00:12:21 <xDR1TeK> he got the frier for chinese xbox 1
00:13:36 <xDR1TeK> he can oversell this shit somewhere else, like the whole wide world
00:20:10 <ThunderSqueak> yeah, just boggles me that people are buying it, especially after seeing the specs
00:21:00 <Ampera> Fuck RTU
00:21:17 <Ampera> I have personal experience with him.
00:21:25 <Ampera> Not going to go into it, but for the record, fuck RTU.
00:21:46 <ThunderSqueak> ah, just showed up in my feed
00:23:02 <xDR1TeK> He is too straightforward
00:24:09 <xDR1TeK> Soulja Boy was a rapper?
00:24:17 <ThunderSqueak> apparently
00:24:45 <Ampera> he basically sold a console with a load of stolen ROMs
00:24:54 <Ampera> if you need a video on it, check out JonTron's
00:25:39 <xDR1TeK> brother that didn't know the difference between sno and knockoff

02:49:37 <ThunderSqueak> mrpackethead, https://www.youtube.com/watch?v=E6SplAMjfVo
02:51:55 <mrpackethead> just have a thread where someone is making a dick of themselves
02:52:07 <mrpackethead> best thing to do is to stop arguing.
02:52:30 <ThunderSqueak> ah
02:52:59 * ThunderSqueak is watching mst3k "Wizards of the lost kingdom II"
02:53:07 <ThunderSqueak> its so bad
02:57:20 <Ampera> The internet, and similar methods of common communication has been around for over 40 years, with arguments and shitting on about it henceforth, and you're still surprised about it?

03:08:57 <mrpackethead> Ampera. not suprized.
03:09:10 <Ampera> neither am I
03:09:43 <mrpackethead> i'm living life outside of the datasheet
03:09:54 <Ampera> the internet is the most efficient communication method humanity has ever invented, never before has it been easier to distribute your verbose and unhinged thoughts to the entire world.
03:10:23 <Ampera> It is perhaps a pitty that the human mind can be one of the most illogical, twisted, and often broken things within the natural world.
03:11:01 <mrpackethead> it keeps life interesting though
03:12:11 <Ampera> Negativity is the cheese to the french onion soup of life.
03:12:59 <Ampera> In other news I /really/ like DaVinci Resolve. It's some amazing software.
03:21:05 <IoTPanic> Whats special about it? I just read a big thing about it is online and offline use?

03:29:45 <mrpackethead> Ampera, yes, i agree. its everybit as a good as premeire
03:29:50 <mrpackethead> and its a LOT cheaper
03:29:56 <Ampera> Yes, free is a good price.
03:30:04 <Ampera> Also, Linux support, idk if premeire has that.
03:30:30 <mrpackethead> nice colour grading if you have a BD camera

04:05:56 <Ampera> I'm editing something for a small drama group I'm in. We do films every year, as well as a play (that's later), and I volunteered to edit it for them.
04:06:18 <Ampera> This is the first time I've ever edited anything substantial, but it's working amazingly well.

05:53:46 <rust_collector> back from putting 36 palletsn of thinkpads into the postal system. bye bye stinkpads!
06:22:09 <aram> rust_collector: I have T23, T41p, R60, 2xX61T, T400, T410, T430s, X240, X200, X220, T420s, T61, T510
06:22:33 <aram> though I don't use any anyome
06:22:41 <aram> s/anyome/anymore/
06:23:54 <rust_collector> I did look at some, a while ago, just for the pointing nub. iIrc, I was looking at the t40, t41, and t60
06:24:26 <rust_collector> but then I got a few hp elitebooks, so I didn't need one
06:27:43 <Halcyon> Morning all
06:28:32 <rust_collector> hello
06:33:15 <rust_collector> I am dismembering an old adjustable power brick. when I got the transformer out of it, there was not very much left
06:33:47 <IoTPanic> Hi Halcyon
06:33:53 <Halcyon> :)
06:34:21 <IoTPanic> I have wasted so much of my life waiting for windows to search its own filesystem -_-
06:34:28 <Halcyon> Hahaha indeed
06:34:36 <IoTPanic> Why did I buy a SSD? Why did I buy Windows?
06:34:44 <Halcyon> You *paid* for Windows?
06:34:49 <Halcyon> What is wrong with you?
06:34:52 <IoTPanic> Well, my work did
06:35:02 <Halcyon> That's alright then
06:35:19 <Halcyon> I mean I bought a copy of Windows 7, that was the one and only copy I've ever purchased
06:35:27 <IoTPanic> And the ATSAMD21G18A works much better on windows, but quite frankly Im caring less and less
06:35:54 <IoTPanic> I will just take off the bootloaders and use a programmer, fuck usb
06:36:53 Join: DogWomble ([email protected]) to #EEVblog
06:37:07 <Halcyon> Anyway I need to get ready for work *moan*
06:37:16 <IoTPanic> Alright
06:41:08 <rust_collector> so. this power brick I am messing with. it has a transformer, rectifier, some chip, blah blah. anyway, it gives me 63v ac on the output, and not 8 to 16v dc. So... I am guessing it probably is a diode? Does that sound right?
06:45:19 <rust_collector> I mean, how else would it give me ac out?

06:51:49 <DHess_US> rust_collector, how did you measure the output?
06:52:13 <DHess_US> 63 volts AC is suspiciously the value you get when you have a floating ground.
06:53:16 <rust_collector> well, I just stuck the dmm across the output leads.
06:54:21 <rust_collector> is 63vac a thing in the us, or did you translate it to european?
06:54:43 <DHess_US> That is for the US. I'm not sure what 240 VAC EU would produce.
06:54:53 <rust_collector> right.
06:55:33 <rust_collector> well, thanks anyway
06:55:57 <DHess_US> What happens is without a connection to ground and maybe neutral, 120 volt AC at hot divides with stray capaciance to produce 60 volts AC to ground.
06:56:16 Quit: DogWomble_ ([email protected]) Ping timeout: 121 seconds
06:57:14 <DHess_US> 63 volts AC isn't a very likely value from an off-line power supply under any common failure except a missing ground and/or neutral connection.
06:57:35 <rust_collector> That is also a thing here. I think I should add a ground wire to this thing, if I get it working

06:58:12 Mode: (by ChanOP) +o DogWomble
06:58:17 <DHess_US> Wait, is it connected to the wall with a 2 or 3 wire connection?
06:58:26 <rust_collector> 2 wires
06:59:08 <rust_collector> and it lives in a nice steel box
07:00:19 <DHess_US> I'd have some fun with my multimeter set to AC probing the outputs and inputs while the ground lead is held in my hand.
07:00:42 <DHess_US> Make sure your neutrals and grounds are actually connected.
07:00:49 <rust_collector> but for now, I am thinking I should do any "live" testing with my little bench supply, in place of the transformer.
07:01:25 <rust_collector> the neutral and ground in the wall?

07:10:01 <rust_collector> I mean, there is no ground on the device itself. just the live and neutral.

07:20:38 <rust_collector> at least I found a cross reference for the chip, so it seems to be a version of the lm723. that is something
07:20:41 <DHess_US> rust_collector, I would check all three of the wall socket connections but yes, only the two conencted to the device count.
07:21:16 <rust_collector> oh right.
07:21:24 <DHess_US> Ground and neutral should essentially be zero volts AC. Hot should be 240VAC. At least as far as I understand EU 240VAC.
07:22:17 <rust_collector> yeah, I think they are joined in the breaker box
07:22:24 <DHess_US> It isn't uncommon to find that hot and neutral are reversed or that neutral and/or ground are floating.

07:22:41 <DHess_US> Neutral and ground are joined at the distirbution panel.
07:23:40 <DHess_US> As far as I know, EU 240VAC is wired the same as US 120VAC. The difference is that the US has two different 120VAC phases from split phase 240VAC.
07:24:30 <rust_collector> I guess it would be very common to have the live and neutral reversed here, as there is no "key" on the plugs/sockets, so you have to guess which would end up where anyway
07:25:18 <DHess_US> Live and neutral reversed shouldn't be safety issue or affect operation unless you are using a really old device.
07:25:29 <DHess_US> Some old equipment has neutral connected to the chassis.
07:25:43 <DHess_US> Really old, like pre-WW2 old.
07:26:23 <DHess_US> https://en.wikipedia.org/wiki/All_American_Five
07:26:59 <rust_collector> well, there is just 21 parts in this thing. plus the transformer. I have to be able to figure this out
07:28:11 <DHess_US> If it is not a switching power supply, then I would measure the resistance across the input. If it is high, then the fusible link in the transformer is blown which is a common failure.
07:29:02 <rust_collector> good old iron transformer. I will look at that
07:31:18 <rust_collector> 34 ohms

07:33:17 Join: MrMobodies ([email protected]) to #EEVblog
07:38:27 <DHess_US> 34 ohms is probably good depending on the power level. What is the output voltage and current suppose to be?
07:39:41 <rust_collector> Well, after the regulator part, it is rated for 16V and 1.6A continous, and 2A max
07:41:31 <rust_collector> going by the transformer size and chunkiness, it is about the same as an old 4A car battery charger. Maybe not the most scientific measurement, but....

07:48:01 <DHess_US> Let's say 32 watts then. 240VAC at 32watts is 133mA across 34 ohms is 4.5 volts. That's a reasonable loss in the primary from resistance.
07:52:46 <rust_collector> plugged it in, and the bare transformer gives me 21.7V out
07:53:56 <rust_collector> I do believe the transformer is ok. just going by gut feeling, lol

08:05:31 <rust_collector> talking about crappy power supply things... How often do you really need less than say 2v?
08:08:31 Join: DogWomble ([email protected]) to #EEVblog
08:08:41 <rust_collector> I am just thinking about the 400 threads about diy power supplies. And going to 0v seems to be a very popular goal
08:09:32 <DHess_US> Most loads do not draw much power at such low voltages but low voltage operation is more common now.
08:10:51 <rust_collector> Yeah, I guess modern things might need it. I am probably pretty well stuck in 1978
08:12:09 Join: DogWomble_ ([email protected]) to #EEVblog
08:12:13 <DHess_US> If you are working with single cell circuits which need to be tested down to 0.9 volts then it would be a problem.
08:13:39 <rust_collector> good point
08:14:26 <DHess_US> The only power supply designs which should have trouble getting down to zero volts are those based on 3 terminal regulators.

08:14:52 * rust_collector makes note saying never make a single cell battery powered circuit
08:15:23 <DHess_US> Single cell circuits have been common going back decades for special applications.

08:18:19 <rust_collector> I was looking at this datasheet, and it does mention being adjustable from 2 to 37v output. I guess you could trick it into 0 to something.

08:19:59 <rust_collector> Oh well, first, get it working. It should be good enough for some uses. But if I could mess with it, and change the output a little bit, that could be a nice project for me, I guess

22:45:58 <Halcyon> Cool beans :)
22:46:38 <Ampera> If ye'r ever looking for a video editer for Linux, DaVinci Resolve is great, so long as no sound isn't an issue.
22:47:13 <Halcyon> Hah
22:47:27 <Halcyon> I've been using Premiere in Windows or OpenShot in Linux
22:47:34 <Halcyon> I don't do a lot of editing these days
22:47:41 <Halcyon> Got rid of most of my video gear long ago
22:49:41 <Ampera> well this is the first time I'm ever actually editing something
22:49:50 <Halcyon> OpenShot is basic (compared to Avid or Premiere/After Effects) but it does the job.
22:50:13 <Halcyon> Video production is fun. But an expensive hobby
22:50:24 <Ampera> DaVinci Resolve has an impressive set of features for costing nothing.
22:50:28 <Halcyon> I use to film promos for theatre productions
