<azonenberg> Hung 30 feet of cable tray today, then ran out of mounting hardware
<azonenberg> (somehow i didnt buy enough)
<sorear> what am I looking at
<sorear> ah
<sorear> something about these photos gives me a strong feeling of "photos are upside down"
<azonenberg> sorear: No, this is right side up
<azonenberg> in the second photo you're looking at a garage door
<azonenberg> in the background
<azonenberg> open roof and walls with no insulation or sheetrock
<azonenberg> With $wife poking her face around through a hole in the wall
<azonenberg> Sorry for potato, i didnt bring my good camera to the house today b/c derp :p
<Zorix> hehe that last picture reminds me of an old polaroid
<azonenberg> Lol no its my phone
<azonenberg> Second cheapest android the t-mobile store had two years ago, lol
<azonenberg> (cheapest was a tiny piece of junk)
<azonenberg> Surprisingly it still gets security patches

<gruetzkopf> those us fuseboxes always look wrong to me
<gruetzkopf> then again the design is logical if you only have a single- or splitphase supply
<azonenberg> gruetzkopf: that particular panel is a recalled design
<azonenberg> UL revoked their listing 20+ years ago because the breakers don't trip reliably
<azonenberg> I knew that as soon as i bought the house and actually bargained the price down bbbbbbbbbbecause of it
<azonenberg> because*
<azonenberg> I have no experience working on service equipment so i'm having a pro replace it
<azonenberg> je
<azonenberg> he's coming a week from tomorrow
<azonenberg> But i'm replacing all of the wiring past the panel
<azonenberg> in any case the house's service is 200A split-phase
<azonenberg> No 3-phase here (for now)
sunxi_fan has joined ##openfpga
<rqou> O_o you upgraded to a 200A service?
<azonenberg> AFAIK it always was a 200A
<azonenberg> i'll confirm when the electrician redoes the panel
<azonenberg> but thats what i was told in the past
<azonenberg> We're just doing a 1:1 swap of the panel with a new, non-recalled one
FabM has joined ##openfpga
<azonenberg> (and the new one is bigger)
<azonenberg> as in more breakers, not new bus bars
<azonenberg> or bigger service entrance wire

<gruetzkopf> https://i.ebayimg.com/images/g/HHQAAOSwBahU7tHm/s-l600.jpg this is common in germany. GFCI and circuit breakers are put on din rail, an then connected with threephase busbar
<gruetzkopf> one might have 1-n such rows in a panel
<azonenberg> yeah everything i've seen here is split phase

<rqou> slight offtopic: what is the best way for a "technical but not CS" type person to stay connected to IRC?
<rqou> including on Android
<awygle> I use quassel. You need a host someplace but you can deligate that to someone who sysadmins
<balrog> I use znc but it's something of a pain for initial setup
<rqou> i personally use znc, but with tls client cert auth
<rqou> so no "normal" people can use it

<rqou> so as part of a class i get to play with a piece of software called plecs
<rqou> i don't usually praise proprietary software, but this one is really really cool
<rqou> it does integrated circuits, magnetics, thermal, and feedback controls simulation
<rqou> it's a (newer design??) state-space simulator rather than whatever SPICE does
<rqou> it comes out of ETHZ, so it fits with the "fancy school" way of thinking about things :P
<awygle> i remember learning state-space techniques for feedback controls
<awygle> and being pissed that they'd wasted all that time teaching me root-locus plots when state space made so much more sense
<azonenberg> Speaking of simulation
<azonenberg> lain: pokey pokey
<azonenberg> we need a f/oss 3d field solver
<azonenberg> :p
<lain> ikr
<rqou> lol the no-PhD field solver?
<rqou> :P
<rqou> oh ninja'd
<lain> I've been reading about photonics
<rqou> btw azonenberg have you seen openEMS?
<rqou> (other than "this is way too complicated")
<azonenberg> pretty much, yeah :p
<azonenberg> couldnt figure out how to do anything useful with it
<azonenberg> What i want is the ability to generate continuous 3D geometry from gerber + stackup data (or maybe a kicad layout or something)
<azonenberg> Click on a point in the geometry and drive a signal onto it, sourced by a given IBIS model
<azonenberg> model passives and other stuff
<azonenberg> and look at the simulated field on another wire
<azonenberg> etc
<rqou> btw i thought pcbs normally only need 2d field solvers?
<rqou> there is a tutorial to get openEMS to import a gerber, but i don't think i ever got it to work
<rqou> it also requires octave for some reason
<azonenberg> try doing fun stuff like modeling ground plane cutouts under SMA connectors
<azonenberg> to get matched impedance
<azonenberg> you need a 3D solver for that
<rqou> (plecs also uses octave though)
<rqou> why does this industry like octave so much?
soylentyellow has joined ##openfpga
<rqou> azonenberg, lain: you should make your field solver use tcl just to make people upset :P :P
<azonenberg> eew eew eeew
<lain> tcl is overdone
<lain> if you really want people to hate it, use haskell
<rqou> lol
<rqou> how about clojure?
<rqou> functional _and_ JVM
<rqou> :P
<azonenberg> Y U no malbolge?
<rqou> Clojure, VHDL, and spreadsheets, all combined! :P
<cr1901_modern> tcl isnt... that bad?
<azonenberg> no, it's worse
<azonenberg> :p
<cr1901_modern> I mean I wouldn't use it over Python for scripting, but I can live with it...
<qu1j0t3> rqou | functional _and_ JVM // there's also Eta, now (Haskell on jvm). And of course Scala is 15 years old
<rqou> but Scala seems to actually be designed to be usable
<rqou> e.g. it's not a lisp-like
<rqou> apparently plecs has an xml-rpc interface and can be scripted from Python in addition to octave
<rqou> why don't more programs have that?
<qu1j0t3> rqou: also, vs clojure, scala is statically typed
<rqou> I'm increasingly of the opinion that most software should be designed as a libfoo and have a ffi-friendly or rpc interface
<rqou> and guis should be built on top
<azonenberg> I prefer C++ API in the library then gui on top
<rqou> I'd never do it that way. Makes it incredibly difficult to connect to Rust/Python/etc.
<azonenberg> So you're saying i should make my library more awkward in order to support integration with languages i don't use?
<rqou> somewhat :P
<rqou> it's pretty unfortunate how primitive the "least common denominator" ffi interfaces are
<rqou> another choice is to use json-rpc or whatever instead of a ffi interface
<rqou> e.g. what we can easily turn yosys into :P
<azonenberg> also
<azonenberg> that is impressive
<awygle> rqou: hear hear
<awygle> also I love these new high frequency power supply ICs
<awygle> If your inductor doesn't fit in a
<awygle> resistor footprint don't even talk to me
<azonenberg> awygle: lol
<azonenberg> So some of the fun new SMPSes are meant to be used with PCB trace inductors
<azonenberg> other fun ones have integrated inductors in the molded package
<lain> yeah
<lain> TI has some.. I think they're called nanoswitch or something? they have inductors soldered on top, chipscale controller /inside/ the pcb
<awygle> I have used the latter. Also ones where the inductor is pre-assembled on top of the module
<lain> it's a tiny pcb in bga package iirc
<sorear> no inductor, just using parasitics?
<awygle> Sign me up for pcb trace inductors though that sounds great
<awygle> The synthesizer on my mixer board does that but at like 1GHz
<awygle> And power and RF continue to converge...
<azonenberg> lain: i used those in a design a while ago
<azonenberg> i think the starshipraider prototype has that
<azonenberg> the bga package pcb module i mean
<azonenberg> but it has a discrete inductor on top
