nmz787kanzure: yeah i've looked at it, not in a week or so01:17
nmz787when i was just scanning it for resin links01:18
nmz787i found a UK company that has cheap resin, but shipping is crazy expensive01:18
@kanzureanyway, here's what i was reading on droplet storage:01:18
@kanzurehttp://diyhpl.us/~bryan/papers2/microfluidics/Simple,%20robust%20storage%20of%20drops%20and%20fluids%20in%20a%20microfluidic%20device.pdf01:18
nmz787something about their post office having an embargo for sending hazardous materials to the u.s.01:18
nmz787kanzure: do you have the accompanying autocad file?01:22
nmz787"An AutoCAD le of the actual device01:22
nmz787is included in the ESI (S7.dwg)."01:22
@kanzurenope not on me. ESI sounds like "electronic supplementary information".01:30
@kanzurei wonder if the zotero translators are able to pick up links to supplementary pdfs01:34
@kanzureif not, that's a rather serious omission.01:35
nmz787that would be nice01:35
nmz787they're often not pdfs though01:35
nmz787sometimes avi files, or in this case dwg01:35

nmz787is that really hplus related?13:01
nmz787not that i care13:01
chris_99am i right in thinking something like this plasmid http://www.addgene.org/22308/ would create GFP when inserted into yeast13:06
nmz787yes13:06
nmz787when galactose is added13:06
chris_99aha ok, cheers13:07
@kanzurenmz787: no, it's not. lapse of judgement.13:08
nmz787chris_99: http://en.wikipedia.org/wiki/Gal_operon13:10
chris_99thanks13:11
@kanzure"reminiscent of the case of Gordon & Breach v. American Institute of Physics and American Physical Society which started with the publication of articles on the cost of physics journals by H.H. Barschall"13:11

@kanzurehttp://www.insidehighered.com/news/2013/02/08/academic-press-sues-librarian-raising-issues-academic-freedom13:12
chris_99also i've been looking at this http://labs.fhcrc.org/gottschling/Yeast%20Protocols/ytrans.html the bottom protocol, so is it more or less a case of charging a 25uF cap, then discharging via a 200 ohm resistor to the cuvette13:12
@kanzurewhat is Edwin Mellen Press anyway?13:13
nmz787chris_99: electroporation has a few general methods13:13
nmz787the type of decay, a cap is exponential, is important and can be played with to give different results13:14
nmz787length of decay, voltage13:14
nmz787i was unsuccessful at transforming ecoli with a grill lighter piezo sparker13:14
chris_99mm, which is varied with the resistor i guess, and the initial charging voltage13:14
chris_99aha13:14
-!- sivoais [~zaki@unaffiliated/sivoais] has quit [Ping timeout: 260 seconds]13:15
nmz787but that was just based on the sparker putting out some average value i got from diybio13:15
nmz787and then changing the distance between electrodes13:15
nmz787so i must have been way off in some paramaeter13:15
nmz787it looks like that protocol wants SS-DNA, but I'm not sure if they mean ssDNA (single-stranded)13:17
chris_99oh i didn't notice that13:17
nmz787oh it was the first protocol13:17
nmz787with LiAc13:17
chris_99hmm, i've got a PSU that can do KV hopefully, i'd need to get the necessary caps / resistors though.13:18
nmz787" Give one pulse: V= 1.5kV, 25 F, 200 Ohms. Time should be ~4-5""13:18
nmz7874-5 minutes???13:18
nmz787i wonder if you could charge it with a piezo sparker13:18
nmz787they're around 10kv i think13:19
nmz787if i recall correctly13:19
archels1.5 kV over what electrode spacing?13:19
nmz787i'm bad when it comes to capacitors and charge and discharge13:19
nmz7870.2 cm13:19
chris_990.2cm cuvette13:19
nmz787chris_99: that means you could use a 0.1cm cuvette with 750V13:20
nmz787i'm not sure if you'd need to change the ohms though13:20
chris_99do http://www.addgene.org/ ship to residential addresses?13:20
nmz787prob not13:20
nmz787from what i heard recently you need to be non-profit or academic13:21
nmz787industrial users only have access to a subset of the dna13:21
archelsyou guys just need to build some Cockcroft-Walton voltage boosters13:21
chris_99mm, i got some caps to do that13:21
nmz787the professional electroporator i took apart used SCRs if that's worth anything13:21
archelschris_99: great, just add diodes =)13:22
chris_99is there anywhere else that would send plasmids13:22
@kanzuresciquest is asking for me to make a website with a picture of my product13:24
@kanzurei don't have a product. quick, someone make up a product!13:24
nmz787send openspectrometer13:25
@kanzureah good idea13:25
@kanzurethe deed has been done.13:26
archelsactually, I think laser printers have DC high voltage modules13:28
chris_99mm, i think your right13:30

@kanzureParahSail1n: hey did you happen to read the backlog with SphericalMouse yesterday?19:14
ParahSail1ni missed it19:14
SphericalMousehe's a terrible typist19:14
doclkanzure: any particular reason I should?19:15
@kanzuredocl: because putting transhumanist information in the same place increases the likelihood that contributors will maintain the information.19:16
ParahSail1nwhat was the backlog about, im on a different machine from usual19:17
doclmy theory is that multiple different sites/communities is good for diversity or some such. also my ego is more flattered at the thought of starting my own thing.19:18
@kanzureParahSail1n: SphericalMouse is interested in lab automation, and also has some experience with microfluidics.19:19
@kanzuredocl: what about just forking the repo? :)19:20
doclhmm. maybe. I'm using foswiki at the moment.19:20
doclwhat's diyhpluswiki.git in?19:20
@kanzurehave you ever used git?19:20
@kanzurewell, it's just a collection of files that can be rendered any way you please. i use ikiwiki.19:20
@kanzurehttp://diyhpl.us/wiki is the front-end19:20
@kanzurehttps://github.com/kanzure/diyhpluswiki is the git repo19:21
ParahSail1nSphericalMouse, thats cool19:21
doclI've played around a bit with github19:21
SphericalMouseindeed, what is your interest in the area?19:21
@kanzuredocl: the downside is that the default ikiwiki stylesheets don't look like mediawiki's monobook.css layout. i guess that might be one reason you might not use this.19:21

ParahSail1ni think it would be cool to have a cell sorter19:22
SphericalMousewhat kind of cells?19:23
ParahSail1nmammal i suppose19:23
ParahSail1nfacs is super expensive19:23
SphericalMousewhat do you want to sort based upon?19:24
-!- wizrobe [~aserid@c-76-23-254-105.hsd1.ct.comcast.net] has joined ##hplusroadmap19:24
ParahSail1nif i had one, im sure i could think of a few things to do19:24
SphericalMousewell, there are different ways to sort things19:25
doclfor now, the wiki is at http://bettercryonics.com/BetterCryonics19:25
SphericalMousebead/surface binding, dielectrophoresis, electrophoresis, size based, density based19:27
SphericalMouseblah blah19:27
ParahSail1nmost of the sorting id want to do would probably be based on fluor markers19:27
SphericalMouseurff19:28
ParahSail1nit would be nice to just have a flow cytometer to take measurements of population even19:29
SphericalMouseI suppose you could flow things at low density down a y channel and have some force push things from one side to another19:29
SphericalMouseoh, thats pretty simple, as things go19:29
SphericalMouseinverted flourescent microscope with camera19:30
ParahSail1ni did some experiments on facscanto, but it would be pretty cool to be able to afford one19:30
SphericalMousewhat do you have?19:31

ParahSail1nwell i was a grad student for a while doing wet lab, now i'm kinda out of that area19:33
SphericalMousewhat equipment or facilities do you have access to?19:34
ParahSail1na pirate version of the agilent bioanalyzer would be cool too, for qc of ngs library prep19:34
ParahSail1nnothing at the moment19:34

doclI don't mind19:35
SphericalMousehow much are you willing to spend?19:36
ParahSail1nit depends on the upside?19:37

SphericalMousesay you could take pictures of cells, extract the fluorescence level, and look at size and shape? would that be what you want?19:38
nmz787howdy19:38
ParahSail1nwell, i could probably find a good deal on that sort of stuff on slapsale19:39
SphericalMouseon what?19:40
ParahSail1nfluorescence microscopy19:41
nmz787hey a site that isn't ebay!19:41
nmz787any ideas on how to hook up a fridge peltier to act as a still chiller?19:41
SphericalMouseeverclear is pretty cheap19:42
SphericalMousewell, what would your overall budget be?19:44
nmz787this looks pretty nice http://www.slapsale.com/item_desc.aspx?itemid=6360119:45
nmz787hm, maybe not19:46
nmz787sorry19:46
SphericalMouseunfortunately, that is not a brand of fluorescent microscope i am familiar with19:46
nmz787hey there are a few good looking deals, ParahSail1n is this all local pickup?19:47
ParahSail1nnmz787, yes19:47
nmz787this scope is pretty nice if the price stays low http://www.slapsale.com/item_desc.aspx?itemid=6370519:48
SphericalMouseusually you want an inverted microscope19:49
-!- docl [~docl@unaffiliated/docl] has quit [Quit: leaving]19:50
SphericalMouseespecially for micofluidics19:50
nmz787why?19:50
SphericalMousevarious accesibility reasons. often there will be plumbing, which is easier to deal with if ti comes out the top, but then it bangs into the objectives of an upright scope19:51
nmz787huh, why don't people just make manifolds that have sideports?19:51
nmz787like a CPU socket19:52
SphericalMouse~lolzz~19:52
nmz787where an arm comes and closes over the top19:52
nmz787compresses down19:52
SphericalMouseoftne pdms microfluidics will have a thin and thick side, and a scope wont be able to image through the thick side, andyou want the thin side down19:53
-!- augur [~augur@208.58.5.87] has joined ##hplusroadmap19:54
SphericalMouseevery fluid connection i have ever seen comes in through the top or bottom, never the side19:54
nmz787weird19:54
SphericalMouseconsequence of manufacturing19:54
SphericalMouseand geometry19:55
JayDuggerWould you have ullage problems without gravity draining the channel?19:55
ParahSail1nyeah ive only seen vias at top and bottom19:55
ParahSail1ngravity can't make enough pressure to make flow through microchannel19:55
JayDuggerFair enough.19:56
SphericalMouseyou can have gravity driven flow issues, typially it is low compared to other forces, but you can see it if you're not careful19:56
SphericalMousejust blance your inlet ant outlet heights19:56
SphericalMousegoddamn wine19:56
SphericalMouseI would use about 5-10 psi do drive fluid through microchannels, internet says 1 psi is a delta of 27 inches of water19:58
SphericalMousei have seen people use sliding vials on rails as a pressure source though20:05
nmz787i think i saw something like that not too long ago20:07
SphericalMousei alsways used a gas line with a tunable regulator, but the rail will work as well, probably more accurate, but getting 5 psi would require a 10 footish rail20:08

@kanzureit looks like mendeley might be interested in donating rule 34 relevant artwork for launching springerkink.com22:07
@kanzureyashgaroth: it will be glorious22:08
yashgarothnot even sure what to say to that22:09
Juulkanzure, storage space? i have a 4 tb harddrive but only about 15% downloaded22:10
@kanzurewell i'm just tired of not having access to springerlink.com22:10
Juulit's been taking longer than it should due to some suspicious network issues22:10
Juul(possibly trolls but could be stupidity)22:10
Juulbasically someone came in and hard reset two routers22:11
yashgarothdo you share the routers with people?22:13
yashgarothif you overloaded the router and someone else using it got pissed off and reset it22:13
yashgaroththen again I have no idea what your setup is22:15
Juulyashgaroth, i rate limited everything. but yeah it was in a shared space. we've been getting trolled though, so it may be trolls at work22:27
Juulthey also fucked the network by doing that since it created a rogue dhcp server22:28
