[05:40:28] <inflex> lo folks
[05:40:45] <inflex> amee2k: whatpackage? I've got plenty of SOT-23 suggestions
[05:41:12] * inflex uses FDN303, 337, 2N2007's (or is that 7002), and I love the new PVM16XN's
[05:43:57] <amee2k> inflex: leaded package, and it has to be either logic level voltage type, or any p-channel type
[05:44:36] <amee2k> that'd pretty muc limit it to to92 or to220. noone uses to18 anymore i think
[05:46:07] <amee2k> inflex: FDN30x looks good but i don't see any leaded packages?
[05:54:03] <inflex> oh hell man... leaded ones in small sizes... forget it
[05:55:28] <amee2k> inflex: doesn't need to be small. right now any type will do >_<
[05:56:30] <amee2k> doesn't have to be stellar specs so older types will be fine too. availability and low price is important, and to a degree popularity as well
[06:09:08] <inflex> well, IRF540 or 940 I think
[06:09:11] <inflex> but they're TO220's
[06:09:18] <inflex> plenty of BUZ types
[06:10:39] <amee2k> inflex: irf5x0 is n-channel, not p-ch
[06:52:09] <dunz0r> inflex: IRF540 is N-channel, it's matching P-channel is IRF9540
[08:16:49] <RikusW> specing: http://imageshack.us/photo/my-images/807/dsc0039om.jpg/ :-D
[08:17:04] * RikusW on a bull :-P
[09:07:26] <rue_house> amee2k, in a to-92?
[09:08:10] <amee2k> rue_house: preferably
[09:08:26] <rue_house> 1n7000 ?
[09:08:31] <rue_house> or was it 5000
[09:08:33] <amee2k> any leaded (i.e. thru-hole!) package will do
[09:08:44] <amee2k> 7000 and 7002 are n-channel
[09:08:58] <rue_house> dk just mailed me last week and said the dip8 complimentrary pair I buy is obsolete
[09:09:29] <rue_house> iirc the to-92's are like .3A
[09:09:48] <amee2k> and people say it is very similar to bs170, which means it sucks at logic level voltages (5V barely works, but any lower is not guaranteed to work at all as per ds specs)
[09:10:48] <rue_house> 785-1140-5-ND
[09:10:52] <amee2k> so noone know something that would be accurately described as a generic p-ch mosfet?
[09:11:40] <rue_house> logic level complimentrary pair, ~6A
[09:11:46] <rue_house> 8 pin dip
[09:12:35] <amee2k> mmh, was that a suggestion for me?
[09:12:39] <rue_house> completely obsolete, perfect for small project motor drivers
[09:12:43] <rue_house> yes
[09:12:50] <rue_house> but you cant get it from dk
[09:12:59] <amee2k> oh, i'm looking for singles
[09:13:11] <rue_house> what current?
[09:13:22] <amee2k> i'm writing a reference article for mitx and i'm desperately short on type numbers
[09:13:42] <amee2k> <<300mA
[09:14:09] <amee2k> i'm missing "generic" p-ch mosfets as well as super low voltage mosfets of any type
[09:14:42] <amee2k> hmm does ZPV2106 ring a bell with anyone?
[09:14:57] <rue_house> http://www.digikey.ca/product-detail/en/ZVP2106A/ZVP2106A-ND/92616
[09:14:58] <rue_house> ?
[09:14:58] <amee2k> just found it, and wondering if it would qualify as a common type
[09:15:18] <amee2k> for the protocol, i'm distinctly NOT interrested in buying any either way
[09:15:39] <rue_house> I dont think you can in common, P channel, thruhole, and logic level dont mix for generic
[09:16:11] <amee2k> do "generic" and "thruhole p-channel" mix?
[09:17:12] <rue_house> http://www.digikey.ca/product-detail/en/2SJ377%28Q%29/2SJ377Q-ND/2063137
[09:17:14] <rue_house> getting closer
[09:17:58] <amee2k> 2SJ377 would quality as common generic?
[09:18:38] <rue_house> uh-ho the wikipedia is absorbing semiconductor part numbers
[09:18:53] <rue_house> http://en.wikipedia.org/wiki/2N7000
[09:19:21] <rue_house> The BS250P is "a good p-channel analog of the 2N7000
[09:19:25] <rue_house> ""
[09:19:51] <amee2k> ooh cool
[09:19:56] * amee2k checks out
[09:20:47] <amee2k> that one looks cool, thanks!
[09:21:30] <karlp> fairchild makes plenty in to-220 and dpak?
[09:24:27] <rue_house> http://hades.mech.northwestern.edu/index.php/Driving_using_a_single_MOSFET
[09:24:32] <rue_house> ahahahah I love the heatsink clip!
[10:08:16] <specing> RikusW: That is a bull?
[10:08:35] <specing> Where are his horns?
[10:31:51] <RikusW> specing: he don't have any
[10:32:00] <RikusW> he is young, like 3 years
[10:32:33] <RikusW> and not all cattle have horns
[10:52:23] <RikusW> Hi Steffanx
[10:52:29] * RikusW on a bull http://imageshack.us/photo/my-images/807/dsc0039om.jpg/
[10:53:52] <RikusW> bbl
[10:58:05] <amee2k> this bull is not red
[10:58:10] * amee2k nods meaningfully
[12:12:27] <Steffanx> that is RikusW ?
[12:12:41] <Steffanx> on a ...
[12:25:32] <RikusW> Steffanx: on a young bull :-P
[12:28:14] <Steffanx> You like to play with wild animals? :P
[12:28:54] <RikusW> He isn't wild ;)
[12:29:22] <RikusW> The other cows are....
[12:41:15] <RikusW> Steffanx: Feeling you going to a rodeo ? ;)
[12:41:42] <Steffanx> No, not really
[12:42:08] <Steffanx> but I'm now going to update apache, which is also sort of a rodeo :P
[12:42:54] <Tom_itx> rodeo!
[12:43:51] <Landon> Tom_itx: catch any of the weather this weekend?
[12:44:39] <RikusW> There is 'n tame cow here that once got onto my back.... :-D
[12:44:45] <Tom_itx> south east part of the city got it pretty good
[12:44:45] <Steffanx> So wish me luck
[12:44:49] <Tom_itx> EF4
[12:45:01] <RikusW> They do it when in heat...
[12:45:06] <Tom_itx> i saw some of the damage but apparently i didn't see the worst
[12:45:13] <Steffanx> And you liked it didn't you RikusW ? :P
[12:45:19] <Tom_itx> some trees 4 - 5' diameter pulled up by the roots
[12:45:26] <RikusW> A cow is heavy....
[12:45:30] <Landon> wow, I didn't see the rating or any of the damage
[12:45:51] <Tom_itx> there were 97 tornado's reported in Ks on saturday
[12:46:00] <Tom_itx> last year there were 57 all year
[12:46:01] <Steffanx> 97 :S
[12:46:02] <Landon> the most I got around haysville was some thunder
[12:46:16] <OndraSter> hmm are there any transformers like this on mouser?
[12:46:17] <OndraSter> http://www.gme.cz/ei-transformatory-do-dps/ei-transformator-do-dps-trhei019-1x6v-p610-884/
[12:46:18] <Tom_itx> it started between haysville and us
[12:46:23] <OndraSter> about 2VA, this "cool looking" box
[12:46:26] <OndraSter> into PCBs
[12:46:27] <Tom_itx> spirit got it bad
[12:46:31] <Steffanx> I'm happy mother nature plays over their with her powers and not here :)
[12:46:36] <OndraSter> and about 1.5€
[12:46:44] <Tom_itx> Spirit = aircraft plant for the ones that don't know
[12:46:45] <Landon> yeah, I had some friends working that shift posting pictures from a tunnel they were in
[12:47:05] <Steffanx> *over there
[12:47:14] <Tom_itx> everybody had to stay at intrust arena after the concert was over :)
[12:47:59] <Tom_itx> i saw a business right across from Boeing that had 2 sides of one large metal building caved in and the roof collapsed
[12:49:05] <Tom_itx> basically the same path as the 91 tornado but not as long a path
[12:49:34] * Landon would have been living in colorado back then
[12:49:54] <Tom_itx> you should read about it online
[12:49:57] <Tom_itx> it was a doozie
[12:50:00] <Tom_itx> ef5
[12:50:12] <Tom_itx> covered 46 miles
[12:50:19] <Tom_itx> between haysville and andover
[12:50:24] <Landon> wow
[12:51:04] <Tom_itx> it got boeing then too
[12:51:04] <Tom_itx> a bit
[12:54:46] <Landon> heh, so the 91 tornado is where the whole highway overpass thing came from
[12:54:58] <Tom_L> ?
[12:55:07] <Landon> about taking shelter under an overpass
[12:55:28] <Tom_itx> oh
[12:55:41] <Landon> This belief is partly inspired by widely-circulated video captured during the 1991 tornado outbreak near Andover, Kansas, where a news crew and several other people take shelter under an overpass
[12:56:15] <RikusW> does it actually help ?
[12:56:16] <Landon> not in the least
[12:56:25] <Landon> winds get accelerated even more in a direct hit
[12:56:42] <Tom_itx> the air gets compressed going under the bridge and will suck you right out
[12:56:57] <Tom_itx> and take you on a ride you'll never forget
[12:57:09] <xorm_> or possibly forget on impact?
[12:58:01] <Tom_itx> http://www.kake.com/home/headlines/Red_Cross_Providing_Immediate_Needs_to_Affected_Families_147610625.html
[12:58:12] <Tom_itx> there should be a video there of spirit etc
[12:58:47] <Tom_itx> from that news's helo
[13:05:22] <Landon> Tom_itx: do you know anything about Aeroflex? headed there in a little bit to sign my time away
[13:05:34] <Tom_itx> nope
[13:05:45] <Tom_itx> what do they do?
[13:06:04] <Landon> test instrumentation
[13:06:20] <Landon> at least, the one in wichita
[13:06:54] <Tom_itx> i've probably been by their place but wouldn't know it
[13:09:29] <Tom_itx> abcminiuser you around?
[13:09:41] <Tom_itx> i've got an ubuntu issue
[13:10:09] <vectory> lol, who hasnt
[13:10:13] <Tom_itx> heh
[13:10:27] <Tom_itx> i need to find the file to set php execute permissions
[13:10:50] <Tom_itx> and i don't know linux well enough yet to find it
[13:10:52] <vectory> in apache?
[13:10:59] <Tom_itx> probably
[13:11:09] <vectory> hm, probably isnt good enough
[13:11:21] <vectory> do you perhaps mean /etc/passwd to set a user to a group
[13:11:27] <Tom_itx> i don't recall doing that in debian but i may have
[13:11:31] <Tom_itx> no
[13:11:41] <Tom_itx> it's a share permission i think
[13:12:38] <Tom_itx> you click on an 'index.php' file and it tries to save it instead of display it
[13:13:46] <RikusW> php must go through apache to execute
[13:13:50] <Steffanx> me still wonders what the error logs says
[13:14:10] <RikusW> can't be opened directly
[13:14:23] <Steffanx> It can
[13:14:27] <Steffanx> When apache fails
[13:16:46] <Tom_itx> Steffanx, where's the log at?
[13:17:02] <Landon> do you have php5.conf in /etc/apache2/mods-enabled/ ?
[13:17:05] <Steffanx> /var/log/apache2/error.log
[13:18:04] <Tom_itx> crap, i don't have xchat set up on it now
[13:27:54] <atom1> File does not exist: /htdocs
[13:30:21] <atom1> Steffanx,
[13:30:23] <atom1> [Sun Apr 15 18:14:11 2012] [notice] Apache/2.2.14 (Ubuntu) PHP/5.3.2-1ubuntu4.14 with Suhosin-Patch configured -- resuming normal operations
[13:30:24] <atom1> [Sun Apr 15 19:26:21 2012] [error] [client 68.102.193.26] File does not exist: /htdocs
[13:30:42] <Steffanx> Yay, useful :)
[13:32:15] <atom1> what's it lookin for though?
[13:33:11] <abcminiuser> Tom_itx, yup
[13:33:44] <Tom_itx> abcminiuser, any idea?
[13:36:05] <RikusW> isn't there a php plugin for apache that must be installed too ?
[13:36:36] <atom1> i installed php5
[13:36:41] <atom1> i dunno about the rest
[13:38:06] <atom1> i'm sure it's something really simple but i dunno what
[13:38:37] <atom1> ubuntu website had something about the error and i did that but it didn't fix it
[13:39:09] <atom1> it's probably just some permission i need to set but i haven't found it yet
[13:40:04] <vectory> atom1: erm, mod_php???
[13:40:10] <vectory> dont ask me where to set that though
[13:45:22] <RikusW> I use http://127.0.0.1 for toying with php
[13:45:51] <RikusW> and have installed -> libapache2-mod-php5
[13:46:03] <RikusW> (though that might be a bit old ;) )
[13:47:28] <RikusW> no messing with htdoc over here
[13:47:58] <atom1> RikusW, i think i installed that
[13:48:18] <abcminiuser_> Tom_itx, not a PHP expert
[13:48:25] <RikusW> an then setup your webpage dir too
[13:48:25] <abcminiuser_> But you need to config your webserver to use it
[13:48:32] <atom1> it's ok, i'm just messin with it anyway
[13:48:45] <atom1> i know but i've forgotten how i did it
[13:50:25] <atom1> i'll work on it later today...
[13:51:40] <atom1> i wonder if it's something like a server side include
[13:51:42] <RikusW> oh yes, I've put my stuff in /var/www and a soft link to my home dir
[13:52:22] <RikusW> something like that
[13:52:33] <RikusW> apache executes it
[13:52:37] <RikusW> using the plugin
[13:52:53] <Tom_itx> well, i've got one working that i can look at
[13:55:20] <Tom_itx> oh, no i don't use that
[14:00:11] <karlp> something in your 000-default or whatever else you have in /etc/apache/sites-enabled has a bad path in it,
[15:27:58] <budwaa> Hi, I am trying to write a bootloader but I am struggling to find information about how to get the address for the flash to use with the avr/boot.h functions. Should a function such as boot_page_erase be passed a page address or a byte address?
[15:28:56] <budwaa> So if I have a 64k flash with 256 256Byte pages. Would I pass 0,1,2,3,4...255 or 0, 256, 512, 768, 1024 for the page addresses?
