rohDocScrutinizer05: hm. nothing matches... well.. back to the seller it goes03:25
xiangfuDocScrutinizer05: Hi, is the case ok for you? what should we do on the cases?03:25
DocScrutinizer05xiangfu: sorry, still stuck at customs03:32
DocScrutinizer05so I can't say anything more than a few weeks ago03:33
xiangfuDocScrutinizer05: ok.03:33
xiangfuis there anything I can help?03:33
DocScrutinizer05well, probably not03:34
xiangfuok.03:34
xiangfulet me know anything I can help.03:34
DocScrutinizer05there been one tiny typo in invoice but that doesn't explain how customs cocks up03:34
DocScrutinizer05I sent them a lengthy explanation of what's the content and where to look on ebay for faintly similar objects and their value03:35
DocScrutinizer05thios been a few days ago, I hope it will finally go free now03:36
DocScrutinizer05xiangfu: I'll ping you as soon as I know any news03:37
xiangfuOkey03:38
DocScrutinizer05maybe eventually I'll have to tell customs to contact you and tell them that you dug out those cases from your garbage bin03:38
DocScrutinizer05but I doubt they would even bother to contact you, after all you can tell then no more than you already did in invoice. Or anything you like03:40
DocScrutinizer05when they don't trust ebay, they will probably need to have some expert check the parcel's content03:41
DocScrutinizer05jerks03:41
DocScrutinizer05too many parcels from china, all declared as "gift" or otherwise fraudulent03:42
DocScrutinizer05german customs gets pissed since years03:42
xiangfuyes.03:46
DocScrutinizer05next time we add more google searchterms to the content declaration03:48
DocScrutinizer05are the cases re-assembled or in separate parts?03:49
DocScrutinizer05IOW can customs dude see that there's missing the PCB?03:50
DocScrutinizer05well, he probably could anyway when sliding open, there's abig hole where kbd should be ;-D03:50
xiangfuin separate parts.03:55
xiangfubut I put them together. for don't break when shipping.03:55
DocScrutinizer05thanks!03:58
DocScrutinizer05:-)03:58

wpwrakaah, finally ! (in german) http://www.heise.de/newsticker/meldung/Nassrasierer-bestellt-auf-Knopfdruck-neue-Klingen-2580253.html11:35
wpwraktaking care of all the intricate logistics of buying and stockpiling new blades has really been intolerable11:36
eintopfinternet of things are there12:06

arossdotme#got a 2.5 inch 12v +/- composite lcd but it's got a darn clf backlight. so it's a noise monster and needs 300ma ! when my 4.3 inch one with led backlight uses 100ma @12. i want to run it rom a little lithium batt. i see the clf is held sandwiched on top via some screw, could i replace it easily with a led one if so any quick suggestions?16:54
arossdotme@12v16:55
arossdotmethis screen has a built in lift/right flip which means i can use it for taking selfys with my action camera16:56
arossdotmewhich no other screen has16:56
arossdotmeor at lest small screen16:56
DocScrutinizer052.5" CFL :-o18:18
DocScrutinizer05dang that thing must be old18:18
DocScrutinizer05"White LEDs? You're kidding!" ;-P18:18
DocScrutinizer05generally replacing backlight by another technology or design is *very* difficult18:19
DocScrutinizer05ideally check out where the CFL sits and replace the CFL by a LED strip, with no more than 5mm pitch between LEDs18:20
DocScrutinizer05then you 'just' need to figure which direction the LEDs have to face to - mind you a CFL is omnidirectional by design18:21
DocScrutinizer05odds are your efficiency of new design is so poor that you need even _more_ power for the LEDs than for the CFL18:22
DocScrutinizer05what do you mean by "noise monster"?18:22
DocScrutinizer05EMI? or audio?18:23
DocScrutinizer05if you meant audio, then there#s sth defect in the converter, which might allso account for the high power consumption18:23
DocScrutinizer05prolly the whole thing is sooooo oooold that the elcos fell dry meanwhile. Nothing unusual, and would well cause audible noise and poor efficiency18:25
DocScrutinizer05also cheap crappy inductors/transformers/chokes can cause quite some audible noise and same time reduce efficiency18:27
DocScrutinizer05impact on efficiency isn't _that_ much though in this case18:27
DocScrutinizer05unless the thing gets saturated18:27
DocScrutinizer05(= operating at too high current)18:28
DocScrutinizer05then efficiency drops through the ground18:28
DocScrutinizer05like: 200 of the 300mA would simply heat up the choke then18:29
DocScrutinizer05decent SPSU have a controller that avoids such pathological states of operation. Simple cheap ones you can bet will suffer from exactly that on overload of output18:31
DocScrutinizer05wpwrak: LOL18:37
Action: DocScrutinizer05 waits until Braun offers a beard shaver that works automatically, after asking with friendly voice "do you want a shave now, Sir?" (the variant with s/Sir/Madam/ will prolly not make it to market)18:40
DocScrutinizer05Ms Wurst uttered disappointment18:41
Action: DocScrutinizer05 still waits for toilet paper with a e-ink watch in every sheet18:42
arossdotmeD ocScrutinizer umm i there i heard a little bit of noise but whats bad is it has a built in speaker but the noise the audio circuit picks up is awful. it's louder then the audio output from my camera 18:42
arossdotmei was suprised to see it uses clf18:43
DocScrutinizer05pph, that clearly indicated eelctrolytic capacitors gone south, no?18:43
DocScrutinizer05ooh*18:43
arossdotmeguess thats why it has analog brightness,sat18:44
arossdotmenobes18:44

arossdotmebtw know of such a thing as a composite limage flip? that mirror flips the image?18:48
arossdotmeso i can use the average little lcd as a selfy external monitor18:49
arossdotmeso you unput rac video and you get a rac composite output18:49
arossdotmeunput=input18:49
arossdotmei guess i just have to use a bigger batt pack and lithim batt stetup conterver18:50
arossdotmeso much for a small light what screen for my tiny action cam18:51
arossdotmewhat =weight18:51
arossdotmemore of the smae lcd but for sale http://www.aliexpress.com/wholesale?shipCountry=uk&shipFromCountry=&shipCompanies=&SearchText=2.5&exception=&minPrice=&maxPrice=&minQuantity=&maxQuantity=&isFreeShip=n&isFavorite=n&isRtl=n&isOnSale=n&isBigSale=n&similar_style=n&similar_style_id=&isAtmOnline=n&CatId=20000380718:53
Action: DocScrutinizer05 waits for xiangfu to show up23:55
DocScrutinizer05dang, I removed HK from my worldclock23:56
DocScrutinizer05hmm, almost 8 AM23:57
DocScrutinizer05:-)23:57
