[0:26] <Valduare> gotta buy 3 yokes and this and that and then I have the most money for bullets to get to the first hunting spot :P
[0:28] <rpgw_> Courtest of a unicorn HAT, the lighting in my room now matches the colour temperature of F.Lux on my monitor. :)
[0:32] * GerhardSchr_ (~GerhardSc@unaffiliated/gerhardschr) has joined #raspberrypi
[0:32] <ThePendulum> rpgw_: thanks for the idea :D
[0:33] <ThePendulum> you wrote some middleware for flux, or how do you get them to communicate?
[0:33] <rpgw_> heh no. just manually for now. It certainly gets one thinking about automated lighting...
[0:34] <Xark> Valduare: http://playdosgamesonline.com/oregon-trail.html :)
[0:34] <rpgw_> The unicorn hat can go very bright, but if I put it one 255,255,255 full brightness it seems to crash the pi. maybe because of power.. though I am using an official Pi power supply.
[0:34] <Xark> rpgw_: Likely power.
[0:36] <rpgw_> I want every light in the house to have a pi attached now. :)

[1:48] <StephenLynx> hey, if I wanted a 14 inch screen more or less attached to my rasp, which would be my best options?
[1:49] * Mr_Sheesh (~mr_s@unaffiliated/mr-sheesh/x-0757054) Quit (Remote host closed the connection)
[1:49] <Xark> StephenLynx: You already have the screen?
[1:50] <plugwash> what kind of resoloution? how much do you care about the size?
[1:50] <Xark> StephenLynx: Generally no problem to get a VESA mount, or even just velcro tape RPi on to back of unit.
[1:50] <StephenLynx> I don`t have the screen, doesn`t have to be a high resolution
[1:50] * Hix (~hix@97e0a009.skybroadband.com) Quit (Ping timeout: 276 seconds)
[1:50] * Mr_Sheesh (~mr_s@unaffiliated/mr-sheesh/x-0757054) has joined #raspberrypi
[1:51] <StephenLynx> and the size is not that important either. it can't be as small as a mobile and keeping small to keep cost low would be good
[1:51] * taza (~taza@unaffiliated/taza) Quit ()
[1:51] <plugwash> the cheapest option is probablly to look for used DVI monitors
[1:51] <Xark> StephenLynx: Okay. You can get 720p 7" HDMI, but sounds like you want bigger.
[1:51] <StephenLynx> no
[1:51] <StephenLynx> I want smaller
[1:52] <StephenLynx> HD is overkill.
[1:52] * mechan (~mechan@unaffiliated/mechan) Quit (Ping timeout: 240 seconds)
[1:52] <StephenLynx> but indeed, 7 inches is kind of too small
[1:52] <StephenLynx> I didn`t pay attention when I read the first time
[1:52] * utack (~utack@2a02:810a:83c0:9394:d63d:7eff:fedb:b2eb) has joined #raspberrypi
[1:52] <Xark> :)
[1:53] <StephenLynx> there isn't people selling this kind of component? generic displays so you can assemble some sort of box?
[1:53] * Mr_Sheesh (~mr_s@unaffiliated/mr-sheesh/x-0757054) Quit (Remote host closed the connection)
[1:53] <StephenLynx> or there isn;t enough demand to justify mass production?
[1:54] <Xark> I got one of these and it is pretty crisp and works nicely with several sources (but not that cheap) -> https://www.adafruit.com/products/1033
[1:54] <StephenLynx> the problem is that this is a monitor, I want something to go inside a box.
[1:54] <Xark> Look at the other options there https://www.adafruit.com/categories/336
[1:55] <Xark> ...or for all sizes https://www.adafruit.com/categories/506
[1:55] <StephenLynx> hm, some are intersting to me, thanks for the tip
[1:58] <plugwash> There are also ebay sellers selling converter boards to connect laptop screens to DVI

[5:17] <sir_galahad_ad> oh excellent
[5:18] <sir_galahad_ad> the new thing here is that to link with wiringPi
[5:18] <sir_galahad_ad> you have to add -lwiringPi to the command line
[5:18] <Electronized> sir_galahad_ad: Oh I see

[5:20] <Electronized> sir_galahad_ad: I am using writing it on Windows because I am used to the Windows tools I have set up

[5:21] <Electronized> sir_galahad_ad: Oh I see, interesting.
[5:21] <methuzla> you can do something like setup a samba share on the pi and work in an editor on the pc
[5:22] <methuzla> but, yeah, easiest to just compile native
[5:22] <Electronized> methuzla: What is a samba share?
[5:22] <Electronized> methuzla: Could I write the code on my Windows machine and compile it on Debian Linux?
[5:22] <methuzla> all kinds of ways of doing this
[5:23] <sir_galahad_ad> Electronized: you'd wanna compile it on your raspian
[5:23] <methuzla> yes
[5:23] <Electronized> Oh alright so that will work :)
[5:23] <Electronized> How do I get WiringPi working?
[5:24] <sir_galahad_ad> you can set up g++ to work as a 'cross compiler' which will compile programs for other architectures, but if i recall it's a bit of a process to get used to.
[5:24] <methuzla> yeah. don't go there.
[5:25] <methuzla> start simple and do what sir_galahad_ad has explained to you above
[5:25] <Electronized> sir_galahad_ad and methuzla oh so I can't get it to compile wiringPi unless I am using an ARM architecture machine?
[5:25] <Electronized> methuzla: "you can set up g++ to work as a 'cross compiler' which will compile programs for other architectures, but if i recall it's a bit of a process to get used to."
[5:26] <Electronized> ?
[5:26] <methuzla> not without much much much difficulty (this is called cross compiling)
[5:26] <Electronized> methuzla: Oh interesting
[5:27] <Electronized> So what do I get once wiringPi is compiled?
[5:27] <methuzla> compiling means turning source code into machine code SPECIFIC TO AN ARCHITECTURE (like X86, ARM, AVR, etc.)
[5:27] <Electronized> An object file?
[5:27] <methuzla> your windows machine is most likely X86
[5:27] <methuzla> pi is ARM
[5:27] <methuzla> arduino is AVR (uno at least)
[5:28] <sir_galahad_ad> your best and simplest bet is to compile your programs 'natively' which is to say on the machine of the same type that they're designed to run on.

[5:32] <plentypaprika> on what level of difficulty does hosting a website on a rasbpi fall under?
[5:32] <methuzla> as in link the wiringpi library that is already installed and ready to go on the pi

[13:33] <Sonny_Jim> Yeah this is for my SNES thingy again
[13:34] <Sonny_Jim> It's going into a pair of shift registers, I forget the number
[13:34] <Sonny_Jim> 4021? something like that
[13:34] <Sonny_Jim> I did have a chip that would do it and had a direction pin but I've lost it in my notes...

[13:37] <Sonny_Jim> Here's the difference with mine, I send out the cotrller inputs to the NES/SNES
[13:37] <Sonny_Jim> The 4021s sit on the NES<-> Pi interface and are loaded up by the GPIO
[13:38] <Sonny_Jim> CLK from the NES is dealt by the 4021s, meaning it's a lot easier for me to hit the latches
[13:38] <gordonDrogon> ah, right. So the Pi is pretending to be the joystick buttons.
[13:38] <gordonDrogon> https://www.adafruit.com/products/395
[13:38] <Sonny_Jim> I've tried before and it's not fast enough to clock out the data itself
[13:38] <Sonny_Jim> It should be very easy to clock in the data, as you've done, then put it into the 4021s ready for the NES to pick up
[13:38] <Sonny_Jim> The CLK is fast but the latches are only 50/60Hz
[13:39] * fiveflowerzz (fiveflower@ has joined #raspberrypi
[13:39] <fiveflowerzz> Hi!
[13:39] <Sonny_Jim> I mean, when clocking the data out of the pads into the Pi, I can do that in the interval between receiving a latch from the NES and the next one
[13:40] <Sonny_Jim> Also o the prowl for a programmable oscilator so I can switch between the PAL/NTSC clock speeds (21MHz ish)
[13:40] <fiveflowerzz> With the new Raspbian Jessie Lite, what's the place to set WIFI name & password? in which config file?
[13:40] <fiveflowerzz> --> headless cmputer, I never use X window

[13:40] * elsevero (~elsevero@ Quit (Quit: elsevero)
[13:40] <fiveflowerzz> i.e. only from command line
[13:40] <Sonny_Jim> Can that go up to 21MHz though?

[13:40] * elsevero (~elsevero@ has joined #raspberrypi
[13:41] <gordonDrogon> Sonny_Jim, it could- would have to change the input clock to the divider though.
[13:41] <Sonny_Jim> Yeah I had a chip like that, except it was DIP and had 16 channels
[13:41] <fiveflowerzz> I even don't remember from Wheezy ;)
[13:41] <fiveflowerzz> gordonDrogon : where do you usually set this?

[13:43] <Sonny_Jim> Actually the datasheet is here:
[13:43] <Sonny_Jim> http://www.ti.com/lit/ds/symlink/sn74lvc245a.pdf
[13:43] <gordonDrogon> Sonny_Jim, yes, the 245 will work, but you need to set the direction.
[13:44] <Sonny_Jim> Sure, that's the good thing about it, there's a few signals I need to read into the Pi from the SNES/NES
[13:44] <gordonDrogon> fiveflowerzz, I've no idea about jessie - I use static IP addresses in my network so also use /etc/network/interfaces
[13:44] <Sonny_Jim> ie latch
[13:44] <Sonny_Jim> Frmo what I remember, I run the 245 at 3.3v and it'll accept 5v
[13:44] <gordonDrogon> Sonny_Jim, can I just clarify - you're making the Pi pretend to be the joystick?
[13:44] <Sonny_Jim> Yeah I've done it already, this is the second version
[13:44] <gordonDrogon> ok
[13:45] <Sonny_Jim> Previous one just pertended to be a joystick
[13:45] <Sonny_Jim> This one will read in the SNES joystick then send it to the SNES
[13:45] <Sonny_Jim> So I can record games, lack of entropy for the PRNG makes this work :)
[13:45] <gordonDrogon> right - so the Pi is in-between a real joystick and the real game.
[13:45] <Sonny_Jim> Yup
[13:45] <gordonDrogon> ok, neat.
[13:46] <Sonny_Jim> As I said, I reckon I'll have enough time between the console latchs to read in the controller and load up the 4021s
[13:46] <gordonDrogon> so joystick to Pi is "solved" and you've already done Pi to NES ...
[13:46] <Sonny_Jim> Yup
[13:46] <Sonny_Jim> Well, it'll be SNES, but the protocol is the same
[13:46] <gordonDrogon> more buttons?
[13:46] <Sonny_Jim> yup
[13:47] <Sonny_Jim> I *may* even go for a 2player version this time
[13:47] * mythos (~mythos@unaffiliated/mythos) Quit (Ping timeout: 245 seconds)
[13:47] <Sonny_Jim> I'm going to hide the Pi in the snes case and stick a Wifi stick in it :)
[13:47] <Sonny_Jim> Got lots of good plans for this one
[13:47] * qubitnerd (~neutrino@unaffiliated/electron/x-8286743) has joined #raspberrypi
[13:47] <Sonny_Jim> The 'best' way would be to use an MCU in between the console and Pi to handle the clocking out of data into the console, but I'm lazy
[13:48] <gordonDrogon> I think i'd not "clock" data into the console.
[13:48] <Sonny_Jim> Well, what I mean is that the joystick clock sent from the console is way too quick for the Pi to read on GPIO
[13:48] <gordonDrogon> what I'd so is make a joystick using the same circuit that's in a joystock - ie. the shift register, then on the inputs to the SR use optoisolators which can be turned on/off by the Pi.
[13:48] <Sonny_Jim> So you need either 4021's or an MCU to handle that CLK
[13:48] * randssd (~randssd@unaffiliated/randssd) has joined #raspberrypi
[13:48] <gordonDrogon> or not look at the clock at all.
[13:49] <gordonDrogon> so the Pi is bridging switches.
[13:49] <Sonny_Jim> Yeah for reading in the joysticks I'm using a CLK from the Pi
[13:49] <Sonny_Jim> The CLK from the console is handled by the 4021's
[13:49] <randssd> has anyone used an .ISO and converted it to .IMG for an Ubuntu Mate install on a Pi 2
[13:49] <gordonDrogon> thats fine - solved - but Pi to SNES - make the Pi be switches not a shift register emulator. ie. have a real shift register in there.
[13:50] <Sonny_Jim> Yeah, that's what I do ;)
[13:50] <Sonny_Jim> The Pi just isn't quick enough on the GPIO to emulate one, hence why other people go for an MCU
[13:50] <Sonny_Jim> an MCU would mean I could support other console joystick protocols, but I'm not too bothered about that for now, maybe v3
[13:51] <gordonDrogon> you could do this with one joystick - have the pi read the switches in 'record' mode, then push the switches (via opto isolators) in playback mode.
[13:51] <Sonny_Jim> Hmm
[13:51] <Sonny_Jim> Problem being there, is that the 4021s are in the controllers
[13:51] <Sonny_Jim> So to 'push' the switches, I'd need to run 12 lines up to the controllers
[13:51] <gordonDrogon> yes.
[13:51] * Hix (~hix@97e0a009.skybroadband.com) has joined #raspberrypi
[13:52] <gordonDrogon> and those same lines read the switches in record mode.
[13:52] <gordonDrogon> although - erm - you might need 12 more ...

[13:52] * gordonDrogon ponders
[13:53] <randssd> can you do an install on the Pi 2 from a USB thumb drive instead of the MicroSD card?
[13:53] <Sonny_Jim> I could read 2 joysticks with 3x245s (12 buttons x 2)
[13:53] <Sonny_Jim> I'd need 4x4021's
[13:54] <Sonny_Jim> It would like a bit 80's old skool but it should work
[13:54] <gordonDrogon> randssd, not easilly you still need to boot off the SD.
[13:55] <gordonDrogon> I presume the snes controlles have 2 x 4021' in them?
[13:55] <Sonny_Jim> yup

[14:02] * timtaler (timtaler@harpy.gmake.de) has joined #raspberrypi
[14:03] <Sonny_Jim> 12 out to set the register up, one in to read the latch from the console
[14:03] <Sonny_Jim> so 26 to send 2 player data to the console
[14:03] <Sonny_Jim> To read the sticks, it's CLK + LATCH out and 1 data in
[14:03] <Sonny_Jim> that's another 6
[14:03] <Sonny_Jim> so 32?
[14:04] <gordonDrogon> doing it that way - probably yes.
[14:04] <Sonny_Jim> I'll lay out a schematic later, it'll make more sense then ;)
[14:04] <gordonDrogon> I still think it's possible to sense and send with one gpio pin on the Pi, so 12 pins per controller - maybe one for direction.
[14:04] <Sonny_Jim> You can see why people go the MCU route, a lot less GPIO/chips
[14:04] <gordonDrogon> that's not clocking anything anywhere at all.
[14:05] <Sonny_Jim> I've tried bit banging the data to the console and I couldn't get it to work
[14:05] <Sonny_Jim> Although I do have access to a bus pirate so maybe I can give it another go
[14:05] <gordonDrogon> I'd not do that either. although using an ISR on the Pi to sample the clock should work.
[14:05] <Sonny_Jim> It would drastically cut down on the amount of chips/GPIO I would need

[14:06] <Sonny_Jim> I think it's worth another go, considering I know a bit more than I did 2 years ago when I first tried
[14:06] <Sonny_Jim> Let me go look up the timing for the CLK
[14:07] <Sonny_Jim> I mean, if I was bit banging, I would only need 3 per player to send and 3 per player to read
[14:08] <gordonDrogon> you'd need 4 chips per controller in my scheme though. I can see that might be an issue if trying to keep it small & simple.
[14:08] <Sonny_Jim> Well, the plan is to go with DIP/breadboard, then switch to SMD once I know it's working good
[14:08] <Sonny_Jim> There's just about enough space in the case to fit a Pi2 and a small interface board
[14:09] <Sonny_Jim> Yeah it's 12us between clocks
[14:09] <Sonny_Jim> I remember running the numbers before and not being able to get the Pi anywhere near close to that
[14:09] <Sonny_Jim> http://www.gamefaqs.com/snes/916396-super-nintendo/faqs/5395

[14:10] <Sonny_Jim> https://raw.githubusercontent.com/SonnyJim/snesbot/master/snesbot_schematic_v1.png
[14:10] <gordonDrogon> ah. 15�S was what I meansured the fastest ISR time using wiringPi.
[14:11] <Sonny_Jim> Ok, so I can definitely scratch bitbanging the console from the Pi GPIO
[14:12] <Sonny_Jim> Maybe I can use a 16bit shift register to cut down those chips in half
[14:12] <Sonny_Jim> ie replacer the 2x4021's with a proper 16bit one
[14:13] <gordonDrogon> for the button emulator it would work - a pair of 595's.
[14:13] * Sonny_Jim nods
[14:13] <gordonDrogon> or a single 16-bit one but I don't know offhand if there is such a thing.
[14:13] <Sonny_Jim> I'll still need a monster load of level shifters for the GPIO

[14:15] <Sonny_Jim> Depending on how long between the 1p and 2p latches, I might be able to just have on set of shift registers to feed the console
[14:15] <gordonDrogon> joystick into Pi - run the joystick at 3.3v - that worked for me on the old NES controllers. Pi to SNES is the issue - that's when you need a �C pretending to be the 4021 shift registers or you use real 4021's with 12 outputs from the Pi.
[14:16] * Sonny_Jim nods

[14:19] * elsevero (~elsevero@ has joined #raspberrypi
[14:19] <Sonny_Jim> Well, I was thinking mpc23017 into a 674
[14:20] * megaztar (~melissast@unaffiliated/melissastar) Quit (Quit: megaztar)
[14:20] <gordonDrogon> you'd need to work out the timind over the I2C bus to see if it's fast enough to simulate the minimum button push time on the controller. (work that out too by working out the sample cycle time - unless the controller has a built in mimimum to eliminate switch bounce.
[14:21] <Sonny_Jim> Well, I'm just setting up a register

[14:21] <gordonDrogon> I have successfully multiplexed 128 LEDs over the I2C bus on the Pi using 3 mcp23017's though on I2C.
[14:21] <Sonny_Jim> Yeah I think this is the way to go
[14:22] <Sonny_Jim> The only issue I can see with this setup is that controller inputs will be one frame behind
[14:22] <gordonDrogon> wiringPi supports the mcp23017 but only in pin at a time mode.

[14:24] <gordonDrogon> only use the ls674 if the console will talk to it in the same way as the 4021's.
[14:24] <gordonDrogon> otherwise use 2 x 4021's.
[14:24] <Sonny_Jim> Yeah I figure it *should* as long as I match the electrical characteristics
[14:24] * qubitnerd (~neutrino@unaffiliated/electron/x-8286743) Quit (Ping timeout: 260 seconds)
[14:24] <gordonDrogon> note tha the 23017 will be powered from the 5v controller side, but that's OK over the I2C bus as the Pi is the master and driving it at 3.3v.
[14:25] <Sonny_Jim> I'm pretty sure I've seen controllers use a 674 in place of 4021's
[14:25] <gordonDrogon> ok - saves a chip if works.
[14:25] <Sonny_Jim> tbh I'll grab both and test
[14:25] <gordonDrogon> you can crank the I2C bus speed up to 800Khz too - the 23017's will go to 1.5Mhz, but I've never been able to get a Pi stable at that speed - the signals are very yukky.
[14:26] <Sonny_Jim> Well, all I need to do is transfer 32bits of data in under 60Hz
[14:26] <Sonny_Jim> So what's 60Hz in ms?

[14:29] <gordonDrogon> if you use register mode on the 23017's it'll fly. even pin mode (via wiringPi) would be fast enough I think.
[14:29] <ScrumpyJack> good afternoon
[14:30] <gordonDrogon> you could crank up the read speed on the controllers to see how fast they'll go too - however being 1/60th of a second behind probably isn't going to be an issue - I doubt anyone has reactions faster than a TV can update...
[14:30] <Sonny_Jim> Sure
[14:30] <Sonny_Jim> I may have to do some off by one juggling when it comes to playback time though

[15:10] <Furtt> Hi guys ! I m trying to connect to my raspberry pi with my pc, directly via an ethernet cable. And I set up a static ip address on my pi, but i can t connect to it. Any idea how to do it or what could possibly be wrong?
[15:11] * jayden (~jayden@blk-89-208-84.eastlink.ca) Quit (Quit: Leaving)
[15:11] <mlelstv> the PC has a static address too?
[15:11] <Furtt> Yes. I set it up manually
[15:11] <mlelstv> is that a cross cable ?
[15:12] <Furtt> Actually I don t know
[15:12] * averagecase (~bolle@cl-3825.cgn-01.de.sixxs.net) Quit (Ping timeout: 252 seconds)
[15:12] <mlelstv> usually you cannot just connect two computers via Ethernet cable. You need a Hub or Switch in between.
[15:13] <mlelstv> only if both sides support it, they can autodetect and work with a straight cable. For Gigabit Ethernet that's standard, but for 100Mbit it is not.
[15:13] <mlelstv> in that case you need a crossed cable (or a hub/switch)
[15:14] * duckpuppy (~patrickai@ Quit (Ping timeout: 256 seconds)
[15:14] <Furtt> what the difference between a crossed cable and a normal ethernet cable?
[15:14] <mlelstv> that's what it says, the wires are crossed.
[15:15] <mlelstv> saying this, the RPI does this autodetection (called MDI-X), but your PC may not.
[15:15] <pksato> most ethernet nic auto sense cable, not need to be cross.

[16:09] <t3chguy> as in, usage of them, I know almost nothing about their internals
[16:09] <t3chguy> though I will eventually learn
[16:10] <Polymorphism> I would like to use the 1:6 star configuration but I'm wondering if the 6 devices in the star can receive packets as well as send them to the central point

[16:10] <t3chguy> Yeah
[16:10] <t3chguy> but if you're doing that
[16:10] <t3chguy> you're best off using RF24-Mesh
[16:10] <Polymorphism> I have 6 modules connecting to one module
[16:10] <t3chguy> http://tmrh20.github.io/RF24Mesh/
[16:10] <Polymorphism> they report data back to it
[16:10] <Polymorphism> but occasionally they will need to request data as well
[16:10] <t3chguy> ah, no need to communicate to each other?
[16:10] <t3chguy> Mesh might still be handy
[16:11] <Polymorphism> no need to talk to each other, just back and forth between the main hub
[16:11] <t3chguy> that way, lets say X is your "Master", 1-6 are your "Nodes"
[16:11] <t3chguy> if 6 is out of range of X, but can see 5, and 5 can see X, then 6 could send data via 5 back to X
[16:11] <Polymorphism> I see
[16:11] <t3chguy> "Requesting Data" is simply sending a payload that the Master replies to
[16:11] <t3chguy> you can reply within the ACK, or you could reply in a following transmission
[16:12] <t3chguy> ACK replies will be more size-limited
[16:12] <Polymorphism> I don't need to send a lot of data
[16:12] <Polymorphism> in fact, it will only be a single string and a single int or float usually
[16:12] <Polymorphism> this sounds perfect
[16:12] <t3chguy> so you could program the Master, that if it sees a specific Byte appear, then it treat it as a request for something
[16:12] <Polymorphism> and fascinating
[16:12] * eripa (~eripa@h-75-7.a183.priv.bahnhof.se) has joined #raspberrypi
[16:12] <t3chguy> RF24Mesh is very handy incase you are using them over range and can't be certain of them all being in range at the same time
[16:13] <t3chguy> it also manages the auto-provisioning, using a system based very simply on DHCP
[16:13] <Polymorphism> but I could do the 1-6 without mesh?
[16:13] <t3chguy> You could
[16:13] <Polymorphism> is mesh harder to use and setup
[16:13] <Polymorphism> I already have the library installed when I installed rf24
[16:13] <t3chguy> its probably easier to set up for multiple modules

[16:17] <Polymorphism> ok here is my dilemma
[16:17] <Polymorphism> as I started drawing this all out
[16:17] <Polymorphism> I realized, what if the control module boots up before the controller pi
[16:17] <Polymorphism> it has to run stand alone, have fallback settings, and then be able to send out a request for updated settings
[16:17] <Polymorphism> so that 1-6 point needs two way
[16:18] <t3chguy> RF24Mesh is two way
[16:18] <Polymorphism> the sensor also needs two way in that it would be ideal to not just wait for updates, but be able to request them as well
[16:18] <t3chguy> well, multi-way

[16:59] <gordonDrogon> wondering if arduino + nRF24L01 would be a better solution for some stuff I'm doing than Pi + Wi-Fi ... (with a Pi acting as a master node)
[17:00] <t3chguy> gordonDrogon: probably :P
[17:00] <ThePendulum> I take it overclocking the Pi in Turbo mode is considered fairly safe?
[17:01] <gordonDrogon> might get a few to have a play.

[17:03] <t3chguy> gordonDrogon: 3v3 input voltage, but data is 5v tolerant
[17:03] <t3chguy> some Arduino 3v3 regs struggle to drive them when receiving data
[17:03] <t3chguy> but a decoupling cap often solves that
[17:04] <gordonDrogon> I'd make a custom board with an 8Mhz ATmega on-board anyway, so I can use a decent 3.3v regulator.
[17:04] <swift110-phone> Good morning
[17:04] <gordonDrogon> 6 for a tenner on amazon.
[17:05] <t3chguy> gordonDrogon: yeah, they're pretty cheap
[17:05] <t3chguy> there are some on the net with a built in MCU
[17:05] <GreeningGalaxy> can anyone tell me how to temporarily mount an SD card read-only? I'm trying to make a backup image with dd and I don't have a way to connect the SD card to anything besides the pi right now
[17:05] <t3chguy> those you could use entirely without an Arduino
[17:05] <shauno> although, mine are odd. I have two that have been going since the start of december. one shows the battery has dropped 0.02V, the other has *gained* 0.1V
[17:05] <t3chguy> gordonDrogon: you could always just use an ESP8266, with its Wifi connectivity
[17:05] <gordonDrogon> t3chguy, learning curve.
[17:06] <t3chguy> then you'd need no MCU, and your Master would need no additional hardware
[17:06] <t3chguy> gordonDrogon: the ESP can be programmed in Lua, or C
[17:06] <t3chguy> (C being your favourite)

[17:06] <t3chguy> gordonDrogon: here you go http://www.esp8266basic.com/
[17:06] <t3chguy> its Basic friendly apparently xD
[17:07] <mgottschlag> ... or just port your basic dialect to Xtensa :)
[17:07] <Chillum> basic!!! ugh
[17:07] <Chillum> I learned that when I was 8
[17:07] <GreeningGalaxy> I did see some instability with OC'ing to 1000 MHz with no overvolt, but I get the idea that being able to go that high at all with no overvolt means I did pretty well
[17:07] <Chillum> it took 20 years to unlearn the bad habits!
[17:07] <shauno> I believe there's an arduino core for the 8266 too, which makes the learning curve near-zero
[17:07] <gordonDrogon> lucky you - I didn't find out about it until I was 14 or 15.

[17:07] <t3chguy> thats what I currently use
[17:08] <Chillum> gordonDrogon: bad languages encourage bad habits... I never had a teacher
[17:08] <gordonDrogon> Chillum, lets not forget that Apple and Microsoft started with BASIC - as did Eben ...
[17:08] <Chillum> it has a long and rich history
[17:08] <Chillum> and is a terrible language!
[17:08] <gordonDrogon> Chillum, anyway, I like my basic. I'l sticking with it.
[17:08] * BurtyB still has a M$ gwbasic book on the shelf :)
[17:08] <shauno> and more importantly, so did I :)
[17:09] <Chillum> okay, to each their own
[17:09] <gordonDrogon> my basic is written in C, however...
[17:09] <Chillum> basic on a mcu is just... wrong
[17:09] <Chillum> just put php on there and be done with it ;lol
[17:09] <gordonDrogon> I did see some terribly python yesterday though. just goes to show you can write FORTRAN in any language.

[17:10] <Chillum> I know
[17:10] <Chillum> pic basic is not something I have ever used so I can't really pontificate on that
[17:10] <Chillum> I assume it is better than normal basic somehow
[17:10] <gordonDrogon> I've never used it either, however it's out there...
[17:11] <gordonDrogon> just like VB ...

[17:11] <Chillum> most of what is written in it is so bloated and unstable
[17:11] <gordonDrogon> that may be so, but it's out there and there are millions more projects still being developed in it.
[17:11] <Chillum> so is syphilis
[17:11] <mlelstv> vb.net has the advantage that every windows has it.
[17:12] <Chillum> just like explorer!
[17:12] <mlelstv> miles ahead of using command or even powershell.
[17:12] <gordonDrogon> Chillum, well, whilt trying to keep this family friendly (you tell the 8 year old what that is), getting both can be lots of fun...
[17:12] <mlelstv> but you cannot script explorer :)
[17:12] <Chillum> lol
[17:13] <Chillum> I have found that using toy languages is fun and has an easy learning curve. But it makes using proper languages far more difficult in the future because of the bad design habits the toy languages encourage
[17:14] <mlelstv> every language is a toy language
[17:14] <Chillum> thus I would recommend them for people who have already learned to program and want some fun, but not to learn programming
[17:14] <gordonDrogon> basic is not a toy language. try telling bill gates that his mllions were based on a toy language...

[17:15] <Chillum> Gates made $$$$ making some of the worse software in history, bad example
[17:15] <GreeningGalaxy> doesn't 'toy language' just mean not Turing-complete?
[17:15] <gordonDrogon> an example of a modern basic: http://unicorn.drogon.net/snake.rtb
[17:15] <Chillum> pretty much all languages are turing complete
[17:15] <mlelstv> no language is turing complete, because none runs on an infinitely large computer :)
[17:16] * Chillum halts this discussion before the halting problem sets in
[17:16] <GreeningGalaxy> ah, nevermind, wiki says toy languages are Turing-complete generally
[17:17] <mlelstv> you rarely use lesser languages. But sometimes you do, to be able to proof their correctness.
[17:17] <GreeningGalaxy> then again, wiki page on that is totally uncited.
[17:17] <mlelstv> I've seen such things for real-time systems.
[17:17] <GreeningGalaxy> er, unsourced.
[17:17] <gordonDrogon> I did look at writing a run-time for my basic to run on an atmega - essentially take a procedure/function in your main program and auto down-load it into an atmega at program run-time.
[17:19] <gordonDrogon> the old 8K basics were tough on 8-bit micros. I didn't have the energy to complete the atmega run-time part of it iall.
[17:19] <ThePendulum> hmm, I reckon it's a bad idea to developer right on my Pi like I do with my servers
[17:19] <ThePendulum> browserify taking 20 seconds per change, lol
[17:19] <ThePendulum> -er
[17:19] <mlelstv> browserify?
[17:20] <ThePendulum> yeah, a bundler for JS
[17:20] <Chillum> compiling on a pi reminds me of compiling when I was young
[17:20] <Chillum> https://xkcd.com/303/
[17:20] <mlelstv> last year then? :)
[17:20] <gordonDrogon> I develop directly on Pi(s).
[17:21] <ThePendulum> haha
[17:21] <ThePendulum> gordonDrogon: I do now... not sure how long I'll keep it up
[17:21] <Chillum> mlelstv: I am young at heart
[17:21] <gordonDrogon> My stuff is mostly pure C compiling though - that's fast enough.
[17:22] <mlelstv> when I was young you had 8bit micros. In that time a pi would have been the worlds fastest supercomputer.
[17:22] <gordonDrogon> wiringPi is getting bigger though - it now takes a few seconds more than it did.
[17:22] <Chillum> mlelstv: I started at the age of 7 with VIC-20
[17:22] <gordonDrogon> I was part of a team that built the worlds fastest supercomputer... once upon a time...
[17:22] <Chillum> to give a hint at my age
[17:23] <mlelstv> shall I call you grasshopper? :)
[17:23] <gordonDrogon> vic-20 - 1980. 7 years old, now 43...
[17:23] <shauno> I started on 8-bit ataris (600xl, 800, etc). I still have a softspot for anything that gives you "READY" <2 seconds after you hit the power switch

[17:50] <Valduare> ah you have digitaly addressable led strip
[17:50] <t3chguy> ali1234: really? Wonder why
[17:50] <ThePendulum> yeah
[17:50] <t3chguy> I have 4 MicroSDs on their way to me anyway
[17:50] <ali1234> the usbbootcode.bin hangs when you upload it
[17:50] <ali1234> you can run other stuff though
[17:51] <ali1234> but you can't do much with raw GPU assembly due to lack of documentation
[17:51] <t3chguy> :/
[17:51] <t3chguy> well maybe the .bin simply needs an update
[17:51] <ali1234> we disassembled it and it appears to have very different branches depending on the cpuid
[17:52] <ThePendulum> I got a reel with another 160 LEDs as well, but a different chip
[17:52] <ThePendulum> I should see if I can hook up both at once
[17:52] <ali1234> yes, it needs an update
[17:52] <ThePendulum> I don't think the Pi is powerful enough to control them both though
[17:52] <ali1234> only the foundation can do that though
[17:52] <t3chguy> ali1234: thats not the end of the world then
[17:52] <ThePendulum> I need to get a Pi 2
[17:52] <t3chguy> ali1234: where can we pester them xP
[17:52] <ali1234> there is probably enough documentation available to rewrite it

[18:30] <gordonDrogon> yes - I think you've broken them.
[18:30] <GreeningGalaxy> every microSD/SD slot I've encountered that clicks like that doesn't hold onto the card and will let you pull it right out
[18:31] <GreeningGalaxy> I guess I've never seen a non-broken one then :V
[18:31] * MiningInc (~MiningInc@gateway/vpn/privateinternetaccess/mininginc) has joined #raspberrypi
[18:31] <gordonDrogon> and every one I've had that's clicked hold on to it. (sample size 2)
[18:32] <t3chguy> ali1234: unlikely that I have 7 that have been like that since I got them
[18:32] <GreeningGalaxy> are you sure it's holding onto it? they're designed to provide a bit stronger friction fit when clicked in than when clicked out, but it shouldn't be enough to stop you from pulling it (and doing so shouldn't cause any damage)
[18:32] <ali1234> t3chguy: right, they probably weren't broken when you got them
[18:33] <ali1234> but they are now
[18:33] <mgottschlag> also, 50% of the clicky ones won't release the card either even if operated correctly.
[18:33] <MiningInc> is swap size of 1024 too big? I only ask as I am unfamiliar and it was at 100, but was advised to increase size to 1024...seems a bit much
[18:33] <t3chguy> alright ali1234 - I'll test on a Brand new and sealed SEEEDStudio Ethernet Shield
[18:33] <ali1234> by "test on" you mean "break" right?
[18:33] <MiningInc> running on pi 2 , raspbian
[18:34] <gordonDrogon> MiningInc, you may not need any swap... depends what you do.
[18:34] <GreeningGalaxy> my pi's SD slot definitely has nothing that could hold onto the card. the card does have a notch for such, but there's a little hole in the slot right above that notch and I can see that there's nothing there to grab it
[18:35] <t3chguy> ali1234: are they literally that easy to break?
[18:35] <ali1234> apparently
[18:35] <MiningInc> gordonDrogon I was advised to do so as I am going to attempt to setup a cryptocurrency wallet.. and swapsize of 100 caused issues
[18:35] * Anodyne (~pi@unaffiliated/anodyne) Quit (Ping timeout: 276 seconds)
[18:35] <gordonDrogon> there's definately a latch mechnism on mine. I can see the little arm moving.
[18:36] <gordonDrogon> MiningInc, well if you've got the SD card space... however its going to run as slow as molasses if/when it swaps that much ...
[18:36] <ali1234> if you pull out the card then the next time you push it in, the latch disengages
[18:36] <MiningInc> NOTE*** there is a little ()hack() for fixing the broken SD slot arm, on pi.
[18:36] <ali1234> and that means it is really easy to pull out
[18:36] <GreeningGalaxy> I can see a little arm moving too, but it's sure not grabbing anything, just clicking the spring
[18:36] * LAN_Lord (~Thunderbi@2602:306:308b:5500:54c1:76ec:b322:f929) Quit (Ping timeout: 240 seconds)
[18:36] <t3chguy> oh so now the latch is in the wrong state ?
[18:37] <MiningInc> t3chguy I believe that is the issue...
[18:37] <MiningInc> not to steal anyones thunder.... ;-)
[18:37] <ali1234> t3chguy: on mine anyway
[18:37] <Valduare> just remembered, on ONE of my hard drives somewhere is a bitcoin wallet with 1.3 bitcoins ...
[18:37] <GreeningGalaxy> I'm perplexed by this because I've played with a lot of different SD/microSD slots and not once have I seen one that holds the card in when clicked in
[18:37] <MiningInc> ali1234 this happened with my first pi, day one
[18:38] <MiningInc> Valduare better go find that wallet.dat and put it in cold storage ;-)...
[18:38] <Valduare> lol
[18:38] <MiningInc> I'm trying to setup a Vanilla coin wallet, on my pi.
[18:38] <Valduare> could buy a lot of pi zero’s with that bitcoin heh
[18:38] * Efynox (Efynox@2a01:e35:2f42:a10:949b:292f:4cb1:849e) has joined #raspberrypi
[18:39] <MiningInc> hence the question on swapsize.. I am just not wanting to get midway into download/install and run out of swap/memory/etc.
[18:39] <ali1234> so basically if you pull the card out without pushing it takes extra force, and the next time you push the card in, the latch will immediately try to push it out again instead of locking
[18:39] <MiningInc> Valduare....right. You only need to find the pi zeros to buy.. lol
[18:39] <Valduare> I have one
[18:39] <Valduare> just not sure waht to use it for heh
[18:39] * tombrough (~tom@cpc3-newt3-0-0-cust8.19-3.cable.virginm.net) has joined #raspberrypi
[18:39] <MiningInc> Valduare I am a jealous little man
[18:39] <GreeningGalaxy> I have not encountered that, mine clicks in and out just fine, it just doesn't hold onto the card in any mechanical way
[18:40] <ThePendulum> was the Pi Zero even more powerful than the Pi 2, or is the Pi 2 still the one to grab in terms of performance?
[18:40] <GreeningGalaxy> other than friction that is
[18:40] <Valduare> pi2 is the best
[18:40] <MiningInc> Though....I still am tinkering around with what purpose my pi2 should be serving..lol
[18:40] <ThePendulum> alright
[18:40] <Valduare> pizero is second best
[18:40] <ali1234> on a non-broken socket in the correct state, pushing to eject takes more force than simply pulling the card out
[18:40] <GreeningGalaxy> ThePendulum� the pi zero outclasses the original B, but not the 2
[18:40] <ThePendulum> alright, I'll grab a Pi 2 then
[18:40] <ThePendulum> I now have an original Pi B
[18:40] <MiningInc> GreeningGalaxy +1
[18:40] * duckpuppy (~patrickai@ has joined #raspberrypi
[18:40] <ThePendulum> quite an investment though, need to get a new case and everything :
[18:40] <MiningInc> pi 2 is surprisingly zippy ;-) loving it.
[18:41] <ThePendulum> hehe
[18:41] <ThePendulum> yeah I imagine a HTPC would run fairly well on it given the original B was 'ok' already
[18:41] <ThePendulum> time to shove some food in my face
[18:41] <MiningInc> ThePendulum... May I recommend a canakit. That is IF you need wifi dongle, microSD card, case HDMI cord, etc... best value
[18:41] <MiningInc> ThePendulum indeed
[18:41] <Valduare> the pi0 runs kodi flawlessly

[18:43] <Valduare> bored of raspbian? :P
[18:43] <GreeningGalaxy> I have heard good things about RISC OS in the playing-around department
[18:43] <Valduare> just install a diff window manager
[18:43] <MiningInc> Any suggestions are appreciated... Thoughts on Kali? Kali + pi.?
[18:43] <MiningInc> Valduare +1
[18:43] <MiningInc> any suggestions?
[18:43] <GreeningGalaxy> isn't Kali just Debian with hacksy tools?
[18:43] <MiningInc> I have stuck to the command line primarily
[18:43] * Anitox_ (~Dan@unaffiliated/anitox) Quit (Ping timeout: 252 seconds)
[18:44] <MiningInc> GreeningGalaxy, IDK.. I am fairly fresh, far as getting back into linux. Guidance would be a plus.
[18:44] <gordonDrogon> GreeningGalaxy, RISC OS has been about for a very long time - it has a small but enthusiastic following. I've not used it for ~20 years.
[18:44] * Efynox (Efynox@2a01:e35:2f42:a10:949b:292f:4cb1:849e) Quit (Quit: Leaving)
[18:44] <GreeningGalaxy> If you're still calling yourself new, I'd recommend sticking with raspbian
[18:44] <GreeningGalaxy> it has a lot to offer

[18:45] <MiningInc> gordonDrogon GreeningGalaxy thanks for the RISC OS mention. Putting it on the list of "fun to do'
[18:45] <MiningInc> GreeningGalaxy Yeah.. Being an eager beaver....and this beaver still has only installed a single tool...
[18:45] * duckpuppy (~patrickai@ Quit (Ping timeout: 245 seconds)
[18:45] <GreeningGalaxy> I've been wanting to get a Plan 9 install running too, just as another 'for funsies' thing
[18:46] <GreeningGalaxy> of course, I'll probably never get anything besides raspbian to support my pitft, but that's probably ok
[18:46] * jmbarbier (~jmbarbier@rominet.solidev.net) Quit (Quit: My Mac has gone to sleep. ZZZzzz…)
[18:46] <MiningInc> so maybe jumping the gun a bit.... I am trying to re-familiarize self with command line basics, I.E. BASH/shell refresher + Terminal warmup.
[18:47] <GreeningGalaxy> raspbian's probably your go-to then, unless you want to throw yourself headlong into it and go with ALARM or something :P
[18:47] <MiningInc> was just looking @ pitft... I have no fun stuff YET for physical computing. So for now keep on diggin on the software side. which is plentiful. Problem is knowing where to start...! What to do, what to do.
[18:49] <MiningInc> Thanks for the input... Needed a bit of a reality check.. NOT rainman. sooo going to go try and find something fun to download and play with..
[18:49] <MiningInc> Suggestions on goodies for Raspbian?
[18:50] <GreeningGalaxy> if you're using a screen, i3 window manager is nice. very minimal, very out of the way
[18:50] <MiningInc> Keep in mind. I am also learning python(3) at moment. Still pretty green with that as well BUT am working towards a trade bot.. Probably start with a twitter bot or something first.
[18:50] <MiningInc> Thanks GreeningGalaxy
[18:51] <MiningInc> the default window manager is X window manger, right?
[18:51] <GreeningGalaxy> no, X is one level lower than that
[18:51] * whitby (~whitby@ Quit (Quit: https://i.imgur.com/JNE82x2.gifv)
[18:51] <GreeningGalaxy> a window manager is just what decides how applications in x appear
[18:51] <MiningInc> Ok. Thanks. Makes sense.
[18:52] <GreeningGalaxy> X is the display server which lets applications appear in the first place
[18:52] <MiningInc> gotcha, so without X...basically won't be able to display/see anything
[18:52] <GreeningGalaxy> well, you'll have a command line.
[18:52] <Valduare> openbox is the window manager for raspbian
[18:52] <gordonDrogon> well.. text consoles.
[18:52] <Valduare> openbox is real nice
[18:52] <GreeningGalaxy> whatever you can do before startx
[18:52] <tohipfortheroom> love openbox
[18:53] <Valduare> openbox is all I used in my archlinux days
[18:53] <gordonDrogon> you can do graphics in the consoles without invoking X.
[18:53] <GreeningGalaxy> window managers come in two main varieties, stacking and tiling. stacking ones are like Windows or Mac, they involve windows you can drag around and are the most common. Tiling window managers divide up the screen and don't let windows overlap.
[18:53] <MiningInc> thanks, openbox is it! I have done fairly extensive 'reading/tutorial-ing' on debian/raspbian beginner "what to do/ what to know"
[18:54] <gordonDrogon> openbox? not lxde then?
[18:54] <MiningInc> Now am just sitting with a blinking cursor waiting for commands

[18:55] <MiningInc> right, quick question on that... If I have setup to launch to CLI, not GUI..and launch GUI via startx, does this create multiple 'instances/processes' overlapping?
[18:56] <GreeningGalaxy> no, the CLI is essentially always there underneath x
[18:56] <MiningInc> Ok Thanks.
[18:56] <GreeningGalaxy> if you quit X, you'll drop back to it.
[18:56] <gordonDrogon> you can open a temrinal under the GUI, or switch back to text temporarilly with Shift+Alt+F2 ...
[18:56] <MiningInc> GreeningGalaxy Ok. So, How would I 'quit' X from command line
[18:57] <GreeningGalaxy> `sudo pkill -15 X`
[18:57] <MiningInc> ahh. Gotcha.
[18:57] <h4x3> hey guys
[18:57] <gordonDrogon> ah, just got openbox - I don't use lxde, so never realised how it integrated.

[18:57] <h4x3> is it possible
[18:57] <h4x3> ?
[18:57] <GreeningGalaxy> or yeah, switch tty with control-alt-fkeys
[18:57] <gordonDrogon> h4x3, http://eltechs.com/run-teamviewer-on-raspberry-pi/
[18:58] <MiningInc> so, are the terminals I can access via F2-F6 something that if switched to, then say closed it/exit/quit...would it crash the PI?
[18:58] <h4x3> heard from that
[18:58] <h4x3> but it costs money
[18:58] <h4x3> exagear
[18:58] <MiningInc> and IF I were to ever say 'lockup/freeze' pi . What would a poweroff w/o prompt do?
[18:58] <gordonDrogon> h4x3, sothe answer to your question is: Yes, it's possible.
[18:58] <GreeningGalaxy> no, if you exit the tty terminal, you just get a login prompt
[18:58] <gordonDrogon> MiningInc, you unplug the power - it's turned off.
[18:58] <GreeningGalaxy> or, if you have automatic login, you just get logged back in
[18:59] <MiningInc> ok GreeningGalaxy
[18:59] <gordonDrogon> MiningInc, Linux likes to be shut down nicely but most of the time you'll get away with pulling the plug. most of the time.
[18:59] <MiningInc> right. gordonDrogon does power failure/loss, unexpected that is.. Damaging to the pi or card
[18:59] <h4x3> ok again: is it possible to install teamviewer on my ubuntu mate pi2b cost-free?
[18:59] <MiningInc> gordonDrogon ok. That was my question. Thanks for suming it up
[18:59] <GreeningGalaxy> generally only so if you're in the middle of a write when it happens.
[19:00] <GreeningGalaxy> which it can be hard to tell, so it's good not to.
[19:00] <MiningInc> right.
[19:00] <MiningInc> Oh. and VIM
[19:00] <GreeningGalaxy> ext4 journaling will probably save you in most instances, but it only takes one failure to kill a card.
[19:00] <gordonDrogon> the foundation setup a Pi doing "work" with another Pi pulling the plug (power via a relay) I think they ran it randomly pulling the plug for some time (days/weeks) without any real issues...
[19:00] <GreeningGalaxy> or rather, kill an install, usually you can reflash fine
[19:00] <MiningInc> anyone please point me in a direction to some documents that are easy to understand
[19:00] <gordonDrogon> MiningInc, google for debian sys admin guide
[19:01] <MiningInc> the man -k VIM is like reading encyclopedia and not helpful.. to me anyway
[19:01] <gordonDrogon> MiningInc, basically almost all the debian docs will apply to Pi with raspbian.
[19:01] <MiningInc> gordonDrogon... you sir/man, are a keyword stacking boss ;-) thanks

[19:02] <MiningInc> gordonDrogon me too!
[19:02] <MiningInc> bakers ftw!
[19:02] <MiningInc> 4 cakes... godspeed

[19:04] * MiningInc is off to play with some of the new found knowledge now possessed, thanks to gordonDrogon, GreeningGalaxy, and Valduare.
[19:04] <GreeningGalaxy> MiningInc� vim is a text editor with a very steep learning curve. You can probably find guides online, but you also might want to use nano or something else in the meantime.
[19:04] <Valduare> np
[19:06] <MiningInc> VIM scared me... was my first 'Rut row!' few nights ago I somehow opened/entered VIM somehow accidentally, while playing on command line... DId not realize VIM was where/what I was in/doing... Had the pi freeze/calculating for hours and couldn't get back to the prompt.

[19:47] <exonormal> what does it do?
[19:47] <aem> nothing
[19:47] <exonormal> will it boot?

[19:48] <exonormal> or a laptop?
[19:48] <jrcharney> After much though and realizing how setting up my RetroPie with a Raspberry Pi 2 made so much more sense (especially with some of the power requirements some of the games and apps had), I kinda gae up on using a Pi Zero.
[19:48] * Tach[Away] is now known as Tachyon`

[19:49] <aem> exonormal if you're saying do a micro usb to usb and plug to pc

[19:49] <aem> then im about to try that
[19:49] <aem> monday
[19:49] <aem> but i still think usb is defective
[19:49] <exonormal> ok, plug the usb in pi zero and into the pc
[19:49] <jrcharney> Now if only the Pi foundation could find a good manufacturer for audio jacks
[19:49] <aem> yea i gotta get the cable first
[19:50] <exonormal> oh?
[19:50] <jrcharney> I would have gladly paid another $10 if the 7 inch touch display had audio speakers on it.
[19:50] <exonormal> how are you powering the pi zero?
[19:51] <aem> nvm found one
[19:51] <aem> exonormal using psu from rpi2

[19:55] <exonormal> try a different mini usb cable

[19:57] <aem> mgorbach i used noobs latest one
[19:57] <aem> i just used rpi 2 to install it
[19:58] <aem> and yes i see os even when i boot
[19:58] <aem> just no usb response
[19:58] <exonormal> try different cable
[19:58] <mgottschlag> do you see any usb-related lines on the screen?
[19:59] <aem> noep
[19:59] <aem> also exonormal sadly i dont have one
[19:59] <aem> a female usb to microusb
[19:59] <exonormal> in terminal key in lsusb
[19:59] <mgottschlag> because if it boots, then the core system is working, and if the USB port works in the bootloader, then that part of the hardware works as well
[19:59] <aem> exonormal i cant do that without a keyboard...
[20:00] <exonormal> do it on the PC...
[20:00] <mgottschlag> you might be able to do that in the rc.local script
[20:00] <mgottschlag> I don't know whether the output of that goes to the boot terminal though
[20:01] <aem> boot the rpi on pc?
[20:01] <exonormal> yes
[20:01] <aem> how lol
[20:02] <exonormal> plug the usb cable from pi to PC
[20:02] <exonormal> then see if PC sees it

[20:13] <exonormal> that way the keyboard and mouse will get enough power to function properly....
[20:14] <ozzzy> kbds and mice draw very little current
[20:14] <mgottschlag> exonormal: nonsense, the average USB mouse or keyboard will not draw anywhere near 100mA
[20:14] <aem> exonormal its not powered but i have wireless keyboard mice combo so it shouldbe be issue
[20:14] <mgottschlag> unless they are wireless, in which case a powered USB hub might actually be good
[20:14] <ozzzy> I plug a wireless kbd/mouse dongle into my phone all the time
[20:14] <mgottschlag> aem: eh... that's exactly the case where you might need more power
[20:15] <aem> mgottschlag why for wireless?
[20:15] <mgottschlag> because radio communication *is* energy intensive
[20:15] <mgottschlag> it depends on the brand, some draw more current than others
[20:15] <mgottschlag> but some use quite a lot of power
[20:15] <mgottschlag> still, if you use a strong power supply, you should be good
[20:15] <mgottschlag> because the pi zero has nothing sitting between power input and USB power output
[20:16] <mgottschlag> the pi zero doesn't need an USB hub as much as the regular pi
[20:16] <mgottschlag> *a powered USB hub
[20:16] <aem> mgottschlag i use the same as rpi 2
[20:16] <mgottschlag> yes, should be enough
[20:16] <aem> i have 2.5 amps
[20:16] <aem> yea
[20:16] <aem> so no need unless i want 5 hdds hooked up :)
[20:17] <mgottschlag> heh, it's not like USB HDDs care about the USB standard... many will happily draw much more than 500mA :)
[20:18] <mgottschlag> the only problem with the wireless mouse is that you might not be able to test the cable with a smartphone, because the smartphone might not provide enough current :)

[20:48] <Valduare> hmm
[20:48] <Valduare> so I have some rgb led strip 12v
[20:48] <Valduare> and a pi zero
[20:48] <Valduare> looks like I need 3 mosfets and some various components to get this up and running
[20:49] <mgottschlag> there are lots of those micro USB flash sticks, obviously only one of the connectors is usable at a time
[20:49] <Valduare> can I salvage those from an old atx power supply?
[20:49] <mgottschlag> Valduare: maybe
[20:49] <mgottschlag> the power supply will probably have MOSFETs, but maybe no suitable ones
[20:50] <mgottschlag> and you probably also need 3 npn transistors
[20:50] <mgottschlag> if the MOSFETs are not usable with 3.3V gate voltage
[20:50] <mgottschlag> oh, and the required type of MOSFETs depends on how your LEDs are connected
[20:50] <Valduare> what is the diff between a mosfet and transistor?
[20:51] * vade (~vade@pool-108-6-208-136.nycmny.fios.verizon.net) Quit (Quit: vade)
[20:51] <mgottschlag> wel, a mosfet (NMOS/PMOS) just is a different type of transistor compared to a bipolar transistor (NPN/PNP)
[20:51] <mgottschlag> the gate is isolated, and the gate charge "flips" the doped silicon across the gate isolator
[20:52] <Valduare> mosfets can run more current or somthing through them than a transistor?
[20:52] <mgottschlag> the voltage across a bipolar transistor is much higher, so MOSFETs will waste a lot less power
[20:53] <mgottschlag> and the dissipated heat is what usually limits the maximum current
[20:53] * Hix (~hix@97e0a009.skybroadband.com) has joined #raspberrypi

[21:03] <mgottschlag> yes
[21:03] <ThePendulum> what are mosfets used for with LED strips? similar to level shifters?
[21:04] <ThePendulum> are level shitters just a bunch of mosfets in an ic?
[21:04] <Valduare> my led strip is 12v
[21:04] <mgottschlag> ThePendulum: well, yeah... the pi can't provide 12V, and it cannot provide the required currents either
[21:04] <mgottschlag> ThePendulum: yes, indeed
[21:04] <ThePendulum> alright, yeah just curious about the difference
[21:04] <mgottschlag> just slightly smaller mosfets than what's required for LEDs :)
[21:04] <ThePendulum> I'm using a level shifter for the data channel of mine
[21:05] <ThePendulum> slightly smaller?
[21:05] <ThePendulum> oh right, if you're looking to go from 3.3V to 12V
[21:05] <mgottschlag> well, if you want to switch the *power* of the LED... so, if you don't have any "intelligent" LED
[21:05] <mgottschlag> the current capacity scales with the physical size of the transistor, and the MOSFETs embedded on the usual level shifter are designed to conduct ~20mA or something in that ballpark

[21:08] <mgottschlag> usually, you cannot just wire speakers directly to GPIO
[21:08] <mgottschlag> unless they have an amplifier already built in
[21:08] <jrcharney> 8 ohm 0.5 watt
[21:08] <mgottschlag> yeah, you'll need an amplifier for that
[21:09] <mgottschlag> and the pi's GPIO can only output I2S audio iirc, that's digital

[21:28] <Luyin> hi guys, I've put this in the /etc/network/interfaces of our rpi: https://bpaste.net/show/1ec22c62d1bd , but now I saw that the router has given it the IP 0.20. so what did I do wrong, or is there something else I have to change?
[21:29] <PhotoJim> you probably forgot to stop the dhcp client
[21:30] <Luyin> PhotoJim: on the rpi?
[21:30] <PhotoJim> yes
[21:30] <PhotoJim> the dhcp server runs on your router (or whatever device provides IP)
[21:30] <PhotoJim> the dhcp client asks for addresses on the client machine
[21:30] <PhotoJim> you might also want to put a gateway line in that config file
[21:31] <PhotoJim> assuming you want to talk to the world outside your LAN
[21:31] <PhotoJim> oh never mind, you did
