[00:01:32] <samkan> no, if it will done by X and Y then that's fine
[00:01:44] <samkan> but how can i generate correct g-code
[00:02:38] <samkan> here is the link for text engraving,
http://www.linuxcnc.org/index.php/english/component/kunena/?func=view&catid=20&id=20816, but I am looking for all the object, like test, vector..
[00:03:14] <uw> what did you make the deisgn in
[00:03:20] <uw> ?
[00:03:36] <uw> what cad program?
[00:04:12] <uw> you will most likely need a z axis too lift the bit off the surface
[00:05:13] <tjb1> how can you engrave with just x and y without moving the tool?
[00:06:02] <tjb1> engraving is just a pocket for wide items or a contour with no offset for cutter width engravings
[00:06:20] <samkan> Oh, sorry I do not have idea about engraving, was just asking you experts,
[00:06:22] <tjb1> programs that are built for engraving would generate the g-code for a specific design
[00:06:47] <tjb1> well a specific cutting design
[00:06:54] <samkan> ok, is there any program available on opensource
[00:07:57] <tjb1> maybe heekscnc
[00:07:57] <tjb1> http://code.google.com/p/heekscnc/
[00:08:03] <tjb1> never used it
[00:08:11] <tjb1> ive only used mastercam for g-code creation
[00:08:27] <ekacnet> pcw_home: on the 7I52 I can for every RS422 chan hook a 7I66-8 card ?
[00:08:44] <samkan> ok
[00:09:09] <tjb1> if you have a wide letter for instance you could just use a pocketing operation
[00:09:25] <tjb1> if you just want the cutting profile just use like a contour cut with no cutter comp/offset
[00:09:44] <tjb1> May not be called contour in heekscnc
[00:13:57] <pcw_home> ekacnet: yes
[00:15:04] <ekacnet> pcw_home: thanks a lot for your answers
[00:15:47] <pcw_home> You can also use 2 7I44s and connect 8 7I70s and 8 7I71s for 384 inputs and 384 outputs (though not with a 5I20 you need a 5I23 or > for this)
[00:17:06] <pcw_home> really bbl
[00:59:44] <uw> anybody have any ATC prefrences or recommendations?
[01:00:33] <Jymmm> Air Traffic Control? Fuses?
[01:01:16] <uw> sorrry thought it was a common term
[01:01:22] <uw> automatic tool changer
[01:01:48] <Jymmm> ah
[01:02:20] <uw> http://www.ebay.com/itm/CNC-Sherline-ATC-automatic-tool-changer-complete-system-with-controller-/230765448090
[01:02:25] <Jymmm> I failed my ATC entrance test by one question! bastards!
[01:02:26] <uw> i like that one but its too much money
[01:02:34] <uw> lol its all good
[01:02:53] <uw> i thought ATC ment "all terrain cycle" before i got into cnc not too long ago
[01:03:05] <uw> like my honda ATC250r i had when i was a kit
[01:03:08] <uw> kid
[01:03:13] <Jymmm> No it's not, I coulda been a freaked out person controlling thusands of lives flying around in the sky =)
[01:03:29] <Jymmm> ATV
[01:06:25] <Jymmm> oh wait, that is EVERY ATC that's ever been =)
[01:07:43] <Jymmm> uw: $1100 brand new, $600 ebay
[01:08:39] <Jymmm> sherline tool changer
http://www.cadcamcadcam.com/toolchanger.aspx
[01:09:10] <uw> yea thats still a little much though
[01:09:23] <uw> i was hoping in the 300-400 range
[01:09:40] <uw> and all i really want is the spindle and 2 tool holders
[01:10:29] <uw> not all of that other stuff
[01:17:22] <tjb1> http://sphotos.xx.fbcdn.net/hphotos-snc7/599635_3951072131212_1715253635_n.jpg
[01:17:27] <tjb1> what do you think of that
[01:24:03] <Jymmm> cant read it
[01:25:57] <tjb1> zoom it
[01:27:43] <tjb1> http://a2.sphotos.ak.fbcdn.net/hphotos-ak-ash4/456620_3554314972531_493994145_o.jpg
[01:27:45] <tjb1> oops
[01:36:01] <samkan> is it possible to use engraving with InkScape gcodetools extension?
[01:38:45] <uw> this channel isnt for that
[01:38:55] <uw> ask people at InkScape
[01:39:06] <samkan> ok
[01:40:06] <uw> tjb1, cool till i got to the arduino part
[01:40:26] <tjb1> dont like arduino?
[01:41:01] <uw> nope!
[01:41:11] <samkan> I am using graster for raster now after doing raster marking If i open some vector file like emc2, then no marking, i can see no value on pwm pin in helscope
[01:41:14] <uw> im guessing those other 2 things are ICs right?
[01:41:17] <tjb1> yeah
[01:41:28] <samkan> is it possible to do vector and raster with the same hal and ini file
[01:41:30] <Jymmm> samkan: uw Well, inkscape won't know, but most here are not using inkscape plugins for engravng, but it is potentially possible.
[01:41:33] <tjb1> does that look good to you?
[01:42:12] <samkan> I just read the thread over here..
[01:42:29] <uw> tjb1, I'm not sure what the dc/dc supply is
[01:42:30] <samkan> heekscns sounds good, heading to download it..
[01:42:34] <Jymmm> samkan: Raster? That is all up to your cad/graphics program, not really a CAM/cnc controller thing. All emc knows is gcode.
[01:42:52] <tjb1> its a isolated dc
[01:43:24] <samkan> yes, graster understand graphics and generate gcode out of it
[01:43:28] <Jymmm> tjb1: cant read it, post a clear one if you want others to view such things
[01:43:40] <uw> tjb1, so it that for boosting?
[01:44:00] <tjb1> isolates the arduino from that iso amp plasma cutter side
[01:44:17] <uw> why is the Vin+ connected to the Vin-?
[01:44:18] <samkan> emc2 understand gcode, it loads the graphics , but after raster images i am not able to do vector things
[01:44:59] <Jymmm> samkan: Again, not an emc/cam thing. thats YOUR grpahics/cad program.
[01:45:02] <tjb1> voltage divider uw
[01:45:27] * Jymmm chuckles... plasma isolation, tha'ts like saying isolating the salt from the ocean =)
[01:45:34] <uw> i cant really wrap my head around this, do you have a schematic?
[01:45:39] <tjb1> no
[01:45:40] <tjb1> lol
[01:45:59] <samkan> ok
[01:47:10] <tjb1> the dc/dc isolates the plasma side from the arduino
[01:47:15] <tjb1> because I cant get a common ground
[01:47:50] <tjb1> the 2k resistor steps the 7v down to 3.5 for the arduino
[01:48:06] <tjb1> the iso amp is isolating the plasma voltage from the analog input
[01:48:25] <uw> from this picture, i have no idea how the 2k resisitor does such a thing
[01:48:37] <uw> or what pin 6 and 5 are?
[01:48:39] <tjb1> there is a 2k resistor in the plasma cutter
[01:48:49] <uw> are you sure you couldnt make a schematic?
[01:48:51] <tjb1> pins 5 and 6 are the arc voltage output from the plasma cutter
[01:49:01] <samkan> for gecko540 i found the stepconf value, is it such available for panasonic servo motor? i am using panasonic servo motor but there is calibration problem?
[01:49:17] <samkan> means drawing size differ than actual
[01:49:31] <tjb1> Whats wrong with the current one uw :P
[01:49:51] <samkan> it is somehting like normal not realtime
[01:50:19] <uw> yes sure its a calibration problem
[01:50:37] <tjb1> What do you want in my schematic
[01:50:38] <uw> tjb1, maybe it's just late lol. it looks like a bunch of block diagrams
[01:50:46] <tjb1> it was done in draftsight
[01:50:53] <tjb1> i was tired of working on the damn thing lol
[01:50:54] <uw> what is the iso amp?
[01:51:03] <uw> just a comparitor or ??
[01:51:07] <tjb1> to isolate all of that garbage from the arduino
[01:51:18] <tjb1> those 2 chips are like a dividing line
[01:51:23] <tjb1> :P
[01:51:39] <uw> wo where is the +5v commming from , the arduino?
[01:51:40] <samkan> how can i get perfect stepconf value ?
[01:51:43] <tjb1> yes
[01:52:00] <samkan> i downloaded driver spec, but unable to do stepconf with that !
[01:52:02] <uw> so thats powering the dc/dc supply
[01:52:05] <tjb1> yes
[01:52:38] <uw> do you have a data sheet for this "iso amp"
[01:53:16] <tjb1> http://www.digikey.com/scripts/DkSearch/dksus.dll?vendor=0&keywords=ACPL-782T-000E
[01:54:21] <uw> ouch this little 8-DIP is $12?
[01:54:28] <tjb1> yeah
[01:54:41] <tjb1> the dc/dc is like $11
[01:54:53] <uw> yea thats another yolo
[01:55:02] <tjb1> yolo?
[01:55:04] <uw> so that stepps it up?
[01:55:09] <uw> the dc/dc?
[01:55:15] <tjb1> isolates it
[01:55:34] <uw> isnt there a cheaper way to do this?
[01:55:51] <uw> maybe with opticoupler and some gain transistors?
[01:56:05] <tjb1> im sticking with this
[01:56:08] <tjb1> ive had enough of this thing
[01:56:15] <tjb1> and i actually understand this :P
[01:56:24] <tjb1> and its still cheaper than the $600 dthc
[01:56:37] <uw> well, in that case, what are you waiting for?
[01:57:50] <uw> hmm ive never used this crazy isolation amplifier before. kinda neat device
[01:58:02] <Jymmm> what about a relay?
[01:58:06] <uw> for $12 though i dunno
[02:01:28] <tjb1> what am I waiting for?
[02:01:50] <uw> im sticking with thisand i actually understand this :P
[02:02:09] <tjb1> i dont have a table yet :P
[02:02:15] <uw> also so the plasma front is input to this iso amp?
[02:02:30] <tjb1> plasma front?
[02:02:39] <uw> pins 6 5
[02:02:45] <uw> i dunno what youd call it
[02:02:47] <tjb1> they are the arc voltage
[02:03:06] <uw> ok that is input to this iso amp?
[02:03:18] <tjb1> yes
[02:03:24] <tjb1> after it goes through the voltage divider
[02:03:48] <uw> i dont think that 2k resitor is deviding anything
[02:03:56] <tjb1> I explained this
[02:04:05] <tjb1> its working off the 2k resistor inside the plasma cutter :P
[02:04:38] <uw> which, doesnt happen to be in this drawing...
[02:04:48] <tjb1> yeah because I know its there
[02:04:54] <tjb1> and so do you
[02:04:56] <tjb1> :P
[02:05:14] <tjb1> http://sphotos.xx.fbcdn.net/hphotos-ash4/319786_3951014329767_1013097695_n.jpg
[02:05:17] <tjb1> there you go
[02:05:18] <uw> what else "do you know it's there" that isnt there in this drawing?
[02:05:26] <tjb1> the plasma cutter
[02:07:09] <uw> but it still that Vin+ is going to get slammed down by the short to Vin-
[02:07:16] <tjb1> its not a short
[02:07:20] <tjb1> its a voltage divider :P
[02:07:57] <uw> whats that soild line going from Vin+ to Vin-
[02:08:23] <tjb1> thats where it pulls the divided voltage
[02:08:56] <Jymmm> Well crap, I guess I have to make a heater after all =(
[02:09:16] <uw> so youre saying Vin+ will have a different value than Vin-?
[02:09:29] <tjb1> do you know how voltage divider works?
[02:09:45] <uw> yes
[02:10:03] <uw> if you are saying, Vin+ is going to be different than Vin-, you are wrong
[02:10:05] <uw> flat out
[02:10:09] <uw> no way
[02:10:26] <tjb1> goes pin 6 ---/\/\/\/\ ----Vin------pin 5---/\/\/\/\
[02:11:02] <uw> but ill give you this, youd make a great manager
[02:11:17] <Jymmm> rotf
[02:11:20] <uw> or director level, cause i almost believed you
[02:11:42] <Jymmm> uw: Of marketing or sales dept?
[02:12:10] <tjb1> well its a voltage divider...
[02:12:14] <uw> either one. Heck, even director of engineering at some places i work
[02:12:23] <uw> there is a voltage divider there
[02:12:24] <Jymmm> uwe_: you poor bastard
[02:12:30] <uw> but not between Vin+ and Vin-
[02:12:44] <tjb1> Vin- is ground
[02:12:53] <uw> so is Vin+
[02:13:19] <uw> careful tjb1, you lose mad credibility this way...
[02:13:24] <DJ9DJ> moin
[02:13:26] <tjb1> I didnt draw it.
[02:13:29] <tjb1> Well I drew it
[02:13:32] <tjb1> I didnt come up with it
[02:14:02] <uw> aahhh i see...
[02:14:10] <uw> yes you would make an EXCELLENT manager
[02:14:24] <tjb1> So you have no input on how to fix it?
[02:14:30] <Jymmm> and he peddles forward, then peddles backwards... come watch the amazing tjb1 the backpeddling wonder of the voltage divider world!!!
[02:14:42] <Jymmm> tjb1: ;)
[02:14:48] <tjb1> yeah funny funny
[02:14:57] <Jymmm> Yeah, it really is =)
[02:15:08] <uw> haha first i would get rid of the line between Vin+ and Vin-
[02:15:24] <tjb1> so how do you propose I get the voltage from 7 to 4
[02:16:17] <uw> is pin 6 going to be +7v?
[02:17:04] <mrsun> hmm, wonder how the quality of the china hss tooling is ... hss bar stock
[02:17:10] <tjb1> pin 6 to pin5 is 7v
[02:17:32] <uw> ok so pin 5 would be groundd...0v
[02:17:41] <uw> pin 6 would be +7v
[02:17:59] <uw> then that line between Vin+ and Vin- needs to be a resistor
[02:18:00] <tjb1> so I need another voltage divider outside ??
[02:18:21] <uw> if you made it 2k, Vin+ would be 3.5v
[02:18:37] <tjb1> is it safe to make it 5v...
[02:19:05] <uw> whoa whoa i have no idea here... pin 6 is 7v right?
[02:19:43] <tjb1> yes.
[02:19:58] <tjb1> the reason it was stepped to 3.5 was to allow "safety overhead"
[02:20:11] <tjb1> because the max input voltage of the arduino is 5v
[02:21:10] <tjb1> Looking at the diagram I think that 5 is the positive voltage
[02:21:13] <tjb1> and 6 is ground
[02:22:07] <tjb1> Is it?
[02:22:49] <uw> from the white background drawing it looks like 6 is + and 5 is -
[02:24:17] <uw> alright got to go to bed
[02:24:26] <uw> have a real job that i get paid to do tomorrow lol
[02:52:47] <heathmanc> so, if a person wanted to use dual feedback with a 5i20 and 7i77, what would they need for an additional card?
[02:55:24] <heathmanc> just a 7i52?
[03:03:38] <mrsun> for reaming, say a 12mm hole, what size of drill should i use before? :)
[03:03:45] <mrsun> 11.8 ? 11.9 ?
[03:04:57] <mrsun> only finding 11.8
[03:05:01] <mrsun> or 11.5
[03:06:06] <alex_joni> heathmanc: how many axes?
[03:06:20] <heathmanc> 3
[03:06:46] <heathmanc> i'm using 4 of the inputs on the 7i77, so it's not an option
[03:07:21] <alex_joni> you use the 7i77 on the 5i20?
[03:07:30] <alex_joni> or on a 5i25?
[03:07:32] <heathmanc> yes
[03:07:36] <heathmanc> 5i20
[03:07:44] <heathmanc> damn, i mean 7i48
[03:07:56] <heathmanc> must need some sleep
[03:08:32] <alex_joni> the 7i48 has 6 DAC and 6 encoder interfaces
[03:08:43] <alex_joni> isn't that enough for 2 x 3 ?
[03:08:46] <heathmanc> yes, and i'm using 4 of the encoder interfaces
[03:08:54] <heathmanc> got a spindle encoder
[03:09:21] <alex_joni> ahh, ok, it slowly clears up :D
[03:09:26] <heathmanc> i'm sorry
[03:10:12] <alex_joni> don't be ;) clearing up is always good
[03:10:46] <alex_joni> 7i52 sounds like a good fit
[03:10:57] <heathmanc> is it supported by emc?
[03:19:11] <alex_joni> heathmanc: now that beats me ;)
[03:20:41] <alex_joni> http://wiki.linuxcnc.org/cgi-bin/wiki.pl?Mesa_Cards
[03:20:53] <alex_joni> says there fully supported ;)
[03:29:31] <Jymmm> alex_joni: you're alive, I'll be damned
[03:32:30] <alex_joni> barely
[03:32:52] <Jymmm> heh
[03:33:01] <alex_joni> mostly still asleep :D
[03:33:51] <heathmanc> i'm assuming you can't use the pnfconf wizard when using that card
[03:34:33] <heathmanc> looks like it's time to dive in, this is my first emc experience
[03:35:28] <Jymmm> alex_joni: you dont do anything with plastics do you?
[03:35:31] <alex_joni> heathmanc: have a good one :)
[03:35:47] <alex_joni> Jymmm: like blow-up dolls? nope
[03:36:01] <heathmanc> you don't know what you're missing
[03:36:08] <Jymmm> alex_joni: like mold injection, extrusion
[03:36:12] <alex_joni> nope
[03:36:27] <alex_joni> nothing yet
[03:36:34] * alex_joni prefers metal
[03:36:57] <Jymmm> I don't know if I need a chemist or an engineer
[03:39:53] <alex_joni> there are people who are both..
[03:40:50] <Jymmm> mostly dealign with polymers and hydrocarbon materials
[03:55:11] <micges> heathmanc: 7i52 is for sure supported by linuxcnc
[03:55:35] <micges> (just checked source code)
[03:55:53] <heathmanc> is there a specific firmware i need for the 5i20/7i48/7i52 combo?
[03:56:49] <micges> you need 7i48 and 7i52 together?
[03:57:05] <heathmanc> yes, dual feedback, using 4 channels on the 7i48
[03:57:31] <micges> dual feedback on how many axes?
[03:57:35] <heathmanc> 3
[03:57:48] <micges> so you need 7 encoders 3 pwms?
[03:58:12] <heathmanc> yes, plus availablity for an A axis
[03:58:17] <heathmanc> so 8 encoders, 4 pwm
[03:59:01] <heathmanc> one of those 8 is a spindle encoder
[03:59:31] <micges> 5i25 + 2 x 7i77 is best price
[03:59:38] <micges> but if you want 5i20
[03:59:46] <heathmanc> i already have a 5i20 in the mail
[04:00:05] <micges> I see
[04:00:06] <heathmanc> the 5i25 wasn't available
[04:00:14] <heathmanc> on a 3 week backorder
[04:00:34] <micges> you're from usa?
[04:00:43] <heathmanc> yes
[04:00:46] <micges> ok
[04:00:56] <heathmanc> just not in the usa right now
[04:01:35] <micges> ah I remember - afghanistan
[04:01:47] <heathmanc> yes
[04:01:55] <heathmanc> i just want to have all the toys on hand i need when i get home
[04:05:22] <micges> best price would be 2 x 7i33
[04:06:06] <micges> you have drivers +-10V ?
[04:06:15] <heathmanc> yes, allen bradley ultra 3000 drives
[04:06:34] <heathmanc> not concerned about the price, and i already have a 5i20 and a 7i48
[04:07:10] <heathmanc> all i need is the encoder inputs
[04:07:46] <micges> if price doesn't matter, think what you will need in future
[04:08:06] <heathmanc> this is for a taig mill.. it's already overkill
[04:08:17] <heathmanc> then i should just get another 7i48
[04:09:56] <micges> you need also 7i37
[04:10:19] <heathmanc> i have the 7i37
[04:10:26] <heathmanc> using it for the 24v field i/o
[04:11:04] <mrsun> hmm, H7 is 0.0018 oversize? :/
[04:11:15] <mrsun> mm that is
[04:11:16] <mrsun> at 10mm
[04:11:48] <micges> heathmanc: ok so you know what you want
[04:12:05] <heathmanc> lol, or at least i think i do
[04:12:14] <micges> now you should check if 2x 7i48 fits 5i20 firmware
[04:12:48] <heathmanc> that's where the confusion begins
[04:13:13] <micges> you talked with PCW?
[04:13:24] <heathmanc> no i haven't
[04:14:06] <heathmanc> i think it fits, in the pnfconf, there is a sv12_2x7148_72 option
[04:14:08] <mrsun> my casting is a fail due to oversized hole :/
[04:15:16] <micges> yes I see that firmware
[04:15:29] <heathmanc> looks like it would work
[04:15:52] <heathmanc> any suggestions for a good mpg setup?
[04:18:51] <heathmanc> would i just be better suited to put in a pci parallel card and get a cnc4pc pendant?
[04:18:54] <Tom_itx> http://www.pmdx.com/MPG-01
[04:19:09] <Tom_itx> i made my own
[04:19:32] <Tom_itx> seems they're always out of stock on that now though
[04:19:52] <heathmanc> that's my luck
[04:21:44] <Tom_itx> http://tom-itx.dyndns.org:81/~webpage/cnc/pendant8.jpg
[04:23:06] <heathmanc> looks nice
[04:23:58] <Tom_itx> made from some surplus stamped aluminum box i found
[04:24:07] <heathmanc> so, in emc, i would need an input pin for each axis, and one for each division
[04:24:33] <Tom_itx> yes
[04:24:38] <Tom_itx> sort of
[04:24:40] <heathmanc> a separate input for each on the 7i37
[04:24:53] <Tom_itx> one division is on by default so you really only need 2 iirc
[04:25:03] <heathmanc> so 4 axis, plus 3 increments
[04:25:06] <Tom_itx> http://tom-itx.dyndns.org:81/~webpage/cnc/pendant.jpg
[04:25:08] <heathmanc> ok
[04:25:24] <heathmanc> so 6 pins for a pretty plain setup
[04:25:38] <heathmanc> plus estop
[04:25:40] <Tom_itx> something like that
[04:26:36] <Tom_itx> just depends what you want on it
[04:27:33] <Tom_itx> spindle, pause, estop, axis, division, mpg is what i have i think
[04:30:05] <heathmanc> http://www.cnc4pc.com/Store/osc/product_info.php?cPath=40&products_id=321
[04:30:23] <heathmanc> i would like to be able to integrate something like that, non usb of course, using the mesa
[04:30:37] <heathmanc> even if i have to add another one
[04:30:50] <Tom_itx> that one is usb isn't it?
[04:31:08] <heathmanc> yes, but i don't want to use this one, just something similar
[04:34:36] <heathmanc> the 7i73 seems perfect
[04:55:11] <heathmanc> Ok, so big question of the day, how do i get a firmware for a 5i20, 1x7i44, 1x7i37, 1x7i44, 2,7i73
[05:01:47] <cylly2> re @ home
[05:01:55] <Loetmichel> re @ home
[05:02:22] <Loetmichel> ahem, re @ work...
[05:02:37] <heathmanc> lol
[05:02:58] <Loetmichel> wromg /amg ;-)
[05:03:48] * micges bbb
[05:03:52] <heathmanc> where can a person find custom configuration firmwares?
[05:04:07] <heathmanc> hardware combinations
[05:06:23] <micges> you must compile it yourself
[05:06:46] <micges> http://git.linuxcnc.org/gitweb?p=hostmot2-firmware.git;a=summary
[05:08:47] <heathmanc> ouch
[05:09:05] <heathmanc> i'm not new to linux, but also haven't been using it for several years
[05:10:38] <heathmanc> so, in order to use all of the cards i have together, i have to complile a new firmware?
[05:13:24] <micges> when you order rest of boards, ask them for firmware you want
[06:04:14] <jthornton> heathmanc, if you catch pcw on here he might have what you need all ready
[06:05:10] * jthornton can't believe I slept so late today...
[06:05:12] <heathmanc> i'll be on the lookout
[07:11:53] <jthornton> anyone have an actual mack xml file from a mill laying about that they can post to filebin?
[09:17:31] <heathmanc> Anybody with any pokeys experience?
[09:17:55] <heathmanc> or different membrane type keypads
[10:01:17] <Jymmm> pokeys?
[10:03:09] <Jymmm> as in slang for jail?
[10:05:11] <heathmanc> Lol, i wan't to make an operator panel and need some membrane type keypads for it. I don't want to use the pokeys brain though
[10:05:31] <Jymmm> what is "pokeys" though?
[10:06:35] <heathmanc> http://www.cnc4pc.com/Store/osc/index.php?cPath=54&osCsid=82f25eee7ba6c42d4db852750fb8fd08
[10:07:44] <joe9> ReadError: which pc did you buy for the linuxcnc?
[10:08:05] <joe9> where did you buy it from? my pc just died/fried. need a new one. any suggestions/recommendations?
[10:08:54] <skunkworks> newegg usually has some pretty good deals
[10:09:00] <skunkworks> watch for free shipping also
[10:09:30] <joe9> ok, thanks. will check it out. is the Intel Atom D525MW still the most recommended pc for linuxcnc?
[10:11:18] <Jymmm> heathmanc:
http://www.ultimarc.com/ipac1.html
[10:11:49] <Jymmm> heathmanc: and has screw terminals
[10:12:56] <Jymmm> heathmanc: Once programmed, no software or drivers are needed as it emulates a usb/ps2 keyboard
[10:13:05] <heathmanc> that's slick
[10:13:28] <Jymmm> heathmanc: You can also pass-thru a real keyboard on soem models
[10:13:40] <heathmanc> but honestly, i'm looking for something more on the industrial side, if i could find an older panel to retro
[10:13:48] <heathmanc> but i've got some ideas for the ipac
[10:13:55] <heathmanc> for a different project
[10:13:55] <Jymmm> heathmanc: Can I ask why?
[10:14:12] <Jymmm> the dedicated buttons that is
[10:14:16] <skunkworks> heathmanc: Touch screen and the 'touchy' gui?
[10:14:37] <Jymmm> heathmanc: what skunkworks said as one idea
[10:15:11] <skunkworks> doesn't require a keyboard - but you do need a minumum amount of hardware buttons.
[10:15:35] <skunkworks> and a jog wheel I think
[10:15:47] <Jymmm> heathmanc: Hell, even one of these
http://www.dealextreme.com/p/foldable-flexible-compact-waterproof-usb-silicone-keyboard-color-assorted-85-keys-55897
[10:15:49] <heathmanc> that would work, I ordered a 7i44 and 7i73 for a membrane type setup, but i have an industrial 15" touchscreen
[10:16:39] <Jymmm> heathmanc: or this
http://www.dealextreme.com/p/usb-ps2-black-ultraslim-flexible-washable-dustproof-keyboard-indestructible-1845
[10:16:55] <heathmanc> is touchy fairly configurable?
[10:18:57] <ReadError> joe9: yea atom d525
[10:19:07] <joe9> ReadError: where did you buy it from?
[10:19:11] <ReadError> got it from amazon
[10:19:14] <ReadError> since i have prime
[10:19:16] <ReadError> 3.99 overnight
[10:19:33] <joe9> ReadError: do you know if it supports coreboot (bios)?
[10:19:38] <cradek> keyboard emulators make a lousy control panel. you have all the issues of mouse focus, which window is on top, etc. halui is a much better solution.
[10:19:48] <joe9> i could not find anything on the coreboot website.
[10:19:51] <ReadError> not sure joe9
[10:19:59] <Jymmm> joe9:
http://www.newegg.com/Product/Product.aspx?Item=N82E16813121442
[10:19:59] <ReadError> never messed with coreboot
[10:20:02] <heathmanc> i don't really want to use a keyboard umulator, that's why i got the 7i73
[10:20:07] <heathmanc> two of them actually
[10:20:17] <joe9> Jymmm: thakns.
[10:20:20] <joe9> thanks
[10:20:27] <skunkworks> heathmanc: I have not used touchy.. cradek wrote it though... ;)
[10:20:34] <Jymmm> joe9: or if yu want somethng really slick....
[10:21:08] <skunkworks> cradek: are you using touchy on your lathe?
[10:21:13] <joe9> ReadError: no latency issues, I presume.
[10:21:20] <ReadError> joe9: nope
[10:21:20] <Jymmm> joe9: Runs on 8-19VDC DIRECTLY and is only 3/4" tall, but only a PCIe 1x slot
http://www.mini-box.com/Intel-DN2800MT-Mini-ITX-Motherboard
[10:21:25] <joe9> Jymmm: ok, thanks.
[10:21:31] <ReadError> but browseing youtube and stuff is pretty slow
[10:21:33] <cradek> skunkworks: not yet
[10:21:39] <ReadError> compared to the core2duo i had before
[10:21:49] <ReadError> but latency is really low
[10:21:55] <joe9> ReadError: i just want it to be a headless machine. so no youtube for me on that.
[10:22:31] <ReadError> oh yea
[10:22:35] <ReadError> it will work well than
[10:23:02] <joe9> Jymmm: love that concept of using DC jack's. makes things so much more easier.
[10:23:02] <ReadError> i had just upgraded the ram in my macbook
[10:23:07] <ReadError> so i had 4gb to put in it
[10:23:43] <Jymmm> joe9: Yeah =) Thee is also an on-board molex connector so you dont have to run power out of the rear coaxal jack too
[10:23:56] <pcw_home> heathmanc: if you want a 7I44 you are better off with a 5I23, as the 5I20 does not have enough space for 8 sserial channels plus the servo control
[10:23:56] <Jymmm> they are electrically the same
[10:24:28] <heathmanc> ouch
[10:24:55] <heathmanc> so 3 ports won't run the 7i48, 7i37, and 7i44
[10:25:27] <joe9> Jymmm: that "Intel DN2800MT Mini-ITX" is just $40
[10:25:30] <pcw_home> not with all 8 sserial channels (probably OK with 4)
[10:25:42] <heathmanc> i'm only going to use two channels at most
[10:25:44] <Jymmm> joe9: link?
[10:26:05] <heathmanc> and probably only one realistacly
[10:26:05] <joe9> Jymmm: sorry, that was the case.
[10:26:12] <Jymmm> joe9: =)
[10:26:31] <Jymmm> joe9: But if you DO find it for $40 let me know =)
[10:26:40] <joe9> ok, will do.
[10:27:15] <Jymmm> joe9: It has an LVDS connector on it too. and I have a 17" dead laptop that would be perfect for gutting =)
[10:27:16] <heathmanc> pcw_home: BTW, do you have a firmware for a setup like that?
[10:27:42] <joe9> Jymmm: what is the use of an LVDS connector?
[10:27:52] <joe9> if you do not mind me asking.
[10:27:59] <Jymmm> joe9: Direct LCD panel connection
[10:28:07] <joe9> oh, ok. thanks.
[10:30:56] <Jymmm> You know what would be slick... Using a 7 or 10" Android tablet as a "touch screen" =)
[10:33:26] <joe9> ReadError: do you know if yours has a slot for the IDE cable?
[10:33:35] <joe9> the parallel port IDE, I mean.
[10:33:40] <Jymmm> joe9: IDE?!
[10:33:50] <Jymmm> IDE is ancient HDD =)
[10:34:05] <joe9> i have a bunch of IDE disks around.
[10:34:14] <Jymmm> joe9: No
[10:34:20] <Jymmm> joe9: No No No
[10:34:30] <Jymmm> joe9: Just say No to ide!
[10:34:40] <joe9> ha ha..
[10:35:13] <Jymmm> joe9: If/when you have to replace it, you probably won't find one.
[10:35:27] <joe9> i read that I should make sure that the Parallel Port is EPP capable to run with linuxcnc. Is that correct?
[10:35:29] <Jymmm> joe9: If you are going to buy a new mobo, get sata
[10:35:34] <ReadError> joe9: nope
[10:35:36] <ReadError> no ide
[10:35:56] <ReadError> it does support EPP
[10:36:16] <joe9> http://www.mini-box.com/Intel-D2500HN-Mini-ITX-Motherboard is priced cheaper than the
http://www.amazon.com/Intel-Dual-Core-Mini-ITX-Motherboard-BOXD525MW/dp/tech-data/B0041RSC94/ref=de_a_smtd/175-1978493-1927128
[10:38:20] <joe9> sorry, wrong cost. i am having trouble with newegg and links.
[10:38:26] <joe9> need to switch to firefox.
[10:39:57] <Jymmm> joe9: If you are going to get a mobo that nobody has tested here for latency, at least check out newegg's reviews for it.
[10:40:12] <joe9> good idea. thanks.
[10:43:24] <Connor> okay, so is there a way to get touchy to show the simulated paths like axis does ?
[10:45:31] <ReadError> joe9
[10:45:39] <ReadError> the benefit to the d525, is its tried and true
[10:45:51] <ReadError> known compatability and low latency
[10:46:03] <joe9> yeah, that makes sense. i am better off sticking with it.
[10:46:08] <joe9> what about the PSU?
[10:46:12] <ReadError> also regarding the HD issue
[10:46:24] <ReadError> you could always run it on a 16gb flash drive
[10:46:31] <ReadError> since i doubt much i/o is going to take place
[10:46:39] <ReadError> maybe even 8 if you strip it down
[10:46:48] <ReadError> i use an old ATX PSU/CASE
[10:47:13] <joe9> ReadError: regarding the psu, no issues with psu connectors?
[10:47:24] <joe9> i have a few psu's lying around.
[10:47:24] <ReadError> nope
[10:47:33] <joe9> cool, thanks.
[10:47:34] <ReadError> its an olllllld antec PSU
[10:47:38] <ReadError> but still has a p4 plug
[10:47:56] <ReadError> now, the switch pinout is a bit different
[10:48:10] <ReadError> but it will still work
[10:48:17] <ReadError> i think HD LED i didnt have plugged in..
[10:48:59] <joe9> ReadError: how much ram did you put in there?
[10:49:05] <ReadError> 4gb
[10:55:18] <skunkworks> Connor: I think can creat a tab with the preview from axis. Look at the glade examples in the sample configs
[10:55:41] <Connor> okay. That's what I was thinking.
[10:56:13] <skunkworks> in the glade sample configs - there is a touchy config with a 'plot' tab
[10:56:22] <Connor> requires external controls to do cycle start/stop and jog..
[10:56:36] <skunkworks> yes
[10:59:00] <Tom_itx> progress:
http://tom-itx.dyndns.org:81/~webpage/cnc/psu/control2.jpg
[11:02:07] <Jymmm> Tom_itx: you had to remount the caps???
[11:02:19] <Jymmm> oh the xmfrs too =(
[11:03:46] <Tom_itx> it was planned that way
[11:03:50] <Tom_itx> the first was test
[11:03:55] <Jymmm> Tom_itx: what is that pcb just above teh terminal strip for?
[11:04:16] <Tom_itx> 5v smps for the mesa cards
[11:04:24] <Jymmm> amp?
[11:04:30] <Tom_itx> 2.5-3
[11:04:35] <heathmanc> which cards are you using?
[11:04:36] <Jymmm> VR?
[11:04:51] <Tom_itx> ?
[11:04:57] <Jymmm> voltage regulator?
[11:05:00] <Tom_itx> voltage regulator or variable regulation?
[11:05:02] <Tom_itx> yes
[11:05:06] <Jymmm> k
[11:05:10] <Tom_itx> takes 25v down to 5
[11:05:13] <Jymmm> ah
[11:05:31] <Tom_itx> i had to tap in at the centertap because the input to it wouldn't take the full 50v
[11:05:41] <Tom_itx> that's what the extra cap in the middle is for
[11:05:49] <Tom_itx> but it's gonna get remounted too
[11:05:50] <Jymmm> ah
[11:06:01] <Tom_itx> there's a diode in the wire
[11:06:02] <Jymmm> I liked the C-Channel perosnally
[11:06:27] <Tom_itx> this has been made from 80% recycled materials
[11:06:34] <Tom_itx> surplus anyway
[11:06:45] <Jymmm> Did you HAVE to recycle the beige paint too? lol
[11:06:55] <Tom_itx> i don't like that either
[11:06:59] <Jymmm> =)
[11:07:03] <Tom_itx> it was a control box for some UV equipment
[11:07:14] <Jymmm> and you dont have any spray paint?
[11:07:15] <Tom_itx> from califor i a
[11:07:24] <Tom_itx> purple
[11:07:31] <Jymmm> hey, whatever works =)
[11:07:46] <Jymmm> pink for all I care, but not beige!
[11:07:59] <Tom_itx> it was originally grey
[11:08:06] <Jymmm> and it's not even a nice beige either
[11:08:11] <Tom_itx> you can see where i swapped the hinges to the other side
[11:08:14] <Jymmm> grey I think would have been better
[11:08:24] <Jymmm> ah, yeah
[11:08:50] <Tom_itx> i'll go have it powder coated just for you
[11:09:19] <Jymmm> It just looks so, um, aged (?) with that color. Something from the 70's
[11:09:20] <Tom_itx> i think i'll go with the old Gateway box paint job
[11:09:27] <Tom_itx> the 'cow' theme
[11:09:44] <Jymmm> cammo-cow!
[11:10:10] <Jymmm> kinda like "whers waldo", but bovine themed!
[11:10:37] <Tom_itx> i bit the bullet on the wire today
[11:10:42] <Tom_itx> i'll start on that later on
[11:10:49] <Jymmm> Tom_itx: hello ebay!
[11:10:56] <Jymmm> or CL
[11:11:31] <Jymmm> Tom_itx: I see the fan, but where's the vent?
[11:11:40] <Tom_itx> not cut yet
[11:11:48] <Tom_itx> or i may get some feet and use the bottom holes
[11:11:52] <Jymmm> gotcha. Looking good =)
[11:12:15] <Tom_itx> i'm thinking the holes would be a natural repurpose for a vent
[11:12:39] <Tom_itx> http://tom-itx.dyndns.org:81/~webpage/cnc/psu/box1.jpg
[11:12:49] <Tom_itx> right under the transformers
[11:13:12] <Jymmm> perfect, but add a filter
[11:13:35] <Jymmm> no need for it looking like the inside of a PC after a coule of years
[11:13:54] <Tom_itx> that's why i got a 5hp 80 gal compressor
[11:14:04] <Jymmm> just something you can get off the shelf at the big orange or blue borg
[11:14:20] <Jymmm> yeah but you'll get lazy and not use =)
[11:14:43] <Tom_itx> i got some of the white ones
[11:14:54] <Jymmm> there ya go
[11:15:07] <Tom_itx> more 'cloth' to them than the cheapos
[11:15:36] <Jymmm> could even make a bracket so it just slides in/out like on HVAC unts
[11:15:58] <Jymmm> less chance for being too lazy to replace it =)
[11:16:01] <Tom_itx> i said i'd put one in, i didn't say i'd change it
[11:16:44] <Jymmm> I know =) I'm think ahead here. "Oh I dont want to change the filter, I need a wrench and it's 2 feet out of reach on that bench over there"
[11:17:22] <Tom_itx> i don't see why this box wasn't moisture rated. it's got a rubber seal on the door
[11:17:39] <Jymmm> it has holes in it? lol
[11:17:57] <Tom_itx> they had water tight connectors in them when i got it
[11:18:03] <Jymmm> ah

[12:18:33] <IchGuckLive> Question on ELKO near the Driver someone has good experiance on that or live it on the meanwel powersorce internal elkos
[12:19:09] <ReadError> archivist: thats in atlanta ;)
[12:19:20] <IchGuckLive> i got 5 4,2A stages running al at the same time at 500W
[12:19:44] <IchGuckLive> meanwell powersorce leadshine 542
[12:24:42] <IchGuckLive> pcw problem with the 5i25 7i76 setup the leadshine takes a driver enable signal ,As i on 12V Vin for the PNP indicators for in output THERE are only STEPDIR on 5V available
[12:24:45] <Loetmichel> hmmm
[12:24:52] <Loetmichel> re @ home
[12:25:26] <Loetmichel> anyone can name a usa state with P... other than philadelpia? i wonder where my wife is just now...
[12:25:55] <ReadError> pennsylvania
[12:26:11] <Loetmichel> was in Vancouver last week, had flown to philly on thursday and should be on the plane to p... now....
[12:26:18] <heathmanc> Philly isn't a state....
[12:26:25] <Loetmichel> taht wasnt it either
[12:26:31] <ReadError> lol
[12:26:38] <ReadError> theres no other state that starts with a p :)
[12:26:49] <Loetmichel> philadelphia is a city, i know...
[12:27:21] <Loetmichel> ba, my geographic knowledge is on a VERY low level :-(
[12:27:26] <Loetmichel> ... and my memory also
[12:28:09] <Loetmichel> i whish i could rememer where she said she is flying to
[12:29:00] <Loetmichel> hmmm, maybe google helps... *searching for SAP dependancies in the us of a;)
[12:32:15] <IchGuckLive> pcw so i guess i run from OUT XV to the leadshine Enable and with a resistor 1K to grnd AS Commen Anode ??
[12:33:28] <IchGuckLive> pcw ?
[12:35:33] <IchGuckLive> pcw_home: ?
[12:38:00] <Loetmichel> ... ah, i think it was phoenix.. sounds familliar...
[12:39:39] <heathmanc> lol
[12:39:41] <alex4nder> hey
[12:41:53] <IchGuckLive> today i got stuff for another 5Mashines 2x3,1x4 and 2x5 axis
[12:44:40] <Jymmm> IchGuckLive: But do you have at least one machine up and fully operational yet is the question
[12:49:09] <IchGuckLive> i got over 50 running
[12:49:51] <IchGuckLive> from mini 4x4x2inch to 7x3x3Meter
[12:53:10] <pcw_home> Lead shine has active low enable?
[12:54:16] <IchGuckLive> i donmt think i made that yet as im still putting all togeter
[12:54:54] <IchGuckLive> the step/Dit is positiv isent it
[12:55:00] <IchGuckLive> Step/dir
[12:55:32] <IchGuckLive> and the output also positiv so no active low
[12:56:31] <IchGuckLive> http://www.leadshine.com/UploadFile/Down/M542m.pdf
[12:56:48] <IchGuckLive> on page 4
[12:57:41] <IchGuckLive> Step/Dir goes Bidirectional to 7i76
[12:59:26] <IchGuckLive> pcw_home: as the output can Drive 300mA i will go output5 to all 5Axis Drivers to Enable them
[12:59:27] <IchGuckLive>
[13:03:03] <pcw_home> Yes you can do that (with suitable resistor for 12 or 24 V)
[13:14:32] <IchGuckLive> so i guess on monday first run of the 5i25-7i76 combination
[13:17:18] <IchGuckLive> is there anywhere a selfmade spindelencoder to look how this is is done by gear or somthing to get the needed precision
[13:17:31] <IchGuckLive> i got no idee
[13:18:32] <IchGuckLive> direct connect will need a big encoder CPR
[13:20:12] <pcw_home> A spindle encoder normally does not need a very high CPR
[13:20:16] <IchGuckLive> wit a 1000CPR to get good system as spindel turns around 6Krpm or disconnect during turning and reconnect to use as axis
[13:21:32] <IchGuckLive> pcw_home: infact as a RPM meter it needs only index
[13:22:05] <pcw_home> if its a direct axis then it wants quite high CPR 64000 is not too high
[13:23:10] <IchGuckLive> i need to have a look on this there are shure encoders out there that can handle this but at high cost
[13:23:27] <pcw_home> but a high res encoder will liklly not work at 6000 RPM
[13:23:52] <Loetmichel> PCW: the encoder itself will
[13:24:16] <Loetmichel> but the electronics behind may have some problems with MHz clock pulses
[13:24:32] <pcw_home> No the detector will not
[13:24:44] <IchGuckLive> therfor i guess is setup at index pulse RPM meter and wit a Mcode bring a worm gear encoder in
[13:24:54] <Loetmichel> normal photo diodes go easily upt o 2 digit Mhz
[13:25:10] <Loetmichel> maybe not with the full voltage swing but still they go
[13:25:18] <pcw_home> sorry no
[13:25:27] <Loetmichel> if the amplifiers in the encoders can cope with that...
[13:25:57] <IchGuckLive> ok im off thanks to all your answers
[13:26:55] <Loetmichel> hmmm, may have to check that with some reflex detectors i have here, but i think i have used some reflex detectors with optics as a sortrange 100Mbit data "laser"
[13:27:00] <Loetmichel> shortrange
[13:27:23] <Loetmichel> but they were naked led and photodiode in one casing
[13:27:45] <Loetmichel> no electronics in the detector casing
[13:28:18] <pcw_home> Much easier with a laser
[13:28:43] <Jymmm> ...and a shark to mount it on
[13:28:57] <pcw_home> normal encoder detectors have to compromise detector area vs speed
[13:29:19] <Jymmm> compromise?
[13:29:28] <Loetmichel> shark?
[13:29:30] <Jymmm> speed vs precision?
[13:29:40] <pcw_home> you have a diffuse light source
[13:29:44] <Jymmm> Loetmichel: Austin Powers refernce
[13:29:47] <Loetmichel> ah
[13:29:52] <Loetmichel> sorry, never seen that
[13:30:20] <Jymmm> Loetmichel:
http://www.youtube.com/watch?v=Bh7bYNAHXxw
[13:31:45] <pcw_home> Some higher res enccoders pulse the LED to get enough signal
[13:32:07] <Loetmichel> Jymmm: ah, now i remember why i didnt look that film
[13:32:11] <Loetmichel> ;-)
[13:32:37] <Loetmichel> pcw_home: possible abd tha the speed is limited, granted
[13:32:41] <Loetmichel> and then
[13:33:19] <pcw_home> If you look at standard encoders most top out at a few hundred KHz
[13:34:58] <pcw_home> laser encoders can be much faster but most are absolute/pseudo absolute (serial vs quadrature interface)
[13:35:23] <Jymmm> Loetmichel: it's not THAT bad =)
[13:36:18] <pcw_home> its supposed to be bad...
[13:36:55] <Jymmm> well in a cheesy sorta way =)
[13:40:26] * Tom_itx passes out pizza bribes for later favors he will collect
[13:41:59] <pcw_home> Wheres mine?
[13:42:12] <Tom_itx> i'm bettin Jymmm stole it
[13:44:03] <andypugh> Woot!
http://www.ebay.co.uk/itm/120934176878
[13:44:15] <andypugh> (Not even sure what I want it for)
[13:44:51] <JT-Shop> make your Near a Car electric!
[13:45:43] <Loetmichel> JT-Shop: merely 10 times to small ;-)
[13:46:44] <Loetmichel> but looks fitting for the toddlers bobby car
[13:46:49] <Loetmichel> ;-)
[13:46:56] <pcw_home> will the seller actually ship it?
[13:47:24] <andypugh> I don't know. I feel obscurely guilty about asking him to.
[13:47:31] <Loetmichel> <- just in the process of fitting two(!) 1kw brushless motors to wifeys wheelchair ;-)
[13:53:04] <andypugh> Loetmichel: Differentially steered?
[13:53:36] <andypugh> It would be relatively simple to drive a wheelchair by G-code. "Load the going to the shops program"
[13:53:37] <Loetmichel> correct
[13:53:54] <pcw_home> Is that 1KW peak or continuous?
[13:53:56] <pcw_home> Normal industrial brushless motors can deliver ~3 X their rating for a number of minutes
[13:54:01] <Loetmichel> continous
[13:54:15] <Loetmichel> (for about 15 min, then the batteries will be dead)
[13:54:28] <andypugh> A gyro might be useful, as used to keep model helicopters going in straight lines.
[13:54:50] <pcw_home> OK so they are about 300 W industrial size
[13:55:37] <Loetmichel> willbe steered with a wii nunchuck
[13:55:54] <uw> sounds like quite a project
[13:56:15] <andypugh> Sounds very similar to building a robotwars robot.
[13:56:25] <Loetmichel> the joystick for fwd/reverse/steering and the two keys for "deadman" and two speed ranges
[13:56:46] <uw> how far along are you with this?
[13:57:02] <Loetmichel> so i dont have to shove her through walmart again..
[13:57:19] <Loetmichel> got the motors and are building the contorllers at the moment
[13:57:40] <Loetmichel> (waitig for a friebnd to modify model brishless controlelrs to fwd/reverse)
[13:57:47] <Loetmichel> the software
[13:57:59] <uw> andypugh, that a good find!
[13:58:10] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=13370
[13:58:43] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=13373 <- atm there is TWO millimeter to less room in the motors for the magnets...
[13:58:55] <Loetmichel> am thinking to make a new bell
[13:59:08] <Loetmichel> or grinding the magnets a bit trapezoidal
[13:59:15] <andypugh> Loetmichel: Definitely look at integrting a gyro then. The controller will probably connect directly.
[13:59:47] <Loetmichel> gyro for what?
[14:00:04] <Loetmichel> steering or limiting thrust so she dont topples over?
[14:00:13] <andypugh> Heading-keeping
[14:00:21] <Loetmichel> dont thinks so
[14:00:33] <Loetmichel> that can be done by the driver ;-)
[14:00:54] <andypugh> There is a tendency for differentially-steered machines to skew alarmingly if one wheel slips or hits an obstacle.,
[14:01:16] <andypugh> A gyro is almost de-rigeur for 2-wheeled robots.
[14:01:26] <uw> id be interested in this project, when it's finished
[14:02:27] <uw> also why using a wiimote?
[14:02:30] <uw> novelty?
[14:02:42] <Loetmichel> not a wiimote
[14:02:50] <Loetmichel> the other half
[14:03:07] <Loetmichel> the little "egg" with the little joystick and the two buttons
[14:03:11] <andypugh> Gyros are pretty cheap.
http://www.hobbyking.com/hobbycity/store/%5F%5F15318%5F%5FHobbyKing%5FGA%5F250%5FMINI%5FMEMS%5FGyro%5F.html
[14:03:28] <Loetmichel> because its cheap and fits easyly to the armrest
[14:03:54] <uw> ok i see, just the stick part of it
[14:03:57] <Loetmichel> andypugh: jeah, i have enough gyrosensors here, being a quadcopter pilot ;-)
[14:04:18] <andypugh> Ah, OK.
[14:04:42] <Loetmichel> maybe i integrate one in the main controller
[14:04:47] <uw> so youre not using bluetooth or anything to get the sitck position right?
[14:04:50] <Loetmichel> but i doubt it necessary
[14:05:08] <andypugh> Have you seen:
http://vimeo.com/33713231
[14:05:18] <Loetmichel> it should be limited to 20km/h (on "highspeed") anyway
[14:05:31] <Loetmichel> andypugh: yes
[14:05:58] <Loetmichel> but i dont fly autonomous, i dont even own a gps for the copter
[14:06:11] <uw> anything as in, any of the nintendo protocol, just analog control
[14:06:46] <Loetmichel> i just use it for fun, some inflight videos and FPV, and of vouse the occasion night "ufo sighting" provoke ;-)
[14:06:58] <Loetmichel> s/vouse/course
[14:07:41] <Loetmichel> uw: no, just connect the sick directly to the main controller and read it out
[14:07:58] <Loetmichel> uw: you know "KISS"?
[14:08:26] <uw> ah ok, thats a good way to do it.
[14:08:33] <uw> the band?
[14:08:37] <Loetmichel> why use protocols and transmitters when a wire is no problem and more reliable?
[14:08:53] <Loetmichel> "Keep It Simple, Stupid!"
[14:09:03] <uw> no disagreement, you're doing the right thing ;)
[14:09:33] <uw> i was going to criticize you using the wii motes bluetooth, but you arent, so thats cool
[14:09:35] <Loetmichel> the controller o bought lately in the grovery store had cost about 6 eur.
[14:09:42] <uw> esp something like a wheelchair
[14:09:43] <Loetmichel> and is nicely shaped for a hand
[14:10:08] <Loetmichel> uw: ESPECIALLY with my wife sittin in it ;-)
[14:12:08] <Loetmichel> the problem is more to let the wheelchair still fold after fitting the motors, the electronics and the 4 12V 7A lead-acid blocks
[14:12:31] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=9059
[14:12:40] <uw> oh so its a standard wheelchair, not an already electric wheelchai
[14:12:42] <Loetmichel> not much room underneth there
[14:12:47] <Loetmichel> it is ;-)
[14:13:20] <Loetmichel> it has to fold at least 50% in the with or it will not fit in the car
[14:13:38] <Loetmichel> yes, my wife CAN walk a few steps. and drive a car
[14:13:42] <uw> haha yea, lead batteries kinda take the whole "portiableness" out of things
[14:13:58] <Loetmichel> ... and it shouldnt get to heavy for her to lift into the back of the car
[14:14:23] <uw> that or have the battries quick removable so she can pull them out indivitually
[14:15:13] <uw> but that may be too much work to impliment
[14:15:31] <Loetmichel> it will be mostly for my wife buying grocerys without pain in her damaged hip joint
[14:16:07] <Loetmichel> so she can drive around in the store instad of sohoving a shopping cart around and have to fiddle with the crutches
[14:16:42] <uw> understood. well hopefully she recovers soon so she wont have to use either!
[14:17:02] <Loetmichel> so the 4 bartterys 12V 7Ah are a compromise
[14:17:19] <Loetmichel> thats 336Wh
[14:17:36] <uw> that should be decent
[14:17:39] <Loetmichel> that should be enough for about one hour of "walking around"
[14:17:54] <uw> aslong as she doesnt start doing burnouts or extreme sports with it ;)
[14:17:56] <Loetmichel> or 15 minutes of "pedal to the metal" ;-)
[14:19:06] <Loetmichel> and its only temporary
[14:20:12] <Loetmichel> as sonn as she hits the 200lbs on her diet the docs will fit her a new hip joint . then the wheelchair and the chrutches will hopefully obsolete
[14:20:19] <Loetmichel> soon
[14:21:37] <andypugh> This all looks vaguely old-school and expensive:
https://picasaweb.google.com/lh/photo/OayQVi20BPHUTjIjoR7dFdMTjNZETYmyPJy0liipFm0?feat=directlink
[14:23:04] <Loetmichel> looks like some kind of midi-controller or something
[14:23:51] <Loetmichel> and not SO oldschool: smt components involved ;-)
[14:23:55] <andypugh> It's one of these:
http://en.wikipedia.org/wiki/Dial_box
[14:24:46] <Loetmichel> ah, close but no cigar
[14:24:57] <andypugh> There were 6 in the skip at work. By the time it was late enough to unobtrusively rescue them I could only get to 2.
[14:24:58] <Loetmichel> but the midi controllers are not that different
[14:25:21] <Loetmichel> andypugh: what a waste
[14:25:27] <Loetmichel> these look really nice
[14:26:13] <andypugh> The SGI workstation and flat-panel display (with remvable backlight so it could be used on an overhead projector) was more of a waste.
[14:27:55] <Jymmm> andypugh: Not really, sales engineers used them ALOT
[14:28:09] <andypugh> http://uk.rs-online.com/web/p/cable-conduits/0185980/ is expensive, and I only need half a meter. I wonder how well
http://www.ebay.co.uk/itm/300728850204 would work?
[14:28:13] <Jymmm> andypugh: IBM Thinkpad had the same thing, $8000 USD at the time
[14:28:38] <andypugh> Jymmm: Yes, exactly, a shame to see it tossed in the skip.
[14:28:50] <Jymmm> andypugh: you really dont have hardware stores that sell by the foot?
[14:28:59] <andypugh> Not that I have found.
[14:29:07] <andypugh> And I did a tour today.
[14:29:13] <Jymmm> andypugh: did you try an electric contractor?
[14:29:26] <Jymmm> they probably have some in theur skip
[14:29:27] <cradek> I wonder why there are two concentric sets of holes on those encoders
[14:29:33] <andypugh> 20mm and 25mm are easily available.
[14:30:01] <andypugh> cradek: I wondered that too. Perhaps they only had big, unfocussed detectors?
[14:30:08] <Jymmm> andypugh: Well, use two 25mm then
[14:30:31] <andypugh> I would need 4
[14:30:43] <pcw_home> yeah no Ronchi plate so 90 degree slot sets
[14:30:46] <Jymmm> ok, four
[14:31:12] <Jymmm> andypugh: that kind of money for just a meter, not worth it
[14:32:03] <Jymmm> has anyone melted hdpe?
[14:32:50] <Loetmichel> the two rings: maybe using it to enhance resolution
[14:33:24] <Loetmichel> if you have a slit plate in front of the transostors wou woud geht a pulse from each hole
[14:33:46] <pcw_home> IF you dont have a Ronchi/resolver plate you need 2 sets of slots
[14:34:29] <Loetmichel> pcw_home: you also can set the 2 recivers exactly 90° phase shiftet
[14:34:32] <Loetmichel> -t
[14:34:37] <Loetmichel> on a single ring
[14:34:49] <pcw_home> yes that works for coarse slots
[14:35:10] <pcw_home> I think these are on the edge
[14:36:00] <pcw_home> high res encoders use a single set of slots and a Ronchi/resolver plate
[14:36:10] <Loetmichel> hmmm
[14:36:49] <pcw_home> (or differential photodiode arrays)
[14:36:56] <archivist> andypugh, there are shortish flexible basin drain pipe that could be re-purposed B&Q wickes
[14:37:03] <Loetmichel> i made me some with this templates:
http://www.cyrom.org/palbum/main.php?g2_view=core.DownloadItem&g2_itemId=263
[14:37:28] <Loetmichel> the black one fixed, the white one rotating
[14:37:59] <Loetmichel> and then put a detector on each side and two led underneath
[14:38:04] <Loetmichel> worked like a charm
[14:38:45] <pcw_home> That is how most standard optical encoders work
[14:39:04] <pcw_home> though the disk and resolver are often glass
[14:41:28] <Loetmichel> i made mine of 0,3mmm brass and etched them
[14:46:54] <pcw_home> yeah some commercial ones (maybe up 500 line or so) use thin stainless steel both for the disk and the resolver
[14:48:32] <pcw_home> finest ones I have seen use metal on glass (probably some photo process like wafer mask tech)
[14:49:44] <pcw_home> Ive made some with graphic film on 6 mil mylar
[14:52:44] <Loetmichel> pcw_home: the silver on glass can be bouhgt for chap at any stage supplier. as "gobos" fit the moving lamps
[14:52:58] <Loetmichel> and custom picture on it
[14:53:02] <Loetmichel> etched in
[14:53:20] <pcw_home> and Andy found that the SMT stencil people can make decent stainless steel ones fairly cheap
[14:53:44] <pcw_home> (the stencil business is pretty competitive)
[14:59:45] <andypugh> archivist: I want something that will resist me dropping sharp-edged components onto it.
[15:00:14] <Loetmichel> andypugh: linoleum?
[15:00:24] <Loetmichel> for a table lining, or what?
[15:00:31] <andypugh> As a cable conduit
[15:00:35] <Loetmichel> ah
[15:01:17] <Loetmichel> there is a vacuum hose with a kevelar "spring" in it
[15:01:26] <Loetmichel> maybe that would be sufficient?
[15:01:54] <Loetmichel> s/vacuum hose/suction side hose for well pumps
[15:02:24] <archivist> andypugh, depends how sharp and heavy :)
[15:02:54] <Loetmichel> i would definetly not go for steel/metal
[15:03:03] <andypugh> Yes. I realise there are limits
[15:03:14] <Loetmichel> will be deformed if something heavy will fall on
[15:03:17] <andypugh> All the original cable conduits are articulated steel.
[15:03:53] <archivist> I hate that steel stuff it comes unscrewed
[15:04:04] <Loetmichel> maybe the kevlar hose is better because its cut resistant but can be flattened withould deformation?
[15:04:28] <Loetmichel> -l
[15:08:12] <andypugh> OK, this isn't a good reason. But I am trying to stay within the design style of the original machine.
[15:09:32] <pcw_home> No hardware store sells flexible conduit by the foot/meter?
[15:10:00] <pcw_home> or electrical supply store
[15:11:42] <pcw_home> plastic or metallic with plastic jacket?
[15:15:31] <andypugh> Not that I have found, no. Certainly not in the sort of size I want (Ideally I want a size I can fit a 9-way D-sub down)
[15:15:45] <pcw_home> I see 1 1/4 Electri-Flex metallic/plastic for $1.71 per foot in the good old USA
[15:20:08] <pcw_home> yeah even here places that sell by the foot are rare
[15:21:41] <andypugh> It's not the sort of thing that anyone who needs it is never going to need more of, in general.
[15:24:29] <andypugh> Farnell sell it by the foot, minimum order quantity 50 feet..
http://uk.farnell.com/hubbell-wiring-devices/b2150/flexible-conduit/dp/2078157
[16:00:36] <pcw_home> that minimum qty kind of makes buying by the foot useless
[16:14:57] <andypugh> I am considering buying
http://www.ebay.co.uk/itm/221047121099 then trying to sell what is left.
[16:16:18] <DJ9DJ> gn8!
[16:17:57] <Tom_itx> andypugh i nearly did the same with my stepper wire
[16:18:13] <Tom_itx> get a 1k roll and peddle 99% of it
[16:35:10] <archivist> I thought the extra should be kept in the "it might me useful" pile :)
[16:35:43] * Jymmm slaps the shit out of andypugh! NO NO NO shoving in the 4ft tall pile! SELL SELL SELL
[16:36:01] <Jymmm> err archivist not andypugh
[16:36:22] <Jymmm> oh hell, andypugh probably deserves to be slapped too for GP
[16:36:30] <archivist> its not me buying extra conduit !
[16:36:37] <Jymmm> =)
[16:36:57] <Jymmm> archivist: Ok, you can slap andypugh too then (and you're closer too)
[16:37:30] <Jymmm> I'd ship my slap to andypugh, but hed probably have to pay VAT on it.
[16:39:16] <Jymmm> Found a local oring mfg that sells individually, cute too =)
[16:39:29] * Tom_itx slaps Jymmm telling him to take one for the team
[16:39:58] <Jymmm> Tom_itx: take what for the team?
[16:40:00] <Loetmichel> hmmm
[16:40:09] <Loetmichel> "there's no I in team!"
[16:40:10] <Loetmichel> ;-)
[16:40:29] <Jymmm> no there there is ME in team!
[16:40:47] <Loetmichel> Jymmm; there is!
[16:40:50] <Tom_itx> and meat
[16:40:56] <Loetmichel> tEaM
[16:41:09] <Jymmm> and ME EAT MEAT too
[16:41:19] <Jymmm> ME ATE MEAT as well
[16:41:55] <Jymmm> ME T[&]A too =)
[16:42:15] <Loetmichel> but like we say "TEAM= Toll ein anderer machts! " ("great, anotherone does it")
[16:42:21] <Loetmichel> + in germany
[16:43:53] <Jymmm> Most orings are EPDM (
http://en.wikipedia.org/wiki/EPDM_rubber) but silicon ones are only pennys higher in price. I can't understand why would someone want EPDM over silicon for roughly the same price?
[16:44:33] <Jymmm> EPDM has a 5year life, Silicon 20 year. I dont get it.
[16:47:13] <Loetmichel> Jymmm: EDPM is a lot harder and more cut-resistant?
[16:47:52] <Jymmm> Loetmichel: In a gasket, I get it. But in an oring?
[16:47:55] <alex4nder> Jymmm: EPDM has better oil resistance
[16:48:05] <archivist> cheaper matters in production
[16:48:16] <Loetmichel> and incorperates less water
[16:48:16] <alex4nder> as an RX-7 owner, I am intimately familiar with oil and silicone.
[16:48:24] <alex4nder> :(
[16:48:36] <Jymmm> alex4nder: and silicon doens't?
[16:48:41] <Loetmichel> Jymmm: especially in an o-ring
[16:48:52] <alex4nder> Jymmm: silicone breaks down
[16:49:04] <alex4nder> but rubber gets hard over time
[16:49:09] <alex4nder> it's why most RX-7 owners go viton
[16:49:29] <Loetmichel> alex4nder: is that the one with the rotating piston?
[16:49:33] <alex4nder> Loetmichel: yup
[16:49:44] <Jymmm> Ew fluoroelastomer, no thanks
[16:49:46] <Loetmichel> and the seals you mean are for the piston?
[16:49:53] <alex4nder> Loetmichel: no, for control systems
[16:49:58] <Loetmichel> ah
[16:50:16] <alex4nder> the seals of the rotor come in many forms, most are steel
[16:50:29] <alex4nder> but there are carbon, ceramic, etc.
[16:52:27] <Loetmichel> help me out: what was the name for a rotating piston engine?
[16:52:38] <Jymmm> rotary engine
[16:52:43] <Loetmichel> hrrmpf
[16:52:48] <Jymmm> lol
[16:53:05] <Loetmichel> i meant the (german) inventor
[16:53:49] <Jymmm> Ford =)
[16:54:22] <Jymmm> Mazda, a division of Ford Motor Company
[16:54:30] <archivist> Wankel
[16:54:40] <Loetmichel> ah, wankel it was, thy
[16:54:53] <Loetmichel> i think my memory is fading :-(
[16:55:12] <Loetmichel> Jymmm: wrong
[16:55:15] <Loetmichel> the bought it
[16:55:47] <Loetmichel> but like a lot of toher engines the inventor was a german
[16:56:05] <Loetmichel> (otto, bosch, benz....)
[16:57:16] <alex4nder> yah, his first inventions were rotary valves
[16:57:25] <alex4nder> for pistol engines' heads.
[16:59:20] <andypugh> Mazda is not a division of the Ford Motor Co. Ford are a minority shareholder in Mazda.
[17:01:22] <Jymmm> wikipedia lies!
[17:02:34] <Loetmichel> what else is new?
[17:02:51] <Jymmm> =)
[17:05:58] <andypugh> Jymmm: Wikipedia says: On November 18, 2010, Ford reduced its stake further to 3%, citing the reduction of ownership would allow greater flexibility to pursue growth in emerging markets. Ford and Mazda remain strategic partners through joint ventures and exchanges of technological information.[12]
[17:06:18] <Jymmm> andypugh: I'm just playing =)
[17:06:35] <Jymmm> andypugh: go look up land rover too
[17:06:41] <Jymmm> and jaguar
[17:07:49] <Jymmm> Heh, I think that was when Ford was going broke.
[17:07:56] <Jymmm> SELL SELL SELL
[17:10:21] <andypugh> Jymmm: Have you forgotten who I work for?
[17:10:44] <Jymmm> andypugh: I dont think I ever knew
[17:10:59] <andypugh> Ford
[17:11:07] <Jymmm> andypugh: Ah
[17:22:21] <skunkworks__> andypugh: cool. did you get to tune the ford gt?
[17:23:50] <andypugh> No, I work on Euro-market diesels.
[17:23:55] <skunkworks__> ah
[17:24:01] <skunkworks__> no gas guzzlers then ;)
[17:24:15] <andypugh> We try not to.
[17:24:20] <skunkworks__> good call
[17:25:30] <alex4nder> andypugh: you guys using the VCM II yet?
[17:25:58] <andypugh> I don't even know what that is
[17:26:13] <alex4nder> it's the new ford vehicle comms box
[17:26:44] <alex4nder> I think they're just about to release it in europe.
[17:27:04] <Nick001-Shop> How do I control 4 different spindles in linuxcnc?
[17:27:20] <andypugh> Ah, no, we use more generic tools because everything is still being written when we start.
[17:27:35] <alex4nder> andypugh: this box just does PDU and J2534
[17:28:00] <alex4nder> cool
[17:28:00] <andypugh> We only use CCP direct to shadow-memory in the PCM.
[17:28:15] <alex4nder> ah, cool
[17:28:27] <alex4nder> so you're doing calibration on pre-production?
[17:28:48] <andypugh> Mainly with:
http://www.accuratetechnologies.com/content/view/178/174/lang,en/
[17:29:42] <andypugh> Yes, I am currently mainly driving around the tracks in a 2013 Mondeo/Fusion.
[17:30:19] <andypugh> http://www.ford.com/cars/fusion/2013/
[17:30:27] <hive8> hi guys
[17:30:37] <alex4nder> nice
[17:30:40] <andypugh> Not a bad looking car, considering it was designed in the US>
[17:30:45] <alex4nder> haha
[17:30:53] <andypugh> Hi hive8
[17:31:12] <Tom_itx> where's the one with the teddy bear on the front? :)
[17:31:54] <andypugh> That's old-hat now, been on sale a few years.
[17:33:57] <skunkworks__> andypugh: sounds like a cool job
[17:34:46] <JT-Shop> hey Sam
[17:34:54] <skunkworks__> hey!
[17:35:20] <skunkworks__> how's the cannon?
[17:35:22] <JT-Shop> I had a crazy idea to take a mack xml file and make my python program create a stepconf file from it
[17:35:22] <Tom_itx> http://www.youtube.com/watch?v=m3KdpzL3Hkk
[17:35:32] <JT-Shop> it goes BOOOOOM
[17:35:37] <skunkworks__> heh
[17:35:49] <joe9> cd /ws 39
[17:36:06] <skunkworks__> I know there was a couple people asking if there was a conversion utility to go from a mach xml to emc
[17:36:41] <skunkworks__> the are supposidly demoing mach 4 at the cnc fest at ann arbor
[17:36:50] <JT-Shop> seems simple enough now, I created a mack xml file and have the python converting to text now
[17:37:03] <skunkworks__> cool
[17:40:36] <gmagno> hello, good evening
[17:41:10] <gmagno> anyone here ever bought something similar to this board (
http://www.ebay.com/itm/3axis-Nema17-stepper-motor-78oz-in-CNC-kit-3A-driver-board-/300654822440) ?
[17:41:19] <gmagno> I'm looking for the driver manual
[17:41:33] <gmagno> since I don't know how to set the dipswitches
[17:42:36] <JT-Shop> did you try and email the contact for more info?
[17:43:15] <andypugh> You can find the datasheet for the driver chip (TB6560) online in many places
[17:43:59] <Tom_itx> JT-Shop did you see my control box so far?
[17:44:12] <JT-Shop> no
[17:44:31] <Tom_itx> http://tom-itx.dyndns.org:81/~webpage/cnc/psu/psu_index.php
[17:44:34] <Tom_itx> last 2 pics
[17:45:19] <andypugh> gmagno: Did it come with a CD? There is probably a manual on that. It is very likely to be the manual for a subtly different baord, though.
[17:45:21] <JT-Shop> ohh blue is my favorite color
[17:45:36] <JT-Shop> nice and neat
[17:45:38] <tjb1> Hey JT-Shop
[17:45:54] <JT-Shop> hey
[17:45:59] <Tom_itx> i still gotta mount the mesa boards and wire all of that in
[17:46:07] <Tom_itx> they're just sitting in there
[17:46:20] <tjb1> Got a quote from T-Slots and they gave me 2 pieces of 116" 3"x3" for $187 compared to 80/20 which was $144 for a 113" piece of 3"x3"
[17:46:25] <tjb1> Plus free shipping
[17:46:58] <JT-Shop> nice score
[17:47:29] <tjb1> Originally quoted me $147 for the 116" piece but I got an email so they must of added an additional student discount
[17:48:05] <andypugh> Tom_itx: You have a woman's capacitors!
https://picasaweb.google.com/lh/photo/HdNJXBD5wPqDUi9E8C46HdMTjNZETYmyPJy0liipFm0?feat=directlink
[17:48:37] <Tom_itx> i got em surplus cheap
[17:48:47] <Tom_itx> they still pack a punch
[17:49:08] <andypugh> I got those for £10 each.
[17:49:18] <gmagno> JT-Shop, yeah, I've already contacted them, but I dont want to wait for it :)
[17:49:21] <gmagno> andypugh, no CD :-/
[17:49:27] <andypugh> (List price £163 each)
[17:50:10] <Tom_itx> and i think you get less ripple with multiple small ones
[17:50:19] <andypugh> gmagno: Well, the driver is the TB6560:
http://www.toshiba.com/taec/components2/Datasheet_Sync/382/27885.pdf
[17:50:42] <andypugh> Tom_itx: Mine are quote small, but that is a 300V supply.
[17:50:44] <tjb1> Is there any use for grooved t-slot extrusion as compared to smooth?
[17:51:38] <Tom_itx> andypugh for your spindle?
[17:52:09] <andypugh> gmagno: From that datasheet you can work out the DIP switch settings, and by tracing tracks you can figure out which opto-isolator goes to which parallel portt pin, and which pin on the TB6560. And that will be a lot more reliable than the manual.
[17:52:17] <andypugh> Tom_itx: No, for my servos.
[17:53:48] <gmagno> andypugh, I think I'm going to do that
[17:53:50] <gmagno> thanks
[17:53:54] <delkin> ora boas
[17:55:11] <andypugh> delkin: ?
[19:31:45] <andypugh> As far as I could make out. delkin popped in, made a random statement in Galacian, and disappered 90 minutes later.
[19:32:24] <andypugh> Ah, no, I missed an inexplicable change in nick.
[19:34:43] <andypugh> By the way, there are two new/unused parker servo drives on eBay at 99p. Could be a bargain to be had there:
http://www.ebay.co.uk/itm/120932197261
[20:36:21] <Tom_itx> andypugh i hate it when that happens
[20:36:59] <andypugh> What?
[20:37:46] <Tom_itx> makes it hard to follow
[20:38:31] <Tom_itx> your nick should be given at birth and follow you your entire life
[20:40:40] <andypugh> But then you would be Tom_Z80
[20:41:10] <Tom_itx> life was much simpler
[20:41:18] <Jymmm> s/z80/abacus/
[20:48:11] <andypugh> I was suddenly overcome by an urge to have one of these:
http://en.wikipedia.org/wiki/Research_Machines_380Z
[20:48:24] <andypugh> But luckily there were none on eBay.
[20:48:53] <andypugh> "High resolution: 320×192 pixels, 2 bits per pixel, 1 page." Ah, those were the days!
[20:49:13] <Jymmm> andypugh if you had an urge to get one of those, please do me a favor and STOP SNIFFING THE DRAIN CLEANER!
[20:50:00] <andypugh> First computer I ever saw, that was. I wasn't allowed to touch it, of course, it was the special province of the chemistry teacher.
[20:50:14] <Jymmm> =)
[20:50:39] <Jymmm> travel 0.5" lol
http://www.ebay.com/itm/Star-Linear-System-Linear-actuator-Slide-w-SMC-Cylinder-/150754938464?pt=LH_DefaultDomain_0&hash=item2319b1ce60
[20:51:10] <Tom_itx> i had a math teacher that felt the same way about his first HP calculator
[20:51:30] <Jymmm> Hell, I STILL feel that way about my HP Calculator =)
[20:51:58] <Tom_itx> with the LED display?
[20:52:16] <Jymmm> http://en.wikipedia.org/wiki/HP-20S
[20:53:16] <andypugh> Jymmm: It's pneumatic. I have no idea what it is for.
[20:54:28] <Jymmm> When I was calibrating laser modules, when had this huge as formula we had to do every day to calibrate the equipment. If was painfully slow on TI Calcs too. I got that, programmed the formula and was damn fast too =)
[20:54:37] <Jymmm> s/as/ass/
[21:00:18] <andypugh> I still use:
http://www.rskey.org/CMS/index.php/7?manufacturer=Casio&model=fx-3400P
[21:01:03] <andypugh> I have long since forgotten how to program it though.
[21:01:49] <andypugh> And the kcal button got ripped off during an over-zealous attempt to clean it. But then I never worked out what that button was for.
[21:02:26] <Jymmm> Tom_itx: Actually, my *VERY* first calculator was given to me and it was LED with a rechargable battery pack.
[21:03:17] <Tom_itx> i still can't find my HS slide rule
[21:03:23] <Tom_itx> used in HS that is
[21:04:21] <andypugh> I never used one. I sometimes wish I knew how.
[21:04:23] <Tom_itx> i'm not sure i'd remember how to use it now
[21:04:52] <andypugh> http://itunes.apple.com/gb/app/slide-rule/id288454455?mt=8
[21:29:07] <andypugh> jthornton: I am looking for the translator guidelines, but can't find any as good as I think I have seen in the past. Any pointers?
[21:29:26] <andypugh> This would be for the spanish chap who jus popped up
[22:01:15] <andypugh> It bothers me when folk buy the wrong hardware after not asking for advice.
[22:01:54] <Tom_itx> not that i need them yet but that's where i'm at with servos and servo controllers
[22:11:29] <andypugh> Well, yes, but I imagine you would ask before getting the card out?
[22:12:04] <Tom_itx> definitely
[22:12:25] <Tom_itx> sometimes you gotta grab stuff when it's there though
[22:12:59] <Jymmm> thats NOT what she said =)
[22:13:18] <Jymmm> (but we wish it was =)
[22:13:25] <Tom_itx> maybe you need to hang with a different crowd :)
[22:14:11] <Tom_itx> naw that's probably true across the board
[22:15:29] <Jymmm> IF you could, would you want to join a commune today?
[22:18:39] <andypugh> I think sserial might be working again. (I have really hacked it about)
[22:19:48] <andypugh> So, that seems like a good time to sleep
[22:20:30] <Tom_itx> i'm about there myself
