00:12 rue_house nobody ever got anything in their eye?
00:12 any40179582 unknown
00:12 any40179582 i know i do
00:13 any40179582 even with glasses on
00:13 rue_house http://www.shipsnostalgia.com/guides/Image:Flamecutting1.jpg
00:14 rue_house I'd never have guessed you could cut that deep
00:14 any40179582 heck, i have gotten tings in my eyes with glasses on, AND full welding helmet on, AND a hat on top!
00:14 any40179582 yeas, plasma cutters are awesome
00:15 rue_house I suppose this is all done in china now
00:15 any40179582 they have one where i buy metals, can start in the middle of a cold sheet of 6" thick steel and punch right thru
00:15 any40179582 hasto run over either scrap, concrete, or water,, else it will just keep cutting thru anything under it
00:16 rue_house http://www.shipsnostalgia.com/guides/images/1/1e/Koperslagerij.jpg <-- "HAS ANYONE MANAGED TO BEND A PIPE THE WAY I NEED IT!!?!?!?"
00:16 rue_house :)
00:16 any40179582 and, you can put the lit torchhead underwater to cut
00:16 any40179582 lol
00:17 any40179582 yeas, i looked at all that copper, and wondered what the heck they were doing
00:18 rue_house http://www.shipsnostalgia.com/guides/images/b/b7/Mainjournalsmachined1.jpg <-- "Please do not stand on lathe carrige."
00:19 any40179582 there's a pic of guys not only standing on the T-table, but *inside* the thing clamped to the T-table
00:20 rue_house thats place must have used up an enormous amount of power
00:22 rue_house I wonder what kinda machine crashes happened in a place like that
00:23 any40179582 you know with 10hp driving a drill or mill bit, when it broke, it broke all over the place, really loudly
00:23 any40179582 and that planer, 20ft tall, planing down a 15ft wide 50ft long engine head
00:24 rue_house the shavings look 1/2 thick
00:24 rue_house the one with the crankshaft segments anyhow
00:25 any40179582 ever stand around a broaching machine? i have, a much smaller one than the one on that webpage,,, and the 12" concrete floor would shudder as the bit was driven thru the steel
00:26 any40179582 it was peeling 0.1 thick stainless 1/2 inch wide 8" long off a stainless steel pipe
00:35 any40179582 http://home.comcast.net/~n6jv/8974.html
00:46 rue_bed so it could be used for true-sign inverters
00:47 any40179582 y e a s
01:02 any40179582 too funny: http://www.ebay.com/itm/366-1058-07-Tektronix-Knob-/250958849192 click the image to open the popup, then click the popup to magnify, then watch the knob move away from the cursor as you move it
01:04 rue_bed shoudl I build rs232 level converter boards if I can buy them for 1.50 on ebay?
01:04 any40179582 only if the ones on ebat do all you want, and you don't have time, or they are cheaper on ebay
01:05 rue_bed shoudl I skip half this process and buy usb to ttl serial adapters for $2 ea?
01:05 rue_bed hmm
01:40 y40179582 wants to go put her hind paws up, w/o people shoes on

12:04 katsmeow-afk 74F14 74F14SCX SOP3.9mm (SOP-14)
12:04 katsmeow-afk US $0.16 / piece
12:04 katsmeow-afk Shipping: US $10.00 / piece
12:07 katsmeow-afk vs
12:07 katsmeow-afk QTY: 342 UNITS P/N N74F14D Inverter Schmitt Trigger 6-Element Bipolar 14-SOIC
12:07 katsmeow-afk Current bid: US $9.99
12:07 katsmeow-afk $10.95 Standard Shipping
12:08 tsmeow-afk is glad she is sitting down, else she'd haveto sit
12:10 katsmeow-afk at $0.16 each, 342 would cost $54.72 so ebay wins, but at shipping $10.00 each piece 342 would cost $3,420 so ebay wins again
12:13 tsmeow-afk looks wildly unam
12:26 katsmeow-afk cells are 156mm, or 6.14", so if i make the panels 32" by 32" outside, the cells will cover 31" by 31" inside , i can array them in 8x8ft sections
12:28 katsmeow-afk rue, lets say i have some 1/8 woodruff key stock, and i wish to use it like it was a round shaft with a knob on it, without turning the corners off the steel,, how do i make it round?
12:30 katsmeow-afk 1/8 is 0.125 across the face, is 0.177 across the corners

13:31 katsmeow-afk the otehr reason this is an old pic: back then it was "i don't care how much load you put on it, it won't break" ,, nowadays it's more like "lets mill it, saw it, grind it, cut it, thin it down until it's likely to break"

13:37 katsmeow-afk LATEST Over 300,000 attempts were made to access porn websites in the UK Houses of Parliament in the past year, records show
13:38 katsmeow-afk no wonder gov moves so slowly, they are all worn out
13:42 katsmeow-afk 1000 views per day
13:46 katsmeow-afk "Real programmers set the universal constants at the start such that the universe evolves to contain the disk with the data they want."
17:19 katsmeow-afk "student crash into a school buss at 65mph is an accident, police say the student was blinded by the sun, could not see a freaking huge school bus, but decided to keep driving at 65mph anyhow."
17:20 katsmeow-afk might as well paint the windshield black while driving, eh?
18:15 katsmeow-afk PURE KOSHER VEGETABLE GLYCERIN ? 1/4 oz - 1 GALLON 10 LBS ? FOOED GRADE ?
18:15 katsmeow-afk i am not going to eat or drink any FOOED GRADE anything

19:38 Lola8088 knock knock
21:03 katsmeow-afk <blink> 15v@4a for $6 , 19v@4.65a for $6 , both free s&h </blink>
21:21 rue_house Lola8088, there you are
21:39 katsmeow-afk whaere?
21:58 katsmeow-afk what sized 12v battery will deliver 1.2 amps for 24 hrs?
21:59 katsmeow-afk or the oem's rated 20hr rate?
23:14 rue_house google for "pdf techman lead" look for a pdf from a battery manufacturer
23:15 rue_house http://www.batteryweb.com/manuals/techman.pdf
23:15 rue_house in this case
23:15 rue_house chart on page 6
23:15 rue_house dont go gui all over the later schematics
23:16 rue_house about 30Ah
23:18 tsmeow-afk l
23:21 katsmeow-afk i instrumented my air conditioner, the math says i can run it 24 hrs on 30Ah worth of batteries (in series to make 115vac with), or 720 watts worth of solar cells if i can get 5 hrs of full charge per day
23:22 katsmeow-afk it pulls 440 watts when on, and runs only 15 minutes per hour
23:23 katsmeow-afk 3.6 amps
23:24 katsmeow-afk so the 120vac battery pack should deliver 3.6 amps max during the 15 minutes it runs, or an average of 1.2 amps for the hour
23:29 katsmeow-afk did you see the Fig 2 chart showing the drastic drop in capacity when quickly discrahrged, like in electric vehicle use?
23:31 katsmeow-afk a 100 Ah battery discharged at 300 amps reduces to only 36 Ah, and at 300 amps that's only 7 minutes
23:32 katsmeow-afk batteries get real hot at those discharge rates too, and may easily swell 1/4 inch (1cm) on each side
23:33 katsmeow-afk so don't pack them in tightly, and allow forced airflow, put a blower on the sealed pack
23:33 katsmeow-afk At any
23:33 katsmeow-afk ambient temperature, the higher the rate of discharge, the lower
23:33 katsmeow-afk the available capacity. This relationship is shown in Figure 6.
23:34 katsmeow-afk It is estimated that battery life is
23:34 katsmeow-afk halved for each 10�C above normal room temperature.
23:36 rue_house yup
23:37 rue_house thats why those charts are so neccissary to size lead-acid batteries right, cause of how poorly they perform under high current
23:40 katsmeow-afk ditto the charge current, 20 hr charges are usually a problem
23:41 katsmeow-afk those 14v 4a laptop chargers seem ideal for riding mower batteries tho
23:41 rue_house http://www.aliexpress.com/item/10-pcs-Free-Shipping-Pelse-chip-h1102-h1102nl-smd-sop-network-adapter-ic-pen/1168108674.html
23:41 rue_house THAT is a mixed up listing
23:41 katsmeow-afk gotta scope one and see why it wants to test impedance of the battery before going into full charging
23:42 katsmeow-afk it's also way too high priced
23:43 rue_house you noticed the charger schematics later in that doc?
23:43 katsmeow-afk not yet
23:43 katsmeow-afk still discoverg fig 13 and 14 give me no data
23:44 rue_house I just use the chart on page 6
23:44 rue_house :)
23:44 rue_house heat? what?
23:45 katsmeow-afk fan, blower, temp sensor
23:45 katsmeow-afk you haveto keep them clean, no road dirt, which means a sealed box, and you haveto blow out the hydrogen
23:46 katsmeow-afk and keep them cool, unless they are below 68F, at 50F you may wanna heat them,,, but you can use the hot blower exhaust off the electric motor to do that
23:47 katsmeow-afk umm, for winter up there, you may wanna consider a small LP or LNG heater for you and the batetries
23:48 katsmeow-afk the year it stayed below freezing 24-7 for a week, and hit 0F several nites, i was sooooooo happy to have a propane heater in the truck
23:50 katsmeow-afk Powerbatteries seems to like zeners, somoeone should clue them in on how those vary wildly with temperature
23:57 katsmeow-afk i think someone is trying to hide something in the code : http://www.ghostery.com/gcache/?n=Omniture%20%28Adobe%20Analytics%29&s=http%3A%2F%2Fwww.sears.com%2Fcontent%2Fpdp%2Fjavascripts%2Fexternal%2Fs_code.js%3F_%3D1378356037008&v=2&t=11
