[1:34] * Bozza (~Bozza@unaffiliated/bozza) Quit (Read error: Connection reset by peer)
[1:34] <pyb0k3h> hey guys, i bought a 16x2 HD44780-compliant LCD display, but it came soldered to a board. So my question is, do I need to remove the board or I can still use the current setup? http://imgur.com/nPbNikj
[1:34] * Bozza (~Bozza@unaffiliated/bozza) has joined #raspberrypi
[1:35] <shiftplusone> it's even better this way
[1:35] <pyb0k3h> over on the right, there are 4 male pins for GND, VCC, SDA, and SCL
[1:35] * arza (arza@unaffiliated/arza) Quit (Ping timeout: 260 seconds)
[1:35] <pyb0k3h> but what are pins SDA and SCL??
[1:35] <shiftplusone> i2c
[1:36] <pyb0k3h> so can i use the code at adafruit to display a message with this current setup?
[1:36] <shiftplusone> the board makes it so that you don't have to use as many pins, it's a parralel to serial piggiback thing
[1:36] <shiftplusone> probably
[1:36] * mdorenka (~mdorenka@unaffiliated/mdorenka) Quit (Ping timeout: 240 seconds)
[1:36] <shiftplusone> just make sure that the pins aren't pulled up to 5V on the board.
[1:37] <pyb0k3h> not sure if i follow you
[1:37] <shiftplusone> where did you get the board?
[1:37] <pyb0k3h> online
[1:38] <pyb0k3h> no paperwork or spec sheet
[1:38] <ShorTie> dah

[1:39] <shiftplusone> see how you go with adafruit code and hope it doesn't fry your pi then.
[1:39] <pyb0k3h> i think this was it: http://www.amazon.com/microtivity-IM161-Module-White-Backlight/dp/B0059H60SK/ref=sr_1_8?s=electronics&ie=UTF8&qid=1392769371&sr=1-8&keywords=16x2+LCD+hd44780
[1:40] <shiftplusone> no mention of a serial backpack on that page
[1:40] * unkzo (~unkzo@unaffiliated/tsar) has joined #raspberrypi
[1:40] <pyb0k3h> https://github.com/adafruit/Adafruit-Raspberry-Pi-Python-Code/blob/master/Adafruit_CharLCD/Adafruit_CharLCD.py
[1:40] <pyb0k3h> this is the library i would be using
[1:41] <pyb0k3h> so it is using RPi.GPIO
[1:41] * gaz_b (~gaz_b@ has joined #raspberrypi
[1:41] <pyb0k3h> not sure how i2C would be involved
[1:42] <gaz_b> hi there, can anyone reccommend a 128GB SD card i can use in a revision B board running raspBMC ?
[1:42] <shiftplusone> https://github.com/adafruit/Adafruit-Raspberry-Pi-Python-Code/tree/master/Adafruit_CharLCDPlate
[1:42] <shiftplusone> gaz_b, bad idea. SD cards aren't made to last or be reliable.
[1:43] <gaz_b> does that go for USB sticks too ?
[1:43] <shiftplusone> USB sticks are quite reliable on the pi
[1:44] <gaz_b> i want to store files locally on my media centre (not stream) , would a 128GB USB stick be better?
[1:44] <pyb0k3h> shiftplusone: so you're saying i should use that LCDPlate libary instead?
[1:44] * arza (arza@unaffiliated/arza) has joined #raspberrypi
[1:45] <ShorTie> or a usb hard drive
[1:45] <shiftplusone> pyb0k3h, I am not saying either. I am just pointing to the i2c version of the library, but it seems to also use the io expander chip and might require modification. I haven't looked into the specifics.

[1:45] * ipsifendus (~edward@c-50-139-32-183.hsd1.or.comcast.net) has joined #raspberrypi
[1:46] <shiftplusone> gaz_b, a hard drive with an external power supply would be ideal.
[1:46] <pyb0k3h> hmm i can't find an example online with that kind of LCD setup, i may just remove the board and go with more wiring i guess
[1:47] * _inc (~inc@unaffiliated/-inc/x-0498339) Quit (Quit: Computer has gone to sleep.)
[1:47] * Bozza (~Bozza@unaffiliated/bozza) Quit (Ping timeout: 245 seconds)
[1:47] <shiftplusone> pyb0k3h, there are some problems with doing that.
[1:47] <pyb0k3h> doing what? removing the board?
[1:47] <gaz_b> mmm, that would moving away from the prtability i need .. ideally a 128GB stick to store files. Ideally ill want to power even the raspberry pi from the USB power from the TV usb ports... ideall no power socket at all .. is taht psosble ?
[1:47] <shiftplusone> the controller is designed for 5v. Although it will work with 3v, you will have contrast issues.
[1:47] * sco` (~ross@unaffiliated/sco/x-3425046) Quit (Ping timeout: 272 seconds)
[1:48] <shiftplusone> If it operates from 3v, the contrast needs to be a negative voltage.

[1:48] * chris_99 (~chris_99@unaffiliated/chris-99/x-3062929) Quit (Quit: Leaving)
[1:48] <shiftplusone> what some people do (Gordon, for example) is hook it up to 5v, but only use 3.3v logic, ensuring that they never try to read anything back from the display
[1:49] <blair449> hello, how can I change the boot of raspbian so that it doesn't load unnecessary services?
[1:49] * mumixam (~m@unaffiliated/mumixam) Quit (Remote host closed the connection)
[1:49] * Artpicre (~Artpicre@unaffiliated/artpicre) has joined #raspberrypi
[1:49] <shiftplusone> The 'right' way to do things is to read the 'busy flag' before sending a command ot make sure it's done with the last one, but what most people do is just wait a little bit after sending the command. That way is a little slower, but works.
[1:50] <shiftplusone> blair449, man update-rc.d
[1:50] <shiftplusone> blair449, or install rcconf
[1:50] * mumixam (~m@unaffiliated/mumixam) has joined #raspberrypi
[1:51] <blair449> what is that shiftplusone?
[1:51] <shiftplusone> a little menu that lets you enable or disable services without doing it manually

[1:54] <pyb0k3h> i just don't know how to setup the wiring with that board attached to the LCD
[1:54] <pyb0k3h> i was going to run this exercise: https://github.com/adafruit/Adafruit-Raspberry-Pi-Python-Code/blob/master/Adafruit_CharLCD/Adafruit_CharLCD_IPclock_example.py

[1:59] * lifelike (~lifelike@d24-57-15-47.home.cgocable.net) has joined #raspberrypi
[1:59] <gaz_b> will running a 128GB USD stick require any more power than is required as standard by the Pi?
[2:00] <shiftplusone> depends on what you mean exactly. The power requirements given assume that you'll have some non-power hungry usb devices plugged in
[2:01] <gaz_b> i guess what i mean is ..is a 128GB USB stick a power hungry device ?
[2:01] <shiftplusone> nope
[2:01] * Geniack_ (~Geniack@unaffiliated/geniack) Quit (Ping timeout: 248 seconds)
[2:02] <gaz_b> will it power from a TV's USB port ?
[2:02] * gbaman (~gbaman@host81-134-114-61.in-addr.btopenworld.com) Quit (Ping timeout: 260 seconds)
[2:02] <shiftplusone> depends on the TV
[2:02] <gaz_b> TV's have different USB 2.0 power output ratings ?
[2:02] <gaz_b> oh, didnt realise that
[2:03] * Moon_Man (~Moon_Man@CPE1040f39b36f8-CM001868d946e0.cpe.net.cable.rogers.com) has joined #raspberrypi
[2:04] <shiftplusone> The pi requires more than 500mA, but there are many devices which operate out of USB specs, so most manufacturers take that into account
[2:04] <gaz_b> ok thanks
[2:04] * jonascj_ (~jonas@ip-52-91.bnaa.dk) Quit (Ping timeout: 265 seconds)
[2:05] <shiftplusone> if we're going by specs, the answer is 'no', but in practice, 'yes'
[2:09] * harish (~harish@ Quit (Read error: Operation timed out)
[2:09] <gaz_b> somebody mentioned i will need to buy a codec licence from raspberry pi to play certain file types aswell ..is this true ?
[2:09] <shiftplusone> yup
[2:10] <shiftplusone> the codec prices aren't bundled into the cost of the hardware as they are with most other devices.
[2:10] <gaz_b> i see

[2:14] * Macuser (~textual@unaffiliated/macuser) has joined #raspberrypi
[2:18] <kevireilly> is it generally recommended to keep pins open or should they be opened and closed on demand? The problem with the latter that I've found is that I can't read the value if I open and close
[2:19] <shiftplusone> what do you mean by open and close?
[2:19] <shiftplusone> input/output?
[2:20] * teepee (~teepee@gateway/tor-sasl/teepee) Quit (Ping timeout: 240 seconds)
[2:21] <kevireilly> having a feeling this may be client specific (node.js pi-gpio) i'm checking out the code now.. seems "open" is doing something like `/sys/devices/virtual/gpio export 17 and then setting the direction to input or output
[2:21] <kevireilly> closing does an unexport
[2:22] * cccy_RegeaneWolf is now known as cccyRegeaneWolfe
[2:22] <shiftplusone> So I guess it uses the kernel module then.
[2:22] <shiftplusone> You should keep it 'open' while your program is running
[2:23] <kevireilly> ah ok, excellent.. thanks shiftplusone

[2:27] <kevireilly> speaking of input versus output, where does one use input instead of output? I'm trying to find an explanation on the googs, but am failing to do so
[2:27] <shiftplusone> input if you want to read a value (like a switch)
[2:28] <shiftplusone> output if you want to output a value (like an LED)

[2:28] <kevireilly> ahh that makes a lot of sense, thanks again
[2:28] <shiftplusone> np
[2:29] <kevireilly> i am using output and an LED presently ;)
[2:29] <kevireilly> i have a switch sitting here that i might as well try now with input
[2:30] <kevireilly> am i remembering wrong or do some switches have 2 or 3 connectors?
[2:30] <kevireilly> i mean, there are both
[2:30] <shiftplusone> a switch needs to be wired correctly (it's not very intuitive)
[2:30] <shiftplusone> and yeah there are lots of different types of switches
[2:31] * Macuser (~textual@unaffiliated/macuser) has joined #raspberrypi
[2:31] <shiftplusone> SPDT (single pole, double throw) would have three contacts, for example.
[2:31] <shiftplusone> 3 pins, rather
[2:32] <kevireilly> ah ok, that might be what i have.. has 3
[2:32] <shiftplusone> is it a button or a switch?
[2:32] <kevireilly> switch, up down
[2:32] <shiftplusone> yeah
[2:32] <shiftplusone> probably spdt then
[2:33] <kevireilly> sweet, that keyword helps

[2:41] <ebswift> is there a way to maintain a static session into raspbian or run a command that isn't session-dependent? if i ssh in, run a process, then kill the console, it kills the whole session, i want something to keep running
[2:41] <shiftplusone> screen
[2:41] <shiftplusone> or tmux
[2:41] <shiftplusone> or in some cases, nohup might be enough.
[2:41] * nx5 is now known as nx5_off
[2:42] <[styx]> I literally just set up screen for irssi
[2:42] <[styx]> working wel so far
[2:42] <ebswift> is that from the client end or on the raspi?

[2:42] <ebswift> oh, nice

[2:43] <ebswift> uh, though 'screen' is a little too generic for google, is there a link or a more specific search term?
[2:43] <shiftplusone> gnu screen
[2:43] <ebswift> cool

[2:44] <shiftplusone> in a nutshell though, apt-get install screen
[2:44] <shiftplusone> when you want to start a session, just run 'screen'
[2:44] * JakeSays (~quassel@chat.thatswhatjakesaid.com) has joined #raspberrypi
[2:45] <shiftplusone> if you get disconnected, you can ssh back in and run screen -x
[2:45] <shiftplusone> and attach back to the session
[2:45] <ebswift> nice, i'll try it now
[2:45] <shiftplusone> the keyboard shortcuts are done this way... you press ctrl+a, let go and then press another key
[2:45] <shiftplusone> so ctrl+a, d will detach
[2:46] <ebswift> this is all at the console right, not in x?
[2:46] <shiftplusone> ctrl+a, c will create another window. you can press ctrl+a, 0-9 to switch between windows.
[2:46] <shiftplusone> yes
[2:46] <ebswift> cool
[2:46] <shiftplusone> when you want to get fancy, you can split the screen and have multiple things going on at once
[2:46] <ebswift> i'm using gspread to report the ip into a spreadsheet by mac address
[2:46] <ebswift> just need one persistent
[2:47] <ebswift> can multiple clients connect to the same screen?
[2:47] <shiftplusone> yeah

[3:48] <pyb0k3h> ok i have this LCD with I2C plate attached and I ran the example code from http://learn.adafruit.com/adafruit-16x2-character-lcd-plus-keypad-for-raspberry-pi/usage
[3:49] <pyb0k3h> seems to work except that the message/text doesn't appear!
[3:49] <pyb0k3h> the cursor blinks at the top right
[3:49] <pyb0k3h> the sample code is for RBG LCD, but i have a monochrome LCD
[3:50] <pyb0k3h> i ran i2cdetect and it shows "27" in the "7" column and "20" row
[3:52] <pyb0k3h> so i modified the sample code's __init__() method by setting addr=0x27 (originally it was set to 0x20)
[3:52] <shiftplusone> the adafruit plate uses an io expander chip, so their code is to control that. And I think your backpack has a microcontroller which passes i2c commands to the LCD. I don't think the library is usable. Although I still think using i2c is easier, if you don't know the controller and you haven't worked with i2c, it may be easier for you to remove the backpack.
[3:52] * killer_prince is now known as lazy_prince
[3:52] <pyb0k3h> btw, i entered 7x27, but I get a syntax error
[3:53] <pyb0k3h> yes that's what frustrating, i can clear the LCD, turn the backlight on and off
[3:53] <shiftplusone> hmm
[3:53] <pyb0k3h> but when i execute the message() method, the text doesn't show up
[3:53] <shiftplusone> tried adjusting contrast?
[3:53] <pyb0k3h> i adjusted the contrast
[3:53] <shiftplusone> k
[3:53] <pyb0k3h> the cursor is visible, it just blinks top right
[3:54] <shiftplusone> ah
[3:54] * DataLinkDroid (~DataLinkD@ has joined #raspberrypi
[3:54] <pyb0k3h> also why is it that i had to set addr=0x27 and not 7x27 like my i2cdetect shows?
[3:54] * Syliss (~Home2@dpncorp1.digitalpath.net) Quit (Quit: Syliss)
[3:55] <pyb0k3h> i did trial and error and used 0x27 and that seems to work (no longer get IO error
[3:55] <pyb0k3h> so im so close to getting it to work
[3:55] <shiftplusone> I don't know, i've only used SPI. Haven't touched i2c yet.
[3:56] <pyb0k3h> i tried 07x27, but get syntax error
[3:58] <pyb0k3h> so if "27" appears in the 7th column and row labelled "20", my address is 7x27, right?
[3:58] <pyb0k3h> im talking about my i2cdetect output
[3:58] <ldunn> I think your address is 0x27 in that case. "0x" is notation that means "this number is in hexadecimal"
[3:58] <shiftplusone> that makes sense
[4:00] <pyb0k3h> im looking at the library, taking a look at the message() function which calls the write() function: https://github.com/adafruit/Adafruit-Raspberry-Pi-Python-Code/blob/master/Adafruit_CharLCDPlate/Adafruit_CharLCDPlate.py
[4:02] <pyb0k3h> so somewhere in the write() function, it isn't matching up with my plate somehow
[4:03] <pyb0k3h> im afraid im a programming noob to know what this write() method does under hood

I thought for sure it was a hardware issue but after replacing all hardware I'm still having issues.

[12:32] <ShorTie> look up the opto-coupler, check the pin out for the led portition of it, that is all you need hooked up to the rPi i would think

[13:40] <knob> So, I setup a reverse ssh to a server I have... which for me is awesome, because 1st, now I can connect
[13:40] <knob> 2nd, I had never done it before
[13:40] <knob> and 3rd, I learned the basics of using key-authentification for ssh
[13:40] <knob> =)
[13:40] <ShorTie> he just wants to be the object that opens the path way to learning
[13:44] <knob> =) awww ShorTie, that's cute! Dude, that could be a marketing tag line

[17:01] <basti> yes

[17:03] <shiftplusone> wouldn't kill your pi, but the pi's ground is connected to the external supply's ground?
[17:04] <basti> it was, when i fried my first pin
[17:04] <shiftplusone> actually, in that circuit it doesn't matter, nevermind.
[17:04] * Albori (~Albori@ has joined #raspberrypi

[17:11] <basti> found it: http://pastebin.com/5jMQu7rJ
[17:13] <gordonDrogon> ok.
[17:13] <gordonDrogon> that indicates that the pins work OK in INPUT mode and that the internal pull-up/pull-down resistors are working correctly.
[17:14] <gordonDrogon> the only way to test output mode is to connect a pin to a 220Ω resistor and then to an LED.
[17:14] <basti> i measured and there is nada
[17:15] <gordonDrogon> sure you're measuring the right pin?
[17:15] <basti> between pin5 and 1
[17:15] * rvraghav93 (~quassel@ has joined #raspberrypi
[17:15] <gordonDrogon> pin5 - assuming this is header pin 5 - that's one of the I2C pins.
[17:15] <gordonDrogon> it's pulled high to 3.3v via a 1800Ω resistor.
[17:16] <basti> header 18
[17:16] * sco` (~ross@unaffiliated/sco/x-3425046) has joined #raspberrypi
[17:16] <gordonDrogon> ok. header 18 is gpio5 (bcm_gpio 24)
[17:16] <gordonDrogon> I'd measure it to 0v (p1:6)
[17:17] <basti> yes. and there is nothing when i set it to high. other pins give me 3.3
[17:17] <gordonDrogon> but it drives high or low, so shouldn't matter.
[17:17] <gordonDrogon> well - I guess it's possible the output driver is blown - I've not seen that before.
[17:17] <gordonDrogon> however there are 2 output drivers - one to drive it high, the other to drive it low.
[17:19] <gordonDrogon> I do find it hard to work out how connecting it to the opto isolator would blow the pin though.
[17:19] <gordonDrogon> unless you mis-wired and connected it to the +5v line directly.
[17:20] <basti> i checked it often enough after i blew my first pin yesterday. there was no mistake
[17:20] <basti> i can take a pic...

[17:56] <shiftplusone> I wrote a script for someone to do that a while back, but can't find it. =/

[18:50] <shiftplusone> I don't see why not.

[19:48] <rigid> in what language is your driver software written?
[19:49] <gordonDrogon> rigid, Heh.. not stackable no. it's all in C using wiringPi.
[19:49] <rigid> hm, doesn't look chainable/stackable
[19:49] * jorge_lo (~anonymous@cpe-74-71-0-246.nyc.res.rr.com) Quit (Quit: jorge_lo)
[19:49] <rigid> ah... C would be "cut & paste" to turn it into a niftyled plugin
[19:50] <rigid> but I admit, the usefulness is a bit limited for a 4x4 matrix. Unless you plan to expand it
[19:50] <gordonDrogon> maybe, but what's the point. that's the only one - there will never be more.
[19:50] <rigid> or you'd like to use it with high level software
[19:50] <gordonDrogon> I already use it with high level software. C and BASIC.
[19:51] <rigid> there would have been a point if you'd known niftyled before you've written the code. Like freely mapping pixels with a GUI
[19:51] <rigid> that's not high level. how do you generate the pixels?
[19:52] <gordonDrogon> plot(x,y,colour);
[19:52] <gordonDrogon> line(x,y,x2,y2)
[19:52] <rigid> yeah... high level would be to use a GIF animation, an .avi file, the cairo API or something
[19:52] * gordonDrogon shrugs.
[19:52] <gordonDrogon> I have no use for that.
[19:53] <rigid> this way, one can reuse the pixel generating software with hardware that doesn't rely on wiringPi
[19:53] <rigid> i see
[19:53] <gordonDrogon> that board relies on wiringPi. it's designed to work on a Pi.

[19:56] <gordonDrogon> basically, I have no interest in putting another layer of software between what I want to do and the hardware. much as it might make it easier for others, there are no others here.
[19:57] <rigid> are you doing PWM with this setup?

[19:57] <gordonDrogon> no. it's not easilly possible with that setup.
[19:57] <gordonDrogon> so each LED is only 8 colours.
[19:57] <rigid> well, if you do a lot of LED stuff, you appreciate the additional layer. It saves lots of time. And also simplifies hardware.
[19:57] <gordonDrogon> I don't do a lot of LED stuff.
[19:57] <gordonDrogon> that's the most complex.

[20:00] <gordonDrogon> rigid, part of the "issue" is that I already have my own very nice library for drawing stuff into a 'framebuffer' it was utterly trivial for me to write the LED driver here then make my library use it. Essentially I have a 4x4 framebuffer that you poke pixels into and the appear on the LEDs.
[20:00] <gordonDrogon> AbbyTheRat, maybe - but you'll need to work out how its interfaces.

[20:01] <rigid> gordonDrogon: niftyled doesn't abstract the drawing layer. It takes a framebuffer and maps it to greyscale values
[20:01] <AbbyTheRat> would there be a manual for that part? I robbed it from a manafured alarm clock <_<
[20:01] <rigid> with colorspace conversion and all the nasty stuff
[20:04] <AbbyTheRat> missing a manuel, is there another way to find out the interface for it?
[20:05] <AbbyTheRat> hmm, how do you mean interface?

[20:24] <basti> they click
[20:24] <gordonDrogon> AbbyTheRat, that indicates it's serial interface of some sort...

[20:26] <gordonDrogon> basti, well you need to measure the current going through the opto isolators, but with a 1K resistor in the way it should be very low.
[20:26] <gordonDrogon> basti, there is something very wrong if a simple resistor + opto isolator is "blowing" gpio pins.
[20:26] <basti> i have nothing to measure current. only volt/ohm etc
[20:27] <gordonDrogon> most multimeters will measure current too...
[20:27] <basti> gordonDrogon, as you can see in the photo, the wiring is correct. the pin was working fine beofre i wired it up.
[20:27] <basti> mine does not
[20:28] <Taylor> is it safe to set up an image in qemu? when flashed to the pi will there be discrepancies/errors or can it boot flawlessly?
[20:28] <shiftplusone> Taylor, works just fine
[20:29] <shiftplusone> hell, the official image is made using qemu chroot
[20:29] <gordonDrogon> basti, I'm at a loss here then. I do not know.
[20:29] <Taylor> alright thanks
[20:30] <basti> i will order a new relaisboard... but i would like to know what happende. anyone want the old one?
[20:30] <gordonDrogon> post it to me and I'll check ;-)
[20:31] <shiftplusone> Why are people saying 'relais' nowadays?
[20:31] <AbbyTheRat> so what could I do to find out what info I need to send? maybe I could wire the other board into something (the pi?) and record what information it's sending?
[20:31] <gordonDrogon> language/typos ?
[20:31] <gordonDrogon> relays.
[20:31] <shiftplusone> at first I thought it was some foreign language thing, but I have seen it too many times now.
[20:32] <basti> it is german
[20:32] <gordonDrogon> AbbyTheRat, that's an idea but it looks like it might be a 5v board - ot 4.5v which is higher than the Pi's 3.3v...
[20:32] <AbbyTheRat> shiftplusone: I'm guessing relays only for some reason thinks the purals should be is, instead of ys?

[20:49] <AbbyTheRat> it's honestly perfect, along with 20v4 display for other informations that I would like to display
[20:51] <pksato> AbbyTheRat: you need to figure out that controller used on this lcd module.
[20:51] <AbbyTheRat> how would I do this?
[20:52] <pksato> put all labels/number printed on board, and search on google/bing/etc
[20:52] <AbbyTheRat> done, no luck
[20:52] <AbbyTheRat> the numbers and stuff is same name as model of the clock I napped it from

[21:03] <pksato> data, sck and stb need to sniffed.
[21:03] <gbaman> what does a user need access to to work with GPIO? Without root?
[21:04] <gordonDrogon> without root - you need something that will open the /sys/class stuff for you and change the ownership, then you use the (slow) /sys/class interface.
[21:04] <gordonDrogon> but you still need root to do that.
[21:04] <gordonDrogon> alternatively you make your program set-uid root.
[21:05] <gordonDrogon> but you can use the gpio program to do all the exports for you in /sys/class before you start your program.
[21:05] <gordonDrogon> so a shell-script with e.g. gpio export 17 in, etc. in it.
[21:05] <AbbyTheRat> okie, thanks, pstato.
[21:05] <gordonDrogon> Id' go for the setuid program and drop root privs after calling wiringPiSetup();
[21:06] <J-e-f-f-A> Hi. I'm building a call screener/blocker and have run into a snag - when I play audio files (wavs) with aplay to the analog 3.5" jack, the pi often hard locks and I have to power-cycle it. I thought I read of fixes going into the kernel months ago, but I'm running the latest everything and still having issues.
[21:06] <J-e-f-f-A> Could I work around that by using a USB sound card?
[21:07] <J-e-f-f-A> (er, 3.5mm jack. lol)

[21:13] <basti> can you swap an installed os from one pi to another without running into problems?
[21:13] <J-e-f-f-A> AbbyTheRat: That looks like a cool LCD. If the clock is still operational, I'd 'sniff' the data pins as others have suggested. - Maybe while in a 'time set' mode while you move the minutes forward/backwards, etc - to view the commands.
[21:14] <basti> i mean the sd card with the os installed on it
[21:14] <AbbyTheRat> the clock design has made it easy for me
[21:14] <J-e-f-f-A> basti: I've done it between v2 machines fine - not sure if there's anything to be concerned when going between v1 and v2 though.
[21:14] <AbbyTheRat> you can set the time directly from a button
[21:15] <AbbyTheRat> could do the whole thing blind so it's no problem.

[21:18] <J-e-f-f-A> AbbyTheRat: Anyways - if you re-connect that display to the clock, then sniff the lines to reverse-engineer the protocol to control it.
[21:20] <AbbyTheRat> sniff? so instead of plugging the pi in directly? so more like clock - |pi - LC Display?
[21:20] <J-e-f-f-A> AbbyTheRat: And/or - trace those signals back to the chip that's driving them - if you get lucky, it would be a standard microcontroller and perhaps the I2c or SPI pins. Who knows.

[21:21] * linuxstb_ (~linuxstb@unaffiliated/linuxstb) Quit (Ping timeout: 260 seconds)
[21:21] <J-e-f-f-A> Well- connect to the clock, and 'sniff' the pins with an o-scope or logic analizer or a program on the pi written to read the pins and 'record' them for your analysis.
[21:21] <AbbyTheRat> basti: ATM Machine, have fun~
[21:21] <basti> hiv virus
[21:22] <J-e-f-f-A> 1234
[21:23] <AbbyTheRat> I don't have o-scope/logic analyizer so will do it with pi when I get ahold of one ... soon I hope <_<
[21:24] <J-e-f-f-A> So I've got my CallerID Logger/Blocker running on one of my PIs, but if I try to play an audio file it hard freezes often... Googles seem to suggest that there -was- a kernel panic issue, but has since been fixed.
[21:24] <J-e-f-f-A> My Q is if a) It's still an issue, and if anyone knows a fix for it, and/or B) Will using a USB Sound Card work around the issue?
[21:24] <AbbyTheRat> huh.. almost sounds like you hit a different issue? a corner case?
[21:25] <J-e-f-f-A> I guess I should hook up a USB->Serial adapter on the serial port pins and see if that's what's happening. :/

[21:42] <J-e-f-f-A> Yeah, I'll try when I get home. I'll also try another v2 Pi with that SD card to see if perhaps there's a hardware issue with the PI itself in regards to Audio playback. - Sometimes it locks up, sometimes it doesn't... On the surface it seems like an interrupt issue to me.
[21:43] <J-e-f-f-A> I'm assuming if it's an overall audio issue with the PI itself, then using a different program to play the wav file won't make any difference either. The google hits I found referenced 'mixing' sounds.

[22:28] <lorenzo> hi! do you think a BlackBerry 5V, 700mA power adapter will be fine?
[22:28] <shiftplusone> could go nicely with some floppy drives
[22:28] <lorenzo> I measured 430mA draw with my current setup
[22:29] <AbbyTheRat> shiftplusone: indeed, sounds like this would do great as a beat part?
[22:29] <shiftplusone> lorenzo, should be fine.
[22:29] <AbbyTheRat> it's as fun watching the ink getting printed as well, it's interesting what's coming out
[22:30] <shiftplusone> AbbyTheRat, yeah, the high seem a bit too screechy.

[22:31] <AbbyTheRat> wouldn't know about the highs.. but then I mentioned it because compared to the floppy and other motor driven music that I've heard.. I could hear the beat much better while witht he others, I could hear the mid range better
[22:32] <local> anyone can explain to me, why DBUS loads service "freedesktop.org.xxxxxx" on my RPi? All my other RPi's doesn't show such log entries within /var/log/syslog. But one RPi seems to load that stuff and I don't know why. I configured through "raspi-config" to use console only, no X !

[22:43] <[Saint]> I can control duration and intensity, I could make longer jingles but I have to do it all manually. No way I've found to convert it automagically.

[22:52] <[Saint]> $50 USD for the above.
[22:52] <[Saint]> I worked it out and addind the same feature set to a pi is (actually impossible, but, close) will cost around %400

[22:53] <[Saint]> *$400, even.
[22:53] <AbbyTheRat> not bad *shrug*
[22:53] <local> AbbyTheRat: please give me a hint, if I am missing something. To my knowledge I did the same configuration on all my RPi's, and only one is showing these strange "DBUS service freedesktop.org.consolekit" lines in /var/log/syslog
[22:54] <AbbyTheRat> local, wish I could but I'm not familier with raspberry yet
[22:54] <AbbyTheRat> although my understanding of the pi is it meant to be cheap learning tool and you only get JUST what you need
[22:55] <[Saint]> Not even quite that. ;)
[22:55] <[Saint]> ...close, though.
[22:55] <AbbyTheRat> so why are you in here? you're a heretic!
[22:56] <[Saint]> In my experience you need to have a very low bar to not need to compromise in /some/ way with this hardware.
