| Guest24069 | cladamw: hi good morning! | 01:31 |
|---|---|---|
| Guest24069 | oops, my nick again... | 01:31 |
| wolfspra1l | I have a board with a soldered cable connection that is a little unstable | 01:32 |
| wolfspra1l | so to protect that connection, I want to just put some hot glue around it | 01:33 |
| wolfspra1l | what is that 'hot glue' exactly? | 01:33 |
| wolfspra1l | is it just heated silicone? | 01:33 |
| wolfspra1l | what brand/type do you use? | 01:33 |
| kristianpaul | heated silicon yes | 01:40 |
| kristianpaul | but froma gun | 01:40 |
| kristianpaul | brand.. well i choose cheaper around :) | 01:40 |
| kristianpaul | morning there btw :) | 01:40 |
| wolfspra1l | thanks, good morning/evenint! :-) | 01:41 |
| wolfspra1l | evening | 01:41 |
| kristianpaul | 20:42 here yes evening :) | 01:42 |
| kristianpaul | he i would said my silicone hot gun/glue is near 15 years old ;) | 01:43 |
| cladamw | wolfspra1l, good morning ! | 01:44 |
| cladamw | wolfspra1l, silicone glue -> you can let it naturally dried by normal room temperature through silicone. | 01:46 |
| cladamw | (hot glue) to glue the place with parts or somewhere that by heated air, but also can be naturally dried for gluing. | 01:48 |
| cladamw | for example, there's 'hot glue' between the Microphone and pcb surface in M1R3. It's a flat thin hot glue. you can watch it. ;-) | 01:49 |
| wolfspra1l | hot glue != silicone? | 01:50 |
| cladamw | that hot glue is not my silicone glue tool. M1 is done by smt factory. | 01:50 |
| cladamw | no, not silicone. | 01:51 |
| wolfspra1l | can you describe exactly what brands/material you use? | 01:51 |
| cladamw | my home tool is silicone one. ;-) | 01:51 |
| wolfspra1l | and you heat that silicone? | 01:51 |
| wolfspra1l | or use at room temperature? | 01:51 |
| cladamw | let me google for example to you. | 01:51 |
| wolfspra1l | xiangfu: good morning! | 01:52 |
| wolfspra1l | everybody back :-) | 01:52 |
| xiangfu | good morning | 01:53 |
| zenlunatic | hello all | 01:53 |
| cladamw | wolfspra1l, http://detail.china.alibaba.com/buyer/offerdetail/128650606.html | 01:58 |
| cladamw | brand: MAXBOND, p/n: 1603HFR-HS, sorry it's in Chinese. checking in english more ....wait ;-) | 01:59 |
| cladamw | temperature: 120 degree. | 01:59 |
| wolfspra1l | so it heats the regular silicone to 120 celsius? | 02:01 |
| cladamw | just 120 celsius can let it dry. ;-) | 02:02 |
| cladamw | http://www.google.com.tw/url?sa=t&rct=j&q=1603HFR-HS+MAXBOND&source=web&cd=5&ved=0CEkQFjAE&url=http%3A%2F%2Fwww.dongbufinechem.com%2Fmodule%2Fdownload.asp%3Fdowntype%3Dmaxbond_product%26productcode%3DM-15867635%26filenamec%3D1603HFR-HS_E.pdf%26filenames%3D3765953862264639&ei=LzVMT_yCLYvEmQXSw73_Dw&usg=AFQjCNE-0NsCLkrxzMoOROCyPXDNAOiGZA&cad=rja | 02:02 |
| wolfspra1l | ah I see [first link], that's the "hot glue" itself | 02:02 |
| wolfspra1l | it would be better to find the right chemical name, then we have a nice link into wikipedia :-) | 02:02 |
| cladamw | smt factory use likely this element but may different brand though. | 02:03 |
| cladamw | oah..yeah...need check in wikipedia. ;-) | 02:03 |
| wpwrak | wikipedia says it's usually a polymer. though it lists a gazillion of chemicals that can be used. so it's probably best to think of it as a kind of thermoplastic. | 02:04 |
| cladamw | http://en.wikipedia.org/wiki/Chloroprene this ? | 02:07 |
| wpwrak | i was thinking of http://en.wikipedia.org/wiki/Hot_glue#Materials_used | 02:09 |
| wpwrak | no idea about chloroprene ;-) | 02:10 |
| cladamw | wolfspra1l, you can just buy it some similar in China http://item.taobao.com/item.htm?id=10820986069 | 02:14 |
| cladamw | for small use. not as industry purpose. ;-) http://item.taobao.com/item.htm?id=9719438742 | 02:15 |
| cladamw | hope this helps you. :-) | 02:15 |
| wolfspra1l | oh that's just a tube with some glue inside that you can push out like a cream, at room temperature? | 02:17 |
| wolfspra1l | (first link) | 02:17 |
| wolfspra1l | for documentation purposes - what's the chemical there? | 02:17 |
| wolfspra1l | ah it says there, chloroprene rubber | 02:17 |
| wolfspra1l | drying time 2-4 minutes | 02:18 |
| wpwrak | both look like regular glue. the most common hot glue comes in the form of cylindrical sticks. you then heat it with a hot glue gun, i which it liquifies. you then push it out to make the bond. | 02:18 |
| cladamw | wolfspra1l, yes, this http://item.taobao.com/item.htm?id=10820986069 you can let it dried under 2^4 minutes only at room temperature. no need heat air. | 02:18 |
| wolfspra1l | why does it say "temperature 120 celsius"? that means it must be heated to 120 celsius before/when being applied? | 02:19 |
| wpwrak | one gotcha: the cheap guns overheat and then fail. | 02:19 |
| cladamw | 120 celsius is its rating temperature not heated air to let it dry. ;-) | 02:19 |
| wolfspra1l | ah so it must not get hotter than 120 celsius? | 02:19 |
| cladamw | wolfspra1l, correct. no more than 120 | 02:20 |
| cladamw | just use room temperature. | 02:20 |
| wolfspra1l | if it can be applied at room temperature - no heatup/gun needed? | 02:20 |
| wolfspra1l | ok, cool | 02:20 |
| wolfspra1l | (literally :-)) | 02:20 |
| cladamw | good luck | 02:20 |
| wolfspra1l | always | 02:20 |
| wolfspra1l | avanti dilettanti | 02:20 |
| wolfspra1l | I see how Chinese work, successfully, I can do brain surgery tomorrow | 02:21 |
| wolfspra1l | just need to find a patient | 02:21 |
| wolfspra1l | but after a few thousand, I should be pretty good | 02:21 |
| cladamw | ;-) | 02:21 |
| wolfspra1l | yeah. learnt something here :-) | 02:21 |
| wolfspra1l | the secrets :-) | 02:21 |
| wolfspra1l | cladamw: thanks, I think that's clear now. | 02:21 |
| wolfspra1l | cloropene rubber, room temperature, 2-4min drying time | 02:22 |
| cladamw | yes, you got it. ;-) | 02:22 |
| wpwrak | at patient 1001, you may still have no idea what to do, but you'll have a very long list of things you absolutely have to avoid ;-) | 02:22 |
| xiangfu | wpwrak, :-) | 02:22 |
| wolfspra1l | wait let's get at least the spelling right | 02:23 |
| wolfspra1l | nasty German habits. chloroprene rubber. | 02:23 |
| wolfspra1l | :-) | 02:23 |
| wpwrak | in most such cases, i simply use superglue :) | 02:25 |
| wolfspra1l | can all glues assumed to be non-conductive? | 02:25 |
| wpwrak | unless they advertise them as conductive ... :) | 02:26 |
| cladamw | wpwrak, me too. i even used 3M glue. ;-) to buy that taobao is not bad. | 02:26 |
| wpwrak | silicone is also good for gluing. but it's a bit flexible, which may be an issue in that case | 02:27 |
| wpwrak | i mainly use it to keep things in place, but not to resist major mechanical stress | 02:27 |
| wpwrak | (silicone) "household" silicone glue | 02:28 |
| wpwrak | wolfspra1l: if there are things like a DIY supermarket in china, you may want to visit their section of glues. you should be able to identify a dozen distinct types. a lot of them will serve you well. | 02:29 |
| wpwrak | many of the universal glues are rigid but not too brittle. | 02:30 |
| wolfspra1l | every market is a DIY supermarket in China | 02:30 |
| wpwrak | and then you get some for special purposes. like stuff that cures in water. | 02:30 |
| wpwrak | ;-) | 02:30 |
| wolfspra1l | but I want to keep it simple, already learnt now | 02:30 |
| wolfspra1l | by default we can think of any glue as non-conductive | 02:31 |
| wpwrak | simple = you go to the shop down the street and pick up what you want | 02:31 |
| wolfspra1l | regular household silicone is quite flexible even after dried | 02:31 |
| wpwrak | not simple = collect opinions from people around the world, including the world's largest encyclopedia ;-) | 02:31 |
| wolfspra1l | I think me (or anyone) can easily find that chloroprene rubber though | 02:31 |
| wpwrak | (silicone) yes. it's good for coating or for attaching things. but it's not good for resisting major forces. | 02:32 |
| wpwrak | anything acrylic should be much better than silicone for rigidness | 02:33 |
| wpwrak | not sure about *prene | 02:34 |
| wolfspra1l | cladamw: how hard will the chloroprene rubber be after drying? | 02:34 |
| wolfspra1l | some of those 'hot glues' tend to become very hard | 02:34 |
| cladamw | chloroprene rubber is harder than home silicon glue. | 02:36 |
| cladamw | you can try to bend Microphone in M1R3. ;-) not like soft home silicon after dried. ;-) | 02:36 |
| cladamw | i don't know what exact target(board or cable) you'd like to glue though. ;-) | 02:38 |
| wolfspra1l | I just have a fpc cable that ends in a soldered connection | 02:41 |
| wolfspra1l | and I'm worried that the solder joints will break, there is too much mechanical bending back and forth happening | 02:41 |
| wolfspra1l | so I want to seal that whole soldered connection under/in a stiff strip of glue | 02:42 |
| wolfspra1l | then the mechanical movement goes into the fpc only, but the solder joints are fixed | 02:42 |
| wpwrak | superglue under the fpc between making landfall and the solder joints ? or is that area too small ? | 02:45 |
| wpwrak | before superglueing, clean and dehydrate with alcohol, then let it dry for a bit | 02:45 |
| wolfspra1l | wpwrak: sure I can try superglue | 03:26 |
| wolfspra1l | in fact the fpc arrives at the pcb in a very steep angle, and the solder joints are bent backwards (in the direction the fpc came from). so yes, maybe I just superglue under and above the fpc | 03:27 |
| xiangfu | http://downloads.qi-hardware.com/software/images/Milkymist_One/2012-02-26/ :) | 04:22 |
| xiangfu | I think I will move my tested images to there ^^ | 04:22 |
| xiangfu | remove the snapshot from reflash_m1.sh | 04:25 |
| xiangfu | rename --snapshot to --qi maybe ? | 04:25 |
| zenlunatic | you guys use a case for your ben? | 04:26 |
| xiangfu | or keep the --snapshot just add a new one "--qi" | 04:26 |
| xiangfu | zenlunatic, music. :) | 04:26 |
| xiangfu | someone make a QT version usbboot for jz4760: http://gforge.ictp.it/gf/project/xburst-tools/wiki/?pagename=QTUSBBoot | 07:31 |
| xiangfu | http://en.qi-hardware.com/wiki/Milkymist_One_Firmware#2012-02-26 | 07:33 |
| Action: xiangfu release a Milkymist One, Qi Image: http://downloads.qi-hardware.com/software/images/Milkymist_One/2012-02-26/ :) | 07:53 | |
| xiangfu | try that by 'reflash_m1.sh --qi' | 07:53 |
| xiangfu | tested by : http://en.qi-hardware.com/wiki/Milkymist_One_Firmware#Test_Plan | 07:53 |
| wpwrak | xiangfu: hmm, i wouldn't say "Support rendering multi-image files". that can be misunderstood as referring to a feature we don't have yet. how about "Support multiple image files" ? | 08:06 |
| wpwrak | and what's "A set of host cool from Werner on compiling patch and FPVM lib" ? :) | 08:07 |
| wpwrak | even if i s/cool/tools/ i don't understand it ;-) | 08:07 |
| xiangfu | just your new script files. under flickernoise/compile/... and fpvm lib folder. | 08:07 |
| xiangfu | I didn't look the detail. | 08:07 |
| xiangfu | for test compile patch ? | 08:08 |
| wpwrak | oh. you mean idgen and file2h ? well, they're just part of the now more complex build process | 08:08 |
| xiangfu | what about the src/compiler/test/ ? | 08:09 |
| xiangfu | and ptest? | 08:10 |
| xiangfu | I never tried them :( | 08:10 |
| wpwrak | these are regression tests | 08:11 |
| wpwrak | not user-visible features :) | 08:11 |
| wpwrak | ptest can be used to test patches on the PC, though | 08:11 |
| wpwrak | but that need some wrapping. it's a bit quirky to invoke from the command line. | 08:12 |
| xiangfu | wpwrak, maybe move that to last line like "new regression tests tools for patch language" ? | 08:13 |
| wpwrak | dunno. it's something quite internal. kinda hard to explain for non-developers | 08:14 |
| xiangfu | wpwrak, "new regression tests tools for patch language for developer" | 08:18 |
| wpwrak | heh ;-) | 08:19 |
| wpwrak | wolfgang: fun with the firewall ? :) | 08:41 |
| DocScrutinizer51 | moo | 10:14 |
| whitequark | moo? | 10:16 |
| DocScrutinizer51 | moo does the cow | 10:17 |
| DocScrutinizer51 | and I say moo for 'morn' | 10:18 |
| whitequark | ah, that explains everything | 10:45 |
| hjbjh | hi can any tell where can i find 2 track sound in the web | 11:10 |
| whitequark | fucking samsung. | 13:05 |
| whitequark | http://i.stack.imgur.com/2pboa.jpg | 13:06 |
| whitequark | no wonder 6gbps mode fails. it's a bit strange that 3gbps mode still works. | 13:06 |
| whitequark | I confirmed that if I straight the cable up, the rate of errors decreases significantly on the same workload. | 13:07 |
| whitequark | (also, in the process I almost broke the cable finally. damn.) | 13:07 |
| whitequark | moral of the story: think before you do [high-speed connections]. not the other way around. | 13:07 |
| DocScrutinizer51 | heh | 13:54 |
| DocScrutinizer51 | tickets against MIPI-HSI, my daily headache. Though our hw is fine, just has no transmission secure layer so everybody pointing at HSI no matter what's the real root cause ;-P | 13:55 |
| rz2k | hey whitequark | 14:04 |
| rz2k | last part of my package arrived | 14:04 |
| rz2k | wanna meet on saturday? | 14:05 |
| kristianpaul | DocScrutinizer51: it supose to asume "security" is no implemenented on transport layers.. | 14:10 |
| kristianpaul | thats a task for the aplication to choose and encryption method and not relay in lower layers.. | 14:11 |
| whitequark | rz2k: yeah, possible | 14:38 |
| whitequark | I've already fetched it | 14:38 |
| whitequark | surprisingly, I have not screwed up my latest board | 15:00 |
| whitequark | http://i.imgur.com/BUhfA.jpg | 15:00 |
| DocScrutinizer51 | kristianpaul: sure, though I'm talking about simple checksum/patiry things here | 15:30 |
| DocScrutinizer51 | error correction | 15:31 |
| DocScrutinizer51 | HSI is basicaly unidir | 15:31 |
| DocScrutinizer51 | so no matter if wrong stopbit or defect RAM, the dat* at RX side is corrupt, everybody points at HSI driver | 15:35 |
| DocScrutinizer51 | parity, not patiry | 15:36 |
| whitequark | my crappy skills... http://i.imgur.com/FVKt3.jpg | 16:03 |
