B0101: can you join the googlecode project? Sure, PM me your googlecode email
<B0101>
Ok... Gimme a second
<azonenberg>
wolfspraul: hmm... this means my email shows up in logs *wonders if there's a way to spamproof this*
<wolfspraul>
sorry got disconnected
<wolfspraul>
azonenberg: those logs are updated every 30 minutes
<azonenberg>
ah
<azonenberg>
Can you clear them? CIA dumped an email address i'd rather not get too spammed into the channel
<azonenberg>
working on a new filter that'll spam-sanitize emails
<wolfspraul>
no need to do more instantaneous, I think. From my experience so far, the most important is a good search feature, and that works.
<wolfspraul>
sure, will do
<wolfspraul>
as for the logs themselves, I can totally give you server access and you can do with them whatever you like
<wolfspraul>
so later we can always cleanup, move all to one domain, or whatever you want
<wolfspraul>
I'm not an information hoarder :-)
<azonenberg>
Lol
<azonenberg>
Yeah, as of now i just want the info to be out there where people can find it
<wolfspraul>
just email me your public key (wolfgang@sharism.cc)
<azonenberg>
SSH or GPG?
<wolfspraul>
ssh
<wolfspraul>
so I think 'search' is what most people use
<wolfspraul>
it works quite well
<azonenberg>
Yeah, agreed
<azonenberg>
wolfspraul: For now i can't see any easy way of doing search-and-replace on usernames, and since googlecode insists on using emails as usernames i'll just not include the author in the CIA message
<azonenberg>
just the files and log message
<berndj>
"pyrex" isn't pyrex anymore; "pyrex" is just a trademark, and modern cookware labelled "pyrex" is no longer borosilicate, but just tempered soda-lime glass
<azonenberg>
berndj: Interesting
<azonenberg>
I knew pyrex was a trademark but i just assumed it was all borosilicate
<azonenberg>
Most of my actual labware is Borosil brand
<azonenberg>
And i know for a fact that's borosilicate still :P
<CIA-67>
[removed] * r78 /wiki/FreeEDATools.wiki: Created wiki page through web user interface.
<azonenberg>
I thought i fixed that, hmm
<berndj>
labware would typically be borosilicate, i imagine
<azonenberg>
Let's try this again...
<berndj>
amateur telescope makers greatly regret the decreasing availability of borosilicate
<CIA-67>
79 wiki/FreeEDATools.wiki Dummy commit to test new CIA bot configuration
<wolfspraul>
azonenberg: I'll clean it later if you don't mind
<wolfspraul>
during the day the log file is open, so I have to restart the bot (don't know better)
<azonenberg>
No rush, i just dont want to leave it up there for a long time to get spidered
<wolfspraul>
I'll go through tomorrow and remove the address...
<azonenberg>
Ok, thx

B0101: You're now a contributor (can file tickets on the bug tracker, comment on tickets, and comment on wiki pages) plus EditWiki permissions
<azonenberg>
if i see good work you may get full commit access in the future
<azonenberg>
Anybody else?
<azonenberg>
B0101: The FreeEDATools wiki page is just a start, if you're looking for something to work on feel free to add some more content there
<B0101>
ok
<azonenberg>
As with all of the other wiki pages, of course, but that's one that i specifically know needs work
<azonenberg>
Going to grab a bite, then off to the lab for some testing of liftoff patterning using a slightly thicker hardmask than yesterday
<berndj>
i just checked, magic's native file format looks pretty merge-friendly
<azonenberg>
berndj: Interesting, I might have to take a look at that
<berndj>
its UI does however look like something that escaped from 1980
<azonenberg>
I'm not really tied down to Glade very much, i only have a few test patterns and i can always dump them into a GDS and pull them into another tool
<berndj>
but i found i got used to it fairly quickly
<azonenberg>
Want me to set you up on the googlecode project too? You can add such info to the wiki
<berndj>
i don't think i'll be much of a contributor, but do as you like ;)
<azonenberg>
well if you're interested pm me your googlecode email

Oh, CIA logs any changes to the wiki...
<azonenberg_lab>
Time to have some fun...
<azonenberg_lab>
B0101: There seems to be a little formatting glitch on the EDA tools page - i think you need a blank line after the heading marker for it to format right
<azonenberg_lab>
Other than that, good start
<B0101>
ok noted
<azonenberg_lab>
W00t
<azonenberg_lab>
This one looks pretty good
<azonenberg_lab>
Gonna try baking it and KOH'ing
<azonenberg_lab>
Some residue in areas that should have been lifted off but the hardmask looks undamaged where it should be
<bart416>
Looks achievable enough if you have access to a lathe
<lekernel>
is that a diffusion pump?
<bart416>
Yes
<azonenberg>
I do, my school machine shop has several manuals and one CNC
<berndj>
azonenberg, that H-shape fringe thing i'm looking at, is the fringey bit the Ta2Cl layer?
<azonenberg>
berndj: The background is silicon
<azonenberg>
The fringes are Ta2Cl10
<berndj>
ah.  those edges make it real difficult to count :(
<lekernel>
azonenberg: cryopumps are super simple, they're just a bottle of zeoliths frozen with liquid nitrogen
<azonenberg>
the active ingredient in Tantalumfilm (solvent is denatured alcohol which has already evaporated)
<azonenberg>
Which hydrolyzes to Ta2O5 after baking
<azonenberg>
lekernel: I know
<azonenberg>
It just means keeping cryogenics around
<azonenberg>
one more thing to add to the supplies list
<azonenberg>
A diffusion pump might be doable though
<bart416>
Liquid nitrogen doesn't come cheap...
<lekernel>
there is an article explaining how to DIY them in Amateur Scientist
<lekernel>
liquid nitrogen is 10 cents a liter unless you get ripped off
<bart416>
You get it at 10 cents a liter?
<bart416>
Wow o_O
<berndj>
yup
<bart416>
Where the hell do you buy it?
<berndj>
big industrial users of oxygen have tanks of liquid oxygen
<berndj>
at the gas yard :)
<bart416>
Only place where I can get it here is a small lab about 5km down the road
<berndj>
if you have an interesting story (and you do) you could twist someone's arm to let you "find" some while they aren't looking
<azonenberg>
lol
<berndj>
you don't really care about purity though; just the low temp
<bart416>
lol
<azonenberg>
True, since i'm not exposing it to the chamber directly
<azonenberg>
Just through conduction
<berndj>
don't lol, that's how a model rocketry guy i know got his oxidizer!
<azonenberg>
o_O
<bart416>
berndj, mind you these are the same guys that were willing to sell me nitroglycerine...
<berndj>
now you made me lol
<bart416>
Not much but still o_O
<bart416>
You know where you might find some info on building a good vacuum pump
<bart416>
All those fusor project websites
<bart416>
You need a pretty good vacuum pump for that
<azonenberg>
Yeah, good point
<berndj>
hmm, i vaguely recall there being a yahoo group specifically for vacuum stuff
<azonenberg>
I was going to save that until I had lithography working, but if anyone wants to do the research and post info to the wiki that'd be great
<azonenberg>
Evaporation is a lot easier to do than sputtering and also has better liftoff profiles
<azonenberg>
And i'd prefer it, but i need a way of getting deep vacuum
<berndj>
if you want to / have to avoid vacuum (for now), could that silvering process + electroplating help?
<azonenberg>
berndj: No, i have other deposition needs that cant be done without vacuum
<azonenberg>
For example, polysilicon
<berndj>
ah, ok
<azonenberg>
I have five silicon crystals suitable for evaporation (5mm cubes) sitting around waiting for a suitable chamber, pump, etc lo
<bart416>
wtf, somebody is building a linac in his garage o_O
<berndj>
i thought for polysilicon you run some silane (SiH4) CVD type process?
<berndj>
yup bart416
<azonenberg>
berndj: CVD is the most common method
<azonenberg>
But you can evaporate or sputter too
<bart416>
That sure as hell beats the fusor guys
<azonenberg>
Its just less popular for mass production
<bart416>
But you aren't doing mass production...
<azonenberg>
Exactly
<azonenberg>
Hence sputtering or evaporation are preferred
<azonenberg>
i want to avoid keeping SiH4 around at all cost :p
<azonenberg>
A small amount of argon for sputtering, if i cant avoid it, ok
<bart416>
Yeah, but argon isn't that expensive all things considered
<bart416>
Unless if you want enough for the rest of your life
<azonenberg>
I'm more concerned about the safety implications of keeping giant cylinders of potentially toxic gases in the living room :P
<azonenberg>
A small 20 ft^3 lecture bottle of argon i can handle
<bart416>
Argon isn't toxic :P
<azonenberg>
but SiH4 is both flammable and toxic and i dont want it around
<bart416>
heh
<azonenberg>
Argon is inert and pretty harmless
<bart416>
Maybe you can use helium, that'd be even cheaper
<azonenberg>
Especially if the cylinder is small enough that hypoxia from a leak isnt a serious concern
<azonenberg>
bart416: for sputtering you need a reasonably heavy gas
<azonenberg>
neon or argon work best
<berndj>
something's wrong in http://en.wikipedia.org/wiki/Silicon - check boiling point vs vapour pressure table.  boiling point listed as 2628K, but 100kPa vapour pressure at 3537K???
<B0101>
Bye guys, off to work!
<bart416>
berndj, go and get a good periodic table, don't use wikipedia!
<berndj>
i think even a big cylinder of argon won't displace enough of the air in your room to cause a problem
<berndj>
maybe the tiniest of bathrooms
<bart416>
the only way I see it cause a problem if it releases its entire contents at once
<azonenberg>
berndj: 20 ft^3 isnt a concern
<azonenberg>
I just would be cautious about one of the several-hundred-ft^3 ones
<bart416>
But then it's probably going to create some extra ventilation holes to compensate for that
<azonenberg>
Leaks of those (especially N2) have been known to make a decent sized room hypoxic
<azonenberg>
the trouble with inert gases is that you dont realize you're out of air until you keel over
<azonenberg>
vs CO2 you notice immediately
<berndj>
bart416: door-sized ventilation holes?
<bart416>
berndj, I'd say that depends on the material the wall's made from :')
<azonenberg>
But in a nice large room (20-30 feet across) 20 ft^3 would be harmless even if released all at once
<bart416>
In a nice large room worst case scenario you'd get a little bit light headed
<berndj>
20ft room would be maybe 3200ft^3... displacing even several hundred ft^3 shouldn't kill you
<bart416>
Damnit stop working in non SI units, it's confusing o_O
<berndj>
air is 20% O2, you'd need to halve that to kill.  funny, was just reading about fire suppression
<bart416>
<3 Halon :P
<bart416>
It's a shame they banned it
<bart416>
Best fire extinguishers ever :S
<bart416>
Those regular ones in cars are crap
<bart416>
You can't even put out a small camp fire with those
