<wpwrak> xiangfu: how are you sending the cables ? air mail ?
<xiangfu> DHL
<xiangfu> air mail, DHL.
<wpwrak> DHL is courier or regular mail in this case ? regular mail is better if there are problems, because customs clearance is in the city, not a trip out to the airport
<wpwrak> we now have a restriction on "internet purchases", with a very fuzzy definition of what that is supposed to mean, so please make sure it doesn't look like a "purchase"
<wpwrak> (the good news are that there will be new elections in october, when the idiot government we have to thank for for all this insanity will hopefully receive a kick in the butt ...)
<wpwrak> gerbers look good. there are a few slightly sloppy spots but hopefully the pcb makers won't mind. specifically, issues that may not like:
<wpwrak> 1) there's sometimes silk screen on solder mask openings. clearances should still be well sufficient to avoid trouble. if they really hate it, tick "Subtract soldermask from silk screen" in the Gerber dialog.
<wpwrak> 2) one positioning mark of the OLED FPC touches a hole (for the switch). this is expected and there's nothing we can do about it. the PCB makers should just try their best there. if the positioning mark doesn't make it or comes out wrong, that's not a problem.
<wpwrak> 3) the battery pads exceed the PCB. again, that's intentional. they'll have to trim them in one way or another. the edge outline is right, so the pads should be cut.
<wpwrak> 4) similarly, there is silk screen for the switch and for the memory card holder that exceeds the board outline. again, the excessive silk screen should just be ignored.
<wpwrak> most likely, the only thing they may complain about is 3). you may want to attach a note telling them that we know this and that they should just cut off as much of the pad as they have to.
<wpwrak> and you don't need to send them anelok-Dwgs_User.gbr or any anelok-*_Paste.*, but they probably already know to ignore such things :)

<DocScrutinizer05> HP err Agilent err KeySight
<DocScrutinizer05> never before seen or heard of such a monster
<DocScrutinizer05> I wonder oif they actually had a test spec that says "device - except fuse - survives 10 times applying 600V AC at ESR 1mOhm to the Ampere range probe jacks"
archang has quit [Ping timeout: 265 seconds]
<whitequark> 600kA?
<whitequark> oh, 30kA fuse
<DocScrutinizer05> yeah, capable of breaking 20kA
<DocScrutinizer05> err 30
<DocScrutinizer05> nominal blow is 11A
<DocScrutinizer05> hihi, lightning thunder the very moment I sent "err 30"
<DocScrutinizer05> more than 600V though ;-P
<DocScrutinizer05> 30kA sounds about right for lightning as well
<wpwrak> current may be about right, though: http://hypertextbook.com/facts/1997/BrookeHaramija.shtml
<DocScrutinizer05> :-D
<DocScrutinizer05> eventually I'll have to check how much ionizing radiation lightning emits. There are claims lightning even causes fusion reactions (H -> He)
<DocScrutinizer05> X-ray sounds absolutely plausible. gamma claimed to be observed, though sounds not plausible. Alpha, well... dunno
<whitequark> well
<whitequark> a fusor is a pretty simple device
<DocScrutinizer05> sure
<whitequark> you need 4keV to fuse D-T
<DocScrutinizer05> extremely simple but *huge*
<DocScrutinizer05> I prefer thinking in degrees Kelvin
<DocScrutinizer05> simpler than transforming temperature into "speed"
<DocScrutinizer05> I guess in lightning the problem isn't the temperature but the pressure
<whitequark> too high? hmm
<DocScrutinizer05> the H+ won't get accelerated sufficiently to collide, by the electric field
<DocScrutinizer05> only change is to accelerate them by high temperature and high pressure
<whitequark> not sure about "high pressure", in a fusor you have dilute gas
<whitequark> i mean the issue here is mean free path
<whitequark> if it's too low, you aren't accelerating the ions fast enough
<DocScrutinizer05> yeah, when you accelerate ions in a filed, it is
<whitequark> at 1atm it is on the order in 400nm
<DocScrutinizer05> field*
pcercuei_ has quit [Ping timeout: 276 seconds]
<DocScrutinizer05> laser fusors work by shooting laser beams on a tiny ball of fusion material from all sides, to create a sort of containment, by both light pressure and explosion momentum. While same time heating up the material to extreme temperatures
<whitequark> yeah, but a lightning is nowhere near that
<DocScrutinizer05> of course you can fusion H+ in even tiny cyclotrons, in vacuum, but that's not how lightning works
<DocScrutinizer05> so much for my uneducated take on "lightning creates fusion reactions"
<DocScrutinizer05> I doubt it
rejon has joined #qi-hardware
<whitequark> >quora
<DocScrutinizer05> >> yield of ~1015 neutrons per lightning flash<< LOL

dandon has joined #qi-hardware
<DocScrutinizer05> dang, the (not included!!!) 134 pages manual for the U1233A obviously has zilch info about the supported command set, only a vague pointer to that dang windoze app "Agilent GUI Data Logger Software"
<DocScrutinizer05> hmm http://www.keysight.com/upload/cmc_upload/All/release-note1.txt >>4. Removed Scpi command SYST:TENV 1<< Seems I'm up to my own to test SCPI commands if they work with U1233A or not
<wpwrak> maybe look for the 34401A command set. should be very similar
<DocScrutinizer05> any pointer for that one?
<DocScrutinizer05> agilent website sucks big time
<wpwrak> the keyword you need is "scpi" :) http://cp.literature.agilent.com/litweb/pdf/34401-90004.pdf

<DocScrutinizer05> however
<DocScrutinizer05> sense:voltage:dc:range?
<DocScrutinizer05> *E
<DocScrutinizer05> *E is the standard response to virtually everything
<DocScrutinizer05> actually *IDN? is the only command so far that produces anything other than *E
<DocScrutinizer05> and switching the rotary dial produces *1 *2 *3 aso depending on position
<whitequark> ugggggh scpi
<wpwrak> some devices let you send "button presses" and return a bitmap of which LCD segments are active in response ;-)
<wpwrak> so be thankful for SCPI :)
<DocScrutinizer05> pressing the pressing the "TRIG HOLD / AUTO LOG" blue button produces "unsolicited response code" like "010016512000200" (incl ") for a display reading of 16.5 mV AC
<DocScrutinizer05> only one though, for each keypress
<larsc> if only devices would follow the standard
<wpwrak> now where would be the fun if they did ?
<DocScrutinizer05> yeah :-/
<larsc> what I've heard is tha often devices speak a dialect that is only compatible to the vendors control software
<wpwrak> ... and whatever you have to write to talk to the critter regardless :)

<wpwrak> the MEAS command should override the manual setting
<DocScrutinizer05> how would it do that on a turndial button?
<DocScrutinizer05> even when it does - I doubt MEAS for the mode currently manually selected is invalid

<wpwrak> oh :)
<DocScrutinizer05> whitequark: don't tell me, tell KeySight!
<wpwrak> but wait ... you're beginning the command with a * ? that doesn't look right

<DocScrutinizer05> with and without *, with sub and subsub-cmd

<DocScrutinizer05> <CR> doesn't work
<DocScrutinizer05> needs ^J or ;
<DocScrutinizer05> funny enough it accepts ; just like ^J
<DocScrutinizer05> I think 0.000V is good enough of a stable voltage
<wpwrak> ah yes, there's something wrong with the command. checking ...

<wpwrak> at least mine doesn't like it
<DocScrutinizer05> it takes ; as termination for almost everything, even READ?, since it instantly answers with *E
<DocScrutinizer05> according to SCPI specs ; is for multiple commands per line. So I thought "duh, lazy sucker simple did ';==^J' to simplify stuff"
