<azonenberg>
I dont usually do heavy industry type stuff, personally...
<azonenberg>
I prefer extreme precision at tiny scales
<bart416>
Should have asked my father to bring a tank (he's an officer in the army :P )
<azonenberg>
lol
<bart416>
Leopard tank vs Wall would have been funny
<bart416>
Sad reality is that the wall had a high chance of winning
<azonenberg>
Well, the problem is that use of the main gun wouldnt be feasible given proximity to civilians and your house
<bart416>
The thing with these tools is, they're actually fairly precise
<azonenberg>
I'll bet that 120mm APFSDS will go through that concrete no problem lol
<bart416>
Uhm, the wall was 40 cm thick...
<bart416>
Reinforced tensioned concrete...
<bart416>
With a sand layer
<azonenberg>
40cm? Shoudlnt be that bad *looks up penetration stats*
<bart416>
20cm of that would have been steel though...
<bart416>
And my father wants to break down a shed the guy built (also in concrete) :|
<azonenberg>
Quick googling suggests that current russian APFSDS rounds have penetration equivalent to 65cm of rolled homogeneous steel armor
<bart416>
I'm going to go and ask for a crane + wrecking ball
<azonenberg>
I dont know how much easier/harder concrete is, but my guess is you'd get most of the way through if not all the way
<bart416>
Probably
<bart416>
But doubt there'd be much damage after the wall considering how thick it is
<azonenberg>
Yeah, you'd be punching a hole through
<bart416>
but keep in mind this wasn't even a support wall of the house...
<azonenberg>
APFSDS does most of its damage from pyrophoricity on the inside
<azonenberg>
Non-explosive
<bart416>
I wonder what the support walls look like
<bart416>
Should borrow an ultrasound from college lab for a day :P
<azonenberg>
lol
<azonenberg>
ground penetrating radar?
<bart416>
dunno, don't have access to that
<bart416>
+ an ultrasound I actually know how to use :P
<bart416>
ground penetrating radar I do not
<azonenberg>
lol
<bart416>
Too bad you can't just take a piece of a wall out and use a MRI scanner, those are horribly easy to control o_O
<bart416>
Really it's a joke with the new software
<bart416>
A 5 year old could do it
<azonenberg>
lol
<azonenberg>
I dont think mri would work well on concrete anyway
<azonenberg>
And i'm not too familiar with any penetrating imaging methods
<bart416>
I'm more worried about the steel inside of it :P
<azonenberg>
I mostly do optical and some electron microscopy
<azonenberg>
Ah, forgot it had rebar
<azonenberg>
And the guy who trained me on the SEM in our cleanroom says that he's taught 14-year-olds how to use similar models lol
<bart416>
If a small none support wall already has rebar...
<bart416>
most of these devices aren't really hard
<bart416>
Anybody can work with a MRI, just don't bring anything magnetic close to it and you'll be fine
<azonenberg>
lol
<bart416>
Well, a modern one at least
<bart416>
body part, patient position on table (depending on how the table is arranged really), algorithm (you can sometimes choose), single frames, 3D, record over time, ...
<bart416>
All nice options in the menus, lol
<bart416>
And afterwards it'll ask where to send it if it hasn't been pre configured
<berndj>
bart416, you into amateur telescopes or why're you pasting the ingalls link?
<azonenberg>
nice
<bart416>
Even contains the nice option to burn one of those annoying CDs with those crappy viewers
<azonenberg>
berndj: They have a part on sputtering
<bart416>
Well, they mention some articles about it
<bart416>
+ also about other methods of coating
<bart416>
And vacuum systems in general
<bart416>
And I sort of am actually
<bart416>
But I bought my telescope
<bart416>
But the mirror has its best time :(
<bart416>
You into amateur telescopes berndj ?
<azonenberg>
has done a decent amount of astro stuff but never built his own scope
<bart416>
I'm probably going to sell mine
<bart416>
Too much light polution anyway
<bart416>
When I move to a desolated part of Vietnam in about 30-40 years I'll pick it up again
<berndj>
yes, i am into amateur telescopes
<berndj>
just haven't worked on mine for a few months
<bart416>
The cost is prohibitive sadly
<berndj>
i don't recall any mention of sputtering, but then again book 3 is the one i don't have
<bart416>
Want me to upload it again?
<berndj>
what i did see was evaporation
<bart416>
That's also covered
<berndj>
nah, it's okay
<berndj>
you might've had better luck with a thermal lance vs that wall
<azonenberg>
I was actually gonna suggest that lol
<bart416>
berndj, next time I'm cutting to the rebar and I'm pulling out a plasma cutter
<bart416>
Lets see how it likes that >_>
<berndj>
oh, azonenberg, what was that about cutting tungsten wire?  for what purpose?
<bart416>
he wants to make probes
<berndj>
that desktop STM project i may have mentioned (some dude at uni the year before me built one) had probes made from incandescent bulb filaments just pulled apart
<azonenberg>
berndj: I have two six-foot pieces of 400 micron tungsten wire from amazon
<azonenberg>
only a few dollars each
<bart416>
Heh, STM is on my to do list
<berndj>
turns out you don't need great precision in forming the tip - almost any chunk of tungsten will have *some* part of it that forms an adequate tip
<bart416>
STMs are fairly easy
<azonenberg>
I plan to use the STM technique (electrochemical etching) to sharpen them
<azonenberg>
Building a STM and later a SEM is on my todo list too
<azonenberg>
But i need more workbench space
<berndj>
oh, for probing a chip?
<azonenberg>
my lab is growing :P
<azonenberg>
berndj: Yes
<bart416>
What you really need is a good electron microscope so you can see the current flow in future prototypes :P
<azonenberg>
I have a wentworth labs probing station that i got used on ebay and am in the process of fixing up (needs some vacuum hoses replaced and a good cleaning but is otherwise in decnet shape)
<berndj>
but not an actual STM?
<azonenberg>
And an actual STM would be nice too
<azonenberg>
But is a bit further out
<bart416>
The best part is that you can just take apart a buzzer to get the piezo electrode
<bart416>
But don't have a scope so it's hard to build this sort of thing anyway
<bart416>
Bah
<bart416>
So instead it's going to be the more insane project
<bart416>
Try to put an ARM Cortex A8 on a double sided board
<azonenberg>
Lol
<azonenberg>
Have fun
<azonenberg>
is equally insane but wants to do 4 layers on a xilinx BGA fpga
<bart416>
Heh
<bart416>
Dunno
<bart416>
How much pins is it
<bart416>
Mine is 400 or 500 or something like that
<bart416>
Also where do you get 4 layers?
<azonenberg>
bart416: ExpressPCB is what i've been using but i'm leaving
<azonenberg>
Probably 4pcb 6 layer is what i'll end up using
<bart416>
o_O
<bart416>
That costs close to $200...
<bart416>
My total budget for my entire project is less than that
<azonenberg>
I'm not paying for it :P
<azonenberg>
My advisor will be
<bart416>
If you can get a good powerplane + ground plane it's a lot easier
<azonenberg>
I need >1 power plane lol
<azonenberg>
at least a 2.5 and an 1.2v, maybe a 3.3 as well
<azonenberg>
plus ground
<azonenberg>
then two to three signal layers
<azonenberg>
it will end up being a six or eight layer board i think
<azonenberg>
XC6SLX75 is the plan
<azonenberg>
plus some sdram, flash, and other fun stuff
<azonenberg>
and maybe an MCU for stuff i dont want to waste fpga gates on
<bart416>
It's the same league
<bart416>
Difference is, I'll have to do it at home with a toaster oven >_>
<azonenberg>
will be having the board fabbed professionally but hopes to assemble it in a toaster oven here
<azonenberg>
256-FTBGA package lol
<bart416>
oh that's easy :|
<azonenberg>
Its 1mm pitch
<azonenberg>
Shouldnt be nearly as bad as the 0.8 i was thinking of doing earlier
