reportingsjr: next will be animated MEMS version of nyan cat ;-D
<reportingsjr>
kristianpaul: :P
<reportingsjr>
that's hilarious
<azonenberg>
reportingsjr: nyanotechnology
<reportingsjr>
what size?
<reportingsjr>
hahahahahaha
<kristianpaul>
azonenberg: btw this last pic very clean
<azonenberg>
Probably a ~2mm overall
<azonenberg>
with 20um comb drives to move the feet
<reportingsjr>
haha
<azonenberg>
and different thicknesses of SiO2 for the rainbow
<azonenberg>
kristianpaul: ty
<azonenberg>
This is 200nm evaporated copper over Si patterend by wet etch in dilute HCl : H2O2
<azonenberg>
Still having adhesion problems
<azonenberg>
going to try putting 5nm or so of Cr under the Cu next run
<azonenberg>
probably next week
<kristianpaul>
you have a  micromanipulator right? wih one if?
<azonenberg>
micromanipulator brand probing station (forget exact model) with a B&L stereozoom microscope (plus some additional upgrades for eyepieces etc to boost magnification)
<azonenberg>
and three micropositioners
<azonenberg>
two of one type and one of the other
<azonenberg>
110 and 210 are left and right handed
<azonenberg>
i forget which is which
<azonenberg>
they're otherwise identical
<azonenberg>
and good down to ~5um targets (bottom-of-the-line units i got cheap)
<azonenberg>
5um is still good enough to hit anything my process can make though :)
<reportingsjr>
azonenberg: how long until you get a working comb drive ya think?
<azonenberg>
reportingsjr: Hoping for soon
<azonenberg>
1-2 motnhs i hope to have 2.5D (separate top and bottom etches meeting in the middle of the wafer) patterning working
<azonenberg>
then i have to figure out how to insulate the metal from shorting against the body
<azonenberg>
and adjust the geometry to get something that works
<azonenberg>
end of year is a relatively realistic estimate
<azonenberg>
optimistically, oct-nov
<bart416>
lol, this guy is worried about settings on a dental xray :|
<bart416>
azonenberg, ever had the joy of seeing the control system of a full body xray scanner?
<azonenberg>
lol i would imagine its long
<azonenberg>
and complex
<azonenberg>
at least if the controls for a SEM are any hint
<bart416>
the easy settings are acceleration and exposure time
<azonenberg>
My point is, a slight malfunction is far more likely to result in you getting cancer in 10 years
<bart416>
You can't even approach the dose of a CT scanner on a regular xray machine
<bart416>
+ there is also a hardware safety
<bart416>
a hard limiting circuit you can't bypass without pretty much disassembling the entire machine
<bart416>
at least in most there is
<XgF>
suspects that the branch of physics he's interested in is more likely to have an effect on his health :p
<bart416>
XgF, please tell me you're not into nuclear physics?
<XgF>
...and even then a trivial effect
<XgF>
Bingo :p
<bart416>
I had to quit that...
<XgF>
Around the time I get my degree, ITER will be coming online... which would probably be good timing for any postgrad research
<bart416>
ITER would be fairly safe...
<XgF>
Indeed
<bart416>
Where do you live XgF ?
<XgF>
UK
<bart416>
Might be hard to get into ITER considering how much frenchies are about :(
<bart416>
Medical imaging is safer...
<bart416>
You can sit in your nice leaded glass cage
<XgF>
Medical imaging involves Biology... I hate biology
<bart416>
It's fun
<bart416>
At least, the technical part is
<XgF>
Generally, I find that as you strart with Maths and move upwards through the sciences, I end up liking them less and less as they become less derivable
<bart416>
I'll agree on that if you're talking about MRIs
<XgF>
But hell... I have no clue where I'll be in 3 years. For all I know I could decide to take advantage of the skills I've gained from my side job and become a freelance lighting engineer...
