DocScrutinizer05c) for inserting amp-meter10:28
DocScrutinizer05prolly one of the most common usages10:29
wpwrak_ah yes, makes sense to distinguish this from a)12:48
nicksydneyDocScrutinizer05: you mean to measure current for (c) ?12:50
nicksydneygot delivery of this today http://www.ebay.com/itm/310717070508 and saw the datasheet for the boost regulator http://ja3hsv.blog.ocn.ne.jp/blog/files/xl6009e1-switch-mode-ic.pdf and there is calculation to calculate the voltage output - 1.25 *(1+R2/R1) ... how did they get 1.25 from ?12:52
wpwrak_hmm. just got a newsletter "Spansion Quarterly News". one of their headlines: "News: Spansion Plays Hardball With Patents". goes on with12:52
wpwrak_"In addition to the company's on-going legal battle with Taiwan's Macronix, Spansion is now turning up the heat on anyone"12:52
wpwrak_they have an interesting concept of advertizement ;-)12:53
nicksydneyDocScrutinizer05: "c) for inserting amp-meter"12:53
DocScrutinizer05yes, that's the use of an ampere-meter12:54
DocScrutinizer05you frequently use 0R to open up a trace to insert an ampere-meter to check power consumption of some subsystem12:55
nicksydneyinteresting..so it's like putting a "breakpoint" in software :)12:55
nicksydneyor put a logging :)12:55
larscwpwrak_: maybe that was a shareholder newsletter 12:57
DocScrutinizer05when you may do that regarding circuit, you also may decide to use a 0.01Ohm resistor instead, and simply probe for the voltage across it12:57
wpwrak_or maybe i accidently got on the patent troll mailing list ;-)12:58
DocScrutinizer05not as simple as an ampere-meter, but more convenient in other aspects12:58
nicksydneyDocScrutinizer05: if you design something when or where do you normally place 0.01resistor ?12:59
nicksydneyis it when you are uncertain of something as you are still developing the design ?13:00
DocScrutinizer05yes, for example13:44
wpwrak_#ifdef :)13:46
whitequarkwhat the fuck exactly is russian post trying to do here? http://gdeposylka.ru/RB986639092HK17:48
whitequarktl;dr: they have sorted it three times, delivered it to the post office two times, and now it's sorting the fourth time17:49
whitequarkI don't even17:49
whitequarkwere the first two times too quick for them?!17:50
larscretry until it ends up in the right place18:47
whitequarklarsc: udging by te indexes tey already sent it to te rigt oice twice19:38
whitequark9keyboard problems i know019:38
whitequarker not indexes but ipcodes19:38
whitequarktis is so annoying :(19:39
larscwell maybe it is some kind of onion routing19:40
whitequarkor tey're ust playing pong19:41
whitequarki wonder i parcels ae ttl and wat appens wen it expires19:42
larscone of the postal workers takes it home19:42
wpwrak_so that's how whitequark types when he's very excited ? or is it just the vodka ? :)20:33
whitequarkwpwrak_: I've told you about that hairline crack in my keyboard earlier20:37
whitequarkso when I'm near my bluetooth one which is too heavy to carry around, I type properly20:37
whitequarkotherwise it's what you can see above20:37
