<azonenberg>
and my current tool of choice, a halogen microscope illuminator
<azonenberg>
The resist that I use (shipley SP24) is most sensitive to 405nm
<azonenberg>
which is what blu-ray diodes emit
<azonenberg>
Its also included in the output from halogen and mercury vapor lamps
<azonenberg>
s/halogen/incandescent/
<azonenberg>
The resist is sensitive from i think around 365 to 450ish nm
<azonenberg>
so a wide-band source will work (at the expense of energy wastage and chromatic aberration, which slightly blurs the image but usually not enough to be problematic at these feature sizes)
<B0101>
hmm... I was thinking of making my own "photolithography box"
<B0101>
where I place the wafer inside a box which contains 6 halogen bulbs
<azonenberg>
Halogens heat up a lot though
<azonenberg>
if you have a sealed box go with UV fluorescent
<azonenberg>
and the problem is that you cant align easily in such a setup
<B0101>
hmm... yellow light conditions for photoresist...
<B0101>
lol, i was about to ask what is red light until i thought about LED's
<B0101>
Azonenberg: hows your spin coater project?
<azonenberg>
B0101: I use yellow bug lamps for illumination during litho
<azonenberg>
And you mean the more accurately controlled one?
<azonenberg>
Low priority, the one i have is good enough for now
<B0101>
ok
<azonenberg>
Heading off to bed in a bit - its after 1 AM here lol
<B0101>
I am also heading off to my lab to do experiments, cya later
<bart416>
Mhhh, computer with corrupted bios
<bart416>
It still sort of boots
<bart416>
But after the first I/O input from keyboard it hangs up
<bart416>
or first attempt to move mouse
<bart416>
- I/O
<bart416>
anyway, attempt to flash the rom without booting the computer or not? :P
<B0101>
Azonenberg: Hi, I've found the PDF file of the book "Introduction to Microfabrication"
<B0101>
you want it?
<bart416>
B0101, why wouldn't we want it xD? :P
<B0101>
bart416: Your IRC client can receive files?
<bart416>
Nope :(
<B0101>
whats your email?
<bart416>
Had to disable DCC all together cause I got attacked too much >_>
<bart416>
sorry, have a policy of not handing my email out on irc anymore either >_>
<B0101>
ok then
<bart416>
dxz29JNZw9fIwznN@x.trillianpro.com
<bart416>
I always wondered if spambox supported forwarding of attachments :P
<B0101>
we'll see
<B0101>
sending it over
<B0101>
darn it
<bart416>
I guess not lol
<bart416>
oh well, was worth a try
<bart416>
I'll come online anyway later with a client that supports DCC
<B0101>
wait
<bart416>
At university it doesn't matter if I get DDoSed with DCC requests
<bart416>
I can draw a full 100 mbps anyway there
<bart416>
worked
<bart416>
Thanks!
<B0101>
i don't know if the file can be read, I had to cancel it off as i got the still working message for a long time
<B0101>
test opening it first
<B0101>
well? does it open?
<bart416>
Sorry, was putting a dish in the oven
<B0101>
never mind
<bart416>
works like a charm
<B0101>
how many pages are there in in total? (verification check)
<B0101>
there should be 422 pages altogether
<B0101>
Sorry if it troubles you
<bart416>
Yeah 422
<bart416>
The thing about PDFs is, if they're damaged they often don't open at all
<bart416>
Or all the data is lost
<bart416>
It's a really fucked up format in that way
<bart416>
I've found the best description of the format's redundancy to be zero nilch
<B0101>
I agree
<B0101>
wth? so fast?
<bart416>
?
<B0101>
nothing really, just that 1 of my servers went down (CPU fail)
<B0101>
total uptime 3 months only
<bart416>
Hardware failure or segfault?
<B0101>
hardware failure
<bart416>
What's broken?
<bart416>
(I mean what cpu)
<B0101>
AMD Phenom 2 X6
<bart416>
mhhh, what socket is that one?
<B0101>
give me a second...
<B0101>
socket AM3
<bart416>
Argh :(
<bart416>
sorry, don't have CPUs for that socket
<B0101>
well, not an intel fan but their Xeon processor is more stable, my AMD server would crash at least twice every week
<bart416>
Refurbished single core xeons are brilliant, but the cooling and power requirements are nuts
<B0101>
yup, but for me, stability is more important
<bart416>
Well, if your power bill can afford it...
<bart416>
current uptime of my server here is a half year at this point
<B0101>
My intel servers have been up for 9 months since the last maintenance session
<B0101>
oh dang!
<B0101>
i just remembered, the AMD server was hosting FTP
<B0101>
but i don't think i should be running FTP anymore
<bart416>
heh
<bart416>
FTP can be pretty CPU intensive :(
<bart416>
A friend of mine uses routers as FTP and web servers at home
<bart416>
He doesn't want to believe me that getting company/industrial power line drawn into your house and then using that is actually more profitable once you run a few servers :S
<bart416>
Yes, your yearly service costs increase
<bart416>
But price per kWh is so much lower
<B0101>
It will be hell running a FTP server on a P2
<B0101>
i agree about the power thing
<bart416>
lol
<bart416>
The thing about a P2 is that they last forever if you slap a big enough cooler on them
<B0101>
well about the P2, its overclocked to 500MHZ (as i was told by the other admin)
<B0101>
I thought the maximum for a P2 is 450?
<B0101>
btw, I just finished fabricating a JJ qubit, want to see?
<B0101>
its a SQUID actually
<bart416>
Later today :P
<bart416>
It's too warm to think straight
<bart416>
And I've been designing a 16 bit ALU this morning xD
<B0101>
a lot of work eh?
<bart416>
Well, I initially limited myself to only using pencil and paper
<bart416>
But I've decided to use espresso to optimize the ALU
<bart416>
Want a single cycle for every major mathematical expression
<bart416>
addition, multiplication, division, exponents, base 10 and e logarithms, etc...
<B0101>
heh, luckily for you, its a normal ALU
<bart416>
Define non normal? :P
<B0101>
I am trying to design a quantum computer
<B0101>
you cannot do a copy operation on a QC
<bart416>
Yeah, that's a bit trickier :P
<B0101>
why can't you do that? because of the no-cloning theorem
<bart416>
couldn't you just make a function that has one input and two outputs?
<bart416>
And use that to copy?
<bart416>
Feed one output back to the initial qubit and the other to the new one
<bart416>
or do AND 1
<bart416>
Not the most efficient way either
<bart416>
But strictly speaking it's not a copy
<B0101>
you're right, but i will look for better ways
<bart416>
How are you storing the qubit?
<bart416>
or is it a strictly theoretical design and not a physical one?
<B0101>
its a physical one
<B0101>
right now, its stored in a plastic box
<bart416>
You don't know yet or what?
<bart416>
Cause depending on how it's physically stored you might have a few options
<B0101>
so what options can there be?
<bart416>
Well, are you using entangled light?
<B0101>
no
<bart416>
mhhh, fiber optics are out of the question then
<bart416>
can't think of a non destructive way :(
<B0101>
the qubit is solid state (Its fabricated on silicon) and is operated using electricity
<bart416>
ah
<bart416>
sort of skipped every solid state physics class when he was studying physics :(
<B0101>
and thats why its called a SQUID
<B0101>
or Superconducting QUantum Interference Device
<bart416>
Aaaaaaargh, acronyms!
<bart416>
dodges
<bart416>
raises the dictionary as a shield
<B0101>
I will experiment on QD's soon (Quantum Dots)
<B0101>
its some kind of Electron trap
<bart416>
Aren't those sort of big?
<bart416>
as in 0.5 µm scale?
<B0101>
yup
<B0101>
there are also 400+ NM double quantum dots though
<bart416>
Interesting
<B0101>
but what people frequently ask me about Quantum Computing is: "Why am I trying to make one?"
<bart416>
Cause you can? :P
<B0101>
Well, because I with QC's I might be able to crack normal encryption algorithms faster
<B0101>
and, i might improve security with QC's
<bart416>
That's also a good reason
<bart416>
But somehow I doubt the first implementation will be of much assistance in that goal, well not directly
<B0101>
yup
<bart416>
But it'll be a good test bed for future designs
<B0101>
you know whats the current record for a computation made by a QC?
<B0101>
*world
<B0101>
actually, the world record 3 x 5 = 15 on 5 qubits
<B0101>
to many, this will seem like: wth? that simple?
<B0101>
but its hard
<B0101>
decoherence is the problem
<B0101>
if the atoms decohere, the atoms will turn into normal "useless" atoms
<B0101>
those cannot be used for computation
<bart416>
How much bits are you using?
<B0101>
2 bits only
<B0101>
just trying to do a normal 'not' operation
<B0101>
but i think i could just use 1 qubit
<B0101>
They had plans on Diamond Quantum Computers
<bart416>
mhhh
<bart416>
Also B0101 you don't happen to have a fitness store thingy/chain/whatever in real life do you?
<bart416>
A friend of mine who noticed your name in my mailbox just asked lol
<B0101>
nope i don't own a fitness chain/store
<bart416>
Ah, cause when she lived in singapore she used to know somebody with the same name as you that did :P
<B0101>
I'm going off to bed, see you tomorrow
<bart416>
brb, going to do some network maintenance
