SEM photo of 20 micron wires, copper on silicon
<azonenberg>
from an earlier test
<Flea86>
copper on silicon aye? nice!
<Flea86>
:3
<azonenberg>
wet etched, not damascene

<Flea86>
I've also been fascinated at what *could* be done simply by using oxides of copper, however, unity-gain-and-above devices are not one of them.. :/
<azonenberg>
I intend to do doped silicon devices as soon as i have around $2k to spare
<azonenberg>
to buy $250 each P and N type dopant solutions and a $1k furnace for diffusion
<azonenberg>
Just have to do some more research on other stuff first
<azonenberg>
for example, building a nicer spin coater
<Flea86>
:)
<azonenberg>
Which reminds me i should start the CAD on that soon
<superkuh>
What CAD program do you use?
<azonenberg>
Still looking for a good free one
<azonenberg>
for mechanical cad, that is, not mask design
<azonenberg>
the one i've been using so far is an educational copy of autodesk inventor
<Flea86>
azonenberg: What's wrong with inventor, are there any 'limits' imposed on that package?
<azonenberg>
The educational version?
<azonenberg>
The license expires after one year, after which you have to still be a student to renew it
<azonenberg>
and the files are permanently marked "created with educational version" on printouts etc
<azonenberg>
even if opened in the full version
<azonenberg>
also, it doesnt run on linux
<azonenberg>
thats one of the few reasons i keep a winblows VM sitting around
<Flea86>
"<azonenberg> and the files are permanently marked "created with educational version" on printouts etc" Yeah this'd pretty much ruin it for me too :P
<azonenberg>
Its fine for personal projects like i'm doing now
<azonenberg>
but its still a potential problem
<azonenberg>
the bigger problem is not having a native linux release
<azonenberg>
solidworks doesnt either
<azonenberg>
unigraphics does but NX is... a bit buggy
<azonenberg>
last time i checked
<Flea86>
azonenberg: So what kind of mechanical CAD stuff do you need it to do?
<Flea86>
2/3D modelling etc?
<azonenberg>
basic 3d parametric cad
<azonenberg>
and possibly simple simulation but nothing too advanced
<Flea86>
Ah
<azonenberg>
in this case, designing a spin coater
<Flea86>
azonenberg: Perhaps you could try running inventor under wine??
* Flea86
runs
<azonenberg>
Did so
<azonenberg>
i filed a half dozen bug reports
<azonenberg>
and last time i checked not all are fixed
<Flea86>
lol oh..
<Flea86>
:<
<azonenberg>
bug reports, mind you
<azonenberg>
against the setup executable
<azonenberg>
it wouldnt even install
<Flea86>
x.x
<Flea86>
I guess it just shows wine is only good for windows games, if anything..
<azonenberg>
its just that games are what they put the most priority on bugfix wise
<Flea86>
yeah
<azonenberg>
in the longer term i'm thinking of buying a full copy of solidworks and just running it in a vmware system
<azonenberg>
its $4k though
<Flea86>
azonenberg: Apparently one can also lease solidworks as well :)
<Flea86>
(Though I have not yet done so myself)
<azonenberg>
I'd want to buy one version and just stick with it
<Sync>
I use varicad for 2D and 3D cad natively under linux
<azonenberg>
then get a nice linux cnc machining shop set up
<azonenberg>
Sync: tried varicad
<Sync>
it is not great but it works
<azonenberg>
wasnt a fan, its not parametric
<azonenberg>
its like autocad extended to 3d
<Flea86>
azonenberg: In that case, I suggest you look at vectorcam 3D :D
<Sync>
I could care less about it being parametric
<azonenberg>
parametric is the absolute minimum requirement for a 3d tool
<azonenberg>
my workflow requires being able to continually experiment and tweak dimensions etc
<Sync>
I usually use catia now, but it is akward to use in a virtualbox
<azonenberg>
i *want* something like inventor but open source and native linux
<azonenberg>
but nobody seems to be working on such a tool
<azonenberg>
and i dont have the time/skills to make one myself

azonenberg: Yeah, parametric 3d isn't one of vectorcam's strongpoints, although cnc cam is.. }:A
<azonenberg>
CAM is no good without a model to fab though
* Flea86
lags
<Flea86>
azonenberg: Well all I've seen so far suggests solidworks works well enough :)
