[0:43] <giddles> 16,99eur cost a rpi zero for me :( that are around 12,30 British Pound or 18,47$
[0:44] <Reedy> 12.30 gbp is 16.87
[0:44] <Reedy> barely any cheaper
[0:44] * TyrfingMjolnir (~Tyrfing@ has joined #raspberrypi
[0:44] <Reedy> Oh, you already converted
[0:44] <Reedy> Ignore me, being stupid
[0:44] <giddles> of cause
[0:44] <giddles> np
[0:46] <giddles> in usa and uk they cost around 5$?
[0:46] <giddles> or 3Pound
[0:47] * zesterer (~zesterer@ has joined #raspberrypi
[0:47] <Reedy> looks like 4 GBP
[0:47] <Stanto> treeherder: the problem with the apps you mention is they dont use the videocore iirc so its dependent on the slow cpu in the model b
[0:49] <giddles> ok 4gbp
[0:49] <Reedy> 5usd is 3.35 gbp
[0:50] <Reedy> I wonder how it's cheaper to make them in the uk, and ship them to the states to sell them for cheaper than it is in the UK...
[0:50] <Reedy> even if you put us tax ontop
[0:50] <Stanto> if you notice a lot of companies outside of the uk sold it in a bundle

[1:35] <irc_smirk> question
[1:36] <irc_smirk> im trying to back up my sd card from raspberry pi back to an img file
[1:36] <irc_smirk> i am on macosx and i typed
[1:36] <irc_smirk> dd if=sd.img of=/dev/disk2 bs=1m
[1:36] <irc_smirk> i get dd: sd.img: No such file or directory
[1:37] <irc_smirk> this is a 32 gig card. will it back up as a 32 gig file?
[1:37] <irc_smirk> i am hardly using 100 meg on the card right now

[1:51] <irc_smirk> ok lesson learnt. dont buy a 32 gig sd card to run rasp

[1:55] * turtlehat (~turtlehat@ Quit (Quit: gone)
[1:57] <BurtyB> irc_smirk, it looks like you have that command the wrong way around if you're trying to create a backup of an SD card
[1:57] <irc_smirk> you are right
[1:58] <irc_smirk> i unmounted the sdcard. how do i get it to show up again
[1:58] * KindOne is now known as nenolod
[1:58] * nenolod (kindone@colchester-lug/silly-fool/donut) Quit (Disconnected by services)
[1:58] * KindOne (kindone@colchester-lug/silly-fool/donut) has joined #raspberrypi
[1:59] <irc_smirk> ok this worked diskutil mountDisk /dev/disk2
[2:00] <irc_smirk> so im correct in my thikning. to back up this 32gig sd card it will produce a file that is 32gig?
[2:00] <irc_smirk> cant i just copy all the files to a folder?
[2:01] * Nightcinder|CLE is now known as Nightcinder
[2:01] <irc_smirk> i do a 'getinfo' on the volume and its only 60 megs
[2:01] <irc_smirk> thats all i want backedup
[2:03] * GentileBen (GentileBen@cpc70133-lutn12-2-0-cust324.9-3.cable.virginm.net) Quit ()
[2:05] <BurtyB> irc_smirk, I woulnd't advise having it mounted when you're copying it. I'd advise looking for a howto on how to backup the SD card from you OS
[2:05] <irc_smirk> yeah ive done that
[2:05] * wiiguy (~fake@unaffiliated/wiiguy) Quit (Read error: Connection reset by peer)
[2:05] <irc_smirk> what im getting at is the backup will basically clone the entire 32 gigs
[2:05] <irc_smirk> which i dont want
[2:05] <irc_smirk> so looks like im goign to have to start all over with a 4 gig sd card
[2:06] * weemsledeux (~textual@unaffiliated/weems) has joined #raspberrypi
[2:07] * aphirst (~aphirst@adsl-87-102-22-14.karoo.KCOM.COM) has joined #raspberrypi
[2:09] <irc_smirk> is that basically it?
[2:09] <irc_smirk> is ther e away to backup the pi wihtout cloning the entire sd card/
[2:11] <chesty> irc_smirk: you can mount then cp -a
[2:11] <chesty> but it will be more than 80M, more like 1G depending on distro
[2:12] <irc_smirk> i mean can it work simpy by copying files from one folder to another?
[2:12] <chesty> yup
[2:12] <irc_smirk> but what about partitiones etc
[2:13] <irc_smirk> like could i zip up my pi install and send it to you that way?
[2:13] <chesty> there are two partitions, back them both up
[2:13] <chesty> yes irc_smirk, the /boot is probably 80M thinking about it
[2:14] <chesty> the / is more like 1G
[2:15] <chesty> you're better off using tar cjf rpi.tbz /media/rpi than cp though
[2:15] <chesty> that's if you mount the second partition of your rpi on /media/rpi
[2:15] <irc_smirk> sorry i dont understand
[2:16] <irc_smirk> when i put my microsd card into my mac
[2:16] <irc_smirk> i get a NONAME volume
[2:16] <irc_smirk> and inside that files and a folder
[2:16] <chesty> that's probably /boot
[2:16] <irc_smirk> that is 80 megs
[2:16] <chesty> yes, that's /boot.
[2:16] <irc_smirk> so wher eis the mystery 1 gig
[2:17] <chesty> say the pi is /dev/disk2 i think you'll have /dev/disk2p1 and /dev/disk2p2
[2:17] <chesty> i'm not sure how the mac does it, but you'll have two partitions, the mac is mounting the first
[2:17] <irc_smirk> this is what i see with diskutil list
[2:17] <irc_smirk> http://i.imgur.com/eI5ynxE.png
[2:17] <chesty> is you run mount | grep disk2 you sould see the device the mac is using
[2:18] * bizarro_1 (~bizarro_1@22.Red-83-47-132.dynamicIP.rima-tde.net) Quit (Quit: Leaving)
[2:18] <Ispira> meow
[2:18] <Ispira> setting up my pi to stream games.
[2:18] <irc_smirk> pussy. i wish
[2:18] <chesty> oh, so mount /dev/disk2s2 /media/rpi
[2:18] <chesty> /media/rpi needs to exist
[2:20] <irc_smirk> for what reason
[2:22] <chesty> i mean you can mount the partition anyway on a empty directory. mkdir /Users/irc_smirk/rpi, then mount /dev/disk2s2 /Users/irc_smirk/rpi the name of the directory doesn't matter
[2:22] <chesty> it just has to exist
[2:23] <irc_smirk> to copy the othe rone?
[2:23] <chesty> after you mount it, that you can copy it
[2:23] <chesty> then
[2:24] <irc_smirk> ok, then 2 years from no wwhen i get anew sd card. how do i copy it back
[2:24] <warpie> what's command to change account name?
[2:25] <chesty> dd a new rpi to the card, then mount the second partition the same way, then copy bacl
[2:25] <chesty> back
[2:26] * bigx (~bigx@ANantes-555-1-281-63.w90-12.abo.wanadoo.fr) has joined #raspberrypi
[2:26] <irc_smirk> ok
[2:27] <irc_smirk> maybe 2 years from now ill know what the f*ck you are saying lol
[2:28] <irc_smirk> i suck but im learning what i suck at
[2:28] <chesty> how did you make the first sd card?
[2:28] <irc_smirk> with the usual tutorials on instlaling
[2:28] <irc_smirk> i mad emistake of starting with 32 gig
[2:29] <chesty> so you follow them again, then you mount /dev/disk2s2 and copy everything back
[2:29] <irc_smirk> the thing is relaly slow on write. even though its said to be very fast
[2:29] <irc_smirk> yeah i dont understand why that would help it
[2:29] <irc_smirk> who woudl it know that new mount is relaated
[2:30] <chesty> when you mount a sd card, you are reading and writing onto the sd card
[2:30] <irc_smirk> ok thanks im going to table this
[2:31] <irc_smirk> too burnt out
[2:31] <chesty> rodger, time for me to head out too. see ya
[2:31] <irc_smirk> thanks for your time

[4:16] <kd7jwc> snowkidind, thats a healthy sized breadboard
[4:16] <snowkidind> ive used it for other projects
[4:17] <snowkidind> i got a good price and one day bought like ten of them
[4:18] <Chillum> for $5 I would buy 10 too
[4:18] <snowkidind> it was a bit of a challenge to figure out that arduino shield thing but i like it
[4:18] <Chillum> always nice to have a box of extra computers
[4:18] <snowkidind> i was at micro center today the guy was talking about the black friday
[4:18] <snowkidind> they had 250 of them
[4:18] <snowkidind> sold out in 2 hours
[4:18] <snowkidind> and they had a limit of 2 percustomer,
[4:19] <snowkidind> if they wanted more than one the price was ten each
[4:22] <Ispira> neat.
[4:22] <Ispira> my drawing tablet's usb cable can power my Pi.
[4:22] <Ispira> i found that out by accident when i plugged the wrong cable in.

[4:25] <r_02> Can you guys suggest a kit for someone that hasn't had any experience with that?
[4:25] <Ispira> an rpi kit?
[4:26] <r_02> I have some rpi's
[4:26] <Ispira> ah what are you looking for specifically then?
[4:26] <r_02> I mean that bread board
[4:26] <Ispira> Ah! uno momento
[4:26] <Ispira> How much are you wanting to spend on it
[4:26] <Ispira> because there are tons of kits of varying size/price/complexity when it comes to that.
[4:27] <Ispira> you're usually governed by the amount of money you want to spend to get started.

[4:27] <r_02> Well as for complexity, I know very little on it
[4:28] <r_02> About wiring that sort of stuff.
[4:28] <Ispira> i have a link for you
[4:28] <Ispira> http://www.amazon.com/s/ref=nb_sb_noss_2?url=search-alias%3Daps&field-keywords=breadboard+kit
[4:29] <Ispira> pretty much anything that'll work with an arduino will work with the pi.
[4:29] <Ispira> the only thing you might have an issue with is very specifically designed LCD panels, but I can imagine they'd work with the pi too.

[4:29] <shiftplusone> http://thepihut.com/collections/camjam-edukit
[4:30] <snowkidind> ebay is cheap
[4:30] <Ispira> that edukit is nice for something real cheap
[4:30] <shiftplusone> Those are fairly educational
[4:31] <shiftplusone> There are a lot of 'kits' which are just keyboard and mouse plus useless stuff. "Build a computer" type nonsense. edukit is actual components you can make stuff out of.
[4:31] <snowkidind> depends on what you are getting in to
[4:31] <Ispira> ^
[4:31] <snowkidind> i bought a ton of stuff
[4:31] <snowkidind> but i was studying electronics at the time
[4:32] <snowkidind> and i ended up getting resistor kits
[4:32] <Ispira> OH. looking on amazon at these I found one that <I> want
[4:32] <snowkidind> and just about everything
[4:32] <snowkidind> but i bought it all seperately and i have much more of the things that one would normally get in a kit
[4:32] * cpe (~cpe@unaffiliated/cpe) Quit (Ping timeout: 246 seconds)
[4:32] <shiftplusone> snowkidind: yeah, but if you're just getting started you might not know the value of a resistor kit and all those other things, so it's nice to get an assortment of things to get started
[4:32] <snowkidind> and those little jumper wires that come in a sectional plastic box are invaluable
[4:32] <Ispira> I wish there was like
[4:33] <Ispira> a store where you could just walk in and pick these little things up easily
[4:33] <snowkidind> microcenter
[4:33] <Ispira> resistors, caps, breadboard/wire/etc
[4:33] <shiftplusone> then notice "hey.... these resistor things are handy, I should get a lot of different values of these...." then the next thing you know, you have a tub full of useful components at hand.
[4:33] <snowkidind> had a pretty nice display of that stuff
[4:33] <Ispira> closest micrcenter is like... 4 hours drive from me
[4:33] <Ispira> I live in south alabama rofl
[4:34] * cpe (~cpe@unaffiliated/cpe) has joined #raspberrypi
[4:34] <Ispira> my thing has been recycling old toys for wires/etc
[4:34] <Ispira> But it seems my soldering iron has dissappeared.
[4:34] <Ispira> disappeared *
[4:34] <snowkidind> they have an adapter that connects a cable to the pi but I just jump straight off it to the breadboard
[4:34] <Ispira> and without a soldering iron... well I'm kinda screwed
[4:34] <shiftplusone> Heh.... I used to desolder caps and chips from broken electronics and stuff >.> Not really necessary nowadays.

[4:35] <Ispira> shiftplusone: that's what I wanna be doing, because free stuff
[4:35] <Ispira> I have TONS of old stuff like that to get resistors, caps, etc from but no iro anymore
[4:35] <snowkidind> that link is just an example of the stuff on ebay
[4:36] <Ispira> i got a couple of DC motors from an rc car
[4:36] <snowkidind> for like 5 bucks you can get a ton
[4:36] <Ispira> a wireless transmitter and reciever (49mhz)
[4:36] <Ispira> but no way to use them >:L
[4:36] <shiftplusone> Ooh.... side note.... you can use a variation of pifm to control cheap ebay RC cars
[4:37] <shiftplusone> my nephew had one and I was thinking..... surely, you can use a pi to control this.... googled it and sure enough.... someone has done it
[4:37] <Ispira> that's my plan
[4:37] <Ispira> only I was going to write the stuff myself

[4:38] <Ispira> my ultimate goal is to put a small camera on the front of the second car, set the remote up to be controlled by the raspberry pi taking input from an xbox controller
[4:38] <Ispira> and drive the car around using my pc
[4:38] <snowkidind> i saw a model train with that
[4:39] <Ispira> It's so useless, but so fun.
[4:39] <Ispira> it's my new hobby.
[4:39] <shiftplusone> heh
[4:39] <Ispira> making things needlessly complicated using small computers and chips like pi/arduino
[4:41] <Ispira> fuck sake
[4:41] <Ispira> just shocked myself :(

[4:43] <Chillum> anyone know where I can get a Pi Zero for under $20?
[4:43] <snowkidind> wait until you accidentally do it lol
[4:43] <snowkidind> jeses ill never forget that
[4:44] <snowkidind> it was dead silent and i couldnt figure it out so I was about two inches away and bam

[5:22] * Aboba (~Bob@S010614cc209fc3d3.gv.shawcable.net) Quit (Ping timeout: 246 seconds)
[5:22] <snowkidind> my friend invented some sort of passive surveillance by triangulating radio signals and canceling them out
[5:23] <Chillum> ya just a single telescoping antenna like a FM radio from the 80s might have
[5:23] <snowkidind> i wonder what you could do with one of those big ham towers
[5:23] <Chillum> you can get specific ants and filters and boosters for the 1090 freq
[5:23] <Chillum> you can only improve so much because it is mostly to do with the transmit power of the plane's transponder
[5:24] <Chillum> 400km is about as far as people can detect, and even then you need very high ground
[5:24] <snowkidind> right
[5:24] <Chillum> curvature of the Earth becomes and issue
[5:24] <snowkidind> sounds about right
[5:24] * swift110-phone (~swift110-@unaffiliated/swift110) Quit (Ping timeout: 240 seconds)
[5:24] <snowkidind> that and moisture
[5:24] <Chillum> the freq they use is very long range for low power but cannot get through solids very well so you need line of sight to the sky
[5:24] <Chillum> where I am I have hills and stuff so I only detect high altitude planes
[5:25] <snowkidind> I was considering the thought of an underwater array of autonomous vehicles
[5:25] * Flutterbat (~flutterba@unaffiliated/day) has joined #raspberrypi
[5:25] <snowkidind> like if (mh370) a plane went missing you could send out this array of vehicles to scan for the pinger
[5:25] <snowkidind> it could also terrain map the seafloor
[5:26] <snowkidind> too complicated for one person to make
[5:26] <snowkidind> so i just bagged the thought
[5:27] <snowkidind> the idea was that you could use sort of a bit torrent style network where all the vehicles knew about each oter and moved around in a way that they refuel and still search forward
[5:28] <Chillum> https://en.wikipedia.org/wiki/Underwater_glider <-- super power efficient

[5:29] <snowkidind> surely
[5:29] <snowkidind> i was thinking smaller scale at first for prototyping

[5:40] <Spitalian> okay, so everything I read said that when it first boots it will prompt me to put in the username and password, and then I type "startx" to launch the gui. But when I booted it, it didn't ask for a username or password and it just went straight to the desktop
[5:40] <Spitalian> I don't know why
[5:41] <snowkidind> that happened to me too
[5:41] <snowkidind> old instructions
[5:41] <snowkidind> you used noobs?

[5:42] <warpie> you can go into terminal and do sudo raspi-config and put in user and pw

There is also an option to change the password (in the gui) but when I change my password that way the new password doesn't work. Is it better to do that kind of stuff through the terminal?

[6:20] <irc_smirk> something may be wrong with my sd card
[6:21] <irc_smirk> it says 20meg/sec write
[6:21] <warpie> cud be
[6:21] <irc_smirk> how to diagnose
[6:21] <warpie> ask [Saint] or niston
[6:21] <snowkidind> takes a while to compile

[6:24] <sedition> docker imports and exports will take time

[6:26] <irc_smirk> yeah once docker is done importing its a huge advantage
[6:26] <irc_smirk> i found jasper for docker on pi here trying it out https://github.com/danielchalef/jasper-docker
[6:26] <warpie> isn't there something better than docker?
[6:27] <irc_smirk> i think ill probalby just mess with it on mac docker first
[6:27] <sedition> that looks like a cool project
[6:27] <sedition> warpie: dunno, docker seems to be the new hotness
[6:27] <warpie> ok
[6:27] <sedition> its useful for me in the few ways that i use it on a daily basis
[6:27] <sedition> i have no complaints
[6:27] <warpie> enjoy
[6:27] <irc_smirk> whats your use for it?
[6:28] <sedition> mostly keeping kali in a box for penetration testing engagements.
[6:28] <sedition> very useful to have all my tools inside a container native on my macbook
[6:28] <sedition> and easy to deploy to whatever machines i have to work with
[6:28] <snowkidind> night guys
[6:28] <sedition> see ya
[6:29] <sedition> im trying to learn more about it so i can start deploying my apps in docker etc
[6:29] <irc_smirk> but doesnt the arm part trip that up
[6:29] <irc_smirk> it seems you have to build up an image on both sides
[6:29] <sedition> yeah i have an image for am and an x86 image
[6:29] <sedition> arm*
[6:29] <irc_smirk> then you use volumes outside?
[6:29] <sedition> yep, and port forward as needed
[6:30] <irc_smirk> you cant mix image layers at all right?
[6:30] <sedition> ive been trying to mess with privileged mode or whatever to give docker access to my wireless cards but no luck so far
[6:30] <sedition> not sure what you mean by mix, but if you have lets say, the base ubuntu image, other images based on that image will only need to download the layers 'above' that layer you already have
[6:31] <sedition> again im not a docker expert so i may be incorrect in some of my understanding
[6:31] <irc_smirk> ok
[6:32] <sedition> i think there could wind up being a lot of folks publishing docker images for pi apps, lots of potential
[6:32] <pigrit> any realistic chance one could harvest old mobile phones for components to give the pi gsm/3g capabilities ?
[6:32] <irc_smirk> i was going to build an api site that let you upload large images (30 meg) but now im seeign pi on sd card will be too slow
[6:33] <irc_smirk> sedition - web based only right? i cant see it doing something like retro pi
[6:34] * spvensko (~spvensko@unaffiliated/spvensko) Quit (Quit: My Mac has gone to sleep. ZZZzzz…)
[6:36] <sedition> you could stuff whatever in there heh
[6:37] <sedition> Also what speed are your SD cards?
[6:37] <irc_smirk> its supposed to be the best one when i researched
[6:38] <sedition> you might get better speed from USB
[6:38] <sedition> check this out
[6:38] <irc_smirk> http://www.bestbuy.com/site/samsung-evo-32gb-microsdhc-class-10-uhs-1-memory-card-red-white/4568505.p?id=1219769553726&skuId=4568505
[6:38] <sedition> http://www.mikronauts.com/raspberry-pi/raspberry-pi-2-usb-hard-drive-and-adapter-tests/
[6:38] <sedition> "(FYI: in the Raspberry Pi 2 Review, the ADATA SD card scored 17.5MB/sec on this hdparm test)"
[6:39] <sedition> so just do your storage on a USB stick :)
[6:39] <sedition> for your app
[6:41] <irc_smirk> so my sd card says Maximum Write Speed20 megabytes per second
[6:41] <irc_smirk> but it doesnt do this at all

[6:45] <sedition> although it shows you some args you need to pass in the readme
[6:45] <sedition> for whatever devices you're using
[6:45] <irc_smirk> yeah that failed
[6:45] <irc_smirk> ok will read the readme lol
[6:46] <irc_smirk> just silently fails

[6:52] <Chillum> at only 23 grams the pizero is going to replace the Pi2 on my quadcopter
[6:52] <Chillum> weight matters
[6:52] <Chillum> less power too
[6:53] <irc_smirk> how much p2 weigh
[6:54] * netzfisch (~Thunderbi@x55b06038.dyn.telefonica.de) has joined #raspberrypi
[6:55] <Chillum> huh only 45 grams, somehow I thought more
[6:55] <Chillum> ohhh I misread, the Pi zero is only 9 grams
[6:55] <Chillum> that makes more sense
[6:56] <irc_smirk> what connects to it. just power?
[6:56] <Chillum> power and a wifi chip
[6:56] <Chillum> war flying
[6:56] * zesterer (~zesterer@ Quit (Quit: Leaving)
[6:56] <Chillum> but the big gain is the power consumption, 65mA vs ~420mA
[6:57] <irc_smirk> what is the range on the wifi ?
[6:57] <Chillum> the battery is the big weight, I can use much smaller battery for this one
[6:57] <Chillum> 50-60 meters, line of sight depending on the tx power
[6:57] <Chillum> when flying you pick up much farther than on the ground
[6:57] <irc_smirk> ah cool
[6:57] * j12t (~j12t@c-107-3-142-14.hsd1.ca.comcast.net) has joined #raspberrypi
[6:57] <irc_smirk> so it connects to your homebase controller or whatever?
[6:58] <Chillum> so it scans wifi and records it
[6:58] <irc_smirk> like on a local wifi netwrok
[6:58] * mgottschlag (~quassel@reactos/tester/phoenix64) has joined #raspberrypi
[6:58] <Chillum> it uses GPS to map wifi locations

[6:58] <Chillum> I have taken the casing off of a tiny usb wifi, it is under 2 grams. Going to desolder the microusb port and solder the chip right to the board
[6:59] <irc_smirk> but that cant be legal i mean to fly so low
[6:59] <Chillum> gps will come in through the serial port
[6:59] * snowkidind (~snowkidin@pool-96-255-209-107.washdc.fios.verizon.net) Quit (Quit: snowkidind)
[6:59] <Chillum> 60 meters is not that low, nothing over 3 stories in this area
[7:00] <irc_smirk> wait so its legal to fly drones low like that in a city
[7:00] <Chillum> I am outside the city
[7:00] <Chillum> not much established law yet
[7:00] <Chillum> it falls under the old rc plane laws which only require you retain line of sight
[7:00] <irc_smirk> ah
[7:01] * swift110-phone (~swift110-@unaffiliated/swift110) has joined #raspberrypi
[7:01] <Chillum> using a remote camera to fly when you can't see it is illegal here if you don';t own the property
[7:02] <Chillum> in Canada at least
[7:02] <[Saint]> most places are following a similar format and rushing to pass legislation as such
[7:02] <irc_smirk> and im sure that doesnt apply to mr polipoli
[7:02] <[Saint]> drones kinda caught the law by surprise.
[7:03] <Chillum> they will become so cheap that people will just break the law and let it get shot down hehe
[7:03] * XpineX (~XpineX@1503024526.dhcp.dbnet.dk) Quit (Remote host closed the connection)
[7:03] <Chillum> is a usb sound card the best bet for sound on a pizero?
[7:03] <Lartza> Here drones need to fly under 150 meters, within 500 meters from the operatoor and not over people or densly populated areas
[7:03] <irc_smirk> well they could trace it back to you
[7:03] <[Saint]> what used to be confined to private aerodromes, and fairly extreme hobbiests, is now available for $30 on ebay for every man woman and child.
[7:03] <[Saint]> with increasingly better quality.
[7:04] <[Saint]> current laws weren't really prepared for it, but in hindsight, it wasn't too hard to see it coming.
[7:04] <Chillum> irc_smirk: you could use a cheap 4g card with pay as you go sim card and control it through tor... really depends on what you want to do
[7:05] <Chillum> they are not going to put much effort into tracing someone illegally hobby flying, but if you used to for a prison break then perhaps another story
[7:05] <Chillum> I think I read about a prison shooting down a quadcopter flying over their walls, it had a cellphone and some drugs on it
[7:05] <irc_smirk> haha a modern pigeon

[8:31] <AiGreek> almost here :D
[8:31] <AiGreek> today or tomorrow i think
[8:31] <Lonefish> woohoow!
[8:31] <nemesit|znc> hi, I got a pi but no screen, keyboard or mouse ;-p but I got lots of cables, anyway to install an os on the pi and connect to uart without those 3 things?
[8:32] * j12t (~j12t@c-107-3-142-14.hsd1.ca.comcast.net) Quit (Ping timeout: 260 seconds)
[8:32] <AiGreek> I called directly Kubii to yell, after our little discussion. In 2 hours, the shipping status was updated ^^
[8:33] <Lonefish> Haha, yelling is fun
[8:33] <Lonefish> I'm glad it worked
[8:33] <AiGreek> me too ... after more than a month, it was time
[8:33] <Lonefish> nemesit|znc: you should be able to copy the os over to an sd card, and then install it over ssh,
[8:34] <Lonefish> but I don't know how that would work tbh
[8:34] <AiGreek> just connect with your IP adress
[8:34] <Lonefish> https://www.raspberrypi.org/forums/viewtopic.php?f=28&t=83133
[8:34] <nemesit|znc> Lonefish: I might have only uart and other small cables no ethernet either xD
[8:34] <Lonefish> Put raspbian directly on it, not the NOOBS version
[8:35] <nemesit|znc> I'd like arch not raspbian
[8:35] <nemesit|znc> might complicate it a bit more xD
[8:35] <AiGreek> it's become dificult, here ^^'
[8:35] <Lonefish> I'm afraid you don't really have much options :p
[8:35] <nemesit|znc> could I put raspbian on it and afterwards arch from within raspbian?
[8:36] <Lonefish> Might be possible
[8:36] <Lonefish> google says this "Note that if you have installed any Linux OS on your Raspberry Pi, you can use that to create the SD card with Arch Linux on it, following the instructions provided earlier in this thread. You certainly can download the files needed for your Pi with your Windows machine, but the final creation of the OS for your Pi will need to take place on a Linux system."
[8:36] <AiGreek> https://www.raspberrypi.org/downloads/ uh ? Arch wasn't here ?
[8:36] <Lonefish> Don't think arch is officially supported?

[8:39] <Lonefish> don't you need to install drivers for uart? (not sure)
[8:39] <nemesit|znc> so as soon as some os is running with serial support It should work
[8:39] <AiGreek> can't you just buy an eth cable ? ^^
[8:39] <Lonefish> or enable it?
[8:39] <Lonefish> Or unplug something? :p
[8:39] <nemesit|znc> AiGreek: I don't have an ethernet port xD

[8:40] <nemesit|znc> no
[8:40] <nemesit|znc> lte modem xD

[8:54] <AiGreek> only one way to know i guess .... i'll try
[8:55] <pigrit> I was thinking maybe i/r ? lasers ?
[8:55] <pigrit> echolocation ?
[8:56] * cstk421 (~cstk421@99-20-229-203.lightspeed.brhmmi.sbcglobal.net) Quit ()
[8:56] <AiGreek> lasers are cool !
[8:56] * Kozuch (~Kozuch@78-80-181-179.tmcz.cz) has joined #raspberrypi
[8:56] <Lonefish> ir is short range I think
[8:56] <Lonefish> 30-50cm i thought
[8:57] <pigrit> bit too small of a room
[8:57] <Lonefish> or that might be echolocation
[8:57] <AiGreek> there is a sensors with 300m range
[8:57] <pigrit> tv remotes go farther than that
[8:57] <pigrit> what do builders use ? I've seen them use a handheld device to check how far something is
[8:58] <Lonefish> I think it's laser
[8:58] <Lonefish> I thought they send out a red dot
[8:58] <AiGreek> you can use Ultrasonic Sensors (for pi)
[8:58] <pigrit> it would be ideal that you put the pi down in the room, it does its thing, and comes up with a profile of the walls/obstacles
[8:59] <Lonefish> You want multiple measurements?
[8:59] <pigrit> depends on what you mean with multiple I guess ?
[8:59] <Lonefish> I thought you wanted to put it in the corner and measure one wall, go to the next, measure that wall..
[8:59] * j12t (~j12t@c-107-3-142-14.hsd1.ca.comcast.net) has joined #raspberrypi

[9:00] <pigrit> the COOL way, would be for it to scan 360°
[9:00] <AiGreek> pigrit use this http://www.leboutte.be/images/catalogue/outillage/stanley-metre-fat-max.jpg
[9:00] * jektrix (~jektrix@202-161-78-80.tpgi.com.au) Quit (Quit: Textual IRC Client: www.textualapp.com)
[9:00] <pigrit> lolol
[9:00] <Lonefish> I think you'll need to go with lasers and camera's for that :p You can use 3d scanning techniques, but I don't know if you could pull measurements from that
[9:01] <pigrit> I suppose you could make a small robot that drags the end
[9:01] <Lonefish> Maybe if you put a 1m stick in the scanning field you could calculate it
[9:03] <Lonefish> it would be a pain to code tho
[9:04] <pigrit> without knowing anything about it, I thought I could just make the basic wall to wall measurer, and then turn it around on top of a motorthingi
[9:04] <pigrit> write down all the data as it turns ofc
[9:05] <Lonefish> that might work indeed
[9:05] <AiGreek> maybe i don't understand what you want to do, but i thought it was easy to do :x
[9:05] * Guest94881 (kangarang@unaffiliated/cr5315) has joined #raspberrypi
[9:05] <Lonefish> but i think you'd have to pause it tho, and not spin it around continuously
[9:06] <Lonefish> like turn, pause, measure, pause, turn x degrees, repeat
[9:06] <pigrit> could be, could be
[9:06] <Lonefish> I'm also not an expert at all, just thinking out loud
[9:06] <pigrit> AiGreek I want to measure a room by pressing a button
[9:07] <Lonefish> he wants to work 20 hours on coding something to do something he could probably do in 2 hours by hand.
[9:07] <pigrit> yup
[9:07] <Lonefish> http://www.modmypi.com/blog/hc-sr04-ultrasonic-range-sensor-on-the-raspberry-pi
[9:07] <pigrit> and which probably already exists
[9:08] <Lonefish> ultrasonic is the one i was talking about earlier, changed it up with ir
[9:08] <pigrit> like, I could mention it to a builder and he'd say "oh yes of course, the Thingimabob, it's 5€ in the chinese shop"

[9:08] <Lonefish> "Provides precise, non-contact distance measurements within a 2 cm to 3 m range."
[9:09] <Lonefish> If your room is max 6m diameter, ultrasonic might work
[9:09] <Armand> lazor
[9:09] <AiGreek> Lonefish that what i said "with ultrasonic sensor (for pi) :(
[9:10] <Lonefish> https://www.adafruit.com/products/1568
[9:10] <Lonefish> this one goes to 5m
[9:10] <AiGreek> brb
[9:11] <Lonefish> apparently the usable distance is pretty specific for every implementation
[9:11] <Lonefish> I thought ultrasonic was more near-field
[9:12] <Lonefish> You could use a bat and tape it to your pi?

[9:37] <Apocx> since arduino longs are 32-bit. yeah that should work

[14:16] <styler2go> how can i sync the clock of the pi withpout having itnernet access? :/
[14:17] <canton7> what would you sync it with?
[14:17] <shinji257> You need to add a RTC module to the Pi. They add a crystal with battery backup capabilities and usually mount onto the header.
[14:20] <shinji257> Alternatively if you just need local network without internet you could setup/use a local NTP server. Actually doing so is beyond the scope of the room though.

[14:27] <mlelstv> http://rdlazaro.info/compu-Raspberry_Pi-RPi-stratum0.html
[14:28] <shinji257> I don't think you will be able to do that from within a running OS on the RasPi unless you are doing it to a different SD card.
[14:28] <Langley> So no matter what I have to shut it down and take the SD card out, right? Oh well
[14:28] <shinji257> Pretty much.
[14:30] <shinji257> It is like a computer still. If you have one computer and want to install a different OS you can burn the install ISO to a DVD or write it a USB drive but you still won't be able to just overwrite the current OS installation while inside the running system. You would also still have to reboot in order to start said install.

[16:02] <chesty> ah, raspivid is in fullscreen mode

[16:19] * rwb1 (~Thunderbi@host55.vsac.cust.sover.net) has joined #raspberrypi
[16:19] <gordonDrogon> but short circuit to 3.3v or 0v ... you configure the pin as an output.

[16:19] <gordonDrogon> indeed.
[16:19] <gordonDrogon> and remove the internal pull-up/down resistor
[16:20] <mgottschlag> knobo: that doesn't always work though, it only works if your external circuitry is <3.3V
[16:20] <mgottschlag> if it isn't (one example would be if you try to switch a computer on by shorting the power switch), you need another transistor

[17:07] * taza (~taza@unaffiliated/taza) has joined #raspberrypi
[17:07] <Apocx> since 1.5Kb/s is not exactly fast
[17:08] <Chillum> hmmm, I could. I would have to do a lot more research first
[17:08] <Chillum> assembly is easier than design
[17:08] <Apocx> true
[17:08] <Chillum> do you have a chip you can recommend?
[17:09] <Chillum> some of the sub hub chips have build in ethernet, through ethernet is such a huge jack I don't think it is worth including
[17:09] <Chillum> s/sub/hub/
[17:09] <Apocx> only chip I've really used it the same on one the Pi 2
[17:09] <mgottschlag> last time I looked, there were almost no usb hs hub chips in QFP packages
[17:09] <Chillum> s/sub/usb/
[17:09] <Chillum> early for me, need coffee
[17:09] <Apocx> (LAN9514)
[17:10] <Chillum> mgottschlag: ya, the ball packages are difficult
[17:10] <mgottschlag> well, the pi's one is QFN, which doesn't have balls but is difficult enough to solder :D
[17:10] <mgottschlag> not really possible anymore with an iron
[17:10] <Chillum> I have paste and a hot air blower, it is pretty good for that kind of thing. Not so good for BGA
[17:11] <Chillum> but I am building an oven
[17:11] <Apocx> yeah you'd need to reflow it
[17:11] <engblom> chesty: Raspbian-Lite
[17:11] <Chillum> the LAN9514 looks like something I could solder. And if it is used in the Pi 2 I can just look at how they wired it in the schematics

[17:12] <Chillum> is the pi even capable of gbit?
[17:12] <Apocx> 1.5Kb/s is fine for most things the Pi would be doing
[17:12] <yoosi> RPi is 1/100 tops
[17:12] <Apocx> USB2 and Gigabit are kind of oxymorons aren't they?

[17:13] <engblom> chesty: The strange thing, now suddenly it began answering both ping and ssh, without me doing anything
[17:13] <Apocx> 480Mbps and all being the cap
[17:13] <mgottschlag> Apocx: you can go much higher than 100Mbit/s though
[17:13] <yoosi> USB with Ethernet is faster than the onboard ethernet
[17:13] <Apocx> true but not gigabit speeds
[17:13] <yoosi> Correct

[17:14] <Apocx> yeah, one of the things I dislike about the Pi honestly
[17:14] <Chillum> I think I will keep it simple, use the chip he chose. Replace on of the USB ports with a wifi dongle. You start with a tiny one, remove the case and solder it directly to the board

[17:15] <Apocx> just a thought :P
[17:15] <Chillum> what type of wifi module do you mean if not usb?
[17:15] <Apocx> I mean a usb wifi module, just one designed to be soldered onto boards
[17:15] <yoosi> WiFi modules can be connected to GPIO
[17:15] <Chillum> ah. Did not know they made those Apocx
[17:16] <Chillum> yoosi: do you mean something like a esp8266?
[17:16] <Apocx> yeah that uses SPI as I recall
[17:16] <Apocx> speeds suffer but then again with USB full speed caps it might not be much different
[17:17] <Chillum> I have a pile of $5 wifi dongles I use for Pis and they work good. Taken apart they are really tiny
[17:17] <yoosi> Chillum: yes
[17:17] <Apocx> use one of those then, whatever is easiest

[17:18] <yoosi> I've never done it myself. I have a drawer full of cheapo USB wlan cards froma bulk eBay order ages ago
[17:18] <Chillum> Apocx: was going to directly solder the two boards together, since i am making the PCB it will be attached to I can customize it
[17:18] <yoosi> Chillum: What is your project?
[17:18] <Apocx> gotcha

To talk to the teensy fast enough I have to use the USB to get 1 megabaud, the GPIO serial is far slower than USB serial. I wish the Pi 2 has usb on the GPIO pins
[17:32] <Chillum> the usb on the test pins is the next best thing
[17:32] <Apocx> Honestly the Pi Zero just feels like a less useful Compute Module

[17:46] <Apocx> I just love the idea of SoM boards. Especially when you can just replace the module when a new one comes out and BAM, your board is instantly faster and better. assuming modules are backwards compatible (which the CM is--or so they claim it will be)
[17:46] <Chillum> I wanted a CM, but the price it too high
[17:46] <Chillum> it seems it was not popular enough to drive the cost down
[17:46] <Apocx> since they still haven't released the second CM >:(
[17:47] <Apocx> $35 isn't bad IMO
[17:47] <Apocx> same price as a regular Pi
[17:47] <Chillum> the zero without the usb/hdmi ports attached would be something I would want
[17:48] <Chillum> since the usb/sd card is broken out into the test pins and everything else is available by GPIO they are not needed for embedded apps

[18:04] <yoosi> methuzla: I'd probably use an Arduino to drive neopixels. I haven't done too much with Raspberry Pi GPIO yet

[18:47] <mgottschlag> methuzla: I think you can ignore them
[18:47] <methuzla> styler2go but these are basically RGB LEDS and controlling them can be done various ways
[18:48] <mgottschlag> not sure though
[18:48] <mgottschlag> usually, some of them are to connect a second sensor
[18:48] <snowkidind> you basically need to get datasheets by getting the part number and scour digikey until you find something repeat until an understanding is gained
[18:49] * weemsledeux (~textual@unaffiliated/weems) has joined #raspberrypi
[18:49] <snowkidind> depends if they have chip on board or are remotely controlled
[18:49] <snowkidind> some of them take a serial signal and you can have independent control of every light
[18:49] <snowkidind> then you need to figure out the specs of the led itself
[18:50] <mgottschlag> styler2go: 24C... sounds like EEPROM memory
[18:50] <snowkidind> what i am guessing is that these are a bit dumber than that
[18:51] * mythos (~mythos@unaffiliated/mythos) has joined #raspberrypi
[18:51] <snowkidind> those are probably current drivers and the stuff under the black hardened gel’ish stuff is probably the microcontroller

[18:51] <styler2go> methuzla: it ha sno other side
[18:52] <snowkidind> what is probably happening is the mcu is telling the current driver to open / close and thats about it so what you need to hack is the 100011101011 that feeds the current driver
[18:53] <snowkidind> so find the spec on the current driver and hijack the input pin and you are in like flynn
[18:53] <Chillum> snowkidind: that makes sense
[18:53] <Chillum> and cdrivers tend to be fine with 3.3v signals, bonus!

[19:05] <mgottschlag> Chillum: yeah, with a metal-programmed microcontroller that might make sense
[19:05] <snowkidind> whats the brand name of leds?
[19:05] <Chillum> my thinking precisely
[19:05] <styler2go> well if it is that complicated i might just buy a different controller
[19:06] <mgottschlag> I'd expect the LEDs to be just dumb RGB LEDs, driven with PWM
[19:06] <styler2go> PWM? power managment?
[19:06] <snowkidind> have you tried looking for a schematic?
[19:06] <mgottschlag> pulse width modulation
[19:06] <styler2go> i knwo that from comptuer fans
[19:06] <mgottschlag> the longer the pulse, the higher the ration of on-time vs off-time and the brighter the LED
[19:06] <mgottschlag> yeah, same principle
[19:06] <mgottschlag> *ratio
[19:07] <mgottschlag> you could easily generate that signal with a pi
[19:07] * nfk|laptop (~nfk@unaffiliated/nfk) has joined #raspberrypi
[19:07] <styler2go> but PWm can't control the color, can it?
[19:07] <snowkidind> worst case you can always get your own current driver and just start from scratch
[19:07] <styler2go> oh wait
[19:07] <mgottschlag> 3x PWM can control all 3 basic colors
[19:07] <styler2go> less power on one color strip = other color
[19:07] <Chillum> ya

[19:09] <Chillum> you can actually take the decimal equivalent of RGB codes for colors(like red #FF0000 = 255,0,0) and apply those values to the pwm.
[19:09] <styler2go> but i cant control that with just the GPIO right?
[19:09] <Chillum> ohh styler2go you could if you wanted to just teach an arduino or Pi to send out IR signals to the existing controller
[19:09] <snowkidind> does pi have a pwm?
[19:10] <Chillum> or is that an rf controller?
[19:10] <mgottschlag> the pi has PWM, but 100Hz-PWM is easily emulated in software
[19:10] <styler2go> snowkidind: looks exactly same
[19:10] <mgottschlag> although under high CPU load software-PWM tends to flicker
[19:10] <styler2go> snowkidind: my Power Supply is 2A tho
[19:10] <snowkidind> ok
[19:11] <gordonDrogon> you can reduce the flicker by running the softPwm task at a higher real-time priority - it's not perfect, but better.
[19:11] <snowkidind> so its no brand
[19:11] <styler2go> yes
[19:12] <gordonDrogon> a Pi with a 40-pin GPIO connector has 2 hardware PWM channels avalilable.

[19:20] <gordonDrogon> meanwhile A+s are still available - not quite a Zero, but more or less...
[19:20] <Chillum> those zeros look reasonable to build yourself. Once they publish the open source hardward schematic and board design on it
[19:20] <gordonDrogon> and can be used to develop a project before replacing it with a zero.
[19:20] <traeak> in fat i bet that people already using original rpi in products love the zero

[19:20] <Apocx> Doesn't hte Pi still use the RAM on CPU design as the Pi 2?
[19:20] <Apocx> Doesn't the Zero*
[19:20] <gordonDrogon> Chillum, and where will you get the SoC from?

[19:21] <gordonDrogon> I think it'd be no worse than using an Arduino to devleop/prototype a project before building it with a dedicated ATmega...
[19:21] <mgottschlag> actually, that RAM-on-CPU design makes designing PCBs much easier :D
[19:21] <Chillum> yes but assembling them?
[19:21] <Apocx> yeah I guess if it came in one package

[19:22] <gordonDrogon> However if you want to build your own, then Farnell will do it for you.
[19:22] <Apocx> Sure, just give them like $50,000
[19:22] <mgottschlag> Chillum: put the RAM onto the CPU, heat it up with hot air, done
[19:22] <mgottschlag> theoretically at least
[19:22] <Chillum> probably

[19:29] <mgottschlag> DoctorD90: btw, the manual of the MPU9250 will tell you
[19:29] <Chillum> nothing evil about hoarding stuff for profit
[19:30] <DoctorD90> mgottschlag, manual? but i get a board...i dont know how it is wired...or yes?
[19:30] <gordonDrogon> DoctorD90, looks like it might be spi .. or I2C... who knows.
[19:30] <mgottschlag> these boards are usually very simple
[19:30] <mgottschlag> if the names match names of pins in the MPU9250 manual, you can be pretty sure that's a direct connection

[19:32] <snowkidind> if there is that much demand for the zero, they will release a better version soon and then hoarders boards will be obsolete

[19:39] <mgottschlag> if you don't, then why are you doing this if you don't even have a multimeter? :p

[19:40] <DoctorD90> in theory i may follow the "wire" on board...but element on it are all tesistence?
[19:40] <gordonDrogon> engblom, no idea - I don't use j.
[19:40] <mgottschlag> DoctorD90: what do you mean?
[19:41] <engblom> < gordonDrogon> engblom, just call the gpio command to export it for you... that'll change ownership for you.
[19:41] <mgottschlag> DoctorD90: actually, a close look at the online photos already gives away most connections
[19:41] <engblom> What do you mean by that line?
[19:41] <DoctorD90> the board has "track" from chip to each element on board, and to pinout. I may try to follow them. but at a certain point I get "elements"..they are all resistence?
[19:42] <DoctorD90> "222"
[19:42] <DoctorD90> mgottschlag, exactly what i was aiming to :)
[19:42] <gordonDrogon> if you run: gpio export $pin then it will export the pin for you and change ownership to the user calling the gpio command.
[19:42] <mgottschlag> the black ones are resistors, the others capacitors

[19:43] * helderc (~helderc@ Quit (Ping timeout: 276 seconds)
[19:44] <mgottschlag> not always, some resistors are pullups/pulldowns and are connected to 3.3V/0V, and the interesting connection is e.g. on the other side of the board
[19:44] <gordonDrogon> back to the bake-house. laters...
[19:44] <DoctorD90> in theory, basing on what i have seen untill now, to use VIN-GND-SDA-SCL.....
[19:45] <DoctorD90> mgottschlag, what do you mean with "some resistor are pullup/pulldown" ?
[19:45] <mgottschlag> basically, you only need to find out what the pins mean which you don't know yet, SDA/SCL are obvious :)
[19:45] <mgottschlag> well
[19:45] <mgottschlag> you know how I2C works, electrically?
[19:45] <DoctorD90> mgottschlag, i would mean to start as basic :D
[19:46] <mgottschlag> pullups pul the wire to 3.3V, and the devices pull it down to 0V (strongly, with a transistor) to send signals
[19:46] <DoctorD90> no electrically no....what i know is: run command to detect device....and send/read data....even if i dont know
[19:46] <mgottschlag> which has the advantage that two sending devices can never create a short circuit if one device sends a 1 and the othe a 0 :)
[19:46] <mgottschlag> (because no device will ever strongly pull towards 3.3V, so there is never a strong connection (short circuit) between 3.3V and 0V
[19:47] <mgottschlag> anyways, such circuits are realized with pullup resistors
[19:47] <snowkidind> question: are the gpio pins pretty much the same deal as desktop motherboards have always had at their lower edge, like where you would hook up the internal speaker, etc...

[19:55] <mgottschlag2> DoctorD90: pullups create something like a "default value"
[19:55] <t3chguy> DoctorD90: pullups also prevent floating voltages
[19:55] <Apocx> GPIO is just a 2x20 row of pin headers that the CPU can utilize (in the case of the Pi)
[19:55] <t3chguy> well, or mitigate against floating voltages

[19:58] <DoctorD90> so i havent to "manually" reset to 3v3 :D
[19:58] <t3chguy> yep DoctorD90 they are a relatively large value resistor, to create a default value as wires without any connections on will float (change voltage based on their environment)
[19:58] <snowkidind> anyone care to point me there?

[20:11] <DoctorD90> t3chguy, what does mean "measure betwee"
[20:11] <mgottschlag2> but you won't be able to measure a resistance across the voltage regulator
[20:11] <t3chguy> DoctorD90: one multimeter probe on SDA/SCL, the other on the 3v3 rail
[20:11] <DoctorD90> ok
[20:12] <DoctorD90> so i have to use only 3v3, and not vin
[20:12] <DoctorD90> or i cant read
[20:12] <mgottschlag2> you can either put 3.3V to 3V3, or put 5V to VIN, both will work
[20:13] <mgottschlag2> (but not both at the same time)
[20:13] <Chillum> those unpopulated pads with solder on them on the top of the pizero just under the raspberry logo look like jumper pads
[20:13] <DoctorD90> ah that is ok...i gotcha this: to put voltage, i may to put 3-5v to vin OR 3v3 in 3v3. GND to GND....now is time to sda scl
[20:14] <mgottschlag2> and I would strongly suggest that you use VIN, and not 3V3, because some regulators don't like to be backpowered
[20:14] <DoctorD90> so i will use VIN, and not 3v3..thx for sugegst
[20:14] <DoctorD90> backpowered measn shutdown ?
[20:14] <DoctorD90> means*
[20:15] <Chillum> also the microsd card won't be happy with 3.3
[20:15] <mgottschlag2> well, powered through their power *output*

[20:16] <mgottschlag2> DoctorD90: well, what I mean is that some regulators are damaged when you put power to their output, but not their input
[20:16] * drewx0r (~drewx0r@unaffiliated/drewx0r) has joined #raspberrypi
[20:16] <mgottschlag2> modern regulators usually don't do that anymore though
[20:16] <mgottschlag2> Chillum: the unpopulated parts to me look like space for a linear regulator
[20:17] <mgottschlag2> or a USB power switch
[20:17] <mgottschlag2> as they are sitting between the power USB connector and the 5V pin of the OTG connector

[20:19] <DoctorD90> mgottschlag2, ok, so i will use *only* 3v3 (only, by defaults, if manual doesnt sy other stuff)
[20:20] <mgottschlag2> no, only VIN
[20:20] <DoctorD90> oh yes. sorry mistype
[20:20] <DoctorD90> only vin
[20:20] <DoctorD90> sorry !
[20:21] * h4ndy is now known as H4ndy
[20:21] <DoctorD90> and between vcc(from what i have understand is the same of vin) and sda, and vcc/scl, i wil put a resistor
[20:21] <t3chguy> DoctorD90: don't do that
[20:22] <t3chguy> pulling the SDA/SCL to 5V might fry your Raspberry Pi
[20:22] <DoctorD90> T_T im not understanding nothing anymore xD
[20:22] <t3chguy> it should be pulled to 3v3
[20:22] <t3chguy> it is likely there is already a resistor for this purpose on the board
[20:22] <t3chguy> thats why mgottschlag2 and I said MEASURE
[20:22] <DoctorD90> t3chguy, i connect 3v3 from rpi to vin 0o
[20:22] <t3chguy> no DoctorD90 , 5V to VIN
[20:22] <deshipu> t3chguy: the pullups on the pi are weak
[20:23] <t3chguy> deshipu: I meant on the device as in the slave device/peripheral
[20:23] <deshipu> slaves usually don't have pullups
[20:23] <DoctorD90> t3chguy, why i cant use directly 3v3 from pi? 0o and i have to use 5v? 0o
[20:24] <DoctorD90> because with a resistor it may change ?
[20:24] <t3chguy> DoctorD90: if its using a Voltage regulator to 3v3 then supplying 3v3 to VIN won't work
[20:24] <t3chguy> as a Voltage Regulator won't boost the voltage
[20:24] <t3chguy> only drop it
[20:24] <mgottschlag2> deshipu: these boards usually do, and the photos also look as if there were pullups
[20:25] <DoctorD90> ok, so i put 3v3, +resistor + voltage regulator......less than 3v3...so i use 5v :) ok
[20:25] <mgottschlag2> anyways, I'm off for today, gn8
[20:25] <DoctorD90> many thnks mgottschlag2 :D
[20:25] <DoctorD90> good nigth!!!

[20:25] <DoctorD90> t3chguy, may I continue discussion with you? :)
[20:25] <t3chguy> DoctorD90: don't put a series resistor in VIN
[20:26] <t3chguy> that will limit the current the device can use, and also drop voltage
[20:26] <t3chguy> the I²C Pull UP Resistors go between 3v3 and SCL and 3v3 and SDA
[20:26] <DoctorD90> so i havent to follw that image: http://quick2wire.com/wp-content/uploads/2012/05/image00.png
[20:26] <t3chguy> to create a PULL UP
[20:26] <t3chguy> that image doesn't put the resistors in series with VIN as you suggested
[20:27] <t3chguy> I actually have the exact module you are looking at buying
[20:27] <DoctorD90> 1 resistor between vcc, and 1ressitor between vcc and scl
[20:27] <t3chguy> I will check whether it has on-board pull ups

[20:29] * mgottschlag (~quassel@reactos/tester/phoenix64) Quit (Ping timeout: 246 seconds)
[20:29] <t3chguy> so you can forget about pull ups
[20:29] <t3chguy> as the board already has them
[20:30] <t3chguy> you just connect 3v3 (or VIN to 5V), GND, SCL and SDA
[20:30] <DoctorD90> no....
[20:30] <DoctorD90> if i connect 5v to 3v3 i will fry the board?
[20:31] <DoctorD90> so 5v only to VIN, and 3v3 MAYBE only to 3v3
[20:31] * AbouEmre (~Thunderbi@ Quit (Ping timeout: 245 seconds)
[20:32] <t3chguy> I said VIN...
[20:32] <t3chguy> if you use 3v3 then obviously connect 3.3v to it
[20:32] <t3chguy> if you use VIN then 5V to it
[20:32] <t3chguy> but don't connect both, one or the other
[20:33] <DoctorD90> ok :D so im sure i have understand now :D
[20:33] <DoctorD90> great
[20:33] <DoctorD90> !
[20:33] <t3chguy> I made a diagram for you

[20:40] <t3chguy> they're entirely different protocols

[20:40] * taza (~taza@unaffiliated/taza) has joined #raspberrypi
[20:40] <t3chguy> but SPI uses n+3 wires

[20:43] <t3chguy> I have a few OLED screens which use I²C pin names for an SPI Breakout, just makes is hella confusing
[20:43] <t3chguy> if you don't have a datasheet, I'd stick to I²C, you're also more likely to find someone's work using I²C for that chip

[20:45] <DoctorD90> i have find out the manual for the CHIP, but not the manual for entire board :P chinese-stuffes :P
[20:46] <t3chguy> just remember, if its SPI (on both chips), it'll be 3+2 (5) SPI Wires + 2 Vcc+GND
[20:46] <t3chguy> and there's barely that many pins on the breakout
[20:47] <t3chguy> so I doubt it supports both SPI and I²C, the chips probably do, but the pins for those protocols may not be soldered to any of the breakout pins

[23:50] <sgflt> mozzwald, i guess that's it. without having a working version to compare against and no 4.7k, i'll have to assume that's the issue
[23:51] <sgflt> mozzwald, no, i only brought 4x 120 because i was hacking on a CAN bus. all the other electronics stuff is at home
