2011-10-07 09:27 mmm do you belive this can work with NN , a GSP with 8:10 SPI interface :) http://shop.4dsystems.com.au/modules-on-the-go/292-motg-gps.html 2011-10-07 09:41 i think it should work.. Probably would need to write an SPI driver for it though 2011-10-07 09:48 I have to make a order on this shop for other reasons, I don't have time to hack with it but I can buy a pair it and loan one to any one with knowledge and time to do so 2011-10-07 12:54 Yes it should work, 2011-10-07 12:54 Btw linux dont have already a spi bitbanging  driver ? 2011-10-07 12:55 have a spi ethernet somwhere too 2011-10-07 12:57 ah, no, well, we have werner's spiio :-) 2011-10-07 13:00 oh,  MOTG is how they call to all their 8:10 modules? 2011-10-07 13:00 nice 2011-10-07 13:14 hates blackouts 2011-10-07 13:15 time to import some magic solar panels from china? :) 2011-10-07 13:16 or put some diesel generator on the terrace ... 2011-10-07 13:16 too 2011-10-07 14:00 wpwrak: don't drink so much 2011-10-07 14:02 hehe ;-) not a drop actually. too wet already outside :) 2011-10-07 15:45 The build was successfull, see images here: http://fidelio.qi-hardware.com/~xiangfu/compile-log/openwrt-xburst.full_system-10062011-1136/ 2011-10-07 18:34 is quite happy today 2011-10-07 18:34 http://whitequark.org/blog/2011/10/07/my-first-factory-made-pcbs/ 2011-10-07 18:36 heh, nice :) the "organic" layout would drive me crazy if i had to debug anything, though 2011-10-07 18:36 nice! you didn't make those in Russia, did you? 2011-10-07 18:37 kyak: nope, http://iteadstudio.com has done them. $25, two days in China and two weeks at Russian customs 2011-10-07 18:38 wpwrak: why? this layout reduces the number of vias by factor of 2 or 3. isn't that a simplification? 2011-10-07 18:41 whitequark: really cheap, too :) 2011-10-07 18:42 kyak: that's why. also, while it is not very fast, it is actually faster than to do it in Russia. a friend works for a Zelenograd company which makes sonic fish scanner (or however that is called). they've bought a pcb in Russia, and it'll take ca. 1.5 months to get it 2011-10-07 18:42 and of course it is more expensive. 2011-10-07 18:44 whitequark: (layout) naw, i just mean the same topology but with straight lines. makes it easier to spot anomalies and to follow traces 2011-10-07 18:54 wpwrak: ah. maybe. I'm not very experienced in that, as you may guess :D 2011-10-07 18:54 there is even a stupid error: no thermals 2011-10-07 18:54 that'll be a pain 2011-10-07 18:55 you mean thermal relief ? yeah. you'll suffer for that ;-) 2011-10-07 18:56 luckily, there are not so many pads/pins with this issue 2011-10-07 18:57 they are called `thermals' in Eagle, and I didn't seen any references in other places. Thanks, now I know how that's called 2011-10-07 18:57 i think the openmoko debug board (v2) had the same flaw. of course, you don't notice during industrial SMT because the reflow oven heats the whole board. but soldering those optional connector was ... surprisingly difficult 2011-10-07 18:57 I've seen something like that in a router 2011-10-07 18:58 there was a debug port, but without thermal reliefs. 2011-10-07 18:58 even worse, the holes were filled with SnAuCu solder 2011-10-07 18:59 ... that was the moment I realized that a RoES directive should be written. you know, Restriction of Engineer's Sufferings 2011-10-07 18:59 and when soldering you look at your soldering station and think "moar power igor!!" ;) 2011-10-07 18:59 I think I've spent a whole hour soldering three freaking holes. 2011-10-07 18:59 sounds like "snafu" ;-) 2011-10-07 19:00 wpwrak: that's what I read at first as well :) 2011-10-07 19:00 indeed. 2011-10-07 19:00 (thermal relief) just checked it ... and i got it right :) https://en.wikipedia.org/wiki/Thermal_relief_pad 2011-10-07 19:01 ah, SnAuCu is ROHS solder.. then snafu makes sense 2011-10-07 19:02 whitequark: you could have used a drill to empty the hole ;-)) 2011-10-07 19:03 that metals really should go where they belong. gold to plating and intra-IC connections. silver to rings, necklaces and relay contacts, as all of them look nicer with it 2011-10-07 19:04 wpwrak: ah. a drill. I even had one. thanks, I'll remember that 2011-10-07 21:18 wpwrak: have you seen this?  http://shop.4dsystems.com.au/modules-on-the-go/292-motg-gps.html 2011-10-07 21:20 tuxbrain_HxxHhzo: cute ! :) but i'm still waiting for someone to show off one of these: http://shop.4dsystems.com.au/modules-on-the-go/291-motg-96.html 2011-10-07 21:22 show off? sorry what than means? 2011-10-07 21:22 whitequark: btw, here's a more detailed discussion of thermal relief: http://www.edaboard.com/thread38506.html 2011-10-07 21:22 tuxbrain_HxxHhzo: get one, make it work, post pictures :) 2011-10-07 21:24 I can see the utility of the gps , apart of the cool factor, what is the utiliti to add such second screen to NN? (I can buy one of those and if you help me with the app I can also make the photos) 2011-10-07 21:25 isn't the coolness factor enough reason ? ;-) 2011-10-07 21:33 http://www.4dsystems.com.au/downloads/MOTG/MOTG-96/Docs/MOTG_Displays_C_Lib.c , do you think can implement spi_* fuctions they call in in his library? 2011-10-07 21:36 probably. are there schematics of the way they use uSD ? 2011-10-07 21:41 they have full Datasheet here, http://www.4dsystems.com.au/downloads/MOTG/MOTG-96/Docs/MOTG-96-DS-rev1.pdf 2011-10-07 21:54 heh, the purest SPI. sure. it's exactly like the SPI you've already used with the arduino. 2011-10-07 22:02 Looks promising :) , Is the Nanomap developer already here? I think we can bost this app connecting a real GPS to NN :), also NN can become a real GPS cool gadget for OpenStreet mappers creating some app to edit streets names or so... 2011-10-07 22:03 They also mention a WiFI MOTG device but I can't see any info about it... I will ask 2011-10-07 22:09 they seem to be a good place for uSD gadgets :) 2011-10-07 22:09 well, faux-uSD ;-) 2011-10-07 22:09 faux-uSD? 2011-10-07 22:10 if looks like uSD but doesn't speak uSD 2011-10-07 22:11 placing order for the gps and the oled ,do you think the program MOTG will also be needed? http://shop.4dsystems.com.au/modules-on-the-go/294-motg-programmer.html 2011-10-07 22:14 naw, that's just some -to-faux-uSD converter. we don't need that. we have the ben ;-) 2011-10-07 22:14 ok :) 2011-10-07 22:16 done 2011-10-07 22:18 Also asked the reseller conditions, lets see, maybe we can increase the NN accesories in Tuxbrain 2011-10-07 22:22 btw, any changes in ben sales recently ? 2011-10-07 22:23 or just constantly low ? 2011-10-07 22:26 [commit] Werner Almesberger: m1rc3/norruption/: infrastructure and test script for temperature measurements (master) http://qi-hw.com/p/wernermisc/8741616 2011-10-07 22:28 low, but I think I have slightly more sales than wolfgang, I have sell two this week :P 2011-10-07 22:30 whee ! :) and how are atben/atusb doing ? 2011-10-07 22:33 freeze,  I hope blogic  project can re-activate the thing 2011-10-07 22:33 i remenber nanomap had support for gpsd, but it never worked for me.. 2011-10-07 22:34 is built-in the atena for this gps receiver? 2011-10-07 22:34 (freeze) :-( 2011-10-07 22:34 and ubb ? 2011-10-07 22:35 s/atena/antena 2011-10-07 22:35 If not was for Arduino and Efika and seem than the rugged PDA  also start to catch some interest Tuxbrain has closed some months ago... 2011-10-07 22:36 kristianpaul: yes is buit in 2011-10-07 22:36 ubb as freeze as atben 2011-10-07 22:36 wow there is even a RF24G. wonder more specs about that 2011-10-07 22:36 tuxbrain: you mean atusb rules sales? 2011-10-07 22:37 gnats--;  /* first one this spring */ 2011-10-07 22:37 all Qi related products are a very low (or totally frozen ) on sales at least in tuxbrain 2011-10-07 22:38 hmm. bad :-( 2011-10-07 22:38 :-/ 2011-10-07 22:39 ha practicaly you can skip NEMA, seems that module provides latitude and longitude with some reads 2011-10-07 22:39 that is good or bad? :P 2011-10-07 22:40 good :) 2011-10-07 22:40 wpwrak: is that spiio what you meantioned tuxbrain already tested with an arduino? 2011-10-07 22:40 ah nv, NEMA actually does that ;-) 2011-10-07 22:40 it's this piece of high-tech: http://projects.qi-hardware.com/index.php/p/wernermisc/source/tree/master/spiio/ 2011-10-07 22:41 yes reading it now looks quite simple !! 2011-10-07 22:41 amazing 2011-10-07 22:41 kristianpaul: yes it works, but I screewed some timer in the arduino part that doesn't let me use the delay function after SPI communication, but a part than that it works like a charm 2011-10-07 22:41 good to know 2011-10-07 22:43 I think is the Lib I use to make arduino spi slave, is not the official due the official one is only master, I had no time/knowledge to review what has messed with timer in charge of delay function 2011-10-07 22:43 [commit] Werner Almesberger: m1rc3/norruption/mtemp: so Ubuntu now has a usbtmc module that gets in the way. rmmod :) (master) http://qi-hw.com/p/wernermisc/84b2d41 2011-10-07 22:45 wpwrak: a rmmod inside a loop, is that dangerous it came back again? :) 2011-10-07 22:48 mmm 4DG aslo has some interesting TTL cameras :P just for still pictures but interesting http://shop.4dsystems.com.au/camera-and-imaging-modules/256-9200.html 2011-10-07 22:51 that ttl is 3v3 lets see 2011-10-07 22:51 kristianpaul: seems that the device disconnects and re-enumerates occasionally. and then the module comes back. i should look into a proper way to disable it. or use the usbtmc module instead of my own driver. 2011-10-07 22:51 yes :) 2011-10-07 22:52 wpwrak: may be because the 30m? :) 2011-10-07 22:52 tuxbrain: very coold stuff on that shop, nice finding ! 2011-10-07 22:52 (30m) maybe. will be fun if it's really highly unreliable. 2011-10-07 22:55 .. because i'll also have m1-jtag and labsw on that hub 2011-10-07 23:10 wpwrak: you for sure can answer this and scratch my itch: is scheduler plugged hard into kernel, or can it get swapped, at least at boot-time? 2011-10-07 23:12 hmm, good question. you mean the CPU scheduler, i assume. (there are other schedulers, for disk, network, etc. these are all modular) 2011-10-07 23:12 yup, cpu, as in bfs/cfs 2011-10-07 23:12 the cpu scheduler used to be fixed. but that may have changed. 2011-10-07 23:13 I guess it hasn't then... 2011-10-07 23:14 yeah, it's modular no 2011-10-07 23:14 w 2011-10-07 23:14 indeed? 2011-10-07 23:14 wow, since when? (kernel version) 2011-10-07 23:15 but now 100% modular. there's some hard-coded knowledge about the schedulers 2011-10-07 23:16 there are four schedulers: stoptask, rt, fair, and idletask 2011-10-07 23:17 (tires to kill a kernel fork done for bfs for the giggles, err "because it's allegedly way faster" without any decent comarative statistics on the target platform) 2011-10-07 23:17 ;-) 2011-10-07 23:19 that is, that's the status of "Flesh-Eating Bats with Fangs" aka 2.6.38 2011-10-07 23:19 https://lbtwiki.cern.ch/bin/view/Online/WebHome sysdmin wiki cern? 2011-10-07 23:22 wpwrak: pointer to that bfs-fork: http://talk.maemo.org/showthread.php?t=78110&page=4 2011-10-07 23:49 actually post#27,30 are funny.
