[00:07:38] <qrp> lunch back, well you can change your gear ratio or other set, then one pulse means one inch/mm, the counted number is the same as your distance
[00:11:14] <qrp> In our factory condition, 512KHz pulse RS485 , we also loose pulse, so I refuse the 2.5MHz method, maybe you have the better method or better condition; cheap absolute encoder is just my suggestion
[00:12:26] <qrp> I never forced anybody to use the absolute encoder, I just shared the infomation, isn't it very cool
[00:13:08] <pcw_home> Link please
[00:16:15] <qrp> I have made an experiment in my customer factory, I have shared the result, I have told you this is my final solution, we use absolute encoder in spindle motor for high speed and high accuracy
[00:17:17] <pcw_home> link please
[00:20:08] <qrp> ok, ok, I will have a link
[00:21:17] <qrp> but, I still don't think it is a good idea
[00:25:01] <pcw_home> I think a low cost absolute encoder would be great, but most are quite expensive at high resolutions
[00:25:03] <pcw_home> (and the fact that this is not front page news in some tech Journal makes me wonder...)
[00:26:38] <qrp> It's a revolution in my country, many years ago, we even can't imagine it
[00:31:22] <qrp> It's cool, isn't it? the biggest problem is that, you should write a communication agreement for absolute encoder, we use fpga, more difficult to link is the problem
[00:32:46] <pcw_home> Not cool if they are not available (patent issues?)
[00:35:17] <qrp> it's a product, everyone can buy and use it; if you want to handle the tech, I am so sorry...
[00:36:12] <pcw_home> If its a product anyone can buy where do I get it?
[00:37:19] <Jymmm> pcw_home: craigslist
[00:38:17] <qrp> give me a moment, I look for some information for you
[00:38:30] <pcw_home> Thanks!
[00:40:52] <qrp> http://www.alibaba.com/product-gs/740125768/J3806G_0008BM_T5_S_Absolute_encoder.html
[00:41:17] <qrp> it's not the band i use, but you can find more in this website
[00:41:56] <Jymmm> pcw_home:
https://www.sparkfun.com/products/10932
[00:42:01] <Jymmm> pcw_home: $40
[00:42:19] <Jymmm> http://www.rotaryencoder-yumo.com/
[00:44:06] <Jymmm> Interesting, they have touch panels
http://www.yingselectric.com/product.asp
[00:44:58] <qrp> as I know, all the cheap absolute encode use device for Avago, from USA
[00:52:58] <qrp> http://www.avagotech.com/pages/en/motion_control_encoder_products/absolute_encoders/
[00:54:20] <qrp> this is an USA company, I don't know the price, I think you can look for the information and easier to buy
[00:55:05] <qrp> multi turn encoder is much more expensive than single turn, so I suggest you to buy the single turn
[00:56:06] <qrp> mechanic type is more expensive than electronic type, so I suggest you to buy electronic type
[00:56:33] <pcw_home> well its $53 for the head (no wheel shaft or housing) in 2500 qty so
[00:57:32] <pcw_home> not exactly cheap but not terrible if its SSI clock rate is decent
[00:57:44] <qrp> yes terrible
[00:58:15] <qrp> there are many cheap bands in my country
[00:59:14] <qrp> motor with absolute encoder ,we sell add 150$ to relative
[01:12:39] <qrp> avago buy many encoder companys, in Japan and china, including the supplier of FANUC

[04:29:19] <RyanS_> "Digital isn't any more accurate than analog until you've spent thousands on your tool" someone was referring to calipers. Does that sound pretty correct?
[04:29:56] <archivist> depends
[04:30:50] <archivist> always check the calibration and accuracy of your tools
[04:41:44] <RyanS_> hmm regarding micrometres a lot of people seem to be saying vernier is just as accurate as digital, but how can that be if Digital has more resolution so should allow you to take a more accurate readings?
[05:19:57] <jthornton> digital means it is easier to read not that the micrometer is more accurate
[05:27:07] <RyanS_> And because resolution is a different thing to accuracy, you're not going to be able to utilise the higher resolution unless building space telescopes?
[05:30:26] <jthornton> you do have to take gravity into account when building space telescopes it seems
[05:31:34] <Loetmichel> mornin'
[06:32:02] <renihs> why does one get forwarded here when trying to join #emc?
[06:32:24] <JT-Shop> because the EMC corp stole our name
[06:32:38] <JT-Shop> and their lawyers are evil
[06:33:12] <renihs> that doesnt explain the forward to me
[06:34:11] <JT-Shop> for many years we were #emc so the forward is for people who haven't been around in a while
[06:35:01] <JT-Shop> does that explain?
[06:35:21] <renihs> interesting, because i stumbled accross some freenode logs from 2002? where the #emc was an #emc (the evil corporation) channel
[06:36:31] <JT-Shop> I have no clue about the evil corp
[06:36:38] <renihs> so you were emc before that, then emc took the channel (?) with ..lawyers... then you retook the channel and forwarded?
[06:36:56] <renihs> the sequence order of things happening seems unplausible
[06:37:02] <JT-Shop> no, they made us change our name
[06:37:25] <renihs> but allowed a forwarder? :)
[06:37:41] <JT-Shop> don't have a clue and don't care really
[06:38:26] <renihs> well, i guess i wont find some (evil) emc mammal here then who uses this horrible vnx simulator thingie
[06:38:37] <JT-Shop> nope
[08:37:47] <Loetmichel> soo, got the prototype of the 12" tft casing done (made of 2mm styrol) ... seems it works... now make that in aluminium and a backplate and the CNC monitor is done ;-) ->

[09:51:05] <PetefromTn> Mornin' folks....
[10:02:19] <IchGuckLive> hi all after the 4th of juky partytime
[10:02:39] <IchGuckLive> its so nice today in germany and also sunny
[10:03:02] <PetefromTn> Not much of a party here, it rained all day so we only got to fire off a few of our fireworks.
[10:03:35] <IchGuckLive> oh jeah the east is badly hidden by the winter storm
[10:04:00] <IchGuckLive> im off till later
[10:36:14] <Cylly> PetefromTn:
[10:36:28] <Cylly> [15:23] <Loetmichel> soo, got the prototype of the 12" tft casing done (made of 2mm styrol) ... seems it works... now make that in aluminium and a backplate and the CNC monitor is done ;-) ->
http://www.cyrom.org/palbum/main.php?g2_itemId=14310
[10:37:59] <PetefromTn> Loetmichel: nice man... get er done!!
[11:50:43] <qrp> finally, I send my first bug report to the source forge. It cost me two days, because of the internet problem.
[11:52:09] <IchGuckLive> hi all B)
[11:58:02] <IchGuckLive> is psha log down ?
[11:58:41] <Tom_itx> it's still here
[11:58:43] <Tom_itx> dunno
[11:59:01] <IchGuckLive> no log for today or yesterday
[11:59:14] <Tom_itx> zlog works
[11:59:32] <IchGuckLive> B)
[12:01:43] <IchGuckLive> hi Simooon
[12:01:58] <IchGuckLive> denmark still floating above selevel ?
[12:03:55] <Simooon> IchGuckLive, for now ;-)
[12:04:16] <IchGuckLive> ;-)
[12:09:48] <IchGuckLive> Heinz_60: spindel isel running
[12:10:17] <IchGuckLive> did the selfmade comp work out the rpm to 6bit
[12:10:22] <Heinz_60> Not completely
[12:10:42] <Heinz_60> Yeag, your file works great
[12:10:54] <IchGuckLive> SMILE
[12:11:35] <Heinz_60> Now i have my 6 Bits on my mesa Output port
[12:11:49] <IchGuckLive> as expected
[12:12:05] <Heinz_60> Yes
[12:13:33] <IchGuckLive> Not completely means what hint
[12:13:46] <andypugh> qrp: Did you allocate the bug to a specific dev?
[12:14:15] <Heinz_60> Ive set 22volt on field Power
[12:14:35] <IchGuckLive> the optocoplers take up to 22V
[12:14:51] <qrp> no, I did not
[12:14:56] <IchGuckLive> acorrding to datasheet with a resistor in line
[12:15:16] <andypugh> qrp: It doesn't matter, I was just curious.
[12:15:32] <Heinz_60> Which optocouplers?
[12:15:45] <IchGuckLive> of the isel ism200
[12:15:50] <IchGuckLive> 300
[12:16:20] <qrp> a tiny bug, some one suggest me sharing the thinking
[12:16:55] <IchGuckLive> Heinz_60: but better to go for a 2803
[12:17:25] <Heinz_60> 2803?
[12:17:34] <qrp> pwm output , using a RC low pass filter , became analog spindle signal
[12:17:40] <IchGuckLive> or simple finder 81 line relays 5mm width
[12:17:41] <qrp> ULN2803
[12:18:04] <qrp> digital output device?
[12:18:24] <qrp> 1 A current can received?
[12:18:31] <IchGuckLive> qrp: he needs 6bit 22V to 5Vttl
[12:18:38] <Heinz_60> Oh ok. Yeah digital drived spindle
[12:19:31] <Heinz_60> Tomorrow i will measure the current at my calculatet resistors
[12:19:33] <qrp> low current, optocouplers is a good idea
[12:20:04] <IchGuckLive> acording to the datasheed they shoudt be inside the spindel driver
[12:20:31] <qrp> digital signal is easier to isolate, so pwm is a good idea, I think
[12:20:38] <Heinz_60> Ill think there aee still optocouplers inside the ism300
[12:22:32] <qrp> what is ism300?
[12:22:36] <Heinz_60> I wanna check the cables from ism300 to 7i76 but i have no description for the ism300 output field
[12:23:13] <Heinz_60> A very old spindle drivers made by isel
[12:23:40] <qrp> oh, thank you
[12:24:10] <qrp> analog signal usualy don't isolate
[12:24:43] <IchGuckLive> Heinz_60: go for 3,3Kohm and you are fine
[12:25:06] <qrp> so I don't think this is a analog opocoupler in spindle driver
[12:25:20] <Heinz_60> Spannungsteiler?
[12:25:31] <IchGuckLive> qrp: its a very uniq thing
[12:25:40] <IchGuckLive> nein in linie
[12:26:07] <qrp> i like uniq thing
[12:26:25] <Heinz_60> Ok
[12:26:36] <IchGuckLive> he has the full datasheet so he can work throu it
[12:27:43] <andypugh> qrp: The problem probably lies somewhere in one of the zh_ files here:
http://git.linuxcnc.org/gitweb?p=linuxcnc.git;a=tree;f=src/po;h=254d1e0b8299b136a2548ed81688f17941f4b368;hb=refs/heads/v2.5_branch
[12:27:43] <IchGuckLive> dont forget same GND
[12:29:07] <qrp> andypugh : thank you very much
[12:29:18] <IchGuckLive> andypugh: ZH requires ttf-sil-yi installed
[12:29:49] <IchGuckLive> at liest 1.1 better the 1.2
[12:30:27] <IchGuckLive> the ttf-sil-dai or even banna most uses will fail
[12:32:03] <IchGuckLive> therfore hthk always askes for ttf-sil udf-8
[12:32:52] <Heinz_60> Same ground is done
[12:34:06] <IchGuckLive> there is also a MAIN spindel on signal at the serial connector maybe this needs also a on signal
[12:34:29] <IchGuckLive> as the 6bit only desides the rpm
[12:34:31] <Heinz_60> A few days and all is working
[12:35:42] <qrp> #: src/emc/usr_intf/stepconf/stepconf.glade:785 6790 #: src/emc/usr_intf/pncconf/pncconf.glade:326 6791 msgid "" 6792 "Inch\n" 6793 "Millimeter" 6794 msgstr "英制/公制" 6795
[12:35:54] <Heinz_60> Tried a few cables and spindle drives with ttl
[12:36:00] <qrp> these lines of code is the problem
[12:37:06] <qrp> zh_cn.po file
[12:37:33] <IchGuckLive> Heinz_60: E0-E5 Data E7 is also to be High for the direction
[12:37:48] <andypugh> Is the problem stepconf or pncconf?
[12:38:09] <qrp> from the code ,both have the problem
[12:38:14] <Heinz_60> Ok thanks
[12:38:53] <IchGuckLive> qrp: 英制/公制 = Inch/metric the / is the hint
[12:39:26] <qrp> yes ,translate problem,
[12:39:44] <qrp> two lines become one line
[12:40:19] <Jymmm> Literal translation: Inch / Metric
[12:41:37] <qrp> inch means 英制； metric means 公制
[12:43:44] <IchGuckLive> yes all clear but the / is not loaded as the chletters come up
[12:43:56] <andypugh> I think the file must exist somewhere on your systen too
[12:44:27] <andypugh> (I am trying to load up my dev environment to have a play around with the formatting)
[12:47:29] <IchGuckLive> translatable="yes">Inch Millimeter
[12:48:24] <IchGuckLive> so the msg str comand heds of as it reatches the /
[12:48:46] <qrp> msgstr " "
[12:48:57] <qrp> "英制\n"
[12:49:06] <qrp> "公制"
[12:49:49] <qrp> I think this should be the right code in the file zh_cn.po, line 6794
[12:50:46] <IchGuckLive> i woudt go for both without the / as you diont know if its a eng chinese or a metric
[12:50:50] <Jymmm> Oh phuk me, you guys still on that crap. Move on already...

[12:55:08] <Jymmm> Goony goo goo
[12:55:14] <andypugh> Jymmm: The question is what the bug-fix needs to be.
[12:55:26] <IchGuckLive> so the chinise worker knows what the mashine is o n
[12:55:41] <Jymmm> andypugh: Tequila is ALWAYS the answer.
[12:56:21] <andypugh> It's always _an_ answer.
[12:56:31] <Jymmm> heh
[12:56:44] <qrp> you are so kind
[12:59:02] <qrp> i am so sorry, I have to go, thanks for your help
[12:59:36] <qrp> I will try to learn more about the linuxcnc and try to fix the bug
[13:00:06] <IchGuckLive> qrp: your elcome !
[13:00:11] <andypugh> If you add the fix to the bug tracker, that might be best.

[14:05:58] <ktchk> Hi which 4 axis cam is good for linuxcnc ?
[14:15:41] <andypugh> ktchk: A good question. I await answers too.
[14:18:41] <archivist> most cam I have seen either costs a lot or has a limited usage, depends on how much you want to learn to use something
[14:19:36] <archivist> andypugh, should be in London Wednesday, got myself booked into a little archiving conference
[14:20:12] <andypugh> archivist: Where is the conference?
[14:20:23] <archivist> UCL
[14:20:48] <andypugh> I have several friends who work there.
[14:21:04] <archivist> ah :)
[14:21:34] <andypugh> You OK for accommodation?
[14:21:49] <Jymmm> archivist: I thought you did that for personal use, didn't realize it was a hobby for you.
[14:22:46] <andypugh> Good heavens!
http://youtu.be/3IAZJ67HqFs
[14:23:07] <archivist> andypugh, will drive down early am conf is a one day freebee meets at Roberts Building Foyer. have to do something Thursday at 10 am rest is free time
[14:23:53] <archivist> Jymmm, well I do a few online requests now so may as well get known etc
[14:24:32] <Jymmm> archivist: Ah, ok =) I might have to pick your brain on a couple of things sometime.
[14:25:33] <archivist> andypugh, heh big spring, at least I knew what resorts meant (common in clocks)
[14:25:47] <andypugh> If you want to meet up, I am 30 mins away by train. (ish). I have keys for the garage of a 1916 Fire Engine in South Kensington.
[14:27:10] <ktchk> archivist: price range US150 which one works with a postprocessor for linuxcnc?
[14:27:34] <archivist> hmm fire engine.....
[14:27:35] <Jymmm> andypugh: and the keys for the fire engine too?
[14:27:40] <CaptHindsight> I'm picturing you two pulling up to a pub riding in that truck :)
[14:27:46] <archivist> hehe
[14:28:04] <andypugh> archivist: One of my UCL friends had a 14TB datastore in 1998. It's probbaly followed Moore's Law
[14:29:08] <archivist> ew rather large
[14:30:15] <andypugh> Actually, the main use of the Fire Engine is pub crawls, it belongs to a Students' Union
[14:31:19] <Jymmm> lol, love it!!!
[14:32:11] <andypugh> http://www.flickr.com/photos/ashley-brown/499835580/ for example
[14:32:59] <archivist> kick out is about 3:30 I think, I have on recent years used a nice tiny almost unmarked car park near euston
[14:35:38] <andypugh> I have enquired of my local contacts of sneaky carp-arking options.
[14:36:31] <archivist> N Gower St
[14:36:48] <ktchk> bye
[14:36:54] <andypugh> That's rather close anyway, I think
[14:37:37] <archivist> near enough day rate is probably 15 now was 10 when I first went
[14:38:20] <archivist> just north of inner london too and congestion charges
[14:39:08] <andypugh> Ah, yes, I can generally ignore those. I only ride my bike or drive the Fire Engine in London.
[14:39:44] <andypugh> (And back to Jymmm's question) There are no keys, and I am one of the half dozen or so approved drivers.
[14:40:00] <archivist> I save money as best I can, I bet the fuel will be cheaper than train fair too
[14:40:02] <Jymmm> WOOHOO!!!
[14:41:26] <Jymmm> http://www.scienceagogo.com/news/20130604032034data_trunc_sys.shtml
[14:41:36] <archivist> and thinking of arcchives a request has just come in the last few minutes for an Advance SG67A
[14:41:48] <andypugh> archivist: Almost certainly, which is really messed-up
[14:42:31] <archivist> yes silly that a single car and all day parking is cheaper
[17:14:03] <PetefromTn> can't imagine a 90 lb bow and i'm 6' 220...
[17:16:05] <archivist> did you notice the bit about the skeleton changes in the archers :)
[17:29:53] <andypugh> There is a field adjacent to my parents' old house stlll called "Butts" which is where they did their compulsory archery way back when.
[17:34:10] <archivist> bah some sellers should be shot 151061911855 picture not of actual item and every posh name he could think of
[17:39:58] <andypugh> Must be a thing about actors, the "Robert Hardy" mentioned in that Longbow article is the actor.
http://www.imdb.com/name/nm0362735/?ref_=fn_al_nm_1
[17:41:05] <andypugh> He didn't mention "Rivett" :-)
[17:42:50] <andypugh> I might actually "finish" the Harrison this weekend. I have all the parts/castings now.
[17:43:57] <andypugh> Then I find myself wondering what the Chinese Junk is worth. I need the space, and it is one of the most famous horrible lathes in the world :-)
[18:58:17] <JT-Shop> has to be at least worth it's weight at the scrapper
[19:23:58] <andypugh> Sadly my worry is that it might make enough on ebay t make me feel guilty.
[19:30:00] <andypugh> I wish I had seen this 3 days ago!
http://www.ebay.co.uk/itm/HARRISON-M250-CNC-PARTS-AND-MOTOR-/290941411815
[19:32:50] <andypugh> Actually, can anyone see a reason not to BIN and then see what is there?
[19:35:36] <cradek> the price?
[19:36:51] <andypugh> It seems inexpensive for a pair of 2kw drives and the spindle motor. Whatever the servos and other stuff are is then a bonus.
[19:38:02] <andypugh> Annoyingly I just bought a motor (£100) and drive (£60) for the Rivett yesterday.
[19:39:08] <andypugh> Though it was a 700 rpm motor, to be a bit more like line shafting.
[19:52:17] <andypugh> Next step, find the M250 to suit :-)
[19:53:02] <andypugh> Night all
[21:39:10] <Tom_itx> to attach a button for manual tool change indication would i be better off attaching it to iocontrol.0.tool-changed or hal_manualtoolchange.change? both are inputs
[21:50:52] <t12_> does it matter what side of molex connectors you put the male/female pins in?
[21:56:47] <Tom_itx> i would think so
[21:58:21] <Tom_itx> won't they only fit one way?
[22:00:46] <t12> it appears either gender fits in a jack/recepticle
[22:01:03] <t12> plug? jack?
[22:01:08] <t12> whtever they call those genders
[22:03:55] <Tom_itx> which molex connector is it?
[22:03:58] <eric_unterhause1> I was walking across the parking lot at work, some people were wheeling a mendel 3d printer the other direction
[22:04:03] <Tom_itx> molex makes alot of connectors
[22:04:15] <t12> http://www.mouser.com/ProductDetail/Molex/19-09-2048/?qs=LQQHZ4xw2XD7FznDTh6XNg==
[22:04:18] <t12> and mating connectors
[22:05:11] <Tom_itx> the pin should go on the inner part
[22:05:19] <Tom_itx> i would say
[22:06:14] <Tom_itx> although your hdd power connectors are somewhat opposite
[22:06:46] <Tom_itx> i would follow what they do
[22:07:25] <Tom_itx> i can see why they would
[22:08:12] <Tom_itx> the female will center better on the inner connector and you will be able to see any misalignment on the male connector if it's on the outer mating part
[22:09:51] <t12> ah that makes sense
[22:10:02] <t12> basicly female in smaller bore side of connector
[22:10:23] <Tom_itx> that's what hdd power connectors do although they're slightly different
[22:11:24] <t12> wiring up first absurdly built geckdrive + steppers mess
[22:11:43] <Tom_itx> as does the mb power connector
[22:11:53] <Tom_itx> oh i did one of those recently
[22:12:20] <Tom_itx> i used DIN connectors on the steppers
[22:12:29] <t12> i was thinking of 4pin xlr
[22:12:30] <Tom_itx> http://tom-itx.dyndns.org:81/~webpage/cnc/psu/psu_index.php
[22:12:41] <t12> though they seem to be specced for 5A
[22:12:45] <t12> which i guess i could get away with
[22:12:54] <Tom_itx> http://tom-itx.dyndns.org:81/~webpage/cnc/psu/control7.jpg
[22:13:16] <Tom_itx> i like the solid screw connectors better
[22:13:23] <Tom_itx> the original used molex
[22:13:26] <t12> https://www.dropbox.com/sc/g1snssvk4w1hgso/3rKN2nPyFS
[22:13:37] <t12> hum
[22:13:39] <t12> cannot connect
[22:13:40] <t12> for some reason
[22:13:53] <Tom_itx> i can see it
[22:14:05] <Tom_itx> i got the 203v's
[22:14:10] <t12> i mean to yours
[22:14:18] <Tom_itx> port 81
[22:14:21] <t12> yeah
[22:14:26] <Tom_itx> my isp blocks 80
[22:14:27] <t12> maybe work blocks outbound 81 for some reason
[22:14:29] <Tom_itx> bastards
[22:14:50] <t12> yeah can connect from outside work
[22:14:53] <t12> will check when i get home
[22:15:02] <t12> kinda overbuilt the whole thing but thats my tendency
[22:15:06] <Tom_itx> my supply is a bit overkill
[22:15:15] <Tom_itx> but it was all surplus stuff
[22:15:42] <Tom_itx> i've got 3 xfrmrs instead of your 1 :)
[22:15:55] <Tom_itx> all running in parallel
[22:16:17] <Tom_itx> about 48v 18A
[22:16:39] <t12> dang
[22:16:46] <t12> yeah my transformer may actually be underkill
[22:16:48] <t12> but can always swap it out
[22:16:55] <t12> transformers are annoyingly expensive i've discovered
[22:17:03] <Tom_itx> get a toroid
[22:17:03] <t12> but i'll find a good cheap one at in some peice of equipment
[22:17:14] <Tom_itx> i would have, had i not found the surplus ones
[22:18:00] <Tom_itx> what mesa cards are you using?
[22:18:11] <t12> the uh
[22:18:23] <Tom_itx> 5i25?
[22:18:40] <t12> 7I76, 5I25
[22:18:54] <Tom_itx> yeah i can see the 7i76 on the pcb
[22:19:34] <Tom_itx> mine is parport because they didn't have the 5i25 ready yet
[22:19:39] <Tom_itx> 7i43
[22:20:35] <Tom_itx> how big is the diode pack?
[22:21:00] <Tom_itx> i've got one similar but also had some 25A ones so i used one of those
[22:21:11] <Tom_itx> i forget what the black one was, maybe 15A or so
[22:21:29] <t12> http://www.mouser.com/Search/Refine.aspx?Keyword=512-GBPC3510
[22:21:37] <t12> its cool how cheap they are
[22:21:56] <t12> and some tvs diode
[22:22:04] <t12> whole thing is to run at 48v
[22:22:10] <t12> but specced it all up to 80v/7a
[22:22:35] <t12> its actually going on a light duty machine, i just wanted room to have everything in place to move it to something bigger
[22:22:40] <t12> because the cost diff isnt very high
[22:22:48] <Tom_itx> one of my xfmrs looks larger than yours and i've got 3
[22:23:12] <t12> the xfmr is underspecced
[22:23:19] <t12> but i'll likely run everything at 3 or 5a for now
[22:23:21] <Tom_itx> they were marked at 6A
[22:24:10] <Tom_itx> wow you even welded the cap mount
[22:24:20] <t12> hah yeah
[22:24:28] <t12> weldings easier than drill, bolt etc
[22:24:33] <t12> lots of scrap alum around
[22:24:42] <t12> terrible welds though
[22:24:46] <Tom_itx> hope you don't decide to move stuff around
[22:24:52] <t12> hah
[22:24:54] <t12> grinder
[22:25:09] <t12> if i had to grind it all down i'd just prolly build a new one the way i wanted it
[22:25:21] <Tom_itx> i found a nice box online
[22:27:03] <t12> i had the caps lying around from some giant UPS
[22:27:18] <t12> like a crate of those
[22:29:16] <Tom_itx> http://www.newark.com/jsp/search/productdetail.jsp?SKU=01M6871&CMP=KNC-GPLA&mckv=|pcrid|20115734901|plid|
[22:29:34] <Tom_itx> i paid more to ship it than it cost me but still only paid about $45
[22:30:22] <t12> can you just wire parallel transformers... as expected?
[22:30:33] <Tom_itx> if they are exactly the same
[22:30:45] <t12> yeah i gotta figure out a cover for this
[22:30:46] <Tom_itx> i metered the voltage across them
[22:30:54] <Tom_itx> and it was next to nothing
[22:31:12] <Tom_itx> and you gotta get the phases right
[22:32:25] <Tom_itx> i had originally thought of running one per axis with 3 bridges but decided to parallel them instead
[22:32:52] <t12> seems like 1 per would be easier
[22:32:53] <t12> why parallel?
[22:32:55] <Tom_itx> and i used the center tap off one to get me around 24v for my SMPS input for the 5v supply
[22:33:01] <Tom_itx> 48v was too much for it
[22:33:21] <Tom_itx> it was a toss up
[22:34:39] <Tom_itx> i also found about 8' of heatsink material at the local scrap yard
[22:34:53] <Tom_itx> so i mounted the geckos to that
[22:35:04] <Tom_itx> after trimming it down of course
[22:35:14] <Tom_itx> that was a very lucky find

[23:04:43] <CaptHindsight> http://www.viperservo.com/V200.htm anyone ever use these?
[23:06:36] <Tom_itx> t12, kelinginc has toroids as well
[23:07:57] <t12> hum
[23:08:02] <t12> i guess i could always use a variac

[23:08:44] <CaptHindsight> http://www.automationtechnologiesinc.com/products-page/torroidal-power-supplies
[23:08:52] <t12> is there a reason to not use a variac?
[23:08:53] <CaptHindsight> the new Keling ^^
[23:09:24] <Tom_itx> i don't like their new site as well
[23:11:07] <t12> hah i'd have just bought one of those
[23:11:11] <t12> failure to research
[23:11:37] <Tom_itx> me too had i not found surplus
[23:27:12] <RyanS_> These guy is a showoff
http://www.micro-machine-shop.com/mensuration_instruments.htm you can see a picture of a round column milling machine and that pretty much says it all.
[23:31:49] <Tom_itx> he's got a bunch of fancy tools. i wonder if he knows how to use em
[23:33:22] <jdh> cool toys
[23:33:25] <RyanS_> I haven't actually seen any impressive projects he's produced
[23:34:53] <CaptHindsight> how about a single web page that is seven miles long?
[23:35:09] <RyanS_> It's all just tools,
[23:35:29] <Tom_itx> they're all too clean too
[23:36:00] <CaptHindsight> clean tools are a clean desk, how much work is he actually doing?
[23:36:43] <Tom_itx> i could show a similar equipped shop that _is_ used
[23:36:53] <CaptHindsight> the same rule does not apply to car interiors or bathrooms
[23:38:02] <RyanS_> I don't think even professional workshops have that much measurement stuff?
[23:39:16] <Tom_itx> http://www.users.qwest.net/~kmaxon/page/side/mill12_137.htm
[23:39:24] <Tom_itx> another similar
[23:39:50] <RyanS_> ooo, he made some brackets, genius
[23:40:06] <Tom_itx> that guy gets stuff done
[23:40:14] <Tom_itx> you should look around his site
[23:42:25] <Tom_itx> http://www.users.qwest.net/~kmaxon/page/side/mill100_137.htm
[23:42:47] <RyanS_> I've hired some help to tinker in the shed/workshop ( due to my disability), six hours a week you would think was an okay amount,but time gets used up pretty quickly
[23:44:41] <RyanS_> Most of it isn't my stuff so I spend too much time hunting for mixed up drill bits
[23:45:35] <RyanS_> At least that guy has the milling machine and lathe to match the expenditure on measurement staff
[23:45:47] <RyanS_> stuff
[23:46:23] <Tom_itx> one project was an injection mold machine
