<azonenberg> GenTooMan: no, debugging a complicated mixed signal circuit ;p
<azonenberg> :p *
<azonenberg> But also, just trying to do toolchain improvements
<azonenberg> i want one app that can capture data from all of my instruments (FPGA LA, both DSOs, etc)
<azonenberg> right now i have a modular back end so i can use one or the other in any given app instance
<azonenberg> but i cant link them into one larger virtual instrument
<azonenberg> lolol
<azonenberg> the point is to avoid that
<azonenberg> one app and a bunch of cables going off into the nether
<awygle> it's 2017, they should all be wireless :)
<qu1j0t3> plzno

<cr1901_modern> Everything should be point-to-point. With ARP proxies on each node.

<azonenberg> awygle: If somebody makes a wireless link that can run at 10+ Gbps without FEC latency overhead
<azonenberg> with multiple lanes coexisting in a close area
<azonenberg> i might *consider* switching :p
<awygle> azonenberg: there's 7 whole GHz open in the 60gig band now! i mean, you'd lose data anytime you walked between the scope and the router, but...
<awygle> does your lecroy have 10G out? seriously doubt the router does
<awygle> ... s/router/rigol/, what is wrong with my fingers today
<azonenberg> My lecroy does not
<azonenberg> but my starshipraider will
<azonenberg> the lecroy is an older model, doesnt even have gigabit :p
<azonenberg> and i dont care about internet access
<azonenberg> i want point to point 10gbit from the PC to the starshipraider and a few other places

<cyrozap> I ordered a bunch of hard-to-find ICs from Taobao--anyone want to decap them to see if they're fakes? I got some R820T2 TV tuners, LG3306A (a.k.a. LGDT3306A) ATSC/ClearQAM demodulators, and some Toshiba HDMI/DP to MIPI DSI bridges.
<cyrozap> Interesting thing to note about the TV demods: Modern TV demodulators are pretty much all DSP-based, so I'd be interested to see if the LG chips have their code in mask ROM or flash and what kind of core they use.
<cyrozap> Also, yes, I'm half-trying to build an open source TV tuner device. Well, actually two--one that uses the LG chip, and the other that's basically just an SDR capable of receiving a full 6-8 MHz TV channel so the demodulating can be done in software.

<awygle> azonenberg: "TRAGICLASER"?
<azonenberg> That's the project codename
<awygle> i understood STARSHIPRAIDER immediately (although maybe not why it had to be all caps) but why TRAGICLASER
<azonenberg> I suck at naming things so... https://twitter.com/NSANameGen
<awygle> ahhh
<azonenberg> starshipraider is one of the few that actually has a story behind it
<awygle> that's actually not a terrible plan
<awygle> but now you have to rename xbpar to CLINICALLINKAGE
<azonenberg> lol
<azonenberg> no, i only do this when i cant think of good names
<azonenberg> Hmm
<azonenberg> so my 100M driver might need just a little work
<azonenberg> But let's see
<azonenberg> funny enough its the "0" state thats tricky
<azonenberg> not the +1 and -1
<azonenberg> Alhtouhg some of that may be inductance of my big long pmod wires and breadboarded PTH resistors...

<awygle> Given the total lack of impedance control and all the extra inductance
<awygle> Where's the HDL?
<azonenberg> Lol
<azonenberg> Sec, let me pastebin it
<azonenberg> its in a vivado project in /tmp lol
<awygle> What are you doing for the pcb, oshpark 4 layer?
<azonenberg> Yeah
<azonenberg> Based on this PoC i think i'm good to go, will do a final layout review then send to fab tomorrow
<awygle> Well looking forward to seeing the result in a couple weeks
<azonenberg> I haven't tested the RX but the comparator trick is pretty standard
<azonenberg> worst case i tweak resistor values
<awygle> I guess I should learn kicad someday...
<cr1901_modern> (That being said, I'd rather use Kicad than anything else nowadays)
<azonenberg> yeah its pretty nice
<azonenberg> and i'm not even using the latest build
<azonenberg> once i get this board taped out i'm gonna update to latest
<azonenberg> i'm using 2017-07-19 actually which isnt that old
<cr1901_modern> But, I've DEFINITELY had my share of library issues and problems that cascade into each other (hence the linked tweet)
<azonenberg> I just dont use the libraries
<azonenberg> :p
<azonenberg> I use my own libs and i hand verify them all
<azonenberg> the only stock parts i use are the schematic symbols for "generic connector" and passives
<cr1901_modern> I know... that IPC spec is a PITA to read
<cr1901_modern> Chris Pavlina has a bunch of FreeCAD libs that are IPC compliant (which I was using before you uploaded your libs)
<rqou> so as azonenberg probably predicted, i am bad at ppe and spilled some methanol on myself
<rqou> fortunately, i live with a bunch of alcoholics :P
* azonenberg throws gloves and a lab coat at rqou
<azonenberg> Consider yourself lucky it wasn't WFNA
<azonenberg> or HF
<rqou> i was using gloves
<rqou> no lab coat though
<rqou> I'll be much more careful with HF/WFNA
<azonenberg> Yeah, go get one
<rqou> having the experiment not on the floor would also probably help :P

<azonenberg> oh, and go get a fume hood
<azonenberg> srsly, you're at a university
<azonenberg> cant be hard to find one you can pretty-please access to
<rqou> cleaning optics in a fume hood probably isn't the most efficient use of the fume hood

<sn00n> i mean, i knew that the dice would be much smaller than the VQ100 package, but that's quite a difference
<sn00n> and since it's my first time i used cheap IC like a small ice40 and a esp32
<sn00n> if i had a bonder i could rebond them and look if they still working
<sn00n> the lack of a bonding apaaratus makes me feel incomplete :<

<rqou> woot, i got super lucky
<rqou> a photomicro adapter l _just_ showed up on ebay
<rqou> for quite a bit less than the guy who is custom-making dovetail to t-mount adapters
<sn00n> cool
<sn00n> (what ever that means)
<rqou> it's a very precise hollow tube :P
<sn00n> but super lucky is cool though
<sn00n> ok?
<sn00n> precision!
<sn00n> :)
<rqou> it's used to attach dslr cameras to olympus trinocular heads
<sn00n> ah ok
<rqou> (well, it was originally designed for a film camera, but nobody has those anymore :P )
<sn00n> guess i made such a thing on a lathe
<rqou> the flange focal distance of film cameras tends to be huge, so we're lucky again
<sn00n> if you mean those olympus trinocular heads for the BHM series?
<rqou> this tube works for the BH, BHM, and BH-2
<rqou> and maybe some others?
<sn00n> ok, than i understand
<rqou> the olympus unofficial compatibility chart is ridiculously huge
<sn00n> i made a ring dove 2 T-2 adapter tube
<rqou> ah, nice
<rqou> there's a guy who sells those for people who aren't super good with a lathe
<sn00n> and on the t-2 i can use those cheap commercial T-2 to bayonette adapters
<sn00n> i'm not supergood with a lathe, thread cutting is kinda semiautomatic
<rqou> hmm from what you're saying i assume you also have a BHM?
<sn00n> ok, with a CNC it would be 100% automatic :)
<sn00n> yes
<sn00n> an old olympus
<sn00n> but i'm a n00b
<rqou> do you happen to know how to fix "stage is too loose?"
<rqou> i used to have "stage barely moved" so i tore it down and rebuit it
<rqou> now i have "stage is too loose"
<sn00n> shot it on ebay 2 months ago
<sn00n> hmm
<sn00n> mine is not to lose! i guess
<sn00n> you mean to loose as in it moves if you are breathing?
<sn00n> your question is if you need the right grease or something like that?
<sn00n> i dunno
<sn00n> maybe
<sn00n> or do you mean back lash?
<sn00n> i didn't reworked the stage yet, so i dunno
<rqou> too loose as in "it moves if you are breathing"
<rqou> no appreciable backlash
<sn00n> so stop breathing?
<sn00n> hmm, ok, that's impractical
<rqou> it's hard to have backlash when there's _one_ pair of gears mating :P
<sn00n> ah
<sn00n> well ... :)
<rqou> we have a different stage, don't we? :P
<sn00n> is it a worm gear?
<rqou> it's a rack and pinion
<sn00n> as i said, didn't disassembled it yet
<sn00n> ah ok
<rqou> i had to disassemble mine because it didn't move at all before
<sn00n> ok, mine was fine
<sn00n> so i IPAd it a bit & done with cleansing :>
<rqou> olympus seems to have quite a few problems with this grease making things stuck
<azonenberg> sn00n: you decapped a hx1k?
<azonenberg> i have one already decapped and imaged, but forgot to upload :p
<azonenberg> and a 4k but the 4k image got corrupted due to a glitch in the stage controller
<azonenberg> it's missing a couple of frames
<sn00n> azonenberg: yep, currently
<rqou> e.g. i had an illuminator where the "Pull BF" rod couldn't move at all
<sn00n> azonenberg: but my intention was not to be the first or something
<rqou> and it was stuck halfway in between BF and DF
<rqou> so that needed a complete rebuild too
<sn00n> azonenberg: only wanted to try "decapping"
<azonenberg> sn00n: well at some point i want to get a full multilevel SEM image
<sn00n> azonenberg: multilevel SEM means?
<rqou> currently doing a rebuild of the trinocular head, which is also stuck
<sn00n> complere dice down to i dunno 2nm resolution?
<rqou> which is how i ended up spilling methanol on myself and decided i was done for the day
<sn00n> (i know ice40 is like 40nm process?)
<sn00n> rqou: y methanol?
<rqou> websites i've seen recommend a mix of acetone+methanol
<sn00n> rqou: ethanol is the stuff you want in your body, methanol simply makes you blind
<sn00n> ok
<sn00n> ah
<sn00n> not IPA?
<sn00n> hmm
<rqou> apparently IPA evaporates too slowly
<sn00n> those japanese!
<sn00n> japanese clean evereything with acetone it seems
<rqou> anyways, today i'm going to work sitting at a desk rather than sitting cross-legged on the floor :P
<rqou> this will have a much lower probability of unintended spills onto the crotch :P
<sn00n> hehe
<azonenberg> sn00n: you dont need full resolution everywhere
<azonenberg> only for poly and implant
<sn00n> yepp
<azonenberg> even at m1 feature sizes are larger so you can shoot at lower mag
<azonenberg> But yeah i want full netlist recovery for fun
<sn00n> hehe, ah, that would be cool
<sn00n> but currently i'm just playing around with "preparation" techniques to get a feeling for it
<sn00n> a nice toolchain from from "imagery" over BReP stuff like GDSII/OASIS to netlist in $yourfavouritenetlistformat would be killer indeed
<sn00n> does such a toolchain exist? :)
<rqou> you should work on it :P
<rqou> a lot of people would like something like that
<sn00n> me? or he?
<sn00n> we?
<rqou> we i guess
<sn00n> all of us? yeah
<sn00n> hehe
<rqou> the current procedure involves an army of monkeys, eyestrain, and inkscape :P
<sn00n> ew, inkscape
<sn00n> it's cool for t-shirts & flyers :)
<sn00n> stickers!
<rqou> yup, most current netlist recover takes a round-trip through inkscape first
<rqou> unless it's ROM-only
<sn00n> spraying stencils!
<rqou> sn00n are you based in the US?
<sn00n> nope, i'm from germany
<rqou> hmm ok
<rqou> going to 34c3?
<rqou> i'll be there
<sn00n> dunno (didn't have a ticket yet :>)
<sn00n> hadn't enough money
<sn00n> but maybe the voucher works in a few weeks, than i'll buy one
<rqou> you should poke whoever has the ##openfpga voucher
<sn00n> or are there deadlines? ^^
<rqou> felix_, eduardo__ ?
<sn00n> i have access to a voucher pool, but i'vent the money now
<rqou> oh :(
<rqou> i can't really help with that
<sn00n> but in a few weeks
<sn00n> no prob
<sn00n> it's kinda strange ... the presale is early this year, right?
<sn00n> can't remember 33c3 >_<
<sn00n> vouchers floating around since 6 weeks or something
<sn00n> 8 weeks?
