[00:09:00] <les> me too
[00:09:02] <gezr> http://cgi.ebay.com/1000-SOUTH-BEND-STURDIMILL-UNIVERSAL-HORIZONTAL-MILL_W0QQitemZ7522293969QQcategoryZ12584QQrdZ1QQcmdZViewItem
[00:09:05] <Jacky^> they dont' lose value in the time
[00:09:14] <gezr> les if you have a moment let me know if thats decent iron?
[00:09:16] <les> right
[00:09:22] <Jacky^> but hard to find..
[00:10:07] <les> hi gezr
[00:10:10] <les> looking
[00:10:17] <Jacky^> gezr: nice price..
[00:10:28] <gezr> http://www.surplusrecord.com/cgi-bin/ad_spec.pl?402984|P
[00:10:32] <Jacky^> the only prob.. i'm in eu :\
[00:10:33] <gezr> is a newer one I think
[00:10:52] <gezr> Im interested in a small machine with the swivel table
[00:11:10] <les> looks ok...but I am more familiar with cincinatti and b&s
[00:11:34] <les> horizintals go for scrap value these days
[00:11:38] <les> too bad
[00:11:39] <gezr> wow, the second link I posted is uber
[00:11:49] <les> or too good if you want to buy one
[00:11:52] <gezr> I love horizontal, the second one, has a vertical head
[00:12:34] <robin_sz> guys!
[00:12:37] <les> We kept a line of B&S #5 running till 2000
[00:12:47] <gezr> and its not a r8 taper machine :)
[00:12:55] <les> took em out...$250 each to scrap dealer.
[00:12:57] <gezr> man, I think im going to have to get it
[00:13:02] <gezr> robin_sz : howdy
[00:13:05] <les> hi robin
[00:13:19] <robin_sz> are we well?
[00:13:24] <gezr> im in love
[00:13:37] <gezr> http://www.surplusrecord.com/cgi-bin/ad_spec.pl?402984|P
[00:13:38] <robin_sz> not with me!
[00:13:58] <les> lots of engineering work...so yeah well
[00:14:07] <robin_sz> oh, that is nice ...
[00:14:18] <les> just got finished talking to patent lawyers
[00:14:19] <robin_sz> depends how rusty it was before they painted it ..
[00:14:28] <gezr> doesnt matter, have scraper
[00:14:39] <robin_sz> but if its original paint .. then it must have been in a store!
[00:15:24] <robin_sz> very nice, now .. how much is it?
[00:15:33] <les> looks like a clean machine
[00:15:47] <gezr> no idea, ill have to call for quote
[00:15:54] <gezr> but it has the swivel table
[00:16:00] <les> I have been contemplating more shop space
[00:16:04] <gezr> and its not the mit grizzly one
[00:16:18] <les> build another structure or lease industrial space?
[00:16:27] <robin_sz> hmmm
[00:16:29] <gezr> build
[00:16:45] <robin_sz> build if you have the space and funds
[00:16:47] <les> gottas watch it...I am zoned agricultural
[00:17:03] <gezr> call it a barn
[00:17:11] <les> " machine tool farm"?
[00:17:12] <gezr> and just farm the minimal acragage
[00:17:15] <robin_sz> yeah, but "farm diversifaction" is a big thing these days
[00:17:28] <les> yeah...
[00:17:29] <les> and
[00:17:30] <gezr> and if anyone asks tell them, you had a water issue
[00:18:04] <les> I am a farmer...must be...bought a tractor...right?
[00:18:14] <gezr> oh lord, found one for 12,500 us
[00:18:20] <robin_sz> yeah, just say you are relocating operations from your ex New Orleans facility and you'll probably get govmt funding ;)
[00:18:28] <les> haha
[00:18:37] <robin_sz> build if you can ...
[00:18:49] <les> yeah...
[00:18:52] <robin_sz> better than giving money each month to a landlord
[00:19:02] <les> at some point I will live at a factory...
[00:19:13] <robin_sz> plus .. its on your home patch ... you can wander in and out when you want
[00:19:22] <les> I do like that
[00:19:24] <gezr> how many amps to drive 10hp?
[00:19:31] <robin_sz> per phase?
[00:19:42] <gezr> yeah
[00:19:51] <robin_sz> 5.6A at 415 I think
[00:20:42] <gezr> what about 220v, 3 phase rotary converter, to run a 7.5hp motor
[00:21:07] <robin_sz> rotary ... what width of belt?
[00:21:10] <Jacky^> robin_sz: i'm going to order optocouplers..
[00:21:23] <gezr> robin_sz : capicator make up
[00:21:24] <Jacky^> could you take a look to the types ?
[00:21:46] <robin_sz> Jacky^: I use the 2530 HP optos, seem fine
[00:22:03] <robin_sz> gezr: no, what width of belt will it use?
[00:22:13] <gezr> oh I have no idea robin
[00:22:18] <les> my rotary can just start 10 hp.... uses about 30 amps 240 but it's all reactive power
[00:22:36] <Jacky^> robin i found 6n136 or 6n137
[00:22:42] <les> wires don't know that though...
[00:22:45] <robin_sz> gezr: I presume you will run the rotary convertor from pulleys on the overhead spindles .. driven by Oxen?
[00:22:59] <gezr> oh lord
[00:23:06] <robin_sz> or steam?
[00:23:09] <gezr> robin_sz : i mean 2 to 3 phase power converter
[00:23:11] <Jacky^> output opn collector, its ok ?
[00:23:32] <robin_sz> gezr: yeas, but we went electronic *years* ago you know
[00:23:40] <robin_sz> Jacky^: yeah, open collector is fine
[00:23:50] <Jacky^> robin_sz: thanks
[00:23:50] <les> open collector plus 3k pull up resistor=good
[00:24:16] <Jacky^> i will buy 6n137, 10 mb ..
[00:24:19] <Jacky^> :D
[00:24:20] <robin_sz> les: you should see hte optos he has ... with 1K its 3db down at 10khz
[00:24:37] <Jacky^> :\
[00:24:38] <les> I know many optos are slow
[00:24:52] <robin_sz> yeah .. but these are slooooow
[00:24:59] <les> it seems
[00:25:29] <robin_sz> gezr: you can get nice VFDs on eBay... electronic single to 3 pahse .. nice low start currents and many great benefits
[00:25:57] <robin_sz> just re-wire the motor from 415 delta to 220v star and hook it up
[00:25:58] <les> hey Robin...I have ITW finishing systems brass coming here!!!
[00:25:59] <gezr> thats just it, I cannot get 3 phase electrical service at my house
[00:26:16] <les> you know...Binks and Devilbiss
[00:26:36] <robin_sz> gezr: I just said .. they take 220 single in and deliver 220 3 phase out to the motor wired in delta
[00:26:41] <robin_sz> les: wow!
[00:26:47] <les> yeah!
[00:26:52] <robin_sz> les you going to electrify one of them to prove it works?
[00:27:06] <les> haha
[00:27:48] <robin_sz> have them all stand on a 2" slab of polystyrene ... hold hands and we want to see the photo!
[00:28:00] <robin_sz> oh wait no .. they are top brass, probably dont have hair ;)
[00:28:40] <les> They made me join the "100,000 club at ransburg /gema
[00:29:01] <robin_sz> and this was when you had hair too?
[00:29:07] <les> yeah.
[00:29:10] <les> haha
[00:29:32] <les> they liked to do tesla stuff
[00:29:54] <les> you know...above 700 hz high voltage
[00:30:24] <les> light incandescent bulbs from arm to arm
[00:30:25] <robin_sz> gezr: you can do 220 single pahse to 3 pahse with a small block about 6" cube , all electronic and fulltprotected for a few hundred dollars / prbably less expensive than a rotary
[00:30:33] <robin_sz> yeah
[00:30:45] <robin_sz> we have doen similar stuff with RF
[00:31:06] <les> I was quoted about $500 for a 7.5 kW inverter
[00:31:06] <gezr> robin_sz : yeah, my bad, I wasnt thinking about that method
[00:31:17] <robin_sz> some aerial fields, you dont need a torch ... just a flourescent tube
[00:31:29] <les> yeah
[00:31:45] <les> tesla coils
[00:32:12] <robin_sz> droitwich for example ... a pair of 250Kw AM transmitters on 198khz ...
[00:32:44] <les> our lowest is 10 kHz I think...for submarines
[00:32:55] <robin_sz> yeah, wound around a mountain
[00:33:08] <les> prob
[00:33:36] <robin_sz> droitwich we had UV detectors in the field .. incase insulators flashed over ..
[00:33:46] <robin_sz> dropped it to 1/4 power for 0.25 seconds
[00:34:12] <robin_sz> that was the good part
[00:34:18] <les> heh
[00:34:29] <robin_sz> the bad part was it also detected lightning and anyone welding
[00:34:47] <les> hmm
[00:34:52] <robin_sz> and pigeons ...
[00:35:10] <robin_sz> pigeons thought the 600R ladder feeder was a great place to roost
[00:35:33] <robin_sz> the average roosting time was measured in milliseconds ...
[00:35:55] <les> poof?
[00:35:59] <robin_sz> indeed
[00:36:21] <robin_sz> it was AM, 0.5mw average, but 2mw on peaks ..
[00:36:38] <robin_sz> thats real watts, not with aerial gain
[00:36:48] <les> I have a strange problem here....
[00:37:00] <robin_sz> try penicillin?
[00:37:04] <les> the business is suddenly doing well...
[00:37:06] <les> but
[00:37:09] <robin_sz> uh huh ...
[00:37:22] <les> I have forgotten how to spend money!
[00:37:27] <les> weird
[00:37:38] <robin_sz> oh, just let the business do well for a while
[00:37:48] <les> made no money for a couple years
[00:37:49] <robin_sz> the spending money bit will return
[00:37:56] <robin_sz> * robin_sz knows that feeling
[00:38:15] <les> airplanes or women could fix that easily
[00:38:20] <robin_sz> yep
[00:38:35] <les> weird feeling though
[00:38:41] <robin_sz> or start collecting something
[00:38:42] <les> never felt like this
[00:38:59] <robin_sz> well, get a bit put back in the bank eh, for a riany day
[00:39:05] <les> yeah
[00:39:21] <robin_sz> maybe a nice PA38?
[00:39:22] <les> won't always be like this
[00:39:48] <les> I still love archers
[00:39:53] <robin_sz> what about a nice bonsai?
[00:40:02] <les> ??
[00:40:07] <robin_sz> http://www.bonsaikitten.com/
[00:40:12] <les> haha
[00:40:17] <robin_sz> bonsai with cats!
[00:40:24] <les> I saw that
[00:40:25] <gezr> heh
[00:40:34] <robin_sz> its a good hoax :)
[00:41:00] <robin_sz> same crew that did http://www.rentmydaughter.com/
[00:41:27] <gezr> oh my, I hope I can get a good quote on that machine, Ill offer a tad, but if they are "firm" they can let it rust on site
[00:41:38] <les> Ihaw
[00:41:51] <robin_sz> that *really* gets feminists wound up ... they go ballistic
[00:43:41] <les> We will tell you about that later when hillary buys the presidency
[00:43:59] <robin_sz> you mean elected?
[00:44:06] <les> same thing
[00:44:09] <les> hahaha
[00:44:12] <robin_sz> :)
[00:45:07] <les> I seem to not be able to deal with maternal social structures
[00:45:15] <les> having been married twice
[00:46:02] <robin_sz> hmmm
[00:46:12] <les> heh
[00:46:33] <gezr> she is a fine example for women the world over to stand by your man
[00:46:47] <les> i guess
[00:46:49] <gezr> heh
[00:47:21] <gezr> oh les, I still plan on a trip over and down to see you some times
[00:47:24] <gezr> time

[00:47:32] <robin_sz> so, NYC was "interesting"
[00:47:42] <robin_sz> i have to go back in 6 weeks or so
[00:47:44] <les> yeah how was it?
[00:47:58] <robin_sz> mmm .. .well, it will be nice when they modernise it :)
[00:48:05] <les> haha
[00:48:11] <robin_sz> and give it a clean
[00:48:27] <robin_sz> and like the brooklyn bridge ..
[00:48:34] <robin_sz> its a major acces point ..
[00:48:38] <robin_sz> and rusting to fsck
[00:48:58] <robin_sz> but, it was interesting all the same
[00:49:13] <les> Chicago had a lot of rusty old riveted iron bridges
[00:49:17] <les> has
[00:49:52] <robin_sz> you know, you see cop films in NYC and think "wonder how they found that backstreet with the stemaing sewer covers"
[00:49:54] <les> huge amounts of salt are used on the roads in winter
[00:50:09] <robin_sz> then you reallise, they have hundreds of streets like that
[00:50:14] <les> yeah
[00:50:27] <robin_sz> greenwich village wass nice at night
[00:50:43] <robin_sz> chelsea was ... different
[00:50:56] <les> well, I have gone to big city living to way out in the back woods
[00:51:04] <les> miss some things
[00:51:07] <les> not others
[00:51:08] <AchiestDragon> robin_sz: good book to give to feminists , or read your self and practice on wife :)
[00:51:11] <AchiestDragon> http://www.amazon.co.uk/exec/obidos/ASIN/0963976397/qid=1126135925/sr=8-1/ref=sr_8_xs_ap_i1_xgl/026-7094983-8579645
[00:51:13] <robin_sz> yeah, I prefer backwoods
[00:51:29] <les> a little too quiet
[00:52:51] <les> I hope my exes don't read that book
[00:53:39] <robin_sz> AchiestDragon: ;) ... I would buy it for my wife, but she might try and train me instead!
[00:53:58] <les> actually so what if they do...
[00:53:59] <les> haha
[00:54:22] <les> I seem to be untrainable
[00:55:54] <robin_sz> uncontrollable more like!
[00:56:14] <les> even by moonshiner's daughter (last ex)
[00:56:31] <robin_sz> oh yes, I saw the photo ...

[01:00:07] <les> Irish girls make sure you have the time.
[01:00:11] <robin_sz> true
[01:00:19] <gezr> heh
[01:00:20] <robin_sz> any of them tunr into little engineers?
[01:00:35] <les> son and daughter...
[01:00:40] <les> not engineers
[01:00:56] <les> son plays lead guitar in a rock band
[01:01:10] <les> daughter is just at home
[01:01:20] <gezr> you still wont let her go out hu?
[01:01:41] <gezr> I should be ashamed

[01:01:44] <les> haha
[01:02:20] <les> son is kinda wild
[01:02:27] <les> can't control him
[01:02:28] <Jacky^> ghghg ..
[01:02:37] <les> wonder where he got that from?
[01:02:42] <robin_sz> hehe
[01:02:44] <Jacky^> 30 6N137 !
[01:02:52] <Jacky^> E. 23
[01:03:07] <Jacky^> robin_sz: are enough 30 pz ?
[01:03:11] <Jacky^> :D
[01:03:16] <robin_sz> just about
[01:03:23] <robin_sz> you planning on blowing many up?
[01:04:03] <Jacky^> well, 6 for out
[01:04:15] <Jacky^> 3 for input , right ?
[01:04:17] <gezr> whats a 6n137?
[01:04:42] <Jacky^> gezr: a better optocoupler than pc187 :\
[01:04:57] <Jymmm> les: His father, have you ever met him?! :o
[01:05:11] <les> quad or hex is good.
[01:05:37] <robin_sz> for driving stppers, dual is OK
[01:05:40] <robin_sz> step and dir
[01:05:45] <Jymmm> gezr: What, you dont know how to use google???? http://www.isocom.com/6N137.htm
[01:06:00] <les> jymmm: most of my offspring call me daddy...I think
[01:06:14] <gezr> Jymmm : google?
[01:06:16] <robin_sz> * robin_sz sees Jymmm is in non-confrontational mode again
[01:06:16] <Jymmm> les and the neighbors offspring too
[01:06:29] <Jymmm> robin_sz no more than your normal amount.
[01:06:41] <robin_sz> hey, dingbat, you measured the twist on that gantry yet you slacker?>
[01:07:07] <Jymmm> robin_sz Nope, and not gonna either.
[01:07:16] <les> I'm always in non confrontational mode. GOT IT?
[01:07:27] <Jymmm> les got it! =)
[01:07:34] <les> haha
[01:07:38] <robin_sz> you know why dont you? becuase it twists like a bit of bent tin and you wont admit it ;)
[01:07:55] <Jymmm> robin_sz: I could care less.
[01:07:56] <robin_sz> or did you ship it back?
[01:08:58] <les> jymmm needs to make some signs
[01:09:06] <les> I could sub some out
[01:09:16] <Jymmm> les, signs, sawdust, anything at this point=)
[01:09:21] <gezr> les, motion better now?
[01:09:29] <les> yes better
[01:09:36] <les> much
[01:09:53] <Jymmm> les: Just playing at the moment, waiting for replacement parts to arrive.
[01:10:19] <robin_sz> so, still nto right then huh?
[01:10:42] <les> nto right?
[01:10:45] <robin_sz> not
[01:10:49] <les> haha
[01:11:03] <robin_sz> this was excessive play in one axis right?
[01:12:09] <les> .004" backlash...jymmm needs "bigger balls"
[01:12:35] <robin_sz> les: I had a theory that the desing of that router would suffer from excessive twist in the gantry when you pushed one carriage backe, the other one forward, as it was centre leadscrew driven, and had small spacing between the X axis pillow blocks
[01:12:58] <robin_sz> especially with the gantry at "mid X" position
[01:13:06] <robin_sz> as there is no bracing across the base
[01:13:24] <les> wel you know I am not a big fan of single screw gantries
[01:13:31] <robin_sz> well .. yeah
[01:13:49] <robin_sz> they CAN work, but only if the X pillow block spacing is large
[01:13:58] <robin_sz> they work OK on sliding table designs
[01:14:11] <les> anything under square is pushing it really
[01:14:15] <robin_sz> yeah
[01:14:28] <robin_sz> and that desing is like 4:1 under square
[01:14:55] <les> lots of deflection
[01:15:00] <les> but...
[01:15:05] <les> it is wood only
[01:15:07] <robin_sz> I suspect with like 200N the dflection will be over 2mm
[01:15:18] <les> easily
[01:15:28] <Jacky^> * Jacky^ loves wood
[01:15:31] <robin_sz> which I would say is unworkable
[01:15:43] <robin_sz> unless you have jerk-limited motion
[01:16:02] <les> well... 100N is typical for wood routers
[01:16:07] <robin_sz> yeah
[01:16:18] <gezr> what law would say that thing of motion should be as close to slide to make right?
[01:16:27] <robin_sz> sadly, for some reason Jymmm refuses to divulge the amount ...
[01:16:39] <les> haha
[01:16:41] <gezr> jymmm is having fun
[01:16:57] <robin_sz> well, thats ok, because Ive seen his website
[01:17:12] <Jacky^> les: what about 3D homebuild scanner ? how they work, never tried one ?
[01:17:15] <gezr> I havent got a machine because I stay focused on specific things, instead of action
[01:17:20] <les> well he can always make foasm signs...cutting force=zero
[01:17:24] <les> foam
[01:17:35] <gezr> at least he has something that moves
[01:17:35] <robin_sz> les: well, yeah but its not just cutting force is it ...
[01:17:47] <robin_sz> theres the mass of the router ...
[01:17:51] <gezr> I have managed to build one simple acme screw drawer slide
[01:18:29] <robin_sz> with unbounded jerk a 5kg router at one side of the gantry will play hell
[01:19:27] <gezr> robin_sz : he may decide, to go with 2 screws, linked together with a timming belt, and a single drive motor
[01:19:42] <les> I used a jackshaft
[01:19:52] <les> works well
[01:19:56] <gezr> would timming belts be okay?
[01:19:58] <les> expensive though
[01:20:02] <robin_sz> yeah, that would help a lot, BUT when you buy someting new, you expect it to work, right?
[01:20:13] <robin_sz> timing belts are fine, doen that before
[01:20:38] <gezr> robin_sz : are we talking bulets?
[01:21:12] <Jymmm> What CAM is everyone using?
[01:21:25] <gezr> turbocad gonna probably get trubocam some day
[01:21:36] <robin_sz> * robin_sz only does 2.5D these days ...
[01:21:43] <Jacky^> Jymmm: logitech :)
[01:21:52] <gezr> its windos, and ive owned the software for years, but I can hardly use it
[01:22:18] <gezr> yeah I think its only 2.5 as well, but I dont know, havent tried the cam stuff out, they want 300 bucks from me for full version
[01:22:28] <robin_sz> depends on what you wanna do? 3d relief stuff? signmaking? art? engineering?
[01:22:31] <robin_sz> may options
[01:22:41] <robin_sz> for engineering, Visual Mill ...
[01:22:50] <robin_sz> for art, artcam or Type3
[01:23:08] <les> jymmm I use millwrite mostly for signs
[01:23:09] <gezr> or master gcode
[01:23:18] <les> and artcam
[01:23:22] <robin_sz> for signs, Scanvec Enroute or Inspire or EngraveLab
[01:23:23] <les> sometimes
[01:23:26] <gezr> which if you have tons of lines, youll lose your mind
[01:23:38] <Jymmm> les : I got ahold of the guy today, will be ordering .1245" .1250" .1255"
[01:23:58] <gezr> Jymmm : eh?
[01:24:09] <gezr> I know it was to less, but that pretty close to each other somethings
[01:24:17] <Jymmm> les He almost immediately asked about spacers too
[01:24:20] <gezr> err, les not less, les is more
[01:24:31] <robin_sz> gezr: ball bearins for the faulty ballscrew
[01:24:35] <Jymmm> no, les is less, but les is more
[01:24:44] <robin_sz> more or less
[01:24:50] <gezr> Jymmm : whats faulty about your balls?
[01:25:03] <Jymmm> gezr: Nothing, just not preloaded.
[01:25:10] <gezr> oh, shit
[01:25:15] <gezr> let me check, my balls really quick
[01:25:24] <robin_sz> gezr: you havent seen his website, then you'd know whats worng with his balls ;)
[01:25:47] <les> some use spacers and some do not
[01:25:50] <Jymmm> gezr They are within specs/tolerance, just want to clean them up as much as possible.
[01:25:59] <les> but
[01:26:18] <les> if you are at .124 and have .004 backlash....
[01:26:41] <les> will need more than .1255
[01:26:44] <les> I think
[01:26:48] <les> but try it
[01:26:55] <gezr> my balls are like .125~ ish, I have a 2x2" box full of them
[01:27:02] <gezr> Jymmm : web site?
[01:27:03] <les> it will be a n education
[01:27:10] <Jymmm> les: Well, I said that to him too. and he said way too big.
[01:27:20] <les> really
[01:27:20] <gezr> Jymmm : are the screws hardned?
[01:27:27] <gezr> and currently not flaking at all?
[01:27:37] <Jymmm> les said to try the smaller increments as it's really half.
[01:27:46] <les> well, he must be the expert. Try it.
[01:27:58] <Jymmm> les he says he'll have ppl right at the counter swapping out the balls befor ethey even leave.
[01:28:07] <Jymmm> gezr JAS
[01:28:10] <gezr> I can send some of my balls to you, or inspect some for you, if they arnt charging you an arm and leg for replacements?
[01:28:31] <gezr> Jymmm : whats your web site, I dont think I have it bookmarked
[01:28:41] <Jymmm> gezr: These are Chrome Alloy, grade 25
[01:28:57] <Jymmm> gezr http://www.precisionballs.com/StandardCommercialBallsDirectory.htm
[01:29:08] <gezr> the balls I have are ball screw balls, not a rack of bearings, I mean your web site?
[01:29:42] <robin_sz> now, im having fun :)
[01:30:08] <les> ?
[01:30:17] <Jymmm> les: He's working on a 4" ball that's withing 2 millionths.
[01:30:25] <les> wow
[01:30:34] <robin_sz> how handy :)
[01:30:41] <Jymmm> les DOE stuff
[01:30:54] <gezr> a ball that size would definately go with les's shuttle tank model
[01:31:38] <les> actually the ball bearing manufacturing process is a foundation of the industrial revolution
[01:31:47] <gezr> speaking of the foam, cant they just wrap some wire around that damn thing after its been insulated?
[01:32:02] <gezr> les : you mean a wire mes screen and a water bucket?
[01:32:15] <les> haha
[01:32:22] <robin_sz> or some sort of polymer net
[01:32:46] <gezr> les : that is sorta what they did at first isnt it?
[01:32:48] <les> or
[01:33:13] <gezr> motel metal, poured into a fine wire mesh screen, then water to quench the balls in
[01:33:16] <robin_sz> gezr: its afairly basic process using two plates and some grinding paste
[01:33:26] <les> do dodecahedral closed packed balls in a slurry all tend to be the same size when tumbled?
[01:34:12] <gezr> no?
[01:34:12] <les> I think not since the two plate method is used
[01:34:35] <robin_sz> its fairly basic technology, they probably did it that way from early on
[01:34:49] <gezr> ive never looked into ball making
[01:34:49] <robin_sz> right, wife in shower .. I must go ;)
[01:34:56] <gezr> heh
[01:34:57] <robin_sz> later guys
[01:35:03] <les> joining her?
[01:35:14] <gezr> he may be thinking he will be
[01:35:19] <les> haha
[01:35:40] <les> perhaps...she's half irish
[01:35:54] <gezr> heh
[01:36:09] <gezr> les hey, you think that south bend horizontal is a nice machine to have in the garrage?
[01:36:21] <gezr> the swivel table would really be uber for gears
[01:36:25] <les> it looked ok
[01:36:43] <gezr> I havent got my gear nut yet
[01:36:49] <les> those things can take off some serious metal
[01:37:20] <gezr> you know I would love to have something that size to produce my cnc mini mills
[01:37:25] <gezr> and gears
[01:37:31] <gezr> lots and lots of gears
[01:38:09] <les> all gears, like everything else, are made in china.
[01:38:12] <les> haha
[01:38:14] <gezr> I would have it shopped to where I work, would have to take it apart, take it home in bits, and put it all back together
[01:38:29] <gezr> hey, you know that grizzly I was asking about?
[01:38:42] <gezr> I emailed a guy who got one, he was disapointed with it, and hardly used it
[01:38:56] <gezr> he said the horizontal spindle burned out quickly as well
[01:39:07] <les> but really, I am making a pretty good living with old post industrial tooling
[01:39:19] <les> wonder why?
[01:39:37] <Jymmm> les your legs must get tired turnin that spindle all day long
[01:39:46] <les> every one else is melting them down
[01:40:14] <gezr> les : look, either I buy something like tha tone, or just give up all together you know
[01:40:16] <Jymmm> les OH... you said POST, I thought you said PRE =)
[01:40:28] <les> haha
[01:40:53] <gezr> Ive ran huge equipment, and know what it takes to make chips fly
[01:41:16] <les> really...I buy old machines that industry can't use any more...and I'm making pretty good money!
[01:41:19] <les> why?
[01:41:25] <gezr> an uber horizontal that can launch chips of flaming metal out my garrage, over my car and into the street would just do it to it
[01:42:03] <Jymmm> les becasue you know what you are doing?!
[01:42:10] <gezr> and probably piss everyone off, but I would do it as a distraction for the teenagers, who think its cool to wind out the 4 wheeler, that uncle joe brought over
[01:42:13] <les> haha
[01:42:37] <les> well I do engineering...but I have to have machine tools to make ideas a reality
[01:42:40] <gezr> I can make chips fly with a hand drill
[01:42:56] <Jymmm> gezr I prefer a hand grinder
[01:43:16] <les> I was looking at drill presses today...perhaps need a bigger one
[01:43:36] <les> a gear head one
[01:43:48] <gezr> colum type les?
[01:43:55] <les> I guess
[01:44:16] <les> now with big holes I just do them on the mill
[01:44:16] <gezr> the one we have at work, is from the 40s I guess, and it has been worn de hell out
[01:44:46] <gezr> even a large, raidal arm press, is going to be hard pressed to punch 2.5" holes
[01:44:59] <gezr> unless using indexable carbide drills
[01:45:13] <les> I don't know...I am just upping the hp and size of everything as business grows
[01:45:27] <les> tools are so cheap to buy now
[01:45:50] <les> they are almost free.
[01:45:55] <Jymmm> ?
[01:45:59] <gezr> not the shit im looking at
[01:46:13] <gezr> at each turn, it hit some magical point and the price goes up 10x
[01:46:13] <les> compared to labor
[01:46:57] <les> you can buy a nice little VMC for 30k
[01:47:02] <les> amazing really
[01:47:10] <gezr> les : after thinking about mit machines and what yall said, ive have resorted to old iron that I really have no business putting into a garrage, instead of a mit bridgeport
[01:47:28] <gezr> mit that is yeah
[01:47:45] <gezr> I just want good ole iron
[01:48:02] <gezr> and I can rebuild, repair at will, and have something I can be proud of I guess
[01:48:14] <les> I have made a lot of successful product prototypes on a vertical mill made in 1942
[01:48:49] <gezr> we ask the old guy at work sometimes, what is was like carving stone with Moses
[01:48:54] <Jymmm> old say holds true.... they dont make things like they used to.
[01:49:08] <les> getting a second one...but will keep and still use the old one
[01:49:20] <gezr> the new stuff is good too, it just doesnt seem to last
[01:49:33] <les> I fixed it up...it runs sweet
[01:49:36] <Jymmm> gezr then is not that good is it?
[01:49:52] <gezr> take mini mills, there are tons of pages dedicated just to making them good
[01:50:02] <gezr> Jymmm : its a mater of perspective you kow
[01:50:07] <Jymmm> les Did I mention that I can only get 90 IPM under win/nix, but can get 180IPM under DOS ?
[01:50:45] <les> I was going to just get a series 2 to run with emc...but now I think a small VMC would be better
[01:50:53] <gezr> I have a friend with a really nice, mit, enco chage belt mill, the thing is awsome
[01:51:08] <gezr> ive seen a lot of series 2 machines on ebay lately
[01:51:12] <les> jymmm dos is soft real time if you don't flush buffers
[01:52:27] <les> I need to work on emc auto tool change stuff...it's not quite there
[01:52:59] <gezr> im goign to go to bed you guys
[01:53:08] <gezr> Jymmm : let me know if you cant get a good price on balls
[01:53:14] <les> early!!!
[01:53:16] <gezr> Jymmm : I can measure you out a few sets
[01:53:27] <gezr> I have to go to sleep early for work, it keeps me happy at work
[01:53:36] <les> ah ok
[01:53:52] <gezr> Jymmm : or just send you a set or 2, and let you repack your screws and see what you think
[01:54:04] <gezr> that way your not out a dime
[01:55:01] <gezr> just let me know
[01:55:14] <gezr> or not, doesnt really mater, but I dont mind doing it for you
[01:55:38] <Jymmm> les say what?
[01:56:02] <Jymmm> gezr: Ah, very cool. You have them in those increments?
[01:56:15] <LawrenceG> Jymmm... what are the balls worth?
[01:56:27] <gezr> well, those increments, I would have to check, I think what I have is a box of 1/8th inch balls
[01:56:44] <gezr> I must have over 600 of the darn things
[01:56:59] <LawrenceG> dont drop the box!
[01:57:33] <gezr> I think I spilled 20 or more balls just checking it out earlier
[01:57:55] <les> There may be a reason thomson uses such undersize balls...like short term lead error. We'll see.
[01:58:18] <gezr> well if they get too tight, they will flake the nut casing, and the screw
[01:58:29] <les> right
[01:58:39] <gezr> and thats wicked bad ugly
[01:58:57] <Jymmm> LawrenceG .125" he said are cheap. His biggest thing was me meeting the $20 minimum order, I think that'll be no boggy
[01:59:13] <gezr> Jymmm : let me ship you some, how many do you need?
[01:59:26] <les> mine use oversize balls...i.e. they have to be forced in
[02:01:58] <Jymmm> gezr 37,000,000
[02:02:00] <les> but very very good lead accuracy is required to do that
[02:02:17] <Jymmm> les what did you mean when you said something about DOS ?
[02:02:25] <LawrenceG> hi les,,,
[02:02:26] <les> dos?
[02:02:36] <les> it can be soft reat time
[02:02:37] <Jymmm> les dos is soft real time if you don't flush buffers
[02:02:44] <Jymmm> les what do you mean by that?
[02:03:02] <les> don't write to the hard drive!
[02:03:20] <LawrenceG> or update a display
[02:03:21] <Jymmm> gezr: They have a $20 min order, plus I dont know if .125 is the right size
[02:03:26] <les> yeah
[02:03:51] <Jymmm> les: Ah, well I couldn't get >90IPM under anythign else.
[02:04:06] <LawrenceG> scrolling the screen puts wicked hickups in the pulse train
[02:04:19] <gezr> Jymmm : if you want me to, I can inspect enough balls for you to get an idea as to what you need, and let you decide on what you need to buy
[02:04:31] <gezr> Jymmm : do you know the exact size of your current balls?
[02:04:36] <Jymmm> .124
[02:04:49] <gezr> let me go inspect one really quick
[02:04:51] <les> Well, general purpose microprocessors tend to be poor signal generators!
[02:05:47] <les> Of course I use servos in machine tools.
[02:05:57] <Jymmm> les: Well, before I go spending more money on a sig gen, I need to start paying for what I got, then go on from there.
[02:06:05] <LawrenceG> especially when users keep wanting to poke at the keyboard and expecting a response
[02:06:10] <les> there is an exception:
[02:06:16] <les> ther paint robot
[02:06:22] <les> usinf steppers there
[02:06:36] <les> inherently explosion proof?
[02:07:02] <Jymmm> les wheres the fun in that?!
[02:07:07] <les> heh
[02:07:25] <Jymmm> les dont forget to hipot test it while in operation too
[02:07:54] <les> I just ground everything
[02:08:05] <Jymmm> again, wheeres the fun in that?
[02:08:05] <gezr> Jymmm : .1248 give or take a tenth, using a rough set, v anvil mic
[02:08:40] <gezr> just touching the damn balls, makes em larger
[02:08:46] <Jymmm> lol
[02:09:07] <gezr> how many do you want
[02:09:13] <Jymmm> it's all good, they shouldn't charge me too much for a variety of sizes.
[02:09:30] <Jymmm> they are all cert too
[02:09:43] <Jymmm> gezr do you know the material/grade?
[02:09:56] <gezr> just that they are for ball screws
[02:10:38] <Jymmm> gezr: Thanks for the offer, but I'd rather not take a chance.
[02:10:52] <gezr> thats cool, and fully understandable
[02:11:36] <Jymmm> Now, if you have a double tube ballnut =)
[02:11:36] <gezr> les : when you repack balls, did you use greese to help hold things together a bit?
[02:12:11] <Jymmm> I reworked the return tube with a file... seats much better now.
[02:12:53] <Jymmm> this fscking tooth of mine... bbl
[02:13:14] <les> gezr, I didn't. I just hung around at the HIWIN facility and talked to the people that repacked the nuts
[02:13:20] <les> and watched them
[02:13:33] <les> toothache?
[02:13:48] <gezr> les : you know how to flake/frost right?
[02:13:56] <les> sure
[02:14:15] <gezr> okay, goodnight, maybe more talke morrow
[02:14:29] <les> ok good night
[03:40:21] <Jymmm> you leaving les?
[03:41:12] <Jymmm> les : Yeah, toothache.
[04:51:25] <A-L-P-H-A> but you don't type with your tooth.
[05:01:33] <Jymmm> ?
[05:03:11] <A-L-P-H-A> sure
[05:58:37] <Jymmm> know of any digital probes?
[05:59:01] <A-L-P-H-A> none that are affordable for me.
[05:59:15] <A-L-P-H-A> I know some optical ones... omron.
[05:59:20] <Jymmm> what about a DIY one?
[05:59:22] <A-L-P-H-A> which freak'n reminds me.
[05:59:26] <A-L-P-H-A> digital?
[05:59:28] <A-L-P-H-A> yeah.
[05:59:31] <A-L-P-H-A> tach sensor.
[05:59:40] <Jymmm> resolution?
[05:59:41] <A-L-P-H-A> www.dakeng.com there's a circuit for a tach prob.
[05:59:52] <A-L-P-H-A> resolution ones are best bought off ebay.
[06:00:15] <Jymmm> dont see one on dakeng
[06:01:05] <A-L-P-H-A> sec
[06:01:31] <A-L-P-H-A> http://www.dakeng.com/threading.html
[06:02:32] <Jymmm> I need to measure depth, not rpm
[06:17:04] <A-L-P-H-A> Jymmm, oh a digital prob?
[06:17:36] <A-L-P-H-A> hack a calipre... or search USPatent for digital prob... there's schematics on there... no dimensions, just schematics.
[06:17:52] <A-L-P-H-A> and a digital prob, can be bought for like $60USD... maybe even cheaper on ebay.
[06:18:56] <Jymmm> http://cgi.ebay.com/Solatron-digital-probe_W0QQitemZ7542981621QQcategoryZ41938QQrdZ1QQcmdZViewItem
[06:20:33] <A-L-P-H-A> no clue.
[06:20:40] <Jymmm> me neither =)
[06:20:47] <A-L-P-H-A> the one I was thinking off, has an audiable sound, or a LED that goes on/off
[06:20:55] <A-L-P-H-A> which would be easy to hack to send a digital signal.
[06:24:31] <Jymmm> heh, I found one, and only one.
[08:15:06] <A-L-P-H-A> damn it's warm in my room.
[08:15:11] <A-L-P-H-A> and it's like 20oC outside to.
[08:15:14] <A-L-P-H-A> time to open a window
[08:50:08] <A-L-P-H-A> hmm.... I found a new favourite word... hehe... callipygian
[09:36:08] <A-L-P-H-A> I'm on ubuntu! and I am Happy!
[09:36:31] <alex_joni> heh
[09:36:34] <alex_joni> nice
[09:36:39] <alex_joni> does it hurt?
[09:38:44] <A-L-P-H-A> no.
[09:38:49] <A-L-P-H-A> it hurt before...
[09:38:55] <A-L-P-H-A> as I couldn't get my mouse to work.
[09:39:01] <A-L-P-H-A> it was a kernel problem.
[09:39:04] <A-L-P-H-A> solved by others...
[09:39:10] <A-L-P-H-A> now I'm happy, and it's working! :D
[09:39:19] <alex_joni> coo
[09:39:45] <A-L-P-H-A> reinstalled it completely... and I have notes on my gmail account, which I'm redoing.
[09:40:38] <A-L-P-H-A> what where the two emc wiki pages?
[09:40:43] <A-L-P-H-A> there's the official, and the unofficial.
[09:40:47] <A-L-P-H-A> I don't remember the unofficial.
[09:41:20] <alex_joni> me neither
[09:42:11] <A-L-P-H-A> alex_joni, you remember what I'm talking about?
[09:42:19] <alex_joni> yeah
[09:44:17] <A-L-P-H-A> how to I restart X? alt-control-backspace?
[09:44:44] <alex_joni> lol.. yeah
[09:45:38] <A-L-P-H-A> nm. :) hahaha
[09:48:10] <A-L-P-H-A> now I'm trying to find my ipod.
[09:48:10] <A-L-P-H-A> :/
[09:48:24] <alex_joni> try : updatedb
[09:48:26] <alex_joni> and locate
[09:48:31] <alex_joni> ROFLMAO
[09:48:45] <A-L-P-H-A> haha
[09:48:54] <A-L-P-H-A> I don't know what device it is...
[09:49:16] <alex_joni> try /dev/ipod*
[09:50:23] <A-L-P-H-A> no ipod
[09:50:31] <A-L-P-H-A> it's linked via firewire.
[09:50:37] <A-L-P-H-A> the partion manager thing, found it.
[09:50:42] <A-L-P-H-A> identified it as a HP-ipod
[09:50:53] <A-L-P-H-A> there is an HPET.
[10:04:58] <A-L-P-H-A> buahahha... unplug, and replug in. wham. done. mounted.
[10:05:00] <A-L-P-H-A> hahahaha
[10:05:11] <A-L-P-H-A> linux has come so far... I'm about to cry
[10:10:49] <alex_joni> yeah
[10:10:54] <alex_joni> * alex_joni goes away for a while
[10:10:55] <alex_joni> laters
[10:14:15] <A-L-P-H-A> :( my wiki page got pruned.
[10:15:34] <A-L-P-H-A> oh, wrong page. heh
[10:28:32] <A-L-P-H-A> what's better? evolution or thunderbird?

[18:55:00] <Jacky^> * Jacky^ mumble mumble..
[21:48:52] <Jacky^> hola
[21:48:56] <Jacky^> hi bosone
[21:49:08] <bosone> Hi
[21:49:27] <Jacky^> whats in italy ? :P
[21:49:53] <bosone> i'm new user of emc,
[21:50:14] <Jacky^> youre welcome.
[21:50:15] <bosone> i'm from rome
[21:50:24] <Jacky^> rome ? nice
[21:50:30] <bosone> and you?
[21:50:50] <Jacky^> from SI
[21:51:04] <Jacky^> how is the weather there ?
[21:51:40] <Jacky^> here storm.. damn storm
[21:52:12] <bosone> cloudy, sorry for my english. i have an old x y plotter fom sekonic
[21:52:31] <Jacky^> bad english ?
[21:52:45] <Jacky^> ouch .. please speak correct english here
[21:52:49] <bosone> yes
[21:52:52] <Jacky^> ok
[21:53:17] <Jacky^> i can try to speak a little of italian..
[21:53:21] <cradek> he's kidding - any english is fine
[21:53:21] <Jacky^> lets try ..
[21:53:30] <Jacky^> problem hai ?
[21:53:38] <Jacky^> :D
[21:53:59] <Jacky^> ah bosoooo
[21:54:02] <Jacky^> sono italiano !
[21:54:04] <Jacky^> lol
[21:54:05] <Jacky^> :D
[21:54:13] <Jacky^> ok.. kidding ..
[21:54:22] <cradek> Jacky^: you're not a big help here
[21:54:30] <Jacky^> :)
[21:54:36] <bosone> my problem is how to use only 2 axis and z on/off
[21:55:06] <cradek> instead of using the Z axis you can use a coordinated digital output
[21:55:23] <cradek> M62, M63
[21:56:23] <bosone> i modified the plotter with L297/L298 for the two axis, and now ....
[21:57:26] <bosone> for the lpt port, but i don't know how to connect the pen actuator.
[21:57:30] <cradek> is Z a solenoid that requires a digital input?
[21:57:42] <bosone> yes!
[21:57:54] <cradek> you have to drive the solenoid with a pin from the parallel port
[21:58:00] <cradek> you will need to make a simple transistor driver
[21:58:11] <cradek> then write your G code using M62 and M63
[21:58:40] <bosone> ok, and set some ini file?
[21:59:04] <cradek> M62 P8 = turn on bit 8
[21:59:10] <cradek> M63 P8 = turn off bit 8
[21:59:21] <bosone> great!
[21:59:26] <Jacky^> :)
[21:59:29] <cradek> or maybe it's M64/65
[21:59:40] <cradek> I don't remember!
[21:59:43] <cradek> anyway that's the general idea you will use
[22:00:10] <cradek> some people use this to run a laser
[22:00:17] <cradek> exactly the same idea as your plotter
[22:01:11] <bosone> i'd like to use my plotter for pcb prototype
[22:01:26] <cradek> can you draw with an etch resistant pen?
[22:01:36] <cradek> I also wanted to do that with my old plotter, but never did
[22:03:02] <cradek> bosone: my plotter has different pen pressures for felt tip or roller ball or drafting pens
[22:03:10] <cradek> so it is not simply a digital solenoid
[22:03:20] <cradek> I'm not sure how the variable pressure worked
[22:03:32] <alex_joni> hi guys
[22:03:35] <Jacky^> bosone: why do not build a 3 axis machine and mill too ?
[22:03:36] <Jymmm> pulse rate == pressure
[22:03:39] <cradek> hello
[22:03:43] <Jacky^> hi alex_joni
[22:03:51] <cradek> Jymmm: PWM, I assume
[22:03:56] <bosone> lot time ago with indelebile pen and hp7470 plotter (hpgl protocol) directli on pcb
[22:04:01] <Jymmm> cradek yeah, seems simplest method
[22:04:28] <cradek> bosone: did it etch properly when just drawn with a pen? I've had bad luck with those pens
[22:04:31] <bosone> i have a big laser
[22:04:47] <Jacky^> yum :)
[22:05:04] <bosone> produced from SDL
[22:06:20] <Jacky^> right this afternoon, i was thinking how to directly print a pcb using a lesr printer..
[22:06:29] <Jacky^> laser*
[22:06:31] <bosone> at work i used a machine for pcb, but the drill head is very expensive!!
[22:07:02] <bosone> on ebay i found my laser
[22:07:45] <bosone> at about 130$
[22:07:46] <Jacky^> bosone: its seem to me absourd to use a laser for pcb ..
[22:08:06] <Jacky^> for what you mean
[22:08:18] <bosone> why?
[22:08:24] <Jacky^> when you can build a complete machine with about 200 e.
[22:08:28] <Jacky^> 3 axis
[22:08:41] <Jacky^> wich wor area you need ?
[22:08:57] <bosone> A3
[22:09:08] <Jacky^> thats ok ..
[22:09:39] <Jacky^> you can find stepper on micromed for E. 5
[22:09:55] <Jacky^> with a dremel youre ok
[22:10:02] <Jacky^> its funny :D
[22:10:25] <Jacky^> also, you can use some old printer
[22:10:31] <alex_joni> cradek: you have some photographic expierence, right?
[22:11:08] <Jacky^> * Jacky^ bosone
[22:11:13] <Jacky^> ops ..
[22:17:17] <bosone> use someone emc for pcb creation?
[22:17:43] <alex_joni> bosone: cradek does
[22:18:00] <Jacky^> eagle can produce gcode for pcb
[22:18:31] <bosone> eagle can import gerber?
[22:18:52] <Jymmm> hey alex_joni
[22:18:59] <alex_joni> hey Jymmm
[22:19:17] <alex_joni> * alex_joni is still looking at D50 and D350 XT
[22:19:30] <Jymmm> alex_joni sucks to be you
[22:19:31] <Jymmm> =)
[22:19:41] <alex_joni> not so sure ;)
[22:19:52] <jepler> alex_joni: You mean 350D? I have the 300D. I'm still happy with it after a year and a half.
[22:19:57] <Jacky^> bosone: eagle can produce gcode, no idea if it can import..
[22:20:00] <alex_joni> jepler: hey
[22:20:13] <alex_joni> wanted to bug you about this
[22:20:17] <alex_joni> but you weren't around
[22:20:39] <alex_joni> yes, the canon 350D Rebel XT
[22:20:42] <jepler> a friend just bought D70 and he likes it. The included lens is nicer than my first lens.
[22:20:57] <jepler> alex_joni: any specific questions?
[22:21:00] <alex_joni> I've seen a nice package (350D with 2 lenses)
[22:21:06] <alex_joni> what would you pick :D
[22:21:17] <alex_joni> say.. you didn't have any canon or nikon lenses
[22:21:43] <alex_joni> I like the 350D for the optional battery pack
[22:21:51] <jepler> What two lenses? The Sigma 18-50 and 55-200 are the lenses I started with
[22:21:58] <alex_joni> smthg like that
[22:22:17] <alex_joni> was about 1k overall iirc
[22:22:30] <bosone> excuseme, gcode from eagle can drive my solenoid (or laser) by bit 8/M62/G63?
[22:22:53] <alex_joni> bosone: it should, and if not you might tweak it with a script to do so
[22:23:04] <Jacky^> bosone: probably, not .. you need manually add the commands to do it
[22:23:22] <jepler> bosone: gcode generation in eagle is done in their user programming language (ULP) so you can customize the porgram to give the appropriate commands.
[22:24:02] <Jacky^> it seem always a good thing to learn a little of gcode..
[22:24:16] <jepler> bosone: there are contributed scripts on the cadsoft website, but cradek and I use a customized one which is at http://unpy.net/cgi-bin/viewcvs.cgi/eagle/ulp/gcode.ulp
[22:24:40] <jepler> bosone: (the 1.2 version is well tested, the 1.3 version isn't)
[22:25:15] <Jacky^> just yesterday i ordered from rs-components 20 uln2003 ..
[22:25:18] <alex_joni> jepler: http://www.dpreview.com/reviews/CanonEOS350D/Images/NewFeatures/bge3.jpg
[22:25:41] <bosone> ok, thanks to all !! now i'm going to complete my hardware. see you leater.
[22:26:01] <Jacky^> today, looking i found already have 40 mc1413, equivalent ! doh
[22:26:14] <Jacky^> :(�
[22:26:28] <jepler> alex_joni: how much shooting are you going to do, and how much will you use the flash? I find that one freshly charged battery lasts over 2 full days, but I shoot with flash only rarely.
[22:26:42] <Jacky^> bosone: ciao :) alla prossima ;)
[22:26:43] <alex_joni> I don't like battery packs ;)
[22:27:07] <alex_joni> same here (about flash), but I find myself on trips where I can't recharge
[22:27:17] <alex_joni> and I don't want to pack a lot of packs
[22:27:43] <jepler> alex_joni: where you can't recharge? You mean camping or something?
[22:27:43] <alex_joni> so I prefer that battery pack as it can hold normal batteries (if I read it corectly)
[22:27:47] <alex_joni> yeah
[22:27:58] <jepler> You need a product like this one. http://www.realgoods.com/renew/shop/product.cfm/dp/1000/sd/1006/ts/5410182
[22:28:21] <jepler> there are similar things made specifically to work with camera battery chargers, too, but I think they're just a bundle with the 12V automotive version of the charger included.
[22:28:21] <alex_joni> lol, yeah
[22:28:29] <alex_joni> what if it rains?
[22:28:30] <alex_joni> :D
[22:28:33] <Jymmm> alex_joni I use recharable batteries
[22:28:47] <alex_joni> Jymmm: fit into the D50 ?
[22:28:55] <Jymmm> fuck if I know
[22:28:58] <Jymmm> D70
[22:29:05] <alex_joni> right
[22:29:13] <alex_joni> normal rechargeables?
[22:29:18] <alex_joni> AA ?
[22:29:27] <alex_joni> or Nikon foobar ?
[22:29:44] <Jymmm> no, batpack. but comes with a holder for usinf cr22 iirc
[22:30:13] <Jymmm> SB800 uses AA
[22:30:32] <alex_joni> sb800 ?
[22:30:33] <Jymmm> but it's high drain, the camera isn't
[22:30:48] <Jymmm> sb800 speed light

[22:47:19] <alex_joni> paul_c: the changelog seems outdated
[22:52:38] <paul_c> Change.log is fine.
[22:53:19] <alex_joni> ok ;)
[22:53:31] <alex_joni> * alex_joni waits till tomorrow, maybe a new version comes up :P
[22:55:21] <paul_c> That's the last one.
[22:55:41] <alex_joni> I'm sure you had enough of them
[22:56:06] <Yuga> hi all
[23:02:15] <paul_c> "had enough of them" is, um.. close enough.
[23:02:31] <alex_joni> figures
[23:08:12] <paul_c> hey... Did you realise libnml is over 50% smaller than rcslib ?
[23:08:40] <alex_joni> heh.. lots of crap ;)
[23:08:44] <alex_joni> removed I mean
[23:17:28] <paul_c> There is/was quite a bit of redundant code in there..
[23:31:04] <alex_joni> night guys
[23:32:21] <Jymmm> hi paul_c
[23:34:06] <paul_c> Yes Jymmm...
