| kanzure- | the alarm sound could be fixed by long headphones | 00:00 |
|---|---|---|
| kanzure- | a headphone jack shouldn't be too hard to integrate on to it | 00:00 |
| kanzure- | although maybe it would be better if the battery discharges an electric shock | 00:00 |
| ybit | " The Elite has a snooze button, audible and vibrating alarms, is water-resistant,..." | 00:16 |
| ybit | sweet. | 00:16 |
| ybit | now what file format is the data stored in... :) | 00:25 |
| kanzure | http://www.s-ten.eu/scadaonweb/NOTE-units/2002-08-05/NOTE-units.html RDF vocabulary for physical properties, quantities and units | 00:39 |
| kanzure | meh | 00:39 |
| kanzure | http://www.w3.org/TR/mathml-units/ | 00:39 |
| kanzure | http://mathdom.sourceforge.net/ bah doesn't implement the MathML-units subset. | 00:42 |
| kanzure | this sounds like a terrible idea: http://www.aclevername.com/articles/python-webgui/ creating python apps with HTML rendering engines | 00:43 |
| kanzure | er, what? http://empathy.sympy.org/ | 00:45 |
| kanzure | http://3.bp.blogspot.com/_Y5scPLmSvG0/SYnjsGNXnBI/AAAAAAAAAHA/u7QCC2mhzl8/s1600-h/Picture+2.png | 00:45 |
| kanzure- | genehacker: have a few minutes? | 02:01 |
| genehacker | sure | 02:01 |
| genehacker | what is it | 02:01 |
| kanzure- | ok, one moment. | 02:01 |
| kanzure- | basically I have an equation and a diagram and I'm wondering how this author got from one to the other | 02:02 |
| genehacker | what class? | 02:03 |
| genehacker | is it diff-eq? | 02:03 |
| genehacker | you might consider going to tutoring | 02:04 |
| kanzure | http://heybryan.org/books/papers/campbell-dissertation-diagram-thingy.png | 02:04 |
| kanzure | first of all, why would you have 1/k for a spring? | 02:05 |
| kanzure | if k is the spring constant of the spring | 02:05 |
| genehacker | because the spring is acting against it? | 02:07 |
| kanzure | wouldn't that be subtractive? | 02:07 |
| genehacker | don't know | 02:08 |
| kanzure | does the shape of those equations make sense? | 02:08 |
| kanzure | *do the shapes of those equations | 02:08 |
| genehacker | seems like you guys have made some progress though | 02:08 |
| kanzure | ? | 02:09 |
| genehacker | what software is this in? | 02:09 |
| kanzure | lisp | 02:09 |
| kanzure | this was from cambell's July 2000 dissertation | 02:09 |
| kanzure | campbell's | 02:10 |
| kanzure | gah. /me fails at typing tonight | 02:10 |
| kanzure | what's the effect of increasing the radius of the gear? | 02:20 |
| genehacker | more radial displacement of rod | 02:20 |
| genehacker | err less? | 02:21 |
| genehacker | forgot | 02:21 |
| kanzure | ? | 02:21 |
| genehacker | can't think now | 02:21 |
| kanzure | because in this case the theta of a dial-doohicky is being changed by 1/r where r is the radius of the gear | 02:21 |
| kanzure | so a larger radius is going to make a smaller impact. | 02:21 |
| kanzure | just want to make sure this makes sense. so far it doesn't sound like it. | 02:21 |
| genehacker | use geometry | 02:24 |
| kanzure | huh? | 02:27 |
| kanzure | yay. campbell's dissertation included source code at the end. | 02:28 |
| genehacker | rack displacement= arclength | 02:29 |
| kanzure | oh? | 02:29 |
| genehacker | =theta*r | 02:29 |
| kanzure- | so I like how these papers are written, by campbell I mean | 03:10 |
| kanzure- | "for more information on this method, please see Campbell 1998b" | 03:10 |
| kanzure- | *campbell 1998b* <same text as in the dissertation, doesn't explain a thing> | 03:10 |
| genehacker | so are there any books of chemicals with reactions on how to make them | 03:51 |
| genehacker | I want a chemical microfactor | 03:51 |
| genehacker | y | 03:51 |
| katsmeow-afk | i want 10 gallons of anhydrous ammonia | 04:09 |
| kanzure- | I want a meth lab that dissolves within the presence of cop sweat. | 04:16 |
| kanzure- | wait, I don't actually know anybody who has a meth lab | 04:16 |
| kanzure- | what is the type of person who makes a meth lab anyway? | 04:17 |
| katsmeow-afk | profit oriented, a real go getter, someone who takes calculated risks | 04:17 |
| katsmeow-afk | bank presidents, perhaps | 04:17 |
| kanzure- | is there a distribution network for illegal meth lab equipment or something? | 04:17 |
| katsmeow-afk | umm, i doubt it, but possibly | 04:18 |
| genehacker | heh | 04:18 |
| kanzure- | are they that organized? | 04:18 |
| katsmeow-afk | there's illegal nets for everything else | 04:18 |
| kanzure- | guess so | 04:18 |
| genehacker | let's not do meth production | 04:18 |
| katsmeow-afk | i dunno what i'd use meth for, actually | 04:18 |
| kanzure- | just wondering how they do it. | 04:18 |
| katsmeow-afk | i do have a use for the ammonia tho | 04:18 |
| genehacker | they don't do it very carefully | 04:19 |
| genehacker | think harvesting lead batteries for sulfuric acid | 04:19 |
| genehacker | that sort of thing | 04:19 |
| katsmeow-afk | atm, the lead may be more profitable | 04:19 |
| katsmeow-afk | also more restricted by EPA | 04:19 |
| katsmeow-afk | if you pour out a lead acid battery, they get your forlead contamination, not the acid | 04:20 |
| genehacker | I think I might teach myself O chem | 04:20 |
| genehacker | over the summer | 04:20 |
| katsmeow-afk | i wanna make a couple "frosty balls", then praps improve them from that point | 04:21 |
| kanzure- | organic chem? | 04:21 |
| genehacker | the heat based fridge thing? | 04:22 |
| genehacker | yeah | 04:22 |
| katsmeow-afk | water absorber fridge, yeas | 04:22 |
| genehacker | how else am I going to figure out how to synthesize 3,4-(methylenedioxy)acetophenone | 04:22 |
| genehacker | can't find that much info about it on google | 04:23 |
| kanzure- | graph grammars. | 04:23 |
| katsmeow-afk | *if* the things work as advetised, and i can figure a btu rating for them, then how to keep , esentially but not really, one in the solar recycler, and one in duty cooling me | 04:23 |
| kanzure- | genehacker: or retroactive synthesis | 04:23 |
| genehacker | yeah automatic design of microreactors would be great | 04:23 |
| kanzure- | no, I mean of chemical reactions | 04:23 |
| kanzure- | this is like the perfect application | 04:24 |
| genehacker | as I said I want a chemical factory that can make anything | 04:24 |
| kanzure- | lemme see if anyone has written an organic chemistry graph grammar | 04:24 |
| genehacker | well you know the chemical reactions that take place you just use standard reactors | 04:24 |
| kanzure- | huh? | 04:24 |
| kanzure- | did you mean to include an "if" in there? | 04:25 |
| katsmeow-afk | i am thinking a mist of water falling thru the ammonia, and the sent to the solar furnace to get the ammonia out, which is condenced and sent back to the evaporator, with a tank of water as the "flywheel" for the thing | 04:25 |
| genehacker | solar cooling systems are pretty weird | 04:25 |
| genehacker | also ammonia is a basic chemical it's a must for my a chemical microfactory | 04:26 |
| katsmeow-afk | with no sun for a few days, there's still a tank of water and enough ammonia, and with sun or other heat source, the tank of water is processed to remove the ammonia | 04:26 |
| kanzure- | heh. sciXML | 04:27 |
| genehacker | you found one? | 04:27 |
| kanzure- | not yet | 04:28 |
| kanzure- | but maybe you could just make the grammar rules or something | 04:30 |
| kanzure- | since organic chemistry has only like 21 main rules | 04:30 |
| kanzure- | "if you see this, then blah" | 04:30 |
| genehacker | cool | 04:31 |
| genehacker | have you taken O chem? | 04:31 |
| kanzure- | no, but I've read a few books | 04:31 |
| genehacker | http://www.rsc.org/Publishing/Journals/LC/article.asp?doi=b822106e | 04:31 |
| genehacker | hehehehehe | 04:31 |
| genehacker | alkaloid purification | 04:31 |
| genehacker | alkaloids generally tend to have certain effects on humans | 04:32 |
| genehacker | http://www.rsc.org/Publishing/Journals/LC/article.asp?doi=b901790a | 04:32 |
| kanzure- | odd, nobody has done one yet | 04:32 |
| genehacker | tiny distilation column | 04:33 |
| genehacker | 1write one | 04:33 |
| genehacker | 2.??? | 04:33 |
| genehacker | 3. profit! | 04:33 |
| kanzure- | well we could publish it and act like it's important | 04:34 |
| kanzure- | or just use it. | 04:34 |
| genehacker | what would this graph grammar allow us to do? | 04:35 |
| genehacker | explain what a graph grammar is | 04:35 |
| kanzure- | well, do you know the basic organic chemistry reaction mechanisms? | 04:35 |
| kanzure- | there's like 20 of them, right? | 04:35 |
| genehacker | no | 04:35 |
| kanzure- | er? | 04:35 |
| kanzure- | no you don't know them, or no there's not 20? | 04:35 |
| genehacker | I don' t know them | 04:35 |
| kanzure- | http://en.wikipedia.org/wiki/Organic_reaction | 04:35 |
| genehacker | I'll ask my friend who is taking ochem | 04:35 |
| genehacker | tomorrow | 04:36 |
| kanzure- | the basic types are: | 04:36 |
| kanzure- | addition, elimination, substitution, pericyclic, rearraangement, redox | 04:36 |
| kanzure- | *rearrangement | 04:36 |
| kanzure- | so the idea is to automatically come up with a sequence of steps to take some basic chemicals/structures | 04:36 |
| kanzure- | and transform them into some target compound | 04:36 |
| kanzure- | right? | 04:36 |
| kanzure- | using those reaction types. | 04:36 |
| kanzure- | example: http://en.wikipedia.org/wiki/Substitution_reaction | 04:37 |
| kanzure- | see how there's a left-hand side and a right-hand side? | 04:37 |
| kanzure- | that's basically what we encode into the graph grammar rules | 04:37 |
| genehacker | given a compound, given some basic chemicals like CO, CO2, H, B, N? | 04:37 |
| kanzure- | or something, yeah | 04:37 |
| kanzure- | one moment. let me bring in an organic chemist. | 04:38 |
| kanzure- | blah. nevermind. | 04:41 |
| kanzure- | I think that most people are not interested in building up from basic elements and simple compounds because it would be too many steps | 04:46 |
| kanzure- | but if you're designing a microfluidic system automatically or something | 04:46 |
| kanzure- | then it becomes much easier. | 04:46 |
| genehacker | heat transfer is somewhat easier in microfluidic systems I think too | 04:47 |
| genehacker | yeah that's the point | 04:47 |
| genehacker | that's why it | 04:47 |
| genehacker | 'd be microfluidic | 04:47 |
| genehacker | maybe a bit bigger than microfluidic for some slightly decent production rate | 04:48 |
| kanzure- | I saw a full chemical reaction plant in bondgraph form a few months ago in a ppaer | 04:48 |
| kanzure- | paper | 04:48 |
| kanzure- | was pretty neat | 04:48 |
| kanzure- | http://heybryan.org/books/papers/bondgraphs/Bond%20graph%20modelling%20for%20chemical%20reactors.pdf | 04:48 |
| genehacker | wonder if we could make a machine that turns garbage into useful products given energy | 04:53 |
| kanzure- | oh crap, wrong link | 04:53 |
| kanzure- | try this one: http://heybryan.org/books/papers/bondgraphs/Automatic%20Generation%20of%20Bond%20Graph%20Models%20of%20Process%20Plants.pdf | 04:53 |
| kanzure- | hi fenn. | 05:06 |
| ybit | who's read the 'landmark' paper by fritz? "Translating Biomolecular Recognition into Nanomechanics " | 05:17 |
| kanzure | link or it didn't happen. | 05:17 |
| ybit | http://www.sciencemag.org/cgi/content/abstract/288/5464/316 | 05:19 |
| kanzure | "Hybridization of complementary oligonucleotides shows that a single base mismatch between two 12-mer oligonucleotides is clearly detectable. " | 05:22 |
| kanzure | eh? | 05:22 |
| ybit | was referenced in: "Nanomechanical biosensors: a new sensing tool " http://ezproxy.una.edu:2062/science?_ob=MImg&_imagekey=B6V5H-4HK5SGC-1-M&_cdi=5787&_user=7166845&_orig=search&_coverDate=03%2F31%2F2006&_sk=999749996&view=c&wchp=dGLbVtb-zSkWA&md5=4b121d7c045bc7c383f075ad84271dda&ie=/sdarticle.pdf | 05:22 |
| ybit | yeah, i haven't figured out how to link properly from within sciencedirect | 05:22 |
| kanzure | heh, you're at home? | 05:23 |
| kanzure | you basically just replace ezproxy.una.edu:2062 with sciencedirect.com | 05:23 |
| ybit | http://dx.doi.org/10.1016/j.trac.2005.09.006 | 05:23 |
| kanzure | yep, my replacement scheme worked | 05:23 |
| ybit | sd has a 'cite or link using doi' | 05:23 |
| ybit | ah, yes | 05:24 |
| ybit | that works too | 05:24 |
| kanzure | looks like this is just "sense a chemical reaction by using an AFM tip that has something special attached to it" | 05:24 |
| kanzure | "high-throughput platforms using arrays of cantilevers have been developed for simultaneous measurement and read-out of hundreds of samples" | 05:25 |
| kanzure | er, how does that look | 05:25 |
| * ybit needs to familiarize himself with bibliography tools | 05:26 | |
| ybit | what about it? | 05:26 |
| kanzure | zotero is what I've been using recently | 05:26 |
| kanzure | just wondering how they are able to squeeze so many cantilevers together | 05:27 |
| kanzure | I guess they can just shine a laser over the surface of cantilevers or something | 05:27 |
| kanzure | and read them one at a time (in rapid succession) | 05:27 |
| kanzure | but that's cheating | 05:27 |
| kanzure | because you need continuous read-out | 05:27 |
| kanzure | oh. a nano-array of nanocantilevers. bah. | 05:33 |
| kanzure | fenn: http://heybryan.org/books/papers/Guiding%20conceptual%20design%20through%20behavioral%20reasoning%20-%20Welch%20-%20Dixon%20-%201994.pdf | 07:02 |
| kanzure | Hi kardan. | 07:03 |
| kanzure | huh. "directed dependencies". (pg 4) | 07:05 |
| kanzure | seems to restrict the type of analytical equation derived from a design though | 07:05 |
| kanzure | so these partials then define how to construct the equation. a positive directional dependency would imply that there's a positive correlation (i.e., 1*k), whereas a negative directional dependency would imply 1/k | 07:06 |
| kanzure | but then what about terms that need to be added or subtracted? | 07:06 |
| kanzure | I think this is my favorite arxiv feed: http://arxiv.org/list/physics.ins-det/recent | 08:16 |
| kanzure | http://arxiv.org/list/physics.ins-det/0610?show=32 | 08:19 |
| kanzure | (just getting the URL voodoo magic right) | 08:19 |
| kanzure | heh, AFM + MRI. /me likes physics.ins-det | 08:31 |
| kanzure | Experimental Study of the Acoustic Field Generated by a 50 MeV Electron Beam in Water | 08:48 |
| kanzure | Hi cis-action_ | 15:02 |
| cis-action_ | hi! | 15:03 |
| cis-action_ | what's up, kanzure | 15:06 |
| kanzure | cis-action_: microorganism playlist http://www.youtube.com/view_play_list?p=B16E0C8E552629DE | 15:06 |
| cis-action_ | I have watched a couple | 15:06 |
| kanzure | already? how's that | 15:06 |
| cis-action_ | I am curious what the average hobbyist microscopist setup costs | 15:07 |
| kanzure | "not much" | 15:07 |
| kanzure | doesn't intel give away these cheap little plastic microscopes or something? | 15:07 |
| kanzure | the webcam-microscopes | 15:07 |
| cis-action | back up? gah, this coffeeshop wifi is junky | 15:15 |
| kanzure | cis-action: maybe you could work us diybioers a good deal for used microscopes? | 15:20 |
| cis-action | yeah. that would be good | 15:21 |
| kanzure | genehacker: holy shit. have you been going to the ion channel journal club? | 15:28 |
| myelinzar | need to steal the utex.org database | 17:47 |
| myelinzar | http://heybryan.org/books/papers/channeljc/ | 17:51 |
| myelinzar | Measurement of Cantilever Displacement Using a Compact Disk http://heybryan.org/books/papers/Measurement%20of%20Cantilever%20Displacement%20Using%20a%20Compact%20Disk.pdf | 17:52 |
| myelinzar | Monitoring of an atomic force microscope cantilever with a compact disk pickup http://heybryan.org/books/papers/Monitoring%20of%20an%20atomic%20force%20microscope%20cantilever%20with%20a%20compact%20disk%20pickup.pdf | 17:52 |
| myelinzar | http://www.cs.cmu.edu/afs/cs/project/cadet/ftp/docs/CADET.html | 17:59 |
| myelinzar | er? | 17:59 |
| cis-action_ | Hey guys, let's invent or appropriate a new phrase | 18:30 |
| cis-action_ | the goal is to post a good suggestion here: http://www.michaeleisen.org/blog/?p=296#comments | 18:30 |
| cis-action_ | consider http://en.wikipedia.org/wiki/Homeorhesis, http://en.wikipedia.org/wiki/Chreod, and http://en.wikipedia.org/wiki/Phase_space | 18:31 |
| cis-action_ | more background: http://en.wikipedia.org/wiki/Spatiotemporal_gene_expression | 18:31 |
| cis-action_ | also see http://web.mit.edu/jakebeal/www/Publications/biocompile.pdf - very interesting! | 18:31 |
| kanzure | plastic | 19:11 |
| cis-action_ | plastic? | 19:11 |
| kanzure | yes. | 19:11 |
| cis-action_ | I was thinking perhaps we could take an analogy from music. | 19:11 |
| kanzure | Plasticity - In physics and materials science, plasticity describes the deformation of a material undergoing non-reversible changes of shape in response to applied forces | 19:12 |
| kanzure | although in this case it is somewhat reversible | 19:12 |
| kanzure | cis-action_: so, apparently it is possible to make a microscope out of a drop of water and a paper clip | 19:13 |
| kanzure | but it has only 2x magnification | 19:13 |
| kanzure | http://bizarrelabs.com/micro.htm | 19:14 |
| kanzure | also see the "table top model" | 19:14 |
| cis-action_ | neat | 19:14 |
| cis-action_ | would a pinhole also work? | 19:14 |
| kanzure | a pinhole does not magnify. | 19:15 |
| cis-action_ | nevermind. | 19:15 |
| kanzure | heh, tested it? | 19:15 |
| cis-action_ | uh... what's the difference between focusing and magnification? | 19:15 |
| kanzure | focusing is where light converges on to a single point. you don't want that to happen when you are magnifying | 19:19 |
| kanzure | http://www.rockcastle.org/activities/watermagnifier/watermagnifier.html | 19:20 |
| kanzure | a superhydrophobic surface with a very tiny drop of water would be the best magnifier methinks | 19:21 |
| kanzure | I've been trying to figure out what the largest hysteresis angle is for a superhydrophobic surface and a drop of water | 19:21 |
| kanzure | To use a water-drop lens on something that is not flat on a desk or table, you can make a little loop in a thin wire bent around a stout nail to make a loop. In this loop, you can put a drop of water. You can "waste" many such lenses until you get one whose curvature is just about right. | 19:22 |
| kanzure | "broth lens" heh | 19:22 |
| kanzure | also try it with the water on saran wrap | 19:25 |
| kanzure | water-drop projector, bwahahah | 19:28 |
| kanzure | cis-action_: this is sufficiently cool to warrant your attention. | 19:30 |
| kanzure | http://heybryan.org/books/papers/Water-drop%20projector.pdf | 19:30 |
| kanzure | http://heybryan.org/books/papers/Water-drop%20projector.pdf | 19:32 |
| kanzure | hm. so if you put multiple drops of water in a row, would that increase the magnification? | 19:32 |
| kanzure | hah, yay for halfbakery | 19:36 |
| kanzure | http://www.halfbakery.com/idea/Fly_20eye_20water_20lens | 19:36 |
| kanzure | http://www.technologyreview.com/computing/21449/?a=f An adjustable-focus lens made of two drops of water could be used in small cameras. | 19:36 |
| xp_prg | kanzure did you know blender can export collada format? | 19:38 |
| kanzure | collada is what? | 19:45 |
| kanzure | images of droplet magnifiers | 19:48 |
| kanzure | http://www.flickr.com/photos/lordv/sets/72057594101162264/ | 19:48 |
| fenn | but zone plates do | 20:02 |
| fenn | guh | 20:02 |
| fenn | a pinhole does not focus, it makes an image cone | 20:03 |
| xp_prg | collada is a 3d file format | 20:03 |
| genehacker | so I asked my friend who's taking ochem | 20:04 |
| genehacker | about the reactions | 20:04 |
| genehacker | she says there's about 15 | 20:04 |
| fenn | i think the problem with lots of steps in synthesis is that you have to purify each step or else you end up with a bunch of side reaction junk at the end | 20:05 |
| genehacker | btw how sensitive is something that can measure parts per billion concentrations? | 20:06 |
| kanzure | that doesn't sound like much.. considering avogadro's number. | 20:06 |
| genehacker | oh well | 20:07 |
| fenn | werent they making some moon telescope with mostly frozen mercury rotating slowly so as to form a parabola? | 20:07 |
| kanzure | so why don't I see any "capillary tube lens arrays" of droplets? | 20:07 |
| genehacker | anyway, found a cool microfluidic device that we could have that one guy make | 20:07 |
| fenn | ppb is pretty useful for lots of stuff | 20:07 |
| genehacker | a microfluidic gas chromatograph | 20:08 |
| kanzure | ppb? | 20:08 |
| fenn | kanzure: the droplet array would never work | 20:08 |
| kanzure | why's that | 20:08 |
| genehacker | droplet array has been done before | 20:08 |
| kanzure | genehacker: not a 2D array | 20:08 |
| kanzure | a 1D array | 20:08 |
| fenn | too hard to control the focal length | 20:08 |
| fenn | a 1d array? | 20:08 |
| genehacker | a 2d array | 20:08 |
| kanzure | well I'm talking about a 1D array | 20:08 |
| kanzure | ooooooooooooooooooooooooo | 20:08 |
| fenn | the oil lens thing is neat though | 20:09 |
| genehacker | liquid microlens arrays | 20:09 |
| kanzure | genehacker: have you ever used a one-dimensional array? | 20:09 |
| genehacker | no | 20:09 |
| kanzure | god programming classes suck these days | 20:09 |
| genehacker | that sort of array? | 20:10 |
| genehacker | yeah definately | 20:10 |
| kanzure | same thing | 20:10 |
| genehacker | ok so why are you interested in microlenses? | 20:10 |
| genehacker | ppb thing I was talking about was a microfluidic CO2 sensor btw | 20:11 |
| fenn | where are you going to be finding ppb of CO2? | 20:11 |
| genehacker | car exhaust is what they proposed | 20:12 |
| fenn | ummm | 20:13 |
| fenn | car exhause is like 50% CO2 | 20:13 |
| genehacker | yeah or something like that | 20:13 |
| genehacker | oxygen or something | 20:13 |
| genehacker | forgot | 20:13 |
| fenn | water | 20:13 |
| fenn | nitrogen | 20:13 |
| genehacker | it was in this book | 20:14 |

| kanzure | http://laser.physics.sunysb.edu/~scott/liquid-lens/ | 20:16 |
| genehacker | oh, almost forgot | 20:16 |
| genehacker | so I was thinking about that cheap maskless lithography gene synthesis method that put a projector on a microscope | 20:17 |
| genehacker | so the problem with that is alignment | 20:17 |
| genehacker | to get the chemicals on the microscope slide, you'd have to move the microscope out of focus or the microscope slide from under the microscope | 20:18 |
| genehacker | this means we'd have to align it each time | 20:19 |
| genehacker | which is hard | 20:19 |
| kanzure | that's what the guys did for the microfluidics version | 20:19 |
| genehacker | huh? | 20:19 |
| kanzure | they had this turnable thingy doohickey that rotated the specimen out of the field of view | 20:19 |
| genehacker | that's why some sort of thing that sits on the slide and dispenses chemicals would be nice | 20:19 |
| genehacker | link to turn table thing? | 20:20 |
| ybit | http://www.google.com/hostednews/afp/article/ALeqM5j_fD9Hyb2yHGiXZSFRhpu9BMvWCw | 20:20 |
| ybit | BEIJING (AFP) — Officials in a county in central China have been told to smoke nearly a quarter million packs of locally made cigarettes annually or risk being fined, state media reported. | 20:21 |
| ybit | The Gong'an county government in Hubei province has ordered its staff to puff their way through 230,000 packs of Hubei-produced cigarette brands a year, the Global Times said. | 20:21 |
| kanzure | genehacker: they didn't mention it in the paper other than that they were using it | 20:21 |
| genehacker | argh | 20:21 |
| genehacker | in all these DNA synthesis papers | 20:21 |
| genehacker | they say standard DNA synthesizer or something like that | 20:22 |
| kanzure | it's phosphoramidite synthesis | 20:23 |
| kanzure | did you look at my paper collection? | 20:23 |
| kanzure | http://heybryan.org/mediawiki/index.php/DNA_synthesizer | 20:23 |
| kanzure | http://heybryan.org/books/papers/microfluidics/synthesizer/ | 20:23 |
| kanzure | oops, last link was wrong | 20:24 |
| kanzure | http://heybryan.org/books/papers/microfluidics/synthesis/ | 20:24 |

| fenn | supposedly you can actually buy a webcam with one of these lenses in it | 20:24 |
| genehacker | http://www.azonano.com/sale.asp?saleID=188 | 20:25 |
| fenn | but it looks pretty straightforward to make | 20:25 |
| kanzure | right | 20:25 |
| kanzure | heh, Dune. | 20:25 |
| genehacker | so we need a flow cell reaction chamer | 20:25 |
| genehacker | *chamber | 20:25 |
| fenn | also check out 'origami optics' (not what you think) | 20:26 |
| kanzure | http://www.popsci.com/files/imagecache/article_image_large/files/articles/origami-lens-1a.jpg | 20:27 |
| kanzure | I do not understand | 20:27 |
| kanzure | what's with the black gloves? | 20:27 |
| kanzure | has there been any study of positional control/stability of falling drops of water from a dripping faucet (etc.)? | 20:28 |
| kanzure | if you have two or more droplets in mid-air on the same axis, lasers might be interesting in that scenario somehow | 20:28 |

| genehacker | electrostatics | 20:29 |
| fenn | not related to ... whatever it is you're doing, but it's still cool | 20:30 |
| genehacker | how do we make the nucleotides for DNA synthesis? | 20:32 |
| genehacker | nevermind | 20:32 |
| genehacker | it's on your page | 20:32 |
| genehacker | found it but don't really understand it | 20:33 |
| genehacker | or at least I think I understand it | 20:33 |
| genehacker | ooops | 20:35 |
| genehacker | I think I found it | 20:35 |
| kanzure | http://www.flickr.com/photos/22652313@N03/3325505361/ | 20:41 |
| kanzure | now just look at it through the other way | 20:41 |
| genehacker | so what are liquid lenses good for? | 20:43 |
| genehacker | could one make some sort of flat binoculars with them, make glasses that are really binoculars | 20:44 |
| kanzure | haha, captain curiosity | 20:44 |

| kanzure | http://www.projectlabs.com/htmldocs/straw.htm straw chromatography | 20:45 |
| genehacker | hmmm | 20:46 |
| genehacker | could we seperate proteins and stuff? | 20:46 |
| kanzure | with the spiral filter on a nanometer scale, yes | 21:13 |
| kanzure | or with SDS-PAGE | 21:13 |
| kanzure | http://www.portaldoors.org/ | 21:14 |
| kanzure | they want to collaborate with me | 21:14 |
| kanzure | not sure what they do .. | 21:22 |
| kanzure | "The image dissector was invented by Philo Farnsworth, one of the pioneers of electronic television, in 1927" | 22:00 |
| kanzure | haha! image DISSECTOR! | 22:00 |
| -!- davidsjo is now known as johndace | 22:44 | |
| kanzure- | Hi johndace | 22:44 |
| -!- johndace is now known as davidsjolteon | 22:47 | |
| kanzure- | heh, jolteon. | 22:52 |
| kanzure- | so I think you could make an image sensor with an array of biotinylated light-gated ion channels. at least for black-and-white image sensors. | 22:57 |
| kanzure- | genehacker: you might want to consider bacteriorhodopsin as playing a role in gene synthesis. | 23:25 |
| genehacker | what? | 23:25 |
| genehacker | you know you can glue bacteria to microchannels and use them as pumps? | 23:25 |
| kanzure- | eh? | 23:25 |
| kanzure- | I haven't seen that yet | 23:25 |
| kanzure- | ref? | 23:25 |
| genehacker | in pressure driven microfluidics | 23:26 |
| genehacker | in the engineering library | 23:26 |
| genehacker | btw, I'm looking for some documentation on a piece of software called working model | 23:30 |
