[3:00] <peepsalot> so is there any mirror?

[4:31] <stiv> last i looked pi was 3 volts
[4:31] <piesquared> Really?
[4:32] <piesquared> The output?
[4:32] <piesquared> Or input.
[4:32] <stiv> yeah. i could be wrong. go find a data sheet
[4:33] <piesquared> ...
[4:33] <stiv> who ya gonna believe - some anonymous random on the interwebs or the data sheet?
[4:34] <stiv> unless it was gordonDrogon. i'd believe him
[4:34] <piesquared> iI need it to power... 5 servos off and on... and 2 motors pretty much all the time.
[4:34] <piesquared> He write the datasheets?

[4:35] * Vonter (~Vonter@49.206.12.140) has joined #raspberrypi
[4:35] <piesquared> Grr no, it wont power the motora.
[4:35] <piesquared> Its late..
[4:35] <stiv> he wrote WiringPi lib, so i'm thinking he knows something about pi i/o
[4:36] <stiv> to drive motors & servos, you generally need some sort of driver board

[4:36] <stiv> pi does not put out a lot of power
[4:36] <piesquared> yah.
[4:37] <piesquared> I know... i need to go to bed. A few weeks with little sleep doesnt go well with the brain.
[4:37] <stiv> sleep is good for you
[4:38] <piesquared> Ive figured that iut the hard way. :P

[4:55] <arahael> piesquared: Pairing an arduino with a Pi isn't crazy, it would infact simplify this as the arduino gives you a potentially hard-realtime system.
[4:55] <swift110> goodness that sounds cool
[4:55] <swift110> anyone build a weather station with a pi yet?
[4:55] <arahael> piesquared: And is more common than you'd think - the arduino is absurdely trivial, whereas the Pi is effectively a modern computer.
[4:55] <piesquared> Maybe.
[4:55] * fredp (~fredp@unaffiliated/fredp) has joined #raspberrypi

[8:02] <stiv> a battery charger and a power supply are two different use cases, with different requirements
[8:02] <stiv> in both cases you start with a sine wave at mains voltage.
[8:03] <stiv> a power supply will give you a clean, steady 5V DC
[8:06] <stiv> a battery charger just needs to rectify the AC to DC and maybe filter it a bit. as long as the voltage occasion gets high enough to push electrons into the battery, that's good enough.

[9:12] <chris_99> sorry i'm confused, isn't 36, a 5GHz channel or am i mistaken

[9:13] * ziddey (~ziddey@ool-182dd7c7.dyn.optonline.net) has joined #raspberrypi
[9:14] <chris_99> yeah but 36 is 5GHz isn't it according to this
[9:14] <chris_99> https://en.wikipedia.org/wiki/List_of_WLAN_channels
[9:14] <chris_99> sorry i understand there are multiple freqs around 5GHz
[9:14] <Lartza> It's... one of the 5ghz channels
[9:14] <chris_99> mm
[9:15] <chris_99> hmm actually
[9:15] <chris_99> may it's not 36 i want
[9:15] <mfa298> I'm not sure you can fix the frequency on 5ghz in quite the same way - you can certainly limit which bands are used (some are indoor only, some need a license)
[9:15] <chris_99> for ac
[9:15] <chris_99> you can use a fixed channel for 5ghz
[9:15] <chris_99> in that, i could set it on my ap
[9:15] <Lartza> You should be able to yes, and routers should choose the best one automatically
[9:16] <Lartza> And fix to that
[9:16] <chris_99> actually 36
[9:16] <chris_99> may not be an ac achannel

[9:16] <chris_99> look at the bandwidth
[9:17] <Lartza> Yes?
[9:17] <chris_99> ' Optional 160 MHz and mandatory 80 MHz channel bandwidth for stations; cf. 40 MHz maximum in 802.11n.' re. ac
[9:17] * sigsts (~sigsts@unaffiliated/skyroverr) Quit (Read error: Connection reset by peer)
[9:18] <Lartza> Where are you reading that?
[9:18] <chris_99> https://en.wikipedia.org/wiki/IEEE_802.11ac
[9:19] <mfa298> from memory 5ghz mandates the use of dfs which means the ap and clients need to be able to move channel in some cases or shutdown if there's no suitable channel
[9:19] <Lartza> Well no, 36 can still be ac
[9:20] <chris_99> i'm confused why that table says 36 is 20MHz bandwidth then
[9:20] <chris_99> unless it's not always 20
[9:21] <Lartza> It is
[9:21] <mfa298> if it's like 11n, you combine multiple channels for the higher bandwidth options.
[9:21] <chris_99> ahh
[9:22] <Lartza> Also you have the addedd support for 80mhz

[9:23] <Lartza> If you're thinking 40mhz is 36+40
[9:23] <Lartza> on ac that's just 38
[9:23] <Lartza> chris_99, Like you said, mandatory support for 80mhz, optional support for 160mhz
[9:23] <Lartza> That's in addition to 20 and 40, not exclusively
[9:23] <chris_99> i'm not sure what you mean, if 80MHz is mandatory?
[9:24] <Lartza> It is, mandatory to support
[9:24] <chris_99> i shouldn't have to do anything to use it appart from pick the right channel
[9:24] <Lartza> You don't no
[9:24] <Lartza> Honestly, you should be able to just let your devices pick it
[9:24] <Lartza> But either way
[9:24] <chris_99> i'm trying to use it via a mesh, so i do need to
[9:25] <Lartza> Well yeah, but either way channel 36 is a 20mhz channel and can be 802.11ac
[9:26] <chris_99> ok, i'll see if i can use 42 as that's 80

[10:34] <ShorTie> gordonDrogon has done it very well in wiringPi, that is what i use
[10:34] * sigsts (~sigsts@unaffiliated/skyroverr) has joined #raspberrypi
[10:37] <mfa298> DJDan: spi usually needs mosi (master out slave in), miso (master in slave out), sclk (clock) and ce<n> (chip select, sometimes called other things)
[10:38] <mfa298> the master (the pi) enables a slave with the correct chip select and sends a command to which the slave replies
[10:39] <ShorTie> and some spi devices have mosi and miso defined backwards from the way you think, so you gotta switch them to work
[10:41] <DJDan> i was told i needed MOSI, XCS, SCK and GND from the other unit into the RPI3.... im not sure how to fully read now the values coming into the RPI3
[10:42] <DJDan> theres 26 bytes ... last 26 byte being a checksum crc packet.. and 7 lots of 26 byte packets
[10:42] <DJDan> but i dont know how to read it
[10:48] <gordonDrogon> SPI sends and recieves at the same time. 26 bytes out is 26 bytes in, bit for bit at the same time.
[10:49] <gordonDrogon> XCS is CS or CE depending on terminology. It's the remote device enable input. normally active low.

[10:49] <mfa298> if you've only got mosi I don't think your going to get data from that device, from memory the pi can only be a master so data into the pi would be over miso

[11:10] <DJDan> (i want the PI to just read the data only... not send back to the CDJ)
[11:11] <mfa298> in all the spi devices I've used you need to send data first to get anything back. i.e. you send a command and then read the results back.
[11:12] <mfa298> what you're describing sounds more like the device is streaming data continuously which isnt how spi normally gets used
[11:12] <artok> aren't cdj's using ethernet udp ?
[11:12] <DJDan> mfa298: the unit is streaming spi data continously to a LCD screen generally yes
[11:12] <DJDan> artok: very old unit lol :P
[11:13] <mfa298> which is why I asked if its spi, as I don't see much in there that says what it is

[11:19] <DJDan> yes from the CDJ to the RPI3
[11:19] <mfa298> which (if its spi) is probably the master, and the pi can only be the master, which means its unlikely to work

[11:20] <DJDan> mfa298: the internal screen does come up with a error code when attached to the pi.. which is why i was trying to remove going from pi back to CDJ
[11:20] <DJDan> i am trying to get it to go both to the internal screen and my PI..

[11:24] <artok> it isn't hardware limitation that rpi isn't SPI slave, right?

[11:27] <DJDan> SPI0...
[11:27] <mfa298> remember the sclk pi on the pi is an output pin
[11:27] <mfa298> .... answer you can't as the pi isn't an spi slave
[11:28] <DJDan> mfa298: i dont understand, how do i do it
[11:29] <mfa298> i don't think you can. to "spy" on the data you need an spi slave, which I don't think the pi can do.
[11:29] <DJDan> im using mosi, miso, sclck and ce0, and gnd on the pi
[11:30] <DJDan> "The Pi contains hardware to support SPI in a slave mode " apparently
[11:30] <DJDan> the rpi3 has 2 spis
[11:30] <DJDan> only using CE0 i think tho
[11:31] <mfa298> the pi has the spi enable pins (ce0 and ce1) to it can select which slave to use the clock, miso and mosi are shared
[11:33] <chris_99> i'm just wondering, i'm prbably missing something, but if i'm part of the kmem group i should be able to cat /dev/mem right? i get permission denied. (i understand the security issue here)

[11:34] <mfa298> DJDan: 09:29 < mfa298> i don't think you can.
[11:35] <mfa298> you need an spi slave. - I don't think thats something the pi can do
[11:35] <arahael> chris_99: /dev/mem is raw memory, isn't it?
[11:35] <chris_99> yeah

[12:10] <mfa298> DJDan: good luck with something that doesn't look to have been updated in 4 years and is probably userspace
[12:10] <artok> actually that might switch the clock pin as slave
[12:10] <artok> but to do that with your current kernel
[12:10] <DJDan> so are u saying with that, i can use SCLK pin as input instead? or should the sclk be moved
[12:11] <artok> you need to get clock from master to get the data
[12:12] <artok> but as said, old stuff from the internet vs your current system, we are talking about "good luck with coding"
[12:12] <DJDan> well at the moment MOSI, MISO, XCS, SCLK and XCS are coming to the RPI3... except SCLK currently is obviously wrong as its apparently outputs not input...

[12:59] <ShorTie> gordonDrogon has done it very well in wiringPi, that is what i use
[13:00] <gordonDrogon> you can't 'snoop' because the Pi is SPI master only.
[13:00] <DJDan> gordonDrogon: yeah, i realise.. im trying to change it to slave somehow
[13:01] <artok> somehow you need to make kernel module =)

[13:02] <DJDan> gordonDrogon: im not entirely sure what txd and rxd are used for.. that could be for the CD Player
[13:03] <ShorTie> plain old serial makes more sence for that thing any ways, imho
[13:03] <chris_99> coudln't you sniff data just by sampling gpio pins?
[13:03] <DJDan> im just trying to read the SPI Data that is going to the internal lcd
[13:03] <chris_99> dunno what speed that would give you though
[13:03] <DJDan> i can see some spi data.. with the basic c tester...
[13:03] <DJDan> ./spidev_test -D /dev/spidev0.0
[13:04] <DJDan> it keeps changing
[13:04] <chris_99> i missed what you're trying to do, you're sniffing data from what
[13:04] <DJDan> chris_99: a CDJ 1000 MK3 cd deck...
[13:04] <DJDan> https://drive.google.com/open?id=0B8FarhJkT4w_Q2Z1d1pydFdtQzQ
[13:04] <chris_99> ok, and the cd deck is talking to what at the mo?
[13:05] <DJDan> chris_99: it is trying to talk to a internal lcd screen...but now errors.. because im trying to read the data on my RPI3 via spi0
[13:05] <DJDan> there is some sort of data changing on spi0
[13:05] <chris_99> ahh you might be best with a cheapo logic analyser
[13:05] <chris_99> i got a 100MHz one pretty cheap
[13:06] * artok is happily DJ'ing with NI Traktor and getting enough data from that ;)
[13:06] <DJDan> i think its actually read the data
[13:06] <DJDan> cause it keeps changing so it might be doing something
[13:07] <DJDan> artok: yes yes, i can dj with good cdjs too.. except i want the SPI from these CDJs :P

[13:07] <DJDan> if ./spidev_test -D /dev/spidev0.0 keeps changing... i think spi0 may work
[13:08] <artok> well then you just try to parse that data
[13:08] <DJDan> well then whats with the sclk.. cause u guys said the sclk on the rpi is output not input
[13:08] <chris_99> i'm just wondering, with spi, are you sending data then to get data, since its a master
[13:09] * EdLin (~edlin@securabit/listener/edlin) Quit (Quit: Leaving)
[13:09] <DJDan> chris_99: i dunno.. but it constantly sends spi data to the internal cdj screen
[13:09] <mfa298> getting data and getting useful data are two very seperate things. Chances are you would see some data with nothing connexted (or maybe just a wire on the pin not connected at the other end)
[13:09] <DJDan> im just wanting to spy/read data from the line, without the internal screen erroring
[13:10] <DJDan> if i remove the sclk do you reckon the internal screen will work
[13:10] <chris_99> yeah that's what i'm thinking mfa298 , i'm wondering if they're sending data with spi, and it's then returning data from the cd player, but the clock isn't gonna be synced to the player
[13:11] <DJDan> well given the sclk port is currently output not input.... and i wired the sclk from the cdj to the rpi sclk.... its confused
[13:11] <mfa298> chris_99: we've been over this with him for the last three hours.
[13:11] <chris_99> ah
[13:12] <chris_99> let me link to to the logic analyser i have
[13:13] <DJDan> chris_99: are u talking about something like... https://github.com/superzerg/logic-analyzer ?

[13:15] <chris_99> it's able to stream data via usb
[13:15] <chris_99> i use sigrok with it

[13:18] <DJDan> gordonDrogon: is there a way with wiringpi, to make the SCLK become input/SPI Slave.. rather then Master..
[13:18] <chris_99> no it's not really similar to the pi3, that can sample at around 100MHz on 3 channels, and stream the data via usb
[13:21] <DJDan> if i can workout how to get sclk to be slave not master, it would probably fix my problems

[13:49] <ShorTie> i've looked at that several times
[13:49] <ShorTie> see no spi reference anywhere to tell the truth
[13:49] <ShorTie> or spi device
[13:50] <DJDan> i was told. E-8709 is a communication error between the computer and the main grid. First, return the CDJ to the working state. this error should not be, when the player is connected according to the original scheme, without STM and Rpi. If you want to spy on the data that comes from the main assy to the display controller, then you will only need to use the MOSI XSC SCK and GND signals on

[19:11] <brianx> DJDan: you need a device designed for spying on the SPI bus. Bus Pirate V3 is such a device. i do agree with you that the hardware for doing this is already present in the bcm2835, but since there is no software that uses it, making use of that hardware is not practical. Bus Pirate V3 has all that software already (plus can do a lot of other things) in a reasonably priced device.

[19:48] <OO-Dragon> please don't hack it :P its not ready for hack testing
[19:48] <OO-Dragon> but does auto populate values in yellow
[19:49] <OO-Dragon> from the actual sensors (over the wireless)
[19:49] <OO-Dragon> the wierd colour after "Colour:" is the actual rbg values put into the actual colour shown after
[19:49] <OO-Dragon> so that's apparently the colour of the light hitting the sensors
[19:51] <OO-Dragon> I find it pretty fun to convert the real world into digital information to analyze.
[19:52] <OO-Dragon> chris_99, what are you using to code the sensor? python?
[19:52] <chris_99> it just connects to the Pis UART atm, i'm using C
[19:53] <chris_99> i've also got this https://www.adafruit.com/product/2857 which gives a nice humdity/temp graph, which is roughly the inverse of each other
[19:54] <OO-Dragon> ahh OK. nice.
[19:54] <chris_99> i need to get some capacitive soil moisture sensors working too
[19:54] <OO-Dragon> I'm realizing that adafruit appears to be a goto place for much DIY hardware stuff
[19:55] <OO-Dragon> actually I need to do that too for my wife. She wants to do more automated gardnening, so I'll need sensors to monitor that stuff to auto feed / water

[19:56] <chris_99> https://www.ebay.co.uk/itm/Analog-Capacitive-Soil-Moisture-Sensor-V1-2-Corrosion-Resistant-Cable-Wire-/352348037249 and i'll hook it up to an I2C ADC
[19:56] <chris_99> cool not seen that
[19:57] <chris_99> that actually just uses a 555 timer interestingly
[19:57] <OO-Dragon> the temp is not accurate, due to being too close to CPU, but I'm pretty sure you can actually adjust for that. As I was able to find a consistent range difference on the Pi zero /w the Enviro sensor
[19:58] <OO-Dragon> that capacitive soil sensor looks pretty good actually.

[20:03] <OO-Dragon> that's cool
[20:03] <akk> What do modern cars do with their radio key fobs? The Volt is remarkably good about figuring out who is sitting/standing where inside or near the car.

[20:04] <OO-Dragon> I think detecting wifi broacasts would probably be more accurate, if you can get to the low level

[20:19] <OO-Dragon> but if you can get something similar, but get and manipulate the readings, you could start to find cool paterns that match up to things like, distance, speed, type of device, etc

[20:22] <Tenacious-Techhu> Anyone know anything about salvaging SD Card installs?
[20:23] <OO-Dragon> Tenacious-Techhu, Yep, one sec
[20:23] <OO-Dragon> Tenacious-Techhu, https://www.ccleaner.com/recuva
[20:23] <OO-Dragon> To get data off a SD card
[20:24] <chris_99> or dd,testdisk/photorec too
[20:24] <OO-Dragon> Or did you just want to fix a non-booting SD card?
[20:24] <CoJaBo> Define "salvaging", first lol
[20:25] <CoJaBo> 99% of the time, you just reinstall >_>

[20:29] * taza (~taza@unaffiliated/taza) has joined #raspberrypi
[20:29] <OO-Dragon> chris_99, THanks! You just gave me things to look over and consider for future projects :)
[20:30] <chris_99> rtlsdr is a nice device to play with btw
[20:30] <CoJaBo> OO-Dragon: I got to use one of those once; don't think it was that brand, but it was really cool
[20:31] <CoJaBo> It did more than just wifi tho
[20:32] <OO-Dragon> Nice, makes me wonder just how much of the spectrum a device could cover AND handle.. I'm guessing you would probably just add different chips for different requency ranges
[20:32] <chris_99> you can get sdrs with crazy bandwidth
[20:32] <chris_99> i've got one that has around 40MHz bandwidth iirc
[20:33] <chris_99> but iirc you can get some with a GHz
[20:33] <CoJaBo> The thing looked like a really thicck Gameboy, complete with the screen and button arrangement
[20:33] <CoJaBo> It could do pretty much any video format, and I think that's the main thing it was sold for
[20:33] <OO-Dragon> cool, on both fronts
[20:33] <shauno> I think the main bandwidth limitation on cheap sdrs at the moment is usb2
[20:33] <CoJaBo> (It's also priced in the 5-figure range)
[20:34] <OO-Dragon> CoJaBo, ouch, yeah, tad pricy
[20:34] <Tenacious-Techhu> My goal is to salvage the install; the SD Card does not boot. I don't need to be told that reinstalling is easier; I'm trying to confirm why the card failed to begin with, and fix it, if possible.
[20:35] <OO-Dragon> maybe we can create a Raspberry Pi equivelant for a bit less :)
[20:35] <CoJaBo> I'm told one of the things they use it for is bug-sweeping for paranoid people
[20:35] <OO-Dragon> Tenacious-Techhu, I would recommend running a check disk on it first then, as file system corruption is common on Pi's when they are not safely shutdown first
[20:35] <OO-Dragon> a checkdisk can often fix those error
[20:36] <OO-Dragon> I just don't remember the command line in linux ...
[20:36] <OO-Dragon> however, download a ISO of ubuntu, boot off it live on a computer with a SD card reader, put your card in
[20:36] <OO-Dragon> then goto "Disks" in the menu
[20:36] <CoJaBo> fsck is the command
[20:37] <chris_99> shauno: yeah, i managed to pick up a usb3 sdr pretty cheaply somehow from fleabay
[20:37] <OO-Dragon> and from there you should be able to see your SD card and I'm pretty sure a button to fix it. If it doesn't show at all, it may be a dead SD card \

[20:47] <chris_99> mm that's true
[20:47] <shauno> fsck is filesystem check. sda doesn't contain a filesystem, it contains a partition map (where sda1&2 are defined)
[20:47] <chris_99> although it can be iirc i'm sure
[20:47] <chris_99> i created an ext fs on /dev/sda heh
[20:48] * guideline (guideline@gateway/vpn/privateinternetaccess/guideline) has joined #raspberrypi
[20:48] <brianx> yes, you can either create a partition table or a filesystem on sda, but not both.
[20:48] <pwillard> sda1 and sda2 LIVE on device sda... right
[20:48] <Tenacious-Techhu> brianx, does that mean the problem, if any, is only with sda1 and 2?
[20:48] <chris_99> brianx: yeah true
[20:48] * taza (~taza@unaffiliated/taza) has joined #raspberrypi
[20:49] <brianx> Tenacious-Techhu: yes. if you have a partition table, the OS will create devices /dev/sda1 and /dev/sda2 (,etc)

[23:18] <OO-Dragon> http://server.dragonwarz.net:8555/
[23:18] <OO-Dragon> that's a demo I have running
[23:18] <OO-Dragon> basically put sensors around, record the sensor readings every 5 min to a file, then I'll analyze it later
[23:18] * dreamon__ (~dreamon@unaffiliated/dreamon) Quit (Ping timeout: 265 seconds)
[23:18] <chris_99> what ae the sensors?
[23:18] <Alvaros> oh nice OO-Dragon that is brilliant!!!
[23:18] <OO-Dragon> that page is just my webapp so we can see live readdings
[23:18] <chris_99> i mean what are they connected to, a microcontroller?
[23:19] <OO-Dragon> Raspberry Pi zero W
[23:19] <chris_99> ah cool
[23:19] <OO-Dragon> I'm using these sensors
[23:19] <OO-Dragon> http://docs.pimoroni.com/envirophat/
[23:19] <OO-Dragon> its a hat that fits perfectly on the Pi zero
[23:19] <chris_99> how are the sensors sending the data
[23:19] <OO-Dragon> yep
[23:20] <OO-Dragon> they are connected to a seperate mini wifi router
[23:20] <chris_99> sorry i mean what protocol
[23:20] <OO-Dragon> and I VPN into that router, to get stuff
[23:20] <OO-Dragon> o
[23:20] <OO-Dragon> sockets in python
[23:20] <OO-Dragon> i send it as a string
[23:20] <chris_99> ah gotcha cool
[23:21] <OO-Dragon> but for downloading the files, I have a http server
[23:21] <OO-Dragon> i just havn't actually made the code work in the web app
[23:21] <Alvaros> photo of them?
[23:21] <OO-Dragon> works in my guizero python app though
[23:21] <OO-Dragon> sure, one sec

[23:22] <OO-Dragon> one sec to get pic of a sensor
[23:23] <Alvaros> very very nice graphs

[23:24] * immibis (~chatzilla@222-155-163-212-fibre.sparkbb.co.nz) has joined #raspberrypi
[23:24] <chris_99> heh neat did you make a GUI python app?
[23:24] <OO-Dragon> matlab python library
[23:25] <chris_99> matplotlib? you mean
[23:25] <OO-Dragon> yep, made it with guizero (nice tutorial on raspberrypi site)
[23:25] <OO-Dragon> yep that's the one
[23:25] <chris_99> cool, matplotlib is pretty awesome
[23:26] <Alvaros> love matplotlib - ive used it on a number of projects :)
[23:26] <OO-Dragon> it made it easy. but I did get stuck when the first line is blank (due to my import logic). because it doesn't not plot... it just plots randomly it seems
[23:26] <OO-Dragon> but sorted that out after awhile

[23:27] <OO-Dragon> sensor pic: http://dragonwarz.net/wp-content/uploads/2018/07/PiZWSensor.jpg
[23:28] <OO-Dragon> its 2 fully built sensors with just the sensor top leaned on one.
[23:28] <chris_99> neat, its got a barometer too?
[23:28] <OO-Dragon> its got a fair amount, let me get link...

[23:29] <OO-Dragon> https://shop.pimoroni.com/products/enviro-phat
[23:29] <OO-Dragon> listed under features. but it also has a place to attach your own, which I plan to attach a air quality sensor to
[23:29] <Alvaros> oh that is really neat
[23:29] <OO-Dragon> then put them out around my area
[23:29] <Alvaros> cool module OO-Dragon
[23:30] <OO-Dragon> I'm also looking at making them self sustaining, so I can put a solar pannel and a USB battery bank to keep it going indefinately.
[23:30] * r0Oter is now known as r00ter
[23:30] <chris_99> nice
[23:31] <OO-Dragon> unfortanetly, you can't charge a USB bank and use at the same time, but I have found a mini controller that can do both (in theory). I'm just waiting for them to get here.
[23:31] <chris_99> i think people where talking about that the other day, i think someone mentioned one that can do that?
[23:35] <OO-Dragon> http://juiceboxzero.com/ that's the one I'm going to test
[23:35] <OO-Dragon> for a few reasons
[23:35] * davr0s (~textual@host81-155-68-151.range81-155.btcentralplus.com) has joined #raspberrypi
[23:35] <OO-Dragon> 1. It fits perfectly on the Pi zero. 2. It will seperate the pi CPU heat more so from the sensors (I have to adjust by 4.5c right now)
[23:36] <chris_99> cool
[23:37] <OO-Dragon> so when the solar is working, it will run the pi and charge the battery at the same time. When not, it runs on battery (overnight)'
[23:37] <chris_99> are they outside then
[23:37] <OO-Dragon> There are a few things I still have to work out, but I think I'll figure it out :)
[23:37] <chris_99> i guess
[23:38] <OO-Dragon> right now, I have 1 in my shed (sensor03), one in my office (sensor01), another on my porch (sensor04) and on in my back office (sensor05)
[23:39] <OO-Dragon> when ever you goto the site, the data is re-freshed.
[23:40] <OO-Dragon> so Alvaros are you working on a Pi project?

[23:52] <lopta> I should download a new OS image tonight, perhaps I'll get to try it tomorrow.
