2014-01-24 14:12 <whitequark> okay, the cnc has arrived
2014-01-24 14:13 <wpwrak> i pity your neighbours
2014-01-24 14:14 <whitequark> hm, why?
2014-01-24 14:14 <wpwrak> you don't expect it to be silent, do you ? :)
2014-01-24 14:14 <whitequark> well, those fuckers just *love* to drill some walls when I'm trying to sleep
2014-01-24 14:15 <wpwrak> and at, say, 4 am, sound carries far ...
2014-01-24 14:15 <whitequark> so, let them suffer
2014-01-24 14:15 <whitequark> (it goes without saying that I don't necessarily try to sleep at night)
2014-01-24 14:15 <wpwrak> hint: you get the best sound effects when milling aluminium. since it's not self-lubricating, it will screech ...
2014-01-24 14:16 <wpwrak> yes, i took that into consideration :)
2014-01-24 14:16 <whitequark> unfortunately, there's some $work to do before I can play with it...
2014-01-24 14:17 <wpwrak> to avoid turning my friendly neighbours into mortal enemies, i constructed a double-walled box for my mill, with foam between the walls. that keeps moderate amounts of noise in quite well.
2014-01-24 14:18 <wpwrak> good enough for pcbs, acrylic, mdf, wood, and such.
2014-01-24 14:18 <nicksydney> after 2 days of troubleshooting 555 issue the problem lies in with the IC
2014-01-24 14:18 <whitequark> mmhm. on the serious note, the walls here are not *that* bad. if you're not drilling the wall directly, it's not really loud
2014-01-24 14:18 <whitequark> not annoyingly loud
2014-01-24 14:18 <wpwrak> you'd probably still hear the mill's pitiful screaming is it works it way through aluminium, though. my mill isn't very strong, so it has to go very slow for Al.
2014-01-24 14:19 <nicksydney> lesson learned : make sure you have *ENOUGH* of component that you are using for your project in hand !!!!
2014-01-24 14:19 <wpwrak> nicksydney: did you overcook it ? :)
2014-01-24 14:19 <whitequark> wpwrak: are houses in Argentina also made of cardboard, like they do in US for some weird reason?
2014-01-24 14:19 <wpwrak> and yes, that's why i always buy something like 10 at a time ;-)
2014-01-24 14:20 <nicksydney> wpwrak: i think so.....i remembered for some reason i was testing it with a mobile phone power supply (5v , 800ma) to use it on the breadboard...as i don't have enough batter lying around !
2014-01-24 14:20 <nicksydney> when it flash man !! I feel so exposed ! :)
2014-01-24 14:21 <wpwrak> whitequark: the walls are reasonable. not medieval fortress-style, but okay. hollow bricks for interior walls. the sound may not get that much through the walls but through other openings. isolation isn't a very high priority around here.
2014-01-24 14:21 <wpwrak> ;-)
2014-01-24 14:21 <whitequark> ahh, I see. I can say that, say, screams of children are appropriately attenuated
2014-01-24 14:22 <whitequark> okay, that sounded a little bit more weird than I wanted it to
2014-01-24 14:23 <whitequark> anyway, we'll learn soon enough. if there's an angry crowd and a battering ram at my door, I need to invest in soundproofing
2014-01-24 14:24 <wpwrak> i guess the adult dissidents are more of a nuisance. stronger lungs and lower frequencies ...
2014-01-24 14:24 <nicksydney> wpwrak: LED flashing http://videopasteus.s3.amazonaws.com/videos/21b3f11afd864c1fb0f736baca430dc1.html :)
2014-01-24 14:24 <whitequark> hehe
2014-01-24 14:25 <wpwrak> very 1970es ;-)
2014-01-24 14:25 <wpwrak> next step: use an MCU instead
2014-01-24 14:25 <nicksydney> wpwrak: i got the KL chip too ;)
2014-01-24 14:26 <nicksydney> next step is to make the PCB for the police siren with 2 x 555 timer
2014-01-24 14:27 <wpwrak> i'd skip the 555. it's too obsolete. you don't learn anything useful with it.
2014-01-24 14:27 <nicksydney> wpwrak: should i just jump to KL chip ?
2014-01-24 14:28 <wpwrak> you could make a little development board with the kl25. have a few leds, some headers, usb, and use the frdm-kl25z for programming
2014-01-24 14:28 <nicksydney> these 2 days really thought me something ... multimeter does not tell you the problem it can help you to detect voltage and current but it does not "show" you what wave pattern the voltage is in
2014-01-24 14:28 <wpwrak> (i hope you got the latter to work now)
2014-01-24 14:28 <nicksydney> damn it! haven't done the kl25z upgrade using Windows ....crap !
2014-01-24 14:28 <wpwrak> (wave pattern) now, miracles not included ;-)
2014-01-24 14:28 <wpwrak> hah ! :)
2014-01-24 14:29 <nicksydney> if i have used a scope perhaps i could have seen that it is not giving out any wave pattern .. so at least i know it was a screwy IC
2014-01-24 14:33 <nicksydney> wpwrak: i don't understand why doesn't freescale provide flashing using USB ?
2014-01-24 14:33 <wpwrak> you'll need a scope in the longer run. better plan on getting one. and don't look at the ultra-cheap ones. they're just trouble.
2014-01-24 14:33 <nicksydney> like Atmel
2014-01-24 14:33 <nicksydney> wpwrak: i'm saving for one...hopefully will save around $400 in the next 2-3months time
2014-01-24 14:34 <wpwrak> (flashing via usb) dunno. the chips would certainly be in a range where such a feature could be expected. maybe they'll add it in the future.
2014-01-24 14:35 <wpwrak> the frdm-kl25z is actually quite nice once you get it to work. the file-based interface avoids all the trouble with drivers. their only (big) mistake was to not care about linux compatibility right from the beginning.
2014-01-24 14:36 <nicksydney> wpwrak: so if i didn't have the kl25z board and i design a board with the KL chip how do one go about flashing it then ?
2014-01-24 14:38 <wpwrak> you'd have to cook up an SWD solution with openocd and such. this promises to be messy. i wouldn't go that route.
2014-01-24 14:39 <whitequark> openocd's swd support is meh
2014-01-24 14:39 <wpwrak> i'd get the frdm board to work, then either use that all the time or make a dfu loader and work with this
2014-01-24 14:39 <wpwrak> exactly :)
2014-01-24 14:39 <wpwrak> it exists but it's a mess
2014-01-24 14:40 <nicksydney> what is a dfu loader ? it's a bootloader ?
2014-01-24 14:40 <wpwrak> what i've seen regarding swd has convinced me that it should be possible to piece an open solution together but that it would be a piece of work
2014-01-24 14:41 <wpwrak> dfu is a transfer protocol, not too unlike tftp. it's very simple, designed for firmware uploads. it's also what atmel, stm, etc. generally use.
2014-01-24 14:42 <wpwrak> i haven't made a loader for the kl25 just yet, but more or less all the code for it is around from ben-wpan
2014-01-24 14:42 <wpwrak> e.g., the new y-box will get a dfu loader
2014-01-24 14:44 <wpwrak> (scope) if you want rock bottom pricing, a rigol ds1052e or ds1102e will be a good choice (USD 329-399)
2014-01-24 14:45 <wpwrak> if you can spend a little more, i'd go for the ds1074z (usd 585). it has four channels, which will be very handy at times. and some other advanced features as well. probably has the best price/performance ratio in today's market.
2014-01-24 14:45 <nicksydney> wpwrak: i think that price range is suitable for someone like me :)
2014-01-24 14:46 <nicksydney> ($585) if i have to spend this much then i will need at least 4-5 months to save first :)
2014-01-24 14:47 <wpwrak> tell the wife to go easy on the shoes for a while ;-)
2014-01-24 14:47 <nicksydney> http://dfu-programmer.sourceforge.net/
2014-01-24 14:47 <nicksydney> wpwrak: haha.....I wish that's the case but here down under the biggest expense is living cost...it's F***** crazy expensive here !!
2014-01-24 14:48 <wpwrak> or this one: http://dfu-util.gnumonks.org/
2014-01-24 14:49 <wpwrak> (cost living) probably all the glue ... the glue you need that you don't fall off the earth :)
2014-01-24 14:51 <whitequark> dfu-util++
2014-01-24 14:52 <nicksydney> so in order to 'download' to the device the device must be running an 'app' or 'daemon' that is listening to USB ?
2014-01-24 14:54 <wpwrak> yes, it must run either the dfu loader or a usb stack that can switch to the dfu loader
2014-01-24 14:54 <whitequark> it needs a stub in the application which would transfer it to DFU mode, and a DFU bootloader
2014-01-24 14:55 <whitequark> usually the loader is separate to make it more robust
2014-01-24 14:55 <wpwrak> what i do is that i run a dfu-only boot loader first for maybe 2 seconds.if nobody tries to talk to it, then it jumps to the application
2014-01-24 14:55 <wpwrak> that way, if the application is broken, you can still dfu
2014-01-24 14:56 <wpwrak> you can see the whole architecture in ben-wpan/atusb/fw/
2014-01-24 14:56 <nicksydney> wpwrak: thanks will read it
2014-01-24 15:03 <wpwrak> note that boot loader and application are really two separate programs, although they share a lot of code
2014-01-24 15:04 <nicksydney> understood :)
2014-01-24 16:01 <whitequark> HAHAHAHAHA
2014-01-24 16:01 <whitequark> this chinese power supply has an excellent manual
2014-01-24 16:01 <whitequark> quoting: " power supply are not allow at full load state for long time. control your utilization rate of less than 60%, or they may cause human early failure"
2014-01-24 16:05 <lekernel> submit it to http://engrish.com/ :)
2014-01-24 16:06 <wpwrak> brilliant :)
2014-01-24 16:08 <wpwrak> reminds me a bit of the owner's manual of the alfa romeo i had in switzerland. it said something like "do not drive at excessive speed for prolonged time"
2014-01-24 16:09 <wpwrak> i have to admit that the car, small as it was, was perfectly capable of doing just that :)
2014-01-24 16:17 <whitequark> the box has really creative packaging
2014-01-24 16:17 <roh> whitequark: i once had a manual which sayd something like 'if there is conflict between reality and manual, please give priority to reality'
2014-01-24 16:17 <whitequark> they take polyethylene packages and inflate them with polyurethane assembly foam
2014-01-24 16:17 <whitequark> roh: hehehe. that's some good advice, you must admit!
2014-01-24 16:18 <wpwrak> roh: that's what you get when you hire philosophy students for your documentation department ;-)
2014-01-24 16:19 <roh> i found that really sane. compared to other manuals.

2014-01-24 16:36 <whitequark> instructions for assembly... not included?
2014-01-24 16:36 <whitequark> except maybe they're on the CD-R. CD-R, LPT, PRC is certainly not on a forefront of technological innovation
2014-01-24 16:36 <whitequark> do I even have anything to read it with.
2014-01-24 16:38 <whitequark> "comes with a two year warranty" now that's neat!
2014-01-24 16:41 <whitequark> I actually know what this reminds me about. USSR. sturdy, absolutely massive (both literally and figuratively) machinery with solid repairability and "some assembly requirements"
2014-01-24 16:41 <whitequark> it even looks that way
2014-01-24 16:42 <whitequark> well, it's not really surprising
2014-01-24 16:43 <whitequark> lol no. the CD only includes a pirated version of MACH3 CNC control software

2014-01-24 17:03 <whitequark> the control block is rated 110-120VAC.
2014-01-24 17:03 * whitequark sighs
2014-01-24 17:05 <wpwrak> it runs directly off mains ?
2014-01-24 17:05 <larsc> nothing you can't slove with a bunch of copper wire and two sticks ;)
2014-01-24 17:06 <whitequark> well, it includes the stepper drivers
2014-01-24 17:06 <whitequark> s
2014-01-24 17:06 <whitequark> and looking at how they're still with LPT, I have this suspicion they haven't discovered switch-mode power supplies yet
2014-01-24 17:07 <wpwrak> do they already use valves ? or is it still relays ? :)
2014-01-24 17:08 <whitequark> haven't disassembled it yet
2014-01-24 17:16 <whitequark> yeah, it contains an enormous transformer. input; 110V 50HZ; output: 18V white 36V yellow
2014-01-24 17:16 <whitequark> and it is truly enormous, the damn thing weights, I think, about 3kg
2014-01-24 17:18 <whitequark> yeah, 3100 g
2014-01-24 17:21 <wpwrak> now you need another 3 kg 220 V to 110 V transformer ;-)
2014-01-24 17:22 <whitequark> yeah I'll try to find one. might be tricky.
2014-01-24 17:22 <wpwrak> really ?
2014-01-24 17:22 <whitequark> I'll also contact the vendor, they seem to present themselves as extremely helpful. time to check that!
2014-01-24 17:22 <whitequark> (tricky) yeah, why would people want such transformers?
2014-01-24 17:23 <whitequark> 99% of electronics already supports 110-240V, because they're not living in the damn 19th century
2014-01-24 17:23 <whitequark> and the rest is localized and sold in variants
2014-01-24 17:24 <DocScrutinizer05> whitequark: you finally received your CNC?
2014-01-24 17:24 <wpwrak> still. there's always the odd 110 V item. even modern products.
2014-01-24 17:24 <whitequark> DocScrutinizer05: yeah
2014-01-24 17:24 <whitequark> and it's rated 110V :/
2014-01-24 17:24 <whitequark> and it has a fucking transformer

2014-01-24 17:25 <wpwrak> would you have preferred resistors ? :-)
2014-01-24 17:25 <whitequark> lol
2014-01-24 17:25 <DocScrutinizer05> check transformer, it may have a 220V setting
2014-01-24 17:25 <whitequark> no, already disassembled it. clearly rated as 110V only on the label
2014-01-24 17:25 <DocScrutinizer05> dang!
2014-01-24 17:26 <wpwrak> maybe there's a 9 V output ? then you could apply chinese pragmatism :)
2014-01-24 17:26 <DocScrutinizer05> you are in for a 220->110 converter then
2014-01-24 17:26 <whitequark> (9V output) nah
2014-01-24 17:26 <whitequark> thought about it already ;)
2014-01-24 17:27 <DocScrutinizer05> find any 220V transformer that consists of 2 times 110V primary coils
2014-01-24 17:27 <DocScrutinizer05> and is heavy enough
2014-01-24 17:28 <whitequark> welp, I don't really collect antique power supplies
2014-01-24 17:28 <whitequark> anything I might have is strictly switch-mode
2014-01-24 17:28 <DocScrutinizer05> connect it o--110V-^-110V-^-o
2014-01-24 17:28 <whitequark> I have one adjustable power supply, but this thing needs 36V and 18V
2014-01-24 17:28 <DocScrutinizer05> where "o" are your 220V mains, and "^" is your CNC
2014-01-24 17:28 <whitequark> and this one only goes up to 27V anyway
2014-01-24 17:29 <whitequark> yeah I understand how transformers work :p
2014-01-24 17:29 <DocScrutinizer05> :-)
2014-01-24 17:29 <DocScrutinizer05> this is a special way though
2014-01-24 17:29 <wpwrak> in the good old days, you'd just have connected it to 220 V or whatever, and it would have worked :)
2014-01-24 17:30 <whitequark> by the way, the insides have some veeeery interesting exposed and labeled pads
2014-01-24 17:30 <DocScrutinizer05> http://commons.wikimedia.org/wiki/File:Auto_transformer.png
2014-01-24 17:30 <whitequark> "PWM" "STOP" "SW1" for the spindle board
2014-01-24 17:30 <whitequark> "CP+- DIR+- LIMIT" for the stepper board
2014-01-24 17:31 <whitequark> also "PROBE", whatever that is
2014-01-24 17:31 <whitequark> there's even some holes tucked with plastic in the case
2014-01-24 17:31 <DocScrutinizer05> http://ru.wiktionary.org/wiki/автотрансформатор
2014-01-24 17:31 <whitequark> DocScrutinizer05: yep, I know
2014-01-24 17:31 <whitequark> it's a pretty funny mode of operation
2014-01-24 17:32 <DocScrutinizer05> yeah, for others nevertheless: http://de.wikipedia.org/wiki/Spartransformator
2014-01-24 17:32 <whitequark> http://en.wikipedia.org/wiki/Autotransformer :)
2014-01-24 17:32 <whitequark> I don't really use ru.wiki, it sucks
2014-01-24 17:35 <DocScrutinizer05> looks like
2014-01-24 17:37 <DocScrutinizer05> what usually isn't considered though: each transformer with more than one primary coil can get used as a autotransformer. Actually since there's no difference between priimary and secondary coils you can use every transformer as a autotransformer ;-)

2014-01-24 17:40 <whitequark> wow: http://www.avito.ru/moskva/kollektsionirovanie/avtotransformator_karbolit_sssr_1958_g_184948538
2014-01-24 17:40 <whitequark> this is literally antique: 1958!
2014-01-24 17:57 <whitequark> ok, asked the vendor for the 220V control box. let's wait...
2014-01-24 18:15 <DocScrutinizer05> you're sure the transformer has no 220V tap?
2014-01-24 18:17 <whitequark> well, it's tightly wrapped in some plastic crap, and there aren't any unconnected wires
2014-01-24 18:17 <whitequark> I'd rather not unwrap it
2014-01-24 18:33 <DocScrutinizer05> no wires -> no tap
2014-01-24 18:34 <DocScrutinizer05> a pity
2014-01-24 18:35 <DocScrutinizer05> I guess the priimary coil isn't built to cope with 220V and you simply use a different secondary voltage/tap
2014-01-24 18:35 <whitequark> likely
2014-01-24 18:35 <DocScrutinizer05> fools
2014-01-24 18:36 <DocScrutinizer05> I bet they will offer to send you a 220->110 converter
2014-01-24 18:36 <DocScrutinizer05> or refund you for purchasing one
2014-01-24 18:36 <whitequark> either one is fine for me
2014-01-24 18:37 <DocScrutinizer05> asia?
2014-01-24 18:37 <whitequark> they send from US, but, yeah, china
2014-01-24 18:37 <DocScrutinizer05> then they for sure don't want you to send back the wrong controlbox
2014-01-24 18:38 <whitequark> that would be bloody expensive, shipping back 3kg of metal
2014-01-24 18:38 <whitequark> I've spent almost half of the cost of the CNC getting it to russia
2014-01-24 18:38 <DocScrutinizer05> get a autotransformer from next surplus store, and offer them to pay a refund
2014-01-24 18:39 <DocScrutinizer05> such transformer converter is useful for other stuff as well
2014-01-24 18:39 <DocScrutinizer05> ;-)
2014-01-24 18:39 <whitequark> well, I have a bunch of other stuff with 110V plug, but you see, I just pop it into my 220V mains and it works
2014-01-24 18:40 <whitequark> because switchmode supplies are so. fucking. awesome.
2014-01-24 18:40 <DocScrutinizer05> and the heck, Russia for sure has the best most rugged converter transformers you could possibly find in this universe
2014-01-24 18:40 <whitequark> there's basically three options for that
2014-01-24 18:40 <whitequark> 1) LATR, laboratory autotransformer. kinda expensive and I don't really need adjustable output voltage
2014-01-24 18:41 <whitequark> altohugh maybe I could find some other use for it...
2014-01-24 18:41 <whitequark> 2) antique soviet transformers. I'm sure they were fine when they were first made, but I'm wary of buying 40+ year old stuff stored in unknown conditions (likely just outside in the cold, at least for some time) and plugging it into mains
2014-01-24 18:42 <whitequark> 3) some new ones. also expensive and there isn't a lot of options.
2014-01-24 18:42 <DocScrutinizer05> no worries, transformers are a rare case of "lasts forever"
2014-01-24 18:43 <whitequark> mhm

2014-01-24 18:44 <DocScrutinizer05> worst thing to happen is when isolation of the connect wires gets brittle
2014-01-24 18:44 <whitequark> this one seems kinda fine
2014-01-24 18:44 <whitequark> 630W
2014-01-24 18:44 <DocScrutinizer05> even a ring core
2014-01-24 18:45 <whitequark> for $20
2014-01-24 18:45 <DocScrutinizer05> cool
2014-01-24 18:45 <DocScrutinizer05> get it
2014-01-24 18:45 <whitequark> okay
2014-01-24 18:45 <whitequark> this solves the problem, yeah

2014-01-24 19:14 <whitequark> okay, I'm trying to understand how this adjustable power supply works
2014-01-24 19:14 <whitequark> it has constant voltage and constant current modes
2014-01-24 19:14 <whitequark> but the manual is completely incomprehensible
2014-01-24 19:19 <whitequark> ah, it's simple. when the current is less than setpoint, it's in constant voltage mode. when it's equal, it's in constant current one.

2014-01-24 21:44 <DocScrutinizer05> DAMN! this fuji XQ1.... acts like a AP. Which tricked me into turning my AP into a client X-S
2014-01-24 21:44 <DocScrutinizer05> wonder how I could make the camera act as second AP via USB ;-P
2014-01-24 21:48 <DocScrutinizer05> could anybody with a damn android or iPhone (or even windows) check what IP traffic these friggin apps ( http://app.fujifilm-dsc.com/de/pc_autosave/index.html et al) create to talk to camera?
2014-01-24 21:49 <whitequark> um, I have windows and android
2014-01-24 21:49 <DocScrutinizer05> http://app.fujifilm-dsc.com/de/camera_app/index.html
2014-01-24 21:49 <whitequark> what exactly do you want?
2014-01-24 21:49 <whitequark> I don't have your camera
2014-01-24 21:50 <DocScrutinizer05> the app pings the camera somehow
2014-01-24 21:50 <whitequark> mhm
2014-01-24 21:50 <DocScrutinizer05> or opens a port and listens, at least
2014-01-24 21:50 <whitequark> pc_autosave thing is the PC one?
2014-01-24 21:50 <whitequark> well, dumb question
2014-01-24 21:50 <DocScrutinizer05> yep, I guess
2014-01-24 21:51 <whitequark> ok, I'll check in a virtualbox
2014-01-24 21:51 <DocScrutinizer05> when I start "wireless" on camera, it tells me to "start app on PC!"
2014-01-24 21:51 <DocScrutinizer05> camera acts as a AP
2014-01-24 21:51 <DocScrutinizer05> :-o
2014-01-24 21:52 <DocScrutinizer05> I made it "connect" to another AP nevertheless, so in some cases it seems to act as wlan client
2014-01-24 21:52 <DocScrutinizer05> but it doesn't talk
2014-01-24 21:52 <DocScrutinizer05> neither does it show up in DHCP
2014-01-24 21:52 <DocScrutinizer05> so I guess the damn PC-app is semding a broacast
2014-01-24 21:53 <DocScrutinizer05> I bet once it got associated and has an IP, I can talk pictbridge or even ftp to it
2014-01-24 21:54 <DocScrutinizer05> I have no WLAN stick for my PC, otherwise I'd fire it up and snoop on it with wireshark or even airodump
2014-01-24 21:55 <DocScrutinizer05> aunt google knows shit about XQ1 WLAN protocol
2014-01-24 21:56 <DocScrutinizer05> my N900 detected AP as "Fuji-XQ1" AP without any encryption
2014-01-24 21:56 <whitequark> iw phy phy0 interface add mon0 type monitor
2014-01-24 21:56 <whitequark> wireshark -i mon0
2014-01-24 21:56 <whitequark> that's all you need
2014-01-24 21:56 <DocScrutinizer05> "Fuji-XQ1" been the name I assigned to the cam in on-board menu before
2014-01-24 21:57 <DocScrutinizer05> whitequark: you're talking in tongues to me
2014-01-24 21:58 <whitequark> that's a command to create a monitor interface for an existing wlan phy
2014-01-24 21:58 <DocScrutinizer05> you think I could monitor the traffic on router's WLAN from my PC?
2014-01-24 21:58 <whitequark> if you have a wifi stick in it, yes
2014-01-24 21:58 <DocScrutinizer05> my PC *has* *no* WLAN
2014-01-24 21:59 <whitequark> yes, I just seen you metnion airodump
2014-01-24 21:59 <whitequark> and airodump is silly and I hate it, all it does is the iw command above
2014-01-24 21:59 <whitequark> that's all
2014-01-24 21:59 <DocScrutinizer05> [2014-01-24 22:54:30] <DocScrutinizer05> I have no WLAN stick for my PC, otherwise I'd fire it up and snoop on it with wireshark or even airodump
2014-01-24 21:59 <whitequark> I just spent some hours figuring out how to invoke iw properly to add a monitor iface
2014-01-24 21:59 <whitequark> btw
2014-01-24 21:59 <whitequark> what's on your router?
2014-01-24 22:00 <whitequark> mine has openwrt
2014-01-24 22:00 <whitequark> so, yeah, would be totally possible to snoop on wlan
2014-01-24 22:00 <DocScrutinizer05> dd-wrt
2014-01-24 22:01 <whitequark> should be possible as well
2014-01-24 22:01 <whitequark> it either has a mon0 iface or you can create it with the command above
2014-01-24 22:01 <DocScrutinizer05> thanks for the tip about iw monitor
2014-01-24 22:01 <whitequark> then tcpdump it
2014-01-24 22:01 <whitequark> tcpdump is one hell of deceptively named software
2014-01-24 22:02 <DocScrutinizer05> :nod:
2014-01-24 22:02 <DocScrutinizer05> but that shell (and /bin/*) on that dd-wrt is a PITA
2014-01-24 22:02 <whitequark> well, coreutils weigh how much, 50MB?
2014-01-24 22:03 <DocScrutinizer05> I bet such stuff like tcpdump is pretty totally unknown to it
2014-01-24 22:03 <whitequark> hard to put on a 4MB squashfs
2014-01-24 22:03 <DocScrutinizer05> you think I can install them, from the errrr pinkpony-repo?
2014-01-24 22:03 <whitequark> (tcpdump) yep, busybox doesn't have a tcpdump, it's an external package
2014-01-24 22:03 <whitequark> in openwrt it's in the official repo
2014-01-24 22:03 <whitequark> dunno about ddwrt, but it seems like an obvious tool to provide
2014-01-24 22:04 <DocScrutinizer05> I don't even know of *any* repo to install additional stuff on that router
2014-01-24 22:05 <DocScrutinizer05> well, that camera has a diabolic potential to waste my time on totally irrelevant stuff
2014-01-24 22:05 <whitequark> hahaha
2014-01-24 22:05 <whitequark> http://emtunc.org/blog/04/2011/installing-tcpdump-on-dd-wrt-wrt54gl/
2014-01-24 22:05 <whitequark> tl;dr: install tcpdump from openwrt
2014-01-24 22:05 <DocScrutinizer05> mhm
2014-01-24 22:05 <whitequark> the comments are probably wrong for you
2014-01-24 22:06 <whitequark> what architecture it even is?
2014-01-24 22:06 <DocScrutinizer05> nfc
2014-01-24 22:06 <DocScrutinizer05> broadcom?
2014-01-24 22:06 <whitequark> no, cpu. mips?

2014-01-24 22:06 <DocScrutinizer05> hah
2014-01-24 22:06 <DocScrutinizer05> lemme see if I can manage to log in to the damn router
2014-01-24 22:07 <whitequark> ok, so, what I suggest for you is just download and unpack those two packages
2014-01-24 22:07 <whitequark> it's just dpkg, each with one file inside: libpcap and tcpdump itself
2014-01-24 22:07 <whitequark> then upload them anywhere on the router and set LD_LIBRARY_PATH and you're set
2014-01-24 22:08 <whitequark> don't even need to properly invoke ipkg. just put them to /tmp
2014-01-24 22:09 <DocScrutinizer05> saturn:/ # ssh root@192.168.4.1

2014-01-24 22:12 <DocScrutinizer05> I'll rather use my CF-27 anti-tank-mine to connect to the XQ1 directly
2014-01-24 22:12 <whitequark> lol
2014-01-24 22:12 <whitequark> oh, not a literal anti-tank mine
2014-01-24 22:12 <whitequark> wouldn't be too surprised

2014-01-24 22:14 <whitequark> grab money, papers, toughbook, run ?
2014-01-24 22:14 <DocScrutinizer05> sth like that, yep
2014-01-24 22:14 <whitequark> you're living in germany. not libya. no?
2014-01-24 22:14 <DocScrutinizer05> the toughbook is an excellent weapon
2014-01-24 22:15 <DocScrutinizer05> catches bullets, crashes through everything you swing it against
2014-01-24 22:16 <DocScrutinizer05> you can sit on it
2014-01-24 22:16 <DocScrutinizer05> and even use it to communicate
2014-01-24 22:16 <whitequark> hehe
2014-01-24 22:16 <DocScrutinizer05> or watch maps etc
2014-01-24 22:17 <whitequark> ok, your fujicrap downloaded to my vm

2014-01-24 22:19 <whitequark> ugh, .NET framework

2014-01-24 22:25 <DocScrutinizer05> I guess if we could come up with a sane solution allowing to download pictures from the XQ1 via WLAN (maybe even use the "instant download to PC" function that's supposed to transfer each shot instantaneously to the PC after shooting), we could even *sell* that
2014-01-24 22:25 <whitequark> can you connect the camera to AP?

2014-01-24 22:25 <DocScrutinizer05> yes, seems like I can
2014-01-24 22:25 <whitequark> see, if the camera generates broadcast packets, you can watch them from your PC
2014-01-24 22:25 <whitequark> precisely because they're broadcast
2014-01-24 22:25 <whitequark> and now we know PC doesn't emit anything
2014-01-24 22:26 <DocScrutinizer05> there's the "PC download" mode that's supposed to do that
2014-01-24 22:26 <DocScrutinizer05> yes, will fire up wireshark to see if any broadcast inbound
2014-01-24 22:26 <whitequark> oooh a wild guess
2014-01-24 22:26 <whitequark> it uses SMB
2014-01-24 22:27 <whitequark> see, the connection screen displays the SMB hostname of the PC
2014-01-24 22:27 <whitequark> and SMB does the broadcast thing
2014-01-24 22:27 <whitequark> you might be able to set it up with samba

2014-01-24 23:30 <whitequark> huh, g-code is actually turing-complete
2014-01-24 23:30 <whitequark> I should write something insane in it
