21:15 <nmz787> john_cephalopoda: I wouldn't mind writing up something

21:16 <Noxz> FIB = ?

21:16 <Noxz> focused ion beam?

21:16 <nmz787> john_cephalopoda: do you think it should be individual sections/pages? Like one for spin-coating, one for focusing the FIB, one for developing the PMMA? Or everything on one page, with sections for each?

21:16 <nmz787> Noxz: yes

21:16 <Noxz> what is the ion source?

21:16 <nmz787> gallium

21:16 <Noxz> oh, neat

21:17 <Noxz> "In a gallium LMIS, gallium metal is placed in contact with a tungsten needle, and heated gallium wets the tungsten and flows to the tip of the needle, where the opposing forces of surface tension and electric field form the gallium into a cusp shaped tip called a Taylor cone. The tip radius of this cone is extremely small (~2 nm). The huge electric field at this small tip (greater than 1 x 108 volts per centimeter) causes ionization and field emission of the gal

21:17 <Noxz> lium atoms."

21:17 <Noxz> neat neat

21:18 <nmz787> yeah it's a field-emission source

21:19 <nmz787> basically a small coil/spring looking wire that is wetted with gallium, then a current is passed through the coil/spring to heat up the metal and help it flow/melt a bit... then there's another potential between the coil and the sample stage which extracts ions downward through the optics

21:20 <nmz787> apparently the only thing you really need to worry about is isotopic purity, because multiple atomic-weights will cause focus blurring (ghosting I've heard)

21:22 <Noxz> very neat though, I didnt know the physics behind it.. as I was interested moreso into electron beam w/ PMMA

21:27 <nmz787> apparently the exposure mechanism is the same with either beamsource

21:28 <nmz787> just breaking the polymers into smaller ones

21:29 <nmz787> I've said this before, but if anyone has moved since, if you're in/around the Portland OR area, and have a decent amount of free time, I would enjoy coming to tool and get my (personal) SEM and FIB up and running

21:29 <nmz787> I also have a spin-coater too, the same one I used at the part-time job where I did this recent work

21:30 <nmz787> I only lack proper fume hood/ventilation

21:30 <Noxz> I'm in Seattle..

21:30 <nmz787> ah, yeah I seem to recall that

21:30 <Noxz> I havent setup my fumehood (for chem stuff) since moving

21:30 <Noxz> but I am here for ~2 more years

21:30 <Noxz> I basically was offered a job back home in Ohio upon graduating

21:30 <nmz787> I was spin-coating some ebay photoresist a year or two ago and had to stop because I was getting high

21:30 <Noxz> have a meeting w/ the VP of Brand on tuesday regarding that

21:30 <Noxz> lol

21:31 <nmz787> nice

21:31 <nmz787> I am from western PA

21:31 <Noxz> chlorobenzene is the solvent used w/ PMMA

21:31 <nmz787> can't imagine moving back there after getting addicted to being out here with all the hiking and ecosystems

21:31 <Noxz> do you know of Lititz, PA? that's where the other big watchmaking school is

21:31 <nmz787> Noxz: the PMMA I used was dissolved in anisole

21:31 <Noxz> hrrmm

21:31 <nmz787> http://microchem.com/pmma_faq.htm

21:32 <nmz787> "Our PMMA A resists are formulated in anisole, while our PMMA C resists are formulated in chlorobenzene. We introduced the PMMA A resists in response to the environmental concerns expressed by many of our customers with PMMA resists formulated in chlorobenzene solvent."

21:32 <Noxz> ahh

21:32 <Noxz> very interesting

21:32 <nmz787> iopscience.iop.org/article/10.1088/0957-4484/27/3/035302/ampdf

21:32 <nmz787> using 80-proof ethanol to develop

21:32 <nmz787> versus this crazy 5 or 6 chem recipe with multiple toxics

21:33 <Noxz> hey, if it isnt dangerous, I dont want to do it :P

21:33 <nmz787> I get enough of that driving around here

21:33 <nmz787> lol

21:34 <Noxz> working on getting my [bio]diesel engine going.. still bicycking to school

21:34 <Noxz> just picked up decent rain gear

21:34 <Noxz> right now the engine is my #1 personal project, beyond watchmaking stuffs

21:34 <nmz787> the old recipe the company had on hand featured things like MIBK and ethoxyethanol, and a few others

21:34 <nmz787> nice

21:35 <nmz787> I've got a Jetta TDI that I've tooled on a bit

21:35 <Noxz> ethoxyethanol isnt crazy.. I think that is what is in the Purple Power cleaner

21:35 <Noxz> hrm, maybe not that one..

21:35 <Noxz> Simple Green is similar enough

21:36 <Noxz> C9-11 Alcohols Ethoxylated

21:37 <Noxz> so your personal SEM/FIB arent running just yet?

21:40 <nmz787> nah, the SEM needs some electronics debugging, and the FIB was sold in working and calibrated condition 1.5 years ago but I never uncrated it after getting it home

21:40 <nmz787> been changing the dehumidifier religiously

21:41 <nmz787> since it's in the garage

21:42 <Noxz> hrrrmmm.... https://www.govdeals.com/index.cfm?fa=Main.Item&itemid=179&acctid=3732

21:42 <Noxz> $50

21:42 <Noxz> so far

21:43 <nmz787> hmm, I was just mentioning a MALDI-TOF recently

21:44 <nmz787> to someone else

21:44 <nmz787> CO is pretty far though for a whim

21:44 <Noxz> yeah, it does say some parts appear missing, but they have no idea

21:45 <Noxz> iunno though, looks like a sweet find thus far

21:45 <Noxz> registering for that website sucks ass though

21:45 <Noxz> you have to call into someone to send you a registration link because they got fake accoutn spamed so bad

21:46 <Noxz> 8ftx4ft.. space for it might be -meh-

21:46 <Noxz> 3ft*

21:58 <nmz787> probably includes real estate for vac pumps and gas cylinders

21:59 <Noxz> yeah, vac pumps are in there from what I can tell

21:59 <Noxz> all in one unit

22:00 <pie_> by the way do you guys know theres a "vacuum hackers" discord

22:01 <pie_> i dont really like discord but not everyone uses irc and theres some good stuff there

22:01 <Noxz> .. no... link please

22:01 <Noxz> I am on like 3 discord servers

22:01 <Noxz> there's a a chemistry one that is starting to pickup some pace

22:01 <Noxz> irc is kinda dead for what ti is.. kiddos dont wanna use it

22:01 <pie_> i think this is it https://twitter.com/nanographs/status/1064707554012348416

22:02 <pie_> Noxz, eh, im kind of a kiddo :P

22:02 <pie_> though tbf discord dint exist when i started ircing

22:02 <Noxz> yeah, well, you go to where the content is or you get lost, right?

22:04 <pie_> eh.

22:04 <pie_> i guess

22:05 <Noxz> not get lost, but miss out unless it is linked elsewhere

22:05 <Noxz> but, if you dont know your are missing out (or rather, you dont know what you are missing out on) then meh

22:13 <Noxz> sync is on there :P

22:19 <pie_> yea

22:20 <pie_> smh :P

22:48 <nmz787> is there an IRC-discord bridge bot?

22:48 <nmz787> I like IRC too compared to the web-based stuff

22:48 <nmz787> mostly just because I want things centralized

22:49 <nmz787> is discord a website?

22:49 <nmz787> oh, maybe I'm thinking slack

22:50 <nmz787> either way, I wish there were some bridges

22:54 <Noxz> bots sorta exist, one server I am on uses one

22:54 <john_cephalopoda> nmz787: Hmm, you could make a single site, describing your specific process, or make a site with a basic description and sub-sites describing the general idea and basics of the used techniques. Both work.

22:54 <Noxz> bridge bot, that is

22:54 <john_cephalopoda> nmz787: What's your github handle?

22:54 <Noxz> nmz787, I use discord as a website, I dont use it on my phone at all

22:54 <Noxz> but I know they have apps

22:54 <nmz787> john_cephalopoda: nmz787

22:54 <Noxz> I dont use irc on my phone [anymore] netiher

22:55 <nmz787> yeah I used to use an IRC phone client, but usually I just SSH to a server that's always on so I can have backlogs and such

22:56 <nmz787> and on the phone that is just annoying

22:59 <john_cephalopoda> nmz787: Ok, invite sent.

22:59 <john_cephalopoda> Noxz: Have you got access to the homecmos wiki yet?

23:03 <Noxz> I have ventured onto there I think, but I havent done anything to warrant adding info

23:22 <pie_> nmz787, i made one at some point but it was actually just a thng hacked into my friends hobby project so theres probably better things

23:22 <pie_> also bitlbee is a thing but im not sure how good it is

23:23 <pie_> im a bibliography fanatic, just start aggregating books and papers you like lol

23:23 <pie_> (in a somewhat organized manner :P
