[00:00:02] <spasticteapot> Oops.
[00:00:09] <spasticteapot> ]Sorry to bother Fenn specifically.
[00:00:59] <archivist> define "know"
[00:02:08] <spasticteapot> I'm wondering if it's possible to fuel-inject a 49cc engine.
[00:02:55] <archivist> probably but not on a shoestring
[00:03:19] <spasticteapot> Ah.
[00:03:21] <spasticteapot> That's the thing.
[00:03:25] <spasticteapot> Budget of maybe....$1,000?
[00:03:29] <spasticteapot> Maybe $2,000?
[00:03:35] <spasticteapot> * spasticteapot has joined an engineering club with a BUDGET.
[00:03:44] <archivist> ah ok
[00:03:45] <spasticteapot> :)
[00:04:30] <fenn> why, as a matter of fact, I do
[00:04:46] <fenn> you can do it with a microcontroller, some transistors, and a few sensors
[00:04:58] <archivist> then, micro, sensors, and injector from a donor engine
[00:05:10] <fenn> yes, and the injector of course
[00:05:28] <fenn> i wouldnt bother with any car-engine electronics except for the oxygen sensor
[00:06:20] <dmess> i got my electronics for under 300 canadian... and its running on the bench
[00:07:40] <archivist> finding an injector that can inject smallenough enough quantities for 49cc at idle is going to be the hard part
[00:07:50] <spasticteapot> Idmess: Really?
[00:07:54] <spasticteapot> Details/pics please?
[00:08:29] <spasticteapot> archivist: What about a motorcycle engine?
[00:08:42] <fenn> instead of a 49cc?
[00:09:15] <fenn> honda F4? is fuel injected already
[00:10:00] <spasticteapot> I meant for the fuel injector.
[00:11:01] <archivist> google motorcycle fuel injector and find
[00:19:30] <spasticteapot> One person suggested direct injection.
[00:21:45] <archivist> thats diesel
[00:23:17] <archivist> but also if really pushing the envelope in economy, change the cycle
[00:24:32] <spasticteapot> Oh.
[00:24:38] <spasticteapot> archivist: Cycle?
[00:24:51] <spasticteapot> I'm going to start with a 4-stroke.
[00:25:12] <spasticteapot> You mean that odd setup - langston cycle? - they use in the Prius?
[00:25:55] <archivist> yup there was an interesting combination of engine cycles in a jap car not the prius
[00:26:21] <archivist> * archivist watching next door as well
[00:28:27] <archivist> miller cycle
[01:51:28] <BigJohnT> anyone have a clue what a video card slot marked exp1 is in a late model gateway?
[01:51:50] <BigJohnT> a pci card will not fit
[01:53:41] <jepler> exp could stand for "pci express"
[01:54:49] <jepler> there are several different forms of PCI Express motherboard connectors:
http://en.wikipedia.org/wiki/Image:PCIExpress.jpg
[01:55:25] <jepler> oops, to see what kinds those are, look at the caption in the wikipedia article:
http://en.wikipedia.org/wiki/PCI_Express#Physical_Layer
[01:55:53] <BigJohnT> thanks jepler
[01:56:44] <BigJohnT> I still can't get the on board nvida to be recognized by hardy on a new computer :(
[01:57:32] <BigJohnT> from the pics it is a pci express 16 slot
[01:57:39] <DanielFalck> I couldn't get a nvidia card to be recognized by hardy either
[01:58:05] <DanielFalck> but I am using the proprietary nvidia driver for this box now- sorry I don't have emc running on it
[01:58:12] <jepler> I don't have any nvidia video cards made in the last 4 years ..
[01:58:37] <DanielFalck> 7.10 recognized it though
[01:58:59] <DanielFalck> or made a better attempt at making it usable anyway
[01:59:22] <BigJohnT> I think I have a pci express video card at my machine shop I can try :)
[01:59:48] <BigJohnT> now that I know more about what I didn't know about it all
[04:06:58] <JymmmEMC> is hardy 8.04.1 ?
[04:08:43] <SWPadnos> Hardy is 8.04. 8.04.1 is an update to that, and is probably also called Hardy
[04:09:02] <SWPadnos> it's still Hardy, it just has a bunch of updates preinstalled
[04:09:27] <JymmmEMC> Ok, then my laptop has nvidia video and is running 8.04.1 I just had to enable the restircted drivers when it asked
[04:10:04] <SWPadnos> sure. I have fine nvidia video on my Hardy laptop as well

[04:10:53] <SWPadnos> 8700M here
[04:10:55] <JymmmEMC> and that is with amd64 too (fwiw)
[04:11:13] <SWPadnos> amd64 kernel, Intel CPU
[04:11:35] <JymmmEMC> but no paraport <snickering>
[04:11:43] <SWPadnos> nope
[04:12:28] <JymmmEMC> SWPadnos: Hey, I got two 1U servers today! Rackable (Tyan S2865)
[04:12:37] <SWPadnos> cool. those should be good boards
[04:13:11] <JymmmEMC> first sata board in the house! LOL
[04:13:25] <JymmmEMC> Now, what to do with all these MFM drives???
[04:13:33] <JymmmEMC> not to mention all the RLL ones too
[04:13:52] <JymmmEMC> ok, bbiab... dvd
[04:13:57] <SWPadnos> replace them with a USB memory stick

[04:16:54] <renesis> guys i accidentally your nc machines
[04:17:09] <renesis> * renesis ^5 renesis
[04:17:28] <renesis> i have a gf5 pos =(
[04:17:50] <renesis> i dont even know how i got it my 6600 died and this was in some failbox someone abandoned here
[04:18:10] <renesis> * renesis obviously needs a new pc machine
[04:19:19] <renesis> the 40w sempron machine with $100 system core i built for the cnc prob has more power than my workstation pc =( =( =(

[12:33:01] <anonimasu> hello
[12:38:46] <archivist> there is an Alba shaper at the local scrapyard similar to here
http://www.lathes.co.uk/shapers/
[12:39:17] <anonimasu> buy it ^_^
[12:39:36] <archivist> Im broke
[12:39:54] <anonimasu> :(8
[12:39:56] <archivist> and model engineer show on monday
[12:39:56] <fragalot> I remember those things.. only used them in HS...
[12:40:09] <fragalot> well.. abused is more like it,.. taking ~8mm off in one go... :p
[12:41:09] <archivist> and they have some of the ally extrusion that could make a router/small mill
[12:41:42] <fragalot> ok, beeing broke then sucks
[12:41:51] <fragalot> also, I can't find my cellphone charge cable and its about to die
[12:42:17] <anonimasu> hmm
[12:49:07] <fragalot> 5V source + carefully placed wires == DIY cellphone charger o.0
[12:49:14] <anonimasu> http://gfx.aftonbladet.se/multimedia/archive/00747/Canon_5200_spec_747165w.jpg
[12:49:29] <anonimasu> uh, you shouldnt charge li-ion batteries that fast ;)
[12:49:37] <fragalot> anonimasu: it's limited at 180mA
[12:49:51] <fragalot> even lower rating than the cellphone charger iirc
[12:50:03] <anonimasu> hmm.. I wonder if the charge limiting is in the cellphone or the chargers..
[12:50:13] <fragalot> both
[12:50:29] <fragalot> charger limits at what it can deliver, and the phone draws what it needs.
[12:50:33] <archivist> or in the battery!
[12:50:40] <fragalot> part of th epone :p
[12:50:46] <fragalot> anonimasu: where can I get that lens?
[12:50:56] <anonimasu> fragalot: you missed it..
[12:51:01] <anonimasu> it was on ebay..
[12:51:48] <fragalot> aww
[12:52:01] <fragalot> i love how they say that that is already 1/3rd of the nromal size
[12:52:01] <fragalot> :p
[12:52:19] <archivist> I want a canon body to go with lenses I have
[12:52:21] <fragalot> I wonder what perv bought it.
[12:52:43] <anonimasu> there are rumors that north and south korea has them ;)
[12:52:46] <anonimasu> to keep watch on eachother..
[12:52:51] <fragalot> haha
[12:53:09] <fragalot> http://a.img-dpreview.com/reviews/panasonicFZ18/images/pana_fz18_3q.jpg <-- I only have this lil' thingy,.. great price/quality ratio if you ask me,.. I paid 250euro
[12:53:13] <fragalot> new.
[12:54:14] <archivist> anonimasu, that page not loading for me :(
[12:54:38] <anonimasu> which one?

[12:55:24] <anonimasu> :D
[12:57:46] <archivist> oooooo nice toy
[13:00:15] <fragalot> lmao, crocodile dundee
[13:12:09] <fragalot> CRAP
[13:12:17] <fragalot> i forgot to make a backup of my printer settings
[13:15:43] <fragalot> and m y kernel config........... owell
[15:23:50] <maddash> usb-powered noise-canceling headphones
[15:24:32] <anonimasu> do they work?
[15:24:39] <maddash> if they existed
[15:25:08] <maddash> how freakin' hard can it be to implement? and yet, it's nowhere to be found
[15:26:35] <archivist> having a viable market is more important than difficulty to make
[15:28:42] <maddash> [sigh]
[15:29:03] <maddash> maybe the next best thing is a homemade usb-to-AAA slot converter
[15:30:44] <fragalot> maddash: been done
[15:31:08] <fragalot> usb rechargable AAA battery,.. you pop the cap off, plug it in, it charges.. put cap back on, voila! its a battery
[15:31:14] <fragalot> ... but i think it was AA, and not AAA :/
[15:31:22] <maddash> no, no
[15:31:31] <anonimasu> maddash: they do exist..
[15:31:44] <maddash> I mean a dummy that feeds into the AAA battery slot directly from USB
[15:31:48] <anonimasu> maddash: noise canceling headphones that is..
[15:31:57] <maddash> anonimasu: usb-powered?
[15:32:00] <anonimasu> yeah
[15:32:04] <maddash> anonimasu: or battery-less?
[15:32:06] <anonimasu> yes
[15:32:16] <anonimasu> I saw them about 4 years ago
[15:32:19] <anonimasu> :)

[15:37:16] <maddash_> geez, died again
[16:15:16] <JymmmEMC> maddash's AA battery powered router must need to be changed
[16:52:51] <dmess> hi all
[16:55:26] <dmess> this is better
[17:10:19] <dmess> lets see if this is any faster
[17:24:10] <Oldy> salutations
[17:33:17] <SWPadnos> hey - burlington telecom - you in Vermont?
[17:37:10] <JymmmEMC> SWPadnos: ?
[17:37:35] <SWPadnos> Oldy has a burlingtontelecom.net hostname
[17:37:42] <SWPadnos> they're in the next town over from me
[17:37:57] <JymmmEMC> ah
[17:39:22] <JymmmEMC> SWPadnos: I'm going a bit nuts here try to figure out something, Let me give the history...
[17:39:29] <SWPadnos> uh-oh :)
[17:39:37] <archivist> * archivist runs
[17:39:45] <anonimasu> * anonimasu runs too
[17:39:51] <JymmmEMC> We got in two identical laptops each having 160GB hdd. My boss screwed me up and installed a 200GB hdd in one of them. Without knowing the hdd had been switched, I Installed XP, apps, etc on the 200GB system and then imaged it using partimage and backed up the MBR using dd...
[17:39:54] <alex_joni> * alex_joni is not even here
[17:40:12] <JymmmEMC> Now, when I attempted to restore the image to the 2nd system (160GB hdd), partimage bitched about the partition being too small to restore to (and partimage cannot resize it's image to accomidate even though only 10GB is actually in use). I went back to the 200G system, used ntfsresize and or gparted, and resized the partition to 150GB, the reimaged using partiamge again...
[17:40:52] <JymmmEMC> I was able to restore the image to the second machine, no problem. And then I imaged the 2nd machine as it's the proper size. Now, when I tried to restore the image on a 3rd machine, it says it's too large 165GB to a 160GB hdd... ntfsresize resizes the ntfs volume on that partition, not the partition itself.
[17:41:26] <SWPadnos> hrm
[17:41:33] <JymmmEMC> So, somewhere in all this mess, either writing/reading from/to that's been something that's been mucked up and now I can't restore to anything. When I startup gparted it reports 145GB unpartitioned space, yet I can boot into XP. I'm at a loss here.... I even tried dd if=/dev/zero of=/dev/sda count=1M bs=1024 and it all is still screwed up. any thought or suggestions at what to look at?
[17:42:37] <SWPadnos> huh - zeroing the beginning of sda doesn't nuke the partition table?
[17:42:54] <JymmmEMC> nope
[17:43:11] <SWPadnos> as an actual hard disk or USB-attached?
[17:43:24] <JymmmEMC> real hdd
[17:43:27] <JymmmEMC> sata
[17:43:35] <SWPadnos> ok, that is odd
[17:43:53] <SWPadnos> it sure sounds like the dd isn't happening
[17:44:23] <JymmmEMC> I read a bug in libparted, but I'm not sure if it's related or not.
[17:44:56] <SWPadnos> well, if you dd'ed it and then it still booted XP, the dd isn't working the way it should
[17:44:56] <JymmmEMC> and why gparted is reporting 145GB unallocated partition, yet I can boot into XP is beyond me
[17:45:23] <SWPadnos> unless there's a secondary MBR/partition table that Linux doesn't know about (not likely0
[17:46:21] <JymmmEMC> well, I started a XP install a few minutes ago to let it recreate the partition. gonne hop into gparted as soon as I finish writing down the block info
[17:49:26] <JymmmEMC> hmmm.... hdparm /dev/sda is throwing errors.... wtf?!
[17:49:34] <JymmmEMC> oh wait...
[17:51:22] <JymmmEMC> WTH.... gparted is STILL report the hdd size as 149GB
[17:51:33] <SWPadnos> hdd or partition?
[17:51:39] <JymmmEMC> hdd
[17:51:48] <JymmmEMC> hdd 149.05
[17:51:57] <SWPadnos> gigabytes or gibibytes?
[17:52:10] <JymmmEMC> GiB
[17:52:23] <SWPadnos> that's about right for a 160GB disk
[17:52:36] <JymmmEMC> /dev/sda1 = 125.00 GiB
[17:52:45] <JymmmEMC> unallocate 24.05 GiB
[17:54:04] <JymmmEMC> SWPadnos: ok, what is gibibytes, as fdisk is reporting 154GB, which is reasonable for a formatted hdd
[17:54:14] <JymmmEMC> 160gb beign raw size
[17:55:03] <SWPadnos> gigabytes as reporeted by manufacturers are 10^9 (billions)
[17:55:11] <SWPadnos> gibibytes are 2^30
[17:55:21] <JymmmEMC> and with gparted perviosuly reporting 149Gb unallocated space, though I could boot into XP tells me it's lying to me somewhere
[17:55:55] <SWPadnos> they may report differently
[17:56:11] <SWPadnos> 149.05*2^30 is almost exactly 160*10^9
[17:56:18] <JymmmEMC> Even so.... 149 UNALLOCATED where I cna boot into XP says it's lying
[17:56:48] <anonimasu> manufacturers lie..
[17:56:53] <JymmmEMC> unallocated, as in no partitions exist at all, yet can boot into XP
[17:56:53] <SWPadnos> I wonder if they're doing something weird with LBA or something
[17:57:16] <anonimasu> is this a old hdd? there might be alot of broken blocks that's been flagged
[17:57:22] <SWPadnos> I thought you said there was a 125G /dev/sda1
[17:57:38] <SWPadnos> no, a 160GB notebook drive isn't too old ;)
[17:57:46] <JymmmEMC> There is, as reported in fdisk, but not gparted
[17:58:09] <JymmmEMC> anonimasu: These are BRAND new Dell E6400's 19hour battery life =)
[17:58:33] <anonimasu> ok
[17:58:34] <JymmmEMC> anonimasu: nineteen hours baby =)
[17:58:52] <anonimasu> hm.. seems like a cheap laptop too :)
[17:59:05] <JymmmEMC> actually it's not bad
[17:59:11] <JymmmEMC> anywho...
[17:59:30] <anonimasu> though heavy
[17:59:30] <JymmmEMC> Ok, what tool can I use to confirm nobody is lying to me?
[18:00:16] <JymmmEMC> ntfsresize resizes the ntfs VOLUME, not the actual partition.
[18:00:39] <JymmmEMC> gparted does resize partitions, but it's definatly lying to me what it's reporting anyway.
[18:02:05] <SWPadnos> is there any data you need to keep, or can you wipe the disk?
[18:02:20] <JymmmEMC> screw it... dd if=/dev/zero of=/dev/sda
[18:02:36] <anonimasu> I dont think you should DD it clean.
[18:03:05] <JymmmEMC> SWPadnos: No, my whole intension is to not have to rebuild the pristeen image all over again.
[18:03:16] <JymmmEMC> just get the sucker on the hdd
[18:04:00] <JymmmEMC> anonimasu: why not?
[18:05:06] <anonimasu> I cant remember where I read something about it..
[18:05:23] <JymmmEMC> if one of the utilities I used has a bug in it, and wrote/reading something funky along the way, and clearing out the MBR didn't work, I know of no other way to 100% "without a doubt" clear the drive and "start over"
[18:05:59] <SWPadnos> you should be able to do it with a single zero sector
[18:06:05] <SWPadnos> dd if=/dev/zero of=/dev/hda bs=512 count=1
[18:06:31] <JymmmEMC> SWPadnos: I should, but remember I did bs=1024 count=1M and that didn't do it either
[18:06:36] <SWPadnos> you may need sudo, but I'd expect an error if permissions stopped the write from happening
[18:06:38] <SWPadnos> sure
[18:06:46] <SWPadnos> and be syre to sync afterwards
[18:07:03] <JymmmEMC> ?
[18:07:06] <SWPadnos> also, be sure that none of the partitions are mounted
[18:07:18] <JymmmEMC> booting off a sysresccd
[18:07:26] <SWPadnos> if you dd, then pull the plug, then the sectors may never be written to disk
[18:07:46] <JymmmEMC> how to sync after it's done?
[18:07:54] <JymmmEMC> hdparm -z /dev/sda ?
[18:07:55] <SWPadnos> "sync" in a terminal ;)
[18:08:06] <anonimasu> "sync"
[18:08:07] <anonimasu> :)
[18:08:19] <SWPadnos> that shouldn't return until all pending writes ahve completed
[18:08:21] <SWPadnos> have
[18:08:44] <JymmmEMC> bbiab, I promised to make breakfast this morning... please I'll have lots of wait time for dd to finish
[18:08:52] <JymmmEMC> s/pleae/plus/
[18:08:56] <Oldy> sorry SWPadnos I was away for awhile...but yes i'm right in burlington
[18:08:56] <anonimasu> :)
[18:09:07] <SWPadnos> cool - I'm in Exssex Junction
[18:09:11] <SWPadnos> err - you know ;)
[18:09:44] <SWPadnos> how long have you been in this area?
[18:10:58] <Oldy> 2 and a half years or so
[18:11:12] <SWPadnos> ah, so it's possible that we don't know each other :)
[18:13:55] <jmkasunich> lol
[18:14:16] <jmkasunich> has it snowed yet there?
[18:14:31] <SWPadnos> not at my house, but we definitely had a hard frost last night
[18:16:00] <jmkasunich> 44 here this morning
[18:16:09] <jmkasunich> I think its in the mid-50s now
[18:16:09] <SWPadnos> around 20-25 here
[18:16:17] <SWPadnos> yeah, we're supposed to get that high today
[18:16:23] <SWPadnos> well, 50 anyway
[18:16:28] <jmkasunich> 20-25?
[18:16:42] <SWPadnos> yeah, this morning at 9:00 or 10:00
[18:16:46] <jmkasunich> that is a seriously hard frost
[18:16:50] <SWPadnos> heh
[18:17:16] <SWPadnos> I had to wear a sweater
[18:17:22] <jmkasunich> I haven't drained and put away the hose yet, if I was where you are it would be frozen solid
[18:17:47] <SWPadnos> yep. we did that when we had a cold snap a month or so ago
[18:17:55] <jmkasunich> on a totally unrelated note, I'm running out of excuses for not building my gantry mill
[18:17:58] <SWPadnos> then it got up into the 70s-80s again
[18:18:02] <SWPadnos> heh
[18:18:03] <jmkasunich> got the X and Y rails, and the X ballscrew today
[18:18:18] <SWPadnos> hmmm. should I try to retrofit the BP before you build a second mill?
[18:18:25] <jmkasunich> yeah
[18:18:29] <SWPadnos> cool. good deals at HGR?
[18:19:04] <jmkasunich> 42" rail with 2 cars, $50, 25" rails with two cars, $35, 40ish long THK ballscrew with nut, $75
[18:19:13] <jmkasunich> got two of each rail
[18:19:14] <SWPadnos> I do have a big-ass enclosure that I think might actually be big enough for all the electronics
[18:19:22] <SWPadnos> nice
[18:19:30] <jmkasunich> I have some big-ass capacitors in the garage now
[18:19:35] <SWPadnos> coooool
[18:20:01] <jmkasunich> I haven't figured out if the ballscrew is rolled or ground
[18:20:23] <SWPadnos> the only way I know to tell is whether the top ridges are flat or have a sort of groove in them
[18:20:50] <fragalot> big capacitors you say?
[18:20:58] <SWPadnos> this is my control cabinet now:
http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=7614382991
[18:21:00] <fragalot> why do I always link "big capacitors" to "coilgun" ?
[18:21:11] <SWPadnos> (planned control cabinet anyway)
[18:21:18] <SWPadnos> because you're a violent youth
[18:21:21] <jmkasunich> fragalot: cause you like sparks and loud noises
[18:21:26] <fragalot> jmkasunich: don't you?
[18:21:42] <SWPadnos> this isn't about him
[18:21:45] <SWPadnos> this is about you
[18:21:47] <jmkasunich> 7 of the caps I got would be especially suitable to a coilgun
[18:21:53] <fragalot> SWPadnos: looks sturdy,... also,.. 5 locks? o.0
[18:21:57] <jmkasunich> 5600uF at 575VDC, 900ish joules
[18:22:01] <jmkasunich> (each)
[18:22:13] <SWPadnos> yeah, the locks are a pain, but I hope to not open it too often
[18:22:15] <fragalot> jmkasunich: yeah, that would work =D
[18:22:25] <fragalot> SWPadnos: /OR/ you can just leave 4 out of 5 locks open :p
[18:22:34] <SWPadnos> heh, too wasy
[18:22:37] <SWPadnos> easy too
[18:22:41] <dmess> i worked in the mines up north for 6 yrs... i like Ammex and stick glycerine
[18:22:46] <fragalot> ok
[18:22:58] <SWPadnos> ka-boom-ski
[18:23:22] <fragalot> SWPadnos: take the locks out, but do it on a drill press, after that, cut out circles of sheet metal on a lathe, then weld those in, polish and repaint the cabinet..... hard enough?
[18:23:41] <SWPadnos> it would be a lot easier to just remove the nuts from the back - no drilling needed
[18:23:47] <dmess> aaahhh i LOVE the smell of cordite in the morning
[18:23:59] <SWPadnos> since I don't know how to weld, it wouldn't be quite as easy
[18:24:13] <fragalot> SWPadnos: yes, but it's TOO EASY to take the nuts out.
[18:24:20] <SWPadnos> but it is NEMA 12, and to keep the seal working it does need latches in several locations
[18:24:25] <SWPadnos> har har :)
[18:24:27] <fragalot> welding isn't really that hard,.. easy to pick up
[18:24:52] <fragalot> hell, even I can weld. :p
[18:25:19] <SWPadnos> oh, then I can definitely do it :)
[18:25:32] <SWPadnos> I just never have - I have a regulator set a friend gave me
[18:26:08] <jmkasunich> swpadnos: I've seen the "groove on crest" rolled screws
[18:26:20] <jmkasunich> this one has a somewhat different looking groove, which made me unsure
[18:26:28] <fragalot> I have a TIG/SMAW inverter, and a bigass .. well.. basically it's just a coil laying about that was here when we bought the house.
[18:26:28] <jmkasunich> but I'm thinking it might be ground
[18:26:38] <SWPadnos> hmmm. I don't know any other way to tell
[18:26:40] <jmkasunich> here's the nut (it has a part number, the screw doesn't)
[18:26:42] <jmkasunich> https://tech.thk.com/en/products/thk_cat_main_five.php?id=2452&st=Qk5U&ss=MzA=&tt=MA==
[18:26:49] <jmkasunich> https://tech.thk.com/en/products/get_all_attributes.php?id=2452
[18:27:03] <jmkasunich> the second page says "shaft process method: precision"
[18:27:15] <SWPadnos> it's possible to roll most of the thread, then grind the final - that might result in a small groove on the flats
[18:27:25] <SWPadnos> (grind the final thread and OD)
[18:27:32] <jmkasunich> this groove is wide and shallow
[18:27:38] <SWPadnos> oh, that's odd
[18:29:07] <jmkasunich> I just noticed the navigation bar at the top of the page Ballscrew->Precision->blah
[18:29:16] <jmkasunich> Ballscrew->Rolled is a differnet catagory
[18:29:23] <SWPadnos> yep
[18:30:48] <SWPadnos> I have sites that open every friggin link in a new window
[18:30:52] <SWPadnos> s/have/hate/
[18:31:46] <jmkasunich> 10mm pitch - a wee bit finer would have been nice, but that should be OK
[18:33:49] <SWPadnos> long, short, or both?
[18:34:00] <fragalot> look at it from the bright side.. atleast your machine 'l be faster... :p
[18:34:13] <jmkasunich> SWPadnos?
[18:34:23] <jmkasunich> this is the screw for the long axis
[18:34:26] <SWPadnos> are they all 10mm pitch, or just some of them
[18:34:28] <SWPadnos> ok
[18:35:31] <jmkasunich> I only got one screw today
[18:35:47] <jmkasunich> I already had the Y screw, it isn't a THK, and is 0.200 pitch
[18:36:34] <jmkasunich> the Y is dual circuit, and I think it preloaded
[18:36:50] <jmkasunich> I think it was rebuilt - it is nicely wrapped and has the insepection certificate with it
[18:37:21] <jmkasunich> the one I got today also still has THK wrapping paper around most of the length
[18:38:22] <KimK_IA> Anyone use QCad? I'm new to it and when I make a mistake and delete(?) what I did, it apparently leaves something behind (a dimensionless point?) that I can't select or more importantly, get rid of. What am I doing wrong?
[18:39:11] <DanielFalck1> is it really a point or is it just an indicator of where the cursor was?
[18:39:25] <KimK_IA> I don't know. How can I tell?
[18:39:42] <jmkasunich> pan the drawing till its offscreen, then pan back, is it still there?
[18:40:05] <KimK_IA> I have tried redraw, but hold on...
[18:40:24] <KimK_IA> Yes
[18:40:28] <KimK_IA> still there
[18:40:56] <DanielFalck1> it moves around though
[18:41:11] <DanielFalck1> it's a function of the last cursor position
[18:41:27] <KimK_IA> It moves offscreen while I'm panning, then moves back when I unpan(?)
[18:41:44] <DanielFalck1> I don't think it's a real entity
[18:42:32] <KimK_IA> Is it telling me something useful, or is it just a bug? (Or an inducement to buy the paid version?)
[18:42:52] <DanielFalck1> it's probably what the author thought was a useful feature
[18:43:05] <DanielFalck1> it's not useful to me though
[18:44:09] <KimK_IA> OK. There doesn't seem to be a way to change the "command line" (QCad's) to inch entry. Is there a trick? INI file, maybe?
[18:44:33] <DanielFalck1> Edit/ Application Preferences
[18:44:42] <DanielFalck1> Defaults
[18:45:35] <KimK_IA> I've got tab 1 & 3 on English, still MM.
[18:46:38] <DanielFalck1> in the 'Defaults' tab there's a setting for inch
[18:46:54] <DanielFalck1> Version 2.0.5.0 here
[18:48:05] <DanielFalck1> you can also switch the 'current drawing preferences' from the edit menu too
[18:51:39] <KimK_IA> OK, thanks. It still has a bias for mm. For example in paper selection, even letter & legal show in mm.
[18:51:50] <DanielFalck1> hmm ok
[18:52:09] <DanielFalck1> I use it to do quick dxf files to export into other things
[18:52:16] <DanielFalck1> I don't use it for much else
[18:53:06] <KimK_IA> I was trying to get its command line to accept inches/decimal/mils, but I guess I can use Ubuntu's calculator and 25.4.
[18:53:51] <KimK_IA> Is the paid version improved?
[18:57:14] <DanielFalck1> I couldn't tell you on that
[18:58:27] <anonimasu> KimK_IA: the point you see might be a artifact, try redrawing your screen
[18:58:43] <jmkasunich> anonimasu: mentioned a while ago ;-)
[18:58:50] <anonimasu> ah sorry I missed that :)
[18:59:17] <JymmmEMC> Ok, the masses have been fed =)
[18:59:30] <KimK_IA> no problem, I need all the help I can get
[19:00:24] <archivist> I is still hungry JymmmEMC :)
[19:01:25] <JymmmEMC> archivist: Um, why didn't you put in your order... I made Eggs Benedict.
[19:01:59] <skunkworks> we just had 3rd day turkey meal leftovers. It just keeps getting better and better
[19:02:32] <JymmmEMC> skunkworks: are you starting to look/feel like a turkey now?
[19:03:00] <fragalot> skunkworks: I thought I smelled something
[19:03:23] <JymmmEMC> I like turkey leftovers, esp turkeu sandwich, but after three days... I need a change of pace
[19:04:22] <KimK_IA> I found this on QCad's professional (paid) vs. community (free) editions:
[19:04:24] <KimK_IA> 35. What's the difference between the free QCAD Community Edition and QCAD Professional?
[19:04:25] <KimK_IA> There is no scripting support and little polyline support in the Community Edition. The Community Edition is significantly older than QCAD Professional and therefore contains less features. The QCAD Community Edition is not available for Windows.
[19:05:12] <JymmmEMC> KimK_IA: you need it on windows?
[19:05:43] <jepler> huh, I just got a "joint 1 following error" (pluto_step).
[19:06:19] <KimK_IA> JymmmEMC: No thanks, trying to quit
[19:06:30] <JymmmEMC> jepler: "what ya trying to go 4,000,000 IPM for?" =)
[19:06:46] <jepler> actually it was moving fairly slowly (F8 inches?) at the time
[19:06:56] <JymmmEMC> jepler: ewwwwww
[19:07:05] <JymmmEMC> that not very nice if it, was it.
[19:07:10] <JymmmEMC> s/if/of/
[19:07:23] <JymmmEMC> KimK_IA: The right tool for the job.
[19:07:26] <jepler> must be a bug .. too bad I wrote this driver and have no one else to blame it on
[19:08:07] <JymmmEMC> jepler: That's not true... you could blame it on SWPadnos. You know he always has something to do with something or another
[19:08:50] <fragalot> Blame the dog.
[19:08:56] <JymmmEMC> "Why is grass green, it's SWPadnos' fault!"
[19:11:04] <JymmmEMC> jepler: I know you were playing with pluto at one time, but I dind't know you were still working on it, thought something different/better had come along.
[19:11:37] <KimK_IA> JymmmEMC: I used to use TurboCAD Professional on Windows, that worked very well, and much more affordable than AutoCAD. But now trying to use Ubuntu for everything except an IE-only website for work. And I hope VMware will fix that someday.
[19:12:08] <jepler> JymmmEMC: there is other hardware I'd recommend, but this is the hardware I own
[19:12:17] <JymmmEMC> jepler: Ah, gotcha =)
[19:12:55] <DanielFalck1> jepler: what would you recommend these days?
[19:12:59] <jepler> oops, emc managed to stop without hurting the tool when it got the following error .. but then I broke it off when I used MDI and forgot to enter "G1"
[19:13:02] <jepler> sigh
[19:13:07] <JymmmEMC> KimK_IA: I like vmware alot... Hasn't been an issue with me so far.
[19:13:12] <DanielFalck1> for a servo system
[19:13:18] <jepler> DanielFalck1: I think mesa is the best choice
[19:14:05] <jepler> DanielFalck1: particularly if you want to interface with +-10V analog servos it seems to be a nice complete package
[19:14:08] <JymmmEMC> jepler: oh man.... that bites. Maybe time to walk away for a bit? kick the "perverbial" dog, grab a cup of [insert favorite poison here] ?
[19:14:12] <DanielFalck1> I have a Centroid controlled Bridgeport and I want to change it over to emc2
[19:14:18] <jepler> JymmmEMC: yeah I'm about to
[19:14:23] <JymmmEMC> jepler: =)
[19:14:52] <jepler> (it's not a particularly expensive tool .. less than ten bucks)
[19:15:03] <DanielFalck1> the servo amp box is Centroid manufactured and I want to save the servo motors/power supply relays etc...
[19:15:06] <JymmmEMC> jepler: still, I hate when that happens
[19:15:18] <jepler> JymmmEMC: agreed and thanks for the sympathy
[19:16:53] <JymmmEMC> jepler: Yeah, lately it seems like everything is fubaring at once (on this end)... Just walk away, don't scream, dont throw across room, just walk away... =)
[19:17:07] <jepler> DanielFalck1: only problem with mesa is if you run out of I/O points. The usual setup with the m5i20 board is 3 axes + spindle + 16 out + 32 in. mesa has new add-on cards for higher I/O counts but emc doesn't have support in its driver quite yet
[19:18:35] <DanielFalck1> jepler: thanks for the info
[19:18:53] <JymmmEMC> a spare 16 sounds like a lot, even if you added 2 more axises
[19:19:02] <DanielFalck1> right now I have 4 axis and a small amount of i/o
[19:19:33] <DanielFalck1> spindle on/off forward/reverse
[19:20:02] <KimK_IA> I'm looking at Mesa too. Any recent news on progress of hostmot2?
[19:21:31] <jepler> KimK_IA: I know Seb Kuzminsky is actively working on it. I haven't followed the recent threads, but I think he's ironing out the problems as they're reported
[19:21:52] <fragalot> who in here was I talking to about the cabinets that raise up from under the floor? -->

[19:30:26] <fragalot> jepler: lol.
[20:02:28] <JymmmEMC> hmmm.... I wonder if I should sell my tapping head, I've never used it since I got it, but I haven't tapped anything since then either - intensions were to add it to the cnc router
[20:10:59] <BigJohnT> JymmmEMC: what kind of tapping head do you have?
[20:11:46] <JymmmEMC> tapmatic 30 TC/DC
[20:12:46] <crotchet> Hi guys- non-electronics guy question- what do you guys use to de-solder components? I have some bad caps to take out of a monitor power supply and I wasn't impressed with how a desolder bulb worked.
[20:13:04] <JymmmEMC> solder wick
[20:13:32] <BigJohnT> solder sucker
[20:13:54] <crotchet> JymmmEMC: any particular spec?
[20:14:03] <crotchet> never used solder wick
[20:14:04] <JymmmEMC> not used?
[20:15:06] <JymmmEMC> solder wick is basically braided copper with flux in it. Just got the diameter that is slightly larger than the largest pad you'll be working on
[20:15:12] <JymmmEMC> s/got/get/
[20:15:20] <JymmmEMC> s/diameter/width/
[20:15:32] <crotchet> JymmmEMC: thanks- I'm ordering now-
[20:15:59] <fragalot> * fragalot hugs his desolder station
[20:16:08] <JymmmEMC> crotchet: you dont have a radio shack near you?
[20:16:20] <fragalot> damnit i forgot to mount /boot before putting my kernel in
[20:16:21] <fragalot> >.>
[20:18:49] <crotchet> JymmmEMC: I'm ordering off Mouser electronics-the caps, so figured I'd get something to de-solder with. Radio shacks around here didn't have anything close to what I needed in caps
[20:19:11] <JymmmEMC> crotchet:
http://www.radioshack.com/product/index.jsp?productId=2062744&cp=2032058.2032236.2032313&parentPage=search&kw=soldering+iron&fbc=1&fbn=Type%2FFlux&pg=2&parentPage=family
[20:20:39] <JymmmEMC> hmmm, nice to know that RS has silver solder now.
[20:20:48] <crotchet> thanks again, JymmmEMC-
[20:21:11] <JymmmEMC> crotchet: Eh, I'm one for not like to order things if I don't have to. If I can find/use a local resource instead I much rather go that way.
[20:22:35] <crotchet> I tried radio shack first, but the caps were a tight fit, and wouldn't fit in the space, so I had to get real specific.
[20:23:32] <JymmmEMC> I understand... RS doens't have crap anymore, but when they DO have something, I like to go that route as I know if I need more, I can just run down the street on a Sunday and get it.
[20:24:15] <crotchet> ever tried Mouser? seem like a nice resource?
[20:24:32] <crotchet> http://www.mouser.com
[20:25:24] <JymmmEMC> Take fuses as example.... That are a zillion different types, sizes, etc... I'd much rather spend a lil more and get a fuser holder that will do what I need and be able to hit the local HW store, auto parts, or even the grocery store in some cases and get a replacement fuse.
[20:25:47] <crotchet> even sent me a huge catalog for the measly 5 caps I used for my first purchase from them
[20:26:28] <JymmmEMC> Pretty much ebay is my ONLY "mail order" that I have ever done.
[20:26:57] <JymmmEMC> There are just way to many headaches and inconvienances if they ship the wrong item, it's defective, etc
[20:27:21] <jtr> crotchet: solder sucker
http://www.mouser.com/Search/Refine.aspx?Keyword=801-DP-200
[20:27:54] <jtr> here's a picture:
http://www.jonard.com/jonard-ecommerce/control/product/~product_id=10063
[20:28:30] <JymmmEMC> they have those at RS too
[20:28:40] <JymmmEMC> before of quality
[20:28:43] <JymmmEMC> beware
[20:28:57] <JymmmEMC> inspect before you buy (just in case)
[20:29:14] <jtr> I've used both those and solder-wick - sometimes one works better than the other. I order lots of stuff from moouser and like them.
[20:29:24] <jtr> s/moouser/mouser/
[20:29:37] <JymmmEMC> It's not Mouser, it's ANY mail order thing for me
[20:30:05] <JymmmEMC> * JymmmEMC don't do mail order, period (except ebay)
[20:30:50] <JymmmEMC> but I have a lot of resources in this area too
[20:31:28] <crotchet> jtr: I'll probably stick with wick- I'm not that much of a hobbyist- yet, anyway
[20:32:57] <jtr> OK industries is/was a good brand. Get an extra tip - I used to cut a little notch in the side of the tip so the iron could reach the pad while the tip was in place.
[20:34:41] <jtr> crotchet: I understand. The price is kinda steep, but worth it if you use it enough.
[20:51:44] <maddash> whooooooo 500KSamps/sec
[20:56:11] <maddash> meh the previous one advertised 52Ksamps/sec, was actually ~26785KSamps/sec
[21:08:26] <maddash> woohoo, 20 minutes without a single disconnect
[21:14:47] <dmess> good for you Maddash... my record is 92 days
[21:51:28] <dmess> should i try the VDF driver tonite or NOT...???? who's gonna be around cause i'm bound to need assistance
[22:18:21] <maddash> "When running the A/D converter in Internal Reference mode, the gain error is 3-4 LSb and the offset error is 1-2 LSb across voltage and speed. " <-- any clues on what "3-4 LSb" means? least significant bytes?
[22:18:47] <archivist> bits not bytes
[22:19:14] <maddash> bits*
[22:20:03] <maddash> so does this mean that the ADC conversion result will be 2^3 to 2^4 off?
[22:20:35] <archivist> yes
[22:21:09] <maddash> if the ADC were 10-bit, is this equivalent to saying that only the upper 6 bits are usable?
[22:21:17] <archivist> yup
[22:21:40] <maddash> so wtf is this guy talking about?
http://forum.microchip.com/tm.aspx?m=375462&mpage=1񛭭
[22:24:27] <skunkworks> ok - how the heck do you reply to a comment on youtube?
[22:24:52] <maddash> haha...by meditating on the idea, first.
[22:24:58] <archivist> no idea I havne got one yet
[22:25:03] <skunkworks> I hit reply and type a bit and press 'post comment' and it never shows up.
[22:25:14] <maddash> first you have to log in?
[22:25:20] <skunkworks> I am logged in
[22:25:30] <skunkworks> I just must be stupid.
[22:25:30] <archivist> does it get emailed
[22:25:37] <maddash> er, javascript is enabled and such?
[22:26:00] <maddash> try logging out and then directly hitting reply while logged out
[22:26:27] <skunkworks> I should ask - there are no replies - right?
http://www.youtube.com/watch?v=eUmFKOVepYY
[22:27:10] <maddash> oh, are you samcoinc?
[22:27:19] <maddash> no replies
[22:27:26] <skunkworks> ok
[22:27:52] <maddash> worst case scenario, launch a second comment thread
[22:29:40] <skunkworks> just odd.
[22:30:02] <maddash> I could help you...
[22:30:22] <maddash> I could help you leave a comment
[22:31:07] <skunkworks> heh - good idea
[22:31:10] <skunkworks> :)
[22:31:10] <maddash> oh geez...
[22:31:36] <maddash> well, you wouldn't be so sarcastic if leaving a reply was of vital importance
[22:32:10] <skunkworks> I am half expecting 4 replies to show up in a day or 2 ;)
[22:32:48] <maddash> what chips are on that pcb?
[22:33:27] <skunkworks> http://www.electronicsam.com/images/KandT/servostart/schemagain.png
[22:33:37] <maddash> do you work for lockheed or something?
[22:34:05] <skunkworks> uh - no
[22:34:22] <skunkworks> what would give that idea?
[22:34:26] <maddash> such pretty chips -- so simple, no surface mounting crud
[22:34:37] <skunkworks> heh - mostly what I had on hand
[22:34:41] <maddash> http://www.google.com/search?q=skunkworks
[22:34:42] <skunkworks> and easy for me to use
[22:35:57] <skunkworks> no. Long story short - I have a stealth Twin turbo.. (made by dodge/mitsubishi) and I have used skunkworks in relation to that for ages. crazy I know
[22:36:57] <maddash> darn. thought you were a secret agent from the advanced project division.
[22:37:25] <skunkworks> ;)
[22:39:55] <maddash> omg did xemet implement nurbs for emc2?

[22:42:19] <skunkworks> I don't think it ever made it into emc2... But I could be wrong.
[22:47:58] <dmess> thats ME
[22:50:18] <dmess> show the code..
[22:51:05] <dmess> what does the g-code look like??
[23:00:06] <maddash> the future of fabrication lies with 3dprinting, not machining...
[23:00:15] <maddash> subtractive machining*
[23:01:03] <JymmmEMC> maddash: Yeah? Lets see you "3D Print" aluminum biotch! =)
[23:02:03] <dmess> your DREAMING
[23:02:09] <archivist> they 3d printing solid metal now
[23:02:14] <archivist> ther are
[23:02:49] <dmess> yes i have Ti piece in the shop... its porous..
[23:03:08] <maddash> i'm thinking of hacking some single-cell eukaryote to secrete macroscopic structures -- switching, say, glycogen for Al shouldn't be much of an issue
[23:03:12] <dmess> its a liik alike of the part and material
[23:03:17] <dmess> look
[23:03:21] <archivist> for certain values of solid :)
[23:03:59] <archivist> I saw some at a cad/rapid prototyping show
[23:04:06] <maddash> actually, i should revise my statement: the future is additive, not subtractive
[23:05:26] <dmess> as i said.. its porous though.. ive donw Powdered metal too i know what your up against
[23:05:40] <JymmmEMC> maddash: Fine, but I still want to see you 3D Print an intake manifold!
[23:05:56] <dmess> i could...
[23:05:57] <anonimasu> what's so fancy about them?
[23:06:06] <maddash> JymmmEMC: :) star trek replicators ftw
[23:06:19] <dmess> in baking powder and epoxy
[23:06:22] <JymmmEMC> maddash: but they aint a 3D Printer now, are they =)
[23:06:51] <dmess> we have a 3-d scanner works with catia models
[23:07:21] <archivist> I have a 3d printed adjustable spanner here
[23:07:37] <maddash> archivist: pics or gt*o?
[23:07:50] <dmess> builds the model in a dish of powder
[23:07:52] <maddash> actually, just pics would be nice
[23:08:49] <dmess> when its done you remove gently and coat
[23:10:52] <maddash> http://www.evilmadscientist.com/article.php/candyfab
[23:11:12] <maddash> that one's old, but it's stuck in my head
[23:15:18] <archivist> http://www.archivist.info/cnc/p1010267.jpg and 8 and 9
[23:15:33] <anonimasu> http://www.youtube.com/watch?v=khyZI3RK2lE&feature=related
[23:15:40] <anonimasu> holy crap.
[23:17:26] <maddash> archivist: what material is that?
[23:17:50] <archivist> plastic/resin ish
[23:18:07] <JymmmEMC> archivist: You REALLY need to get on more channles than JSUT #emc
[23:18:21] <maddash> anonimasu: haha, "hi there"
[23:19:31] <archivist> the dark in the jaw is the support material during the built im supposed to dissolve out with meths
[23:20:07] <archivist> JymmmEMC, proof Im live of IRC
[23:20:15] <archivist> of on
[23:21:33] <maddash> archivist: are you sure this was printed, not milled/subtractively-fabricated? i see parallel lines on the spanne rhead
[23:23:49] <archivist> maddash, yes Im sure its a 3d rapid prototype additively made
[23:24:28] <roberth> when they 3D built up a alot of small layers isnt it over time. y you get a layer effect on some ends
[23:24:28] <archivist> note the worm is impossible
[23:24:36] <JymmmEMC> archivist: does it work?
[23:25:04] <archivist> JymmmEMC, not yet the support gunge is still in the gaps
[23:25:49] <archivist> dark in the pic (most cleaned off by hand)
[23:27:00] <maddash> crap
[23:27:10] <maddash> reading this candy fab stuff is making me hungry
[23:27:29] <archivist> this is the machine that made the spanner
http://www.capinc.com/pages/products/dimension3dprinter.cfm
[23:28:12] <archivist> ABS plastic
[23:54:20] <maddash> some of these embedded guys are real boneheads
[23:54:46] <archivist> heh just got one in ##asm
[23:55:41] <archivist> "help me make chronometer in asm" for Z80
[23:56:17] <maddash> http://forum.microchip.com/tm.aspx?m=375462&mpage=2 look at MBedder's reply to my post...
[23:57:24] <dmess> bonne chance...
[23:59:16] <maddash> seriously, what have I gotten wrong? doesn't "gain error is 3-4LSb" mean that there's a +/-8 to +/-16 error in gain?
