[00:44:32] <Goslowjimbo> pcw: In looking a using a 7i43 to talk SPI to a 7i37, will I need to alternate between writes for the SPI and servos, or will 1 write suffice for both simultaneously?
[00:46:00] <Goslowjimbo> Said another way, does the write_address pin in raw mode get used normally by the EMC system?
[01:32:36] <SWPadnos> Goslowjimbo, raw mode is normally not used, so I'm sure the addresses and read/write pins are unused
[01:33:02] <pcw> Goslowjimbo Not sure but I doubt it.
[01:33:13] <SWPadnos> I'm pretty sure the write function will write all the GPIOs, the servo settings, and optionally read and write SPI if raw mode is enabled
[01:36:56] <Goslowjimbo> I'll go with that, then, until it proves otherwise.

[02:26:19] <tomp> tomp is now known as tom3p
[02:28:00] <tom3p>  jepler: did you add a 3rd channel (index) to those pitmann motors? i found the 3 channel is expensive.. best price is jameco at 34.95 for 3 channel heds-5540 ( mouser allied avago digikey all much higher )
[02:29:05] <SWPadnos> for small motors: http://search.digikey.com/scripts/DkSearch/dksus.dll?Detail&name=102-1308-ND
[02:29:24] <jepler> tom3p: no, making do without index. homing to switch-only was good enough for me on steppers, hoping it will be for servos as well
[02:29:31] <SWPadnos> (small shafts, actually)
[02:32:20] <Jymmm> that's what she said.
[02:33:03] <tom3p> SWPadnos: thx for that link i had not heard of CUI, and the shaft collars is a nice idea.
[02:33:44] <SWPadnos> Mariss swears by those encoders. apparently he's been using them in development of the step-servo drive and the G380x
[02:33:49] <tom3p> jepler: thx, i may try to make a plate for a single index photo interrupter ( got lotsa shaft, (yes yes thats what she said ))
[02:34:30] <Jymmm> tom3p: SHAE's giving YOU lots of shaft?! Kinky
[02:34:39] <Jymmm> s/SHAE's/SHE's/
[02:38:00] <toastydeath> epic.
[02:48:13] <tom3p> is this true? if i use the 7i30 quad 100W driver, and the m5i30, it's pwm compatible, no integration needed to convert PWM to real analog
[02:50:47] <tom3p> hmmm. does mesa still publish prices? used to be a special page, a text list.
[02:52:22] <tom3p> ahah, you have to goto some sub page, then to home, else the link to prices doesnt appear ( ffox 3.01 rendering anyway )
[02:52:49] <SWPadnos> the main page has a frame which has the link to the price list
[02:53:05] <SWPadnos> if you load a product line page outside the frameset, you don't get those links
[02:54:33] <tom3p> nope, still no link to prices... set url to "http://www.mesanet.com/" isnt that the main page? (or hand me a link please )
[02:55:30] <SWPadnos> Price List, second from the bottom on the left side (not coundint the "get acrobat" icon)
[02:55:37] <SWPadnos> counting
[02:55:42] <SWPadnos> http://www.mesanet.com/prices.html
[02:56:23] <tom3p> found it... the scroll bar doesnt scroll to bottom, but arrow cursor does DOH!
[02:56:42] <SWPadnos> oh. short monitor syndrome ;)
[02:56:43] <tom3p> and thx
[02:56:47] <SWPadnos> sure
[02:56:58] <SWPadnos> tab should also cycle to it eventually
[02:57:18] <tom3p> sure, there's water in the pool, just jump in
[02:57:35] <SWPadnos> while carrying high power electronics :)
[03:02:03] <tom3p> does the 7i30 sound like a good solution for 4 axis of those 24V Pittman motors Jepler got? the closest data sheet i found said 0.16A no load & 9.64A stall... way past 100W@)
[03:02:27] <tom3p> i hope to not run them at stall ;)
[03:15:13] <skunkworks> jepler: Very cool pictures.
[03:38:09] <jimbo655> Joint follow error... Is there a tool for trouble shooting that gives more info.
[03:41:54] <jimbo655> After I hooked up the linear encoder when I try to power up this message comes up instantly.
[03:51:21] <cradek> scope commanded and feedback position at power-up
[03:52:01] <cradek> they are diverging for some reason
[03:52:14] <cradek> that's what a following error means
[04:14:36] <jimbo655> This makes no sense I do not know where this numnber comes from. F(-2.34665) = 0.16216
[04:15:18] <jimbo655> How do I turn off the index inputs?
[04:16:09] <jimbo655> on the m5i20
[04:44:17] <pcw> index-enable?
[04:50:41] <jimbo655> On the hal scope I see commanded as a flat line with feedback being a rising line until turnoff
[05:49:03] <Valen> so I have the EMC system in place
[05:49:19] <Valen> being a very under featured DRO at the moment ;->
[05:54:13] <Valen> and the 2500 latency is helping lots lol

[07:46:57] <hesperaux> does anyone here use a homemade rig?
[07:47:31] <archivist> yes a few
[08:22:26] <pjm> morning
[08:23:46] <archivist> good moaning
[09:23:37] <piasdom> g'mornin all
[09:26:17] <micges> good morning
[10:08:08] <EliasCNC> hi. I'm new with emc and I have a slight problem right away. I got the port etc motor settings fine and all (XYZ) move fine but x and y are inverted
[10:08:19] <EliasCNC> once I have set the pins to invert I can not home anymore
[10:08:24] <EliasCNC> no limit switches are used
[10:09:12] <EliasCNC> emc does not move the axis to the negative side anymore after inverting and home is pressed but it only zeros the axis and leaves some icon next to the axis
[10:09:33] <EliasCNC> before the pins are inverted homing also works fine
[10:30:06] <pjm> EliasCNC u could try to swap over the a/b phases of the motors so u dont have to invert the direction
[10:31:11] <EliasCNC> that is one solution of course I was just wondering if this is some setting that is causing this or something else software related that is easy to change
[10:46:28] <alex_joni> EliasCNC: the other way to invert an axis is to put a negative sign on the SCALE
[10:46:47] <alex_joni> but most likely you unhooked the homing switch on the pinout page when rerunning stepconf
[11:03:29] <EliasCNC> ok I will have to see later. will get back here later if we can't figure it out. thanks for the info
[11:24:00] <alex_joni> EliasCNC: sure
[12:05:43] <jepler> if you need homing to move in the opposite direction, negate the homing velocity on the axis setup page.
[12:06:13] <jepler> yes, if you put e.g., "min + home x" it would be ideal if stepconf figured out which way to move the axis to begin homing, but it doesn't.
[14:38:44] <skunkworks> jepler: don't know if you read back - but awesome picuters!
[14:39:08] <jepler> skunkworks: thanks
[14:39:51] <jepler> I like the little frog best
[14:44:31] <skunkworks> I like the fatty carpenter bee ;)
[14:57:36] <geo01005> Parametric Sketches in HeeksCAD: http://www.youtube.com/watch?v=nibjuxCbUag
[14:57:48] <geo01005> Finally got parts of it working well.
[14:59:17] <geo01005> looking for more developers, anybody interested?
[15:12:35] <skunkworks> geo01005: that looks cool!
[15:14:30] <geo01005> I know ;)
[15:16:46] <geo01005> I hope to find some developers that work, or have worked on some of the commercial CAD packages.
[15:17:23] <geo01005> But any additional developers are good.
[15:29:12] <micges> logger_emc: bookmark
[15:29:12] <micges> Just this once .. here's the log: http://www.linuxcnc.org/irc/irc.freenode.net:6667/emc/2009-06-29.txt
[17:17:44] <roel01> all>Hi
[17:18:11] <micges> hi
[17:52:10] <Jymmm> Had an external hdd get hot yesterday, even the plastic case was too hot to touch. I also have 2 1U servers that each have 4 15K RPM fans that scream. Want to toss all of it in a portable 14U enclosed rack that has the front, back, and bottom open. Need to figure out some fan/blower thing that has lots of volume, but not too loud. Any ideas? (would disconnect the internal fans on the 1U servers)
[17:54:22] <archivist_attic> its not box volume that matters but volume of air passing the hot bits per minute
[17:55:20] <Spida> Jymmm: disconnecting the fans on 1U servers is a BAD idea. how do you want to cool them?
[17:55:57] <Jymmm> redirect from rear to front
[17:56:10] <Jymmm> which is basically what they do now
[17:56:36] <Spida> Jymmm: how, without fans?
[17:57:02] <Jymmm> use a blower
[17:57:15] <SWPadnos> with a big fan ont he rack case, instead of little fans in the 1U cases
[17:57:17] <SWPadnos> on the
[17:57:33] <Jymmm> multipe fans on the rack
[17:57:38] <Jymmm> in case of failure
[17:57:48] <Spida> that would cool the CASE of the 1U server, but not the components INSIDE....
[17:57:53] <SWPadnos> for lower noise, you want to use the largest and slowest fans possible
[17:58:08] <Jymmm> Spida: It would be vented THRU the 1U
[17:58:15] <SWPadnos> yes, to a certain extent that's true
[17:58:26] <Jymmm> Spida: Take a pipe and blow in one end
[17:58:51] <Spida> you didn't mention a pipe or any air-ducting before...
[17:59:03] <Jymmm> SWPadnos: Yeah, need to have a large enough volume to prodcue back pressure to know
[17:59:12] <Jymmm> Spida: nm
[18:01:24] <Jymmm> SWPadnos: Fans are easy to get, but many large ones don't have a rpm lead
[18:02:10] <SWPadnos> you could use a window fan or two
[18:02:23] <SWPadnos> but they definitely won't have the tach lean
[18:02:25] <SWPadnos> lead
[18:02:55] <Jymmm> let me measure the rack for cubic feet real quick
[18:05:23] <SWPadnos> it should be about a 2 foot cube inside (+/- an inch or two)
[18:05:33] <SWPadnos> so close enough to 8 cubic feet
[18:05:54] <Jymmm> 24
[18:06:05] <SWPadnos> what?
[18:06:14] <SWPadnos> is it 36" deep?
[18:06:21] <Jymmm> 24" x 24" x 36"
[18:06:27] <Jymmm> yep
[18:06:28] <SWPadnos> that's 12
[18:06:33] <SWPadnos> 2*2*3 = 12
[18:06:55] <Jymmm> ok 12
[18:07:07] <SWPadnos> you didn't check that with a calculator, did you?
[18:07:09] <SWPadnos> :)
[18:07:28] <Jymmm> I'm still on first cup of coffee
[18:07:39] <SWPadnos> oh, right
[18:14:20] <Jymmm> Max airflow: 1.45 m^3/min
[18:14:43] <Jymmm> Max static pressure: 20 mmH20
[18:15:41] <Jymmm> 12 (cubic feet) = 0.339802159 cubic meters
[18:16:22] <Jymmm> SWPadnos: Know anything about static pressure? I'm clueless on the values/units
[18:17:09] <SWPadnos> 1 atmosphere is 760 mm Hg
[18:17:23] <SWPadnos> other than that, I'm clueless also
[18:17:34] <Jymmm> awesome! wth does that mean =)
[18:17:37] <Jymmm> lol
[18:17:53] <archivist_attic> 14.7 psi ish
[18:18:11] <SWPadnos> so the max static pressure of that fan is 0.026 atmospheres
[18:18:13] <archivist_attic> 1000 mb
[18:18:38] <SWPadnos> or about 0.38 psi
[18:18:43] <SWPadnos> ie, not much push there
[18:19:24] <SWPadnos> if you have a lot of obstructions, or there are other things that would limit airflow (such as a filter or grille), then the actual airflow will be lower than the 1.4m^3 quoted
[18:19:30] <Jymmm> ok, so basically anything would stop the blower
[18:19:41] <SWPadnos> it won't stop the blower, it'll reduce the airflow
[18:20:03] <Jymmm> I wonder if I can just install a $5 hooker or two instead???
[18:20:18] <SWPadnos> if you can find one (or two)
[18:21:04] <Jymmm> think the servers might get a virus?
[18:21:20] <SWPadnos> you'd have to experiment
[18:21:27] <Jymmm> uh, no thanks
[18:24:28] <Jymmm> SWPadnos: Hey! I can use ONE 80mm fan... 100CFM
[18:24:47] <SWPadnos> WHAAAAAAT?
[18:25:06] <SWPadnos> COULD YOU TURN OFF THE COMPUTER, I CAN'T HEAR YOU
[18:25:47] <Jymmm> 46dBA
[18:26:11] <Jymmm> 0.281 static pressure inH2O
[18:27:16] <Jymmm> SWPadnos: It's the static pressure I don't have a clue what I would need
[18:27:26] <SWPadnos> me either
[18:27:40] <Jymmm> and fans do better pushing than they do pulling
[18:27:55] <SWPadnos> I don't think that's true, but it could be
[18:28:17] <SWPadnos> they're always doing both, we humans just don't feel it as well when we're on the intake side
[18:28:21] <Jymmm> I tested it a ways back, could be different now, but no clue
[18:28:44] <SWPadnos> I think it depends more on the shape of the intake / outflow manifolds
[18:31:02] <Jymmm> SWPadnos: Here we go... http://www.excesssolutions.com/cgi-bin/item/ES4605
[18:38:21] <Jymmm> SWPadnos: http://www.excesssolutions.com/cgi-bin/item/ES4697 and it's datasheet http://www.nidec.com/fanpdfs/ta300dc.pdf
[18:48:13] <Jymmm> SWPadnos: I broke my first rule <rolls eyes>. KISS... 20" box fan from hardware store... $10
[18:48:54] <Jymmm> not too loud, has some volume, not sure on the pressure
[18:49:14] <SWPadnos> that's what I was saying
[18:49:16] <SWPadnos> window fan
[18:49:33] <SWPadnos> you probably didn't notice because I almost never suggest cheap stuff :)
[18:50:22] <Jymmm> when I hear "window fan" I think these: http://images.bountii.com/thumbnails/a8/15/a81566edfaed472be64e9cc1859a98ee
[18:50:34] <SWPadnos> yep, that's one type
[18:50:46] <SWPadnos> I also think of the box fans as window fans
[18:50:53] <SWPadnos> since that's how we used to use them
[18:51:03] <Jymmm> http://www.air-n-water.com/photos/2152-b.jpg
[18:51:09] <Jymmm> Now, THAT's a box fan
[18:51:19] <SWPadnos> yep
[18:51:23] <SWPadnos> just like mom used to buy
[18:51:24] <Jymmm> it even looks like a box... get it? got it! good!
[18:52:35] <Jymmm> this is a GREAT idea... http://www.americanallergysupply.com/dylos/index.htm
[18:52:54] <Jymmm> scroll down a bit
[18:53:54] <Jymmm> can keep the dust and junk filtered out
[18:54:41] <SWPadnos> hmmm. interesting
[18:54:49] <SWPadnos> I should ty that, my wife is allergic to dust
[18:55:23] <Jymmm> and filters are cheap
[18:56:00] <SWPadnos> but, but, but. they don't say if they're blowing into or out of the filter!!!
[18:56:13] <SWPadnos> how will I know if it's working without buying their $189 meter?
[18:56:14] <Jymmm> SWPadnos: Use bungy cords to attache the filter to the fan
[18:56:28] <SWPadnos> oh please. have some class
[18:56:30] <SWPadnos> use duct tape
[18:56:57] <Jymmm> SWPadnos: Measure the color of your wifes nose.... If a crimsome rose color vs blood orange, it's working
[18:57:16] <Jymmm> the nose knows
[19:03:50] <Jymmm> * Jymmm grabs the box fan and dry fits it in the rack...
[19:22:20] <Jymmm> OH THIS IS JUST TOO COOL.... Even though the bottom of the rack is open, there's about 7U uncovered in the front, and I put a 20" fan into a 24" opening, I can still feel airflow thru the (off) 4U server
[19:29:36] <Jymmm> I figure if I cover the bottom (already have the sheet material), and cover up the open slots in the front, I could actually get some desent air flow - hopefully enough though
[19:41:36] <Jymmm> SWPadnos: One week old filter on the right, new filter on the left: http://www.americanallergysupply.com/images/remodeling.jpg
[19:44:04] <SWPadnos> icky
[19:47:43] <archivist_attic> about 5 minutes near the buff at work
[19:55:53] <Jymmm> Nice fans... Lakewood has filed for Chapter 7 liquidation. We are no longer honoring warranties or repairing units. Please do not send them in for warranty or repair work.
[19:56:00] <Jymmm> sucks to see things like that.
[19:56:14] <Jymmm> had a removeable cord too
[20:01:21] <Jymmm> Hmmm, how to install or use a tach on a box fan ????
[20:36:53] <SWPadnos> cool. 8/1 Mbit DSL is only $60 here now. woohoo!
[20:37:40] <archivist> a month, a year?
[20:37:49] <SWPadnos> a month, sadly
[20:38:10] <SWPadnos> but it's pretty good considering that 5/1 is $50, and 2/0.5 is $30
[20:38:45] <motioncontrol> good evening.i ahave read tutorial with craete a userspace componebt.i want open the window with text for maschine allarm .please have a example the python file the userspace component with additional code for open the windows message when the hout = 1 value.thanks?
[20:38:46] <SWPadnos> oh, and it includes a fixed IP, and it's a business-class offering
[20:39:18] <jepler> motioncontrol: axis_manualtoolchange is an example of a python userspace component that does something (shows a GUI window) based on the value of a HAL pin
[20:39:20] <SWPadnos> motioncontrol, are you looking for a window to pop up when a HAL pin changes?
[20:39:33] <archivist> we have 8 meg here and fixed ip but... up is not so good
[20:39:44] <motioncontrol> yes
[20:39:51] <SWPadnos> if I lived closer to town, I could get 16/2
[20:40:00] <motioncontrol> have please a pretical example?
[20:40:12] <SWPadnos> hal_manualtoolchange is a practical example
[20:40:21] <SWPadnos> err, axis_manualtoolchange
[20:40:47] <motioncontrol> ok, i study it
[20:40:59] <motioncontrol> thanks for help
[20:44:23] <motioncontrol> excuse what is locate the axis_manualtoolchange . i have see only hal_manualtoolchange
[20:45:11] <SWPadnos> then it's hal_manualtoolchange :)
[20:45:49] <motioncontrol> ok thanks
[20:46:24] <SWPadnos> this is another example jepler made: http://media.unpythonic.net/emergent-files/sandbox/error.comp
[20:47:10] <jepler> that's not a Python component, though.
[20:47:16] <SWPadnos> true
[20:47:38] <jepler> it relies on the fact that rtapi messages printed with level ERR are converted into operator messages by the emc motion controller
[20:47:57] <jepler> (this is true for emc but not if you're using a hal-only application)
[20:49:12] <motioncontrol> ok, but open the new windows with text ?
[20:49:29] <motioncontrol> or write in terminal?
[20:49:52] <SWPadnos> display of the error message is up to the GUI, not the example I linked to
[20:50:27] <SWPadnos> as jepler pointed out, it relies on the motion controller to turn RTAPI errors into operator messages
[20:51:02] <jepler> .. and then on whatever your user interface does with operator messages. for instance, in 2.3, tkemc displays a pop-up with an OK button, while AXIS overlays the message in the lower right corner
[20:51:16] <jepler> and halui has no provision for operator messages
[20:51:53] <motioncontrol> ok i prove at use this component
[20:58:42] <motioncontrol> excuse jepler i have rename your code in a editoe file messaggi.comp and i have copy in hal/component.in src i have start make , but have the error license notspecified. because?
[21:00:10] <jepler> because that code is old and hasn't been updated for emc 2.3. http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?UPDATING#comp_file_changes
[21:01:50] <motioncontrol> ok compile
[21:02:02] <motioncontrol> success compile
[21:04:24] <motioncontrol> excuse i don't , have a error : fuction ?get_current? is inizialized like aa variable ?
[21:04:51] <motioncontrol> excuse i rewrite english
[21:06:28] <motioncontrol> i have a error in compile : messaggi.comp:10: error: fuction 'get_current' is inizialized like a variable. because?
[21:08:06] <jepler> probably something you wrote is wrong.
[21:08:19] <jepler> get_current happens to be the name of a function already defined by the linux kernel
[21:08:24] <jepler> it may have to do with that, or it may not
[21:08:34] <jepler> since you have the source code and I don't, I am only capable of guessing.
[21:08:40] <motioncontrol> jepler i have copy your code
[21:09:33] <motioncontrol> i ave additional only license "GPL";
[21:09:42] <jepler> and renamed it so I would have no idea that you were referring to my code
[21:10:35] <motioncontrol> i rename current in data message for example?
[21:10:52] <jepler> yes, it appears that current is also a name used by the linux kernel
[21:11:01] <jepler> I probably tested that component only on sim; it is of no practical use to me
[21:11:04] <motioncontrol> ok i prove
[21:11:58] <motioncontrol> ok compile with success
[21:12:21] <motioncontrol> i rename current in messagein
[21:12:52] <jepler> bbl
[21:14:03] <motioncontrol> i have use more component with : loadrt messaggi count=20 ?
[21:14:43] <motioncontrol> and addf messaggi.0 servo-thread?
[21:15:09] <motioncontrol> and messaggi.1 , messaggi.2 eccc, for more message list
[21:15:13] <motioncontrol> ?
[21:25:33] <SWPadnos> motioncontrol, yes, that's how you add the message functions to threads
[21:26:07] <SWPadnos> I'm not sure how you'll set the different message text though, unless all you want is to print "ERROR 12" or similar
[21:27:28] <motioncontrol> i have a problem emc not start have error :insmod: error inserting '/usr/realtime-2.6.24-16-rtai/modules/rtai_hal.ko': -1 File exists
[21:27:28] <motioncontrol> Realtime system did not load
[21:27:28] <motioncontrol> Shutting down and cleaning up EMC2.
[21:28:20] <geo01005> I'm starting to regret buying this goal3+ motherboard.
[21:28:37] <geo01005> No power up after power loss option in the bios.
[21:29:04] <SWPadnos> isn't there an "always on" option?
[21:29:19] <geo01005> can't find one.
[21:29:22] <SWPadnos> hmm
[21:30:07] <motioncontrol> i don't understand i compile with success.i have execute make clean, after make and sudo make setuid, but have error because?
[21:30:16] <geo01005> it is a very cheap motherboard.
[21:31:19] <motioncontrol> i restart pc a moment
[21:31:56] <SWPadnos> hmm. yeah, I don't see it either
[21:31:58] <SWPadnos> oh well
[21:32:29] <geo01005> I need it to turn on automatically in the machine I'm making.
[21:32:56] <geo01005> considering some kind of one shot signal on the soft power button.
[21:33:00] <SWPadnos> you can make that happen by shorting a couple of pins on the ATX power supply
[21:33:12] <SWPadnos> I don't recall which ones
[21:33:23] <geo01005> yeah, I did that, the power supply turns on, but the board dosen't boot.
[21:33:28] <geo01005> http://www.expresshosting.net/howto/atx-powersupply-modification-auto-turnon.html
[21:33:32] <SWPadnos> hmm
[21:33:48] <alex_joni> good night all
[21:33:56] <geo01005> night, alex.
[21:33:59] <SWPadnos> see you alex_joni
[21:35:42] <geo01005> what is the usual color of the 3.3v line?
[21:35:57] <SWPadnos> orange maybe?
[21:36:33] <geo01005> I'm thinking if I jumper from the soft switch button to the 3.3v line it will pull it low till the supply starts then leave it at the normal 3.3v level while running.
[21:37:21] <SWPadnos> I don't know if that's a 5V or a 3.3V input
[21:37:44] <geo01005> I just measured it, 3.3v
[21:37:53] <geo01005> do you think that would work?
[21:37:54] <SWPadnos> you could also try sticking a jumper on the power switch pins :)
[21:37:59] <SWPadnos> see what happens
[21:38:04] <SWPadnos> I wouldn'ty l
[21:38:06] <SWPadnos> gah
[21:38:19] <SWPadnos> I wouldn't directly connect a power supply pin to a logic input as my first choice
[21:38:50] <SWPadnos> hmmm. bbiab
[21:39:27] <geo01005> When i short the power pins it starts then stops because some kind of watch dog timer always bites when they are shorted for more than about 5 seconds.
[21:46:08] <motioncontrol> good evening .Jepler i have restart pc and emc load with success.when i loadrt megssaggi in hal file the terminal have error : module 'messaggi' not loaded. because

[22:15:28] <ds3> @$!$#$%@@$@#$@#$ abs chips are almost as bad as aluminum chips
[22:34:56] <kakeman> can you recommend this? http://www.pminmo.com/3axisPIC/3axisPIC.htm ?
[22:39:17] <cradek> nope
[22:42:39] <kakeman> why not?
[22:45:15] <cradek> stepper drives that aren't choppers are a waste of time, effort, and money - because you will go on to buy a chopper drive, I can almost guarantee.
[22:46:16] <cradek> bbl
[22:46:34] <kakeman> but there is seperate chopper?
[22:49:44] <kakeman> is that chopper current limiting circuit?
[23:16:28] <Jymmm> SWPadnos: Hey, if you try that fan filter thing for the wifey's allergies, when it gets dirty and needs to be replaced, just turn it around and you'll be good to go for another couple of weeks!
[23:18:24] <SWPadnos> um. NOT!
[23:18:48] <Jymmm> SWPadnos: LOL
[23:19:12] <Jymmm> SWPadnos: 20" Box fan I bought says it's 3883 CFM
[23:19:26] <SWPadnos> I probably will pop down to Lowe's tonight to try it
[23:19:38] <SWPadnos> yesh, there's no substitute for size ;)
[23:20:05] <Jymmm> SWPadnos: Dont foget the nice clean bungy cords so she doesn't go EWWWWWWWW
[23:20:49] <Jymmm> SWPadnos: Also, check to make sure the power cord doesn't come out in the middle of the fan
[23:21:26] <Jymmm> SWPadnos: My other one does, but that one the cord is removable.
[23:21:54] <SWPadnos> middle as in where the motor is?
[23:21:59] <SWPadnos> or middle of the bottom?
[23:22:14] <SWPadnos> (i've never seen one where the cord came out of the motor spot)
[23:22:16] <Jymmm> yeah 1" below the motor
[23:22:30] <Jymmm> Well, most the cord isn't removable either
[23:22:56] <Jymmm> I just spent $15 on it
[23:23:32] <Jymmm> SWPadnos: Try to avoid lesko (sp) fans, we had one and it fell over and one of the blades snapped off
[23:23:41] <SWPadnos> how annoying
[23:24:15] <Jymmm> Yeah, instant trash
[23:25:24] <SWPadnos> bbl
[23:25:55] <Jymmm> SWPadnos: LASKO, avoid it, but guess what lowes carries.
[23:26:19] <Jymmm> SWPadnos: $15.97
[23:26:28] <Jymmm> and 2500 CFM
[23:28:35] <JbLb> /msg NickServ identify
[23:46:39] <skunkworks711> I have put my finger into fans and had the blades come off. :)
