| 13:25.05 | eintopf | they told the most are in african |
| 13:25.18 | eintopf | and it's difficult to get them because war |
| 13:25.25 | eintopf | another question |
| 13:25.44 | eintopf | what are the benefits exactly smd led and a normal led |
| 13:25.55 | eintopf | except the form factor |
| 13:26.16 | whitequark | eintopf: there's the congo minerals |
| 13:26.36 | whitequark | but congo doesn't contain *most* tantalum, neither it even supplies the majority of it used today |
| 13:26.54 | whitequark | typical telly fud |
| 13:27.05 | whitequark | and there's no difference except the form factor |
| 13:27.21 | eintopf | http://uclu.org/sites/uclu.org/files/cfci_image_1_copy.jpg |
| 13:27.22 | eintopf | ahh |
| 13:28.46 | eintopf | yea, but mean "bloody hands" in this case because the situation |
| 13:29.00 | eintopf | how to get the resource, child work, not safety |
| 13:29.44 | eintopf | now I never wants to buy a new smartphone |
| 13:30.06 | eintopf | and the google guy already laughed about me because I have currently an old nexus 4 |
| 13:30.09 | eintopf | ... |
| 13:30.14 | eintopf | with half broken display |
| 13:30.18 | whitequark | that picture is bullshit |
| 13:30.43 | whitequark | just like anything else with extraordinary claims and no sources |
| 13:31.36 | eintopf | http://ddc.arte.tv/folge/mobiltelefonie-2-2-die-dunklen-seiten |
| 13:31.41 | eintopf | I saw this documentation |
| 13:31.46 | eintopf | but it's in german |
| 13:32.03 | eintopf | they told the same, it's like blood diamonds but they name it blood minerals |
| 13:32.06 | whitequark | I don't know german unfortunately |
| 13:32.08 | eintopf | :( |
| 13:32.30 | whitequark | yes, blood minerals, conflict minerals, etc, are a problem that exists |
| 13:32.41 | whitequark | DRC coltan is the major manifestation |
| 13:33.09 | whitequark | however, there are regulations in place in EU and US that require tracking the supply chain of coltan, likewise with diamonds |
| 13:33.18 | eintopf | I see |
| 13:33.22 | whitequark | so saying that iphones rely on conflict tantalum is incorrect |
| 13:33.31 | eintopf | ahh |
| 13:33.32 | eintopf | okay |
| 13:33.34 | whitequark | what *is* correct is that iphones are assembled on a foxconn factory with ~400 suicides per year |
| 13:34.10 | eintopf | ok |
| 13:34.30 | whitequark | well, probably lower now, since there was an outrage over this, but I doubt the conditions there improved all that much |
| 13:35.23 | eintopf | ok. |
| 13:36.06 | eintopf | and another question about wire, I have some of these magnetic wire |
| 13:36.19 | whitequark | you mean varnish-covered magnet wire? |
| 13:36.29 | eintopf | I need to google it, wait |
| 13:36.39 | eintopf | yes |
| 13:36.57 | eintopf | it looks exactly like that, when I solder at the line the isolation will be gone |
| 13:37.29 | whitequark | I recommend clearing the varnish before soldering, it can interfere with forming of the joint |
| 13:37.30 | eintopf | but I think it has a different name |
| 13:37.58 | whitequark | burn it off with cigarette lighter. sandpaper also works in a pinch, but much slower |
| 13:38.25 | whitequark | it's also called "transformer wire" |
| 13:38.27 | eintopf | can I use that wire also when it lays inside a electric cicruit? |
| 13:38.34 | whitequark | "inside"? |
| 13:38.44 | eintopf | on some board components, etc |
| 13:38.50 | whitequark | yes |
| 13:38.58 | whitequark | keep in mind that sharply bending it will flake off the varnish |
| 13:39.09 | eintopf | ah, not bending it. Ok |
| 13:39.12 | whitequark | for a thin hookup wire, I recommend PTFE-coated wire |
| 13:39.19 | whitequark | multistrand |
| 13:39.30 | eintopf | and these are so small, I could use them directly @ smd led |
| 13:41.17 | eintopf | or should I use "kynar wire" |
| 13:41.18 | eintopf | mhh |
| 13:41.40 | eintopf | because all people use kynar wire |
| 13:42.13 | whitequark | kynar is another fluorinated polymer |
| 13:42.24 | whitequark | should be at least as good as PTFE |
| 13:42.28 | whitequark | so go ahead |
| 13:43.06 | whitequark | pvdf (kynar) to ptfe is what pvc is to pe |
| 13:44.29 | eintopf | ok. |
| 13:45.55 | whitequark | generally... all fluorinated polymers offer excellent physical and chemical resistance |
| 13:46.11 | whitequark | as long as cost allows i always prefer them |
| 13:59.41 | roh | is pvdf also self-lubricating? |
| 14:00.07 | roh | like ptfe and pom :) |

| 14:30.05 | whitequark | no idea here |
| 14:31.45 | whitequark | looks like not |
| 15:36.59 | DocScrutinizer05 | ((foxconn factory with ~400 suicides per year)) they mounted nets so jumping out the window doesn't work anymore for suicide |
| 15:37.33 | DocScrutinizer05 | dunno if they also did anything else to actually improve the situation, prolly not |
| 15:57.00 | whitequark | I think they made some minor concessions |
| 15:57.15 | whitequark | but that doesn't really change anything |
| 15:57.48 | whitequark | DocScrutinizer05: btw, import feature almost ready to ship... |
| 15:57.53 | whitequark | in solvespace |
