#emc | Logs for 2006-07-14

[00:42:18] <Guest798> I have been trying to load Ubuntu Dapper Drake on a fresh Seagate HD and all I et is a disc read error.
[00:48:50] <Guest798> Also, how do I get signed on with a username and pass word?
[01:09:11] <jepler> there will be a short downtime for cvs.linuxcnc.org while the gateway system is down.
[01:20:06] <jepler> and we're back...
[01:20:11] <jepler> did I miss much?
[01:20:25] <cradek> nope
[01:20:37] <cradek> I bet your rain detector will be working soon too
[01:21:48] <jepler> yeah probably
[01:23:20] <cradek> [5345221.163003] hda: dma_intr: status=0x51 { DriveReady SeekComplete Error }
[01:23:20] <cradek> [5345221.163011] hda: dma_intr: error=0x84 { DriveStatusError BadCRC }
[01:23:26] <cradek> looks like I'll be buying a hard drive soon
[01:24:01] <cradek> these new ones are crap - that's only maybe a year old
[01:32:24] <jepler> yuck
[01:33:06] <CIA-8> 03jepler 07HEAD * 10emc2/src/hal/utils/halcmd.c: ignore SIGPIPE. fixes the 'halcmd | false' lockup
[01:33:09] <jepler> well that was easier than I expected
[01:33:13] <Rugludallur> reminds me of deathstars, thank you IBM, that sound will haunt me forever, walking into a machine room and hearing,, wroooooooom, click eeeeeek, wroooooom, click eeeek
[01:35:38] <cradek> cool
[01:35:42] <jepler> there's another problem, and it's thornier. While this is running, halcmd will hold the lock: 'yes show | head -500 | halcmd -kf | sleep 100'
[01:36:02] <jepler> you can't just drop the mutex before doing output, because you need to protect against the linked list changing while you traverse it
[01:36:19] <cradek> doctor, doctor!
[01:36:23] <cradek> ?
[01:36:41] <jepler> at first I thought that's what the OP meant, but luckily it wasn't...
[02:41:17] <jimfleig> Hello, My thanks to Lloyd W. for his help getting me up and running with EMC2 on Ubuntu. I would like to configure the screen display to show 5 axes: X Y Z A B. I was able to do this with by modifying the .ini file in EMC BDI. In Ubuntu I am denied editing priveledges. Why?
[02:54:10] <jimfleig> Hi Bill, I selected your name from the list to see if a message sent to a selected name works. I am new to this.
[03:08:35] <lilo> [Global Notice] Hi all. I should note that the changes that alindeman was making when we ran into problems are designed to make the network more resistant to Tor botnet harassment. Apologies for the inconvenience, and thank you for your patience.
[03:44:08] <lilo> [Global Notice] Hi all. To repeat from the previous message, in setting up some additional safeguards against Tor botnet abuse, we ran into a temporary configuration glitch. It's possible you were still seeing the affects as recently as a couple of minutes ago.
[03:44:43] <lilo> [Global Notice] Things should slowly return to normal. Apologies for the inconvenience, and thank you again for your patience.
[03:48:16] <lilo> [Global Notice] This should be our last glitch, apologies in advance.
[11:01:31] <harty> hi is anybody using mastercam lathe to ganerate toolpaths for emc2 running a lathe
[11:19:58] <fenn> i think lernaean_hydra might be using mastercam
[11:20:20] <fenn> but he doesnt have a lathe set up with emc yet (?)
[11:21:32] <fenn> anyway the lathe spec isn't finished or implemented yet so you wouldnt be able to use canned cycles, constant surface speed, etc
[11:28:57] <harty> just mucking about at the moment but i cant get it to cut a radius
[11:31:11] <harty> mastercam puts the radius in the nc file but emc doesn't take any notice of it think it might be a postproccessor problem
[11:31:59] <cradek> yes LH has a lathe running with emc2, I saw a video of it
[11:32:09] <cradek> I bet he'll be around a little later
[11:33:36] <harty> thanks i will try a bit later on pretty keen to get my lathe cutting stuff other than tapers
[11:37:12] <cradek> the development version of emc2 currently has tool shape compensation g41/g42 and tool XZ tool offsets g43, threading g33
[11:37:42] <cradek> it does not yet have CSS like fenn said
[11:38:20] <cradek> I bet LH can help with mastercam post problems (I can't)
[11:38:26] <cradek> have to run
[11:38:27] <cradek> be back later
[12:06:29] <cradek> what do you mean a radius? do you mean arc g2/g3?
[12:07:04] <alex_joni> hi
[12:07:13] <harty> yep g3
[12:07:28] <cradek> do you have a g18 in the file to switch to XZ plane?
[12:08:20] <harty> no g18
[12:08:31] <cradek> I bet that'll fix your problem
[12:10:05] <harty> does that go at the start of the file or just befor the g3
[12:10:28] <cradek> anywhere before the g3
[12:10:37] <harty> k thanks
[12:10:57] <alex_joni> harty: only once is enough
[12:11:04] <alex_joni> it stays active afaik
[12:11:10] <cradek> yes active plane is modal
[12:11:28] <cradek> bbl
[12:58:20] <alex_joni> bbl
[14:06:39] <CIA-8> 03jepler 07v2_0_branch * 10emc2/src/hal/utils/halcmd.c: backport: fix for the 'halcmd|less' bug
[14:11:04] <cradek> harty: did that fix your program?
[17:20:31] <Jymmm> Hola
[17:23:17] <Jymmm> Hmmmm, the lights are on, but nobody's home.
[17:26:02] <bill203> Zzzzzz
[17:27:08] <Jymmm> bill203: Hey, no sleeping on the job!
[18:04:09] <CIA-8> 03cradek 07v2_0_branch * 10emc2/src/emc/motion/control.c: velocity bugfix for non-trivkins, backported from 1.62
[20:29:09] <Jymmm> Hey les_w !
[20:36:47] <Jymmm> Anyone have any hints/tips/tricks on making making mechanical machines? I want to make my buffer semi automated =)
[20:48:20] <les_w> hey jymmm
[20:48:47] <Jymmm> How goes it?
[20:49:54] <les_w> ah...ok...Had friday fingerburner meeting, and scheduled a meeting with management about building the factory.
[20:50:40] <Jymmm> They don't have facilities to mfg it ?
[20:51:24] <les_w> I will manufacture it. It will be my factory...or at least most of it
[20:51:40] <les_w> depends on how much money they supply
[20:51:46] <les_w> we have to hash that out
[20:51:47] <Jymmm> ah =)
[20:52:50] <les_w> I want them to fund it, so they will prob want part ownership
[20:52:56] <les_w> which is fine.
[20:53:17] <Jymmm> on your land?
[20:53:46] <les_w> no, not here. No skilled labor. But I am looking at towns within 100 miles
[20:54:09] <les_w> Greenville SC is high on the list
[20:54:25] <Jymmm> you would commute?
[20:54:43] <les_w> I would have to have an apartment or something for weekdays I guess
[20:54:56] <les_w> it's 80 miles
[20:55:09] <les_w> good excuse to buy an airplane, huh?
[20:55:12] <Jymmm> or a BIG office with shower
[20:55:18] <les_w> haha
[20:55:58] <Jymmm> conf rm that turns into a music room by night
[20:56:09] <les_w> of course
[20:56:48] <Jymmm> break room that just happens to have a commercial stove with built in grill and hood with capacity for half a side of beef.
[20:56:56] <les_w> anyway we have some negotiations to do
[20:57:14] <les_w> I'll tell you what they usually do....buy you out.
[20:57:27] <les_w> sooner or later
[20:57:41] <les_w> I could handle that too.
[20:57:47] <Jymmm> but they're paying for it, so wouldn't that make it aprtially yours?
[20:57:53] <Jymmm> theirs I mean.
[20:58:02] <les_w> yeah
[20:58:07] <les_w> question is...
[20:58:10] <les_w> how much
[20:58:15] <Jymmm> ah
[20:58:31] <les_w> if it's 51% or more....
[20:58:39] <les_w> I'm just an employee
[20:58:50] <Jymmm> unless of course they are paying you to setup/operate the mfg facility.
[20:58:52] <les_w> with a nice stock plan
[20:59:16] <les_w> well I have asked for $500k for a laser trimmer
[20:59:29] <Jymmm> I'll beta test it for you
[20:59:29] <les_w> which I hope will use real time Linux
[21:00:06] <Jymmm> how big?
[21:00:19] <Jymmm> travel and power
[21:00:25] <les_w> I would only get a little of that money. Most would be for salaries of others
[21:00:46] <Jymmm> no, no, I mean the laser
[21:00:53] <les_w> oh
[21:00:58] <les_w> 50 watts or so
[21:01:05] <Jymmm> WTH?!
[21:01:19] <Jymmm> at least 75 watts
[21:01:23] <les_w> 50 watt yag is plenty
[21:01:30] <les_w> haha
[21:01:33] <Jymmm> oh yag, I though tyou meant CO2
[21:01:39] <les_w> nah
[21:02:02] <Jymmm> I don't know the equiv
[21:02:20] <Jymmm> I know what a 75W co2 is capable of.
[21:02:24] <les_w> know what? I'll bet they will want 51%
[21:02:27] <les_w> betcha
[21:03:02] <Jymmm> Well, does the entire project dead stop if you back out of the deal?
[21:03:21] <les_w> ha
[21:03:25] <les_w> yes I think
[21:03:40] <Jymmm> And have you given them any technical docs as of yet?
[21:03:51] <les_w> sure
[21:04:02] <les_w> but rest assured only I can make the thing
[21:04:25] <Jymmm> well, you KNOW mfg eng is different from R&D so they will need you ther.e
[21:04:42] <Jymmm> you have some fudge room =)
[21:05:00] <les_w> anyway, I'll have no problems there... I am very experienced at setting up hi tech manufacturing
[21:05:02] <Jymmm> just all depends on how much responsability you want.
[21:05:20] <Jymmm> les_w: Sure YOU are, but are they is the question =)
[21:05:46] <les_w> I want to be a guru and walk around and bug people. One of the first things I would do is hire a plant manager
[21:05:51] <Jymmm> are you building the laser? or somethign off the shelf?
[21:06:17] <les_w> not the laser. Most of the money would be for software.
[21:06:26] <Jymmm> ah
[21:06:50] <Jymmm> just learn HPGL =)
[21:06:54] <les_w> heh
[21:07:20] <Jymmm> that's what all the commercial lasers are... glorified plotters that use HPGL
[21:07:28] <les_w> My last integrated manufacturing system did pretty well.....for the heaters
[21:07:30] <Jymmm> as a print driver too
[21:07:43] <Jymmm> brb coffee
[21:07:46] <les_w> k
[21:11:20] <Jymmm> back.... did you see my Q above?
[21:24:11] <stiles> what do you use a 75 watt co2 laster for?
[21:24:52] <Jymmm> wood/plastics
[21:25:58] <bill203> ...blinding small children.
[21:26:20] <stiles> ahh I've only used 2.5kW co2 lasers for cutting steel, thoe we did cut some wood and plastic with them too
[21:26:47] <les_w> sorry was away stiles
[21:27:24] <les_w> I would use a 50 watt YAG to trim mechanical resonators to frequency and Q
[21:28:21] <les_w> I have also used 2 kw co2 for wood carving
[21:29:07] <les_w> I designed a laser carver for a company
[21:29:11] <les_w> many years ago
[21:29:51] <stiles> nice
[21:30:51] <les_w> the trim machine I need now would just vaporize little bits of plastic here and there
[21:31:04] <les_w> on tiny little parts
[21:31:30] <les_w> I have been messing with a 50 watt YAG on a laser marking machine
[21:31:42] <les_w> it's more than enough to do the job
[21:32:09] <Jymmm> les_w: you have one already? whats it's travel?
[21:32:57] <les_w> No, A friend bought a laser marking system to start a small home business on the side.
[21:33:04] <les_w> I helped him set it up
[21:33:06] <Jymmm> ah
[21:33:10] <les_w> it's pretty neat
[21:33:37] <Jymmm> Yeah, I know. I want one SO bad
[21:33:58] <les_w> he paid about $60k for the basic system
[21:34:08] <Jymmm> That's why I dont have one.
[21:34:14] <les_w> heh
[21:34:36] <les_w> it's pretty fast
[21:34:53] <Jymmm> 48x24 with passthru and about 100 watts, I'd be happy.
[21:35:01] <les_w> marks diamonds, hardened steel, all sorts of stuff
[21:35:51] <stiles> does YAG have less HAZ (heat effected zone) than co2?
[21:35:59] <les_w> He's planning to put his wife on running it in the basement, so she won't have to be away at work.
[21:36:49] <les_w> stiles, the wavelength is about 1/10 that of co2, so the beam can be focused into a much smaller spot
[21:37:30] <les_w> the marked parts don't even get warm
[21:37:43] <stiles> thanks for the 411
[21:38:03] <Jymmm> les_w: Do you know the equiv wattage of yag -vs- co2?
[21:38:46] <les_w> well they are just different animals. Many materials are transparent to YAG, but opaque to co2
[21:39:00] <Jymmm> such as?
[21:39:13] <les_w> clear plastic
[21:39:23] <les_w> you can fire a yag right through
[21:39:26] <Jymmm> so yag can't do anything to acrylic?
[21:39:37] <les_w> not much
[21:39:58] <les_w> so you can fire through to vaporize a coating on the other side
[21:40:05] <les_w> which is pretty handy
[21:41:15] <Jymmm> so I couldn't use a yah to cutout shapes in cast acrylic?
[21:41:19] <Jymmm> yag
[21:41:32] <les_w> it would not be very good, no
[21:41:47] <les_w> co2 will blast the hack out of it though
[21:41:51] <Jymmm> wood ?
[21:41:52] <les_w> heck
[21:41:58] <les_w> acrylic
[21:42:15] <les_w> yag will burn wood yes
[21:42:35] <Jymmm> is it becasue acrylic is clear?
[21:43:14] <Jymmm> or could yag cut out shapes in glass?
[21:43:24] <les_w> right. YAG is actually near the visible light range, so if the part appears clear to the eye, it's lkely that the yag will go right through
[21:43:47] <les_w> glass...not sure. I think it would go through.
[21:44:04] <Jymmm> k. I know that c02 can etch glass.
[21:44:12] <Jymmm> but not cut it
[21:44:17] <les_w> right
[21:44:23] <Jymmm> these are all the 100Watt or less range.
[21:44:31] <les_w> yeah
[21:44:37] <Jymmm> It is purrty on marble
[21:45:04] <les_w> yag would cut dark marble best
[21:45:37] <Jymmm> no, I mena etch black marble...it looks awesome!
[21:45:56] <Jymmm> http://www.laserproi.com/en/engr_showcase_detail.php?ID=English_040920185636#2
[21:46:07] <les_w> yes i'll bet it looks good
[21:46:09] <Jymmm> theres a pic of a photo etched in marble
[21:46:11] <les_w> looking
[21:46:44] <Jymmm> too much quartz in granite, but veinless marble looks awesome
[21:47:03] <les_w> nice
[21:47:09] <les_w> must be color filled
[21:47:14] <Jymmm> No, it's not
[21:47:19] <les_w> really
[21:47:23] <Jymmm> I have a sample here
[21:47:32] <Jymmm> It's that way right off the machine
[21:47:39] <Jymmm> less some dust =)
[21:48:01] <les_w> using co2 I see
[21:48:23] <Jymmm> Remember a couple years ago I was looking inot buying one. The owner is 40miles S of me and his garage is full of them.
[21:48:31] <Jymmm> Yeah, GCC are all c02
[21:49:05] <les_w> Well my freind thinks he will make a lot of money with his $60k investment
[21:49:14] <Jymmm> But... I talked to another guy that does urns, and he needs about 75 - 100 wattd.
[21:49:28] <Jymmm> or even 150 watts
[21:49:46] <Jymmm> but it's deep carvings... about 1/8"
[21:50:18] <les_w> well you have to look at setup time...if most of the work is art and stuff bigger lasers might not mean bigger profits
[21:50:32] <les_w> depends
[21:51:02] <Jymmm> No, it's pretty simple stuff.... just that photo engraving into wood with a co2 laser is all raster moves.
[21:51:18] <les_w> just like the carved signs really
[21:51:19] <Jymmm> he can go faster with higher wattage laser is all.
[21:51:31] <les_w> gotta watch how much cam time you do
[21:51:52] <Jymmm> It's all done out of Corel Draw, almost exclusively
[21:51:59] <les_w> Now if it's not custom bigger lasers are better
[21:52:12] <Jymmm> templates. all tempaltes.
[21:52:52] <les_w> like the 100,000 template based "knock on wood" novelty desk items we made
[21:53:05] <les_w> templates are etched brass
[21:53:50] <Jymmm> I looked at GCC, Universal, and Epilog. The epilog dealer for N Cal is a clueless idiot, Universal is nice, just expensive for what you get, and GCC is the china special, but I've heard lots of ppl use them.
[21:54:33] <les_w> Well, my friend is an engineer. He has to put his sales cap on
[21:54:43] <les_w> It's all in selling the stuff
[21:54:48] <Jymmm> That's my problem now as well.
[21:55:31] <les_w> I have had to turn the sign stuff off due to being so busy on fingerburner.
[21:56:06] <les_w> Fingerburners semm to make a lot more money than signs
[21:56:15] <les_w> a whole lot
[21:56:19] <Jymmm> I peddled my wares at the electronics/ham fleamarket last week. EVERYONE said they were cool, nice, ingenious, etc, not one sale. But I was up all night, and didn't have a good presentation either. But I think I need to approach that differently (mail order sorta thing).
[21:56:20] <les_w> heh
[21:57:00] <les_w> yeah often that happens
[21:57:07] <Jymmm> Need to get the thing into a catalog sales
[21:57:17] <les_w> it means something's wrong....
[21:57:25] <stiles> are you selling artistic stuff?
[21:57:40] <les_w> often people like the process, but not the product
[21:57:44] <Jymmm> stiles: edge lit clear acrylic callsigns
[21:57:56] <Jymmm> Nice walnut stand
[21:58:27] <Jymmm> illumination built into the stand itself.
[21:58:41] <Jymmm> brighter than all hell too!
[21:59:04] <les_w> if you are selling at hamfests, how about callsigns with an old fashioned radio "on the air" thing?
[21:59:34] <Jymmm> Eh, just not a fleamarket type item, as 1) they have to be made 2) ppl looking for bargains.
[21:59:53] <Jymmm> les_w: Yep, even ahve a thingy to trigger with 5W of RF too
[22:00:00] <les_w> BTW how much were you asking?
[22:00:33] <Jymmm> les_w: Carved callsign, lighted walnut base, PS, and shipping in the US $40
[22:00:51] <les_w> lead time?
[22:01:00] <Jymmm> nobody asked
[22:01:28] <les_w> I think...people at hamfests are in an instant gratification mindset
[22:01:43] <Jymmm> yeah, and cheap bastards too =)
[22:01:47] <les_w> see it on the table...buy it...you know?
[22:02:00] <les_w> I think that was the problem
[22:02:13] <les_w> yeah expecting bargains....
[22:02:15] <Jymmm> Just the wrong venue
[22:02:18] <les_w> but....
[22:03:02] <les_w> with a pocket full of money in that ideal zombie like suggestable pre purchase trance
[22:04:06] <les_w> if you could just machine em on the spot.....
[22:04:13] <les_w> like I always say
[22:04:20] <les_w> I swear that would work
[22:04:22] <Jymmm> Well, What I was thinking for down the road was to make a small cnc router so I could do them on site. But I need to find a smaller spindle that can do 3/8" shank
[22:04:47] <Jymmm> by small, I mean like 6"x6"
[22:04:50] <Jymmm> travel
[22:04:54] <les_w> trim router. machine an adapter.
[22:05:06] <les_w> yeah 6x6 would be fine
[22:05:27] <les_w> It would work. I know it would.
[22:05:47] <Jymmm> Sure, I just need to build the machine, but a generater, etc
[22:05:57] <les_w> well, yeah
[22:06:17] <Jymmm> and I think about a 5KW generater and they are loud
[22:06:36] <les_w> 5?
[22:06:41] <les_w> why so much?
[22:06:44] <Jymmm> spinle
[22:06:57] <les_w> what is a spinle?
[22:06:59] <les_w> hahaha
[22:07:01] <Jymmm> spindle, steppers, and computer
[22:07:30] <Jymmm> and gawd help me if it aint clena enough
[22:07:30] <les_w> aw couple kw is enough
[22:08:52] <les_w> I have been looking at alternate energy.....
[22:09:06] <les_w> looks like I am going pellet stove after all
[22:09:08] <Jymmm> probably, just thinking I could use it for other things too.
[22:09:38] <les_w> pellets have more than doubled in price over the last year though
[22:09:43] <Jymmm> AZ is the pellet making place =)
[22:10:04] <Jymmm> brb... smoke
[22:10:14] <les_w> well, right now pellets are $250/ton
[22:10:30] <les_w> that's like $1.80/gallon fuel oil.
[22:11:05] <les_w> i'll use the pellet for warm nights and mornings, reg wood for daytime
[22:12:25] <les_w> I was watching cnn, and all this iran/lebanon/gaza crap is going to give us some $4 gas real quick
[22:14:53] <Jymmm> eeeesh
[22:15:16] <Jymmm> gonna have to sell my expidition and but a diesel, then go for the biodiesel
[22:15:29] <les_w> obviously a proxy attack on iran.....
[22:15:36] <Jymmm> Like lil diesel truck
[22:15:40] <les_w> but i'll get off the soapbox now
[22:15:59] <les_w> I'm paying $3.30 for diesel now
[22:16:22] <Jymmm> les_w: any idea on my quesiton about building a automatic polishing machine?
[22:16:43] <les_w> well, they have them for telescope mirrors...
[22:17:03] <Jymmm> I just need to polish the edges of acrylic.
[22:17:10] <les_w> flat or 3d surfaces?
[22:17:14] <Jymmm> 3" circles
[22:17:24] <Jymmm> well from 3" to 6" circles
[22:17:31] <les_w> oh.
[22:17:38] <Jymmm> just the edges.
[22:17:51] <les_w> just like the turkey call sander/poliser....
[22:18:06] <les_w> just a quick release chuck
[22:18:10] <Jymmm> got pics?
[22:18:13] <les_w> and an old servomoter
[22:18:16] <les_w> motor
[22:18:21] <les_w> and a guy
[22:18:29] <les_w> worked fine
[22:18:42] <les_w> you use a vacuum chuck....
[22:18:48] <Jymmm> I was thinking something wher eI could load up a few, then it would cycle thru the pieces.
[22:18:51] <les_w> but otherwise same bit
[22:19:11] <Jymmm> I bought and converted a bench grinder into a polisher.
[22:19:44] <les_w> you could, but my guy could buff out a turkey call finish with auto compound in less than 30 seconds
[22:20:12] <les_w> that's 8 cents labor
[22:20:14] <Jymmm> well, can he do 800 of them?
[22:20:26] <les_w> he did 10,000
[22:20:35] <Jymmm> I meant in a couple hours
[22:20:51] <les_w> well no...but 8 cents is 8 cents
[22:21:02] <Jymmm> well, send him over.
[22:21:04] <Jymmm> =)
[22:21:07] <les_w> haha
[22:22:21] <les_w> your gf like to polish acrylic edges doesn't she?
[22:22:27] <Jymmm> I was going to treat them like coins, let each one drop into place, then have soem friction so they dont spin as fast as the buffing wheel, then periodically apply the compund
[22:22:51] <Jymmm> once 360 deg, drop it down, and have the next one drop into place.
[22:23:04] <les_w> fun to watch but you don't need it to make money
[22:23:08] <les_w> oh btw
[22:23:41] <les_w> I went over to my guy's (the polisher) place yesterday....
[22:23:54] <Jymmm> Ha! power tools scare the shit out of her.
[22:24:03] <les_w> he was sittin on a swing with this girl...
[22:24:12] <les_w> she didn't have a thing on
[22:24:38] <les_w> She said aiee! I better get some clothes
[22:24:48] <les_w> I said:
[22:25:11] <les_w> It's ok. I'm a professional engineer. We are trained for these things.
[22:25:18] <Jymmm> lol
[22:25:23] <Jymmm> how old is she?
[22:25:37] <les_w> he is 78. She is 40.
[22:25:48] <Jymmm> ah
[22:26:09] <Jymmm> lol
[22:26:11] <les_w> I swear I don't know how he does it.
[22:26:28] <Jymmm> he spends to the viarge spams
[22:26:36] <Jymmm> responds
[22:27:02] <les_w> If he was old and rich I could see it...but nobody is going to get rich on what I pay them...
[22:27:57] <les_w> When I said it's ok i'm an engineer, she sat back down in the swing.
[22:28:30] <Jymmm> No need to be modest if nobody minds.
[22:28:46] <les_w> yup.
[22:29:01] <JYmmmEMC> but, how was the view?
[22:29:24] <les_w> rather good
[22:29:41] <JYmmmEMC> then ther ya go
[22:29:42] <les_w> Like I said, I don't know how the hell he does it.
[22:30:02] <JYmmmEMC> undiscovered talents maybe?
[22:30:08] <les_w> I guess.
[22:31:01] <les_w> perhaps he learned something from rubbing turkey calls?
[22:31:03] <les_w> hahaha
[22:31:09] <JYmmmEMC> If you have pics of you turkey call buffing machine, I'd appreciate it
[22:31:21] <les_w> let's see
[22:31:28] <les_w> don't think so
[22:31:53] <JYmmmEMC> I could use all the ideas I can get. I can't polish 800 by hand in a timely manner
[22:32:12] <les_w> it's just a motor, a custom machined quick release chuck, and a variable speed drive mounted on a chunk of mdf
[22:32:44] <JYmmmEMC> think you could takes some pics in the next couple of days and email them to me?
[22:32:52] <les_w> it was just made from surplus junk
[22:32:57] <les_w> i'll try
[22:33:12] <les_w> but you would need a vacuum chuck
[22:33:22] <les_w> not hard to do...
[22:33:52] <Jymmm> I'd REALLY appreciate it,
[22:34:06] <Jymmm> What I have in mind is a bit more elabrite than that.
[22:34:15] <les_w> 3-6" acrylic disks, no holes right?
[22:34:33] <Jymmm> one 1/8" hole for hanging
[22:34:40] <les_w> where?
[22:34:43] <Jymmm> nea rthe edge
[22:34:52] <les_w> ok
[22:35:00] <Jymmm> maybe 1/4" in from the outside edge.
[22:35:01] <les_w> still need vacuum chuck
[22:35:12] <les_w> no big deal
[22:35:23] <Jymmm> got a shopvac worse case
[22:35:32] <les_w> that would be fine
[22:35:47] <les_w> or air venturi
[22:36:09] <Jymmm> no compressor, well no place for a loud compressor.
[22:36:18] <les_w> yeah
[22:37:24] <les_w> machining a vacuum tight rotary fitting is a bit of a chore, but not real real hard
[22:37:40] <les_w> actually iy can leak a little
[22:37:45] <les_w> it
[22:38:35] <les_w> you have 7+ sq inches, so only a little vacuum would hold it fine
[22:38:39] <Jymmm> I'm not quite sure what you mean by "vacuum tight rotary fitting", specifically the "rotary fitting" part
[22:39:23] <les_w> well, you have a round chuck on a motor shaft...like a suction cup
[22:39:29] <Jymmm> k
[22:39:34] <les_w> and you have to get vacuum to it
[22:39:39] <les_w> that's all
[22:39:52] <Jymmm> how do you center the piece?
[22:40:31] <les_w> if by eye is not good enough, a spring loaded set of fingers
[22:40:32] <les_w> 3
[22:41:17] <les_w> some kind of thing that flip or retracts out of the way
[22:41:37] <les_w> perhaps by centriptal accel
[22:41:59] <Jymmm> Well, these pieces are flat, then just need to spin MUCH slower then the grinder.
[22:42:02] <les_w> oops
[22:42:48] <les_w> yea fingers gome out...hold the edge, retract out of the way when it starts spinning
[22:42:53] <les_w> come
[22:42:54] <Jymmm> I was thinking of some wheels spaced to accept whatever diameter the piece is for alignment purposes.
[22:42:56] <les_w> gome?
[22:43:07] <Jymmm> gnome elfs, pixies
[22:43:20] <les_w> heh
[22:43:33] <les_w> anyway, a bunch of ways to do it
[22:43:47] <les_w> machining is involved of course
[22:44:55] <Jymmm> you gave me an idea.... two discs that would clamp the workpiece from both side, one being spring loaded.
[22:45:15] <Jymmm> two idler wheel below to center the workpieces into the clamps
[22:45:17] <les_w> yeah, that would work
[22:45:20] <les_w> no vacuum
[22:45:41] <Jymmm> then put friction on the clap rods to reduce the speed of the spinning discs
[22:45:52] <Jymmm> clamp
[22:45:59] <les_w> whaty is a clap rod?
[22:46:28] <Jymmm> les that's what happenes when you are NOT a professional engineer and see you friends cute old ladty nakkid
[22:47:05] <les_w> I figured it was some kind of applause sticks or some anatomical part
[22:47:24] <les_w> hahaha
[22:47:38] <Jymmm> clap == STD (also type for clmap) amd rod == between your legs =)
[22:47:46] <Jymmm> typo
[22:47:47] <les_w> oh.
[22:47:50] <les_w> hahaha
[22:48:18] <Jymmm> clap == STD (also typo for clamp). and rod == between your legs =)
[22:48:21] <Jymmm> there we go
[22:48:36] <Jymmm> I think I have one of your beta kybd's les =)
[22:49:10] <Jymmm> I've already burned out the LED's on this kybd. But what do you expect for a 12yo one.
[22:49:30] <les_w> yeah these keyboards suck...and btw are NOT selling
[22:49:38] <Jymmm> lol
[22:49:41] <les_w> and my friend is about to go bust
[22:49:58] <les_w> he pot a couple hundred k into the project
[22:50:08] <Jymmm> ouch
[22:50:24] <les_w> it was another one of those "neat idea" but no sales things
[22:50:25] <Jymmm> what is so special about it?
[22:50:36] <les_w> hang on
[22:51:20] <les_w> http://www.keyboardorganizer.com/
[22:51:34] <les_w> sales have been disapointing so far
[22:52:50] <les_w> well he is changing the looks...perhaps that will help
[22:53:48] <les_w> and of coure I advised him to fix the crappy sticking keys
[22:54:03] <les_w> but that is not why they don't sell of course
[22:54:30] <Jymmm> You know, *I* would have just made a thing that fits under any kybd, instead of just intergrating the two.
[22:54:45] <les_w> I think MSRP ought to be lower
[22:55:11] <Jymmm> well the wireless usb is only $50
[22:55:31] <les_w> it is neat, and I use the storage, but I wouldn't pay extra for it
[22:55:41] <les_w> I have the first prototypes
[22:55:46] <les_w> a crate of em
[22:56:00] <Jymmm> he needs to get it into a vendor
[22:56:14] <les_w> he needs wallyworld.
[22:56:23] <Jymmm> dont we all
[22:57:26] <les_w> well he did drop prices a little
[22:57:38] <les_w> actually hr is on my skype right now
[23:01:01] <les_w> We worked together a lot over the years...we did the starfighter analog joystick and electronic trivial pursuit game years ago
[23:01:07] <les_w> those both sold well
[23:01:48] <les_w> patent is expired on the starfighter.
[23:04:00] <Jymmm> sounds like he has the facilitie, maybe he should get back into the joystick business
[23:04:06] <Jymmm> facilities
[23:06:51] <les_w> brb phone
[23:06:55] <Jymmm> k
[23:15:58] <Jymmm> * Jymmm looks for cheeta!
[23:37:18] <les_w> long call.
[23:37:27] <les_w> 99 yo grandma
[23:38:31] <les_w> I have to mix up another batch of bordeaux fungicide for our tomatoes
[23:38:39] <les_w> organic approved
[23:45:17] <asdfq-shop> jepler: BDI 4.49 is currently drawn from Debian/stable - in which there *is* python2.4 - but it's not the default, *and* it doesn't have the subprocess module
[23:46:48] <alex_joni> asdfq-shop: what's the subprocess module?
[23:48:17] <asdfq-shop> Something jepler decided to use to confound compatibility :P
[23:49:16] <asdfq-shop> python2.4 has the new subprocess module, which replaces certain aspects of the sys or os modules
[23:53:36] <asdfq-shop> apt-get'ing python2.4 and associated stuff from testing - 19 MB - not so bad
[23:56:04] <lilo> [Global Notice] Hi all. Reminder: various netlink and other browsers have an exploit which allows someone to type a 'DC C' string (without the space) on channel and drop people off the network. We've had ongoing problems with hit and run artists knocking people off the network using that exploit.
[23:56:31] <lilo> [Global Notice] You may want to reconnect to the network via port 8001, rather than port 6667 (the default). This will render the exploit ineffective. Thanks.
[23:59:22] <lilo> [Global Notice] whoops, excuse me..... that should be 'routers' rather than browsers'....typo of the day. Thanks. :)
