#qi-hardware IRC log for Wednesday, 2013-07-24

kristianpaulhmm mp4 dont bet00:36
kristianpaulogv was improved by david k i remenber00:36
qi-bot[commit] Werner Almesberger: atusb/fw/mac.c: add section titles (master) http://qi-hw.com/p/ben-wpan/6416fa811:04
viricin linux, AP, is it possible to do some kind of filtering, like "clients connected with SNR < 70dB, don't connect"?14:05
whitequarkI don't think that there is a builtin feature for that14:14
whitequarkit should be reasonably trivial to add though14:14
whitequarkalso, 70 dB SNR is... a lot :D14:14
viricI meant -70dB :)14:37
viricand I thought I was asking at #openwrt ;)14:37
larscthat's not so much14:46
virickristianpaul: I read about GPS:15:24
viric"GPS signals receivers - as could be used in mobile phones - are required                          15:24
viricto shut-down when the device realizes itself to be moving faster than 1,200                        15:24
viricmph and is at an altitude higher than 60,000 feet."                                                15:24
viric(to avoid they being used in intercontinental missiles)15:25
whitequarksparkfun sells gps modules without altitude lock, though I believe they still have speed lock15:27
viricwasn't kristianpaul making a gps for intercontinental missiles?15:27
larscthe only thing missing are the IVMs ;)15:44
wpwrakviric: so, Dr. Strangelove Jr., how is your project today ? ;-)16:09
kristianpaulviric: misil? no18:09
kristianpaulbut yes thats posible18:10
kristianpaulah wait18:10
Action: kristianpaul finishing reading backlog18:10
larscdo you need to compensate for velocity when receiving a gps signal?18:11
kristianpaulwell you always neeed to compensate dopplet and others variables18:11
kristianpaulso i think yo do18:12
kristianpaulbut satellites moves faster than your actully could?..18:15
larscyea, i was wondering if you local velocity matters at some point18:15
kristianpaulfor rtk aplications it matters for sure, but then we have alternative navigation18:19
kristianpauli dont think you can let just gps or glonass do the fix, for that accuracy in real time18:19
kristianpaulat least you are just mapping and can afford post-processing18:20
kristianpaulviric: second, looking wikipedia article about the subject18:20
kristianpaulviric: yes all becuse then http://en.wikipedia.org/wiki/CoCom18:29
kristianpaulyes i was (hold) working on an embedded gps receiver inside a fpga (m1)18:31
wpwrakstep 1: design GPS system without speed and altitude restrictions. step 2: sell it to north korea. a major difficulty may be to find something north korea could give you in return, though.18:31
viricI also had in mind north corea18:32
kristianpaulalso i think Artyom  (from gnss-sdr.ru )get something to work but had troubles with locking 18:32
kristianpaulwpwrak: no need http://www.gnss-sdr.org/18:32
kristianpaulbut of course sdr driven by python seems not that efficient..18:33
kristianpaulportable and etc :)18:33
larsca rocket has enough energy18:34
kristianpauland the key is the correlator, piski guys did what seems a great job releasing and what seems to a fresh libraries (in c) for some glue gnss-gps processing18:35
wpwrakwow. catalunya has the tld .cat ? didn't know that. and of course, someone snatched lol.cat :-(18:35
kristianpaulbut the fpga model is not in their plans las time i asked18:35
kristianpaul:-( <- :-(18:35
qi-bot[commit] Werner Almesberger: atusb/fw/mac.c (next_buf): dedicated function for incrementing buffer indices (buffer-frames) http://qi-hw.com/p/ben-wpan/998ac7e20:21
qi-bot[commit] Werner Almesberger: atusb/fw/Makefile: improve size reporting (show segment sizes) (buffer-frames) http://qi-hw.com/p/ben-wpan/070677320:21

lkcl_hi folks looking to get the kicad source for the nanonote,22:30
lkcl_isn't working22:31
lkcl_although.... i thiiiink.... that name gave me a lead22:31
lkcl_and i've already got it :)22:31
wpwrakavt2 is not quite the ben. it's basically an improved ben design. has usb and i think twice the RAM.22:33
wpwrakusb host i mena22:33
pcercueitwice the RAM?22:33
pcercuei64MB? :p22:33
lkcl_ooo 64mb woow22:34
lkcl_i'm looking for a DDR1 or SDRAM part22:34
lkcl_it's for a GPL EOMA68 project, a router/NAS using the RTL818922:34
lkcl_that P3V56S.... that's what i need, right?22:35
lkcl_awesome... memory... but no processor :)22:39
Action: lkcl_ happy22:41
