00:00 rue_shop3 ^^^
00:00 rue_shop3 the 20hr discharge is about what you would expect, prettymuch a straight line
00:00 rue_shop3 thats higher
00:02 tsmeow-afk l
00:03 rue_shop3 I just got 32 of these batteries from the bank UPS
00:03 katsmeow-afk well, at least witht hat battery, you know when it hits 11.8v, it's 2/3 gone
00:03 rue_shop3 I thought it was odd that they *looked* ok
00:03 rue_shop3 so I dummy resistor tested a few and they came out good
00:03 katsmeow-afk 25 minutes @ 3amps?
00:03 rue_shop3 so i tested 16 of them and they looked good
00:04 katsmeow-afk but they aren't 5ah any more
00:04 rue_shop3 so I used that to do a 20Hr rate check and it came out good
00:04 rue_shop3 so I just tested that at what was supposed to be the 1 hr rate (3A) and it came up short
00:04 katsmeow-afk they didn't make an hr at 3 amps
00:04 rue_shop3 should have lasted an hour
00:04 tsmeow-afk
00:05 rue_shop3 however
00:05 katsmeow-afk well, it's time enough to ride out a dip, and wind up a genny
00:05 rue_shop3 I did a load sweep form 0 to 5A on some various batteries
00:05 rue_shop3 they are better than even the 18Ah batteries I have around the shop
00:06 rue_shop3 so, if nothing else, I'm learning stuff
00:06 katsmeow-afk tools are great things for that
00:06 rue_shop3 * unregulated adapters have about 9 ohms impedence
00:07 rue_shop3 now I'll try the 1Hr rate on some of the worse batteries I have around
00:08 katsmeow-afk make them look like big capacitors?
00:08 rue_shop3 I want to get a good feel for knowing how batteries age
00:09 rue_shop3 if a battery can get old and still pass a 20hr rate test, I find that verry interesting
00:10 rue_shop3 ok, at 3A, this 7Ah should last 1.5 hrs
00:11 rue_shop3 tho its almost instantly at 11.8
00:11 katsmeow-afk maybe 90 minutes
00:12 rue_shop3 ;)
00:12 rue_shop3 I have a 10A battery that dropped to 2V
00:12 rue_shop3 Ah
00:13 rue_shop3 12V
00:13 rue_shop3 so, I'm guessing thats toast
00:13 katsmeow-afk you charging them first?
00:13 rue_shop3 they should all be full
00:17 tsmeow-afk looks t
00:17 e_shop3 puts kat on a new set of
00:18 rue_shop3 part of what I want to know is how much I can speed along the test without effecting results
00:18 rue_shop3 so far its showing me its not a good idea
00:18 rue_shop3 or that real world applicatons will not meet well with lab math
00:19 rue_shop3 I suppose I can work out the watt-hours I'm getting
00:20 katsmeow-afk that's why idon't do math on most electroics unless it's plain power and smoke is a risk,, if you do math only, the last procedure is always "now make it work in the real world"
00:23 katsmeow-afk i wonder why i can't find .15 ohm resistors that i like
00:26 rue_shop3 the chart says: usable output power
00:26 rue_shop3 going with a 20Ah battery to make the numbers nice
00:26 rue_shop3 12V
00:26 rue_shop3 at 1A it'll last 20 hrs yielding 232Wh
00:27 rue_shop3 at 2A it'll last 9 hrs yeilding 209Wh
00:27 katsmeow-afk 240wh
00:27 katsmeow-afk oh, so
00:27 katsmeow-afk sorry, tires
00:27 rue_shop3 at 4A is'll last 4 hrs yeilding 186Wh
00:28 rue_shop3 at 8A, it;ll last 1.75 hrs yeilding 163Wh
00:28 rue_shop3 lead batteries suck! :)
00:28 rue_shop3 huh
00:28 rue_shop3 how did you get 240?
00:28 katsmeow-afk best price i see for 1w - 3w pwer resistors is 50 cents each
00:28 katsmeow-afk by using the wrong numbers
00:29 katsmeow-afk how do you get it?
00:29 rue_shop3 ok
00:29 rue_shop3 chart
00:29 rue_shop3 its a log chart from manufacturer X
00:29 katsmeow-afk o
00:29 rue_shop3 hard chart to find
00:32 katsmeow-afk SIEMENS 6SL3000-1BF32-5AA0 DYNAMIC BREAKING RESISTOR 967VDC 306A 200KW/3.4 OHMS $4500
00:33 katsmeow-afk i shold make acheap way to build my own low value high current resistors
00:34 rue_shop3 http://www.google.ca/url?sa=t&rct=j&q=&esrc=s&source=web&cd=2&ved=0CCMQFjAB&url=http%3A%2F%2Fwww.batteryweb.com%2Fmanuals%2Ftechman.pdf&ei=jNs1VdaKIta4ogTM7oDwBg&usg=AFQjCNHhZjNVg-6R9bCx-KODnEx_3AspnA&bvm=bv.91386359,d.cGU&cad=rja
00:34 rue_shop3 er
00:34 rue_shop3 www.batteryweb.com/manuals/techman.pdf
00:34 rue_shop3 page 6
00:35 katsmeow-afk i have all that nichrome from those 277v heaters
00:35 rue_shop3 why does google route all links for search results thru its servers?
00:35 katsmeow-afk to know what you clicked on and search you for cookies
00:35 rue_shop3 anyhow, i really suggest atleast a reacreational read thru that pdf
00:35 rue_shop3 techman.pdf
00:36 rue_shop3 thats a good document, I made that SCR charger they have in there
00:36 katsmeow-afk yo like powersonics? it's what i find in junked scooters
00:37 rue_shop3 no, I like that document
00:37 katsmeow-afk ah
00:37 rue_shop3 its one of the few documents with that chart
00:37 katsmeow-afk yeas, i have not seen this doc in any junked scooters
00:37 rue_shop3 lol
00:38 katsmeow-afk OH THE LINES !!
00:38 tsmeow-afk squ
00:38 rue_shop3 well, I'm late for bed, I'v eaten, my stomach is in its post-eating state of upsetness
00:38 rue_shop3 I'm going to bed
00:38 rue_shop3 !
00:38 katsmeow-afk while upset?
00:38 rue_shop3 talk to yo when I get there
00:38 katsmeow-afk k
00:39 rue_shop3 while(1) { while(empty) be_upset; while(full) be_upset; }
00:40 katsmeow-afk "will bounce back when theload is removed",, may ass, it's called source impedance, as the battery is discharged it goes very high impedance,, it's why a completely dead battery at first will pull no current when you drag it up to 16v with a unregulated charger
00:41 katsmeow-afk one way to determine how dead it is is to drop a load on it and measre the doop
00:41 katsmeow-afk droop
00:41 katsmeow-afk drop
00:54 katsmeow-afk 20awg = .0101 ohms/ft
00:54 katsmeow-afk so a .16 ohm resistor = 15.84 ft
00:55 katsmeow-afk 190.1 inches
00:55 rue_house * at 25c
00:55 katsmeow-afk i just remembered why i don't make my own 3w resistprs
00:55 rue_house I tried that for an element, the resistance spiked so much with temp is was almost self regulating
00:56 rue_house ah, hmm, the 7.2Ah battery lasted 2059 seconds at 3A
00:56 katsmeow-afk yeas, all maeasurements go out the window when it starts glowing
00:56 rue_house before that, I was only around 150c
00:56 rue_house had to use almost 24V to keep up with my 12V element
00:57 rue_house 34 minutes
00:57 rue_house should have lasted 1.5 hours
00:57 katsmeow-afk there's actually an olde osc circuit based on light bulbs changing resistance
00:58 katsmeow-afk it's for freqs under 10 hz
00:58 rue_house according to that chart, my 7Ah battery is at about 3Ah
00:59 tsmeow-afk hands rue a majik marker to write on the bat
00:59 rue_house :)
00:59 rue_house should I try a 20hr test on the same battery and see how it does?
00:59 katsmeow-afk big spot of white spray paint, the black marker shows up nicely
00:59 katsmeow-afk depends on how you plan on using it
01:00 rue_house hmm, I dont have many applications for a 7Ah battery that need 1/4A or less
01:00 rue_house (iirc .36A is the 20hr rate for 7Ah)
01:01 katsmeow-afk alarm circuit : fireshed roof is now missing, alert
01:01 rue_house dear god, soemthing is wrong with me, I desire to drink WATER
01:03 katsmeow-afk see how http://www.ebay.com/itm/281338350880 says 3/16 and .187 all over it?
01:03 katsmeow-afk it's .175
01:04 katsmeow-afk that said, i paid for it Saturday morning, and got it Monday in usps
01:07 katsmeow-afk and it's not 12" long, it's 11 7/8
01:11 katsmeow-afk dratit, i meant to change out my puters' ups battery today
01:14 katsmeow-afk don't yu wonder wher those people are who sang in the Cowsill's "Hair"?
01:19 katsmeow-afk first time i heard about "mold cleaner" i just had to ask why they wanted clean mold
03:07 katsmeow-afk i am getting NOWHERE in finding drive pulleys for mill spindles
03:08 katsmeow-afk the shaft is 32mm , i'd rather not mess up the shaft by having it lathed down locally, no telling how bad a job they'd do,, but i can't find any 1" bore pulleys anyhow
03:09 katsmeow-afk i been looking over 2 hours again
03:11 katsmeow-afk several people are selling 32mm mill shafts on ebay, but no one sells any way to spin them!?
03:23 katsmeow-afk carp
04:43 katsmeow-afk .
05:37 katsmeow-afk 32mm bore timing belt pulleys on Amazon start at $79

05:54 katsmeow-afk very reasonable prices, i dunno what s&h is
06:12 katsmeow-afk wow, they respond fast to email and take paypal, AND ship to the usa!
06:32 katsmeow-afk this is Twe's Day
06:34 katsmeow-afk or Tiw's Day
06:34 katsmeow-afk The English name is derived from Old English Tiwesdæg and Middle English Tewesday, meaning "Tiw's Day", the day of Tiw or Týr, the god of single combat, victory and heroic glory in Norse mythology. Tiw was equated with Mars in the interpretatio germanica, and the name of the day is a translation of Latin dies Martis.
06:35 katsmeow-afk The name Tuesday derives from the Old English "Tiwesdæg" and literally means "Tiw's Day".[1] Tiw is the Old English form of the Proto-Germanic god *Tîwaz, or Týr in Norse, a god of war and law.[2][3] *Tîwaz derives from the Proto-Indo-European base *dei-, *deya-, *didya-, meaning 'to shine', whence comes also such words as "deity".[4]
06:35 katsmeow-afk https://en.wikipedia.org/wiki/Tuesday
11:34 katsmeow-afk .,./
12:02 katsmeow-afk so i just form the nichrome into a loop and use #4 stainless steel screw to clamp it tightly to a solderable eye or wire?
12:03 katsmeow-afk heh,, imagine that,, the movie "The Shining", which i never saw, translates to ancient languages as "deity"
13:20 katsmeow-afk The input capacitor has been changed to a polyester (or similar) and with 1uF has a lower -3dB frequency of 7Hz. This may be made larger if your speakers can go lower than that.
16:37 katsmeow-afk i have a speaker that goes lower than 1 hz
16:37 katsmeow-afk i've had it for years, and it hasn't even finished the first cycle yet
16:37 katsmeow-afk it's still pushing out
16:38 katsmeow-afk i call it "my fan"
16:39 katsmeow-afk if i could replace the existing blades with flat paddle blades, swivel the blades every noon and midnite, then it could output one complete cycle every 24 hours
16:41 katsmeow-afk if i could swivel the blades 20 times per second, it would sure help to make audible bass at 10hz
16:48 katsmeow-afk hmmmmmmmmmm
16:50 katsmeow-afk if i had a large baffle, with a circular hole in it, and i centered the fan in it, on a spindle, so i could rotate the fan while it is running, and i spun the spindle at 240rpm, i might have a heck of a loud 20hz noise maker
16:52 tsmeow-afk suggests rue try this with a muffin fan, a piece of plywood with the right sized fan hole, and the l
17:32 Tom_itx new itx spread out all over the desk installing software
17:32 Tom_itx can't quite decide where to put it
17:32 Tom_itx maybe i'll hang it on the wall
18:35 katsmeow-afk call it Tapestry ?
18:35 tsmeow-afk caught a man up in one of her trees, took
18:43 katsmeow-afk the tree limb that i have been fearing would land on my car, is gone
18:44 Tom_itx i forgot how to get the menu bar at the top of file explorer...
18:45 Tom_itx on 7
18:47 katsmeow-afk under preferences?
18:48 Tom_itx not finding that yet
18:48 Tom_itx i should have just cloned the other hdd
18:48 katsmeow-afk did you try dragging and dropping the menubar?
18:49 katsmeow-afk it may be under [show] [what] [where] , in that order
18:49 Tom_itx i went thru that on the menu bar and made changes to match
18:52 Tom_itx just pisses me off i can't remember
18:52 katsmeow-afk IE 7 or 8?
18:54 Tom_itx not using that
18:54 Tom_itx this is file explorer
18:54 Tom_itx and control pannel
18:54 Tom_itx win 7 though
18:55 Tom_itx ahh! found it
18:55 katsmeow-afk start menu -> "all programs" -> etc
19:11 katsmeow-afk i need to goto grocery shop, don't want to
19:21 katsmeow-afk this place is so uncivilised: there's 5 places that make pizza in town, 2 deliver, and i cannot order a pizza
19:22 Tom_itx i like those ones that make it and you take home and bake
19:23 katsmeow-afk you mean like frozen, but not?
19:34 Tom_itx papa murphy's
19:34 Tom_itx not frozen
19:34 Tom_itx made fresh and wrapped then you bake it
19:35 katsmeow-afk i don't know them
19:35 Tom_itx probably a local or regional thing
19:36 tsmeow-afk

20:22 katsmeow-afk .. 8 pm Tuesday 4/21/2015 .. and tv is still a vast wasteland here
20:28 Tom_itx now trying to figure out windows permissions
20:28 Tom_itx not as friendly as xp
20:29 tsmeow-afk
20:33 tsmeow-afk would like some real warm lasagna and a 1/2 glass of chilled wine, pl
20:44 katsmeow-afk Tom, how much downforce is there normally on a 3/8-ish mill ?
20:44 Tom_itx what do you mean?
20:45 katsmeow-afk aka "do i really need a thrust bearing with two double-row ball bearings?"
20:45 Tom_itx i probably would
20:45 Tom_itx especially when you drill or plunge cut
20:45 Tom_itx that said, i don't think my sherline is
20:45 Tom_itx use deep grove bearings
20:46 katsmeow-afk neither drill press has one, and i don't recall seeing one in anything except big mills
20:46 Tom_itx i don't really know
20:46 katsmeow-afk i dunno the data on thse bearings
20:46 katsmeow-afk i have never felt such smooth in a ball bearing before tho
20:46 katsmeow-afk they put a lot of smooth in these
20:47 katsmeow-afk if these bearings are normal, then the R20 bearing here on the desk is pure hell
20:48 katsmeow-afk (altho not like a worn sleeve bearing)
20:48 katsmeow-afk cookie points to whoever picked up on Mousey Tongue being Mao Zedong
20:51 katsmeow-afk cookies sound good, i have none
20:55 Tom_itx this fanless board is barely warm at all
20:55 Tom_itx i'm mostly liking these boards so far
20:55 katsmeow-afk is it performing work tho?
20:55 katsmeow-afk cost?
20:55 Tom_itx been copying files all night
20:55 Tom_itx 49
20:55 Tom_itx 59?
20:55 katsmeow-afk "all night" , so it's dead slow?
20:55 katsmeow-afk url?
20:55 Tom_itx + 2 sticks of ram
20:56 katsmeow-afk oops?
20:56 Tom_L that happens every time
20:56 tsmeow-afk gooves to "Love can make you happy",, followed by saying "
20:57 katsmeow-afk what causes the disconnect?
20:57 Tom_L http://www.newegg.com/Product/Product.aspx?Item=N82E16813157565
20:57 Tom_L that was the first one i got

21:02 katsmeow-afk does the first one run xp?
21:03 Tom_itx neither
21:03 katsmeow-afk ouch
21:03 Tom_itx they are basically the same board
21:03 Tom_itx one has 2 less pci and one less pcie16 slot
21:03 Tom_itx and uses laptop memory
21:03 Tom_itx 204pin vs 240 pin iirc
21:03 katsmeow-afk where does it say what OS it will run ?
21:04 Tom_itx i don't remember but i think on the asrock site
21:04 Tom_itx xp won't install, i tried
21:04 tsmeow-afk
21:04 Tom_itx it will run 32 or 64bit 7 & up
21:05 katsmeow-afk most likely upgrade packages per mobo that no longer available
21:05 Tom_itx i'm using a pico psu on this one
21:08 Tom_itx i've been using laptop hdd lately too
21:09 Tom_itx maybe maybe not better but it makes sense they might be more rugged
21:09 Tom_itx certainly the mass is smaller

21:16 Tom_L :)
21:16 katsmeow-afk gee, superwide list of options there
21:16 Tom_L i knew what i was getting
21:17 katsmeow-afk http://www.asrock.com/support/faq.us.asp?k=winxp no data
21:18 Tom_L xp is a dead os
21:18 Tom_L sad but true
21:18 Tom_L i've got nt4 on one pc
21:18 katsmeow-afk it's perfectly useable offline
21:22 tsmeow-afk s
21:25 Tom_itx dammit i need to be able to connect to the other pc and can't figure out permissions
21:27 katsmeow-afk and dhcp and stuff
21:27 katsmeow-afk find network name
21:27 Tom_itx it finds the netname
21:28 katsmeow-afk if i want to install a thrust bearing, i need to have a land cut into the spindle so it will have something to push on
21:29 katsmeow-afk only good place and way to do it is at the bottom end, making it oversized, and a separate land in the tube below the bottom radial bearing
21:30 katsmeow-afk else, it will be pushed by the face of the bottom bearing
21:31 katsmeow-afk http://www.ebay.com/itm/291315593045 <<== double row, 32mm ID , 47mm OD
21:33 Tom_itx thin groove?
21:33 katsmeow-afk the thrust bearing will need to be wide enough to sit out on what's left of the tube after it's lathed for the spindle bearings
21:33 katsmeow-afk yeas, it's quite thin, actually
21:34 Tom_itx thick groove or offset groove and let it take the thrust
21:34 katsmeow-afk there was one other nice 32mm ID bearing on ebay, but it was quite fat, i chose many small balls rather than the few large ones
21:35 katsmeow-afk i can collar the spindle to accomodate the thrust bearing, i think, but it being big enough to sit outside the 47mm OD of the radial bearings will be a issue
21:35 katsmeow-afk i am unsure
21:36 katsmeow-afk i know there will be litlte left of the tube thickness after being milled that big of an OD
21:37 katsmeow-afk but it holds the radial bearings nicely
21:40 katsmeow-afk i am wondering if i can think outside the box, put a U extention on top of the tube, and the thrust bearing on top of the spindle, how heating of the radial bearings below will affect the bit position vertically
21:41 katsmeow-afk if i can put it there, it 1) saves me money B) saves me time up front III) lets me pick and choose the thrust bearing over more time
21:42 Tom_itx is the power front pannel connector on the MB just a toggle switch?
21:42 Tom_itx push on push off
21:43 Tom_itx i borrowed the front off another pc to work on this
21:44 katsmeow-afk not any more, it's a spst momentary to let the mobo know you pressed it
21:44 Tom_itx ok
21:44 Tom_itx so i could just short the pins temporarily
21:44 katsmeow-afk on mine, yeas
21:45 katsmeow-afk you may have heard me cussing over th elast 15 yrs sometime, when i had to get up, go round behind the cluster, and yank the cord to shut one down
21:45 Tom_itx i'll add some jumpers so i know which 2 to short
22:05 tsmeow-afk wonders if yo can define a space to mill as if it's a room, and turn a smart roomba loose i
22:09 Tom_itx i wonder if 7 has some type of sync software
22:10 Tom_itx you should see this mess...
22:10 Tom_itx 2 mice sharing 1 pad, nowhere near either pc
22:10 Tom_itx 2 kbd stacked on top of each other
22:10 Tom_itx 5 total
22:10 Tom_itx active
22:11 Tom_itx it's not surround sound... more like surround pc
22:11 katsmeow-afk heh
22:12 katsmeow-afk i have the puters on the shelf above, but the desk the keybd is on is a mess, prolly worse than rue's shop
22:12 Tom_itx the new little one is literally sitting on the desk
22:12 Tom_itx wires running to where they need to be
22:19 rue_house arg, I want to do things but I'm on the virge of falling assllepep
22:20 Tom_itx rue_house you have had that illness alot lately
22:20 katsmeow-afk told ya: not enough iodine, salt, prolly B complex
22:21 tsmeow-afk hands rue some cayenne capsules
22:21 Tom_itx how about drinking some dead sea water? it's full of minerals...
22:21 katsmeow-afk prolly way too salty
22:22 Tom_itx i hear it's deadly
22:22 Tom_itx someone brought me a bottle of it once and said not to drink it
22:22 katsmeow-afk it's true yo havetowatch the amount of sodium, because so many processed foods have sodium chloride salt, but you can be deficient in *potassium*
22:22 katsmeow-afk "deadly" as you'll wretch
22:23 Tom_itx this last hdd i got was uber thin
22:23 Tom_itx 7mm? i think
22:24 katsmeow-afk you pay extra for thinness?
22:25 Tom_itx not that i know of
22:25 Tom_itx about 60 bux
22:25 Tom_itx they were out of large ones
22:25 Tom_itx this is 500
22:25 katsmeow-afk good deal
22:26 Tom_itx plenty big for an irc pc
22:26 Tom_itx i've got plenty of spares but they're all pata
22:28 katsmeow-afk The Still steam-diesel system was designed to increase overall cycle efficiency by combining a Diesel engine with a steam engine. There were double-acting cylinders, the top half working as a Diesel, while steam acted in the bottom half ...
22:35 katsmeow-afk giving 2500 bhp per shaft at 105 rpm,.... The six forward cylinders were conventional two-stroke single-acting diesel units, of 17 in diameter by 45 in stroke....
22:47 katsmeow-afk An early practical difficulty with the internal combustion engine was fuel. Before petroleum products were available, various expedients were tried such as turpentine. However, there was a substance which was fairly readily available, and on ignition could be relied upon to produce a lot of hot gas.
22:47 katsmeow-afk That substance was gunpowder. What could possibly go wrong?
22:48 katsmeow-afk British patent No 2431 for that year. This was essentially an ambitious proposal to cover the country with windmill-driven pumps that would charge reservoirs with compressed air, to drive vehicles
22:48 rue_house "YOU PACKED IT IN!!!!?!?!?!"
22:53 katsmeow-afk horsepower man, the public wants horsepower
22:56 katsmeow-afk i wonder, if an engine has enough cylinders, and you used water as pistons, if you need 2x as much time for the water to settle before detonation , you just use 2x as many cylinders
22:57 katsmeow-afk 2500 hp from a 105 rpm engine with 6 cylinders, 17 inch pistons, 45 inch stroke
22:58 katsmeow-afk surely that could be configured to use water and drive a hydraulic motor
23:01 katsmeow-afk that's roughly 2 firings per sec, or 2 sec for the "piston" to enter and settle before detonation, if you used 12 cyl, 4 sec, if you used 24 cyl, 8 sec, and that's apretty long time, and water as pistons means you are using cheap water pipe, not high precision cylinders
23:02 katsmeow-afk even with 24 "pistons", i think you can cram the 2500 hp into a 5x10 ft space
23:08 katsmeow-afk These gyroscopes, which are carried underneath the car body, are operated within steel chambers, the pressure in which is reduced to a vacuum. Each wheel weighs about 110 lbs and revolves at a speed of 8,000 rpm.

23:20 katsmeow-afk This assumes an ideal rectifier - (i.e. a diode with no forward voltage drop, no resistance, and no junction capacitance, ... but all of these parameters are included free with real components)
23:31 katsmeow-afk Multiple tones in the ultrasound can create clearly audible phenomenon at higher sound pressures.
23:31 katsmeow-afk It can be discussed if we can tolerate the ultrasound noise generated from SACD. The noise from SACD just above 100kHz is higher in level than most of the treble in the audible range, at least when listening to the majority of acoustical music.
23:47 tsmeow-afk listens to the sounds of tatos baking in the nuk
23:48 tsmeow-afk feels better enough after rest and drugs and difefrent shoes, to go get the tools inside, finally , in additon to making dinner (by using aplate and tossing it in the nuke
