will have to get one of the lab rats to finish this off
Did a apt update of emc to my 'old' machine, to try quickstep out
Celeron 450, lowest freqmod period I could get was 0.0000225
With which I could not use Axis
With quickstep, just for kicks I set PERIOD down to 0.00001
No problem! Tk gui and system very responsive
however, Axis won't work - gives an error about rs274 and exits
so, I'm going to try first downgrading python2.3-axis from 1.2.1-1 back to what it was before
it's a PITA...I can either have my parport card in, or my ethernet
apt-zip and floppies, anyone?
Cool, I still had a cd-r with a mirror of the bdi update on it
Yep, downgrade Axis to 1.1+cvs20051221, and it works again
asdfqwega: I'm sorry to hear that. Because I don't have regular access to a BDI4 system I rely on paul_c to make sure the packages work before he puts them online.
asdfqwega: If you want to /msg me with the error I'll try to help, but there may not be much I can do since it's such a PITA to build axis on bdi4emc.
I just changed my settings so I can get messages from unregistered users
10,000 spammers suddenly jump on jepler
Well, let me switch it back so I can log the error
now, if I can just find the itty bitty USB memstick so I can transfer the log...
03jepler 07HEAD * 10documents/lyx/emc2/hal_show.lyx: make image paths relative
if the computers are nearby it might be OK to transcribe the lines. I'd want the lines starting with "Traceback (most recent call last):", the paths and line numbers, and then the error message itself.
be back in a few ...
I knew you'd send me the error the moment I said I was leaving :)
unfortunately, I'm none the wiser about the cause of the problem
can you tell me the version of the emc package you have installed?
1.2.1-1 gives the error
that's the version of python-axis. can you tell me the version of the emc package too?
something like 1.0-45 maybe
yes, that's it
If you type this at the command prompt, do you get a similar error (the last line is the same)? python -c 'import gcode'
(slow machine, takes a while for aptitude to refresh)
I have ssh access into a bdi machine and I got the same error when I installed emc 1.0-45 and axis 1.2.1-1 (when running python -c 'import gcode')
Yes, I get the same error
The same ImportError
I think there is just some problem with the axis 1.2.1-1 deb. "_ZN7InifileC1Ev" is the name of a function that should be provided by emc but it's just not there for some reason
(it comes from a "static library" so something is wrong at the time the axis .deb is produced)
(and it's just the first of many symbols which should be present but aren't)
Time for me to call it a night
OK, I found two separate problems, both of which are specific to bdi4emc.
asdfqwega: there are two problems. The original undefined symbol error occurs because two files are listed in an incorrect order when the python 'gcode' module is created.
the second error is also an undefined symbol but it has a different and more difficult to explain cause
do you read the bdi4emc mailing list? I am going to prepare a post to it about this issue .. I don't think anyone can successfully use paul_c's latest axis .deb packages
unfortunately, paul_c doesn't supply some of the files necessary for others (i.e., me) to produce new .deb packages of axis, so I can't fix the problem myself.
(not with a new .deb that you could easily install; instead you would have to follow several steps of downloading, patching and compiling)
asdfqwega: if you're very brave, upgrade to axis 1.2 again. Then download this file, untar it, and move the 'gcode.so' file inside it to /usr/lib/python2.3/site-packages/ .. it might work, or you might have to downgrade to 1.1+cvs again.
that's all for tonight .. but watch for the mailing list post and any replies.
I've already downgraded it back, running the Chips.ngc for a screensaver :)
I'll give compiling Axis a try
if you want to do that, you'll need a patch I haven't yet prepared
you'd follow the instructions at the bottom of http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?BDI-4_38_Compile_EMC2
but before you run 'setup.py' you would apply the patch from http://emergent.unpy.net/index.cgi-files/sandbox/axis-1.2-bdi4emc.patch
am linux newbie and need help with emc failing to install
what kind of system are you trying to install it on?
Dell Optiplex GX1
do you already have linux installed?
yes, that went smoothly
maybe we should let stevec20 tell us where he's stuck
which linux? ubuntu?
ubuntu as recommended
cradek is right, tell us where you got stuck
tried the install script and is OK thru building dependency tree
then it says some packages not installed.
did you have a network connection during the ubuntu install, or did you set it up afterward?
set it up afterward
ok this is a known problem, it means you need to enable some repositories so your system can download the necessary packages from the ubuntu servers
now, in english.....
jmkasunich: do you know how to turn on those repositories with synaptic? I only know how to edit the sources.list
ok please translate for me
I edited sources.list, but lemme look
text editing i can do
synaptic is pretty easy tho
are you familiar with any of the editors on your ubuntu system?
I'm not at the right machine to look at synaptic
(dunno how long you've had it running)
gedit is easy for everyone to use
EDITOR=gedit sudoedit /etc/apt/sources.list
lets use synaptic
on the menu bar, click settings, then repositories
I have a fairly long list, yours is shorter I suspect
yes just 3
ubuntu 5.10 breezy badger (binary) on all three?
under that is a couple lines of small print
Officialy Supported / Restricted Copyright?
yes under first one
Community maintained (Universe)?
no dont see that
do any say "Updates" or "Security Updates" on the first line?
oh, just found a better way I think
click the settings button under the list
the first checkbox says "show disabled software sources"
then click close
now you should have a long list
yes - long
the little box to the left of each one tells whether it is enabled or not
you probably have three dark gray boxes (enabled) and a bunch light gray
click all the light gray ones that say "(Binary)" at the end of the title
now we need to add the special one with EMC in it
I bet that's done already if he ran the install script
is there one called dsplabs.cs.utt.ro/emc2?
there is one with emc in small print
in fact just running it again is probably the easiest way to finish the install
lets try that
so.. should i click OK and go back to install script?
click OK to get out of preferences
it might ask you about updating repository info
when its done with that, exit from synaptic
it says you must reload packages do you want to
that will take a little while (maybe a couple minutes on dialup, less on DSL)
it it downloading package list
DSL its done
exit from synaptic
and try the script again
script is taking longer - a good thing
thanks for the help
when the install finishes, you'll just have to reboot, then you can run emc
stevec20: how did you find the pointer to the emc channel for help?
from the contact page
script has finished going to reboot thanks for the help
don't hesitate to come back if you need more help
(or just want to talk about CNC ;-)
ok i will
thanks for helping him with synaptic
hmm - have you seen the halscope trace from JonE?
its simply horribly mistuned thats all
no I = no performance
he says the red trace is encoder delta - is that even possible?
don't know the scaling
(not to probe - to get that kind of waveform)
if you look at the fuzz, it looks like ~10 counts / div
he has 128000 counts per inch
if he's at 10 counts/div, then thats 25 counts or so, about 12ipm IIRC
1) does the upc/usc driver even have delta? and 2) doesn't it reset each read()
1) checking, but it must (or he's smoking even more dope that I think he is)
that was the corollary question ;)
ok. I didn't remember putting that in
delta = pos now - pos last time
last time = pos
so 2) yes
yeah, I guess
unless he's got the scope running faster than the servo thread
its basically the same as if you routed it to a ddt component
scope is sampling at the servo rate
at 1 KHz, the normal servo rate ...
I suppose someone should ask to see his hal/ini files ;)
we know input scale is set to 128000
that would be the right thing to do, tech-support wise ;)
output scale is probably _not_ set the way I would
I'm gonna reply
and even be nice about it
I think maybe I'll go to bed. I was fighting with LabView until 3:30 this morning (and again until a half hour ago, when it crashed)
what are you trying to do with it?
labview = ouch
a power supply controller for an arc machine (similar control to EDM)
using an NI CompactRio chassis
so FPGA connected to IO modules, then a realtime controller, tehn the PC
PC connected via ethernet
= big PITA
Yes, SWPadnos is a BIG PITA! =)

I should go to my doctor for some doc.. I'll go this afternoon at this point
got a picture of your cnc/lathe and a link for that ?
I'd like to add your userpic to this page http://www.giacus.org/emcstats/emc.html
I already did it for someone without ask for permission.. :(
I dont have a cnc lathe yet
on the nick there's a link to the personal website, on the pic the link to the machine

you sure? :D
GMT didn't switch to summer time
I used to be GMT+2, now I am GMT+3
it's summertime here now :)
yeah, but GMT doesn't have summertime
might be true
yep they dotn
so you're GMT+2
confusing as hell
windows tells me +1 ;)
but it tweaks the timezones(summertime)
yup.. so does mine.. stupid ;)
alex_joni: is a link from your userpic to http://dsplabs.utt.ro/~juve/work.php

hi les_w !
les! good morning.
what's up ?
aw, another day another dollar
I'm booked up for months
which is a good thing
haha nice theory, I like it
yeah....I get little time off though
I don't get to work on the cnc control much
I thought cnc already had control in it ;)
hehe, time to run EMC2.0.0 then :)
I am in the middle of a rewire still, and I want to try the motenc and the newer code
a bunch of stuff is on hold for me
I'm thinking to get a motenc card too
like the shop enlargement
I keep thinking a break in work will happen
but it doesn't
but I figure if the work is there...gobble it up...fill those bank accounts
I think two things are very important in the life, in first the family, after the work
les_w: I like very much 2 things: the second is to travel ..
les_w: I'm playng around this stats: http://www.giacus.org/emcstats/emc.html
can I add some pic and link from your website ?
neat! sure, links to the site are always welcome
well off to the shop now
back at midmorning break
have a fun :)
what's the internal resolution of the gecko stepper drive?
you might wonder why i ask that but that's intresting since i believe that the gecko has a finer resolution in the logics than 1/10 steps. is that true?

SkunkWorks: read the query please
are you identified to the server ?
I'm asking you if you have any personal image or weblink to use as userpic in the stats page
no - but I got your message. I will look to see what I have. Thanks
oh.. maybe I can't read you in query instead
I can usually see what people are saying to me - but I can't talk back :)
How about this? Only picture I have up. http://www.electronicsam.com/images/me.JPG
because you've not registered the nickname
How would I go about doing that?
This nickname is owned by someone else
If this is your nickname, type /msg NickServ IDENTIFY <password>
/msg nickserv register yourpassword
after that, you've to identify to the server anytime you connect it with /msg nickserv identify yourpassword
don't I have to register my name somehow with freenode initially
or does that line just work?
you can also put the appropriate command into your irc client to auto-identify anytime (without type any passwd)
I am sorry - I am really new to irc
yes, it work giving that command
choose a good passwd
so, you'll be also sure no other than you will use the nick SkunkWorks
just this command: /msg nickserv register yourpassword
one time only
and /msg nickserv identify yourpassword anytime you connect the server
SkunkWorks: can I link your nick to http://www.electronicsam.com
is it correct ?
You can link :)
giacus: have they start the huge suspention bridge between sicily to italy?
over the strait of messina
They're planning to start since 1960 ..
but when some japanese engineer seen our plan he start to cry ..
the bridge should be double of the biggest bridge of the world
lenght is more of 3000 meters
the biggest one is around 1500 mt
it has a suspention lenght 2.5 times the golden gate bridge
they will never built it, they just used that bridge as spot to get votes on politician elections
hmmmm! pretty quiet
cradek you around
can anyone tell me how to set blending?
g64p###, I Think
that's blending with tolerance ###
that makes sense..
I've not tried it and want to.
I winder if anyone at CNC workshop would want to buy a Tapmatic 90X
there must be docs someplace but I've not found them
bring it and find out
heh - it 's relatively small
you might check ebay and he an idea of going price
get an idea
which type is the 90X?
yeah. it varies quite a bit. it's big though, so many machines (including my Bridgeport) aren't really big enough for it
it's the huge one, 1/2 to 1-1/8 capacity
auto-reversing clutch type
wow..no wonder it is big
yeah - I think it exceeds the max tool weight for a BP
a bit spendy also?
they're $1100 new, I think
I should see what I spent - it wasn't anywhere near that
shaft mount or R8...or?
MT3 or MT4, I Think
but the mount is removable
in fact, it's removed right now
1" shaft would be nice
yep. it's got the threads for whatever shaft you want
the shafts are $$pricey though
oh, that makes it easier
with a good lathe you should be able to make your own.
one day, I'll have a lathe
get some acralloy shaft... 4142 normalized and ground to 16 microinch finish
I'm off to try g64 p ... thanks

all nice here around, I just back from doctor. Tomorrow I'll go for a complete check-up
doctors are doing a nice business here
next time i'll born I want to become a doctor :P
next time I'm born I want to have more social skills :D
same here. :)
but that's probably not true..
it's the env.. i grew up in..

all turn around the possession
hm, I feel good today, maybe I should go and try to finish some machining
how was sayng john lennon in his song image ?
I know the word, but what in what context?
image no possesion ?
* giacus look at the dictionary ..
I'll be back in a hour :)
sorry about just going in the middle of a convo..
talk to you later
btw, possession was right as term, it mean exactly what I want to say ..
i'm a bit a dreamer as lennon :P
that's why I think no people could live without dream a bit :D
Imagine no possessions
I wonder if you can
No need for greed or hunger
A brotherhood of man
fenn: nice, I'm able to play it with my guitar, but I don't know the mean of all word

Jymmmm: I've a problem
O_O who ?
I've been to my doctor this afternoon
I found a big difficult to explain him I agree to talk to computers, machines, and not to the peoples
any hope to get him understand that ?
I just sayd I've a nice feeling with computers, but a big difficult with the peoples
what you think about ?
no reply eh ? heheh too difficult question :P
what was the question?
why is so difficult to get a nice feeling with peoples, when not with machines ?
Oh, people suck.
humans are poorly programmed
giacus: yeah, they do. go listen to the link I posted.
doctors are notoriously difficult to use
Jymmmm: I tried, he speak too fast for me :(
FUNNY FUNNY shit
is this the starbucks coffe guy
no idea who that is
how you got it ?
I made an engraving cutter to do that. Probably buy some official ones though when I get a chance.
oh.. ok, it was seems ink to me
I can't find tose micro endmills on ebay =(
seems like you get some burrs because you have sanded id?
its a crappy picture
Yes - I had to sand it.
when using proper tools and spindle you can get very clean cuts without burrs
That is why I want to get some decent cutters. Or try to sharpen mine better.
hi giacus, any news?
SkunkWorks: looks pretty good to me
this is what I get with my router http://www.students.tut.fi/~kontkant/cont/cnc-jv2/020-bcp/4a3977proto.jpg
I am happy with it - I will probably make the official prototype with my cutter.
alex_joni: not yet .. I've to heard anna, today got a long day in office
approx: very nice. what cutter do you use?
approx: what power stage do you plan here: http://www.students.tut.fi/~kontkant/servodrive.php.html
I used the too in right in this picture http://www.students.tut.fi/~kontkant/cont/cnc-jv2/020-bcp/1tools.jpg
approx: this is my plan http://thinktink.com/stack/volumes/voli/store/mechmill.htm
Cradek has had good luck with them
closer look on traces http://dal.ton.tut.fi/a3977proto2.jpg
I have some similar looking tools made by VHF
I haven't used them much yet
alex_joni: I'm going to use discrete mosefet power stage
approx: what is the narrowest isolation you can cut?
i wonder if a negative rake engraving cutter would help reduce burs
not sure about that. depends on tool. I guess 0.3 mm can be done
approx: what voltage? are you using the surplus center p5 motors?
yes, P5's. I probably use 200V mosfets
aw crap they raised the price on the power module i was thinking of using
[17:48:21] <fenn> http://www.fairchildsemi.com/pf/FS/FSBB15CH60.html
<- used to be $12
and only in 1000 piece quantities
digikey has them for $16.35 in qty 1 (am i reading that right?)
fenn: are you planning to build a servo drive?
well i've got 6 of these 400W p5's
think i will use icee's design since i'm pretty familiar with it
please build an AC servodrive !
[17:56:01] <fenn> http://forums.donniebarnes.com/viewtopic.php?t=52
anyway gotta make my desktop version with little brushed servos first
looks promising AC drive plan
any boards assembled yet?
damn damn damn i gotta make this jameco order
* fenn shuts up
high priced bastards
they have a good website and good pricing and good selection
you are probably sour from trying to order avr's from them
but did you know digikey is atmel's main supplier?
No, Jameco is (was) based here in San Jose, I used to hit the retail store all the time, the prices were always high. When I looked at the website last month, I wasn't impressed with their pricing.
well they have the best deal in town on rj45 jacks
you tried halsted?
$0.39 top entry $0.48 side entry
no and i dont care

fenn: I remember the 3 phase drive that larance was building. Do they actually have one running using the pico driver?
i havent heard from him in months
i think the last thing he said here was posting the url to that wiki, which hasnt changed either
so, maybe he zapped himself )
ewww. burnt hair
well I can't wait to get one axis running and seeing how a brushed servo runs only using emc as the feedback.
yes I am a cheap bastard.
let us know - i for one am interested
hm, I finally started making motor mounts
SkunkWorks: how do you connect encoders to PC? some additional interface?
It has been done - jmk first - and now jepler is doing something similar.
I need a cnc machine, I'll die without one soon
for his etche -o-sketch
approx: either a servo card or parport & software counting
approx: right now the encoders will be hooked into the parrallel port
is there enough inputs in parallel port?
approx: most servo cards have counter chips (like LS7166)
approx: for 2-3 axes sure
or get a second parport
and outputs too?
for what I need 2 will be fine.
I have been looking for PCI card for second parport but haven't found yet
If I get that far.
one parallel port can't do more than 2 axes: you need 2 outputs and 2 inputs per axis
if it works well I will then probably get a fpga
where to get additional parports?
SkunkWorks: if it works well, get more parport cards, fool!
Jymmmm: query ..
fpga's are friggin expensive
fenn: my mind went blank - its like 300 dollars and does pwm out and encoders in - field programmable array
PCI parallel port cards: http://froogle.google.com/froogle?btnG=Search&price1=&price2=25&btnP=Go&q=parallel+port+pci&lmode=online&cat=1370&lnk=catsugg
my wife loves froogle.
how fast encoder counting I get with emc2? same as stepping frequency?
wouldnt it be faster because you dont have to worry about time quantization
I have some linear encoders.. would like to try dual loop feedback :)
i mean you should be able to go right up to 1/2 base period
er, 2x base period
* fenn doesnt know what he's talking about, so please correct
you can have at most one quadrature "edge" per base_period
that's assuming the signal is completely clean
well you should be filtering it anyway
some encoders are specified in cycles of 4 edges
approx: dual loop is usually bad ;)
and you can do some minimal glitch detection, the motor wont just spontaneously reverse direction
approx: unstable, and hard to tune
unless you have a velocity loop & a position loop over that
I tried linear encoder PID loop it with some AVR hack. worked nicely
that works, but having two loops of the same kind one inside the other is hard
I used encoder feedback to a gecko and to emc once, didn't quite work perfectly
I tried linear encoders with steppers. no problems at all
I don't see why servos would be any worse
approx: explain the linear encoders with steppers
linear encoder mounted on machine axis. stepper driven by step pulses
ok, but don't use pid on it
yes, I had PID on avr
pid works just the other way around that steppers want it
if your system misses a step, pid will make it go faster, and that only will make the motors stall
yes, motors still can stall but it can be detected
alex_joni: heh so use a negative P :P
linear encoder is there just to eliminate backlash and mechanical errors. not to make steppers run like servos
approx: right, that's why I said don't use PID
is there better methods for this?
approx: you should use the linear encoder as position feedback only
but why not to use PID to correct position?
maybe some small pid too, but with a small P
when you notice a stall, turn the feed rate way down and then slowly ramp it back up to unstall the motor.
jepler: or simply stop ;)
wouldn't you get a following error first?
SkunkWorks: depends how it's tuned
I guess you have to have a way to inject the missed steps before you start feeding normally again
PID will do that for you
straw idea: don't give following errors during G0 moves. It's not a coordinated move anyway, so it doesn't matter if you leave the idealized path from start to finish as long as you arrive at the end.
in fact, just put the end position as the commanded position and let pid or stepgen sort it out
approx: are you curious or just asking too many questions?
why can't there be a "self tuning" utility in emc?
I thought there was one initially - but it got lost along the way
SkunkWorks: I think It's hard
approx: for steppers, the better way is to not use PID at all.
but there's a reason
If you tune it by hand using halscope - I would think the computer could do it better than me.
the issue is to get a machine to think as a human
as much is possible
sometime, is it not so possible
that's the reason
we are always better
and the machine is always stupid
and its right so
I don't know enough about servo tuning to believe it's impossible for a computer to do it.
sure seems possible.
this is what I remember reading http://emc.sourceforge.net/Handbook/node38.html
then another one saying the script was lost.
there are plenty of known methods for automated PID tuning. it would like to have one in emc too
seems like it was a start anyway
any tuning software written back in 2000 is unlikely to work with emc2, even if we could find it
but the algorithm would still work and be easy to reimplement with hal
yeah just measure the acceleration curve of the motor
just a simple matter of programming
I've been looking around for a stepper moter driver board, at a good price. Any suggestion besides the ones listed on linuxcnc wiki?
right, and the PID gaines "can be deduced" from that, just another SMOP
(if possible, a board which has actually been tested with emc)
strav: are you shooting for minimum cost at any cost? or something that will work reliably at decent speeds?
i could point you to a $20 board that might not work for your application
My goal is actually only to practice sync motors so I merely need a toy driver.
(best deal I found was at site called stepper world)
fenn: does it at least can enable half-step or micro-steps?
I must precise: I'm looking for one which has already 3 axis implemented.
hmm actually nevermind, forget about that board
:) you're not a very aggressive person
if you want a "toy" driver, use the ULN2803, one per axis (or parallel more chips for more current). It does half-stepping. 2 axis version: http://axis.unpy.net/files/etchcnc/etch-schematic.png
jepler: unipolar only, right ?
the good: ULN2803 is a dollar apiecce or so. the bad: unipolar, L/R is the worst design in terms of max speed
it is great to control a webcam in remote
cheap and good
in theory you could have emc generate a microstepping waveform .. that would be the height of silliness, though.
jepler: I'd be glad to try out building it from scratch though the only thing I I want to avoid is encarving the board myself. Do you happend to sell pre-encarved boards?
wow $0.69 each for uln2803
I bought it as stock
very cheap, yeah
i think i like jameco
strav: No, I don't. But it's so simple you could assemble it on perfboard if you wanted
oh, send the poor guy a board
cradek - now that I mentioned the pid auto tuning - is it going to be done? I seem to have that effect on people :)
SkunkWorks: we thought you were going to do it
* fenn cracks the whip
jepler: I wish
SkunkWorks: if you come up with the algorithm and do the math, I bet someone would do the hal part if you can't
Its like I have my own personal team of programmers _ makes me feel powerfull whoo ha ha ha ha
fenn: one has to start small... else he's a self-inflated idiot.
pff, "if you want something done right, do it yourself"
I will see what I can come up with.
strav: i forget if its on the wiki, but check out pminmo.com
[19:21:09] <SkunkWorks> http://www.pminmo.com/l297-8/l297-8.htm
nice, that's the board cradek use
there was some pretty nice setups on ebay with motors a while back. Around 100 dollars an axis if I remember right.
yep this one is on the wiki. Thing is I tought I absolutely needed to carve the board myself. (didn't had much time for checking this out, lately)
i really hate when companies remind you that they have all your personal information
what I found at stepper world was about 170$ for 3 axis integrated.
fenn: who ?
carve? as in mill or etch?
they really go on so
just selling personal informations
a right law would be nice
but politicians don't know waht the net is ! :/
skunk: well come out with the copper sheme done on board
I don't feel much like getting a used car battery and a compass kit.
[19:31:16] <alex_joni> http://video.google.com/videoplay?docid=2942922314315974986
<- that's a nice setup
huh.. The url is invalid and can't be loaded
that's an awesome video
does work here..
SWPadnos: doesn't it make you wanna cnc it?
it's already animated - what could be more CNC than that? ;)
hehe. I wonder how the guy did it. Either by sequencing the balls from the tracks or sequencing the sound from the balls.
SWPadnos: I meant for real
the air-based aiming would be hard ;)
there is a CNC guitar-like instrument I've seen
wow alex_joni nice
and I think Ray mentioned that he was working on a "player violin" some years ago
(but this suff ain't hard to do... most 3d apps have already integrated motion controllers that react to the amplitude of a sound...the only challenge is a good sound tracking to work with the controller)
i dont really see what the big deal is about that video
maybe if they actually did it in reality
* Jymmmm hands fenn his anti-crusty pills
it's well done music, and the animation is also interesting.
* fenn hands jymmm his suppositories
fenn no thanks, no need for those
* SWPadnos sends Jymmmm and fenn to the planning room
fenn: maybe this is better: http://video.google.com/videoplay?docid=4886526472898348120
gotta go. Thanks for the links, usefull or not.
Jymmmm: did u read the query ?
how much FW are you using ? :((
alex_joni: hmm i had that movie but deleted it on accident before i got to watch it
SWPadnos: Any thoughts on these? http://cgi.ebay.com/50X-NEW-3mm-WHITE-LED-LAMP-WIDE-VIEWING-ANGLE-18-000mcd_W0QQitemZ7617357065QQcategoryZ66948QQssPageNameZWDVWQQrdZ1QQcmdZViewItem
what a POS switch this is, and it's $30!
coworker has the animusic dvd
SkunkWorks how is it?
I would watch it once :)
Jymmmm: I was calling you
giacus I dont understand what your saying/asking of me
I was queryng you
he is trying to talk to you in a different irc window
alex_joni: I seen time ago a robot palyng a flute
can't find the video right now
I remember the robot playing a flute
but was very nice
can't find the url
Jymmmm, those should output somewhere around 75% of the luminous flux that the 135000 mcd ones do
unless the 10mm vs. 5mm size makes a difference
if so, then the big ones are ~5x more "flux-y"
that's assuming that the big ones are 12 degrees, which is what I think I remember from our previous conversation
the way I calculated that was to take sin(angle)^2 * mcd rating
the sin^2 function gives you a number proportional to spot size. multiplying by brightness (intensity) gives a number that should be proportional to total luminous flux output
here are the 2 "servos" I will be playing with. http://www.electronicsam.com/images/KandT/SERVO.JPG
it has an integrated encoder - I have not played with it yet - I hope to use it.
[19:54:07] <SkunkWorks> http://www.electronicsam.com/images/KandT/SERENC.JPG
you there ?
they are out of old line printers - but it gives me something small to play with.
line printers rule
SkunkWorks: you coming to the cnc-workshop>
the last 3 days
cradek talked me into it.
is that a temperature sensor?
K4ts: any news from antonietta ?
Fenn: Are you talking to me? that is the encoder on the back of the motor. You can see the disk.
(little out of focus)
K4ts: novità da antonietta ?
could you please ask then ?
i meant the white/red wire with red goo on it
K4ts: ask her and let me know
SkunkWorks: oh heh, nevermind
* giacus give K4ts a big english dictionary :P
sto parlando al telefono
con la prprietaria
she's busy to phone ..
we actually had the line printers for a while before we took them apart. You could put them into a test mode and it would print out the ascii charecter set. The paper would be 100% convered with text and flying out of the printer.
* giacus play mplayer 06 - Track06_Kc & The Sunshine Band.mpc
some had an hammer for each posision - and a rotating drum with the charecters
SkunkWorks: scary.. huh?
ah the good old days :)
* giacus is busy playng 06 - Track06_Kc & The Sunshine Band.mpc
hehe K4ts ! tell me all
giacus: are you making k4ts pimp out her friends?
I'm tryng ..
SWPadnos: Ah, very cool. Not TOO expensive, think I'll order them.
tonight is nervous giacus?
K4ts: did you understand what I asked you ?
mah is mad
for your house ?
yes for mounth
E. 700 /month ?
seems cheap to me :)
in the centre of naples
why do not you move into the mountains around ?
prenderla se mi piace
saputo niente di antonietta per alex ?
antonietta è in pieno trasloco
dalle una decina di giorni
fammi sapere (let me know)
she's going to wrk or not ?
alexwhait 10 day for new holiday?
ho detto se puo aspettare
if he can wait ?
we can wait
but let me know ok ?
è inutile che fai il professore ahah
sto ore intere per tradurre
alex_joni: sorry for my italien
you must say sorry for my english !!
I not have translate
is the pid in axis parrallel or series?
si innervosisce se scrivo qui in italiano
ho detto scusa per l italiano
hai sbagliato (you're worng)
dovresti dire scusa per il mio inglese ( you should say sorry for my bad english..)
* giacus died
K4ts: are you a very aggressive persone then ?!
perchè quando uno non scrive in inglese qui alex_joni si arrabbia
please anyone can explain her what I meant :(°°°
se entri in msn
que e arrabbia?
K4ts: giacus says you are a mean person!
what are you sayng ??!!
K4ts: you beat up all your boyfriends!
should I run msn ?
now asking to emacs to run msn, wait ..
let me search ..
K4ts: ok.. I'm on msn
* giacus sighs
k4ts eat ice cream spiteful for giacus
K4ts take a photo, and email it to giacus
feed it to the dog!
k4ts tirelo al cane
kira eat giacus
K4ts: ice cream not giacus
k4at smack giacus
[20:30:03] <giacus> http://www.giacus.org/files/kyra.png
that should be kyra eating me hahaha
K4ts: you're a looser
K4ts: That your puppy?
buy a doberman
ice cream yes
yes is my dog
K4ts: I dislike small dogs, but he's cute.
* giacus eat kyras at breakfast
K4ts: boot giacus!
hey guys, too much peoples beat giacus here around
warning, anything is written !
logger_aj: beat giacus up
I'm logging. I don't understand 'beat giacus up', alex_joni. Try /msg logger_aj help
* giacus loves logger_aj
love and piece brothers, stop the war :)
K4ts: sorry.. you're right, I'm wrong , I missed all
are you happy now ? :)
psss K4ts you must say YES! now ..
with a bit of late as woman usually do ..
hello, does anybody intend to record the emc class at the cnc workshop, i would like to see this if possible?
hmm last year it was sort of spontaneous
* giacus give a gift to K4ts : apt-get install ntpdate
i was tihnking about bringing a webcam but i may not get around to setting it all up
since i'd have to buy one and figure out how to use it etc
fogl: is there actually a class planned?
[20:41:06] <fogl> http://www.cnc-workshop.com/emc_schedule_notes.htm
I think ray is planning a lot of things - you should ask him about it
do you have his e-mail?
oh cool a casting workshop
dont you think it would be nice to upload these movies to emc web page?
yes but video of hours worth of classes would be a bit unmanageable
put the videos in the wiki with everything else!
Jymmmm: it's possible you've had worse ideas, but I can't think of one right now
cradek: whats to managing videos?! you shove em in a directory and let apache do what it does best!
we've got to something to use up the pace and bandwidth ;)
the wiki is on sf and can barely manage the 1k pages we type in
* alex_joni can host videos on dsplabs
shouldn't be a problem up to a few gigs
they can be put on dreamhost. I've got space and bandwidth to spare
~74G space / 2TB bandwidth
err - 2TB/month transfer
how much are the bots intelligent now ?
<giacus> what's up ?
[23:10]<giacus> I'm from italy
<giacus> you ?
<fsbot> you is, like, an ingrate who doesn't want to serve me beer.
isn't that fromt he Ali G show?
hate that show
cant find Ali G show here around .. A-L-P-H-A
giacus. you're lucky
why ? O_O
go find an ep on youtube, or google.
ah ... ok
