OK.. Let's see if we can duplicate J.E.'s little prob.
[Global Notice] Hi all. This weekend would be a very good time to test Hyperion 1.0RC5.... please stop by irc.freenode.net port 9001 or #freenode-testing for more information .... thanks!
have I been missed greatly?
yes, yes you have
I sent flowers and everything
nobody here but us chickens
and all these canooks!
how ya doin LawrenceG ?
just about bedtime here... was a hot one here today
ditto, had patton fan goin on till a minutes ago (the gf said she was cold. - eeeesh, woman)
ordered some samples from onsemi.com.... bunch of fets and transistors to try and do a cheapo constant current drive that I can pwm from the mesa card
LawrenceG... yeah. what's a mesa card?
mesa 5i20 fpga card.... there is now a emc2 interface in cvs
let me look up the link...
why not just a micro controller, and a 2n3904, and a nice MosFET... like IRF510
you can even go bigger.. but hey... I don't know what yet though
[06:59:23] <LawrenceG> http://www.mesanet.com/motioncardinfo.html
look down for the 5i20
Computer TTL -> mircocontroller -> PWM (out) -> 2n3904 -> MosFet.
OMG... I love this KB... I love the play functionality that works with itunes.
parallel port is good enough for me.
mesa fpga has the advantage of pci interface, configurable encoder interfaces, pwm and lots of i/o for cheap
PWM can be done with a atmel chip easily... and they're really cheap.
$3-5 each. Cheaper if you buy bulk.
and tons of IO ports on them.
for servos, you still need to get the encoder channels into emc
LawrenceG... Gecko G100/G101 then.
they are for sale now I believe.
very similar idea, but all devel can be done on the pc without the rabbit problems
same price range
_all_ i want is something that can generate the pulses for me...
with the g100 you still have to buy 3 or 4 channels of gecko drive
part of the gecko functionality (the pwm) and encoder interface is already in the 5i20
just need the power bridge and the current limiting feature
I want an out of the box solution.
whats the fucking song.... somethign about a bird, slow, ALWAYS requested when a guitar is around, 60's, rock
60's rock? that's way too long ago and way before my time.
The 7I30 is a 3A, 36V 4 channel H-bridge motor driver for the 4I27, 4I34, 4I65, 5I20 and 7I60 motion controllers
I have one of these as well, but it only works for very small servos
it would be good for desktop machines
!!!!!!!!!!!!!!!!!! FREEBIRD !!!!!!!!!!!!!!!1
couldn't remember the sing title
well... good night all... time to dream of cnc and other such stuff
Jymmm, how's the machine?
still being worked on
I think I'll go make those pulleys I want to make ASAP. like even tonight.
EMC is all local to one machine, right ? i.e. there is no possibility to put io pins on another computer connected by tcpip
i find you developed something called HAL. i recently wrote something like HAL but it is networked and not realtime :)
erikyyy, yeah there is.
well... EMC has to be on one machine, but can be controlled via another.
ok and my version os extremly simple.
[don't ask me how, Ijust know it can be done]
i found that i have here in our company many io things. like the light switches on european installation bus, some selfmade io on some paralell port etc.
and i wanted to connect it all together with a clean interface
now i can write software and by editing the configuration file i can choose if some special io pin is on a computer with a parallel port in some room, or somewhere else with a DTR signal of a rs232 or or..
i must check this "classicladder" program
erikyyy, I think what you want to do, EMC _could_ do... but what you want could easily be written via a python, or C program.
just need a direct IO to it.
i am curerntly reading your HAL documentation
or a MAX232 chip to convert TTL to RS232.
your? nono... "the"
there should be a HAL-to-HAL by network module.
that I don't know.
by the way. what does HAL do on segmentation fault of the control software?
does it reset all io do a emergency state?
which is configurable on a per port basis?
erikyyy, best time to ask this kind of stuff, is when the developers have their weekly meeting. see topic
is this project a little bit germany based because i am in germany too??? :)
would be great ;)
originally developed by the NIS (USA)
see the wiki.
many things have changed since my first rtlinux experience i must admit ;) that was in 1997
LawrenceG: How difficult is it to program FPGA's?
Alpha1125: god bless your hostname ;)
Alpha1125 is now known as A-L-P-H-A
i probably should check to see if A-L-P-H-A is me. and hten if not, /ns ghost A-L-P-H-A <password> and then /nick A-L-P-H-A. but bah. Who am I hiding from? no one.
anonimasu: what happen ?
toady i want try to design an inlay skirting board..
should be quite simple to get inlay on wood
profiling some part
anonimasu: Can you try emc2 again ?
* paul_c did some more "fixes" and recompiled last night.
paul_c: in a little bit
paul_c: getting lots of unresolved symbols
wait a bit..
can you cut'n'paste a sample.
/home/an0n/emc2/rtlib/rtapi.o: /home/an0n/emc2/rtlib/rtapi.o: unresolved symbol rt_get_cpu_time_ns
/home/an0n/emc2/rtlib/rtapi.o: /home/an0n/emc2/rtlib/rtapi.o: unresolved symbol rt_shm_alloc

you're running make ?
could you do a "make clean && make"...
still the same
lemme login and take a look...
les_away is now known as les
03paul_c * 10emc2/src/Makefile.inc.in: damit.. commit on head.
anonimasu: That appears to have fixed it...
I need to leave
parents are dragging me along for fishing
as bait ?
copley drive on ebay for 29 bucks or so, not sure if its the kind you guys have used
and howdy ya'll
whats happening round here
nothing so far
I found a copley drive on ebay last night with a really good price, I didnt bid on it but thought I should mention it in here
something like 29 bucks
sounds like a steal... my $$$'s are all gone now.... i bought 2 new puppies.. ; )
[Global Notice] Hi all. This would be a really good time to hit the freenode testnet. We are finishing up testing on Hyperion 1.0 release candidates, and we hope to do a network-wide test Monday morning. I've just activated an ipv6 server.
[Global Notice] So if a *lot* of you could jump on the testnet (irc.freenode.net and all of the other servers, port 9001) it would *really* help.... *hint* *hint* ;) Thanks!
[Global Notice] For more information, please stop by #freenode-testing on the production network, or turn on wallops (/mode yournick +w) .... thanks!
[Global Notice] Again, if you're having trouble connecting, please stop by #freenode-testing and we'll sort it out. Thanks!
[Global Notice] Hi all.... IPv6 on the testnet is up and running, please test! goethe.freenode.net port 9001 .... if you have any problems, please stop by #freenode-testing here ..... thanks again!
hmm, with emc2 im getting a compile error thats aborting make
something in _sem.c
this doesnt make any sence
_sem.c:220: warning: control reaches end of non-void function
make: *** [/usr/src/emc2/src/.tmp/_sem.o] Error 1
hmmm... Paul recently made a commit to that code
its not compiling for me, not really sure what im looking at
I'm doing a cvs checkout, I'll check it out
_sem.c: In function `rcs_sem_wait':
_sem.c:196: parse error before `int'
there we go
sometimes I wonder if Paul actually tests his changes before he commits them... according to the compile farm, it is broken on at least 3 of four systems
found the prob
jmkasunich: he's trying to find the issue with the MUTEX locking problem
that I reported several months ago.
jmkasunich : what did you see?
or what line number in the file, so I can learn something
understood, but he committed code that doesn't compile - just a simple typo
there are decls at the start of the function, then a couple lines of actual code, then more decls
that's a no-no
I moved the second group of decls up and it works now
(at least _sem.c compiles)
03jmkasunich * 10emc2/src/libnml/os_intf/_sem.c: reordered declarations and code in rcs_sem_wait(), decls following executable code causes compile error
03jmkasunich * 10emc2/src/hal/utils/m5i20cfg.c: removed #define GNU_SOURCE, this is now done by the makefile, the duplicate causes a warning
03jmkasunich * 10emc2/src/libnml/posemath/_posemath.c: removed #define GNU_SOURCE, this is now done by the makefile, the duplicate causes a warning
gezr: CVS is updated, do a fresh checkout and try it
03jmkasunich * 10emc2/src/emc/kinematics/tp.c: fixed an unused variable warning - once the TP changes are known to be working, the stuff inside #ifdef OLD_CODE should be removed
okay, been trying to do that, I guess something hadn't refreshed, I get a line that looks like this
that means you have a modified copy of the file on your box
you've been editing it yourself, right?
Im trying to learn some
do you have a developers checkout, or anonymous checkout?
I did a fresh co after you initial update to _sem.c but same error existed
if you have an anon checkout, there is a lag of a few hours
it's also possible that your manual edits conflicted with my changes
delete _sem.c, then do "cvs up"
it will say something like "_sem.c was lost" and the load the latest version
although if you have an anon checkout, that will still not have my fixes
ive got it now
you moved 2 lines
im trying to understand the diff
in C, you must do all declarations before any executable code
retval and time were being declared after the executable code that inits sops.sem_num, etc
i may not be getting the proper code
ill have to remember how to check it back out, its been some time for me
to update your existing checkout, just do "cvs up -dP"
(you must be in the top directory of the checked out tree)
jmkasunich how the hell are ya!
I was using an anonymous co, ive switched to logged in now
I havent booted that box in over 5 months I think
We all have to be a lil crazy to survive in this world
jmkasunich : im getting un updated files
or the version before your commits that is
exactly what command did you use for the checkout? (copy it and paste it here)
cvs -z3 -d:pserver:firstname.lastname@example.org:/cvsroot/emc co emc2
previous line was my login
cvs -z3 -d:ext:email@example.com:/cvsroot/emc co emc2
the pserver tells it to use anon checkout, even tho you supplied your name
ext tells it to use external authorization, which is SSH
ah okay, when I made the changes to my file, I didnt put a space after the 3rd define
you mean a blank line? that shouldn't matter
yeah, I moved the same 2 lines to where you moved them
strange... but the new checkout works?
its on a 350mhz box
yeah... I'm waiting to see what the compile farm says... it is 200MHz :-(
im hopping to have some good news for the guys who do what I cannot in the near future
jmkasunich : passed the last known error spot
going to test the build
jmkasunich is now known as jmk_away
jmk_away : your modifications resulted in a complete build and operational program for me, I hope as well for others
LawrenceG: are you arround ?
the DAC board is still not ready
but maybe i will finish it this weekend
no problem... my projects are progressing very slowly this summer
same here :-)
waiting for some samples to show up from onsemi (Motorola)
its more or less ready, i want to put some relays and some digital inputs also on the board for Amp enable amp fault and so on
leds are GOOD as well... dual color for drive indication
oh oh oh, um that ebay auction for the copley, they have a lot of stuff for sale, even a very inexpensive allen breadley slc 500 plc and a programer
thought on that, maybe such a LED row known from the audio amps
even a dual color single led will show +- drive with intensity being the magnitude... I used it on an old hydraulic servo interface card I designed and they were great... most faults resulted in full on in one direction or the other
dont forget to put test points on the pcb for easy scoping of encoder and servo drive signals
great for glitch hunting
make sure they're located right next to critcal circuits that'll blow up instantly too! =)
i hate it when that happens.... scope probes blow up more things!
scope? I was talking 10KV voltage probe that looks like a turkey baster! =)
that sounds like some of the research projects les might undertake ;)
les made progress yesterday... get one 1W out of it
I wonder if he has tried the tp fix yet?
you get your USC card yet?
I havent hooked it up though I need to get connectors & box from work
and get my roll of single wire cabling..
what the hell.... you didn't get those things while you were waiting for it?!
* Jymmm hides his face in the shame of anonimasu
I got it yesterday then I went to party with some relatives to celebrate a birthday
you dont need sleep
today I was dragged along for fishing
you can sleep when your dead
Jymmm: if this keeps up I'll be dead soon ;)
just put the USC card in your will to me
nah, I am going to have a look at it tomorrow :)
it looks great
hey, can you take a hi-red photo of it?
I have a box laying around ;)
are you going to mill a pcb?
it's not too fancy..
not THAT hi-res.... jsut the pic on the website sucks.... too small to see any details
I dont have a good digital cam here..
if I go to work to pick up the box and stuff I will
the fancy stuff is probably in the XILINX fpga..
well use a bad one, just make the image large.... 1024 at least
I have a quickcam web
I am looking forward to trying the USC
I've got the USC now
how's it working?
I havent tried yet
got it yesterday went to a party to celebrate mother's & fathers birthday with some relatives
or maybe the day before..
cant remember but it looks nice
I am going to hook it up without the gecko interface at first..
I can live without encoder feedback, a little bit
Jymmm: you bastard, You made me so damn curious about trying it.
got a gecko interface for the USC
so I get real encoder feedback even with the power off..
what gecko interface?
the one jon elson sells
got a link?
[20:39:17] <anonimasu> http://www.pico-systems.com/images/geckouse1.pdf
[20:39:23] <anonimasu> http://www.pico-systems.com/gecko.html
nice.. seen it before
it seems a bit messy to hook up :/
dont you think so?
I did a lot of cabling lately.. so I wouldn't mind
me neither really
but I should get the box and stuff..
I have a sealed box for the cards..
*curious to see motion*
tomorrow will be hooking up time
atleast for the USC
the gecko interface will wait a bit..
making parts is more important for now :9
and getting a emc2 driver toghter
that would be smthg ;)
anonimasu : That's what I'm here for =)
writing a emc2 driver?
if I went and got the cabling and the box I might have the machine running in a hour..
03paul_c * 10emc2/src/libnml/os_intf/_sem.c: Remove SEM_UNDO - Leads to bad things under certain conditions..
am <anonimasu> Jymmm: you bastard, You made me so damn curious about trying it.
I just need a 9v poiwer supply..
it's just hooking up the step/dir outputs and the ground/common connectors..
03paul_c * 10emc2/src/libnml/inifile/ (Makefile inifile.cc inifile.hh): Implement tilde expansion. Another todo removed from the list.
paul_c: how's it going?
I like the idea of the opto and the SSR's ont eh USC
alex_joni_: making headway.
I like the watchdog..
I find runaway machines scary
paul_c: one question
anonimasu: That's what the FM button is for..
do you deliberately remove _inifile.c from the Makefile every time?
think this is the second or third time
yes you.. check the commit
I know libnml doesn't use it..
but it gets linked into another emc2 binary :D
maybe we should move it there..
the Inifile class contains all the functionality of _inifile.o, so it shouldn't be needed any more.
well.. you can't link/use the Inifile class with a plain .c file
or at elast not trivial
How much is dependant on _inifile.o ?
halgui is, not sure about other stuff
sorry.. am tired right now
hmm.. did anyone touch mathstubs lately? it seems to fail on all slots
[20:58:37] <alex_joni_> http://www.linuxcnc.org/compile_farm/
alex_joni_: The hal stuff is not my problem is it.
I agree partly. breaking HEAD might be
it's CVS damit. head may well get broken from time to time.
gimme a few mins to see what can be done to fix it.
I am in no hurry
just wanted to point it out..
last time I fixed it by bringing _inifile.o back
I did try to use the Inifile code from the .c source.. but that got nasty
(tried a struct wrapper over a class with indirect funciton calls, got out of hand)
alex_joni_ is now known as alex_joni
Jacky^_ is now known as Jacky^
Rescuers save at least 22 in air crash off Sicily
well.. there are still more than 6 billion left
03paul_c * 10emc2/src/ (8 files in 3 dirs): Remove the dependency on _inifile.o.
not pretty, but it should work in the short term.
* alex_joni checks it out
paul_c: you got an older BDI handy?
how old ?
something with mathstubs
seems it's not compiling.. might be the _GNU_thingy
I don't see anything else changed...
matstubs should be conditionally compiled & linked...
right.. that's why I asked for an older BDI.. 4.20 (the one I use) doesn't
but all others? seem to need it and fail during the compile
got 2.4.25 headers...
03paul_c * 10emc2/src/rtapi/mathstubs.c: Need to conditionally compile mathstubs.c - In the meantime, sidestep the prob.
what was wrong there?
I couldn't see anything wrong..
ISO C99 defines isnan
oh.. I see
assumption: egcs defines isnan with _USE_ISOC99....
03paul_c * 10emc2/src/rtapi/mathstubs.c: Force a build on the farm.
* anonimasu yawns
heh.. nice talk on the gecko list
jmk and rsz biting their behinds ;)
tht's a dead horse
I'll read the archives when I can be bothered.
[21:55:26] <alex_joni> http://finance.groups.yahoo.com/group/geckodrive/message/6137
jmk had a nice talk with Steve Hardy to make the G-Rex work with emc some day
and robin got upset, as he thought it might bloat the code inside the rabbit ;)
jmk_away: btw, I like the writeup you did --> http://home.att.net/~JMKasunich/EMC_Docs/EMC_Home.htm
Jymmm: that's a bit old, but accurate
alex_joni no matter, still explains things I only heard
pictures are nice
Now, if I could only find the java &/or windows GUI
tkemc runs on doze
I did run it
it's an EXE ?
and the java gui.. it's .. yucky
but there's tcl/tk for doze
X take ups too many resources
tcl is an interpreted language
use usrmot ;) (non-x)
or ssh -X
and run the X server remotely
on doze for example
ot client remotely?
client with X server
ssh to the box
and run emc
run keystick as your remote GUI.
and the GUI will pop up on the client box
I'm runnign keystick on the box already
exporting an X session via ssh is wastefull on resources.
no need for ssh (lan)
paul_c: still better than running X on the box
and it only takes up 20-30 kB
for tkemc that is
it's not memory as much as cpu cycles
I meant data transfered
Jymmm: then I suggest using emcserv
alex_joni which is what now?
and GUI on another box
a little program that allows some of the components of emc to be run on another pc's
get back to jmk's drawings
not based upon X ?
all the components that connect through NML can be on different PC's
this has nothing to do with X
emcserv isthe networking widget for NML message passing via tcp/ip
you can run a GUI on doze for example
so I can have dual consoles going for control and monitoring?
or even distribute GUI, IO, and motion on totally separate computers.
but the local one can miss aswell
alex_joni say that again?
so only one is enough
well, I was thinking just in case the remote link fails or locks up
Hmmm, I wonder if I can run keystick in putty
then you mighthave a problem
sure you can
I dont' know of any good x servers for M$ (gpl)
btw.. I run putty with X-forwarding
Cygwin-X on the doze box, and emc runs ok
isn't cygin a clusterfuck to install?
cygwin-x is free
not hard to set up
comparable with emc ;D
oh two hours to install huh
smthg like that. abotu 100-150 MB to download
sorry, but is there a way to run emc under a 2.6 kernel ?
rcsu: you'll have to run emc-bdi4 or emc2 on 2.6
what about vnc?
* paul_c is running emc on 184.108.40.206
* alex_joni is too
doing a run of Les' turkey calls.....
Jymmm: care for a DCC?
His ol' wrinkley is going to be out of a job I fear....
alex_joni dcc isn't, no.
darn.. I'll post it on my http
If I could get eht wifi working on my laptop with debian, I'd be happy
knoppix LOVE my laptop, except for the wifi
Don't use broadcom chipsets
it's not, it's an atheros
could be PEBKAC too
[22:15:08] <paul_c> http://www.linux-wlan.org/docs/wlan_adapters.html.gz
alex_joni what is this?
tkemc on doze
with ini and nml file
connects to emc
tcl8.2 and tk8.2 needed
alex_joni: You sick puppy. ;-p
think ray set this up.. or somebody else
it's pretty ancient ;)
but it works even with emc2
Jymmm: but I build another goodie ;)
jmk_away is now known as jmkasunich
an emc running on doze with emcserver
and you could connect on GUI running on linux to it
no idea who would want that.. but anyways
jmkasunich: hello there
alex_joni Well, if I go mobile, having gui on laptop would be nice then would only need power/cat5 loopback cable
seen the talks on the geckolist ;)
I see you guys are investigating the mathstub problem
paul_c commited some fixes for it
is the compile_farm still compiling?
yeah - I just kicked off the farm
jmkasunich : btw, I like the writeup you did --> http://home.att.net/~JMKasunich/EMC_Docs/EMC_Home.htm
it's old now
jmkasunich but explains a lot of things I only heard
we all are ;)
alex_joni speak for yourself, I refuse to grow up
I've always understood things better with block diagrams and other visuals rather than text
jmkasunich Well, it was more the "modules" of emc 'emcmot' as example.... I had nfc lcue
alex_joni : what do I need to download and install? (urls please)
hmm, seems like there is still a problem
this TclTkMouse is out of my realm
Jymmm: thought you'll figure it out
[22:26:36] <Jymmm> http://sourceforge.net/project/showfiles.php?group_id=10894
03cradek * 10emc2/src/libnml/inifile/inifile.cc: (log message trimmed)
Fix bugs in Inifile::tilde - reliance on being passed an empty but
null-terminated output buffer, crash if $HOME isn't set, returning
wrong results when unsupported tilde expansion type was requested
(~user/, etc), unhelpful error message that didn't tell you where
the problem was or what to do about it, wrong documentation in
dang.. ran out of power on the laptop ;)
[22:41:37] <alex_joni> http://prdownloads.sourceforge.net/tcl/tcl823.exe
that's all I'll need?
what is this msys_mingw stuff?
msys/mingw is a build environment for win32 hosted on unix
Jymmm: got the link?
[22:44:56] <alex_joni_> http://prdownloads.sourceforge.net/tcl/tcl823.exe
hmmm... building OK on live now, but still fails on BDI2.20 and TNG
yes,ty. is that all I need?
anyone know a design for a small/cheap dc servo drive? preferably chopped?
ISTR les had a plan for one ?
jmkasunich: ok, different problem now
G320 isn't cheap/small enough
alex: yeah, another semaphore related problem
dont need/want the encoder/pid etc
robin_sz: you can chop it off ;)
just want a raw H-bridge?
robin_sz: I have some schematics if you want
or bridge + current loop?
only H-bridge + current limiting
I guess bridge and a current feedback loop
* robin_sz nods
[22:47:42] <alex_joni_> http://dsplabs.utt.ro/~juve/yanor/
how many volts and amps?
3 to 4A will be enough, 30v I guess
should work ok
my motors were about 10-15 Amps
alex: yanor was your project?
alex_joni that's a kiddie porn site!
wasted some time on it ;)
I would chose a _very_ different approach now
Jymmm: heh... see, if you want doze.. even tcl needs to reboot it
ok, I see a pic of the bot and two people... which is you? ;-)
the one bad-ass looking is alex
the one with the green hair
the one with the black t-shirt
nah, the one with the black.. whatever
ahh.. a face to go with the name
lol.. thought you've seen pics of me
maybe, not sure
robin_sz: the h-bridge schematic is for 2 H-bridges
was designed to run 2 DC motors, or a big stepper ;)
there's even a pic in there to do step/dir conversion for the stepper
using P channel FETs for the high side - that's cheating ;-)
I started with all-N-types
and using IR2111 iirc.. but that didn't work
blew up a bunch of them, then I scrapped that approach.. ran out of time ;)
any idea what went wrong?
dunno.. I think the IR2111 weren't working properly
alex_joni_: how many years old ?
* jmkasunich just acquired a couple tubes of TO-220 N-chan FETs, 60V 40mOhm
alex_joni_: are you a student ?
what?I finished 2 years ago ;)
jmkasunich: are you sure you have the latest CVS on the farm?
beliece I do, it does a cvs up every time
inivar is failing
there was a problem with the time on the farm, a couple slots keep getting screwed up
we keep having power failures here from thunderstorms - a several in the last few weeks
we had those too
every reboot a couple slots are an hour off the others
seems weather is slowly getting bad
this morning I reset two slots, but I screwed up and made them a day off (8/7 instead of 8/6)
Jacky^: which photos?
fixed that now, but maybe bad timestamps are screwing things up
alex_joni_: yours, i suppose..
I have LOTS
i've seen some album
[23:01:19] <alex_joni_> http://dsplabs.utt.ro/~juve/photos.php
about 12-13000 more on my laptop
digital camera ?
nice, good definition
btw, what graduation is that? PhD, Masters?
Jacky^: just checked 14757 ;)
seems like a big project for BS
well.. I wanted to do it ;)
I believe over here that would be accepted for Masters work
over here too
and if you threw enough theoretocal crap into it (lots of formulas) you might get PhD too ;-)
I got too tired for Masters ;)
did half of it.. then I gave it up, better things to do
yeah... let's see, I can keep paying the school for a masters, or I can get a job and somebody will pay me... what to do, what to do?
well.. at least here we don't pay for school :D
you get to pay for a second college
but the first one's for free :D
given that you get in of course
with a decend grade.. if it's too low, you still get to pay
but it's a bit less than over there (I heard)
about 4-500 $ / year
yeah, just a bit lesss
but it's still in credits
prices here range from a couple thousand to 20K or more
so they should be compatible
seems _sem.c from /libnml/os_intf/ doesn't get compiled right
_sem.c: In function `rcs_sem_wait':
_sem.c:210: warning: implicit declaration of function `semtimedop'
I'm gonna delete those subtrees and do it again, just in case something got screwed up
make: *** Warning: File `_sem.c' has modification time in the future (1123446270 > 1123360429)
Jymmm: looong reboot
alex_joni_ : fixed some tuna
jmkasunich: even slot 4 complains of clock skew
yeah, I reset clocks on 2 and 4
but 3 too
jmkasunich: run ntp..
PITA to set up
it'd save you messing with clock skews :)
alex_joni_ is now known as alex_joni
I don't even know where to start...
if I could get it working on this box, then maybe I'd try it on the farm
apt-get install ntp-XXXX
and place ntpdate <someserver> in your crontab..
[23:16:11] <anonimasu> http://www.eecis.udel.edu/~ntp/ntpfaq/NTP-a-faq.htm
or well grab the package ntp and just set up ntpdate to run from cron
and ignore the FAQ ;)
[23:18:49] <anonimasu> http://www.eecis.udel.edu/~ntp/ntpfaq/NTP-a-faq.htm
might be overkill :D
ntpdat and ntpd is pretty much fit--and-forget
the fitting part is the problem... I have five boxes (counting this one) and four different distros
apt-get only works on one of them
grab the .tgz and compile it
alex_joni_ is now known as alex_joni
ntp is good stuff =)
I prefer WWV, but what ya gonna do =)
damn... all the clocks now are GPS (satellite) based =(
Jymmm: smoked a cigar ?
Jacky^ : No, once in a while a pipe on rare occations
Jacky^: sounds more like a joint
nah.. Jymmm don't smoke joint
not in years
so how do I find a ntp server?
time.gov has a list
jmkasunich might as well use nist's =)
is all you need to know
Jymmm: the strange thing i remember , when i have been in California, for the roads lots of people asked cigarettes, seeing to me to smoke..
in 500 mt 4 peoples :\
ok, that worked here... now to do it on the farm
jmkasunich you might want to add the IP addresses, sometimes I've seen GOV dns be offline
but later - my wife wants to go out
I will use straight IP, simpler
jmkasunich is now known as jmk_away
anyway .. how is the tp today?
I wish Keathkit was around today... would be some neat products
I had a heathkit SW radio ...
deaf as a post
I want one of these --> http://www.schaffrath.net/mac.html
is wwv still on?
guess its outdated now
not at all
according to WWV it's too late
* alex_joni goes to bed
just run ntpd, much better :)
get well under 10ms easy
and for REAL accuracy, theres GPS
happy welding dreams
where do you think gps gets it's snyc from?
Jymmm: from the stars ;)
actually GPS is running a few atomic clocks, synched
Jymmm: would it be from the network of 12 caesium beam clocks that run it?
[23:57:40] <robin_sz> http://tycho.usno.navy.mil/time.html
you can get GPS clocks that will be remote synched to within a few tens of ns of the master .. GPS is stunningly accurate
put it this way ... on of the last jobs I did at the BBC was to rip out the rubidium vapor reference and replace it with GPS clock
