03:12 rue_shop3 seems its still 60 degrees
03:12 rue_shop3 cool
03:12 rue_shop3 now, how DEEP is the thead...
05:11 rue_shop3 .35mm
05:11 rue_shop3 I love how on the final threading pass, although the bit is ligned up right, it tears almost all the thread off
05:12 rue_shop3 well I did it, I made a plotter pen
05:12 rue_shop3 one of the drafting style ones
05:41 rue_shop3 http://patentimages.storage.googleapis.com/pages/US3535048-0.png
05:41 rue_shop3 one of those
05:42 rue_shop3 but I didn't know the tip is supposed to be cut at an angle
14:24 katsmeow-afk you made a pen with an internal self-cleaning feed tube?
14:25 tsmeow-afk hands rue one of her mechanical pen
14:34 rue_bed It think I did, but the weight seems to play a double roll in blocking off ink flow when the pen is up
14:53 katsmeow-afk you want the pen to dribble ink when it's up off the paper?
14:54 tsmeow-afk hands rue a party balloon like they twist to make animal figures with, to put ink into, put into a barrle, and pressurise the barrel, to force ink out the en
15:03 katsmeow-afk "to use this pen properly, you will need a source of clean 150psi air pressure......"
15:05 katsmeow-afk if it's going into a machine, i'd just use something like a fuel injector, the kind with the pump inthe injector, to meter the exact *qty* of ink needed, vs the flow or pressure of the ink
15:05 katsmeow-afk of course, if you use 10 of them in one print head, you'd have a dot matrix printer
15:11 katsmeow-afk here irl, they are advertising a "robot" parrot on tv, they cut the head off a blow-mold parrot, put ina servo to turn it tot he right and back 30 degrees, make a noise, and move "tail feather" 10 degrees,,, and they show humans with exhibitions of affection for the device, because it needs no dailey food or excrement pan cleanup
15:13 katsmeow-afk SeaTac Wash businesses are facing 60% min wage hikes, so they are going to fire 60% of human employees because they cannot hire robots who work for free
15:14 katsmeow-afk one resturant chain says they will simply transfer all employees they wanna get rid of to two particular resturants, then close them

15:24 katsmeow-afk wwoooahhh : http://weburbanist.com/2009/12/08/snow-sculptures/
15:40 rue_house hmm
15:48 rue_house wow, the world is creative
15:49 rue_house ok, it seems that everything major I did to my computer latley was done before the ssd was put in, so I still have everything on the old drive
16:01 rue_house kat kat kat I got the converter baords for my power supply
16:27 katsmeow-afk kool kool kool!
16:28 katsmeow-afk prease keep in mind, running them for more than 20 sec above 2/3 rating will require forced cooling : fan and prolly additional heatsinks
16:29 katsmeow-afk these 5a@15v die at 5amps, and to get 4amp continuous requre removing them from enclosure and appliyng lots of moving air over them, and they are switchers too
16:31 katsmeow-afk Wall Street Journal - ?26 minutes ago?
16:31 katsmeow-afk
16:31 katsmeow-afk
16:31 katsmeow-afk
16:31 katsmeow-afk Aviation officials on Monday selected a handful of universities and state agencies to operate sites for drone testing, in a step toward eventually integrating commercial unmanned aircraft into the U.S.
16:35 katsmeow-afk Titusville, Vero Beach and Fort Pierce showed that it got that cold several times in the 1980s. But the last bitter freeze in central Florida occurred in 1989, and cold sufficient to kill off mangrove seedlings has not occurred at all in recent years.
16:40 tsmeow-afk ponders putting it all in a small sealed tub of oil, a cheap pump and huge radiator somewhere else,,, this will keep the parts cool, keep the magic smoke from getting into the room when it leaks, and prevent the particles of the explosions from getting into other s
16:47 rue_shop3 I only plan to get 2A from them
16:47 katsmeow-afk o
16:47 rue_shop3 which is 200% my current supply
16:48 katsmeow-afk no it isn't, you are getting that $30 16amp supply, arent you?
16:49 rue_house its a 10A supply, I dont expect to get more than 5A from it
16:49 rue_house :) I'v accounted some for china here
16:49 katsmeow-afk k
16:50 rue_house I just hope its all good for 30V
16:50 tsmeow-afk
16:51 katsmeow-afk you check the cap ratings? "0-30v output" with 25v caps isn't going to work
16:51 rue_house 35V
16:52 katsmeow-afk k
16:53 katsmeow-afk my Sansui has 45v caps in the psu, which is fine when it's fed 110vac from the line, but with 125v from the line the psu is over 50v
16:53 katsmeow-afk the Marantz works great at 110vac, but blows up at 125vac in
16:53 rue_house but they are prolly old capts that are 150%-200% capable
16:54 katsmeow-afk yeas, so far, but it's asking for trouble to use them
16:54 rue_house old days the stamp wasn't the abs max! :)
16:54 rue_house these days I think your lucky if the stamped isn't 110% what it can take
16:55 katsmeow-afk my old heavy battery charger works fine at 120vac, 20amps out easy, but won't put out more than a couple amps at 110vac and a 100ft extension cord out to the car
16:55 rue_house well I'm gonna give this power module a run
16:56 rue_house I'm still waiting for the 10k pots to come in, then I think I can start building it
16:56 katsmeow-afk "if you hear celebratory gunfire, call the police" ,, "sorry, i thought he was murdering his neighnors, i didn't know it was celebratory" ,, "it mostly wasn't, but the last two shots were, and you should have called!" ,, "i didn't know!"
16:57 rue_house hmm
16:57 rue_house newyears gets rambunctious?
16:58 katsmeow-afk yeas, like hunting season
16:58 katsmeow-afk humans shoot off clip after clip of various ammo, other humans invariable get punctured, some of the hhumans become non-functional
17:07 katsmeow-afk iirc, a few yrs ago, some guy went out and stepped off his covered porch and shot straight up, then stepped back under the porch roof, the bullet came back down thru the roof and into his shoulder
17:09 katsmeow-afk makes me wonder why they don't use less energetic powder loads, and cotton swabs instead of lead for bullets, like .22 ratshot, which won't penetrate the top layer of wood on cheap osb
17:09 rue_house it started to stress out after 4A
17:09 rue_house but did pretty good
17:10 rue_house I think the core could use larger wire
17:10 tsmeow-afk
17:10 katsmeow-afk better the magnetics get hot than the caps tho
17:11 rue_house the magnetics and the switcher started to heat up sharply
17:11 rue_house might have been saturation come to think of it
17:11 katsmeow-afk i found on these, the transformer stays hot and benefits the most from constant air over, while the minimal heatsink on the semiconductors will cool them off pretty fast with very little air, the caps run lots cooler with air on too
17:12 rue_house I got my 50pcs lm7805 :)
17:12 rue_house $6
17:12 katsmeow-afk i suspect the transformers are designed to saturate at the max output voltage
17:13 katsmeow-afk good price
17:14 katsmeow-afk i figure at full load the switcher absolutly cannot push the transformer any harder, it simply makes more heat instead of more output
17:14 rue_house http://www.aliexpress.com/snapshot/303188582.html
17:16 katsmeow-afk just for giggles, and maybe to verify they are the correct part, it's cheap insurance to verify the outpu with a dvm before hooking up to anything
17:16 Tom_itx is that like a chinese walmart for geek stuff?
17:16 rue_house still waiting for my lugs, and the 74ls00
17:16 rue_house Tom_itx, its new wholesale parts from china
17:16 Tom_itx i know
17:16 Tom_itx i've had it bookmarked for some time
17:16 rue_house prices go up sharp for small qualtities tho
17:17 katsmeow-afk how do you pay for the parts in alibabba?
17:17 rue_house I been getting lifetime supplies of some things
17:17 katsmeow-afk or aliexpress
17:17 Tom_itx paypal?
17:17 katsmeow-afk i dunno
17:17 rue_house katsmeow-afk, credit card direct, the site holds the money in escrow till the buyer has accepted the package
17:17 katsmeow-afk o
17:17 rue_house which means you get your package or your money back
17:18 rue_house waaaaay better than ebays thing
17:18 Tom_itx except they get your cc info
17:18 katsmeow-afk yeas
17:18 rue_house bah, credit card compaies will take care of any disputes there
17:18 katsmeow-afk they don't for me
17:19 rue_house o
17:19 katsmeow-afk "you paid, they took the money, we are done, so you didn't get the stuff, sorry, talk to seller, have a nice day" <click>
17:19 rue_house so far 'v has 100% success with alibaba
17:20 katsmeow-afk 'v ?
17:20 katsmeow-afk oh
17:20 rue_house katsmeow-afk, yea, with ebay it would be like that
17:20 katsmeow-afk it's been like that outside ebay too
17:20 rue_house then you hacve to try to take it up with paypal
17:20 rue_house oh, my bank does 'purchase protection'
17:21 rue_house but even if they pass the money along, the credit card company can still get it back if they want
17:21 katsmeow-afk mine too, except when i authorised payment, then they don't care if i was defrauded by the seller or not, i paid for it, they wash their paws of it all
17:21 rue_house hmm
17:22 rue_house I want to rest
17:22 rue_house I need to do firewood
17:22 tsmeow-afk feeds rue some pe
17:22 rue_house and go to the bolt store
17:22 rue_house and go to the buildign supplies store
17:22 rue_house and put a new drive in this computer
17:23 rue_house I have a fuel line tap to put in the truck
17:23 katsmeow-afk i had a list too, but i ran out of paper
17:23 rue_house just wnat to sleeeeeep
17:24 tsmeow-afk tries to add "buy more paper" to the
17:24 rue_house write that on the back of your hand
17:24 rue_house be mindfull it tends to go away after a day or two
17:24 rue_house people want me to do things too
17:25 rue_house I just want to rest
17:25 katsmeow-afk funny, the palm of my felf paw is all black with smudged writing
17:25 rue_house and have all ch chores magically be done
17:25 rue_house like the kitty litter :/
17:25 Tom_itx what should i do with these pc104 pc's?
17:25 Tom_itx toss em in the scrap bin?
17:25 rue_house na
17:25 rue_house use them for smart appliances
17:25 Tom_itx not good for anything
17:25 katsmeow-afk heck rue, you have robots, have them deal witht he kitty liter, you are supposed to be the smartest one int he whole house!
17:25 rue_house can they play mp3's>?
17:26 Tom_itx i got a tiny thing for that
17:26 rue_house I dont want to have to repair a waste handling robot
17:26 katsmeow-afk so instead you play with cat poo every day?
17:26 rue_house Tom_itx, now you can make a big one!
17:26 rue_house no, just once or twice a week
17:32 katsmeow-afk has anyone found a good reason for having sinuses?
17:32 rue_shop3 speech, resonance
17:33 katsmeow-afk but your voice doesn't change that much when they are clogged shut
17:34 katsmeow-afk plus if they wake you at 4am n pain, it's kinda hard to tell yourslef your voice will be identical int he morning when youa re pissed about not getting sleep
17:35 katsmeow-afk the channel from upper to lower cavity is only 1/8 dia anyhow, it's hard to modify voice with that little hole way up in the head
17:35 katsmeow-afk humans talk with a cleft palate, which is a much bigger hole
17:38 katsmeow-afk caffine is anotehr sore topic, caffine isn't a mental stimulant, it can be used as an insecticide, but most true mental stimulants are banned, including using the basic stimulants like pepper as a pro-histamine (as opposed to anti-histamines acting as sedatives)
17:39 katsmeow-afk you can use pepper, horseradish, etc as food flavoring, but not as keep-awakes
17:41 katsmeow-afk i did hear on tv once last week, i forget who, suggested the Japaense green horseradish as a lunch keepawake desert, instead of caffine to fight the early morning energy dropoff
17:41 katsmeow-afk err, early afternoon
17:42 katsmeow-afk it's wierd, it's like a tea company that used herbs and advertised they did what they were advertised to do, and the FDA made them stop putting the active herbs in the teas, so they took out the skullcap from sleepyime tea, and then sleepytiime no longer made people sleepy
17:46 katsmeow-afk it's like there is a huge body of info, like a planet, and there's a layer of pond scum representing the normal people, and sludge representing normal southern people, and low hanging tree branches representing government, and as the intelligent life flying over it all we must find ways down tot he main body of data at the core of it all
17:47 tsmeow-afk goes afk a w
18:02 rue_house "I dont need robots, I have genetic engineering down to a science"
18:03 rue_house kat, can you make a peanut vending amchine to get crows to bring you coins?
18:04 rue_house http://hackaday.com/2013/12/29/the-crowbox-turns-crows-into-a-cash-machine/
18:37 katsmeow-afk i dunno, you think for the cost of the machine, any crow will figure out to bring in coins? I think it would be better to have dolphins alert people where sunk ships full of gold are
18:43 tsmeow-afk decides to encrypt her communications to irc by using ROT10, then ROT6, then ROT10 a
19:04 rue_shop3 no rot 13?
19:13 katsmeow-afk i spose ROT13 twice would work too
19:22 rue_shop3 I wonder why I keep losing tenk temp sensors
19:22 rue_shop3 this is the 3rd one I'm sure
19:22 rue_shop3 I think its the wire, its shielded, and I think the capacitance is too high
19:22 katsmeow-afk the digital ones? noise, i expect
19:26 katsmeow-afk what if you sent 12v out to the sensor, put a 78L05 out there to deliver clean +5?
19:26 katsmeow-afk oh, and scope the data/clk at the recieving end, see if it ever goes negative or over +5
19:26 rue_shop3 no they are DIEING
19:26 rue_shop3 *POOF*
19:26 rue_shop3 no answer
19:27 katsmeow-afk cause if there is any Vdrop in the gnd, the data at the recieving end will look low
19:27 rue_shop3 they draw no current
19:27 rue_shop3 there is a power filter on each board
19:27 rue_shop3 the houses network is WAAAY larger and there are no problems
19:28 rue_shop3 buts its 'station z' wire, not shielded quadplex
19:28 katsmeow-afk put a t13 out there to buffer the sensor and send data more slowly?
19:28 rue_shop3 er, this is dual duplex, with individual shields
19:28 katsmeow-afk add a 4066 and you could buffer all the sensors with one t13
19:29 rue_shop3 the data rate is determined by the host computer
19:29 rue_shop3 its comm by parallel port
19:29 rue_shop3 i2c over parallel
19:29 rue_shop3 I dont understand why THAT sensor keeps being a problem
19:29 katsmeow-afk t13 talks i2c, i thought
19:29 rue_shop3 I even grounded the tank
19:29 rue_shop3 the house has more sensors over more wire, and its fine
19:29 tsmeow-afk give
19:30 rue_shop3 not looking for a new system, I'd like to know what the problem origin is
19:30 tsmeow-afk
19:30 katsmeow-afk if you don't know what all the variables are that's killing something, sometimes you need to isolate thim betetr
19:31 tsmeow-afk has something on her lil mind, afk, b
19:32 rue_shop3 and it would be easier to use standard serial over something liek rs485
19:32 rue_shop3 4 wires, +, -, RX, TX
19:32 rue_shop3 just use open collector serial
19:41 katsmeow-afk ok
19:42 katsmeow-afk i was just figuring if the sensor died while driving a t13 right beside it, then there's nothing wrong with anything from the t13 all the way back to the computer reading it
19:42 katsmeow-afk but if the t13 also dies, then the cable is bad or the power out there is bad
19:42 katsmeow-afk "divide and conquor"
19:43 rue_shop3 I'v tested the power and its a new cable
19:44 katsmeow-afk ok
19:45 rue_shop3 if they keep doing this I will switch to lm35 + t13
19:45 rue_shop3 they cost too much
19:46 rue_shop3 I liek the fact that the i2c system works via a kernel module, but I use a program to do all the readings anyhow
19:46 tsmeow-afk
20:11 katsmeow-afk ok, for $6 (plus $8 s&h, plus batteries and sd card) i got 2 working 5mp cameras (like new) with power zoom and macro and flash and autofocus , sterio robot vision, here i come!
20:18 katsmeow-afk SD Card 2GB (LOT OF 50)
20:18 katsmeow-afk $25.00
20:18 katsmeow-afk 1 bid
20:18 katsmeow-afk Free shipping
20:29 rue_shop3 :)
20:32 katsmeow-afk i think my bananananananananana plugs that were shipped out og shanghai 2 weeks ago are on the bottom of the ocean now
20:32 katsmeow-afk they had 3 container ships sink in the last 2 weeks, so the odds are pretty good i won't get them
20:34 katsmeow-afk my desk lighting turned out well, painting/reusing old galvanised roof flashing to be the fascia and hide the 5 cfl lites behind
20:35 katsmeow-afk even if it was new and $1 per foot, it still looks like $100
20:36 rue_shop3 ooo damn, I should find out whats not arrived from ebay
20:36 rue_shop3 if 3 sank, how many are left?
20:36 katsmeow-afk no one counted
20:36 rue_shop3 :S
20:36 Tom_itx did you cameras get back from their vacation?
20:36 katsmeow-afk one, on calm seas, suddenly capsized, sounds like insurance jpb to me
20:37 katsmeow-afk yeas, no memory cards, so i got no pics
20:38 katsmeow-afk i have discovered the market in old cameras is not logical, 5MP cameras canbe had for less money than 2MP cameras, and the accessories for the 5MP cameras are cheaper and more available
20:39 katsmeow-afk that said, any old camera can be had for less than a "spy camera" or any adjustable lens for any camera, plus be cheaper
20:40 katsmeow-afk of course, the smallest "spy cameras" are smaller, if you require them to be moveable inside a biological-head-copy robot head
20:41 katsmeow-afk i have not tried a lens transplant from a handheld camera to a ittybitty camera
20:42 katsmeow-afk i wonder how much i can recall from interfacing a color video camera to a C64 ~1984
20:43 katsmeow-afk nowadays i'd use static ram, and it's plenty fast enough now too
20:51 katsmeow-afk i didn't route the video thru the C64, i had a daughterbd that had the digitising and comparators, the C64 told it were in the pic to look, the card told the C64 what was there (color, intensity)
20:51 katsmeow-afk it also made a dandy color key and pic-in-pic placer
21:16 rue_house .. does dk want $390 for the same arduino uno that you can buy off ebay for $20?
21:16 Tom_itx i would hope not
21:17 rue_house http://www.digikey.ca/product-search/en?x=0&y=0&lang=en&site=ca&KeyWords=1050-1024-ND
21:17 rue_house no, thats good
21:17 rue_house https://docs.google.com/spreadsheet/pub?key=0AmdxaZwV5QYCdHNxazZpZWdGMXdRS1M2ajRyWmpYZ3c&output=html
21:17 rue_house must be a type
21:17 rue_house o
21:23 katsmeow-afk in the "try it before you leave feedback" department: the Kill Bill dvd has beeps in some scenes
21:24 rue_house huh
21:28 katsmeow-afk are you making a high speed usb dongle with four 8-bit programmable ports on it?
21:29 katsmeow-afk why only four?
21:30 Tom_itx http://s254.photobucket.com/user/TD7012/media/tumblr_mwwyqfoPr91qdlh1io1_400_zps9c8c8207.gif.html
21:31 tsmeow-afk appends her xmas list with : a usb dongle with two avr on it, one acting like a "mass storage device" and one acting like a "HID", with 4 programmable 8-bit ports per, for any use the buyer wants to use i
21:34 tsmeow-afk looks back at Tom because she doesn't know what pics to lok at on that
22:59 katsmeow-afk <slurp><slurp>
23:02 rue_shop3 I dont like usb, so dont look at me!
23:03 tsmeow-afk stops looking at
23:04 katsmeow-afk according to what i read, a hid device on usb looks like any com port to the os, but it's tons faster than the old com ports
23:12 katsmeow-afk 3. All aspects of behavior except the most routine must be improvable.
23:12 katsmeow-afk In particular, the improving mechanism should be improvable.
23:17 katsmeow-afk if i read "3812" in a pdf that i later disregard and delete, should i remember that i read the "3812" in a pdf that i later disregared and deleted, and why i disregarded it, and what time-stamped steps i took to delete it?
23:19 katsmeow-afk because even using 2^48 as the index to "things Tiggr knows" , it's possible that won't be enough pointers some day
23:19 katsmeow-afk 2^48 = 281,474,976,710,656
23:21 katsmeow-afk if she knows every human that lives for the next 200 years, there will be only 281,459,976,710,656 ptrs left, and much less if she memorises their fingerprints and all their facebook data
23:23 katsmeow-afk in fact, if she were to memorise anything of all 15 billion people, that's only allowing 19kbytes per person, and there's tons more to remember than 19kbytes of each human
23:23 katsmeow-afk so just the indexes to the data in virtual memory would be overrun at 16 billion items
23:26 katsmeow-afk just to use integral exponents of 2, if she remembered 500GB about 2^34 people, that's 9444732965739290427392 bytes, or 2^73
23:28 katsmeow-afk 9,444,732,965,739,290,427,392
23:28 katsmeow-afk roughly 9,444,732,966 terabytes
23:29 katsmeow-afk she'd need to make more than Google to afford the nuclear power plant to keep the harddrives spinning
23:29 katsmeow-afk plantS
23:34 katsmeow-afk this guy is digging himself a hole, which maybe why i had never heard of him before
23:35 katsmeow-afk at(I; desk)
23:35 katsmeow-afk at(desk; home)
23:35 katsmeow-afk ergo : at(I,home)
23:35 katsmeow-afk sold(desk,thriftstore)
23:36 katsmeow-afk ergo : at( I,thriftstore) , at least until someone takes the desk somewhere else
23:37 katsmeow-afk he has also divided up that his home is in the county but cannot drive the car in the home, but the car can be driven in the county
23:38 katsmeow-afk however, if the garage is part of the home, one does drive their car in the home
23:39 katsmeow-afk heck, even Tiggr knew you can put a full sized locomotive on a table without damaging it
23:54 katsmeow-afk https://duckduckgo.com/?q=beep+in+kill+bill
23:56 katsmeow-afk It is'nt and audio glitch.. It is supposed to be there. It was like that at the movie as was previously stated..
23:56 katsmeow-afk I guess its just another weird Quintonism.... lol
23:57 katsmeow-afk wel, that's annoying
