmeow-afk the bad ocr of the 1980's is why we have barcodes now
11:20 katsmeow-afk it simply didn't improve enough thru the early 1990's, so computer/laser barcoding took off
11:21 katsmeow-afk the late 1990's, it got pretty good if youtrained your system on a particular font
11:22 katsmeow-afk it all still required proofreading, spellchecking was absolutely mandatory
11:22 katsmeow-afk after 2000, i lost track of it all, specially since i wore out my flatbed scanner, sorry
11:47 sw0rdfish I see. :)
11:47 sw0rdfish cool d:
11:48 sw0rdfish well get into it again katsmeow-afk :)
12:20 SolarNRG Hi guys
12:20 SolarNRG I went for a very long walk today
12:20 SolarNRG Everywhere was shut,
12:20 SolarNRG Bank holiday
12:20 SolarNRG And
12:20 SolarNRG I could not find any old discarded cookers
12:20 SolarNRG :(
12:21 Steffanx Poor you
12:23 SolarNRG And I'm feeling rubbish
12:26 Steffanx Poor you
12:29 SolarNRG How are you?
13:21 furrywolf katsmeow-afk: do you already have most of an RO system and are trying to find the missing bits, or are you trying to assemble a complete system from scratch? buying a complete unit works out to be a lot cheaper than buying individual parts, I found.
14:14 katsmeow-afk furry, i did not know that, plus i wanted a segmented system, so, i have unfiltered to outside faucets, then i have a 20u filter, then a tap to the toilet flush, then a 0.5u filter and a tap to sinks and showers, then a stub for the RO filter to goto dedicated faucets at sinks
14:15 katsmeow-afk gotta go get pump fittings, bbl
14:22 IndianaRonaldo_ which controller best for making quadrotor?
14:25 Tom_itx avr atmega328
14:27 IndianaRonaldo_ I haven't started. I'm a bit hesitant about the total cost involved. Can you gimme an estimate ( rotors,controller,jtag) ?
14:27 Steffanx Ha other KongfuPanda_
14:28 KongfuPanda Hi Steffanx
14:58 Tom_itx you don't need jtag
14:59 Tom_itx someone in here or in #avr did a quadcopter, you might ask around
15:32 IndianaRonaldo hey thanks, Tom_itx. Will try that
15:57 IndianaRonaldo a
16:36 katsmeow-afk fast mving storm, Bham is getting what Memphis got earlier : http://classic.wunderground.com/radar/radblast.asp?ID=BMX
16:39 Steffanx katsmeow-afk has a nice basement like tom?
16:39 katsmeow-afk nope, it's unfinished, because the DA's office said i haveto allow rottwiler dogs in to bite me
16:40 katsmeow-afk and it's actually a cellar, really, one side is at ground level, 3 sides are buried
16:40 katsmeow-afk house sits on top
16:41 Steffanx I don't know the difference :P
16:41 katsmeow-afk i think maybe it boils down to Tom calls his a basement and all sides are underground, i call mine a cellar and one side is not buried
16:42 Steffanx I think we only have one word for that in dutch
16:44 katsmeow-afk in my wild imagination, i think it's because Tom's house relies on his basement to hold the house up, but in my construction the house was build before the space below it was enclosed,, it's not really the base structure of my house
16:45 katsmeow-afk and in the phrase "root cellar", those were not always build under a house, they could be built into a nearby hillside, with a section of wall and a door exposed, so not entirely buried
16:46 katsmeow-afk the concrete shell of my house sits around the space under the house, which was a stand-alone proper structure before
16:47 katsmeow-afk pics at http://designerthinking.com/house.html
16:48 Steffanx Nice wall structure
16:49 katsmeow-afk double offset stud, steel embedded, double insulated, sheathed,,,,,, and that's just the wooden part
16:51 katsmeow-afk i need to convert that page to css also
16:55 Steffanx Noo, tables are great katsmeow-afk
16:55 Steffanx Anyway, gn
16:56 katsmeow-afk gn
17:19 katsmeow-afk significant lightning atm, i am surprised the internets are still up, and power on
19:40 katsmeow-afk that was the loudest i have ever heard a lightning strike inside, and that includes the time it hit the house and blew every lightbulb, kicked every breaker, and vaporised my telephone line
19:41 katsmeow-afk and split the tree ouside from top to roots
19:45 Tom_itx guess you know where it hit then
19:46 katsmeow-afk that one, yeas, the one tonight, no
19:46 katsmeow-afk i have been looking for damage, haven't found anything yet
19:46 Tom_itx oh
19:47 katsmeow-afk the trees and grass seriously got to being green after this storm, it's amazingly green, neon green even
19:47 dunz0r I wouldn't mind a thunderstorm now. It's really nice to watch at night.
19:49 katsmeow-afk there's a small severe storm running east on I-20 to Atl right now, near the Al-Ga border, but it might fail as the sun goes down
19:49 orlok Its been cloudy and raining on and off here for the past few weeks
19:49 katsmeow-afk south Ark is being badly hammered, Nawleans might be spared
19:49 orlok today is the first time the sky is visible
19:50 orlok .. i keep putting off finishing my code
19:50 zhanx its cloudy and raining here
19:50 orlok "Its not important, its cloudy!"
19:50 zhanx i finished more of my code today
19:50 zhanx need to build my pedals now
19:50 katsmeow-afk Macon Ga, all that mil base there, is gonna get some weather
19:50 orlok i just need to implement a few commands for the guiding
19:51 katsmeow-afk poor Ill and N Oh got wrung out today
19:51 zhanx not here it was sunny for once and my boss is gone
19:51 orlok amerlia started crawling on sunday
19:51 orlok amelia
19:51 katsmeow-afk yay for bosses being gone!
19:51 zhanx his wife had twins friday
19:51 zhanx so i am the boss for 30 days
19:51 orlok proper crawling, up until now she has been commando crawling
19:52 katsmeow-afk poor twins and wife
19:52 zhanx commando is the best
19:52 katsmeow-afk heh@ commando crawling
19:52 zhanx and yes my boss is a dick
19:52 zhanx everyone loves me in charge
19:52 zhanx i am not the yelling type
19:52 zhanx i use words to make you feel bad
19:53 katsmeow-afk i would say south-central Tx is getting weather, but i can't find it
19:54 katsmeow-afk it's something of a change, Tom has been getting it so ofetn, but not today
19:55 zhanx i mostly finished the garden today
19:55 zhanx rain is good
19:55 katsmeow-afk that 15ft dia pool with 2ft of water in it looks soooooo inviting, but it's ice cold
19:56 zhanx darn
19:56 katsmeow-afk i did plumbing today, not ready to turn pump on yet
19:56 zhanx but soon!
19:56 katsmeow-afk tomorrow, weather permitting
19:56 zhanx cool
19:57 katsmeow-afk the pump won't be in my first or 2nd choice spots, but it will be ok i expect
19:57 zhanx tomorrow is the army ceremony for my soldier
19:57 katsmeow-afk at least till freezing sets in
19:58 katsmeow-afk what happens to the tease who screwed with his head?
19:58 zhanx still in jailm couldn't post bail
19:58 katsmeow-afk good
19:58 katsmeow-afk what charges?
19:58 zhanx and its gone from suicide to homicide
19:58 katsmeow-afk fraud? decit?
19:59 zhanx his finger print wasn't on the trigger
19:59 katsmeow-afk told ya
19:59 zhanx since her bail is like 250 thousand i am thinking its hers
20:00 katsmeow-afk they would have found out by now, if it was print evidence
20:00 zhanx i was directed to give him full honors the day she was arrested
20:00 katsmeow-afk well, that's something
20:00 zhanx that night my battalion commander flew down to present the flag to the mother, something that doesn't happen with suicides
20:01 tsmeow-afk
20:01 zhanx either way i am now out of the loop its higher than me
20:01 tsmeow-afk nods some
20:02 zhanx plus they are flying the family here tomorrow for the ceremony. again something they don't do with suicides
20:02 zhanx but as his squad leader i won't find out for a while what happened
20:03 katsmeow-afk well, at least something IS happening
20:04 zhanx this is true
20:04 zhanx the bonus, my soldier who had this happen in his house doesn't have to pay for clean up
20:05 katsmeow-afk being that he won't get another paycheck, i wouldn't think he would pay for it anyhow?
20:06 zhanx no, he did this in one of my other soldiers house, he was spending the night to go fishing with me in the morning
20:06 katsmeow-afk oh, ok, i got the pronouns mixed
20:06 zhanx so the fishing trip we had planned for last sat will be this sat
20:07 zhanx i was suppose to take 9 soldiers out trout fishing
20:07 zhanx now i am taking 8
20:07 katsmeow-afk don't get drunk and get hurt out there
20:07 zhanx nope
20:07 zhanx its an authorized day off from work now
20:12 katsmeow-afk ok, dark, i need to go close doors and things, ben airing out the house, bbiaf
20:26 katsmeow-afk smells nice out there, it would be a great nite to sleep on the roof, if i could, which i had planned on being able to do with this house
20:49 furrywolf why can't you?
20:53 katsmeow-afk it's merely a roof, thin elasomer over somewhat hardened tar
20:53 katsmeow-afk plans called for it to have a walk-about deck suspended above the elasomer
20:54 katsmeow-afk i wanted to do things up there, there's running water and the powerline is terminated just inside, and the elevator was to go up there (it's guide rails do)
20:55 katsmeow-afk if i had a telescope, i'd be up there now, there's two interesting lights in the sky atm
20:56 katsmeow-afk i wanted to run xmas tree lites around under the roof eaves up there (~4ft above the deck position), white and cobalt blue lites
20:56 katsmeow-afk i got the 7w bulbs before they were discontinued
20:56 furrywolf heh, for lighting?
20:56 katsmeow-afk mood lighting, yeas
20:57 tsmeow-afk throws an url out for all newbies to read completely : http://en.wikibooks.org/wiki/Category:Electronics_%28book%29
20:58 orlok Saturn is to the SE 35 degrees up, next to SPica, and Mars is SSW, about 65deg, next to Regulus
20:58 katsmeow-afk ( at least as a section pertains to robots )
20:58 orlok Venus is 20deg up about 20 degrees north of west
20:59 orlok katsmeow-afk: that line up with what you saw?
20:59 katsmeow-afk maybe that's one of the lite, it's intensely bright
20:59 katsmeow-afk yeas, it is
20:59 orlok Saturn, Mars will be reddish
21:00 orlok unless its Venus, that will be quite low
21:00 orlok mars quite high
21:00 katsmeow-afk there's a dim blinkely lite, periodically looks red, just west of south of me
21:00 orlok low on the horizon?
21:00 orlok oh, thats mars
21:01 katsmeow-afk i never understood that term, but it's lower than the lite to the north of west
21:01 katsmeow-afk it's maybe 30 degrees up from horizontal
21:04 orlok Mars should be higher..
21:04 orlok Betelgeuse is red and directly west
21:05 orlok but quite low
21:06 katsmeow-afk it might be higher, it's hard to tell, on the roof i am over 30ft off the ground, and the mountian slopes away from me drastically, and there's a large valley to my south and west
21:06 orlok yup
21:06 katsmeow-afk i'd haveto use a level to know level up there
21:07 orlok i have bene known to sight along a compass heh

21:11 furrywolf it's a good thing we all have access to your hard drive, so we can see those.

21:11 orlok furrywolf: trivial tweak to the URL..
21:11 katsmeow-afk yeas, delete the "file:///C:/my%20domains/"

21:16 katsmeow-afk when the dogs were given all the rights to my place, i lost a lot
21:25 tsmeow-afk told tiggr to grab that wikibooks page
22:12 katsmeow-afk ...
22:16 katsmeow-afk humans have a bttomless pit of ways to surprise me:
22:16 katsmeow-afk May 7, 2012 -
22:16 katsmeow-afk The dried flesh of dead infants appears to be the not-so-secret ingredient in a health supplement that is reportedly being smuggled out of China.
22:16 katsmeow-afk The performance-enhancement pills, touted for increasing vitality and sex drive, have been found in the luggage of tourists and in international mail, according to South Korean authorities.
22:17 katsmeow-afk They said they had confiscated nearly 17,500 of the human flesh capsules since last August
22:17 katsmeow-afk Last year, the South Korean television station SBS aired a documentary that accused Chinese drug companies of collaborating with abortion clinics to produce the pills from dead fetuses.
22:17 katsmeow-afk The documentary claimed that DNA tests verified that the pills were made from powdered humans.
22:37 furrywolf have you seen the articles on fake eggs? :)
22:39 katsmeow-afk no
22:40 furrywolf http://www.chengduliving.com/fake-eggs-are-no-joke/
22:40 furrywolf I'm not convinced it's not all a giant hoax, of course. :)
22:43 katsmeow-afk i recall years ago there was an attempt tomake fake eggs in the usa, to eliminate cholesterol and something else from real eggs, othrwise they were supposed to be identical materials, mostly, but i think there was no market for them
22:44 furrywolf oh, speaking of china, did you see the fake transformers? http://www.hardwaresecrets.com/blog/Hantol-PSU-Fake-PFC-Made-of-Cement/220 http://www.pcpop.com/doc/0/294/294565_all.shtml
22:44 furrywolf nothing from china surprises me anymore. heh.
22:46 katsmeow-afk http://www.hardwaresecrets.com/blog/Hantol-PSU-Fake-PFC-Made-of-Cement/220 <<== resets and dies
22:46 furrywolf ?
22:46 furrywolf look at the second link too. heh.
22:47 katsmeow-afk http://www.pcpop.com/doc/0/294/294565_all.shtml <<== all chinese
22:48 furrywolf look at the pictures. heh.
22:49 katsmeow-afk Tom's Hardware did an article on badly over rated pc psus, made by Sparkle,a nd others, and i had just ordered some off ebay, i checked them out and what was shipped wasn't even what i ordered, i told ebay, they refunded every penny of purchase and s&h
22:49 furrywolf sparkle is rebranded deer
22:49 katsmeow-afk deer?
22:50 orlok haha wow
22:50 orlok i used to go by "heavier is better" too
22:51 furrywolf the best part is every one they took apart is a completely different design, so there's at least six companies making fake transformers.
23:15 katsmeow-afk i wonder if it's a language barrier .. "i want them to look just like this"
23:17 katsmeow-afk i heard a story long time ago, in 1950's a usa company was outsourcing to Japan, and repeatedly stressed they wanted quality as good as 3% defects across all possible defects, and that's what was delivered, every shipment was 3% defects
23:18 katsmeow-afk the factory was making product with zero defects, then pulling 3% off and sending to a defect insertion line, they broke them, reassembled them, and placed randomly in the outgoing shipment
23:19 katsmeow-afk the japanese company didn't understand whyt he americans wanted it this way, but since they paid for it, they got it
23:21 orlok heh
23:21 orlok nah, i'm sure it was done for profit reasons
23:21 orlok the fake PFC unit that is
23:22 katsmeow-afk http://fmylife.tumblr.com/
23:23 furrywolf yay! someone on craigslist might want to buy my spare inverter.
23:23 katsmeow-afk LOL : Today, I tried opening a can for the first time using a manual can opener. I tried for a half hour to open a can of ravioli, mutilating the can in the process. Only after watching five Youtube videos on how to use a manual can opener did I notice the pull-tab on the top of the ravioli can. FML
23:23 rrywolf needs
23:24 katsmeow-afk Today, there was an animal rummaging around in my trashcan, so I kicked the trashcan to see what it was. The fox then chased me for three blocks to find out what I was. FML
23:39 katsmeow-afk ...
23:55 furrywolf if I sell my inverter, I'll have enough cash to buy the used, broken batteries I want to add to my solar system.
23:57 dunz0r furrywolf: But why buy used, broken batteries? Surely your inverter can't be that cheap?
23:57 dunz0r Or your batteries that expensive.
23:57 furrywolf the latter.
23:58 furrywolf it's a set of 40 Kursk ni-fe cells, that need the electrolyte replaced.
23:58 dunz0r Ah.
