| wpwrak | cladamw: how is the pipeline going ? want more reviews ? or shall i give it a rest for today ? | 02:09 |
|---|---|---|
| cladamwa | wpwrak, ha~ me or you a rest. :-) well nice replies. | 02:11 |
| cladamwa | since your draft is old one. :-) | 02:12 |
| cladamwa | http://downloads.qi-hardware.com/hardware/milkymist_one/sch/tmp/MILKYMISTONE.pdf | 02:13 |
| wpwrak | ah nice, thanks ! | 02:14 |
| cladamwa | J24 in 2012/3/9 is already NC in pin 9 and 10. ;-) | 02:15 |
| wpwrak | yeah, saw it. everything already solved :) | 02:15 |
| cladamwa | but sorry i didn't inform you in advance. :-) | 02:15 |
| cladamwa | wait..but these two days of your replies I've not applied into new draft. so I'll try to update latest. :-) | 02:16 |
| wpwrak | well, it didn't all too long to explore the configuration space. finding the keyed header, on the other hand ... :) | 02:16 |
| wpwrak | s/didn't/didn't take/ | 02:17 |
| cladamwa | one thing i still don't know: what difference between yours and mine ? http://search.digikey.com/us/en/products/TSW-105-26-H-D-009/TSW-105-26-H-D-009-ND/2685930 | 02:18 |
| wpwrak | yours has 10 pins. mine only 9 :) | 02:20 |
| roh | wpwrak: about deg C/W vs K/W ... its not linear over all absolute ranges since its a semiconductor... and the package also has varying thermal resistance depending on absolute temp | 02:23 |
| cladamwa | decoding p/n naming system is hard to me...checking. | 02:23 |
| roh | wpwrak: atleast thats what i came up when thinking about it | 02:23 |
| wpwrak | roh: sure. but you get that with celsius or with kelvin. it's ratios anyway. | 02:27 |
| wpwrak | cladamw: yes, the numbering schemes for these connectors is plain evil. and it seems that electromechanical engineers train for years until they master writing the most cryptic data sheets. | 02:29 |
| cladamwa | wpwrak, oh~ great ! yours has keying on pin 9 (-009) to be omitted, but both ours are no stock. :) | 02:37 |
| wpwrak | yes, but they can get it in one week. that's not so bad. | 02:38 |
| cladamwa | how do you know is one week? where link in digi-key i can see ? In Mouser I know, in Digikey I don't know. | 02:40 |
| wpwrak | "Quantity Available" has an input field. enter how many you want. then it tells you how long it'll take. | 02:41 |
| cladamwa | now i know how you sorting a 9 keying pins out. >> one parameter: "Number of Positions Loaded" phew~ | 02:42 |
| wpwrak | ah, now it's two weeks. seems that we just missed a deadline some hours ago. | 02:42 |
| wpwrak | yup :) | 02:43 |
| wpwrak | and then decrypt the datasheets of the ~20 matches | 02:43 |
| cladamwa | oh...yes, 3/29 comes out. :-) thanks telling me. :-) | 02:44 |
| cladamwa | another thing is that we don't know how a extension cable for USB-A looks like. | 02:44 |
| cladamwa | so Mating Length now we suppose it's a 5.84mm high. | 02:45 |
| wpwrak | yea, that's about the most common length. if it's a bit too long, that doesn't really matter. | 02:49 |
| wpwrak | and yes, we should think about how to actually use this. this will determine placement and orientation. | 02:49 |
| wpwrak | it seems at that wolfgang had some ideas. | 02:49 |
| wpwrak | maybe he's even got a bag of adapter cables hidden somewhere :) | 02:50 |
| wpwrak | there are two issues: 1) what kind of adapter(s) do we want to support, and 2) how do they mechanically attach to things | 02:51 |
| wpwrak | the easiest would be a little header-to-USB A PCB. these are commercially available but i don't know how well they'd fit. we could also make our own. | 02:52 |
| cladamwa | okay, so hope 5.84mm is okay. yes, your two issues came out is about to how i tell house to placement what place it would be. | 02:52 |
| wpwrak | wolfspra1l: do you envision M1r4 shipping with a means to put the dongle of the beautiful new RF keyboard _inside_ the M1r4 ? | 02:52 |
| wpwrak | just checked my stash of headers. 230 mil is perfect. | 02:54 |
| cladamwa | umm... 230 mil = 5.84mm, so is it a cable like USB yours ? | 02:57 |
| wolfspra1l | wpwrak: I haven't thought about it yet | 02:57 |
| wpwrak | cladamw: ah, i didn't try the USB cable. lemme see ... | 02:57 |
| wpwrak | cladamw: yes, the cable is very happy with 230 mil, too | 02:59 |
| cladamwa | great ! so yours is the one for PC front panel usb daugher board alike ? | 03:00 |
| cladamwa | if yes, means the pdf we found from intel is surely settled for industry field though. :-) | 03:01 |
| wpwrak | mine is for a PC slot. didn't feel like taking a PC apart :) | 03:01 |
| cladamwa | also great ! :) | 03:02 |
| cladamwa | wpwrak, I'll take a look that such USB-cable in PC from my brother. then we know how usb cable's connection itself on shields and signal ground. | 03:29 |
| wpwrak | in the case of my cable. USB GND also connect to shield | 03:59 |
| wpwrak | s/connect/connects/ | 04:00 |
| cladamw | wpwrak, one question - I updated *.csv file and i put original J24's FCi p/n in to "SUBSTITUTION P/N" and "SUBSTITUTION LINK", then fill yours in "MANUFACTURER P/N" and "DATASHEET LINK", after i 'make' then dsv J24, it still shows the older one FCi link ? | 04:03 |
| wpwrak | hmm. did it download the new data sheet ? | 04:07 |
| cladamw | no | 04:09 |
| cladamw | seems your script detect if /.dsv has 'dsv-J24' firstly then ignore ? | 04:10 |
| wpwrak | strange. no, it should handle this properly | 04:10 |
| cladamw | well, just fyi. :-) | 04:10 |
| cladamw | ah ? | 04:11 |
| wpwrak | does BOOKSHELF have the right URL ? | 04:11 |
| cladamw | but i checked .csv filled very well without newlines though. and no Error 1 after 'make' | 04:11 |
| cladamw | hmmm..checking.. | 04:12 |
| cladamw | good, it's there. :-0 | 04:13 |
| cladamw | # Conn Unshrouded Header HDR 10 POS 2.54mm .100 | 04:13 |
| cladamw | N: http://www.samtec.com/ftppub/cpdf/TSW-MK.PDF | 04:13 |
| cladamw | A: J24 | 04:13 |
| cladamw | D: http://portal.fciconnect.com/Comergent/fci/drawing/69192.pdf | 04:13 |
| cladamw | but typed "dsv J24", it shows old pdf. :( | 04:13 |
| wpwrak | so that's not right. N is the part name | 04:14 |
| wpwrak | and D is the URL | 04:14 |
| cladamw | ah ? | 04:14 |
| cladamw | sorry that my fault ? | 04:14 |
| wpwrak | maybe :) | 04:15 |
| cladamw | ah ~ excuse me ! My fault !!! :-O now works. | 04:16 |
| wpwrak | whee ! ;-) | 04:17 |
| wpwrak | you had me scared for a moment. a bug in my script ? unthinkable :) | 04:17 |
| cladamw | hehehe...sorry that I should have not doubted your script ! Adam is stupid. :-O | 04:20 |
| azonenberg | Anybody know how many layers the MM1 board is? | 05:03 |
| wolfspra1l | azonenberg: 6 | 06:04 |
| wolfspra1l | just ran into this http://intrl.startech.com/Cables/USB-2.0/Internal-and-Panel-Mount/2-USB-A-Female-to-Motherboard-Header-Adapter~USBMBADAPT2 | 06:04 |
| wolfspra1l | the photo gallery shows a keying in the 3rd pic | 06:04 |
| azonenberg | wolfspra1l: ok, thought so | 06:04 |
| azonenberg | 'm trying to build a spartan6 board (FTG256) on 4 layers and its hard | 06:04 |
| wolfspra1l | so I guess the R4 internal USB would be compatible with this? (unfortunately I couldn't find a datasheet for that part right away) | 06:04 |
| cladamw | wolfspra1l, the startech you gave has : http://intrl.startech.com/media/products/USBMBADAPT2/PDFs/USBMBADAPT2.pdf | 07:41 |
| cladamw | their pitch looks very much like 2.54mm though. | 07:42 |
| Artyom | Hello everyone. I want to ask one question. There will be a conference in the university about "open technolugies in engineering" (http://oskonf2012.bmstu.ru/ google translate: http://translate.google.com/translate?sl=ru&tl=en&js=n&prev=_t&hl=en&ie=UTF-8&layout=2&eotf=1&u=http%3A%2F%2Foskonf2012.bmstu.ru%2F&act=url ). I can prepare a thesis about "MM SoC + namuru" for building a GNSS... | 08:38 |
| Artyom | ...receiver. What do you think about it? | 08:38 |
| wolfspra1l | Artyom: great! :-) | 08:46 |
| wolfspra1l | who attends? would a topic of Milkymist + namuru be good for them? | 08:47 |
| Artyom | Good question. I think that open-hardware is not very popular here because most people don't know about it. I don't know any details about this conference, because it is the first time it will be hold. | 08:51 |
| Artyom | I know that the person that will talk about KiCAD is rather famous among russian KiCAD useres because he makes localized versions and improves it. | 08:52 |
| Artyom | My first idea was to tell about about scilab glonass-receiver. But MM SoC + namuru fits this conference too. | 08:53 |
| wolfspra1l | Artyom: yes sounds like it could be a fit, especially since we do so much KiCad work as well, and the Milkymist One will definitely start moving to KiCad as well | 09:24 |
| Artyom | ok, I will write them e-mail with my offers and see what will be their reaction ;) | 09:36 |
| lekernel_ | should it still be called M1 then? | 09:44 |

| wolfspra1l | lekernel: what do you propose? | 10:08 |
| wolfspra1l | I wouldn't rename anything at this point, since we have minimal traction and any renaming adds confusion | 10:08 |
| wolfspra1l | maybe just drop the 'One' at some point? :-) | 10:09 |
| wolfspra1l | I wouldn't touch anything | 10:09 |
| lekernel | today A MIRACLE HAPPENED: I received the Warsaw videos. | 11:25 |
| lekernel | wolfspra1l: no idea yet, would have to think about it ... | 11:30 |
| lekernel | ah, sound codec problems now... but the pictures are much better than on the first videos | 11:36 |
| wolfspra1l | lekernel: don't think about it, leave everything as-is | 12:48 |
| wolfspra1l | the last thing you need are any new names | 12:48 |
| wolfspra1l | we need the milkymist brand to be talked about and reitereated over and over | 12:48 |
| wolfspra1l | even the distinction between milkymist and milkymist one doesn't matter in that context | 12:49 |
| lekernel | grmbl... scratched DVDs | 12:50 |
| lekernel | next step: data forensics | 12:50 |
| lekernel | it'll never end | 12:50 |
| lekernel | do such machines work? http://www.amazon.com/Simotech-DSR-1-DVD-Repair-Machine/dp/B000GX31G6 | 12:56 |
| sh4rm4 | lekernel, i'd rather try on another dvd drive | 13:05 |
| lekernel | there are clear scratches on the disc surface | 13:05 |
| lekernel | and the discs without scratches are readable... | 13:05 |
| sh4rm4 | still, some drives do a lousy job at error handling | 13:06 |
| lekernel | (but of course, it's a muli-part RAR archive split on three DVDs ...) | 13:06 |
| sh4rm4 | especially samsung drives seem to suck, while sony optiarc(NEC) seems to do well | 13:07 |
| lekernel | it's an optiarc drive :) | 13:07 |
| sh4rm4 | but probably a notebook drive | 13:09 |
| sh4rm4 | c't magazine tested one of those repair kits once, and the results were not so bad | 13:09 |
| sh4rm4 | although that was a much cheaper model | 13:09 |
| kristianpaul | Artyom, fantastic ! | 14:35 |
