[04:18:40] <theBear> heh, you guys got funny cartoon soundey names... i like it !
[06:18:19] <veverak> well
[06:18:44] <veverak> let's say I will get inspired wit algorithms from academic papers
[06:18:55] <deshipu> unpossable!
[06:19:05] <veverak> and I code some opensource thing based on that and mention the credits/inspiration
[06:19:17] <veverak> -> that's afaik everything I need to do?
[06:19:19] <veverak> :)
[06:20:00] <deshipu> algorithms are not copyrighted
[06:20:06] <deshipu> or patented
[06:20:12] <deshipu> you cannot patent math
[06:20:24] <veverak> yeah, just making sure
[06:20:27] <deshipu> in civilized countries, that is
[06:20:44] <deshipu> you can give credit if you like, it's nice to do so
[06:20:58] <veverak> I inted to and I will do
[06:21:00] <veverak> :)
[06:22:25] <deshipu> it may also make sense to write to the original researchers with "look, there is a real world application!"
[06:22:38] <deshipu> some of them would be happy to see it
[06:23:25] <veverak> :)
[12:31:15] <LiohAu> just learned two new words: "outrunner" and "inrunner" motors, can't find a translation anywhere, what does that mean ?
[12:31:31] <deshipu> LiohAu: which part of the motor rotates
[12:31:44] <deshipu> LiohAu: inrunners are like normal motors -- the shaft is connected to the inside
[12:32:05] <deshipu> LiohAu: outrunners have the inside mounted to something, and the outside rotates
[12:32:16] <jhylands> https://en.wikipedia.org/wiki/Inrunner
[12:32:22] <LiohAu> hm so that makes large motors, no?
[12:32:23] <jhylands> https://en.wikipedia.org/wiki/Outrunner
[12:32:59] <LiohAu> jhylands: obviously I did not find these pages myself :P
[12:33:18] <jhylands> google "brushless motor inrunner outrunner"
[12:33:21] <jhylands> without the quotes
[12:35:06] <myself> 3.5" floppy and cdrom motors are mostly outrunners
[12:35:19] <myself> 5.25" floppy drives were built with both, depending on the era
[12:36:49] <LiohAu> so if I understand correctly, this word only has a meaning for brushless motors, right?
[12:36:53] <LiohAu> these words*
[12:37:16] <jhylands> well, I don't know if "only" is correct, but it certainly applies to them
[12:37:53] <jhylands> http://www.gizmag.com/outrunner-running-robot/31999/
[12:38:05] <Snert_> seems like a brushed inrunner would be the average everyday motor.
[12:38:24] <Snert_> so no real significance there.

[15:12:39] <Snert_> these guys get to do all the coolest stuff.
[15:13:00] <Snert_> to just play with robots all day and get paid for it :(
[15:13:18] <Snert_> I'm in the wrong job
[15:27:49] <deshipu> it's in my city
[15:28:00] <deshipu> maybe I should look for a phd there :)
[15:29:35] <deshipu> I mean ETH
