12:17 AM polprog: morning
12:35 AM day__ is now known as day
01:21 AM Jartza: morning
01:35 AM rue_ is now known as rue_mohr
01:41 AM Haohmaru: (rue_mohr + rue_less) = rue_avg
01:51 AM rue_shop4: :/
01:51 AM rue_shop4: damn, I ordered a roll of 0.5mm solder when what I wanted was 0.8
01:51 AM rue_shop4: there goes $20
01:52 AM rue_shop4: good thing I didn't order the expensive one
01:59 AM polprog: maybe it expanded due to temperature in your shop
01:59 AM polprog: or your calipers shrunk :^)
02:03 AM rue_shop4: no, I just checked and I ordered the wrong thing
02:03 AM polprog: i just got a pair of digital calipers
02:03 AM polprog: i wonder how they work, as i dont see any gray code or any other encoder strip
02:04 AM polprog: and they seem to be reasonably accurate, as i slid them quickly halfway open and then slammed them back to zero, and they read only -0.01 mm
03:19 AM rue_shop4: capacitive vernier encoder
03:19 AM rue_shop4: its got like 8 channels
03:33 AM Haohmaru: rue_shop4 throw that 0.5mm solder into a mix of water and baking soda.. let it soak for 1.6 hours
03:57 AM nuxil: polprog, get a vernier caliper, much better :p
03:57 AM nuxil: i had a couple of digitals ones in the past. must say i prefere the manual ones better.
03:57 AM polprog: nuxil: do you think i dont have a vernier caliper?
03:57 AM polprog: :P
03:58 AM polprog: ive got 3 in the house at least, best one, stainless steel, in workshop
03:58 AM nuxil: good for you.. -+0.1 is bad for a digital :p my current vernier does 0.05 :p twise as good
03:58 AM nuxil: as your digital
03:58 AM polprog: thats +-0.01 mm for the whole 15 or so cm it does
03:59 AM polprog: my vernier one is similar "resolution"
03:59 AM nuxil: oh i misread.
03:59 AM nuxil: i saw 0.1
03:59 AM nuxil: :p
03:59 AM polprog: heh
03:59 AM nuxil: yea 0.01 is ok tho..
04:02 AM polprog: rue_shop4: nice, thats an interesting encoder, thanks :p
04:42 AM nuxil: rue_shop4, why u no like 0.5mm .. 0.5mm is good :)
04:45 AM nuxil: i once asked my friend if he could pick up some 1mm or less solder for me when he was in the neighbor town.
04:45 AM nuxil: i should have specified that.., if you dont find 1mm or less dont buy. cos when he came back he gave me a big roll if 2mm solder.
04:46 AM nuxil: with no flux
04:46 AM nuxil: and it costed almost 400kr :p
04:46 AM nuxil: i just told him i'll never ask a favor of this kind again :p
04:52 AM nuxil: hmm
04:52 AM nuxil: anyone seen this. https://blog.arduino.cc/2018/05/17/say-hello-to-the-next-generation-of-arduino-boards/
04:52 AM nuxil: FPGA
04:53 AM eimiar: i've read that in my mind with al pacino's voice
04:53 AM nuxil: a video from hackaday https://www.youtube.com/watch?time_continue=103&v=v9lIn2mYdlo
04:54 AM nuxil: a bit expensive. $60
04:55 AM nuxil: eimiar,
04:55 AM nuxil: is your PI working fine now as a programmer ?
04:56 AM eimiar: i didn't try yet to program my avr, but i soon will
04:56 AM eimiar: for now i only tested reading the avr flash contentes
04:56 AM eimiar: *contents
04:56 AM nuxil: ok
04:58 AM eimiar: actually in my next steps i wanna try and see if i can use my tumpa-lite as a programmer
04:59 AM eimiar: i might have to patch avrdude to use libmpsse for that
05:00 AM Emil: >wot
05:03 AM nuxil: i think this new arduino "vidor" will be a failure. dont think it will sell many.
05:07 AM Haohmaru: what kind of a dumb name is that
05:08 AM nuxil: its expensive. it got no pins on the header.( you need to solder it yourself.). coding for fpga afik is not like coding in C/C++
05:09 AM nuxil: and it got a camera on the pcb for what purpose ? learn video encoding/decoding ?
05:09 AM Haohmaru: nah, so that teh NSA can see what ur doin
05:10 AM Haohmaru: it probably also has a microphone
05:11 AM Haohmaru: and of course, connectivity to teh internetz
05:14 AM polprog: magnificient device
05:15 AM * polprog uplaods a crypto miner for fpgas into teh bootloade
05:15 AM polprog: r
05:15 AM Haohmaru: le manifiq(ue)
05:15 AM polprog: fucking keyboard
05:15 AM polprog: cest un dispositif manique
05:15 AM polprog: manifique*
05:15 AM Haohmaru: le wat
05:16 AM polprog: damn
05:16 AM Haohmaru: pls no french
05:16 AM polprog: porquoi :(
05:16 AM polprog: mange mon baguette
05:16 AM Haohmaru: moi no schprechen zi french
05:17 AM Haohmaru: did google translate crash on that? >:)
05:20 AM polprog: gonna try and install some Tcl lib i need to run insight
05:20 AM polprog: it compiled but doesnt start, shows a dialog saying it cant find some library...
05:21 AM polprog: it was in aur, but i was messing with the scope at the same time so i didnt notice why it didnt install
05:22 AM Haohmaru: aur.. was that an archlinux thing?
05:56 AM nuxil: i though real men use gentoo :p
06:39 AM LeoNerd: Well, colour me surprised. All three nFETs I've just put on this board seem to be static-damaged
06:39 AM LeoNerd: Two showing open short, one that my Peak declares "depletion-mode FET" despite that it should be a normal enhancement n
06:40 AM LeoNerd: I've always known in theory that FETs are quite static-sensitive, but so far I've never actually popped one. Certainly not all three on the same board at the same time
06:44 AM nuxil: 1st time for everything :)
06:50 AM nuxil: aslo.
06:50 AM * nuxil slaps LeoNerd with a antistatic mat and a wristband.
06:52 AM LeoNerd: I have a mat
06:52 AM LeoNerd: I have an entire ESD floor in my workshop
06:52 AM nuxil: oh.
06:52 AM nuxil: well shit happens
06:53 AM LeoNerd: And a grounded iron
06:53 AM LeoNerd: I suspect these were dead before I even got them out of the bag
06:53 AM nuxil: what kind os fet's where they? hope it was small signal fets and not expensive big power fet's :p
06:53 AM LeoNerd: They came shipped loose in a polythene baggie
06:53 AM LeoNerd: 2N7000
06:53 AM LeoNerd: Oh, cheap as chips.. I have hundreds=
06:53 AM LeoNerd: It's just a pain to have to swap them out of the board
06:54 AM nuxil: indeed.
06:54 AM nuxil: what are you makeing btw ?
06:55 AM nuxil: these 2n7000 seems like some alright small signal fet's. i should order some :)
06:57 AM nuxil: rdsOn a bit high tho.
07:00 AM LeoNerd: ATtiny13, 3 nFETs for LEDs, ISP connector, LiFePO4 battery. It just displays blinky light patterns
07:03 AM rue_bed: none of the 2n7000 I'v got from china in non-antistatic bags were a problem
07:03 AM rue_bed: and I dont use any esd
07:03 AM rue_bed: LeoNerd, can you show the circuit your using them in?
07:04 AM LeoNerd: It's hardly fancy
07:05 AM LeoNerd: ATtiny13, with 2N7000 gate on each of PB0-2, grounded sources. drains + a VCC out to LEDs
07:20 AM rue_bed: k
07:58 AM polprog: hehe. is that some theater thing? blinky? or a joke project?
08:00 AM LeoNerd: Theatre prop, yah
08:00 AM LeoNerd: A lot of my makings are :)
08:16 AM nuxil: Do you got a act named: To blink or not to blink. Using your props :p?
08:44 AM polprog: here is a nice pic for you
08:44 AM polprog: https://puu.sh/AqdIF/b506c0f4aa.jpg
08:44 AM polprog: im walkng round the city because i finished school earlier and im meeting my cousin
08:49 AM polprog: its the center of warsaw, right noe
08:49 AM polprog: now*
09:29 AM enh: beautiful city
09:34 AM polprog: finally going home
09:34 AM polprog: i just need to buy graph paper
09:34 AM polprog: maybe ill try to fix the scanner later or do some video montage
09:43 AM Haohmaru: video montage of faked UFO sighting
09:43 AM Haohmaru: with chupa-cabra in the bushes
09:45 AM polprog: close
10:18 AM polprog: you know what would be nice
10:19 AM polprog: a super bright white led, the size of a maglite mini lightbulb
10:19 AM polprog: im afraid mine will burn out some day
10:19 AM polprog: and its not that bright anyway
12:29 PM Ameisen: Hmm
12:30 PM Thrashbarg: hmm
12:30 PM Ameisen: didn't know that GCC already had support for so much of C++2a draft
12:30 PM Ameisen: default member initializers for bitfields
12:30 PM Ameisen: neat
12:30 PM Ameisen: and designated initializers
12:30 PM Ameisen: double neat
12:30 PM Ameisen: lots of poeple want those, but they're still not as powerful as people want
12:34 PM APic: ☺
01:34 PM Tom_itx is now known as Tom_L
01:48 PM polprog: https://twitter.com/polprogpl/status/998620492776034304?s=19
02:09 PM nuxil: polprog, noise from psu your listening to ? what frequency is tha 16hz, 166hz ?
02:10 PM nuxil: or 16k .. swtiching noise
02:25 PM polprog: it was from the lightbulb
02:26 PM polprog: fluorescent "energy saving"
02:27 PM rue_shop4: yes, all you have to do is cantaminate your area with mercury!
02:28 PM rue_shop4: * cant type over breakfast bowl with skillz
02:29 PM polprog: bon apetit
02:29 PM polprog: i should get some supper
02:31 PM nuxil: hey youre not fooling me.. you made a antenna with Lambda ~ 6cm. 1/2 wavelengt of 2.5Ghz wifi :p
02:44 PM nuxil: In VS is there a "Block Comment" function for selected text like there is in notepad++ ?
04:05 PM Emil: Gah I fucking hate the fucking javascript apis that browsers offer
04:05 PM Emil: why can't you just give me a fucking blocking api
04:05 PM Emil: and let me thread it for fucks sake
05:01 PM polprog: nuxil: timebase is visible on that pic, do your maths :D
05:01 PM polprog: im rendering a vid
05:20 PM polprog: hehehehehe
05:20 PM polprog: AAC is giving up on Oscillofun's sharp edges, compression introduces a bit of noise
05:20 PM polprog: even at max quality
05:29 PM polprog: enjoy
05:29 PM polprog: https://www.youtube.com/watch?v=wS8SfjMQ2Qc
05:53 PM Emil: ohboi
05:53 PM Emil: it werks
05:54 PM Emil: fuck yeah
06:04 PM polprog: i just notices that 1 vpp signal thats meant to be 1khz... is not exactly 1khz on screen
06:04 PM polprog: so i guess ill have to open it, RTFM and correct the timebase gen
06:05 PM polprog: i think calibration is described in there
