whitequarkDocScrutinizer05: http://www.youtube.com/watch?v=oDAw7vW7H0c11:25
DocScrutinizer05oh yeah, noobs 11:25
DocScrutinizer05I already had my rant on this, over in #maemo11:25
DocScrutinizer05yesterday iirc11:26
DocScrutinizer05whitequark: nevertheless thanks for pointing me at it11:26
larscthe video is good though11:28
whitequarkDocScrutinizer05: remind me, how much phones did you work on? three? :)11:29
DocScrutinizer05minimum three. Isn't that enough?11:29
whitequarkmore than11:29
DocScrutinizer05larsc: which is the problem indeed11:30
DocScrutinizer05the video makes sense, to those without any clue about EE11:30
larscand that's what it's all about11:31
Action: whitequark nods11:31
whitequarkI'll just point people to your rant.11:31
whitequark(which is why I have shown you it in the first place :)11:31
DocScrutinizer05even dos1 who's not an EE noticed "sure, a cpu has a few more than 4 pins"11:31
DocScrutinizer05I may add considerations about mere geometrics of the whole device, like positioning of aerials etc11:32
DocScrutinizer05modules with exceptional height like cam module11:33
DocScrutinizer05modules that need 532 pins11:33
larscwho needs more than 3 pins anyway? gnd, vcc and one-wire communication11:34
whitequarkwho needs more than 0.01FPS anyway?11:34
DocScrutinizer05honestly, Option GTM801 module is as good as it possibly gets, regarding this idea of modularity11:35
DocScrutinizer05this video probably made by designers11:37
DocScrutinizer05dang you, qibot!11:37
DocScrutinizer05oops, correction: it was kerio to notice "clearly, a cpu only needs 4 pins", not dos112:09
wpwrak"This video is currently unavailable." what did i miss ?12:11
whitequark"hi-freq connectors are expensive" "it's a challenge. let's make cheaper connectors."12:13
whitequark"let's use usb. for camera and display panel"12:13
whitequark"ok, usb doesn't work, let's use hdmi for display instead"12:14
whitequark"clearly it is possible to at least upgrade RAM size"12:14
whitequark(from our internal chat)12:14
whitequark"yeah, connectors are expensive, but I totally would solder that"12:15
whitequarkhe was fucking serious all the time12:15
DocScrutinizer05wpwrak: maybe they recognized how much nonsense it been, and took it down?12:15
whitequarkplease excuse me while I'd cry down in a corner12:15
Action: DocScrutinizer05 hands whitequark a lolly12:16
whitequarkwpwrak: still works for me12:16
whitequark"companies are opposed to modular design because this means they'll get to sell less phones"12:17
whitequark"yeah, it works for notebooks this way too"12:17
Action: whitequark headdesks12:17
larscwhom are you talking to?12:19
whitequark*cough* colleagues *cough*12:21
cdehi larsc 12:26
cdehow are you?12:26
larscI'm fine12:27
wpwrakah, a general rant.12:27
DocScrutinizer05whitequark: start with a "simple" thing: make WLAN a module! Ask your colleague how to handle that on a embedded level. What to do when the next chip doesn't use SPI but any arbitrary other interface?12:33
cdejust use a otherinterface-to-spi bridge ;) like pcie to spi, problem solved12:34
DocScrutinizer05or go for modem. One uses USB, one "usb"-ULPI, one fast-UART, the next usues shared RAM, the next ... You see?12:34
wpwrakcde: wrong12:34
cdeI was trolling, wpwrak 12:35
wpwrakcdw: the correct answer is: "use an Arduino" !12:35
cdehaha true :)12:35
cdeor maybe a raspberry pi would be perfect12:35
wpwrakDocScrutinizer05: you can bit-bang 'em all :)12:36
DocScrutinizer05(modem) some come with GPS, some even with MiMO (multi aerials) for diversity. You're going to have ~6 general-purpose antenna connectors on your generic modem module socket?12:37
DocScrutinizer05wpwrak: yep, clearly the silicon doesn't do anything else ;-)12:38
whitequarkDocScrutinizer05: their answer to that is "let's just use usb for everything"12:38
DocScrutinizer05in the end everything is just bitbang12:38
whitequarkand obviously no clue about aerials12:39
whitequark"well there should be some way"12:39
DocScrutinizer05whitequark: my answer to *that* is: USB is about as bad as it gets for a general purpose low power interface12:39
whitequarkyou understand that. I understand that. average joe has a bunch of USB peripherals which "just work"12:40
wpwraki would nominate PLC :)12:40
DocScrutinizer05your modular phone based on "USB for everything" will hardly work >3h even on a bulky battery12:40
wpwraka very reasonably-sized car battery should do just fine12:41
whitequark"well, ten years ago we had brick-sized phones and now we have 100000 more powerful ones in a fraction of size!"12:41
DocScrutinizer05you can even make a BLOK out of it12:41
DocScrutinizer05yes, thanks to specialization in interfaces12:42
DocScrutinizer05thanks to MIPI HSI etc12:42
DocScrutinizer05nix USB12:42
whitequarkthe ultimate answer to "no, it's not possible with current tech" is "dude why are you so boring"12:42
DocScrutinizer05stop that discussion, it's futile12:42
whitequarklong ago12:43
larscwell, people should be allowed to dream12:43
whitequarkit's just those guys whose solution for every problem is an arduino. very cringeworthy.12:43
whitequark(that's not even a metaphor)12:43
larscwell if all you have is an hammer...12:44
whitequark... you will very likely soon miss a finger or two12:44
whitequarkwhat were we talking about again?12:44
DocScrutinizer05and peel your eggs with a hammer12:44
DocScrutinizer05and spread the butter on your toast with a hammer12:45
wpwraknow we know how the nutritional value of egg shell fragments in scrambled eggs was discovered12:45
DocScrutinizer05and claim "a hammer is an awesome tool, look what I can do with it"12:45
wpwrakand then you become a dentist ...12:46
