00:00 rue_bed 15.16lbs
00:01 rue_bed You have: .5lbs
00:01 rue_bed You want: kg
00:01 rue_bed * 0.22679619
00:01 rue_bed / 4.4092452
00:01 rue_bed You have: .227 liters
00:01 rue_bed You want: gallons
00:01 rue_bed * 0.059967056
00:01 rue_bed / 16.675823
00:02 rue_bed .5lbs should be .06 gallons
00:02 katsmeow-afk what is .06 gallons??
00:03 rue_bed You have: 420inch3
00:03 rue_bed You want: gallons
00:03 rue_bed * 1.8181818
00:03 rue_bed .5lbs of water is .06 gallons
00:03 rue_bed a 5 foot long 3" pipe would hold 1.8 gallons
00:03 katsmeow-afk why do i care what .5 lbs of water is?
00:03 katsmeow-afk 1.8 gallons sounds way low
00:04 rue_bed <katsmeow-afk> if i can measure with within 1/2 lbs i can have a rough analog scale of water level
00:04 katsmeow-afk oh, yeas
00:04 rue_bed just for the record, I'm not sure, but I think I'mhelping you measure water
00:04 tsmeow-afk writes that down in the recond somew
00:05 katsmeow-afk record
00:05 katsmeow-afk arg
00:05 katsmeow-afk re-cal'ing for 4" pipe.............. wait, i cannot get 4" pvc fitting locally, nvm
00:05 rue_bed I opened up google to define
00:05 rue_bed a word...
00:05 rue_bed voccation
00:05 katsmeow-afk what's voccation?
00:06 rue_bed A vocation (Latin: vocātiō "a call, summons") is an occupation to which a person
00:06 rue_bed is specially drawn or for which she/he is suited, trained, or qualified.
00:06 rue_bed familiar with the song blue monday?
00:07 katsmeow-afk yeas, but voccation != vocation
00:07 katsmeow-afk yeas
00:07 rue_bed I was trying to figure out a verse
00:08 rue_bed or is the band blue monday
00:08 tsmeow-afk imagines buying a Nissan Rogue for camping in, painting it red, and adding tough off-road gear,, making it a tough rough rouge Rogue, and seeing who canpronounce it r
00:09 rue_bed band is orgy
00:09 rue_bed k
00:09 katsmeow-afk Lyrics to 'Blue Monday' by New Order
00:09 katsmeow-afk Lyrics to 'Blue Monday' by Fats Domino
00:10 rue_bed "tell me how does it feel, to tell me who you are"
00:10 tsmeow-afk can't hear the orgy, s
00:12 tsmeow-afk wants to build something, and it will cost money, and there's something that may likely work on ebay if i mod it, and they are offering it to me at almost 1/2 price, and i am kicking myself for wanting to say
00:13 katsmeow-afk but the psu in it will cost me that much, and so will the edge connectors,, plus it's already built really nice
00:13 katsmeow-afk why do i want to say no unless they knock the price down some more?
00:14 katsmeow-afk they have not sold it in 18 months it's been listed
00:15 katsmeow-afk they offer me $50, just the edge connectors in it would cost me over $60 from China
00:15 katsmeow-afk WHY?!?
00:15 tsmeow-afk
00:18 tsmeow-afk looks at the nice device on one paw, and a sheet of steel on the other paw, and a grocery trip on the other paw, and 24 gallons of gas on the otehr
00:18 katsmeow-afk oh shit, got gas on my paw
00:19 tsmeow-afk runs to the sink for washing the
00:20 katsmeow-afk this is the start of the only January 3rd that will happen this entire year!
00:21 katsmeow-afk i wonder how long it will take for the usa to have sanctions on the entire world, and the entire world just not care any more
00:21 rue_bed I'm going to electrical person training from aug to oct this yeat
00:22 rue_bed I'm gonna have to work like a dog to make up the funds gap
00:22 katsmeow-afk but you are already an electrical person, i can see the sparks
00:23 rue_bed aparently without going to school I cant get official cert
00:23 rue_bed I challanged thru first 2 years
00:23 rue_bed one of the test questions made me laugh
00:23 rue_bed that helped
00:23 katsmeow-afk heh
00:24 katsmeow-afk they paying yo to go?
00:24 rue_bed I'm gonna have to get smooth with my trig, I need to be able to quickly wrap my head around lagging voltages and currents, even if they are leading
00:24 rue_bed no
00:24 rue_bed I think boarding is about 1600
00:25 katsmeow-afk boarding?! ouch
00:25 rue_bed tuition is about 1200
00:25 rue_bed and I have to feed myself too
00:25 rue_bed course, there is the mortguage at the same time
00:25 katsmeow-afk will laying out that much money and taking an income hit really pay off?
00:25 rue_bed and coin laundry
00:26 rue_bed that is a really good question I been asking
00:26 katsmeow-afk can you take half the course online from home?
00:26 rue_bed no online :(
00:26 rue_bed I have to go live in vancouver for 3 months
00:26 rue_bed I'm gonna be borred as hell
00:26 katsmeow-afk no online college for it from usa scools?
00:26 rue_bed no shop
00:26 rue_bed not for this
00:26 katsmeow-afk wait,,, van is just across the water
00:27 rue_bed its far enough
00:27 katsmeow-afk you goto van every day anyhow, no?
00:27 rue_bed no
00:27 katsmeow-afk oh
00:27 rue_bed if you look up 'sechelt' you will see 'gibsons' just a little south, thats the standard turf range
00:28 rue_bed sometimes up to 'madeira park' but thankfully not often
00:28 rue_bed (north)
00:28 tsmeow-afk is somewhat sad that it's prolly out of the question to anchor a boat there in su
00:29 rue_bed the ferry is ~$100/trip with a car
00:29 katsmeow-afk holyfork, and it's a state ferry!
00:29 rue_bed they are gradually comming down on live-aboards, but there is a lot of places that are open and there is no regulation of
00:30 katsmeow-afk i mean because it's best for me to launch in the gulf of mexico, and it's dangerous to boat thru Panama or south around south america
00:31 rue_bed prtage across canada
00:31 rue_bed the east end would not looks twice at ya
00:32 katsmeow-afk two boats,, a 20x20 steel boat and a 20x20 tower with 100ft legs under it? they may think "war of the worlds" and shoot at me
00:32 rue_bed matter a fact
00:33 rue_bed I'd bet if you toook a 40' sailboat, put wheels on it, gave it an AL liscence plate and drove it across canada, hardly anyone would notice
00:33 katsmeow-afk but i don't wann alive on a regular boat, they never stop wallowing around
00:33 rue_bed the cops would think it was too confusing and not want to go near it for fear of having to fill out the paperwork
00:34 katsmeow-afk "New York Times
00:34 katsmeow-afk
00:34 katsmeow-afk Chanko family filed $5 lawsuit against ABC for broadcasting their father's death ...
00:34 katsmeow-afk "
00:35 rue_bed the paperwork would be rejected, boats are the coastguards thing
00:35 rue_bed and the coastguard is so underfunded its now all volunteer and just nobody does it anymore
00:36 katsmeow-afk http://www.smnweekly.com/chanko-family-filed-5-lawsuit-against-abc-for-broadcasting-their-fathers-death-without-consent/7850/ <<== yep, $5
00:36 rue_bed so dont sink crossing alberta, nobody will be able to rescue you
00:36 katsmeow-afk more worried about the mountains just east of you
00:37 rue_bed I'v never heard of any boats having problems with them
00:37 tsmeow-afk would get seasick crossing the roc
00:38 rue_bed tis ok, they have lots of gravel
00:38 katsmeow-afk you realise, to drag the boat to the pacific, i'd be dragging it up over a mile high to cross the continental divide?
00:39 rue_bed you said the gulf was sketchy
00:39 tsmeow-afk ponders laying the sails down sideways and gliding from t
00:39 katsmeow-afk i said that?
00:39 rue_bed or go the long way around and say hi to rifraf
00:40 katsmeow-afk the gulf isn't the problem, the problem is that any way to get from the gulf to the pacific is dangerous
00:40 katsmeow-afk and pricey
00:40 rue_bed its a tiny little sliver of land, how bad could it be?
00:41 katsmeow-afk cannot sail the panama canal, it must be engine-running the whole way, and with a paid guide too
00:41 katsmeow-afk yo can maybe sail the lake, but not the canal
00:42 rue_bed wheels would fix lots ofthngs
00:42 katsmeow-afk i get 9mpg with $3.50 diesel fuel
00:43 rue_bed I meant wheels on a sail boat
00:43 katsmeow-afk the bridges over the highways in the usa are too low to hoist a sail
00:43 rue_bed oh
00:43 rue_bed what about down in panama?
00:43 katsmeow-afk they have bridges there too
00:43 rue_bed oh well what the heck!
00:44 rue_bed geez
00:44 rue_bed wait
00:44 rue_bed wait
00:44 rue_bed in the gulf, diesel is free
00:44 rue_bed you just throw over a sponge
00:45 katsmeow-afk partially true
00:45 rue_bed I'm pretty sure those things are still leaking
00:45 katsmeow-afk there are places you can park a boat, drop a 5000ft long hose, and run a generator for free
00:46 katsmeow-afk i wonder what the pressure drop wold be in a mile of garden hose
00:47 rue_bed you can run reverse current thru a saturated mosfet yes?
00:49 katsmeow-afk i am unsure
00:49 rue_bed as long as the relative gate voltage is held
00:49 rue_bed ...
00:49 rue_bed I need to switch about 12A AC
00:49 katsmeow-afk relay?
00:49 rue_bed I'd like to have less than 1V drop
00:49 katsmeow-afk triac?
00:50 katsmeow-afk hmm
00:50 rue_bed its releatedly switched, cause its for the hot bed on the printer
00:50 rue_bed I have a triac lined up, but I'm thinking
00:50 katsmeow-afk where do you get the 12vac from?
00:50 rue_bed transformer
00:50 rue_bed I'd like to switch the low voltage
00:50 katsmeow-afk oh, then switch the primary thur an optocoupler, silly
00:50 katsmeow-afk oh
00:51 rue_bed just to reduce em kickback
00:51 katsmeow-afk you can use a zero-cossing opto: moc3030 comes to mind
00:51 rue_bed I have some 3040
00:51 rue_bed and a 16A triac
00:53 katsmeow-afk you could wrap the mosfet in a full bridge diode, but it would drop ~1.8v
00:54 katsmeow-afk btw, if the mosfet has a body diode, you cannot reverse voltage across it at all, afaik
00:55 katsmeow-afk i'd switch the primary and leave the high current alone
00:57 katsmeow-afk get a cheapo lite dimmer, replace the pot with the opto?
00:59 katsmeow-afk i think any really easy solution will be pricey and use rare parts
00:59 katsmeow-afk the opto switching to the primary will at least not break the high current, it will switch on zero-crossing, and it is a low voltage interface
01:08 katsmeow-afk careful about those FOTEC SSR relays , i read they are using 5amp triacs in them and rating them for 20amps
06:57 rue_bed I dont know quite why, but it seems any kind of inudctive switching in the area causes the microcontroller to reset
08:15 Tom_itx noisy wiring?
13:54 katsmeow-afk lack of filtering on the i/o (including power) lines.... or an interrupt line floating?
13:55 katsmeow-afk woo, i won a pound of solder for $6
14:05 katsmeow-afk rue, one of the reasons olde beings like myself tend to use big filter caps and linear regulators like the 7805 is to have super flat power and 1/2 second up-time, for inductive spikes
14:06 katsmeow-afk those spike clamp devices like arc shunts and such, are great for overvolt protection, but many take too long to quench the arc, making for many cycles of brownout
14:07 katsmeow-afk in worse case situation, use a physically small choke, such as the secondary of a 1/2w audio output transformer, in a pi network, preceeding the regulator
14:08 katsmeow-afk and for dog's sake, mind the ground loops and use balanced lines on long runs
14:09 katsmeow-afk even if you use shielded line, the shield will act like a long antenna to pick up spikes
14:09 katsmeow-afk best return it to earth gnd, not to the micorcontroller board
14:15 katsmeow-afk [23:38] <rue_bed> Area is : 7.068583 <<== so a piece of 3" pvc pipe and a $20 12vdc chinese water pump @ 100psi = 700lbs of push on your mecha arm
14:38 katsmeow-afk also, use a opamp to make a 0.7v line, use 1n4148-type fast signal diodes to clamp *up* to that line, so no signal into the cpu can go below gnd
14:38 katsmeow-afk also, use a opamp to make a Vcc-0.7v line, use 1n4148-type fast signal diodes to clamp *down* to that line, so no signal into the cpu can go above Vcc
14:39 katsmeow-afk use fast high freq caps to the gnd on the cpu
14:39 katsmeow-afk you can get those diodes for cheaper than dirt in 1000 pcs reels on ebay sometimes
14:44 katsmeow-afk i suspect you have a high impedance line on the cpu that is getting above or below operating specs, and the *best* you can hope for in that case is a complete reset
19:01 rue_shop4 katsmeow-afk, an ECG circuit calls for an OP97
19:01 rue_shop4 know why they might like that one?
19:01 katsmeow-afk my condolences rue
19:02 katsmeow-afk i dunno, lemme ask Tiggr
19:02 katsmeow-afk she dunno an OP97 too
19:03 katsmeow-afk what's an OP97, and wth are following an ECG circuit?
19:03 katsmeow-afk wait, electrocargiogram?
19:03 rue_shop4 yea
19:03 rue_shop4 I'm gonna use my INA101 instrumentation amp
19:03 katsmeow-afk well, if such a thing exists, super low drift and noise
19:04 rue_shop4 https://ez.analog.com/servlet/JiveServlet/download/125183-21661/5.jpg
19:04 rue_shop4 I'm digging thru the misc op-amp drawr
19:05 katsmeow-afk that's alil wierd, that's simply draining ststic and centering the body on the instrument gnd, yo can use a 741 if yo want
19:05 rue_shop4 hmm
19:06 katsmeow-afk you can pretty much ignore that part of the circiot too, if you like, connect the ankle to R3-R2 where the opamp connects
19:06 katsmeow-afk which is, pretty much, exactly gnd
19:07 rue_shop4 so much for sticking to a plan :)
19:07 katsmeow-afk the op97 servos the body to be gnd and also tells the opter opamp about it
19:08 katsmeow-afk err, AD602 opamp
19:08 katsmeow-afk err, nm
19:09 katsmeow-afk anyhoo, the ankle is the gnd lead, with no gnd the body acts like an antenna, the trace gets real noisey
19:10 katsmeow-afk you place the other electrodes around the chest to maximise which node you want to pick up on the best
19:10 katsmeow-afk the heart has several nodes which fire sequentially, since it has 4 chambers and they cannot all fire at once
19:13 rue_shop4 its not a complex circuit
19:13 katsmeow-afk if you go hook the ankle to R2-R3, gnd is same as pin 5, and that 1% Rg can be a 6.8k, it's not critical and it's easier to find
19:16 katsmeow-afk i'd put clamp diodes on that opamp input, so static does not blow it's inputs
19:21 rue_shop4 see if I get it built or not first!
19:21 rue_shop4 how should I attach to my human...
19:22 rue_shop4 staples will puncture the extenal membrane, I dont know if its a problem or not
19:22 katsmeow-afk metal plate, thin sponge with salt water in it
19:22 rue_shop4 ok
19:22 rue_shop4 oh and I dont need to use searing hot tar to keep it on, I can just use velcro
19:23 katsmeow-afk if you use clamps, don't tighten them too much, it cut off the flow of that red liquid
19:23 e_shop4
19:24 rue_shop4 wow this board has 4 of those inst. amps
19:24 rue_shop4 they aren't cheap
19:25 katsmeow-afk low noise and low drift are important in this thing
19:25 rue_shop4 "
19:25 rue_shop4 features
19:25 rue_shop4 low drift
19:25 rue_shop4 low offset votlage
19:25 rue_shop4 low nonlinearity
19:25 rue_shop4 low noise
19:25 rue_shop4 "....
19:26 katsmeow-afk the best ones are battery or switched capacitor powered too, so there's no chance of line voltage irregularities reaching the subject
19:26 rue_shop4 I'm just wondering how (which way) I should get -5V
19:26 katsmeow-afk 7905
19:27 rue_shop4 switched capacitor, so a 555 from the +5V rail, with an inverting doubler to make -5V :)
19:27 katsmeow-afk umm, ok
19:27 rue_shop4 would op97 be bipolar or fet?
19:28 rue_shop4 oh have a datasheet
19:28 katsmeow-afk the goal would be: if the neutral and hot 120 are reversed in the wall outlet, you don't hook hot 120 to the victim
19:28 rue_shop4 not even if they are on an isolated table?
19:28 katsmeow-afk bipolar would be lower drift, imho
19:29 rue_shop4 "STAY ON THE TABLE OR YOU WILL DIE"
19:29 katsmeow-afk yeas, because they may sit up and dangle a lower appendage to the grounded floor
19:29 katsmeow-afk or touch the powered restraining table, which may be grounded
19:29 rue_shop4 ist bipolar
19:29 katsmeow-afk k
19:29 rue_shop4 741 ya think eh?
19:30 katsmeow-afk for the op97, sure
19:30 rue_shop4 "conforms to op07 pinout" oo that'll go back
19:30 katsmeow-afk add a tiny cap from patient lead to gnd if it's too noisey
19:31 rue_shop4 it was noisy till I clubbed it
19:31 katsmeow-afk it's merely a gnd servo to drain the patient of static and center them on the AD opamp's input range
19:31 rue_shop4 yup
19:32 rue_shop4 I'm gonna feel bad if this is just a inst. amp hookup, I need to make it more complex SOMEHOW
19:32 katsmeow-afk it servo's the AD sometoo, of course, to match
19:32 tsmeow-afk prepares for rue to feel
19:32 rue_shop4 I'm sure its still alive, after I hook this up, I'll know for sure
19:33 katsmeow-afk you could add more leads to it, display all nodes at once, that will make more wiring to the victim, and make them nervous
19:33 rue_shop4 I dont know where all the other ones go
19:33 rue_shop4 I'm sure there are usualyl 5 or 8
19:33 katsmeow-afk it's ok, they don't either
19:33 rue_shop4 I think you can get breathing and stuff
19:34 katsmeow-afk *i* wold know, but mere humans wouldn't
19:36 rue_shop4 well, I been looking at the op97, and I see no redeeming qualities of any kind
19:36 rue_shop4 it looks like its common mode input is about 4V off its rails
19:36 katsmeow-afk as i suspected, use thatever you have that'd good
19:36 rue_shop4 I think the 741 is only 2V off
19:37 rue_shop4 the other medical circuits I found here use lm301 and lm201
19:37 katsmeow-afk you need it to be "free from latchup" too
19:39 katsmeow-afk The OP97 will upgrade circuit designs using 725, OP05, OP07,
19:39 katsmeow-afk OP12, and 1012 type amplifiers. It may replace 741-type ampli-
19:39 katsmeow-afk fiers in circuits without nulling or where the nulling circuitry has
19:39 katsmeow-afk been removed.
19:39 katsmeow-afk lol, yep, 741
19:40 rue_shop4 :)
19:41 katsmeow-afk the OP97 is exceptionally slow, again as i expect, which is why i said you can add a cap where the ankle lead is, speed is no issue, and the circuit itself nulls the opamp's noise
19:42 katsmeow-afk stabilty is important, but as the heart isn't such a dc device, you can null the drift in software, you may need to eliminate the breathing in software too
19:42 rue_shop4 why not just... er, nevermind
19:44 rue_shop4 I'm sure there are other ways to eliminate the breathing
19:44 katsmeow-afk if you find a operator manual for the ecg/ekg machine, "breathing signal" = "sinus rhythm"
19:44 rue_shop4 hah, thats silly, thanks
19:45 rue_shop4 what if the patient has no nose?
19:45 rue_shop4 call it sinus then!
19:45 tsmeow-afk exhibits a "sinus arhyth
19:46 rue_shop4 ok hmm
19:46 e_shop4 thinks about a power supply for a
19:46 katsmeow-afk well, yanno, advanced beings don't need *every* heartbeat
19:47 katsmeow-afk you going to adc the signal, or make it tweak an analog meter?
19:47 rue_shop4 I'm partly interested in the signal strength, I'm to beleive its within the order of 10mV
19:47 rue_shop4 ->scope
19:48 katsmeow-afk yo cannot get absolute signal strength off skin readings, the nature of the fat thickness etc etc etc varies too much
19:48 rue_shop4 indeed
19:49 rue_shop4 10^6 = 1M?
19:49 katsmeow-afk plus, they show connections on the arms, that's going to make very low readings compared to the chest wall
19:49 katsmeow-afk 10meg
19:49 rue_shop4 the inst amp says its impedece is 10^10
19:49 katsmeow-afk ok
19:49 rue_shop4 I cant mentally work that out just now
19:50 katsmeow-afk 100000000000
19:50 tsmeow-afk plugged it into the
19:50 rue_shop4 hah
19:50 rue_shop4 1.0E11
19:50 katsmeow-afk 1
19:50 katsmeow-afk 100000000000
19:51 katsmeow-afk wierdness
19:51 katsmeow-afk 1x1x1x1x1x1x1x1 etc = 1
19:51 rue_shop4 its about 100 terrabytes of ohms
19:51 rue_shop4 :)
19:51 rue_shop4 er, 100Gig
19:51 katsmeow-afk Tiggr cannot store that much
19:52 rue_shop4 100gig, I lost someone in the middle
19:52 rue_shop4 shop is cold
19:52 rue_shop4 hmm
19:53 rue_shop4 9VAC
19:53 rue_shop4 would be
19:53 rue_shop4 12.6p
19:53 katsmeow-afk 11v after diodes
19:53 rue_shop4 if I do that 2cap, 2 diode thing
19:53 katsmeow-afk not enough to power up the regulators
19:53 katsmeow-afk oh, halfwave, sure
19:53 rue_shop4 I get +- 6.3ish?
19:54 katsmeow-afk prolly see ripple in the signal
19:54 rue_shop4 1.3V for dropout...
19:54 rue_shop4 yea
19:54 rue_shop4 so 12VAC
19:54 rue_shop4 16.8
19:54 rue_shop4 8.4
19:55 katsmeow-afk that should work
19:56 rue_shop4 output filter, 4.7uF?
19:56 rue_shop4 maybe stick a few ohms in there too?
19:56 rue_shop4 regulator -- 100r----(vcc)----4.7uF----gnd
19:56 katsmeow-afk i would go with 100u min, they are almost cheap as dirt in qty
19:57 rue_shop4 tho I suspect no need for rc filter
19:57 katsmeow-afk i am unsure of that ascii shematic
19:57 rue_shop4 I know going too high cuses regulator stress on powerdown
19:58 katsmeow-afk not usually, but you can put a reversed diode across the regulator if you like
19:59 rue_shop4 I wonder if I ahve any 79L05
19:59 katsmeow-afk i put 1000+ufd on the input, and a doezn ufd on the output, and never had a problem
20:00 katsmeow-afk i wouldn't go so low as 4.7u on the output, but instead of 10u single, i'd sprinkle several 4.7u around the pcb
20:00 rue_shop4 its got two amp chips kat...
20:00 katsmeow-afk true
20:01 katsmeow-afk but if you look at the output of the regulator transient responce, some capaciatance helps
20:01 katsmeow-afk <shrug> if 4.7 works, it works
20:02 rue_shop4 I'm wondering if this whole thing will work
20:02 katsmeow-afk i think i made a one opamp curcuit only once
20:02 rue_shop4 I kinda wonder how easy this is
20:02 katsmeow-afk got lfe insurance?
20:02 rue_shop4 maybe
20:02 katsmeow-afk k
20:03 rue_shop4 ok, thats a power supply, and a op-amp circuit
20:03 tsmeow-afk puts oon her arcwelding helmet and wat
20:04 katsmeow-afk wo, wind and rain suddenly picked up here
20:04 e_shop4 wonders if he should build it now or go war
20:04 rue_shop4 kat, ever heard of chopper stabalized amplfiers?
20:05 rue_shop4 going to go warm up biab
20:05 katsmeow-afk yeas, i have
20:06 katsmeow-afk you flip the signal andmake the opamp's offset work against itself
20:08 tsmeow-afk goes to see how her new rosin w
20:18 rue_shop4 one pounding of rosin?
20:32 katsmeow-afk well, the rosin works, but it's seeming stupid to use .015 thick solder to tin 16awg stranded
20:33 katsmeow-afk i ran out of .031 and .060
20:34 katsmeow-afk i got this cord from scrap yard, someone badly overheated it, the strands are all black
21:03 rue_shop4 I think sometimes a bad plastic mix will do that too
21:05 rue_shop4 ok its assembled
21:05 e_shop4 sits back and looks a
21:06 rue_shop4 my toes are still cold
21:10 katsmeow-afk not shue your toes should be cold if you assembled it right

21:20 rue_shop4 kitty looks mad
21:20 katsmeow-afk wouldn't you be if you got dressed for battle, and had to take pics instead?
21:21 rue_shop4 heh
21:22 katsmeow-afk must be a better way to clean this copper
21:23 tsmeow-afk is pondering wire brush in the dr
21:24 katsmeow-afk at 5 minutes per connection, this will take me 5.33 hours to complete
21:26 tsmeow-afk grabs the dremel and goes back upst
21:36 katsmeow-afk that works real well, actually
21:36 katsmeow-afk got set up, did 6, soldered one, in 10 minutes
21:53 katsmeow-afk i dunno why, i keep thinking of a cow and calf from 1973
21:55 katsmeow-afk we were buring off part of a 20 acre pasture, and the one cow separated from the herd, and was watching the fire, and the owner said she had recently had a calf and it was prolly in the grass fire
21:56 katsmeow-afk so i said i'd go get the calf, he said the cow wouldn't take the calf back if i touched it, if the cow cold smell me on it
21:57 katsmeow-afk and i said she would take it from me, and ran into the fire, kept going where the cow was looking, ran thru the fire with the calf, and put it down outside the fire area and backed up until the cow came forward
21:57 katsmeow-afk at which point ran back to fire control
21:57 katsmeow-afk the cow took the calf
21:59 katsmeow-afk the guy said it was the darnest thing he'd ever seen, no cow ever took a calf back that he knew of
22:04 katsmeow-afk expecting me to stand there and let the fire burn the calf alive was the darnest thing i'd ever seen
22:14 rue_shop4 hmmm
23:06 katsmeow-afk new wire wheel works even better, 3 swipes, roll it over, 3 swipes again, and it has gone from black and/or green to clean bright copper
23:09 Tom_itx rue_shop4, what's that expandable tubing material you can put over wires etc and pull it tight called?
23:09 Tom_itx http://tom-itx.no-ip.biz:81/~webpage/cnc/psu/control1.jpg
23:09 Tom_itx the blue crap there
23:09 rue_shop4 spiral or leangthwise slip?
23:09 Tom_itx length
23:09 katsmeow-afk works like the chinese finger puzzel
23:09 Tom_itx yeah
23:10 rue_shop4 oh the woven cable sheath
23:10 rue_shop4 katsmeow-afk, I'm gonna say it was a fail, too much background noise, tho a signal was there
23:10 katsmeow-afk cheap on ebay, and you can make pnumatic muscle with it
23:11 rue_shop4 tho I'm worried cause a spot where they missed an IV is geting a big bruse
23:11 katsmeow-afk rue, put the sensors on the chest 10" apart, not on the arms
23:11 rue_shop4 tired it closer, not too much difference
23:12 katsmeow-afk use shieded wire to the pads?
23:12 rue_house didn't I could play more later
23:13 katsmeow-afk i think i left a 500ft roll of rg-174 down in Fla :-(
23:16 katsmeow-afk rue, what if you set the scope to highest sensitivity and differential mode, and connect the probes to the pads?
23:20 rue_house hmm
23:20 katsmeow-afk yipes : http://i.huffpost.com/gen/2438804/thumbs/o-COCONUT-CRAB-HAWAII-2-570.jpg?1
23:20 rue_house I'll play later
23:21 katsmeow-afk According to Rob Toonen, Ph.D. professor at Hawaii Institute of Marine Biology at University of Hawaii, the crustaceans can grow up to three feet in length.
23:23 rue_house wow
23:29 Tom_itx quite a meal
23:30 Tom_itx looks rather nasty though
23:39 tsmeow-afk ponders a rum and coke as a sleep
23:40 katsmeow-afk i didn't watch any robot movies yesterday or today
23:41 Tom_itx i don't recall watching any
