48:34 <WebChatUser242424> hello, is this an appropriate place to ask basic questions about lab setup?
49:49 <Ampera> If you want.
50:06 <Ampera> People may or may not be on to answer it, but we often answer whatever we can.
50:16 <Ampera> If you become impatient, the forum is also a decent place.
50:40 <WebChatUser242424> My question is mostly about table surface; the table I have access to right now is made of high-density polyethylene (hdpe) plastic -- is this fine or is it potentially problematic?
51:25 <WebChatUser242424> I don't know the properties of plastic well enough to know if there would be any problems there as opposed to wood (which I would assume is ideal?)
55:02 <Ampera> Problematic for what?
55:28 <Ampera> Generally when working with electronics it's a good idea to have an ESD safe working surface. Wood is alright for this in a pinch, but most plastics are not.
55:44 <Ampera> Dave, for example, uses ESD safe mats which don't conduct or dissipate static electricity.
55:56 <Ampera> however if you're working with birdhouses, HDPE is perfectly fine.
00:21 <WebChatUser242424> I do have an ESD-safe rubber work mat thing but I just didn't know if there would be any risk to having the power supply or oscilloscope sitting off to the side on the table surface, or my soldering iron, etc.
00:59 <WebChatUser242424> Since from time to time I do seem to feel a blanket of static on the table surface from the hairs on my forearms as I brush past
01:35 <Ampera> No, the danger is primarily with unplugged electronics. Plugged in electronics are either grounded or insultated so that they don't have electrical contact to the outside.
02:00 <Ampera> I'd imagine it would be fine for bench tools.
02:18 <WebChatUser242424> So as long as everything is plugged in and I'm not leaving any unplugged tools on the table surface, and I'm doing my work on the rubber mat, I should be OK?
05:56 <Ampera> Pretty much.
06:16 <Ampera> I mean if you're really concerned you could also put a thin peice of wood between the table and your electronics.
21:41 <WebChatUser242424> Thanks Ampera
24:48 <Ampera> np

04:25 <rust_collector> very morning to you mr sir
30:27 <Ampera> dow jones is going insane.
31:09 <rust_collector> bit late to think about that now, isn't it?
36:13 <Ampera> ?
36:54 <rust_collector> yes, that is what I thought
37:03 <Ampera> I have no clue what you're going on about
37:09 <rust_collector> anyway, what is it doing?
37:23 <Ampera> going up and down
37:27 <Ampera> a lot
37:44 <rust_collector> I used to enjoy bouncing around
39:56 <rust_collector> Distilling & Cattle Feeding Company... that is a catchy name

06:30 <IoTPanic> Very.... is it like a grain company or?
06:44 <IoTPanic> Im trying to see the overlap of distilling and cattle feeding
09:01 <rust_collector> not sure, it says it is now LyondellBasell
10:13 Join: Guest|54713 ([email protected]) to #EEVblog
10:51 <Guest|54713> im looking for that video dave made with some scope or some measurement tool that was skewed simply because it was tilted up with the stand
10:55 <Guest|54713> If anyone can recall which video that was
10:56 <Guest|54713> lol
17:01 <cappicard> i've been watching videos about the now infamous weller soldering station... wow... no fuse on the primary side of the transformer.
17:51 <cappicard> i'm not an expert on electronics by any stretch, even I see the danger of not having a fuse on something like that.
19:31 <rust_collector> To me, it looked like the transformer was made from a material that would instantly short the whole thing, and trip your breaker.... I should sell that idea to weller
21:36 <cappicard> the insulation on the primary coil seemed rather thin.
22:49 <cappicard> pretty sad that even the cheap chinese station was fused.
23:56 <rust_collector> now that you mention that. I saw a video about something yesterday, or the day before... It did have a fuse, but it was not connected to anything
24:58 <cappicard> dave did a video a few years ago about the cheap chinese station. i immediately thought of that teardown when i saw the magic smoke video.
25:33 <rust_collector> the yaahoo station?
26:13 <rust_collector> yeehaw
27:16 <cappicard> yeah, the yehua or however it's spelled.
27:24 <rust_collector> I have one. it works pretty ok
27:32 <rust_collector> yihua
27:37 <cappicard> that's it.

30:06 <IoTPanic> I dont always choose to use a fuse, but when I don't you can be sure I bought a weller (Said in that beer commercial voice)
32:35 <cappicard> i still have one of those old radio shack irons. just good enough for a quick soldering job here and there.
33:50 <IoTPanic> I had an old radio shack station when I was learning, used it all through middle and high school. The temp was NOT accurate but the thing was a god damn brick
35:37 <rust_collector> this yeehaw is my first station. I have always used the little 25-ish watt irons
35:51 <rust_collector> well, and the big ones, but yeah
36:59 <rust_collector> On the little irons, I used to wear out the tip, and... buy a new iron, because the tips were expensive
37:32 <rust_collector> And they usually had a litle setscrew that stripped out, or disappeared
05:37 <rust_collector> wth? "gaming power strip" with rgb leds, lol
27:15 <ThunderSqueak> hi rust_collector
27:30 <rust_collector> hellos
27:40 <ThunderSqueak> new iron?
27:43 <ThunderSqueak> :D
27:46 <rust_collector> nope
27:52 <ThunderSqueak> aww
28:05 * ThunderSqueak uses an ADS200 currently
28:10 <ThunderSqueak> that or the old hakko
28:41 * rust_collector uses a crappy yeehaw 936 thing, which works just fine
29:46 <ThunderSqueak> do not think I will ever buy the older style irons again, too spoiled now
30:24 <rust_collector> So. I found a pair od 50w 6ohm resistors in the random junk bit at work. I have no idea what I would need them for, but they do look cool
31:16 <rust_collector> those extruded and anodised aluminum things
32:03 <rust_collector> But I also enjoy looking at certain metal parts. Like inside a hard drive. I just think they are very pretty
32:44 <ThunderSqueak> hmmm http://www.dumpaday.com/wp-content/uploads/2011/05/fortune-cookie-rectal-use-only.jpg
33:26 <rust_collector> I am not sure what sort of iron I would get when this thing fails.
34:35 <rust_collector> It is not like soldering is my job, so even if I might like nice and awesome things, cheap-ish will probably win
35:16 <ThunderSqueak> *nodnod*
36:17 <rust_collector> otoh, I guess this cheap pos will just keep working forever
21:55 <DHess_US> There is only a requirement for a fuse for operator safety meaning that it does not matter if the soldering station destroys itself as long as it does not cause a fire.
22:41 <DHess_US> Thick billowing toxic smoke is no problem but if it can catch on fire, then a fuse is required to prevent that.
24:13 <DHess_US> They could have used a fusible link in the transformer but that would just mean some extra failures where the soldering station becomes equally useless.

50:39 <DHess_US> Lol, YouTube video "Why are There No B Batteries?" Haha. That's funny.
52:40 <DHess_US> Patreon is the gift which keeps giving. https://www.youtube.com/watch?v=DpdnzWV3sYI
52:59 <IoTPanic> How is patreon compared to high ranking Nazi officials? I'm a little lost on that.
08:10 <coppice_> The video is a meme, to which people add relevant subtitles for the current context
10:45 <coppice_> but the comparison is reasonable. Authoritarians who think people can be crushed into submission

29:43 <Ampera> Compiling barely strung together packages to compile other barely strung together packages for some obscure program is one of the best parts of Linux.
30:35 <Ampera> A game I want to compile (SRB2) for Linux requires gcc 4.7, which is available on the AUR, but it's one of those packages that won't just install, because one of the handful of dependencies off the AUR has broken.
31:01 <Ampera> What I find amusing is I'm using what is presumably gcc to compile gcc.
31:50 Quit: hsn ([email protected]) Ping timeout: 121 seconds
34:01 <andtfoot__> Is there something special about gcc 4.7, or is it just an arbitrary requirement by the SRB2 dev(s)?
34:14 <andtfoot__> (I'm not really a Linux person)
35:37 <Ampera> Presumably it supports an alternate standard of C (C11 or maybe even C99), that it altered/not supported in GCC 8, or even the interface to the entire program has changed in some way.
39:05 <andtfoot__> Fair enough; I can't say I'd even thought that were would be non-backwards compatible support of C standards. The more you know... :)
40:42 <andtfoot__> It's been my general experience of Linux though... spending more time chasing random dependencies and incompatabilities of various packages, etc than actually using it.
41:18 <Ampera> This is a very niche program and a small part of modern Linux, at least as far as Arch is concerned.
41:44 <Ampera> I rarely have to do any of this, and only ever when I go hunting around for strange software.
43:08 <andtfoot__> So was the program worth it? :D
43:16 <Ampera> haven't compiled it yet
43:28 <Ampera> I might end up stealing the binaries off the debian repos if I can manage that.

09:48 <T3sl4> Ampera: sonic doom?
10:14 <Ampera> Yeah, it's actually a very competent, fun to play 3D sonic game implemented in the Doom engine.
10:43 <T3sl4> is that not simply a matter of downloading current gzdoom or zandronum, and the wad/pk3?
10:44 <Ampera> It has platforming, badniks, good level design (except the last one), and good art.
10:58 <Ampera> No, that's if it uses the same, unmodified doom engine as the original doom.
11:06 Quit: DogWomble_ ([email protected]) Ping timeout: 121 seconds
11:12 <Ampera> This is a modified doom legacy, with engine alterations and additions to make it an actual sonic game
11:20 <T3sl4> hmm
11:42 <Ampera> You should give it a look, it's a very impressive game, and has been around for over 20 years in one form or another.
11:48 <Ampera> Netplay is also immensely fun too.
11:57 <Ampera> srb2.org
14:36 <Ampera> T3sl4, I can stream it real quick and you can see what it looks like
14:50 <T3sl4> nah, i get the basic idea
15:13 <Ampera> :(
15:16 <Ampera> now I have no reason to stream it
