[01:04:08] <skunkworks> stupid question - how do you find an encoder pack for linux. (started to try to reduce the size of the big video.
[01:15:07] <jepler> skunkworks: beats me. on jmk's machine to encode the "time lapse" videos we just used lavc with mpeg4 and as far as I know that was already installed when he installed mencoder
[01:17:20] <jepler> skunkworks: looks like maybe you want w32codecs from the multiverse repository? http://swik.net/Ubuntu/Only+Ubuntu/Install+Mplayer+and+Multimedia+Codecs+(libdvdcss2,w32codecs)+in+Ubuntu+Dapper+Drake,Edgy+Eft,Feisty+Fawn/1y5q
[01:17:48] <jepler> er, strike that -- from deb http://mirror.ubuntulinux.nl dapper-seveas all
[01:18:26] <skunkworks> Than you. Still playing
[01:29:21] <skunkworks> thank you I eman
[01:29:26] <skunkworks> omg
[01:29:27] <skunkworks> thank you
[01:33:15] <skunkworks> http://www.youtube.com/watch?v=vNn-Yr7it5s
[01:34:22] <skunkworks> look ok?
[01:34:45] <DanielFalck> works here
[01:38:42] <skunkworks> anyone remember what size the big ball mill was?
[01:38:54] <skunkworks> the small one was 3/16 iirc
[01:44:31] <jepler> skunkworks: half inch, I think
[01:47:09] <skunkworks> jepler: thanks again..
[01:51:51] <skunkworks> jepler: the encoders fit right on the back of these clinton servos. it even bolts right up.
[01:53:27] <skunkworks> it will be nice to play with. learn
[01:55:40] <cradek> welcome back to the real world everyone
[01:55:55] <skunkworks> cradek: Hi
[01:56:37] <cradek> hi
[01:56:47] <cradek> nice to see you, wish we had been able to get dinner together or something
[01:57:00] <skunkworks> we didn't run over any shreaded tires on the way back. dad clipped the bumper plastic back on this evening. said it went back togather easy.
[01:57:43] <cradek> it feels good to get through 1k miles of driving and not have hit anything...
[01:57:50] <cradek> you had a minor incident?
[01:58:28] <skunkworks> ran over a shreaded semi tire. took the left side of the plastic bumper cover off of the scion
[01:58:42] <cradek> ah
[01:59:18] <cradek> glad it was minor
[01:59:40] <skunkworks> There is always next year. I figured we had annoyed you guys enough :)
[02:00:34] <skunkworks> it was great watching you guys work
[02:01:40] <cradek> I dunno, I watched the webcam video, and it was pretty boring
[02:01:46] <cradek> some funny stuff in there, though
[02:02:05] <DanielFalck> who was the guy who fell asleep at his laptop?
[02:02:15] <skunkworks> I don't really know..
[02:02:33] <cradek> he was a visitor who came from hong kong just for the workshop
[02:02:57] <cradek> unfortunately I didn't get his name
[02:03:29] <DanielFalck> I watched the cat run across the floor too. hope it caught the mouse it was after : )
[02:03:42] <cradek> yeah I think he was getting into our snack food too
[02:03:49] <cradek> ... which is ok, there was plenty
[02:04:01] <skunkworks> There was some keyboard issues with boris also ;)
[02:04:06] <skunkworks> I hear
[02:04:21] <cradek> I didn't see boris in the video - was he in there?
[02:04:31] <DanielFalck> did he walk all over a keyboard that was live on IRC?
[02:04:49] <skunkworks> jkm said he was..
[02:05:00] <skunkworks> I have not looked
[02:06:59] <skunkworks> whoever brought the snacks - thank you.. I
[02:07:39] <cradek> it was fun to watch the pretzel jar go down in the video
[02:07:48] <cradek> (that was swp)
[02:08:57] <skunkworks> Good - he was the one who told me to dig in.. :)
[02:21:00] <skunkworks> 48 views so far on the first tapping video :)
[02:21:21] <skunkworks> 30 of them where me... j/k
[02:22:47] <cradek> heh
[02:23:00] <cradek> I suppose it was better in person
[02:28:12] <skunkworks> it was - but the video is the next best thing..
[02:28:44] <skunkworks> felt like a bit if history was in the making. - ok that was a bit cheesey
[02:28:57] <cradek> haha
[02:29:09] <cradek> it's nice to present a cool new feature every year
[02:29:15] <cradek> (or two or three)
[02:29:29] <cradek> might be hard to keep that record up though
[02:29:45] <cradek> for me, the new lathe features are actually much more useful
[02:29:52] <skunkworks> I bet.
[02:30:07] <skunkworks> that was cool to watch also.
[02:30:17] <cradek> now I have to try to learn how to use them well
[02:30:41] <skunkworks> then the creative tooling was fun too
[02:30:55] <skunkworks> your lathe was a real trooper
[02:43:45] <skunkworks> http://www.electronicsam.com/images/KandT/cncworkshop07/
[02:49:36] <skunkworks> dad didn't take many pictures this year.. I have a few more.
[02:50:52] <cradek> those are nice (and I need a haircut)
[02:54:37] <skunkworks> no pictures of you other than the back of your head :)
[02:56:31] <cradek> that's ok, I bet few came to see my smiling face
[03:00:07] <skunkworks> bah - your the only one that seems to make sense. everyone else doesn't know how to dumb down the conversation. ;)
[03:00:46] <skunkworks> you must have to deal with idiots more..
[03:01:55] <skunkworks> crap - that was supposed to be in a pm ;)
[03:05:08] <cradek> hmmm - I guess I'll take that as a compliment :-)
[03:05:57] <cradek> it's nice to be back to my real computer, real recliner, real air conditioning
[03:06:19] <cradek> also, I'm soon to try out my own bed
[03:06:25] <skunkworks> :) I posted about the breakthrough with emc2 in about 3 different threads on cnczone.
[03:06:34] <cradek> (glad I took an extra day off tomorrow)
[03:06:52] <cradek> that's cool to let people know how it went, thanks for being such a great advocate
[03:07:13] <skunkworks> Yes - I can't wait for that either. And snuggling the significant other. (maybe tmi)
[03:07:24] <skunkworks> It is the least I can do/
[03:07:57] <skunkworks> there was one thread on the fest where someone had taken all the pictures of mach and such.. like that was the only thing going on.
[03:08:15] <skunkworks> He also makes money on mach...
[03:08:30] <cradek> I always intend to go to the mach stuff to see what it's like (I've never used/seen it)
[03:08:52] <skunkworks> I sat in one last year. It was ok
[03:09:26] <cradek> well I've seen the screens, but not what it does
[03:09:48] <cradek> I also wanted to hear whether it works on Fista :-)
[03:11:39] <skunkworks> :)
[03:14:14] <cradek> http://www.artsoftcontrols.com/forum/index.php?topic=2385.0
[03:14:54] <cradek> apparently the answer is "not really"
[03:14:58] <skunkworks> cradek: did you see that the encoder we bought where 2540 line. took until the drive home before it dawned on me why that number sounded familiar
[03:15:38] <skunkworks> yeck
[03:16:13] <cradek> ahh I noticed that right away - whenever I see 25.4 anywhere I jump because I think it's a units bug :-)
[03:17:15] <skunkworks> ;) - they will also bolt right up to some small servos we had also.. be nice to experiment
[03:17:26] <cradek> nice
[03:17:29] <cradek> that's a lot of resolution
[03:17:44] <cradek> they were hard to pass up - but I didn't have a use in mind
[03:18:05] <skunkworks> yes - nice test for the pluto.. - they will only go around 2400 rpm though. but that is more than we will probably run
[03:18:53] <skunkworks> the have a max rate at 100k or 3000 rpm - what ever is first
[03:19:33] <skunkworks> I think I told you that already..
[03:19:47] <cradek> I guess my pluto counts the spindle at about 100kHz
[03:19:57] <cradek> 1500rpm, 4096 counts/rev
[03:20:26] <cradek> I never thread that fast of course (would have to be a very fine pitch)
[03:20:37] <skunkworks> yes
[03:20:42] <cradek> the pluto is a neat little device
[03:20:54] <skunkworks> Yes it is - jepler did a great job
[03:21:27] <cradek> yeah he's clever at that kind of thing
[03:21:34] <cradek> I'm off to bed now! goodnight
[03:21:38] <skunkworks> It is nice to be able to play with servos without worrying too much about destroying the pluto - cheap
[03:21:41] <skunkworks> night - same here
[14:16:43] <skunkworks> alex_joni: what was the issue with the first stg card.. something to do with the index pulse for all axiss only being sent to 2 bits or something like that.
[14:17:34] <skunkworks> mtedad or whatever his name is was wondering about that. (issues with the first card) as he as a few. I thought that was the only one.
[23:47:33] <jmk2> jmk2 is now known as jmkasunich
[23:47:37] <skunkworks> How was the trip?
[23:47:52] <jmkasunich> not bad
[23:48:00] <jmkasunich> got home last night around 7:30
[23:48:17] <jmkasunich> but unloading and other stuff kept me from getting online
[23:48:27] <skunkworks> http://www.electronicsam.com/images/KandT/servostart/ampmess.JPG
[23:49:01] <jmkasunich> does it work?
[23:49:14] <skunkworks> When you get a chance - will you put the rest of the webcam in the video? I will also add that to youtube.
[23:49:34] <jmkasunich> yeah, I'm gonna try to do that tonight
[23:49:50] <jmkasunich> I want to see if I can do a captioned version, with the date and time onscreen
[23:49:51] <skunkworks> jmkasunich: yes - so far. but I have not closed the loop yet. just running pwm out and reading encoders back.. the rolling halscope is pretty cool ;)
[23:52:07] <skunkworks> I had put 3.3k pull ups on the back side of the optos.. I had to change them to 10k as the aprox 3.4 volt from the pluto only ran about 9ma into the optos.. Just not quite enough to switch. only pulled it down to around 6 volts. with 10k it pulled it down to .2v
[23:53:35] <jmkasunich> interesting
[23:53:51] <jmkasunich> I thought most optos would be pretty happy with 9mA
[23:54:59] <skunkworks> I seemed to pick ones that where rated for 15ma operating current. Didn't read too closely I guess.
[23:56:01] <skunkworks> But I think they should be a bit immune to noise. That is my hope anyways. ;)
[23:56:35] <jmkasunich> yep
