[00:09:15] <JT-Shop> I rode my wing to Key West this summer pulling my Can Am trailer 3100 miles round trip
[00:09:25] <LeelooMinai> I wonder if I should attach some box with buttons to the front of my cnc.
[00:09:29] <PetefromTn_> how come you did not ride your can am?
[00:09:38] <LeelooMinai> Some kind of "oh shit" button maybe?
[00:10:31] <malcom2073> LeelooMinai: Like an estop?
[00:10:45] <PetefromTn_> no man Oh-Shit!!
[00:10:54] <PetefromTn_> ;)
[00:10:58] <malcom2073> Heh
[00:11:07] <malcom2073> Typically yelled anyway when scrambling for the estop button :P
[00:11:15] <LeelooMinai> Yes, something other that is common to put there?
[00:11:58] <LeelooMinai> Because if I have to attach some box there, I can as well add other switches, controls, or whatever.
[00:12:39] <JT-Shop> PetefromTn_, the wing is more comfortable and actually handles better and has better brakes
[00:14:02] <shaun414> you guys flying?
[00:14:03] <LeelooMinai> Or I could just attach one button like this: http://www.aliexpress.com/item/SHANDE-QUALITY-emergency-stop-push-button-switch-e-stop-with-NC-silver-alloy-contact/879299937.html
[00:14:17] <shaun414> flying away?
[00:14:17] -!- ttuner has quit [Ping timeout: 272 seconds]
[00:16:09] <PetefromTn_> I am sure.. I rode a wing once and it was both comforatble and surprisingly quick.
[00:18:07] -!- shaun414 has quit [Quit: Leaving]
[00:18:21] <JT-Shop> they really handle well for a 900 lb bike
[00:18:30] <JT-Shop> and get 45 MPG
[00:19:18] -!- tocka has quit [Quit: My MacBook Pro has gone to sleep. ZZZzzz…]
[00:19:50] <JT-Shop> PetefromTn_, you ever listen to Leon Redbone?

[00:24:49] <JT-Shop> I wonder what the Pink Floyd album will sound like
[00:26:26] <PetefromTn_> apparently it is made up of some of the music they recorded for the Division Bell album and had music from Richard Wright before he died. It is called Endless River
[00:27:58] <JT-Shop> just listening to it now on putube
[00:28:45] <PetefromTn_> If it is anything like Division Bell I will have to own it.
[00:30:01] <JT-Shop> I've not heard Division Bell
[00:30:21] <JT-Shop> I don't think I've bought an album in 20 years LOL
[00:30:50] <JT-Shop> If it is anything like the wall I will like it
[00:31:19] <PetefromTn_> The Endless River broke the record for the most pre-ordered album in Amazon UK's history
[00:31:43] <ssi> it won't be anything like the wall
[00:31:45] <PetefromTn_> it is honestly not that much like the wall... It is better in my view
[00:31:58] <PetefromTn_> it is more laid back and peaceful somehow
[00:32:24] <PetefromTn_> I must have listened to it a thousand times now since we bought it.
[00:32:48] <JT-Shop> I'll have to get it and listen to it
[00:33:06] <CaptHindsight> The Wall is 35 years old in two weeks
[00:33:30] <PetefromTn_> it's funny I went upstairs earlier to check on my wife and she had it on our studio monitor speakers in our bedroom while she was folding clothes...
[00:33:31] <ssi> is that all?
[00:33:49] <CaptHindsight> http://en.wikipedia.org/wiki/The_Wall
[00:34:18] <PetefromTn_> I loved the Delicate Sound of Thunder too.... On the turning away was very nice.

[00:35:19] <JT-Shop> I used to listen to the wall on my Sony Walkman while flying back and forth to Africa every month... really made the flights better
[00:35:23] <PetefromTn_> My wife and I were talking about this earlier, I wonder.....when they are no longer able to or willing to make music. what artists today will be the ones who make music LIKE not necessarily the same as Pink Floyd?
[00:36:01] <PetefromTn_> I mean the kind of mellow music that you can enjoy for hours and hours...
[00:36:31] <JT-Shop> I can't even understand music from this decade
[00:36:47] <JT-Shop> it all just seems like noise or rap
[00:37:19] <ssi> JT-Shop: you sound SO OLD right now ;)
[00:37:21] <PetefromTn_> I am not saying that there are NOT musicians today who have the same magic but just who exactly would be similar that is worth listening to?
[00:37:39] <zeeshan> JT-Shop: whyd you go to africa
[00:37:54] <JT-Shop> I worked on an oil rig
[00:38:00] <zeeshan> ah cool
[00:38:05] <JT-Shop> ssi, I am old
[00:38:15] * ssi carefully gets off JT's lawn
[00:38:31] <JT-Shop> I've been riding motorcycles since '68
[00:39:04] <JT-Shop> no worries it's too cold to drag the cannon out
[00:39:10] <CaptHindsight> I was really surprised to see rap/hip-hop last so long
[00:40:15] <SpeedEvil> https://www.youtube.com/watch?v=CeATvJpBpe4
[00:40:37] <SpeedEvil> hmm - that's notthe mix i was thinking of
[00:40:39] <_methods> yea it doesn't seem to be going away lol
[00:40:42] <PetefromTn_> Hey man I saw Florence and the Machine open for U2...
[00:40:49] <PetefromTn_> she is actually pretty good
[00:41:02] <CaptHindsight> she has an amazing voice
[00:41:16] <PetefromTn_> She wore a long flowing dress and ran around that MASSIVE stage barefoot the whole time
[00:41:25] <JT-Shop> sweet
[00:41:28] <SpeedEvil> Top 40 is in many cases simply lack of imagination.

[00:42:32] <PetefromTn_> ain't that the truth.

[00:44:07] * JT-Shop heads inside
[00:44:43] <CaptHindsight> Led Zeppelin has been in the press a lot lately
[00:45:01] -!- moorbo has quit [Remote host closed the connection]
[00:45:05] <CaptHindsight> after being quiet for so long
[00:46:01] <SpeedEvil> That's not always a good thing.
[00:46:06] <SpeedEvil> Gary Glitter, for example.
[00:46:46] <ssi> lol
[00:47:39] <CaptHindsight> Led Zeppelin Loses First Round in ‘Stairway to Heaven’ Lawsuit
[00:48:12] <PetefromTn_> https://www.youtube.com/watch?v=Eh8eAOiccxs LOL this is the ACTUAL concert we saw on the same night so we were somewhere in the audience about six rows back behind the stage
[00:49:03] <CaptHindsight> how was the audio?
[00:49:11] <PetefromTn_> LOUD!!!
[00:49:14] <PetefromTn_> heh
[00:49:32] <CaptHindsight> outdoor venues tend to be better than indoor the past 30 years
[00:49:40] <PetefromTn_> cellphones always get drowned at live concerts.
[00:50:24] <CaptHindsight> heh, I would have left after Florence was over
[00:50:59] <PetefromTn_> then you would have missed the best part :P
[00:51:19] <CaptHindsight> U2 pre 1990?
[00:51:34] <renesis> capthindsight: line arrays ftw
[00:51:57] <renesis> also better low frequency efficiency
[00:52:41] <renesis> also, fuuuuuu @ stairway lawsuit
[00:52:45] <CaptHindsight> I stopped going to live venues when all they could do was turn it up to 11
[00:52:52] <CaptHindsight> rock venues anyway
[00:53:10] <renesis> i think big problem is two way speakers and metal compression drivers
[00:53:30] <renesis> like, they have to cross them low because the 12" and 15" drivers in two way break up horrible in the mids
[00:53:32] <CaptHindsight> big bands and orchestras can never be too loud
[00:53:42] <renesis> so the compression drivers are run at resonance
[00:53:47] <renesis> the ring, horribly
[00:54:00] <renesis> and accordian or violin will make them scream
[00:54:29] <CaptHindsight> https://www.youtube.com/watch?v=xBlQZyTF_LY wish I could have been there 10000 singing Beethoven - Ode an die Freude
[00:54:29] <renesis> also harmonica
[00:54:31] <PetefromTn_> https://www.youtube.com/watch?v=79RNW_ZERn8
[00:54:37] <PetefromTn_> Cool live from that night!!
[00:55:06] <renesis> that sounds pretty good
[00:55:34] <CaptHindsight> EL and LED's in his jacket
[00:55:53] <PetefromTn_> honestly I have seen a bunch of live concerts over the years but that was a great night. It was hot as hades there tho..

[00:59:34] <renesis> petefromtn_: co2 jets are great for the heat
[01:00:03] <renesis> before music box shut down and was turned back into the fonda theater, they had bunch of co2 jets installed on the front edge of the balcony
[01:00:17] <CaptHindsight> do the sound engineers understand what distortion is?
[01:00:29] <renesis> maybe 2 or three times a show, they would blast the audience on the floor with the co2, felt like cold win, was great
[01:00:31] <CaptHindsight> and why you want to avoid it
[01:00:40] <renesis> depends on sound engineers
[01:00:50] -!- Nick001-shop has quit [Quit: ChatZilla 0.9.91 [Firefox 30.0/20140605174243]]
[01:00:55] <renesis> also they often have little or no input into how the sound system was installed and setup
[01:02:19] <PetefromTn_> that sure would have made it nicer. The place was PACKED and the more people came in and the more they tried to push towards the stage the hotter it got. It got really bad but once the sun went down and the heat kinda moved off U2 came out and it was awesome after that.
[01:02:44] <renesis> ive only seen it done there
[01:03:14] <renesis> the heat thing happens every big show ive been to with standing room areas
[01:03:15] <CaptHindsight> why I would only go to the Auditorium Theater, Alpine Valley, Red Rocks etc etc
[01:03:32] <renesis> i want to go to red rocks
[01:03:38] <PetefromTn_> I love red rocks..
[01:03:41] <PetefromTn_> been there once
[01:03:49] <renesis> low ends gotta be so tight
[01:03:49] <PetefromTn_> what a beautiful natural amphitheatre

[01:09:10] <PetefromTn_> yeah it was unbelievably massive... pictures do it no justice.

[01:10:25] <CaptHindsight> I wonder of going back to see Pink Floyd in the 70's for the Animals tour would be the same
[01:10:40] <PetefromTn_> I would LOVE to see that...
[01:10:45] <PetefromTn_> at any time really.

[01:22:03] <PetefromTn_> except for a flight stopover and I never left the airport ;)

[01:25:51] <CaptHindsight> I've heard of it
[01:26:39] <CaptHindsight> Grand Ole Opry House is another
[01:28:11] <PetefromTn_> yeah I am honestly not much for country music but I hear it is a nice place
[01:28:30] <CaptHindsight> me to, I'd like to at least see them

[01:46:15] <CaptHindsight> matador_2k: new project?
[01:50:19] <LeelooMinai> I must to come up with some reasonable idea for the table for my CNC 21" by 21" or so
[01:50:38] <LeelooMinai> Without going bankrupt that is
[01:51:12] <LeelooMinai> Something that will allow me to clamp/fix aluminum pieces
[01:51:26] -!- nofxx_ has quit [Remote host closed the connection]
[01:51:29] <CaptHindsight> t-slot table maybe?
[01:51:50] <zeeshan> LeelooMinai: buy a piece of plate
[01:51:55] <zeeshan> and just drill holes in it with your cnc
[01:51:56] <zeeshan> :P
[01:52:30] <LeelooMinai> WOuld be nice - I would buy a fixung det for t-slot table, but, the problem is getting it for reasonable price.
[01:52:37] <LeelooMinai> fixing set*
[01:52:59] <CaptHindsight> I see them on ebay
[01:53:22] <LeelooMinai> You mean those that look like made from extrusions?
[01:53:23] <CaptHindsight> few hundered $
[01:53:27] -!- Valduare has quit [Quit: Valduare]
[01:53:40] <CaptHindsight> steel t-slot tables/plates
[01:54:19] <LeelooMinai> Are those usually, well, flat? :)
[01:55:50] <LeelooMinai> NOt sure if they are made to be super-flat like surface plates, or just "reasonably flat"
[01:59:08] <CaptHindsight> also fixture plates
[01:59:37] <CaptHindsight> look for a steel one, get it ground to perfection
[02:00:14] <PetefromTn_> not sure he is even talking about a mill table really. Could be just wanting to build a 21x21 router...
[02:00:28] -!- lucashodge has quit [Client Quit]
[02:00:50] <jdh> 0.5" mic6 plate?
[02:01:36] <LeelooMinai> I am "she", and I already built my cnc - I just need plate that will go on top of my bed that will be flat and allow fixing stuff.
[02:01:55] <LeelooMinai> No, mic6 is not reasonable price-wise:)
[02:02:20] <PetefromTn_> Oh sorry I thought we were answering matador dude's post LOL
[02:02:38] <PetefromTn_> look for cast tooling plate.
[02:02:45] <PetefromTn_> it is cheaper and somewhat flat
[02:02:52] <_methods> you just want a sub plate?
[02:03:00] <_methods> bolt something down and mill it flat
[02:03:10] <PetefromTn_> is this a router or mill?
[02:03:31] <LeelooMinai> It's supposed to be able to mill aluminum
[02:03:42] <jdh> my router can mill aluminum
[02:04:03] <LeelooMinai> I mean mill without deforming itself into precel:)
[02:04:05] <CaptHindsight> get a hunk of plate and have someone grind it
[02:04:05] <PetefromTn_> yeah I know but it is amazing how easily people toss the two names around CNC router and CNC mill...
[02:05:03] <PetefromTn_> basically every weak built from toothpics and bailing wire cnc with a little router head mounted to it is a CNC mill nowadays somehow.
[02:05:29] <CaptHindsight> don't forget magnets
[02:05:37] <PetefromTn_> oh sorry :0
[02:05:37] <_methods> or pipes
[02:05:45] <CaptHindsight> lol
[02:05:50] <CaptHindsight> don't remind me
[02:06:23] <PetefromTn_> what really bugs me is when I search ebay or youtube for CNC mill stuff I have to wade thru the gajillion or so CNC router ads and builds touted as CNC mill
[02:06:29] <LeelooMinai> I designed mine to be able to mill small alimunum pieces - nothing extreme. It also has to be in my room - I cannot put there some 2 ton monster, you know:)\
[02:06:58] <PetefromTn_> oh I am fine with routing aluminum on a stoutly build CNC router...
[02:07:12] <PetefromTn_> just kinda wish they would call it that.
[02:07:35] <PetefromTn_> There are quite a few youtube videos showing little sturdy build CNC routers cutting aluminum quite well.
[02:07:42] <LeelooMinai> Well, so how would you call something that can mill aluminum?
[02:08:05] <PetefromTn_> depends....is it a CNC router table or a CNC milling machine?
[02:08:24] <LeelooMinai> Now I don't know - you tell me:)
[02:08:31] <PetefromTn_> LOL
[02:08:38] <PetefromTn_> post a pic..
[02:08:41] <LeelooMinai> I thought if it mills, then it's mill
[02:08:57] <LeelooMinai> But I just call it "cnc platform" for myself
[02:09:04] <PetefromTn_> I like that...
[02:09:11] <CaptHindsight> http://www.instructables.com/id/Simple-CNC-Machine/
[02:09:23] <PetefromTn_> CNC Platform capable of kicking ass is soft aluminum like materials and wood and plastics
[02:09:30] <LeelooMinai> I think I already linked it once here. Here's some old pic of it: https://www.flickr.com/photos/100017731@N03/14362017434/
[02:09:59] <jdh> looks like a gantry router
[02:10:05] <PetefromTn_> I'd personally call that a very sturdy built CNC gantry router.
[02:10:15] <jdh> but, it doesn't really matter what you call it.
[02:10:29] <renesis> its in between
[02:10:34] <CaptHindsight> henry
[02:10:40] <renesis> table moves so not a pure gantry router
[02:11:07] <renesis> also jezus fuck thats a lot of aluminum plate
[02:11:38] <LeelooMinai> You see it has this small "table" there, that is just a bed fixed to all the blocks - I always planned to put some thicker plate on it - that what I was asking about.
[02:11:52] <PetefromTn_> https://www.flickr.com/photos/100017731@N03/14039474097/in/photostream/ CNC hobby router ;)
[02:12:08] <LeelooMinai> Yes, well, I wanted it to be stiff, so I can mill that aluminum.
[02:12:14] <_methods> hahahhah
[02:12:19] <_methods> is that 1" alum?
[02:12:23] <_methods> had to cost a fortune
[02:13:01] <_methods> that's a beefy gantry you should have no problems cuttin some alum
[02:13:04] <LeelooMinai> lol, ok, that catapult I made, because one day my nephew come to my house and said "Aunty, I need to build a catapult for my project - it's for tomorrow, or I will get F":)
[02:13:09] <renesis> fell off the back of the aluminum truck
[02:13:10] <PetefromTn_> jeez Leeloo looking thru your pics you have been a busy girl LOL
[02:13:44] <LeelooMinai> NOte that the catapult has a wooden spoon part I stole from my mom's kitchen
[02:14:26] <LeelooMinai> Yes, I do a lot of hobby stuff - programming, electronics, and now this CNC stuff
[02:14:37] <jdh> henry the fixed gantry router that cuts aluminium
[02:14:47] <LeelooMinai> But CNC part foes slow, since it's not cheap to get all the parts

[02:15:32] <LeelooMinai> The gantry parts were about $70 each - nothing crazy really
[02:15:40] <zeeshan> why do you guys make machine tools out of aluminum
[02:15:46] <zeeshan> you need so much more of it
[02:16:09] <PetefromTn_> that thing looks very well put together LeeLoo
[02:16:18] <LeelooMinai> zeeshan: I have some steel angles there, but in general, in my case, I had to use aluminum, because I could not machine steel at home
[02:16:31] <zeeshan> LeelooMinai: i know your case
[02:16:34] <LeelooMinai> All I have is drill press:)
[02:16:35] <zeeshan> im mainly picking on CaptHindsight

[02:17:01] <zeeshan> CaptHindsight: its still aluminum
[02:17:03] <zeeshan> why aluminum
[02:17:04] <LeelooMinai> And I cannot weld... and do not want to really
[02:17:09] <zeeshan> 70 gpa vs 200 gpa

[02:35:35] <zeeshan> that cable is like 12 feet or something
[02:35:39] <zeeshan> ok nm
[02:35:43] <zeeshan> its like 6 feet
[02:35:47] <PetefromTn_> I would ask PCW if there is any advantage between the two cable types.
[02:35:57] <zeeshan> well he said that flat is no good for noise
[02:36:01] <zeeshan> but for short distances, it might be ok
[02:36:10] <zeeshan> i dont know what "short" is
[02:36:11] <zeeshan> :P
[02:36:23] <jdh> wrap it in aluminum foil and use inline resistors
[02:36:27] <PetefromTn_> I would probably use the parallel style if it is better for noise..
[02:36:44] <zeeshan> can you buy a 2 foot parallel style cable?

[02:54:58] <zeeshan> The Xilinx FPGA on the 5I25 has the option of havin g weak pull-ups on all I/O pins at power-up or reset. The default is to disable the pull-ups To enable the built-in pull-ups, (the default condition) jumper W4 should be placed in the UP position. To disable the internal pull-ups, W4 should be in the DOWN positio n.
[02:55:01] <zeeshan> can someone make sense of this
[02:55:03] <PetefromTn_> usually when I needed to turn a shaft that did not fit thru the spindle
[02:55:07] <zeeshan> "What is the default"
[02:55:19] <zeeshan> theres 2 defaults in that statement

[03:05:18] <zeeshan> if w1 is set to left on the 7i77
[03:05:23] <zeeshan> do i only need to provide power to vin
[03:05:25] <tjtr33> 6 v wheels on a single truck? isnt that impossibly over-constrained?
[03:05:35] <zeeshan> and all the fields will also get power
[03:05:40] <PetefromTn_> over constrained...I love that.
[03:05:42] <zeeshan> or still need to jumper the field powers?
[03:05:43] <zeeshan> from the vin
[03:05:59] <LeelooMinai> ON 7i76 they are shorted
[03:06:06] <zeeshan> ok
[03:06:08] <zeeshan> should be same for me then
[03:06:12] <zeeshan> so you only power vin right?
[03:06:18] <LeelooMinai> You can just check with multimeter:)
[03:06:19] <zeeshan> not the vfields
[03:06:29] <zeeshan> i still need to replace my multimeter
[03:06:31] <zeeshan> my friend blew it up
[03:06:39] <zeeshan> :-(
[03:06:43] <Shaun413> your fiend blew up?
[03:06:45] <Shaun413> may he rip
[03:06:47] <jdh> "my friend"
[03:06:57] <Shaun413> get a fluke man!
[03:07:01] <Shaun413> it wont blow up
[03:07:01] <LeelooMinai> There's a jumper for vin vs the 4 field ones, but the 4 field ones are connected
[03:07:06] <zeeshan> jdh he decided to measure the current of the radiator fans with it
[03:07:11] <zeeshan> in non fused mode
[03:07:14] <Shaun413> wow
[03:07:15] <Shaun413> idiot
[03:07:21] <CaptHindsight> didn't you guys already pick on him last week for this?
[03:07:32] <LeelooMinai> So 5 pins, but one is used to power the actual ics that handle field io
[03:07:37] <PetefromTn_> http://knoxville.craigslist.org/tls/4718764042.html I need this...
[03:08:10] <zeeshan> i should re-read the sentence
[03:08:13] <zeeshan> it clearly states it
[03:08:22] <zeeshan> "This connects field power to vin"
[03:08:23] <zeeshan> :)
[03:09:27] <LeelooMinai> zeeshan: Concentrate and do not burn your nice mesa hardware:)

[03:10:57] <Shaun413> nope no wires
[03:11:13] <PetefromTn_> I shorted out the DC24v power supply wire to a 220v hot lead accidentally
[03:11:30] <PetefromTn_> it ran back thru the power supply and fried the field I/O section of the 7i77
[03:11:42] <zeeshan> doh
[03:11:49] <zeeshan> were there sparks
[03:11:55] <PetefromTn_> yeah I think I can still see em'
[03:11:58] <zeeshan> ahaha
[03:12:34] <zeeshan> so far the only thing i see that can blow stuff up in config is
[03:12:41] <zeeshan> is if w5 is in left position
[03:12:47] <zeeshan> and you try to power tb1
[03:13:04] <zeeshan> the voltage travels to the 5i25 and burns it and possibly mobo
[03:13:20] <PetefromTn_> the good news is it somehow saved my 5i25 and my PC during the fireworks...
[03:13:29] <Shaun413> are there well made mini machine tools?
[03:13:33] <Shaun413> do they exist?
[03:13:33] <zeeshan> field is isolated!
[03:13:35] <zeeshan> it did its job :)
[03:13:41] <PetefromTn_> shaun314
[03:13:43] <PetefromTn_> yeah
[03:13:49] <Shaun413> ?
[03:13:50] <PetefromTn_> there are actually quite a few
[03:13:57] <PetefromTn_> but they are not usually cheap
[03:14:02] <Shaun413> ahh
[03:14:04] <Shaun413> well thats needed
[03:14:05] <Shaun413> :p
[03:14:08] <PetefromTn_> it depends on what you want to cut and how big it is
[03:14:20] <Shaun413> thats the whole reason of going mini, would be cost
[03:14:26] <LeelooMinai> Shaun413: Mini mill:) http://pics.stampedeproject.com/Proxxon-MF70/
[03:14:42] <PetefromTn_> mini does not necessarily mean cheaper
[03:14:57] <Shaun413> hmm
[03:14:58] <LeelooMinai> It's $500 or so I think
[03:15:28] <jdh> we have one of those at work, they are kind of cool

[03:19:33] <zeeshan> but the 7i77 comes default as "provide me with power from 5i25"
[03:19:36] <zeeshan> :P
[03:19:48] <zeeshan> LeelooMinai: did you notice that
[03:19:50] <zeeshan> with your case?
[03:20:11] <LeelooMinai> zeeshan: Don't remember - I just set it up to use 5V from 5i25
[03:20:23] <zeeshan> mines 5v from external

[03:28:16] <zeeshan> i wonder why the y have like 8 of the same size drill chuck
[03:29:08] <PetefromTn_> throw it out at my house.
[03:29:48] <LeelooMinai> I wonder if some machinist gods would strike me from heavens if I bought that plate and made holes in it

[03:30:01] <zeeshan> with threaded inserts
[03:30:22] <LeelooMinai> Hmm
[03:30:37] <zeeshan> our inspection plates
[03:30:42] <zeeshan> in the factory were drilled

[03:31:28] <zeeshan> only pic i can find :P
[03:31:29] <PetefromTn_> weight might be a factor in how your machine performs
[03:31:47] <zeeshan> i agree with PetefromTn_
[03:31:57] <zeeshan> why had a 100lb chunk of granite table
[03:32:00] <LeelooMinai> RIght, I calculated it once and it scared me
[03:32:02] <zeeshan> and deflect your matchine for no reason

[13:13:16] <Loetmichel> *ha!* it fits like a glove!... but that keyboard is VERY expensinve now... the CNC had taken the better part of 5 hours to mill that aluminium part... ;-)) -> http://www.cyrom.org/palbum/main.php?g2_itemId=15386
[13:16:34] * SpeedEvil wonders how to make an entirely optical keyboard cheap
[13:16:50] <SpeedEvil> (apart from a small electronics module with one USB wire to it)
[13:17:20] <malcom2073> SpeedEvil: like beam breaking?
[13:17:27] <SpeedEvil> yes
[13:17:42] <malcom2073> Or this: http://i.imgur.com/EyLrY.jpg?3
[13:17:43] * SpeedEvil wonders about a partially routed PCB, with fibres pressed in
[13:17:51] <SpeedEvil> Those are crap
[13:17:58] <malcom2073> I'd imagine so heh
[13:18:02] <SpeedEvil> no crapper feel than touchscreens of course
[13:18:07] <malcom2073> I can't see how they're easy to use for anything but hunt and peck
[13:18:19] <malcom2073> s/easy/good
[13:19:26] <malcom2073> What about using color? Each key has its own light color, and detect the incoming color as a combonation of colors? Like a resistance based keypad, but optical
[13:19:54] <SpeedEvil> malcom2073: you can
[13:20:03] <SpeedEvil> malcom2073: for example - I can hit ~30wpm on a nexus 7
[13:20:06] <SpeedEvil> without looking
[13:20:16] <malcom2073> Oh I enjoy touchscreen keyboards
[13:20:28] <malcom2073> not as much as a normal one, but they're not bad to use if it's a decent screen
[13:20:30] <SpeedEvil> but - I can hit 40wpm on my n900 - with an actual hardware keyboard and 100% confidence that what I've typed is real, not garbage
[13:21:00] <SpeedEvil> to the point I'd type paragraphs while doing other things

[19:34:23] <yeahsup> hey, I have question about the power supply of the CNC I am currently building. I've got 4 stepper motors (bipolar, 2.8V, 1,7A). Is a 200W 24V powre supply enough? (I calculated 2phases * 2.8V * 1,7A ~ 10W per motor, with some loss in the driver at worst 20W => 80W total). is my calculation correct?
[19:38:51] <cradek> do your drives limit you to 24v?
[19:39:15] <cradek> I don't know the answer to how much power is enough, but I know you absolutely want as much voltage as possible

[20:27:58] <SpeedEvil> yeahsup: if you actually run 2.8V steppers at 2.8V, you will get very, very slow speeds.
[20:28:19] -!- karavanjo has quit [Quit: karavanjo]
[20:28:20] <SpeedEvil> They typically are run at 1.7A - constant current - from a drive that can do higher voltage
[20:28:37] <yeahsup> sorry for the late response, I've got those motors http://shop.myhobby-cnc.de/media/pdf/nema17.pdf
[20:28:39] <yeahsup> last one in the list
[20:28:54] <SpeedEvil> if you run them at 28, not 2.8V - current limited to 1.7A - you get 10* theRPM, and the same torque
[20:28:58] <yeahsup> my power supply is a meanwell 200W 24
[20:28:59] <yeahsup> V
[20:29:21] <yeahsup> using big easy drivers
[20:29:36] <SpeedEvil> not familiar with those
[20:30:35] <yeahsup> can take 2,0A per phase and upto 30V
[20:31:47] <yeahsup> so I guess my driver gets 24V and transforms this to 1,7A (whatever current I adjust it to) and the motor takes its 2,8V?
[20:32:24] -!- karavanjo has quit [Client Quit]
[20:34:07] <ssi> it doesn't transform anything
[20:34:23] <ssi> the coils are inductive, so it takes time to saturate them
[20:34:28] <ssi> the more voltage, the quicker they saturate
[20:36:05] <renesis> motors are magnetic, so their force is proportional to current through them, not voltage across them
[20:36:37] <renesis> so if you want lots of current through a coil quickly, you need lots of voltage
[20:38:22] <yeahsup> hm =/ soooo I still don't get it. 24V/200W power supply, 4 of those motors from the spec set to 1,7A. will this work?
[20:38:56] <renesis> not enough information
[20:39:05] -!- capricorn_1 has quit [Read error: Connection reset by peer]
[20:39:14] <yeahsup> what is missing?
[20:39:46] <renesis> inductance and resistance of the motor coil i guess
[20:40:51] <renesis> anyway, the driver prob wont regulate the voltage to a lower voltage, its going to chop up the voltage and look at the current
[20:41:19] -!- capricorn_1 [capricorn_1!~raffi@zima.linwin.com] has joined #linuxcnc
[20:41:33] <yeahsup> according to the spec its 2.8 mH (whatever unit this is) inductance, and 1.65 Ohm / Phase resistance
[20:42:12] <renesis> millihenries
[20:43:02] <renesis> so now you prob want to look in the manual for your driver
[20:43:20] <ssi> 2.8mH wants around 50V iirc
[20:43:22] <renesis> and see what it recommends
[20:44:06] <Tom_itx> sounds about right
[20:44:08] <ssi> 1000 * sqrt(0.0028H)
[20:44:11] <ssi> = 53V

[20:44:39] <Tom_itx> what happens if you exceed that?
[20:44:53] <bnmorgan> you may let the magic smoke out.
[20:45:01] <Tom_itx> maintaining constant current...
[20:45:13] <ssi> I think that's just the voltage where anything higher is diminishing returns
[20:45:29] <ssi> that's the "coil saturates fast enough" voltage
[20:45:30] <Tom_itx> kinda what i thought
[20:45:39] <Tom_itx> yeah
[20:45:50] <ssi> and i think above that voltage you'll get excessive heating
[20:46:02] <Tom_itx> probably
[20:46:11] <Tom_itx> mine run very cool for steppers
[20:46:29] <Shaun413> hi
[20:46:37] <Tom_itx> but i don't have em cranked up all the way either
[20:47:53] <yeahsup> is there any formula I can plug in my numbers to get a matching power supply? (sorry for being too dumb somehow -.- )
[20:48:10] <ssi> yeahsup: I gave it to you above
[20:48:14] <Tom_itx> sure
[20:48:15] <ssi> 53V is the magic number
[20:48:22] <renesis> there are usuallt formulas in the driver manuals, i think there is a general formula on the linuxcnc wiki

[20:48:25] <ssi> but your drivers max at 30V
[20:48:28] <ssi> so 30V is a winner
[20:49:00] <jdh> or maybe 28v
[20:49:08] <ssi> yeah perhaps
[20:49:12] <renesis> what is the 1000 number?

[20:50:07] <jdh> I run my 24v switcher at 28v for my old router.
[20:50:25] <yeahsup> actually have to of those lying around and have been using my router with both (1 for 2 motors), but since none of those generates considerable heat, I guess my calculations about 2 years ago were "kind of" wrong
