you know, I'd almost switch the LiveCD to Ubuntu Gutsy just for this: http://people.ubuntu.com/~bryce/BulletProofX/
or, it may be possible to get it to work on 6.06
what number is gutsy? 7.10?
I think so
the next LTS release is 8.06 (or thereabouts), right?
yeah - Feisty / Gutsy
they just decided on the name, can't remember atm
too bad there isn't a new LTS
Feisty is out isn't it? 7.04 or whatever?
wonder what we should do for 2.2 (other than wait for april)
I don't think we really want to wait until April
hmmm. Feisty might have been 6.10
what is 2.2 still waiting for?
I wish the upload speed from here weren't so terrible. I can probably build CDs in prett short order, but getting them to the website is slow as death
me to get off my ass and finish the 5i20 stuff?
nope, that's not it :)
hmm, the ubuntu site doesn't use the names much
SWPadnos: making a new cd is so rare it doesn't matter how slow the upload is
they go by numbers only now
is there anything linking EMC2 versions to LiveCD versions?
no and afaic there never will be
seems we could release 2.2 in a couple months, and a new liveCD when the new LTS comes out
it's true that we could release for (just) dapper for now.
finally found it - Feisty is 7.04, the current rev, Gutsy Gibbon will be 7.10
yep -just seeing that now
I'm trying to find out what 8.04 will be called. I thought they had just announced it
"Note: The official way to refer to a released version of Ubuntu is by the number, not the name. Thus the current version of Ubuntu is 7.04, not Feisty Fawn."
Hardly Horny Heron
I hope 8.10 is called Inebriated Ibex
that's what I'd vote for
or is that a?
too bad they skipped C. Constipated Cobra would have been fun
(to go with the cobra)
and of course, Jabbering Jackass
so, assuming that I actually stop chatting and lay out this PCB, I'll be doing some Mesa work next week and the week after
SWMBO suggests Kicked-up Kangaroo
first thing is to get the 5i22 working for the "normal" 5i20 driver
"Kind Kipper" or something would be nice
jmkasunich, do you want a 5i22?
I was considering that
what I really want is to break my "writer's block"
heh - I'll help out with that inthe next couple of weeks as well, if I can
I have an SPI module from Pete W
maybe that would help
that should probably be added to the generic module list
a generic SPI module is gonna be hard to do
then I'll need to do the AD7656 and DAC5764-specific ones
well, it shouldn't be too hard to have separate SPIs. I think the module Pete sent over has clock, data, CS and something else (I think he said it's 4 lines)
oh duh, data in and data out
it has a register for the number of bits per word, up to 32
it uses the 40 MHz clock, and has a divide register as well
I have a couple A/D and D/A chips in mind too - 12 bitters, in tiny (SOT-6 IIRC) packages with pretty tiny prices
don't recall the numbers right now
(20 MHz max speed - need on up and one high cycle minimum per bit)
yep, the ASD1100 series
err - one high and one low cycle ...
also I want to do a simple 32 bit I/O expander, using shift registers
that should be trivial with the module I have
$0.25 chips in SO-20 packages
daisy chain the 4 chips, hook up CS, and go
actually, 8 chips - you can probably use the same clock to read back the inputs as you use to send the outputs (though I don't know that his module does full duplex - it should)
exactly what I had in mind
the only issue would be buffering the clock line without too muck clock skew
I don't care if his module does full dup or not, the I/O expander is a trivial bit of VHDL
especially with SPI done already ;)
I'd probably run it a no more than a couple MHz, so clock delays are a non-issue
yep. though the A/D could run into trouble
thats why I don't care about his SPI
I would use dedicated VHDL for each application
well, you can always block copy and change some parameters
its not like software where reusing code saves memory - gates will be needed regardless of whether you duplicate his module or use a dedicated on
I think the SPI block is just a clock divider and a couple of shift registers, plus a counter and count setting
heh - I think I hear Blue Oyster Cult starting
man. I am glad I live a mile from the fairgrounds
as opposed to two miles? or a quarter mile? ;-)
if I lived next door, I'd have to shoot someone
most of the concerts at the fair are country
instead of shooting, I'd recommend an axe to the power cord
wear rubber gloves
tonight is the Joan Jett / Foghat / Blue Oyster Cult concert that I considered going to, so it's not as bad
I briefly considered going to a concert this evening, but I'm a little toasted
about 5 hours outdoors at the airshow
ouch - that can be hard on the skin
I used sunscreen on arms and face, but forgot the back of my neck
"you might be a redneck if"
you forgot the sunscreen
yeah, I hate it when it feels like my entire body shriveled up
than after I got home and looked at pics, I went outside again and did some yard work - toteing and hauling
see. that's why I don't do yard work (when I can avoid it)
(which is often)
got one of these: http://www.thebagster.com/
I've been avoiding for years
I hate websites that won't show you where they have service - that only let you search by ZIP code
I've been wanting to get a dumpster for several years, but its a major pain - appointment for dropoff, limited time to fill it up, another appointment for pickup
the bag lets me buy it when I want, fill it over as long a period as I want, then call for removal
I never did get pricing for a dumpster
the bag is $30 to buy, and $99 to remove, for 3 yards
when my mother got one (a construction dumpste, so pretty big), it was ~$300 for the month - maybe $150 for a week, and that included delivery and removal
among other things, I have about 40' of split rail fence that was removed 10 years ago and has been rotting (too slowly) in a pile since then
per yard, she got a much better deal
but I don't need that much
hmmm. we have about 200 feet of fence rotting, standing in a straight line :)
the fence, a bunch of rocks, bricks, cinderblocks, etc
I really need to take the wheelbarrow (or at least its wheel) to the gas station and fill it up with air
that's what shop air is for
don't have shop air
oh. well, I can bring you a compressor next year if you like ;)
I carried 10-12 five gallon buckets of rocks from the back of the yard to the driveway where the bagster is
I have a compressor that I bought for cheap from a co-worker a while back
I think I'd have filled the wheelbarrow tire after about 2 buckets
it was cheap because it needed re-plumbed
which I haven't done yet
it was starting to get dark, and I knew if I stopped to fill the wheel it would be too dark to do anything when I got back
besides, a little excercise keeps me in shape
(or less out of shape anyway)
yep - taking a short break often turns into taking a week-long break
or a month ...
oh, I have a dreamhost question
I have a directory jmkasunich/compile_farm
is everything in that dir on the web?
if compile_farm itself is visible, then yes
which I believe it is
yeah, the index.shtml file in there is the main farm page
if you'd like some stuff elsewhere, let me know and I can set up another mapping (if it's not compile farm related)
there is lots of storage and bandwidth behind that, right?
500GB storage, ~6TB/month transfer
I was thinking of sticking some photos up there instead of serving them locally
high res ones are a meg or two, so I've been cropping and/or scaling a lot
can you serve up an HTTP redirect for image requests?
I dunno, never tried
or set up something like images.jmkasunich.dyndns.org
and point that at DH?
the redirect would work on a file-by-file basis, right?
I'm happy to have the files on DH, but I think it may be better to not have them on linuxcnc
toss the file into the local dir for convenience, then at a later time scp it to DH and replace with a redirect?
in case it gets moved or whatever
I also have willepadnos.net on there
I have been considering going to a paid account (its cheap) at dyndns
what's the cost?
that gives you a lot more capabilities, including multiple domains
for $8/month, you can register a domain and have it served at DH
the first domain is free
err - $10 if you go month to month, $8 if you prepay for 2 years
$24.95 per year
$15.00 per year for domain registration
ok, that's a bit less
but not too much
I really don't know much about domains
if you want to register a domain, you can do that with DH, GoDaddy, or wherever, and I can still have it hosted on my account
but if I read "Ability to configure various subdomains (sub1.domain.com, sub2.domain.com) and have them pointing to the same IP address or to different IP addresses" correctly, I could have foo.jmkasunich.org point at my (dynamic) IP, and bar.jmkasunich.org point somewhere else, like my ISP's webhosting or DH
well, it's different when you want to point at DH
you can't do it by IP
you can do it with a CNAME, though
bar.jmkasunich.org IN CNAME jmkasunich-bar.dyndns.org
well, I think we can use a CNAME to get from DH DNS servers elsewhere, but I'm not sure we can get to a DH host from external DNS that way
I wonder how that relates to "Included WebHop add-on provides HTTP redirection (redirecting www.yourdomain.com to http://www.yourisp.com/~yourusername/)
with optional cloaking:"
I don't recall the exact issues we had before, but I think we tried using external DNS to point at DH when the transfer was first done, and it didn't work
ok, WebHop would do it, I think
redirects tell the browser "that's not here, you need to go there instead"
and the browser asks DNS for the new host address
I can (and should) also investigate my own ISP's webhosting
at one time it was only 10Meg, but I think that has changed
I host the Van Norman site there
[02:20:32] <jmkasunich> http://www.dyndns.com/services/dns/custom/features.html
first I have to figure out what all of that means
yep - I'd check it out. like I said, you can host the images on my DH account, but you may not want them to go to linuxcnc.org, cncgear.com, thothsystems.com, coppercooling.com, coppercooler.com, or wilepadnos.net
willepadnos.net, that is
like the coyote
heh - typo my name once and I can never live it down ;)
dyndns may not be good. it looks like even the expert interface is geared toward sites that expect to be offline a bunch of the time
they offer an offline redirect, but you don't ever have to use it
oh - it's up to ~550 GB storage and 6.2TB/month
it keeps growing, and growing, and growing.....
that's ~2.5 MB/second, all month
so 100% saturation of full duplex ethernet
I was just going thru my pics again - I have one of the F86 on approach
he has the canopy open!
"yeah, nothing like riding in a convertible"
most of the canopy slides back about 3 feet, leaving a little windshield in front of him
some host at pacbell is hammering the linuxcnc site
well, somebody is anyway. 18 GB/day from linuxcnc.org
well, I guess that's ~25 ISO downloads a day, which is likely much more than we're getting
only need 12 more guys like that before you have problems
but not too far out of the realm of possibility, especially when combined with the wiki and other stuff
18G one day, or day after day?
estimated at 560G for the month
if its ongoing, its probably some crawler or something
I'm amazed at how much my puny home site gets crawled
3-4 search engines hit me every day
hmmm. I wonder how often cradeks backups run
the entire site (including wiki and ISO) is ~3.8GB
do you have the ability to do a robots.txt?
crawlers should check timestamps and only grab new items
[02:48:33] <jmkasunich> http://linuxcnc.org/compile_farm/jmk_images/IMGP0627.JPG
* jmkasunich likes his new camera and lens ;-)
I don't seem to be able to enable site stats for linuxcnc.org though. it's not working
that is nice :)
can't quite read the name on the side of the cockpit
I need to get the tools to work with raw files
GIMP doesn't like them (even with a plugin thats supposed to work) because they are 12 or 16 bit, and GIMP does 8 bit only)
I know the camera does some bluring when converting to jpeg
does dcraw work for that camera?
I think thats one of the things I tried
I should have been taking notes
so far nothing I've tried as actually worked - in some cases the raw-reader barfed, in other cases it worked but gimp barfed
I think there may even be an Ubuntu package for it
is that Linux?
[02:55:37] <SWPadnos> http://www.cinepaint.org/
you have the K10D?
ok. DCRaw should support it. try using it standalone instead of the gimp plugin
yeah, I definitely tried dcraw - I remember the website
ok - standalone or plugin?
I think I might have tried the ubuntu package, and that wasn't a new enough version, or some such
I've used standalone (though not with 16 bit color), and it worked quite well
I really need to take notes when I mess around with stuff like that
I know I had fits with some of the things I tried
yep. been there, done that ;)
follow the install instructions to the letter but stuff is missing or doesn't work, etc
if I had notes I would know _which_ one gave me fits
things change - notes get inaccurate over time (hopefully)
better to waste lots of time tryingthe same things over and over again
plus, you get a feeling of accomplishment when the program gets fixed, and you think you did something different that finally made it work on your system
I think that may be how many "normal users" feel when they install Linux and can actually surf the web and get email
I think synaptic has spoiled me
that and apt
it's so hard to compile programs these days, huh
thanks to someone on the emc mailing list i now keep a "captains log" of what worked, for future reference
crap. a fan in my computer just decided to get really loud
basically a shell script with lots of comments
can it go on the wiki?
um, its mostly stuff that wouldn't be very interesting to your average emc user
well, the wiki is the place if you think some of it could be useful to one or more users, not necessarily all or most of them
[03:18:59] <fenn> http://fenn.dyndns.org/pub/captainslog/captainslog
oh I see - not emc-related at all ;)
you know - it really is true that a vacuum is a better tool for dust removal than a compressed air can
oh? what if it's ionized air
the dust would probably still get blown all over the room
with extra ions hanging on it
depends on what you are trying to remove dust from
i've never used canned air, but shop air works great
you can point a puff of air at something from a distance
for vacuum, you have to get closer, and if the something is delicate, you risk sucking it up
vacuum is better for picking up swarf
compressed air is still the tool of choice for operating computers
as evidenced by the fact that I just blew out this one, and it didn't crash
(because I've been messing with photos just now, I was thinking of dust on lenses, etc
but I think I would have preferred that the dust and other junk go into the trash or something rather than into my nose and eyes
didn't crash doesnt mean no memory corruption
even better - install filters onto your cases so they dont get all dusty in the first place
computer cases these days are more hole than metal
that doesn't work. it only postpones the inevitable
it's probably been a year since I've had this case apart
it has screws in it and everything
SWPadnos: where (physically) is DreamHost?
San Jose or nearby
ok, that splains it
timestamps were off by three hours
and intially I brainfarted and thought they were 3 hours east
my upload bandwidth sucks
3 hours east should be in the middle of the atlantic
14K per second
right, hence my confusion
only two more
picked the 10 or so best shots, of the 240+ that I took today)
I think there's a problem with getting stats on linuxcnc, because of the .htaccess file joomla needs
dir listings are handy http://linuxcnc.org/compile_farm/jmk_images/
someday I'll figure out how to map a nicer (non-linuxcnc) URL to that dir
apache has a pretty powerful plugin called mod_rewrite
I can point at it rom any of the sites I have there
for now, I don't think linuxcnc is any worse than any of the others
once I have a domain, then I'll worry about it
ok by me
unless you'd like to see it not linuxcnc
well, I don't want to give the impression that it's OK to use the site for random non-EMC things
I'm not worried about it for now, but I think it shouldn't fall off the to-do list :)
maybe I should mv it from jmkasunich/compile_farm/jmk_images to jmkasunich/images, and then you can point some URL at it?
once I do the mv it will dissappear from the web until you do your magic
should I do it now?
or do you have better things to do than messing with DH stuff at the moment
duh, I can mv it and symlink to it from the exlsting place
then del the symlink later
the main question is where you want the link from
the sites I have hosted at DH are linuxcnc, cncgear.com, willepadnos.net, and thothsystems.com
the most generic of the available choices
it doesn't matter to me
I'll be linking to it from my blog or whatever, and I can use any of those
ok. willepadnos.net contains only photos from me and several friends at the moment :)
I can make it willepadnos.net/jmkasunich (no ~)
mv is done
ok. should take effect within 10 minutes
I notice there is no dir at the top level
one of those "if you don't know it's there, you shouldn't be looking for it" things
I didn't want directory listings there, so I put in a placeholder
seems to be working
worked for me, when I clicked from the "remap sub-dir" control panel page ;)
[04:03:27] <jmkasunich> http://willepadnos.net/jmkasunich
gets a 404 from here
hmmm. could be
those links aren't working from in here
all three of those are 404
yep, for me too
if they still don't work when the sun comes up, then I'll worry about it
how's the board layout coming along?
err - slowly :)
says /me who's been distracting you
I've got this weekend to get it done, and no distractions from the wife - she's gone camping with a friend
I do have a meeting with the customer on Tuesday morning though, so I really want to get it done before then
can you take a look at the layout when I've got it finished?
ok. should be sometime Monday, maybe tomorrow if I get really motivated
we both have Tuesday deadlines
mine - clean the basement to let the plumbers work
ah. that's a tough one
I have a baseball game tomorrow afternoon, other than that I'll be around
ok. I'll ping you before I send it
yay!. jmkasunich - I got the image dir working. I had accidentally set it up under cncgear. Also, stats are available for Linuxcnc.org. you need to log in with the emc board username/password to see them

ah, easy to fix
getting ready to hook the pluto up? or going to run it this way for a while?
don't really need it for half-stepping .. particularly with doublestep
my BASE_PERIOD is about 100us, really huge
I saw that - puts a smile on my face :)
my machining project for the day is a NMTB30 to QC30 modification
or to say it in a simpler way, I bolted a bench grinder to the mill table :-)
"precision varies by operator"
it's slow going, but it'll work
I can't find QC-to-JT arbor, so I'm modifying a NMTB-to-JT
at least I hope it's only the outside diameter of the flange that's the problem
once you get the taper correct - I would blue it and fit the chuck to see how close it is..
the tapers are the same
err I hope they are
I'm just reducing the flange
I could take a picture - it's an interesting setup I guess
right now I'm waiting for the grinder to cool
it's not continuous duty I guess
don't want to melt it
I cringe grinding on a mill/lath but we have done it to.
[19:59:56] <SWPadnos> http://www.practicalmachinist.com/ubb/ultimatebb.php/topic/12/1353.html
"NMTB 30 and Erikson QC 30 are not quite the same. The taper is the same and the NMTB 30 can be used in a QC 30 head if you remove the retaining nut and use a draw bar. "
yeah if there were a hole through the spindle, that would be a nice option
at least it more or less confirms that the taper is the same
the very slightly thinner flange may or may not make it not tighten
* skunkworks_ hates grinding operations - they take so long.
I think it's fun - I can shape things that are impossible to cut
it worked perfectly
great - good job
cradek: so you have a drill chuck now?
jmkasunich: when you get a chance watch some videos http://www.youtube.com/user/samcoinc
hmmm. interesting thing about doublefreq - the faster the motors go, the more the load on the CPU
not just the faster, the more periods that any motor needs a step, the higher the CPU usage (to a limit)
I can imagine a computer with UI response that varies with the beat frequency between the motors :)
SWPadnos: are you sure? I thought it always waited and did the reset, regardless of the state of the pins
oh - you're probably right
"write desired value, do other stuff, busywait if needed, write zeros"
no, I'm not sure
skunkworks: I saw most of those already
just saw the PCB one when I was reading back
jmkasunich: good - I didn't know how out of the loop you where :)
[22:30:19] <cradek> http://timeguy.com/cradek/01188770083
jmkasunich: yes as long as the drill is 3/16+
I might have to get a smaller one too
skunkworks: I blued it and the tapers do definitely match
a hint for the next time - put a paper towel damp with oil (or even water) on the table
that way the grinding dust will stick to it and not fly all over
grinding dust and ways do not get along
the ways are nicely covered, I'll be sure to vacuum the covers
what kind of chuck did you wind up with?
[22:34:11] <cradek> http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=140148547717
credek: looks great
dirt cheap, but seems very nice
so how much did you actually have to grind off?
I think it was a little over .1 dia
(the blog posting would be more usefull to others if you include the nominal NMTB diameter, and your final diameter)
I see you had the quill way down
make sure you wipe that off too, it will have grinding dust on it
hi alex! what country are you in today?
cradek: did you see the pcb video?
[22:40:06] <skunkworks> http://www.youtube.com/watch?v=Og6V-nS2dig
not the greatest but it gets the point across
the rapids are very fast
it flies from one trace to the next
heh - 450ipm if it gets up that fast
you need a 50krpm air spindle
did you decide to keep it yet?
there's still time ;)
something tells me if you decide to sell it you could hold an auction right here
too late to sell it to jepler...
how heavy is it?
it actually looks fast enough to be useful for PCB prototyping
no doubt about that
with a decent - non proprietary spindle that take 1/8 cutters - yes
might also want to gear the z axis 1:1 instead of 1:2
swap the gears - make it 2:1 :)
heh - might take some creative carving of the casting.
jmkasunich: I don't know the exact wieght - but it requires 2 people
not a UPS package then
the pdf says 300lbs
[22:54:54] <skunkworks> http://www.e-engraving.com/machines/new_hermes/img/New_Hermes_Vanguard_7200_Spec.jpg
still can't find the software to run the original controller
"Nominal Engraving Speed: 2" / sec"
32W x 25D and 300 lbs... desktop sized, as long as you have a reasonably strong desk
does it look like it could be disassembled into lighter pieces?
or is it a 250 lb base with only light removable parts
here are some pictures - I don't know how light you could make it,
[23:01:59] <skunkworks> http://www.electronicsam.com/images/engraver/
yah - it doesn't even break a sweat at 120ipm. remember this is made around 92'
do those dongles work with emc too/
wasn't someone wanting the activation key for emc a while back?
