12:00 AM NoHitWonder^: i would rather download the files
12:05 AM NoHitWonder^: you have to name all the files when you rip
12:05 AM NoHitWonder^: and if you buy LP's you cant really rip
12:05 AM NoHitWonder^: since the record companies already have the files ready, its unnecessary work for the customer
12:09 AM NoHitWonder^: iirc some (small record?)comapny in finland provided cd + mp3's with the same price
12:21 AM dgriffi2: ripping and tagging cds is effortless
12:28 AM NoHitWonder^: it might be effortless, but it takes time and time is money
01:01 AM polprog: iirc my ripper would name and tag by itself
01:02 AM polprog: i just had to put tye cd and start it
01:07 AM ohsix: https://abcde.einval.com/wiki/ didn't even know it existed :p last time i did it i used eac/lame
01:10 AM dgriffi2: I use abcde on Linux
01:10 AM dgriffi2: rips, compresses, and tags
01:12 AM ohsix: gotta try and find a cd to try it on :p
01:14 AM ohsix: there was a lot of voodoo with mmc drive support and audio streaming and other junk only EAC was purportedly able to deal with, dang it's been a long time
01:19 AM polprog: i think sound juicer was the one i used
01:20 AM ohsix: sweet. the only cd i have to hand is tool - ænima
01:21 AM ohsix: the reason why æ ended up in so many of my passwords
01:56 AM Emil: NoHitWonder^: no, but our library might have it
01:56 AM Emil: or if they dont
01:56 AM Emil: I can have it ordered for the library :D
01:57 AM Emil: why so?
01:58 AM grog_c is now known as Grogdor
02:01 AM NoHitWonder^: just curious. its a great book
02:05 AM ohsix: by far the reading of the cd is the slowest part, even encoding to several formats is much faster than realtime
02:18 AM Emil: Hmm
02:18 AM Emil: I wonder if I should buy any programming books
03:14 AM NoHitWonder^: hello enhering
03:53 AM skz81: <Emil> I wonder if I should buy any programming books >> On some topic in particular ? Or generally speaking ? by the way, I recommand "the Pragmatic Programmer"
04:09 AM Emil: skz81: just based on NoHitWonder^'s recommendatiob
04:09 AM Emil: Since
04:10 AM Emil: I don't really know what I could gain from them
04:10 AM Emil: that is not available on the internet already
04:11 AM NoHitWonder^: well its a good book but its mainly for beginners, so there's nothing new to you really
04:11 AM NoHitWonder^: but its good book to have
04:27 AM skz81: Emil, ok. The one I quote, despite more aimed to *software* engineers (i guess), i far beyond pure technical considerations. It's from 1999 and I didn't even notice it was that old while reading it !
04:27 AM skz81: is* far
04:29 AM skz81: Another entry but some will shout at me : "Real Time C++" by Christopher Kormanyos.
04:30 AM skz81: (C++11 ; AVR 8 comptatible ^^ )
05:05 AM BongoShaftsbury: anybody know what protocol car keys use for their remotes
05:06 AM Emil: BongoShaftsbury: many different kinds
05:06 AM Emil: most modern ones use quite many tricks
05:06 AM BongoShaftsbury: for my class project i wanted to write one that listens for signals and then emulates them
05:07 AM daey: its not a static signal
05:08 AM daey: you can easily see the signal with a SDR Receiver. its in the 433Mhz band iirc
05:09 AM daey: or at least roughly in that spectrum
05:09 AM Emil: most are yeah
05:10 AM BongoShaftsbury: okay but what do you mean by non static signal
05:10 AM daey: you cant just record and replay it
05:10 AM Emil: BongoShaftsbury: then just get a rtlsdr and some chip that does multiple modulations in 433MHz
05:10 AM daey: it will be different every time
05:10 AM Emil: daey: sure you can, if the type is old
05:10 AM Emil: but modern ones yeah
05:10 AM Emil: you cannot do replay attacks
05:10 AM daey: "modern"
05:11 AM daey: i doubt it would work on any half decent car made in the 21th century
05:12 AM BongoShaftsbury: so some keys are trancievers
05:12 AM BongoShaftsbury: not just transmitters
05:13 AM Emil: No they are quite often only transmitters
05:13 AM daey: not sure about that
05:13 AM daey: but they are paired so they have common knowledge that you do not have which they can use
05:15 AM BongoShaftsbury: i think it is pretty cool but may be difficult to do in 2 weeks
05:15 AM Emil: Depends
05:16 AM Emil: if you are not half bad you can do it
05:16 AM Emil: if you can dedicate the whole two weeks
05:16 AM BongoShaftsbury: well my team of 5 only has two competent people and the other guy got hit by a car
05:16 AM Emil: You need to acquire, filter, analyse and extract
05:16 AM Emil: and then you can just send
05:17 AM Emil: Have you done any research into it?
05:17 AM Emil: Loads of articles detail what you ask
05:17 AM BongoShaftsbury: just filtering through ideas atm
05:17 AM BongoShaftsbury: not set on one particular one just thought that one was cool
05:18 AM daey: i would probably implement it on a raspberry first
05:18 AM Emil: It is cool
05:18 AM BongoShaftsbury: has to be an atxmega a3bu
05:18 AM Emil: you could use some TI CC series
05:18 AM Emil: or
05:18 AM daey: gl then. the decoding alone will be a challenge
05:18 AM Emil: si 44 series
05:18 AM BongoShaftsbury: i could hook it up to a pi
05:18 AM Emil: totally fine
05:19 AM Emil: matey
05:19 AM Emil: you are not analysing the signals on an avr ;)
05:20 AM daey: what is the reason for using that specific µC?
05:21 AM daey: seems like an odd choice for a class project to me
05:21 AM BongoShaftsbury: uc?
05:21 AM Emil: micro
05:21 AM Emil: controller
05:21 AM BongoShaftsbury: oh i see
05:21 AM BongoShaftsbury: it is the one provided to me
05:21 AM Tom_itx: no �C
05:22 AM Emil: ?
05:22 AM Emil: BongoShaftsbury: what level course is this?
05:22 AM BongoShaftsbury: junior
05:22 AM Emil: Uni first year?
05:22 AM BongoShaftsbury: 3rd
05:22 AM Emil: EE?
05:22 AM Emil: ECE?
05:22 AM BongoShaftsbury: cecs
05:23 AM BongoShaftsbury: the course is for EE ECE and CECS
05:23 AM daey: yeah i figured it would be provided. i just found it strange that they would choose an atxmega and not the of the mill mega88 or mega324
05:23 AM Emil: daey: I bet they taught about DMA and shit on that course
05:23 AM Emil: needs an xmega for that
05:23 AM BongoShaftsbury: DMA?
05:24 AM daey: ah didnt know they have that
05:24 AM Emil: Well
05:24 AM Emil: apparently not :D
05:24 AM daey: :D
05:24 AM Emil: daey: perhaps their school just had a representative visit and upsold them
05:24 AM BongoShaftsbury: from what i understand it's what the school got for free
05:25 AM daey: you are probably right. one unit to satisfy all needs
05:25 AM Tom_itx: figures
05:25 AM Emil: BongoShaftsbury: what has been done before?
05:25 AM Emil: on that course
05:25 AM BongoShaftsbury: saw some laser tag, a super extensive graphics library for the LCD
05:25 AM BongoShaftsbury: some music / light combination
05:25 AM Emil: Do you have a budget?
05:25 AM BongoShaftsbury: infinity dollars
05:25 AM Emil: Do you only have 2 weeks for it or is this just because of slacking off?
05:26 AM Emil: Well
05:26 AM Emil: that's nota bad budget
05:26 AM daey: i would personally go for something non wireless :P
05:26 AM BongoShaftsbury: it's due in early july
05:26 AM Emil: so two weeks
05:26 AM daey: when did it start? :D
05:26 AM Emil: And you have slacked off
05:26 AM Emil: it's fine
05:26 AM Emil: Every student does it
05:26 AM Emil: It's always just amusing seeing it happen :D
05:26 AM daey: yeah lol
05:26 AM BongoShaftsbury: well the proposal and part list is due july 1st
05:27 AM Emil: Ah so the project plan is due july 1st?
05:27 AM BongoShaftsbury: yes
05:27 AM Emil: And then you order and do it?
05:27 AM Emil: And you have until when to finish it?
05:28 AM BongoShaftsbury: july 6th is what i am seeing
05:28 AM Emil: wtf
05:28 AM daey: rofl
05:28 AM BongoShaftsbury: but i think that will be pushed back
05:28 AM Emil: how can you only have a single week to program and develop
05:28 AM BongoShaftsbury: i think that's a miscommunication between the prof and the TA
05:28 AM Emil: or you have not been awake enough? ;)
05:28 AM Emil: Anycase
05:29 AM Emil: Yeah like daey said, wireless is a pita
05:29 AM Emil: but if you can pull it off it's nice
05:29 AM Emil: since you are cecs you could write a simple os for it
05:29 AM Emil: have a scheduler, shell and shit
05:29 AM daey: anyhow my standing is it's better to do something easy good than to do something difficult bad
05:29 AM Emil: yuå
05:29 AM Emil: yup
05:29 AM Emil: Agreed
05:30 AM daey: i would check the datasheet of the atx and see what nice features it has.
05:30 AM daey: nes rom dumping might be one project if you insist on "hacking"
05:30 AM Emil: BongoShaftsbury: what's the target of the course/project
05:31 AM Emil: daey: too easy imho
05:31 AM daey: yeah but so are lcd libaries
05:31 AM Emil: quite
05:31 AM daey: i dont know their level
05:31 AM Emil: probably not too high
05:31 AM Emil: I've come to not expect much from students :D
05:31 AM BongoShaftsbury: :D
05:32 AM daey: lowest common denominator problem :(
05:32 AM Emil: yup
05:32 AM Emil: but it's also that very few analyse different solutions and ideas
05:32 AM Emil: like
05:32 AM Emil: they see a solution and just go for it
05:32 AM BongoShaftsbury: well my team mates include 2 senior EE students who needed me to explain the oscilloscope to them
05:32 AM Emil: without spending much time thinking about alternatives and so on
05:32 AM daey: BongoShaftsbury: did you have signal analysis filters etc?
05:32 AM Emil: BongoShaftsbury: :DD
05:33 AM BongoShaftsbury: never done any signal analysis
05:33 AM Emil: BongoShaftsbury: "senior"
05:33 AM daey: Emil: as in 'they are older' :p
05:33 AM Emil: BongoShaftsbury: pardon my apparent racism but were they not natives?
05:33 AM BongoShaftsbury: as in they are year 4
05:33 AM daey: nice
05:33 AM BongoShaftsbury: 90+ hours and yes
05:34 AM Emil: It's a strange observation I've had
05:34 AM Emil: Though I bet there's some bias
05:35 AM Emil: Exchange students seem to lack basic skills a lot of time
05:35 AM Emil: but eh
05:35 AM BongoShaftsbury: not much i can do about it i can't teach them fast enough to be up to speed w/ what's going on
05:35 AM BongoShaftsbury: so i will have to do it myself
05:35 AM Emil: Have you tried giving them a chance?
05:35 AM daey: you failed the first and most important part
05:36 AM Emil: I mean, it might backfire
05:36 AM daey: picking the right group
05:36 AM daey: :D
05:36 AM Emil: But it's still the right thing to do ;D
05:36 AM Emil: BongoShaftsbury: so what's on your list now?
05:37 AM BongoShaftsbury: i tried to let them wire a circuit was a usb 9pin serial -> 232cpe chip -> j1 header of the board and they jacked it up
05:37 AM Emil: lol
05:37 AM BongoShaftsbury: and then asked them to code a part of an earlier project and nothing got done
05:37 AM Emil: hehe
05:37 AM Emil: Yeah
05:37 AM Emil: you might be alone on this one :D
05:37 AM BongoShaftsbury: they just spent 45 minute asking me questions
05:37 AM BongoShaftsbury: slowing me down on my part
05:37 AM Emil: Have you tried talking to your prof/teacher?
05:37 AM BongoShaftsbury: i'm not worried about my team mates
05:38 AM BongoShaftsbury: i've accepted i'll have to do it
05:38 AM Emil: If you make your case clearly you might not have to carry them
05:38 AM BongoShaftsbury: i still have to do the project if they are on my team or not
05:38 AM Emil: sure
05:38 AM Emil: but if you really think you can do it better alone and that they would only drag you down
05:38 AM Emil: you can ask about it from your prof
05:38 AM Emil: but if you do
05:38 AM Emil: make the case clearly
05:39 AM Emil: And without emotion
05:39 AM Emil: And also do list what's on your list as interesting projects
05:39 AM BongoShaftsbury: that's what i'm looking into, things that i think are interesting
05:39 AM BongoShaftsbury: that way i can work on and learn about things i find appealing
05:40 AM daey: btw. what about pcb manufacturing time?
05:40 AM daey: or is it a free wiring project?
05:40 AM BongoShaftsbury: free wiring
05:40 AM Emil: daey: if they have unlimited budget
05:40 AM Emil: lololol
05:41 AM daey: Emil: yeah but 1week :P
05:41 AM BongoShaftsbury: think PCB is out of the scope
05:41 AM Emil: how is this a 3rd year project
05:41 AM daey: well granted that fits lol
05:41 AM Emil: how the fuck can a 3rd year project be like the ones we do here first year :D
05:41 AM Emil: well
05:41 AM Emil: it's a rhetorical question
05:41 AM Emil: Anycase
05:42 AM Emil: if you do have a bit more time
05:42 AM Emil: What country are you in?
05:42 AM Emil: If the states
05:42 AM BongoShaftsbury: states
05:42 AM Emil: then OSHPark and PCBWay do deliver very quickly if you pay for it
05:42 AM Emil: Charles just uploaded a video where he got his pcbs in 108 hours
05:42 AM daey: but even fast delivery will cut it close if they only have 7days time
05:42 AM Emil: from PCBWay
05:43 AM Emil: (Charles = CNLOhr)
05:43 AM Emil: daey: true
05:43 AM Emil: that's why I said if they have a bit more time
05:43 AM Emil: but BongoShaftsbury
05:43 AM Emil: matey
05:43 AM Emil: just list the fucking things you have on your list :D
05:44 AM BongoShaftsbury: maybe i'll build a bit coin miner
05:44 AM Emil: I mean sure
05:44 AM Emil: easy as fuck
05:44 AM Emil: "kind of"
05:44 AM Emil: but it has a good amount of buzz in it
05:46 AM daey: implementing a bitcoin miner on an atx is "easy as fuck"? o.0
05:47 AM BongoShaftsbury: maybe connect to wifi and order a pizza from dominos through wifi
05:47 AM BongoShaftsbury: with the press of a push button
05:48 AM Emil: daey: it's only about code
05:48 AM BongoShaftsbury: need a wireless tranciever
05:48 AM Emil: BongoShaftsbury: esp8266
05:48 AM daey: Emil: well ive no backend btc knowledge so its a black box for me.
05:48 AM Emil: daey: you only need to port the algorithm
05:49 AM Emil: daey: and handle the data
05:49 AM daey: and make sure it runs on a tiny amount of ram
05:49 AM Emil: BongoShaftsbury: that sounds like an okay project
05:49 AM Emil: daey: yup
05:49 AM BongoShaftsbury: bitcoin or pizza
05:49 AM Emil: pizza
05:49 AM daey: food always wins
05:49 AM Emil: and it's a better project, too
05:50 AM Emil: though
05:50 AM Emil: you don't need the avr for it :D
05:50 AM Emil: just an esp8266 can do it for you
05:50 AM BongoShaftsbury: i just hope it doesn't send an order for like 5000 pizzas
05:50 AM Emil: unless dominos uses some convoluted api
05:50 AM daey: BongoShaftsbury: do you have to write the code yourself?
05:50 AM Emil: BongoShaftsbury: that's a problem you need to solve
05:50 AM BongoShaftsbury: i have to do everything myself
05:51 AM daey: because writing the whole tcp/ip stack + esp8266 driver isnt going to happen in one week (if you can do it at all)
05:51 AM Emil: daey: mateyy
05:51 AM Emil: daey: the esp handles the tcp/ip stack
05:52 AM Emil: "I have to do everything myself" does not mean he has to write the io headers or cannot use standard libs
05:52 AM BongoShaftsbury: it means my team mates won't help me
05:52 AM BongoShaftsbury: that's how i mean it
05:53 AM BongoShaftsbury: my original idea was to get a software defind radio and set up a base station for cell phones that integrated with an SIP
05:55 AM Emil: :DD
05:55 AM Emil: using an avr?
05:56 AM BongoShaftsbury: yes
05:57 AM BongoShaftsbury: and a dell poweredge
05:57 AM Emil: gg;gl
05:57 AM BongoShaftsbury: lol
05:57 AM BongoShaftsbury: it's unrealistic interesting
06:01 AM BongoShaftsbury: you guys have any cool project ideas
06:03 AM daey: there are things that you can do on an AVR and there are things an AVR is the right tool for.
06:04 AM daey: if the avr is the main processor in the project the later limits you to low power/mobile stuff imho. mining bitcoins on an atmega is stupid
06:05 AM daey: have you looked at the RC field? maybe a rudimentary flight computer for a quadcopter. "orientation only"
06:05 AM tpw_rules: daey: i saw someone who mined bitcoins by hand
06:05 AM tpw_rules: same dude also used an IBM 360
06:06 AM tpw_rules: tbh i wonder if mining bitcoins on an atmega will give you better returns than the lottery
06:06 AM BongoShaftsbury: no
06:06 AM BongoShaftsbury: it's at the point where you need a large commercial undertaking to be profitable
06:07 AM tpw_rules: i mean yeah
06:07 AM tpw_rules: but nobody wins at the lottery either
06:07 AM daey: BongoShaftsbury: if you are lucky you might snack a block :P
06:07 AM BongoShaftsbury: mining below a certain hash rate per power consumption will put you in the red
06:07 AM tpw_rules: same with the lottery
06:07 AM daey: BongoShaftsbury: you are averaging
06:07 AM tpw_rules: i figure there's some finite chance the first hash you try will win you a block
06:07 AM tpw_rules: and how does that compare to winning the powerball or something
06:08 AM BongoShaftsbury: how would i do a flight computer?
06:08 AM BongoShaftsbury: a magnetometer for orientation + 4 gyroscopes?
06:08 AM daey: sensors. filters. atmega
06:09 AM daey: a proejct of that size would at least give you the chance of producing a board, writing the code and documenting it
06:10 AM daey: most teams will likely end up with a shitty looking result hold together by wires
06:10 AM daey: no documentation
06:11 AM daey: the only thing they will learn is that the real amount of work was much larger than the estimated one :p
06:11 AM daey: assuming you really have only 7days to complete the project
06:11 AM BongoShaftsbury: well let's assume that just in case i'm wrong about the extention
06:44 AM daey: tbf. ive got the same problem. i want to do a nice project, ive got the equipment. but theres nothing that is worth doing :D
07:21 AM Lambda_Aurigae: custom gaming controllers are always fun.
07:21 AM Lambda_Aurigae: specially flight controllers.
07:21 AM Lambda_Aurigae: ksp is always a good game to make custom controllers for.
07:21 AM Lambda_Aurigae: x-plane also.
07:22 AM Lambda_Aurigae: I've heard of people using x-plane as a platform for testing quadcopter autopilots too....built it in hardware, connect it to x-plane to test so you don't destroy your hardware.
07:23 AM Lambda_Aurigae: anyhoo..off to werky.
07:24 AM Emil: HAH
07:24 AM Emil: I might have figured out a way to do live streaming without relying on a javascript block
07:24 AM Emil: It's mighty inefficient
07:24 AM Emil: but it werks
07:33 AM Emil: hmm
07:34 AM Emil: by "inefficient" here
07:34 AM Emil: I mean it takes quite a lot of bandwidth
09:20 AM Lambda_Aurigae: camserv works well for me.
09:23 AM rue_house: motion tracking?
09:25 AM Lambda_Aurigae: motion works for that..
09:27 AM Emil: camserv solutions?
09:31 AM Lambda_Aurigae: camserv is a program that does live streaming from a v4l camera.
09:31 AM Lambda_Aurigae: no javascript required.
09:35 AM Emil: ...
09:35 AM Emil: Point is to view the stream on a browser
09:45 AM Lambda_Aurigae: yup.
09:46 AM Lambda_Aurigae: http://cserv.sourceforge.net/
09:47 AM Lambda_Aurigae: aaand, it requires javascript for explorer.
09:47 AM Lambda_Aurigae: oh well.
09:47 AM Lambda_Aurigae: chrome and firefox work without javascript.
10:09 AM Emil: https://www.systutorials.com/docs/linux/man/2-memfd_create/
10:09 AM Emil: This is nice
10:13 AM Lambda_Aurigae: interesting.
10:13 AM Lambda_Aurigae: like a ramdrive for a single file.
10:17 AM cehteh: Emil: i thought more about a real file .. aka 'the portable way'
10:17 AM cehteh: create tmpfile and unlink it immediately
10:18 AM cehteh: usually the kernel takes the hint and keeps it in ram, but it may become paged out when memory gets low
11:00 AM NoHitWonder^: this seems like a pretty cool chip www.mouser.com/ds/2/268/Atmel-8387-8-and16-bit-AVR-Microcontroller-XMEGA-A-1065905.pdf
11:00 AM NoHitWonder^: and only 2,5 bucks
11:00 AM NoHitWonder^: a bargain
11:01 AM LeoNerd: The xmegas generally are quite nice yes
11:01 AM LeoNerd: Bit bigger and fancier than the ATmegas
11:01 AM NoHitWonder^: ive never used one
11:02 AM LeoNerd: But a lot neater and more orthogonal
11:27 AM Lambda_Aurigae: lot more functionality...more complex...requires a PDI programmer
11:28 AM NoHitWonder^: what?
11:28 AM LeoNerd: Huh, I thought xmegas still did SPI-shaped ISP?
11:29 AM Lambda_Aurigae: far as I know they require PDI
11:32 AM LeoNerd: Or JTAG, if you fancy using lots of signal wires :)
11:34 AM NoHitWonder^: well im glad that i have atmel-ice
11:46 AM Emil: http://0hn0.com/
11:46 AM Emil: http://0hh1.com/
12:03 PM Lambda_Aurigae: page 55, section 31...PDI programming
12:03 PM Lambda_Aurigae: no jtag either
12:04 PM Lambda_Aurigae: debugging is also done through PDI. Programming and Debugging Interface
12:04 PM LeoNerd: Prettysure the xmegas all have JTAG
12:04 PM Lambda_Aurigae: page 332...removed JTAG references from datasheet
12:05 PM LeoNerd: Huhh... :/
12:05 PM LeoNerd: That's upsetting.. JTAG is useful for other things besides programming
12:05 PM Lambda_Aurigae: unless it is in a supplemental sheet somewhere
12:05 PM Lambda_Aurigae: no place else in the datasheet mentions jtag
12:05 PM LeoNerd: Boo
12:05 PM Tom_itx: pic avr
12:05 PM Tom_itx: it's the new thang
12:05 PM Lambda_Aurigae: that's the attiny817
12:09 PM Emil: Waaait
12:09 PM Emil: Did my font change
12:12 PM NoHitWonder^: that flippy bit is kinda fun
01:19 PM hetii: Hi :)
01:24 PM NoHitWonder^: hi
01:31 PM Emil: Hola
01:50 PM Lambda_Aurigae: ebola
01:58 PM Emil: NoHitWonder^: you werent joking
01:58 PM NoHitWonder^: wha?
01:59 PM NoHitWonder^: flippy bit?
02:00 PM Emil: yeah
02:00 PM Emil: 26 highscore atm
02:01 PM Emil: Gah
02:02 PM Emil: No wait, 30
02:04 PM Emil: I can do binary to decimal easily
02:05 PM Emil: but binary to A-F is hard
02:11 PM cehteh: a-f?
02:12 PM Emil: nibbles to a-f
02:12 PM Emil: nibbles to 0-9 is easy afg
02:12 PM cehteh: int to hex?
02:13 PM cehteh: int nibble=12; printf("%c", "0123456789ABCDEF"[nibble])
02:14 PM Emil: ...
02:14 PM Emil: MATEY
02:14 PM Emil: context :D
02:14 PM cehteh: lost it
02:14 PM Emil: look abover
02:14 PM cehteh: okok .. busy with something else
02:16 PM * CORDIC prefers asm over C.

03:26 PM Casper: CORDIC: We see... We see it all... you are the masochist kind!
04:06 PM hetii: How do you think, Can I use bss138 as voltage translator from 1v8 to 5v or 3v3 for I2S bus?
04:07 PM hetii: or it will be to slow?
04:08 PM LeoNerd: Do you mean I²C ?
04:10 PM hetii: No, mean I2S, I wonder if this DAC will be able to talk with odroid XU4 I2S bus that operate on 1v8,
05:25 PM Emil: Possibly
05:26 PM Emil: You mean from odroid i2s bus, which is 1.8v, to 3.3v?

05:33 PM Emil: If you can work around the inversion in code
05:33 PM Emil: you need only a signle stage
05:34 PM NoHitWonder^: he's long gone :D
05:34 PM Emil: if you use two stages but have a higher voltage available (like 9v) you should use that to drive the second stage
05:34 PM Emil: NoHitWonder^: Eh
05:34 PM Emil: He might be her
05:34 PM Emil: also backlog :D
05:35 PM Emil: but true, I'm like an hour late
07:38 PM mark4: so im workin on this project where the guy im working for is making coding decisions for me such as defining variable names that I have to write the code around and speicifying -std=gnu++11 being required.
07:38 PM mark4: i already wrote code in C not c++ and you cant use that standard unless you are writing c++
07:39 PM mark4: i tried renaming all my .c source files to .cpp and building but that tells me undefined ref to main at link time
07:39 PM mark4: wtf?
07:39 PM mark4: i will NOT be doing c++ object obfuscated garbage
07:58 PM rue_shop3: good show
08:01 PM mark4: ok i was going to ask "how do i solve this" i figured it out. the solution = -std=c99 and fuck him :P
08:01 PM mark4: brb

11:53 PM rue_house: whats the double inverter for?
11:54 PM rue_house: Emil, to ascii?
11:56 PM rue_house: A = (H&0x0F)>9?(H&0x0F)+0x34:(H&0x0F)+0x30;
11:56 PM rue_house: iirc
