12:11 AM rue_: McDonaldsWiFi,
12:14 AM rue_: my final answer is: 74138 for decoding the /CS /RD /WR, a 74ls365 for an input buffer, and a 74ls174 for a output buffer. it gives you 6 inputs ad 6outputs, you can do multiple spi channels with it, because the avr has hardware spi, it can go as fast as the z80 can shift serial
12:15 AM rue_: nuxil, YOUR NOT GIVING THAT CODE TO THE MILITARY RIGHT!?
12:15 AM * rue_ stares at nuxil
12:15 AM nuxil: heh. its safe with me :D
12:16 AM rue_: ok...
12:16 AM nuxil: i'll take good care of it :)
12:19 AM rue_: so I melted some plastic down in the reflow oven yesterday
12:19 AM rue_: the temperature control sucks, but the rest works great
12:19 AM rue_: my circuit for debouncing those chineese encoder knobs worked good
12:19 AM nuxil: hack the temp control :)
12:19 AM rue_: oooh, I forgot my capacaitors at work
12:19 AM rue_: Emil, I still want to know what the https is protecting
12:19 AM nuxil: 1st i liked rotory encoders. but then i discoverd how easy it is to make keypads using r3r network (dac) so in theory you can do like 1024 (-2 ) buttons with 1 wire
12:20 AM nuxil: *r2r
12:20 AM rue_: my best guess is its to prevent my isp from using a man-in-the-middle attack to insert ads
12:20 AM rue_: you cant just replace knobs with buttons...
12:21 AM nuxil: well not 1 button, but 2 can
12:21 AM rue_: no
12:21 AM rue_: thats like giving up a car and using the bus
12:21 AM rue_: its not the same
12:21 AM rue_: PEOPLE REALLY DONT LIKE YOU TRYING TO TRANSPORT 20' PEICES OF PIPE ON THE BUS
12:22 AM rue_: "oops, sorry, oops, no, sorry about that, oh, did, sorry"
12:22 AM nuxil: i didnt say it be a good splution.
12:23 AM nuxil: *solution. but its possile since a rot enc is just left/right. and this can be done with buttons.
12:23 AM rue_: its not tho, its speed
12:23 AM rue_: if you used force sensitive buttons, then ok
12:23 AM rue_: otherwise NO
12:23 AM rue_: BUT
12:23 AM nuxil: with buttons you can make software solution. press, hold, release.
12:24 AM rue_: you can replace an encoder with a dc motor }:]
12:24 AM nuxil: yes i know :D
12:24 AM rue_: no less, one from a cdrom
12:24 AM rue_: IT WORKED GREAT
12:24 AM nuxil: i saw that video great scott made
12:25 AM nuxil: using a hdd motor
12:25 AM rue_: no, not a brushless, a dc motor
12:25 AM rue_: an actual dc spindle motor from a cdrom
12:25 AM rue_: brushed
12:26 AM rue_: you see, they generate a diffrential voltage depending on the speed you rotate them at
12:26 AM nuxil: yea.
12:26 AM nuxil: spinn it fast enuf and fry your chip :p
12:26 AM rue_: if you put a voltage divider across them, then the middle voltage is always the same, nomatter which direction or speed your going
12:27 AM rue_: so, if you set that to 2.5V using a votlage divider, then one side of the motor goes up and the other side goes down
12:27 AM rue_: you put that input two adc channels
12:27 AM nuxil: i think these hacks are cool, but rather unpractcal to use irl
12:27 AM rue_: it worked
12:27 AM rue_: you put it into two adc channels, and calc the difference
12:27 AM rue_: then integrate it for position
12:28 AM rue_: I'v not seen anyone else do it that way
12:28 AM nuxil: nor have i
12:28 AM rue_: you get good resolution and the whole 5V scale
12:28 AM rue_: ....can I draw it for you?
12:29 AM rue_: its just too bad there isn't a way to hardware integrate it
12:29 AM nuxil: no need. dont think i ever have use for it.
12:30 AM rue_: human interface
12:30 AM rue_: where the exact position dosn't really matter
12:30 AM rue_: I was playing with using steppers
12:30 AM rue_: but it got stupid
12:30 AM rue_: really stupid
12:31 AM nuxil: hehe.
12:31 AM rue_: the circuit was picking up whisper quiet noises from across the room as signal noise
12:31 AM nuxil: aww.
12:31 AM rue_: it was only cause I had the scope on it that I realized it was changing to the music
12:31 AM nuxil: lol
12:32 AM nuxil: it was dancing to your local radio station ?
12:32 AM rue_: heh no
12:32 AM rue_: but you could clearly see the trace move to someones voice speaking softly 30' away
12:33 AM nuxil: you mean. it picked up acustic sounds ?
12:33 AM rue_: it was a WTF moment
12:33 AM rue_: yea,
12:33 AM nuxil: wtf
12:33 AM rue_: soft talking from 30'
12:33 AM nuxil: how is that possible
12:33 AM rue_: I didn't know
12:33 AM rue_: I was annoyed, It was not working out as a position encoder
12:34 AM rue_: I might regret not having saved that circuit
12:34 AM nuxil: did you have some piezo element or something else in your circuet ?
12:35 AM rue_: no, the stepper motor was picking it up
12:35 AM nuxil: thats a big wtf
12:35 AM rue_: we did a test, with a peice of pcb clipped to the shaft it pickup up the noises better
12:35 AM rue_: 1x2" peice of fr4
12:36 AM rue_: the audio was distorted, dont get me wrong, but it was stupidly sensitive
12:39 AM nuxil: sounds verry strange.
12:40 AM nuxil: i dont get it. a stepper should not pickup voices from 30feet away.
12:41 AM nuxil: i tried google. but i didnt get any wiser.
12:42 AM nuxil: you dicovered a discovered a anomaly
12:42 AM nuxil: err..
12:42 AM nuxil: cant type
12:43 AM Casper: now, you understand why it is impossible to be 100% sure that a circuit do not spy on you
12:43 AM Casper: also, there is some multi-layers ceramic capacitor that is very sensitive to vibration
12:43 AM Casper: they most likelly can be used as crude mic
12:44 AM nuxil: there must be some parasit phenomen that is affecting the circuet
12:46 AM nuxil: Casper, indeed. multilayer cer cap can acts as crude mics. but i dount it will pic up any vibration from a voice wispering 30feet away
12:46 AM nuxil: *doubt
12:47 AM Casper: except if you actually make a special one
12:47 AM Casper: nsa style
12:47 AM rue_: it wasnt what i wanted
12:47 AM rue_: i was trying to make a sensitive tey robust coil pickup
12:48 AM rue_: so that you could turn the stepper slowly and still get counts
12:48 AM rue_: i think i was playing with self biasing when it started doing that
12:49 AM rue_: when we worked out sound was the source of the electrical noise, I shoved it all into the corner and rethought the whole goal
12:49 AM rue_: but it wasn't till the drive to work the next day that I came up with the dc motor idea
12:50 AM rue_: than at lunch I reworked it onto that balanced thing
12:50 AM rue_: which gives the most gain and range for the least components
12:51 AM rue_: I bought some diff video amps to try later to pick up the gain even more
12:51 AM rue_: you have to ignore a few adc counts, but from what I can tell its adc noise, not circuit noise
12:52 AM rue_: it would be more sensitive if ya used the 1.1V vref
12:52 AM rue_: didn't try that
12:52 AM rue_: ANYONE WANT TO SEE CODE NOW?
12:53 AM rue_: rue
12:53 AM rue_: yea?
12:53 AM rue_: they all left
12:53 AM rue_: left as in not right?
12:53 AM rue_: no as in gone
12:53 AM rue_: awe
12:54 AM rue_: gnight
12:54 AM rue_: gngiht
12:54 AM * Casper throws a snowball on rue_
01:00 AM rue_: crap, I cant put the server rack where I wanted in the living room, the cieling fan is in the way
01:00 AM rue_: oh wait, if I saw off half of one of the blades I might be ok
01:03 AM Haohmaru: chainsaw massacre
01:32 AM Emil: rue_: it's protecting my sanity from your idiocy
01:33 AM -!- #avr mode set to +o by ChanServ
01:33 AM -!- #avr mode set to +b by rue_
01:34 AM z999: hello how do i know if my script worked in atmel?
01:34 AM z999: i have c h z flags. if it is red does that mean script is not working?
01:35 AM rue_: script?
01:38 AM nuxil: what ?
01:39 AM z999: coding
01:39 AM nuxil: you make no sense. you need to explain more.
01:39 AM z999: i am talking about atmel studio 7
01:40 AM z999: i am trying to do asm coding
01:40 AM z999: kline told me to try here for help
01:40 AM nuxil: asm is not scripting :p
01:40 AM z999: sorry i am very new
01:40 AM z999: i wrote a little code for class
01:40 AM nuxil: also. if what is red ?
01:40 AM z999: what is that called?
01:41 AM z999: nuxil, i have to restart my computer. brb ok? ill explan in afew minutes
01:42 AM nuxil: i dont know if i can help :p
01:42 AM nuxil: i do not use atmel studio.
01:42 AM nuxil: notepad++ and makefiles ftw :D
01:48 AM z999: hello nuxil
01:48 AM z999: my firefox was crashing and had to restart
01:48 AM nuxil: im not sure if you got my message. i had part/join messages hidden so i didnt see you leave.
01:48 AM z999: pc
01:48 AM z999: please repost
01:49 AM nuxil: but as i said. i dont think i can help .i dont use atmel studio. im a notepad++ & makefile dude.
01:49 AM z999: oh too bad
01:50 AM z999: rue_ do you use atmel studio 7?
01:51 AM nuxil: but anyway. your problem. it should not matter what you use.
01:51 AM rue_: hah no, I use nedit and a make file
01:51 AM rue_: make; make install
01:51 AM nuxil: ^^
01:51 AM z999: do you know if there is support for atmel studio 7?
01:52 AM nuxil: but if its just code related. ask.
01:52 AM z999: i have to do 5 activites and wondering if the coding is correct
01:52 AM z999: right now i am on activity 1
01:52 AM z999: do i paste the code in pastebin so you can see?
01:53 AM nuxil: yes use pastebin
01:53 AM z999: ok one moment
01:53 AM nuxil: rue_, luvs asm if thats what your doing :p
01:53 AM * nuxil hides
01:53 AM z999: ok be patient with me i am at the very beginning stages of asm. i am still reading the book.
01:53 AM z999: this is for my class
01:53 AM z999: ok?
01:53 AM z999: brb
01:54 AM rue_: how about the real book
01:54 AM Emil: rue_: what was that ip range btw?
01:54 AM nuxil: polprog, give him your asm tut/docs :)
01:54 AM rue_: Emil, prolly comcast
01:54 AM Emil: why'd ya ban it? :D
01:54 AM rue_: rucas had a bot comming
01:54 AM Emil: ah
01:54 AM rue_: it might help, I dont know
01:55 AM nuxil: z999, http://polprog.net/blog/asm/
01:55 AM Emil: z999: bro, why asm?
01:55 AM Emil: also rue had a good asm tutorial somewhere
01:55 AM Emil: have you coded in c before?
01:56 AM Emil: you might want to also check out https://emil.fi/avr for a quick and dirty introduction
01:56 AM z999: emil, i took c two years ago. i found it hard and i haven't used it after the class finished
01:56 AM Emil: (the https protects super sensitive stuff, don't ask)
01:56 AM z999: i remember some things
01:56 AM rue_: you cant check it out if you dont ahve atleast 128 bit encryption support on your browser
01:56 AM z999: nuxil thanks
01:56 AM nuxil: yea. why not use C.
01:56 AM Emil: rue_: you, too, have 128 bit encryption support
01:56 AM rue_: no
01:56 AM z999: emil, the class is microprocessor and we have to learn to code in assembly language using atmel studio 7
01:56 AM rue_: I have 32 and 64
01:56 AM Emil: top kek
01:57 AM Emil: rue_: why do you insist on being wrong?
01:57 AM z999: emil, the class purpose is to learn asm
01:57 AM Emil: z999: ah
01:57 AM Emil: z999: wellthen check out polprogs and rue's asm tutorials
01:57 AM rue_: Emil, if you give me taht check page again, I'll show ya the lsit
01:57 AM z999: thanks emil
01:57 AM rue_: z999, http://ruemohr.org/~ircjunk/datasheets/atmelinstructions.pdf
01:57 AM nuxil: z999, also this is also something you want http://polprog.net/papiery/avr/avr-asm-instruction-set-manual.pdf
01:57 AM nuxil: arg. you beat me
01:57 AM rue_: that is an important doc thats hard to find
01:58 AM z999: yeah i know assebly language is no longer used in the field but this class requires it
01:59 AM nuxil: asm is used all over the place
01:59 AM nuxil: its not dead
01:59 AM Emil: The percentage of use is preeeeetty small, though
01:59 AM z999: i heard it is not used
02:00 AM Emil: it is used
02:00 AM nuxil: Emil, indeed.
02:00 AM Emil: If you want high performance you sometimes need it
02:00 AM Emil: when the compiler is being stupid
02:00 AM nuxil: and time critical stuff
02:00 AM Haohmaru: maybe inline asm
02:00 AM Haohmaru: cpp ftw
02:00 AM nuxil: meh
02:01 AM Haohmaru: * language fight *
02:01 AM * Haohmaru hides
02:01 AM Emil: Hmm
02:01 AM nuxil: C is to bloated for mcu's :p
02:01 AM Emil: I need a low power display
02:01 AM nuxil: C++
02:01 AM nuxil: :p
02:01 AM Haohmaru: Emil put a series resistor on it
02:02 AM Emil: lol
02:02 AM nuxil: epaper ?
02:02 AM z999: https://pastebin.com/VcuYq2BZ
02:03 AM z999: i pasted the assignment and the code below
02:03 AM Emil: nuxil: too expensive and I don't need it to last without power
02:03 AM Emil: z999: and what's the issue
02:03 AM nuxil: static lcd ?
02:03 AM Emil: you have a simulator
02:03 AM Emil: nuxil: dunno what that specifically means
02:03 AM z999: yes it is in stimulator mode
02:03 AM z999: emil, when i build i have 0 errors
02:03 AM Emil: z999: so what's the issue then
02:04 AM z999: i am not sure about the flags
02:04 AM Emil: check the simulator
02:04 AM z999: if the flags in red is something wrong with the code?
02:04 AM nuxil: Emil, static lcd ? really . its thouse low power lcd you find in calulators, multimeters etc .
02:04 AM z999: emil, is the code ok to you for the purpose of the assignment?
02:05 AM Haohmaru: i doubt an ASM program will tell you about anything being "wrong"
02:05 AM Haohmaru: unless you mistyped some constant ;P~
02:05 AM Haohmaru: or syntax error
02:05 AM z999: Haohmaru i am very new to this. i thought that if the flags are in red that something is wrong with the code
02:05 AM Emil: z999: bro
02:06 AM Emil: z999: we don't have your simulator
02:06 AM z999: emil: call me sista
02:06 AM Emil: no
02:06 AM z999: emil: yeah that is the problem. if you do not have atmel it is harder for you to help me.
02:07 AM Emil: also
02:07 AM z999: emil: trying to say i am a girl. please don't call me bro.
02:07 AM Emil: you don't need the dollar sign
02:07 AM z999: 0x92
02:07 AM Emil: dunno what the prupose of it is
02:07 AM z999: is the same as $92 right?
02:07 AM Emil: or if it means decimal then dunno
02:08 AM z999: $92 is hex i think
02:08 AM Haohmaru: it means dollars
02:08 AM Haohmaru: it must be hex.. cuz $F5
02:08 AM z999: it is hex
02:09 AM Haohmaru: could it be that certain things are red because they "changed" their state since last clock cycle or something?
02:09 AM Emil: z999: ah true
02:09 AM Haohmaru: is this in the simulator or in the IDE?
02:09 AM Emil: Haohmaru: *
02:09 AM Haohmaru: que?
02:09 AM Emil: Haohmaru: regarding it being hex
02:09 AM Emil: just use the 0x prefix
02:09 AM Emil: imho much more readable
02:09 AM z999: Haohmaru it could be. again, i am new and do not know how to interpret the flags
02:10 AM Haohmaru: i do
02:10 AM nuxil: z999, you dont need a sim to "inspect" the flags. do it manually. go though your code stp by stp
02:10 AM Haohmaru: Emil i don't write asm (nor understand it)
02:10 AM nuxil: z999, example the C flag is set 0 if a zero result in an arithmetic or logic operation.
02:10 AM z999: nuxil, part of the assignment is to report the flags. only reason i am asking
02:11 AM Emil: z999: then read the flags and write them down
02:11 AM nuxil: read up on SREG for your chip.
02:11 AM z999: on the link you gave me?
02:11 AM nuxil: in the datasheet for your current chip.
02:11 AM Haohmaru: more like in the datasheet
02:12 AM Haohmaru: if you're lucky, the datasheet may contain small example codes in ASM
02:12 AM Haohmaru: for doing this and that
02:12 AM nuxil: isnt sim's unreliable anyway ?i think i heard it is. idk tho
02:13 AM Haohmaru: nuxil you ARE simulated ;P~
02:13 AM nuxil: :D
02:13 AM Haohmaru: there is no spoon
02:13 AM z999: thank you guys
02:14 AM z999: i will try to do a little more coding
02:14 AM z999: and read more of the god awful textbook/manual
02:14 AM z999: i think instructor posted the datasheet in moodle
02:15 AM Haohmaru: the datasheet can be downloaded from the manufacturer's website
02:15 AM Haohmaru: but that may not be too easy now, thanks to microsh<backspace,backspace>chip
02:15 AM rue_: http://ruemohr.org/~ircjunk/datasheets/atmelinstructions.pdf
02:15 AM rue_: ^^^^ that
02:15 AM rue_: is a hard one to find its NOT in the datasheet
02:16 AM rue_: they do have a summary in the datasheet
02:16 AM nuxil: yea. that pdf will explain how the instructuons work.
02:17 AM nuxil: download and save it
02:17 AM Haohmaru: isn't starting up with ASM harder than starting up with C?
02:17 AM nuxil: yea
02:17 AM rue_: z999, is there a particular programming thing your trying to do now?
02:17 AM rue_: it depends on the goal
02:17 AM rue_: if your goal is understanding how a cpu works, asm is good
02:17 AM Haohmaru: aren't you a bit tied with the processor with asm?
02:17 AM Haohmaru: sure
02:18 AM rue_: it your goal is complex trig math, I dont even know if C can help you
02:18 AM Haohmaru: but most people want a LED to light up
02:18 AM nuxil: hehe
02:18 AM nuxil: good old blinky
02:21 AM z999: rue_ i am trying to do coding for act 2
02:21 AM z999: one moment and i will share with you the instructions
02:22 AM z999: https://pastebin.com/urM2iJ8A
02:23 AM polprog: nuxil: <3
02:23 AM z999: i am doing this LDI r20, $99 then MOV r20, r0
02:23 AM z999: i am suppose to do an ldi for r0 too?
02:23 AM rue_: do you know what ldi and mov do?
02:24 AM rue_: http://ruemohr.org/~ircjunk/datasheets/atmelinstructions.pdf
02:24 AM rue_: ^^^ look them up
02:24 AM z999: ldi is to load the value to r20
02:24 AM rue_: see what they do to the flags
02:24 AM z999: i thought that mov was to move it to r0
02:24 AM z999: ok rue
02:26 AM z999: i get an error when i build
02:26 AM z999: the way i did it is wrong
02:26 AM z999: so i must do something to R0 so it recognizes it
02:29 AM polprog: what kinda error do you get?
02:29 AM z999: syntax error
02:29 AM polprog: whats the line and what assembler do you use?
02:30 AM z999: oh my bad
02:30 AM z999: i forgot a comma
02:30 AM polprog: hehe
02:33 AM z999: ok this is what i did. i build it and no errors. I haven't checked the flags yet
02:33 AM z999: does this look right?
02:33 AM z999: https://pastebin.com/uhUt3t1f
02:34 AM polprog: yes, make sure that the operand order is correct
02:34 AM polprog: that depends on the assmebler i think
02:34 AM z999: ok i will check the textbook again
02:34 AM z999: brb
02:35 AM polprog: not the textbook i think
02:35 AM polprog: unless you use the same assembler that the text book uses
02:35 AM z999: polprog the class textbook has the instruction of operand order
02:36 AM z999: that is why i went to get it to refer to it
02:36 AM z999: polprog yes the textbook is simply for coding asm in arduino/atmel studio 7
02:36 AM polprog: okay,
02:37 AM polprog: sounds right
02:37 AM polprog: just remember that if you happen to use another toolkit (or syntax) the order of operands may be different
02:37 AM z999: anyone interested in the textbook? there is pdf online
02:37 AM polprog: sure
02:37 AM polprog: ;)
02:40 AM polprog: its worth to collect things like that
02:41 AM nuxil: where
02:42 AM Haohmaru: if it was paper, i could use it to light up the fire
02:42 AM z999: i can't find the 2nd edition
02:42 AM z999: online
02:42 AM z999: my friend found it and i can't find that link now
02:42 AM z999: i googled and i see the 1st edition which is not the edition i am using
02:43 AM z999: maybe one of you are more resourceful than me
02:44 AM z999: i will post the amazon link and maybe one of you can find the 2nd edition
02:45 AM z999: this is the book https://www.amazon.com/Microcontroller-Embedded-Systems-Using-Assembly/dp/0997925965/ref=sr_1_1?s=books&ie=UTF8&qid=1517474631&sr=1-1&keywords=ali+mazidi
02:45 AM z999: if you find the online pdf please let me know!
02:47 AM nuxil: it was most likely some pirated.
02:47 AM nuxil: all the books i see costs.
02:47 AM polprog: thats why i read HOWTOS
02:47 AM nuxil: found this tho :p http://web.csulb.edu/~hill/ee346/Lectures/01%20Intro%20Assembly.pdf
02:48 AM polprog: also, oracle made a pretty good x86 assembly reference. and they even let you dl it as pdf
03:21 AM dgriffi: has anyone tried to use an AVR to homebrew a general purpose computer on par with something like a commodore 64?
03:22 AM dgriffi: or some CP/M machine?
03:37 AM nuxil: so far this day is good, i just got this in my mail :) https://gyazo.com/da83729cf27e12f5963884a9de82128d
03:42 AM polprog: dgriffi: i think theres a BASIC computer that has composite output based on an avr
03:43 AM polprog: nuxil: cool !
03:46 AM nuxil: the only thing i didnt like about it tho. is that the min temp on the soldering iron is 200 deg.
03:46 AM nuxil: but that no big deal.
03:49 AM polyfuse: [09:22] <z999> i thought that mov was to move it to r0 -hey girl ;) yes well mov in asm means copy the value
03:49 AM dgriffi: I seem to recall someone coming up with a homebrew console called "x-box" sometime before Microsoft came out with their console.
03:52 AM polyfuse: z999: you should not do asm in arduweenie script, it is mixing cool stuff (asm) with scripts (arduweenie), there is ASM, and C if you want to make things simpler, and as mentioned, C++ is too bloat() for mcu
03:52 AM polprog: nuxil: too low?
03:53 AM polyfuse: i started with asm too, and i think it is nice to know what the cpu is actually doing
03:57 AM nuxil: polprog, to high imo as a minmum setting. my other solering iron goes from 120 dec to 400. this one is 200-400
03:58 AM nuxil: but as said no biggy. you cant solder at that low temp anyway.
03:59 AM polprog: i solder at 250 and some say thats too low ;)
03:59 AM Emil: polprog: wtf
03:59 AM Emil: niga
03:59 AM Emil: why
03:59 AM nuxil: it is
03:59 AM Emil: 350 or go home
03:59 AM polprog: why is it too low exactly?
04:00 AM Emil: polprog: you'll find that soldering becomes an enjoyable experience
04:00 AM nuxil: 250 is not enuf heat.
04:00 AM polprog: i can do it fast and good at 250.
04:00 AM Emil: just
04:00 AM Emil: why
04:00 AM Emil: at least go to 300
04:00 AM polyfuse: polprog: i choose 315°C for SnPbAg
04:01 AM polprog: flux evaporates too fast at 300. its a rosin core solder
04:02 AM polyfuse: polprog: we are talking about soldering iron ?
04:02 AM polprog: yeah
04:03 AM polyfuse: polprog: ofc, i use paste, that is a different thing, the flux needs to be activated at 150°C
04:04 AM polyfuse: polprog: in a reflow oven you don't go above 270°C, and most likely above 240°C, and first preheat to 150°C
04:04 AM polprog: i also do hot air with a buthane iron, but thats only for when i need a tqfp soldered/desoldered
04:05 AM polyfuse: polprog: i don't know what temps i heat up stuff with my iron, but i know when it flows right then time to take it away.
04:06 AM polyfuse: polprog: one can use any temp betwen 300°C and 400°C with practice
04:06 AM polyfuse: even 450°C, and semotimes it is needed if the thing needs a lot of heat
04:07 AM Haohmaru: i'll invent a "smart" iron
04:07 AM dgriffi: do any of you use a through-hole desoldering rig?
04:07 AM polprog: i can see my iron tip dying at 400 c
04:07 AM polyfuse: happens often
04:08 AM Haohmaru: put it in a small coffin
04:08 AM polyfuse: Haohmaru: good ones have temperature regulation
04:08 AM polprog: i may try 300 next time, maybe even today
04:09 AM polyfuse: Haohmaru: you can get decent irons for 100-200 eur
04:09 AM nuxil: you do not want to use wet sponge at 400+ deg. to much termal stress on the tip. it will wear out in no time.
04:09 AM Haohmaru: polyfuse i use a 5euro iron
04:09 AM polyfuse: Haohmaru: i have a 10 year old worn down german iron that i bought for 10 eur and still works
04:09 AM polprog: i use a wire rag
04:10 AM Haohmaru: i soldered a whole drum machine (all tht stuff) and the tip is still sharp as f***
04:11 AM polyfuse: this? https://www.aliexpress.com/item/Soldering-Iron-Tip-Cleaner-with-Wire-Sponge-Detin-Tools-Clean-Copper-wire-more-quickly-and/32800052987.html
04:12 AM nuxil: thouse are best for high temp if you want to make your tip last longer. a wet sponge makes the tip a bit cleaner but wears it out faster.
04:13 AM nuxil: Haohmaru, did you take out the tip and see how much termal compound left on it ?
04:13 AM Haohmaru: i use a similar thing (actually it's kitchen scrubbing metal mesh thing) plus i pour water in the little spunge thing and wipe the tip often
04:13 AM Haohmaru: wiping the tip into the wet spunge also reduces the temperature shortly
04:14 AM Haohmaru: nuxil wut?!
04:14 AM Haohmaru: i don't even get the question
04:14 AM nuxil: Haohmaru, yea. good tips has some termal stuff on them
04:15 AM Haohmaru: *shrug*
04:15 AM Haohmaru: this is a 5euro iron with a cheap tip
04:16 AM Haohmaru: that is held inside with a small screw
04:17 AM Haohmaru: this is my iron: http://elimex.bg/userfiles/productlargeimages/product_74354.jpg
04:18 AM polyfuse: haha check this out, google's car went in a hospital https://www.google.de/maps/@25.851764,-80.281926,3a,66.8y,108.62h,65.2t/data=!3m4!1e1!3m2!1sCAoSLEFGMVFpcFAxZzdaTDJQTjhWbEJpZUd4b0NjY3ZtTkY0MmxBbE54UjRVWlo3!2e0
04:19 AM nuxil: Haohmaru, o.O
04:20 AM polyfuse: Haohmaru: i made tip from copper rod and i clean it with wire cutter or sandpaper
04:20 AM nuxil: get a real soldering iron. you have no control with the heat on that.
04:21 AM nuxil: Haohmaru, you can find real cheap soldering station for $25 on ebay.
04:21 AM polyfuse: Haohmaru: it is badly worn, but stil could wedge the tip in the heating element with a needle
04:43 AM dgriffi: polyfuse: Google employs backpacks with camera stuff like those found on a Google Car.
04:44 AM dgriffi: polyfuse: that's how they get images for trails
05:12 AM mindw0rk_ is now known as mindw0rk
06:52 AM nohit: nuxil how much you paid for that handskit 909d+
08:55 AM polprog: http://paste.debian.net/1008347/
08:56 AM polprog: i wrote that makefile myself but i must be missing some options for the linker
08:56 AM polprog: any tips how to fix that?
08:57 AM cehteh: are you sure the symbols missing are defined in the library you link?
08:58 AM polprog: im not
08:58 AM polprog: brb
08:58 AM cehteh: also iirc sometimes the order matters, try object first, then library
08:59 AM polprog: wow that was it
09:00 AM polprog: thanks very much cehteh, id never think about that
09:00 AM cehteh: btw can the arm toolchain do lto?
09:10 AM polprog: i dont know. (lto = link time optimization?)
09:17 AM rue_: polprog, why did you write a makefile I have one that works
09:19 AM rue_: http://ruemohr.org/~ircjunk/avr/mega32/makefile
09:21 AM Emil: libs are to be linked last
09:21 AM Emil: if we are talking c compilation
09:21 AM rue_: modify it all ya want
09:21 AM Emil: specified
09:21 AM rue_: its my current mega32 version
09:22 AM rue_: I keep specific versions for the avrs I use
09:22 AM rue_: m32, m328 t26, t13, m8, m88, t85
09:23 AM rue_: the general rule of their operation is that there is a .h file for every .c file, even if empty, and it compiles all the .c files into one project
09:24 AM rue_: so, what I do, is to have a dir called, say atmega32 with the makefile in it, and under that I have a project dir, with all the files for that project in it, and a link back to the makefile
09:25 AM rue_: `-- tiny85
09:25 AM rue_: |-- 74LS166
09:25 AM rue_: | |-- main.c
09:25 AM rue_: | |-- main.h
09:25 AM rue_: | `-- makefile
09:25 AM rue_: go in and use /make clean/make/make usbinstall
09:26 AM rue_: for the m328 I have a make arduinoinstall
09:26 AM rue_: leverage the arduino bootloader on baords that came with it
09:27 AM polprog: rue_: i did not understand all the dependencies. i wanna learn them and thats why i wrote mine
09:27 AM rue_: k, its evil
09:27 AM polprog: i took hints from the one thats in the root dir of stm32.tgz from your site
09:28 AM polprog: as for linker options
09:28 AM rue_: for an avr?
09:29 AM rue_: stm32 is still new, something will come out that will solidify everything
09:30 AM rue_: a proper package for creating a build environment will be one of them
09:31 AM rue_: I had to do a fair bit of adjustment to get the stm32 stuff togethor
09:31 AM polprog: for stm, see paste link there
09:31 AM polprog: any tips welcome
09:31 AM rue_: but I had some experience from the old avr days
09:31 AM polprog: ill now add a make flash command and make radare that runs radare for code examination
09:31 AM rue_: I suggest setting up your environment so my makefile works for ya ;)
09:32 AM polprog: i think that id just need to change the lib path (mine is in a local dir cloned from github)
09:32 AM rue_: you will save days of trouble just using my makefile install code
09:33 AM polprog: youare right
09:33 AM rue_: yea, you DO NOT WANT the main library in your project dir, you want it to be shared
09:33 AM polprog: ill just go ahead and try yours, and when i get it working ill add the radare opt as well
09:33 AM rue_: thats one of the immediate gripes I had with what I saw
09:33 AM rue_: the project dir should only need to have your projects source files in it
09:34 AM rue_: like that tiny85 tree
09:34 AM rue_: the project it called 74LS166, the source files are main.c and main.h, the makefile is just a link
09:34 AM rue_: make; make install
09:34 AM rue_: done.
09:35 AM rue_: so
09:36 AM polprog: i have a programming/stm32 dir and in it theres library directory and project dirs. LIBPATH is defined as ../libopencm3
09:36 AM polprog: because they advised against global install of the library
09:36 AM rue_: an aliexpress seller didn't reply 3 times when I asked them to extend purchase protection because time was running out, so it did, and I had to open a dispute, which is over (refund) and now they are asking me for positive feedback....
09:37 AM rue_: polprog, do you have the avr libraries installed?
09:37 AM rue_: maybe under /usr/lib/avr ?
09:37 AM polprog: i have avr libs installed from repo
09:37 AM polprog: why are we talking about avr
09:37 AM rue_: where tho
09:37 AM polprog: i dont know myself where :P
09:37 AM rue_: because I mimmiced the method for stm32
09:38 AM rue_: look up the location of avr/io.h
09:38 AM rue_: put the libraries under an stm32 version
09:39 AM polprog: its in /usr/lib/avr
09:39 AM rue_: so, maybe /usr/lib/arm
09:39 AM polprog: maybe
09:39 AM rue_: it makes sense
09:40 AM rue_: usr/lib/arm/include/libopencm3/stm32/usart.h
09:43 AM polprog: would that allow me to drop -I and -L arguments?
09:43 AM polprog: where arm-none-eabi-gcc would look for libs
09:44 AM polprog: cos if i would have to write -I /usr/lib/arm/libopencm3/includes then its in practice the same as keeping the lib where i have it now
09:45 AM polprog: wait im blind
09:45 AM rue_: thats the dir I used.
09:45 AM polprog: there is /usr/lib/arm-none-eabi
09:45 AM polprog: duh... ill put that there
09:45 AM rue_: so if you put the libopencm3 stuff there, then my makefile should work
09:46 AM rue_: k, so in my makefile, change 'arm' to 'arm-none-eabi'
09:46 AM polprog: i dont wanna have "loose" files in there. i will change the variables in your makefile for my setup
09:47 AM rue_: ok
09:49 AM McDonaldsWiFi: rue_: I ordered some tri-state buffers!
09:49 AM McDonaldsWiFi: so we'll see how this goes in a few days ^^
09:49 AM polprog: rue_: whats the licence on that makefile :P ?
09:49 AM rue_: McDonaldsWiFi, did you see my last note?
09:49 AM rue_: polprog, public domain
09:49 AM rue_: could you add that?
09:49 AM rue_: and cc me?
09:49 AM rue_: wait, is there a carbon tax on cc ing things?
09:49 AM McDonaldsWiFi: rue_: nope, lemme scroll up! was it last night?
09:49 AM polprog: add a note that its PD and you are the author?
09:49 AM polprog: sure
09:50 AM McDonaldsWiFi: rue_: aww...
09:50 AM McDonaldsWiFi: rue_: I made my order without seeing the final answer :O lemme look at my parts list now lol
09:50 AM rue_: McDonaldsWiFi, with a 74ls138, 74ls365 and 74ls174 you can get 6 inputs and 6 outputs
09:51 AM rue_: but I dont know if your making it as a card that needs to do thte rest of the address decoding
09:51 AM rue_: oops, my credit card changed and ruemohr.org almost expired on me!
09:51 AM McDonaldsWiFi: I thought about buying a z9- SIO for decoding
09:51 AM rue_: :-S
09:52 AM McDonaldsWiFi: but I'm not sure yet. Once i move this to a PCB ill prolly add hardware for decoding
09:52 AM McDonaldsWiFi: z80 sio*
09:52 AM rue_: McDonaldsWiFi, I used two 741ls138, one for 8 memory CS and one for 8 io CS
09:54 AM McDonaldsWiFi: I bought.. 4 attiny's because why not.. 4x 74HCT245s, 4x SN74LS373N's, 4x SN74HC595N, and 4x 74HCT166
09:54 AM McDonaldsWiFi: soo.. nothing on your list
09:54 AM McDonaldsWiFi: LOL
09:54 AM McDonaldsWiFi: fml
09:55 AM McDonaldsWiFi: https://trmm.net/AVR_RFID
09:55 AM McDonaldsWiFi: you guys seen that, super interesting attiny abuse
09:55 AM McDonaldsWiFi: ?
09:56 AM McDonaldsWiFi: powered by leakage current and uses the internal protection diode to rectify the ac
09:59 AM Haohmaru: so ghetto
10:00 AM rue_: push it to the max! :)
10:00 AM polprog: rue_: i have a question on variables in your makefile. Theres a DEVICE and LDSCRIPT one. they seem to have the same value. But LDSCRIPT is not defined anywhere
10:01 AM rue_: polprog, it might have been something I missed when I was composing it from things
10:01 AM rue_: I took a lot f things and made a lot of changes
10:03 AM rue_: oooh wait, I think
10:03 AM polprog: i have a file called bluepill.ld which is the script i pulled from some repo and it seems that your makefile is looking for $(DEVICE).ld
10:03 AM rue_: yea
10:03 AM rue_: thats to do with that funny libopencm thing
10:03 AM polprog: but thats odd as i dont see where LDSCRIPT is defined
10:04 AM rue_: the one that results in stm32f103c8t6.ld
10:07 AM rue_: I wasn't thrilled about that, but it wouldn't clean out
10:07 AM _ami_: polprog: u could use https://github.com/amitesh-singh/libopencm3-proj-template
10:07 AM _ami_: its based on meson/ninja
10:07 AM polprog: hmm. i tried recompiling with your makefile. gcc has the same -I param but fails to compile
10:08 AM rue_: libopenCM3Path =/usr/lib/arm
10:08 AM rue_: did you fix that
10:08 AM polprog: yeah i did
10:08 AM * _ami_ hates makefiles eew!
10:09 AM rue_: polprog, dump me what it gives you
10:09 AM polprog: my bad was VIM undid my change and $DEVICE was empty. which caused the gcc invocation to contain -T -I ...
10:09 AM rue_: ah
10:09 AM polprog: :P
10:09 AM rue_: _ami_, are you using something built into an editor?
10:09 AM _ami_: no
10:09 AM _ami_: its comamnd line
10:09 AM _ami_: just clone
10:10 AM _ami_: modify libocm3 path and add ur cpp files
10:10 AM _ami_: thats it.
10:10 AM _ami_: and build.
10:10 AM rue_: ... your solution to avoid make is bash?
10:10 AM _ami_: ?
10:11 AM _ami_: what?
10:11 AM rue_: I'm reading, but almost out of time, need to go to work
10:11 AM polprog: oh jesus. i have 100% cpu usage when i scroll the file in vim haha
10:11 AM _ami_: i hate modifying ugly tab shit makefiles
10:12 AM rue_: wait, _ami_ how do you set the gcc optimization level or the includes? like -lm/
10:12 AM _ami_: -Os is there
10:13 AM _ami_: check meson.build
10:13 AM polprog: also why some target defs have semicolons after colons, like "telnet:;"
10:13 AM rue_: in the end, it looks just as evil as a makefile
10:14 AM rue_: I didn't writ the telnet line
10:14 AM _ami_: no, makefile is shit!
10:14 AM _ami_: u r wasting ur time if you are modifying plain makefiles
10:14 AM polprog: _ami_: ./make.sh ?
10:14 AM rue_: the other thing is that the makefile is just one file
10:15 AM rue_: you need build.sh, cross-file.txt and meson.build
10:15 AM rue_: to replace a makefile
10:15 AM rue_: and really, meson.build looks JUST AS UGLY as a makefile
10:16 AM _ami_: lol
10:16 AM polprog: i started to like makefiles after messing with TensorFlow needed Bazel installed. that install takes 1GB, which is 10% of the / partition on the virtual machine
10:16 AM _ami_: have fun with makefiles then! :)
10:16 AM rue_: already did, it works
10:16 AM polprog: and it takes 30 seconds to process the command line args before it even starts invoking gcc
10:17 AM polprog: enterprise build system my ass
10:17 AM * rue_ snickers
10:17 AM rue_: well its got to execute 1G of code!
10:18 AM _ami_: those who worked on a project which has millions line of code knows what a relief meson/ninja brings to their project.
10:19 AM rue_: hah
10:20 AM rue_: building bloatware? heh anyhow, I wont say that makefiiles are perfect, sometimes they just help you recompile less files
10:20 AM rue_: personally, I HATE implied stuff, and thats most of what make is
10:21 AM polprog: rue_: do you want the makefile?
10:21 AM rue_: later today
10:22 AM polprog: ok
10:22 AM rue_: trying to leave for work
10:22 AM polprog: have a nice day!
10:22 AM Haohmaru: turn the oven off!
10:23 AM rue_: I wonder, if you have a hello world.c and a blank makefile, if it'll compile it
10:23 AM Haohmaru: blank?
10:23 AM Haohmaru: just use an IDE with a build system
10:23 AM rue_: yea, betweent eh defaults and the implied stuff
10:23 AM * Haohmaru hides
10:24 AM rue_: I'v never found a list of the implied and defaults of make
10:24 AM rue_: pretty sure cc=gcc
10:24 AM Haohmaru: if it compiles something, then will you even know what you got?
10:24 AM Haohmaru: ;P~
10:24 AM * rue_ hops around on one foot trying to find his other shoe
10:25 AM polprog: gcc *.c
10:25 AM rue_: and elf
10:25 AM polprog: :P
10:25 AM rue_: I think thats how elvs are made
10:27 AM _ami_: wow, avr-binutils & arm-binutils upgrade this time. https://www.enlightenment.org/ss/e-5a733fa66e91e5.48345856.png
10:29 AM Emil: _ami_: you might want to look at https://developer.arm.com/open-source/gnu-toolchain/gnu-rm/downloads
10:30 AM polprog: oh. i will have to pacman -Syu my laptop as well then
10:31 AM _ami_: Emil: i am on arch. always updated :)
10:32 AM _ami_: polprog: do it! :)
10:32 AM _ami_: hopefully it does not break our projects. :P
10:33 AM Emil: _ami_: nice
10:33 AM Emil: Debian has rather old
10:34 AM polprog: i dont worry about that.. i have win avr installed on windows machine, so its a backup gcc that is several minor versions old lol
10:34 AM Emil: polprog: well
10:34 AM _ami_: win-avr is so ancient :P
10:34 AM Emil: you basically don't want to use GCC>=5
10:34 AM Emil: Because of regression
10:36 AM polprog: i have avr-gcc 5.4.0 on this debian (unstable) and 7.2.0 on arch laptop
10:36 AM polprog: i wonder what winavr has
10:36 AM polprog: whoops
10:37 AM polprog: i wonder if there is any avr-gcc in nyetbsd pkgsrc
10:38 AM _ami_: win-avr development has been stopped long time ago.
10:38 AM _ami_: AFAIK
10:39 AM polprog: i better upload that makefile on my mirror cos when he's back from work ill be sleeping on the other side of this countru
10:40 AM polprog: s/u/y
10:41 AM Emil: polprog: 4.7-.9 is like best perf
10:42 AM polprog: shame sdcc doesnt target avr
10:42 AM polprog: is there any other compiler for avr?
10:42 AM polprog: except for avrstudio
10:43 AM jragon: I thought avrstudio was just an idea and still used the normal avr tool chain with avr-gcc
10:43 AM jragon: idea*
10:43 AM jragon: ide*
10:43 AM polprog: i think they do.
10:43 AM jragon: neat, I didn't realise
10:44 AM polprog: since atmels docs on avr-libc were word for word like the savannah site
10:44 AM jragon: http://ww1.microchip.com/downloads/en/DeviceDoc/50002712A.pdf
10:45 AM jragon: Page four says it requires the avr-gcc toolchain
10:45 AM jragon: Annoyingly it doesn't have great support for actually programming chips. If you want to use usbasp you have to set up a task to do it
11:05 AM polprog: flash write_image erase program.elf
11:05 AM polprog: "no flash bank found for address 0"
11:05 AM polprog: hmm?
11:15 AM polprog: oh wait i was flashing program.bin
11:15 AM polprog: dug
11:15 AM polprog: duh*
11:34 AM polprog: finally
11:35 AM polprog: its blinking
11:35 AM Jartza: who is?
11:35 AM polprog: the led
11:35 AM Jartza: it's always good to have a led or few blinking :)
11:35 AM polprog: nah, finally wrote a program for stm32
11:35 AM polprog: :D
11:37 AM Jartza: cool
11:38 AM Jartza: I always have something flashing on my breadboard stack
11:39 AM Jartza: https://youtu.be/U0cFXo0K96g
11:52 AM Emil: polprog: avrstudio is gcc
11:52 AM Emil: avr-libc is an open source project from atmel
11:55 AM polprog: oh. nice!
11:59 AM Jartza: although they use their own modded gnu toolchain
12:49 PM nohit: does 1 seat mean 1 computer ?
12:49 PM nohit: or 1 user
12:59 PM nuxil: 1 seat is a single user iirc.
01:00 PM nuxil: but i find this word confusing and dont like it.
01:02 PM nohit: nuxil where did you get that d909+ and how much did it cost ?
01:02 PM nohit: 909d+

01:03 PM nuxil: there are cheaper varians that is just 2in1.
01:03 PM nohit: no i want that 4in1
01:04 PM nohit: 110e shipped
01:04 PM nuxil: all that stuff on the pic is included.
01:05 PM nuxil: are you gonna get one ?
01:06 PM nohit: yes
01:06 PM nohit: is that yellow terminal fixed +30 V ?
01:07 PM nohit: and red adjustable ?
01:07 PM nuxil: i havent played with the psu on it yet. i jus turned it on and off and ye the red is adjusteble.
01:07 PM nuxil: been testing the heatgun ;)
01:08 PM nuxil: i can go check.
01:08 PM nuxil: brb
01:19 PM nuxil: so the yellow one. is for testing voltages upto 30V
01:19 PM nuxil: its input
01:20 PM nuxil: output is 0-15V
01:21 PM nuxil: so its kind of like a crude voltmeter
01:23 PM nohit: ok
01:23 PM nohit: thanks
01:24 PM nuxil: np
01:34 PM nuxil: nohit, are you living in usa or eu ?
01:35 PM nohit: finland
01:35 PM nuxil: if you order one. make sure you get ther correct one. there are 110V and 220V variants.
01:35 PM nohit: yes i noticed
01:53 PM nuxil: nohit, so are you gonna buy a (seat) single user license for some designer tool ?
01:55 PM nuxil: just be a pirate :p altium and the rest of the pcd designer tools are way overcharged for personal usage. no wounder there are cracked for most of these apps.
01:57 PM nohit: i was just wondering what "1 seat" means in my eagle student license. apparently it is 1 user with 2 installs.
01:58 PM nohit: and i dont pirate
01:59 PM nuxil: a seat should not be resticted to a computer. let say you have a 2 seat license. that means that 2 users can use the software at same time while if a 3rd one tries. he wil be blocked and needs to wait until a user logs off
01:59 PM nuxil: https://en.wikipedia.org/wiki/Per-seat_license
01:59 PM nuxil: not sure if thats the way eagle does it.
02:00 PM nuxil: nohit, i dont pirate either. but at times i feel tempted to be one :p
02:01 PM Emil: nohit: time to migrate to KiCAD
02:01 PM nuxil: jup
02:02 PM nuxil: kicad is become de facto standard for hobbyists.
02:59 PM nuxil: does anyone know of or have a list with pictures of all packages types for resitors, caps, transitors, chips etc.
03:08 PM nuxil: polprog, your the kind of guy that goes around collect alot of stuff from the inet. do you have anything like this ? ;)

03:28 PM Thrashbarg: http://blog.mbedded.ninja/pcb-design/component-packages <-- not an image but it's pretty extensive
03:40 PM nuxil: oh nice
03:40 PM * nuxil download that page
03:42 PM APic: yay
05:18 PM nuxil: so i was going though my email and sort out packages that has arrived from ebay. does anyone have experiance with Ebay and claim a refund ? i bought a cheap usb microscope the 25/12/2017. and the est delivery was suppose to be 26 jan this year.
05:18 PM nuxil: https://www.ebay.com/itm/USB-Microscope-Endoscope-1000X-2MP-8LED-Digital-Magnifier-Camera-Black-Exquisite/192398303485?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2057872.m2749.l2649
05:19 PM nuxil: that one. but on the shipping time it says it can take up to 39 days.
05:19 PM nuxil: do i wait ?
05:20 PM nuxil: but heres another scetchy thing. the seller i bough it off was named. es-easybuy . and now he is called il1t6l1o02 with no item in the store.
05:20 PM LeoNerd: I did one eBay refund lately which involved a dispute about what the seller had sent
05:20 PM LeoNerd: For things that simply go missing, could be postal service anywhere inbetween. That's a trickier one
05:21 PM nuxil: yea
05:21 PM nuxil: but i got the feeling this guy is a scammer.
05:21 PM nuxil: maybe i should wait the 39 days.
05:26 PM nuxil: oh wait. its 39 days today
05:42 PM Casper: they will say to wait a week
05:42 PM Casper: so do it now
05:42 PM Casper: after the week it will really start
05:44 PM nuxil: oki. meesage to the seller sent.
05:55 PM nuxil: 1st bad experiance on ebay. guess it was inevitable.
05:55 PM nuxil: *it is
05:56 PM nuxil: Casper, you been trough it before ?
05:57 PM Casper: yes, seller never responded
05:58 PM Casper: no answer from seller = automatic win
05:58 PM nuxil: ok
05:59 PM Casper: funny thing is... aliexpress, some sdr dongle... seller never replied... ebay, sdr dongle, seller never replied... amazon, sdr dongle, seller mever replied :D
06:01 PM polprog: whats a good , robust and universal bench meter? doesnt have to be brand new. would be nice to have a computer interface though
06:02 PM nuxil: some fluke
06:02 PM polprog: i thought they did only habdheld devices
06:02 PM polprog: handheld*
06:03 PM nuxil: no.
06:04 PM nuxil: https://www.ebay.co.uk/itm/Fluke-8000A-Portable-Bench-Digital-Multimeter-USED/172326988610?hash=item281f7d2b42:g:qWYAAOSwMgdXyJwY
06:04 PM nuxil: used old one
06:05 PM nuxil: if you want brand new. expect to pay up around $800++
06:07 PM polprog: hmm. looks good
06:07 PM nuxil: lol.. ebay sucks. i set item location to EU and it lists items for usa & cannada :p
06:07 PM polprog: but a bit too old
06:08 PM polprog: and that too. customs is just a lot of walking in here :P
06:08 PM nuxil: what's your budget?
06:11 PM polprog: yeah baby! flukr 8000A for a similar price but local from poland
06:11 PM nuxil: im still looking for a DMM myself. i got 300bucks saved up a new DDM. im aslo starting to save up for a new scope aswell. still missing a few hunderds bucks for that :p
06:12 PM polprog: i got a brymen, the one with 50000 counts. it was about 250 quid
06:12 PM nuxil: which one ? 869s ?=
06:13 PM polprog: i think ues
06:13 PM polprog: yes*
06:13 PM nuxil: yea i want that one.
06:13 PM polprog: damn that fluke has only 3 digits. any dmm nowadays has 4
06:13 PM nuxil: tried to find a seller on ebay. found one in italy but he wanted 50€ for shipping.
06:14 PM nuxil: i was like. wtf dude. thats like 1/4 of what its worth
06:14 PM polprog: i guess i will have to go look in local shops. damn it will cost more
06:14 PM nuxil: yea alot more :)
06:14 PM polprog: :/
06:15 PM polprog: i was thinking, maybe a used agilent. or HP
06:16 PM nuxil: hey.. maybe i can send you money and you go buy me a 869S and ship it too me :p and ofc give you extra for work and shipping. aslong as its under 300 buck :p
06:17 PM polprog: haha
06:17 PM nuxil: :D
06:17 PM nuxil: isnt agilent keysight now ?
06:20 PM polprog: holy crap. some chink bench meter is like £800. i guess i will just put my brymen on its stand.
06:23 PM nuxil: yea i would too :p
06:28 PM nuxil: polprog, look up Uni-T bench multimeter
06:28 PM nuxil: they seemsto be cheap
06:29 PM LeoNerd: I've seen the Uni-T bench meter. Honestly it isn't much more than one of their handhelds, in a bench case
06:30 PM LeoNerd: It doesn't have the sort of specs you'd expect of an /actual/ bench meter
06:30 PM nuxil: i just heard crap about uni-t
06:31 PM nuxil: but idk. i havent seen one myself
06:31 PM LeoNerd: Some of their stuff is decent enough. I have the UT61E handheld meter.. it's nice
06:31 PM LeoNerd: 60k count
06:31 PM LeoNerd: ER.. no, 35k. Not 60
06:31 PM nuxil: thats still good
06:34 PM polprog: the only real advantage that bench meter would have to have, is nore accuracy/resolution than this brymen handheld i have. if somebody want to sell me one that can display max 4 digits at once, well, i guess bot
06:34 PM polprog: not*
06:34 PM polprog: i will just get a new one when i save enough
06:35 PM nuxil: polprog, https://www.ebay.co.uk/itm/VICI-Digital-Multimeter-VC8145-Bench-Top-Voltmeter-PC-DMM-80K-Digit-AC-DC-Tester/112626421530?epid=2240755641&hash=item1a390ecf1a:g:fWsAAOSwBRFaPH3u
06:35 PM LeoNerd: Yeah; my UT61E has 5 digits on it anyway
06:35 PM polprog: saw that one
06:35 PM LeoNerd: You can get 5-digit handhelds
06:35 PM polprog: too expensive for now and its from china so customs
06:36 PM polprog: i think that brymen has a 6 digit mode on VDC
06:37 PM polprog: maybe i could just get a serial cable for it for the price and make it datalogging
06:37 PM LeoNerd: The UT does serial too
06:38 PM polprog: ill have to think about it
06:38 PM polprog: night
06:38 PM nuxil: gn
06:39 PM polprog: this vici china one look moderately good
06:40 PM nuxil: it looks ok.
06:40 PM nuxil: LeoNerd, whats the difference between your 61E and 61D ?
06:40 PM LeoNerd: Loooooads
06:41 PM nuxil: k
06:41 PM LeoNerd: They're massively different. The E is the only one with the full count. They're entirely different meters
06:41 PM LeoNerd: Uni-T have a slightly odd style of version numbers. That trailing letter is a lot more meaningful than you might expect
06:45 PM nuxil: hmm. that 61e dosent look bad ar all
