[1:30] * puff (~user@c-24-3-112-94.hsd1.pa.comcast.net) has joined #raspberrypi
[1:30] <GenteelBen> NUC prices are too damn high!
[1:30] * teepee (~teepee@unaffiliated/teepee) has joined #raspberrypi
[1:30] <GenteelBen> Also their TDPs are too damn high!
[1:30] <GenteelBen> I want a modern single board computer, but they don't exist.
[1:30] <GenteelBen> So the choice is either an RPi, a NUC, or a mini-ITX whitebox.
[1:31] <red_pandabear> The vega nuc is tempting, but holy mother of pricing
[1:31] <GenteelBen> u want dat nucc
[1:31] <red_pandabear> i have a mitx build but the fan noise annoys me :P
[1:31] * genr8__ (~genr8_@unaffiliated/genbtc) has joined #raspberrypi
[1:31] <GenteelBen> Mini ITX can easily be silent, assuming you underclock/undervolt.
[1:32] <GenteelBen> Low-TDP CPUs are a scam, unless they drop below 35W.
[1:32] <red_pandabear> It's got a ryzen apu

[1:33] <red_pandabear> I'm very happy with the rpi though, it sort of does what i need it to do, and it's all silent
[1:33] <dogbert_2> anyone got a recommendation for a KVM for a wireless keyboard and mouse for a desktop PC and a RPi or Clone?
[1:35] * genr8___ (~genr8_@unaffiliated/genbtc) Quit (Ping timeout: 256 seconds)
[1:35] <Tex_Nick> red_pandabear: LOL @ "sort of does", that's the nature of technology, it does great stuff for us, but never everything we want ;-)
[1:36] <red_pandabear> Yep Tex_Nick There are compromises, but it's not too bad.. It's done mostly everything but play videos nicely
[1:36] <red_pandabear> It behaves if i use kodi, but i want VLC to work
[1:36] * raynold (uid201163@gateway/web/irccloud.com/x-eeguqhezxhkdenbp) has joined #raspberrypi
[1:36] <Tex_Nick> yeah Ha
[1:39] <GenteelBen> red_pandabearq: a Ryzen APU, or an Intel+AMD combo CPU+GPU?
[1:39] <ali1234> what is the lowest TDP intel CPU that you can put in a socket? all the really low TDP stuff seems to be only available soldered to a motherboard - which doesn't fit standard heat sinks
[1:39] <GenteelBen> The Intel part isn't actually integrated graphics - the Vega core + 4GB of HMB2 is on-die and connected to the CPU via a PCIe link.
[1:39] <red_pandabear> Ryzen 5 2400G, Vega Graphics
[1:39] <GenteelBen> ali1234: probably 35W these days, let me check. Their 15W parts are all BGA, that much I know.
[1:40] <ali1234> that's pretty much what i found too
[1:40] <ali1234> i guess underclocking would work though. probably those 15W ones are just underclocked and locked
[1:40] <GenteelBen> Lowest seems to be 35W, ali1234.
[1:41] <GenteelBen> The 15W ones can sometimes have a cTDP of like 20W I think?
[1:41] <GenteelBen> It's a configurable TDP, goes up and down depending on what the laptop maker wants.
[1:41] <ali1234> makes sense. i'm looking at mITX board with integrated CPUs though
[1:42] <Tex_Nick> red_pandabear: i'm using a 3B as a psudo-NAS & it will stream a 1080p video to another LAN box jusy fine, but as you day, it won't play the videos well at all
[1:42] <ali1234> vs mITX with a socket
[1:42] <ali1234> for a fanless and small build
[1:42] <GenteelBen> For low-TDP, the surest bet is to buy a G4900T @ 35W. Dual-core, 2.9GHz.
[1:42] <GenteelBen> It's not unlocked, so you can't underclock it.
[1:42] <ali1234> huh, they don't even let you underclock?
[1:42] <red_pandabear> Tex_Nick, it does well in kodi though.. but i can't multitask with that running :P
[1:43] <ali1234> i didn't know that
[1:44] <GenteelBen> The G4900T has a cDTP of 25W too, so an OEM can ship it underclocked/undervolted.
[1:44] <GenteelBen> You could check to see if the board supports configurable TDP.
[1:45] <ali1234> good to know, thanks
[1:45] <Tex_Nick> red_pandabear: ahhh cool i haven't load up kodi ... i've just never really liked xbmc/kodi or plex, kinda too much eye-candy for me
[1:45] <GenteelBen> That being said, single-board computers aren't socketed...so you could just buy a mobile-based "mini desktop".
[1:45] <GenteelBen> Tex_Nick: Kodi is good except for the name.
[1:45] <red_pandabear> Tex_Nick, yeah i agree, it's way too home theatre-y for me.. I like VLC :D
[1:45] <ali1234> i want to use a PCIe tuner card
[1:45] <Tex_Nick> GenteelBen: LOL ;-)
[1:46] <ali1234> it's low profile, but obviously it needs a slot and room in the case, so NUC is out

[1:47] * genr8___ (~genr8_@unaffiliated/genbtc) has joined #raspberrypi
[1:48] <GenteelBen> Honestly I'd recommend a dedicated TV set-top box.
[1:48] <GenteelBen> A PC just won't be as reliable.
[1:48] <ali1234> it's not for TV, it's a dedicated recorder
[1:48] <ali1234> + playback to LAN
[1:49] <red9> The Pi Zero schematic https://www.raspberrypi.org/documentation/hardware/raspberrypi/schematics/rpi_SCH_ZeroW_1p1_reduced.pdf says it uses PAM2306AYPKE that specify https://www.mouser.se/datasheet/2/115/PAM2306-336770.pdf a maximum of 1.000 A. And Wikipedia says 1.75 W during stress all most likely used at 3.3 V. So there should be 1.000-1.75/3.3 =
[1:49] <ali1234> i'm using a raspi for it right now, but it's not quite fast enough - and mythtv has problems with ARM
[1:49] <red9> 0.470 A @ 3.3V available to be used on the Pi Zero GPIO pin header?
[1:50] <ali1234> also i want to record more channels than can practically be done over USB

[1:50] <red9> ali1234, surverillence?
[1:50] <ali1234> no, just recording TV
[1:51] <BurtyB> red9, it would prob depend on the inductor rating and caps too
[1:53] * genr8___ (~genr8_@unaffiliated/genbtc) Quit (Ping timeout: 264 seconds)
[1:53] <ali1234> i might also put kodi on it for local playback, but that isn't critical

[1:55] <red9> BurtyB, This https://raspberrypise.tumblr.com/post/144555785379/exploring-the-33v-power-rail guy seems to have found that 800 mA can be used at the 3.3 V rail.
[1:56] <red9> Raspberry Pi B+ with buck converter Richtek RT8020. But it seems Pi Zeros all use 1A rated converters.
[1:59] <red9> A question, Are "capture timers" (TIM) available on the BCM chip?
[1:59] <red9> in..
[1:59] * blahdodo (~blahdodo@69.172.190.157) has joined #raspberrypi
[1:59] <ali1234> i don't think so

[2:04] <red9> Anything similar?
[2:04] <ali1234> assuming you mean a counter that starts/stops based on a gpio pin level/interrupt... you'd probably have to do it in software
[2:04] <red9> It seems STM32-ARM does externally triggered DMA transfers by (ab)using TIM capture timers.
[2:04] * uksio (~uksio@p5B12F087.dip0.t-ipconnect.de) has joined #raspberrypi
[2:05] <red9> ali1234, No they work different in this case. But can work as you said.
[2:05] <ali1234> don't know then
[2:05] <ali1234> i'm thinking timer/counter from AVR
[2:05] <ali1234> so i'd just use an AVR or similar, on i2c
[2:06] <red9> Instead, upon a flank edge a register will copy the number from a free running counter to itself. And then it will trigger a IRQ or DMA transfer of one word.
[2:07] <ali1234> k, that's basically a timer counter except for the DMA stuff... AVR doesn't have DMA
[2:07] <ali1234> so... i dunno
[2:07] <red9> So the DMA is setup with perip->memory. But instead of specifying the capture register address. The GPIO port is specified => check mate (against the design) ;)
[2:08] <ali1234> what's it used for?
[2:09] <red9> Actually it's possible to record whenever a signal goes 0->1 and get a timestamp and.. have it transferred with DMA to memory.
[2:09] * ConkyAxis (~ConkyAxis@cpc82865-enfi22-2-0-cust482.20-2.cable.virginm.net) Quit (Ping timeout: 276 seconds)
[2:09] <ali1234> yes that's the intended purpose, but this other thing you just described?
[2:09] <red9> Perfect to record magnetic media recorded in any format whatsoever..
[2:09] <ali1234> DMA from an external clocked ADC maybe?
[2:09] <red9> yes
[2:10] <ali1234> te only thing the Pi has that's remotely similar is the SMI interface
[2:10] <red9> So the STM32 designer envisioned that users shall specify the register of the GPIO port instead of the counter-capture register. The counters (TIM) won't mind being overflowed..
[2:11] <red9> SMI? I2C thing?
[2:11] <ali1234> SMI is shared memory interface, or maybe simple memory interface
[2:11] <ali1234> basically, it is parallel address, data, read, write etc
[2:12] <ali1234> and it's memory mapped so you can DMA from it directly
[2:12] <ali1234> just need to figure out how to trigger the interrupt
[2:12] <red9> interrupt, not DMA request ?
[2:12] <ali1234> well, figure out how to connect the IRQ to the DMA so it works on its own, yes

[2:26] <ali1234> i believe that is every function
[2:26] <ali1234> some are completely undocumented

[2:31] * tdy (~tdy@unaffiliated/tdy) has joined #raspberrypi
[2:32] <red9> I get the urge not too selldom to make a "Pi" that featuresa documented SoC and a documented GPU..
[2:32] <ali1234> you would have to make that SoC first
[2:33] <red9> Oh and with hardwired Ethernet-MAC, with option for dual connections.
[2:33] <ali1234> maybe just get a FPGA?
[2:33] * red_pandabear (~red_panda@2a01:79d:3e81:94bc:3bd1:3cea:540a:6b60) Quit (Remote host closed the connection)
[2:33] <red9> it's an option..
[2:33] <ali1234> https://www.fleasystems.com/fleaFPGA_Ohm.html
[2:33] <ali1234> you missed the kickstarter though
[2:33] <red9> But ASIC uses way less power. And can be clocked faster. So they are different use cases.
[2:34] <ali1234> FPGAs are good for blasting data though :)
[2:34] <red9> yeah!
[2:34] <red9> A/D suck my bits! ;)
[2:34] <dogbert_2> what is everyone using for the initial RPi setup (keyboard, mouse, display), just curious
[2:34] <ali1234> that FPGA can be used as an add of for raspberry pi or stand alone
[2:35] <ali1234> and i have one... but i don't really know how to use it
[2:35] <ebarch> dogbert_2: very few of my Pis have ever had any of those connected to them :P
[2:35] <ebarch> i'm partial to pick up random cheap stuff from goodwill, though
[2:35] <red9> hah.. Amiga 3.x running. Seems that platform will never die;)
[2:36] <dogbert_2> even when setting it up initially?
[2:36] <ebarch> yeah. I just toss the network config and ssh file onto the SD card before I insert it
[2:36] * genr8__ (~genr8_@unaffiliated/genbtc) has joined #raspberrypi
[2:36] <ebarch> works great. even for wifi.
[2:39] * genr8_ (~genr8_@unaffiliated/genbtc) Quit (Ping timeout: 264 seconds)
[2:40] <red9> Now if the FleaFPGA can implement Amiga. Can it implement some kind of rudimentary well supported Unix platform?
[2:41] <red9> Such that one can do A/D and networking with ease.
[2:41] <ali1234> if the minimig has MMU support then yes
[2:41] <ebarch> Just implement your OS in gates, why don't ya?
[2:41] <ali1234> cos then it can run linux
[2:43] * giddles (~giddles@unaffiliated/giddles) has joined #raspberrypi
[2:44] <red9> No MMU in Minimig asfaik.
[2:44] <ball> Ah just bung CP/M on it.
[2:44] <ball> brb
[2:44] <red9> I would implement BSD though :p
[2:45] * govg (~govg@unaffiliated/govg) Quit (Ping timeout: 260 seconds)
[2:45] <ali1234> i think the developer is going to make a high speed ADC add on for it
[2:45] <ball> BSD needs a PMMU too, at least since 3BSD
[2:45] <red9> What makes me wonder the basic premise is "24kLUT elements". It might simply be too few.

[2:47] * Guest12627 (~quassel@tor/regular/SpeedEvil) Quit (Ping timeout: 256 seconds)
[2:47] <ali1234> yes, quite possibly
[2:48] <red9> Amiga 1200 wich has a 68020 with the option of a external MMU can do Unix.
[2:48] <red9> NetBSD is supported for it.
[2:49] <red9> +on it
[2:49] <ali1234> probably would be easier to just make it a USB peripheral
[2:52] <red9> USB is incredible limited.
[2:52] <red9> And messy.

[2:53] * m92 (~m92@93-86-82-211.dynamic.isp.telekom.rs) has joined #raspberrypi
[2:55] <red9> Btw, the SMI interface looks like some ISA-bus alike thing.
[2:55] <red9> It ought to be possible to DMA from it by making the A/D appear at any address.
[2:56] <ali1234> right, exactly
[2:56] * genr8__ (~genr8_@unaffiliated/genbtc) Quit (Ping timeout: 268 seconds)
[2:56] <ali1234> you just need to figure out how to make DMA fire from an external interrupt, which may or may not be possible
[2:58] <ball> red9: We also run the 68020 on mvme68k and sun3. Think both of those have the optional PMMU chip though
[2:59] <ball> 68851, apparently.
[3:00] <red9> Sun(R) used some special MMU design of their own in the beginnign asfaik.
[3:00] <ball> Perhaps they did that on sun2
[3:01] <red9> ali1234, I think wiring the OE to the A/D access pin and ignoring the address pins should do it.
[3:01] <ali1234> quite possibly yes
[3:02] <red9> As for triggering. Shouldn't it be enough to .. "ohh I want to read this 64M x 65536 of data .. DMA kernel call now" ?
[3:02] <ali1234> i guess it would, yes
[3:02] <ali1234> if you get it working i would be extremely interested :)
[3:03] <red9> It should involve using the SMI driver for external "RAM" and wiring the A/D as specified above.
[3:04] <red9> And then dd if=/dev/smi.. bs=65536 of=all_my_adc_data.bin

[3:06] <ali1234> or hook up a logic analyzer and poke registers :)
[3:06] <red9> What modes does the SMI driver support?

[3:32] <red9> Anyway BCM pin 6 - SOE => Output enable (I think..)
[3:32] <ali1234> if you hook up sram it should just be memory mapped. reading/writing should store the values
[3:32] <ali1234> no chip and it will forget the values
[3:32] <ali1234> or just lock up, i dunno
[3:32] <red9> ie NAND --> Pi
[3:33] <red9> pin 7 - SWE => Write enable (Pi --> NAND)
[3:34] * genr8__ (~genr8_@unaffiliated/genbtc) has joined #raspberrypi

[3:37] * genr8_ (~genr8_@unaffiliated/genbtc) Quit (Ping timeout: 268 seconds)

[3:39] <ali1234> whatever offset into the memory window you read/write from is what gets dialed up on the address lines
[3:39] <ali1234> and the data lines are whatever you read/write
[3:39] <red9> Because 64 addresses with 18 bits of data equals to 144 bytes.. ;)
[3:39] <ali1234> yeah but you won't use the address lines
[3:41] <red9> So how is the device accessed?
[3:41] <ali1234> got to look at the driver for that
[3:42] <red9> Not necessarily there. The magic can be in hardware logic. Kind of like finding the driver for DDR dram ..

[4:29] <red9> Just wait for the clock and whenever it goes high with CMD==0 then insert the data?
[4:29] <ali1234> the problem with SDIO will be getting the host controller to just blindly stream data
[4:29] <red9> To grab it.. just trigger a "needs loads.. of data". Catch is control over the clock.

[9:26] <Togra> so, I've discovered I can echo 1 then 0 to one of the led1's brightness file and it turns off the power LED. I always thought this wasn't possible, but since it is.. is there something I can add to config.txt to make this change stick?
[9:26] <Togra> this is with a raspberry pi 3 in particular
[9:27] <Choscura> hmm
[9:28] <Choscura> that is an interesting discovery. I suppose you could do something to reload your custom config.txt to replace the default on boot
[9:28] <Togra> "one of the" can be removed to be easier to read :<
[9:28] <Togra> I've added lines in the past to turn off the activity led, which worked fine. but when I try copying those lines and changing "act" to "pwr", it doesn't have an effect
[9:29] <Choscura> then 'pwr' doesn't seem to be the correct variable name
[9:29] <Choscura> is that 'pwr' something you guessed with, or did you have a reference to that somewhere?
[9:29] * Quatroking (~Quatrokin@507098BE.static.ziggozakelijk.nl) Quit (Read error: Connection reset by peer)
[9:29] <Togra> yeah. I wonder if it's as simple as a different variable, but I'm not sure how I can find what variables are available. I saw it on a guide on how to turn off the LED's, but it was specifically for models not the rpi3
[9:30] <Togra> I think 1, 2 and zero, but it still worked up until the "add these two dtparam lines to config.txt"
[9:30] <Choscura> hmm. Link me what you've got so far.

[11:44] <lyakh> well, I thought #raspbian would be even more inappropriate...
[11:45] <lyakh> anyway, I tried the latest ubuntu core on a Pi 2 B v1.2, and only getting a colour pattern on the display, it isn't booting, and the green LED is blinking 4 short and 4 long pulses repeatedly...
[11:46] <lyakh> another distro on the same Pi, the same card - work fine
[11:46] <gordonDrogon> it's possible that ubuntu doesn't have the right kernel/bootloader code.
[11:46] <mlelstv> probably needs newer firmware ?
[11:46] <gordonDrogon> all ofthe above.
[11:47] <lyakh> firmware?.. oh... cool, didn't think about that... I'll google that - thanks, but any links are appreciated too!
[11:47] <gordonDrogon> well - you can take the firmware (bootcode.bin, start.elf) off a system that works and copy it over.
[11:48] <mfa298> there is some documentation about what the blink patterns mean, butthey're generally about not being able to find the right files on the FAT (/boot) partition
[11:48] * BCMM (~BCMM@unaffiliated/bcmm) has joined #raspberrypi
[11:48] <gordonDrogon> I'd suggest copying the whole of /boot but you also need /lib/modules to go with it.
[11:48] <lyakh> is the firmware loaded dynamically? AFAICS ubuntu core doesn't have any at all
[11:49] <gordonDrogon> the Pi boot process is: GPU -> Load firmware -> load kernel -> turn on ARM.
[11:49] <lyakh> I mean if I mount that SD card on my machine - I don't see those files
[11:49] <mfa298> lyakh: I was meaning this is a reasonable place, it's generic pi stuff which can include non raspian images (although raspbian is probably the most common image used)
[11:49] <mlelstv> lyakh, the files are in the FAT partition, usually mounted as /boot
[11:50] <mfa298> lyakh: if you don't have bootcode.bin, start.elf etc on the FAT partition the Pi can't start things up, those are the firmware files it needs

[11:52] <lyakh> oh, damn, ok, sorry, those files are there
[11:54] * genr8__ (~genr8_@unaffiliated/genbtc) Quit (Ping timeout: 276 seconds)
[11:54] <lyakh> the page with blink error codes has an entry for "4 blinks," I guess that's the one
[11:56] <lyakh> it says "start.elf not launch-able"
[11:56] <lyakh> i.e. the GPU has started, but cannot start the ARM
[11:56] * teepee (~teepee@unaffiliated/teepee) Quit (Ping timeout: 276 seconds)
[11:57] <mfa298> that might mean the files are too old for your hardware

[11:57] * teepee (~teepee@unaffiliated/teepee) has joined #raspberrypi
[11:58] <lyakh> well, it's the current ubuntu core for Pi 2, it shouldn't be too old... SD card - tried two of them...
[11:58] <lyakh> one of them also works in this very Pi with a different distro
[11:59] <mfa298> Is it the same image for the Pi3 as well ? otherwise I wonder if it's worth trying a Pi3 image (as I think the Pi2 v1.2 had the same SoC as the Pi3)
[11:59] <lyakh> really? no, Pi 3 has a different image
[11:59] <lyakh> well, let me try that then...

[12:01] <lyakh> thanks so far, will take a bit, I'll report when done downloading and flashing
[12:02] <mfa298> at some point the SoC on the Pi2 was switched over as the original wasn't needed in large enough numbers to justify a new fab run (most new units sold would be PI3 at that time)

[12:11] <voltagex> hey, it seems like creating /boot/wpa_supplicant.conf is no longer enough to enable wifi on the Pi 3. Also, that rfkill if the wifi country isn't set is nasty.
[12:15] <gordonDrogon> also note that the Pi v2 has 2 ARM variants.
[12:16] <gordonDrogon> I think the 1.2 is the same ARM as the Pi v3 though, but I'd have to check the version numbrs.

[12:18] <lyakh> gordonDrogon: well, yes, that's also what mfa298 has suggested, but so far I haven't got a solution... Really silly if ubuntu core doesn't take that into account... I guess I'll have to try to take some working files from other distros, but that sounds like a recipe for a disaster to me...
[12:18] <gordonDrogon> lyakh, hasn't ubuntu always pushed the edge? If, so then maybe they only care about the ARM that's in the v3 ...
[12:19] <gordonDrogon> but personally, unless you've a pressing need to run ubuntu then I'd stick to Raspbian - most support on the Pi than anything else.

[16:12] <gordonDrogon> red9, yes, but my desktop is not a Pi
[16:12] <ebarch> looks like all my systems have a /etc/os-release file with detailed distro info

[16:22] <Voop> would that be regular raspbian and not raspbian lite?
[16:22] <Voop> or could it still be lite
[16:22] <ebarch> Voop: I think it could still be lite. the difference is really just which packages are installed. so they're nearly identical from a distro standpoint
[16:22] <red9> mlelstv, break the box with BSD ;)
[16:22] <mlelstv> nah. works fine with BSD :)

[16:27] <red9> I had packages install with apt-get that won't show up with dpkg so.. go figure ;)
[16:27] <Voop> i dont really want to wipe the sd card as i have stuff on it that i dont remember how i configured

[16:57] <Voop> yes
[16:57] <Voop> sudo apt-get update && apt-get dist-upgrade
[16:57] <akk> You don't have a sudo on the second one.
[16:58] <akk> The && is interpreted by your local shell, your user
[16:58] <Voop> does it need two?
[16:58] <akk> yes
[16:58] <Voop> til
[16:58] <Voop> works now
[16:58] <akk> you could probably do something like sudo 'sh -c "apt-get update && apt-get dist-upgrade"' to sudo it all in one command
[16:58] <akk> but that's harder to type than just typing sudo twice
[16:59] <Voop> do i need the &&
[16:59] <Voop> i swear ive done this before with one sudo
[16:59] <r3> the && is like an "AND" ... command after && is executed if, and only if, command before && returns an exit status of zero.
[16:59] <akk> You either need &&, or ;, or a newline.
[16:59] <r3> so they are two commands
[16:59] <akk> Personally I generally run them as separate commands. I do sudo apt-get update
[17:00] <akk> then when that finishes, I do up-arrow or ctrl-P, use ctrl-W to erase the update and type upgrade or dist-upgrade.
[17:00] <r3> commands separated by a ; are executed sequentially. The shell waits for each command to terminate in turn. But doing that way will run the 2nd even if the 1st fails.

[17:33] <Habbie> akk, try esc followed by b

[17:35] <r3> hrm, I wonder if I should get the kindle version of that or the paperback
[17:36] <akk> And I should mention I'm trying this on an x86 linux machine, not a pi, but I'd think the bindings would be the same.
[17:36] <akk> In xterm.
[17:36] <Habbie> ok, xterm
[17:36] <Habbie> i bet you can configure xterm to treat one of the alts the right way
[17:36] <Habbie> i've done that in iTerm on macOS - one alt sends these escapes so that they skip words etc.
[17:36] <Habbie> the other one respects the normal macOS tricks for typing special chars
[17:36] <Habbie> you obviously have something similar to the latter on both alts right now
[17:37] <r3> as much as I love my kindle, I have found technical reference to be tricky on it. I seem to be more comfortable with a paper book by my side if I'm looking something up
[17:37] <Habbie> all my references are paper
[17:37] <akk> Ah, .inputrc is the file I was looking for for the custom readline stuff.
[17:37] <Habbie> but if i was a kindle person, unix power tools might work in that form for me
[17:37] <akk> https://unix.stackexchange.com/questions/108098/alt-left-to-skip-words-does-not-work-in-terminal-emulators
[17:37] <akk> Apparently I can set up the alt bindings there.
[17:37] <Habbie> well
[17:38] <Habbie> not if your xterm steals it
[17:38] <Habbie> but you're about to find out :)

[17:51] <akk> Habbie: Yeah, I used csh for many many years so I missed that.
[17:52] <akk> I also bind capslock to be ctrl, because the silly microsoft/ibm-mandated ctrl key position is impossible for me to reach
[17:52] <akk> and I use these various editing characters like 1000000 times a day.
[17:52] <Habbie> i have bound my capslock to some meta as well

[18:48] * user0766543 (~madamewan@185.21.217.79) has joined #raspberrypi
[18:48] <hotpot33> I have tried:
[18:48] <hotpot33> 1. A supercharger (5V, total output 3.1Amp, only RPi connected), says voltage low
[18:49] <hotpot33> I need this for a relatively bigger project and have a few things connected: a Wi-Fi dongle (the embedded Pi shit doesn't connect, says out of range, 0.5Amp)
[18:49] <ShorTie> i like the chromebook 5.25v@3amp
[18:49] <hotpot33> a webcam (0.5amp again)
[18:49] <hotpot33> and N O T H I N G E L S E
[18:49] <ShorTie> and read the topic pleaze
[18:49] <hotpot33> rules?
[18:50] <hotpot33> and that should average around 1.8amp at max load
[18:50] <red9> hotpot33, need low standby/sleep power? or how to supply power for stress loads?
[18:50] <hotpot33> or let's assume it will go upto 2.0amps, I have not connected any GPIO load
[18:50] <hotpot33> second
[18:50] <hotpot33> It doesn't cause problems when I'm doing nothing
[18:50] <hotpot33> but when I run that Google Assistant hotword application and then say ok google
[18:50] <hotpot33> and tail my dmesg
[18:50] <hotpot33> I see it says voltage went low
[18:50] <hotpot33> so I have tried a few things, more.
[18:50] <mfa298> hotpot33: I'd suggest trying the official PSU and see if that solves any power issues. A lot of other things might not manage 5V at the end of the cable when the pi is drawing current
[18:51] <hotpot33> mfa298: The problem is the official PSU's shipping to my country is 3x the actual PSU price
[18:51] * GenteelBen (GenteelBen@cpc111801-lutn14-2-0-cust55.9-3.cable.virginm.net) has joined #raspberrypi
[18:51] <Choscura> again, if you want a psu board, get a cheap battery pack
[18:51] <red9> hotpot33, which country?
[18:51] <hotpot33> 2. I tried a old PSU, by connecting its PS_ON to GND (I read the ATX12V docs)
[18:51] <hotpot33> India
[18:52] <Choscura> those USB battery things to charge phones have decent power boards in them
[18:52] <Choscura> that's what I've seen people, eg, make laptops and tablets out of pi's with
[18:52] <hotpot33> and then connecting one of its Molex connectors' VCC to RPi's Board 2 GPIO and GND to Board 5
[18:52] <hotpot33> then it booted, no issues but it said voltage too low off the bat
[18:52] <Choscura> too low amperage
[18:52] <Choscura> the voltage is the size of the pipe
[18:52] <hotpot33> VCC means the red wires, which should be 5V, I've tested the PSU is working with a fan
[18:53] <Choscura> the amperage is how much water through the pipe (or, electrons, in this case)
[18:53] <mfa298> hotpot33: if you're not going to try the official PSU then alos try some other USB cables. Many USB cables will drop too much voltage (works fine with charging phones but not running the Pi)
[18:53] <hotpot33> Choscura: I know what voltage and amperage is, and the size is a shit analogy
[18:53] <hotpot33> I tried some other cables, about 3 of them
[18:53] <hotpot33> I used one of them with my rpi2 and it caused no problems
[18:53] <Choscura> hotpot33, just establishing baseline. but, whatevers, you need 2 USB chargers to meet/exceed 2.5 amps
[18:54] <Choscura> normal USB is 2 amps
[18:54] <mfa298> I think some people have reported having to try a lot more than three cables to find something suitable (at which point buying the right thing at the start often works out cheaper)
[18:54] <hotpot33> Choscura: A ATX power supply (with max powers as 450W) should work, right?
[18:55] <hotpot33> I wanted to avoid the USB things (USB looks like cancer) and directly wire the ATX's molex 5v and GND to GPIO
[18:55] <stiv> is that 450W on the 5v rail?
[18:55] <Choscura> if it's supplying sufficient amperage, yes. But, if it's supplying a down-regulated standard 2 amps, that's gonna be a problem where you see the lightning bolt.
[18:55] <red9> hotpot33, Use ATX PSU, wire PS_ON to GND. Then use real cables to the 40-pin IDC (GPIO). Be careful to wire the right pins and polarity. It should provide all the juice you need.
[18:55] <hotpot33> but I don't see why that didn't work
[18:55] <mfa298> hotpot33: I think ATX PSU's will often only provide a stable supply if you draw enough current (potentially more than a Pi uses)
[18:55] <hotpot33> stiv: it's max 300W but RPi shouldn't ever exceed 20W, right?
[18:55] <red9> As 'mfa298' said.. too little power use can also be an issue.
[18:56] <hotpot33> red9: I did wire PS_ON to GND and then try out a standard case fan
[18:56] <Choscura> pi shouldn't be going above 5 volts for power pins and 3.7v for the rest
[18:56] <gordonDrogon> A Pi 3+ will barely exceed 10 watts.
[18:56] <hotpot33> a dummy voltage?
[18:56] <hotpot33> a dummy use*
[18:56] <hotpot33> ?
[18:56] <hotpot33> What can I use as a dummy?
[18:56] <Choscura> anything USB?
[18:56] <hotpot33> Wait what
[18:56] <red9> A thin wire. If you measure it first.
[18:56] <hotpot33> ATX doesn't have USB
[18:56] <Choscura> pi is usb
[18:56] <gordonDrogon> You just need 5v for hte Pi. It generates the 3.3 and 1.8v on-board.
[18:56] <Choscura> it runs on 5 volt power, which it steps down internally to 3.7
[18:56] <gordonDrogon> don't try to fee din anything other than 5v.
[18:57] <Choscura> basically.
[18:57] <hotpot33> red9: I did connect RPi's Board pin 2 to PSU's molex 5V and Board pin 5 to molex GND
[18:57] <hotpot33> Well I do supply 5V
[18:57] * Vonter (~Vonter@49.207.60.246) Quit (Ping timeout: 264 seconds)
[18:57] <_Trullo> ok, so a older raspberri pi is working with my hdmi/dvi adapter but not the new model.. I will try a hdmi/dvi cable and see if that works, found cheap ones on ebay.. but it's strange it works on a older model..
[18:57] <red9> Another approach is to get the power from the PC-4-pin-molex used for harddiscs etc.
[18:57] <hotpot33> Molex connectors have 12V and 5V, I wired the 5V
[18:57] <hotpot33> red9: that's what I've been saying, am I lagging?
[18:57] <red9> Then you will already have your dummy load.
[18:57] <hotpot33> Yes.
[18:58] <hotpot33> RPi booted
[18:58] <mfa298> Choscura: if you get 3.7v on your pi something is wrong, the GPIO is 3v3 (fairly standard voltage for logic stuff these days)
[18:58] <hotpot33> but with the power a PSU has, I don't see how it is not the correct voltage
[18:58] <Choscura> eh, I'm probably remembering that wrong, then.
[18:58] <Choscura> mixing up other specs. it's within 3 volts, though.
[18:58] <hotpot33> I think I'll need a dummy load otherwise the PSU won't provide exactly 5V
[18:59] <Choscura> use the USB ports on the computer
[18:59] <gordonDrogon> have you got a multimeter you can check it with?
[18:59] <Choscura> it's possible that this is a dead pi.

[18:59] <red9> Riple voltage may also mess things up.
[18:59] <gordonDrogon> a usb port may not supply enough to power a Pi v3/3+. Zero ought to be fine though.
[19:00] <hotpot33> India's electronics stores are useless and anything I need will be either bought from AliExpress or EBay or Amazon, so shipping is like half the product cost (most of this stuff averages around 100 Rs, and the shipping is mostly flat rate at 50 rs, massive cost efficiency here you see) and 5-12 days
[19:00] <hotpot33> so I need something, erm quick
[19:00] <Choscura> what do you need to do with it?
[19:00] <hotpot33> Choscura: Google Assistant stuff
[19:00] <gordonDrogon> well, if you have a Pc with a spare hard drive power connector, then use that - with the PC turned on.
[19:01] <hotpot33> I'll have to get that wire out of the case, which is a massive pain
[19:01] <gordonDrogon> assuming you have the neccessary tools, etc. to connect it safely into the Pi.
[19:01] <hotpot33> and I don't, I only have this PSU since I replaced this one with a higher wattage one currently sitting on mine
[19:01] <red9> hotpot33, what part of india are you in?
[19:01] <hotpot33> red9: Eastern India, West Bengal
[19:01] <gordonDrogon> well, a spare PSU ought to be OK..
[19:01] <Choscura> kannada?
[19:01] <Choscura> or is that south of you?
[19:01] <hotpot33> nah
[19:01] <JessicaRN> pi3 w/ stretch - having probs configuring iptables. my hw is internet <> wlan0 on pi3 <> iptables <> eth0 on pi3 <> wan port on my router. from the pi I can ping to the net, but from machines connected to the router I get zip
[19:01] <hotpot33> that's too south
[19:02] <hotpot33> anyway
[19:02] <Voop> hotpot33: did anyone mention a powered hub
[19:02] <hotpot33> Voop: powered hub? that stuff is extremely hard to find in India
[19:02] <hotpot33> the powered hub costs like 15$
[19:02] <Habbie> JessicaRN, besides configuring iptables, you most likely also need to enable forwarding via sysctl
[19:02] <hotpot33> I searched for it before
[19:02] <Voop> does india not have amazon.com
[19:02] <Choscura> $15 is the normal price
[19:02] <hotpot33> Yes, Voop, India has amazon.in
[19:02] <hotpot33> Choscura: wait wot
[19:03] <Choscura> an externally powered USB hub? I normally see those around $15
[19:03] <red9> hotpot33, I think you have identified a business.
[19:03] <Voop> they sell powered hubs at the $5 store here

[19:05] <Habbie> JessicaRN, uhm, it's been a while for me
[19:05] <Habbie> JessicaRN, what does your iptables look like?
[19:05] <Voop> just pay $15 for a powered hub and your issue is solved
[19:05] <hotpot33> well, the hub idea is a big nope
[19:05] <hotpot33> at that cost
[19:06] <JessicaRN> Habbie: they are all accept
[19:06] <red9> hotpot33, My point being that other regions might have more access to stuff you need.
[19:06] <hotpot33> I could even buy these USB male and female breakouts
[19:06] <Habbie> JessicaRN, but did you configure NAT/masquerading?
[19:06] <Voop> i had to pay $15 for a usb to rj45 adapter
[19:06] <Habbie> JessicaRN, assuming your setup needs that, it's not entirely clear
[19:06] <JessicaRN> Habbie: iptables -t nat -A POSTROUTING -o wlan0 -j MASQUERADE
[19:06] <hotpot33> Voop: a USB male breakout costs about 2$, and a USB female breakout about 0.5$
[19:06] <Habbie> JessicaRN, what do your IP configs and route table look like?
[19:07] <Voop> then buy that
[19:07] <hotpot33> that's about 2.5$ per port, multiply it by 4, you have 10$
[19:07] <Voop> solder everything to one of those
[19:07] <Voop> and tie another 5v psu in there
[19:07] <JessicaRN> habbie, i'll post it and brb
[19:07] <red9> hotpot33, maybe you can cooperate with someone else locally when ordering overseas?
[19:08] <hotpot33> I just need to get the D+, D- and GND from the RPi, and then hook these to the slaves, but with the VCC and GND (GND will need to be joined with the RPi GND AFAIK) from some other source
[19:08] <hotpot33> 5V PSUs are cancer, I can only find a 5V 3A on Premier Farnell India
[19:09] <hotpot33> I'm reluctant about buying that as all 5V PSUs never work with RPi
[19:09] <Habbie> hotpot33, again please mind your language
[19:09] <gordonDrogon> look for one that says works with the Pi - from Farnell it ought to be good.
[19:10] <Voop> how do they not work with rpi?
[19:10] <hotpot33> red9: well, no, most electronics products I buy are manufactured in China and warehoused in South India
[19:10] <gordonDrogon> if you get the official white Pi one then it should be fine
[19:10] <hotpot33> Habbie: even cancer is banned?
[19:10] <red9> hotpot33, splice an USB cable to separate the Vcc ?
[19:10] <Habbie> hotpot33, using diseases to indicate the low quality of something is not nice, no
[19:10] <hotpot33> red9: I have wasted two precious USB cables trying to separate the VCC and GND
[19:11] <hotpot33> That is a big no-no
[19:11] <Voop> whenever i need a psu for a pi i just buy a 110 to 5v usb wall wart and solder wires to vcc and gnd
[19:11] <Voop> usb cables are for losers
[19:11] <gordonDrogon> best not to do that with those Indian 220 volts ...
[19:11] <stiv> heh
[19:12] <gordonDrogon> the main issue is that USB "chargers" are different from USB power supplies.
[19:12] <gordonDrogon> most devices will tolerate sub-standard chargers, but the Pi needs a good, proper power supply
[19:12] <Voop> ive never had a problem using a charger
[19:12] <JessicaRN> Habbie: https://nofile.io/f/u8hyGPZY1oh/iptables.txt
[19:12] <hotpot33> I also have these power banks that theoretically have 5V 2.4Amp outputs
[19:12] <JessicaRN> Habbie: tyvm
[19:12] <hotpot33> It also has a current meter
[19:12] <hotpot33> I connected them to RPPi
[19:12] <red9> I wonder what the quality of the Indian 220 V is..
[19:13] <Voop> how about this
[19:13] <hotpot33> under load, it said 1.2Amp and then it said low voltage
[19:13] <hotpot33> and then it dropped
[19:13] <hotpot33> it said voltage stabilized about 12s later
[19:13] <gordonDrogon> battery power banks are usually OK, but they're designed for charging, however I've used an Anker unit to power several Pi's in the past.
[19:13] <red9> Btw, India is specified as 230 V 50 Hz.
[19:13] <hotpot33> It didn't even draw 2.4Amp
[19:13] <Voop> hotpot33: power bank > male breakout > rpi?
[19:13] <hotpot33> Is this a defect with my RPi or something

[19:14] <hotpot33> Voop: no, straight from the bank using a standard AmazonBasics MicroUSB cable
[19:14] <hotpot33> gordonDrogon: RPi 3, Model B
[19:14] <gordonDrogon> ok.
[19:14] <Voop> im saying you could try that
[19:14] <red9> not +?
[19:14] <hotpot33> Manufactured in 2015
[19:14] <hotpot33> no
[19:14] <gordonDrogon> it will need a good PSU. So a PC PSU ought to be fine - what was the issue when using that ATX PSU?
[19:14] <red9> hotpot33, you try to power it via USB or IDC-GPIO pins?
[19:15] <hotpot33> red9: USB
[19:15] <red9> Has your Pi ever worked?
[19:15] <red9> ie known to work..
[19:15] <Voop> i have a 5v (well variable from 1v to 24v) 20A psu
[19:15] <hotpot33> I have even tried powering it through my SMPS -> YwRobot Breadboard Power Supply (connected SMPS molex 5v to YwRobot 5v Rail and GND to GND) then connected its USB female to the RPi male
[19:16] <red9> I read that the 5V rail input has tolerance of +/- 0.25 V.
[19:16] <hotpot33> red9: it does everything correctly without causing problems when not connected to a webcam and wifi dongle
[19:16] <hotpot33> no low voltages and stuff

[19:18] <hotpot33> AmazonBasics is reliable and I've seen that cable charge my phone at 1.8amp from the power bank
[19:18] <Voop> well the pi3 needs like 2.5a by itself
[19:19] <gordonDrogon> Voop, it doesn't quite need that.
[19:19] <zleap> yeah
[19:19] <hotpot33> I'm just surprised the RPi didn't even pull 2.4Amp (max, even if that's just marketing talk, atleast 2amp) from the powerbank under load
[19:19] * Haxxa (~Harrison@180-150-30-18.NBN.mel.aussiebb.net) Quit (Ping timeout: 265 seconds)
[19:19] <hotpot33> if it hit the max and said low voltage, I'd be satisfied and replace my PSU
[19:19] <hotpot33> but it didn't hit the max rating from my power bank ever seen (1.8Amp) as well
[19:19] <red9> The Pi might utilize peak loads that normal multimeters atre just to slow to catch.
[19:20] <hotpot33> well webcam-based video processing is not a peak load
[19:20] <hotpot33> it is a sustained load, amirite?
[19:20] <gordonDrogon> it's a complex subject the whole Pi PSU thing. Over the years we've found that various cheap PSUs are not up to it. The other thing is the quality, or lack of quality of the copper from the PSU to the connector. Then the connector. Then there are peak loads - at power on time, and during SD cards writes.
[19:20] <gordonDrogon> it all adds up to the need for a good quality PSU and cabling.
[19:21] <Choscura> are you guys saying "PSU" to refer to the plug that goes into the wall?
[19:21] <gordonDrogon> yes.
[19:21] <mfa298> Voop: but if you're using a pi zero then a) it uses a lot less power than the Pi3, and b) dosen't have and lower power indication so you wouldn't know if the voltage is dropping too low occasionally
[19:21] <gordonDrogon> PSU - wall wart, etc.
[19:21] <Choscura> yeah, the cheap ones, you *can* use, in parallel, with 2 2-amp ones or 3 1-amp ones
[19:21] <Choscura> that's the difference between them
[19:21] <Choscura> you need enough cumulative amperage
[19:21] <gordonDrogon> best to just get a good one in the first place.

[19:22] <gordonDrogon> although if hotpot33 has an ATX PSU, then that should work - assuming it can be cabled to the Pi safely.
[19:22] <Voop> still less power than the 3 or 3+
[19:22] <hotpot33> I don't get it, why did my RPi not draw 1.8Amp (the max I've seen from my proven power bank) when I did a sustained live streaming from power bank?
[19:22] <Choscura> or, use a 2 amp and get a powered USB hub additionally, because that will make up the difference

[19:22] <hotpot33> gordonDrogon: I did try that, but RPi just said right off the bat low voltage (on boot, lol)
[19:22] <Choscura> hotpot33, that may be the maximum output of the battery at peak charge
[19:22] <mlelstv> the rpi itself barely needs 0.4A under load
[19:23] <Choscura> aka, it may not be enough

[19:23] <hotpot33> I've read that it'll not provide stable voltage if you don't give it a big enough load
[19:23] <gordonDrogon> The Pi doesn't know if it's being powered via battery or mains.
[19:23] <hotpot33> gordonDrogon: I know it's a low voltage warning
[19:23] <Choscura> what, the lightning bolt thing?

[19:23] <hotpot33> Choscura: I saw it on dmesg -Hw
[19:24] <mfa298> Choscura: putting PSUs in parallel can also cause a lot of additional issues - if one voltage is slightly above the others you might end up trying to draw more current from that one and damage it - or the slighlty higher voltage might damage the other PSUs.

[19:28] <gordonDrogon> Choscura, no, you can't say that.
[19:28] <hotpot33> If it says under-voltage again with the wires supplied with the 3A PSU, I'm legitimately going to scrap my RPi and throw it in the dustbin
[19:28] <Voop> im also still waiting on an answer to your question, why isnt the pi pulling the amperage you know the supply can provide
[19:28] <hotpot33> https://screenshotscdn.firefoxusercontent.com/images/be5e57ba-8d69-456c-ba40-fc306b5d2184.png

[19:29] <hotpot33> looks like it has the wires
[19:29] <hotpot33> I still think RPi and broadcom stuff in general is a mystery that none can solve
[19:29] <JessicaRN> Habbie: https://nofile.io/f/TGC144b8B3H/iptables.txt
[19:29] <Lartza> Voop, What do you mean not pulling the amperage?
[19:29] <gordonDrogon> The Pi3 has a 2.5 amp polyfuse on the input too, so that'll trip if you plug in anything that takes it over that limit.
[19:29] <JessicaRN> Habbie: its at the bottom
[19:30] <Voop> Lartza: hotpot33's supply is known to be able to provide 1.8A
[19:30] <hotpot33> I've used my powerbank to charge my phone which only takes 1.8A at max
[19:30] <Voop> Lartza: but the pi is not even pulling 1.8A despite giving low power warnings
[19:30] <hotpot33> it sustained that load
[19:30] <hotpot33> ^
[19:30] <Habbie> JessicaRN, it's not loading for me, can you try pastebin.com?
[19:30] <JessicaRN> sure
[19:30] <Lartza> Voop, Supply or charger?
[19:30] <hotpot33> Lartza: it's a power bank
[19:31] <Voop> i believe its a power bank
[19:31] <Lartza> So then, it's not guaranteed to stay at 5A
[19:31] <Lartza> *5V
[19:31] <Lartza> And the pi is not a battery

[19:34] <Voop> how many amps tho
[19:35] <hotpot33> this should work afaik but this takes from microusb but doesn't provide microusb, which will require a female breakout and yet another wire (hopefully it can carry 3A, otherwise I'll facepalm) to the RPi

[19:37] <mfa298> JessicaRN: I've not followed all the conversation you had with Habbie, but in trying to debug network routing/nat issues it can often be useful to check it a stage at a time (e.g. try a PC plugged direct into the Pi first before adding extra routers in the middle). Looking at packet captures (tcpdump and/or wireshark) can also help to see if packets are getting translated properly
[19:37] <Voop> would be nice to have one with a pot on it

[19:42] <hotpot33> Voop: looks good but I'll need a multimeter to measure how much volts it's emitting so I can adjust it to 5v ?
[19:43] <mfa298> JessicaRN: the point about taking it out of the equation is it means fewer potential places causing problems. If the PC->Pi->Internet works then you know it's the router at fault, if the PC->Pi->internet doesn't work then you're only dealing with getting the Pi part working without worrying about whether the router is doing the right thing.

[19:49] <red9> hotpot33, Do you have to pay any special customs or taxes on your Chinese imports?
[19:49] <hotpot33> yes, I technically should
[19:49] <JessicaRN> ok, it didn't work. I used both a straight thru cable and a crossover just in case that made a difference. I could ssh into the RPi3 but I couldn't ping beyond it
[19:50] <JessicaRN> habb
[19:50] <JessicaRN> Habbie:
[19:50] <hotpot33> but most of these Chinese (erm, insert some stupid expletive here) make everything a gift so I don't pay any customs
[19:50] <Lartza> That doesn't work...
[19:50] <Voop> the chinese website i use declares the package contents as worth one dollar
[19:50] <hotpot33> if it were not a gift, it would work
[19:50] <Lartza> Customs aren't that stupid
[19:50] <Habbie> JessicaRN, if you could ssh, the cable was not the problem
[19:50] <hotpot33> Lartza: apparently so
[19:50] <red9> hotpot33, Welcome to the club :-)
[19:50] <Lartza> Marking as 1 dollar doesn't work either
[19:50] <Lartza> There are just so many china packages they can't handle them all
[19:51] <Lartza> Customs doesn't trust declarations like that, they aren't idiots
[19:51] <JessicaRN> Habbie: yeah, I get that. So I have connection to the pi but not through the pi
[19:51] <Voop> im sure they arent retarded
[19:51] <red9> Lartza, which country are you reffering to?
[19:51] <Voop> but it goes through
[19:51] <Lartza> Most
[19:51] <Habbie> JessicaRN, next step, on the pi, tcpdump the packets coming from the pc, and packets going out of the pi; see if the pi is doing the right thing
[19:51] <hotpot33> Lartza: idk but that stuff works for me
[19:52] <JessicaRN> Habbie: ok, but i don't know how to do that
[19:52] <Lartza> hotpot33, Have you actually tried ordering something that is marked not as gift and over the amount and it got caught?
[19:52] <Habbie> JessicaRN, read up on tcpdump or wireshark or tshark
[19:52] <Lartza> From the same origin country
[19:52] <Habbie> JessicaRN, run one on eth0, run one on wlan0
[19:52] <hotpot33> apparently Indian customs are one of the most corrupted and (again insert some expletive here, mods) people on earth

[19:52] <hotpot33> they ship the products and they can put arbitrary stuff there
[19:52] <Voop> making me think of a swear word is the same as saying the word
[19:52] <Voop> where the mods at
[19:53] <JessicaRN> Habbie: k. bbiab
[19:53] <hotpot33> they can make it a gift, they can make it a 1000$ extremely rare product that I have to pay 250$ for
[19:53] <hotpot33> I'll make my hexchat change all swear words into (Insert some stupid swear word here)
[19:53] <Lartza> Also in the context of multimeters https://www.amazon.in/HITSAN-Digital-Multimeter-Backlight-Current/dp/B078Q7RKMZ
[19:54] <Lartza> That's the cheapest cheap better than 10 buck one I can find
[19:54] <hotpot33> good god that isn't Prime (probably a shady dealer)
[19:54] <mfa298> JessicaRN: as a simple option for tcpdump open two sessions to the pi and use something like `sudo tcmpdump -nnv -i eth0` on one and a similar one for wlan0 on the other. If you ping from the PC to the internet you should see packets appear on both tcpdumps
[19:54] <hotpot33> I don't buy anything but Prime
[19:54] <Voop> thats like a million ruples
[19:54] <hotpot33> if I buy something out of Prime either EBay or AE
[19:55] <hotpot33> the seller name 'Nothing Lyk U' is probably looking more shady than anything else in the world
[19:55] <Lartza> That multimeter should cost around 24USD so it's a bit expensive in amazon.in
[19:55] <hotpot33> plus 2-4 weeks shipping

[19:55] <lyakh> FWIW: problem fixed. after replacing the firmware, I had to first boot with no ethernet connected, only plug it in later...
[19:55] <hotpot33> Lartza: that seller is probably a reshipper with stuff in the Europe/US
[19:55] <hotpot33> they buy from EU/US/RU then add 5$ and shipping
[19:55] <hotpot33> and send it here
[19:56] <Lartza> Maybe, but any of the models I looked for were more expensive than that even though they should have been 20-30USD too so :S
[19:56] <hotpot33> that's why no Prime cuz Amazon won't fulfill that
[19:56] <Lartza> So maybe amazon.in just sucks for multimeters :S

[20:01] <hotpot33> this is the first hit
[20:02] <hotpot33> I hardly need a multimeter and when I check for amp loads and voltages I just borrow my friend's
[20:02] <Voop> Lartza: 10 buck meters are fine for noobstuff
[20:02] <Voop> in my opinion
[20:02] <Lartza> Depends on what that noob happens to do :P But yes they can be
[20:02] <Lartza> Don't stick it into mains and don't expect accuracy and don't expect microcurrents or other extreme ranges and you are good
[20:03] <hotpot33> I don't see a use for the multimeters

[20:03] <hotpot33> Lartza: don't expect accuracy? wat?
[20:03] <Lartza> Yes?

[20:06] <Habbie> JessicaRN, the ISP or the IP?

[20:06] <Habbie> ok
[20:06] <Habbie> how about 8.8.8.8?

[20:08] <mfa298> hotpot33: for a cheap DMM whilst it's display might show 4 figures, it might not actually be accurate to that level (so if you got 4.999V on the display the real voltage might be 4.7V)
[20:09] <hotpot33> mfa298: so 5v can be potentially 4.8v?
[20:09] <hotpot33> that's misleading af, that's close to the RPi 5v +- 0.25
[20:09] <hotpot33> ah spez again
[20:10] <mfa298> if you bought a $200 fluke then it will likely be a lot more accurate (and you can potentially pay to get it properly calibrated)
[20:10] <hotpot33> this one is a 9999 counts
[20:10] <hotpot33> mfa298: at 200$, I'd buy a new Intel embedded Atom SOC and ditch RPi

[20:12] <hotpot33> wt(mods), ZT301 is cheaper than the one I had in mind
[20:12] <Lartza> It does mean accuracy in one place but the problem can sometimes be in the circuitry :)
[20:13] <hotpot33> erm I can't judge all these AN800{8-9} and ZT30{1-2}
[20:13] <Lartza> :)
[20:13] <hotpot33> can you tell me which one is the best for my needs
[20:13] <Lartza> You should be fine with the cheapest if you wish to save

[20:14] <Lartza> Since you are already getting a much better meter than the 8 dollar one
[20:14] <hotpot33> I just need a voltage measurement/amp measurement/some other stuff I don't realize I need/ with max accuracy while not paying enough money to buy an Atom SOC
[20:14] <hotpot33> hmm
[20:14] <hotpot33> k
[20:15] <hotpot33> https://waa.ai/zbSU
[20:15] <hotpot33> is this one a hybrid
[20:15] <hotpot33> cuz this one has both ZT301 and ZT302
[20:15] <hotpot33> and no that isn't a rickrolling
[20:15] <JessicaRN_> mfa298: Habbie: I could not ping 8.8.8.8. My dumps are here: https://pastebin.com/JxBDf2iX
[20:16] <hotpot33> Lartza,
[20:16] <mfa298> hotpot33: you need to look up the devices manual/datasheet which might tell you what the measurement accuracy is. A quick look suggestes between 0.1% and 5% on one meter depending on what's being measured and what range.
[20:16] <JessicaRN_> mfa298: Habbie: both dumps in one file. ---------------------------------------- seperates the two
[20:16] <Habbie> JessicaRN_, sorry, i have to go - good luck!
[20:16] <Lartza> hotpot33, No you should somehow get to choose one
[20:16] <JessicaRN_> Habbie: ty
[20:16] <hotpot33> I assume more counts == more what ?
[20:16] <Lartza> "Accuracy"
[20:16] <hotpot33> I'm getting the cheapest 9999 counts
[20:17] <hotpot33> and pray to Jesus that I don't get rekt
[20:17] <mfa298> so for 5V at 1% the voltage could be between 4.95 and 4.05v which might be good enough for most hobbiest use but isn't good enough for other things.
[20:17] <red9> Don't forget the safety quality when buying multimeters. Is good to have for the mains handling ranges.
[20:18] <hotpot33> mfa298: 1% of 5 is 0.20
[20:18] <Lartza> red9, Forget that if not paying for an expensive brand one
[20:18] <Lartza> hotpot33, The problem with all the 9999 count ones I listed are the A and mA ranges are on the same input hole
[20:18] <Lartza> So they might not be as good at measuring amperage as the zt301
[20:19] <hotpot33> I hardly work with mains, when I work with mains I normally do stuff with relays
[20:19] <Lartza> but ymmv unfortunately so it's hard to say
[20:19] <Lartza> never plug a 20USD meter to mains
[20:19] <Lartza> The ratings are a lie 99% of the time
[20:19] <Lartza> 100% of the time on a 4USD meter
[20:19] <JessicaRN_> mfa298: is that you wanted?

[20:20] <mfa298> JessicaRN_: there's a lot of stuff in there which makes it hard to work out what's going where, it might be worth adding `icmp` onto the end of those tcpdump commands so it filters out to only pings.

[20:37] <Lartza> hotpot33, Uh?
[20:38] <gordonDrogon> you're squabbling over minutia...
[20:38] <hotpot33> you said you have to adjust it beforehand
[20:38] <Lartza> multimeters have ranges, to measure resistance between X and Y
[20:38] <hotpot33> ah
[20:38] <hotpot33> so you need to know you are adjusting between 0.X and 0.X+1
[20:38] <JessicaRN> did mfa298 take off?
[20:38] <Lartza> autoranging means it'll just select it automatically, once you select resistance and stick it in

[20:40] <Lartza> red9, Exactly, thus save your life and don't do mains
[20:40] <JessicaRN> mfa298: what did i do incorrectly?
[20:41] <mfa298> JessicaRN: the ICMP redirects on the eth0 side are also interesting, they look to be tellign the client machine to talk direct to something it can't talk direct to.
[20:42] <JessicaRN> mfa298: crud. this has been two days of screwing with this (^#*&%#% thing

[20:46] <mfa298> JessicaRN: looking back at the routing table you posted earlier I think the default route might be giving some issues. it looks to be for 192.168.1.254 (probably right) but on eth0 (probably wrong)
[20:46] <JessicaRN> mfa298: is it possible to configure dnsmasq to act as a firewall? would that be an easier solution?
[20:46] <red9> Lartza, Don't do mains with Chinese brands :p
[20:47] <JessicaRN> mfa298: ok, so what suggestions do you have?
[20:47] <Lartza> red9, Right, and then you are left with namebrands unfortunately and those are expensive, but yeah
[20:47] <mfa298> JessicaRN: this looks to be at the routing level rather than NAT. (and I've never used dnsmasq so I'm noy sure what it can do)
[20:47] <Lartza> Also I am sure there is at least one chinese multimeter manufacturer out there that does actual expensive mains rated meters
[20:48] <JessicaRN> mfa298: ok, so, what should I try next?
[20:48] <Lartza> It's not like all of china is cheap and no good
[20:48] <red9> Lartza, sure, the question is how do you know which one it is ..
[20:49] <Lartza> Do I really have to look? :P
[20:49] <red9> Unless it's manufactured in China and say Fluke have quality inspector on site to stamp OK.
[20:49] <mfa298> JessicaRN: probably check what you're routing tables look like now (in case they changed between the various other tables). I'd also suggest sketching out how things are setup as that can often help in working things out.

[20:50] <mfa298> possibly also look at where the default route is set and check there's not a silly mistake in there (you shouldn't need to specify which interface)
[20:50] <Lartza> red9, My point was really that Fluke could be a chinese company and do good multimeters, it's all about the company not the country
[20:51] <Lartza> All of the good companies seem to be in taiwan, korea etc though... :P
[20:51] <Lartza> If not in germany or US
[20:51] <red9> It's about culture and work ethic. Which local culture usually influence.
[20:52] <mfa298> JessicaRN: it might also be worth checking ping 8.8.8.8 from the pi works.
[20:53] <JessicaRN> mfa298: https://pastebin.com/rkXN0K60
[20:53] <JessicaRN> these are my 3 config files I've messed with
[20:53] <JessicaRN> It was a bear to get the pi to see both the eth0 and the wlan0
[20:53] <Lartza> That of course plays a part, but take phones for instance and Huawei is chinese and does just well
[20:54] <Lartza> or Lenovo
[20:54] <Lartza> and huawei doesn't of course do phones only, even cutting edge stuff like 5G

[21:09] <Lartza> Yeah /etc/network/interfaces isn't used if you are on stock stretch
[21:09] <Lartza> Since it now ships with dhcpcd
[21:09] <Lartza> wheezy probably does still use it

[21:10] <mfa298> hopefully very few people are using wheezy these days, that's not been supported by RPF for a few years now (we had Jessie in the middle which used dhcpcd)
[21:11] <Lartza> I just remember JessicaRN mentioning a wheezy rpi2 :S
[21:11] <JessicaRN> I read about that, but for the life of me I couldn't get it to work at all w/o using interfaces
[21:11] <mfa298> I think the later wheezy builds also had dhcpcd but that was a long time ago (in Pi time at least)
[21:12] <JessicaRN> ok, i got rid of the gateway in interfaces
[21:12] <JessicaRN> rebooting now
[21:13] <mfa298> JessicaRN: possibly one option that might be worth looking at is telling dhcpcd.conf to ignore eth0 and then use /e/n/interfaces to configure that. but leave dhcpcd dealing with wlan0 (and dont have references to that in /e/n/interfaces)
[21:14] <JessicaRN> ok, but first, after removing the gateway I can now ping both google and 8.8.8.8 from the pi. Lemme disconnect from IRC and try it from the PC

[21:21] <CarlFK> JessicaRN: "specified port" needs more.. um.. context? or something. What do you want?
[21:22] <mfa298> JessicaRN: I tend to add some log rules and then add rules to cover the traffic I want/dont want based on what gets logged.
[21:22] <JessicaRN> CarlFK: so, the wlan0 port is the outside on this config. Can I deny login from that port?
[21:23] <JessicaRN> mfa298: any chance you have a sample of an effective table?
[21:23] <mfa298> For SSH you can use the iptables INPUT rule to limit who can talk to it - I usually also move it onto a different high port (particularly if its open to the world)
[21:23] <Habbie> you can also tell sshd to only bind to specific IPs

[21:24] <CarlFK> JessicaRN: but you don't want the outside, so that doesn't matter. What about the inside port?
[21:25] <JessicaRN> I need to be able to login from the inside, just not the outside
[21:25] <CarlFK> is the inside a static IP?

[23:45] <tempate> Hello. I'm trying to program an EEPROM (28C16A) using my RPi 2. I've found a similar implementation to what I'm looking online but it doesn't seem to work. It's the first time I do anything with the RPi so I'm kinda lost. Can someone please help me out? Here is the code: https://bpaste.net/show/3925850edb9b
[23:47] <tempate> What I doubt the most is not the code but rather the way in which I should write to the pi
[23:48] <tempate> r/pi/eeprom/
[23:49] <CarlFK> tempate: you need to give details about "doesn't seem to work"
[23:50] <tempate> When I try to read the values (on a manually built breadboard) it returns all 1s instead of what it's supposed to
[23:51] <CarlFK> do you have rom you can use to see if it can read data?
[23:52] <Rickta59> don't you have to erase it before you write it?
[23:53] <tempate> CarlFK: Not really. I've programmed some EEPROMs manually but I was hoping to accelerate the process with the pi.

[23:55] <tempate> Rickta59: yes, the thing is that the erasing code is fairly similar
[23:55] <tempate> I'm not. Is that a thing?
[23:56] <Voop> 50 minutes into updating the unix x86
[23:56] <Rickta59> have you looked at any arduino code that does this type of thing?
