[00:20:31] <seb_kuzminsky> ooh, the shiny! http://www.spacex.com/panorama/index.html
[00:26:47] <A2Sheds> wasn't there support for USB for non-realtime signals somewhere?
[00:37:01] <seb_kuzminsky> A2Sheds: Jeff Epler has a non-realtime driver for the arduino
[00:37:30] <seb_kuzminsky> i think skunkworks is using it successfully
[00:40:06] <A2Sheds> I ask in 10 hours
[00:40:11] <A2Sheds> I'll
[00:41:32] <seb_kuzminsky> A2Sheds: http://axis.unpy.net/01198594294
[00:41:59] <seb_kuzminsky> i'm not sure if there have been changes to it since then, or if that's the updated version, or what
[00:47:02] <A2Sheds> thanks
[00:51:29] <A2Sheds> http://www.pjrc.com/teensy/teensyduino.html very similar
[03:11:25] <Loetmichel> mornin'
[05:39:33] <mrsun> hmm, what am i doing wrong when like 10 cycles of scraping the same side does not change the height of that side :P
[05:43:15] <alex_joni> wrong measurement?
[05:47:05] <Jymmm> mrsun: You can now scrap with something other than Play-Dough. Thank you and have a nice day.
[05:47:28] <mrsun> Jymmm, huh ? :P
[05:47:29] <alex_joni> howdy Jymmm
[05:47:36] <mrsun> alex_joni, its repeatable atleast :P
[05:48:00] <mrsun> 0.05 to high in one corner 0.06 to high in the other corner, thats mm
[05:48:18] <Jymmm> Howdy alex_joni
[05:48:59] <Jymmm> mrsun: Just slip a sugar packet under the leg ;)
[05:49:23] <mrsun> Jymmm, what?½!
[05:49:25] <mrsun> :P
[05:49:32] <Jymmm> lol
[05:54:14] <Jymmm> alex_joni: I've had this for about a month, LOVE IT! I was even able to drive down the freeway and see all four lanes by it alone... http://www.dealextreme.com/p/ultrafire-th-t60-ha-ii-xm-lt60-5-mode-1200-lumen-white-led-flashlight-with-strap-1-x-18650-57007
[05:56:20] <Jymmm> alex_joni: I got it along with these batteries: http://www.dealextreme.com/p/trustfire-protected-18650-3-7v-true-2400mah-rechargeable-lithium-batteries-2-pack-20392 and this charger: http://www.dealextreme.com/p/dsd-18650-cr123a-charger-black-936
[05:59:06] <Jymmm> alex_joni: I'm thinking of ordering this holster (I think it's the correct size for it) http://www.dealextreme.com/p/pt-004-flashlight-holster-black-106539
[06:20:22] <jthornton> dang cardboard door fell down last night
[06:20:34] <Jymmm> Mt Lion?
[06:22:47] <Jymmm> jthornton: racoon?
[06:23:50] <jthornton> faulty thumb tack
[06:25:02] <Jymmm> heh
[06:40:40] <alex_joni> Jymmm: looks nice
[06:40:57] <MattyMatt> is 10.04 still the current one? how long until 12.x?
[06:41:28] <Jymmm> alex_joni: Yeah, you kinda get used to the 5 Modes after a while, even if you dont care for them.
[06:42:12] <Jymmm> MattyMatt: 7days, 5 hours, and 19 seconds.
[06:42:45] <MattyMatt> hmm, my ssd might take that long to arrive
[06:43:07] <Jymmm> Oh yeah, and 203 years too
[06:43:51] <Jymmm> MattyMatt: So, 203 years, 7days, 4 hours, and 36 seconds.
[06:43:56] <MattyMatt> meh I got a used 160GB deathstar in the post this morning. I'll put that in a P3 800 with Lucid today
[06:46:48] <MattyMatt> I've changed my attitude to used hdd off ebay after asking the price of a new one in the local shop :p
[06:47:48] <Jymmm> where are you?
[06:47:54] <MattyMatt> UK
[06:47:58] <Jymmm> ah
[06:48:08] <MattyMatt> short boat ride from the old IBM factory in Dublin
[06:48:33] <Jymmm> s/IBM/Hitachi/
[06:48:45] <MattyMatt> they really were deathstars tho, the hitachi ones aren't so bad in my experience
[06:48:58] <Jymmm> I love mine
[06:50:51] <MattyMatt> they're all lovely until they die
[06:52:28] <MattyMatt> 64GB ssd or 1TB hdd same price. that was an easy choice
[06:52:38] <MattyMatt> 64GB is plenty :)
[06:52:50] <Jymmm> ha!
[06:53:34] <Jymmm> I have 8TB (raw) and only 40% available space!
[06:54:08] <MattyMatt> yeah but it's all pirated movies and music. no loss if that goes
[06:54:23] <MattyMatt> go on, admit it
[06:54:44] <Jymmm> No it's not, it's 25% pr0n!
[06:55:01] <MattyMatt> you buy your porn?
[06:55:10] <Jymmm> Buy? Make!
[06:55:26] <MattyMatt> those strumpets don't strump for free, ya know
[06:55:50] <MattyMatt> harlots don't harl
[06:56:33] <MattyMatt> unless you hide the camera of course
[06:58:34] <Jymmm> Machinest Pr0n.... "Swarf me baby, oh Yeah! You know how to ream me! go ahead baby, put your calipers on me, mic me baby, mic me!"
[06:59:37] <Jymmm> "Slap me on that big granite surface table of yours..."
[07:00:04] <MattyMatt> you forgot cranks, shafts and grease nipples
[07:00:26] <Jymmm> and jobber bits
[07:00:41] <MattyMatt> sliding fit
[07:01:03] <Jymmm> and can't forget the lube!
[07:01:29] <alex_joni> lube is for pussies
[07:01:36] <Jymmm> DUH!
[07:01:38] <Jymmm> =)
[07:02:34] <alex_joni> :P
[07:07:36] <Jymmm> I wish my Kill-A-Watt meter had a USB/Serial interface
[07:18:58] <mrsun> make your own ? :)
[07:19:22] <mrsun> uc + very tiny resistor to measure voltage drop ? :P
[07:19:27] <mrsun> or just a wire around the pin to measure how much current goes throught it :P
[07:22:09] <mrsun> http://jeelabs.org/wp-content/uploads/2011/09/direct-connect.png
[07:28:18] <Loetmichel_> mrsun: for ac some windings around the primary power live cable is the better way.
[07:28:39] <mrsun> Loetmichel_, was that i ment with the wire around the pin :P
[07:28:42] <Loetmichel_> Even isolated to the primary power
[07:28:56] <Loetmichel_> unlike your circuit ;-)
[07:28:59] <mrsun> that you just warp some cable around the live cable and get some induced voltage =)
[07:29:07] <mrsun> Loetmichel_, was an example circuit i found =)
[07:30:07] <Loetmichel_> 0.1 Ohm is a bit high, though
[07:31:15] <mrsun> as low as possible imo and then use an opamp to get the reading higher before adc =)
[07:31:19] <Loetmichel_> that would be around 1,6V for 16A and about 26Watts for the resistor. NOT a good idea if it cant cope with that ;-)
[07:32:32] <mrsun> http://circuits.linear.com/images/circuits/236_circuit_1.jpg thats more like it =)
[07:33:09] <mrsun> or http://www.maxim-ic.com/images/appnotes/746/746Fig10.gif
[07:33:52] <Loetmichel_> harhar, 0,1in copper....
[07:34:14] <Loetmichel_> reminds me of my flight charger battery pack....
[07:34:55] <Loetmichel_> http://www.cyrom.org/palbum/main.php?g2_itemId=9086 <- first try for a shunt resostor...
[07:35:08] <Loetmichel_> burned in no time.
[07:35:25] <Loetmichel_> http://www.cyrom.org/palbum/main.php?g2_itemId=9089 <- second try
[07:35:32] <Loetmichel_> http://www.cyrom.org/palbum/main.php?g2_itemId=9092
[07:35:43] <Loetmichel_> http://www.cyrom.org/palbum/main.php?g2_itemId=9095
[07:35:58] <Loetmichel_> ... has lived about 2 days ;-)
[07:36:10] <Loetmichel_> http://www.cyrom.org/palbum/main.php?g2_itemId=9098
[07:36:23] <mrsun> just use a massive copper bar? :)
[07:36:34] <mrsun> 0.35u x 0.1mm ... not alot =)
[07:36:37] <Loetmichel_> ... now there is a 20-pack of 0,33 Ohm 2W parallel ;-)
[07:40:17] <skunkworks> A2Sheds: yes - I have been using http://emergent.unpythonic.net/01198594294
[07:41:26] <skunkworks> For temp sensing of the spindle. http://www.electronicsam.com/images/KandT/testing/Screenshot-HEADCIR.25mill.ngc%20-%20AXIS%202.5.0~pre%20on%20HM2-Servo-1.png
[08:19:15] <Loetmichel_> reboot win7
[09:30:01] <mrsun> yey, it gives some result this scraping, down to 0.01mm diff over the table =)
[09:30:52] <mrsun> after this i think ill just call it quits with this machine .. and just assemble it and hope i can get 0.01mm accuracy and that will have to be good enough :P
[09:58:04] <tom3p> JT-Shop b4 i ferget "meat salt time' new book on diy air cured italian sausage ( and tom waits singin(?) 'chicago' on new album )
[10:36:49] <TRW_Aguascalient> Hi every body, i have a basic question about servo motors
[10:38:19] <TRW_Aguascalient> were can i find information about the difference between torque/current and velocity/speed mode, which one is better for a CNC application
[10:38:43] <JT-Shop> mmmm, italian sausage
[10:39:04] <JT-Shop> most applications that I know of use velocity drives for CNC
[10:46:26] <pcw_home> My take on this is that LinuxCNC can close the velocity loop with a torque mode drive but this requires a faster servo thread than normal
[10:46:28] <pcw_home> that is, LinuxCNC can make a velocity mode drive out of a torque mode drive. LinuxCNC and most LinuxCNC supported hardware has good
[10:46:30] <pcw_home> velocity estimation so can do just about as well as tachometer feedback velocity mode drives with a torque mode drive. The advantage of a torque mode drive
[10:46:32] <pcw_home> is that you know the force being applied to the load. This can be valuable for spindles and cases where you may want to limit torque (say during homing)
[11:04:51] <TRW_Aguascalient> thanks for the info, i will start with torque mode and if things go wrong i will switch
[11:19:10] <Jymmm> LC
[11:33:15] <Mjolinor> I have a bolt 5.8 mm OD, pitch 0.5 mm
[11:33:27] <Mjolinor> is it a standard size, I can't find any reference for it
[11:34:03] <Mjolinor> i asume it is nominal 6mm, possibly metric fine
[11:34:58] <Mjolinor> nope, not metric fine, any other suggestions?
[11:35:16] <jdhNC> does it fit an m6x.5 nut?
[11:35:24] <Mjolinor> I dotn have one :)
[11:35:50] <Mjolinor> I have never even seen one, tahts my problem maybe :)
[11:36:35] <Mjolinor> it is the thread on the thing I am using for my Z axisa on this small engraver thing I am making
[11:37:01] <Mjolinor> but it is only 23mm of movement, if I could find a bolt with the same thread I could increase my movement to 50 mm or so
[11:39:42] <archivist> make one
[11:40:14] <Jymmm> Mjolinor: Sounds like it's time to hit the hardware store for M1, M2, M3, M4,etc nuts to test it out =)
[11:40:30] <archivist> not a standard metric
[11:40:44] <Jymmm> ah
[11:40:52] <Jymmm> imperial?
[11:40:57] <archivist> no
[11:41:57] <Mjolinor> i think it is bespoke
[11:42:03] <Mjolinor> cant find any refernce to it anywhere
[11:42:32] <archivist> it is normal to make specials for certain work
[11:43:51] <Mjolinor> it must be very well made, I cleaned it wiht alcohol and still its easy to turn but no backlash in tit that I can detect
[11:45:59] <syyl> Mjolinor
[11:46:08] <syyl> thats a M6x0,5 fine thread
[11:46:33] <syyl> oh
[11:46:38] <Mjolinor> but its not standard is it?
[11:46:46] <Mjolinor> http://www.newmantools.com/tech/threadmf.htm
[11:46:48] <syyl> its a standard fine thread
[11:46:56] <Mjolinor> not listed there, 0.5 pitch stops at 5.5 mm
[11:47:11] <syyl> wait a second
[11:48:13] <syyl> refering to DIN m6x0,5 is a standard size
[11:48:47] <Mjolinor> so where would I go for a bolt?
[11:48:59] <syyl> to the next lathe
[11:49:04] <Mjolinor> :)
[11:49:10] <syyl> or a screw-shop ;)
[11:49:18] <syyl> finepitch screws are not that easy to get
[11:49:44] <Jymmm> http://MrMetric.com
[11:52:28] <Mjolinor> none there :(
[11:52:40] <Mjolinor> think I will make do with 23 mm movement :)
[11:52:49] <Jymmm> Yeah, I noticed. They dind't used to suck like that.
[11:53:07] <Jymmm> Looks like they got bought out
[11:54:17] <mrsun> use a lathe and make your own fine pitch screw? :)
[11:57:03] <syyl> i even have m6x0,5 tap/die in my box Oo
[11:59:56] <Mjolinor> http://rotagriponline.com/index.php?page=shop.product_details&product_id=1697&flypage=shop.flypage&pop=0&option=com_virtuemart&Itemid=29
[11:59:59] <Mjolinor> founbd one :)
[12:00:16] <Mjolinor> but it costs more than I paid for the whole assembly
[12:00:46] <syyl> try ebay
[12:01:30] <syyl> but for a leadscrew, i would go for a lathe..
[12:02:03] <Jymmm> could get a die
[13:30:04] <Ekkeri> http://rotagriponline.com/index.php?option=com_virtuemart&page=shop.browse&category_id=173&Itemid=29 damn, I want those :)
[13:46:32] <Ekkeri> PCW, any change to get that 7I52E firmware by end of next week?
[14:11:14] <A2Sheds> ok, now I need a low cost DIY rotary table to hold 4-8 vats of resin about the size of an 8" baking pan
[14:11:46] <Jymmm> steel lazy suzan
[14:12:25] <A2Sheds> 4 color process UV dlp printer
[14:12:46] <skunkworks> A2Sheds: did you get my note?
[14:12:50] <A2Sheds> glass table or t-slot
[14:13:05] <A2Sheds> skunkworks: yes, thank you!
[14:13:31] <skunkworks> works well - been using it for a month or more now with no issues/
[14:16:43] <mrsun> i wish i had a power scraper
[14:18:39] <A2Sheds> the 3d printers don't need realtime
[14:18:40] <Ekkeri> i wist i had a know how [Dto scrape :)
[14:18:46] <A2Sheds> so USB is fine
[14:19:32] <A2Sheds> and yes I could just wrote a bunch of Python to control the steppers over USB, but I'd rather do other things
[14:19:59] <A2Sheds> the reprap guys like to code
[14:20:15] <mrsun> thinking of getting it surface ground now, got the outsides of the table parallel to the sliding surfaces, so i could lay the table upside down, grind the parts that isnt flat there, turn it around and grind the table, and i would have 3 surfaces that is flat to eachother :P
[14:20:55] <Ekkeri> mrsun, where do you live btw?
[14:21:24] <Ekkeri> I'm 600m from Sweden :)
[14:21:41] <Ekkeri> almost there!
[14:36:25] <mrsun> haha yes, sweden
[14:36:52] <mrsun> Ekkeri, norweigian i presume? :P
[14:39:07] <Jymmm> mrsun: Nah, Ekkeri is Jamaican mon!
[14:39:58] <mrsun> ahh fi =)
[14:40:15] <mrsun> Jymmm, you are just full of phun today arent ya? :P
[14:40:27] <Jymmm> Ya mon!
[14:46:16] <Ekkeri> mrsun, which city/town?
[14:46:25] <mrsun> malung ... :P
[14:46:56] <Ekkeri> ok, never heard :)
[14:47:32] <mrsun> close to sälen
[14:47:37] <mrsun> that people usaly have heard of :P
[14:47:42] <Ekkeri> nope :)
[14:47:53] <Ekkeri> I'm next to Haparanda
[14:49:17] <Mjolinor> have you got northern lights tonight?
[14:49:30] <Ekkeri> too much clouds
[14:49:51] <Mjolinor> i want to see them
[14:50:38] <Ekkeri> I haven't even glanced outside, but I assume there are too much clouds :P
[14:51:09] <Mjolinor> they have been visible a long way south this week
[14:56:33] <Ekkeri> wow, I haven't any photos of those in the web
[14:57:43] <Jymmm> Is anyone interested in a ThinkJet printer?
[14:58:28] <jdhNC> not me, I got rid of mine years ago
[14:58:33] <Jymmm> k
[15:51:39] <Gromits> Anyone know offhand how to cause a message to appear in Axis (as various warnings do)? We have a custom M code and want to send a message to Axis rather than (in addition to, actually) std out.
[15:52:14] <cradek> you can do it with a gcode comment like this: (msg,This is the text)
[15:53:28] <Gromits> can we put that in the sh script for the M code?
[15:53:34] <cradek> no
[15:53:51] <cradek> for that perhaps check out the message hal component?
[15:54:04] <Gromits> ah, ok that is what we were looking for.
[15:54:09] <Gromits> thanks
[15:54:37] <skunkworks> Gromits: how is the journey?
[16:04:14] <andypugh> Gromits: Another way to print a message is from an M-code, have a look at http://www.linuxcnc.org/index.php/english/component/kunena/?func=view&catid=21&id=16859#16878 et. seq.
[16:05:32] <andypugh> Also suggestions for ways to have voice prompts (M-code, MP3 and command-line audio)
[16:06:14] <cradek> http://penny-arcade.com/comic/2012/01/25
[16:07:14] <cradek> oh I misunderstood :-)
[16:07:55] <andypugh> Talking cartoons, I had a real one of these today: http://www.xkcd.com/979/
[16:07:57] <cradek> hahahaha a png with the fixed message "Re-orientate [sic] part in vice [sic] !!"
[16:08:31] <cradek> I know it's a proof of concept, but still...!
[16:08:32] <andypugh> That's English.
[16:09:14] <cradek> it's the approach of displaying a png of text that makes it entertaining
[16:09:31] <andypugh> (Well, "Vice" is certainly correct for the poster, I am not sure about "orientate")
[16:09:38] <cradek> (msg,Text in whatever dialect you want here)
[16:09:52] <cradek> !!
[16:09:57] <andypugh> He wanted something visible across the room.
[16:10:41] <cradek> ok....
[16:11:00] <cradek> you still can't convince me it's not funny :-)
[16:11:33] <Gromits> Ok, the message component worked. Thanks! No need to display porn or female voices (yet :-)
[16:12:13] <Gromits> skunkworks: we have the machine working great....except the torch failed. I am taking it in tomorrow to be repaired :-(
[16:12:15] <cradek> I have always been able to notice when the machine has stopped and is waiting for me to do something, regardless of the size of text on the screen, but perhaps the situation is different in this case.
[16:12:20] <cradek> Gromits: yay!
[16:12:45] <andypugh> Well, am EPS would have been more efficient, and could be created on-on-the-fly...
[16:13:05] <cradek> or it could have two large flags and use semaphore
[16:13:51] <dvmirc> PNGs can be created on the fly as well :-)
[16:14:00] <andypugh> I wrote a Semaphore Tutor for the Psion Organiser. I used the Venus-de-Milo as the interlocutor.
[16:19:11] <Gromits> skunkworks (et al): http://www.youtube.com/watch?v=2ahvyyJxfuw&list=UUh7EMlVMJoE7-hPevtViOoQ&index=1&feature=plcp
[16:19:25] <cradek> andypugh: awesome
[16:20:01] <skunkworks> Gromits: cool - already saw that - didn
[16:20:06] <skunkworks> 't know it was you
[16:20:09] <mrsun> its a plasma that cuts plasma ?
[16:20:16] <Gromits> of course
[16:21:30] <andypugh> I haven't seen an underwater one before.
[16:21:55] <andypugh> Probably better than gasoline.
[16:22:00] <Gromits> well it shouldn't be fully submerged but a small amount isn't a big deal
[16:22:19] <Gromits> I did actually raise the slats today so they are about .125 above the water
[16:22:41] <Gromits> There are torches made to cut fully submerged, the Powermax 45 isn't one of them...
[16:23:35] <Gromits> I am so bummed the torch is broken. I feel like a kid on Christmas with no batteries :-(
[16:24:20] <skunkworks> Gromits: what did you end up with for drive and stuff?
[16:25:13] <Gromits> Granite Devices VSD on X and Y1, Y2 and a Gecko 320X on Z
[16:25:59] <Gromits> We have a 10:1 gearbox on the X axis now and it runs beautifully. So we orderd two more gearboxes for the Y axis.
[16:26:19] <skunkworks> step/dir or ...?
[16:26:22] <Gromits> We have learned lots about servos and gearing
[16:26:27] <skunkworks> heh
[16:26:37] <Gromits> Yes, step/dir on the Granites and Gecko
[16:37:31] <Gromits> Ever hear for 3M VHB?
[16:37:36] <Gromits> for==of
[16:38:11] <Gromits> VHB is Very Heavy Bond - tape
[16:39:39] <Gromits> Our water pan isn't welded, it is taped together! The water pan is 1/16" aluminum plate taped to 1/8" alum L-channel. Silicone, and done.
[16:42:03] <andypugh> There are tapes suggested as alternatives to spot-welding
[17:36:33] <Jymmm> 3M Makes a WHOLE LOT of funky sticky stuff
[17:37:17] <Valen> even some non sticky stuff
[18:14:21] <Jymmm> Is DUAL CPU fully supported in LinuxCNC yet?
[18:14:43] <cradek> what do you mean by fully supported
[18:15:06] <cradek> and what do you mean by LinuxCNC - do you mean the kernel on our cd?
[18:15:10] <Jymmm> cradek: Like out of the box and can take advantage of the dual cpus?
[18:15:49] <cradek> guessing you mean our livecd. yes it is an smp kernel that uses both cpus.
[18:16:16] <Jymmm> cradek: (I'm not trying to be funny, just seeing if this mobo/cpu I have is worth it) http://www.supermicro.com/Aplus/motherboard/Opteron/nForce/H8DCE.cfm
[18:16:17] <cradek> you can also optionally reserve/isolate one cpu for exclusive use by the realtime tasks
[18:16:49] <Jymmm> cradek: It's two dual-core cpus actually, I don't know if that makes a difference.
[18:17:06] <cradek> dunno about nvidia chipset. if you're stuck using their video drivers, that can be problematic.
[18:18:03] <Jymmm> It's a server mobo, so not really expecting much performance video wise.
[18:18:36] <cradek> that's not the point really, if you're wanting realtime performance
[18:18:43] <cradek> the nvidia binary drivers screw that up
[18:18:50] <Jymmm> Ah, ok.
[18:19:00] <cradek> but I don't know if you'd need to use them.
[18:19:12] <Jymmm> I wasn't sure if the nvidia issues were related to the high end nvidia chipsets or not.
[18:19:28] <Jymmm> s/related/isolated/
[18:19:58] <cradek> it's specifically their driver, I think
[18:20:10] <cradek> if you can use nv, noveau, or vesa, you're generally fine
[18:20:29] <Jymmm> Yeah, I think vesa is fine.
[18:21:08] <Jymmm> Man it seems such a waste of a mobo like this.
[18:21:49] <Jymmm> 8 sata ports, great for a NAS box, but who wants a two cpu box idling around 24/7/365
[18:22:33] <Jymmm> cradek: Hey, hows the tape drive treating you?
[18:22:39] <cradek> it works great
[18:22:52] <cradek> backs up all my stuff and all of linuxcnc's stuff
[18:23:09] <cradek> also, sounds like a jet
[18:23:20] <Jymmm> cradek: Good to hear it, glad it wasn't a dud after all that freight and such.
[18:23:36] <cradek> yeah, shipping was a pain, but worth it
[18:23:58] <Jymmm> cradek: Did all three drives work?
[18:24:25] <Jymmm> I wasn't sure about one of them.
[18:25:55] <cradek> I'm not sure I've ever done more than load and eject with all 3
[18:26:02] <cradek> I just use 1
[18:26:39] <Jymmm> Ah, heh.
[18:27:51] <Jymmm> I neither have nor want a clue about it - evil tape drives, YUCK! Just glad it's thousands of miles away from me ;)
[18:29:16] <Jymmm> cradek: Ok, do you think that mobo is worth running LCNC on?
[18:29:50] <cradek> are you trying to do something special or just run an everyday machine?
[18:30:07] <cradek> I'd probably never go looking to buy new hardware for use as a linuxcnc control
[18:30:08] <Jymmm> cradek: everyday stepper
[18:30:19] <cradek> meh just use whatever you've got in the basement then
[18:30:42] <cradek> I just updated mine from a p3-1000 to a p4-1xxx, both are perfectly adequate
[18:31:33] <andypugh> Bother! version 2 of my little PCB is wrong too, wrong pinout on the Hall sensors! This is getting annoying.
[18:31:43] <Jymmm> cradek: That's pert of the issue, I have too much HW here and trying to thin it all out. I have 3 or 4 1U servers, plus other mobo/cpu's etc and trying to figure out what to keep and what to toss.
[18:31:43] <cradek> arg!
[18:32:13] <andypugh> I have no-one to blame but myself, sadly.
[18:32:17] <Jymmm> Though 1U's are LOUDER THAN HELL ON RACE DAY!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
[18:33:18] <Jymmm> drag strip race day that is =)
[18:33:34] <andypugh> However I will probably use this as an excuse to design the Mk2 PCB to suit a much neater design.
[18:33:56] <PCW> fixable with X-acto /30 gauge wire editing?
[18:34:07] <andypugh> After all, nobody ever wants to finish a project if you can come up with a better idea :-)
[18:34:29] <andypugh> PCW yes, maybe even just with solder bridges.
[18:35:16] <andypugh> But I am slightly bugged by a couple of other issues too.
[18:35:41] <PCW> not a total loss, look on the bright side if you patch it you may find more errors to fix on Mk2
[18:36:09] <Jymmm> andypugh: sell them as patched cheap knockoffs =)
[18:36:43] <andypugh> I wonder if I can find sensors with the right pinout?
[18:37:39] <PCW> sometimes reverse bending the leads helps
[18:38:18] <PCW> (assuming they have leads)
[18:38:31] <andypugh> Not here, I have 0.2mm clearances between the sensors and moving parts.
[18:39:50] <andypugh> Why do they put the pin numbers on page 7 and functions on page 2?
[18:42:41] <PCW> Xilinx supplies pinouts as spreadsheets which are a nice starting point nice to massage into schematic library objects
[18:43:55] <PCW> I always get someone else to check my work, even then we screw up PCBs with fair regularity
[18:47:03] <PCW> probably getting too old for this...
[18:58:48] <MattyMatt> Jymmm I changed the cpu fan on this machine, wish I had 5 years ago
[18:59:36] <MattyMatt> maybe they used noisy ones on purpose, to make a statement
[19:00:22] <MattyMatt> best £2 I've spent in ages
[19:01:56] <MattyMatt> don't forget Sod's Law. the thing you tossed yesterday is the thing you need today :) hoard it all
[19:02:11] <MattyMatt> do the 1U have wake on lan?
[19:06:45] <MattyMatt> microservers are catching on. I'd rather have 4 (quiet) 1U than VM's for a web server
[19:07:55] <Jymmm> There is no such thing as a QUIET 1U =)
[19:08:28] <alex4nder-> tag
[19:08:36] <alex4nder-> er yah,.. my 1Us all sound like they're going to take off.
[19:09:06] <Jymmm> one of mine has *SIX* 15,000 RPM fans in it... hostname == BANCHEE
[19:19:13] <andypugh> Well, I have managed to mod one board, so it looks like I an get it working this week. I need more components though.
[19:30:47] <skunkworks> andypugh: yay
[19:31:31] <andypugh> Well, I have mixed feelings, I had thought of a much neater way to do stuff, and I only have to change 3 of the main mechanical components...
[19:35:16] <Jymmm> andypugh: How many boards did you get/order?
[19:35:43] <andypugh> 10
[19:36:04] <Jymmm> Oh, well thats not TOO many at least. Lot better than 20 or 50
[19:36:20] <andypugh> $14 all-in so I only care about the wasted time, not the money
[19:36:31] <Jymmm> andypugh: Oh, heh.
[23:21:54] <Tecan> is there a torrent ?
