<DocScrutinizer05> also I didn't plan to check all possible numbers from 000 to 999. I only planned to check a few 114 etc numbers
<DocScrutinizer05> I _know_ 112 and 110 works
<DocScrutinizer05> I'm pretty sure not much else will, though
<DocScrutinizer05> 0800 should work
<DocScrutinizer05> the funny detail that's caused by historical reasons is: there's no end-of-number marker of any kind in POTS. Not even in ISDN. The network needs to check for a valid number after each single digit you entered
<DocScrutinizer05> there's a certain short delay before such check happens (to reduce workload on the network infra), so for a valid number 123 you actually _can_ get a "invalid number" signal when you enter 1234 fast enough
<DocScrutinizer05> on some exchange infra. Not on other type of infra

<edwin1> how is battery life going to be for Neo900? I see 1320mAh in the feasibility study but not on the specs page, but of course what I'm really interested in is standby time on 2G/3G. Is it possible to estimate that based on the modem or is it highly dependent on the network operator/signal strenght etc.?
<DocScrutinizer05> both
<DocScrutinizer05> :-)
<DocScrutinizer05> standby time should be around same as fro N900
jwhitmore has joined #neo900
<edwin1> is it possible to fit a different/larger battery or given the space constraints thats the best battery you can get?
<mvaenskae> DocScrutinizer05: what sim format are you incorporating btw?
<mvaenskae> edwin1: if you get a custom enclousure you should be able to fit in a larger battery i reckon; the n900 had some large batteries with extra covers; maybe you can procur one of those somewhere
raccoon_ has quit [Changing host]
raccoon_ has joined #neo900
<DocScrutinizer05> edwin1: unless you use a mugen battery cover, you hardly will find a better battery fitting in
<DocScrutinizer05> mvaenskae: ((SIM)) the original one of course :-)
mvaenskae has quit [Ping timeout: 255 seconds]
<edwin1> hmm I don't suppose you'll have much control on how (often) the modem scans/switches between networks? whenever I'm in roaming my battery life is very bad and it is switching networks quite often
starseeker has joined #neo900
<edwin1> as long as I'm not in a call I wouldn't care if it keeps the same network I'm already registered on even if it has 1 "bar"s strenght and the other one would have 3
<DocScrutinizer05> well, no, not much control of how modem works, except the usual selection of "band" (aka 2G/3G/LTE)
<DocScrutinizer05> and yes, modem searching for 3G stations all the time, while in a region with poor coverage and only a 2G station available, that costs some battery. You however can select "2G only" in that case
<DocScrutinizer05> starseeker: welcome! thanks for your interest in CAD (spacerframe), and Neo900 in general! :-)
<kerio> wait, how's 1320mAh the battery
jonwil has joined #neo900
<DocScrutinizer05> huh?
<kerio> aren't they ~1500 nowadays?
<DocScrutinizer05> whatever they are
<DocScrutinizer05> it's BL-5J formfactor
<edwin1> ebay says there is a 2500mAh, photo has a bunch of chinese writing on it so I can't tell if its a fake
<kerio> that one's a fake
<starseeker> DocScrutinizer05: thanks!
<DocScrutinizer05> HAH! I just unboxed that 50 bucks "huge set of spare parts for N900" from ebay. One of the 5 batteries is a Polarcell
<kerio> yay :3
<DocScrutinizer05> fair deal, indeed
<DocScrutinizer05> (the set)
<edwin1> hmm I was thinking that I could use something like airplane mode to save battery during times of day I don't want to receive calls anyway (i.e. deep asleep), but it would be annoying having to re-enter the PIN code every morning. Is there some mode that saves power on the modem (almost off but not quite) and doesn't require to re-enter a PIN to come out of it?
Pali has quit [Remote host closed the connection]
<DocScrutinizer05> on N900 you don't have to enter PIN after airplane->normal
<DocScrutinizer05> can even be scheduled by e.g. alarmed app
<edwin1> cool, one more reason to look forward for Neo900 then :)
<DocScrutinizer05> nonetheless you usually want to use the time while you're sleeping to charge the phone, not to let it sit and idle, saving some battery by going airplane-mode ;-)
<edwin1> yeah I usually do, but not everyday
<DocScrutinizer05> you must be using a featurephone :-)
<DocScrutinizer05> none of the smartphone users I know would think of not charging their device at least once a day
<edwin1> well tbh I don't use my phone that much (HTC Hero), the software is outdated, the applications I would want to run slow so I'm just waiting for something better to buy. meantime I use (and discharge a lot) my tablet
<kerio> i survive with charging my n900 once every two days
<DocScrutinizer05> actually N900 can stay idle (even with online mode) for several days, given you shut down all services that need internet connectivity, or you use WLAN for that
<edwin1> if WiFi is on then its true it doesn't last much more than a day
<DocScrutinizer05> N900 with wifi and IRC on survives much more than a day
<DocScrutinizer05> N900 with Wifi and only a ssh but no IRC survives almost a week
<DocScrutinizer05> (only on decent WLAN AP that supports PSM)
<edwin1> thats quite decent
<DocScrutinizer05> yes
<edwin1> is the modem/CPU separation going to help in terms of battery life?
<DocScrutinizer05> and it's always 'active' during that, means even via WLAN you can send commands and receive STDOUT any time, without lag
<edwin1> I mean can you put the CPU in a deeper sleep state than on other SoCs where modem integration is more tight?
<DocScrutinizer05> hmm, in terms of battery usage the separation is prolly irrelevant
<edwin1> does the CPU have to stay on?
<DocScrutinizer05> with a tendency to rather be a disadvantage
<edwin1> or can it just wake like every second or so to check for calls?
<DocScrutinizer05> the CPU on N900 is in zeroclock aka stop mode 99% of the time
<edwin1> ah ok, can it be like that in neo900 too?
<DocScrutinizer05> that's the 2trick" of maemo
<DocScrutinizer05> s/2/"/
<DocScrutinizer05> of course, Neo900 will work exactly same way
<edwin1> nice. I should probably read up on the features of N900 to get a better idea of what Neo900 be like. Never used a phone with maemo, it was featurephones and then android for me
<DocScrutinizer05> actually that's been one of the main arguments why we stay compatible to N900 so we can use maemo and profit from the awesome energy savings measures
chainsawbike has quit [Quit: yep... i broke it good that time...]
chainsawbike has joined #neo900
<edwin1> eh, I hope I'll still be able to dual-boot it with whatever else is compatible if there is enough room
<edwin1> can you boot from eMMC or only NAND?
<DocScrutinizer05> unlike virually any other phone OS, maemo allows true multitasking and always active, thanks to OMAP's bunch of power saving measures called "SmartReflex" which don't need any suspending of CPU
<DocScrutinizer05> we will configure the device to boot from all sources that make any sense, so of course also eMMC and uSD
<DocScrutinizer05> and of course you can multiboot as many OS flavors as you manage to put on the device
phre4k has joined #neo900
<edwin1> 512 MB NAND + 64 GB eMMC + external <- I don't know much about eMMC, but is that 64GB the maximum capacity supported, or will it actually ship as such?
<DocScrutinizer05> (which should be quite a few, with a at very least 32GB of eMMC)
<DocScrutinizer05> eMMC is soldered to the device, and we'll go for the maximum feasible and reasonable at time of production
<DocScrutinizer05> prolly 64GB
<kerio> why the NAND?
<DocScrutinizer05> why not?
<DocScrutinizer05> it seems there are few PoP chips that come without NAND anyway
<edwin1> so will the NAND hold things like the bootloader, recovery (thinking in terms of android don't know about maemo), efs and the eMMC the OS and data?
quatrox has joined #neo900
<DocScrutinizer05> up to you
<kerio> surely it'll hold the bootloader
<DocScrutinizer05> surely it will hold *one* bootloader, initially
<kerio> can ROMBL boot from something else
<DocScrutinizer05> you're free to place the bootloader to eMMC or uSD and nuke the one on NAND
<DocScrutinizer05> yes
<quatrox> Hello guys. Is it too late to make a donation for securing a device?
<kerio> neat
<DocScrutinizer05> quatrox: not at all
<quatrox> Perfect
<DocScrutinizer05> however note that we're about to change the minimum amount we need, since we already start sourcing components
<DocScrutinizer05> IOW you should already consider a higher down payment than 100
<edwin1> could you recommend some resources (wiki, forum, etc.) that describe how N900/Maemo is different from Android (like this trick with power saving you mentioned). I mean is there a 'Introduction to maemo for android converts'? :)
<DocScrutinizer05> we plan to source the 1GB RAM chips, some LEDs, and a few more chips and parts that might be tricky to source during short time when production finally starts
<DocScrutinizer05> edwin1: I'm afraid nothing really good like this is avalable
<DocScrutinizer05> generally talk.maemo.org and wiki.maemo.org are nice places to browse
<edwin1> k
<DocScrutinizer05> I guess a /join #maemo will be the right thing to do, when you want to learn about maemo
<DocScrutinizer05> then just ask, they are usually a nice bunch, unless you picked a time of day where just some few trolls are active
<edwin1> good point, will wait until I have a device to try it out on though
<quatrox> DocScrutinizer05: How much should I donate now in order to secure a complete device? 300 Euro or more?
<DocScrutinizer05> 300 sounds pretty good :-)
<DocScrutinizer05> actually "complete device" means we also want to source the "mech" parts like case, slider, LCD and so on. which will add another 100EUR on our own bill of materials
SylvieLorxu has quit [Ping timeout: 245 seconds]
<DocScrutinizer05> unless you have a N900 to do the mainboard swap
<DocScrutinizer05> in which case you don't need all those mech parts
<edwin1> what technology is used for screen dimming? my galaxy tab 3 seems to use some PWM that hurts my eye when brightness is on auto setting or when running very low on battery. Some LED monitor manufacturers advertise flicker-free (e.g. Benq), but I don't know if any of the smartphone touchscreens have that, or what N900 has.
<edwin1> if its PWM can it be made high-enough frequency so I don't notice it?
<DocScrutinizer05> I don't know what makes your eyes hurt
<edwin1> the flicker is quite visible, I'd guess 10-20 Hz or so
<DocScrutinizer05> actually I don't know the frequency the PWM is done, would be interesting to check that
<edwin1> but only on my tablet
<DocScrutinizer05> (it's done by the LCD controller chip)
<edwin1> that old phone is fine
<edwin1> also another tablet (iPad2) is fine too
<DocScrutinizer05> I guess that 20Hz must be a hw defect
<DocScrutinizer05> some LED drivers sometimes have that problem of getting instable and thus oscillating aka flickering
<edwin1> hmm will have to use this technique to measure the real frequency on the tablet http://www.tftcentral.co.uk/articles/pulse_width_modulation.htm
<edwin1> anyway as long as this didn't bother you on N900 hopefully Neo900 won't have this problem either
<edwin1> thanks for the answers, bye

<wpwrak> (if you have ImageMagick installed)
<DocScrutinizer05> >>Specify 'file' as '-' for standard input or output.<< \o/
<DocScrutinizer05> seems I have ;-)
<kerio> you need to specify the format if you're using stdio
SylvieLorxu has joined #neo900
<DocScrutinizer05> yeah, bmp:-
<sixwheeledbeast> gimp and export?
<DocScrutinizer05> wpwrak: GRRR! >>convert: length and filesize do not match `/tmp/magick-11019tWIV80bfOUC8' @ warning/bmp.c/ReadBMPImage/821.<<
<DocScrutinizer05> the extra byte
<DocScrutinizer05> umm
<DocScrutinizer05> echo ':disp:data?' | netcat 192.168.4.52 5555 | dd bs=1M iflag=skip_bytes skip=11 | convert bmp:- $1
<DocScrutinizer05> ignoring the warning, it makes for a nice tool to write arbitrary picture formats
<DocScrutinizer05> anyway, bbl
<DocScrutinizer05> o/
<DocScrutinizer05> I finally might want to teach dd to copy one byte less
<DocScrutinizer05> shouldn't be too hard since I'm already cheating with header length assuming it's fix, so I also can assume file size to be fix
<DocScrutinizer05> just need to tell dd to copy 1152056 Bytes instead of 1152057 Bytes
<DocScrutinizer05> err, actually itr seems it's THREE bytes too long?
<kerio> DocScrutinizer05: head -c -1
<DocScrutinizer05> :-D
<kerio> it could be a gnu thing however
<kerio> it doesn't work on bsd
<DocScrutinizer05> no bsd here

<kerio> ._.
<kerio> tail -c 11?
<kerio> er, -11
<DocScrutinizer05> could do that, yes
<kerio> dd is so non-unixy
<DocScrutinizer05> is it?
<kerio> options are ass
<kerio> it displays shit when nothing has gone wrong
<DocScrutinizer05> kerio: http://privatepaste.com/346b928893
<kerio> ?
<DocScrutinizer05> :-)
<kerio> oic
<kerio> you've literally spent more CPU time of your brain thinking about this optimization that you will EVER gain
<DocScrutinizer05> it's not meant to optimize CPU time :-)
<DocScrutinizer05> but it conventiemtly gets rif of said display shit ;)
<DocScrutinizer05> conveniently gets rid
<DocScrutinizer05> though I kinda liked that "shit"
<DocScrutinizer05> but now that it's evaluated and works and I know the scope is 3 times as fast when in STOP mode, I prolly don't have a use for it anymore
<DocScrutinizer05> cya peeps, time to check if the huricane blew away Nuremberg
