00:00:00 <Ampera> I am
00:00:01 <Ampera> http://amperaa.net/cdn/Mansion.mp3
00:00:15 <Halcyon> ?
00:00:22 <Ampera> I'm not playing amazingly well, and doing a lotta experimenting, but it's at least something from my new reverb box/pedal
00:00:29 <Halcyon> Ahh
00:00:36 <Halcyon> I should get Mark to speak to you
00:00:41 <Halcyon> He teaches music
00:01:19 <Halcyon> Remote guitar lessons? Surely that could work
00:01:38 <Ampera> I don't think I'd learn well like that.
00:01:46 <Ampera> Most of what I need to know I'm learning as I go along.
00:02:00 * steve30 has to write an email
00:02:19 * Halcyon has to have a wank
00:02:23 <rust_collector> can someone come pick up this old piano I have here?
00:02:30 <steve30> I get too many people write to me wanting Walkmans repaired.
00:02:36 <Halcyon> rust_collector: Where is "here" ?
00:02:47 <rust_collector> south of norway, lol
00:02:56 <Halcyon> Dammit :P
00:03:14 <rust_collector> yeah, I doubt it would float
00:03:14 <Halcyon> Steve: Sounds like you could be a mixture of Techmoan and Louis Rossmann :P
00:03:24 <steve30> Halcyon, not got anyone to 'help' you?
00:03:39 <Halcyon> Why not turn it into a business
00:03:57 <steve30> I pondered that but i'm actually not very good TBH :D
00:04:07 <Halcyon> You *say* that
00:04:13 <rust_collector> what goes wrong in a walkman? I guess belts and dirt?
00:04:16 <Halcyon> But you would be surprised on how much more you know
00:04:38 <steve30> My website is more to showcase my bodge-repairs, and people take it a bit too seriously.
00:04:48 <steve30> rust_collector, yes, but also electronic faults
00:07:26 <rust_collector> I have been wondering, since I was a kid, what would it sound like, if you put a bunch of guitar pickups in a piano
00:18:42 <steve30> mmm, i feel better now i've had a coffee :)
01:19:00 Join: Nothing\ ([email protected]) to #EEVblog
01:22:24 <Nothing\> i got some calipers in the mail, just some cheap chinesium things, but they're surprisingly accurate, i tested em on a quarter
01:22:55 <Nothing\> my only complaint is the sliding action isn't terribly smooth, but i can mitigate that by putting my thumb right up against the slidey bit when i move it to stop it moving too far
01:23:30 <Nothing\> well, that and the fact that it looked for all intents and purposes like it was metal in the listing, but it's plastic, or carbon composite it says, but i haven't done a scratch test yet
01:23:36 <Nothing\> scratch and sniff test
01:42:21 <soulreap> hi
01:43:59 <Nothing\> hey soulreap how's it going?
01:44:18 <soulreap> going ok today you?
01:47:28 <steve30> I really should get some calipers
01:51:49 <Nothing\> i'm doing pretty good, thanks
01:52:04 <Nothing\> steve30: i've been telling myself i need to get a scale for ages, even if just a cheap one
01:52:14 <Nothing\> that is, a scale accurate to 0.01g
01:52:42 <Nothing\> i have a food scale somewhere but it's only accurate to 1 or 10 grams
01:53:47 <Nothing\> i bought a digital PH meter the other day, it was only $5 and comes with some PH standards, not a bad deal at all, even universal indicator is only 80 cents for a book of 60, as opposed to walmart selling a book of 50 or so for $9
01:55:26 <Nothing\> i'd really like to get a muon detector, i saw a practical engineering video where he set up a muon detector to detect cosmic rays and even had 2 detectors so you could figure out the direction they came from
01:55:37 <Nothing\> i guess some places sell them as kits now
01:58:07 <Nothing\> i also REALLY need to get something to put my ICs in, i wanna get one of those things with all the little drawers in it but i can't find them anywhere, don't even know what they're called so i can search for one but on the rare occassion i did find them, they were like $100
01:59:02 <Nothing\> as of now i just store them all in wee ziplock bags, or tubes if i'm lucky enough to get some and just put em in boxes from packages, which is fine but very disorganized
02:02:44 <soulreap> Nothing\: liek this draws here ? https://www.homedepot.com/p/Akro-Mils-64-Compartment-Small-Parts-Organizer-Cabinet-10164/203538935
02:03:11 <Nothing\> ooooh yes!
02:03:11 <soulreap> in bunings they sell them
02:03:12 <steve30> I just keep the IC tubes in plastic bags
02:03:14 <Nothing\> exactly those
02:03:27 <soulreap> and on ebay
02:03:28 <Nothing\> organizer cabinet, huh
02:03:34 <steve30> then keep the bags in cardboard boxes
02:03:38 <Nothing\> bunings huh, you an aussie?
02:03:46 <soulreap> yep :D
02:04:08 <Nothing\> nice, i only know what bunings is cuz the guy on extractions and ire mentioned it the other day in a video on obtaining acids in australia
02:04:14 <Nothing\> i'm canadian myself
02:04:28 <soulreap> oh cool
02:04:28 <Nothing\> but yeah home depots exist here so i should go check that out
02:04:47 <Nothing\> i keep telling myself i need to check out hardware stores for just whatever i may find useful, but i never get around to going to one
02:05:00 <Nothing\> i've been wanting to get a dremel for ages to facilitate tear downs
02:05:33 <soulreap> i got a dremmel to cut bits from a computer case
02:05:49 <Nothing\> i didn't even think i could use it to cut metal
02:06:07 <soulreap> yeh metal, plastic
02:06:34 <soulreap> i liek to play with computers
02:08:17 <Nothing\> it'd be useful for modifying project boxes as needed
02:08:46 <Nothing\> i was thinking if i ever needed to use a project box i wouldn't have any way to cut holes for connectors or what have you
02:10:19 <soulreap> i made design but idk if 1 or 2 antena can have more then 1 thing pluged in to it?
02:13:06 <Nothing\> i'm pretty sure an antenna can have more than one thing plugged into it, although i'm thinking for a receiver that's gonna cut the power of your signal in half
02:13:36 <Nothing\> maybe try it out on this
02:13:37 <Nothing\> http://www.falstad.com/circuit/
02:14:00 <Nothing\> i always test circuits on here to get an idea of what they'll do, it's not perfectly accurate but it's good for a rough idea of what'll happen
02:14:16 <Nothing\> it has an antenna component you can add
02:14:17 <soulreap> caqn i show you my design i made?
02:14:31 <Nothing\> yeah sure, but you've probably got more experience than i have in EE
02:14:48 <soulreap> https://usercontent.irccloud-cdn.com/file/kIcX7GdZ/My%20Sdr%20Box%20plan.jpg
02:15:03 <soulreap> i draw this up for sdr
02:15:08 <Nothing\> best i made for an RF circuit was an AM envelope detector i tried grounding to a window frame and didn't work lol
02:16:12 <Nothing\> nice
02:17:01 <soulreap> maybe have to modify it a bit if antena cant have so many pluged into it
02:17:18 <soulreap> or have antena ports for each on the back
02:17:21 <Nothing\> or maybe multiple antennas
02:17:28 <Nothing\> i dunno how that would work
02:17:43 <Nothing\> i don't see why it would be a problem to connect more than one thing to a receiver antenna
02:18:06 <Nothing\> other than the power being cut down for each connection
02:18:14 <Nothing\> or would it be raised?
02:18:21 <soulreap> hmm idk
02:18:27 <Nothing\> i'm confusing myself now, but rest assured it would do something to the power lol
02:18:30 <soulreap> all it has to do is listen
02:18:58 <Nothing\> yeah that's what i figure, if it's not actually doing anything actively it should be alright, it's not like there would be conflicting signals or something
02:20:30 <soulreap> yeh i think it could work
02:20:39 Quit: Halcyon ([email protected]) Ping timeout: 121 seconds
02:20:49 <soulreap> build it all in a grey project box
02:22:14 <Nothing\> i'd like to build something in a project box, or at least some permanent circuit, i still haven't made anything outside of a breadboard aside from a few very simple point to points i made when i first got into electronics
02:22:41 <Nothing\> it'd be nice to have permanent versions of circuits i use a lot so i don't have to keep building them every time i need them, like a clock generator
02:23:03 <soulreap> can make clock generator in minecraft with restone :d
02:23:22 <Nothing\> it'd be pretty simple, just get 3 inverters and feed the last inverter back to the first one
02:24:08 <Nothing\> assuming it takes long enough to turn on that you don't need to introduce any sort of delay into them, i know doing that in real life i had to put capacitors on the inverters to slow down how long it took to turn on, otherwise the frequency was too high
02:24:48 <soulreap> prety much soon as power is on all sdr is tuned on and on usb hub ready to use
02:25:03 <Nothing\> you should check this out if you like playing with digital circuits, it's much easier to build stuff than in minecraft :P
02:25:05 <Nothing\> http://www.cburch.com/logisim/
02:26:07 <soulreap> ooh yeh i played with some in linux
02:26:12 <soulreap> some programs liek that
02:26:28 <Nothing\> i really like logisim cuz there's no limit to how big you can make your circuits, it lets you make sort of sub circuits, like an IC, so you can have as many levels of abstraction as you need
02:27:04 <Nothing\> yeah i've been playing with this since before i even knew what a capacitor was
02:28:25 <Nothing\> it gave me the idea to one day build my own computer, but since i took up electronics that goal actually seems attainable now
02:28:39 <soulreap> ooh me and my uncle we got a old amplifier working once from the tip and it was going for liek 1 hour and it was good then BANG it went and stink the room out it wa sa big bang and it exploded capastiros inside it
02:29:02 <Nothing\> tsk tsk, should always check the caps on old electronics lol
02:29:07 <Nothing\> live and learn, right?
02:29:18 <soulreap> yeh
02:29:37 <Nothing\> there was this fairly new NIMH battery charger i tore down where one of the beefier electrolytics was buldging
02:29:57 <soulreap> they was Big ones too size of a coffe cup
02:30:06 <Nothing\> yikes
02:30:31 <Nothing\> i've been thinking about how dangerous capacitors really are, i think a lot of the danger is probably overstated
02:31:02 <Nothing\> they might hurt you, but i don't think it's gonna kill you, at least not very easily
02:31:03 <soulreap> yeh my laptop charger made 3 big bangs last year and stink my room out
02:31:04 <Nothing\> especially since it's DC
02:31:28 <Nothing\> i don't think i've ever had electronics literally explode, or even smoke
02:31:37 <soulreap> i hav :D
02:31:53 <soulreap> my frend last week had his computer catch fire
02:32:05 <soulreap> https://usercontent.irccloud-cdn.com/file/DyRcumPd/IMG_01691.png
02:32:11 <soulreap> this is his pic he send me
02:32:14 <soulreap> of bit that burnt
02:32:37 <Nothing\> worst i remember doing was i spent a night playing with MOSFETs, which you only need a pull resistor on the gate, nothing to limit current since there's no current, but then i switched to playing with BJTs and forgot to put a current limiting resistor on the base and connected it directly to 9v, it sizzled promptly, there was no magic smoke but it sure did smell
02:32:51 <Nothing\> yikes @ computer on fire
02:33:17 * Nothing\ googles the pinout of molex connectors to see which wire burned
02:34:08 <Nothing\> +12v
02:34:33 <soulreap> yeh he says it fried his 12v rain in his psu too and also pcie raisers
02:34:42 <soulreap> rail
02:34:46 <Nothing\> i wonder what happened, a short maybe?
02:35:12 <Nothing\> actually if a capacitor died, those basically turn into jumpers when they die so that would cause a short
02:35:17 <soulreap> idk but i google searched moled bunrt and lots had same problems with even other conectors
02:35:39 <Nothing\> at least with some modes of failure they turn into jumpers
02:36:32 <Nothing\> heh i was thinking the other day, who needs puzzle games when you've got EE
02:36:46 <Nothing\> it's like a real life logic/puzzle game
02:36:54 <soulreap> yeh
02:37:24 <rust_collector> try car design, cost reduction, and engineering.
02:37:27 <soulreap> i brb i get redy for bed
02:37:31 <Nothing\> except you actually get tangible rewards in the form of electronics, rather than just some token point system or psychological equivalent of a dog treat
02:37:42 <Nothing\> soulreap: lol it's noon here
02:37:47 <Nothing\> weird time traveling aussies
02:38:15 <Nothing\> rust_collector: yeah i've recently been appreciating optimizing circuits for efficiency
02:38:37 <Nothing\> especially since i run my circuits off of shitty batteries, i have to make every mAh count
02:39:56 <rust_collector> hmm, now that you mention mAh, I got a somewhat defective forklift charger from work. I should look inside that thing, and see what happened.
02:40:21 <Nothing\> hrm i should break out some op amps, i'm so excited now that i've figured out how to generate a negative rail so easily with 7660s, i've always avoided op amps for the most part because i hated the logistics of trying to make a dual rail supply from a battery
02:40:25 <rust_collector> It tends to work, but there is something big and heavy rattling around in it, lol
02:40:39 <Nothing\> maybe a piece of metal that caused a short?
02:40:54 <rust_collector> yeah, something like that.
02:41:08 <Nothing\> you might even be able to salvage some parts from it
02:41:38 <Nothing\> lol when i first got into electronics i didn't know where to get parts easily, so i wound up desoldering stuff from whatever i could find
02:42:04 <Nothing\> transistors were like, the holy grail for me, but all i could ever find was surface mount, and the second you take a soldering iron to one of those they pop
02:42:37 <Nothing\> i tell you when i finally got a hold of 2 to-92 transistors and made my first astable multivibrator, i was sooo happy
02:43:08 <rust_collector> I do take things apart, but I usually end up with a big pile of parts that are not ideal for anything I want to do
02:43:25 <Nothing\> i started buying stuff on amazon but it was so overpriced and they didn't have any ICs so all i could get was passives or transistors, so i resorted to trying to recreate IC circuits using RTL with the transistors lol
02:44:05 <Nothing\> haha yeah tell me about it, i've got a drawer full of random boards i pulled out of things, i have no idea why i kept them cuz most of them use ASICs anyways so it's not like i can even reverse engineer them
02:44:44 <Nothing\> stuff from like, a scanner, or a vcr/dvd combo
02:45:30 <rust_collector> I do have some boards that came from a russian fishing boat, that was here... 15 or so years ago, to have some work done. I have no idea what the boards did, but they look pretty cool, in their won way
02:45:40 <rust_collector> own
02:46:38 <soulreap> i am back
02:46:41 <rust_collector> big chunky parts, and it looks like they hand painted the colors on them
02:46:54 <soulreap> i sleep soon
02:47:40 <Nothing\> wb soulreap
02:47:54 <soulreap> ty
02:47:56 <Nothing\> rust_collector: heh i've always wanted to get some soviet era TTL chips
02:48:12 <Nothing\> they've got ema ll over ebay
02:48:31 <Nothing\> unfortunately ebay doesn't like my visa debit card so i can't order on there
02:48:47 <soulreap> i want to get oold valve amp
02:49:04 <Nothing\> i dunno about old ones, but they sell new ones fairly cheap
02:49:21 <Nothing\> i think it was dave tore one down a while back in one of his videos
02:49:22 <soulreap> oh
02:49:43 <rust_collector> heh, the one where the valved did almost nothing, except look cool?
02:49:44 <soulreap> i like daves videos
02:49:51 <Nothing\> rust_collector: lol yup
02:49:55 Join: AndrevS ([email protected]) to #EEVblog
02:50:03 <Nothing\> soulreap: me too, but they haven't been as good lately for some reason
02:50:14 <Nothing\> ever since he moved into the new lab, i dunno if he's just been too busy or what
02:50:28 <Nothing\> but it's not like there's a lack of old content to go back and watch
02:50:38 <Nothing\> hell i musta watched his video on op amps about 5 times
02:50:48 <soulreap> yeh his old vids more beter
02:50:51 <rust_collector> with moving the lab, flooding the lab, and maybe doing real things... I guess there is not much time left
02:50:57 <Nothing\> i love his fundamentals fridays videos
02:51:06 <soulreap> i like when he opens mail
02:51:08 <Nothing\> rust_collector: that's what i figured, so i haven't been too pissy about it
02:52:23 <Nothing\> soulreap: yeah mailbag videos are nice but he always seems to skim over the interesting packages saying he spends too much time talking about singular items and needs to do separate videos for them, but then he'll spend half a video going on about something like a crappy learning kit made by some indian company who thinks cartoon mascots are ideal for teaching about electronics
02:53:21 <soulreap> oh yeh
02:53:27 <Nothing\> i briefly considered making some sort of basic learning kit to try my hand at product design/selling but considering they're a dime a dozen i don't think there would be any money in it
02:53:45 <Nothing\> more realistically i think i'd be better off just buying stuff in bulk from ali express and reselling it on amazon
02:54:28 <soulreap> is amazon safe to buy from ?
02:54:36 <Nothing\> oh yeah, ali express too
02:54:42 <Nothing\> i've never had problems with either
02:54:50 <soulreap> oh xool
02:54:54 <soulreap> cool
02:54:55 <Nothing\> actually ali express has a nice refund policy, no questions asked
02:55:16 <Nothing\> once or twice i had to file a claim for packages that never arrived and they gave me my refund immediately, no hassles or anything
02:55:25 <Nothing\> then the package wound up coming anyways lol
02:55:28 <soulreap> oh cool
02:56:12 <Nothing\> ali express has proven a great place to get electronic components, so long as i don't care about whether they're legit or counterfeits
02:56:22 <soulreap> i had someone steal box from mums front door
02:56:24 <Nothing\> when i looked more closely at my chips recently i realized a lot of them are counterfeits
02:56:37 <soulreap> now we put cameras
02:56:49 <Nothing\> yeah i don't get why they just leave the package on somebody's doorstep like that, it's just asking for it to be stolen
02:57:15 <soulreap> and was my package too :/
02:57:38 <Nothing\> apparently in the UK, if you're not home, by default they'll leave the package with one of your neighbours, unless you fill out a form that specifically tells them not to do so
02:57:52 <soulreap> ooh
02:57:57 <Nothing\> you'd think it should be the other way around
02:58:05 <Nothing\> since not everybody trusts their neighbours by default
02:58:32 <soulreap> yeh i think here thry used my wifi
02:58:50 <soulreap> so i changed pasword
03:00:31 <soulreap> funy they steal my package they got nothing they can use
03:02:01 <soulreap> i have to sleep now
03:02:07 <soulreap> night all
03:02:19 <rust_collector> you ordered the package, so maybe they assume someone else will pay for it too?
03:02:59 <soulreap> oh i had already paid tho
03:03:50 <soulreap> ok k niight
03:06:30 <rust_collector> yeah, you paid, and now someone else can pay too
03:06:51 <rust_collector> probably less than you, so he won't tell anyone
03:11:51 <steve30> Nothing\, To opt out of neighbour delivery, you have to use one of these stickers on your door/letter box
03:11:52 <steve30> https://www.flickr.com/photos/36651585@N04/41163845384/in/dateposted-public/
03:13:16 <Nothing\> steve30: that's right
03:13:29 <Nothing\> i knew there was something you had to do to specifically let them know you opted out
03:13:47 <steve30> Doesn't apply to couriers though, only Royal mail
03:15:28 <Nothing\> man no wonder i thought these surplus radioshack photodiodes i got were bunk, i could never measure anything from them but using my good multimeter i just got a whopping 0.03ua out of it
03:15:45 <Nothing\> holding it right up to a 100w lightbulb
03:16:08 <Nothing\> no wonder my crappy meter couldn't pick anything up
03:20:49 <rust_collector> how much do you get out of a regular led?
03:21:09 <Nothing\> i'm not even sure i could measure that, lemme see
03:21:47 <Nothing\> i guess it's not really the current that matters though but the voltage, at least the way i figured to do it is using the voltage to bias a resistor
03:21:52 <Nothing\> er transistor
03:23:50 <Nothing\> yeah i couldn't measure any current from an LED but i did get 0.06v
03:24:15 <rust_collector> interesting
03:24:48 <Nothing\> it's neat when you think about how many electronic components can be used both ways like that
03:25:22 <Nothing\> like a dc motor can be used to generate power, an LED can be used as a photodetector, and a photodector as an LED
03:25:39 <Nothing\> actually steve mould made a video where he ran a ton of current through a solar panel and got it to give off IR
03:26:10 <Nothing\> i thought that was surprising, you always hear of LEDs being used as a photodiode but never the other way around
03:26:33 <Nothing\> or speakers can be used as microphones, there's another one
03:33:06 <rust_collector> once again, I am trying to make wok, without a wok. It is never great
03:37:39 <Nothing\> hrm i was just thinking, using an lmc7660 for the negative rail of an op amp is probably gonna be really noisy, especially on a breadboard
03:37:48 <Nothing\> maybe i should use a separate breadboard for it
03:39:06 <rust_collector> maybe build a small "split supply unit" board, that you can plug into anything you work on?
03:39:42 <Nothing\> actually that's a great idea
03:40:36 <Nothing\> or even if i just got at tiny breadboard for it, these things are incredibly simple the only need 2 capacitors and that's it, more simple than even a 555
03:58:11 <DHess_US> It's usually not a problem. A simple RC or LRC filter can remove the high freuency noise and the operational amplifier's power supply rejection will handle the rest.

05:14:51 <WebChatUser> Hey guys
05:19:12 <DHess_US> Straw is cheaper; grass is free.
05:32:08 <WebChatUser> I don't know if anybody is around, but I just had a quick PCB design question, and was hoping somebody could point me in the right direction.
05:33:39 <WebChatUser> but I'm just designing a 6 layer board. Its all pretty low-speed.
05:34:24 <WebChatUser> And I read that you should just put copper pours/fills in every layer to keep the board from warping/twisting
05:34:33 <WebChatUser> Which makes sense enough
05:34:52 <WebChatUser> But I'm wondering if I should leave all that copper "floating" or if there is a good reason to tie it ground?
05:37:22 <Nothing\> well that's weird, i think i just got burned by vinegar
05:37:49 <Nothing\> i was taking the foil off of a new bottle of vinegar and when i touched the part that was on the inside my finger started burning really bad
05:38:22 <Nothing\> i rinsed it off since i was right next to the sink, i'm thinking maybe some of it evaporated off and the acetic acid was more concentrated somehow, i dunno
05:39:03 <Nothing\> like maybe some concentrated acetic acid condensed on the foil, or maybe i just imagined the whole thing, i dunno
05:39:12 <Nothing\> it's really confusing
05:40:33 <Nothing\> DHess_US: that's good to know, when i tried running the circuit i did indeed get fluctuations on my output voltage at the same frequency i was pumping the 7660 at so there was definitely noise
05:41:00 <Nothing\> then again i'm sure having no bypass caps didn't help lol
05:41:51 Join: Bluenote ([email protected]) to #EEVblog
06:16:22 <DHess_US> You still need to filter the charge pump output to some extent.
06:16:45 <DHess_US> WebChatUser, concentrated acetic acid is a serious burn hazard.
06:17:00 <DHess_US> err, I mean Nothing\
06:17:34 <DHess_US> WebChatUser, floating copper fills or floating anything is usually a bad idea. Copper fills are contraindicated around high impedan ce circuits.
06:18:43 <WebChatUser> hmmm
06:18:47 <T3sl4> WebChatUser: more that the amount of copper on layers at the same height should be the same
06:19:04 <T3sl4> if you have a lot of wasted space on the inner layers, consider just doing 4 layers instead?
06:19:27 <T3sl4> otherwise, low density routing on them is fine, it's just added fab cost
06:20:14 <T3sl4> i almost never pour all layers in a 4+ layer design, just because it's such a pain placing vias around the components and traces on all layers
06:20:43 <T3sl4> since, floating copper isn't such a good idea, and you get the best advantage with stitching vias tying everything together
06:21:04 <WebChatUser> Thats a fair point, this is pretty much the only low-density layer, however. There are quite a few power pours and there are some thermal limitations.
06:21:32 <WebChatUser> DHess_US I had to google what contraindicated means
06:22:26 <DHess_US> The copper has a different coefficient of expansion than the board material so it needs to be roughly uniformly distributed to prevent warping.
06:22:58 <WebChatUser> DHess_US when you say "ce circuits" does that refer to common emitter circuits?
06:23:02 <DHess_US> There are also heat capacity issues when soldering where one part of the board with lots of copper will be cooler or take longer to ehat up.
06:24:43 <DHess_US> It refers to any circuit which is not using transmission lines. So for instance while a RF amplifier will likely be terminated into a low impedance transmission line at the input and output, individual circuit nodes within the amplifier will *not* be low impedance and placing them in a ground plane environment causes excessive parasitic capacitance which will have a large effect on operation.
06:25:24 <DHess_US> So for example you cut away the ground plane near the inverting input of an operaitonal amplifier and any parts connecting to it.
06:26:27 <DHess_US> Or cut the ground plane away from the summing node of any inverting amplifier.
06:28:20 <WebChatUser> Hmmm. Are you talking about removing part of the ground pour below the chip itself?
06:28:33 <WebChatUser> The op-amp/in-amp or what have you
06:29:04 <DHess_US> That is often what is done. But it is just as important to remove it around parts and traces which connect to the inverting input or summing node.
06:30:08 <DHess_US> It applies to any high impedance point to minimize stray capacitance.
06:30:51 <WebChatUser> Interesting. Wow there is so much about high-speed/precision design that I don't know about.
06:31:10 <WebChatUser> It seems hard to test this kinda stuff with "at home" lab equipment.
06:31:37 <DHess_US> parasitic capacitance at a summing node reduces phase margin and may actually cause oscillaition. There are ways to compensate for it but the first step is to minimize it.
06:32:31 <DHess_US> It's a problem with fast parts but fast only extends to 10s of MHz and sometimes even lower.
06:34:41 <WebChatUser> Yeah I mean I think the fastest bus we have on the board is MAYBE a 10Mhz data & clock line
06:35:13 <DHess_US> It usually is never an issue with digital logic because impedances are always low.
06:35:57 <DHess_US> Which is one of the reasons digital designs are prefered.
06:36:32 <DHess_US> But that gets back to floating copper islands. They can still couple between circuits if not grounded.
06:38:42 <DHess_US> They also are not good for EMI.
06:41:14 <DHess_US> The general rule is no floating copper islands.
06:41:29 <DHess_US> Offhand I don't know of any examples where floating copper is a good idea.
06:41:52 <WebChatUser> Ok, this is very usefuol
06:41:55 <WebChatUser> *helpful
06:42:01 <DHess_US> Ok, I know of one example. Some high voltage capacitors are fabricated with floating conductive plates.
06:42:51 <WebChatUser> That seems like a pretty edge case from where I'm sitting :P
06:43:08 <DHess_US> Yea, I don't think it applies. It might apply to high voltage circuits.
06:43:39 <WebChatUser> Hahaha it seems more like physics at that point
06:44:29 <DHess_US> My hypothesis is that the floating plates in a capacitor make the electric field in the dielectric more uniform preventing breakdown in small areas.
06:45:15 <DHess_US> This is why air bubbles in a high voltage insulator are bad. They make the electric field non-uniform.

07:07:57 <DHess_US> "hullo droogs" would have been less confusing.
07:09:31 <rust_collector> hoi!
07:09:38 <rust_collector> mijn kont jeukt
07:09:44 * T3sl4 serves DHess_US a nice tall cool glass of whole milk
07:09:52 <rust_collector> And that is all the dutch I know
07:10:05 <Ampera> Привет, друзья
07:10:23 * Ampera takes the rest of the jug from T3sl4 and chugs
07:11:03 <Ampera> welp Joe Biden's running
07:11:13 <Ampera> he's also entered into the primaries for a democratic nomination for president
07:11:17 <rust_collector> hope someone is filming that
07:12:02 <Ampera> I wouldn't worry about film, it's a bit more than a film, it's more like a drool running from the collective minds of his supporters into their sippy cups
07:12:30 <rust_collector> meh, as long as I can see that guy run, that is ok
07:13:28 * T3sl4 scritches steve30
07:13:39 <DHess_US> I keep getting Joe Biden confused with Bernie Sanders.
07:13:49 <Ampera> DHess_US, he probably does too
07:14:14 <Ampera> I hate all of the options available. I kinda liked Bernie, and when I go to vote, that's probably my guy, but eh
07:14:23 <rust_collector> joe b is not THAT old, is he?
07:14:32 <steve30> :D
07:14:55 <Ampera> JB 76 BS 77
07:15:05 <rust_collector> ok, close enough
07:15:51 <Ampera> joe bindin up young women in a truck stop bathroom
07:16:07 <Ampera> is anybody gonna even be running for GOP nomination
07:16:23 <T3sl4> no, fuck that, they want to stick with the known crazy
07:17:11 <Ampera> T3sl4, they don't want some new guy coming in and actually gaining some respect from congress, and to make reasonable decisions that actually get executed
07:18:08 <Ampera> Did the US army engineers (or whoever is gonna end up doing it) end up building the wall yet, or start, or is it just another one of these things where it's hyped up forever but nobody's actually stupid enough to sink 26 billion dollars into a political statement
07:18:45 <DHess_US> After what happened to Bernie, why would anybody have anythign to do with the DNC or bother voting in the Democratic Primary? It is just a scam.
07:19:02 * steve30 lies down on T3sl4's desk
07:19:08 <DHess_US> Vote for whoever you want but they pick who wins ahead of time? Fuck that.
07:19:15 <Ampera> DHess_US, because the GOP isn't exactly offering us candidates that we particularly like
07:19:32 <DHess_US> Again, you aren't represented by the DNC either.
07:19:35 * T3sl4 puts a new Digi-Key box beside his keyboard to distract steve30
07:19:40 <DHess_US> I was talking about he Primary and not general eleciton.
07:19:45 <Ampera> I mean
07:19:49 <DHess_US> I did say "primary", didn't I?
07:20:00 <steve30> ooh, components to nibble on :)
07:20:02 <Ampera> I don't see how that makes a difference, but I'm not entirely sure what you're getting at
07:20:30 <DHess_US> The DNC Primary election was rigged. The votes were irrelevant. They admitted it. So why bother participating?
07:20:56 <Ampera> because the mindset of the system is too flawed to vote just leads people who aren't smart enough to understand that to vote
07:20:57 <DHess_US> And Bernie went along with it. I suspect he knew all the time. So fuck him also.
07:21:11 <T3sl4> hey! i need those for the project!
07:21:11 <DHess_US> Great, now you have affirmed to the cat that it is God and you are its worshipper.
07:21:14 * T3sl4 swats
07:21:15 <DHess_US> So what? Their votes were irrelevant?
07:21:20 <Ampera> I ain't happy about it either, but there's basically nothing you can do about it
07:21:22 <DHess_US> irrelevant!
07:21:29 <T3sl4> DHess_US, a god needs a throne, obviously
07:21:34 <DHess_US> Sure there is. Stop supporting the DNC.
07:21:40 <Ampera> and support who, the GOP?
07:21:47 <Ampera> they don't have good candidates
07:22:13 <DHess_US> The GOP isn't an alternative to the DNC. DNC! "Democratic National Comittee"
07:22:25 <steve30> I think this topic has come up before, but are cats ESD safe?
07:22:30 <DHess_US> You know, the guys who picked the winner of the DNC Primary Election ahead of time and fucked Bernie's voters.
07:22:51 <Ampera> the DNC is the democratic party
07:23:00 <DHess_US> And then Bernie went along with it. How well did that work out?
07:23:00 <Ampera> they run it
07:23:03 <T3sl4> they can be: https://i.imgur.com/Nmemvo4.jpg
07:23:07 <DHess_US> So get someone else to run it.
07:23:20 <Ampera> that's not how it works
07:23:29 <Ampera> the parties are for, I believe, all intents and purposes private organizations.
07:24:01 <Ampera> with their own membership system, and their own private system for selecting candidates. They aren't connected to the actual election, and aren't part of the government, so it's allowed.
07:24:02 <DHess_US> I'm not advocating for the GOP. There has been no reason to trust them since President Ford. I'm advocating supporting an alternative to the DNC.
07:24:14 <DHess_US> No
07:24:39 <DHess_US> They are ESD safe neither as a source nor as a load.
07:24:44 <Ampera> there is no alternative to the DNC in the same way you can't just replace all the shareholders of an entire company just because some employees aren't happy with the command decisions
07:24:52 <DHess_US> Exactly. And since the DNC does not represent the voters who vote in the DNC Primary election, fuck them. The Democratic voters get nothing out of it.
07:25:18 <Ampera> understood, my point is that it's not going to be fixed any time soon
07:25:28 <DHess_US> I can stop dealign with the company. I can stop dealing with people like Bernie who know better, say they object to it, and then go along to support it.
07:25:39 <Ampera> DHess_US, what else was he gonna do?
07:25:52 <Ampera> If the big brass say you don't get it, you don't get upset and cry about it
07:25:55 <DHess_US> He could have not supported what the DNC did.
07:25:56 <Ampera> that's how they womp you on your ass
07:26:02 <DHess_US> Which is why I think he was in on it the whole time.
07:26:17 <DHess_US> Bernie lied to his supporters. Fuck him.
07:26:19 <Ampera> don't bite the hand that feeds you
07:26:31 <DHess_US> Yes, feeds Bernie. Not feed Bernie's supporters.
07:26:47 <Ampera> point being don't get upset at the DNC if you want the DNC's help to become president.
07:26:59 <DHess_US> Bernie's supporters where the "product" that Bernie supplied to the DNC.
07:27:16 <Ampera> in exchange for the chance at all to become president
07:27:32 <DHess_US> I dont' want the DNC's help to become presidnet. I want a president who represents me and the DNC is not capable to supplying that.
07:27:54 <Ampera> The GOP are
07:27:59 <DHess_US> The DNC cannot supply *anybody* to represent me. So why should I deal with them at all?
07:28:05 <Ampera> afaik they don't have the internal party structure to just decide, eh, whatever
07:28:13 <Ampera> because it's either them, the GOP, or nobody
07:28:22 <Ampera> welcome to the US presidential election system
07:28:30 <DHess_US> I don't care how they decide if they lie about what they provide and do not supply representation.
07:28:48 <Ampera> good man, support third parties and independent candidates
07:29:04 <Ampera> I'll see you in a few hundred years when significant numbers of people give a crap
07:29:19 <DHess_US> The GOP at least provided some sort of representation as poor as it was which just makes the result hillarious.
07:29:52 <DHess_US> I'm not hypocritcal enough to help the DNC cut my own neck.
07:30:06 <Nothing\> hrm DHess_US i was gonna say something to you earlier while you weren't here but now i can't remember what it was
07:30:08 <Ampera> All I can tell you, is useless or not, betrayed or not, I'm registering democrat in 2020, voting in the primaries, and we'll see what happens from there
07:30:20 <DHess_US> If they are going to hang me anyway, I might as well do something so they have reason to hang me multiple times.
07:30:29 <Ampera> because it's either them, I vote for Trump, or I don't even bother
07:30:33 <Nothing\> hrm i'm not sure
07:30:59 <Ampera> DHess_US, I think you have the right attitude, one I would share with you if it were a system where those complaints actually matter.
07:31:21 <DHess_US> They mattered in the past. Given the right black swan event, they will matter again.
07:31:29 <Nothing\> hrm no clue what it was
07:31:29 <Ampera> The Democrats are their own private party and organization, in the same way any other golf club or homeowner's association would be.
07:31:47 <Nothing\> Ampera: so, how did obama get in then?
07:31:48 <Nothing\> :P
07:31:54 <DHess_US> But there is zero reason to support the DNC when their intention is to kill me. Fuck them.
07:31:55 <Ampera> If they want to do whatever, there's nothing we can do to stop them. If you suggest a change in leadership, good luck staging that coup.
07:32:05 <Ampera> Nothing\, either by a legit primary or by them fudging the votes
07:32:20 <Ampera> DHess_US, so then who are you registering with
07:32:22 <Nothing\> the electoral vote system is flawed anyways
07:32:31 <Nothing\> trump never did get the popular vote
07:32:31 <Ampera> Nothing\, this is an unrelated voting system
07:32:33 <Nothing\> oh
07:32:41 <Nothing\> then in that case i'll play the cannuck card
07:32:42 <DHess_US> Who cares? As you point out, there are no alternatives. Actually there are but we can't discuss it.
07:32:44 <Ampera> In the US, anybody that meets the requirements can run for president.
07:32:57 <Nothing\> Ampera: and with a ton of money
07:33:03 <Ampera> You can run with or without a party, and de jure, that's as simple as it gets.
07:33:07 <Ampera> De facto, as you said, you need money
07:33:13 <Ampera> and it's the parties with their sponsors that get the money
07:33:25 <DHess_US> The only thing flawed about the Electorial College is plurality which is the same flaw in almost all US elecitons.
07:33:29 <Ampera> and if the sponsors don't like a candidate, they are probably the ones that can pull the plug.
07:33:53 <DHess_US> Actually, you cannot. They pretend that you can but it doesn't work that way.
07:34:16 <Ampera> I understand the reason for the electoral college, as it treats the US as a nation of united states, and not homogenous, to which this is an effectively (pre cheating) Eurovision Song Contest voting system
07:34:27 <DHess_US> I worked election security for a couple years in California. They didn't even bother counting third party votes. I watched them throw third party ballots in the trash and they confirmed it.
07:34:45 <Ampera> DHess_US, doesn't surprise me
07:34:56 <DHess_US> Which was ammusing later that day when they reported results for votes which were never counted.
07:35:02 <Ampera> that's highly illegal on the grounds of some treasonous whatever, but nobody cares
07:35:20 <DHess_US> And of course the results were always just under the number required to be automatically enrolled in the next eleciton.
07:35:58 <Ampera> but regardless, in terms of the electoral college system, I personally dislike it, but do not blame others for liking it.
07:36:09 <DHess_US> Oh, everybody there knew it except me until I asked. Every level of government was aware. There was nobody with any authority to advise about it who did not already know.
07:36:11 <Ampera> I might see the US as more homogenous as others.
07:36:33 <Ampera> DHess_US, again, laws don't mean shit if nobody cares to enforce them.
07:36:51 <Ampera> It's illegal to name a pig Napoleon in France, but I doubt anybody has been brought up on those charges in recent times.
07:36:54 <DHess_US> Who was going to enforce them? The city, county, or state DAs? Ha!
07:37:05 <DHess_US> And a private citizen has no standing to enforce them.

08:57:58 * Halcyon prods Ampera
08:58:09 <Ampera> Hi Halcyon
08:58:29 <Halcyon> How are you?
08:58:31 <Ampera> DHess_US, that's either me or someone who, through some incredible fault of human intelligence, education, and logic has decided that they wish to be me.
08:58:50 <Ampera> somewhat tired, I just went to Applebee's and ate a load of food
08:59:29 <Halcyon> :)
08:59:38 <Halcyon> I'm about to go get a haircut
08:59:57 <Ampera> Halcyon, I haven't had one of those in about a year
09:00:01 <Ampera> so I got long ass hair
09:00:13 <Halcyon> You should trim your ass hair
09:00:28 <Halcyon> I was going to ask quickly before I go....
09:00:34 <Ampera> right as I sent that I regret not saying longass so you and your fat cheeky ass couldn't come over here and make that obvious obvious joke
09:00:53 <Halcyon> Would you be interested/have time to help me out with my company's website? You're good with all that sort of thing and figuring out things you don't know.
09:01:08 <Ampera> as in designing the website or maintaining it
09:01:47 <Halcyon> Having a play around with re-designing it. I would give you access to CPanel. Currently we are using a Wordpress template (it was thrown up there as a placeholder until we go something better). But it needs a revamp.
09:01:57 <Halcyon> Happy to stick with Wordpress or look at alternatives
09:01:59 <Ampera> *hiss* CPanel
09:02:17 <Ampera> Yeah I could look into some options.
09:02:17 <Halcyon> I agree, but it's all we have to work with at this stage
09:02:42 <Halcyon> I'm not a web designer or don't really understand a lot of the backend stuff, so I don't know what can be done and what options we have
09:02:51 <Halcyon> But yes, there will be some designing that needs doing as well.
09:02:53 <Ampera> To be level with you I don't have a good relationship with the WWW, and my last attempt wasn't that fruitful.
09:02:58 <Halcyon> But only if you're interested in helping us out :)
09:03:08 <Ampera> However I do have a good working understanding of backend structures, maintaining servers, and getting those systems operational.
09:03:21 <Ampera> So if my skills happen to help you, or I can manage to acquire ones that do, I'm totally onboard.
09:03:33 <Halcyon> Well maybe if we can look at alternatives to Wordpress and see if it can be installed on the services we have currently?
09:03:38 <Halcyon> As I said, I don't know what's possible.
09:03:58 <Halcyon> Will you still be around in about an hour?
09:04:59 <Ampera> if you want me to be
09:05:56 <Halcyon> I'll hit you up when I get back, I have to go now, but I won't be long. We'll talk more then and I'll give you the creds.
09:06:06 <Halcyon> If you're not around, there is always tomorrow/later tonight.
09:07:03 <Ampera> I'll be here
09:07:04 <Ampera> ciao
09:13:29 <DHess_US> Ampera, can't be you. You're here and they are there. Unless you can be in two places at the same time.
09:13:56 <Ampera> DHess_US, with enough lube anything can be a dildo if you're brave enough
09:14:22 <DHess_US> Or unless they can be in two places at the same time. What have you done with the real Ampera?
09:14:40 <Ampera> DHess_US, trust me, wherever the real Ampera is, he's in a much better place
09:14:46 <Ampera> I just wish I was him so I could be in that better place
09:15:08 <DHess_US> Got impatient and the rain stopped so I fixed car.
09:15:42 <Ampera> I'm listening to ELO
09:15:56 <DHess_US> Next you will listen to ABBA.
09:16:18 <Ampera> ABBA's alright, but they're not as nice as ELO
09:16:26 <DHess_US> I had the Xanadu soundtrack on LP. Twice since I wore one out.
09:16:42 <Ampera> ELO and ABBA are nothing alike imo.
09:16:50 <DHess_US> Except in era.
09:16:53 <Ampera> ELO has way more variety, and they have 80's songs.
09:16:58 <DHess_US> They aren't *that* far apart.
09:17:35 <Ampera> Its just a different style. ABBA is closer to disco, and while ELO had disco, they were more Chicago, but if it were a rock group.
09:18:04 <Ampera> and then sort of went kinda mid-80's synthpop/new wave after I believe Time
09:18:26 <Ampera> I'm just dashing around songs, but I'm currently listening to Showdown.
09:18:44 <Ampera> As for Xanadu, my two favourite songs on that soundtrack is All Over the World, and I'm Alive.
09:20:19 <DHess_US> I'd put ABBA and ELO in the same folder if I did such things.
09:20:45 <DHess_US> Hmm, I don't have the Xanadu sountrack on digital. I should fix that.
09:20:55 <Ampera> DHess_US, I get it all off YouTube
09:21:07 <Ampera> I'd put The Beatles and ELO in the same folder
09:21:28 <DHess_US> See, the trick there is that I don't particularly like the Beatles.
09:21:44 <Ampera> since ELO was literally described by both Jeff Lynne and John Lennon as to pick up where The Beatles left off, and The Sons of the Beatles.
09:21:57 <Ampera> I love The Beatles, about equally with ELO.
09:22:04 <DHess_US> I thought that was the Monkeys.
09:22:18 <Ampera> The Monkees were the American Beatles.
09:22:46 <DHess_US> They did some individual songs I like but I wouldn't make a playlist with just Beatles.
09:23:04 <Ampera> ELO and The Beatles are of completely different styles musically, but when comparing them I find their songs appeal to the same sensibilities in terms of tune and enjoyment.
09:23:30 <Ampera> They both have songs I'm not fond of.

14:33:52 <Ampera> Yeah you wanna go into a PM or some sort of voice chat
14:34:24 <Ampera> Halcyon,
14:34:49 <Halcyon> Yeh, where is the best place to send you creds? PM ?
14:35:01 <Ampera> depends on how secure you want it, email is likely the best
14:35:14 <Halcyon> This is encrypted, so it should be OK
14:35:19 <Ampera> yeah but my IRC logs are not
14:35:26 <Halcyon> Damn you :P
14:35:41 <Ampera> and I can't guarantee that the credentials within them are going to be always safe.
14:35:47 <Halcyon> I'll just change them later
14:35:48 <Halcyon> It's fine

18:04:18 * Halcyon paws at T3sl4
18:04:35 <Ampera> hi Halcyon
18:04:42 <Halcyon> Hey Amps
18:04:44 <Halcyon> What's doing?
18:05:15 <Ampera> eh
18:05:16 <Ampera> eh
18:05:19 <Ampera> and another eh
18:05:19 <steve30> hi Halcyon
18:05:24 <Halcyon> Hey Steve :)
18:05:29 * Halcyon swats at Steve as well
18:06:11 <steve30> *purr*
18:07:17 <steve30> I want to go to the gym, but I'm reluctant to go out anywhere. But I have to go out as I have to go to the post office.
18:09:53 <Halcyon> Just get it over and done with :)
18:10:16 <Ampera> Halcyon, I wish I had that attitude.
18:11:09 <Halcyon> Me too, I find it way too easy to procrastinate, do other things and leave things until the last minute
18:11:20 <Halcyon> Although I work better under time pressure
18:11:36 <Ampera> If I did, I would have finally had the courage to have killed myself.
18:11:44 <Ampera> and I would be considerably happier for it
18:11:48 <Halcyon> That's awful
18:12:07 <Ampera> Halcyon, how so?
18:12:25 <Halcyon> Because running away from issues doesn't fix anything
18:12:26 <steve30> hi
18:12:49 <Halcyon> You have a lot to contribute to society. A lot of people can't say that
18:12:53 <Halcyon> They just "live"
18:15:34 <Ampera> Death is not running, it is skipping life's cutscenes.
18:16:04 <Halcyon> Unfortunately there is nothing after death
18:16:14 <Halcyon> Just lots of bacteria and insects
18:16:27 <Halcyon> And bloating
18:16:29 <T3sl4> hi
18:16:32 <Ampera> That is what we see
18:16:51 <Halcyon> I tend to believe in science as opposed to any sort of afterlife
18:17:11 <Halcyon> It's a comforting thought, unfortunately, at this stage, it's all make-believe
18:17:12 <Ampera> I believe that when I die, I enter into creative mode, and can do whatever I wish in life.
18:17:31 <Ampera> I can change myself and the world around me to solve all of my unsolvable problems.
18:17:49 <Halcyon> Like Minecraft?
18:18:06 <Ampera> An imperfect analogy, but also my own.
18:18:12 <Halcyon> I wish my house was like Minecraft, my front and rear yards would be finished by now
18:18:14 <Ampera> I like to think I become like Q
18:18:16 * steve30 afk
18:18:22 <Halcyon> Bye Steve :)
18:18:41 <Ampera> I can snap my fingers and be anyone, be anywhere, and do anything.
18:19:03 <Halcyon> I honestly don't know if I'd want to be anyone else
18:19:15 <Halcyon> I've never looked at a person and thought "I wish I was you"
18:19:21 <Ampera> I do it on a daily basis.
18:19:31 <Ampera> It's nearly impossible for me to not do it.
18:19:49 <Halcyon> :(
18:19:59 <Halcyon> I wish I could swap with you for a week to give you a break
18:22:01 <Ampera> It would solve none of my problems.
18:22:12 <Halcyon> But it would be like a holiday?
18:22:17 <Ampera> it depends on how deep the swap is, though, if you got all of my problems, then you'd fucking hate it just as much as I.
18:22:22 <Ampera> Not really.
18:22:30 <Ampera> If it is truly me that is in another body, then it has solved no problems.
18:22:53 <Ampera> My personal issue is that I find within myself a considerable discomfort with the way I am on an abstract and hard to quantify level.
18:23:15 <Ampera> My gender discomforts me, but I do not know what gender is, or why this one discomforts me.
18:25:23 * steve30 hugs T3sl4
18:27:16 <Halcyon> I know :(
18:27:19 * Halcyon hugs
18:27:24 <Ampera> ew gay
18:27:33 <Halcyon> It's only gay if you're another guy :P
18:27:47 <Ampera> I mean
18:27:52 <Halcyon> Also I hug my straight friends as well, so fuck you
18:27:52 <EEVBlog> Halcyon is interested, Halcyon!
18:27:59 <Ampera> YES
18:28:02 <Halcyon> Haha what the?
18:28:02 <T3sl4> a huggable steve30 appears!
18:28:03 <Ampera> YOU HIT THE MAGIC NUMBER
18:28:07 <Halcyon> \o/
18:28:07 * T3sl4 hugs
18:28:40 <Halcyon> Well you'll be please to know EEVBlog that I frequently pleasure myself :P
18:28:43 <Halcyon> *pleased
18:29:10 <steve30> :)
18:29:52 * T3sl4 offers steve30 some of his freshly prepared pasta and steamed cauliflower
18:30:32 <Ampera> Halcyon, 1 in 500 chance
18:30:32 <steve30> Pasta sounds nice. Don't care much for cauliflower though.
18:30:57 <Halcyon> How does it work? Like a RNG?
18:31:31 <Ampera> aye
18:31:39 <Ampera> when you say a specific set of words, it generates a number
18:31:39 <steve30> I need to make a doctors appointment.
18:31:51 <Ampera> and if it matches the right number then the payload activates
18:31:53 <Halcyon> What word(s) triggered that one?
18:31:56 <Ampera> that is the first time a 1/500 payload dropped
18:31:56 <T3sl4> good luck :P
18:31:58 <Halcyon> Obviously "fuck" was one
18:32:20 <Ampera> sex, fuck, suck, moist, penis, cock, schlong, member, wet, sperm, cum, jizz, intercourse, ejaculat, and porn
18:32:28 <Halcyon> Hahaha
18:32:38 <Ampera> If any of those are said, the payload is, Halcyon is interested, <NAME>
18:32:40 <Halcyon> I love that you included "moist"
18:32:49 <Halcyon> Hahaha !
18:32:52 <Halcyon> Thanks for that
18:32:54 <Halcyon> Why pick on me?
18:33:36 <Ampera> because I luv u
18:37:04 <Halcyon> :P
18:37:27 <Ampera> There are 5 1/500 payloads
18:37:31 <Ampera> and you just have to wait to hit the others
18:37:46 <Halcyon> Does it keep stats so you know when/how many times they are triggered?
18:37:52 <Halcyon> Or you just have to be there?
18:38:02 <Ampera> no it keeps no stats at all
18:38:05 <Ampera> it doesn't even log chat
18:38:06 <Halcyon> I see
18:38:59 <Halcyon> I just made a chicken schnitzel sammich
18:50:47 <Ampera> Halcyon, did you ever end up getting to contacting people?
18:51:35 <Halcyon> Not yet. Today was my first day back after the long weekend and I was putting out fires
18:51:41 <Halcyon> I shall tomorrow
18:51:41 <Ampera> fires?
18:52:06 <Halcyon> Just shit that needed to get done urgently
18:52:33 <Halcyon> As of Monday I'm working out of our headquarters for 3 months so I had some loose ends which needed tidying up
18:52:42 <Halcyon> (as in next Monday)
18:53:26 <Halcyon> And I'm only working a 2 day week this week
18:53:37 Quit: Bluenote ([email protected]) Quit: Leaving
18:56:02 <Ampera> Thanks Halcyon. No clue what you'll find, but at this point all I need is someone who knows a lot about trans issues and is willing to debate the crap out of me.
18:56:32 <Halcyon> No idea either, I haven't had a lot to do with your law enforcement. Most of my contacts work for your Federal agencies
18:56:55 <Ampera> Trust me you won't find someone here in law enforcement that deals with that.
18:57:01 <Ampera> It does not exist.
18:57:07 <Halcyon> I'm still going to ask the question
18:57:09 Quit: Bluenote ([email protected]) Quit: Leaving
18:57:17 <Halcyon> I'm sure my contact in the Secret Service won't be interested :P
18:57:20 <Ampera> In fact, the LGBT in the US actually hate the police
18:57:21 <Ampera> quite a lot
18:57:45 <Ampera> The entire left view the police as mindless brutes who don't want to do anything else but hurt minorities and abuse power
18:58:00 <Ampera> much of the left anyways, I'm generalizing too much
18:58:19 <Halcyon> Sure
18:58:29 <Halcyon> But it's still a contrast to here, one which I just don't understand
18:58:49 <Halcyon> You don't have to be a brute to be a good Police officer
18:59:36 <Halcyon> I mean sure, there is a job for those types. Normally it's kicking in doors and dealing with rioters. But they aren't paid to think, just like the Military, they are paid to follow orders.
19:00:55 <steve30> I booked in for tuesday afternoon
19:00:56 <Ampera> That's just how the cops are over here.
19:01:06 <Ampera> The people who deal with trans issues are way different, and way worse.
19:01:08 <Halcyon> *nod*
19:01:20 <Ampera> You know that person I was talking to you about, Arlene Lev?
19:01:28 <Ampera> The therapist my parents consulted when this first came to light?
19:01:50 <Halcyon> As I said, I think I've only ever met one of your Sergeant's, I forget where he was from now, nice guy though. He was here for our LGBTIQ Liaison officer's conference.
19:02:08 <Halcyon> Yeh I recall
19:02:43 <Ampera> One of mine?
19:02:50 <Ampera> What PD?
19:02:53 <Halcyon> An American cop
19:02:56 <Halcyon> I can't remember
19:03:04 <Ampera> Most American cops do not have jurisdiction where I live.
19:03:10 <Halcyon> I know
19:03:13 <Ampera> :P
19:03:21 <Halcyon> When I say "yours" I mean, from the USA somewhere
19:04:01 <Halcyon> Oh fuck yes! New Mike Jeavons :-D
19:04:18 <Ampera> I'm listening to the 10538 Overture
19:04:44 <Halcyon> I'm de/re-muxing Harry Potter and watching Youtube
19:05:11 <Ampera> mmm Harry Potter
19:05:15 <Ampera> I have all the movies
19:05:21 <Halcyon> I do now too :P
19:05:33 <Halcyon> They are just BD rips so I need to trim out all the garbage
19:05:36 <Ampera> pretty good, save for the author who is a massive cunt, and the retards who won't shut the fuck up about it.
19:09:30 <K> hello
19:12:34 <Ampera> I am having an incredibly interesting and engaging conversation with someone
19:12:41 <Halcyon> Oh ?
19:12:50 <Ampera> They're someone who is currently transitioning MtF, similar like I wish to, and I am getting some interesting information out of it.
19:13:08 <Halcyon> Nice, where are you chatting?
19:13:56 <Ampera> Steam
19:19:35 <Ampera> I feel my mind starting to break down
19:20:01 <Ampera> it's starting to get critical
19:20:09 <Ampera> shit
19:21:03 <Ampera> I'm not sure if my mind is beginning to return to normal, or if it's degrading further
19:21:34 <Ampera> My mind has not been operating right for so long, it's been silent, I haven't been able to deal with it, but I don't know what's happening to it right now
19:21:36 <Ampera> this is weird
19:23:35 <Halcyon> Well it's important to talk it out
19:24:10 <Ampera> I feel my mind beginning to rationalize the irrational, the very fabric of my doubts tearing apart to reveal a more perfect model of the world.
19:24:40 <Ampera> I feel strength, yet I do not know if it's one that will continue to drive me.
19:24:48 <Ampera> If it's enough to shove aside my impossible anxieties.
19:25:12 <Ampera> If I can truly reach a point of embracing the cavalier view of life I so wish to power me through.
19:25:54 <Ampera> I feel as if a wall within my mind is beginning to fall, yet I need one last swing to break it down.
19:26:13 <Ampera> My inner monologue has returned.
19:26:17 <Halcyon> :)
19:26:18 <Ampera> I don't know if it will remain.
19:26:24 <Ampera> but this is something I have not had in years.
19:27:35 <Halcyon> *hug*
19:45:50 <steve30> Apparently Dave has 17 oscilloscopes. Maybe he should do a giveaway :)
20:06:36 <K> he has 9 desks?
20:06:42 <K> then he is 1 short
20:14:52 <coppice> my inner monologue hates me
20:15:35 <Ampera> coppice, at least you have one.
20:15:37 <Ampera> Mine wavers
20:16:13 <coppice> When does an inner monologue transition to schizophrenia?
20:17:12 <Ampera> When they start screaming at you
20:41:46 <Halcyon> I'm making chicken and vegetable sausage rolls
20:44:04 <Stiff> nice!
20:47:22 <K> hello
20:48:10 <Halcyon> steve30,
20:48:19 <Halcyon> I'm thinking about getting this table for my entry hall: http://arts.theodorebruceauctions.com.au/custom_asp/fullcatalogue.asp?salelot=AS0601+++731+&refno=++153001&image=1
20:48:23 <Halcyon> What do you think?
20:49:30 <Stiff> wheres the other half of it
20:50:20 <K> bhh
20:50:46 <DHess_US> He is getting a good price. It is half off.
20:51:00 <Halcyon> You guys
20:51:13 <Stiff> hehe
20:51:58 <Halcyon> I want to put a nice chair next to it, maybe a Chesterfield so I don't have to sit on the floor or the stairs to put my shoes on
20:52:35 <K> to not break the pattern, chair should also be in hafl
20:52:45 <Halcyon> :P
20:52:59 <K> https://ecofriend.org/halfone-vertically-flipped-half-cut-chair-makes-for-a-hanger-shelf-3/
20:53:15 <K> it is eco! and probably gluten free!
20:53:24 <Stiff> perfect!
20:53:31 Quit: lexiyntax ([email protected]) Ping timeout: 121 seconds
20:53:31 <Halcyon> I don't need a big table in the hall
20:53:36 <Halcyon> It's just going to be for keys and such
20:53:44 <K> you need a biger hall then
20:53:51 <Halcyon> It's big enough
20:53:57 <Halcyon> It's like 2 metres x 4 metres
20:54:10 <Stiff> decent size hall
20:54:19 <Stiff> lash out and get a full table then :P
20:54:32 <Halcyon> I also deliberately don't want a large table/cabinet because it will just fill with crap
20:54:54 <Halcyon> Keys and wallets are enough

20:55:02 <K> yes. it is better to keep crap on the floor.
21:01:54 <DHess_US> <K> to not break the pattern, chair should also be in half
21:02:00 <DHess_US> Dude, that would be half-assed
21:03:02 <K> i get the impression that is the theme Halcyon is going for
21:17:14 <coppice> If only my inner monologue would keep reciting Shakespeare soliloquies to me, they'd be so much easier to learn

21:22:39 <Ampera> oh man it's great to walk upstairs and have like a 25% chance to see your dad sitting there crying his eyes out
21:22:50 <Ampera> lol
21:24:00 <K> why is your dad crying upstairs?
21:24:21 <Ampera> because my mom doesn't love him anymore
21:24:48 <K> it is sad
21:25:34 <DHess_US> Thanks for ruining Friday for me Ampera. You're a real pal.
21:25:48 <Ampera> this shit's been going on for ages now, I don't even know if it's a year or even longer, or less or what.
21:26:05 <Ampera> but he basically broke the fuck apart, and can't deal with life anymore
21:26:21 <Ampera> cause he has the emotional stability of a 21st Century Schizoid Man.
21:27:02 <Ampera> DHess_US, you can count on me to make my friends feel like total shit by sharing my depressing stories of my life as sad cries of help for the nobody who can help me with my impossible problems.
21:27:09 <Ampera> that's my specialty
21:27:46 <K> hm, i never found king crimson to be relatable to emotional instability
21:28:50 <Ampera> Schizophrenia is, K.
21:30:12 <K> it probably is
21:30:52 <Ampera> and it's the 21st century
21:30:55 <Ampera> and my dad is indeed male
21:31:16 <Ampera> add the three together (he doesn't actually have schizophrenia), and you get 21st Century Schizoid Man
21:33:13 <K> ok
21:33:41 <Ampera> ok
21:34:51 * Halcyon hugs Ampera
21:38:31 * Ampera hugs Halcyon, OwO
21:38:40 * Ampera notices bulge
21:39:29 <Halcyon> :P
21:39:50 <Ampera> how do Halcyon
21:40:11 <Halcyon> Doing OK, just looking at antiques
21:40:42 <Ampera> I don't have any pictures of my parents, but if I wanted to look at them they are still upstairs
21:40:49 <Ampera> although I think my mom might have left for work already
21:41:31 <Halcyon> :P
21:41:41 <Halcyon> Oh well, there is always my bulge

21:47:26 <steve30> Halcyon, table looks decent. I don't know what your hall looks like though so I've no idea whether it would fit in well.
21:47:44 <steve30> In other news, the council approved my council tax discount application, and I got £600 off.
22:02:16 <Halcyon> My hall is modern
22:02:27 <Halcyon> But I like older stuff, I think it would look alright
22:08:48 * steve30 has a celebratory coffee
22:10:18 <DHess_US> I like modern construction with modern materials with an emphasis on functionality over style.
22:11:47 <DHess_US> In other worse, I hate triglyphs.
22:11:56 <DHess_US> in other words
