Also calibrating a freq counter on the work bench.... nothing like waiting for a crystal oven to warm up and stabilize..
LawrenceG thats what WWV is for =)
maybe he's calibrating the oven crystal against WWV
heh, maybe =)
I built a gps locked 10mhz standard.... its like 1000 times more accurate than zero beating with WWV... very cool. I need to make a 10mhz distributions system for the bench so that I can use the 1 reference for all my test gear. Nothing like 10 10mhz oscilators all on a different freq.
you know how unstable those crystals are =)
LawrenceG what? since when is gps more accurate than wwv?
especially since wwv is used to adj ooffeset gps
If I lived next door to WWV it would be better, but the propagation of the radio signal really messes up the accuracy of wwv because of the doppler shifts.
LawrenceG where oyu at?
off the west coast of Canada... Nanoose Bay... 49.31N, 124.23W
[00:08:32] <Jymmm> http://www.boulder.nist.gov/timefreq/service/gpscal.htm
-what is WWV?
LawrenceG: what about WWVH Hawaii?
gezr: the atomic clock
gezr: the atomic clock callsign
LawrenceG: You are not marked on the map.
Ok... not that far off the west coast...
LawrenceG and a simple yagi
I was on the emc map at one point... The dot probably sits on top of Vancouver BC.... its about 100km away.
(60 miles to swim)

That would be me...
I wish I could make it to code fest.... that would be a real hoot....
not sure if the politics of indenting style could be digested thou...
Initial results are poor on indent runs...
indent is barfing out over a couple of rs274ngc files.
hrrmmm... Quite a cluster of dots along the northwest coast
Its hard enough to get every programmer in one company using the same style (manager needs big hammer). Hard to do that on world wide projects.
you implement an indent run on CVS checkin
each programmer checks-out and then indents the code to his or her desired style to work on
that way the CVS is in a standard format and programmers can have it in their desired format
could work... It would be close enough to each persons style that they could scan it easily.
with the approriate indent options on checkout, it should be exactly the format the proggie requires
any programmer who has a style that is not creatable by appropriate indent settings needs "re-educating" ;)
pick me.... i r just an engineer
indent -kr or indent -gnu are good places to sart
if you find your indent settings extend to several hundred weird options, thats a bad sign.
yes... played with indent and it certainly does have "options"
paul_c: On the next bdi disk... how about a script that does all the apt-gets for the devel stuff? This could be run manually for those wanting sources. Cut and paste off the wiki site works pretty well as the alternative.
LawrenceG: all it needs is a file with:
dpkg --set-selections < filename.txt
apt-get dist upgrade
si it just needs a file of all the various dev packages needed with "install" next to them
LawrenceG: All the dev packages are on the CD
thats not quite the same thing
install is going smoother this try.... I also doubled the swap partition to 512mb on this install...
they still need to know what they need to install, no?
IF they don't know that gcc needs to be installed, then perhaps they should be doing something else.
oh, well, its just gcc, then fair enough
I thought it might have been a load of other -dev stuff
AND if they can't be bothered to read the notes....
then there is always synaptic if anyone is scared of the command line.
LawrenceG: if, after installing, you would care to do a dpkg --get-selections > base_version.txt and then after adding the dev stuff do it again to dev_version.txt and diff the files, it should reveal exactly the differences.
synaptic does help in finding things.... needs a batch mode though.... somewahy to export a list of installed packages that can be used again to re-install all the same pakages on another box.
thats EXACTLY what --get/set-selections does
ok... must have missed something
you can run either the ENTIRE file into it
or ... just the added bits for making it a dev system
this is the Debian way of doing things
or make a emc-dev pseudo package that installs the dev stuff in one hit
Damn... bdi install just dumped again.... it makes it all the way to post install config and then black screens into an X error and tells me its safe to reboot my system
why not just install debian Sarge and add the emc stuff later?
might try ubuntu... have that running on several other boxes and its debian based.
LawrenceG: have you tried burning at a lower speed than your drive is rated for?
"Are you happy to see me or is that an atomic clock in your pocket!" http://www.boulder.nist.gov/timefreq/ofm/smallclock/index.htm
yes, have burned 3 differnt versions of 4.20... they verify ok now that I'm not using my dvd burner to make them.
Ah - OK> (I had a problem with one disc burned at full speed - fixed at lower speed)
* robin_sz had to repair an atomic clock once
well, a rubidium vapour frequancy standard anyway
robin_sz: Hey! Just found a photo of you doing that! http://www.boulder.nist.gov/timefreq/general/museum/nbs-1.jpg
"Love your hair!"
it was a fun thing to mend, and quite entertainng to re-align
I've only played with cesium vapor
we never had one of those on station,
just two rubi's
we'd lock agaisnt the reference in London in a morning, typically it would only drift by 1 cycle of 4.43mhz during the day
the cesium was used in a transmitter of sorts
and thats all I can say on that =)
chessie4 is now known as chessie
Anybody on that can email me a copy of /etc/sources.list from a bdi install (prefer 4.20)
you mean /etc/apt/sources.list i guess, and i dont have that version, nor the specific stuff to emc
yes, sorry... trying to do a bdi install and it wont work here... I got the ubuntu distro to install, so if I have the sources.list, I should be able to apt-get all the needed emc stuff.
I have no idea, wish i did
no worries.. paul_c is "The man" for the bdi stuff.... he was on earlier
# The main repository for Debian packages.
# Synergy updates.
# At some point, a repository will have to be created
# for BDI related packages. Meanwhile, a dummy line..
## deb http://emc.repository/debian
That's all I have on a BDI 4.18
Paul had mentioned an EMC repository, but I can't remember the exact URL
I dont know it
Try the Wiki: http://www.redpoint.org.uk/cgi-bin/emcinfo.pl?DebianInstall
ok... paul did say most of the packages were on the bdi cd.... I'll try a cdrom-add and play a little.... getting the real time kernel would be the big leap forward.
This seems to have been updated within the last day.
bindo looks perfect...
Anyone know how to get a CD-rom working?
(funny - I just watched Finding Nemo last night - there was a little problem with names :) )
cnc_wright : hu?
as in apt-cdrom?
I don't appear to have /dev/cdrom
apt-cdrom returns:E: Unable to stat the mount point /cdrom/ - stat (2 No such file or directory)
/dev/cdrom is often a link to one of /dev/hdb, /dev/hdc, /dev/hdd
check dmesg to see what it routed it to
it could be being treated as a scsi device, /dev/sda1 would be an example, but the symlink should be there
dmesg would show dmesg | more or | grep cdrom
cat /var/log/dmesg | grep cdrom = 'nothing'
then the issue lies deeper, did you recently compile a kernel?
how about mount /cdrom ?
you may have left out cdrom support
During boot modprobe seems to cause a stack dump but the boot keeps going
I am working off of a 4.18 BDI
I have an onboard AIC 7890 (7980)?? scsi controller
I had a scsi cd rom
I took that out an put in an ide cd-rom
after the initial install was made?
it could be a modules issue
I can't seem to get the scsi controller turned off all the way in the bios and my mobo doesn't have a disable jumper for it
I cant be for sure, I dont spend my time on a linux box like I used to
the scsi part should also be supported
why its not I dont know
yes. It worked great during the install...
try this, modprobe scsi-ide
or modeprobe cdrom
modprobe that is
the proper moduels may not be loading or a similiar issue
bios shouldn't matter should it? won't linux disregard it completely?
they return: FATAL: Module scsi_ide not found.
FATAL: Module cdrom not found.
cdrom may not be a module, but part of kernel
although i know squat about the BDI
Maybe I can download the kernel source and try a new compile
cnc_wright : you may have to rebuild a kernel specific to your hardware,
I think you should have pre patched stuff with that install, I dont know
i find that once you are comfortable doing just that, it is so nice to tune the system
are you using BDI?
I think the kernel source is still on the cd-rom and I cant get to it :(
if you compile from kernel source, you will need to downlad the RTAI or RTLinux source and patch the kernel prior to copmiling
what do you have in /etc/fstab? (for /cdrom )
assuming you d/l the latest source
cnc_wright : check the dmesg again and pay close attention to what It had to say, it may be a simple fix
just check all of it over
see how the last boot progressed
fstab had no cdrom entry
useful, but not a requirement to access it
BDI installed kernel-headers-2.6.9-adeos & kernel-source-2.6.9-adeos.tar.bz2
you say you installed the ide cdrom after the fact?
ide cdrom came after install yes.
how is it connected to the mobo?
are all the cables on teh cdrom good to go/
Is the kernel source I mention above prepatched for RTAI?
yeah I believe so
2nd IDE bus as master
did the bios at boot detect it?
is there anything else on the 2nd?
just untar the kernel-source... file (in /usr/src, where it was placed)
make sure the bios detected it at boot, you may need to just reboot and watch closely
you can then link linux to kernel-source-2.6.9-adeos, to make things a little easier
yes. I had left the BDI cd in it and it booted off it.
you could retry the install
give it a chance to find what it is you have now
sometimes linux gets a little flakey if you have an ide device on a controller as the only device selected to single as opposed to 'single'
thats sorta a cheap but effective way to go around it
At some point I have to learn myself how to fix this beast without full nuke. I have installed about 8 time so far...
most bios can work around thus
but once linux starts loading, it disregards the bios as i understand it
cnc_wright: just untar the kernel-source-2.6.9-adeos file, then copy the file /boot/config-2.6.9-adeos to .config in the source directory (that was just created by tar)
Should I try putting the cd on the primary bus as a slave
that would be a very good place to start
don't move anything - it booted and installed just fine, right (or was that the SCSI CD-ROM?)
especially since you already know the controller is accessign that bus since you can boot it
Cool. I have two things to try here. Swap the cd to the other bus and build a new kernel.
cd swap takes less time ;)
I wan't a new kernel anyway so I can specfically leave out the scsi modules. That might fix some of my probs.
my ancient celeron would spend all night on a recompile
what does 'dmesg | grep -i cd-rom' tell you?
I installed of the scsi cd-rom
did the scsi drive just fail or something?
you know, modules are great for flexibilty, but i love a monolithic kernel
SWPadnos : Uniform CD-ROM driver Revision: 3.20
OK - that's waht I get as well.
what does 'lsmod' tell you is loaded?
scsi drives didn't fail but I am getting a stack dump about the scsi driver during boot
scsi_mod 105764 1 aic7xxx
so thats the scsi controller module
and it is being used by the hardware
is the scsi cd still attached?
how about 'dmesg | grep ROM'
no. but modprobe finds it during boot and I get a stack dump
hdc: R/RW 8x4x32, ATAPI CD/DVD-ROM drive
hdc: ATAPI 32X CD-ROM CD-R/RW drive, 2048kB Cache
even if you could disable it in the bios, linux would still find it on boot
thats a good sign isn't it?
OK - now tell me what /etc/fstab says about /derom
cdrom, I mean
and yes, it is a good sign
how have you tried mounting it?
sorry to rehas old questions i'm sure you already answered
/etc/fstab has nothing matching "cdrom"
cnc_wright here's a nickel kid go out and get yourself a real computer
there should be an entry (after a line saying "Automatically added by firstboot.sh") /dev/sdb /cdrom ...
/dev/fd0 /floppy msdos,vfat noauto,users 0 0
is the only entry after that
it should be before that (I have two sections with that description) add this line:
/dev/hdc /cdrom iso9660 ro,users,noauto,unhide 0 0
line is now added.
Do I have to reboot?
now mount /cdrom (with a disc in the drive)
when i mount my cd, i usually 'mount /dev/cdrom /cdrom'
and tell it exactly what to mount
that's what the /etc/fstab line is for
siado how naughty making directories in the top level!
you racy thing you!
mount: mount point /cdrom does not exist
well, i don't actually, i was just following the example
I bet you jaywalk sometimes too!
in my slack it's actually /mnt/cdrom
the BDI default is /cdrom
only on sundays! :P
well - it IS Sunday here! :)
* cnc_wright I have a CD-ROM!!!!
thank you, thank you :)
Way cool beans. Thanks ALL!
really it's not hard
so we were both right :P
make some aliases
just yours is longer lasting
alias cdm='mount -t iso9660 /dev/cdrom /media/cdrom'
alias umcd='umount /dev/cdrom;eject'
that fire's out
how the heck do you get a usb wireless adapter working?
siado put those lines into ~/.bashrc
eh, i will eventually
i'm still being lazy about it
i don't know if i want to keep slack or not
I ran slack for like 6 years
just got too hard to keep up with
i have forever
until i got osx
I hate apple
that's kind of what I'm thinking now
i love my mac for what i use it for
I hate apple on principal
because they're scumbags
i open email attachements fearlessly
even if i don't know the sender :O
them and their closed hardware
how old were you when they opened, then closed their hardware?
and screwed all them poor slobs who started clone companies
that would have been a brilliant move say 15 years earlier
man if they actually mattered they should have gotten sued over that whole deal
ibm ensured dominance in that respect
but i'm no fan of MS either
no appled has sealed their own fate time and time again
they fir my niche though
they're effete elitists
They make good door stops
i am thinking i'm going to just string a damn 10baset into the garage

er cat5 rather
That's my plan too
this stupid linksys is a pain in the arse
I have WRT54G but I haven't got a card for the computer yet.
like this? http://22.214.171.124:10000/projects/ethernetcable/allpix4.php
No sure if they work with linux
the big bad $6 network?
wireless is for people who don't have power tools like this! http://126.96.36.199:10000/projects/ethernetcable/p1060002.jpg
How much romex can you wrap around that thing when drilling through walls?
Hopefully, that side of the house doesn't get too much sun
SWPadnos not that it does but why not? wire was only $6 been there for few years now already
well - it may last forever, but it's unlikely that a molded patch cable is rated for outdoor use
(like UV and heat/cool cycles)
SWPadnos so far it has not mattered
YMMV, as they say :)
it's the north side of the house
When/if it fail all he has to do is use it to pull another $6 cord throught :)
right - a lot easier than running conduit (though that's not too hard on the outside of the house)
SWPadnos it is on my house i got about 2 feet to work with over there ladder gets a bit steep at that pitch
how far is the drop (it looks like 15 or so feet)?
SWPadnos it's about 22 feet
hmmm - that's $3.75 inconduit, plus a couple of dollars for elbows and hangers - if there's a Home Depot nearby.
SWPadnos here's a pic of another time I scaffolded it for another job http://188.8.131.52:10000/projects/soffit/LastCorner/LC-004.jpg
when / if the cable fails, just put in a conduit when you replace it.
anyone used the Vital card?
SWPadnos nah I got a better idea I'm moving ?)
even better - a caulk gun should do it :)
I've had wires on the side of that house for like 25 years that have held up
so the cat5 should be OK
yep - I'd expect so - you don't have big snow problems, do you? :)
have had 4 feet but that's rare
4 feet total or in one storm?
4 foot one go
well - that's significant ;)
it was something
had fun with my 4WD truck in that!
was up to the hood
yeah - I've seen minivans totally buried
when it crusted i couldn't even get through it then
(I knew they were there, and there was a bit of the shape in the snow)
but when it was powder i could drive through it
SWPadnos is now known as SWP_Away
nah, more for those that dont have fishtape and 6' drillbits
CAT5 uv/water proof http://metrix.net/metrix/products/ethernet/MET-CAT5-OB-50.html
you could run EMT and pressurized it too.
10 psi should to the trick
$30! man for that i can get like 5 wires
and that's only 50 foot
well, it is OUTDOOR cat5, what ya expect =)
my wire has been outdoors lets see
I'm in California, what do I care about snow?! lol
64 bytes from 192.168.0.4: icmp_seq=2 ttl=64 time=0.687 ms
yup it's working :)
fine get CAT6 then, eeeesh =)

* robin_sz decides to go out and play lasers, again.
heh - I'm just reading your posts on CCED about selling some lasers
all gone apart from the Elctrox now .. I think
too small :)
yeah, 100W is cardboard and wood really
we tested our �2 laser goggles yesterday
work well at 1.064nm
I just followed the eBay link you had - it's a 3kW audio amp ?!?
there was a repost with a correction
yep - just noticed it (but that one has the ever-present word-wrap problem :) )
just search ebay.co.uk for electrox
Nice amp though
not at the moment
oh well, you know where to ask
yeah - thanks :)
this is how I have an audio-amp involvment
my mate andy builds them,
we cut the cases on my laser
I could use some lighting stuff though
oh that, we just buy it in from China
theres piles and piles of it in the unit
well - I'm helping out on some effects for a play, and we need several multicolor light sources
plus sparkly things
its cheap these days
sometimes. I saw a Color Kinetics board at ESC
we make like 20% in it .. but it just comes in in crates, goes out on ebay
it's around $500, and it's just 18 Luxeon LEDs, plus a little circuitry
very nice - damned bright
The LED cost is around $110
when you say "board" you mean lighting control desk?
No - a circuit board with large LEDs on it
But it is DMX controllable
[13:38:43] <SWPadnos> http://colorkinetics.com/products/oem/dle/c101/
looks liek something useful in a hug TV screen
well - it's more for area "mood" lighting
I did a maintenance course on Rank-Strand Galaxy desks once ...
it's bright enough that you can easily see the beam when you shine it on the ceiling of a very well-lit convention hall
we had a 768 channel Galaxy that needed lots of care and feeding.
yeah, I have some of those 1w modules
right - put 18 of them on a baord, and you REALLY have a flashlight ;)
Hey. Good to be home?
yes - after arriving at 2:00 AM, and then not getting my luggage for an extra 2 days, it's nice :)
Did you ever receive the CDs I (finally) sent?
Not yet. Perhaps in today's mail if the postman has his snowshoes.
So you saw lots of neat toys.
yes - a bunch
I particularly liked a couple of the tiny embedded PCs
Compatable with EMC?
there wasn't too much (at a reasonable price) that could deal with real I/O though
should be - everyone and their brother was touting Linux compatibility
That is an issue.
Well - real as in optoisolated, protected I/O - not a lack of ports
InfoWorld had an interesting column on serial communication last week.
there was actually one that had a Phoenix terminal header for some of the I/Os
(on the outside of the case)
I liked on particular one for my application, not necessarily for EMC:
It's a 300MHz Geode processor, 256M DDR RAM, has a parallel, serial, dual USB, dual 10/100 ethernet, and is in a small fanless case
takes around 25 watts (5V, 5A power supply internal)
What kind of app?
Digital camera array
That sounds awesome.
the computer is around $350, complete
Oh - it also has a VGA connector, and a CF slot
Size is the primary advantage over EPIA?
for me, size and weight.
But - the cost is also very convincing
the $320-$350 includes a power supply and case
Most of the small systems are PC/104 boards or just not quite usable without some custom fitting
Yep and 104 is expensive.
this one is in an aluminum extrusion - just tap a couple of holes (or fit T-slot nuts into the slots in the case), and you're done
Sounds great if you don't need a custom PCI or ISA board.
well - there is that :)

Take a few minutes for me to config xchat for firefox.
how about the ChatZilla extension?
there's a firefox/mozilla extension called ChatZilla - I'm using it right now
It's their IRC client
Oh that. I suppose I could.
either way - there's a lot of good stuff here: http://extensionroom.mozdev.org/
Got the config. I guess there's a lot of stuff at mozdev
yes there is :)
A really cool company I found is a PCB manufacturer in Ireland
Order 10 boards, and it's $0.83 / sq.in. At 50 boards, it's $0.35/sq.in. Flat rate shipping of $25.00
soldermask and silkscreen included.
Not bad at all.
Even if not, they charge $12.50 for the screen, and they do all the boards for that single fee
Nice. I used pcbexpress for the last batch.
So if the standard is one side silk, and you really want the second side, the lot costs an extra $12.50
Got a link?
I've never used them (unless that's the low-cost side of 4PCB / Advanced Circuits)
[14:17:58] <SWPadnos> http://www.pcb-pool.com/ppuk/info.html
* anonimasu yawns
they're in ireland but charge in USD?
They ship anywhere
(anywhere-ish, at least)
hm time to weld some alu :)
the only boardhouse I've used was custompcb.com, they're in asia somewhere. now I get to use cradek's machine, which is cheap with fast turnaround.
I've used Advanced circuits, and have never been disappointed. Lots more expensive than a local CNC though :)
(but has soldermask and silkscreen)
yeah, I wouldn't mind having soldermask and thru-plated holes as an option (well, I stay away from 2-sided boards to avoid the error-prone process of flipping and aligning the board anyway)
There are a couple of options from Advanced circuits: "$33 each" special - order 3 boards, $33 each (up to 60 sq. in, 2-side, plated through, soldermask, single silkscreen)
They also have "Bare Bones" - $0.55/sq. in. + $35/lot, plated through, no mask or legend
if alex shows up tell him I am looking for him
Ok (if I remember :) )

Hmmm - Mozilla's geting weird - see ya in a bit
I am cad drawing a part now
oopss... dropped an "i"
can someone tell me if i can run BDI-4.18 on fedora core 3 ?
You mean mix'n'match packages from Red Hat & Debian ?
lol no.... i just don t feel like formating my hdandoingtheprocess al again
OK, so you have the HD set up with a linux partition, and you want to install on that...?
well all my hd is in linux fedora core 3
is Debian any good ? seem old to me Fedora seem more up to date
what do you mean with up to date?
How bleeding edge do you want to go ?
do you mean a new kernel(unstable) or do you mean the latest software/packages?
fedora is essentially unuseable
(use "experimental" for the seriously bleedng edge packages..)
so you guys are saying that debian is better than FC3
I don't judge...
with debian I am happy to upgrade a package, with some certainty it will work afterwards, with fedora, there is at least a 10% chance it will be broken
Ido, because I ahve used both, and I would not put fedora on a production machine.
If FC3 suits the way you want to work, Debian might seam a little strange.
and fedora's 6 month life-cycle is too short for me
i just want to controle 3axes motors(stepper) so what u u guys suggest
Under linux, you only have one real choice.
witch is ....
lol dahh...... (feel like a dumb)
there's always White Box Linux and at least one other group who repackages RHEL for free
that has a longer product cycle than FC
BDI installs easily and pretty quickly (roughly 30-45 minutes from start to finish)
Upgrading to the latest packages (apt-get dist-upgrade) takes about an hour with a DSL connection
klinkz: for simplicity, grab one of the "BDI" install disks, it puts on a debian-like system and emc all in one hit
as a person who had used redhat/fedora for 6 years or so, I did have a little trouble getting used to the different locations for config files, but debian sarge, bdi-live and knoppix (all debian-based) are fine distributions
holy cow, I've been using linux for over 12 years now
i got BDI 4.18 will it install also debian ?
BDI is just debian with emc bundled :)
more or less
(Morphix, I think :) )
bdi has a different installer and different packages installed by default
bdi-live was based on morphix, but I don't think bdi 4.xx is.
Both BDI-4.xx and BDI-Live are 99% Deban when installed.
What's the other 10 Meg?
well ok you guys are the pro i ll go format my system in debian see you guys in an hour or so thanx
EMC and "stuff"
klinkz: good luck
klinkz: The BDI disk does it all for you.
ok thanx guyz
assuming someone did just grab debain Sarge by a net-install or whatver and add the appropriate line to the sources.list, will a apt-get install emc do everything needed?
thats nice :)
mmm .. les newells "sheetcam" is hsaping up nicely
[19:20:12] <jepler> http://www.sheetcam.com/
? Looks interesting.
too bad it's not free
oh it's windows? hmm.
well, I dont mind paying for things that work
as long as the price is right
of course, I would prefer an opensource one, but ... for now, thats works fine, and the price is very competetive
and being on windows is a plus-point for me, as most of my users will just be able to use their windows laptop or whatever and plug into a G200X with usb
from their, the emc interpreter takes over and crunches the gcode
that part is all open-source of course.
I downloaded glade and worked with it a while today.
I didn't see any font size or definitions
hi all i back with debain wow
well lock like the cpu got some extra speed
wow do u install xine with this distr
who do you install Xine with debian
xine is a package.
apt-get install xine
or to find stuff related do:
apt-cache search xine
localhost:~# apt-get install xine
Reading Package Lists... Done
Building Dependency Tree... Done
E: Couldn't find package xine
xine-ui is a front end to it.
localhost:~# cat /etc/apt/source.list
cat: /etc/apt/source.list: No such file or directory
(here, the tab key is your friend :) )
# The main repository for Debian packages.
# Synergy updates.
# At some point, a repository will have to be created
# for BDI related packages. Meanwhile, a dummy line..
## deb http://emc.repository/debian
sudo apt-get update
sudo apt-get install xine-ui
it work now i can watch moviez at work :)
rayh: Don't know how you would manage fonts in Gtk
I like the developer in qt much better.
What is your "gui" impressions?
I can see a Qt GUI being a damned powerfull front end...
So can I. The number of widgets and variety of connections is huge.
cutting and pasting between apps, even embedding a wp in the GUI...
being able to print out a backplot (if such a thing is built in)
The downside is who is going to code it...
cant we get the original Qt gui from nist?
I can handle the widget setup but i'd need help with sigs and slots.
If I get a .ui file for the example you wrote, would you be able to tell me how and what to do to connect it in.
the sigs & slots I can help with.
Let me work up a .ui here real quick and send.
I'll use qlabel rather than qlcd so that I can see various text combos and such.
I hacked it up to use QLineEdit...
Really. Okay. can you send that to me.
I guess what I'm most curious about is getting a designer file together with a libqtemc of some sort.
lemme add a few comments...
I'll be interested to see how that works out .. I sort of understand slots and signals, but I'll be intrested to see how the transaltion to/from NML messages works
so more qt talk eh?
I dont want to say nothing, dont want to get into trouble :)
rayh seems to be enjoying it anyway
I love qt
yeah, its quite neat.
I think its the best solution we have right now
ive talked about it lots in the past
but I cant code, so anything I say is pretty much usless
Well then all we have to do is figure out how to make it work easily for us.
and it might make multi-platofrm GUIs possible without extreme pain
if I got in on the ground floor of development with qt, I can bet you that I would quickly learn how to program in terms of with emc and qt its self
I looking at existing code i become quickly lost, but with something that I can watch grow each day, whooohoooo, but im dreaming I guess
perhaps we'll see a Sherline with a 'headless' EMC box, and a networked Qt based GUI on the users 'doze laptop
qt will help with a cross over to qnx as well
robin_sz : you have never heard of qnx?
rayh: On it's way.
robin_sz : its a real time os
qnx is neat.
robin_sz : its really cool
they run it at some telephone booths..
the webbrowser ones
rayh, paul : could I get involved with the qt stuff?
There used to be a bootable floppy disk demo of QNX with their GUI (Photon), and TCP/IP - it was pretty neat
hm, I need to machine a ballnut preload block..
but why do they need an rt os in a phonebooth?
SWPadnos : they also have a mini cdrom version
robin_sz : stability and ease of use
robin_sz: because it's light and stable..
yeah - not enough PCs have floppy drives these days :(
robin_sz : its more comercial
so they dont actually use an rt bit of it then?
VOIP could be considered RT
hmmm, not really
(for some values of Time)
robin_sz: I dont know.. I dont think it's a rtos..
anonimasu: well it is ...
but I havent used/heard of it for a long time..
it is an RTOS, but it doesn't have to be used in time-critical applications
QNX Software Systems. Realtime operating system software,
development tools, and services for superior embedded design
so its just a handy lightweight OS
that as a by-product has an RT layer
there was an emc port going on once upon a time i think
qnx i think ports more readaly to funky cpu choices
it is POSIX compliant, so it should port OK
but we already have linux, so .. well,
i think its more of a comercial type thing, not so open not so good
they only list ARM, MIPS, PPC, SH, and X86 as supported CPU types
hm, as far as interface that is good..
Linux has more supported CPUS
SWPadnos : true but linux doesnt fit on a chip in the same ways
and uClinux adds even more
no - you need 2-4M of ROM to get a good embedded Linux system
* robin_sz throws gezr a blackfin DSP board
im not touting qnx, was just mentioning it, Ide rather see it mentioned then windows :)
but I like windows!
I could have said bsd :)
netbsd, specifically :)
you know I like windows too
for "users" im afraid its still the dominant choice
will be for some time yet too
yeah I cant argue against that, I dont think anyone can
netbsd rocks ;)
if I had a eeprom burner I'd run it on my toaster
cant your toaster load it via bootp?
nope, no ethernet
Motorola S-Records, then?
its probably a token-ring toaster
back in the early days, there was concern that ethernet was non-deterministic
token ring soesnt suffer from that
qnx is a microkernel system rather than a monolithic kernel.
It is rock solid and use on many mission critical aps.
rayh, paul_c: what's the discussion of Qt about? (configuration, GUI, etc?)
I could license it for EMC for about $90 each processor
well thats that dead then
It did have tickle available so it could run just the way we do.
but well running linux and running the gui remotely isnt a large problem :)
running a remote gui is almost trivial as long as we save NML.
nml as a concept is fine
its the implentation that sucks in places
I don't disagree with that at all.
You can just run the GUI on the EMC machine, and use the remote display capabilities of X
not the most efficient way
(though the network overhead is likely higher)
* robin_sz nods
Could but that means a more powerful pc for the base box.
Nope - but it works fine on my 10/100 network
I have a Celeron 500 as the controller
I've done it here between Athalons.
My other PC is an Athlon :)
again, for the average say, myhtiical sherline user
well, running the gui on the same box as the motion part, is slow.
(actually, all my other PCs are Athlons, except the laptop)
he/she'll have a windows based laptop or desktop
But why not allow as how a 100 pll can serve as the black box.
X, cygwin, ssh .. .
Right - I have Cygwin/X - I run EMC on the C500, and view it on the 1800XP/Win2k box
of course that is dangerous
if the Linux zealots catch you, it's probably a hanging offence ;))
* anonimasu is a cnc zealot
yeah, the one true way
paul ran a tkemc on win 2k to a black box running a machine at NAMES a couple years ago.
I dont care as long as my machine will run nicely with it..
Using the nml server.
I wonder if I can get this Fox toolkit thing to compile on 'doze?
should I try Borland Builder or MS Visual Studio?
I could run the gui on a dos box.. it dosent matter that much..
What version of Builder?
I think ...
Hmmm - I've never had great luck importing VS projects with Builder. It's supposed to be better now. (I have 5, not 6)
I need to check what my helpful neighbour has for me :)
he regulalry hand me new, unopened full-release versions of things ... seems his company just buys him far too much of everything
need my address?
another successful day of accomplishing very little
"Consistently sets low goals, and fails to achieve them"
well... doesn't help when a pretty face askes me to go out.
I can imagine
but then, you accomplished *something*, right?
that's a accomplishment
"Went out with pretty face" - check
everyone has a purpose in life
well... that took me about 15 minutes to actually do what I needed to do for a whole day.
deep thoughts, with Robin Szemeti
hav you considered the purpose of yuor life might simply be to serve as a warning to others?
I remember a bigger, older guy we used to call "Dad"
I guess some things just never leave you
* robin_sz nods
hate how apache doesn't release the a folder.
I can't rename it.
linux is also on here...
but my nice tools are on windows.
It's probably not Apache - I get that type of problem just using explorer
try logging out then back in - it probably won't work, but it might
no, it's apache.
I'm using sys internals tool... "handle" and tells me what's having what open.
It's a problem endemic to Windows - Apache is triggering it (if you close Apache and any files are left in use, it's not Apache's fault :) )
no, if I close apache, or restart it, it's fine.
stop blaming windows... even though it's bad... it's Apache's fault.
Ah - the it is apache's fault :)
I know how to fix it
nope ... run apache on linux, put the folder on the linux box, share it with the doze machine with samba
apache on doze is hmm still a bit "experimental"
hm maybe I should machine somthing..
or maybe not..
wow... that took me all of ... oh... 45 minutes.
damn. I'm quick when I need to be.
well... this is fun!
archiving an a website from the FTP server... TONS of little files. :/
robin_sz: windows is still experimental
A-L-P-H-A: using wget?
damn, wished I had shell access to that box... TAR is up... and download it.
robin_sz, no... just using an nice FTP client, it had to spider all the folders, and then download it.
it's only 19megs... but still thousands of files.
FileZilla is a very very nice FREE ftp client.
pretty polished for OSS.
I prefer wget, thanks
a fellow Canuck!
robin_sz, to each their own. :)
wget -r ftp://some.site.com/pub/
login, control-A, drop and drop.
how do I define a password and login with wget?
[22:32:14] <Jymmm> http://nilno.com/laser_dir/pics/processing_head.jpg
from the man page:
The usage of FTP is as simple. Wget will take care of login and password.
I guess it asks you
ooh, funny laser torch
with a micrometer for setting the height?
cutting head for the laser
ahh, OK, the micrometer is for focus, not height
set it once and forget it/
I dont see any height sensign gear though
cant you just focus on somthing and then adjust it in software..
err calc it..
is this off a paper/wood laser?
calc it? how?
* robin_sz hands anonimasu a sheet of bent and wobbly steel
all steel cutting lasers use a capacitive height sensor ...
image recognition and a filter?
or a height sensor..
usually by precitiec
damn I cant type
will hold to +-0.2mm during cutting
how small is 0.0001" it's 0.025mm isnt it?
basically its a free-running oscillator, the cutting tip and the metal form a capacitive plate
you just try and keep a particular frequency
* anonimasu has trouble with " always
"one tenth of a thou"
yeah.. that's more like it.
.0001" = .00254mm
a typical hair is .007" in dia
the thickness of a piece of printer paper 20lb type is .004"
somwhere around that..
Jymmm, what si that picture of?
a cigarette packs celophane wrapper is about .001 or so in thickness
I use thoose when zeroing my parts(paper)
it's close enough, for most stuff..
A-L-P-H-A cutting head for the laser
[22:44:53] <Jymmm> http://www.nilno.com/laser_intro/optics.html
only 20w laser though
to adj the focusing beam I believe
20w isnt a laser, its a bright LED ;)
[22:46:14] <robin_sz> http://nilno.com/laser_dir/luxar.html
[22:46:36] <Jymmm> http://www.nilno.com/laser_intro/laser_head.html
see 100 watt
paul_c: no luck with 4.20 install... I did a basic ubuntu install and then installed the kernel and emc.... working as we speak... I have a step by step log if you would like to add it to the wiki
ah yes ...
hmm .. coherent nice.
thats a pulse laser too, which explains how he got it to cut 3mm steel
coherent dont even make liquid cooled anymore tha tI know of
and emc powered too.
not sure, but when I talked to them they were pushing air cooled
their K series and GEM series are both water cooled
hopefully this guy will take my 450W ferranti on Wednesday
another fine project for someone :)
actually. me too.
hi all, just installed BDi 4.18 is it normal that i don<t have any audio can some one help plz?
Never used sound with BDI-4.xx
I think the intro to optics page has a typo
He says you need 1550 W / mm^2 to cut steel, then says that a 100W laser has that power density if the spot is 0.645 mm^2
I think that should 0.0645 (100 / 1550 is roughly 1/15, which is 0.066 or so)
He does get the spot size correct for 0.06... so all is not lost
