00:01 furrywolf yep
00:02 rrywolf hops on katsmeow-afk's lap to wait for it to
00:02 tsmeow-afk pets real slowly with tired
00:03 furrywolf :)
00:03 katsmeow-afk the corner of the house where i am putting the water pump underneath in under, is clay loam with few rocks, and has been in complete dark for 10 years, but it's also 28ft below the roof up front
00:04 katsmeow-afk all the dirt that's closer is clay, so hard it requires a jackhammer to break up
00:05 katsmeow-afk so that dirt int he buckts is a clay loam,, if i am lucky, praps i can roll it with leaf humus next year
00:05 katsmeow-afk those are all too close together, going to separate them to 40ft, ad put beans etc tween those
00:06 furrywolf it hasn't loaded yet...
00:06 tsmeow-afk
00:06 katsmeow-afk that's why i said "caution"
00:07 furrywolf nice flatbed. :)
00:08 furrywolf do you get grapes from your vine? mine has its first grapes this summer! only two bunches, but that's two more than it's ever had before.
00:12 katsmeow-afk not had any grapes myself in years, they are too high in the trees to pick, the gods would not let me tend to them
00:12 katsmeow-afk there's some wild raspberries that rea setting pretty good now tho
00:13 katsmeow-afk they are so tangled in that tree, and anotehr further down the hill, and the trees have greown so much, i need to cut them down and extract thetree from the vine, then trelliss it up, and then do trimming
00:16 furrywolf I got raspberries 2.5 years ago, and still not a single berry.
00:16 furrywolf they flower, but don't set fruit.
00:18 katsmeow-afk got bees?
00:18 furrywolf yep
00:19 katsmeow-afk got lots of water?
00:19 furrywolf yep!
00:19 katsmeow-afk hmm, i dunno
00:19 katsmeow-afk oh, all my best raspberrries are in full afternoon sun
00:19 furrywolf sun is the biggest lack around here.
00:20 katsmeow-afk what if you grow them in the tops of trees?
00:20 katsmeow-afk between the trees, on cables?
00:20 katsmeow-afk </joke>
00:20 furrywolf what if I grow them on a helium balloon floating over the cloud cover? that might work. :)
00:21 furrywolf it's not trees, it's climate.
00:21 katsmeow-afk oh
00:22 furrywolf it's so foggy here that despite some areas getting >100 inches of rain every year, the big redwoods still get ~50% of their mositure from fog.
00:22 katsmeow-afk the truck and trailer is where it's at because that is where i parked it when i last got back from Fla
00:23 katsmeow-afk i had to hop on the water situation, find energy to move and recover from the moving, and despite that being a roof garden, i had to move that dirt anyhow, and it's almost too late for any garden, but i had to try
00:24 katsmeow-afk i still have not started moving all of Tiggr back downstairs
00:29 katsmeow-afk afk a few

01:21 tsmeow-afk shows furry the bruise on her
01:25 furrywolf I'm trying to help someone in another channel fix his alternator in an rv... apparantly his wife's ventilator runs off it.
01:25 furrywolf the wiring is a hack job.
01:26 furrywolf see http://farm8.staticflickr.com/7238/7343412746_741a6c860e_k.jpg
01:27 katsmeow-afk if the browser will open .......
01:29 katsmeow-afk i hate side terminal batteries
01:29 furrywolf note the battery buddy and the car audio circuit breaker are both part of the main wiring...
01:30 katsmeow-afk ok
01:31 furrywolf I think I'm going to give up on helping him. too much crap there to troubleshoot over irc.
01:33 rrywolf curls back up for bed
01:33 tsmeow-afk ag
01:34 katsmeow-afk chances are, he has a bad ground anyhow
01:53 furrywolf ... he has a fucking broken fanbelt. he came on irc asking for wiring help, with voltage readings, etc, etc... and he has a broken fanbelt. and it takes him an hour of checking wiring to notice this.
01:53 rrywolf curls up on katsmeow-afk again and s

02:04 katsmeow-afk zzzzzzzzzzzzzzzzz
02:06 katsmeow-afk A hospital in North Carolina became concerned recently when a high number of its newborns tested positive for marijuana exposure. When researchers began looking into it, they found the culprit was chemicals found in baby soaps, including those manufactured by Johnson - Johnson, Aveeno and CVS brand products.
04:19 ShH nudges katsmeow
05:34 tsmeow-afk nudges
05:35 katsmeow-afk so, early DDR2 ram was significantly slower than the same clock speed plain DDR
05:36 katsmeow-afk because , instead of just getting the address as asked to, it wanted to fill a pipeline at least 4 deep before the data got ou, costing 5 or 6 clock cycles
05:37 tsmeow-afk makes a sighing, growling, angry s
05:39 katsmeow-afk i have some 1800 plain ddr chips in the 128k-256k, 8/16bit j-lead sop variety, and i have ~20 pounds of ddr2 in the 128meg-256meg module variety,, and damned if the 70ns ddr may be faster than the 100Mhz ddr2
05:40 katsmeow-afk and on top of it, the ddr2 is sstl-1.8 levels, and there's only one seller of lvttl-3.3/5vttl translators on ebay, at $3 per chip
05:41 tsmeow-afk nudges G
05:41 katsmeow-afk see? i have acquisition problems too
05:47 katsmeow-afk i can make translators, but it will take time, one day bottom feeding i picked up 3000 smt KST5551(npn) and MMBT5401(pnp) for 99 cents
05:48 katsmeow-afk and with a 1024-bit word, i don't need speed so much, so the transistors doing the level shifting can be slow
07:28 ShH installs himself underneath katsmeow-afk's bench and retrieves anything that falls to the f
07:29 tsmeow-afk hacks up a hair
07:30 GuShH katsmeow-afk: do I dare buy a 100MHz philips cro with dead HV?
07:31 GuShH I reckon the secondary is in heaven or perhaps it's a very stupid fault, for instance a fuse (like on the hp counter I got for cheap, the hv supply for the nixies display had an open fuse)
07:31 katsmeow-afk heh, no accounting for "value" : 5000pcs of 68.1 ohm 1% for $13, 4890pcs of 68 ohm 5% for $50 , same seller, same webpage
07:32 GuShH katsmeow-afk: do you resell what you get for cheap?
07:32 katsmeow-afk GuShH, i wouldn't, mostly because you do not know if the crt shorted internally and blew the psu, in which case you are out $100's for junk
07:33 katsmeow-afk in your case, i expect the shipping alone means you must get good equipment, even for cheap
07:34 GuShH katsmeow-afk: the model is equivalent to a tek 465
07:34 katsmeow-afk if i could have UPS/USPS pickup here, i would resell, but the cost of driving into town to the shipper is cost prohibitive, i lose money
07:34 GuShH You are right about the tube, it could've got hit and shorted out for instance
07:35 Steffanx katsmeow-afk really lives in the middle of nowhere .. ?
07:35 GuShH The tube could cost an extra 100 bucks... at least.
07:35 katsmeow-afk because of the neighbor's dogs, i must keep the gate locked, so the shipping co cannot get to the front door, and they will not wait for me to go up to them at the road
07:35 GuShH katsmeow-afk: try the audio idea, please...
07:35 GuShH you are smart enough to do it right
07:36 GuShH and no one deserves to be pinned down by fucking dogs
07:36 katsmeow-afk even without the gate, for 3 yrs i cold not get UPS delivery OR pickup because the gods wuldn't allow me to trim a low hangng branch that hit the tops of the UPS van
07:36 GuShH branches fall naturally, hint.
07:36 ShH stares at a dead branch on top of his tallest tree and shakes his
07:36 tsmeow-afk s
07:37 katsmeow-afk yeas, i keep telling rue i NEED a tree climber robot
07:37 GuShH I like that this philips has a dual time base
07:37 GuShH katsmeow-afk: oh, you don't really need to climb it, you just need to shove some big ass copper nails into the tree, the rest happens naturally.
07:37 katsmeow-afk my 7104 has 4 timebases :-P
07:37 ShH slaps katsmeow
07:37 GuShH show off.
07:38 GuShH katsmeow-afk: sometimes you gotta risk it...
07:38 katsmeow-afk most plugin timebases have a delaying or delayed timebase in them too
07:38 GuShH If I could manage to get it shipped to me at no extra cost, I may seriously consider it.
07:38 GuShH because the cost would then be a fraction of a working unit, assuming I could get it to work.
07:38 katsmeow-afk i use 7B53A, 7B92, 7B15, and the odd 7B10
07:38 GuShH A bad tube would be the end of the road for me
07:39 katsmeow-afk you need proof it works, and with a dead psu, you don't have that
07:39 GuShH well, hence the low price.
07:39 GuShH the tube doesn't look shot, but it could still be damaged.
07:39 katsmeow-afk get a Tek 2235, they go cheap and are very lightweight
07:40 katsmeow-afk the 2236 has a meter in it, don't do dat
07:40 GuShH it's odd that some have the blue tube and others the brownish one
07:41 GuShH different phosphor options I guess
07:41 katsmeow-afk different options, brightness and speed
07:41 GuShH katsmeow-afk: I don't get to choose what to buy, I get to find a bargain and decide whether it's worth risking the money or not :p
07:41 katsmeow-afk woah, scope prices have shot up lately
07:41 GuShH 22xx are notoriously bad compared to other series
07:42 GuShH low end competitive range
07:42 katsmeow-afk i have a dead 2235, powerco fried the psu,, course i cannot blame Tek, the powerco has fried everything else too
07:43 katsmeow-afk 71 hits : http://www.ebay.com/sch/i.html?_nkw=Tek*+2235
07:43 GuShH katsmeow-afk: the custom ICs scare me on these things
07:43 GuShH because I can't source parts like that.
07:43 GuShH then again it's even worse with the newest scopes I guess
07:43 katsmeow-afk then you need pre 1980's tech
07:43 GuShH hehe
07:43 GuShH I need the best tech I can get on a budget.
07:44 katsmeow-afk i never said pre-1980's was bad
07:44 GuShH If I had the money I would just call Mr. LeCroy and have him send me a scope while I eat my grapes.
07:44 katsmeow-afk the 7104 and 7912 still beat the crap outa anything made today
07:45 katsmeow-afk http://www.ebay.com/itm/Tektronix-2235-100-Mhz-Oscilloscope-Working-w-manual-/160826247800
07:45 GuShH katsmeow-afk: not an option for me to buy from ebay though.
07:45 katsmeow-afk http://www.ebay.com/itm/Tektronix-2235-2-Channel-100-MHz-Oscilloscope-/390431306576
07:45 katsmeow-afk so contact the seller directly
07:46 GuShH I can't import used goods.
07:46 katsmeow-afk wtf you want me to do?
07:46 GuShH Nothing, I was just asking for your opinion on the philips scope.
07:46 GuShH You went into eBay mode
07:46 katsmeow-afk have someone drive past the border, and "it fell off a truck"
07:46 GuShH One of these days I may
07:47 GuShH Anyway the philips is 150 usd... and it's -dead- If it were functional that would be the cheapest 100MHz scope you could ever buy in my country.
07:48 GuShH Asked the guy about the tube, he seems to import scope tubes so he should know a thing or two about them... but he could also lie all he wants.
07:48 katsmeow-afk i never used a Phillips, or saw one, i used Hitachi, Dumont, Tektronix, Lecroy, B&K, a few others, and whatever that offbrand one i i have
07:48 GuShH Philips PM3260
07:48 katsmeow-afk if he is selling a old scope, he likey cannot import a new tube or aused old tube, so you;re sol if it's bad
07:49 GuShH he sells all sorts of scopes
07:49 GuShH sometimes argues he "didn't have time to check this one so I'm selling it as-is"
07:50 GuShH which to me sounds like "it's royally fucked up and I want it out of here asap"
07:50 katsmeow-afk "didn't have time to check" = "i check the ones i can fix, this ain't it"
07:50 ShH wonders what the "mains" button does and hopes it doesn't lift gr
07:51 GuShH ground/earth
07:53 GuShH katsmeow-afk: hes giving the service manual with it... so he obviously tried to fix it.
07:54 tsmeow-afk
07:56 GuShH Is there anything worse than picking up from where a failed technician left?
07:56 katsmeow-afk nope
07:56 katsmeow-afk cause they prolly covered the original problem, without fixing it, and made more problems
07:57 katsmeow-afk they put a 741 where you need a 600Mhz opamp, and you won't know by looking at it
07:57 GuShH lol
07:59 GuShH http://www.edaboard.com/thread73809.html
07:59 GuShH interesting.
07:59 GuShH common faults are a good thing in my book
08:00 katsmeow-afk predictable
08:02 tsmeow-afk s
08:02 GuShH useless forums are useless
08:02 katsmeow-afk idiot input : [[Prisoners]] can [['scape from jail]]
08:02 katsmeow-afk CausesDesire(full_bladder,urinate) ,, i disagree, it's not a desire to urinate, it's a need, as in "i need to stop everything and urinate, even tho i'd rather not"
08:02 ShH offers katsmeow-afk some homemade orange
08:03 katsmeow-afk thanks!
08:03 katsmeow-afk yummy
08:03 GuShH It's orangetastic!
08:03 GuShH I found the trick is to add 0ml of water.
08:03 katsmeow-afk that's notmuch
08:03 Steffanx Hmm, this really is the family channel, isn't it?
08:03 GuShH Obviously, not adding water is the trick.
08:04 GuShH Steffanx: What family?
08:04 Steffanx /the/a
08:04 katsmeow-afk did something go wrong?
08:04 GuShH It should be.
08:04 GuShH So keep it in your pants?
08:05 GuShH Unless it's bees.
08:05 katsmeow-afk robot families and the hardware, circuits, and software that make them work
08:05 Steffanx Nah, it's just you discuss everything except robotics :)
08:05 GuShH scopes are part of electronics
08:05 GuShH electronics are part of robotics
08:05 katsmeow-afk test equipment?
08:05 GuShH how is discussing about scopes and failure modes not on topic :/
08:05 katsmeow-afk Steffanx, freel fee to mention robotics :-)
08:06 GuShH to quote whatshisnameagain "If you don't provide a solution, you are part of the problem"
08:07 tsmeow-afk stirrs in some water to make a sol
08:08 ShH wonders why Steffanx floats in solution but doesn't move any
08:08 katsmeow-afk you stirred too hard? the water is not a comfy temperature? he is oriented improperly for his bodily functions tooperate properly?
08:09 katsmeow-afk you can easily drown in water up to your ankles if you are in headfirst
08:10 GuShH What a jerk
08:10 katsmeow-afk hmm?
08:10 GuShH Why was he in this channel if he just complained and then left, adding nothing to it.
08:10 katsmeow-afk i dunno
08:10 katsmeow-afk i am befuddled by humans
08:11 GuShH People ask some interesting questions... I find myself spending hours to answer them correctly on my site, and I only get a comment every week or so >_<
08:11 katsmeow-afk i dunno your site
08:12 katsmeow-afk i never get email to my site, which is about the way i like it, because so far only humans would be sending the email,, or their scripted spambots
08:12 GuShH But but :( I was on hackaday and gekogeek and!
08:13 katsmeow-afk sorry, i missed it
08:13 GuShH actually someone submitted my site to make.com as well, which annoyed me.
08:13 katsmeow-afk i need to go afk and do something irl again,, i am spacing out the work making my paws red and puffy,so i don't make the blisters worse
08:14 katsmeow-afk when you get a chance, metion what your site IS
08:14 katsmeow-afk bbl
08:14 GuShH It's CRAP, so far.
09:54 GuShH katsmeow-afk: the guy guarantees the tube is fine
09:54 GuShH if that's true, it could range from a dead secondary to an open fuse
09:55 GuShH or anything in between pulling the line low, because most HV lines are current limited anyway
09:56 GuShH pictures are low quality, can't really see any burn spots on the phosphor, if they're there they turned invisible thanks to the shitty resolution.
10:03 katsmeow-afk if the psu is dead, how did he get a display to know the crt is good?
10:06 GuShH either the original owner said "it was working fine until it died" or he tested the crt
10:07 GuShH if I could get it for 100 usd shipped, I would most likely go for it.
10:59 katsmeow-afk i have tried 100 ways to lay out all these parts in the box, and it can all work except for [the transformers] OR [airflow to keep transistors cool]
11:00 GuShH katsmeow-afk: you need to think outside of the box
11:00 ShH h
11:00 katsmeow-afk i can't put them outside the box, unless i build more box to attach to the box
11:00 GuShH heatsink out
11:01 GuShH katsmeow-afk: you want 100% duty cycle on this thing?
11:01 katsmeow-afk they are electrically hot
11:01 GuShH what is it for?
11:01 katsmeow-afk the psu
11:01 GuShH yes, what is the psu for
11:02 katsmeow-afk powering things, why does everyone ask that??
11:02 GuShH o.o
11:02 GuShH to know what the desired duty cycle is, in this case.
11:02 katsmeow-afk http://designerthinking.com/benchpsu.html
11:03 katsmeow-afk what's the duty cycle got to do with it? 360watts worth of heatsinks with fans
11:04 GuShH quite a small mot actually
11:04 GuShH katsmeow-afk: duty cycle has everything to do with thermal management
11:04 GuShH take a welder, you may be able to get 100% duty with 2mm electrodes, but only 30% with 5mm
11:05 katsmeow-afk see the bottom row of pics
11:06 katsmeow-afk actually, the 3rd row of pics from the bottom
11:06 katsmeow-afk 2 pics, one missing
11:07 katsmeow-afk compare the original layout on left vs the new parts in center of page
11:08 katsmeow-afk the heatsinks are bigger, fans are bigger, there's 20watts of power resistors, 3 transformers (and i'd like a 4th), and more transistors
11:08 katsmeow-afk capacitors are bigger and 2x as many of them
11:08 katsmeow-afk i can easily put it all in the box, minus airflow
11:08 katsmeow-afk or i can do great airflow, and can't put the transformers in the box
11:09 GuShH need one extra U :p
11:09 GuShH or two...
11:12 katsmeow-afk U ?
11:14 katsmeow-afk worst case : i haveto reduce the number of psu to 4
11:15 GuShH isn't this a rack-mount unit
11:16 GuShH I basically said it would have to be twice as tall if you want it all.
11:16 ShH idly reads some of the comments left on this seller's acc
11:17 katsmeow-afk oh
11:17 ShH notices hes sold an empty instrument at least
11:17 katsmeow-afk yea, make it 3U
11:17 GuShH buyer said "something 'to be repaired' is not something with 17 missing ICs"
11:17 GuShH "and 13 burnt traces"
11:22 katsmeow-afk i've seen commercial psu with fans in series, but will that really move 2x as much air?
11:23 GuShH katsmeow-afk: not exactly twice as much
11:23 GuShH katsmeow-afk: but you can give it a go and decide whether it's worth it or not, just stack a couple 80mm fans and compare with your hand.
11:24 GuShH katsmeow-afk: if would be neat if they had a different angle at the blades
11:24 tsmeow-afk
11:24 GuShH acting as a compressor
11:24 GuShH so, two, three stages.
11:24 ShH gig
11:44 katsmeow-afk 2 in series isn't helping against any back pressure
11:44 furrywolf what're you working on?
11:49 tsmeow-afk takes a
11:56 GuShH It's so clear this guy is a ham, his responses are too short and he ignores everything but the first question, every time.
11:56 GuShH weird people.
12:01 katsmeow-afk http://designerthinking.com/images/benchpsu/DSCF2753m.jpg <<== 119k bytes
12:02 katsmeow-afk there's a lot less air thru the heatsinks than i'd like
12:03 katsmeow-afk even with two fans pushing, or onepush-one pulling
12:04 furrywolf and you can't put a fan on the top middle like they were designed for?
12:05 furrywolf flip them over so the transistors will be against each other in the middle, put the fan in the stock position?
12:05 furrywolf not enough room?
12:06 katsmeow-afk the points is the airflow as shown in http://designerthinking.com/images/benchpsu/IMG_1011.jpg
12:06 katsmeow-afk i can't just blow air whereever
12:07 katsmeow-afk if one heatsink is dissipating 60 watts, i can't have it sucking air off anotehr sink dissipating 60 watts
12:07 katsmeow-afk there will be an airtight bulkhead across the top ends of those sinks
12:08 katsmeow-afk so the air blown thru cannot be recirculated, it hasto go across to the bridges and mot
12:08 katsmeow-afk this way the caps are always in cool air and so will everything else
12:08 furrywolf more powerful fans?
12:08 furrywolf those are awfully thin looking...
12:09 katsmeow-afk i am looking, but i have power restrictions: 12v@450ma for control electronics plus fan
12:09 katsmeow-afk they blow a good bit of air if there's no pressure pushing back
12:10 furrywolf forcing air through a long run of narrow fins is always hard
12:10 katsmeow-afk yeas, this layout wasn't in my first 100 choices
12:10 furrywolf I'd try three large fans instead of six small ones.
12:11 furrywolf could always get 120v fans if power was an issue.
12:11 katsmeow-afk i'd haveto run them off the mot, so the individual psu won't be able to keep them running with the mot shut down
12:12 katsmeow-afk the mot gets frying hot, seems worse at idle, i'd prefer a thermistor controlling the fans after the mot is powered off, for which i'd need 120vac fans, or another transformer powering th efans
12:13 furrywolf look for slightly larger fans that are about twice as thick, see if the slower motor and larger blades is better at pushing air.
12:13 GuShH with no shunting that's what those cores were designed to do
12:14 ShH notices truckers are on strike and you can't buy gasoline anywhere in the cou
12:14 LoRez which country?
12:14 GuShH Argentina
12:14 LoRez fun
12:14 GuShH Also problems with natural gas.
12:14 GuShH They closed the supply to the industries
12:15 GuShH so the urban areas wouldn't get affected
12:15 furrywolf use thermal epoxy to glue heatsinks all over the core?
12:15 GuShH Places where glass is produced are risking losing their ovens too
12:15 furrywolf bbl, someone just called, needs truck repair help.
12:16 GuShH (You can't really let them cool down)
12:17 katsmeow-afk tried a much bigger fan, same current, got less air thru the sinks
12:17 GuShH this guy is a complete retard, first he tells me he can ship it over, now he says I have to pick it up.
12:17 GuShH god damn hams
12:17 katsmeow-afk core?
12:17 GuShH mot's core
12:18 katsmeow-afk i am worred about the transistors, if they are cool the mot will have enough air
12:18 GuShH there's no friggin gasoline and the guy wants me to get across town, after he explicitly said he would send it over.
12:18 GuShH how can people change their mind in a minute.
12:24 katsmeow-afk struck out on more powerful fans that will fit into the box
16:16 ferdna this looks awesome:

16:16 ferdna me wants to do it
16:42 Sunnyday Check out my latest green energy recycling video: I'm recycling delrin into gears for wind turbines and solar trackers using avocado oil: http://www.youtube.com/watch?v=CZHThkVRtMc
16:42 Sunnyday Enjoy!
16:42 Sunnyday Feel free to ask me any questions
16:45 GuShH o.O
16:47 ace4016 you keep changing your nick
16:47 ace4016 what's delrin?
16:50 Sunnyday Delrin is polyoxymethylene
16:51 ace4016 >_>
17:07 Sunnyday Did you like that?
17:11 GuShH Sunnyday: heh nathan7 from ##electronics?
17:11 GuShH (the original gear)
17:11 Sunnyday Yep
17:12 Sunnyday Nathan7, never seen him, doesn't upload videos much but he sure is smart when it comes to maths and algorithms
17:12 GuShH Yeah, too bad I left that channel
17:15 Sunnyday I like the arduino'ists, they're less nazi about off topic
17:16 GuShH Sunnyday: you should show them this http://gushh.net/tmp/arduinoshield.png
17:16 Sunnyday LOL
17:20 GuShH Sunnyday: So do you have a reprap?
17:22 Sunnyday I have a friend with a reprap I can email stl files and he posts me 3d printed parts for cheap
17:22 Sunnyday I'm a reprap customer
17:23 GuShH I need a reprap :(
17:24 GuShH But it's a big investment, at least where I'm from steppers and such are not cheap.
17:24 GuShH even when used
17:26 GuShH Sunnyday: either way I think a basic 3 axis table with an extruder head is a better option for me
17:26 GuShH blindly following a design that is constantly evolving doesn't sound good to me, I couldn't be spending money on such a thing all the time!
17:27 Sunnyday creativemachines will sell you a GOOD working mendelmax for 1300 quid
17:27 Sunnyday I haven't the cash
17:28 Sunnyday Doubt I ever will TBH
17:28 GuShH no thanks.
17:28 Sunnyday I think its more economic to mold and pour delrin into the mold
17:28 Sunnyday I'm going to try again tomorrow
17:30 GuShH a 12.6KG nema 23 costs nearly 100 usd for me
17:47 R0b0t1 GuShH: HEY!
17:47 R0b0t1 GuShH: Where've you been?
17:47 R0b0t1 Anyway,
17:47 R0b0t1 GuShH: Go fuck yourself.
17:48 katsmeow-afk <blink>
17:48 Tom_itx where did that come from?
17:48 GuShH R0b0t1: ok?
17:48 GuShH R0b0t1: go back to ##electronics and stay there, with the rest of the fuckwits.
17:49 -!- R0b0t1 was kicked from #robotics by Tom_itx!~Tl@unaffiliated/toml/x-013812 [R0b0t1]
17:49 GuShH That's why I left the channel, people like him, constantly pissing me off.
17:49 Tom_itx he'll be back
17:50 katsmeow-afk i have not spent 30 minutes in there total since 1986
17:50 GuShH And then some even dared complain about being "too harsh" when dealing with such behavior.
17:51 GuShH If I'm not an OP the only thing I can do is answer or ignore, and ignoring never solved a thing for me :(
17:51 GuShH katsmeow-afk: two fans is a no-go on the psu?
17:52 katsmeow-afk didn't seem additive
17:52 katsmeow-afk or multiplicative
17:52 katsmeow-afk and i didn't have a bigger fan that would fit the space with the same or higher hp ratings
17:53 GuShH did you run the numbers or are you designing in overkill mode?
17:53 katsmeow-afk which numbers?
17:53 GuShH thermal
17:54 katsmeow-afk i worked the transistor SOA curves and approx data (i have no real data on the heatsinks) for dissipation
17:55 katsmeow-afk by running the transitors with no insulators, i can halve the thermal barriers tween the die and the air
17:55 GuShH in theory series fans will increase pressure if used as push-pull
17:56 katsmeow-afk and by using that size sink, and alterating, interdigitating, the transisitors (npn-pnp-npn-etc) i can spread the heat a lot,, cause if you look at that sink carefully, it's real stingy on the mounting plate thickness
17:57 katsmeow-afk my paws are still stiff, i didn't do much today but move them around
17:57 GuShH You've been miming?
17:57 ShH h
17:57 katsmeow-afk i wriggle my fingers above this "keybd", and the patterns of light change on the monitor, in generally pleasing ways
17:58 katsmeow-afk it's like a Theramin, but with contact
17:59 katsmeow-afk (or however it's spelled)
17:59 GuShH You may have paws... I have a bouquet of sausages.
17:59 katsmeow-afk that must make eating tricky
17:59 GuShH (as in, fairly thick fingers)
18:00 katsmeow-afk man this channel can get off topic at the flip of a fly's wings
18:00 GuShH (some say it's because of all the boxing I did?)
18:00 Sunnyday I can only play about 8 of them so far
18:00 GuShH (others said it's because I crack my joints?)
18:00 katsmeow-afk how does being a pugilist make one's fingers fat?
18:01 GuShH katsmeow-afk: it does increase the size of your knuckles
18:01 GuShH specially if you train on hard surfaces
18:02 GuShH you're adding layers every time it heals back
18:02 katsmeow-afk layers of?
18:02 GuShH probably calcium or similar
18:02 katsmeow-afk oh
18:02 GuShH and scarred tissue
18:03 katsmeow-afk true, if you flex a bone repeatedly, microcracking it, it calciums-up, there's even post-surgical rigs to make that happen to leg and arm bones
18:03 GuShH smashing your hands against a bag full of sand and then trying to solder smt is not really the best idea.
18:04 katsmeow-afk i'll take your word for it
18:04 katsmeow-afk you ca zhanx can discuss that stuff, he does it
18:04 GuShH it's really good for managing pain though.
18:04 katsmeow-afk i heard the nukebox beeping that dinner was cooked
18:05 ShH needs a nuk
18:05 GuShH I miss it, mostly for re-heating stuff
18:05 GuShH I think I grew fond of microwave ovens after I moved
18:06 tsmeow-afk completely forgot about "Zager and Evans" , because she never heard of their names before, only the
18:06 GuShH When I was staying at the hotel I would use them all day long, since I didn't really have a real kitchen. Likewise at the apartment I rented temporarily...
18:07 GuShH Well, you pay for it and they give you a "kitchen" that consists of a sink and one little gas burner, no cookware.
18:07 katsmeow-afk naturally
18:07 GuShH Am I to travel with a frying pan and friggin knives and shit in my bag?
18:07 katsmeow-afk no, buy them locally, down the street
18:07 GuShH The place was a ripoff.
18:08 GuShH But it was the only place available during xmas
18:08 Sunnyday Halfway there to xmas now
18:08 GuShH 100 usd a night...
18:08 Sunnyday solstice been and gone
18:08 katsmeow-afk ouch
18:08 tsmeow-afk waves hi at s
18:09 GuShH had to stay for two weeks, there went my new scope budget.
18:09 GuShH life has a way of pooping in your face and smearing it all over.
18:09 GuShH Sunnyday: it's not so sunny where I'm standing!
18:14 Sunnyday Its been a soggy solstice for sure
18:15 katsmeow-afk are harddrives still doing 512 bytes/sector, or ar they doing 1024 bytes now?
18:18 katsmeow-afk because at 512megabytes per module, and 512 bytes per sector, one memory module will store a complete sector availablity map for 2 terabytes of harddrive, right?
18:18 R0b0t1 I'm sorry, it was meant to be a friendly greeting.
18:19 R0b0t1 That's actually how I say hello to him.
18:19 b0t1 goes back to lur
18:20 katsmeow-afk well, nice things about being fluent in a language is you can rearrange the letters into groups more pleasing tot he general populace
18:23 R0b0t1 Well, think I could get away with pretending to be australian and calling everyone a cunt?
18:24 katsmeow-afk i dunno for how long
18:24 katsmeow-afk humans like you i cannot understand, you can speak only in sex-related terms
18:25 katsmeow-afk and you seem to hate all the terms you use
18:55 zhanx mr?
18:55 zhanx me*
18:58 Sunnyday sex isn't all that great, it results in 9 months of your GF shouting at you then a crying baby you have to look after that drains all your time money and effort
18:59 orlok babies only cry for the first few months
19:00 katsmeow-afk that's what you think
19:01 orlok after that, if they cry, its for a good reason
19:02 orlok first 3 months.. its for no good reason
19:03 katsmeow-afk funny, it's the same crying
19:04 Sunnyday From their point of view its "I don't understand language, I've done a shit, I'm not able to move, I don't want to lie in my own shit, its disgusting, please do somethign about it
19:09 katsmeow-afk i was always stubbing my toes, i much prefereed shoes, cept they kept tying them so bloody tight
19:09 katsmeow-afk babies don't know from shit, it's warm, gooey, generally uknown, but stubbed toes hurt
19:11 katsmeow-afk tight shoes hurt
19:11 katsmeow-afk wrapped in a blanket so arms are pinned to side and cannot move, is painfull
19:12 katsmeow-afk sometimes, when very young, eyes not working right can cause issues
19:12 katsmeow-afk they usually work better after a while
19:32 rue_mohr shall I send you some slippers?
19:32 e_mohr tries to wak
19:33 katsmeow-afk GuShH , furry, compare fans in http://designerthinking.com/images/benchpsu/lilfansm.jpg vs http://designerthinking.com/images/benchpsu/bigfansm.jpg
19:34 katsmeow-afk i also toyed with this placement , but it would be a pain to build : http://designerthinking.com/images/benchpsu/couldworkm.jpg
19:34 katsmeow-afk if the caps ever swelled, it would be all over
19:41 katsmeow-afk i think i'll rearrange parts some more
19:42 rue_mohr hahahha
19:42 rue_mohr they are putting me beside a university display at hte faire, I hope I dont make them look bad }:]
19:57 katsmeow-afk go for it ;-)
19:57 katsmeow-afk i forgot dinner again, it's cold
19:58 tsmeow-afk trots off in a determined way, to eat di
20:34 tsmeow-afk cranks up the synthesiser to Darth Vader voice and kettle drum background (with various ho
20:34 katsmeow-afk dinner has been eaten
20:35 tsmeow-afk resets synth to Minnie Mouse voice and flute background (with an accustic gui
20:35 katsmeow-afk dinner has been eaten
20:36 katsmeow-afk hmm, totally different emotions for eating dinner
20:51 katsmeow-afk 3 amp with 17vdc across it = 51 watts, 4 transistors in parallel = 200 watts ,,,, well, it can take it as long as the heatsink can
20:52 rrywolf flops onto katsmeow-afk's lap, once again exhausted from
20:54 tsmeow-afk pets sl
20:56 furrywolf :)
22:09 ferdna i find binding post expensive... anyones know where to get them cheap?
22:14 rue_mohr what kind?
22:20 ferdna rue_mohr, http://www.radioshack.com/product/index.jsp?productId=2103985
22:28 rue_mohr oooh
22:28 rue_mohr you tried digikey?
22:29 rue_mohr wow 4 -5 ea
22:30 ace4016 yea, radioshack tends to hike the price up
22:30 ferdna ace4016, radio shack is the cheapest so far
22:30 ace4016 especially as they barely sell electronics components these days; too busy selling phones and consumer devices
22:30 ferdna rue_mohr, mouser and digikey are 4-5 ea.
22:31 ace4016 hrm
22:45 rue_mohr I'm down to $6 on ebay
22:45 rue_mohr $1 ea

22:54 trypsin hello
22:54 Tom_itx not done but that's somewhat the layout
22:54 trypsin i am new in robotics, but some guy could tell me how to choose a robot os?
22:54 trypsin player? or ros?
22:55 ferdna that sounds better... 11.69 is not bad... and they look goods
22:56 ace4016 robot OS? what's the scope of the robot? msot robots don't need an OS
22:57 trypsin uhr, I maybe want two robots interact with eachother
22:59 trypsin I don't need the robot to be mechanically good, but need it to be intelligently communicate with me
22:59 trypsin so i think i probably need a os on it
22:59 rue_shop no robots needs an OS
23:01 trypsin i don't understand, it will be convenient to develop if i have a of
23:01 trypsin os
23:01 Tom_itx rue_shop
23:03 trypsin I mean robot framework by os , actually
23:04 ace4016 you don't need an OS :)
23:04 ace4016 most robots are easier to develop without one infact
23:04 ace4016 although that depends on scope and tools needed
23:11 trypsin yep, i agree
23:11 trypsin thx for your advise
23:12 ace4016 it's mainly because of the low level control you'll most likely need, and most comms doesn't need an OS
23:12 ace4016 larger systems would possibly benefit from an RTOS
23:14 trypsin of course, I understand, i need some time to dig in
