[01:02:26] <inflex> hiya Tom_itx
[03:00:05] <jadew> do you guys think this is worth 500 eur? http://www.rigolna.com/products/digital-multimeters/dm3000/dm3058E/
[03:00:13] <jadew> (that's how much it costs in my country)
[05:14:27] <creep> why is it cool to have a relay connected in series with an ssr in a printer fuser control ?:)
[05:27:53] <Horologium> creep, depends what an SSR is..
[05:28:36] <Horologium> if by that you mean a solid state relay, it is likely for safety.
[05:28:58] <creep> that is a solidstate relay with a bcr5pm
[05:29:09] <Horologium> a fuser has the potential to get really really hot and cause a fire.
[05:29:32] <creep> but a good ssr will not die
[05:29:33] <Horologium> usually it has a thermostat in it through which the main heating power goes through.
[05:29:38] <creep> a relay will
[05:29:47] <Horologium> the SSR won't die but the controlling circuitry might.
[05:29:56] <creep> ;/
[05:30:03] <Horologium> they are connected to different temp/control circuits most likely.
[05:30:20] <creep> so how does this help then? the relay is driven by the control circuity too
[05:30:34] <creep> also, there is a 228C thermal fuse in the fuser
[05:31:51] <creep> lold at this fuser, it has some scrap pcb with a track on it for heating
[05:32:05] <Horologium> what is that out of?
[05:32:08] <Horologium> an HP printer?
[05:32:13] <creep> yeah
[05:32:27] <Horologium> I think they PWM the SSR for temp control.
[05:32:36] <creep> possible
[05:32:52] <Horologium> and the relay is for hard power off.
[05:33:08] <creep> but looks like it has 2 temp sensors
[05:33:10] <Horologium> the heater is a piece of nichrome wire embedded in the board.
[05:33:24] <Horologium> very likely does.
[05:33:34] <creep> is that safety too?
[05:33:37] <Horologium> heck, I have some fusers with 5 temp sensors.
[05:33:42] <creep> haha
[05:33:52] <creep> over regulated
[05:34:16] <creep> are they simple ntcs ?
[05:34:18] <Horologium> has 2 sensors on the upper roller, 2 on the lower, and 1 on the preheat roller.
[05:34:33] <Horologium> the temp sensors are thermal resistors...I have a pile of them here.
[05:35:04] <Horologium> also have many of those little can thermal fuses which are often called thermostats in the manuals.
[05:35:16] <creep> oh this is some junk, it has some flexible ptfe or whatever coated fabric sliding around theheater pcb
[05:35:36] <Horologium> that's normal...it's called a fixer sleeve.
[05:35:38] <creep> i was expecting a heater lamp and an aluminium tube
[05:35:52] <Horologium> which is the upper roller technically.
[05:36:04] <Horologium> for that you need older HP or higher speed device.
[05:36:19] <Horologium> get one out of a copier rather than a printer..
[05:36:34] <Horologium> or, like, an HP 5si, 8100, 8150
[05:36:36] <creep> okey
[05:36:41] <Horologium> or 9000 or 9100
[05:36:46] <creep> are the heater lamps ir lamps ?
[05:36:52] <creep> or just simple halogen stuff ?
[05:37:02] <Horologium> halogen gives off IR too.
[05:37:09] <Horologium> they glow but not real bright.
[05:37:25] <creep> yeah, but the quartz tube ir lamp is much better for ir heating
[05:37:41] <Horologium> we threw out about 100 identical lamps a while back at work.
[05:37:52] <creep> ofcourse for theating something from te inside it does not count ;/
[05:38:42] <creep> anyway, i can get ir heaters cheap at tesco corps
[05:40:03] <creep> i was just surprized i found an ssr :)
[05:41:33] <creep> hm, this board is crap, looks like bakelite
[05:42:12] <Horologium> which board?
[05:42:15] <Horologium> the heat strip?
[05:42:33] <creep> the psu board, main board, about the size of an atx mb
[05:42:49] <creep> this has the ssr too
[05:43:37] <creep> str-z2064, 400v150u, 2 double schottky after the ferrite core
[05:43:48] <creep> the filtering is all right too
[06:46:14] <creep> 5A triac, or 2 back 2 back 12A thyristor for zvs controlling 700W ir lamp ?
[06:47:21] <RikusW> I'd say the triac is easier to control ?
[06:47:28] <RikusW> just get a diac too
[06:47:43] <creep> i use optocoupler trigger
[06:47:52] <creep> so no, simple
[06:49:06] <creep> i currently don't have 12-25A triac. this is why i am wondering if it would be nice to give a little more safety
[06:49:35] <RikusW> 110 or 220Vac ?
[06:49:40] <creep> 230V
[06:49:57] <creep> and heaters have low cold resistance...
[06:49:57] <RikusW> 700W ~~ 3A
[06:50:39] <creep> my 5A triac might burn ;<
[06:52:55] <Tom_itx> http://tom-itx.dyndns.org:81/~webpage/toaster_oven/control_sch.png
[06:53:06] <creep> haha you hack toaster ovens too?
[06:53:16] <Tom_itx> ages ago
[06:53:36] <Tom_itx> works like a champ
[06:53:55] <Tom_itx> i used a different triac though
[06:53:59] <creep> yeah i use something similar SSR
[06:54:17] <creep> looks like my best option is to go and get a 25A triac? :(
[06:54:17] <Malinuss> anyone ever used eagle+eagleup+sketchup, to design something?
[06:55:07] <creep> or just the 12A...
[06:55:16] <Tom_itx> Malinuss, i use eagle
[06:55:19] <creep> i use 25A triac for the 1500W hotplate
[06:55:21] <creep> works nice
[06:55:43] <Malinuss> Tom_itx, how did you design your enclosure for your programmer?
[06:55:46] <Tom_itx> you probably didn't even need to heatsink that
[06:55:57] <Malinuss> Tom_itx, as in - what kind of software - if any?
[06:55:59] <Tom_itx> with my cad cam
[06:56:11] <Malinuss> Tom_itx, did you import the pcb from eagle?
[06:56:20] <Malinuss> Tom_itx, and made all the parts etc.
[06:56:25] <Tom_itx> the outline
[06:56:43] <Tom_itx> i bought the enclosure and did the cutouts
[06:57:07] <Malinuss> Tom_itx, I see, thanks. May I ask which cad cam you use?
[06:57:46] <Tom_itx> http://www.youtube.com/watch?v=-CEqokrtFI4&feature=youtu.be
[06:57:51] <Tom_itx> i think that's it
[06:57:55] <Tom_itx> smartcam
[10:06:15] <slidercrank> hdd clock: http://s.pikabu.ru/post_img/2013/02/21/7/1361438482_984851218.jpg
[13:19:40] <amee2woof> how do you make good electrical contact with an aluminium rod? o.O
[13:23:15] <Tom_itx> that paste they use on aluminum wiring
[13:23:56] <GuShH_Lap> amee2woof: screw terminal
[13:24:18] <amee2woof> do i need a minimum pressure for the paste to work?
[13:24:27] <GuShH_Lap> before you get all emo on me, there are aluminum terminals specifically for bonding with copper wiring and they can be seen as screw terminals.
[13:24:40] <GuShH_Lap> some are crimped on, some are screwed on.
[13:24:52] <amee2woof> i've been scratching my head back and forth, but i can't find a good way put a terminal or bracket or similar thing on it
[13:25:10] <GuShH_Lap> is alu wiring common in your country?
[13:25:40] <GuShH_Lap> amee2woof: what is this for? you could kludge it with a hose clamp
[13:25:48] <GuShH_Lap> some are plated which means you can often solder directly to them
[13:25:58] <GuShH_Lap> yey?
[13:26:05] <amee2woof> no, but the hardware store only has the sizes in aluminium, not brass which would be easy to solder
[13:26:26] <amee2woof> hmm the hose clamp actually is an interesting idea
[13:26:27] <GuShH_Lap> pft I like my idea.
[13:26:46] <GuShH_Lap> amee2woof: I've been known to hose-clamp lots of things!
[13:27:18] <GuShH_Lap> I wonder if you could hose clamp a horse.
[13:27:25] <amee2woof> o.O
[13:27:32] <amee2woof> that might need a very large clamp
[13:27:45] <amee2woof> and pissed off horse is not cuddly
[13:27:58] <vsync_> just don't stand behind it
[13:28:16] <GuShH_Lap> I wouldn't even try it
[13:28:39] <vsync_> god damn singapore post website slow again
[13:28:44] <vsync_> they have some issues
[13:28:49] <vsync_> constantly
[13:28:54] <GuShH_Lap> go fix it for them
[13:29:05] <vsync_> i'm no software geek
[13:29:13] <GuShH_Lap> in exchange for lost and found packages
[13:29:27] <vsync_> i do know that much that it's their database timing out
[13:29:29] <GuShH_Lap> you don't have to be a geek, just a dev
[13:29:36] <vsync_> devs are geeks
[13:29:44] <GuShH_Lap> vsync_: poorly written sql is nothing new
[13:29:48] <GuShH_Lap> I'm not a geek
[13:29:49] <vsync_> software geeks, to be spesific
[13:30:08] <GuShH_Lap> to be spesific it's specific
[13:30:25] <GuShH_Lap> so be specific if you want to be specific, don't be spesific while trying to be specific.
[13:30:33] <GuShH_Lap> Brought to you by Motul Specific(tm)
[13:30:48] <vsync_> sowwy, english isn't my native
[13:30:53] <GuShH_Lap> WE LIKE OIL (french dude eating a baguette agrees)
[13:31:32] <GuShH_Lap> why is liqui-moly oil so expensive!
[13:31:41] <vsync_> molly molly molly
[13:32:06] <GuShH_Lap> I must assume moly comes from molybdenum.... but they all have it, at least these specific types.
[13:32:40] <GuShH_Lap> vsync_: maybe it's due to their marketing campaigns that we end up paying high prices?
[13:32:43] <GuShH_Lap> http://px6.streetfire.net/0001/23/46/1923264_600.jpg (maybe nsfw)
[13:32:57] <GuShH_Lap> but who on earth would put top brand oil on that piece of shit car?
[13:33:29] <vsync_> there's some fine moly on that there
[13:33:35] <GuShH_Lap> ok this is definetly NSFW http://www.chromjuwelen.com/g2/d/250431-5/LIQUI+MOLY_06_10.jpg I hope it's not official.
[13:33:37] <vsync_> anyway why do you need that
[13:33:48] <GuShH_Lap> I would rear end that.
[13:33:56] <GuShH_Lap> vsync_: I'm an engine geek
[13:33:58] <vsync_> i'd help her with her molys
[13:34:09] <GuShH_Lap> just not the type that read a book and pretends to be a mechanic.
[13:34:25] <vsync_> just the type that googles "best x" and has to use it?
[13:34:27] <GuShH_Lap> her molys are nice, other aspects aren't
[13:34:33] <GuShH_Lap> no.
[13:34:40] <vsync_> THIS IS THE SHIZ, I SWEARZ
[13:34:46] <GuShH_Lap> they didn't have motul in store and went for liquimoly, now I'm bitching about their prices..
[13:34:58] <GuShH_Lap> motul is also expensive
[13:35:04] <GuShH_Lap> as are most synth oils anyway (not that they don't have mix or minerals...)
[13:35:12] <vsync_> aaand
[13:35:25] <vsync_> just go for run of the mill 0w40
[13:35:33] <GuShH_Lap> liqui has all sorts of additives and to this day I think they're all a lie
[13:35:41] <GuShH_Lap> vsync_: on a shitty old car sure
[13:35:48] <GuShH_Lap> on something you care about, no
[13:35:51] <vsync_> yes
[13:36:59] <GuShH_Lap> amee2woof: on ubuntu the default font is ubuntu, but what about other distros? is there a common font throughout?
[13:38:04] <vsync_> this reminds me of the reason why i left the sparkfun channel
[13:38:15] <vsync_> there was this guy... who had bought some mcus and stuff
[13:38:16] <GuShH_Lap> oh?
[13:38:29] <vsync_> and was about to hook em up
[13:38:32] <GuShH_Lap> do women wear this kind of thing often? http://good-wallpapers.com/wall.php?category=bikes&id=3266&width=1280&ratio=1.25
[13:38:59] <amee2woof> GuShH_Lap: not really
[13:39:05] <GuShH_Lap> I must admit I looked at the bike first, then noticed the dirty fender, then the low resolution, then her.
[13:39:07] <vsync_> so, he's a software nerd. Had apparently googled everything, for best this and that, and "best practises"
[13:39:11] <amee2woof> if you need a specific font, set it explicitly
[13:39:27] <GuShH_Lap> I'm not really a googloid...
[13:39:29] <amee2woof> if not, make the exact font used as uncritical as possible
[13:39:33] <GuShH_Lap> if I don't know about something I don't pretend to
[13:39:41] <vsync_> So then he starts going off on about, using his flux, and how he has this rosin core solder, and is it safe to do this, and that, and how to heat the iron
[13:39:52] <vsync_> He had done this for around 2 hours before he had soldered a single wire
[13:40:05] <GuShH_Lap> sounds like someone from ##electronics
[13:40:07] <vsync_> and the other googloids on that channel, just went along with it. I thought dear god
[13:40:10] <GuShH_Lap> what was his name....
[13:40:14] <GuShH_Lap> I made him rage quit a few times
[13:40:28] <vsync_> Could have been ##electronics though. But I thought it was sparkfun. Well, in any case...
[13:40:36] <GuShH_Lap> he had spent his (I guess) drug money on scopes, reflow stations, etc. didn't even know what a sinewave was.
[13:40:50] <vsync_> well, probably not the same guy then
[13:40:53] <GuShH_Lap> oh yeah now I remember the name.
[13:41:00] <vsync_> ?
[13:41:07] <GuShH_Lap> he's here.
[13:41:31] <vsync_> crap
[13:41:38] <GuShH_Lap> haha
[13:41:43] <vsync_> bad karma
[13:41:47] <GuShH_Lap> why?
[13:41:59] <GuShH_Lap> tandoori knows who he is.. oh, oops.
[13:42:13] * GuShH_Lap idly raises the finger
[13:42:36] <GuShH_Lap> holy crap, firefox is taking 6GB of ram
[13:42:45] <GuShH_Lap> to the panic wagon!
[13:48:31] <GuShH_Lap> amee2woof: just trying to see if there's a common default font, the ideal solution is to find out which the sys default font is and use it instead anyway
[13:49:01] <GuShH_Lap> I can do that in windoze easily, haven't tried on nix
[13:50:01] <GuShH_Lap> (it's through SystemParametersInfo() )
[13:51:31] <amee2woof> GuShH_Lap: in GNOME you should be able to find out the default font through gconf
[13:52:07] <amee2woof> i'd expect KDE to have something similar but i don't use that... also, there might be a convention to alias the default font to something or query the X server
[13:52:55] <GuShH_Lap> it's just the default font face size on ubuntu for example varies and is too big in some cases
[13:53:09] <GuShH_Lap> (that's the only *nix I plan to support for this)
[13:53:41] <GuShH_Lap> labels are bigger than checkboxes...
[13:53:50] <GuShH_Lap> drop-downs are bigger than checkboxes too, for example
[13:54:11] <GuShH_Lap> so I'm forced to obtain the system font and setup a regular size for all controls
[13:54:38] <GuShH_Lap> otherwise some texts are cut out, others look like poop.
[13:55:04] <GuShH_Lap> I should have more space for the labels, assuming some languages may require a lot more realestate to display the same information, but whatever.
[14:25:44] <tandoori> huh? who rang?
[14:26:10] <tandoori> oh lord
[14:26:18] <tandoori> ignore his spread of lies
[14:27:55] <vsync_> drugs are bad mkay
[14:28:48] <tandoori> indeed they are :-P
[15:51:28] <creep> reloaded
[15:52:14] <creep> nah i got a 25A triac, many years of safe operation as an ssr is worth 2 euros

[16:14:54] <Tom_L> arm
[16:16:28] <creep> aha kool
[16:17:23] <creep> so now i can make 5000 dcdc converters on an A4 board

[23:14:03] <rue_house> damn, thats god
[23:14:05] <rue_house> good
[23:14:44] <Casper> no it's not
[23:14:53] <Casper> stop pretending :D
[23:21:31] <theBear> hmm, rue must be eating poutine
[23:21:37] <theBear> or perogies
[23:21:44] <theBear> i wonder... i think all the good stuff from canada starts with p :)
[23:24:47] <rue_house> hah
[23:26:14] <Casper> hmmm poutine...
[23:26:23] <Casper> and I'm hungry...
[23:26:38] <Casper> THEBEAR! BAD BEAR! :'(
[23:26:55] * Casper gets strawberry...
[23:27:11] <rue_house> I'm running out of preselected tings to buy from ebay for $1
[23:27:17] <rue_house> need to get more queued up
[23:28:54] <theBear> i'm good !
[23:28:54] * Casper throws a penny at rue_house
[23:29:13] <theBear> i get older today :-/
[23:29:14] <rue_house> ooo copper!, me cashes it in for 5c of copper
[23:29:26] <Casper> theBear: oh happy bday theBear !
[23:29:26] <theBear> hehe
[23:29:26] <rue_house> theBear, good show!
[23:29:36] <Casper> rue_house: isn't it 2 cents?
[23:29:47] <rue_house> have you seen the prices on copper!?
[23:30:05] <theBear> not for a few years, they going back up ?
[23:30:13] <rue_house> the mint is gonna make a FORTUNE on the returned pennies
[23:30:31] <theBear> ooh, conspiracy theory, they announced taking them out of circulation yet ?
[23:30:34] <Casper> rue_house: http://casper.is-great.org/IMG_0664.JPG
[23:30:49] <rue_house> they did take them out
[23:30:51] <rue_house> just recently
[23:31:03] <rue_house> canada is trying to cope with how to do the books with no pennies
[23:31:22] <rue_house> why did you scan a penny?
[23:31:37] <Casper> rue_house: the other day, a customer was complaining to a cashier at Maxi for how to round the total
[23:31:49] <Casper> they decided to round it down
[23:31:54] <Casper> instead of to the nearest
[23:32:02] <Casper> so the customer is always winning...
[23:32:07] <Casper> ... that idiot was complaining!
[23:32:15] <Casper> rue_house: no, it's a photo I took with my camera :D
[23:32:22] <rue_house> ah
[23:32:53] <rue_house> I can see the atoms if I'm not zoomed out
[23:32:58] <Casper> oh? there is some initials on the penny!
[23:33:44] <Casper> it'S weird... you can actually see the scratch on the dots :D
[23:33:55] <rue_house> yea...
[23:33:56] <theBear> here they made strict rules when we stopped using 1 and 2c coins re: things like rounding
[23:33:59] <rue_house> goodnight
[23:34:06] <theBear> cya :)
[23:34:10] <rue_house> the what do they do?
[23:34:21] <Casper> theBear: they did made rules here, 0-2 = 0, 3-5 = 5
[23:34:43] <Casper> but maxi simply decided to not make the customer pay more, so did 0-4 = 0
[23:35:41] <Casper> rue_house: nice pic isn't it?
[23:35:42] <theBear> i wonder if that's legal, they'd have to be sneaky for sure, like change the invoiced amount or call the extra 'a free tip'
[23:35:52] <theBear> one of my best buddies is called maxi
[23:36:01] <theBear> i call him mr maxi, tho i'm tempted to change it now he's married
[23:36:56] <Casper> to mini?
[23:37:03] <Casper> or mr yesman?
[23:37:28] <Casper> rue_house: http://casper.is-great.org/IMG_0677.JPG
[23:37:56] * Casper wonders if rue_house know what it is :D

[23:41:20] <rue_bed> rrrly?
[23:42:55] <Casper> * Casper wonders if rue_house know what it is :D
[23:43:55] <rue_bed> I give up, its taking toooo long to download
[23:44:01] <rue_bed> maybe use smaller images
[23:45:06] <Casper> lol
[23:45:17] <Casper> what you don't like my 18 megapixels pics? :D
[23:45:41] <rue_bed> no
[23:45:54] <Casper> atleast I didn'T sent you the raw file (about 28 megs!)
[23:45:54] <rue_bed> unless its important 640x480 will do
[23:46:25] <rue_bed> but if you get a chance, take me one of those raw images of the moon
[23:47:28] <theBear> hmm, have to be out of a monitor i say
[23:47:44] <Casper> theBear: my pic?
[23:47:50] <theBear> yup
[23:48:00] <Casper> you're so close
[23:48:09] <Casper> laptop lcd monitor, led based
[23:48:10] <theBear> awww, projector or lappy ?
[23:48:26] <theBear> i like guess the pcb games
[23:48:54] <Casper> I'm actually in the process of hacking it up
[23:48:56] <theBear> i was tempted to lean lappy (honest :) cos of the huge fingered connector
[23:49:11] <theBear> tho i seen similar in more recent projectors too
[23:49:27] <theBear> and i don't see monitors till the caps die, so i'm behind :)
[23:49:37] <Casper> :D
[23:49:52] <Casper> actually, I opened an LG monitor... I was deceived by how it's made
[23:49:54] <Casper> and btw
[23:50:07] <Casper> do you have a trick to open those without damaging the plastic?
[23:50:39] <rue_bed> it just clicked to me how close the lcd pixel bus is to HDMI
[23:50:43] <rue_bed> serial
[23:51:26] <rue_bed> er dvi, sorry
[23:59:21] <theBear> i use various guitar picks on the tricky ones, only one i haven't been able to do 100% undamaged in recent years is err, panasonic or some name brand, it's been opened 10 times now and it's still tricky
