04:55 katsmeow-afk Kansas is tween 0F and 26F, depending on where you are
05:05 tsmeow-afk decides if the game is unwinable, then it is also unloseable, because to lose it you had to have had it, if you cannot have it, then you cannot los

07:52 katsmeow-afk northwest Ks 4F
08:43 katsmeow-afk ok, i gathered temps from different sources, and i think people are making up thetemperatures
08:45 katsmeow-afk currently 77F in Puerto Rico
08:47 katsmeow-afk it's 99 in Nyang Station, Oz
08:50 katsmeow-afk 75F whereabouts Rif is
08:50 katsmeow-afk and it's ~1am there
09:12 tsmeow-afk just had a bot on irc again for the first time in .... a long
09:21 katsmeow-afk A Florida family is in shock after finding its pet horse slaughtered and gutted for her meat.
09:21 katsmeow-afk Rolando Serrano returned to his Hialeah Gardens house Wednesday to discover the animal, named Puti, had apparently been murdered,
09:21 katsmeow-afk "I don�t know, not human, who could do that to animals,"
09:22 katsmeow-afk he then went inside for a cheeseburger and milkshake
09:23 katsmeow-afk the milkshake had eggs in it, and the owner was wearing leather jacket and pants
09:26 katsmeow-afk fake money (and this was accepted as payment by a business) : http://assets.nydailynews.com/polopoly_fs/1.2070030.1420722729!/img/httpImage/image.jpg_gen/derivatives/article_970/fake9n-1-web.jpg
09:30 rue_house how can you be sure its fake?
09:31 rue_house I mean, what if the staples and tape were a correction at the press?
09:31 rue_house :)
09:31 katsmeow-afk they were plain photocopies on ordinary paper
09:32 rue_house what if the press broke down and they made a few of those to not lose ground?
09:32 tsmeow-afk makes a note to run off some $4 and $7 b
09:32 rue_house heh
09:32 rue_house some $5.99 bills for those sales
09:32 tsmeow-afk
09:34 katsmeow-afk "how much is it?" "$29.99 with tax" "hold on...." <taps on cell phone> <drone flies into store with a slightly damp $29.99 bill hanging from it>
09:35 rue_house https://www.youtube.com/watch?v=olHnFWUoJX4
09:35 rue_house crazy russian threads a glass bottle on a lathe
09:35 rue_house love to know what kinda bit that is
09:36 katsmeow-afk threads it? why?
09:36 rue_house russian, how the heck shoudl I know
09:38 katsmeow-afk you know what we should be doing each winter? using electricity ...... to heat synthetic diamond presses, the waste heat would keep the house warm, and the "leftover waste" is a diamond to sell each Spring
09:46 katsmeow-afk cops looking for lug nuts
09:46 katsmeow-afk guy went into high security NYPD parking, stole the lug nuts off 4 cars
09:48 katsmeow-afk A Florida man was arrested for allegedly possessing pot and meth - while wearing a shirt that read: "Who needs drugs? Seriously, I have drugs."
11:11 katsmeow-afk Vandal accused of setting traps for North Vancouver mountain bikers
13:02 katsmeow-afk if someone asks what 2 and 2 is, and you answer 2, why do they think you are stupid?
13:39 katsmeow-afk rue, why does Sia's Chandelier song sound like she is drugged out?
14:28 katsmeow-afk actually, from what i can tell, all her songs sound like she is stoned
14:33 katsmeow-afk i cannot bear listening to any of her songs all the way thru
14:37 tsmeow-afk deletes all of
14:39 katsmeow-afk has USPS crashed? i mean the planes... or routing/tracking computers?
14:46 katsmeow-afk i have a bad feeling usps is handing all it's general mail to DHL, which costs a day handing to at sending end, and a day getting back at recipient end
14:47 katsmeow-afk it's also screwing the up-to-date tracking
15:36 katsmeow-afk "Cable and the rest of the over priced click ."
15:36 tsmeow-afk pulls some hair
15:37 tsmeow-afk screams "clique" at the mon
15:40 katsmeow-afk "and hoist a substandard product on to the world"
15:40 katsmeow-afk AAAAAAAAAARRRRRRRRRRRRRRRRRRRRRGGGGGGGGGGGGGHHHHHHHHHHHH it's "FOIST" you #$%&#%&*#$#%@# #$&^%ing @#$%^*$^
15:44 katsmeow-afk "One bit of advice: it is important to view knowledge as sort of a semantic tree � make sure you understand the fundamental principles, ie the trunk and big branches, before you get into the leaves/details or there is nothing for them to hang on to.�

16:07 katsmeow-afk if i choose to switch a IRFZ44 at 30khz, what sorta gate current will i need?
16:28 tsmeow-afk throws an url at rue and Tom : http://www.ebay.com/itm/181302088356

16:28 Tom_itx woops
16:28 Tom_itx ignore
16:28 katsmeow-afk whay must i ignore it!?!

16:29 Tom_itx my cut n paste is broke!!
16:29 tsmeow-afk looks at Tom repeating him
16:29 katsmeow-afk well, you weren't talking to me anyhow :-((

16:30 Tom_itx i don't get it!
16:30 katsmeow-afk btw, typical resistance on a long run can be an ohm, *easily*
16:30 katsmeow-afk basically, measure the length, multiply by two, look up the resistance in your handy databook
16:30 Tom_itx it's not long but i'm getting .9
16:30 katsmeow-afk all copper?
16:30 Tom_itx yes
16:31 katsmeow-afk if it's not long, that's high
16:31 Tom_itx maybe tighten all the screws?
16:31 katsmeow-afk if you have a dead short from hot to gnd, you don't want 60v on the gnd wire because it's an ohm back to the panel
16:32 katsmeow-afk look for corrosion under screws, generally white, maybe green or black
16:32 Tom_itx also drive a GND rod at that pannel?
16:32 katsmeow-afk also, watch out for daisey-chained gnd , two gnd under one screw, that's a no-no in my book
16:33 katsmeow-afk no, gnd rod may be required by code at times, but typical dry resistance of a copepr 10ft rod is well over 100 ohms
16:33 m_itx goes back out in the
16:34 katsmeow-afk usually, neutral and gnd get bonded together at the SE panel, which isn't such a good idea
16:34 Tom_itx Half of communications is listening, and you can't listen with your mouth.
16:34 katsmeow-afk in the cold? bring the poor panel inside!
16:34 Tom_itx that's what i was trying to post earlier
16:34 Tom_itx i thought it was good
16:34 katsmeow-afk i talk too much?
16:34 Tom_itx not related to you at all... just made sense to me
16:34 katsmeow-afk ok :-)
16:35 katsmeow-afk technically you canlisten with your mouth and eustacian tubes open
16:35 katsmeow-afk not very well tho
16:35 katsmeow-afk and peole look at you really wierdly
16:35 Tom_itx i think i'm gonna put a GFCI outlet on it
16:36 katsmeow-afk k, they are slow, but may help if the equipment is at fault
16:36 katsmeow-afk but if something else is going bad and yanking the gnd up, it prolly won't protect what's plugged intot he gfi
16:38 tsmeow-afk picked up a 2kw 120-240/120-240 isolation transformer for $25 on ebay, which is a damned fine buy,, you gotta wait to pounce at the right
16:38 katsmeow-afk smaller ones are more plentiful
16:46 katsmeow-afk http://www.ebay.com/itm/1KVA-1000VA-120V-240V-Isolation-Toroidal-Power-Transformer-p-n-AN-104115-/251781399338?pt=Vintage_Electronics_R2&hash=item3a9f57432a
16:49 katsmeow-afk i guess there was just a lot of them at the start of the crash a few yrs ago, and they are all sold off now
16:51 katsmeow-afk you could get a much smaller one, and float only the electronics, not the big 3 power transformers or any other cnc motors
16:52 Tom_itx ok there's clearly something going on here
16:52 Tom_itx i went back out and tightened all the screws in the sub pannel. now i'm getting 3 ohms across that oulet Neutral & GND
16:53 Tom_itx was getting .9? i think
16:55 katsmeow-afk check the neutral and gnd busses in the panelbox
16:55 Tom_itx the large slot on an outlet is neutral right?
16:55 katsmeow-afk the long holey aluminum bars
16:55 katsmeow-afk yeas
16:56 Tom_itx i've got some in this old house wired backwards
16:56 Tom_itx not on that circuit though
16:56 katsmeow-afk k
16:56 katsmeow-afk might be the gnd or neutral busses are floating off their connections to the powerco
16:57 katsmeow-afk specially if you have aluminum SE cable
16:58 katsmeow-afk i think when you torqued the screws in the gnd buss, you broke the last remaining connecton to the powerco
16:59 katsmeow-afk Tom?
17:00 katsmeow-afk if your panel has the gnd buss that's bolted only to the panel box, i suggest a heavy wire from it over to the neutral buss
17:01 katsmeow-afk and while you are at it, turn your (electric) oven and stove on high, and dvm between each hot *wire* and it's terminal on the main breaker
17:02 katsmeow-afk you should get essentially no Vdrop
17:03 katsmeow-afk i have seen main panels get loose, and actually melt the tar out of the panel, literally dripping tar down the wall
17:04 katsmeow-afk Al wire is supposed to have NoCorrode etc on it but most electricians don't apply it right
17:05 tsmeow-afk hopes Tom isn't getting f
17:05 Tom_itx was outside
17:05 katsmeow-afk k
17:05 Tom_itx need to go for a while now.
17:05 tsmeow-afk wrote a lot for
17:05 Tom_itx will get back to it later
17:05 Tom_itx i'll read it
17:05 katsmeow-afk k
17:25 Tom_itx i'll do some more testing
17:25 Tom_itx may be a while though
17:25 Tom_itx i'm gonna start at the main pannel and work my way out
17:26 Tom_itx in the mean time i'm gonna work on the control box itself
17:27 Tom_itx i checked several outlets in the house and was getting around 1 to 1.5 ohms across neutral and GND
18:12 Tom_itx just to be clear though, i just checked across my meter leads and am getting at least 1 ohm :(
18:15 Tom_itx ok that's fixed. now maybe i can measure something
18:32 Tom_itx now i get close to 0 on that outlet across neutral and gnd
19:23 katsmeow-afk "Sometimes it is the people who no one imagines anything of that do things that no one can imagine" - Alan Turing
19:24 katsmeow-afk "the imitation game" was posted online for maybe a few hours today before it got scrubbed
19:25 katsmeow-afk when i google for that quote, google lists only one hit
19:25 katsmeow-afk anyhoo, i can read the book
19:27 katsmeow-afk i believe i got the quote correct, if it is online in any other form, it's misquoted,,,,,,,,,,, that would be one hell of a signal to noise ratio
19:38 Tom_itx ok, digging a bit... there's a small chance i may have hooked the 5v to 24v
19:38 Tom_itx small but possible
19:39 rue_house hmm
19:39 Tom_itx i am going to eliminate that possible error this time around
19:39 Tom_itx all the 5v is going to come from one pcb rail
19:39 rue_house indeed
19:40 katsmeow-afk and be different color and different connectors?
19:40 Tom_itx i can't verify that's what happened but i can't deny it either
19:40 rue_house sounds like plug is good then
19:40 Tom_itx i think it is
19:40 rue_house dont forget to check the power bar and cords
19:40 Tom_itx i'm checking everything
19:40 katsmeow-afk if any futher doubt, consider a crowbar circuit
19:40 Tom_itx and i'm moving things around a bit
19:40 Tom_itx i don't know about them kat
19:40 rue_house I thought you had only hooked up serial to a board?
19:41 Tom_itx i had one sserial board wired up
19:41 Tom_itx it was fine
19:41 katsmeow-afk simple devices, 3 parts, if the 5v buss goes above 5.2v it shorts it to gnd and pops the fuses
19:41 Tom_itx it has 5v and 24v going to it
19:41 Tom_itx the 2nd one also can support both
19:41 rue_house isolation and crowbars
19:41 Tom_itx i may have overlooked the fact that it had 24v on it
19:42 katsmeow-afk crowbar it is then
19:42 Tom_itx i probably don't have those parts
19:43 katsmeow-afk think of it as a superduty latching zener with voltage foldback
19:43 katsmeow-afk i bet you do
19:43 katsmeow-afk scr or triac would be the easiest way to build, but a hefty bipolar works real fine too
19:44 Tom_itx http://store.mesanet.com/index.php?route=product/product&filter_name=common&product_id=230
19:44 Tom_itx all of my 5v will terminate there now
19:44 Tom_itx single wire to each point
19:45 Tom_itx it has a split buss for gnd and V
19:45 Tom_itx anything 5v will get it's power directly from there
19:45 katsmeow-afk do us a favor, paint all your green busses different colors for what they do, and label them
19:47 Tom_itx i'm gonna mark each side red and black on that one
19:48 katsmeow-afk it's *paint* , it's *cheap* , it beats blowing up a fpga and more expensive parts
19:48 Tom_itx i was debating putting one of those regulated supplies on it and superglue the pot once i had it set
19:49 Tom_itx because it has a led readout on it
19:49 Tom_itx it's the same smps as i'm using now but it's got a display
19:49 katsmeow-afk no, if yu go with more psus, put in an 8vdc supply to feed a 7805 on each pcb
19:49 Tom_itx you think hot glue would keep the pot in place?
19:50 Tom_itx not more, just a different one
19:50 katsmeow-afk whatever inside the cabinet will be forcing the pot to turn?
19:54 katsmeow-afk in 1983, slightly over 30 years ago, i built two 3U rack boxes to add circuits to a C64. I interfaced over 100 of those circuits to 120v signal lines to 3 Modicon controllers, i used a 7805 for each card in both card cages. I never had a power or a signal glitch problem.
19:55 katsmeow-afk and strangely in 1985 i was fired because i couldn't stand up, in violation of federal law, and haven't had a job since, because anyone who cannot stand isn't really human
19:56 Tom_itx vibration from the mill could cause the pot to turn
19:56 katsmeow-afk i thought the electronics box was on the wall, and the mill was on a table
19:56 Tom_itx the box sits on the cabinet the mill is in
19:57 katsmeow-afk if it's merely vibration, use hot glue, as you said
19:57 katsmeow-afk there is an electronics dope, similar to ordinary silicone sealer, but being more inert
19:58 katsmeow-afk it's usually dull red, i don't know why
19:59 katsmeow-afk awe crap, i did get the quote wrong, it's : "that do the things" , not "that do things"
20:01 rue_house https://www.youtube.com/watch?v=U-3_2UtTMtA
20:01 rue_house kat ^^
20:01 rue_house tech amusement
20:01 tsmeow-afk was conducting half a dozen threads of research, and stum
20:01 Tom_itx rue_house, does shielded wire go to GND or chassis GND?
20:01 rue_house chassis gnd typ
20:01 Tom_itx so i will tie it to the steel plate
20:02 katsmeow-afk Tom, in the real world, it's whichever works best, seriously, but not to both at the same time
20:02 Tom_itx the steel plate will have a ground wire going to the lug on the side of the box
20:02 Tom_itx they will both tie together at that lug
20:02 Tom_itx and that lug goes to GND on the power plug
20:02 katsmeow-afk k
20:02 Tom_itx is that reasonable?
20:02 katsmeow-afk yeas
20:04 Tom_itx how bit a fuse should i put on the 5v supply?
20:04 Tom_itx on the 5v side
20:04 rue_house I have to get your stuff shipped, grrr
20:04 Tom_itx i'm thinking 1.5 - 2A
20:04 katsmeow-afk i dunno how much curent you pull, can you measure it and add 10% ?
20:04 katsmeow-afk my stuff?
20:05 Tom_itx he printed me some din rail mounts
20:05 katsmeow-afk oh,, i'd be interested in how they flex
20:05 Tom_itx i got some from that place too
20:06 Tom_itx http://store.mesanet.com/index.php?route=product/product&filter_name=din+rail&product_id=227
20:06 Tom_itx all my boards are isolated now too
20:06 Tom_itx no more brass standoffs
20:07 tsmeow-afk mutes the youtube v
20:08 katsmeow-afk umm, those are aluminum rails
20:08 katsmeow-afk the clips on the parts are plastic
20:09 katsmeow-afk rue, does that guy really butcher a Saturn 5 pcb to see if the transistors in it still work?
20:10 katsmeow-afk knowing that after butchery, they won't work?
20:12 katsmeow-afk usetobe, you could simply put it on a analyser that would show standard ic part nmbers for whatever was on the pcb, and diode junctions and polarity
20:12 katsmeow-afk such analysers came for pc puter isa buss,, i have a baby one somewhere, lost the software after many crashes
20:42 rue_house they were really sparse DTL chips
20:43 rue_house reaaaly sparse
20:58 katsmeow-afk "Anti-social behavior is a trait of intelligence in a world full of conformists."
