Hurrian | LjL-Alps: a SDR on the Neo900 would be tons of fun. | 02:48 |
LjL-Alps | Hurrian: i think DocScrutinizer05 already has that covered | 02:49 |
LjL-Alps | but yes it would | 02:49 |
LjL-Alps | to be honest i'd be content with RTLSDR support on the original N900 :P | 02:49 |
DocScrutinizer05 | I elaborated on this and suggested a direct link from baseband to shared RAM to feed the signal to DSP. But this will be an unbearable power hog | 02:50 |
Hurrian | …but I think the FCC would hang us should we advertise a high-gain SDR on the Neo900 :P | 02:50 |
DocScrutinizer05 | LjL-Alps: I discussed RTLSDR support on N900 with a few guys, and it might be feasible | 02:51 |

DocScrutinizer05 | gnuradio???? are you mad? or simply the weirdes hacker I ever heard of | 02:53 |

LjL-Alps | i guess so | 02:57 |
DocScrutinizer05 | thanks, I already had a hurting back | 02:57 |
LjL-Alps | but it doesn't matter, i'm clueless and never managed to receive anything with my RTLSDR! | 02:57 |
LjL-Alps | except for bus drivers talking on the phone | 02:57 |

DocScrutinizer05 | stereo *pilot* is at 16kHz iirc! | 03:45 |
LjL-Alps | well it only works if i keep the two thingies at like 10cm distance | 03:45 |
RiD | LjL you could market that as "nfc music streaming" | 03:46 |
DocScrutinizer05 | and stereo separation is basically nonexistent | 03:46 |
LjL-Alps | DocScrutinizer05, i think you're no teenager, don't fool us into thinking you can hear that | 03:46 |

DocScrutinizer05 | MEH! | 03:46 |
RiD | na, DocScrutinizer05 has a good point | 03:46 |
LjL-Alps | RiD: yes, but i'll leave the expansion of "NFC" undefined | 03:47 |
RiD | if it's anything like a 44100 vs 16khz wav, the difference is enormous | 03:47 |
DocScrutinizer05 | http://www.youtube.com/watch?v=FEMu5XY31DY | 03:47 |
LjL-Alps | RiD: uhm that's different though, a 16khz wav means you only get frequencies up to 8khz | 03:48 |
LjL-Alps | which is a fair bit lowre | 03:48 |

LjL-Alps | the thing is, i'm pretty sure with the N900's extremely powerful transmitter, you never really reach the point where you have to worry about theoretical FM radio quality constraints ;( | 03:50 |
*** bef0rd has joined #maemo | 03:50 | |
LjL-Alps | DocScrutinizer05, if you folks actually managed to put an RTLSDR-like SDR inside the N900, that would give you worldwide broadcast radio coverage as a bonus - as today, various countries use DAB or DMB-T or 1seg or whatever as FM radio alternatives/replacements | 03:52 |
*** bef0rd has quit IRC | 03:52 | |
LjL-Alps | at least if the processor were fast enough to decode any of that | 03:52 |
*** bef0rd has joined #maemo | 03:52 | |
DocScrutinizer05 | well, a 1GHz omap3630 with DSP should lift that | 03:52 |
DocScrutinizer05 | the problem is it keeps CPU busy, though maybe not much more than mp3-playback | 03:53 |
LjL-Alps | yeah it's not going to be battery efficient for sure | 03:54 |
DocScrutinizer05 | tbh with our weird PA based AP centric audio concept, nothing audio is exactly a battery smiler | 03:54 |
*** Sysaxed has quit IRC | 03:55 | |
RiD | well, 24hours of music is not bad is it? | 03:55 |
DocScrutinizer05 | it's so weeeeeeird, exactly what you never ever musr do when designing sw architecture for embedded | 03:55 |
LjL-Alps | why stop at audio, DocScrutinizer05? these SDR thingies *were* originally meant as TV decoders, after all! | 03:55 |
*** bef0rd has quit IRC | 03:55 | |
LjL-Alps | 1 frame per minute tv would be nice | 03:56 |
RiD | voiced slideshow | 03:56 |
DocScrutinizer05 | sure, I never said "stop at audio". Actually for audio any cheesy USB or other attaching method would suffice. I suggested shared RAM and DSP for DVB | 03:56 |
LjL-Alps | oh you really want to do DVB | 03:57 |
DocScrutinizer05 | sure, when i already got a SDR hooked up to my OMAP3, why not? | 03:57 |
LjL-Alps | i guess! | 03:58 |
LjL-Alps | why not do GSM as well, and ditch the modem :P | 03:58 |
DocScrutinizer05 | when it can playback flash and mpeg2 and mpeg4 and whatnot, why not dvb? | 03:58 |
DocScrutinizer05 | actually with a rtl2823 dvb is probably easier to cpu than FM | 03:59 |
*** bef0rd has joined #maemo | 03:59 | |
LjL-Alps | DocScrutinizer05, well i dunno, but the RTLSDR's bandwidth isn't even enough to send in the raw i/q for DVB (which is 6Mhz iirc) | 04:00 |
LjL-Alps | i realize we're not talking about the actual RTLSDR here | 04:00 |
LjL-Alps | but still, that seems like a lot of data to handle | 04:00 |
DocScrutinizer05 | you're aware that rtl2832 allegedly does DVB decoding on chip, and sends a mpeg or whatever stream? | 04:01 |
LjL-Alps | yes | 04:02 |
LjL-Alps | that's why i said the bandwidth isn't enough to send the raw data :P | 04:02 |
LjL-Alps | i don't know anyway. it just seemed like a lot to handle, intuitively, but i'm not going to defend that position | 04:02 |
DocScrutinizer05 | ~800*480*25*3 | 04:03 |
infobot | 28800000 | 04:03 |
DocScrutinizer05 | 28MB/s video bandwidth? | 04:04 |
DocScrutinizer05 | DSP handling that | 04:04 |
LjL-Alps | right but the actual bandwidth needed to get the radio signal in is going to be a lot more | 04:04 |
LjL-Alps | ATSC is even worse, 8Mhz | 04:05 |
LjL-Alps | well maybe not really a lot more, since i'm talking compressed video on a radio i/q stream, and you're talking uncompressed bitmaps | 04:06 |
DocScrutinizer05 | aiui the IQ scheme is meant to run at nyquist and still get a meaningful data stream that even holds info about phase | 04:06 |
DocScrutinizer05 | so for 8MHz you need 32MB/s with 8bit resolution | 04:07 |
DocScrutinizer05 | 8Mhz -> 16Ms/s with 8bit I and 8bit Q | 04:08 |
DocScrutinizer05 | but I#m no expert in that digital signal processing stuff | 04:09 |
LjL-Alps | me neither. i just know that SDRs are expensive, and the RTLSDR seemed like a miracle already with its "really wide" 3Msps... but, economies of scale i guess | 04:10 |
DocScrutinizer05 | I just know the purpose of DVB is to reduce needed bandwidth, not to increase it | 04:10 |
LjL-Alps | DocScrutinizer05: well yeah thanks to MPEG | 04:10 |
LjL-Alps | but a few channels are crammed into one stream so you still need to read in a lot of stuff, and then ditch some | 04:11 |
LjL-Alps | TV channels i mean | 04:11 |
DocScrutinizer05 | sure | 04:12 |
DocScrutinizer05 | USB highspeed is 480Mbps | 04:12 |
DocScrutinizer05 | and CPU handles that easily | 04:12 |
DocScrutinizer05 | *usually* ;-P | 04:12 |
LjL-Alps | the HackRF thing apparently can go down to 10MHz according to "leaked info", says wikipedia or some other wiki i was reading a moment ago | 04:12 |
LjL-Alps | 10MHz to 6GHz, now, that's... something | 04:13 |

robbiethe1st | I'm guessing that if my computer was compromised, this connection to IRC would be from a RAT, and he was attempting to establish communication, load up some new piece of malware | 04:21 |

Tekk_ | hmm | 04:55 |
Tekk_ | it seems that app manager has decided that I have no catalogs and I have no apps installed | 04:57 |
mashina | it doew that | 04:57 |
mashina | just restart app cat | 04:57 |
mashina | or use apt | 04:57 |
Tekk_ | app cat? | 04:58 |
DocScrutinizer05 | nonsense | 04:58 |
DocScrutinizer05 | just wait! | 04:58 |
mashina | app cataloguw | 04:58 |
mashina | silly keyboard | 04:58 |
DocScrutinizer05 | app manager needs up to 15 minutes to display any list of apps, when you enabled a lot of crammed catalogs | 04:59 |
Tekk_ | DocScrutinizer05: no, not now showing anything | 04:59 |
Tekk_ | but "you have no app catalogs enabled" | 04:59 |
Tekk_ | and when you go into app catalogs, it doesn't see any | 04:59 |
Tekk_ | not not showing* | 04:59 |
DocScrutinizer05 | then you messed up the catalogs file. That's a result of trying to avouid HAM and configuring catalogs in packages.list or whatever the names of thpose files | 05:00 |
DocScrutinizer05 | http://maemo.cloud-7.de/maemo5/etc/apt/ http://maemo.cloud-7.de/maemo5/etc/hildon-application-manager/ | 05:02 |
Tekk_ | yeah, it actually seems like a force close on HAM fixed it | 05:02 |
DocScrutinizer05 | don't think you can edit those files any way you like, it is prone to mess up stuff. | 05:03 |
robbiethe1st | Why not just use apt? | 05:03 |
Tekk_ | DocScrutinizer05: I hadn't edited it | 05:03 |
DocScrutinizer05 | because for apt you need to know what you're doing, and what maemo does. maemo is NOT debian | 05:03 |
Tekk_ | but I did use apt a bit | 05:03 |
Tekk_ | but it seems that I've reverted the damage | 05:03 |
DocScrutinizer05 | apt is fine for a lot of standard stuff, especially command line tools | 05:05 |
*** bef0rd has quit IRC | 05:05 | |
*** bef0rd has joined #maemo | 05:05 | |
DocScrutinizer05 | for installing typical maemo specific packages or system stuff, you should resort to HAM | 05:05 |
robbiethe1st | ...I don't think I've started HAM in like two, three years | 05:06 |
DocScrutinizer05 | *shrug* | 05:06 |
DocScrutinizer05 | may I ask how you do upgrades then? | 05:06 |
Tekk_ | upgrade, presumbly? | 05:07 |
robbiethe1st | ^^ | 05:07 |
robbiethe1st | apt-get update && apt-get upgrade | 05:07 |
DocScrutinizer05 | good luck | 05:07 |
robbiethe1st | It seems to work | 05:07 |
DocScrutinizer05 | kills system | 05:07 |
DocScrutinizer05 | emphasis on 2seems" | 05:07 |
DocScrutinizer05 | you'll notice the broken or conflicting or autoremoved or uninstalled packages 8 weeks later | 05:08 |
robbiethe1st | I've killed the system a few times -- always due to friging optfs getting corrupted after a while; I've actually been able to recover from a pretty badly mangled system(i.e. optfs backup being from a year older than my rootfs) | 05:08 |
robbiethe1st | it took apt-get install --reinstalling a bunch of optified stuff, but after doing that, it works | 05:09 |
DocScrutinizer05 | or never, while al the time you wonder why XY segfaults or acts weird | 05:09 |
robbiethe1st | You mean, aside from OCing? | 05:09 |
robbiethe1st | I'm running 950mhz, at probably 99.9% stability, but I've had crashes oh, every month or two. But then again, I also almost never preemptively reboot it | 05:10 |
robbiethe1st | unlike some | 05:10 |
DocScrutinizer05 | I basically never reboot N900, and I had no crash since err 3 years | 05:10 |
robbiethe1st | I suppose that I don't have apt problems because I know enough not to press Y when it asks to remove dozens of things | 05:10 |
robbiethe1st | You also aren't OCing, are you? | 05:11 |
robbiethe1st | for me, a crash every couple of months and a rebuild every year is worth the extra 50% speed. | 05:11 |
Tekk_ | I temporarily bumped up to 900 | 05:11 |
Tekk_ | to see if pcsx would run decently, it didn't | 05:11 |
Tekk_ | so I brought it back down | 05:11 |
DocScrutinizer05 | 50% speed? maybe in clock divider | 05:11 |
robbiethe1st | CPU wise, 950mhz is slightly over 50% faster than 600mhz. | 05:12 |
DocScrutinizer05 | ALU wise | 05:12 |
Tekk_ | robbiethe1st: why do you bother with overclock? | 05:12 |
robbiethe1st | Because it /seriously/ helps | 05:12 |
DocScrutinizer05 | CPU is more than ALU and PC | 05:12 |
robbiethe1st | It really helps with browser speed, which is what I do most of the time | 05:13 |
Tekk_ | with what though? granted, I've only been fiddling for a day or so, but I haven't yet really been hurting for cpu power | 05:13 |
DocScrutinizer05 | I wouldn't even know why I'd need any such help | 05:13 |
robbiethe1st | JS heavy pages, like Slashdot... | 05:13 |
Tekk_ | /. works fine with noscript, as long as you don't want comments | 05:13 |
Tekk_ | is there a noscript for fennec? | 05:13 |
robbiethe1st | ...And that's the whole point of slashdot | 05:13 |
robbiethe1st | the comments are the important point. With stock MicroB, I can browse slashdot's desktop site just like I would otherwise, if a bit slower | 05:14 |
robbiethe1st | MicroB, I might add, is the only browser I know of with a good implementation of mouse-cursor mode | 05:14 |
DocScrutinizer05 | the bottleneck with browsing is the RAM, and swap. You can't speed up swap by OC | 05:15 |
robbiethe1st | Depends on the pages. | 05:15 |
Tekk_ | maybe he's really tweaked swappolube to the point where cpu is, I guess | 05:15 |
robbiethe1st | I did that a while back; it's definitely faster than it was stock. | 05:15 |
DocScrutinizer05 | and the most popular mistake in microb that brings it to a grinding halt is adblock | 05:15 |
Tekk_ | really? | 05:16 |
robbiethe1st | Plus, sure, on lightweight webpages, swap is probably the limiting factor. Slashdot is where it | 05:16 |
*** triggerhappy has quit IRC | 05:16 | |
robbiethe1st | It's most noticable, and that's horribly JS heavy | 05:16 |
robbiethe1st | Plus, I usually open up several tabs/windows at once, have them load in the background, Between stock 600mhz and 950mhz(changing only the governor), it's noticable | 05:17 |
robbiethe1st | (In the past, I occasionally had a crash and PK wouldn't load my preset as default. I'm sitting there wondering "why is it so slow" "Oh..." | 05:17 |
robbiethe1st | Also(in the past), games. 950mhz vs 600mhz really helps with something like Runescape(which I was able to get to run, at like 1fps). 1ghz and above work fine for me(I can get to 1.15ghz), but create too much heat when running flat out | 05:19 |
robbiethe1st | at 950mhz, it doesn't seem to get nearly as hot(though I haven't stressed it like this in quite a while) | 05:19 |
Tekk_ | robbiethe1st: you should try runescape 3 :D | 05:20 |
Tekk_ | I was getting like 3 fps on a dual core at 3.0 ghz with 4 gb of ram | 05:21 |
robbiethe1st | Yeah...No. | 05:21 |
robbiethe1st | OSRS is where it's at | 05:21 |
robbiethe1st | Though I don't even play that much anymore | 05:21 |
Tekk_ | I used to play on rscangel | 05:22 |
robbiethe1st | << (and, on rs3/rs2 robbiethe2nd) | 05:22 |
robbiethe1st | Speaking of which, time to see if I can get OSRS working on my N900 again | 05:24 |

LjL-Alps | hey, i wonder if this double-USB-charger i have can be used to connect two data cables together so i end up with the correct configuration ;( | 17:08 |
LjL-Alps | trying | 17:08 |
LjL-Alps | ah i can't, i need an extension cord that i lack due to space issues | 17:09 |
DocScrutinizer05 | LjL-Alps: actually you probably can rework that charger to make an awesome OTG adapter | 17:09 |
DocScrutinizer05 | caveat: | 17:09 |

infobot | hmm... hostmode-powered is http://talk.maemo.org/showthread.php?p=921203#post921203 | 17:10 |
DocScrutinizer05 | xes: (already mirrored) yeah, xesget works fine, just datarate was like 22kB/s for the gnuradio 8MB blob | 17:11 |
xes | DocScrutinizer05: i know it was you!! :-) i was re-upping that tar with a fixed file :-) | 17:11 |
xes | DocScrutinizer05: that script takes care only of vboost? Right? ..not high/full hostmode | 17:12 |
DocScrutinizer05 | right | 17:12 |
xes | no way to switch all things in the right way from shell before start with rtl-sdr tools? | 17:13 |
DocScrutinizer05 | there are 2 commented lines that allude to actually enabling hostmode | 17:13 |
DocScrutinizer05 | #sleep 1 | 17:14 |
DocScrutinizer05 | #echo F >/proc/driver/musb-hdrc | 17:14 |
LjL-Alps | DocScrutinizer05: err, looks like greek to me right now (actually no, i can read some greek), i will read the whole thread carefully later, but long story short, am i likely to fry something if i just try connecting the N900 to (say) an MP3 player via this charger, while it's (not) plugged into the wall? | 17:14 |
DocScrutinizer05 | add another few and you should be mostly fine | 17:14 |
DocScrutinizer05 | LjL-Alps: the problem might be huge buffer capacitor in charger's VBUS output, which could cause inrush spike on N900 enabling VBUS and thus the bq25150 *might* decide to shut down. You'll notice this with my improved booston script, it rises a notifier. No particular risk to damage anything | 17:17 |

DocScrutinizer05 | xes: how bad is usb hostmode bandwith bottleneck? | 17:29 |
DocScrutinizer05 | xes: do you see lots of underruns? | 17:29 |
DocScrutinizer05 | or lots of dropped samples or whatever rtl_fm might complain about? | 17:30 |
DocScrutinizer05 | I asked keenerd about reducing samplerathe, he said in theory there's a 250k sample mode but that sucks since you can't get any clean multiple of your rx frequency | 17:31 |
DocScrutinizer05 | or sth like that, so you'd need resampling | 17:31 |
DocScrutinizer05 | so far rtl_fm doesn't support it due to that | 17:32 |
DocScrutinizer05 | he *might* implement it eventually, but that increases cpu load then, due to resampling | 17:33 |
DocScrutinizer05 | [2013-08-30 16:06:21] <keenerd> Hrm, using 250k is not going to be easy. To make the math as fast and friendly as possible, the sample rate is choosen such that you don't need to do any fractional resampling. Fixed sample rates kind of kill that. | 17:34 |

DocScrutinizer05 | pukeaudio sucks donkey balls | 17:51 |
DocScrutinizer05 | maybe worth stoppiing it all together before starting aplay | 17:52 |
DocScrutinizer05 | it's >>aplay -> alsa -> soundcard[[ then, rather than >>aplay -> PA-ALSA-compatlayer -> PA -> alsa -> soundcard[[ | 17:53 |
DocScrutinizer05 | where "PA" in fact is some terrible stuff including XPROT and a lot of resmapling and mixing and equalizing and whatnot | 17:54 |
DocScrutinizer05 | you'll need to use alsamixer -c0 then, to adjust volume etc | 17:55 |
xes | the better thing would be to have an initialization script that prepares all the things before run anything concernin rtl-sdr | 17:56 |
korhojoa | ~hostmode-powered | 17:56 |
infobot | hostmode-powered is probably http://talk.maemo.org/showthread.php?p=921203#post921203 | 17:56 |
DocScrutinizer05 | xes: sure :-) | 17:56 |
DocScrutinizer05 | xes: definitely this isn't rev1.0 yet | 17:56 |
DocScrutinizer05 | ;-) | 17:57 |
xes | so, enable hostmode, vboost (disable/enable/../) until lsusb can see the device, stop everything that could interfere with sdr. Then "ready to go" | 18:00 |
DocScrutinizer05 | xes: I even might consider writing a nice script that takes care about PA, about hostmode, even hostmode-powered, and all that, and finally starts rtl_fm (in a loop, till aborted?). Just I CBA to mess with messybox scripting | 18:01 |
DocScrutinizer05 | err, yes | 18:01 |

korhojoa | mail one to me. | 18:04 |
korhojoa | where did you buy yours? | 18:04 |
DocScrutinizer05 | one is a cheesy but easily available and tiny logilink "va0002" that I bought ages ago, the other two are terratec based on E4000 tuner which I ordered a 2 weeks ago at fleabay | 18:05 |
DocScrutinizer05 | http://www.amazon.de/gp/offer-listing/B007EB995U/ | 18:06 |
DocScrutinizer05 | those are huge monsters | 18:06 |
DocScrutinizer05 | about 5 times the size (and 20 times the volume) of the logilink | 18:07 |
DocScrutinizer05 | well, twice+ the length, and 5 times the volume ;-) | 18:07 |
xes | this could be an option: http://www.ebay.it/itm/New-USB-2-0-DVB-T-STICK-RTL2832U-R820T-TV-DVD-MPEG-2-FM-radio-DAB-radio-WMA-/171108255911?pt=US_Video_Capture_TV_Tuner_Cards&hash=item27d6d8c8a7 | 18:07 |

*** arcean has joined #maemo | 18:09 | |
DocScrutinizer05 | actually that's exactly the offer I buy | 18:09 |
DocScrutinizer05 | for the va0002 you *need* parameter -g40 in rtl_fm, for terratec this very option is detrimental | 18:10 |

*** dhbiker has quit IRC | 18:14 | |
DocScrutinizer05 | tbh the terratec is a scam, it doesn't even have the IR RX mounted, and consequently comes without any IR-remote | 18:14 |
DocScrutinizer05 | not that you could actually use that remote control under linux anyway | 18:14 |
DocScrutinizer05 | but the logilink been cheaper and came with a remote control | 18:15 |
xes | so, DocScrutinizer05 have you choosed the key to try? Does it works? | 18:15 |

DocScrutinizer05 | it's a shame how every single model of those rtl2832 keys is crippled from what it could be to something that's barely enough to do what it must do, for sole purpose of saving a 50ct on BOM | 19:00 |
DocScrutinizer05 | better crystal, some pads to solder on RF-feed-thru and to daisychain clock, and particularly a LNA in RF-in, and that thing could rock | 19:03 |
DocScrutinizer05 | actually a phantom-feed for LNA in antenna would already help a lot | 19:04 |
