40:38 <Ampera> I have 40 CAD in my wallet actually
40:59 <Ampera> just in case I'm being extorted by the canadian mafia
42:57 <k1tt1n> 40 CAD in coins, I hope.
43:41 <K> in cod
43:51 <k1tt1n> Even better!
43:54 <Ampera> nah, in monopoly money
43:59 <k1tt1n> Whelp
44:15 <Ampera> I can see through it at least
44:22 <Ampera> just so I know how hollow that asset is
44:49 <k1tt1n> Yeah they're hard to bleach.

06:31 <Nothing\> well i just got an idea for a programming exercise, not sure what language to do it in but i'll figure that out
07:16 <Nothing\> but I was thinking it would be nift to have a program to analyze simple RLC circuits when you just plug in numbers for R, L, C, F, V etc
07:53 <Nothing\> then it works out the reactances, prints them, and then prints the complex impedance
08:38 <Nothing\> though I was thinknig of making this in QB64 on my computer, or a version of basic called RFO Basic on my phone but it occurs to me that neither can natively handle complex numbers :/
08:55 <rust5> use excel?
08:56 <Nothing\> guess i'll have to learn to do it in python or c++
09:11 <Nothing\> rust5, excel's just beyond me tbh
09:26 <Nothing\> no word of hyperbole, my mother knows excel better than me
09:35 <rust5> ok, then you can do the next best thing, and use haskell
09:36 <Kuschelpony> i never dealt with complex numbers themself, just used a pair of real and imaginary components
09:39 <Nothing\> i actually have to ask HER for help with it when i'm using it
09:45 <Nothing\> or at least open office calc
10:00 <Nothing\> rust5, what's haskell? i've never heard of that.
10:08 <rust5> programming language
10:24 <Nothing\> hrm that's a new on eto me
10:33 <rust5> it is not exactly new
11:01 <Nothing\> I wrote a post in r/engineering asking them what a good engineering calculator was for windows and overwhelmingly most of the answers were either matlab or python
11:07 <rust5> https://www.haskell.org/
11:22 <Nothing\> which i didn't even think of python as a calculator, despite the calculator functions
11:25 <EEVBot> Unexpected error ((sqlite3.OperationalError) database is locked[SQL: SELECT nick_values.nick_id AS nick_values_nick_id, nick_values."key" AS nick_values_key, nick_values.value AS nick_values_value FROM nick_values, nicknames WHERE nicknames.nick_id = nick_values.nick_id AND nicknames.slug = ?

11:37 <Nothing\> but i couldn't see easily making a graph in python
11:39 <EEVBot> [url] Haskell Language | www.haskell.org
11:47 <rust5> heh
11:47 <Nothing\> thanks rust5, i'll have a gander
12:01 <Nothing\> and i've never used matlab in my life
12:18 <rust5> python is probably your best option, not that I can use it
12:46 <Nothing\> on my computer i usually use a combination of whatever purpose-made calculators i can find on omnicalc for the written stuff, and Desmos for graphing
13:01 <Nothing\> rust5, yeah i've been slowly learning it
13:39 <Nothing\> but i've also been learning this RFO basic language on android, which is actually pretty nifty. Lots of functionality for a BASIC language, and easily to pick up
14:12 <Nothing\> lets you access things like sensors, or edit HTML, or a lot of stuff most BASIC languages don't do
14:20 <rust5> I have figured out that I can not learn programming, so I am doing pretty good
14:31 <Nothing\> same, it's just not in my blood
14:54 <Nothing\> and even if i DID learn programming, I just haven't the patience for writing and debugging a complex program
15:03 <rust5> well, then stop wasting your time with programming
16:01 <Nothing\> also truth be told, I dunno if it's my meds, the drug abuse, my past abuse of my brain, age, my stroke, or all of the above, but my brain does not work as well as it used to. ANd not just in the normal getting older way.
16:27 <Nothing\> like i'll literally forget what i'm talking about in the middle of a sentence and have to ask my mum what I was talknig about.
16:52 <Nothing\> i have totaly blackouts for no good reason, sober or not
17:20 <Nothing\> like when i met my probation officer, I don't remember even going to the office.
17:30 <Nothing\> if not for my mum i would have thought i forgot
17:52 <rust5> that is because they gas you at the door, and remove your memory.
17:54 <Nothing\> i'm trying to tihnk of other examples, tehre are tons but it's hard when i'm put on the spot like this so to speak
18:38 <Nothing\> rust5, well i have no doubtt my one medication is at least making it worse since it is very well known to cause blackouts and memory problems. But usually only at really high doses
18:56 <Nothing\> and i mean i'm sure you've seen how disjointed my thought process can become sometimes
19:06 <rust5> they gas you in the waiting room, do their tests, glue your asshole shut, and put you outside in the park, to wake up
19:07 <Nothing\> it never used to be like that
19:14 <Nothing\> i used to be very articulate
20:02 <Nothing\> rust5, lol i always had the idea to genetically engineer puppies and kittens without an anus or urethra so they never produce any yucky pee or poop
20:44 <Nothing\> lol speaking of drugging patients unsuspectingly

21:34 <Nothing\> i was thinking, a perfect way to get somebody to stop being afraid to needles is with every needle you give them a small dose of morphine or fentanyl or something that feels super good
21:48 <Nothing\> that way they'll have more incentive to do it again when the time comes.
21:54 <rust5> the friend of a guy I used to chat with, got a kid thathad no exit hole, and part of the intestine things, when it was born. I am not sure what happened to that one, but it was not great
21:58 <Nothing\> heya kitt
22:00 <Nothing\> k1tt1n,
22:07 <Nothing\> lol i always do that with yoru name
22:12 <Nothing\> how ya doing bud?
22:26 <k1tt1n> They'll never know why they're so itchy either, right Nothing\?
22:54 <rust5> that is the ants
22:56 * k1tt1n just finished work
23:07 <k1tt1n> Adam and the Ants
23:25 <rust5> sounds british
23:32 <Nothing\> rust5, he was probably relegated to using some variety of colostomy bag, god help the poor guy.
23:51 <Nothing\> k1tt1n, heh i remember adam and the ants
23:53 <k1tt1n> Probably is. London underground punk scene?
24:00 <Nothing\> they were a band, were they not?
24:11 <Nothing\> k1tt1n, you were into the punk scene in the 80s?
24:14 <Nothing\> in london
24:30 <k1tt1n> I'm more into London After Midnight
24:41 <Nothing\> i mean, there was the london punk scene and the american punk scene, which were two completely different things as far as i'm concerned.
24:45 <rust5> oh, so not proper british. just londonic
24:46 * k1tt1n was shitting in grass in the 1980's
25:25 <Nothing\> k1tt1n, I came across a wiki article about the Punk ideology the other day and it said one of their key ideologies was mutual assistance. Would you agree with that?
25:59 <k1tt1n> Hmmmm
26:09 <Nothing\> =because from what I've seen re: anarchism and basically causing havok for no good reason, and disorganization, mutual aid does NOT seem like a punk ideology
26:29 <Nothing\> like, I dunno how accurate it is, but have you see SLC Punk?
26:32 <k1tt1n> Well, anarchy is rules without rulers.
26:40 <Nothing\> that's what I think when I think of the "classic" punk movement
26:53 <k1tt1n> So if you can get socialism without someone at the top, then maybe so.
26:58 <Nothing\> that is, before bands like AFI and Sum 41, and blink 182 etc
27:04 <k1tt1n> Yea
27:04 <Nothing\> soft-punk
27:39 <Nothing\> or even worse, groups like Face to Face or The Ataris where they claim they're punk, but all they do is bitch and pine for their lost teenage loves
27:51 <Nothing\> in their 30s
28:03 <k1tt1n> If each "mutual assistance" and "Punk ideology" fit with Freetown Christiania, then I suppose so.
28:07 <Nothing\> oh, no use for a name
29:09 <Nothing\> k1tt1n, the thing that got me was almost every one of the ideals the article listed were ideals shared by hippies, but at least in north american punk culture in the 80s, they HATED hippies.
29:28 <Nothing\> even though at their heart, they stood for the same things apparently
29:44 <k1tt1n> Because by the 80s, hippies turned into yuppies.
30:01 <k1tt1n> Gen X wanted their rebellion
30:08 <Nothing\> mainly anti-corporatism, non-conformity,fighting the laissez-faire, stuff like that
30:13 <k1tt1n> Yes
30:15 <k1tt1n> Gen X wanted their rebellion
30:20 <Nothing\> yup
30:22 <rust5> yes I did
30:25 <Nothing\> every gen does
30:35 <Nothing\> i'm not even sure what gen i'm part of
30:36 <k1tt1n> Good for you rust5 :^3
30:46 <Nothing\> according to current definitions, i'm a millenial
30:52 <rust5> I think I am the last or next to last year genX
30:57 <Nothing\> but i was born in 1985 so i'll be damned if i'm a millenial
31:03 * k1tt1n is technically Gen Y if you go by years
31:07 <Nothing\> i remember what life was like without the INTERNET
31:23 <Nothing\> at least without the internet in every home
31:41 <Nothing\> and when having a computer meant you were a nerd
31:53 <k1tt1n> But I grew up rural which pulled the calendar back into my Gen-X favour.
31:57 <rust5> I think I was 25, when we got internet
32:37 <Nothing\> k1tt1n, i grew up in canada within 100km of the american border so I'm basically americanized without any of the bullcrap that comes with living in america
32:44 <k1tt1n> 1980 is the year cutoff between Gen X and Millenial (Y)
33:01 <k1tt1n> Nothing\: you are for sure Millenial then. Good luck with that.
33:03 <rust5> I thought so. I am a -79
33:08 <Nothing\> rust5, eyeah i never got into computers until I was about 18 or so. EVen though I loved science since I could read.
33:28 <Nothing\> k1tt1n, I dunno I like to think of myself as gen Y
33:38 <rust5> yeh, people should stop confusing computers and science
33:39 <k1tt1n> Gen Y is Millenial
33:40 <Nothing\> late Gen Y, but Gen Y none the less
33:49 <Nothing\> k1tt1n, nah
33:55 <Nothing\> millenial comes after gen y
33:59 <k1tt1n> Nope
34:17 <Nothing\> millenial imo is like, born after 1990 or 95
34:24 <k1tt1n> Millenial is the alternate term to Gen Y
34:37 <k1tt1n> !wiki millenial
34:42 <rust5> there is no imo in that stuff. just look it up

35:08 <k1tt1n> Bye bye bot?
35:18 <Nothing\> Millennials, also known as Generation Y or Gen Y, are the demographic cohort following Generation X and preceding Generation Z. Researchers and popular media use the early 1980s as starting birth years and the mid-1990s to early 2000s as ending birth years, with the generation typically being defined as people born from 1981 to 1996.[1] Most millennials are the children of baby boomers and older Generation X;[2] mi
35:19 <Nothing\> parents of Generation Alpha
35:41 <Nothing\> i retract my incredulity, k1tt1n
35:41 <rust5> yes, bot has some issues today
36:11 <k1tt1n> rust5: Feels good perhaps?
36:14 <Nothing\> okay my kitty's meowing at me if i don't stare at her so i should go see what she wants
36:22 <Nothing\> take care guys. All the best. <3

12:55 <steve30> hi
13:11 <rust5> hellooo?

29:31 <Nothing\> oh hey maybe one of you can explain this weird effect i've noticed
30:54 <Nothing\> when I fill my tub full of water and then shine a laser pointer straight down into the water, there's a rather large and unmoving shadow surrounding the point of light in the bottom of the tub.
33:12 <rust5> the surface of the water acts like a mirror, so you see the back side of the laser light?
33:31 <rust5> antilaser
33:41 <rust5> yes, that is it

43:59 <Nothing\> hey, are the pi 4s still in short supply? or pis in general? I heard even 3s were hard to come by as of a month or two ago.
44:20 <rust5> nah, they are just really expensive
44:29 <Nothing\> Agripa3, that's a new interface to me. Also I like your name. I forget who agrippa was but i always liked the name.
45:15 <Nothing\> rust5, you want expensive. I was looking at (or trying to) the prices of R&S network analyzers. Damn things started at like $10
45:20 <Nothing\> $10k even
45:41 <Nothing\> and yet you can buy a nano-vna for like $50
45:43 <rust5> well, they are not exactly a pi

57:45 <Nothing\> heh
58:04 <Nothing\> hey, do any of you happen to know of any good molecule modeling software?
58:45 <Nothing\> I used to have this amazing suite like 15 years ago that was completely free, damn even remembering the name of it i can't even find evidence that it existed. Much less the suite itself
15:07 <Nothing\> you know what I'm wondering about my problems getting solder to stick to copper
15:43 <rust5> no
17:05 <Nothing\> i wonder if it's because i'm using a thicker gauge solder meant for plumbing. It's probably 2mm at least. Would certainly explain why I can't get it to melt properly when I heat the part and try to apply the solder. I always end up having to melt the solder directly on the soldering iron tip, and then it runs uselessleesly off of whatever i try to solder, but sticks fast to the tip of the iron.
17:23 <Nothing\> i tried going from a 30w to a 60w iron but to no avail.
17:51 <rust5> plumbing solder is not great for little things.
17:56 <Nothing\> rust5, yeah i really need to invest in an entry-level Hakko station. Been wanting to for some time.
18:08 <rust5> no, you need to get solder
18:10 <Nothing\> rust5, that's what I figured
18:42 <rust5> for little thruhole crap and small wires, even the usb powered 8w iron works
18:58 <Nothing\> actually I don't think it's plumbing. See my grandfather was an electrician and it was his solder, but he did more house-hold jobs and this was the 1970s.
19:10 <Nothing\> so, different (probably actually superior) formula
19:14 <rust5> did you try to add flux?
19:24 <Nothing\> not yet but that was an idea
19:32 <Nothing\> i assumed the rosin core would suffice
19:43 <rust5> if it is from the 70s, maybe it has dried out, or something?
19:58 <Nothing\> i think so because the rosin won't even mix evenly with the solder
20:08 <Nothing\> you get big globs of yellow rosin in your joints
20:19 <rust5> but, 2mm solder is probably not for little electronics
20:35 <Nothing\> yeah, not for a 0.2mm pin
21:20 <Nothing\> i dunno why i never thought of that until now but yeah, I'm totally gonna pick up some flux at least.
21:47 <Nothing\> now that I think about it, I HAVE used new solder. But it was from a kit and mostly tin based, so it was probably crap
22:37 <rust5> it is not supposed to mix with the solder, I think, so that is probably ok. but yes, get a little roll of what you need, it is not super expensive, it does last a long time
23:35 <Nothing\> that shall be done
23:48 <Nothing\> and i WILL watch life of Brian one day
23:53 <Nothing\> and The Dictator
23:58 <Nothing\> =P
24:03 <rust5> and, getting some flux is not a bad thing either,
24:05 <Nothing\> see? I haven't forgotten
24:12 <rust5> the dicktater
24:20 <Nothing\> rust5, better to have it and not need it than need it and not have it?
24:23 <Nothing\> flux
24:35 <rust5> oh, I see, you wrote it on a postit
24:42 <Nothing\> lol
24:48 <Nothing\> hey lemme ask you something
24:52 <rust5> yes, why not have some
25:00 <rust5> uhm, ok
25:24 <Nothing\> nm i forgot what it was
25:40 <Nothing\> what's a good program for modeling molecules?
25:46 <Nothing\> lol
26:05 <rust5> nah. it was the one after that
27:05 <rust5> So welcome to the machine
27:11 <rust5> thanks mrnoboobies
27:41 <Nothing\> man this shelf i got my mum for the rocks i bought her turned out pretty good
27:49 <rust5> ok
27:53 <Nothing\> even though it was like $30 for about $2 worth of acrylic
28:27 <rust5> the material is not what makes it cost, you have to cut it and stuff
28:59 <Nothing\> that can't cost much on a production line but i get what you're saying
29:08 <rust5> and ship it to china, so they can cut it, then send it to the us, so you can import it
29:47 <Nothing\> rust5, did i show you my haircut?
29:51 <rust5> nope
30:03 <rust5> did I show you my papercut?
31:35 <Nothing\> lol noo sounds unpleasant
31:43 <Nothing\> but yeah, before: https://i.ibb.co/Wsxc2H4/20230126-112609.jpg

32:06 <Nothing\> i swear i lost 5lbs
32:24 <rust5> yeah
33:03 <Nothing\> i feel bad about the beard but it was getting too unwieldy
33:04 <rust5> I was thinking about it the other...week... last time I got my hair cut, was before christmas -21
33:26 <Nothing\> i couldn't do up my jacket zipper without getting a huge chunk of beard stuck in it and torn out.
33:30 <rust5> hmm, it was the 20th of december
33:55 <Nothing\> that's okay, last time i took a "proper" shower was when trump was in office
34:19 <rust5> well, you know... when you zip your pants, most of us have learned to not have our appendix hanging out.
34:53 <rust5> you can do something similar with a beard, and not have it in your zipper
35:46 <rust5> not that I have that problem. I have an eternal 2 week looking beard, it more or less stops at around an inch
41:07 <rust5> I think I trimmed it down about a month ago... https://ibb.co/rM47d7k

35:48 <rust5> so, it is weekend, and time to fix the bot?
35:51 <electrohead> it seems like you enjoy that feature, you should totally add it to your bot :p

13:53 <Halcyon> Do you collect coins?
14:33 <k1tt1n> "Hoard" might be a better verb for it.
14:41 <Halcyon> Hahah
15:01 <Halcyon> Are they organised or just thrown into a container?
15:32 <k1tt1n> It's across a few locations.
16:18 <Halcyon> I have a small bag full of Aussie shrapnel that you're welcome to. Most people don't use cash here anymore and I haven't touched it for many years. I have no use for coins.
16:28 <k1tt1n> Different types too. Old constitutional, new sovereigns, corporate mints.
17:46 <k1tt1n> Aussie shrapnel?
17:59 <Halcyon> Coins
18:28 <Halcyon> I did a clean up of my junk drawer and there was a bunch of money in there
18:40 <k1tt1n> Ah lol
20:16 <Halcyon> Shrapnel is Aussie slang for coins. Because it's just shit that goes everywhere and no one knows what to do with.
20:17 <k1tt1n> I tend toward the 1960's-and-older kind of constitutional.
20:23 <Halcyon> Ah I see
20:53 <Halcyon> I sense Ampera is nearby as I have the sudden urge to poop
21:09 <k1tt1n> I'd imagine your shrapnel is all newer stuff - if not, you better investigate the value of it yourself.
21:38 <Halcyon> k1tt1n, yeh it's all modern stuff. I really don't care to be honest, I don't collect coins. I have enough stuff in my "collection" as it is without adding more.
22:01 <Halcyon> I have an entire room almost dedicated entirely to old computers and components.

46:28 <arch> i was trying to buy an automatic power mux, sot-23-8 form factor, but every single one of them from TI are out on digikey...
47:15 <arch> basically looking for a way to power my gizmo from two sources, with the USB being the primary, and lipo being the secondary power source
47:24 <arch> oc, i could use two OR-ed diodes
48:05 <arch> but i feel like the 0.5V drop is too much of a chunk of power/voltage loss
48:28 <arch> and this is optional too. so we'll see if i end up using it
49:37 <arch> this is for the DIY thermal camera project btw
50:21 <arch> the original uses a cascaded power method. the usb port output --> lipo charge circuit --> main switch --> boost conv --> thermal cam
50:36 <coppice> arch: where are you getting the image sensor from?
51:01 <arch> coppice, oh you know, shot down drones in Afghanistan... jk, i got the FLIR Lepton 3.5
51:23 <arch> and this is the project i am working on right now, it's a DIY thermal camera: https://www.diy-thermocam.net/

51:43 <coppice> arch: that's probably what you'd find in most shot down drones
52:00 <arch> i bet
52:21 <arch> well, it wouldn't be of much use. they artificially lock it down to i believe 5fps, just to prevent such usage
58:37 <arch> how safe is it to charge a single cell lipo battery with two LM317's? first one for CC, second one for CV? ive seen many such circuits online, but have never built one
14:40 <k1tt1n> Ooooo spicy pillow

29:02 <steve30> Just had a youtube advert suggesting that i move to Western australia
31:00 <DogWomble> why move over there? the eastern states are far better
38:13 <arch> just need a quick sanity check. anyone see any issues with this power mux stage? micro usb (5V) should always be the primary, as the lipo voltage rail (4.2V) will always be lesser. https://i.imgur.com/QpsnlIX.png
38:45 <arch> sorry for the messy schematic btw
41:49 <arch> oh and the benefit of this is, you can set a much lower charge current for the lipo charger
42:01 <arch> and let the main power be handled simultaneously for the FLIR
42:31 <arch> things will get rather toasty at 1A current when the battery is discharged fully, as the lipo charge IC is linear

18:22 <MrMobodies> if I join the main and remote channels
18:37 <MrMobodies> in a bipolar configuration
19:16 <MrMobodies> would that still be 80w @ 4 ohms?
27:36 <MrMobodies> looking at the datasheet I think not
27:57 <MrMobodies> I thought it was a 4 channel it is not
28:21 <MrMobodies> it is 2 channels (left and right) with a relay that switch between main and remote

06:21 <MrMobodies> what I don't understand is, at 8ohms why does the Technics perform 10w better (80w to 90w) whereas the Peavey will drop 45w less (150w to 105w)

44:21 <newbie> Hey all
46:05 <newbie> I am travelling overseas where the voltage is 220v (my home country is 110v). I had a question about the difference between voltage converters (light weight and works above a certain load ) vs step down transformers
47:11 <newbie> I tried using a voltage converter with an air pump for an air mattress and after a short time the motor stopped working and smelled burnt. Is it that the voltage converter provides a chopped ac signal and ac motors do not like it?
49:47 <Kuschelpony> hello newbie
50:01 <newbie> Hi Kuschelpony
50:12 <Kuschelpony> your cnclusion is exactly right
50:55 <Kuschelpony> the "coverters" are a very dagerous thing that works by chopping up the voltage shape, that works only with specific loads (pure heaters)
51:05 <newbie> I figured voltage converter would be ok with resistive loads and also that a motor would be a simple non complicated electric circuit and it would also work with the converter which was not the cae
51:20 <Kuschelpony> every other load, espicaly everything modern including electronics is very likely to be misworking or gettng damaged
51:32 <Kuschelpony> mmmh even motors can be an issue
52:01 <Kuschelpony> its ok with series wound "universal" motors, but NOT with rectifiers & DC Motors
52:04 <newbie> Ok.. I also brought with me a 110v sewing machine so I will look for a step down transformer
52:19 <Kuschelpony> yes thats the only safe option
52:47 <newbie> Perhaps my Coleman air pump that takes ac input had some rectrification along with a DC motor then
53:05 <newbie> Do you think that voltage converter would be ok with an ac motor?
54:07 <newbie> Curious for the sake of understanding
55:26 <Kuschelpony> real AC motors might somewhat overheat and run with more vibration, but are at least not directly in danger
55:59 <Kuschelpony> you can identify the motor tyes by their noises
56:13 <Kuschelpony> AC motors do have mostly a low hum
56:50 <Kuschelpony> DC & Rectifier motors do have a kind of howl, but the note does change very little with airflow
56:55 <newbie> Interesting.. perhaps later on I will open up that air pump to see if some thermal fuse had blown.. there was a lot of sparks coming out the side of it and it worked for about 5 min of use
57:12 <Kuschelpony> "universal" Motors have a howl that changes very much with airflow, typical vacuum cleaner
57:26 <newbie> I didn't know that you can identify by the noise.. thank you
57:29 <Kuschelpony> ok Sparks, then it was likely a DC plus Rectifier motor
57:37 <Kuschelpony> sure, im happy to share knowledge
58:12 <Kuschelpony> the problem with this kind of motor is that their current is a kind of balance between the outer voltage and their inner back EMF voltage
58:41 <Kuschelpony> so if the outer voltage is spiky, it causes an even more spiky current, that can far exceed the steady state current
59:07 <newbie> Much appreciated ! I should have checked here first before trying.. when I was at home I tried to simulate the overseas environment by stepping up 110v to 220v and then using my voltage converter to change to 110v but I only tested the air pump for a few seconds...
01:30 <Kuschelpony> understood
02:05 <Kuschelpony> im living in Germany, 230V land, and in my previous job i got lots of these devices for repair...
04:10 Join: Skaface82 ([email protected]) to #EEVblog
07:33 <newbie> Where people in Germany used voltage converters to use 110v devices that ended up failing?
09:27 <Kuschelpony> that was around the US bases in the 90s where they brought their devices from home
10:30 <Kuschelpony> a few houses actually had a central transformer generating 2*115V split phase, but normally there was nothing and people just brought their adapters and converters and tried what happens
10:47 <newbie> Ahh I see. They should put a large warning on these travel voltage converter in my opinion
10:59 <Kuschelpony> welll, or just plugged right into 230V and BANG
11:06 <Kuschelpony> right so
11:06 <newbie> Lol
11:40 <Kuschelpony> unfortunately people are just getting overloaded from even trying to follow and understand how complex things are todays
12:17 <Kuschelpony> as a more recent example, which traditional dimmer works with which compact fluorescent or LED bulb
13:41 <newbie> By the way.. many adapters such as laptop or cell phone chargers have a wide input voltage.. are these also working in the same principle as voltage converters at the input to the switching power supply circuit?
14:45 <Kuschelpony> half-yes
16:02 <Kuschelpony> their working principle (its called flyback converter) is to chop up the mains voltage with a high frequency, to charge a kind of magnetic storage in the converter inductor
17:11 <Kuschelpony> so its their very principle that they can just follow a wide range of voltages by simply regulating the internal pulse width to get just the right amount of power
17:46 <Kuschelpony> if you want to learn more you might look up the classic UC3842 chip
18:59 <newbie> Ok. Thank you. Is there any advantage in plugging in such an adapter that accepts a wide voltage range to step down transformer? Would there be less stress on components?
20:35 <Kuschelpony> no, works equally well
21:54 <newbie> Oh ok. Silly me thought there might be some benefit and plugged in my 65w rated adapter into my 50w step down transformer and after time it looks like it died ...smells burnt
22:07 <Kuschelpony> mmmh :(
22:15 <Kuschelpony> im sorry for you having all these experiences
22:17 <newbie> Oh well lesson learned
23:14 <newbie> Well luckily a relative had an air blower that I could use.. and that step down transformer .. I don't think it cost much so it's a learning experience
24:19 <newbie> I am more worried about the vomiting , neasuea and diahrea I am experiencing :(
24:34 <Kuschelpony> ooops sorry
28:31 <newbie> I am out. Thank you again Kuschelpony. Much appreciated
30:39 <Kuschelpony> have a nice time
