<Noxz>
the cords for it eventualy got hot, but yeah, intersting initial test
<Noxz>
the first idea was for crackign ethanol to ethylene
<Noxz>
w/ Aluminum Oxide granuals - then powder
<Noxz>
never really realized well enough though
<Noxz>
anywho, I got some "Test tubes" that were ~ 300mm in length
<Noxz>
the glass blower I reached out to made smoking stuff, but had exp w/ borosilicate.. so yeah.. he had to order all of the ground glass joints and I had to wait
<Noxz>
so long as it worked, and it did
<pie__>
cool
<pie__>
man i need to start doing not nothing :D
<Noxz>
do you at least have a wishlist of what you wanna do?
<Noxz>
I actually have an idea of making an aluminum oxide coated mesh for use with steamed vapors to crack/dehydrate
<Noxz>
which stemed from a magnesium oxide electron multiplier design
<pie__>
well i want to start with one of those DIY SEMs (its either a sem or a TEM or something like that, i keep mixing it up)
<Noxz>
yeah, SEM is my first aim
<pie__>
im not really set up for any sort of chemistry and im not sure i can set up for it :/
<Noxz>
I'm going about it way differently than Ben though
<Noxz>
I mean, if you ever seen one of Ben Krasnow's chem setups - it's usually a simple distillation or similar
<Noxz>
he doesnt exactly have a fumehood
<Noxz>
I, however, do
<pie__>
diy sem probably isnt really useful for anything but it seems at least a doable thing for starters
<Noxz>
I want to use it for e-bram lithography for electroforming small watch parts
<pie__>
i keep saying SEM because they are both S*M :|
<Noxz>
you linked me to that before - very neat
<Noxz>
I like the idea of using piezo
<pie__>
i think they use piezo normally, its just a LOT fancier
<Noxz>
especially since I have piezo stages and ultrasonic homogenizers
<pie__>
right now im just trying to focus enough on studying to not fail the semester horribly
<pie__>
i might have ADHD, but its gonna be a while till the doc appointment
<pie__>
(or im just trash at studying :P)
<Noxz>
team meeting - daily standup, bbiab
<pie__>
a'ight
<Noxz>
heh, depends on subject for me
<gruetzkopf>
i've built a fairly terrible STM before
<pie__>
what do you do anyway?
<Noxz>
IT
<Noxz>
as a general term
<Noxz>
site triage I think is a more proper thing of the new group
<pie__>
gruetzkopf, oh?
<gruetzkopf>
for uni
<Noxz>
oh, meeting canclled, bossman is in training
<Noxz>
k, time to slack and chat :P
<pie__>
haha
<Noxz>
gruetzkopf, I'd like to know more about your end product as well
<Noxz>
yay, email back: bench test one week out, next tuesday!
<sync>
nowadays I feel like it is more productive to just buy a surplus sem/tem
<Noxz>
you mean second hand on fleabay?
<Noxz>
and pray it works
<pie__>
everything that involves things like making your own silicon out of sand are probably going to be less productive... which i ams sadly starting to internalize :P
<pie__>
thats just a made up example
<pie__>
wafers are relatively cheap
<sync>
there is not much to be broken, if the e gun works
<pie__>
what part of a sem is even the hard part? optics? metrology instruments?
<pie__>
(basically everything important)
<sync>
it depends, the hard parts are the electron optics and the controls for them
<sync>
if you want it to work well
<Noxz>
Ben's implementation didnt seem too bad
<Noxz>
not too hard
<sync>
yeah but also no real use
<sync>
tbh, I want to use the em not make it
<Noxz>
did it not work? he got a professionally made second hand one later
<sync>
and even using a commercial one is a lot of fiddling
<sync>
yes, the second one is good
<pie__>
i wonder how hard it is to simulate electron optics
<pie__>
open source electron microscope design anyone? (pff who needs to be able to manufacture things anyway)
<pie__>
i love how any competent person would just make a business out of any of these ideas if they actually did them
<pie__>
i mean, this is all srs bzns, so you might as well
<Noxz>
can a living room fabricated SEM compete against a commercial one?
<Noxz>
competition, cost, reproducability, etc
<Noxz>
time
<pie__>
i meant the design side
<Noxz>
but is there a market for that?
<Noxz>
who will gain what from it
<pie__>
for living room designed sem? probably not, but if you're trying to seriously design a sem (in your living room) i guess you might as well go into engineering proper
<Noxz>
ea component is likely fairly custom to any real degree that publishing any info of it is very specific to what was chosen
* pie__
doesnt really know anything about anything, just frustrated about opportunities probably
<Noxz>
jack of all trades?
<pie__>
i guess
<sync>
there is electron optic simulation software
<sync>
even making the parts is not hard
<sync>
the devil is in the details tho
<pie__>
Noxz, well, that would be if i actually learned the stuff properly enough :P at the moment, just pining to be a jack of all trades :P
<pie__>
sync, yeah i figured as much
<Noxz>
such as the cooling of the magnets for consistent precise results
<pie__>
sync, the basic theory is not hard, but you arent gettng an undistorted image at 1um
<Noxz>
it's nearly just a CRT
<pie__>
yeah when i found out about the original method of syncing (heh) the beam scanning to crt scanning i thought that was pretty neat
<Noxz>
.. what is the method?
<Noxz>
I dont recall much of it
<Noxz>
and syncing = ?
<Noxz>
it is slightly early for me
<pie__>
something something what they originally did was modulate the microscope beam scanning and the crt beam scanning with the same signal (well, scaled appropriately)
<pie__>
at least, thats what i was told
<Noxz>
to reuse some of the electronics?
<sync>
no, so that you can see the image
<Noxz>
oh
<sync>
actually not uncommon way back when
* pie__
goes back to linear algebra
<pie__>
sync, does microscope software usually give you an api to script stuff?
<sync>
no?
<pie__>
thats dumb :P
<pie__>
then again, i guess it will usually have stuff for scanning a large area at high res anyway
<sync>
well, yes
<sync>
but almost nobody would write a script anyway
<pie__>
annoying to draw dicks on an ungrounded sample by hand
<gruetzkopf>
let me see if still have the stuff from that lab
<gruetzkopf>
i still have the boards, but sadly not the X/Y/Z piezo stage
<Noxz>
$200 book that took a month to get to me from middle of nowhere kentucky.. I should have paid the $5 extra (if available) for expediated shipping
<Noxz>
it has some underlinings in the first chapter, but beyond that, decent condition
<pie__>
sounds like you need to scan it and put it on the internet
<pie__>
unless you got it because you just wanted a physical copy
<Noxz>
it was not on libgen
<Noxz>
I had to buy a physical one
<pie__>
yeah, hint hint wink wink nudge nudge
<pie__>
Our Benevolent Library
<Noxz>
I like how scihub will link to there if you put in something that is actually a book (even if it has a DOI)
<Noxz>
I also like the slight UI change scihub did, moving the stuff to the left
