00:00:50 <jackbrown> hi there
00:00:52 <jackbrown> anyone ?
00:02:42 <Ampera> no
00:02:43 <Ampera> I'm not here
00:34:54 <jackbrown> which one should I buy? There are too many versions https://www.eevblog.com/forum/testgear/$20-lcr-esr-transistor-checker-project/
00:34:54 <EEVBlog> If you keep saying that, I'm gonna hold you upside down and shake you until all the electrons fall out, jackbrown!
00:49:31 <K> buy any, they are all the same
00:49:41 <K> and it is only 20 monetary units
01:38:48 <Ampera> now why did the bot say that...
01:39:00 <Ampera> you obviously hit a payload, but I'm not sure which
01:40:18 <steve30> Maybe he just likes jackbrown's electrons
01:42:20 <K> which one should I buy?

02:23:03 <jackbrown> hey I have a cordless Iron 6W that works with 3 1.5V AA batteries, do you guys think I can add a micro USB female port so I can use with any USB charger without batteries ?
02:24:21 <K> can any usb charger supply at least 1.2A?
02:24:51 <AndrevS> I doubt it
02:24:52 <jackbrown> K: maybe they are only 500mAh
02:25:13 <K> mAh
02:25:15 <K> ?
02:25:19 <jackbrown> K: I should use then a specific USB charger that is able to supply more Amperes
02:25:28 <jackbrown> mA
02:25:29 <jackbrown> sorry
02:25:30 <AndrevS> mA, not mAh.
02:25:36 <jackbrown> yes I Know
02:25:37 <K> um,i would get some wall wart with barrel plug
02:26:01 <jackbrown> if I use a Fast charge USB that suplly at least 1Amps I could use it ?
02:26:27 <jackbrown> quick charge
02:26:34 <K> huh, not sure about usb c and power negotiation there
02:27:24 <jackbrown> K: ? sorry ?
02:27:57 <K> isn't "fast charge" usb c related?
02:28:59 <AndrevS> There are some other pre-usb-c protocols out there.
02:29:41 <jackbrown> K: I have one of them but you can plug any USB, you're saying that it works just if I use an USB Type C ?
02:29:42 <K> are those just "to hell with spec" type of thing?
02:30:15 <jackbrown> K: maybe you are right, I was thinking about microUSB port because it's cheap and very easy to find, but it seems that won't work
02:30:37 <K> jackbrown, no, i am not quite shure what you mean by "Fast charge", and assumed it is that new usb-c feature
02:31:11 <K> usb-c is more tricky than regular, afaik
02:31:32 <K> why not wallwart with a barrel jack?
02:31:47 <K> micro usb isn't very sturdy
02:31:49 <jackbrown> K: yes I mean Quick Charge, and I have a smartphone Type C that supports that, but the charger has a common USB port on its side so I tought that it could work either with a USB -- MicroUSB cable, but now I think that probably it's just when you plug a TypeC cable and a smartphone that supports that
02:32:13 <coppice> USB-C must have been developed as a joke
02:32:25 <jackbrown> K: USB Type C has 24 contacts I don't think it will be easy to install such a female port on my soldering iron and anyway the effort doesn't worth the result
02:34:13 <jackbrown> K: anyway they charging system must be related to some feedback into the smartphone that is able to demand more Amperes I suppose
02:34:34 <K> yes, that is what i was getting at
02:34:59 <jackbrown> K: a barrel jack is another option but I have to find then a charger specific, I tought about micro USB because is very widespread and you'll find a charger like that everywhere but 0.5Amps are not enough
02:35:38 <AndrevS> Quick Charge is a specification by Qualcomm. Since Quick Charge 4.0, it's USB-PD compatible.
02:35:49 <jackbrown> yep
02:36:09 <jackbrown> it's not just a plug that you insert and give you those volts and those amperes, it's a bit more complicated
02:36:10 <K> https://www.ebay.com/itm/6V-DC-0-5A-1A-2A-Power-Supply-Adapter-110-220-6-V-Volt-6Volt-Wall-500ma-1000ma/122358417488
02:36:16 <AndrevS> This protocol is only relevant if you wish to select a different voltage then 5.0 volts
02:37:00 <jackbrown> K: thanks I already have a adjustable charger I can use that one
02:37:46 <jackbrown> Changing topic since I'm practicing soldering does anyone has a nice and maybe useful kit DIY to practice ? I did some SMD soldering but I'm sick, I was thinking about that tester I linked before but I'm still confused
02:41:11 <K> those tester kits look good for practice imho

02:42:45 <jackbrown> K: but I'd like to get the ones that is better, has the latest firmware and it's more functional since there's an EEVBLOG forum thread I was asking here
02:42:56 <jackbrown> https://www.eevblog.com/forum/testgear/$20-lcr-esr-transistor-checker-project/
02:42:56 <EEVBlog> If you keep saying that, I'm gonna hold you upside down and shake you until all the electrons fall out, jackbrown!
02:43:03 <jackbrown> EEVBlog: it's your blog!!
02:45:07 <K> huh, i dont really know about more functionality. I bought an assembled one few years ago and it does everything I expect
02:47:59 <jackbrown> K: ok thanks!

03:45:15 <T3sl41> in context, the blood + bandage combination had me going for a moment
03:45:32 <T3sl41> since the rather plain outline they use for the bandage resembles a tampon

04:53:43 <Agripa> jackbrown, the USB charging standards use enumeration in one form or another unless you limit yourself to 100 milliamps. USB-C also includes DRM to lock out foreign chargers if the manufacturer wants.
04:54:42 <jackbrown> Thanks!
04:54:57 <T3sl4> although most ports do 500mA without negotiation
04:57:40 <coppice> that's the default mode from which they begin negotiating
04:58:30 <Agripa> T3sl4, and many are simply not regulated at all but the standard requires negotiation for more than 100 milliamps whether that is done or not.
04:58:49 <T3sl4> yup
04:59:32 <Agripa> Some systems just include a polyfuse which won't save a connector but will prevent a fire ... sometimes.
05:09:41 <jackbrown> Which kind and size of SMD LED this DIY clock mounts ? https://www.youtube.com/watch?v=3C9p4ng2z7E
05:15:29 <coppice> That's a bizarre product. No wonder its so expensive
05:30:05 <jackbrown> ?
05:30:17 <jackbrown> coppice: expensive ? Bizarre ^?
05:32:13 <coppice> $10 for a kit you'd buy as an assembled unit sensibly constructed for $2 or $3 is bizarre
05:39:03 <jackbrown> coppice: if you buy red color it's just 3€ shipped https://www.aliexpress.com/item/DIY-Large-Screen-6-Digit-Two-Color-LED-Clock-Kit-Touch-Control-w-Temp-Date-Week/32949488720.html?
05:40:49 <jackbrown> coppice: do you have another kit to suggest?
05:48:36 <T3sl4> hmmm, my scope seems to be unusually noisy on one channel
05:51:52 <T3sl4> seems to be current noise on hi-Z inputs...
05:53:37 <T3sl4> DC offset is also all over the place... something's fucky in the AFE i guess
06:05:03 <steve30> interference from nearby teslacoils perhaps?
06:06:44 * T3sl4 frowns
06:06:50 <T3sl4> it wasn't doing this before tho :/
06:08:15 * steve30 pets T3sl4's oscilloscope
07:07:52 * rust_collector fondles T3sl4's probe
07:08:19 * T3sl4 zaps rust_collector
07:08:43 * rust_collector feels joy
07:10:40 <Ampera> Good news everyone! I've taught the toaster to feel love.
07:11:03 <T3sl4> hah
07:11:13 <T3sl4> although i forget that scene :/
07:11:25 <Ampera> it's where the professor teaches a toaster to feel love.
07:13:01 <T3sl4> ಠ_ಠ
07:26:49 <jackbrown> any good Soldering-Paste-Flux on Aliexpress ?
07:32:55 <Ampera> soldering paste flux?
07:33:05 <Ampera> which one
07:33:19 <Ampera> unless there is specific flux for soldering paste, then ignore my inquiry
07:41:05 <mrpackethead> jackbrown, what are you trying to do
07:41:38 <mrpackethead> morning coppice, T3sl4 and Ampera
07:41:45 <T3sl4> 'lo
07:41:51 <jackbrown> mrpackethead: I would like to mount this kit https://www.aliexpress.com/item/DIY-Large-Screen-6-Digit-Two-Color-LED-Clock-Kit-Touch-Control-w-Temp-Date-Week/32949488720.html
07:42:01 <Ampera> hi mrpackethead, you still on holiday?
07:42:04 <jackbrown> I never used soldering paste flux
07:42:44 <jackbrown> I always used this method, put flux on pad, then using a C tip tin all the pad with the thinnest amount of solder, then I used the Hot Air gun to attach the smd components
07:42:57 <T3sl4> paste flux is bae
07:43:03 <mrpackethead> oh you need to assemble it from the parts
07:43:10 <jackbrown> T3sl4: bad?
07:43:23 <T3sl4> love
07:43:35 <jackbrown> I bought this too https://www.aliexpress.com/item/Multifunctional-Tester-GM328-Transistor-Tester-Diode-Capacitance-ESR-Voltage-Frequency-Meter-PWM-Signal-Generator/32951690966.html?spm=a2g0s.9042311.0.0.641c4c4dEkhvxf
07:43:43 <jackbrown> T3sl4: what?
07:44:04 <T3sl4> https://www.urbandictionary.com/define.php?term=Bae
07:44:13 <mrpackethead> so, since its surface mount parts, put some solder paste on the pads. put your parts on, then you can heat them with the hot air
07:44:26 <mrpackethead> there is already flux in the paste
07:45:14 <jackbrown> mrpackethead: you are not suggesting me to buy solder paste flux ? I never used before
07:45:43 <T3sl4> solder paste is solder + flux
07:45:47 <T3sl4> paste flux is flux
07:46:18 <T3sl4> "solder paste flux" isn't something you will see, aside from "paste flux" that is for "soldering"
07:46:19 <Ampera> T3sl4, sing us song you're the piano man
07:46:38 <T3sl4> the Ampera smells like a beer
07:46:55 <Ampera> alright well
07:47:02 <mrpackethead> jackbrown, solder paste is a mix of tiny balls of solder, and flux
07:47:07 * Ampera starts T3sl4's firew
07:47:35 <jackbrown> mrpackethead: I know what is it, but I never used. It's just that I don't want to waste money buying some bad quality, I was looking for a small amount for a reasonable price.
07:48:12 <jackbrown> mrpackethead: plus I never bought because I heard that since it's mixed with flux, once the flux is evaporated it turn into shit and you have to add more flux maybe to fix it
07:48:37 <mrpackethead> jackbrown, yes solder paste has a limited life time.
07:50:06 <mrpackethead> https://www.chipquik.com/store/product_info.php?products_id=470011
07:50:09 <jackbrown> mrpackethead: I heard that, since I don't solder that much I never bought it
07:50:24 <T3sl4> jackbrown, what are you doing?
07:50:57 <jackbrown> T3sl4: I will assemble some practicing kit I bought over aliexpress, 2 clocks and a tester
07:51:09 <T3sl4> ok, so hand soldering is fine
07:51:23 <jackbrown> T3sl4: https://www.aliexpress.com/item/DIY-Large-Screen-6-Digit-Two-Color-LED-Clock-Kit-Touch-Control-w-Temp-Date-Week/32949488720.html?spm=a2g0s.9042311.0.0.50404c4dWR7E8C
07:51:32 <Ampera> I wonder if San Marino will ever win a eurovision song contest
07:51:38 <jackbrown> https://www.aliexpress.com/item/Multifunctional-Tester-GM328-Transistor-Tester-Diode-Capacitance-ESR-Voltage-Frequency-Meter-PWM-Signal-Generator/32951690966.html?spm=a2g0s.9042311.0.0.50404c4dWR7E8C
07:51:45 <Ampera> I'd really love them to, because it would be the most hilarious thing to ever happen to the event
07:52:25 <T3sl4> yeah, that looks fine to hand solder, no need for paste
07:52:33 <T3sl4> flux, probably
07:53:18 <Ampera> there doesn't even look like there's anything surface mount you have to solder there
07:54:56 <jackbrown> Ampera: https://www.aliexpress.com/item/DIY-Large-Screen-6-Digit-Two-Color-LED-Clock-Kit-Touch-Control-w-Temp-Date-Week/32949488720.html?spm=a2g0s.9042311.0.0.50404c4dWR7E8C
07:55:00 <jackbrown> Ampera: most is SMD
07:55:15 <Ampera> oh, thought he meant the other one

11:38:14 <Halcyon> Morning all!
11:38:15 <Halcyon> :)
12:09:59 <Ampera> hi Halcyon
12:10:10 <Ampera> was just thinking about you
12:14:40 <Halcyon> Oh yeh?
12:15:06 <Halcyon> What are you wearing? ;-)
12:16:38 <Ampera> a shirt
12:16:56 <Ampera> but more that I need to get the rest of the stuff for your care package
12:42:48 <Agripa> https://apina.biz/169170.webm?mode=sfw
12:44:28 <Ampera> 1 question: why
12:45:34 <Agripa> The power of derp compelled them.
12:47:41 <Ampera> that question wasn't for them, it was for you
12:57:31 Join: Egsample ([email protected]) to #EEVblog
13:05:27 <Agripa> The power of derp compelled me also.
13:06:02 <Ampera> I've seen worse shit, but some dude getting his thumbs machetted off might not sit well with some people, just as a warning.
13:07:22 <Egsample> So tech heads is 5G good or bad?
13:07:56 <Ampera> Apparently Huawei was behind much of Australia's 5G infrastructure, which is being delayed or canceled
13:08:09 <Ampera> As for if it's good or not, that depends on who is selling it.
13:08:27 <Ampera> It it makes prices cheaper, data caps higher, and speeds faster, than I'd say sure
13:08:39 <Ampera> if it doesn't do any of those things, not so much
13:08:46 <Egsample> is all this health concern real?
13:09:56 <Egsample> Microwaving the planet or is this just internet bullshit?
13:09:56 <Ampera> Not in the slightest.
13:10:34 <Ampera> Low and high frequency EM bombards us on a daily basis, and RF EM of the type cellphone towers use has nowhere near the energy needed to cause significant damage.
13:11:28 <T3sl4> RF is basically heating risk only. There are no credible implications of e.g. cancer risk.
13:11:29 <Ampera> You'd probably get buzzed harder standing next to an AM/FM transmitter, maybe a VHF/UHF TV tower
13:12:02 <Ampera> Well so is light, and that gets piped down at us in considerably stronger intensities than lower frequency stuff
13:12:26 <Ampera> well light can cause cancer if you get enough of it, but again, intensity.
13:12:38 <T3sl4> well, not visible light, at least not as far as i know
13:12:43 <Ampera> also frequency affects how the energy is propogated, which is different.
13:12:48 <T3sl4> as you go past blue, things change considerably
13:12:54 <Ampera> aye
13:12:54 <T3sl4> but below there, yeah, nothing credible
13:13:07 <Agripa> Penetration depth depends on frequency. You don't get RF burns on your skin.
13:13:40 <T3sl4> the delicious sear in my broiler says that's not true :>
13:13:55 <Ampera> that's not RF
13:14:00 <Agripa> I've gotten RF burns a couple times. They are not fun.
13:14:21 <Ampera> That must be some pretty high power RF
13:14:47 <Ampera> but if you bombard enough energy worth of anything at anything, you'll get a reaction
13:14:49 <Agripa> Or well focused. Stick you finger inside of a 2 meter helical resonator and 1 watt will hurt you fast.
13:15:37 <Agripa> On the other hand, 5 watts into a 6 meter dipole will only heat your hand because of low coupling.
13:15:41 <Agripa> err, 50 watts
13:15:52 <T3sl4> unless you touch the tip
13:16:05 <T3sl4> depending on Q, of course
13:16:07 <Agripa> You have to touch it just right or you just detune the whole thing.
13:16:16 <T3sl4> yup
13:17:53 <Agripa> As far as cellular radiation, the AM envelope might affect some chemical reactions but the researchers usually dont' distinguish modulation types so it is not clear.
13:18:55 <Agripa> If there is something going on, then it is not very significant compared to other hazards.

22:42:18 <Danol> Hello
22:42:51 <Danol> I'd like to ask about this weird behaviour of my surge protector. I've bought one with the Master/Slave functionality.
22:43:19 <Danol> When it is turned off, I can see status LEDs of the devices connected to the slave ports shortly blinking from time to time
22:43:30 <Danol> As if there was some sort of short circuit

23:58:00 <Agripa> Danol, could be leakage through the TRIAC's snubber circuit.
23:58:38 <Danol> The surge protector is brand new, should I return it?
23:58:49 <Danol> Or can I do anything about it?
