00:22:07 <Lemon> watcher you just discovered how manufacturers dont give a shit :>
00:28:53 <watcher> that means that the ddm only can take 600 volt and you can measure 750 or 1000 volt. than you will blow up you ddm before you even reach the measuring limit :)
00:29:16 <watcher> than i will never buy one.
00:29:44 <Lemon> well usually they can take much more than their limits
00:29:53 <Lemon> but you need to take care with cheap dmms, regardless of the specs
00:30:01 <Lemon> at how they are fused, protected, insulated etc
00:30:18 <Lemon> id say just avoid them if you can, besides a few that will be ffeatured there and here
00:33:35 <watcher> most products can take a couple % more than what the manufacturer say. and i was not intend to buy now beacuse the ddm has not all the features i want on my primary ddm.

00:40:59 <rust_collector> Lemon, it does not mean the meter can not take more, it is just what they could test it for....if it was tested at all.
00:41:25 <Lemon> yes I know
00:41:32 <Lemon> usually they test them for ten times their ratings
00:41:35 <rust_collector> arrrgh, watcher, I mean
00:41:39 <Lemon> well, good manufacturers
00:41:40 <rust_collector> oh, he is gone
00:42:20 <rust_collector> damnit, is it like I have to read what you people say or something?
00:42:35 <Lemon> well, sometimes at least
00:43:09 <Lemon> honestly if you want a cheap dmm, Id get a fluke 101
00:43:17 <Lemon> and for current just use a random shunt
00:43:25 <Lemon> its not like we measure current everyday
00:43:36 <Lemon> if you have that need you dont buy a 30 euros dmm anyway
00:43:58 <rust_collector> well, it is not exactly difficult to find a regular meter that does current

00:44:58 <rust_collector> quitter
00:45:03 <Lemon> well no but for 30 euros or less, I think it is
00:45:29 <rust_collector> meh. only if you for some reason want to measure more than a few volts

00:45:58 <rust_collector> joiner
00:47:27 <Lemon> the lil fluke 101 honestly feels really really good for 30-35 euros delivered
00:47:36 <rust_collector> sure
00:47:39 <Lemon> pretty nice build quality, well protected
00:47:45 <Lemon> people tested it to thousands volts
00:47:48 * Ampera squeezes Lemon
00:47:53 <Lemon> its accurate enough
00:47:53 * Ampera rusts rust_collector
00:47:55 <Lemon> hey amp !
00:47:56 <Ampera> hullo
00:48:14 <rust_collector> aaaah! I feel the non-energy flowing into my oxide layer
00:49:45 <rust_collector> oh well. i am going back outside, to curse vw engineers again
00:51:57 <Lemon> have fun
01:06:18 <Lemon> ok I need to move my ass and work on the save/load feature
01:06:32 <Lemon> but it feels good to have something working lol
01:10:03 <Lemon> houston we have a problem
01:10:10 <Lemon> I hit clear graph and it froze, lol
01:10:33 <Lemon> ha it did it, didnt crash lol
01:23:20 Quit: hsn93 ([email protected]) Ping timeout: 121 seconds
01:32:44 <rust_collector> arrrfff. so, I am almost done converting my skin to some other substance. I gave up cursing the engineers, now I am just trying to figure out how to find the home address they have
01:34:34 <rust_collector> 98% of the fasteners on these things are on "backwards" so you have to remove large chunks of the car to get to them, or get them off. if they just turned them around, they would be easy
01:36:56 * Ampera wrenches rust_collector into a pretzel, feeds it to T3sl4
01:38:04 <rust_collector> I prefer something like ford, because they just skip installing the hard to get to bolts, lol
01:39:21 <rust_collector> Ampera, did you buy a battery charger?
01:39:50 <Ampera> rust_collector, no I haven't yet
01:40:05 <rust_collector> ok, then I won't ask what you got yet

02:05:08 <Lemon> ok so I just added a excel thingie to build the data so it can be saved/loaded
02:05:18 <Lemon> just 1k samples is enough to make the thing freeze when I hit save
02:05:26 <Lemon> guess there wont be that feature lol
02:35:05 * Ampera excels Lemon into orbit
02:35:44 <Lemon> ;o
04:44:29 <rust_collector> that was that day... what is going on in here?
04:44:59 <Lemon> ho not much, tried to implement a save/load feature by adding an excel thingie, but the problem is that with only 1k samples it freezes
04:45:06 <Lemon> so I just forgot about it
04:46:42 <rust_collector> what did the thing do with the 1k samples?
04:47:08 <Lemon> it was supposed to save an excel file, so I could load it up to build a chart with it
04:47:15 <Lemon> but it froze when I hit the save button
04:47:31 <rust_collector> are you doing something directly to the samples, or are you writing to a file, that a second program can work on
04:47:35 <rust_collector> oh, ok
04:47:42 <Lemon> 1k samples is like, 4 minutes lol
04:48:12 <rust_collector> set it to the 366 day setting, and it will run for hours
04:49:04 <rust_collector> what is an excel file anyway?
04:49:26 <Lemon> microsoft excel you know, the spreadsheet software
04:50:05 <rust_collector> yes, but what kind of file is it? I don't care what program you use to make it
04:50:49 <Lemon> ha its .xlsx
04:51:01 <rust_collector> uhm, yes... but...
04:51:32 <Lemon> I dont understand your question :> its a spreadsheet, you can use excel, openoffice or whatever to open it, the file is .xlsx
04:51:36 <Lemon> theres rows, columns etc
04:51:47 <rust_collector> can you write to a plain text file, and import that to excel, and have excel sort the data for you?
04:52:07 <Lemon> I thought about that but it will be the same problem sadly
04:52:11 Join: DogWomble_ ([email protected]) to #EEVblog
04:52:14 <Lemon> seeing the lag with only 1k samples
04:52:34 <Lemon> I'd need to rewrite everything in C or a better language
04:52:44 <Lemon> its sub-optimized for thousands of datapoints
04:53:01 Quit: DogWomble ([email protected]) Ping timeout: 121 seconds
04:54:50 <rust_collector> but if you write to a file... all the time... it does not process thousands of samples at one time, it does one then one, then one... or maybe you can let them stack up to 500, write those, clear, and sample 500 more?
04:55:22 <Lemon> yeah but I think it acts dumber than that
04:55:28 <Lemon> it tries to read everything at once and crashes
04:55:39 <Lemon> like when I cleared the graph earlier with 500k+ points
04:55:44 <Lemon> it froze for a solid minute lol
04:55:58 <Lemon> so imagine writing to a file in paralel or simply saving/loading
04:56:03 <Lemon> even small batches
04:57:33 <rust_collector> well, you know... do what you want... there has to be a setting in there so you can make it not try to read 39million kiloreadings in one go?
04:58:14 <Lemon> I checked the documentation and sadly not, its either that or nothing.. and I dont have the required skills to write it from scratch
04:59:42 <rust_collector> ok, I do not know what you are working with, so.. not that I know anything anyway, lol.
04:59:51 <rust_collector> so, now... it is dinner time
05:01:21 <rust_collector> like thai say in Japan, carbonara, baby!
05:02:19 <Lemon> nice, I ate some meatballs earlier
05:02:21 <Lemon> was great
05:02:26 <Lemon> now some cereals
05:03:22 <Lemon> also https://www.ebay.fr/itm/200x175x70mm-%C3%89tanche-Bo%C3%AEtier-En-Plastique-Electronique-Jonction-Bo%C3%AEte-Projet-TOP/202699832724
05:03:31 <Lemon> could be nice for the thermometer, I can paint it in black
05:10:46 <rust_collector> yeah, that would work
05:13:01 <Lemon> ho I should add a physical button to reset the readings on the oled display
05:20:01 <Lemon> and date/time record started, total time etc on the software
05:24:43 <rust_collector> hmm, maybe one for each. so you can reset the screen, but keep softwaring?
05:29:39 <Lemon> yeah theres already one on the software
05:29:50 <Lemon> I just need to add a button on the physical thingie
05:29:56 <Lemon> but right now im doing the time elpased etc
05:30:00 <Lemon> elapsed
05:31:56 <rust_collector> keep some space free on the panel, so you can add things later, if you figure out something you want
05:32:42 <Lemon> ho yes theres plenty of space
05:34:12 <rust_collector> yes, but some times you put the buttons and things all over, because it looks nice like that, but then you have no space to add anything later
05:34:33 <rust_collector> I guess making a new front panel is no big deal, but
05:35:30 <Lemon> ho yes I did the mistake tons of time lol I'
05:35:37 <Lemon> I'll show you what it looks in a minute
06:04:59 <Ampera> I have purchased 750sq in. of pizza
06:07:18 <rust_collector> I hope you are hungry
06:07:33 <rust_collector> what is that? 15 pizzas?
06:07:40 <Ampera> rust_collector, 3
06:07:45 <Ampera> three 18" pizzas
06:09:24 <rust_collector> hmmm, I need to either learn math, or have a nap before trying again
06:09:46 * Ampera tucks rust_collector in with a blanket made of pizza
06:09:56 <rust_collector> well, that is good. 3 pizzas should last most of the evening
06:10:14 <rust_collector> mmm, cheese
06:14:08 <Ampera> rust_collector, bacon and mushroom too
06:14:33 <rust_collector> NOOOO!!!!! aaaa my skin is remelting
06:14:43 <Ampera> rust_collector, why
06:14:50 <rust_collector> mushrooms
06:14:54 <Ampera> what's wrong with mushrooms
06:15:10 <rust_collector> they are full of nutrients and stuff
06:15:37 <rust_collector> probably minerals and vitamins and things
06:16:44 <rust_collector> many people get addicted to that stuff, better stay away from it
06:26:53 <Lemon> I think I just wrote the dirtiest piece of code ever
06:26:55 <Lemon> but it works
06:27:02 <rust_collector> good
06:27:37 <Lemon> because fucking vb.net got almost nothing to use as a stopwatch, its either wonky, or you cant customize it at all and it looks like shit, like '0:0:0'
06:27:57 <Lemon> so I wrote something like 'if hours under 10, add a 0 next to hours number' etc lol
06:28:04 <Lemon> that way we have a nicely formated time
06:33:20 <rust_collector> well, that is ok, but where is the dirty part?
06:42:18 <Lemon> well thats not really clean
06:42:25 <Lemon> but now I have a problem, I cant resume the stopwatch
06:42:31 <rust_collector> hah
06:42:32 <Lemon> its too wonky
06:42:42 <rust_collector> remove the first zero
06:48:55 <Lemon> ok I found another function
06:49:00 <Lemon> it seems better
07:04:56 <Lemon> hmmm well it works, its not a ton better
07:05:05 <Lemon> I can get milliseconds smooth, barely seconds
07:05:08 <Lemon> because of the chart
08:15:17 <steve30> Fountain pen really doesn't work very well with carbon paper.
08:15:36 <rust_collector> hmmm. strange

09:46:46 <steve30> hi
09:48:18 <canadaguest> anything interesting to wire up atm steve30?
09:48:21 Join: slo ([email protected]) to #EEVblog
09:51:27 <steve30> nah
09:55:03 <canadaguest> not sure if theres a name for if you just want to buy something alike to pcb but without the copper layer part? like something just for to put a few bolts-mounted components of your own onto it. theres no normal surface-placed components anywhere
09:55:35 * canadaguest had tried look up some generic plastic sheets but ran into low thermal ratings too often so is wondering...
09:56:17 <steve30> I assume you can buy it
09:56:21 <steve30> Not sure where from though
09:57:14 <canadaguest> yeah I'm trying to look into high temperature plastics but its not so easy when I don't know their trading names
09:57:31 <canadaguest> but mm I've got several weeks of leisure to sort this out :)
09:57:44 <steve30> My Dad was asking something similar a few years ago. I wasn't really sure what to recommend.
09:58:22 <canadaguest> but anyhow steve30 I'm just working on my power supply box a bit more tonight, otherwise I don't have a lot else to talk about electronics-wise for tonight :)
10:00:41 <steve30> I should put some 'finishing touches' on my lab PSU some time. The pots and meters are hanging loosely by wires
10:03:29 <canadaguest> not sure if you could give me a second thought on this but lets say a transformer is rated for 120-parallel/240-serial input with say 12vac rms output, I think that if one was to somehow set it to 240v mode but use it on 120v grid instead it would simply output around 6v or would it rather just refuse to output nicely?
10:04:13 <steve30> Should be fine.
10:05:11 <canadaguest> so 6v then?
10:05:42 <steve30> yup
10:23:03 <canadaguest> hm might stay with the manual method for now but I guess the other alternative I was thinking of is to start it initially in 240v mode but with a voltage-comparing circuit on output side .. if it detects 6v it'll signal the input to reroute to 120v state instead. and on power loss it'll default back to 240v state

14:30:01 <MrMobodies> I got this old NSA310 that i use for the network scanner.
14:30:45 <Halcyon> Nice little NAS
14:30:50 <MrMobodies> I took out the drive and put a blank 120gb Sandisk SSD and it failed to write volumes, tried the same one and
14:31:13 <MrMobodies> I tried a Samsung cm871, it worked but really slow of 20mb a second
14:31:20 <Halcyon> Ouch
14:31:21 <Halcyon> That sucks
14:31:36 <Halcyon> A lot of those consumer NAS's are slow as shit. Just underpowered
14:31:54 <MrMobodies> I tried an older Samsung SSD pm851 Sata 2 2012 and it works good
14:32:29 <MrMobodies> Does about 60mb like the other drive but the when accessing pictures it seems much quicker
14:33:12 <MrMobodies> I took out a 1gb Hitachi it was getting hot in there I don't need all that space
14:33:16 <MrMobodies> for what it is used for
14:33:55 <MrMobodies> Hitachi 1TB 5V 450MA/ 12V 700ma
14:34:08 <MrMobodies> Samsung PM851 0.5A
14:35:13 <MrMobodies> Samsung CM871 Sata 6GBPS 5V 1.1A (very slow write speeds in the NAS)
14:35:58 <MrMobodies> Sandisk SSD X110 5V 1.6A fails to format but the partitions seems to be created
14:36:36 <MrMobodies> strange how it can vary like that
14:36:59 <MrMobodies> I thought they all performed to a standard
14:37:54 <MrMobodies> the higher performance drives seem to perform crap but the older slower SSD or the drive I pulled out works better
14:39:37 <MrMobodies> I use it for the network scanning from a HP 8620
14:39:57 <MrMobodies> Brought that in January 2016 and no problems with it seems very reliable
14:41:29 <MrMobodies> Got to go to sleep now

20:46:10 <Lemon> I thought it was just an amp, but no its also an am/fm receiver !
20:46:30 <Lemon> I hooked a double antenna I salvaged from whatever, but im getting only noise
20:46:54 <Ampera> mmm, radio
20:48:05 <Lemon> maybe im doing something wrong
20:48:24 <Lemon> I just never used one, besides some that were already on and I just had to rotate a pot to change the station
20:48:26 <Ampera> Lemon, let's start with the basics. Do they have radio in france?
20:48:33 <Lemon> we do yes x)
20:48:46 <Ampera> is it FM and/or AM radio
20:49:47 <rust_collector> that should make some noise. have fun
20:49:55 <rust_collector> I am going to work...
20:49:56 <Lemon> its an am/fm one
20:50:05 <rust_collector> yes, but radio in france
20:50:06 <Ampera> no, does france have AM/FM radio
20:50:07 <Lemon> I can switch between both, and change freq but noise on everything right now
20:50:16 <Lemon> ha I guess ?
20:50:17 <rust_collector> mostly fm, I guess
20:50:29 <Ampera> because some strange European nations have done silly things like turn on the AM and FM broadcasts
20:50:39 <Ampera> because, you know, nobody owns an AM/FM radio
20:51:17 <Lemon> https://www.radio.fr/country/france
20:51:17 <K> i think we don't have AM anymore, FM is still quite popular
20:51:51 <Ampera> We will likely never turn off our AM/FM radio broadcasts, as we already have a compatible digital radio system
20:52:05 <Ampera> They'll end when consumer interest ends
20:52:24 <Lemon> ha !
20:52:28 <Lemon> im getting something
20:53:07 <Lemon> not the best quality ever but
20:53:16 <Lemon> I can listen to some random benabar, erk
