rjeffriesis it kristianpaul who is working on gps? anyhow, here is an article04:05
rjeffrieshttp://diydrones.com/profiles/blogs/software-gps-notes04:05
kristianpaulrjeffries: hey04:12
kristianpaulnice article04:12
kristianpaulhmm, fastgps is not that _fast_ actually04:16
kristianpaulwell, thats what book said, also it does serial acquisition not parallel04:21
kristianpaul"Converting the file to 1 bit made no difference.  Here we have altitude from a sample file."04:21
kristianpaulawesome04:21
rjeffriessorta cool, they have limited goal for their drone project04:24
kristianpaulis not clear what are they using for acquisition part, but i guess the "high speed USB microcontroller" is the cypress one all people is using afaik04:26
kristianpaulokg i need some sleep, tomorrow i'll do some comment, also my account is pending aproval..04:27
kristianpaul"MAX2769 front end is just an analog to digital converter" hmm, thats not true at all, at least if you ignore the AGC part..04:30
kristianpaulrjeffries: diydrones have a wiki or source code repo?04:33
qi-bot[commit] Ayla: The FileLister won't list a file if a previous one has the same file name (without path). http://qi-hw.com/p/gmenu2x/6c9713909:32
qi-bot[commit] Ayla: Merge branch 'install_locations' of projects.qi-hardware.com:gmenu2x into install_locations http://qi-hw.com/p/gmenu2x/d0a24ac09:32
qi-bot[commit] Ayla: Fixed the renameSection() and deleteSection() functions to use the new directories. The sections can now be renamed and deleted. http://qi-hw.com/p/gmenu2x/6cb7ce110:13
Aylahi guys11:19
Ayladoes nanonote have /sys/devices/system/cpu/cpu0/cpufreq ?11:19
xiangfuAyla: root@BenNanoNote:/sys/devices/system/cpu/cpu0# ls13:09
xiangfuroot@BenNanoNote:/sys/devices/system/cpu/cpu0#13:09
xiangfuAyla: ^ no. that folder is empty13:09
Aylaah.13:32
Ayla:(13:32
asmanurAyla: hello, i saw you worked on suspend to ram in the nanonote by waking up from time to time, how can it be used ?13:36
AylaI did work on suspend, but not for nanonote13:38
Aylait would be possible to make suspend to RAM work in nanonote using that technic13:38
asmanurbut it involves kernel hacking i guess13:38
Aylano, you could do it in user space13:39
asmanurhow ? there's no wakealarm file on nanonote13:39
Aylayou'd need my RTC patch, I think it has been merged in mainline now13:39
Aylait enables the alarm for jz474013:39
Aylathen the pattern is simple:13:40
Aylaprogram an alarm for in 1 hour, and suspend13:40
asmanurok13:40
Aylawhen resuming, check if the power button (that should be configured as a wake event) is pressed13:40
Aylaif it is not, return to step 1 :)13:41
asmanurbut I have the latest version of openwrt for the nanonote, and there's no such file13:41
Aylayeah, I don't know if they use the 2.6.39 kernel13:42
asmanur2.6.32 here13:42
Aylait's been merged in 2.6.3913:43
asmanurok13:44
asmanuri'll look into it, thaks for your reply :)13:44
Aylahave fun :)13:45
Aylayou could disable the backlight before the first suspend, so that the screen won't flash when the nanonote wakes up for a second13:46
asmanuryeah i do that already13:49
asmanurI remember that under debian it used to work well :/13:50
qi-bot[commit] Ayla: On the skin menu, the ALTLEFT/ALTRIGHT buttons will now respectively decrease/increase the ARGB values by 10. http://qi-hw.com/p/gmenu2x/38a83dd17:41
rjeffrieskristianpaul http://diydrones.com/ does not seem to have a wiki or source repository however they have a forum where you might ask for source. they seem like a friendly and very open group. ding amazing stuff with DIY drones17:52
rohrjeffries in the drone market there is only very little open source18:41
rohmostly there are commercial assholes who havent understood the licenses they sometimes use in wording, but not reality18:41
rjeffriesroh I think that will change. the amateur UAV/drone hardware designs are generally (not always) very open18:42
rohan to be fair.. i havent seen any foss drone do spectacular stuff... mostly they are fully loaded standing in the air18:42
rohrjeffries: nope. the problem is a)money and b) time. these two are usually quite fast filled by commercial interrest as soon as one of the foss guys learns something the rest doesnt know yet.18:43
rohbtw.. drones are one of the most inefficient flight-toys ever. thus it will stay a toy without changing the concept to something like the french paparrazi project (mini glider)18:44
rjeffriesroh you need to get out more. (just kidding) I've watced videos of really excellent drone flights that exhgibit very good autonomous f;ight contro;18:44
rohrjeffries: i was on motodrone event already....18:45
rohrjeffries: i know the technology they use. and i've seen sources. the commercial stuff is useable. the free stuff cannot even properly fill the easy challenges the motodrone people set up as soon as there is a little wind.18:45
rohlast time they changed the challenges to happen inside a huge bunker hall to have less wind, and give some of the drones a chance... not very promising.18:46
rjeffriesroh do you see the challenge as mainly software or also hardware18:46
rohrjeffries: people.18:46
rjeffriesyou must watch different videos than I do, roh <grin>18:47
rohits a question of mindset.18:47
rjeffriesin any case I am not in the DIY drone field I watch from teh sidelines18:47
rjeffriesthe US government is getting rather nervous and may shut it all down18:47
rjeffriesdue to the "T" word and you know what I mean18:48
rjeffriesnew topic18:48
rjeffriesdo you have access to a 3D printer (I thin?)18:48
rjeffriesthink18:49
rohus gov i dont give a shit.18:53
roh;)18:53
rohlegally its not allowed to run a drone without remote and flight on sight.. autnomous isnt a concept which is possible in the legal system afaik18:53
rohthats something the insurance guys need to think about (who is responsible for things a autonomous thing did?)18:54
rohsimilar with responsibility and such for kids ;)18:54
rohwe ha ve a 3d printhead for the mill18:54
rohbut its not 'ready' yet18:54
rohalso we are currently moving the whole lab18:56
rohneed to run now too.. do some measurements18:56
rjeffriesif you are interested in Internet of Things, as I am, this book chapter may be unformative"20:20
rjeffrieshttp://www.linkedin.com/redirect?url=http%3A%2F%2Fwww%2Espringer%2Ecom%2Fcda%2Fcontent%2Fdocument%2Fcda_downloaddocument%2F9783642191565-c1%2Epdf%3FSGWID%3D0-0-45-1112641-p174102062&urlhash=CU95&_t=tracking_anet20:20
wpwrakrjeffries: that EPCglobal sounds scary. UML, XML, ... they should have stopped at "open" ;-)23:25
rjeffriesnot a lot of firms active in fundamental RFID stuff is my reading of this table" http://www.gs1.org/epcglobal/standards/mdid23:36
whitequarkfuck. I won't be able to solder a single CP2102 in my entire life23:50
whitequarkthey all fail. 5 or 6 already23:50
wpwrakwhitequark: how do they fail ? do they just now work or can you detect problems, such as missing contacts or shorts ?23:57
wpwraks/now/not/23:57
whitequarkwpwrak: well, if I use 40/60 soldering paste with RMA, they just do not even try to enumerate (via internal pullup)23:58
whitequarkif I use TT flux-gel (yes, that active one with interesting features), they work... a bit23:58
whitequarkI mean, they sorta work within a temperature interval of around 120-140 deg. C23:59
whitequarkand not outside it.23:59
whitequarkby 'work' I mean that they are enumerated, show in lsusb, I may send some chars etc.23:59
wpwrakrjeffries: the usual suspects when it comes to chip makers, no ?23:59
