#emc | Logs for 2004-11-20

[00:03:34] <jepler> good morning people
[00:04:23] <jepler> gave bdi a try on my laptop last night .. I was able to run emc, but I wasn't able to work on getting rs274py running because (no surprise here) it doesn't work with my wireless network card
[00:07:45] <cradek> darn
[00:07:54] <cradek> want to borrow my memory stick thing?
[00:11:40] <jepler> cradek: I can plug it into my wired network, I was just too lazy last night
[00:16:03] <alex_joni> jepler: rs274py needs a net connection to run ? :)
[00:21:40] <alex_joni> jepler: Prism 2.5 chip?
[00:21:45] <alex_joni> on the wifi?
[00:36:43] <jepler> alex_joni: ipw2200 actually
[00:37:18] <jepler> alex_joni: I could have copied the files from my hard drive, but some required packages aren't there and I had hoped to apt-get them
[00:45:56] <alex_joni> hmmm... any new drivers around for the ipw?
[00:46:15] <alex_joni> I know only of the 20$ version
[00:46:39] <jepler> the driver from ipw2200.sf.net works for me, and it's free.
[00:47:37] <alex_joni> does it run on 2.4?
[00:47:48] <jepler> I don't know. I have only used fedora core with kernel 2.6.
[00:47:59] <jepler> apparently not
[00:48:02] <alex_joni> anyways... thx for the link
[00:48:03] <jepler> In order to use the IPW2200 driver you will need the following:
[00:48:04] <jepler> 1. Linux (of course) with a 2.6.4+ kernel
[00:48:12] <alex_joni> that's why I asked
[00:48:34] <alex_joni> :(
[00:48:34] <alex_joni> KERNEL REQUIREMENTS - 2.6
[00:48:35] <alex_joni> --------- ------ ---- --- -- -- - -
[00:48:35] <alex_joni> This driver is currently a 2.6 only driver. Due to time
[00:48:35] <alex_joni> constraints, we can not maintain a 2.4 backport of the driver.
[00:48:35] <alex_joni> If you would like to assist in this and maintain 2.4 backports,
[00:48:37] <alex_joni> please let us know.
[00:50:52] <alex_joni> well... when EMC runs on 2.6 ... maybe :)
[00:54:03] <jepler> so it looks like you're either porting ipw2200 or emc to 2.6 .. get to work!
[00:54:32] <alex_joni> ipw2200 to 2.4
[00:54:36] <alex_joni> or emc to 2.6
[00:54:40] <alex_joni> hmmm.. let me think
[00:54:45] <jepler> er, right
[00:54:56] <alex_joni> I guess I'll use my SMC Cardbus (Prism 2.5)
[00:54:57] <jepler> I suspect porting emc to 2.6 would be time better spent
[00:55:17] <alex_joni> don't want to take the pleasure away from paul...
[00:55:22] <alex_joni> I saw he started
[00:58:17] <alex_joni> anyways... don't know nothing about 2.6... so ...
[01:05:03] <paul_c> * paul_c had emc2 partially compiled under 2.6
[01:05:13] <alex_joni> jepler: see...
[01:05:33] <alex_joni> paul: far from success?
[01:05:40] <alex_joni> or otherwise put: many changes ?
[01:06:25] <paul_c> Not at the time...
[01:07:35] <alex_joni> can it be fixed without ifdef's ?
[01:08:01] <alex_joni> like in emc1 #ifdef KERNEL_VER>2.4 #include <foo.h>
[01:09:44] <paul_c> very little if any ifdefs required.
[01:10:09] <alex_joni> cool... then it could get merged back to HEAD...
[01:28:50] <paul_c> It could if I had committed all the work...
[01:30:49] <alex_joni> but you didn't ?
[01:31:04] <alex_joni> hmmm... let me gues... lost it all ?
[01:41:23] <alex_joni> I'm gone... bye
[04:54:47] <les_away> hmm
[04:54:57] <les_away> I am not away...
[04:55:46] <pfred1_> les next time try /nick les
[04:56:03] <les> ha...ok
[04:56:22] <les> I did not even do a nick change
[04:56:26] <les> oh well
[04:56:48] <pfred1_> well well well Steve Ballmer is going to sue all of us Linux users now http://www.cnn.com/2004/TECH/biztech/11/19/tech.microsoft.linux3.reut/index.html
[04:57:19] <pfred1_> man i need a .47 uF polyester capacitor
[04:57:27] <pfred1_> anyone got one handy? :)
[04:59:03] <les> sure...right in the parts drawer....should I email it?
[04:59:06] <les> haha
[04:59:41] <pfred1_> on the lighter side ever since the CIA has taken control of Afghanistan heroin production is booming! http://www.cnn.com/2004/WORLD/asiapcf/11/19/afghan.opium.ap/index.html
[04:59:53] <pfred1_> so I guess it all balances out
[04:59:58] <les> bypass cap for ic?
[05:00:11] <pfred1_> nah it's for a preamplifier
[05:00:21] <les> audio?
[05:00:30] <pfred1_> making a new guitar amp I'm not quite deaf enough yet
[05:00:51] <les> I just use an old fender 30
[05:01:13] <pfred1_> I have an old fender tube amp but it's dead and I well tubes are a thing of the past
[05:01:22] <les> It was the only fender with williamson ultra linear circuit
[05:01:31] <pfred1_> my transistor amps sound nice enough to me
[05:01:37] <les> so sounds a bit different
[05:02:17] <les> well I have several kW of solid state so I like em too
[05:02:46] <pfred1_> yeah the "warmth of tubes" is a bit of a myth except in a thermal sense
[05:02:56] <les> had to work on one last night
[05:03:02] <pfred1_> transistor amps can be "warm" too :)
[05:03:10] <les> an Alesis Matica
[05:03:25] <les> 1350 Wrms bridged
[05:03:38] <pfred1_> yeah what was wrong with it?
[05:03:49] <les> the protection circuit has a relay that is going I thing
[05:04:10] <pfred1_> yeah I think they put relays into amps to stop speaker pop on power up too
[05:04:20] <les> some times shuts down....but tap the relay and it comes back on
[05:04:30] <les> this runs the servo fan
[05:04:30] <pfred1_> cold solder joint?
[05:04:53] <les> joints LOOK ok...real solid
[05:05:54] <les> Mouser has the relays for $2.50...I'll just order the and perhaps reflow the joints while the fan control board is out
[05:06:21] <les> 30 amp relays
[05:06:45] <les> It's a good amp...real clean
[05:07:10] <les> fan speeds up when you crank it...servo controlled.
[05:07:51] <les> The thing drives two McCauley 15s below 80 Hz in the music room
[05:08:19] <pfred1_> and i thought i was rocking over here with my old samsung
[05:08:46] <les> I designed a quad ampped system
[05:10:21] <les> The crossover is Linkwitz Reilly fourth order using the Burr-Brown OP 604
[05:10:34] <pfred1_> woo burr browns are nice
[05:10:37] <les> about the best op amp for audio I have found
[05:10:46] <les> cheap too
[05:11:01] <pfred1_> they're not that cheap in the world of op amps
[05:11:08] <pfred1_> but they are reasonable
[05:11:46] <les> well not like the .08 I pay for the 2902 quad in that sensor we are manufacturing
[05:11:55] <les> but a buck or two
[05:12:15] <pfred1_> where you usually get your parts from?
[05:12:41] <les> At unity gain I was never able to measure ANY distortion
[05:12:48] <les> digi key usually
[05:13:56] <les> for the aforementioned stuff I used metal film resistors and hand trimmed pp caps
[05:14:23] <pfred1_> yeah metal film so much better than carbon IMO
[05:14:51] <les> you know...grind them down from the top then clear em by plugging them in a wall socket
[05:16:02] <les> We have a capacitor division (Paktron) and they do just that when they need a quick custom value
[05:17:43] <les> well ...late lunch for me...back in a while
[07:24:26] <paul_c> drat... Another python bug to track down...
[07:24:40] <jepler> paul_c: what's this python program you're working on?
[07:25:32] <paul_c> anaconda
[07:25:40] <jepler> oh, the redhat installer?
[07:26:04] <jepler> I've never looked at it, despite all my years as both a redhat/fedora user and a python fan
[07:29:16] <jepler> speaking of Python:
[07:29:23] <jepler> >>> import emc
[07:29:23] <jepler> >>> c, s = emc.command(), emc.stat()
[07:29:30] <jepler> >>> c.mdi("g0 x1 y1 z1")
[07:29:44] <jepler> >>> s.poll(); s.actual_position
[07:29:48] <jepler> (1.0, 1.0, 1.0, 0.0, 0.0, 0.0)
[07:30:07] <cradek> jepler: don't give away all our tricks yet
[07:31:17] <jepler> cradek: don't worry, I'm saving the best for when it works...
[07:31:28] <cradek> jepler: good
