12:31 AM nuxil: Jartza, i could not resist, i orderted a tevo tarantula :D
12:37 AM Jartza: nuxil: cool :)
12:37 AM Jartza: although now is CNY, so it might take a while for it to ship
12:37 AM nuxil: yea.
12:55 AM Jartza: nuxil: Tevo ships with DHL or UPS, so it won't pass customs
12:55 AM Jartza: the logistics company will handle customs anyway and bill you :P
12:59 AM nuxil: what you mean? dlh post ship custom bills ?
01:01 AM nuxil: i got the soldering station delivered by dhl. no bill attached. but the multimeter i ordered i needed to pay 400kr in custom befoer getting it delivered. it was not by dhl. but by my national mail serive. they took over the deliver after it arrived my contry.
01:04 AM nuxil: so idk. maybe i was just 1time lucky :p
01:06 AM nuxil: anyway. i dont order stuff i cant afford. i must alway put on 20% extra on price from forren contry when i look at stuff above 350kr. so if it passes the custom undeteced i just see it as a 20% sale :p
01:31 AM Casper: The custom can be prepaid or post paid
01:31 AM Casper: more and more sellers actually do it prepaid, because it reduce the complains and also make it often faster to ship
01:32 AM Jartza: nuxil: at least in finland, DHL asks for invoice and then sends bill for customs & taxes
01:33 AM Jartza: in finland, the VAT is 24% :(
01:39 AM Casper: here in quebec, 14.975%
02:55 AM polprog: morning
04:55 AM Emil: good day :D
07:26 AM day__ is now known as day
09:54 AM mudkip908_ is now known as mudkip908
10:41 AM Jartza: well. firmware size now: 510 bytes :D
10:41 AM Jartza: there's 512 bytes of flash in the chip
10:41 AM Jartza: maybe I just add one asm("nop") for fun, to fill it up
10:41 AM polprog: put your initials in ASCII in those two bytes!
10:42 AM Jartza: :)
10:42 AM Jartza: I could do that too!
10:42 AM Emil: Jartza: what firmware?
10:42 AM Jartza: but probably I'll optimize it a bit lower
10:42 AM Jartza: Emil: e-cigarette :P
10:42 AM Emil: lolwat :D
10:42 AM Jartza: or what they are called nowadays, vape thingamabobs
10:43 AM polprog: is that work or for yourself/friend
10:43 AM Jartza: helping friend's business
10:43 AM _ami_: has anybody used https://sigrok.org/wiki/PulseView ? is there any guide on making it work with other custom usb hardware?
10:44 AM polprog: _ami_: i did , what hardware
10:44 AM polprog: ?
10:45 AM _ami_: polprog: i have a stm32f103 which spits out analog value at bulk endpoint. i wonder if i could resuse pulseview
10:46 AM Emil: isn't pulseview like digital data
10:46 AM _ami_: Emil: it supports analog too.
10:46 AM Emil: oh cool
10:46 AM _ami_: https://www.enlightenment.org/ss/display.php?image=e-5a85b55fa2e4c5.07897081.jpg
10:47 AM Emil: nice
10:47 AM polprog: _ami_: pulse view for analog is not very useful
10:48 AM _ami_: polprog: oh
10:48 AM _ami_: its slow?
10:48 AM polprog: you could try making a tool program that dumps the values into a file and open it in pulse view
10:48 AM _ami_: oh, its offline analyzer?
10:49 AM polprog: it supports "live" display of data
10:49 AM polprog: its that the most useful decoders if not all work on digital traces
10:50 AM polprog: (but if you set low sample rate and zoom out, you can see the signals in real time)
10:50 AM polprog: but the "online" part works only if pulseview would directly communicate with the device
10:50 AM _ami_: polprog: yeah, i am interested in that.
10:51 AM _ami_: how to add support for a device.
10:51 AM polprog: i havent ever needed to do it, id take a look at the source code and ask in their devel mailing list
10:52 AM polprog: i think ive seen some tiny pieces of information on the sigrok wiki
10:52 AM polprog: because pulseview is just the GUI, i think that would be devel list or wiki for libsigrok
10:59 AM _ami_: polprog: thanks.
10:59 AM _ami_: i asked them on twitter. https://twitter.com/sigrokproject
10:59 AM _ami_: lets see
11:00 AM _ami_: i don't think adding a device support should be hard. its just data.
11:00 AM _ami_: this will save my effort. i don't want to write an application like pulseview
11:00 AM polprog: yeah, they have pretty good support for many things, so it might be a case of adding another module
11:03 AM _ami_: https://sigrok.org/wiki/Protocol_decoder_API/Queries
11:09 AM Jartza: my 3D printed 18650 battery holders seem to work pretty well
11:09 AM polprog: http://assets.amuniversal.com/96cfe460e74a013512ef005056a9545d

11:11 AM polprog: that spring is pretty cool!
11:13 AM Jartza: https://i.imgur.com/yhDWQfn.jpg
11:14 AM Jartza: it also works nicely
11:15 AM _ami_: Jartza: looks nice as well.
11:17 AM Jartza: yeah
11:21 AM polprog: "Danger: Do not use outside" :P
11:26 AM _ami_: polprog: https://sigrok.org/wiki/Hardware_driver_API
11:26 AM _ami_: this is what i need.
11:26 AM Jartza: well, I'm gonna cover those screws with heat shrink when cable is connected
11:26 AM _ami_: its in C
11:26 AM _ami_: so easier for me. :)
11:27 AM polprog: good
11:27 AM polprog: i would never think its that easy
11:46 AM polprog: huh
11:46 AM polprog: i go by there every day and havent noticed that its a hyperbolic paraboloid
11:46 AM polprog: https://en.wikipedia.org/wiki/Warszawa_Ochota_train_station
12:18 PM unregisterednick: who needs breadboard? :) https://www.youtube.com/watch?v=3rZcX6kO3Tg
12:20 PM nuxil: o.O ffs . please donate 1 breadboard to that guy :p
12:22 PM nuxil: do some wrong calc or just put in the wrong resistor size and you be burning down your house :p
12:22 PM learath: nuxil: feature not bug? :P
12:22 PM nuxil: hehe
12:23 PM antto: what is that thing he solders with o_O
12:30 PM polprog: im pretty surprised
12:30 PM polprog: he doesnt even have a DMM
12:37 PM unregisterednick: polprog: here is how they make your himidifier in china :) https://www.youtube.com/watch?v=Fhkg6cmWKO4
12:38 PM unregisterednick: humidifier
12:38 PM unregisterednick: antto: it is a stepdown transformer heating a pierce of copper wire...
12:42 PM unregisterednick: antto: here is the high tech version diyed https://www.youtube.com/watch?v=gHWia5K7Hso
12:42 PM nuxil: stop watching crap like that :p
12:45 PM nuxil: unregisterednick, go watch Eevblog, Franlab, Mr calson's lab, Great Scott and channels like that :p
12:46 PM unregisterednick: nuxil: he did this and does not even have a cross screwdriver lel
12:46 PM unregisterednick: nuxil: i dont but these were interesting
12:53 PM _ami_: GreatScott is GreatCrap. :P
12:55 PM nuxil: _ami_, way better than the stuff unregisterednick posted :p
12:56 PM _ami_: :)
12:57 PM unregisterednick: hay _ami_
12:57 PM unregisterednick: _ami_: did you see my vampire and poker multimeter attachments? ;>
01:02 PM unregisterednick: i dont know about you but i have not seen anything like this quality for sale at affordable price around here yet https://www.youtube.com/watch?v=bfku1lMPP1k lithium battery operated soldering iron, and they can even diy this in india...
01:07 PM nuxil: just no. no no no.
01:08 PM nuxil: if you want to do electronics. get a proper iron with tmp control.. or atleast one of thouse cheap weller ones.
01:09 PM _ami_: unregisterednick: just buy a good soldering iron.
01:10 PM _ami_: those are very cheap in india. ~ 400/- INR
01:10 PM unregisterednick: _ami_: i have soldering irons, and even heat guns, and i can pulse tig weld 1mm things, but i want a better small battery operated smd hacking soldering iron
01:11 PM unregisterednick: _ami_: im in central europe btw
01:11 PM _ami_: oh ok
01:12 PM _ami_: what do you mean they can even diy this in india?
01:12 PM _ami_: its about talent not resources
01:14 PM nuxil: doing soldering with usb 5v gonna be 1 amp is gonna make crappy solders. thats 5w. and n% of that goes into loss. you need a iron of 40W++ to get good termal transfere.
01:14 PM nuxil: so that makes you 5v usb port draw min 8 amps.
01:14 PM nuxil: :E
01:14 PM _ami_: usb won't get 1A
01:14 PM _ami_: at max 0.5A
01:15 PM _ami_: give*
01:15 PM nuxil: so even worse :p
01:18 PM _ami_: polprog: downloaed libsigrok & pulsview repos. looked at Saelogic-pro hardware implementation into libsigrok lib. https://sigrok.org/wiki/Saleae_Logic_Pro_16
01:18 PM _ami_: i can implement the support for my hardware. its a week project for me. :)
01:21 PM _ami_: time to sleep.
02:35 PM unregisterednick: you don't have an IR desoldering station yet? https://www.youtube.com/watch?v=1Mq_5BWGnxU
02:35 PM unregisterednick: [20:09] <_ami_> what do you mean they can even diy this in india? [20:09] <_ami_> its about talent not resources - that, and resources
02:36 PM unregisterednick: [20:12] <nuxil> doing soldering with usb 5v gonna be 1 amp is gonna make crappy solders. thats 5w. and n% of that goes into loss. you need a iron of 40W++ to get good termal transfere. - i know what i need to solder a 0402 resistor ar capacitor...
02:37 PM unregisterednick: definituly not 35W
02:37 PM unregisterednick: definitely not 35W
02:37 PM unregisterednick: soldering iron
02:42 PM nuxil: unregisterednick, tell that to every professional soldering station manufacturur out there :p
02:43 PM unregisterednick: nuxil: i dont have to
02:44 PM unregisterednick: actually they can make and sell whatever they can and want to
02:49 PM nuxil: i must ask how much sodering have you done? because you seems to miss the grasp of termal transfere. if you put a 5v usb thingy "2.5w" iron tip on a pad. all the heat is getting eaten up by the pad. dosent matter if its 200deg. you cant keep pump enough engergy in there to keep it hot enuf to get a proper solder joint.. you need a bigger iron, there is loss termal everywhere.
02:50 PM unregisterednick: nuxil: well i did some since 2000
02:50 PM unregisterednick: nuxil: not counting
02:57 PM nuxil: unregisterednick, if you want a poteble sodering iron. perhaps gas driven one is what you want. someting like. http://www.pro-iroda.com/pro70.htm
03:04 PM unregisterednick: nuxil: definitely na
03:05 PM unregisterednick: nuxil: lithium batteries can be charged thousands of times
03:05 PM unregisterednick: anywhere
03:08 PM nuxil: why no laser soldering iron made yet? :p
03:09 PM nuxil: oh there is
03:10 PM unregisterednick: https://www.youtube.com/watch?v=K6zBpl_NKIw good, he forgot the heatsink for the 110W led though ;)
03:11 PM nuxil: i got one of thouse.. its a awefull pize of crap :p
03:12 PM nuxil: heatsinks are over rated :p
03:15 PM unregisterednick: haha crap?
03:15 PM unregisterednick: it doesn't heat up?
03:18 PM learath: unregisterednick: you mean "the weird soldering iron"?
03:18 PM nuxil: totaly useless for the stuff i do. :p i rarly solder wires size bigger than 3-4mm.
03:20 PM unregisterednick: learath: i have no clue you are talking about now
03:21 PM unregisterednick: but i did bring up a broad range of soldering methods
03:22 PM polprog: oh those pistol type irons
03:22 PM polprog: ideal for quick smd rework :^)
03:22 PM polprog: i have one of those
03:24 PM unregisterednick: smd? lel
03:25 PM unregisterednick: i was rather thinking wire soldering
03:25 PM polprog: s/wire/pipe/g
03:25 PM polprog: and if you can solder copper pipes, the microwave RF world is all yours
03:25 PM polprog: :P
03:26 PM unregisterednick: or all the water you want transported by copper pipes, some even distill booze with them
03:26 PM polprog: if you have a good worskhop, why limit yourself to electronics
03:46 PM polprog: especially if you have a hand to chemistry :^)
04:59 PM unregisterednick: russian hackers bonding fpc to lcd screen https://www.youtube.com/watch?v=QtY1QH120-I
05:56 PM Jartza: gcc is drunk
05:56 PM Jartza: 128: 00 c0 rjmp .+0 ; 0x12a <__DATA_REGION_LENGTH__+0x2a>
05:56 PM Jartza: 12a: 00 00 nop
05:57 PM Jartza: it makes that kind of stuff in my code
06:03 PM Jartza: maybe asm ftw
06:14 PM cehteh: padding? space for debugger breakpoints (which would be odd on AVR, but gcc does that)
11:15 PM day__ is now known as day
