DocScrutinizer51magnetometer for 12mm² cable amperemeter00:02
wpwrakhmmm :)00:31
wolfspraulit looks like CERN is sponsoring some KiCad work?01:26
wolfspraulin the flood of mails I may have identified something like that, need to check a little whether it's a meaningful contribution, but it sounds like01:26
qi-botThe build was successfull, see images here: http://fidelio.qi-hardware.com/~xiangfu/compile-log/openwrt-xburst.full_system-09282011-2207/02:13
rejonwolfspraul, is that spectec wifi chip working on latest builds of nn image?03:13
rejonxiangfu is where?03:13
wolfspraulrejon: I doubt it's working out of the box03:20
wolfspraulxiangfu is traveling over the chinese holidays, online once in a while03:20
rejonok03:21
rejonwolfspraul, did you get any more ben-wpan?03:22
wolfspraulnot yet03:22
wolfspraulgood point, have to order more from tuxbrain :-)03:22
wpwrakregarding CERN: https://lists.launchpad.net/kicad-developers/msg06976.html03:42
kristianpaulvery  interesting threads in cern mail lists http://lists.ohwr.org/sympa/arc/oh-workshop-2011/2011-09/msg00004.html 04:34
wpwrakgrmbl. X crash :-(05:25
wpwrakwolfspraul: did you see ? <wpwrak> regarding CERN: https://lists.launchpad.net/kicad-developers/msg06976.html05:48
wpwrakand i think our next project should be a communication satellite for wolfgang :)05:48
wolfspraulI saw that mail but I thought it was a little light on details05:50
wolfspraulbut maybe that is all for now05:50
wpwrakyeah, that's all i saw about it for now about putting resources into it. there's a bit more technical stuff on the cern side.05:53
wpwrakhere, a bit hidden in "phase II" of the list here: http://www.ohwr.org/projects/ohr-meta/wiki/Foss-pcb06:12
qi-bot[commit] Werner Almesberger: labsw/: redesigned rear connections to pair in/out by "near" potential (master) http://qi-hw.com/p/wernermisc/9ffb0c806:12
qi-bot[commit] Werner Almesberger: labsw/: re-layout for the various design changes (including potential separation) (master) http://qi-hw.com/p/wernermisc/7bc6c8906:12
qi-bot[commit] Werner Almesberger: labsw/: added partially populated DIP6 sockets since DIP4 is hard to source (master) http://qi-hw.com/p/wernermisc/162db3809:55
qi-bot[commit] Werner Almesberger: labsw/labsw.brd: tightened some traces (master) http://qi-hw.com/p/wernermisc/a124f1b09:55
DocScrutinizer2haha, now I see how wpwrak could dig out those weird "green" sockets10:11
DocScrutinizer2wpwrak: don't forget by any chance to insert dummy wire stubs into the 2 unused pins of the DIP610:13
DocScrutinizer2or acrylic glue10:13
DocScrutinizer2dang10:13
DocScrutinizerwpwrak: you don't want to get confused and occasionally insert the chip one position off10:15
DocScrutinizerDIP4 ? Hell, yeah, never seen...10:17
roh  11:28
wpwrakDocScrutinizer: if you mis-insert, nothing bad will happen (except the circuit not operating, of course)12:45
DocScrutinizeraaah, of course12:46
wpwrakDocScrutinizer: it's for the opto-couplers. i use small ones in DIP4. i pair most of them in DIP8, but there's one pair i can't put next to each other (due to possible difference in potential) 12:47
DocScrutinizeranyway blocking the unused contacts with a "plug" is a nice thing to do12:47
DocScrutinizer(optocouplers) gathered as much12:48
wpwrakdo you know of such a "plug" ? i know this sort of thing for 100 mil heades (little plastic cones) but i've never seen anything like this for DIP12:49
DocScrutinizerwell, for mass production you probably would want to use single contacts. For small series you as well could cut away the excessive contacts from a socket, with a saw12:50
DocScrutinizerno, I dunno such plugs for DIP etc contacts. I'd use copper wire, insert, cut12:51
wpwrakoh, i'll leave holes for the extra contacts. i made a nice 4/6 DIP footprint for that ;-)12:52
DocScrutinizeror simply apply a small drop of 2k-epoxy12:52
wpwrakthat's probably the most professional way :)12:52
wpwrakanyway, if you get it wrong, nothing bad will happen. there are other potential mistakes you could make, such as mis-rotating.12:53
DocScrutinizeryup, sure12:53
wpwrakoh, very good, tyco have not renamed themselves to "TE connectivity". gee. too much brand name recognition ?13:21
wpwraks/not/now/13:22
wpwrakthe future of 3D printing: http://krebsonsecurity.com/2011/09/gang-used-3d-printers-for-atm-skimmers/20:29
larscsomeone recently posted this link: http://www.vimeo.com/29670599 (note lekernel is in the background probably hacking on milkymist)20:33
wpwrakis it a demo to illustrate that streaming video doesn't work ? :)20:36
larscit needs flash i think20:36
wpwrakthat i have. even with firefox. but that doesn't seem to help much.20:37
larschm20:37
larscmaybe it was to offensive ;)20:38
wpwrakah, 33 seconds. then it stopped again.20:38
kristianpaulha, paula i know her :)20:46
kristianpaulwhat small world 20:46
kristianpauli had seems similar histories but with coins, i dint knew it some are made from plastic already20:49
kristianpaulgo a bar, print some before coins, have good beer :)20:49
wpwrakgood idea. making the plastic coin is probably something like 100x as expensive as the real coin ;-)20:52
kristianpaulprintcoin beats bitcoin soon? 20:53
DocScrutinizerisn't bitcoin actually just a very nifty distributed computing project aimed at creating a giant rainbow table? ;-)23:14
kristianpaulkinda yes :)23:15
tsathquestion; is the USB port on the Ben fully functional?23:18
DocScrutinizerhah23:18
Aylawhat does "fully functional" means23:18
tsaththat I could plug in a USB mouse, or other USB devices.23:19
larsctsath: it is not a usb host port23:19
tsathah. ok23:19
larscyou can use your nanonote as a usb mouse though23:19
DocScrutinizerben *is* a "USB mouse"23:19
tsathi see.23:19
larscor keyboard, or soundcard, or pendrive23:19
DocScrutinizermore precisely, ben is a usb peripheral23:20
kristianpauland do not support USB host :)23:20
DocScrutinizersometimes also called gadget iirc23:20
tsathyeath. gadget ethernet is nice.23:21
tsathany plans for Ben 2.0?23:21
Aylawhat about USB host on the MMC slot?23:22
tsathgood question23:23
wpwrakAyla: you mean something like this ? http://lists.en.qi-hardware.com/pipermail/discussion/2011-September/008933.html23:35
Aylayes23:37
Aylasomebody actually started this or is it just a random thought?23:37
wpwrakjust a random thought. so you can still grab it :-)23:38
wpwrakbtw, you may not even need a boost converter for power. i could imagine that quite a lot of USB peripherals also work with VBUS = 3.3 V. but you'd have to give it a try.23:38
AylaI'm a software guy. I'd be lost :)23:38
wpwrakthis would be 99% software :)23:39
AylaYeah. Well, I'd gladly help if somebody takes the project23:39
Aylabut currently I'm working on so many projects at the same time23:39
