[0:31] <innkeeper> i've noticed while reading about how to overclock a raspberry pi 2 theres been great variations on overclock sucsess.
[0:32] <innkeeper> does tcorelate at all on who actualy made them?
[0:32] <ozzzy> why bother
[0:33] <innkeeper> i use it mostly for playing flack files using volumio
[0:33] <innkeeper> so at a standard clock rate, i will sometimes get loss
[0:33] <innkeeper> so, thats why id bother.
[0:34] <ozzzy> you should be able to choose any of the settings in raspi-config without problem
[0:34] <Ryccardo> define "success" -- it's changing the maximum frequency of the ondemand governor, it's not at that speed 24/7 by default
[0:34] * TyrfingMjolnir (~Tyrfing@90.149.171.52) has joined #raspberrypi
[0:36] <innkeeper> i am talking about forceturbo - overvolting etc
[0:36] <innkeeper> and sucsess really dos mean how far you can ush it
[0:36] <innkeeper> not that you can overclock it some
[0:40] <innkeeper> so in exaple increasign sdram fequency will ahve a limit dependant on the memory chips
[0:40] <ozzzy> I run mine at 1GHz but it sits at 600MHz most of the time
[0:40] <innkeeper> so unless all makers are using the exact same chip, one would ahve toa sume thres a diffrnce amoung the diffrent companies makign them

[0:43] <Ryccardo> regardless of actual assembler, they probably buy 1000 chips from the best supplier at any time they need more
[0:43] <Ryccardo> or so would I do

[1:00] <Ownix> Tenkawa: I got it working thanks for your help
[1:03] * Tachyon` is now known as Tach[Zzz]
[1:04] <maxbots|mtw> I just installed ubuntu-mate on my rpi and now my display is intermittently flickering
[1:04] <maxbots|mtw> It was working fine before with raspbian
[1:04] <maxbots|mtw> I unplugged the HDMI cable and plugged it back in and it helped, but still flickers a bit
[1:05] <maxbots|mtw> any ideas about what would cause that?

[1:16] * edux (~edux@181.167.161.210) Quit (Ping timeout: 244 seconds)
[1:18] <maxbots|mtw> Changing back to Raspbian fixes the problem, but I prefer Ubuntu if possible
[1:19] * eXtremo (~eXtremo@unaffiliated/extremo) Quit (Ping timeout: 265 seconds)
[1:20] <Froolap> which version of pi?
[1:20] <maxbots|mtw> 2
[1:21] <maxbots|mtw> model b
[1:21] * eXtremo (~eXtremo@unaffiliated/extremo) has joined #raspberrypi
[1:22] <Froolap> could be issues with fbturbo.
[1:22] <maxbots|mtw> The screen looks good and everything, but intermittently just goes blank for a second or so
[1:23] <Froolap> screen saver and or power management....
[1:23] <Froolap> is that your desktop or is it when you are streaming video?
[1:23] * ad3847 (~ad38475@unaffiliated/ad38475) Quit (Ping timeout: 258 seconds)
[1:24] * AMERICAN_PSYCHO (~AMERICAN_@c-75-65-104-122.hsd1.la.comcast.net) Quit (Ping timeout: 255 seconds)
[1:24] <maxbots|mtw> Neither, basically the desktop
[1:24] * j12t (~j12t@c-107-3-142-14.hsd1.ca.comcast.net) Quit (Remote host closed the connection)
[1:24] <maxbots|mtw> it is going to be aserver eventually
[1:25] * j12t (~j12t@c-107-3-142-14.hsd1.ca.comcast.net) has joined #raspberrypi
[1:25] <maxbots|mtw> screen saver and power management should both be disabled
[1:26] <maxbots|mtw> unplugging the HDMI cable seems to fix it, but it comes back after a bit, and it seems to get progressively worse to the point it becomes unusable unless I unplug the HDMI again
[1:26] <maxbots|mtw> then it goes back to normal for a while
[1:26] * Syliss (~Syliss@dpncorp1.digitalpath.net) Quit (Quit: Syliss)
[1:27] * pmumble (~pmumble@unaffiliated/pmumble) Quit (Ping timeout: 265 seconds)
[1:27] <Froolap> maybe it's a problem with the tv. the pi only looks at the monitor resolution at boot.
[1:28] <maxbots|mtw> It works fine when I use raspbian, so that seems to eliminate hardware
[1:28] <maxbots|mtw> And normally this monitor is plugged into my Windows box
[1:28] * pmumble (~pmumble@unaffiliated/pmumble) has joined #raspberrypi
[1:28] <maxbots|mtw> So it definitely is not the monitor
[1:29] <Froolap> maybe the process of disconnecting and reconnecting the hdmi keeps your fingers off the keyboard so it's not busy for a bit.
[1:29] <maxbots|mtw> fbturbo is probably the best guess, reading a bit on it now
[1:29] <maxbots|mtw> Doesn't matter whether I am doing anything on it or not
[1:30] * j12t (~j12t@c-107-3-142-14.hsd1.ca.comcast.net) Quit (Ping timeout: 272 seconds)

[1:35] <justicefries> any retropie folks here? I'm trying to find the post that describes how to turn the select button ont he xbox 360 controller into a back button.
[1:38] <maxbots|mtw> Froolap: Think I found it
[1:38] <maxbots|mtw> http://elinux.org/RPiconfig
[1:41] <maxbots|mtw> err https://www.raspberrypi.org/forums/viewtopic.php?f=28&t=7407
[1:41] <maxbots|mtw> the 4th one there
[1:42] <maxbots|mtw> so far so good, after rebooting it seems tsable

[4:33] <Triffid_Hunter> Ownix: sure, use sshfs to network mount the relevant section of filesystem
[4:33] <Ownix> Triffid_Hunter: what about on a windows machine?
[4:33] <Triffid_Hunter> Ownix: you probably want hpn sshfs with the null cipher to avoid doing encryption on the rpi and causing the same issue
[4:34] <Ownix> welp that sounds over my head lol
[4:34] <Triffid_Hunter> Ownix: windows? heh, install cifs on the rpi, set up a shared folder, do the same thing there
[4:34] <Triffid_Hunter> sorry, install samba. cifs is the protocol
[4:34] <Ownix> But would my computer really be doing the extraction? All youre saying is just host the file as a share right?
[4:35] <JK-47> it would be slow. you would be reading it in and writing it out as you extract
[4:35] * edux (~edux@181.167.161.210) has joined #raspberrypi
[4:36] <Ownix> the real question is whats slower
[4:36] <Ownix> letting the Pi extract a 7.5GB RAR file or doing it over the network
[4:36] <Triffid_Hunter> Ownix: everything on RPis is slow except playing HD video via the HDMI port
[4:37] <Ownix> even that has to use the GPU right?
[4:37] <Triffid_Hunter> it uses the vpu
[4:37] <Triffid_Hunter> which is a little like the GPU but it's specifically designed for video decoding rather than 3d graphics

[4:41] <Ownix> ah
[4:41] <Ownix> streamlined to be an HTPC
[4:41] <Ownix> Or a little dev board
[4:41] <Ownix> but if you make it also download and extract things its not the best for that
[4:42] <Ownix> Almost need a home server
[4:42] <Ownix> and then ditch the pi for a Chromecast
[4:42] <Ownix> because at that point, whats the point?

[4:56] <Ownix> yeah I might sell mine in a month or so and build a little i5
[4:58] <Froolap> you are going to sell your pi?
[4:58] <Ownix> mayhaps
[4:58] <Ownix> in the future.
[4:58] <Ownix> Its not powerful enough for me. And I didnt consider all the things id need it to do fast when I bought it
[4:59] <JK-47> or they are so cheap, give it to some kid to start his career in technology :P
[4:59] <Ownix> well I bought mine as a kit for like $80
[5:00] <Ownix> It could be a good jumping off point for a barebones pc on newegg
[5:00] <Ownix> http://www.newegg.com/Mini-PC-Barebone/SubCategory/ID-309
[5:01] <JK-47> i keep buying more and more. never ending uses.

[5:03] <JK-47> if this than that.
[5:04] <dLux> hay there, anyone use eggdrop on ubuntu-mate via apt-get (vs. compile from src)..?
[5:04] <JK-47> https://ifttt.com/smartthings
[5:04] <dLux> i’m wondering about init.d
[5:04] <JK-47> basically ifttt is a collection of rules that fire, and then kick off other things
[5:04] <dLux> it’ll just start it, ya? not monitor it and keep it running?
[5:04] <JK-47> "if motion detected, take picture, and then upload to dropbox, and send email"
[5:04] <dLux> still need the crontab that does that?
[5:04] <JK-47> through web services
[5:04] <JK-47> or "if door opens, turn on my web enabled lights"
[5:05] <Ownix> ah
[5:05] <Ownix> thats neat

[6:45] <tf2manu994> it is
[6:45] <pmumble> pi is mighty
[6:45] <tf2manu994> im waiting for my fans to come

[6:59] <tf2manu994> anyone know if using a 5v fan would damage the gpio?
[6:59] <steve_rox> depends how much ma it pulls
[6:59] <tf2manu994> 5v
[6:59] <steve_rox> current
[7:00] <steve_rox> ive seen clowns put fans on the gpio and it instantly reboots the rpi from the power drain
[7:00] <Froolap> get a hampster and then keep your pi under that hampster's wheel and you don't need to power the fan.
[7:00] <temmi_hoo> steve_rox: what? depending on the package, smd's are easier
[7:01] <temmi_hoo> unless you go to 0204 and the like
[7:01] <steve_rox> well try solder the rpi main cpu
[7:01] <temmi_hoo> sorry, no :)

[7:01] <steve_rox> i built a DSO138 in these last few days
[7:02] <steve_rox> and that was kinda tricky
[7:02] <temmi_hoo> steve_rox: at the helsinki hacklab we're soon having a soldering oven so then 0204 bga cfn and the like become possible
[7:02] <temmi_hoo> although positioning 0204 will continue staying on the borderline of being doable and far from being enjoyable

[7:03] <steve_rox> ah , i was soldering tiny smt resitors on with soldering iron
[7:03] <tf2manu994> the fan pulls 5v at .2a
[7:03] <steve_rox> the kind where if you sneeze they are gone
[7:04] <tf2manu994> anyone?
[7:04] <steve_rox> as long as you dont pull too much current from the gpio your be okay
[7:05] <steve_rox> a smoothing cap may help too maybe
[7:05] * ryush (~ryush@66-215-168-143.dhcp.ccmn.ca.charter.com) has joined #raspberrypi
[7:06] <temmi_hoo> steve_rox: 0204 can be hand soldered but placing them is annoying beyond words
[7:06] <temmi_hoo> hold them down with tweezer, touch the gun and touch again and you're good
[7:06] <steve_rox> i had to improvise some tools to hold them in place
[7:07] <steve_rox> a wooden ice cream stick carved to a point
[7:07] <tf2manu994> is 5v and 0.2a safe?
[7:07] <steve_rox> then you haave to deal with the component sticking to the end of the iron
[7:07] <temmi_hoo> tf2manu994: yes, the raspi can give you that through its 5v supply
[7:07] <steve_rox> then its a race aggenst time to get it off before the iron totally destroys it
[7:07] <temmi_hoo> if you want fan control you want to hook an n channel mosfet to drive it from gpio
[7:08] <tf2manu994> temmi: safely?
[7:08] <steve_rox> i was thinking about heatsinking the rpi/fan but then i just noticed its prob go faster stripes and not too significant
[7:09] <steve_rox> if you were liveing in a hot desert enviroment mayyybe it would be a good idea
[7:09] <temmi_hoo> tf2manu994: yes it can
[7:09] <tf2manu994> temmi: thanks :D
[7:10] <temmi_hoo> if you power the raspi through usb, you might get trouble from too long too thin usb cable

[7:12] <temmi_hoo> tf2manu994: i'm suggesting you just let the fan rip full on without bothering any kind of control scheme to it
[7:13] <tf2manu994> yup
[7:13] <steve_rox> mine dont have any control on it
[7:13] <temmi_hoo> and then do consider power over ethernet

[7:13] <steve_rox> thats a expensive addon
[7:13] <temmi_hoo> it is, sorry about that
[7:13] <tf2manu994> eh, i dont have a poe router
[7:14] <steve_rox> since cooling the rpi is a sorta errelivent not too important you dont wanna spend insane ammounts

[8:48] <MACscr> probably not the best place to ask, but anyone seen any pi cases with built in power supplies that will basically just plug into an outlet? Just seems like an obvious thing that I am surprised i havent found yet on google
[8:48] <JK-47> print one
[8:48] <JK-47> but really, why keep the heat of the wallwart transformer or joule theif next to the board, and not on the wall?
[8:49] <[Saint]> its not really any issue.
[8:49] <[Saint]> pi won't care.
[8:49] <MACscr> exactly, plus we are talking about an all in one solution
[8:49] <MACscr> no crappy cords
[8:50] <MACscr> and a great way to put a pi in each room for home automation stuff
[8:50] <MACscr> take temps, humidity levels, do voice commands, etc
[8:50] <JK-47> you still need a cord somewhere

[8:51] <MACscr> thanks [Saint]
[8:52] <MACscr> nice looking, but doesnt seem to really do anything besides look nice =P
[8:52] <[Saint]> it puts all the cables in one place, at least, for a nicer aesthetic.

[8:54] <JK-47> should be easy to print

[9:43] <MACscr> hmm, now that it think of it, a temperature sensor directly on a pi isnt going to work that great as the power adapter and the board itself is going put off heat and thus leading to poor readings from the temp sensor i would tink
[9:43] <MACscr> think
[9:45] <temmi_hoo> that indeed
[9:46] <temmi_hoo> so use a i2c or onewire or onewirish sensor mounted in a reasonable place
[9:46] <temmi_hoo> it's not like you have the 230vac socket conveniently located just where you'd want to measure anyway
[9:47] <MACscr> but i do, though only 110v here =P
[9:47] <temmi_hoo> you poor you have to deal with half the voltage!
[9:48] <temmi_hoo> more copper or more losses for the same power

[12:28] <Encrypt> "Pin 3 is now given a voltage of between 0V and 5V via the middle pin of a 10Kohm trimming pot so that the display contrast can be adjusted."
[12:28] <info452-1> this is get me crazy, i already tested two lcd
[12:29] <Encrypt> Connecting it to GND seems to me really weird
[12:29] <Encrypt> If you have a potentiometer, you should try that
[12:29] <info452-1> i will upload the schematic of the lcd
[12:29] <Ryccardo> Encrypt: isn't 0 between 0 and 5? :)
[12:29] <Encrypt> It is :P
[12:30] <Encrypt> Ryccardo, But the contrast will be so weak
[12:30] <Encrypt> It doesn't sound to me like a good idea
[12:30] * injigo (~injigo@unaffiliated/injigo) has joined #raspberrypi
[12:31] * ByteCrunch (~bitecrunc@bytecrunch.de) has joined #raspberrypi
[12:31] <Ryccardo> that's the weird thing, for some reason 0 was the best when using an arduino and an external power brick for the display, but not when only connected to a pi
[12:32] <Encrypt> I imagine it depends on the brand of the LCD display
[12:34] <info452-1> this is the lcd owners manual https://www.dropbox.com/s/rxrw631zt2qmm5t/PG12232WRM-CAN-EY1.pdf?dl=0
[12:35] <Encrypt> info452-1, You should enable the "public" folder
[12:35] <info452-1> as you can see on page 9
[12:35] <Encrypt> That's handy
[12:35] * Tach[Zzz] is now known as Tachyon`
[12:36] <Triffid_Hunter> info452-1: most character LCDs use HD44780 or clone. sometimes they work with contrast grounded, sometimes they just look blank.
[12:36] <Triffid_Hunter> info452-1: one good feature of the HD44780 is that when it starts up, the top row has black blocks so you can get the contrast right with only power applied
[12:37] <Triffid_Hunter> ps: the HD44780 itself wasn't compatible with 3.3v logic, but most of the modern clones are
[12:37] <Ryccardo> yup, this thing you linked doesn't look like the standard Hitachi
[12:37] * platzhirsch (~konrad@cpc71651-walt17-2-0-cust75.13-2.cable.virginm.net) Quit (Quit: Leaving.)
[12:37] <info452-1> mmm
[12:37] <info452-1> the lcd gets the power from another source not the pi
[12:38] <Triffid_Hunter> info452-1: forgot to connect grounds perhaps?
[12:38] <info452-1> i put the contrast to ground with the vss and the pin 16 also to gnd
[12:38] <info452-1> i don-t know, the lcd does not display the blocks when it starts
[12:39] <Ryccardo> does it have 16 or 18 pins?
[12:39] <info452-1> 18
[12:39] <info452-1> pin 15 and 16 is for the lcd backligh
[12:39] <Triffid_Hunter> info452-1: best slap a potentiometer on that contrast pin and have a fiddle with it
[12:40] <Ryccardo> yup, but the common Hitachis have 16 pins and from the manual this appears to have a different protocol
[12:40] * Keanu73 (~Keanu73@unaffiliated/keanu73) Quit (Quit: Leaving)
[12:40] <info452-1> even without the rs, rw and enable pins, should display the squares on the start_
[12:40] <info452-1> ?
[12:41] <Ryccardo> yes, just with power on 1 and 2 (plus backlight if you want, but it's independent of the logic)
[12:41] <Triffid_Hunter> info452-1: yes precisely
[12:41] * j12t (~j12t@c-107-3-142-14.hsd1.ca.comcast.net) Quit (Ping timeout: 255 seconds)
[12:41] <info452-1> mmm
[12:42] <info452-1> somethings wrong then, because with the pin 1, 2 and pin 16, 17 and the contrast to gnd no square are displaying
[12:42] <Triffid_Hunter> info452-1: getting a 404 on your manual pdf
[12:42] <info452-1> i moved it

[12:45] <info452-1> :p
[12:45] <andoma> is there a way to programatically get the rpi model?
[12:45] <Triffid_Hunter> although the protocol does look like HD44780 standard
[12:46] <info452-1> Triffid_Hunter, mmm
[12:46] <Triffid_Hunter> why would they specify pixel resolution for a character lcd? doesn't make sense
[12:46] <Ryccardo> andoma: I heard you can compare the revision numbers in /proc/cpuinfo to a table
[12:46] * hamrove (~hamrove__@96-8-209-215.block0.gvtc.com) has joined #raspberrypi
[12:46] <andoma> Ryccardo: make sense.. i wonder if there is such a table somewhere though?
[12:46] <Triffid_Hunter> info452-1: see page 9. it shows a pot for the contrast adjust
[12:47] <Triffid_Hunter> in fact they even have a negative voltage for it.. that's a bit cheeky
[12:47] <info452-1> mmm

[12:48] * AbouEmre (~Thunderbi@196.216.8.137) has joined #raspberrypi
[12:49] <info452-1> so they get the volts from the vdd and then with a 10k resistor low the volts to the contrast? maybe that why does not show the squares?

[12:50] <AlephTwo> anybody here installed Gogs on a PI2?
[12:51] <Ryccardo> andoma: higher significant bits are used to indicate major overclock
[12:51] <andoma> ah ok
[12:51] <Triffid_Hunter> info452-1: yeah the contrast voltage needs to be at a specific voltage +/- about 0.8v for the screen to be visible. I don't have any screens that actually require a negative voltage, if yours needs one it's fairly easy to make with a charge pump
[12:51] <info452-1> the display looks great for any project, i have almost 150 of them that why i need to make it work :) check out the size https://www.dropbox.com/s/fhq5i2nl5r8a8xj/20150529_172433.jpg?dl=0
[12:52] <Triffid_Hunter> info452-1: looks like the ordinary size for 20x4

[12:58] <Ryccardo> not likely, the example clearly shows it accepts up to 5, but it may not be an acceptable setting
[12:58] <info452-1> i just test it, no squares on startup

[16:36] <AlephTwo> It was failing to run locally, but was getting further (some config issue with http port)
[16:37] <AlephTwo> Now I get permission denied :(

[16:38] <strobelight> noexec is the issue

[16:55] <Ownix> Hey guys I have a toy that runs off of 2 AA batteries, is it possible to supply this same voltage and amperage to it through the GIPO?

[16:55] <AlephTwo> Ownix: I wouldn't. You could power a transistor from the GPIO and use it to turn on & off a separate power supply
[16:56] <maxbots|mtw> The voltage probably, the amperage almost certainly not
[16:56] <Ownix> Hmm okay well look at this
[16:56] <SirLagz> woo got my 3 DS18B20s reading out to SNMP
[16:56] <Ownix> https://i.imgur.com/m6buPYx.jpg
[16:57] <Ownix> You see that 104 thing? There is a momentary switch attached to it
[16:57] <Ownix> I'm guessing it shorts the power supply to the device so it "restarts" and makes a noise
[16:57] <Ownix> https://i.imgur.com/MpWeINI.jpg
[16:58] <Ownix> https://i.imgur.com/tXCpNir.jpg
[16:58] <AlephTwo> yay!
[16:58] <Ownix> So does that mean I could somehow use the pi to replace the switch?
[16:58] <maxbots|mtw> Ownix: The 104 thing is a capacitor
[16:58] <Ownix> Ahhh
[16:58] <maxbots|mtw> You can definitely use the Pi
[16:58] <Ownix> So how does it make the device make a noise?
[16:59] <maxbots|mtw> you just can't use it without any other components

[17:00] <maxbots|mtw> I know a bit, but far from an expert

[17:09] * SopaXT (~SopaXorzT@unaffiliated/sopaxorztaker) Quit (Ping timeout: 250 seconds)
[17:09] <Ownix> Because it was hooked to a cat clock

[17:09] <maxbots|mtw> ah
[17:09] <maxbots|mtw> has it worked at all since you removed it?
[17:09] <Ownix> I disconnected it though and got it working without the clock through trial and error
[17:09] <Ownix> Yes
[17:09] <maxbots|mtw> ok

[17:11] <maxbots|mtw> but as for activating it from the Pi, you need a transistor to let you drive more current than the Pi pin can handle
[17:11] <maxbots|mtw> should be plenty of sample circuits available, see the Arduino site for samples if nothing else
[17:12] <Ownix> maxbots|mtw: well did you see the pic with my desperate battery pack?
[17:12] <Ownix> Technically now all I need the pie to do is to complete the same circuit that the button does
[17:12] <maxbots|mtw> this one? https://i.imgur.com/9Q0RIT8.jpg
[17:12] <Ownix> Yeah
[17:12] <maxbots|mtw> Yes, I understand
[17:12] <Ownix> I have that power
[17:12] <maxbots|mtw> the voltage that puts out is similar to the pi, 3v instead of 3.3v
[17:13] <maxbots|mtw> the problem is the battery can put out a lot of current
[17:13] <maxbots|mtw> if you tried to switch that directly on the Pi, you would blow up the pin
[17:13] <maxbots|mtw> it can only handle a tiny amount of cuurrent
[17:13] <ShorTie> like 15-16ma

[17:15] <Ownix> Is there a way to just send the cat noise to the speaker?
[17:16] <maxbots|mtw> Yes, you could just generate the cat noise on the pi
[17:16] <maxbots|mtw> yoou would need to figure out how, or just record a real cat and play it back

[19:49] <SpeedEvil> you would conect the input of that with a 1K resistor to a GPIO, and to the pis ground.
[19:49] <SpeedEvil> And the other side in series with a fan.

[19:56] <SirLagz> Actually I could probably use some cat5 to extend the GPIO into the roof cavity
[19:56] <AlephTwo> microcontroller (arduino/etc) attached to fan power system via relay. IR receiver on the arduino, IR transmitter on the pi
[19:56] * SirLagz clicks
[19:56] <SirLagz> AlephTwo: yeah I was considering that idea too
[19:56] <AlephTwo> Or a web-enabled power socket & plug the fan into that
[19:57] <AlephTwo> some fancy pi scripting and you have wifi temperature controller
[19:57] <SirLagz> AlephTwo: that's also a possibility...though I'm pretty sure it's illegal for me to replace the power socket. Not that it's going to stop me from doing that heh
[19:57] <AlephTwo> Ceiling fan?

[19:57] <AlephTwo> You could find where it hooks into your mains supply and get an electrician to put a socket there

[19:58] * frib (~none@109.236.21.53) has joined #raspberrypi

[19:58] <SirLagz> AlephTwo: so the room isn't built yet
[19:59] <SirLagz> pksato: that energie pi mote is pretty cool
[20:00] <AlephTwo> Personally, I'd go with an arduino yun and mains relay at the fan outlet. Control it via the wifi/ethernet.

[20:00] <AlephTwo> It's the simplest solution, hence most likely to work
[20:01] <AlephTwo> You will have to ensure that your on/off switch in the room can override it though
[20:01] <SirLagz> AlephTwo: thaaat's going to be a problem...
[20:01] <AlephTwo> Solution: On/off switch is hooked up to the yun.
[20:01] <SirLagz> I wonder if I could get the Arduino to fail open
[20:02] <SirLagz> the On/Off switch will be what's supplying power to the Fan and arduino
[20:02] <AlephTwo> there'y'go
[20:03] <AlephTwo> power on and then control via web-app
[20:03] <SirLagz> eh true
[20:03] <SirLagz> until the Arduino fails for whatever reason lol
[20:03] <AlephTwo> Shouldn't do.
[20:04] <AlephTwo> If you have it hooked up to ethernet, and also throw in a couple of leads to the spi bus so you can connect directly from a debug port somewhere
[20:04] <AlephTwo> think phone-type socket under the switch or something
[20:04] <SirLagz> I guess as long as the Arduino can survive ~50ish degrees celsius, it should be fine
[20:06] <ant_thomas> Might be an obscure question, has anyone connected a Bluetooth GPS receiver directly to an RPi without using Bluetooth? I'm thinking wired directly over serial somehow.
[20:06] <AlephTwo> ATMega 328 are rated for -40 to +85 C
[20:07] <SirLagz> AlephTwo: cool. That should be fine for my roof cavity then :D
[20:07] <AlephTwo> You could put a thermistor in the yun enclosure and when it gets too hot, trigger a shutdown or warning

[20:08] <SirLagz> so many options
[20:08] <AlephTwo> If it's insulated, it shouldn't exceed 60/70 C up there, unless you are in v. hot climes
[20:10] <AlephTwo> If it does get too hot, then you can just install an extraction fan in the yun case, along with some air holes

[20:15] <SirLagz> AlephTwo: that's only if the tablet is rooted.
[20:15] <FlyingPersian> bust I think tablets have a normal SD slot right?
[20:15] <AlephTwo> you may need root
[20:15] <AlephTwo> Mine has microsd (usd)
[20:15] <SirLagz> FlyingPersian: my tablet has both Normal SD card and Micro SD Card
[20:15] <FlyingPersian> hm I don't have one anymore, gotta check out my mom's
[20:16] <AlephTwo> You may have to find some linux shell tools or similar though. It's all a hypothesis until my tablet boots up

[20:20] <AlephTwo> What about your phone? If you have a (rooted?) android phone, you may be able to do it there, assuming you can drop the image onto your internal storage.
[20:21] <FlyingPersian> nexus 4
[20:21] <FlyingPersian> doesn't fit SD cards
[20:21] <FlyingPersian> I have an old phone with micro sd, but I think I bricked that one a while ago :D
[20:21] <AlephTwo> no microsd slot internally?
[20:21] <FlyingPersian> nope the nexus for doesn't have an sd slots
[20:22] <AlephTwo> No neighbors or friends nearby with any microsd adapters? sd card readers? anything?
[20:23] <FlyingPersian> I'm trying the tablet
[20:23] <Great-Geek> FlyingPersian, If you root the tablet, busybox should have dd (or atleast a stripped-down version)
[20:24] <FlyingPersian> god damn
[20:24] <FlyingPersian> naw it's not my tablet
[20:24] <AlephTwo> You can install TerminalIDE from the store w/o root, but I don't know about permissions to poke at /dev/mmcbln
[20:24] <FlyingPersian> and I can't format the sd card
[20:24] <AlephTwo> Then you are well and truly fucked

[20:28] <AlephTwo> k. You have a cable for tablet?
[20:28] <Great-Geek> FlyingPersian, Don't think of it..
[20:28] <Seckel_> After replacing SD card, my rasp pi is still only sometimes booting :(
[20:28] <SirLagz> Seckel_: bugger
[20:29] <FlyingPersian> why not Great-Geek ?
[20:29] <AlephTwo> If you can enter debug mode & go in over usb, you may be able to access the microsd filesystem
[20:29] <FlyingPersian> I want to install raspbmc
[20:29] <AlephTwo> FlyingPersian: (not your tablet, so don't root it :)
[20:29] <FlyingPersian> yeah the thing is that the tablet is in farsi :D
[20:29] <FlyingPersian> I won't root it
[20:29] <FlyingPersian> I can't read damn farsi
[20:29] <Great-Geek> AlephTwo, FlyingPersian, Android exposes the sdcard over MTP/PTP/fusermount

[20:30] <SirLagz> Seckel_: what's happening when it tries to boot ?
[20:31] <AlephTwo> Seckel_: You could visually inspect the pins in the slot, ensure they all contact

[20:32] <SirLagz> Seckel_: does pushing down on the SD card while it's booting help ?
[20:32] <Great-Geek> FlyingPersian, Root isn't required, you need a custom recovery
[20:32] <FlyingPersian> don't have that as well on the tab
[20:32] <FlyingPersian> only my phone
[20:33] <AlephTwo> Seckel_: Your power supply may be insufficient.
[20:33] <Seckel_> SirLagz: No change :/
[20:33] <Seckel_> AlephTwo: I've tried 4 different PSUs

[20:33] <SirLagz> Seckel_: and different USB cables?
[20:33] <Great-Geek> Seckel_, Dim activity light means it cant read card or p1/start.elf
[20:33] <AlephTwo> Seckel_: Do other pi images work?
[20:34] <Great-Geek> Seckel_, How did you write the image to the card ?
[20:34] <AlephTwo> You may be trying to boot an invalid or corrupt image
[20:34] <AlephTwo> FlyingPersian: I suspect that you'll have to wait until you can get access to a usd reader. I'd go ask the neighbors if they have anything
[20:35] <Great-Geek> Well, a dim ACT light is present up until start.elf is exec'd correctly

[20:38] <AlephTwo> SirLagz: nn o7
[20:39] <Froolap> what is the MD5SUM?
[20:39] <Seckel_> SirLagz: bye!
[20:39] <Great-Geek> Froolap, It's an integrity check
[20:39] <AlephTwo> Froolap: It's a checksum to ensure that the image you downloaded contained all the same bytes, in the same order, as the image online
[20:39] <Great-Geek> Froolap, Even a small difference will result in a different md5sum
[20:40] <AlephTwo> Where you download the image from will usually have a checksum (like 24ea1163ea6c9f5dae77de8c49ee7c03) for their image.
[20:40] <AlephTwo> You download the image, do your own checksum & confirm that the same number is generated
[20:40] <AlephTwo> different == problem
[20:41] <Great-Geek> Also, if you're working on a mounted img, you may want to md5 it before flashing what you think is the original image
[20:42] <Great-Geek> Froolap, Since you plan on making a remix, soak up this knowledge
[20:42] <Seckel_> Great-Geek: Done, but where do I find the original md5sum for the file?

[20:44] <Seckel_> I found it, but when I downloaded it, it was zipped in .gz format. Do i compare the .gz file or the img?

[20:47] <AlephTwo> You want an armv6 I believe
[20:48] <Great-Geek> AlephTwo, Yes, armv6 it is
[20:48] <Froolap> I was just trying to make rpi2b fedora images so that others would be happy. but..... iwhile i can make an image tthat boots, it appears I can't share, so it's pointless.
[20:49] <Great-Geek> Froolap, I made a script just to get around that restriction.
[20:49] <Froolap> it didn't work for me. I couldn't fix it.
[20:49] <Great-Geek> Froolap, I could've made images, easy. But providing support in the long run would be annoying
[20:50] <Great-Geek> Froolap, I found what was wrong with the old script
[20:50] <Great-Geek> Froolap, I forgot to set the proper flags on partition1 there
[20:51] <Froolap> that would do it.

[21:43] <Zunz> I haven o idea where to begin
[21:44] <AlephTwo> https://www.npmjs.com/package/node-core-audio maybe?
[21:45] <AlephTwo> If you want to use imageMagick, then go look here: http://stackoverflow.com/questions/19644249/imagemagick-with-fftw-on-heroku
[21:46] <Zunz> that node core audio looks promising, but it has no fft stuff yet. It's on the todo list of it though
[21:48] <AlephTwo> https://plot.ly/nodejs/ may help you, but it appears to have streaming/fft support for matlab and not nodejs, although I could be missing something

[21:52] <Zunz> I already have the buffer available in nodejs gladly
[21:53] <AlephTwo> go grab the fft lib and see what you can do then :)

[21:54] <AlephTwo> You have the data. Go play with the fft examples and try to pipe it out into a plotting chart
[21:54] <AlephTwo> I'm sure you can ignore that until you want to understand fft better
[21:54] <AlephTwo> To get up & running, it's best to just experiment with the library

[22:08] <AlephTwo> You have a gimbal?
[22:08] <Tagtoo> well, not gimbal per se, it's a 3 axis servo rig
[22:08] <AlephTwo> I have a cheap p/t platform.
[22:08] <AlephTwo> I had it hooked up to an arduino, but I had created a simple serial library for controlling it
[22:08] <Tagtoo> i bought the cheap p/t platform then stuck it on an L bracket to another servo :)

[22:10] <AlephTwo> I was wondering how to grab the websocket camera data with opencv/simplecv. You haven't examined that yet yet?
[22:10] <Tagtoo> not yet.. working in stages
[22:11] <Tagtoo> Sonar, Imu, Gimbal done except for one thign
[22:11] <AlephTwo> You are controlling all the servos from the PI?
[22:11] <Tagtoo> When i pan right or left, the imu values are 45 degrees off
[22:11] <Tagtoo> yes, using the adafruit i2c 16 pwm controller
[22:11] <AlephTwo> Then just throw an offset in
[22:12] <Tagtoo> right
[22:12] <Tagtoo> http://imgur.com/gallery/mzaqv
[22:13] <Tagtoo> The question is the math for camera x y from imu x y ,, how do i apply both iX and iY to cX and offset with cZ

[22:15] <AlephTwo> I'm not sure I understand the question. You have 3 servos controlling the camera, x,y axis, yes. What does the 3rd servo do again?
[22:16] <Tagtoo> 3rd servo is roll
[22:16] <Tagtoo> so when the car tilts left , camera rolls right
[22:16] <AlephTwo> ah.
[22:16] <AlephTwo> You have gyro installed?
[22:16] <Tagtoo> 10dof imu, yes
[22:17] <Tagtoo> working great.
[22:17] <Tagtoo> it's transforming the values when the camera is not pointing straight forward
[22:17] <AlephTwo> You're talking about matrix transformations
[22:17] <AlephTwo> You could cheat...
[22:17] <Tagtoo> -not
[22:18] <AlephTwo> Simplecv, look for a horizon line when you are horizontal. Try to keep the roll so that stays horizontal :)
[22:18] <Tagtoo> good idea :)
[22:18] <AlephTwo> feedback from simplecv > roll-servo

[22:19] <Tagtoo> theres got to be a trig transform i just need to find it i guess
[22:19] <AlephTwo> matrix transformations. good luck
[22:20] <Tagtoo> I will be using opencv at some point.. my wife wants this car to find flowers in the nature preseve in our back yard
[22:20] <AlephTwo> You will have to twiddle the x,y servos whilst playing with roll if you are wanting to keep the picture straight
[22:20] <AlephTwo> You may want to look into using software to rotate the image & just crop a border

[22:22] <Tagtoo> im keeping the picture straight now as long as the camera is facing forward. So I'm good there, it's when i manually pan left right that the imu values need to be transformed, I'm looking at a Vector Transform video now.
[22:22] <AlephTwo> You could just plot the values as you manually control the camera & figure out what's happening
