<pie___>
anyone here any good with d3js
<sync>
Noxz: no, just a huge reinforced concrete slab in the ground
<sync>
ideally not coupled to the building

<Noxz>
ahh
<Noxz>
my walls are the iffy part, the concrete slab is separated from the walls/foundation by an inch or so of insullation, according to the building plans
<Noxz>
I may have some of these machines that I make on the upper floor though, so the concrete slab means nothing to it
<Noxz>
so, I would still like to look at either DIY or what is available second hand
pie__ has joined #homecmos
<Noxz>
not entirely sure how I would DIY it just yet, but I am going to school at a micromachining lab more or less
<sync>
we put them in the basement for that exact reason
<Noxz>
yeah, well, my "basement" is also my den, dining room, and kitchen
<Noxz>
main access of the house, too
<Noxz>
half underground, the other half not (steep slope, by a bridge, which causes a bit of the vibration due to road traffic)
<sync>
nothing you can't move to the upper floor
<Noxz>
so long as the end device doesnt weigh a ton, then I should be fine upstairs
<Noxz>
but then I need to figure out isolatino
<Noxz>
k, dog walk time
<Noxz>
but glad to be done for the week
<Noxz>
we are in the middle (I am nearly done) with our brass cubes
<Noxz>
10mm, plus a frosted finish

side note: I want a very small force gauge, that can do maybe 100cN max
<Noxz>
0.01g, that is the resolution on my lab scale, but certainly more portable
<Noxz>
maybe simply buying a bare strain gauge and doing a whetestone bridge
<SpeedEvil>
Or an optical sensor and wire of known properties

Is this a suitable hub to discuss inkjet printing of electronics (logic gates, circuits, displays, and input devices)? It's not cmos but it is at home.
<SpeedEvil>
I don't think anyone is really going to object.
<SpeedEvil>
Given the resolutions peole are talking about.
<pointfree>
cool
<pointfree>
I think it's better than starting a new channel and the goals are more or less the same.
<pointfree>
One can get ~50um feature sizes with a cheap Epson or Brother printer.
<SpeedEvil>
e-ink advertisment film is in principle great for low res 'LCD' making.
<SpeedEvil>
All you need is a transparent layer and a PCB.
<john_cephalopoda>
Wow, 90V at high frequency.
<SpeedEvil>
Of course, they won't sell you it

wouldn't know how to scale inkjet manufacturing from his apartment to higher volumes.
<SpeedEvil>
more inkjets!
<pointfree>
I could set up an inkjet printer with a bagel shop conveyor belt toaster for curing in a u-haul storage locker. A secret lights-out turnkey fab.

pointfree, I'm big into graphene, but more pristine than rGO
<Noxz>
graphene at a few layers thick is translucent, and a better conductivity than ITO iirc
<Noxz>
the 'issue' is the control of the number of layers
<Noxz>
and scaling up
<Noxz>
pointfree, the deposition method I am most interested in at the moment is known as Langmuir Films
<Noxz>
I love the idea of inkjet printing it though
<Noxz>
wow, only $250 USD for a simple cutting machine.. havent really looked at them at all
<Noxz>
the resolution of 300dpi on it would equate to under 0.1mm resolution, which could certainly be good enough for experimentation at a certain scale.. our tolerances are currently ~0.03mm on the low end, and we're only at week three, so only going to get smaller and smaller
<pointfree>
Noxz: Interesting. Langmuir films are entirely new to me.
<pointfree>
Graphene is indeed a strong contender to replace ITO. I'm also considering it because it's more flexible than ITO so it could go around the drums of a printer.
<Noxz>
I eventually got a book on langmuir stuff, still working through it
<Noxz>
I didnt know the name for a while, took so long to discover the name of what some scientists were doing in a certain paper
<Noxz>
I am interested in doing a continuous thin film of graphene (pristine) deposited onto a very thin flexible plastic
<Noxz>
the goal is (super)capacitor
<Noxz>
also, I attempted the yellow etch resistant ink in some epsom printer as a direct-write pcb method before.. I left it behind when I moved 5 years ago and havent revisited it.. I was seemingly making okay progress though
<pointfree>
*not sure that I can get a thin enough deposition of graphene/graphite with an inkjet printer.
<Noxz>
you have to come up with the method to do it..
<Noxz>
afaik it doesnt currently exist, but people's layers of graphene are hilariously large all the time
<Noxz>
near pure black/gray
<pointfree>
Noxz: How about the adhesive tape method? The adhesive could go on a drum.
<Noxz>
no way, that is not scalable
<Noxz>
nor do I think it can be continuous
<Noxz>
I am somewhat head-strong about the method I am pushing towards though, so slight bias
