[3:31] <zombieJesus> USB
[3:31] <ShorTie> from pc ??
[3:31] <zombieJesus> no, from power block
[3:32] <zombieJesus> I did something wrong I think maybe
[3:32] <mrkramps> no enough power i'd guess
[3:32] <ShorTie> does your cable have 24awg printed on it ??
[3:33] <zombieJesus> it has to be power related I think
[3:33] <zombieJesus> it happens when I plug in a USB stick
[3:33] <zombieJesus> boom, insta reboot
[3:33] <mrkramps> it is power related then
[3:33] <ShorTie> you can't beet those 5.25v@3amp supplies
[3:34] <zombieJesus> I'll copy the roms off usb and into /home/pi/retropi
[3:35] <ShorTie> it will help, but will not solve problem
[3:36] <mrkramps> which power block? model?
[3:37] <ShorTie> get 1 of these, http://www.ebay.com/itm/15-75W-5-25V-3A-AC-Adapter-Power-Charger-For-HP-Chromebook-11-2001tu-11-2081no-/152093436447?hash=item236979aa1f:g:Jl4AAOSw4GVYQPEF

[7:42] <thereyougo> what is the most powerful RPi model ? the one with 2GB ram and 4 cores ?
[7:42] <IanTLopp> there are none with 2gb
[7:42] <IanTLopp> but the raspi 3 B is the currently most powerful model
[7:42] <thereyougo> 1GB ?
[7:42] <IanTLopp> yes, 1gb
[7:43] <IanTLopp> there was an april fool's joke about the raspi 4, which had 2 GB, and other BS features.
[7:43] <thereyougo> why can't they make something with more RAM ? even average home PC now has 8GB of RAM
[7:43] <IanTLopp> $35
[7:44] <thereyougo> RAM is cheap nowadays
[7:44] <IanTLopp> the raspberry pi isn't an average pc... it's one of the least expensive project board/computers on the market
[7:44] <IanTLopp> not cheap enough
[7:44] <nevodka> size and price constraints
[7:44] <IanTLopp> $35 for everything that's on the Raspi 3 is INCREDIBLY good deal.
[7:44] <nevodka> look at odroid or other sbc's
[7:44] <nevodka> they are more expensive and have 2gb ram
[7:45] <thereyougo> or its very important to keep RPi's price about $35 ? isn't the main point of havin RPi is having it eat less power ? I mean if you make model say with 8GB it will not eat more power is it ?
[7:45] * SopaXorzTaker (~SopaXorzT@unaffiliated/sopaxorztaker) has joined #raspberrypi
[7:45] <IanTLopp> he could get one of the atom boards if he wants something "better" than a raspi for more money
[7:45] <thereyougo> how much do you think would it add to price if you make it with 8GB of ram ? $100 ?
[7:45] * sphenxes (~sphenxes@81-5-241-122.hdsl.highway.telekom.at) has joined #raspberrypi
[7:46] <nevodka> your assumptions are incorrect
[7:46] <IanTLopp> thereyougo: I can only speak as an innocent bystander here, but I'm pretty sure the price is a fairly major factor with regards to the raspi setup... if you want something more there are a LOT of other options out there, but the raspi isn't designed with super power in mind.
[7:47] <binaryhermit> another thing is the SoC only supports 1 GB of RAM
[7:48] <nevodka> the "main point" is an affordable computing device imo
[7:48] <thereyougo> what is the closest alterntive with say 4GB RAM and 4 CPU cores and small price ? odroid ?
[7:48] <nevodka> its not just a computer stripped of peripherals
[7:48] <thereyougo> alternative
[7:48] <IanTLopp> thereyougo: the biggest problem with most alternatives is the lack of support
[7:48] <IanTLopp> your best bet is probably one of the atom units.
[7:49] <IanTLopp> BUT, if you don't mind french, the bananapi's have some interesting options.

[7:51] <IanTLopp> thereyougo: another thought for you. what are you doing that makes you think you need more ram?
[7:52] <IanTLopp> not saying there's not a reason, but a lot of the time we just want bigger/better/whatever without realizing that if we streamline our ideas, we can have a better experience with a lower cost/more supported solution.

[8:04] <binaryhermit> no, it had 4 and 1 GB
[8:05] <thereyougo> because, for some reason people want more cores but not more RAM ? and if increasing number of cores made it more expensive we would still have 2 cores RPi ?

[8:53] <amigojapan> hi, so the only way to use controllers in RPI is using retropi? cant I use them under raspbian? I have an Xbox360 controller with USB adapter and a normal USB controller
[8:53] <nevodka> nobody says growing up is fun IanTLopp :-]
[8:53] <IanTLopp> NedScott: DAMN IT... halfway through I was thinking you were for real - thought maybe you had some advanced prediction algorithm you were working on... yeeesh

[8:53] <IanTLopp> amigojapan: sure you can :)
[8:53] <nevodka> its not fun for everyone :p
[8:54] <IanTLopp> amigojapan: it's just a driver issue - as long as the OS you're running has the proper drivers for Xbox 360 controllers, they should work fine.
[8:54] <IanTLopp> what are you trying to do that retropie won't work with?
[8:54] <amigojapan> IanTLopp: but raspbian does nto seem to have them with preinstalled settings
[8:55] <nevodka> so what? install it
[8:55] <amigojapan> IanTLopp: no, I dont want to use retropi I want to use raspbian
[8:55] <drjam> mmmm raspifun...soon to be released distro haha
[8:55] <amigojapan> nevodka: what is the name of the backage of hte drivers?
[8:55] <amigojapan> package*
[8:55] <IanTLopp> amigojapan: not saying it's bad to do so, but what do you want to do in raspbian with the controller?
[8:55] <nevodka> do you not have google
[8:56] <amigojapan> IanTLopp: emulation, I already have the emulator running, but it wotn recognize my controllers
[8:56] <NedScott> I thought RetroPie was just an installation script on top of Raspbian
[8:56] <nevodka> https://packages.debian.org/jessie/utils/xboxdrv
[8:57] <amigojapan> ty nevodka
[8:57] <NedScott> I think you can install the RetroPie installation script and tell it to only install controller support, and not any emulators
[8:57] <NedScott> just as a way to make it easy
[8:57] <NedScott> I also recall there being a driver for the 360 controller that will emulate keyboard input, so that it works in anything
[8:58] <IanTLopp> NedScott: mostly - but now it has its own entire package (which is retropie preinstalled on top of raspbian)
[8:58] <IanTLopp> amigojapan: again, not saying you're doing anything wrong, but why not use retropie for emulation as opposed to a separate emulator on raspbian?

[9:03] <amigojapan> IanTLopp: if I had easya ccess to the SD card, I would use retropi

[9:17] <NedScott> those are listed right in the warrantee
[9:17] <IanTLopp> so I unplugged it, and messed with a file or two, then plugged it back in. Did this several times.

[9:17] <drjam> happens
[9:17] <IanTLopp> but now after reinstalling OctoPi, the plugging in the raspi, no light comes on, AT ALL
[9:18] <IanTLopp> just put a different SD card in - still no light on the unit.

[11:02] * Mikelevel (~MoVeWoRk@unaffiliated/mikelevel) has joined #raspberrypi
[11:02] <IanTLopp> at a draw of 2.5amps I'm likely to get only 4 hours on this 10,000 mah battery
[11:03] <IanTLopp> anything less than 10,000 seems pointless, unless you're trying to emulate the nomad and it's infamous 30 minute battery
[11:04] <NedScott> you ever see the ODROID-W?
[11:05] <NedScott> the only true clone of a Pi, using the same Broadcom SoC (until Broadcom stopped selling them more chips)
[11:05] <NedScott> had a built-in lipo circuit
[11:05] <NedScott> it came out before the B+ did http://www.hardkernel.com/main/products/prdt_info.php?g_code=g140610189490
[11:06] <NedScott> so it doesn't have the 40 pin connector, but still a neat little guy
[11:06] * Tyklol is now known as Tykling
[11:07] <nacelle> i wouldnt worry about .1 amp on a pi3
[11:07] <nacelle> i've run my pi3 on a 2amp supply for over a year without issues until I start to plug in a lot of usb things
[11:08] <gordonDrogon> IanTLopp, the 2.5A is only needed with everything going flat-out and the USB+GPIO taking 1.2 amps too.
[11:08] <nacelle> (like a keyboard + usb game controller + hdmi monitor + ps3 controller == too much)
[11:08] <gordonDrogon> so you can take 1.2A off what's needed if not using usb or taking power off the gpio.
[11:08] <IanTLopp> gordonDrogon: except no... not really, because if I plug a 2.4amp charger into the pi3, when it turns on, I get a little yellow lightning icon in the top right and EVERYTHING is slowed down.
[11:09] <IanTLopp> can't even play snes games without major lag
[11:09] <mfa298> depending on what's plugged into the Pi, you might not need the 2.4A, the SoC itself is around 1.3A max
[11:09] <nacelle> IanTLopp: even with a 5v/3a supply you will see the lightning on boot time
[11:09] <IanTLopp> that is, of course, specifically running retropie.. perhaps other things wont' have that.
[11:09] <gordonDrogon> IanTLopp, that means it's not able to actually provide 5v at 1amp. mesure it. you have a somewhat sub-optimal PSU.
[11:09] <IanTLopp> nacelle: no... I have a 2.5a charger and the pi 3 boots up without the lightning icon, and nothing is slow.
[11:10] <mfa298> IanTLopp: also that 10Ah is probably the cell capacity (so at 3.7V, it'll be less at the 5v used by the Pi and you'll lose some in the boost circuit)
[11:10] <gordonDrogon> you have a box that says 2.5A on it.
[11:10] <nacelle> IanTLopp: nice
[11:10] <gordonDrogon> most of the cheap ones lie.
[11:10] <gordonDrogon> this is something we've learned over the 5+ years of Pi use )-:
[11:10] <gordonDrogon> some of the expensive ones lie too )-:
[11:11] <IanTLopp> gordonDrogon: this is an official raspi charger, and I also have a nonofficial raspi charger that are both at 2.5, both have the SAME function and provide the required powered to the pi 3... EVERY charger I have for every tablet, and every phone I've tried on the pi 3 all give the yellow lightning icon and slow down in SNES.
[11:11] <gordonDrogon> this is why the foundation and a few others produced their own PSUs in the end.
[11:11] <IanTLopp> so... ACTUAL pi charger, or other device providing a real 2.5a means I get a functional pi3
[11:11] <gordonDrogon> ok. are you sure it's not faulty?
[11:11] <IanTLopp> what, the pi3?
[11:11] <gordonDrogon> either.
[11:11] <IanTLopp> considering it runs flawlessly on the official PSU, then yes, I know it's not faulty
[11:11] <IanTLopp> also, my other pi 3 has the same issues.
[11:12] * sphenxes (~sphenxes@81-5-241-122.hdsl.highway.telekom.at) Quit (Ping timeout: 252 seconds)
[11:12] <IanTLopp> more specifically, on any 2.4a or lesser charger, it boots up, gets yellow lightning, and snes is slow... running on either of my two 2.5a chargers (official and non-official) I get no yellow lightning and fast snes.
[11:13] <gordonDrogon> slowdowns are due to thermal throttling - I'm not aware of slowdowns due to low voltage, however it may be a new feature I'm not aware of. the lightning bolt thing is low voltage.
[11:14] <gordonDrogon> you can get a v3 to thermally throttle just with the ARM alone - although you need to run all 4 cores (in my tests anyway).
[11:14] <mfa298> if you've got a really poor psu I think the pi will try to go into 1.2ghz mode, go undervolt and return to the slower clock speed - I found that when I first got the Pi3 and tried to run it with an original (1A) rpi psu
[11:14] <NedScott> I still need more than 1 amp because of the little GPIO LCD screen
[11:15] <NedScott> neat screen, though
[11:15] <nacelle> is there a recommended 3+ amp supply?
[11:15] <nacelle> (or anyone have said recommendation, rather?)
[11:15] * sphenxes (~sphenxes@81-5-241-122.hdsl.highway.telekom.at) has joined #raspberrypi
[11:15] <gordonDrogon> gpio power bypasses the 1.2A limiter for USB.

[11:15] <gordonDrogon> can you power the screen indepedndant of the Pi?
[11:15] <NedScott> yes
[11:15] <IanTLopp> gordonDrogon: I could be mistaken on this level, but I *think* I tested with and without heatsinks... more specifically, I started the unit without heatsinks and had issues, and then after I installed the heatsinks, still had issues... it wasn't until I added the proper amperage that things went faster.... BUT I could be mistaken in that - I only ever tested thoroughly for amperage... I'll test to see if slowdowns occur with
[11:15] <IanTLopp> the yellow icon on a 2.4a device.
[11:16] <NedScott> but having two batteries wouldn't make much sense here
[11:16] * Deruyter (~Deruyter@unaffiliated/deruyter) Quit (Quit: Bye Bye!)
[11:16] <NedScott> it's a GPU accelerated screen using the GPIO
[11:16] <gordonDrogon> no (2 batteries), however - if you took power from the power source (battery, mains, etc.) directly to the screen, it would bypass the on-board 2.5A limiter on the Piv3.
[11:17] <gordonDrogon> so one power source - Y splitter, one leg going to the Pi, one going directly to the display.
[11:17] * Deruyter (~Deruyter@unaffiliated/deruyter) has joined #raspberrypi
[11:18] <NedScott> but if the battery only provides 1 amp of power then it still wouldn't work, right?
[11:18] <gordonDrogon> not if the display needs 1A..
[11:19] <NedScott> display + Pi 3
[11:20] <IanTLopp> I just need to figure out what is limiting the power output of my battery pack.. I'll rip it apart and start studying the pcb
[11:20] <IanTLopp> later.
[11:21] <nacelle> ah so a 3a is basically useless, nice
[11:21] <nacelle> (or underdriven, etc.)
[11:21] <IanTLopp> right now, i'm stoked because my disconnected raspberry pi zero w works with octopi now - just need to connect it to the printer tomorrow and start upgrading the printer with aluminum parts, replacement pieces, etc... then finally recalibrate everything and I'll have a working beast :)
[11:22] <IanTLopp> nacelle: not necessarily - something that is designed to run at 2.5 will be taxed more than something running at 3.0, though to be fair the constant drain is generally much less than 2.5
[11:22] <IanTLopp> though if you have a big screen and the raspi 3 running, the 3.0 would be better
[11:22] <gordonDrogon> just be aware that the Pi has a 2.5A polyfuse on the USB power input.
[11:23] <IanTLopp> gordonDrogon: hmm... so that might be reason enough to have separate power to the screen then.
[11:23] * codestorm (~codestorm@2605:e000:9196:e300:8163:82c2:212:1cbc) has joined #raspberrypi
[11:23] <IanTLopp> especially given my 5" screen coming in, and it's total lack of raspi connectivity (well it has VGA input)
[11:24] <NedScott> have you seen those cheap 5inch HDMI screens on ebay?
[11:24] <gordonDrogon> IanTLopp, that's why I'm suggesting a splitter....
[11:25] <gordonDrogon> the foundation 7" screen can power the Pi via the GPIO connector.
[11:25] <IanTLopp> gordonDrogon: thanks for the info - I hadn't even considered the implications (though I was expecting to use a splitter anyway - or rather a pcb with multiple power outputs for the purposes)
[11:25] <NedScott> http://www.ebay.com/itm/5-inch-Resistive-Touch-Screen-LCD-Display-HDMI-for-Raspberry-Pi-XPT2046-SX-/162465547063
[11:25] <IanTLopp> ahh, that piece of crap
[11:25] <IanTLopp> heh.
[11:25] <NedScott> if you peel off the touch layer then the screen is pretty night
[11:25] <NedScott> err, nice
[11:25] <IanTLopp> sorry, I'm sure it's a fine piece of tech.
[11:25] <NedScott> nah, it's also crap :D
[11:25] <IanTLopp> it's just wide screen
[11:25] <NedScott> I bought two and broke them both
[11:25] <IanTLopp> ahh, didn't know.
[11:25] <IanTLopp> yeesh
[11:25] <gordonDrogon> that looks like the adafruit 5" one - which I have and works fairly well.
[11:25] * thereyougo (partyinpar@unaffiliated/thereyougo) has left #raspberrypi
[11:26] <IanTLopp> well i can't use wide screen, so fmeh.

[11:27] <IanTLopp> NedScott: perhaps... I need to figure out who can make screens to MY specs, rather than just rattle off what they have... I thought alibaba might be the place to go for that, but it's just a weird parts store located mostly in china (I know what it is, I'm just comparing it to what it seems like)

[11:28] <NedScott> I actually bought a kippah when I found out I was going bald
[11:28] <IanTLopp> was there some reason they couldn't go with pihat?
[11:28] <NedScott> not jewish, but it covers the bald spot perfectly
[11:29] <NedScott> technically a Pi hat connects in a specific way
[11:29] <IanTLopp> just read the difference - hats have eeproms, this one does not.
[11:30] <IanTLopp> I'll keep that in mind for other projects, like my ScummPI
[11:30] <NedScott> I've been trying to cram it all into a gameboy DSi XL case, and I'm starting to think I should just make my own with a 3D printer
[11:30] <NedScott> every mm counts
[11:30] <gordonDrogon> To use the 'HAT' name you need the on-board eeprom and follow the foundation specification.
[11:30] <IanTLopp> at any rate, I gotta get to bed..
[11:31] <IanTLopp> gordonDrogon: thanks for the clarification :)
[11:31] <IanTLopp> at any rate... night all.
[11:31] <gordonDrogon> so anything without the eeprom isn't a HAT - at least not officially.
[11:31] <NedScott> https://www.dropbox.com/s/ohzp159v08a5c73/we_must_go_smaller.jpg?dl=0
[11:31] <NedScott> it's like a horror film
[11:31] <NedScott> I just hacked away at it
[11:31] <IanTLopp> NedScott: well I'm trying to find a 1.8" screen running at 320x240... THAT small enough?
[11:31] <NedScott> hehe
[11:32] <IanTLopp> raspi 3 with everything desoldered?
[11:32] <IanTLopp> or... cut off?? ouch
[11:32] <NedScott> ripped up pads on the PCB when I tore off the camera connector
[11:32] <IanTLopp> I'm planning to desolder everything
[11:32] <NedScott> I started doing that and then got really bored
[11:32] <IanTLopp> yeah, I'll be desoldering...
[11:32] <IanTLopp> *rolls eyes*
[11:32] <IanTLopp> do NOT let Ben Heck hear you say that.
[11:32] <NedScott> it works perfectly, still

[11:33] <NedScott> at first I was going to keep the two lower USB ports. I don't have a picture of it anymore, but shopping off the top half of the USB ports works out really well
[11:33] <gordonDrogon> 1.8" at that resolutions? tricky ..
[11:33] <IanTLopp> I'm putting a raspi zero inside http://photos1.blogger.com/blogger/3349/1529/1600/vee-em-you.jpg and turning it into a 16-bit emulation console.
[11:33] <NedScott> nice
[11:34] <IanTLopp> gordonDrogon: tricky to buy... i can find plenty of tech with that screen, but nobody sells JUST the screen... ergh.
[11:34] <IanTLopp> it's mostly in older "mp4 players"
[11:34] <gordonDrogon> ok
[11:34] <IanTLopp> even touch screen no less... but I can't find the screen with or without a controller board.
[11:34] <NedScott> I had a tiny CRT that size once. Well, about that size
[11:34] <gordonDrogon> plenty of 2.8" displays designed to fit over the old Pi size.
[11:34] <NedScott> came out of the viewfinder of an old camcorder
[11:35] <NedScott> I wish I still had it. It was awesome and worked with a composite video signal and ran off of a few AA batteries
[11:35] <IanTLopp> the "best" 1.8" screen I can find is the adafruit one, but there IS a 1.8" screen with a slightly higher resolution than the adafruit unit... I'll have to look again, but I'm not interested until I get the 320x240
[11:35] * batch (~batch@unaffiliated/batch) has joined #raspberrypi
[11:37] <NedScott> the other fun thing I want to do with Pis and small screens, is make an offline TV
[11:38] <gordonDrogon> I already have one of those - it's called a mobile phone ;-)
[11:38] <NedScott> 3D print a tiny "TV" enclosure, like an old 50's style CRT, then load in Kodi and the pseudo TV add-on and a bunch of tv show video files
[11:38] <HrdwrBoB> heh
[11:39] <HrdwrBoB> for additional realism
[11:39] <NedScott> the Pseudo TV add-on looks at all of the videos and presents them like TV channels, complete with an EPG grid. Like you can tune to a channel and it will be in the middle of the episode, according to the time
[11:39] <HrdwrBoB> add a lense in front of it to give it curvature
[11:39] <NedScott> haha, yes
[11:39] <NedScott> even add in some GPIO buttons for chan up/down
[11:40] * ninjak (~ninjak@82.84.82.8) has joined #raspberrypi
[11:40] <IanTLopp> I want to gut one of these (the tube itself), install a reverse side projector screen, then a projector on the inside. Run a computer through it, and somehow put some kind of filter on the video output to have it fit the shape of that screen exactly.
[11:41] <IanTLopp> NedScott: NOO... you gotta have dials for UHF and VHF! 2-13-U, then 14-69!
[11:41] <NedScott> ah, even better
[11:41] * wiiguy (~fake@unaffiliated/wiiguy) has joined #raspberrypi
[11:41] <NedScott> that would be tricky at that size, but probably possible
[11:41] <HrdwrBoB> or
[11:41] <HrdwrBoB> just find an old TV
[11:41] <HrdwrBoB> hijack the buttons
[11:42] <HrdwrBoB> although that's becoming much harder these days
[11:42] <HrdwrBoB> I was in a hungry jacks yesterday (burger king) and they had a CRT TV in the party room

[15:29] <Milca> I have a rpi with the 7 touchscreen
[15:29] <Milca> worksfine
[15:29] <Milca> but I'd like it to display on hdmi output when hdmi is plugged in
[15:29] <Milca> at lease before boot
[15:30] <Milca> (i mean if I plug it in before booting)
[15:30] <Milca> do you think that's manageable ?

[15:52] <hgsfn> hi are there any information about how the broadcom wifi chip's power up sequence is controlled in in raspberry pi 3 model B, would like to know if they are controlled purely by hardware or controlled by gpio pins? Especillay would like to know how WIFI_REG_ON is handled
[15:52] <Chillum> gpio pins are hardware

[15:57] <hgsfn> ok thanks, so all timiing requirements of 3V followed by WIFI_REG_ON is handled in hardware?
[15:58] <Milca> leftyfb: in fact as you said you can't have both
[15:58] <Milca> the proble is how to have only hdmi => just add ignore_lcd in config.txt
[15:59] <Milca> apparently there is a solution to do the modification of config.txt if you use PINN
[15:59] <hgsfn> iam trying to interface BCM4339 thru SD1 and I am seeing following dmesg "error -110 whilst initialising SDIO card", as I am new to drivers so need guidence on debuggin the issue
[15:59] <Milca> and ultimate solution leftyfb => I just unplugged the hdmi ....

[18:31] <Budd> How can I measure house current with a Raspberry Pi? I'm failing to find either Hall effect sensors or clamp ammeters that look easy to interface.
[18:32] <Habbie> Budd, find a cheap second hand current cost and just read out the serial
[18:32] <Habbie> Budd, bonus, you get a display to put somewhere
[18:34] <Budd> I hadn't heard of Current Cost before - looking it up.
[18:36] <Habbie> a bit roundabout perhaps, but i know it works

[18:37] <Budd> They're not too geek-oriented, and it's hard to see how their setup works - does the sensor have a serial out, or does it have to boucne (wireless?) to the control box first?
[18:37] <Habbie> the sensor goes wireless to the display box
[18:37] <Habbie> the serial port is on the display box

[18:39] <Habbie> Budd, there is code out there
[18:39] <Budd> Awfully nice of them to ofer a documented data out - not too many companies encourage hacking like that.
[18:39] <Habbie> indeed
[18:40] <Habbie> as the blog post notes, you can buy a suitable usb receiver for 5 bucks
[18:40] <SpeedEvil> currentcost actually (at one point, unsure of now) had bare PCBs for sale on ebay to do interesting stuff.
[18:40] <Habbie> and then your pi does not need to be close to the display box
[18:41] <Habbie> SpeedEvil, oh, that's cute
[18:41] <Habbie> so definitely geek oriented
[18:41] <SpeedEvil> Seemingly not now
[18:41] <Budd> I found an affortable switchable power strip from sparkfun recently, but other 110V-safe interfaces are a little hard to come by.
[18:42] <SpeedEvil> sonoff and friends
[18:42] <Budd> (but switchable power strip + 1-wire thermometer = climate-controlled seedlings :)
[18:42] <SpeedEvil> wifi, esp8266 in a box
[18:42] <Habbie> yes sonoff is super cute
[18:42] <Psi-Jack> Heh
[18:43] <Psi-Jack> Sonoff is neat, but as-is isn't really "safe", unless you nicely hide the box somewhere humans can't simply touch it. And the lack of ground wire support is just silly.
[18:43] <Budd> thanks for all the leads - this shoudl keep me happy for a while.

[18:47] <Chillum> and you can also re-purpose the LED or button gpio

[18:48] <Chillum> I set it up with a divider

[20:25] <strixUK> nacelle, Habbie- thanks for confirming that. that's useful to know because a question mark was raised over bandwidth considerations in conjunction with SDR dongles
[20:25] <strixUK> if network is also USB, that would mean that 40 Mb/s @ 2.4 MS/s is going both ways on the one USB 2 root port.
[20:25] <binaryplease> HI, I just saw this: https://getchip.com/pages/pocketchip and thought I could build my own with a raspi. Are there any good thumb keyboards for the raspi? Possible with enclosure?
[20:26] <Habbie> strixUK, yes - can't you decode on the pi?
[20:27] * KindOne (kindone@freenode/father-christmas/kindone) has joined #raspberrypi
[20:27] <strixUK> Habbie: good question, i've only just ordered the SDR and I don't have a pi yet. i assumed that it'd be simpler to do DSP on a desktop computer assuming the IQ stream could be fed via wireless, and that it'd be easier to bridge the IQ stream via the pi than do processing onboard
[20:27] <nacelle> strixUK: wifi isn, ethernet is, so going over wifi wouldnt have that problem
[20:27] <strixUK> but v3 is quad core, so... maybe it has enough power to do everything locally?
[20:28] <Habbie> strixUK, what are you decoding?
[20:28] <strixUK> well, if i get my way, i'd like to have two SDRs, one doing AM and the other doing ADS-B
[20:28] * mal_will (uid195162@gateway/web/irccloud.com/x-fmbatviutlmevtjc) has joined #raspberrypi
[20:29] <Habbie> ADS-B should be no problem for a pi
[20:29] <strixUK> you'd think that AM wouldn't require much in the way of processing. no idea what ADS-B looks like at that level.
[20:29] <strixUK> i wouldn't have thought so. it's just data, and not much of it
[20:29] <Habbie> sites like flightradar are mostly fed from Pis is my impression
[20:29] <Habbie> and have been so for years
[20:29] <Habbie> they even provide a pi image
[20:30] <strixUK> but i have zero idea of what a pi's capabilities are, so i'm making no assumptions. i only recall that ssh into a pi was.. a bit painful. but that would have been an earlier model pi, i think.
[20:30] <Habbie> it's gotten a lot better, yes
[20:30] <Habbie> and there is no crypto in ADS-B
[20:30] <strixUK> i should hope not. if there were, looking at it would be naughty.
[20:31] <Habbie> indeed
[20:31] <Habbie> but there isn't, i'm pretty sure
[20:31] <strixUK> no, i'm pretty sure (nearly certain) that ADS-B is not encrypted.
[20:31] <Habbie> uhuh
[20:31] <Habbie> so what are you doing on AM?
[20:31] <Habbie> listening to radio?
[20:31] <strixUK> ADS-B might give you a hint ;)
[20:31] <strixUK> yes
[20:31] * h0schi (~hoschi-it@2a02:908:1b0:c500:a139:c9b6:6c6f:bf27) has joined #raspberrypi
[20:31] <Habbie> should also be fine
[20:32] <Habbie> and given that i think dump1900 is not threaded, you'll have three cores left
[20:33] <strixUK> i assume AM decoding would also be single threaded. why would you need more? the IQ stream is virtually PCM as it is (just missing rectification)
[20:33] <BurtyB> my piaware pi3 is 90% idle on the cpu side (load avg 0.23) and most of that is dump1090
[20:33] <strixUK> and maybe a bit of scaling
[20:33] <Habbie> BurtyB, good to know
[20:34] <strixUK> BurtyB: excellent news
[20:34] <strixUK> so maybe i can do everything i want directly on the pi and just stream the audio

[21:30] <ball> Understood.
[21:31] <strixUK> but, it looks promising: a metal case is a good start, they've taken some trouble over heat dissipation, it's got a nice TXCO in it and it has a higher performance tuner than most SDRs of that class (R820T2 vs R820T)

[21:54] <ball> "non-feature phones" are smartphones ;-)
[21:54] <ball> "feature phones" are non-smart phones.
[21:54] <ball> (typically)
[21:54] <Habbie> feature phone is such a great marketing term
[21:55] <GekkePrutser> I use a lot of 2G modems in IoT roles and they still work on every network I tried

[21:57] <GekkePrutser> Not here in Ireland but they never were
[21:57] <Habbie> GekkePrutser, from your name i assumed different networks ;)
[21:58] <Psi-Jack> ball: I /know/ it would.
[21:58] <GekkePrutser> Oh yes I live in Ireland. I visit NL sometimes but I'm not sure what they sell there
[21:58] <Psi-Jack> ball: The difference is MetroPCS policies vs T-Mobile policies.
[21:58] <Habbie> GekkePrutser, NL is 3G country - tele2.nl is 4G only and for a while they only sold non-simonly contracts to make sure people wouldn't use 3G phones too much on their network
[21:58] <ball> Thanks Psi-Jack

[22:00] <GekkePrutser> But you're right I have no idea what they do with 2G
[22:00] <Habbie> yes, those are the existing 2/3/4G networks, plus tele2 with just 4G
[22:00] <Habbie> and all of them want to kill 2G
[22:00] <Habbie> because the spectrum is so much more valuable at higher bit rates
[22:00] <Psi-Jack> Heh, my wife is in Japan & Okinawa now, enjoying the benefits of having LTE overseas with unlimited data. :)

[22:01] <GekkePrutser> But 3 and 4g use more bandwidth. The modulation is a bit more efficient but not that much
[22:01] <Habbie> not more bandwidth per bit, right
[22:02] <GekkePrutser> But I suppose they want the better coverage of the lower bands
[22:02] <ball> I pay UKP 28/month for "all you can eat", with up to 1GB of LTE.

[22:31] <mrkramps> that could be annoying ;)

[23:05] <shauno> usually when you see 'broken pipe' in rsync, it's the last item in a longer error, and the least interesting part. Usually "what went wrong" is at the start of the error, and 'broken pipe' is merely a symptom (it just means the process ended before the job was done)

[23:11] <Psi-Jack> LIke I said, it's easily either a network communication issue, or disk I/O issue.
[23:11] <sware> okay well there's no problem with disk i/o and it does work once every 10 times or so

[23:37] <Psi-Jack> That means that an open file was locked open, retaining the file desciptor.
[23:37] <ball> If you have any files on your raid0 that aren't elsewhere, I would back them up onto something more sane.
[23:38] <Psi-Jack> Hmm, oh, different issue. :)
[23:38] <alexandre9099> ball: well, i use that raid 0 storage to backup my computer data, so unless my main computer dies it is also on my main computer
[23:38] <Psi-Jack> alexandre9099: Hmm, RAID 0 is definitely not backup...
