[00:00:03] <pink84> pink84 is now known as punk84
[00:34:05] <punk84> .
[00:46:21] <Phydbleep> punk84: If you're worried about the 5V line you can use a LM7805 with a heatsink tied across the 12V to get 5V.
[00:46:58] <Phydbleep> LM7805 = 5V voltage regulator.
[00:50:51] <punk84> ok, thx
[00:51:48] <Phydbleep> Dunno about the limit switch issue though..
[00:51:58] <Phydbleep> * Phydbleep is still building a machine.
[00:52:36] <cradek> if your 5v is high, so is the 5v running your parallel port - there will be no problem feeding it into the port.
[00:52:57] <Phydbleep> True. :)
[00:53:04] <cradek> it's also possible that your measurement is wrong if you have a cheap meter.
[00:53:14] <Phydbleep> Too True. :)
[00:53:19] <Jymmm> or cheap power supply
[00:53:37] <Phydbleep> * Phydbleep has lots of cheap meters and averages between several. :)
[00:53:45] <punk84> cheap ps :)
[00:54:00] <Jymmm> * Jymmm hugs his Fluke 77
[00:54:27] <Phydbleep> Check the hardware monitor in the bios and it will tell you what the mb thinks the +5V line is at. :)
[00:55:05] <punk84> true, did not think of that
[00:55:23] <Jymmm> oh, like that's accurate =)
[00:56:10] <cradek> really none of this matters - just use it, whatever it is
[00:56:27] <Jymmm> what cradek said
[00:56:34] <Phydbleep> * Phydbleep tries 'man -K volt'
[00:56:35] <punk84> k i will
[00:57:19] <Jymmm> punk84 : [16:04:34] <Jymmm> 5.2V itself will be fine.... =)
[01:00:50] <cradek> Jymmm: nobody trusts what you say if you pervert your punctuation into smileyfaces.
[01:01:55] <Phydbleep> Jymmm: No punctuating your perversions either.. :)
[01:02:14] <cradek> look out, it's an epidemic!
[01:02:30] <cradek> * cradek washes his hands obsessively
[01:03:31] <Phydbleep> cradek: :þ
[01:03:37] <Phydbleep> Hehehe.. :)
[01:18:07] <Phydbleep> BTW.. For those that asked about the character.. þ = Unicode 00fe
[01:24:24] <Jymmm> cradek =)
[01:24:35] <Jymmm> >:]
[01:34:57] <Phydbleep> punk84: I don't know if it's part of the distro you have, but 'gkrellm' on FC3 has a voltage monitor.
[02:02:11] <A-L-P-H-A> missed me people? :)
[02:20:21] <Phydbleep> A-L-P-H-A: Yeah, The targeting software needs a lot of work. :)
[02:20:43] <A-L-P-H-A> ?
[02:22:49] <Phydbleep> We hit the neighbors dog and took out a window at 7-11, but we missed you. :)
[02:23:02] <A-L-P-H-A> sounds like fun
[02:23:32] <Phydbleep> Beer does not aid in target aquisition..
[02:24:14] <punk84> punk84 is now known as punk84_afk
[02:24:17] <A-L-P-H-A> looks, like I'm gonna need a highspeed spindle anyways now, to do engraving.
[02:24:23] <A-L-P-H-A> for this damn product.
[02:24:26] <Phydbleep> BBL.. Off to the store for food.
[02:24:58] <Phydbleep> A-L-P-H-A: Isn't that the way it always works? "OK.. Now I need X to do Y.. "
[02:25:34] <A-L-P-H-A> well, I had X to do Y. But this new thing needs X do to Z.
[02:25:41] <A-L-P-H-A> or W to do Z.
[02:25:49] <A-L-P-H-A> as X isn't required.
[02:39:57] <Jymmm> http://www.gotmilk.com/news/news_040.html
[08:44:52] <Phydbleep> Woohoo! I knew I saved this hunk of junque for a reason!
[08:45:37] <Phydbleep> * Phydbleep is looking at a surplus Endevco accelerometer
[08:46:47] <Phydbleep> Accelerometer + encoder + geared up drive motor == High speed balancer. :)
[08:52:55] <Phydbleep> Sure beats the hell out of a 1972 set of 1300cc VW ignition points for a sensor. :)
[09:25:53] <Phydbleep> Just so "I" dont forget. :)
[09:25:59] <Phydbleep> logger_aj: bookmark
[09:26:00] <Phydbleep> See http://193.226.12.129/irc/irc.freenode.net:6667/emc/2005-04-29#T09-25-59
[10:13:52] <fenn> Phydbleep, why the hell do you need a balancer anyway
[10:21:23] <Phydbleep> fenn: Because I want to build a few things that will rotate at high velocity?
[10:22:01] <fenn> yes, of course, but what?
[10:23:08] <Phydbleep> Gas turbine parts, impellers, Parts for a couple of projects and an experiment or two..
[10:23:31] <fenn> cool that's what I was hoping... i'm planning on building some gas turbines too
[10:24:51] <Phydbleep> * Phydbleep is hoping to balance at 50K RPM to run at 50-70K RPM.
[10:26:27] <Phydbleep> Hehehe.. 3/4 HP, 1725 rpm motor with a ~26:1 gearup ought to deliver ~50K
[10:26:44] <fenn> pulleys?
[10:27:16] <Phydbleep> Yeah, I'll make a step pulley so I can walk the speed up as I get it balanced.
[10:28:11] <Phydbleep> I'll start at 1:1, then 5:1, 10:1, etc..
[10:29:12] <fenn> tesla had a special turbine case that allowed for grinding on the turbine while applying air to spin it up.. automatically balances the turbine at that rpm
[10:29:46] <Phydbleep> Yeah, I've seen that.. It only works with the bladeless disks though.
[10:30:02] <fenn> how does one balance a bladed turbine?
[10:30:10] <Phydbleep> Carefully?
[10:30:15] <fenn> i mean, where do you remove metal from?
[10:31:44] <Phydbleep> Well... if you started out right and balanced the disk, then weighed/matched the blades all you should have to do is a little filing on the edge of the disg or if you want a siren drill a hole. :)
[10:32:53] <Phydbleep> The Tesla balanccer will bend the bldes if you try it with a bladed disk..
[10:32:59] <Phydbleep> blades
[10:33:22] <fenn> i was under the impression that a lot of turbines were one piece cast construction
[10:34:04] <Phydbleep> Depends on the turbine.. Some are one-piece, some are assembled from disks/buckets.
[10:34:33] <Phydbleep> The spot welded blades are a bit scarey looking. :)
[10:34:57] <fenn> hmm only multi part turbines i've seen were held together with centrifugal force
[10:35:24] <Phydbleep> These are little ones for models/hobby stuff.
[10:35:54] <Phydbleep> I'm moe interested in the Tesla designs myself.
[10:36:01] <fenn> yeah me too
[10:36:14] <fenn> maybe that's because of the wild claims surrounding it
[10:36:27] <fenn> but also because it's more resistant to temp. cycling
[10:37:45] <Phydbleep> * Phydbleep is going to use heavy stainless for all the moving bits to eliminate warpage and to provide a decent scatter-shield..
[10:38:29] <fenn> for a tesla turbine or bladed turbine?
[10:38:34] <Phydbleep> Tesla.
[10:39:10] <Phydbleep> I've got an 11x60 lathe.. I can make a hell of a stack. :)
[10:39:27] <fenn> have you seen the patent in the 1980's about increasing cross sectional area between discs as you near the center?
[10:40:45] <Phydbleep> I htink so.. I remember something about a patent that took advantage of the gas expansion in a Tesla system.
[10:40:58] <fenn> i'm trying to think of ways to do that without making it either 1) too piggy or 2) explode from centrifugal stress
[10:41:14] <Phydbleep> define 'piggy'
[10:41:26] <fenn> so much gyroscopic force that the bearings fail
[10:41:31] <Phydbleep> sluggish responding to the throttle?
[10:41:35] <fenn> and sluggish
[10:42:02] <fenn> sluggish isn't so much of an issue depending on the application
[10:42:03] <Phydbleep> Ahh... No throttle on this one... Full Scream Baby! :)
[10:42:44] <fenn> i'm planning on starting with teeny tiny motors ala steve redmond
[10:43:07] <Phydbleep> ~6" here for the first ones. :)
[10:43:40] <fenn> how long have you been wanting to make one?
[10:43:53] <Phydbleep> 0.045 stainless for the disks and 1/2" wall pipe for the sctter-shield.
[10:43:56] <fenn> i've been scheming since at least '99
[10:44:07] <Phydbleep> 1979?
[10:44:12] <fenn> wow
[10:44:27] <Phydbleep> I think.. It was quite a while ago.
[10:45:45] <fenn> i wanted to put an allison 250 in my honda civic and started to do research on turboshaft engines
[10:46:10] <Phydbleep> I was working for a OMC dealer at the time and liked the new Wankel they were pushing but thought it was too much mass moving in the wrong directions. :)
[10:46:31] <fenn> heh a wankel isn't a rotary engine it's just a triangular piston engine
[10:46:47] <fenn> maybe a six-trochoid wankel would be balanced :)
[10:47:29] <Phydbleep> * Phydbleep does not want to see a piston doing figure 8's inside the crankcase..
[10:48:07] <Phydbleep> Or a Spirograph imitation.. :)
[10:48:51] <fenn> it's really pretty sad that there's not even one commercial turbine powered car
[10:49:08] <Phydbleep> Hehehe... There's a nut-bar here in town that sticks jets in everything. :)
[10:49:17] <fenn> cool
[10:49:24] <fenn> my kind of wingnut
[10:49:55] <fenn> where does he get them?
[10:50:13] <fenn> i went all over the southwest looking for small turbinee engines.. no luck
[10:50:48] <Phydbleep> http://www.unitednuclear.com/jetplans.htm
[10:51:19] <Phydbleep> http://www.unitednuclear.com/jetcars.htm
[10:51:30] <Phydbleep> There's the right page. :)
[10:52:41] <fenn> somehow i find that hard to swallow
[10:52:49] <Phydbleep> I love the "STAY CLEAR" license plate frame right under the exhaust on the CRX..
[10:53:23] <fenn> damn! he beat me to it by
[10:53:23] <fenn> ]
[10:53:27] <fenn> years
[10:53:39] <fenn> i give up
[10:54:04] <Phydbleep> He had a pulsejet on a Schwinn too. :)
[10:54:26] <fenn> rofl.. 0-300 in 4.9 seconds
[10:55:42] <Phydbleep> I think this is the same Bob Lazar that claims to have worked on UFO crap at Area-51.
[10:57:25] <Phydbleep> I do know there's some really WIERD SH*T goes on out in the desert south of town (toward White Sands) at night sometimes..
[10:58:13] <fenn> how could i have missed this website?
[10:58:50] <Phydbleep> Hehehe.. And the BIG laser power supply over at Sandia labs gives off some really strange effects in a thunderstorm..
[11:00:42] <Phydbleep> * Phydbleep has seen sodium vapor streetlights add just enough energy to make the atmosphere lase in the ultraviolet on that side of town...
[11:01:05] <fenn> hmmmm
[11:01:26] <fenn> i'm not really up on my laser theory
[11:01:30] <Phydbleep> They only did that once.. Too many complaints from people who were seeing purple spots..
[11:01:48] <Phydbleep> 3 days later.. :)
[11:03:18] <Phydbleep> The nitrogen in the air was ionized to just below the kickover point.. The UV from the sodium lamps added enough energy to make it superradiant.
[11:04:22] <Phydbleep> They learned to shut down the big power supply when a thunderstorm was coming in after that.
[11:07:25] <Phydbleep> Sorry.. Not sodium lamp.. Mercury vapor.. They've been swapping the Hg's out for the last few years.
[11:07:47] <fenn> i found some mercury vapor lamps in the dumpster today
[11:08:03] <fenn> need to read up on how they work
[11:08:11] <Phydbleep> Woohoo! Suntan, skin cancer and retinal damage. :)
[11:08:16] <fenn> funny thing is, that was at the grocery store dumpster
[11:08:25] <fenn> hey man plants love UV
[11:08:38] <fenn> kills the mold that attacks the bottom of the stem in seedlings
[11:09:02] <Phydbleep> New laws are that Hg's are going to be verboten here due to light pollution..
[11:09:19] <fenn> in NM or the whole USA?
[11:10:13] <Phydbleep> I had to show the neighbors the fluorescent bulb from my yard light to keep them from reporting me to the city..
[11:10:52] <fenn> gee he's selling mass-spec tested samples from the trinity site for $40 and claims that they are expensive
[11:10:56] <Phydbleep> Albuquerque for sure.. Not sure about out in the boonies..
[11:14:42] <fenn> you could buy a 108 LED UV lamp from unitednuclear and put it up there to piss them off
[11:15:02] <fenn> i can't even imagine a possible use for that thing
[11:16:30] <Phydbleep> Scorpion hunting. :)
[11:17:00] <Phydbleep> They glow real nice with a good UV source.
[11:18:06] <fenn> wow i think i could spend a lot of money at this website
[11:18:23] <Phydbleep> You could also give someone a suntan.. Though a wall or two. :)
[11:18:32] <Phydbleep> through
[11:19:06] <fenn> LED's arent high enough energy photons to burn you
[11:20:40] <Phydbleep> I wouldn't want to bet on that.. 108 of the 390nm's is a lot of UV..
[11:23:09] <Phydbleep> Hehehe... one of those and a cylinder of the uv flourescent acrylic for a hell of a fake laser show
[11:25:46] <Phydbleep> I'm annoyed at their phosphoescent powder though.. It didn't survive a trip through a cone-6 kiln as a glaze ingredient. :\
[11:26:49] <fenn> gee i wonder why
[11:27:44] <Phydbleep> They assured me it would.. "Oh, Sure.. Just keep it under 2500F and it'll be fine".. NOT..
[11:28:18] <fenn> was it electric or gas fired kiln? cause reducing atmosphere can do weird things sometimes
[11:28:31] <Phydbleep> Tried both.. No go.. :\
[11:28:37] <fenn> shrug
[11:29:06] <fenn> can you mix it with powdered soda glass?
[11:29:14] <Phydbleep> Even tried running one through the soda kiln.. Same lack of glow afterwards.
[11:29:32] <fenn> epoxy it is then
[11:30:32] <Phydbleep> Nope.. Just no glowing ceramic glazes.
[11:32:48] <Phydbleep> Hmm... 05:30.. Time to rewire the "snooze" button for "self-destruct" so I can get some sleep...
[11:33:45] <fenn> just snort some m-state powder and you won't have to sleep
[11:34:55] <Phydbleep> I'd rather have sex with a tree chipper..
[11:35:16] <Phydbleep> * Phydbleep does not play with powders.
[11:36:09] <Phydbleep> * Phydbleep is the kind of sick puppy who leaves a line of Ajax on the edge of the sink..
[11:36:50] <fenn> yeah but m-state is superconducting. it quantum tunnels through your skin
[11:36:55] <Phydbleep> Do that in a bar and wait for the screams of pain.
[11:37:11] <fenn> do what, have sex with a tree chipper? :)
[11:37:38] <Phydbleep> No.. The Ajax on the sink..
[11:38:16] <Phydbleep> Worry if you hear screams then "Smmooooth!.."
[11:38:39] <fenn> * fenn raises his eyebrow.
[11:39:21] <Phydbleep> People will snort all kind of funny powders laying on the edge of the sink in a neat line. :)
[11:40:04] <Phydbleep> Even if they have "no clucking foo" aboout what they are/where they came from..
[11:41:29] <Phydbleep> 50% of this town is burnouts and the rest of us are having too much fun playing practical jokes on them to develop a drug habit. :)
[11:43:44] <fenn> sounds like a fun place to spend your winters
[11:44:31] <Phydbleep> Beats sitting on the street corner with a stack of score-cards waiting for a wreck. :)
[11:45:08] <Phydbleep> Ehh.. You get a 3.2 for the collision, but a 9.5 for screaming at the cop. :)
[11:45:18] <Phydbleep> Hehehe.. :)
[11:45:28] <fenn> what's a perfect 10?
[11:45:37] <Phydbleep> Rear-ending the cop. :)
[11:45:53] <Phydbleep> Seen a couple of those here too.
[11:47:32] <Phydbleep> My favorite practical joke on motorheads is catch one at a light who doesn't notice the cop pull in behind him, floor it when the light goes green and hit the cruise control at 30. :)
[11:48:28] <Phydbleep> Doen't matter who it is 99% of the time they floor it too and keep it there till the cop lights them up. :)
[11:55:56] <fenn> If you really need an unbelievably powerful magnet, here it is.
[11:55:56] <fenn> Uses include magnetic steering of nuclear particles in homemade accelerators, magnetic beam amplifiers, etc.
[11:55:56] <Phydbleep> 06:00.. Time to fall over. Laters all. :)
[11:56:26] <fenn> 'night
[14:15:11] <Jymmm> G'Morning Folks!
[16:09:33] <Prius> Prius is now known as TurkiyeLee
[17:45:14] <robin_sz> ahh, meep!
[17:52:49] <les> hi robin
[17:52:55] <robin_sz> dood!
[17:53:00] <alex_joni> hey les
[17:53:04] <alex_joni> meep?
[17:53:09] <les> first cut at publishing this site
[17:53:13] <les> have a look?
[17:53:18] <robin_sz> you have paul_c there yet?
[17:53:27] <robin_sz> les, sure ... fire away
[17:53:30] <les> not yet...early next week
[17:53:38] <robin_sz> * robin_sz nods
[17:53:58] <les> http://www.broderickcrawfordart.com/index.html
[17:54:38] <les> I could not use oscommerce...ipowerweb has some problems and are working on it
[17:55:06] <les> have not set up the store yet anyway
[17:55:09] <alex_joni> robin: does this make any sense to you?
[17:55:21] <alex_joni> a pal of mine uses a network connection
[17:55:34] <alex_joni> static IP (real)
[17:55:47] <alex_joni> but the GW is in a different subclass
[17:56:02] <alex_joni> works on doze, doesn't on linux
[17:56:28] <robin_sz> subnet
[17:56:39] <robin_sz> errm
[17:56:49] <robin_sz> that doesn make any sense whatsoever
[17:57:03] <robin_sz> define "differetn subnet"
[17:57:28] <robin_sz> see.. byt "different subnet" it generally means you have to go through the default gw to get to it ...
[17:57:52] <robin_sz> which if the default gw is on the different subnet would be err, unreachable
[17:58:06] <alex_joni> Network Destination Netmask Gateway Interface Metric
[17:58:06] <alex_joni> 0.0.0.0 0.0.0.0 194.153.227.187 80.97.145.121 20
[17:58:06] <alex_joni> 10.0.0.0 255.255.255.0 10.0.0.101 80
[17:58:21] <robin_sz> I suspect the gw is actually on the same lan segment right?
[17:59:06] <alex_joni> I don't know ;)
[17:59:17] <alex_joni> but I found it very odd.. to say the least
[18:00:36] <robin_sz> could work
[18:01:13] <robin_sz> 80.97.145.121 is his local IP on his ADSL I guess
[18:01:23] <alex_joni> not adsl
[18:01:30] <alex_joni> but his local ip, right
[18:02:35] <alex_joni> the second one is also very odd
[18:02:39] <robin_sz> yep
[18:02:46] <alex_joni> 10.x.x.x should be class A
[18:02:47] <robin_sz> well no
[18:03:01] <alex_joni> can be used as C
[18:03:05] <robin_sz> you dont have to use an A class
[18:03:10] <robin_sz> yep
[18:03:17] <robin_sz> so .. it the first one,
[18:03:20] <robin_sz> crazy
[18:03:38] <alex_joni> in linux it won't let you add that route
[18:03:46] <robin_sz> dotn blame it
[18:04:02] <alex_joni> I don't
[18:05:07] <robin_sz> route add default gw 194.153.227.187 dev eth1
[18:05:26] <robin_sz> (or wherever his 80.97.145.121 is bound to)
[18:05:27] <alex_joni> doesn't work
[18:05:41] <alex_joni> says it's on a different SUBNET
[18:05:46] <robin_sz> right
[18:05:58] <robin_sz> thats also true .. but a different subnet to what?
[18:06:00] <alex_joni> can't remember the exact words, but that's what it says
[18:06:04] <robin_sz> yeah
[18:06:10] <alex_joni> to the local ip/netmask
[18:06:13] <robin_sz> seriusly fucked up routing
[18:06:22] <alex_joni> so it's not reacheable
[18:06:33] <robin_sz> that what id have thought
[18:06:45] <alex_joni> les: about doesn't work
[18:07:06] <les> oh it's just a first cut
[18:07:13] <robin_sz> thats what you need a gw for .. to get from this subnet to that subnet .. and if the gw is not on the subnet, you am fuxxored
[18:07:14] <les> lots do not work yet
[18:07:21] <les> have not put in the links
[18:07:24] <robin_sz> les: anyway, looks arty :)
[18:07:53] <alex_joni> heh
[18:08:04] <les> that shadow effect is from photofiltre....pretty neat for a free program
[18:08:32] <robin_sz> les: comments? the black text in the purple boxes need to be the same height and weight and anti-aliased, looks a bit rough at the moment
[18:08:47] <les> yeah I know
[18:08:51] <les> good point
[18:08:56] <robin_sz> and dont do your floating trext images like you have
[18:09:09] <robin_sz> the http://www.broderickcrawfordart.com/geometry/obj296title292shd9pg1p2.png
[18:09:27] <robin_sz> rather than using the background as a , err, background
[18:09:43] <robin_sz> use text over transparent
[18:10:13] <robin_sz> anti-alias the text edges with a vaguely similar colour to the background
[18:10:13] <les> well the backgroungd is tiled
[18:10:19] <robin_sz> yeah, I know
[18:10:20] <les> which page is that on?
[18:10:24] <robin_sz> fron
[18:10:25] <robin_sz> t
[18:11:12] <robin_sz> ick and dont ever do font size in pixels :)
[18:11:40] <les> looks ok from here. What's the problem you see?
[18:11:53] <robin_sz> with?
[18:12:00] <robin_sz> fonts in pixels?
[18:12:10] <les> with obj296
[18:12:21] <robin_sz> its text over a background ...
[18:12:31] <les> yeah...
[18:12:38] <robin_sz> thats generally not how its done
[18:12:41] <les> partly transparent
[18:12:57] <les> oh sitespinner did that
[18:12:58] <robin_sz> why not a fully transparent background?
[18:13:03] <les> is there a better way?
[18:13:28] <robin_sz> imagine you want to change the bg image .. even just its tone or hue
[18:13:43] <robin_sz> you cant without remaking all the images for the text right?
[18:14:15] <les> ah...can't seem to make the background transparent in sitespinner
[18:14:22] <les> would have to write code
[18:14:52] <robin_sz> if you do the text images as text over transoparent, you can use different bg in a snap, or if the bg image doesnt load, the site still looks OK
[18:14:53] <les> what browser are you using?
[18:15:00] <robin_sz> mozilla
[18:15:09] <les> ok
[18:15:24] <robin_sz> remember, many people with bad eysight will turn off bg images anyway
[18:15:39] <les> must look different in mozilla
[18:15:56] <robin_sz> oh, and the link images have no alt text
[18:16:00] <les> seems pretty smooth in ie
[18:16:18] <les> yup alt text is on my list!
[18:16:36] <robin_sz> finally, fonts sized in pixels is deeply bad
[18:16:43] <les> hmmm
[18:16:51] <les> ok if you say so
[18:16:53] <robin_sz> one of the worst useability sins going
[18:17:16] <les> again it was just what sitespinner did
[18:17:43] <robin_sz> remember they will appear the same number of pixels in a 640x480 and a 1600x1200 display
[18:17:57] <alex_joni> robin: wanna hear some more?
[18:18:11] <les> It's one of those things where I must give them a VERY easy to use software so they can manage it themselves
[18:18:15] <robin_sz> plus, it prevents people with impaired vision from varying the size with their mouse wheel
[18:18:29] <les> but it may compile poor code
[18:18:31] <robin_sz> well, you asked for my comments :)
[18:18:42] <les> let me check if I have options with that
[18:18:51] <les> good comments
[18:18:55] <robin_sz> finally, run it through validator.w3.org :)
[18:19:23] <alex_joni> robin: imagine that that gw is actually the providers primary ns
[18:19:50] <les> ok only does pixels
[18:19:55] <les> oh well
[18:20:22] <les> "best viewed with 1024x768" heh
[18:21:04] <les> there still might be an option somewhere though
[18:21:12] <robin_sz> well, thats a shame, it will upset anyone with imparied wision who is used to using ctrl-scroll to change text sizes
[18:21:13] <les> only had the program 1 day
[18:21:31] <robin_sz> seems to produce valid html, thats a rarity these days
[18:21:43] <les> I will ask about that on their support group
[18:22:06] <robin_sz> I should imagine that a number of the potential clients are in the "silver surfer" category
[18:22:10] <Jymmm> it's an art page, I doubt the target audiance is someone vision impared
[18:22:36] <robin_sz> shrug
[18:23:01] <robin_sz> anyway, fonts in pixels is just such a bad bad bad thing,
[18:23:32] <les> yes it will look screwy in anything other than 1024 768
[18:23:45] <robin_sz> im in 1600x1200 here
[18:23:45] <Jymmm> that's what alt tags are for
[18:24:02] <les> heh
[18:24:21] <robin_sz> and ...
[18:24:28] <Jymmm> les that would be my only bitch... fixed resolution
[18:24:44] <alex_joni> les: http://www.nedstatbasic.net/s?tab=1&link=5&id=2071331
[18:24:48] <robin_sz> Jymmm: strangely, text doesnt have alt tags and its text that is set by the font sizes
[18:25:05] <robin_sz> ah, and the big drop off
[18:25:28] <Jymmm> robin_sz I thought you were talking about the gephic text.
[18:25:28] <robin_sz> once you click on a page, its a dead end
[18:25:44] <robin_sz> Jymmm: nope, thats set in images, not fonts
[18:26:17] <Jymmm> Oh fixed font sizes
[18:26:26] <robin_sz> yes, in pixels
[18:26:51] <Jymmm> looking at source now.... UG-LEE (css wise)
[18:27:24] <les> I hacked the css a bit
[18:27:35] <les> that is only for the gallery stuff
[18:27:51] <Jymmm> 85000 div id tags
[18:27:51] <robin_sz> yeah, weird that it defiens soem style elements, then expllisitly uses styles in the layout
[18:28:16] <robin_sz> thats OK, thats justthe way things are
[18:28:27] <les> I had a gallery software batch process the images....but did not use the pages it created
[18:28:42] <les> just the thumbnail and big images
[18:28:43] <robin_sz> anyway, navigation needs to be consistent
[18:28:46] <robin_sz> no dead ends
[18:29:11] <les> yeah I have not put links back on most of the pages yet
[18:29:23] <robin_sz> oh and "Select one of the three artwork categories below" is not centred under categories
[18:29:24] <les> just a first cut
[18:29:30] <robin_sz> by quite a way
[18:29:31] <robin_sz> heh
[18:29:32] <Jymmm> Love the border = 0
[18:29:44] <les> let me look
[18:29:49] <robin_sz> well, you asked for comments :)
[18:29:54] <robin_sz> artwise it looks nice
[18:30:27] <les> oops I didn't center that heh
[18:30:29] <Jymmm> too many div id= tags though
[18:30:43] <les> well the festival is tommorrow
[18:30:56] <les> wanted something up
[18:31:03] <les> will fix it later
[18:31:03] <robin_sz> yeah
[18:31:30] <Jymmm> les dont let robin_sz's microscope scare you away =)
[18:31:32] <les> this whole thing is about 4 hours in working on it so far
[18:31:34] <robin_sz> artwise it looks nice
[18:31:52] <robin_sz> the background and the drop shadows work nicely for me
[18:32:01] <les> well, I need to hire a kid to do this.
[18:32:11] <les> I shouldn't be heh
[18:32:25] <les> well it's just for my uncle
[18:32:38] <robin_sz> ?
[18:32:41] <les> and I only charged him a kilobuck.
[18:32:43] <Jymmm> les Be sure to put navigation on EVERY page, in case someone come sto the site from a link.
[18:32:47] <robin_sz> but family always deserve the best right?
[18:33:03] <les> no. hahaha
[18:33:12] <robin_sz> I was having fun on the laser today
[18:33:18] <robin_sz> cutting stainless
[18:33:29] <robin_sz> with high pressure nitrogen
[18:33:37] <les> Hey I'm an engineer...for a kilobuck I can only work on this for 10 hrs!
[18:33:38] <les> haha
[18:34:26] <les> Well thanks for the comments. I have to go to town and set some festival stuff up.
[18:34:31] <les> bbl
[18:34:31] <robin_sz> right
[18:34:38] <robin_sz> its actually quite nice
[18:34:46] <robin_sz> but well you asked ;)
[18:34:47] <les> hehe
[18:35:03] <les> well it's perfect except for the bad bits.
[18:35:10] <robin_sz> yes
[18:35:14] <les> haw
[18:35:15] <robin_sz> well .. mostly
[18:35:16] <les> later
[18:35:22] <Jymmm> later les
[18:35:48] <robin_sz> so .. having taken les' html skills apart ...
[18:36:06] <robin_sz> time to continue taunting Jymm about ERP and antennae
[18:36:39] <Jymmm> robin_sz 100 watt radio + antenna =< 100 watt
[18:36:49] <robin_sz> 100 watt ERP?
[18:36:59] <Jymmm> tha't NOT what I said
[18:37:06] <robin_sz> what did you say?
[18:37:29] <Jymmm> exactly that three lines up
[18:37:38] <robin_sz> well, it doesnt mean anything
[18:38:04] <alex_joni> it does.. kinda
[18:38:13] <robin_sz> 100 watt radio = 100 watts pTot
[18:38:17] <alex_joni> 100 watt transmiter
[18:38:33] <robin_sz> 100 watts radio + 3db antennae = 200watts ERP
[18:38:34] <alex_joni> + antenna ->under 100 watt (because of losses)
[18:38:45] <alex_joni> but no one cares about output power
[18:38:57] <robin_sz> and many bands (most even?) are erp limited
[18:39:00] <alex_joni> they care about ERP (or EIRP)
[18:39:07] <robin_sz> and its erp that counts for signal stregth
[18:39:12] <alex_joni> right
[18:39:21] <robin_sz> and its erp that limits the output of wifi cards
[18:39:36] <alex_joni> you can have 50 mW (common on wifi)
[18:39:44] <alex_joni> and the limit is at 100mW
[18:39:51] <robin_sz> actually .. it can be more
[18:39:56] <alex_joni> 50mW=17dBm(IIRC)
[18:39:59] <robin_sz> up to 1w
[18:40:03] <Jymmm> Ok, wifi is the ONLY restriction I've ever seen that has an antenna restriction.
[18:40:10] <robin_sz> bullshit
[18:40:11] <alex_joni> not in 2.4
[18:40:22] <Jymmm> Ok, wifi is the ONLY time I've ever seen that has an antenna restriction per the FCC Rules
[18:40:27] <robin_sz> you never read your ham regs then
[18:40:27] <alex_joni> 2.4 limit is 20 dB
[18:40:50] <alex_joni> even arecibo has an ERP limit
[18:40:55] <robin_sz> yep
[18:41:03] <alex_joni> it's some MW's
[18:41:06] <alex_joni> lol
[18:41:12] <Jymmm> robin_sz it's an unlicensed band
[18:41:23] <robin_sz> no such thing
[18:41:32] <Jymmm> CB
[18:41:37] <robin_sz> like i said
[18:41:40] <robin_sz> no such thing
[18:41:48] <robin_sz> unlicensed .. hah
[18:41:54] <robin_sz> it is very licensed ...
[18:42:06] <alex_joni> there are some bands you don't need to buy a licence
[18:42:16] <alex_joni> but.. licence exists
[18:42:18] <robin_sz> you cant run a MW on 27mhz under the terms of the licence
[18:42:21] <robin_sz> exactly
[18:42:28] <robin_sz> even wifi is licensed
[18:42:42] <Jymmm> robin_sz quit being a pita... you know what I mean!
[18:42:47] <robin_sz> in that so long as it complies with t apec, you dont have to buy one
[18:43:23] <robin_sz> well, you were the one that told me I knew jack shit about comms
[18:43:30] <robin_sz> and you dont even knwo what erp is
[18:44:12] <alex_joni> it's eirp afaik
[18:44:18] <Jymmm> robin_sz No, I wasn't talking erp, you were.
[18:44:23] <alex_joni> thekey beeing isotropic
[18:44:30] <robin_sz> in fact .. i think you said something like "an antennae cant make it illegal there is no FCC restriction on any antennae"
[18:44:44] <Jymmm> That I did say
[18:44:49] <robin_sz> when infact, the very opposite is true
[18:44:53] <Jymmm> other than height for FAA stuff
[18:44:58] <robin_sz> nope
[18:45:23] <alex_joni> Jymmm: on 2.4 wifi you have a limit of 20dB
[18:45:32] <alex_joni> if your card does 17 dBm
[18:45:36] <robin_sz> if you get a licence for a radio station, it will state maximum erp
[18:45:45] <alex_joni> and your antenna - losses = 3dBi
[18:45:45] <robin_sz> many of the ham bands do too
[18:45:57] <alex_joni> then you have 17+3=20dB
[18:46:01] <alex_joni> shouldbe ok
[18:46:05] <robin_sz> alex_joni: actually, wifi is more complex than that ...
[18:46:29] <alex_joni> but if you have an 20dBi antenna.. you arecertain to exceed that value of 20dB
[18:46:39] <robin_sz> for each 3db over 16db of antennae gain, you only subtract 1db from the tx power
[18:46:47] <robin_sz> its aweird
[18:46:48] <robin_sz> one
[18:46:50] <alex_joni> robin: I know, was only keeping it simple
[18:47:00] <robin_sz> yeah, ok
[18:47:10] <alex_joni> and you might connect your high gain antenna to tx
[18:47:12] <alex_joni> rx
[18:47:16] <robin_sz> im just suprised Jymm has never read his ham regulations
[18:47:17] <Jymmm> do you really think I'm going to alter the design of an antenna, or tweek the tranmitter?!
[18:49:11] <Jymmm> "Oh no, this antenna is desgined too well , let me use a shitty antenna instead so I cna be legal" I don't think so
[18:49:27] <robin_sz> no of course I dont ...
[18:50:33] <robin_sz> "Ok, wifi is the ONLY time I've ever seen that has an antenna restriction per the FCC Rules" ...
[18:50:51] <alex_joni> Jymmm: there are antennas out there which in combination with amps are illegal
[18:51:06] <alex_joni> that is if you don't set transmit power accordingly
[18:51:25] <Jymmm> alex_joni Di I say antenna + tx? No, I said antenna. There is no such thing as an illegal antenna.
[18:51:55] <Jymmm> think swap meet... you can't buy an illegal antenna.
[18:51:57] <robin_sz> Jymmm: OK, can I ask you .. whats the power linit on 60M band in the USA?
[18:52:01] <alex_joni> of course there isn't, only using it makes it illegal
[18:52:31] <alex_joni> I can have a 200W amplifier for 2.4 in my backyard
[18:52:40] <Jymmm> robin_sz I'l only a tech, so I'll say 1500 PEP
[18:52:43] <alex_joni> switching it on makes it illegal
[18:52:52] <robin_sz> Jymmm: nope, 50w ERP
[18:52:53] <Jymmm> alex_joni no it doesn't
[18:53:34] <alex_joni> how come?
[18:53:41] <Jymmm> I dont know about you guys, but my radios have a power level switch
[18:54:20] <Jymmm> besides, you are suppose to run lowest power to maintain communications.
[18:54:32] <robin_sz> well, thats one view
[18:54:42] <robin_sz> the other is that its rude to be weak ;)
[18:54:48] <alex_joni> lol
[18:55:04] <alex_joni> turn the m into M
[18:55:26] <Jymmm> that would be CBers then, you a CBer robin_sz ?!
[18:55:30] <alex_joni> even G
[18:55:43] <robin_sz> feck no
[18:55:44] <alex_joni> he-s a HAMer
[18:55:49] <alex_joni> right?
[18:56:05] <robin_sz> might be ;)
[18:56:22] <robin_sz> I used ot do a fair bit of vhf contesting
[18:56:55] <robin_sz> thats sort of knowing the rules, and then breaking them to hell and back :)
[18:57:58] <Jymmm> http://www.ce-mag.com/archive/1999/julyaug/case.html
[19:00:22] <robin_sz> and?
[19:01:50] <alex_joni> heh 6dB antennas
[19:01:51] <alex_joni> and 17dBm emitters
[19:01:55] <alex_joni> not very much
[19:02:19] <robin_sz> 17dbm on 5.7 is not trivial
[19:02:53] <robin_sz> I have a 10w twt on 10G ...
[19:03:02] <robin_sz> but its such a pita ...
[19:03:27] <robin_sz> I ahave a 7w solidstate brick on 13ghz I want to down-tune
[19:04:32] <robin_sz> ooh, this taunting Jymm is fun, I should have doen it before ;)))
[19:04:56] <Jymmm> robin_sz when you figure out how to alter a pager to run ARPS instead of POCSAG, let me.
[19:05:11] <Jymmm> know
[19:05:33] <robin_sz> im sure its been done
[19:05:58] <robin_sz> a friend of mine built some very neat pocsag logging gear
[19:06:13] <robin_sz> pete bear ...
[19:06:51] <Jymmm> Yeah, I've seen em. But I want a pager.
[19:07:08] <robin_sz> I wnat dancing girls
[19:07:14] <alex_joni> lol
[19:07:35] <Jymmm> then I can send stuff to it...
[19:07:45] <robin_sz> just send pocsag then
[19:07:45] <Jymmm> sports scores, weather, whatever
[19:08:04] <Jymmm> cant send pocsag over ARPS, the protocolos are incompatable.
[19:08:14] <Jymmm> (already looked into it)
[19:08:19] <robin_sz> well, why send it over arps?
[19:08:37] <Jymmm> I can be anywhere in the coutnry then
[19:08:53] <robin_sz> ermm, can pagers transmit?
[19:09:04] <Jymmm> No, but they can Rx
[19:09:16] <robin_sz> so.. exactly how will that work then?
[19:09:32] <robin_sz> arps is a bidirectional routed protocol
[19:09:46] <Jymmm> it's doesn't have to be bi directly
[19:09:57] <robin_sz> it need sot know where you are to route, and it needs an ack
[19:10:03] <Jymmm> you broadcast WX, that's not bi-directional
[19:10:15] <robin_sz> thats slightly special I guess
[19:10:31] <Jymmm> you broadcast your position, that's not bidirectional
[19:10:49] <robin_sz> well, it is at the rx end
[19:11:11] <Jymmm> If I dont want to ACK, that's fine.
[19:11:45] <robin_sz> well, I cant imagine the protocol will allow you to send your sports scores et to the entire country
[19:12:11] <robin_sz> that would make th enetire country one cell/channel
[19:12:18] <robin_sz> it woudl be full PDQ
[19:12:21] <alex_joni> I'll leave you guys to sort this out
[19:12:26] <alex_joni> night ;)
[19:12:27] <robin_sz> yeah
[19:12:33] <robin_sz> im bored now ..anyway
[19:12:40] <robin_sz> Jymm is too easy to wind up
[19:12:41] <robin_sz> ;)
[19:13:01] <robin_sz> must go and beat the wife and shoot the dog,
[19:13:05] <robin_sz> back later.
[19:13:19] <alex_joni> don't forget the kids...
[19:13:22] <alex_joni> too late
[19:16:10] <robin_sz> logger_aj bookmark?
[20:21:26] <les> well back from town
[20:21:42] <les> forcast for our spring festival: rain all day.
[21:26:52] <fifty_ohm> Anyone using axis as a frontend?
[21:36:49] <Phydbleep> les: I thought you were in GA not OR. :)
[21:38:05] <anonimasu> hey
[21:38:07] <anonimasu> how's it going?
[21:38:26] <Phydbleep> anonimasu: You talking to me?
[21:39:55] <anonimasu> I'yeah
[21:42:08] <les> now back from some mowing.
[21:42:16] <les> pollen is killing me though.
[21:43:23] <Phydbleep> I knew I saved some of this surplus crap for a reason.
[21:44:03] <les> and I have to work on the cars after the spring pollen...radiators...heater core...air filter...usually clogged
[21:44:28] <les> I have a good bit of surplus crap too
[21:44:39] <Phydbleep> I found the surplus Endevco accelerometer that I got a few years back and realised it would make a great sensor for a spin balancer. :)
[21:45:21] <Phydbleep> Accelerometer + encoder + geared up drive motor == High speed balancer. :)
[21:45:37] <les> what is it? a quartz tri beam type?
[21:46:00] <Phydbleep> With the addition of a scatter-shield and some frame it should be OK.
[21:46:10] <les> yeah
[21:46:33] <les> I have a dozen or two of those analog devices accels
[21:46:42] <les> got em as free samples
[21:46:50] <Phydbleep> Not a clew.. It's a little stainless cylender ~12mm D x 15mm L
[21:47:16] <les> well what does the output look like?
[21:47:22] <les> that will be a clue
[21:47:34] <Jymmm> logger_aj bookmark
[21:47:37] <Jymmm> logger_aj, bookmark
[21:47:37] <Jymmm> See http://193.226.12.129/irc/irc.freenode.net:6667/emc/2005-04-29#T21-47-37
[21:47:38] <Phydbleep> Jymmm: And what in the hell do you want???? <JK> :)
[21:48:11] <Phydbleep> Jymmm: Forget it she's mine. :)
[21:48:22] <les> oh I imagine the code fest thing is over huh
[21:48:34] <Phydbleep> Hehehe... By the time he figures that out I should be long gone. :)
[21:49:09] <Phydbleep> les: They are an analog out.. I was using the adc on a pic to read it before.
[21:49:10] <Jymmm> Phydbleep You can have the ewe, I'm not into beastiality
[21:49:21] <les> hmm ok
[21:49:32] <les> quartz usually needs a charge amp
[21:49:47] <Phydbleep> Jymmm: They trusted ewe.. :)
[21:50:44] <Phydbleep> This was a straight analog signal.. I could yell at the accelerometer and get a reading. :)
[21:51:08] <Jymmm> Phydbleep did you do the acetone thing yet?
[21:51:25] <les> I have some b&k impedance heads somewhere
[21:51:36] <Phydbleep> I think it is a real old one from Sandia or White Sands.. They use a lot of them for vibration detection in engines/equipment.
[21:51:37] <les> accel+load cell
[21:51:42] <les> kinda handy
[21:52:50] <Phydbleep> Jymmm: Not yet, need to pick up a 'brayer' (Ink roller) for burnishing it down. :)
[21:54:30] <Phydbleep> I've did a similar proces on glass with photo stuff years ago and got good at getting the image sealed down without distortion or bubbles..
[21:59:16] <Jymmm> I think if you just make a snadwich, you'll be fine.
[21:59:26] <Jymmm> instead of needing a roller.
[21:59:39] <Jymmm> acetone loves to dry out rollers
[22:00:30] <Jymmm> doesn't effect PET though
[22:00:35] <Phydbleep> I want to be able to get all the bubbles out and the roller is an expendable item..
[22:01:17] <Jymmm> get it laser marked into annozied aluminum
[22:01:22] <Phydbleep> Plus I have a sheet of teflon film to lay over the parts to protect the roller. :)
[22:02:02] <Phydbleep> Jymmm: Anodize some transparent aluminum for me and I'll try it. :)
[22:02:23] <Jymmm> oh your not doing reflective?
[22:02:48] <Phydbleep> Transmissive.. It's the only way the pwm band will work.
[22:04:10] <Jymmm> ah
[22:05:50] <Phydbleep> I'll have ~ 2x the thickness of the acetate between the pattern and the sensor. Acrylic> pattern < Acetate < Air Gap.
[22:09:23] <Jymmm> how thick acrylic?
[22:10:10] <Jymmm> you wont have any issues with optical deflection?
[22:10:50] <Phydbleep> 1/8" for the test.. 3/64" (I think) for the 2nd test.
