<azonenberg> This is the same process I use with FT256 package
<azonenberg> havent tried on FG484 but i expect it to work
<kristianpaul> Thanks !
<kristianpaul> Do you concern about transition times when changing owen temperature?
<kristianpaul> seems dont :)
<kristianpaul> gotcha, visual inspection is fundamental
<azonenberg> kristianpaul: yeah, its all human-in-the-loop feedback
<azonenberg> not scalable to mass production but requires very little fancy equipment
<azonenberg> i do have the capabilities to make a real profile controller
<azonenberg> building one is on the short-term TODO list
<azonenberg> its going to be ethernet enabled
<azonenberg> so i can put a board in there
<azonenberg> then go back to my desk and dial in a profile
<azonenberg> and it'll beep when its done
<kristianpaul> is more like an OpenCV PID
<kristianpaul> if you think about infrared..
<azonenberg> Lol well the real one is going to be based on a thermocouple and a relay
<azonenberg> and some kind of closed-loop feedback loop

<Jia> lekernel: may you tell me how did you use clang&binutils? I mean, how could you make clang calling as&ld?
<kristianpaul> Jia, i tried once from here https://raw.github.com/milkymist/milkymist-ng/master/README
<kristianpaul> if you mean for lm32...
<Jia> yeah, lm32, and, your help is awesome

<Jia> kristianpaul: cmake ..; make; make install is there anything like --prefix= ?
<kristianpaul> should be, but dont find it in the CMakeLists.txt
<kristianpaul> last time i installed clang was using with autotools :)
<kristianpaul> lekernel: fake dma? :-)

<lekernel> Jia: I modified clang
<lekernel> see the last commits in git
<lekernel> I don't know about your build error ... works for me... are you using clang/llvm from the milkymist github?

<lekernel> Jia: there are others. this one is just to match the cpu name from binutils.
<lekernel> kristianpaul: no
<lekernel> what's Amber?
<kristianpaul> check opencores
<larsc> amba?
<kristianpaul> free of arm patents they claim so far it called my antetion
<kristianpaul> afaik no mmu

<azonenberg> kristianpaul: open source ARM core?
<azonenberg> i'm sticking to mips since its a nice old architecture
<azonenberg> all patents on mips1 have long since expired
<kristianpaul> azonenberg: kinda yes, old arch same as your mips core
<azonenberg> Well yeah, all the current ones are patented up the wazoo
<wpwrak> kristianpaul: 40 MHz on a Spartan 6 45T ...
<wpwrak> kristianpaul: (page 45 of the PDF) 80 MHz on a virtex
<azonenberg> wpwrak: 40 MHz on an ARM core on s6?
<azonenberg> even my MIPS hits 80, do they have significantly better performance per clock?
<azonenberg> half the clock rate would need a much more efficient architecture to be competitive
<kristianpaul> wpwrak: need to verify that without the ddr3 controller from xilinx
<lekernel> azonenberg: can you deposit titanium films (on a KTN crystal)?
<azonenberg> In house, or do i hav access to it?
<azonenberg> In house the only film coating i can do is spin coating, i plan to build a sputtering setup but don't have the parts yet
<azonenberg> i can however do evaporation on campus
<wpwrak> azonenberg: they only compare it with itself. so no idea how it compares with other cores in real life. 1.0 MIPS/MHz suggests they're not ~2x faster than the rest of the pack (which they'd need to make up for the low clock speed)
<lekernel> :)
<lekernel> including titanium?
<azonenberg> Let me look up the temps
<azonenberg> I've done copper (melts 1084C boils 2562C)
<azonenberg> titanium is a little higher (1668 and 3287)
<azonenberg> i've also done Cr (1907, 2671)
<azonenberg> and while i have not personally other people use the tool for gold (1064, 2856)
<lekernel> I'm trying to build a laser scanner/projector out of this https://www.ntt-review.jp/archive/ntttechnical.php?contents=ntr200709sp2.html
<azonenberg> So it should be possible to get hot enough
<lekernel> after reading up, it's a little more complicated than what I thought
<lekernel> first those KTN crystals are expensive as hell
<azonenberg> The tool cannot get hot enough to do Pt (1768, 3285)
<azonenberg> 3825*
<azonenberg> vapor pressure is too low
<azonenberg> and hmm...
<lekernel> then, I read mentions of the crystal lattice orientation, but they are contradictory. so I should actually find a way to make failures less expensive. I know a crystal processing workshop in Berlin, maybe I'll order a boule and process it locally
<azonenberg> lol nice
<azonenberg> wpwrak: 1.0 MIPS/MHz is comparable to my architecture
<azonenberg> maybe eve na little worse if they're talking DMIPS
<azonenberg> and i clock twice as fast
<azonenberg> no experience with LM32 but i'v eheard its comparable to a hair faster than mine
<lekernel> and finally, the electrodes. seems you need more than just an electric field - you need an ohmic junction to inject some electrons into the crystal. and the way to do that is to deposit titanium on a polished face.
<azonenberg> I see
<azonenberg> well, sputtering it shouldnt be too difficult
<lekernel> so, except those three "little" problems, it seems like a cool technology :-)
<azonenberg> i havent built a sputtering system yet, its the third on my TODO list
<azonenberg> the first two being a better spin coater and a 2-inch contact mask aligner
<mumptai> a DIY foundry?
<azonenberg> mumptai: #homecmos
<azonenberg> its coming along slow since i'm doing it part time while in school
<azonenberg> but it is moving
<lekernel> azonenberg: so, titanium sputtering sounds like something you would be capable of doing?
<azonenberg> Am currently capable of, no. Will be at some point, yes
<mumptai> cool
<azonenberg> how long it'll take depends on a lot of factors
<lekernel> well, using tools on the campus. get it done, no matter how ;-)
<azonenberg> If i can evaporate it, i can do it easily
<lekernel> induction heating should be possible, no?
<azonenberg> evaporation is done with a tungsten filament
<lekernel> ah, I see... old school
<azonenberg> the hard part is getting the necessary vacuum
<azonenberg> 1E-6 torr range
<lekernel> does it really need to be that perfect?
<azonenberg> Yes
<azonenberg> Sputtering can be done much hgiher
<lekernel> or else?
<azonenberg> 1E-3 to 1E-2
<azonenberg> You get oxidation etc
<azonenberg> sputtering is done with an inert gas plasma at low temperature
<wpwrak> azonenberg: (MIPS) yes, DMIPS. so it sounds like a nice achievement in terms of proof of concept. but it doesn't quite feel as if they had just obsoleted what we have.
