00:00:10 sup 00:30:35 how are you doing robin_sz ? 00:31:03 It doesnt seem as if anyone is on 00:37:32 hey gezr 00:39:11 robin_sz : anything new? 00:39:45 I ordered me a gasket kit and a climber manual 00:40:00 and just finished leak testing all the valves, things look good 00:40:08 kewl 00:40:15 my car exploded 00:40:19 no way? 00:43:52 way 00:43:55 well the negine 00:43:57 engine 00:44:04 timing belt lost teeth ... 00:44:14 diesels are all interference engines 00:44:19 death. 00:44:35 valve meets piston? 00:45:00 well, that sucks, hope it doesnt run you too much 00:46:44 SteveStallings has joined #emc 00:46:56 picnet has quit 00:52:35 nah, the car is dead, it was a cheapy 01:19:01 stevestallings2 has joined #emc 01:19:39 stevestallings2 has quit 01:37:20 SteveStallings has quit 01:54:38 picnet has joined #emc 02:49:16 jmkasunich has joined #emc 03:06:33 picnet has quit 03:19:14 good evening, jmk... 03:21:09 danfalck has joined #emc 03:21:43 hi 03:21:57 How are thing on your coast this evening? 03:22:06 cold, as usual 03:22:22 have you heard about the EMC codefest plans? 03:22:36 hehe... I'm so glad not to live in a cold place anymore. 03:22:41 Nope, I'm unaware of codefest plans. 03:22:50 (BTW, I'm not on the coast, I'm in Cleveland OH) 03:22:57 Is NAMES coming up? That's when they did it before. 03:23:15 Oh... Ohio... That's not 'east coast' at all :) Just the timezone, eh? 03:23:20 NAMES is April 23/24 (Sat/Sun) 03:23:30 yep ;-) 03:23:39 I'm originally from Chicago. I'm glad to have escaped snow... 03:23:57 the codefest will be the week after NAMES, starting Monday 4/25 and running till Thursday 4/28 03:24:10 we're having it at NIST, just outside Washington DC 03:24:30 nifty. Who's likely to attend? 03:24:39 you I hope ;-) 03:25:09 me, paul, ray, matt shaver, cradek (I think), jepler (I think), steve stallings 03:25:34 attendence is gonna be limited to folks with serious interest in coding on EMC, perhaps 12 people total 03:25:41 Welp, I just emailed myself a note to add it to my calendar when I get home and see what can be done... 03:25:57 last year we had some total newbies, folks who simply wanted to get a BDI install, etc... 03:26:13 helping those folks is important too, but you can't get much coding done while doing that 03:26:22 right. 03:26:40 Hopefully we can continue to make that process easier so ordinary folks need less help, though... :) 03:26:54 Fred Proctor from NIST will be our host, but I don't know if he'll be involved constantly, or if he'll drop in as his job permits 03:27:25 hmm. cool. 03:28:03 Do you know roughly how many people are on the emc-users and emc-dev list? (I wonder stuff like how many people are trying emc, how many are using it, how many have interest in develping for it, etc in these cnotexts...) 03:28:06 yep... there will be another event at Roland Friestad's place (Cardinal Engineering in Illinois somewhere) in June - a NAMES alternative focused on CNC... we're planning to have a more user/integrator oriented thing there 03:28:21 lemme check 03:29:10 users: 403 03:29:31 dev: 161 03:29:43 Wow... That's a BUNCH of folks on the dev list! 03:29:45 most are lurkers 03:30:09 they read the dev list to keep abreast of what is happening, not because they're developing 03:30:31 Hmm... seems like an opportunity there to get involvement if we organized it right. But that's a big challenge. If even 1 out of 10 on the list contributed regularly.... wow... 03:31:11 there are 43 developers on SF, again many are inactive. In some cases, people asked to be added as developers just because it lets them avoid the 4-24 hour delay between developer CVS and anonymous CVS 03:31:35 right. 03:32:22 there are 20 subscribed to the commit list... some of those are also just interested in knowing whats going on, but that is probably the closest we have to a list of active developers 03:33:02 I think I'm on there twice :) 03:33:36 emc@starks.org and zwisk@users.sourceforge.net 03:33:49 (I'm list admin, I get to look at the membership ;-) 03:34:30 yup... you got it. It didn't like that i was submitted updates without being on the list, so I had to add the souceforge one... 03:34:51 (I know you're list admin... Which is why I asked you about numbers :) ) 03:34:59 you need to be on there with your SF addy to avoid your commit messages from being bounced 03:35:17 the other addy is for receiving only 03:35:40 hmmm.... that's a way to identify the lurkers 03:36:01 anything other than blah@users.sourceforge.net is a listen only address 03:36:11 lurkers arent' @sourceforge.net, I guess.. 03:36:20 blah@users.sourceforge.net _can_ commit (doesn't mean they do) 03:36:28 right. How many are lurkers vs. submitters? 03:36:34 8 from SF 03:36:44 wow... whittles the numbers down, doesn't it... 03:37:24 alex joni, cradek, ebo (he's gone for all practical purposes), jon elson, me, paul, ray, and some dude named zwisk 03:37:47 yeah, I'm bummed we lost ebo... 03:38:10 robin_sz has quit 03:38:19 I think he could have been a good resource if we didn't have an impedence mismatch of personalities as a group with him. 03:38:38 I like that - impedance mismatch ;-) 03:38:45 (and I agree) 03:39:16 yeah... I just need to work on my spelling :) 03:39:43 I didn't even notice the spelling' 03:41:05 So, I've been doing some further conceptual refactoring of hal... I'm thinking maybe I'll try to use dia sometime and make some diagrams.... 03:41:47 I've been distracted lately... busy week here 03:41:58 just blew up a prototype 1000HP drive at work 03:42:09 yeah... same here. It's hard to find time for 'fun' stuff. 03:42:13 and messing with other things at home 03:42:23 ooh... 1000HP? What does that run? 03:42:30 big motors ;-) 03:42:44 mm... yeah. :) 03:42:49 paper mills, big pumps, all kind of stuff 03:43:08 wow. So you're a hard-core EE by day, eh? 03:43:16 yep... power electronics 03:43:34 nifty. I should ask you about my desires to build a VFD sometime. 03:43:52 that's what I do - VFDs. 03:44:13 wow... how perfect. What would you recommend for a series 1 bridgeport? 03:44:37 I haven't worked on one rated less than 200HP in years :-( 03:44:48 Haha... hmm.. ok. I need a bigger mill :) 03:45:02 What do you run EMC on? 03:45:38 I work for Rockwell Automation (Allen Bradley/Reliance Electric), but our small HP drives are kinda pricey, I think the concensus for 1-5HP is Hitachi or some other Eastern models 03:45:57 right now I don't have EMC on any machine 03:46:07 I have a Shoptask 3-in-1 that I want to convert to CNC 03:46:38 just finished converting the Z axis (quill) from rack/pinion with 0.050 backlash, to ballscrew 03:47:00 but like most projects, the conversion is going slowly 03:47:17 yeah... I picked up a Hitachi .. 150? Not sure on the number. I just wish I could interface the VFD easily to the computer. It has a wanky proprietary profibus interface. 03:48:11 Most fun projects do take a lot of time, and seem to go slowly because we're impatiently trying to get to the part where we use what we're making! :) 03:48:28 most drives have wanky proprietary interfaces, but they usually also have inputs for run/stop and 0-10V speed reference 03:48:50 I hate proprietary stuff 03:49:14 yes, that's true. But it'd be easy to plug a serial port into the thing and write emc software to talk to it. it's harder to break everything out to analog current loops and a bazillion inputs that need to be opto-isolated. 03:49:23 I trashpicked a big pile of AllenBradley 1394 AC servo stuff from work, but the proprietary interfaces make it almost useless 03:49:29 (Easy, I maen, if it weren't proprietary.) 03:50:04 But you work there... surely you can get a compatible driver to talk to it, right? 03:50:16 nope - it's a big company 03:50:25 doh. Bummer. 03:50:44 the system is modular - I think I can reverse engineer and use the axis modules (power sections) and replace the control part 03:51:02 or maybe I'll just sell 'em on eBay ;-) 03:51:13 so many projects, so little time 03:51:44 this evening I was troubleshooting a Tek instrument that was being scrapped 03:52:02 like a big digital storage oscilloscope? 03:52:28 nope - tho I've got a DSO here 03:52:38 A TVC-501 time to voltage converter 03:53:08 it's really nice for measuring jitter, or PWM signals, or step pulse trains 03:53:18 (assuming I can repair it) 03:54:00 It's amazing what a big company scraps 03:54:03 nice. 03:54:20 I just unloaded a beautiful 60" tall 19" rack cabinet 03:54:28 Yes, it is. But, in reality, it may not be worth the big company's time. (It's totally worth free time for us individuals, though!) 03:54:38 from a DEC Alpha server 03:54:53 I didn't want the server - too strange - but the rack is really nice 03:54:57 Yeah, I picked up 4 rack cabinets like what you're describing. Make great shelves in the garage, and are on BIG wheels to roll stuff around. 03:55:27 this one even has two full extension ball bearing shelves, so you can pull a system completely outside the cabinet to work on it 03:55:55 I've gotta re-arrange the piles in the basement so I can bring the rack inside 03:56:07 yes, those are nice. We threw away a bunch of those roller bearing glides at a company I worked at back in '99. Wish I would have saved those! 03:56:08 then maybe I'll finally have some bench space 03:56:22 ooh... a basement. That's something I wish I had out here. 03:56:44 the problem with basements is getting the heavy stuff and and out 03:56:51 mine's too small anyway 03:56:57 (better than none I guess) 03:57:05 where do you have your machine(s)? 03:57:06 yes. I want a basement on a hill with a garage door on the hillside. 03:57:26 My tools are all in the garage. a 2 car garage that sometimes has a car in it is just not nearly big enough for all the toys. 03:57:44 I have a Van Norman #12 mill and a SouthBend 13" lathe in the garage - too heavy to get inside 03:57:52 It's hard to beat a basement for large raw concrete space! 03:58:08 but that means I rarely use them in the winter, and fight a constant battle against rust 03:58:23 I have a Logan 12" and a Jet ... couldn't even tell you what... next to my bridgeport in the garage. Not enough space to get around them all. 03:58:52 my mill: http://home.att.net/~JEKasunich/vannorman/VN_Home.htm 03:59:00 I also have an ancient #3 grinder. I don't even know how to use it. I just couldn't hardly see it go to scrap, so I saved it... but... now I really would love the space back! 03:59:43 my bench: http://home.att.net/~JMKasunich/Pics/bench.jpg 03:59:45 ooh... horizontal and vertical... 03:59:55 I hope to move the stack of computers on the right into the rack 04:00:14 And rack mounted cases... 04:00:27 very nice... 04:00:33 all from the dumpster 04:00:40 incredibly nice! 04:00:46 the top one is the compile farm - 8 individual PCs in one box 04:00:51 It is amazing what you can find dumpster diving. 04:00:52 (only 200MHz tho) 04:01:05 the middle one is 600MHz P3 04:01:23 I have another one similar to that, 500MHz P3, still setting on the floor 04:01:34 whoa... nice. I that some sort of early blade system? (with 8 pc's?) 04:01:40 yes 04:02:00 ISA backplane, 16 slots, split into 8 two slot chunks 04:02:12 hmm... interesting. 04:02:15 one blade goes in the left slot of the pair 04:02:22 any ISA card in the right slot 04:02:34 each blade has video, SCSI, IDE, and ethernet 04:02:40 sweet. 04:02:54 the rack contains a built in 8 way KVM switch which also muxes the 3.5" floppy 04:02:56 So you have 8 drives stuffed in there too? 04:03:06 and there is space for 8 hard disks 04:03:09 (And scsi drives at that?) 04:03:20 some are scsi, some are IDE 04:03:23 oh... you said ide too.. yah.. 04:03:30 the original drives were 2G scsi 04:03:50 a build farm sounds like a perfect use for 'em... 04:04:04 yep... not much else that makes sense 04:04:47 I can't wait to get that stack off the bench 04:05:04 (at one time it was worse - I had a laserjet II on top! 04:05:21 just barely fit under the flue pipe from the waterheader 04:05:31 heater 04:05:32 I've got a room full of that sort of stuff. I have a pile of old laptops that I need to do something with at the moment... 04:05:49 I'm a terrible techno-packrat 04:06:05 me too. Who knows when that stuff could come in handy for some sort of project?! 04:06:28 picnet has joined #emc 04:07:33 greetings picnet... 04:07:56 Hate to say hello and goodbye right away, but I think I'm gonna find smoe dinner.. 04:08:16 the problem is that in order to have the thing you need when you need it, you gotta have an enormous pile of stuff, and at least some kind of system so you can find things 04:08:34 so true. 04:08:40 for every one you use, there are 10 or 100 that you don't... but if you don't have that many, you won't have the one you need 04:09:02 The other thing is that finding things in the junk, you don't get to choose what or when things show up... You have to have a stockpile to queue interesting things up into... 04:09:10 right 04:09:21 like that rack... I've been wanting one for a couple years 04:09:45 last week the server appeared in the loading dock with a "scrap" sign on it, so I swooped down and nabbed it 04:10:03 Exactly. I did the same thing with the racks I got. Gotta jump when they're available. 04:10:25 same with the 1394 servo stuff... I have no idea when or if I'll use it, but it was too good to pass up 04:10:47 sounds interesting. firewire based servos? 04:11:11 nope 04:11:17 wait one 04:11:58 my employers are assholes! 04:12:24 the allenbradley website seems to be inaccessible from my linux box... works great from winblows 04:12:32 blech. 04:12:46 I was gonna send you a URL for the system, with a couple pics and such 04:13:11 hmm. oh well. I have no winblows box anyhoo. :) 04:13:50 I gotta takeoff and do the dinner thing. I may stop back a bit later and see who's about. g'night jmkasunich, and all... 04:14:04 goodnight - I'll be asleep when you get back 04:15:10 a little ohming out of this instrument, then bed for me 04:15:12 night all 04:15:14 jmkasunich has quit 04:56:30 febisfebi has quit 05:13:57 picnet has quit 06:07:05 picnet has joined #emc 07:26:20 jf353 has joined #emc 07:44:03 picnet has quit 08:07:41 picnet has joined #emc 08:29:09 alex_joni has joined #emc 08:37:41 picnet has quit 08:46:28 alex_joni has quit 09:09:27 CIA-temp688 has joined #emc 09:10:04 CIA-temp688 is now known as CIA-12 09:10:05 CIA-7 has quit 09:35:15 robin_sz has joined #emc 09:39:26 robin_sz has quit 09:57:32 acemi has joined #emc 10:08:16 picnet has joined #emc 10:25:28 ChanServ has quit 10:25:28 pemmet has quit 10:25:28 jf353 has quit 10:25:28 danfalck has quit 10:25:28 ccjoe has quit 10:25:28 cradek has quit 10:25:28 les has quit 10:25:28 A-L-P-H-A has quit 10:26:09 ChanServ has joined #emc 10:26:09 jf353 has joined #emc 10:26:09 danfalck has joined #emc 10:26:09 cradek has joined #emc 10:26:09 pemmet has joined #emc 10:26:09 A-L-P-H-A has joined #emc 10:26:09 les has joined #emc 10:26:09 ccjoe has joined #emc 10:41:41 picnet has quit 11:33:51 LOL 11:34:04 I asked for a example on how to use c++ togther with the plc's I am working with 11:34:23 I got a 17mb example... of a realtime kernel.. 11:43:15 robin_sz has joined #emc 11:59:06 alex_joni has joined #emc 11:59:06 alex_joni is now known as alex_joni_ 11:59:06 alex_joni_ has quit 11:59:34 alex_joni has joined #emc 12:08:51 picnet has joined #emc 12:15:20 greetings all... 12:21:26 robin_sz has quit 13:25:41 robin_sz has joined #emc 13:26:09 vasquez has joined #emc 13:26:40 hello alex 13:29:39 SteveStallings has joined #emc 13:29:53 hey anon 13:29:54 hello steve 13:30:07 oohh.. robin is also around ;) 13:30:20 hi alex, any sight of paul lately?

13:32:18 it's code-hell 13:32:27 yeah probably I havent had time to look at it too much 13:32:36 is it proprietary? 13:32:47 probably 13:32:57 well.. ;) 13:33:11 I would have asked you to mail me a copy... but in that case .. better not 13:33:13 :P 13:33:16 it's of no real use.. though 13:33:27 I am just curious on how to use c++ togther with the plc's.. 13:33:41 the priority stuff is somthing I can make up for myself if I need it :) 13:33:45 what interface do you have? 13:34:03 interface? 13:34:09 for conecting to the plc? 13:34:13 yup... 13:34:17 canopen/rs232/usb/ethernet/flash memory 13:34:17 serial? 13:34:25 although just can and rs232 on this one 13:34:27 uuuhhhhh 13:34:28 :D 13:34:39 rs232 would be the easiest way 13:34:41 they'll talk with pretty much anything :) 13:34:48 but you need a command set 13:34:52 and description 13:34:55 how to talk to it 13:34:58 already written that :) 13:35:07 then what's missing? 13:35:28 * alex_joni prods robin_sz 13:35:30 oh, I was curious since I am thinking about implementing my filters in c++ since it'd be more efficient.. 13:35:46 you mean the stuff you program into the PLC? 13:35:56 that is what you want to code in c++ ? 13:35:59 parts of it.. 13:36:01 meep? 13:36:02 yeah 13:36:12 * alex_joni needs your experience ;) 13:36:18 adaptive filters to ignore pressure spikes from real stuff.. 13:36:19 you do? 13:36:23 what do you think of : http://www.rollon.com/english/products/uniline.htm 13:36:52 with real stuff I mean legetimate pressure and not just pulses from the huydralic system.. 13:36:56 :) 13:37:03 I see... 13:37:33 robin_z has joined #emc 13:38:36 alex_joni: its a linear slide :) 13:38:41 lol 13:38:42 I know that... 13:38:50 right .. 13:38:52 so .. 13:39:00 it has a belt drive inside 13:39:08 you can connect the motor to either end 13:39:11 thats fine 13:39:15 now ... 13:39:16 :) 13:39:27 I plan to use a G340 + DCmotor + encoder (on the other end) 13:39:46 how do you plan to set the torch height? 13:39:51 on the X axis (2 slides with a connection between them) 13:39:57 nope 13:40:17 at first no, maybe later with an z-axis (only for height controll from plasma-voltage) 13:40:24 not actually connected to the controller 13:40:30 right ... well .. you have 2 choices 13:40:37 1) some sort of Z axis 13:40:49 2) some sort of plate rider (rolling ball bearing) 13:41:20 vasquez has quit 13:41:25 or some sort of manual adjustment ... 13:41:33 to set the height for the complete sheet... 13:41:35 I suspect it is not stable enough for 2 .. the twist and torsion will make it innacurate as the balls bounce around the shhet 13:41:44 alex_joni: that wont work 13:41:48 alex_joni: guaranteed 13:41:51 :) 13:41:53 really?

19:30:28 foam. 19:30:35 turbocnc wouldnt go any faster.. 19:30:40 afaik there's no motion planner.. 19:30:45 so it dosent interpolate motion 19:30:48 ugh 19:30:52 it stops the axis:es each direction change.. 19:31:07 so it's slow as fck.. 19:31:11 why do you use it? 19:31:13 even when running at 1000mm/min 19:31:23 because emc and I had a fight last week.. 19:31:33 haha 19:31:38 sounds like you lost 19:31:46 cradek: Yeah hard.. 19:32:03 are you going to kiss and make up soon?

19:33:50 no 19:33:57 I NEED EMC! 19:34:00 the old planner blends lines 19:34:03 *grins* 19:34:07 the new planner blends lines and arcs both 19:34:24 you could try both 19:34:38 yep.. 19:34:49 * anonimasu longs for a program with good lookahead 19:35:03 you want emc/segmentqueue then 19:35:09 yeah :) 19:35:15 I'll install it again tomorrow.. 19:35:17 it works *great* 19:35:23 I cant live with this crap anymore.. 19:35:42 the part is a 3d surface.. 19:35:49 but so ther's lots of direction changes.. 19:35:50 :) 19:35:54 want to see it?

19:38:10 like in what program did you design the knob? What did you use to make the gcode? 19:38:17 visualmill + solidworks 19:38:37 I currently do this... myself... draw the program in autocad, and manually do the gcode... but I am only doing it for 2d (lathe) work. 19:39:10 picnet has quit 19:39:13 :) 19:39:27 I coded some g-code but when you can use a cam program it's hillarious :) 19:39:45 why's that? I've tinkered with mastercam. 19:39:49 the part took maybe 20 minutes to cad and less to generate the toolpaths.. 19:40:04 yeah, cause it's automated. 19:40:09 yeah :) 19:40:21 isnt that one of the points of having a cnc ? 19:40:25 ^_^ 19:40:30 yes. 19:41:08 I went back to that local store, to settle my account. :) I didn't want to wait longer to pay it off... they forgot about my account already... and it was less than 24hrs. :) 19:41:19 hehe 19:41:19 ok 19:41:21 that's nice 19:41:23 it was only $10... but it's the principal. :) 19:41:27 agreed 19:41:59 they don't take advantage over me... and I don't want to over them.

They have a local manufacturing plant. 20:03:05 they are super precise :9 20:03:15 BB-105C2 Ceramic 5x10mm Bearing 20:03:16 19.00 20:03:19 yeah, but I spent #30 on two bearings. 20:03:22 $40 20:03:23 $30 20:03:26 finally. 20:03:28 I can type, really. 20:03:34 yep.. 20:03:54 I need speeds over 30000rpm 20:04:18 :) 20:04:21 I actually need two or three bearings to make a spindle... that go around that speed. 30K+ RPM 20:04:33 more like 120000at max 20:04:53 the spindle I want is only rated for 30K. and costs $180USD. :( 20:05:04 :) 20:05:10 that's cheap :9 20:05:17 spindle was mean to be chuck. 20:05:21 ah ok 20:05:23 I'm mkaing the spindle. 20:05:24 still cheap :) 20:05:50 each of my servos was around 600~ 20:05:57 small galil ones.. 20:06:04 http://www.mcmaster.com/itm/find.asp?searchstring=2823A32&sesnextrep=501333187300961&tab=find&FastTrack=false tell me if that link works. 20:06:19 if not it's part number: 2823A32 on www.mcmaster.com 20:06:49 it dosent 20:07:19 drill chuck? 20:07:43 you really should get a real mill chuck.. 20:07:46 :) 20:08:44 the endmills I'm using are 3mm dia. 20:08:53 endmill shafts that is. 20:09:19 tiny stuff :) 20:09:24 I can see why you need that kind of speed 20:09:35 yes. I have another spindle that does 5K already. 20:09:49 that uses W20 collets. 20:10:10 W20, swiss made Schuablin standard. 20:10:52 nice stuff, expensive though. and doesn't go at the rpm I require. :( 20:11:06 :) 20:11:51 I dont know if I could use rollerskate bearings.. 20:12:03 Abec 5 and 7 yeah I could. 20:12:19 abec7 20:12:20 :) 20:12:39 http://www.rceracing.com/lowfriccerbe.html 20:14:03 the stuff I'm looking at is abec 9... and I'm guessing the price is going to be costly... but probably less than < $100. 20:14:13 this spindle hasn't even been started yet... as I don't have the bearings. 20:14:19 I need the bearings first. 20:14:36 so I can maching the spindle, and housing... no point in doing any of it before I get the parts I require. 20:15:05 I think the abec7 bearings that goes to 41000rpm will handle double that without problems.. 20:15:57 but well I might talk to skf about bearings.. 20:16:02 but it'll cost a arm 20:16:04 ^_^ 20:16:21 haha... abec 7 are less than $8USD each. 20:16:23 on mcmaster.com :) 20:16:44 m 20:16:45 nm 20:16:49 I was looking at abec 5 20:16:51 not 7 20:17:09 ah ok 20:17:58 I hate the prices on stuff.. 20:18:01 everything's expensive 20:18:26 I could actually have a oil bearing.. 20:18:36 but well, machining the pices isnt somthing I could do.. 20:18:54 the ra that's needed are way what I can produce 20:20:41 jf353 has quit 20:21:27 I would need a new lathe and a toolpost grinder 8 diamond wheel.. 20:21:35 and all that stuff costs more then buying good bearings :9 20:22:14 hehe. :) 20:33:43 picnet has joined #emc 21:10:11 whats up ya'll 21:10:11 machining. :) 21:10:11 :D 21:10:11 Made 6 identical lengthed spacers 21:10:11 and that took me like 40 minutes. :( 21:10:11 I'm so slow. 21:10:11 I only need 4... but this is just incase the tap breaks within the part. [always scared of that. 21:10:11 talking bearings hu? 21:10:11 ] 21:10:11 was... 21:10:11 I have a few bearoig books around here 21:10:11 Abec 5 all cost aroun $10USD. Abec 7... cost around $120USD 21:10:11 Same... I've got Forenten or something... SKF, and NTN [cd-rom] 21:10:11 hm, does skf list prices`? 21:10:11 I dont think they do 21:10:11 how fast you gonna whirl them about? 21:10:11 no. no prices. 21:10:11 my application. max I think I'm gonna be going is 15K. 21:10:11 me? ^_^ 21:10:11 unless I'm grinding, which I will than be going at atleast 30K. 21:10:11 ill be right back 21:10:11 30K rpm. 21:10:11 'ight. 21:10:11 120000 max.. 21:10:11 :D 21:10:11 somwhere around there.. 21:10:11 abec 5 will be good enough for my application. :) 21:10:18 why not just buy a turbo? 21:10:22 just wondering... 21:10:51 a-l-p-h-a: a supercharger costs 4000$ 21:11:36 and I have a turbo housing and a good impeller.. 21:11:52 A-L-P-H-A : check or watch ebay for air grinding spindles 21:11:58 a-l-p-h-a: the same reason your not buying a spindle.. 21:12:04 :) 21:12:07 probably 21:12:16 anonimasu, COST... and application. 21:12:27 that way you can save lots on your main MILLING spindle 21:12:29 The spindles I see, are +$5K. 21:12:34 :) 21:13:08 thats cause they are using 3k worth of bearings in 6 bearings 21:13:48 really? dang. 21:14:55 they are not just using a abec 7 bearing thats off the shelf 21:15:35 well... I don't need continuous duty though either... and I don't mind replacing the bearings, say after 15 hours of use. 15 hours of use could probably give me ALOT of parts. 21:15:38 all matched sets, they even come with a special grease its all wierd 21:15:54 I see two air spindle bearings... 21:16:09 I don't think I need air... which means I gotta run lines from my garage to my basement workshop, which I don't want to do. 21:16:59 well an air grinding spindle for use if you plan on using grinding wheels 21:17:26 yeah... I could deal with that. I do also have a cheap cheap dremel clone. 21:18:04 but my application is just do this: use a 1/3 or a 1/4HP motor, spinning at 1750, make a pully and use some polyrope. 21:22:15 Hmm... wow. I would need a 6" pully @ 2000rpm to drive a 1" pully at 12000rpm. Lets see if I make an addition pullyset what would happen. 21:22:54 hehe 21:23:05 Well. if I use 3 pulleys. 21:23:12 picnet has quit 21:23:15 I wonder how much speed regular bearings will take.. 21:23:34 3" => 1" connected to 3" => 1" it would do the job as well. 21:24:29 abec 5? 48K rpm. 21:24:35 for an 8mm bore 21:24:39 hm abec7 ? 21:24:54 abec 7, 12mm bore, 60rpm. 21:25:00 60k rpm 21:25:12 hm, I'd still need better bearings :/ 21:25:20 if you get bigger, the speed drops conderably. Page 1021 on www.mcmaster.com 21:25:47 smaller would be even better :9 21:26:20 well... the Abec5 bearing I see, that's 0.0469" Bore... is rated for 120,000rpm. 21:26:24 but it's life would be short I would think. 21:26:35 I need even better bearings.. 21:27:07 :) 21:27:19 * anonimasu starts sawing an arm off 21:27:31 don't for a kidney as well. 21:27:48 :) 21:27:49 haha 21:27:58 More machining. :) hehe. dang. it never stops. :) hehe 21:31:51 nice 21:33:08 I cant imagine what im gonna do for a spindle 21:33:47 as far as bearings go, its gonna cost plenty im sure of that much 21:34:15 thats what I get for wanting to copy a full size machine into miniture 21:34:34 gezr? if you don't need to drill with it... it's easy. :) And also ifyou want a drawbar or not. 21:34:40 what kinda collet system do you want to use? 21:35:38 im going to intergrate a special tool system into the main spindle 21:36:05 that way I dont have to worry about grinding say an r8 taper or anything fancy 21:36:27 and I will be drilling, milling, all sorts of stuff 21:36:39 2 set of 3 angular contact bearing sets 21:36:45 im hopping for 8k max rpm 21:37:24 I tend to be brutal with machining, so I need power 21:37:51 I'd like a 5hp motor on my mill. :) 21:37:56 I'm happy with 1hp on my lathe. 21:37:59 does what I need it to do. 21:38:14 oh, I started to be a little more agressive on my lathe. 21:38:17 I dont need more then a horse or 2 21:38:21 good :) 21:38:27 I'm making chips, not ribbins. :) 21:38:36 A-L-P-H-A : if you have machining questions I can help you with that stuff 21:38:39 well... sometimes I get chips, sometimes I get 2" ribbins 21:38:49 thanks. :) 21:39:08 I had in order to break the chip on a part earlier this week jack the feed rate up to .028"/rev 21:39:33 now the chip was still about 8 inches long but 1/2" curl and was breeaking 21:39:51 this is at work and not on a small machine 21:40:09 :) 21:40:10 the doc was only .060 21:40:34 I just don't like buying carbide inserts... they're expensive to me... considering I can't order them locally... well I can... but it's even MORE expensive. 21:40:37 if you keep your machine tight and take care of it, oil and stuff, its gonna last 21:40:57 there is a crabide guy, crap I cant remember its name now 21:41:13 everything is inexpensive 21:41:25 I buy my carbide inserts from www.carbidedepot.com 21:41:26 im gonna go with a w style insert 21:41:28 thats it 21:41:29 they FINALLY ship to Canada now. 21:41:42 They did, stopped, and now started again. 21:41:44 such a pain. 21:42:03 I had to ship to my sister in Ithica new york.. and wait till she comes back from school to get my carbides. 21:42:04 do you make sure your tools are on center height? 21:42:09 yes. 21:42:13 I make sure. 21:42:25 are you using a positive geomerty type insert? 21:42:27 I have an multpoint turret system... or was it called a multiplex? 21:42:40 I dunno now... it's just nice, and my machining friends are jealous of it. :) 21:43:01 hahah, cool, positive may not break a chip as well, but it will take less hp to use 21:43:26 while a negative insert will be stronger and more readly break a chip, with the cost of really straining your machine 21:44:20 and oh, keep some hss bits handy, youll find at times, they will provide you with a better finish if you grind them properly 21:44:45 cause they can be run at a much lower speed so the surface footage needed is way down there 21:44:59 I have lots of HSS... I just stink at grinding. But I had to for that keyway I needed to carve out. 21:45:34 there are some simple rules to follow for it, you have a dressing ting for your grinding wheel right? 21:45:50 somewhere... [I just don't use it] 21:46:50 you need to keep your grinding wheel clean :) 21:47:23 I think I know where it is... I need a need rough wheel anywyas... I put a grove into it. 21:49:12 yeah, just practice with stuff 21:49:49 unlike you, I dont have much stock, and what I do have, is stuff like 4140 and 4340, all over 30rc 21:50:12 I dont like spending money I think is my main problem 21:51:18 http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&category=57028&item=3867566320&rd=1 <-- something I'd like... but out of my budget. 21:51:59 I cant really click and go on this console, whats that? 21:52:17 the stock I got is sitting flat on a shelf above my workbench. I realize I have lots of 3/8 to 1" of brass. 21:52:33 it's an High Speed Grinding Spindle for 45000 rpm. 21:52:49 oh yeah, how much is it? 21:52:51 With a mounting arm. 21:53:03 right now $530USD :( 21:53:06 ouch 21:53:19 that is indeed painfull 21:53:26 but a bargan if you think about it 21:53:49 just wait and watch, youll find one for 100 bucks or so 21:54:01 thats much less then a set of bearings 21:54:07 for a grinding type spindle 21:54:36 I may play machinist tonight myself and finish my x-y table up 21:55:04 my objective isn't grinding... my objective is to have highspeed milling spindle for light applications. Milling Titanium, with cutter dias of .5mm up to 1mm. At 12K rpm. 21:55:04 hey, you have gear cutters? 21:55:20 Yup. I got gear cutters. 21:55:28 do you know what the hole diameter is? 21:55:34 I can find out. 21:55:37 sec 21:55:58 Ide gladly buy them off you or any arbor type mounted tooling you dont want 21:56:05 or cant use 21:56:24 right now I have a 7/8" arbor, and a 1" im in the process of making 21:56:36 I believe they are 8mm. 21:56:45 I got 0.315" on the bore 21:56:53 oh, little bittie ones? 21:56:58 yup. 21:57:06 ah okay 21:57:07 this is a jewellers lathe. :) 21:57:31 that is soo cool 21:57:37 how is the indexer comming? 21:58:01 spindle is made... bracket mocked up in cardboard. Stock all bought. 21:58:04 to do: 21:58:20 Motor mounts / journals. 21:58:22 bracket. 21:58:30 drill and tap the spiggot for set screws. 21:58:41 drill and tap the motor coupling for set screws. 21:58:58 so I hope to be complete by the end of the weekend. :) 21:59:07 ah sweet 21:59:24 the only time consuming part is the bracket. 21:59:26 picnet has joined #emc 21:59:34 the rest could be done in a few hours if I concentrated. 22:00:12 iab 22:00:18 wb 22:00:28 never ask a blonde whats written on the side of an orange juice carton. 22:00:28 I need a tea or another coffee... cold. 22:00:47 picnet, why? hehe. 22:00:53 "concentrated" 22:00:54 I'll install emc at the faster computer tomorrow 22:01:05 the estimated time for my job was 56 minutes 22:01:12 for some 3d finishing.. 22:01:24 at 1000mm/min 22:01:32 I like blonde jokes... I'm Asian... so I have black hair. But I have a birthmark, which is a blond patch. :) 22:02:09 anonimasu, so if your making this out of foam? Are you casting it? or what's up? 22:02:26 no I am milling it out of foam.. 22:02:29 for playing around 22:02:47 and I dont want to spend 50 minutes when my machine if milling somthing with very large stepover.. : 22:02:59 because the controller dosent interpolate motion 22:03:00 :) 22:03:05 a-l-p-h-a: it's that gearknob.. 22:03:17 it should take like 5 minutes in foam.. 22:03:38 your using foam as somethign safe to machine? 22:03:43 yeah 22:03:47 cool 22:03:52 wax is neat too 22:03:53 ground-iso 22:03:59 "markiso" in swedish.. 22:04:03 it's isolation foam.. 22:04:10 bĂlue stuff? 22:04:11 sweet 22:04:12 yeah 22:04:15 stiff and nice.. 22:04:57 2 large plates was like $25 22:05:03 ive also used it, tends to break into tiny pieces and fly around the machine at high rpm, but vacuum can take care of that - > explosive particle cloud? 22:05:21 I dont think it's that a problem :) 22:05:35 but that's probably right.. 22:05:44 but well, alu-chips are dangerous too 22:05:45 :) 22:06:00 I paid $0, do you need clean sheets of it, or just test stuff? - easy to pickup from someone building a house... 22:06:12 I bought clean sheets.. 22:06:30 it was easier then to look around for somone willing to give me 22:06:38 I dont care for the price that much.. 22:06:40 i know that well :) 22:06:44 I wish I could get somthing like wax 22:06:45 :) 22:06:54 but it's even harder for me to source then aluminium 22:07:01 candles? 22:07:13 can you machine that kind of wax? 22:07:14 lol 22:07:25 freeze it first 22:07:33 parrafin.. 22:07:34 e 22:07:37 or how you spell it 22:07:49 I'd like real prototype wax 22:07:51 :/ 22:08:33 are you just testing ? blue core is probably good enough, or some machinable plastic brb.. 22:09:00 yeah, that blue stuff machines nicely.. 22:09:08 but I'd like to make some molds later on.. 22:09:40 but I could machine them out of that blue stuff and just use some thin plastic to cover it while making a fibreglass mold off it.. 22:09:45 that works too 22:10:37 as long as it machines nicely, and get a decent surface finish... 22:10:46 gezr, the other night, when I was maching some al 6061. I was using the DOC as the radius of the carbide insert I was using. It was not chipping. Still strings that were as long as whatever. I was going at maybe 300mm/min as well. I think my DOC was 0.4mm 22:10:52 how come? 22:12:00 aluminum can be stringy and easly chipping, its a play with thing 22:12:27 :) 22:12:27 mind you... going at 300mm/min at 0.4mmDOC was fun... so fast. :) heh. 22:12:37 :) 22:12:44 turning alu is funny 22:12:48 it could be that you didnt have enough doc to cause it to break on its self, or think of it as if you need to stress the metal in the chip ya know 22:14:27 http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&category=92086&item=3867837778&rd=1 wow... this is nice... but of absolutely no use to me. it's an atlas 10 spindle pully replacement 22:14:58 I wish I had a cnc lathe 22:15:07 yeah ive seen that, that would fit on my lathe 22:15:12 :) 22:15:16 well soon maybe 22:15:42 I use a timing belt pully on mine. Zero slippage. :) 22:16:23 :) 22:18:02 http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&category=25295&item=3866051983&rd=1 <-- wow. Right Angel Milling spindle. Cheap for now. :) 22:18:20 300mm/min isnt very fast, what rpm were you cutting the aly at? 22:18:27 sweet 22:18:29 :) 22:18:33 2,000 rpm I think. 22:18:40 somewhere along that line... I didn't run the tach to check. 22:18:50 cutter was what dia? 22:19:49 picnet, the turning tool is a 55deg diamond, with a radius point of 1/64" I believe. 22:20:02 ah lathe, not mill? 22:20:07 yea lathe. 22:20:27 ok. 22:20:33 i best vanish its late here, have fun. 22:22:26 wow... http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&category=58254&item=3869043964&rd=1 so easy to make. 22:22:52 can't believe this guy did that. hehe 22:23:15 but it won't have the power to mill I think. 22:23:26 now if I had 2 of thoose bearings :) 22:23:39 or 4 ;) 22:24:05 24W 22:24:10 real power :) 22:24:53 I doubt you can mill with it.. 22:25:13 I can believe engrave... but not mill. 22:25:23 yeah milling takes lots of hp.. 22:26:36 My requirements: 1IPM feedrate. Cutting diamater of 0.5mm to 1mm, DOC is 0.5mm. RPM at 12K. 22:27:35 does ti take that much speed? 22:27:48 * anonimasu havent seen anything about milling ti.. 22:27:53 just that it's tricky 22:28:21 I was told those specs by the end mill manufacturer. CET is the manufacturer. 22:28:27 I'd give a url, but I don't remember it. 22:28:33 I have their catalogue somewhere 22:29:23 dosent matter that much 22:29:43 http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&category=58254&item=3854378718 <-- not this is something of interest to me. 22:30:19 all I'd need is a nice tach to figure out my RPMs. 22:30:43 :) 22:31:00 I am so tempted to make an RPM reader... I have the schematics and everything, just not all the components. 22:31:17 a 5 digit LED/LCD counter... that'd be nice. 22:31:51 use an ATMEL chip to do my dirty work. :) 22:32:15 hmm... I just figured out how to do it. 22:32:41 atmels ar nice 22:32:42 do it on a 10second or 5 second count. For 5 seconds, count how many pulses were triggered. report that on the LCD/LED. Repeat. 22:32:44 are 22:32:51 that's way too slow 22:32:52 :) 22:33:02 it'd be accurate enough. 22:33:17 hmm ok 22:33:21 I could do it for a second... bit I couldn't get any readings lower than 60rpm. :) 22:33:28 bit=but 22:33:39 * anonimasu will be using a 0.5 sec as interval 22:34:03 with 2 pulses per rev 22:34:03 :) 22:34:09 but that's for my other project 22:36:07 but I need emc running so I can cut some alu and measure,, 22:36:33 http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&category=58254&item=3854378718 <-- I like this design, it's simple. 22:36:49 just wonder if it's beefy enough the motor. 22:37:31 yeah 22:37:40 I need to rest for a bit 22:37:47 later. 22:38:02 alex_joni has joined #emc 22:38:06 hmm... maybe I'll use a planetary gear system... [for kicks] for my spindle. hmm... 22:38:16 greetings 22:38:21 bonjourno! 22:39:31 laters 22:40:43 http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&category=58254&item=3868911769&rd=1 <-- dang this wolfgang guy has a lot of CNC systems to sell. 22:41:50 ottos has joined #emc 22:42:17 ottos has left #emc 22:46:16 * alex_joni finally set up his internet connection at home.. 22:46:26 now I can browse wirelessly with my laptop 22:46:36 even in bed .. :D 22:47:18 Mer has joined #EMC 22:48:29 Mer has quit 22:49:44 A-L-P-H-A: you can multiply the value read by the counter 22:49:55 I know. :) 22:50:04 or do some kind of average (to increase performance of the display) 22:50:11 that's what I would do.. 22:50:17 grap an ATMEL with gcc 22:50:24 in 5 mins you're done 22:50:30 my problem isn't the ATMEL to LCD display functions. 22:50:33 :D 22:50:37 I haven't played with atmels much at all. 22:50:50 though I do have 20 or so of them of the 90s2313 22:50:53 it's basic c-programming 22:50:58 90s2313 - 10mHz. 22:51:05 you just output to one pin (or port) 22:51:21 say you have an BCD-display 22:51:28 alex_joni, you play with atmels a lot? 22:51:38 I guess... 22:51:50 I played with some ATMega128 ;) 22:51:58 those are a little bigger 22:52:05 128 kB flash 22:52:10 cool... well... I just need to figure out how to make make the chip communicated with the LCD/LED screen. 22:52:19 yeah.... but how big will my app be? TINY. :) 22:52:21 LCD or LED? 22:52:30 Either... isn't the logic the same? 22:52:39 I know.. that's why a 90s2313 is the best 22:52:44 not really the same logic 22:52:57 if you have LCD, it probably has an controller on board 22:53:06 and you basicly send text to the LCD 22:53:14 write('whatever') 22:53:26 where write is the function to output to the LCD 22:53:40 you can find a lot of source code for most LCD controllers 22:53:53 try AVRLib (it has some controllers) 22:54:02 so I'd need a secondary controller, that is if the LCD/LED doesn't already have a controller. 22:54:15 not really 22:54:16 so I'd need to pins to the controller to get it down. 22:54:27 Atmel -> controller -> LCD/LED 22:54:29 if the LCD/LED doesn't have a controller you need to controll it 22:54:40 * alex_joni haven't seen an LCD without controller... ;) 22:54:57 but a lot of BCD-display (those 7-segments like in electronic watches) 22:55:06 those don't have controllers 22:55:11 but they are easy to use 22:55:12 robin_sz has joined #emc 22:55:36 meep? 22:55:42 well... I'm looking for something on the cheap. :) heh... I'll worry about the TACH at a later time. :) 22:55:53 use a 8-bit register (say 74LS245) and connect the outputs to the BCD 22:55:54 I have an tach from www.dakeng.com built already. so I'm good for now. 22:56:09 now you only need to load the value for the BCD to output into the 245 22:56:17 one 245 for each BCD you need 22:56:23 4 digits-> 4 x 245 22:56:28 ?peem 22:56:37 btw: http://hubbard.engr.scu.edu/embedded/avr/avrlib/ 22:56:55 how optimized is it? 22:57:06 avrlib? 22:57:18 I liked doing it by hand... the AVRASM. but C would be so much faster. :) heh 22:57:34 a lot faster 22:57:40 and.. you have gdb ;) 22:57:48 I use a JTAG programmer 22:57:52 and debugger 22:58:13 acemi has quit 22:58:20 Hmm... I'd need examples on how to poll a crystal, to get a proper timming/sync. 22:58:49 well.. you don't need to poll the crystal 22:59:00 you know how fast it is 22:59:14 and based on that you can calculate a timer-function 22:59:31 say.. if you have a 10MHz osc 22:59:35 The crystal forces the clock cycles on the chip though. 22:59:40 crystals lend themselves to interupts ... 22:59:43 yup 22:59:46 'ight. 22:59:57 say you program a timer 23:00:02 yeah, so I guess I don't need to do anything with the crystal other than hook it up. 23:00:06 to count x clock cycles 23:00:13 yeah, a timer .. you could poll a timer 23:00:14 and then generate an interupt 23:00:34 * alex_joni thinks that atmel might even have an counter 23:00:45 connect the signal from the spindle to the counter 23:00:53 and you need a big while 23:00:59 * robin_sz saw a nice up board this week 23:01:01 check the value of the counter 23:01:09 blackfin 23:01:17 running uclinux 23:01:25 alex_joni, hang on a sec... :) I'm writing down some thoughts. 23:01:25 cool 23:01:29 arm? 23:01:45 no ... a blackfin DSP 23:01:50 it runs linux .. 23:01:52 robin: disregard that ;) 23:02:00 using a DSP core ... weird huh 23:02:08 * alex_joni thought it's smthg else 23:02:18 linux on a DSP... 23:02:26 a lot of ideas come alive :D 23:02:51 you get a nice baord, with various IO, serial, parelallel, some sort of notwork .. 23:02:53 95 GBP 23:02:55 * alex_joni had acces to a StarCore DSP 23:03:04 that's a big DSP 23:03:24 Motorola 23:04:08 http://uk.farnell.com/jsp/endecaSearch/partDetail.jsp?N=401&SKU=8546185 23:05:17 not bad 23:12:50 alex_joni http://www.pastebin.com/231847 23:12:50 that's the logic I'm thinking of. 23:12:50 TT = TTL 23:12:50 not good... back is twiching. 23:12:50 robin: this SC I'm talking about has 4 DSP cores 23:12:50 running at 250 MHz each ;) 23:12:50 cute 23:12:50 really 23:12:50 we have an evaluation board at the local college 23:12:50 this is a single 600mhz core I think 23:12:50 with Gigabit / Gigafibre 23:12:50 they do cores to 756mhz .. thats quick enough :) 23:12:50 Mer has joined #EMC 23:12:50 nice 23:12:50 I hope it's passive cooled 23:12:50 and cheap too .. 95 GBP for that development board .. 23:12:50 yeah... 23:12:50 you don't get a SBC for 100 quid 23:12:50 and if you say it's got ethernet... 23:12:50 well. .. details are sketchy :) 23:12:50 I see that 23:13:27 http://blackfin.uclinux.org/ 23:13:49 I am already reading there 23:14:15 hmm... I guess I'm gonna have to hash through this code to learn it. :) 23:14:31 a-l-p-h-a: can't get that page to load 23:14:36 nah. I'll wait till I need to. dang. this is so much on my plate. 23:14:42 sec. 23:16:46 http://www.analog.com/en/epHSProd/0%2C%2CBF533-STAMP%2C00.html 23:16:56 yeah, it has ethernet :) and LOT more 23:18:05 alex_joni, http://www.lloydleung.com/uploads/tach_logic.html 23:18:23 that's the logic anyways. :) 23:19:01 issue I see that I'll be having is, well... the output will be flashing alot, cause the RPM may not be exact stable. 23:19:03 I kinda agree 23:19:11 but.. you might get into problems 23:19:17 exactly 23:20:06 it would be better to count an exact time.. 23:20:17 say you do a lot of nops (10.000.000) 23:20:28 that's exactly 1 second @ 10 MHz 23:20:30 I could average the RPM pulse by a stack... and average that stack. 23:20:57 that too 23:21:12 alex_joni: if you conut 1000000 nops you dont know how long that takes .. interrupts culd have happened 23:21:24 I don't know how to do a timer that is like that... in asm, I would have to manually figure out the # of clock cycles for each comment, and compute that. 23:21:33 cli 23:21:51 try gcc ;) 23:21:58 make a big for 23:22:07 you can be +/- 1% accurate 23:22:14 that isn't that important 23:23:04 robin_sz: " a networked oscilloscope " 23:23:11 this sounds nice 23:23:26 project with a blackfin 23:23:32 * robin_sz nods 23:23:43 thye have one thing very right ... 23:23:45 the price 23:24:28 if you couldnt make a 600mhz DSP into a nice pulse gen ... 23:24:42 I'm wondering what would be better, my method of monitoring the difference in ticks? and display an average... display every X seconds? or your method of count ticks? 23:25:04 A-L-P-H-A: depends on the RPM 23:25:10 Your way would be good if the RPM is higher than say 120RPM... but my way is good for all rpms. 23:25:11 at low rpm, time each rev 23:25:34 at 10000rpm, count revs per time period 23:25:52 hmm... good idea. 23:25:55 just put the logic in there. 23:26:44 you dont want interrupts at 10khz .... 23:26:52 start it off... count... if pulses are greater than see 50 pulses per second... then go secondary route (my route) 23:27:08 50 pulses per second = 3000rpm. 23:27:18 this is to get spindle speed on a lathe? 23:27:31 no, highspeed spindle that will be used on the lathe. 23:27:40 for milling titanium. 23:28:04 and you need exact control of the rpm for? 23:28:16 no, I don't need exact... I need ballpark. 23:28:21 12K rpm is my target. 23:29:47 i had some beer, a nice curry, and now a sit down with a cup of tes 23:29:49 tea 23:29:54 mmm ./. sleepy :) 23:30:18 * alex_joni is hungry 23:30:29 mmmm ... currry 23:30:51 had a chicken roti yesterday. :) 23:30:59 hit the spot really nice. 23:31:05 * alex_joni plans on making some sushi tomorrow 23:31:15 this was matta paneer 23:31:27 I am supposed to be at a friends house for ribs tonight... but I didn't want to drive to her house. 23:31:37 and it's tooo cold to do anything. 23:31:50 hmm 23:32:01 a her, and food, namely ribs and it being cold 23:32:18 * alex_joni thinks of a fireplace... 23:32:28 and a LOT of possibilities :D 23:32:47 she's a friend... we had some chemistry... but she's HER... and I'm Me... I know her quirks too well. we're close friends. that's all. 23:32:48 A-L-P-H-A : see ya tommrow pal 23:33:30 Now her sister is really really cute... but she gets annoyed way too easily. I'm actually affraid of her... 23:33:54 All 5'2" of her... 23:34:02 robin: wanna hear the latest crap I thought off? 23:34:23 k, off to machine some spacers... well. drill and tap them. shouldn't take that long. 23:34:50 Mer has left #EMC 23:35:12 drill and tap 23:35:16 she has beer too? 23:35:28 okay okay 23:35:36 gezr: lol 23:36:02 http://www.analog.com/UploadedFiles/Technical_Articles/418382427uClinuxWhiteWP_WEB.pdf 23:36:08 alex_joni: go on ... shoot. 23:36:32 I have an PDA I don't use... 23:36:44 I thought I could make a nice pendant for EMC out of it 23:36:49 heh 23:36:54 I plan to buy a CF-WLAN card 23:36:55 whats it run? 23:37:07 but it's Win-CE unfortunately 23:37:18 shrug 23:37:23 Win-CE-2002 I think 23:37:26 plenty of support for that 23:37:49 can't find a page on the net to scrap that 23:37:58 and put linux on it.. 23:38:08 seems they modified the update process so you can't do that 23:38:20 heh 23:38:30 with 2000 you could still boot off a CF 23:38:31 seel it and get a zaurus or somesuch 23:38:39 not anymore :( 23:38:45 who'd want to buy it? 23:38:49 ebay! 23:38:52 it's an Casio E-125 23:39:04 i feel strange about what I want to do or not do tonight/this weekend 23:39:17 not much ebay activity around here ;) 23:39:20 i want to ... RELAX 23:39:31 * alex_joni plans on coding a little 23:39:39 relax coding 23:40:03 I plan on meeeting up with an U18 girls netball team in a pool 23:40:30 lol 23:40:57 * alex_joni grabs a bite... 23:41:08 like so many things though ... 23:41:11 it wont happen 23:53:33 * alex_joni is back 23:57:21 I really need to get broadband... 23:57:29 this dial-up really sux ;)
