eintopf | they told the most are in african | 13:25 |
---|---|---|
eintopf | and it's difficult to get them because war | 13:25 |
eintopf | another question | 13:25 |
eintopf | what are the benefits exactly smd led and a normal led | 13:25 |
eintopf | except the form factor | 13:25 |
whitequark | eintopf: there's the congo minerals | 13:26 |
whitequark | but congo doesn't contain *most* tantalum, neither it even supplies the majority of it used today | 13:26 |
whitequark | typical telly fud | 13:26 |
whitequark | and there's no difference except the form factor | 13:27 |
eintopf | http://uclu.org/sites/uclu.org/files/cfci_image_1_copy.jpg | 13:27 |
eintopf | ahh | 13:27 |
eintopf | yea, but mean "bloody hands" in this case because the situation | 13:28 |
eintopf | how to get the resource, child work, not safety | 13:29 |
eintopf | now I never wants to buy a new smartphone | 13:29 |
eintopf | and the google guy already laughed about me because I have currently an old nexus 4 | 13:30 |
eintopf | ... | 13:30 |
eintopf | with half broken display | 13:30 |
whitequark | that picture is bullshit | 13:30 |
whitequark | just like anything else with extraordinary claims and no sources | 13:30 |
eintopf | http://ddc.arte.tv/folge/mobiltelefonie-2-2-die-dunklen-seiten | 13:31 |
eintopf | I saw this documentation | 13:31 |
eintopf | but it's in german | 13:31 |
eintopf | they told the same, it's like blood diamonds but they name it blood minerals | 13:32 |
whitequark | I don't know german unfortunately | 13:32 |
eintopf | :( | 13:32 |
whitequark | yes, blood minerals, conflict minerals, etc, are a problem that exists | 13:32 |
whitequark | DRC coltan is the major manifestation | 13:32 |
whitequark | however, there are regulations in place in EU and US that require tracking the supply chain of coltan, likewise with diamonds | 13:33 |
eintopf | I see | 13:33 |
whitequark | so saying that iphones rely on conflict tantalum is incorrect | 13:33 |
eintopf | ahh | 13:33 |
eintopf | okay | 13:33 |
whitequark | what *is* correct is that iphones are assembled on a foxconn factory with ~400 suicides per year | 13:33 |
eintopf | ok | 13:34 |
whitequark | well, probably lower now, since there was an outrage over this, but I doubt the conditions there improved all that much | 13:34 |
eintopf | ok. | 13:35 |
eintopf | and another question about wire, I have some of these magnetic wire | 13:36 |
whitequark | you mean varnish-covered magnet wire? | 13:36 |
eintopf | I need to google it, wait | 13:36 |
eintopf | yes | 13:36 |
eintopf | it looks exactly like that, when I solder at the line the isolation will be gone | 13:36 |
whitequark | I recommend clearing the varnish before soldering, it can interfere with forming of the joint | 13:37 |
eintopf | but I think it has a different name | 13:37 |
whitequark | burn it off with cigarette lighter. sandpaper also works in a pinch, but much slower | 13:37 |
whitequark | it's also called "transformer wire" | 13:38 |
eintopf | can I use that wire also when it lays inside a electric cicruit? | 13:38 |
whitequark | "inside"? | 13:38 |
eintopf | on some board components, etc | 13:38 |
whitequark | yes | 13:38 |
whitequark | keep in mind that sharply bending it will flake off the varnish | 13:38 |
eintopf | ah, not bending it. Ok | 13:39 |
whitequark | for a thin hookup wire, I recommend PTFE-coated wire | 13:39 |
whitequark | multistrand | 13:39 |
eintopf | and these are so small, I could use them directly @ smd led | 13:39 |
eintopf | or should I use "kynar wire" | 13:41 |
eintopf | mhh | 13:41 |
eintopf | because all people use kynar wire | 13:41 |
whitequark | kynar is another fluorinated polymer | 13:42 |
whitequark | should be at least as good as PTFE | 13:42 |
whitequark | so go ahead | 13:42 |
whitequark | pvdf (kynar) to ptfe is what pvc is to pe | 13:43 |
eintopf | ok. | 13:44 |
whitequark | generally... all fluorinated polymers offer excellent physical and chemical resistance | 13:45 |
whitequark | as long as cost allows i always prefer them | 13:46 |
roh | is pvdf also self-lubricating? | 13:59 |
roh | like ptfe and pom :) | 14:00 |
whitequark | no idea here | 14:30 |
whitequark | looks like not | 14:31 |
DocScrutinizer05 | ((foxconn factory with ~400 suicides per year)) they mounted nets so jumping out the window doesn't work anymore for suicide | 15:36 |
DocScrutinizer05 | dunno if they also did anything else to actually improve the situation, prolly not | 15:37 |
whitequark | I think they made some minor concessions | 15:57 |
whitequark | but that doesn't really change anything | 15:57 |
whitequark | DocScrutinizer05: btw, import feature almost ready to ship... | 15:57 |
whitequark | in solvespace | 15:57 |
