00:00 katsmeow-afk and i used the worst distorted and sheared and bent ends on purpose, and the 26" piece of angle there has NO corners on it at 90 degrees anywhere
00:00 rue_mohr2 to make a brake?
00:01 katsmeow-afk yep
00:01 rue_mohr2 oh, the pin
00:01 katsmeow-afk you didn't see the PAGE ?
00:01 rue_mohr2 I see the image
00:01 tsmeow-afk copies down rue's bank num
00:01 rue_mohr2 I sdaw the carrage
00:01 katsmeow-afk http://designerthinking.com/brake.html
00:02 rue_mohr2 ooooh
00:02 rue_mohr2 that tells more
00:02 rue_mohr2 wow, you can really dig in with a wire brush
00:02 katsmeow-afk i could not make the pins inline and centered on the channel, so i re-referenced the whole mess, and then realised it didn't matter what scrapy scrap i used to make it
00:03 rue_mohr2 next time your at it with the camera, could you take some 'way back' images of it?
00:04 katsmeow-afk i have some, but it's just a 3" heavy channel with pins in a mass of alignment jig and vise grips,,, wanna see it/them?
00:05 rue_mohr2 yes
00:06 katsmeow-afk ok, the 3 blurry ones didn't make it, i have one clear 1.5 Mbyte wayback image
00:08 katsmeow-afk wtf
00:08 katsmeow-afk http://designerthinking.com/images/brake/L/DSCF6508.jpg
00:09 katsmeow-afk that pile of rusty steel is the lift plate, two pins, the jig aligning them all, and vise grips
00:09 katsmeow-afk really, it was barely liftable, two hands, gloves, and i can lift 80lbs on a good day
00:10 katsmeow-afk the table it's sitting on is the tablesaw
00:11 katsmeow-afk did you surface mount the to-220 leads on the underside of the pcb?
00:12 katsmeow-afk hey,, i have apile of those heatsinks!
00:12 katsmeow-afk oh, i see the lil holes for the leads
00:13 katsmeow-afk if it's not important that they be easily replaceable, you can swap the pad wiring around, and mount the to-220 in the center of the heatsink
00:14 katsmeow-afk cute lil compact design
00:23 katsmeow-afk .
00:46 rue_mohr2 nice break
00:46 rue_mohr2 I reverse bent the leads
00:46 rue_mohr2 :) thanks
00:47 rue_mohr2 most of the resistors are smt on the underside
00:48 rue_mohr2 the 2.2k are up for heat dissipation, the 1k's double as jumpers
00:48 rue_mohr2 the 7400 does dir/pwm to sideA/sideB conversion
00:49 rue_mohr2 the power transistors are both NPN
00:52 rue_mohr2 the first one I made used t0-3 transistors
00:52 rue_mohr2 to-3...
00:56 rue_mohr2 http://www.mining.com/wp-content/uploads/2013/12/300x250xship-waves-trade-333-300x250.jpg.pagespeed.ic.mORnhtHD4L.jpg
00:56 rue_mohr2 high C?
01:15 rue_mohr2 iamturnip, you dont ahppen to have a few reels of surface mount resistors in a bin there do ya?
02:43 katsmeow-afk an oil pipeline from Edmonton to Vancouver currently fills and exports via 5 oil tankers each month, the company has requested gov permission to expand the oil pipeline to fill 34 tankers each month, *five times* the ocean traffic thru the narrow Vancouver straits above Seattle
09:19 rue_mohr2 to my knowledge thats a lie, they want to put a pipeline in, so they can tank to the states, nobody wants the pipelien thru canada, and nobody wants the pipeline thru the states
09:19 rue_mohr2 we cant get politicians to realize that this is an earthquake zone
09:20 rue_mohr2 if the pipeline were going thru ottowa, it wouldn't even be concidered
10:16 katsmeow-afk but there already is a pipeline, they want to add to it
10:17 katsmeow-afk put back into service an old line, and add parallel sections to it, and double the pumping stations,, and i can't help but think the Chinese are behind it, because they bought oil sands up there and need a way to get it out of the country
10:18 katsmeow-afk there's only two ways: attach and improve the lines thru the usa down to the gulf, or thru the rockies to Burnaby/Van
10:20 katsmeow-afk it costs at least 2x more s&h to get oil to China from south america (peru, venesuela, argentina, etc) than to ship it from Canada
10:21 katsmeow-afk the cost of getting it from the gulf is driving China to propose a totally new "panama canal", which prolly won't be in Panama
10:22 katsmeow-afk China figures they'll still be shipping oil from the gulf in tanker ships in 30 years, and so a new canal will pay for itself in fees they can charge to everyone else
10:22 katsmeow-afk OR, they add more pipeline to Burnaby from the interior oil supplies
10:23 katsmeow-afk the usa is so against new pipelines and ocean oil terminals, they forced oil companies to build in Mexico instead
11:22 katsmeow-afk woah,, Nov 18 i sent msg to a seller about an item, today, Dec 18, he answered
11:37 katsmeow-afk KMM378S3227BT-G8 has KM44S16030BT driven by two(?) SN74ALVCH162836 , and the IBM 97H6242 is also covered with KM44S16030BT-G10
11:37 tsmeow-afk feels her brain mel
13:14 tsmeow-afk would like to point out that 32 pcs of 32gb usb ram is a terabyte of
13:20 katsmeow-afk a gigabyte is 2^30, 2^32 is 4 gigabytes, a terabyte is 2^40 , and harddrive LBA is 2^48 and tops out at 281 terabytes ,,, the reason this is worrysome is the ratio of harddrive space to mobo ram space is ~128:1 , and with people bidding only 1 cent on 32GB usb ram on ebay there is a huge chance someone builds a terabyte of ram for giggles
13:22 katsmeow-afk to keep with that 128:1 ratio, a serious human with money would then want to build a 128 terabyte harddrive box, which is 1/2 the max addressable with current 48bit addresses
13:23 katsmeow-afk assuming they could get cheap terabyte drive for $60, in bulk, that's $8,000 , and many people have $8000
13:23 katsmeow-afk no clue what they'd put on the drives
13:30 katsmeow-afk 64Gb usb ram $20 free s&h china , 16 of them = a terabyte for $320 , and if you put each 1-bit-wide usb channel where each bit of a pata cable is, you'd have a hell of a fast terabyte drive
14:42 katsmeow-afk so i disconnected and pulled down on the fuel line from tank, it flowed fuel by itself pretty freely enough, i reconnected it to the pump, removed line from output side, applied power from separate 12v battery, pump ran 10 minutes, no fuel appeared
14:42 katsmeow-afk i looked more pissed each minute
15:38 katsmeow-afk there's two chairs in the pic at http://graphics8.nytimes.com/images/2013/12/17/science/17FAT1_SPAN/17FAT1-articleLarge.jpg , for the man in the picture, both chairs perform exactly the same in that environment, but one of the chairs has a huge social stigma
15:40 katsmeow-afk in fact, i have 4 chairs like the one on the left in that pic, and i'd say they are more versatile and allow more mobility to the office worker than the chair on the right
15:41 katsmeow-afk iirc, rue has a chair a lot like that also, so one can say rue uses a wheelchair
15:41 katsmeow-afk but there is a huge social stigma
15:41 tsmeow-afk goes back outside to lay down under the big t
16:55 katsmeow-afk dead batteries ... batterySSSSS ... TWO dead $100 batterieSSSSS .. i guess i know the real reason som many guys drive these trucks with a generator in the back .. so they can start the truck by jumping it off the generator
19:00 katsmeow-afk so the aliens landed as agreed to, and we were still unable to communicate with them, even tho they made sounds of english letters, the words were garbled
19:00 katsmeow-afk we noticed as we drove to the reception, they'd all turn one of their heads over as we passed billboards and road signs, saying what sounded like "syenohs ta tae" and "nrut tfel on" and "nerdlihc wols"
19:00 katsmeow-afk come to find out, they studied all our textbooks upside down, and back to front
19:02 Tom_itx are single quotes ok in html?
19:02 Tom_L <meta name='robots' content='noindex'>
19:03 Tom_itx like that
19:03 katsmeow-afk i use doubles
19:03 Tom_itx yeah but my replace line doesn't work then
19:03 katsmeow-afk <meta http-equiv="Content-type" content="EN;text/html;charset=iso-8859-1"/>
19:03 katsmeow-afk <meta name="Abstract" content="pages of do-it-yourself projects"/>
19:03 Tom_itx unless huh?
19:03 katsmeow-afk afaik, this must be in " , not ' : <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
19:04 Tom_L for F in *.html; do (head -5l $F; echo " <meta name='robots' content='noindex'>"; tail -n +6 $F) > /home/tom-itx/test/new/$F; done
19:04 Tom_itx that works in linux but if i use single quotes for the echo i get errors
19:04 tsmeow-afk gets w
19:04 Tom_itx i'm sure rue can fix it but i dunno how
19:06 katsmeow-afk i pulled the front tank fuel pump and put the rear tank pump there, the dead pump makes like it's doing stuff, but it performs no work
19:06 Tom_itx sounds like alot of humans
19:06 katsmeow-afk then tried to crank it up and verify i can leave the rear pump off, the batteried dead
19:07 katsmeow-afk also, come to find out (i have been told a lot of crap about how this truck works) the fuel pump works only like 10 sec, then shuts off till the shut off the engine and restart
19:08 katsmeow-afk so the injector pump pulls a vacuum and any air in the fuel forms bubbles and kills the engine
19:09 katsmeow-afk re-fueling the lines does not get the air out of A) the lines to the injectors, or B) the line tween the filter and the injector pump
19:20 katsmeow-afk Tom, replace with something else, like | , then replace the | with "
19:21 katsmeow-afk or with two chars, like 88 , then 88 to "
19:22 tsmeow-afk goes back out to shut downt he battery charger for the
19:50 tsmeow-afk swapped that heavy charger for the 14v regulated switcher,, and wonders if it's making contact with the battery, like it did not for two days last m
19:52 katsmeow-afk nice thing about the charger good for 20amps: if the battery is really dead you know because it pops the 3amp primary breaker (3amps@120v = 30amps@12v), or it growels, or the leads spark when hittng the battery terminals
19:57 rue_mohr2 drat I HAD the flea comb, it dissapeared int eh last cleanup
19:57 rue_mohr2 it was lost for almost a month
19:57 Tom_itx i got my line to work
19:58 Tom_L for F in *.html; do (head -5l $F; echo ' <meta name="robots" content="noindex">'; tail -n +6 $F) > /home/tom-itx/test/new/$F; done
19:58 Tom_itx adds the line in the middle of a bunch of files
19:58 Tom_itx then i'll copy them back to the directory
20:03 tsmeow-afk prolly would have opened them in textpad, and replaced </title> with </title> <meta name="robots" content="noindex"> in all files, then save_all and close the ed
20:04 katsmeow-afk if yu have scripting enabled in the webserver, like php, you could simply add the line to the one header file that php prepends to your files
20:06 Tom_itx yeah i suppose i could
20:16 katsmeow-afk "searching for 'universal fuel pump' ,,,,,,,, please select vehicle model, make, year, and engine before continuing"
20:16 rue_mohr2 heh
20:16 rue_mohr2 91 ford camary
20:17 rue_mohr2 Tom_itx, did you understand the dns answer?
20:19 Tom_itx no not entirely
20:19 Tom_itx at least not in the contest of how it is shown in the router
20:22 katsmeow-afk http://www.ebay.com/itm/BRAND-NEW-E8012S-HERKO-UNIVERSAL-FUEL-PUMP-/171179051494 <<== for future references of cheap fuel pump
20:23 rue_mohr2 Tom_itx, where did you get information about you "running a dns server"
20:23 katsmeow-afk his isp
20:23 rue_mohr2 from your webserver, isp, or router?
20:23 rue_mohr2 well then they just dont know what they are talking about
20:31 Tom_itx isp
20:31 Tom_itx then i ran a test and found it was 'open
20:31 Tom_itx i put the old router on and ran the same test and it was 'closed'
20:32 rue_mohr2 right now, everythign is closed
20:33 Tom_L http://dns.measurement-factory.com/cgi-bin/openresolvercheck.pl/
20:33 Tom_itx that one
20:33 Tom_itx yeah i'm running the old router right now
20:33 Tom_itx until i can figure it out
20:33 Tom_itx they're watching my throughput for a week then i'll call em back
20:33 rue_mohr2 I think your isp is filtering too right now
20:33 katsmeow-afk another all-metal cheap 12v fuel pump : http://www.ebay.com/itm/Brand-New-1-Universal-Electric-Fuel-Pump-Replacement-For-Buick-Apollo-Cadillac-/171133716598
20:34 Tom_itx the problem didn't start until i put that router online
20:34 Tom_itx so something isn't configured right
20:34 rue_mohr2 I cant tell wheile your isp is blocking everything
20:35 tsmeow-afk wonders how those would work with 5wt oil and those balloon muscles .....
20:35 Tom_itx what do you mean by 'everything' ?
20:35 rue_mohr2 maybe they caught you in the 'dont run a webserver from your home service" clause
20:35 Tom_L i dunno
20:35 Tom_L they can't see it
20:35 Tom_L i gotta finish these files first
20:35 rue_mohr2 Tom_itx, when I try to port scan you, its all sunk, that shouldn't be
20:36 Tom_L i reset the router too so it's factory except a couple things i knew to change
20:36 tsmeow-afk ponders replacing both pumps, and using the old one to oil the bridge crane's sync chains more o
20:37 rue_mohr2 gahc, I just cant get myself to go crawl under the truck in the dark after work
20:37 katsmeow-afk you aren't me
20:38 tsmeow-afk feels all bit sore after rolling around on the cold and real lumpy concrete under her t
20:38 rue_mohr2 least you have concrete
20:38 rue_mohr2 and its not gonna be fun either, its a rework on the exhaust pipe
20:39 Tom_itx takes a bit to iterate thru a bunch of files
20:39 katsmeow-afk oh, then put it off till you can wear a full face protection and full ski mask
20:39 rue_mohr2 I'v put it off for like 4 weeks now, I have to ... oh my,... I have to keep the window rolled part way down to not get gassed
20:40 rue_mohr2 if you'll excuse me i ahve to go roll a window up, its raining
20:42 katsmeow-afk umm, well, you can wrap it real fast in that goopy white cloth plaster stuff and a tin can overwrap and hose clamps
20:43 katsmeow-afk the local stores want $65 for this : http://www.ebay.com/itm/12V-Heavy-Duty-Electric-Fuel-Pump-Universal-Metal-Solid-Diesel-or-Petrol-4-6PSI-/310787996850
20:43 rue_mohr2 its a thing where they took out the converter, and left a peice in thats 1/2" too short, and its now eaten a pipe:pipe gasket and leaks like a siv
20:44 katsmeow-afk sieve
20:44 katsmeow-afk oh
20:45 tsmeow-afk hands rue some asbestos fireplace door gasket to pound into the gap where the gasket
20:45 Tom_itx rue_bed
20:45 katsmeow-afk stull use a stainless hose clamp over it tho
20:45 Tom_itx how do you clear the bash command history?
20:49 rue_mohr2 the command history is saved in .history of the home directory
20:49 Tom_itx can you edit it?
20:49 rue_mohr2 er...
20:50 rue_mohr2 .bash_history
20:50 Tom_itx i don't see it
20:50 rue_mohr2 ^
20:50 rue_mohr2 ~/.bash_history
20:50 Tom_itx no
20:51 rue_mohr2 no?
20:51 Tom_itx in root?
20:51 rue_mohr2 thats where its stored
20:51 rue_mohr2 whoevers home dir you are
20:51 Tom_itx don't see anything
20:51 rue_mohr2 what .files do you see?
20:51 Tom_itx none
20:52 rue_mohr2 ls -la
20:52 Tom_itx must be hidden
20:52 rue_mohr2 all .files are hidden
20:52 Tom_itx how do i edit it?
20:52 rue_mohr2 type cat ~/.bash_history
20:52 rue_mohr2 does is dispaly anything
20:52 Tom_itx the history
20:53 rue_mohr2 the command 'history' will also show it
20:53 Tom_itx can i edit it?
20:53 rue_mohr2 I dont know
20:53 rue_mohr2 never tried
20:53 Tom_itx it's rw
20:54 Tom_itx -rw--------
20:54 Tom_itx -rw-------
20:54 rue_mohr2 katsmeow-afk, help

21:02 Tom_itx mmm seems ok
21:02 katsmeow-afk i wanna get done with the truck, drag the car out and feed it antifereeze, put a fan into the truck(or oil that squeely fan its got), and maybe lok at whyt he car is down
21:02 rue_shop2 .
21:03 katsmeow-afk the car is soooooooooo much better for me to drive and carry small things like groceries, glass doors, tires, 5ft tall compressor tanks, etc
21:03 Tom_itx rue_shop2, what happens if i delete bash_history?
21:03 Tom_itx will it create a new file?
21:03 rue_shop2 then you lose your history
21:03 rue_shop2 yes
21:03 rue_shop2 its not windows, it persists
21:04 Tom_itx but it didn't
21:04 Tom_itx it's still in putty
21:04 katsmeow-afk append the end date (today) and the new one will be plain ole bash_history again
21:04 katsmeow-afk (rename it)
21:06 rue_shop2 Tom_itx, yea, you ahve to restart bash
21:06 rue_shop2 its cached in session ram
21:06 rue_shop2 Tom_itx, somewhere there is a setting for the size of it, I forget where tho
21:08 Tom_itx how do you restart bash?
21:08 Tom_itx i edited the file
21:08 tsmeow-afk hands Tom a ha
21:08 Tom_itx shutdown -r now?
21:08 Tom_itx that would do it...
21:08 Tom_itx i'm sure there's an easier way
21:10 rue_shop2 exit and log back in
21:10 Tom_itx didn't work
21:10 rue_shop2 did it recreate .bash_history?
21:11 Tom_itx ok that did it
21:11 Tom_itx i thought i exited but i guess not
21:13 rue_shop2 katsmeow-afk, is tigger available?
21:14 katsmeow-afk she's not doing anything but some mining
21:14 rue_shop2 2sb772
21:14 Tom_itx ok that's enough for tonight
21:14 rue_shop2 and 2sc945
21:14 rue_shop2 all pnp?
21:14 m_itx plops back in the c

21:14 rue_shop2 ooo npn!
21:14 Tom_itx damn she's good
21:15 tsmeow-afk is proud of
21:15 rue_shop2 some kinda 3 transistor regulator or somethin
21:15 katsmeow-afk can't look up "some kinda 3 transistor regulator or somethin"
21:16 Tom_itx i was gonna cnc tonight but the oil got in the way... had to be done
21:16 Tom_itx then the files
21:16 Tom_itx were buggin me
21:17 m_itx checks those off the
21:17 tsmeow-afk sne
21:18 Tom_itx i wanted to test these engraving bits but i'm too pooped now
21:18 rue_shop2 I was forwarded a santa to fix, they put an ac adapter into him, and supposadly smoke came out
21:18 Tom_itx i spose i could edit the cad file at least
21:18 katsmeow-afk US $67.96

21:18 rue_shop2 there is some kinda regulator circuit infront of a 7805
21:18 rue_shop2 but only 1.4V gets to the 7805
21:19 katsmeow-afk base emitter short on the pnp
21:19 katsmeow-afk if the 7805 output is shorted, it may draw the input down to 1.4
21:20 katsmeow-afk before you return the santa, add a reverse polarity diode to the input
21:21 Tom_itx i bet that screws with the cadcam
21:21 Tom_itx tool id: spot drill
21:21 Tom_itx operation: finish milling
21:22 rue_shop2 the 7805 is ok
21:22 rue_shop2 yea, I dont know who didn't put a dunny diode on it
21:22 rue_shop2 dummy diode
21:28 katsmeow-afk i saw a circuit a long tme ago, allowed up to 200v applied with a 78xx output regulator, used a MJ15025(?) and set the input to the regulator to 4v over whatever the output was
21:33 rue_shop2 this is onyl 9V in
21:33 rue_shop2 I'm really curious as to why its there
21:34 Tom_itx i wonder how deep engraved lettering should be
21:34 Tom_itx .020 deep?
21:34 Tom_itx .025"
21:34 Tom_itx ?
21:38 rue_shop2 what are you engraving in/
21:38 rue_shop2 katsmeow-afk, in-circuit, all the transistors pass diode tests
21:38 Tom_itx alunimummm
21:41 Tom_itx http://tom-itx.dyndns.org:81/~webpage/cnc/pendant8.jpg
21:41 Tom_itx i think that was .025 or .030 but with the wrong cutter
21:41 rue_shop2 yea,m light
21:42 Tom_itx this old router sucks
21:47 rue_shop2 heh, katsmeow-afk less the bubble thru the face of the pnp I didn't notice
21:47 rue_shop2 fails when tested out of circuit :)
21:49 rue_shop2 yup, santa blew a transistor
21:49 Tom_itx naughty
21:50 rue_shop2 thankyou kat
22:07 tsmeow-afk curt
22:08 rue_shop2 I presume you seen a regulator like that before?
22:09 rue_shop2 :/ the end of the jaw on my new vise just fell off
22:10 katsmeow-afk well, like all electronics, details were different, i'm sure
22:10 katsmeow-afk the "end of the jaw" ?
22:11 rue_shop2 fromt eh screw to the edge just fell away
22:11 rue_shop2 cracked thru at the screw
22:11 rue_shop2 the removable bit
22:11 katsmeow-afk damn,, who is the oem on that one?
22:11 rue_shop2 "tool tech" the family got it for me :)
22:13 rue_shop2 oops, I thought about it and worked out how to make a vise from scratch
22:15 katsmeow-afk they are simple things, but for making one, that makes it hard to get a Round Tuit
22:18 katsmeow-afk i was thinking of a pair of steel 2x4, arranged like || , hinged together at the floor, swivel hinge on one at the top, fixed on the otehr, so i could clamp such things as 1ft x 1ft sheet in it
22:26 rue_shop2 I must focus, but I dont know on what
22:26 Tom_itx i'm gonna focus on some sleep
22:27 Tom_itx real quick like
22:27 rue_shop2 yea, I'm thining that just cause bedtime is 9:45 dosn't mean i ahve to stay up
22:27 rue_shop2 I really want to play tho
22:27 rue_shop2 did the guy ask about theprogrammer?
22:27 Tom_itx haven't seen anything yet
22:27 rue_shop2 k
22:27 Tom_itx but i haven't been reading all the logs either
22:28 Tom_itx not enough time in one day for everything
22:28 rue_shop2 yea
22:28 Tom_itx my engraving has finally made it to the top of the list
22:28 katsmeow-afk yep, those $16 fuel pumps are $57.19 at advance auto parts locally
22:28 Tom_itx unless it gets pushed back again
22:28 rue_shop2 I have the code for running the servomotors for the new cnc
22:28 rue_shop2 I should work on that
22:29 Tom_itx i'd like to see you get into linuxcnc
22:29 rue_shop2 me too
22:29 Tom_itx it's really pretty nice
22:29 katsmeow-afk me three
22:29 e_shop2 glances around for a scrap mac
22:29 rue_shop2 oh, I have a pile of them somewhere
22:29 Tom_itx you need to run a latency test on it before you do anything
22:29 rue_shop2 prolly in the computer room
22:29 rue_shop2 ok
22:29 Tom_itx from the live cd
22:29 rue_shop2 what tool... k
22:29 Tom_itx off their site
22:30 rue_shop2 yep
22:30 Tom_itx that's what i'm running + a bunch of updates
22:30 Tom_itx ubuntu 10.04
22:30 rue_shop2 I have servo code that takes step/dir
22:30 Tom_itx you can run from a parport or 2 if you want
22:30 Tom_itx but i REALLY like these mesa cards
22:31 Tom_itx i found something i wanted it to do but couldn't find a way.
22:31 Tom_itx within an hour somebody had written a patch for me
22:32 Tom_itx and will probably be encorporated into the next release
22:32 katsmeow-afk kool
22:33 Tom_itx was a simple patch but i didn't know how to do it
22:34 rue_shop2 hmm
22:34 rue_shop2 I need to write test code for kats project
22:35 rue_shop2 and finish my wiper code
22:36 tsmeow-afk ponders using analog volts on a key matrix and the t13's adc to decode which button was pre
22:36 Tom_itx gnite
22:37 rue_shop2 and I want to make a library for the tlc5940
22:38 katsmeow-afk gnites Tom
22:39 katsmeow-afk if you use 4 resistors to gnd on the colum lines, and 4 on the row up to a current source, then pressing each key should give you a different Vdrop across the current source
22:40 rue_shop2 and if you drop the resoluton you should be able to easily identify the button
22:40 katsmeow-afk why do it that way? cause it might be impossible to electronically wirelessly eavesdrop on the keypresses
22:41 rue_shop2 katsmeow-afk, do you have a favorite H bridge driver?
22:41 katsmeow-afk no
22:42 rue_shop2 I like that half bridge, but its big for a H bridge
22:42 rue_shop2 I like the A3952, but cant find them at a good price
22:44 katsmeow-afk for more than one h-bridge, i prefer using npn-pnp pairs, putting all the npn on one heasink and all the pnp on anotehr, that way i let make the heatsinks be hot, save on high current pcb traces
22:44 katsmeow-afk no insulations needed on the transistor mountings
22:46 tsmeow-afk is still pndering cheese and noodles or something equally bad for di
22:46 rue_shop2 oh my, I have a bunch of copier boards I scrounged and didn't look at yet
22:47 katsmeow-afk i should just nuke the pasta anyhow, i can change whay i put on them later, 20 min when they are done
22:48 katsmeow-afk i must be coming down with somethings, it's been pain to turn my head all day, the "glands" in my neck are a lil swollen
22:48 rue_shop2 L6203, whats that?
22:49 katsmeow-afk bridge driver
22:49 katsmeow-afk http://users.ece.utexas.edu/~valvano/Datasheets/L6203.pdf
22:50 katsmeow-afk i think everyone has it in stock
22:50 rue_shop2 apparently I have 4 of them
22:50 tsmeow-afk congrats
22:52 rue_shop2 then whats L297
22:52 rue_shop2 oh its for steppers
22:52 katsmeow-afk well, one good thing abot having two-way oil tankers up there every day: you can have your swimmer bot attach to one and get regular delivery/pickup to the Seattle area waterfront
22:53 rue_shop2 yea, there is a lot of anger about tankers
22:53 katsmeow-afk take pics of the clean air now, because it won't be when that many tankers show up
22:55 katsmeow-afk do like Alaska did: demand each tanker pay a fee to the locals for the trouble caused
22:56 katsmeow-afk Alaska has that "perpetual fund", each resident gets ~$1000 per yr just for living there
22:57 Tom_itx pipeline
22:57 katsmeow-afk there's too much money, it's a nation-to-nation thing, i can't see a local town stopping it
22:58 katsmeow-afk you are talking $million or more per tankerload, and one per day is pushing 1/2 $billion per year
22:58 katsmeow-afk the oil company would just buy Burnaby and kick everyone out
23:00 katsmeow-afk getting a tanker beached and leaking on one of those "national park" islands tween Van/Burn to the ocean would be a serious royal pain, it would get the usa involved too
23:01 katsmeow-afk afk to nuke some pasta, etc, bbiaf
23:04 rue_shop2 whats tigger for on tip112?
23:07 katsmeow-afk "this xmas, before you finish wrapping that practical gift, vac cleaner, ladder, cheap vise, take one more look at it,,,, have you pimped it out enough with the *best* pearl necklace or diamond bracelet or carbide mill bits you could get?"
23:07 katsmeow-afk TIP112= [!what][!electronics][!device] Material:NPN Si ; Use:med pwr ; Device:darl. ; Vceo:100V ; Current:2A ; PwrDis:50W ; Gain:1,000- ; Case:TO-220
23:08 rue_shop2 hmm 2A
23:08 rue_shop2 darl...
23:08 katsmeow-afk yea, and for the money, i'd get
23:08 katsmeow-afk TIP127= [!what][!electronics][!device] Material:PNP Si ; Use:med pwr ; Device:darl. ; Vceo:100V ; Current:5A ; PwrDis:65W ; Gain:1,000- ; Case:TO-220
23:08 katsmeow-afk istead
23:08 katsmeow-afk oops, that's pnp
23:08 katsmeow-afk but you get the idea
23:09 rue_shop2 there are 9 of them on this 9 pin printer motherboard
23:09 tsmeow-afk
23:10 katsmeow-afk TIP122= [!what][!electronics][!device] Material:NPN Si ; Use:med pwr ; Device:darl. ; Vceo:100V ; Current:5A ; PwrDis:65W ; Gain:1,000- ; Case:TO-220
23:10 katsmeow-afk the TIP line is a nice general purpose family
23:11 rue_shop2 6 x sta401 on this one
23:13 katsmeow-afk "here's that snow shovel i always wanted you to use on the driveway, and some of those custom pcb-print bow ties you have a fetish for"
23:16 tsmeow-afk keeps these TIP in stock: 41/42 , 35/36,102/107 , and i may start keeping 142
23:17 katsmeow-afk in the MPSa line i like the 42/92 , the 25/64
23:18 katsmeow-afk in 2N i ike 4401/4403 , 3904/3906 , 4401/4403
23:19 katsmeow-afk in MJ , i like 15024/15025 , 11015/11016 (and a few i never tried because of price)
23:19 katsmeow-afk TIP/2N 3055/2955 , of course
23:20 katsmeow-afk that pretty much covers 25v to 300v, and 100ma to 30amps , in smd, to-92, to-220, to-218, to-3 and modified to-3
23:22 katsmeow-afk sometimes those pop up for real low prices in qty
23:24 katsmeow-afk for instance, no one bid on 4000 KSP42, so i got them for $9 , they are a MPSA42 npn 300v 500ma to-92
23:25 katsmeow-afk the MMBT5401 is the smd version o the 2n5401 to-92 , a 160v 500ma pnp complement to the KST5551 , a npn that o one wanted 3000 of
23:27 katsmeow-afk i mean the guy put them on ebay, the least i could do was offer 0.225 *cents* each
23:27 katsmeow-afk less than 1/4 of a penny per
23:31 katsmeow-afk foooooooooooooooooood
23:32 tsmeow-afk is craving lasagna and chocolate-chocolate cake, but will have cheap pasta ins
