| ybit | haha | 00:01 |
|---|---|---|
| ybit | seems like something i would watch while under the influence | 00:02 |
| ybit | bkero: i would love to visit the osu lab sometime | 00:08 |
| ybit | if i'm out that way | 00:08 |
| ybit | do they employ students? | 00:08 |
| bkero | Aye | 00:08 |
| bkero | I'm a student. :) | 00:08 |
| ybit | do they emply non-students? | 00:09 |
| bkero | We love to give tours. | 00:09 |
| bkero | Those too | 00:09 |
| bkero | My lab is considerably noisier and colder than most. | 00:09 |
| ybit | hmm, if i had to work somewhere, something like that would fit me well | 00:09 |
| ybit | but i would probably build it myself | 00:09 |
| ybit | what's the costs of the lab? | 00:10 |
| drazak | bkero: I use osuosl all the time | 00:10 |
| ybit | drazak: via freenode? | 00:10 |
| bkero | We get a little over a million dollars in donations every year | 00:10 |
| drazak | naw | 00:10 |
| drazak | I use debian.osuosl.org and gentoo.osuosl.org and similar all the time | 00:10 |
| bkero | and it all goes into hosting open source projects and development owrk. | 00:10 |
| ybit | ah | 00:11 |
| ybit | drazak^ | 00:12 |
| ybit | bkero: nice | 00:12 |
| bkero | We host just about any open source project you can think of :) | 00:12 |
| ybit | would you be willing to host freefab.org as well eventually, say about a year from now? :) | 00:12 |
| bkero | You can put in a hosting request | 00:12 |
| ybit | will do | 00:13 |
| bkero | I can host whatever you want on my personal colocated server, as long as it's below a few gigs. | 00:13 |
| drazak | bkero: do you know Inc on irc? | 00:13 |
| drazak | part of the enlightenment project hosted on osuosl | 00:13 |
| bkero | drazak: Yes, he hangs out in our channel, and I interact with him a lot. | 00:13 |
| bkero | I haven't used E17 in about 3 years now. | 00:14 |
| drazak | is he still a dick? | 00:14 |
| bkero | Everyone at the enlightenment project is still a dick | 00:14 |
| drazak | :D | 00:14 |
| drazak | ^5 | 00:14 |
| bkero | There are bigger dicksout there though. | 00:14 |
| drazak | yeah | 00:14 |
| drazak | he's a pretty big one though | 00:14 |
| bkero | Try ULrich Drepper | 00:16 |
| bkero | http://blog.aurel32.net/?p=47 | 00:20 |
| bkero | I like how the (as opposed to this) has 4 links to bugzilla tickets where Ulrich Drepper is a complete asshole. | 00:20 |
| drazak | :P | 00:21 |
| drazak | there's someone else that's almost as much of an asshole | 00:21 |
| drazak | but I can't remember his name | 00:21 |

| Smari | samrose, y0! | 11:22 |
| kanzure | the microfluidic protein purification device is pretty neat | 11:22 |
| samrose | hey Smari | 11:22 |
| samrose | hello kanzure | 11:22 |
| kanzure | it's column chromatography but built on to a plastic device that can run on a CD drive | 11:22 |
| kanzure | hello samrose | 11:22 |
| kanzure | now that we've had our reunion.. | 11:22 |
| kanzure | oh wait. hello Smari | 11:23 |
| Smari | Hmm? | 11:23 |
| Smari | ah | 11:23 |
| Smari | yes | 11:23 |
| samrose | microfluidic protein purification sounds cool | 11:23 |
| Smari | completing the clique. | 11:23 |
| samrose | especially if it runs on CD drive | 11:23 |
| kanzure | yes | 11:23 |
| kanzure | this paper seems to claim 4 microliter samples were purified | 11:23 |
| kanzure | in particular, a variant of GFP | 11:23 |
| kanzure | I think the rpm's needed were calculated based off of the mass of GFP or something | 11:24 |
| kanzure | so that makes it a differential centrifugation fractionator or something | 11:24 |
| Smari | I built a solar funnel this morning. My backing paper was too thick and it was hard to fold into a cone, but we still got the focal point up to 106°C, which is pretty good considering that this is Iceland and the funnel sucked. | 11:24 |
| kanzure | for a cooker? | 11:24 |
| Smari | Yes | 11:24 |
| kanzure | did you want some egg omlets this morning? :) | 11:25 |
| kanzure | hm: http://www.solarcooking.org/plans/funnel.htm | 11:25 |
| Smari | If I get a better backing material I might try again, I'm fairly sure that getting it up to 250°C is possible given our 4.37 kWh/m²/day here. | 11:25 |
| kanzure | samrose: my plan is to maybe purify taq | 11:25 |

| kanzure | anyway, since it's on a CD it can easily undergo fluorescence spectrometry with the CDROM drive's laser, but unfortunately this only works for materials that are the same color as the laser. which isn't really useful if you're looking for a wide range of possibilities. | 15:41 |

| ybit | how do you select which fragments of dna to amplify? | 20:08 |
| * ybit has yet to use any of this equipment in a lab or elsewhere | 20:08 | |
| kanzure | ybit: in PCR? | 20:10 |
| kanzure | you use primers | 20:10 |
| ybit | kanzure: right, but which primers attach where? | 20:12 |
| ybit | i don't know what part i'm wanting to amplify | 20:12 |
| ybit | the first primer attaches to the 5 prime, second to the 3 prime. but which nucleotide are we targeting exactly | 20:14 |
| kanzure | primers attach by watson-crick basepairing | 20:14 |
| kanzure | so you have this 10mer or 20mer or something | 20:14 |
| kanzure | and that's your primer | 20:14 |
| kanzure | and that's one of the primers. you use another primer for the end of the sequence you want to amplify | 20:14 |
| kanzure | Commercial Club Crew - La Luna | 20:15 |
| ybit | how do you know which end is what? i'm guessing you identify this using some type of fluorescent molecule beforehand?.. | 20:16 |
| ybit | can't wait for the molecular bio course in the fall where we go over this stuff in detail | 20:17 |
| kanzure | you'll be disappointed. most of it will be from you reading a book. | 20:17 |
| ybit | i'm reading molecular biology and genomics right and i see there are tons of diff pcr methods | 20:18 |
| ybit | maybe i need to get further into the book, perhaps past chapter 2, there will be more in-depth explanations | 20:19 |
| ybit | mostly i'm just looking forward to picking the brains of my professors | 20:19 |
| ybit | most of them seem to be on break right now :\ | 20:21 |
| ybit | thus i'm in here asking basic questions, anywho, i need primers and polymerase now | 20:23 |
| kanzure | one year ago from last week my dad kicked me out of the house | 20:23 |
| kanzure | man does time fly | 20:23 |
| ybit | 'this is for your own good'? | 20:23 |
| kanzure | no | 20:23 |
| ybit | oh, why? | 20:23 |
| ybit | 'lazy bum!' | 20:24 |
| kanzure | think of it more like how mac wants to kick me off the list | 20:24 |
| kanzure | so it was like that but for the house | 20:24 |
| kanzure | anyway, now he's dead | 20:24 |
| ybit | similar to what splicer and xp_prg were talking about yesterday? ugh. | 20:24 |
| kanzure | sucks to be me | 20:24 |
| kanzure | yes, he thought that I wouldn't have any money and I would end up being a bum this was two days before he died. | 20:25 |
| ybit | at least your dad could carry on a conversation that didn't involve football | 20:27 |
| kanzure | i would give up all of the conversations that we ever had for football-conversations if he hadn't had died | 20:27 |
| kanzure | or maybe not | 20:27 |
| kanzure | or maybe notanyway | 20:27 |
| kanzure | ignore me | 20:27 |
| ybit | sports and religion is all that is on the minds of my family members | 20:28 |
| ybit | bah, it's okay, i know how you feel. around the one year mark after the girl i was dating died, i was feeling the same way. i was in depression for quite some time | 20:29 |
| ybit | two of my good friends died that year, so i can kind of relate | 20:30 |
| kanzure | he gave me a box of gum for my birthday | 20:30 |
| kanzure | my birthday was four days prior | 20:31 |
| ybit | it was a freak accident year | 20:31 |
| kanzure | two days after my birthday he told me I'd become a bum and amount to nothing | 20:31 |
| kanzure | then he proceeded to die | 20:31 |
| ybit | but i suppose it isn't best for you to focus on that one time period of his life | 20:32 |
| ybit | surely he told you quite the opposite before | 20:33 |
| kanzure | all parents do.. | 20:36 |
| kanzure | it's just what they say. even if they don't understand you. | 20:36 |
| kanzure | just nod and smile. | 20:36 |
| ybit | and parents can be wrong, etc. for instance it's taken my parents several years to get over the fact that i'm not religious, that i don't like sports, and they kind of see that my life isn't 'going to the pits' like i was told for _several_ years | 20:38 |
| QuantumG | my parents and I rarely disagreed on anything | 20:44 |
| ybit | sounds ideal | 20:44 |
| QuantumG | about 10 years ago my mum starting getting religion and I may not have suppressed a chuckle fast enough.. that got me a "don't laugh at me" but that's about the limit of our discussion on those topics. | 20:46 |
| QuantumG | and when my dad rants on about UFOs I give him plenty of shit and have some conversations with him about critical thinking, but it doesn't stop him from reading the junk | 20:46 |
| ybit | the Serial Killer DataBase... | 20:51 |
| ybit | argh | 20:51 |
| ybit | right, so purifying taq polymerase has just become important to me | 20:57 |
| ybit | and i'm also starting to doubt that i'm going to be spending less than $500 to assess my future health risks via dna sequencing | 20:59 |
| QuantumG | ya, for that you wont even get "profiling" | 20:59 |

| kanzure | for what? | 21:47 |
| kanzure | oh the wxString error from HeeksPython might have been because of some code that I manually modified | 21:48 |
| kanzure | hm | 21:48 |
| ybit | > Shit happens. Not everyone is you. Fucking learn to deal with it already. | 22:00 |
| ybit | wtf | 22:01 |
| ybit | it isn't difficult to pick out a few papers related to what you are doing | 22:01 |
| kanzure | read them, or don't. :p | 22:01 |
| * kanzure doesn't know what's so hard about that | 22:01 | |
| ybit | argh, i thought she wasn't mac, guess i'm wrong | 22:01 |
| ybit | she's mac with balls | 22:01 |
| kanzure | she privately messaged me an hour ago | 22:01 |
| kanzure | said she was off her meds | 22:02 |
| ybit | i gathered | 22:02 |
| kanzure | and that she's sorry for being a bitch | 22:02 |
| ybit | oh | 22:02 |
| ybit | okay | 22:02 |
| kanzure | she's actually a unix chick, remember, so she actually knows what I am talking about most of the time | 22:02 |
| kanzure | anyway, read the followups | 22:02 |
| ybit | getting there | 22:02 |
| ybit | or just search the archives before posting to the email list would help a lot of the redundancy | 22:09 |
| ybit | first rule of most forums is 'search before asking' | 22:09 |
| ybit | and like you said, she doesn't have to play catch up, so i just don't see why it would be difficult to sort through papers. you already did the hard work of finding the interesting papers | 22:10 |
| ybit | i like meredith, i hope she's just off her meds like she says | 22:11 |

| QuantumG | hoax isn't the right word | 22:24 |
| genehacker | oh yeah heard about what happened in diybio | 22:24 |
| QuantumG | overblown nuisance certainly comes close | 22:24 |
| kanzure | what happened in diybio, genehacker? | 22:25 |
| genehacker | well we're not that fucked | 22:25 |
| genehacker | with the garage bio magazine? | 22:25 |
| kanzure | what about it? | 22:25 |
| genehacker | they don't want to put it online for free or something like that | 22:26 |
| kanzure | no that's not it at all | 22:26 |
| kanzure | woah you got it very wrong | 22:26 |
| genehacker | oops | 22:26 |
| genehacker | only skimmed it | 22:26 |
| genehacker | thing with global warming is that it could cause mass extinctions | 22:27 |

| QuantumG | vampires | 22:29 |
| QuantumG | fun | 22:29 |
| genehacker | kanzure you ever watch the silent earth? | 22:29 |
| genehacker | another lastman on earth type movie | 22:29 |
| genehacker | involves constant change | 22:30 |
| kanzure | ohg that explains nothing about that movie | 22:32 |
| kanzure | huh | 22:32 |
| genehacker | oops the quiet earth | 22:32 |
| genehacker | well duh I don't want to give any spoilers away | 22:32 |
| kanzure | "In 1975, biological warfare between the People's Republic of China and the Soviet Union kills most of the world's human population. U.S. Army Colonel Robert Neville, M.D. (Charlton Heston) — a military scientist — begins to succumb to the plague, but vaccinates himself just in time, rendering him immune. The plague's victims, meanwhile, are reborn as "The Family" — a cult of nocturnal, vampiric mutants who seek to destroy the last vestiges of technological society." | 22:33 |
| genehacker | heh let's try not to make that plague | 22:34 |

| genehacker | energy project goes wrong, everyone ends up gone except for a few people | 22:36 |
| genehacker | energy project also ends up changing a fundamental constant of the universe too... | 22:36 |
| genehacker | hey were you guys talking about making a biosafety level 4 hot room? | 22:38 |
| genehacker | for diybio that seems a bit insane | 22:38 |
| bkero | So, I walked out to my car this evening to find this: http://staff.osuosl.org/~bkero/Pictures/flower.jpg | 22:40 |
| genehacker | though I've seen a couple of glove boxes on the trash dock at the chem building... | 22:41 |
| bkero | genehacker: You need to spend less time in not-normal garages. | 22:41 |
| genehacker | you mean such things exist? | 22:41 |
| genehacker | AWESOME! | 22:41 |
| bkero | genehacker: Ever been in a garage with a crucible and equipment to refine 99.9% pure silicon? :) | 22:41 |
| genehacker | no | 22:42 |
| genehacker | I need to see that garage | 22:42 |
| genehacker | 99% | 22:42 |
| bkero | You need to work in more awesome garages. | 22:42 |
| genehacker | ? | 22:42 |
| genehacker | bkero | 22:42 |
| genehacker | that's an awesome garage | 22:42 |
| genehacker | that's the sorta garage we need | 22:42 |
| bkero | Did I mention this crucible started out life as a microwave? ;) | 22:43 |
| genehacker | no | 22:43 |
| genehacker | hmmmm.... | 22:43 |
| bkero | Hehe, it's well documented. | 22:43 |
| genehacker | well documented? | 22:43 |
| genehacker | link? | 22:43 |
| bkero | Turning microwaves into crucibles I mean. The silicon refinement yes, but in different areas. | 22:43 |
| genehacker | but can you make a good crucible for maintaining constant temperature? | 22:44 |
| genehacker | is that semiconductor grade bkero? | 22:44 |
| bkero | Well, that's what it's being used for. | 22:45 |
| genehacker | if this garage has a crystal puller then we need to see this garage | 22:45 |
| genehacker | if this garage has a wafer cutter | 22:45 |
| genehacker | THEN WE REALLY NEED TO SEE THIS GARAGE | 22:45 |
| bkero | I haven't explored it fully, the main action was happening around the crucible and bathes. | 22:46 |
| * bkero will need to be invited back to said garage. | 22:47 | |
| ybit | genehacker: nobody was talking about a biosafety room, i was looking up biosafety standards for my home lab | 22:47 |
| genehacker | document it | 22:47 |
| genehacker | if you can | 22:47 |
| genehacker | what are they trying to do? | 22:48 |
| genehacker | are they making silicon from sand? | 22:48 |
| bkero | Yea | 22:48 |
| bkero | Fab-garage | 22:48 |
| genehacker | are they doing photolithography? | 22:48 |
| bkero | No, they're doing this to avoid photolithography | 22:49 |
| genehacker | ??? | 22:49 |
| bkero | They were using some method to carve pathes in it that wasn't masking | 22:49 |
| bkero | I'm not sure what it was, never asked | 22:50 |
| genehacker | they were making chips? | 22:56 |
| kanzure | " | 23:10 |
| kanzure | The discovery was made by splitting infrared light into two beams that each travel on a different length of silicon nanowire, called a waveguide. The two light beams became out of phase with one another, creating a push, or repulsive force, with an intensity that can be controlled; the more out of phase the two light beams, the stronger the force." | 23:10 |
| kanzure | Hong Tang, Nature Photonics | 23:10 |
| genehacker | oh saw that | 23:12 |
| genehacker | what could we use it for? | 23:12 |
| bkero | genehacker: Sorry, was fixing bike. They were making BJTs when I was there. | 23:12 |
| genehacker | what's a BJT? | 23:13 |
| kanzure | bipolar transistors? | 23:13 |
| bkero | Bipolar junction transistor | 23:13 |
| ybit | was reading about them last night and this morning | 23:13 |
| bkero | Except different. They were fitting more onto it. If I understood correctly it was a dual channel | 23:13 |
| ybit | that's pretty cool bkero | 23:13 |
| bkero | ...(can you make dual channel BJTs?) | 23:14 |
| genehacker | that's a chip | 23:14 |
| genehacker | almost | 23:14 |
| genehacker | it's a transistor that's good enough | 23:14 |
| bkero | Heh | 23:14 |
| bkero | Is there some faggy Harry Potter movie opening tonight? | 23:20 |
| genehacker | yup | 23:21 |
| drazak | "the linux version of windows explorer never crashes right?" | 23:21 |
| drazak | B[B[B[BB[B[B | 23:21 |
| drazak | what the fuck | 23:21 |
| genehacker | I said that | 23:21 |
| genehacker | with shame | 23:21 |
| drazak | you mean | 23:21 |
| drazak | firefox on linux? | 23:21 |
| genehacker | no I run vista | 23:22 |
| genehacker | windows explorer can crash now | 23:22 |
| drazak | lol | 23:22 |
| QuantumG | maybe he means Nautilus | 23:22 |
| drazak | it could crash in xp | 23:22 |
| QuantumG | and yes, it crashes | 23:22 |
| drazak | and 2000 | 23:22 |
| QuantumG | often in the exact same way as Explorer on windows | 23:22 |
| bkero | I should do my part and drive by with a giant HERMIONE DIES THIS TIME REALLY GUYS banner on my car. | 23:22 |
| genehacker | DO IT FAGGOT! | 23:22 |
| QuantumG | (for example, accessing an smb drive) | 23:22 |
| genehacker | oops that wasn't me talking | 23:23 |
| bkero | Explorer can crash looking at it funny. | 23:23 |
| genehacker | don't insult it | 23:24 |
| * drazak is making lockpicks out of bike spokes | 23:24 | |
| genehacker | that only makes it work | 23:24 |
| genehacker | why? | 23:24 |
| bkero | drazak: That's a waste. Bicycle spokes are perfect as welding rods. | 23:24 |
| genehacker | and technique? | 23:24 |
| drazak | bkero: I have like, 300 bike spokes | 23:24 |
| drazak | genehacker: files | 23:24 |
| bkero | drazak: What I hear you say is that you're going to weld a car together. | 23:25 |
| genehacker | flatten with hammer? | 23:25 |
| drazak | genehacker: flatten?! | 23:25 |
| drazak | I'm filing | 23:25 |
| drazak | them | 23:25 |
| genehacker | I don't think I understand how to turn bike spokes into lock picks | 23:25 |
| katsmeow-afk | speaking as someone who runs thru 200lbs of welding rod a yr, bike spokes do not make good welding rods | 23:27 |
| bkero | katsmeow-afk: What kind of welding are you doing with them, and are you using aluminum or steel? | 23:27 |
| katsmeow-afk | arc, dc, 7018 , steel | 23:28 |
| bkero | I always find that 7018 get a bunch of nasty pores when I weld | 23:29 |
| katsmeow-afk | clean the base metal better, lower the current, and no wind over the arc | 23:30 |
| katsmeow-afk | rust = pores | 23:30 |
| bkero | It's cold rolled, I hear that 7018 doesn't work very well on that to begin with. | 23:30 |
| katsmeow-afk | if the arc sounds sloppy, not crisp, you get flux inclusion pores | 23:30 |
| bkero | I'm only doing around 150a | 23:31 |
| katsmeow-afk | cold rolled isn't the best to be welding on with anything | 23:31 |
| katsmeow-afk | what size rod? | 23:31 |
| bkero | Whatever bicycle spokes are, hehe | 23:31 |
| katsmeow-afk | o | 23:31 |
| bkero | 1.85mm I think it is | 23:31 |
| katsmeow-afk | well, on 3/32 7018, i usually run 125amps, on 1/16 i run ~90 for tacking thin stuff | 23:32 |
| bkero | I'm usually tacking some sheets to RST | 23:32 |
| bkero | I can get a decent bead when joining 2 pieces of RST | 23:33 |
| katsmeow-afk | a 125amp bead on chamfered or slightly separated 1/4 plate will generally burn half way into it with a clean weld | 23:33 |
| katsmeow-afk | why don't you use real welding rod? | 23:33 |
| ybit | how much does taqman cost? | 23:33 |
| bkero | I can't afford it :/ | 23:34 |
| katsmeow-afk | i cannot afford the welds to break | 23:34 |
| bkero | My welder is 2 fucking transformers from microwaves | 23:34 |
| katsmeow-afk | ooohhh | 23:34 |
| bkero | a pair of vice grips, jumper cables, and welding gloves | 23:34 |
| splicer | ...and bicycle spokes | 23:35 |
| bkero | Are you calling me ghetto? | 23:35 |
| katsmeow-afk | mine is a 30 yr old Miller growlbox, with new fan, new diodes, new huge heatsink, new power relay on the main | 23:35 |
| bkero | So when you say turn down the current, yea, there's not a whole lot i can do there. :P | 23:36 |
| katsmeow-afk | hmm,, resistors in the primary | 23:38 |
| bkero | Right now I'm welding a bicycle jig together. | 23:38 |
| katsmeow-afk | i never got good welds on any 120v welder tho, hence mine is 240 mains | 23:38 |
| katsmeow-afk | here's it's new diode "block" : http://DesignerThinking.com/arcwelder.html | 23:39 |
| bkero | I went off this: http://www.instructables.com/id/Build-a-Microwave-Transformer-Homemade-Welder/ | 23:39 |
| katsmeow-afk | the circuit breaker in it i had added, i then subtracted | 23:39 |
| bkero | I actually have a 230A shunt wired through the ground so I could measure the amperage. | 23:40 |
| katsmeow-afk | still, take a lot of current over a lot of sine wave to keep a good arc, i wouldn't think you could on a 120v wall outlet | 23:40 |
| katsmeow-afk | microwaves are ~900 watts, so with 2 you get 1800 watts, i pop 40amp breaker on 240v line (9600 watts) | 23:42 |
| katsmeow-afk | course, that's after some time continuously welding at 150amps | 23:43 |
| katsmeow-afk | 3/32 rod doesn't take 150 amp well tho | 23:43 |
| bkero | Mine's around 30v | 23:44 |
| bkero | What do normal welders operate at? | 23:44 |
| katsmeow-afk | 60v open circuit, 40 operatig, depending on stuff | 23:45 |
| bkero | I measured operating, no idea what it is open circuit. | 23:45 |
| katsmeow-afk | the higher the voltage, the longer you can make the arc, which you might want to do occasionally | 23:46 |
| katsmeow-afk | and the easier it is to strike | 23:47 |
| bkero | 30v at 150 amps measured is 3kw, which isn't too bad as I understand it, compared to cheap harbor freight welders. | 23:47 |
| katsmeow-afk | a long arc is a good first pass on light rust, to blow it off before you make a serious pass with the rod | 23:47 |
| katsmeow-afk | ok, but how do you get 3kw outof 2 900watt transformers? | 23:48 |
| bkero | I tore up and rewound the transformers | 23:48 |
| katsmeow-afk | and how do you get 3000watts reom a 12v outlet? | 23:48 |
| bkero | 2 120v outlets | 23:48 |
| katsmeow-afk | o | 23:48 |
| bkero | in series | 23:48 |
| bkero | Well, the transformers are in series | 23:49 |
| * katsmeow-afk nods,, so you have 240, actually | 23:50 | |
| katsmeow-afk | might work just fine for small rod, lite welding | 23:51 |
| bkero | They're 35A lines too, so I think I'm well beneath that. | 23:51 |
| * katsmeow-afk nods | 23:51 | |
| bkero | I used it to learn how to weld :P | 23:51 |
| bkero | Only other thing I've used is a shittle little oxy thing | 23:51 |
| bkero | Oh yea, and welded some titanium for the frame of a solar challenge car. We covered the entire damn frame in a big plastic bag, purged it, and filled the entire thing with argon so we'd get clean welds. | 23:52 |
| katsmeow-afk | i have a patchwork of wire tween the arc welder and the house mains, the 12awg gets hot with fairly busy 130amp welding, the 10awg gets hot with continuous 130amp welding, and the 40amp breaker gets hot and kicks with constant 150amps | 23:52 |
| bkero | Go get yourself some 8 or 6 gauge. | 23:53 |
| katsmeow-afk | that costs, and the conduit is buried in concrete, and is too small for 8 | 23:53 |
| bkero | 8awg costs? | 23:54 |
| katsmeow-afk | this is summer, i don't do so much welding now anyhow, it's too hot with a jacket on out there | 23:54 |
| katsmeow-afk | 8awg copper costs,, i got 8awg and 00 Al laying around i can't get rid of | 23:55 |
| bkero | Nobody at the shop trusts my welder, so I get to do it at the side of the building. :/ | 23:55 |
| katsmeow-afk | i've felt 0000 al too hot to touch as SE cable to a *house* , i won't trust Al on heavy loads, especially outside fullmetal enclosures | 23:56 |
| katsmeow-afk | anyhoo, i need to go do things irl, bbl | 23:56 |
| bkero | My friend works at DANA in Modesto. Welds toyota truck frames | 23:56 |
| bkero | Later | 23:57 |
| bkero | Frame welds = hardcore | 23:57 |
| ybit | taqman? | 23:57 |
