DocScrutinizer05wpwrak: not beer at 35°, but fridge that works absorber with gas heating (some even can take candle for power source ;-D )00:53
DocScrutinizer05during daytime probably even solar power will work to freeze your beer, the more sun the colder00:53
DocScrutinizer05you find those critters in mobile homes aka campers usually00:54
DocScrutinizer05nice design: not a single moving part (except door)00:55
DocScrutinizer05so i guess that's what you call "solid state"00:55
wpwrakheh, i know that type. my parents had one. "early years of the 20th century" bah, well into the 1980es01:10
wpwraksolar panels are risky, though. we get rather strong winds around here. and intense hailstorms.01:11
wpwrakso fixed solar panels would get smashed about 3 times per year. unless you make them considerably stronger than a car roof. movable panels could become victims of those little tornados.01:12
rohwell... do the math. around here if your building is big enough and you need enough thermal power even small gas motors with exhaust power reuse make sense economically01:13
wpwrakyeah, most blackouts are well below 24 hours. and the big ones are highly clustered. so a permanent installation doesn't really make sense.01:17
rohi see... well.. buy a high powered generator, sit it out on gas01:18
rohor is there a reliable natural gas grid?01:18
wpwrakpossibly. so far it was reliable but i don't know at what point it may fail, too01:20
wpwrakand no, i wouldn't get a BIG one. i'm not strong enough to move around a 100 kg machine01:21
wpwrakbesides, the bigger ones are shit quality01:21
wpwrakwhis one looks nice, though: http://www.yamahaef2000is.com/01:22
wpwrakalas, cost almost 3x as much as a cheap one with similar characteristics01:22
rohbig is from my perspective 5-15kw01:25
rohenough to power an normal nerd household01:25
rohbasically a small 3-phase power generator with electric starter01:25
wpwrak5 kW+ is huge. not movable.01:25
rohsomething which could, combined with ups could turn on automatically01:26
rohsure.. 5kw is small.. think honda with a handle01:26
wpwrakyeah, right. i'm not trying to build a cult around the power failures :)01:26
roh15 is like a small air compressor. 2 wheels and a handle01:26
wpwrakabout 150-200 kg, i guess01:27
wpwrakor very very very expensive but a but lighter01:27
wpwrakalready the cheap 2 kW ones are about 50 kg01:27
wpwrak7.5 kW .. 92 kg01:29
wpwrakthat's the top of that range. let's see what the competition has ...01:29
wpwrakah, here's one: 16 kV, 176 kg01:32
wpwrakbut indeed, that one could also supply most of my air conditioners ;-)01:33
rohhm. the last small honda i handled we carried up stairs with 2 or 3 persons01:33
rohabout 5kw, 2 phase output01:33
wpwrak2-3 persons for 50 kg that sounds about right01:34
rohshouldnt 5kw already be enough when you leave the airco out of the picture?01:34
rohthat was the last big outage i remember in berlin01:34
rohabout 5-7 years ago.. about 1 hour...01:35
wpwraknow, when power fails, i would either have to summon people to my place to carry the generator up to the terrace, kinda difficult if the power is out01:35
wpwrakor drag it there myself01:35
rohwe took the event to start up and then service the generator... the battery was dead.. so we carried it to a car and bridged them01:35
DocScrutinizer05or ake it that big that nobody ever will move it away from terrace01:35
wpwrak2 kW should be enough for the PC and screens. that's what i'm aiming for. A/C is too far out.01:35
rohput it in a shack on the terrace01:35
DocScrutinizer05I'm also looking for a nice handy 2kW01:36
wpwrakDocScrutinizer05: don't forget the elements. these things are usually not designed for prolonged outdoors use01:36
wpwrakthe yamaha looks kinda nice. quiet, modern technology01:36
DocScrutinizer05meh, give it a plastic hood01:36
wpwraktank is a bit small01:36
wpwrakplastic + wind = no plastic :)01:37
rohwpwrak: or buy a big one and sell the power to the neighbours by the kwH01:39
wpwrakhehe :)01:40
DocScrutinizer05wtf is wrong with Europe or with yamaha? http://www.pfau-motorgeraete.de/Stromerzeuger/Stromerzeuger-EF2000iS-Yamaha--507.html01:51
DocScrutinizer051000$ vs 2000EUR01:52
DocScrutinizer05well 1700EUR01:52
DocScrutinizer05the Yamaha looks nice01:56
wpwraknice taxes. EUR 1700 looks actually more expensive than in argentina :)01:56
DocScrutinizer05well, a little searching made that more like 130002:07
whitequarkwpwrak: your air conditioners ?03:07
whitequarkhow many do you need03:08
wpwrakwhitequark: naw, i just want my pc to have power. i can survive without air conditioning. drink more water, take more showers :)03:20
wpwrakwell, pc, and if it's a really long blackout, also the fridge03:20
whitequarkspoken by a true geek03:24
whitequark"the beer must flow" ? :p03:24
wpwrakyeah :)03:26
wpwrakbeer is important. liquid carbohydrates. because, without power, it's 14 floors down to go shopping, then 14 floors up again03:27
whitequarkmaybe you could arrange a series of ropes and pulleys. a makeshift elevator.03:28
whitequarkand (unless you're suicidal) you would need an accomplice below03:29
wpwrakhmm, why do i have to think of this ? http://www.youtube.com/watch?v=HzAtimGNVsQ03:32
DocScrutinizer05God! watched 3 movies on youtube, now I feel nausea03:48
whitequark"doctor, if I press here, it hurts" "don't do that, then"03:53
larsc_quiet day17:10
larsc_must be holiday season17:16
wpwrakwell, DocScrutinizer05 is probably busy with neo900, whitequark should be in the middle of the customary pre-fueling sessions, apelete may be celebrating that m-usb works, a bunch of people may be busy preparing for CCC, ...17:17
whitequarkpre-fueling ?17:18
wpwrakthe process where you replace bodily water with low-grade vodka, to prepare for the serious stuff of the holidays17:26
Action: whitequark sighs17:28
wpwraksorry, russian stereotypes are just way too much fun to not make fun of them ;-)17:29
wpwrakapropos stereotypes, this is by far the best video on russian street life i've seen: http://www.youtube.com/watch?v=E-l4w-DIiXk17:45
whitequarkthank you for reminding me why I will never ever drive18:16
larsc_teleportation is so much cheaper anyway18:37
whitequarkpublic transport ?18:37
larsc_mass to energy conversion ;)18:39
larsc_matter of course18:40
wpwrakwhitequark: those folks seem to really enjoy driving :)18:41
whitequarkwpwrak: http://www.youtube.com/watch?v=Muv7Suqut0E18:44
larsc_they stayed quite calm18:46
whitequarkdialogue after the impact: "[expletive] awesome... [idiomatic expletive meaning "copulating cats"], [expletive]... we're swimming... wow, [expletive]... where are we swimming? to the shore, [expletive]. straight? to the shore. don't touch the steering wheel"18:52
whitequark([expletive] because it's impossible to translate while preserving the fine details of meaning)18:52
wpwrakkewl :) i love the coolness with which they react to all those accidents18:55
wpwrakzrafa: btw, are you having any luck with taking to the freescale chips ?20:49
zrafawpwrak: I have not started yet21:27
zrafawpwrak: we will try with a parallel port . But first we will do some tiny board to expose the pins as well21:28
wpwrakhmm, better use ben + ubb22:00
zrafawpwrak: I was thinking in that as well, tempted because the 3.3v from ubb :)22:16
zrafawpwrak: but we did not do much yet. Lot of bored stuff with students now at the end of the year :(22:16
zrafa(papers, forms, exams)22:16
nickoewpwrak: meh, I have forgot how to use fped again...22:45
nickoeI can't make it make a pad without failing22:46
nickoeTrying to make a pad from vec __0 and __1 does not work22:49
wpwraknickoe: that's because you have a loop23:01
nickoemmm, on those?23:02
wpwraknickoe: the loop repeats everything in its frame, including the pads23:02
nickoealso when it does not use the loop, m?23:02
nickoeso I just need  to creat another fram with the loop 23:03
wpwrakyes, that will work23:03
nickoewpwrak: mmm, does not even work like this, http://folk.ntnu.no/nicko/moar_stuff/circularthing2.fpd23:07
nickoeif it ever uploads23:09
wpwrakyour loop is still in the root frame23:26
wpwrakso fped repeats the root frame (and everything below)23:26
