13:08 <Ampera> Halcyon,
13:20 <DogWomble> lightbulb
13:37 <Ampera> heavybulb
13:59 <DogWomble> super dooper pooper scooper
14:01 <Halcyon> Copy your PM. We can work something out
14:16 <Ampera> I do not expect plans to be even made in any real capacity until 2020
14:20 <Halcyon> Also on the other thing, I have emailed a few people, waiting on replies, obviously the time zone is an issue :P
14:32 <Halcyon> I probably won't get a chance to check my work email until Monday
14:49 <Ampera> I'm still willing to talk to people, but at this moment I've shifted priorities to understanding the technical aspect of transitioning.
15:02 <Halcyon> Fair enough
15:05 <Ampera> At this point my primary need is an up-to-date, no bias technical authority to tell me what I am getting into
15:28 <Ampera> but I am always willing to talk to people, I just don't think that anybody would provide me with anything useful, and that it would be mostly indoctrination, not therapy.
15:40 <Ampera> That's just how the disorder is treated.
16:28 <Halcyon> I can only do so much from here
16:36 <Halcyon> I'll pass on what I find out, the rest is up to you
16:51 <Ampera> however after an extensive talk with the person I told you about (which ended up in me cutting all communications with them), I have a better grasp on my situation at hand, and better confirmation of my concerns about the community at large.
17:52 <Ampera> She basically proved every single issue I had with things like trans spaces and the trans community being more like a cult than a community, while simultaneously disagreeing with all of it
18:10 <Ampera> (by all of it I mean, all of what I thought about it)
18:36 <Ampera> all she really did was try to guilt me into transitioning, and kinda minimized my concerns about it, treating them as wrong and stupid.
19:57 <EEVBlog> New EEVBlog Tweet: He's not wrong. NSFW The Death Of Australian Comedy https://t.co/DgMDawEQeZ
20:26 <Ampera> I believe I've come to a timeframe regarding my initial steps of transition, once I have all of the technical details I need. I believe by 2020 I will have several months of HRT performed.
20:47 <Ampera> with the start frame likely going to end up being this summer, at some point.
22:09 <Halcyon> Obviously be sure that this is what you want to do
22:28 <Ampera> That was the strange thing about the person I was talking to
22:44 <Ampera> she seemed outwardly convinced, after barely any talking, that I already knew what I wanted to do, just that I was holding back for no reason
22:49 <Ampera> and continually tried to convince me otherwise
24:14 <Ampera> Anyways I need to get her out of my head, and know that no matter how crazy other people with my problem might be, they are other people, and I don't have to let them get to me
24:16 <Ampera> knock on wood
26:09 <Ampera> Yeah, again sorry for going off I do it way too much
26:14 <Ampera> nobody wants to hear about my bullshit :P
26:21 <Halcyon> Don't apologise
26:23 <Halcyon> I do
26:36 <Ampera> don't refuse my apology, that only makes me madder
26:41 <Halcyon> Good :P
26:41 <Ampera> :3
26:44 <Halcyon> *prods*
26:45 <Ampera> >:3
27:06 <Halcyon> I do have to go start dinner though
27:31 <Ampera> It's 5:30 in the morning here
27:35 <Ampera> so I have to start going to bed soon
27:45 <Halcyon> Yeh maybe think about it :P
27:52 <Ampera> think about what
28:15 <Halcyon> Going to bed
28:39 <Ampera> well thank you Halcyon
28:42 <Ampera> you've confused me now
28:49 <Halcyon> Might talk to in the morning (your afternoon/evening)
29:22 <Ampera> what
29:38 <Halcyon> I have to go make dinner, you were going to bed?
29:45 <Ampera> yeah
29:56 <Halcyon> So you may not be here when I get back
29:58 <Ampera> I was just about to before you pinged me
30:05 <Ampera> I might not, no clue
30:06 <Halcyon> Sorry
30:19 <Ampera> Don't apologize
30:20 <Ampera> that also makes me mad
30:21 <Ampera> very mad
30:28 <Halcyon> Fuck you, accept my apology :P
31:19 <Ampera> fuck you? fuck me?
31:21 <Ampera> fuck everyone
31:29 <Halcyon> Ew, no thanks
31:32 <Ampera> we live in a fuck or get fucked world, you and I, and we have to learn to like it
31:37 <Halcyon> Well... maybe T3sl4
31:47 <Ampera> yeah because he's gay enough for you, unlike me
31:51 <Halcyon> I've chosen my position :P
31:55 <Ampera> I'm an evil evil bisexual
32:15 <Halcyon> Eh, could be worse... you would be an angry lesbian
32:20 <Halcyon> *could
32:31 <Ampera> whenever I think of lesbianism I for whatever reason think of bread
32:39 <Halcyon> Bread?
32:41 <Ampera> bread
32:41 <Halcyon> Like a loaf?
32:45 <Ampera> load of bread
32:51 <Halcyon> Random
33:03 <Halcyon> I think bread tastes and smells a lot nicer though?
33:07 <Halcyon> Just a guess
33:14 <Ampera> how many lesbians have you smelled and tasted though?
33:17 <Halcyon> None
33:21 <Ampera> so how can you tell
33:24 <Halcyon> Which why I'm just guessing
33:34 <Halcyon> Well... bread is appealing. Lady parts are not.
34:14 <Halcyon> Anyway, I'm going to go before the conversation turns to yeast :P
34:29 <Ampera> ciao

55:04 <Ampera> I win!
58:39 <Halcyon> \o/
59:19 <Ampera> Hi Halcyon
59:23 <Ampera> I didn't end up sleeping because fuck that shit
01:36 Join: Nothing\ ([email protected]) to #EEVblog
01:46 <Nothing\> ugh it's toooooo damn early
02:22 <Halcyon> Fair enough
02:37 <DHess_US> It's always too damn early somewhere.
02:46 <Ampera> Hi Nothing\
02:51 <Nothing\> and i dunno why, but my idea for switchable capacitors on a 555 with a multiplexer didn't work out, it worked fine in simulation but in real life the best i could get was a few cycles, then it'd die
02:54 <Nothing\> hey Ampera how goes it?
03:06 <Ampera> aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa
03:12 <Nothing\> it wasn't a total loss though, i figured out a terrific method for multiplexing that beats what i've been doing
03:17 <DHess_US> That's certainly feasible to do Nothing.
04:15 <DHess_US> I can think of at least 4 ways. No, 5 ways.
04:24 <Nothing\> i tried 2 different types of multiplexing, initially i'd make a switch tree like what you get in a DAC, but i figured out if i use a priority decoder to address transmission gates it's a LOT simpler
04:51 <Ampera> man all I wanna do is suck peepee
04:54 <DHess_US> Transmission gates is one way although they tend to have pretty high series resistance.
04:59 <Ampera> is that so hard
05:03 <Halcyon> Since when Ampera?
05:11 <Nothing\> DHess_US: yeah i had at least 2 ideas although the one involving the switching tree, i realized later the analog switch IC's VCC wasn't connected, i accidentally connected v+ to the neighboring pin
05:13 <Ampera> I got your attention didn't I :P
05:21 <Halcyon> You always have my attention
05:22 <Nothing\> but you know how ICs turn zombie when you forget to connect the power
05:28 <Ampera> Halcyon, I always want to suck peepee
05:31 <Nothing\> so i didn't notice until later when i was taking it apart
05:37 <Halcyon> Fair enough
06:01 <DHess_US> Often CMOS ICs can be powered by their inputs if the supply is disconnected but still decoupled.
06:23 <Nothing\> DHess_US: see i was trying to figure out why they used transmission gates addressed by priority decoders in these multiplexers instead of using a switching tree with inverters like i always did
06:54 <Nothing\> DHess_US: yeah i figured that out pretty early on in my journey through EE, luckily enough i saw 2 videos on youtube about it a couple of weeks beforehand so i knew exactly what was happening
07:27 <Nothing\> it's funny cuz dave made a video where he was utterly amazed by it like he'd never seen it, meanwhile i was barely a few months into EE and i was familiar with it thanks to youtube, what an age we live in
07:58 <DHess_US> Circuits have sometimes gone into prodoction and nobody noticed.
08:27 <Nothing\> actually you know, i'm not sure that regular BJT 555s have protection diodes
09:45 <DHess_US> They sort of do. They use a junction isolated NPN process so all of the collectors are tied to the substrate through a reverse biased diode. If you try to pull a collector below ground, the substrate diode will be foreward biased.
10:00 <Nothing\> early on in my journey i found i was able to measure a pretty accurate resistance across the power pins, or between VCC and control or ground and control, since control taps off the 3 resistors in the divider network, i got 18k across the power pins, 12k going one way across control, and 6k going the other way
10:22 <Nothing\> somebody was trying to tell me all i was measuring was the protection diodes
10:32 <DHess_US> Some ICs have a separate substrate connection but usually it is just tied to the pin which will be the most negative.
10:37 <Nothing\> but those are pretty specific numbers to be protection diodes
10:53 <Nothing\> ah i see
11:02 <Nothing\> i only know what a substrate is from mosfets, heh
11:34 <Ampera> I had some beef soba
11:37 <DHess_US> That is why positive and negative regulators have differetn pinouts.
11:38 <Nothing\> i was interested in IC fab back in the day but there are just sooo many topics in EE to tackle, i wound up gravitating towards the more practical ones
11:48 <Nothing\> Ampera: what's soba? isn't that an energy drink or something
12:04 <Ampera> very plain, just some beef bouillon and kinda cheap soba
12:05 <Nothing\> DHess_US: do they? i have 7805s and 7905s and never noticed, though i've not used the 7905s yet
12:08 <DHess_US> The center pin or tab must be connected to the most negative voltage because it is always the substrate.
12:08 <Ampera> Nothing\, buckwheat noodles
12:15 <Nothing\> actually lately i've been really interested in lmc7660s
12:52 <Nothing\> they seemed kinda complicated and scary compared to voltage regulators but once i figured out the capacitor switching and designed a simulation of the same thing, it was more fascinating than scary
12:57 <Nothing\> Ampera: oh yeah i remember now
13:12 <DHess_US> 7805 center pin is common. 7905 center pin is input.
13:38 <Nothing\> Ampera: huh i remember back in the 90's i always saw infomercials with this japanese dude advertising this thing called the sobakawa pillow, which was a pillow filled with buckwheat
13:42 <Nothing\> now the name makes sense
14:19 <DHess_US> 7660s have their own substrate problems. For instance they won't start into a positive load.
14:23 <Nothing\> DHess_US: i've been trying to figure out if i can make a dual rail supply with a 7805 and 7905 but i couldn't figure out how it could be done considering i'd have to use v+ and v- as common connections on each chip
14:41 <Ampera> Nothing\, I remember the 90's
14:46 <Ampera> it was very dark and staticy
14:51 <Ampera> nothing happened until 2002
14:52 <Nothing\> DHess_US: yeah i'm not sure if it's related to the substrate but i also read you have to use a diode on the output above a certain voltage
15:06 <DHess_US> Nothing\, it requires a + and - supply to do that.
15:16 <DHess_US> So +, -, and common.
15:35 <Nothing\> ah
15:51 <DHess_US> It *is* possible to do it without common but there are some restrictions on the output currents then.
16:21 <Nothing\> i figured there was more to it than just using a 7905 and 7805 together cuz the app notes for the 7660 made a big deal about being able to generate a negative rail from one chip, like making a negative rail damn near requires its own PCB or something
16:41 <Nothing\> Ampera: hell i barely remember the 90's myself
16:45 <Ampera> if you keep going north you will start going south
16:53 <Nothing\> i have a lot of conflicting memories
16:56 <Ampera> until you start going north again
17:58 <Nothing\> like i always remembered when i was 5 or 6, watching the x-files with my brother in the first house i grew up with, and he tried to scare me by telling me it was based on a true story, i even remember he tried to freak me out about this creepy guy (who was real) who hung around the park and sat on the swings behind our house and he actually had a hook for a hand lol
18:09 <Nothing\> he'd just sit there mumbling at himself or screaming at no one in particular
18:30 <Nothing\> but when i looked into it, the x-files didn't start until after i moved out of that house
18:43 <Ampera> that's pretty good
18:56 <Nothing\> Ampera: the universe is shaped exactly like the earth if you go straight along you end up exactly where you were
19:16 <Nothing\> damn if i remember which song that was from, something by modest mouse
19:24 <Nothing\> 3rd planet i think
19:46 <Nothing\> i used to love modest mouse
20:59 <Nothing\> DHess_US: i've been playing around with the idea of "steering diodes" in a 555 as well, to steer the current to one resistor when it's charging, and another while it's discharging, so i can tailor the duty cycle much easier and get a 50/50 no problem
21:28 <Ampera> Nothing\, perhaps time is the same way
21:57 <Nothing\> Ampera: if it is' it might as well be an eternity before things reset considering how long heat death would take
22:43 <Nothing\> but it's been found the universe's expansion is actually speeding up, so it seems likely we'll just keep expanding into nothingness as entropy stops anything new happening
24:36 <Nothing\> DHess_US: i feel like i should retackle this 555 capacitor switching thing today, i would really like to make a sort of keyboard from it, where i have 8 buttons that switch to a different capacitor
25:01 <Nothing\> or better yet, make it into an atari punk console, and THEN use it like a keyboard
25:26 <EEVBlog> New EEVBlog Tweet: Noooooooooooooooooooo! Faulty Mr Fusion https://t.co/tUEJqAtaJs
29:01 <Ampera> aww, poor DeLorean
30:13 <Nothing\> any time i see the word analog i can't help but see the word "anal og"
30:38 <Nothing\> i could see analog.com being a porn site for gangstas
31:31 <Nothing\> Ampera: heh you ever see that episode where somebody sent dave a replica of the time circuits display and he went and fried it almost immediately
32:15 <Ampera> Nothing\, this might seem insane, but I don't really watch the eevblog
32:17 <Nothing\> damn i keep getting a whiff of the rotting cabbage in my garbage and it smells like juicy fruit, it's making me crave it
32:32 <Ampera> I watch it on occasion, and /should/ watch it more, but I don't
32:36 <Nothing\> Ampera: nah i can understand that, i watch it sort of sporadically myself, i haven't watched at all since he moved
32:38 <Ampera> and instead focus more on his community than his content
32:49 <Nothing\> it's hard to keep my attention on his videos just cuz they're so long
32:57 <Nothing\> and they can be kind of dry at times
33:24 <Ampera> aye
33:32 <Ampera> Sometimes I like dry content, but sometimes I just can't do stuff
33:36 <Ampera> but I watch it when it's interesting to me
33:42 <Nothing\> yeah you've gotta be in the mood for it
33:44 <Ampera> and I used to watch it way more than I do now
33:49 <Nothing\> same
33:57 <Nothing\> i dunno if it's gone down in quality or what
34:06 <Nothing\> i can't put my finger on why i don't watch it as much anymore
34:25 <Ampera> who knows
34:36 <Nothing\> i guess because his videos now seem less about actual hands on electronics, like he does interviews or videos about his lab, or maybe one about letting the magic smoke out of something
34:46 <Ampera> My mom's called in sick from work today
34:54 <Nothing\> aww, make her some soup
35:00 <Ampera> and is hopefully learning a hard and good lesson as to why you shouldn't drink your face off
35:04 <Nothing\> oh lol
35:04 <Ampera> with 4 tall cans of beer
35:14 <Nothing\> that's equivalent to about 6 or 7 regular beers
35:23 <Ampera> all in a row
35:26 <Ampera> one after the other
35:26 <Nothing\> ugh i can't drink anymore
35:53 <Nothing\> i used to drink a lot but for some reason i lost my head for it, the hangovers just far outweigh the "fun" of being drunk
36:04 <Ampera> I don't know if I'll ever drink. I personally think beer is disgusting, but am sort of attracted to the concept of spirits and cocktails.
36:07 <Nothing\> not that i like being drunk, it's way too sloppy and feels like being poisoned, which i suppose it is
36:18 <Nothing\> yeah i won't lie, i think beer tastes gross as hell
36:25 <Ampera> It smells like vomit
36:30 <Nothing\> i dunno how anyone could enjoy it
36:34 <Ampera> which might have to do more with the sort of vomit I might have smelled, but still
36:43 <Nothing\> i dunno what it smells like but it sure doesn't smell like anything you should be putting in your body
37:07 <Nothing\> and considering i used to drink cough syrup for fun as a teenager, that says a lot
37:08 <Ampera> I mostly drink milk
37:23 <Nothing\> strawberry nesquick is the shit
37:35 <Nothing\> i could quaff a liter of that stuff in like 15 seconds
37:37 <Ampera> My mom started doing that a bit, she was sick for ages, and has a very very stubborn cough
37:53 <Ampera> so she basically kept buying nyquil, until I told her it's addictive
37:56 <Ampera> and she probably shouldn't
38:17 <Nothing\> actually nyquil isn't addictive, but it's chock full of tylenol, so it'll kill your liver
38:29 <Ampera> Anything can be addictive, Nothing\
38:45 <Ampera> it might not be chemically addictive, but neither really is alcohol
38:57 <Nothing\> not physically addictive anyways, the worst thing in it is the dextromethorphan which itself isn't physically addictive at therapeutic doses, but i've experienced physical withdrawal from it myself but i was using insane amounts
39:02 <Nothing\> like 50x a normal dose
39:25 <Ampera> Personally there is only one thing that does anything in NyQuil
39:29 <Nothing\> guess i sorta contradicted myself
39:29 <Ampera> and that's the antihistamine
39:48 <Nothing\> Ampera: yup, at therapeutic doses, dextromethorphan proves little more effective than a placebo
40:08 <Ampera> Tylenol does absolutely nothing for me whatsoever, and that long word drug thing, indeed does nothing.
40:38 <Ampera> Guaifenesin is something that I've found helps quite a lot, especially in liquid form.
40:39 <Nothing\> even when it is effective it's not necessarily in your best interests to suppress a cough, for instance with bronchitis you need to be able to bring up the phlegm and stuff to clear the pathogens from your lungs, otherwise they'll all just sit there and your immune system has more work to do
41:18 <Ampera> So when I can't take an antihistamine because of sleep issues, I take a liquid form of Mucinex DM
41:26 <Nothing\> Ampera: guaifenesin is to loosen up phlegm by adding water to it, it is a very useful compound but i don't understand why they combine it, a drug meant to loosen phlegm so you can cough it up, with a drug that inhibits coughs
41:47 <Nothing\> why can't you take an antihistamine?
41:57 <Ampera> because it has a good chance of putting me to sleep
42:26 <Nothing\> if you take dramamine, it's the exact same thing as benedryl but with a xanthine compound added to combat the drowsiness
42:49 <Ampera> but that's the only reason I care about the antihistamine
42:51 <Ampera> it knocks me the fuck out
43:05 <Nothing\> they have 2 different names for the drug for some reason, benedryl is diphenhydramine and dramamine is dimenhydrinate but dimenhydrinate is literally just diphenhydramine with some xanthine
43:09 <Ampera> and even when I wake up I will feel properly numb for like an hour
43:21 <Ampera> Doxylamine succinate is what is in NyQuil, which is what I use.
43:35 <Nothing\> ah yeah that will cause drowsiness
43:42 <Ampera> Benedryl doesn't work so well for me. It can have the similar effect as Doxylamine succinate, but it doesn't have the same chance.
43:47 <Nothing\> you should really look for another source of it without the tylenol
43:51 <Ampera> Sometimes it will work brilliantly, and sometimes it won't work at all.
44:05 <Nothing\> yeah me neither, i don't have allergies but i take benedryl for nausea and it never seems to work well
44:18 <Ampera> I should probably look for a unitary source of it, because I will, almost always, prefer Aspirin if I need something
44:28 <Ampera> and I will sometimes combine it with Tylenol, to which it sometimes works better with it
44:51 <Ampera> I take it if I just want to fall asleep, which isn't an amazing idea to do, but eh
44:54 <Ampera> who cares
45:09 <Nothing\> actually one thing tylenol works well for for me is headaches, but that's it
45:22 <Ampera> Tylenol doesn't do headaches for me much.
45:40 <Ampera> They will end up going away at the same rate
45:46 <Nothing\> honestly it's probably fine to take it for sleep once in a while, maybe once or twice a month, but any more than that and you risk becoming psychologically dependent on it to sleep
45:51 <Ampera> Aspirin, however, does help me, although it will sometimes leave a strange taste in my mouth.
46:12 <Nothing\> you know peptobismal has drugs related to aspirin in it
46:21 <Ampera> I've never used pepto
46:22 <Nothing\> actually the mint flavoring is even related to aspirin
46:35 <Ampera> Nothing\, did you know that I often smoke my food using Willow wood
46:37 <Nothing\> oil of wintergreen is a salicylate, which i didn't realize has the same effects as aspirin
46:50 <Nothing\> that's interesting, it never bothered your stomach?
46:53 <Ampera> the bark to which contains amounts of salicylic acid
47:14 <Nothing\> salicylic acid is supposed to be pretty irritating to the GI tract, hence the need to acetylate it
47:16 <Ampera> Considering I am setting fire to a small handful of wood, with rarely any bark, and have no direct contact with those elements, no.
47:41 <Ampera> Yeah but the amounts within food smoked with willow wood are so miniscule, if even present, that it has never effected me, and I've used it considerably.
47:45 <Nothing\> right on, at those temperatures you're probably just gonna pyrolize any salicylates into carbon anyways
48:02 <Ampera> It's a really really nice wood to smoke with, it can make meat taste like chocolate covered coffee beans
48:02 <Nothing\> heh that reminds me of this bath bomb i got from the dispensary the other day
48:17 <Nothing\> they were handing out these cannabis bath bombs there for 4/20
48:19 <Ampera> dispensary? They make weed bath bombs?
48:24 <Nothing\> apparently lol
48:42 <Nothing\> but i'm thinking, a couple hundred milligrams of thc dissolved into 250 liters of water isn't gonna do jack
48:49 <Nothing\> especially considering THC isn't even water soluble lol
48:49 <Ampera> reminds me of the people years ago who would trip out on something called bath salts, take their clothes off, run into the streets, and start eating people
48:51 <Ampera> or some shit
49:10 <K> or shit
49:15 <Ampera> or shit
49:20 <Nothing\> yeah they weren't really bath salts, that was just a front because they were legally grey so you could legally sell them so long as it wasn't for human consumption, so they called them bath salts
49:44 <Nothing\> i saw one site selling synthetic cannabinoids as fertilizer for bonzai trees once lol
49:57 <Ampera> I remember a really really strange compound that I was given by my grandmother, and they were really similar to pop rocks
50:11 <Ampera> but I was insisted to that they were for putting in a bathtub, for whatever reason
50:18 <Ampera> despite them literally tasting sweet and like pop rocks
50:22 <Nothing\> but yeah bath salts were stimulants, so after binging for a day or so they user would experience literal psychosis
50:51 <Nothing\> that's weird, bath salts are usually magnesium... something, i can't recall the name but it's a salt so it should taste salty
51:00 <Ampera> No it wasn't bath salts
51:07 <Ampera> but it was some strange thing that fizzed in the tub
51:10 <Ampera> like something for kids
51:15 <Nothing\> although come to think of it i'm not sure exactly what makes a salty taste, whether it's the actual chloride ion or if any old ion would work
51:20 <Ampera> but I swear they were literally pop rocks, because I would eat them
51:29 <Nothing\> oh okay i sort of know what you mean
51:36 <Ampera> Nothing\, doesn't potassium chloride taste salty?
51:49 <Ampera> isn't that what they use for NoSalt?
51:53 <Nothing\> it's supposed to but apparently it doesn't taste very good
51:59 <Nothing\> but yeah they use it as a salt substitute
52:16 <Nothing\> they also used to use sodium bromide as a sedative and anti-seizure medication
52:26 <Nothing\> which they now use as a pool chemical for something
52:36 <Ampera> Now I understand that the median lethal dose for caesium chloride is not much different than sodium/potassium chloride
52:39 <Nothing\> i've been really into chemistry lately
52:54 <Ampera> so I wonder if A. that it would be reasonably safe to eat in small quantities, B. what caesium chloride would taste like
53:09 <Nothing\> Ampera: extractions and ire has a video where he tries various salts to compare them
53:27 <Nothing\> he had caesium chloride, rubidium chloride, potassium chloride and ammonium chloride
53:36 <Ampera> video
53:41 <Nothing\> lemme find it
53:47 <Nothing\> it's a good channel actually, you'd like it
54:18 <Nothing\> https://www.youtube.com/watch?v=RJh9yTIBY48
54:45 <Nothing\> i never liked taste test videos cuz they just don't do the taste justice
54:57 <Nothing\> english lacks the language to properly describe smells and tastes
55:37 <Nothing\> but yeah, that's the guy's second channel which is more demonstration type stuff, his primary channel is extractions and ire which is focused more on documenting chemical syntheses
55:55 <Nothing\> explosions and fire is more just playing around with what he synthesized
57:28 <Ampera> interesting
57:33 <Nothing\> man i've been playnig a lot of gta v lately, but my big problem with the game is it's got this huge map with absolutely gorgeous scenery, but there's hardly any incentive to explore it, you can look for those note scraps or ufo parts, but those things are so hard to find that after 20 hours i only got 3 note scraps
57:55 <Ampera> Nothing\, I've never played GTA, I'm a bigger fan of Saints Row
58:01 <Nothing\> just cause 2 is nice cuz there's a lot of upgrades and such to look for
58:02 <Ampera> (3, 4, and gat)
58:08 <Nothing\> i never played saint's row
58:21 <Nothing\> i'm finding i don't seem to enjoy a lot of ps3 games
58:21 <Ampera> and they tend to have really nice maps, with lots of stuff to do, and at least /some/ excuse to go around doing stuff
58:26 <Ampera> even if it's mostly cosmetic or minigames.
58:34 <Ampera> I play it on the PC, like a good boy
58:50 <Ampera> by the way, how did/is that whole court thing working out
58:57 <Ampera> haven't talked about that in ages, is that still going on?
59:00 <Nothing\> ah man, it's still being delayed
59:07 <Ampera> that's the courts for you
59:19 <Nothing\> it's been almost a year since i was charged, i loathe to think what would have happened if i didn't make bail
59:23 <Nothing\> i'd still be in jail

59:33 <Nothing\> it's scary
59:37 <Nothing\> hey T3sl4
59:44 <Ampera> still can't say what you were charged with?
00:15 <Nothing\> nah but i will say it relates to drugs
00:24 <Ampera> hm
00:29 <Ampera> you're a canoodlian, right?
00:35 <Nothing\> yup
00:42 <Ampera> interesting
00:54 <Nothing\> at least i've stopped worrying about it
01:05 <Ampera> being a snow mexican?
01:05 <Nothing\> since moving out of my old place i've gotten away from the terrible memories of when they raided me
01:13 <Ampera> I wouldn't stop worrying about living in canada
01:19 <Ampera> or being canadian
01:20 Quit: T3sl4 ([email protected]) Ping timeout: 121 seconds
01:37 <Nothing\> was sleeping soundly in my bed, nude btw, at 8am, friggin cops burst into my apartment and within a couple of minutes i'm in the back of a car
01:42 <Nothing\> it's scary how fast it happened
01:56 <Nothing\> scary how your life can get so badly fucked up so quickly and without warning
02:25 <Ampera> sorry I brought it up
02:38 <Nothing\> it's okay, i actually have to call my lawyer today anyways so it's good you did
02:45 <Nothing\> i keep forgetting
06:29 <Ampera> anyways I think I'm gonna do a sleepy now
06:31 <Ampera> morning
06:43 <Nothing\> i should do that soon myself, i only got 3 hours of sleep
06:49 <Nothing\> have a good one, man
14:38 <Nothing\> hrm well i think i figured out why my multiplexed 555 didn't work, it looks like these multiplexers only pass current one way, even though they're analog
15:04 <Nothing\> i had a feeling i'd need to provide a negative voltage cuz there's VDD, VSS and VEE
15:37 <Nothing\> that's weird, i didn't have to do that with the analog switches
24:27 <Nothing\> well what the hell, the pins on these 7660s are too small to fit in my breadboard
24:34 <Nothing\> i had this same problem with my 7555s
25:05 <Nothing\> yeah, and just like the 7555s, some have longer pins than others for some reason
25:13 <T3sl41> because salvaged
25:51 <Nothing\> yeah i just noticed the pins on these have already been bent into place, where normally they'd be splayed out too far to fit in a breadboard until you bend them slightly
26:23 <Nothing\> when i got them they were covered in some sort of thick, sticky liquid too, no clue what it was
31:14 <Nothing\> fuuuuu i just noticed there are still packages i ordered in january that haven't got here, and about 15 i ordered in february that haven't arrived yet
31:24 <Nothing\> what ar ethe odds that many packages went missing
31:43 <T3sl41> better odds they're on a boat somewhere over the pacific
31:47 <T3sl41> ...or stuck in customs
32:11 <Nothing\> probably customs, it sounds from the vague tracking info that it was at least sent to canada
32:25 <K> chips from china again?
32:32 <Nothing\> yup
32:39 <K> deary me
32:42 <Nothing\> i also got a drinking bird that came yesterday lol
32:53 <Nothing\> i had to get one after seeing that episode of the simpsons
34:47 * T3sl41 pours Nothing\ a Tab
35:22 <Nothing\> lol i meant the one with homer's brother, but yeah i guess they had one in that episode too
36:41 <Nothing\> huh these lmc7660s have a lot more uses than just generating a negative rail, can even use em as a DC voltage doubler
40:54 <Nothing\> hey i've been trying to figure this out, what's the difference between using a straight PWM signal to attenuate voltage and using a buck converter? do you just get more current from a buck converter?
42:09 <T3sl41> PWM only works when the load is resistive, or inductive with diodes
42:45 <T3sl41> a [filtered] buck converter just goes DC to DC, and usually also has controls so it doesn't go assplodey when abused
43:26 <T3sl41> there's PWM inside such a thing, but that's really beside the point of what the control is doing
45:22 <Nothing\> yeah, to pump the inductor
46:31 <Nothing\> heh one of the first circuits i ever explored was boost converters, i remember being so confused because ever tutorial showed it as just a plain switch for the inductor and would even just call it a switch, though some of them went in depth enough to actually explain that it's a FET
47:04 <Nothing\> and not a single thing i've read on them ever once mentioned using feedback to stabilize the output voltage across different loads
47:41 <T3sl41> not on a tutorial level, no

50:34 <Nothing\> neat, that's a real simple design for a voltage doubler they've got here for the 7660
50:58 <Nothing\> well what the hell, it WAS twice the voltage, now it just collapsed back down to less than vcc
51:09 <Nothing\> boourns
51:38 <T3sl41> mind the voltage limit on that thing
51:54 <Nothing\> no it turned out i turned the power source off and forgot lol
52:00 <Nothing\> i was just measuring the caps discharging
52:21 <Nothing\> i'm just using a 9v anyways so i should be fine
52:46 <Nothing\> this thing takes a while to wind down, wow
