Phydbleep you never know, goats might like brass
:( there goes this part.
ground a lil too much?
Jymmm, no... I kinda didn't think about some stuff... so I reprositioned the part, and messed up.
I guess I "could" try and reposition the part, and see if I true it up again...
manual or cnc ?
well, that sucks
well... the material costs is maybe a few bucks.
but it was all that time I put into it today. heh.
no. cold rolled steel.
* Jymmm kicks Phydbleep in the shins! You just had to post that url didn't ya?!
didn't you learn that in highschool?
probably gonna do this too first...
I can type complete sentences. really. I can.
I graduated HS at 15
take a test and got the fuck out
took a test and got the fuck out
but I was talking about the tricks
I finished at 17.
knew a kid that was a college sophomore at 16...
also a complete loony
I don't know that shit. sophomore junior, whatever.
HS was such a PITA
wound up in a rubber room
jmkasunich, hey... that spindle was going great! till I repositioned the part.
I was machining the spindle... and didn't really think on how I was going to machine it.
I just kinda went at it...
argh. oh ohwell. buy another few feet of steel.
well, beats my progress... I'll still be planning mine 3 months from now most likely
jmkasunich sound like me... overthinking things
* jmkasunich sometimes suffers from "analysis paralysis"
jmkasunich, I'm doing what Les suggested... drill, ream, and what you suggested, use a dead centre. I just put in 1/8" drill rod into the tailstock/collet holder.
jmkasunich aka... anal cranium
yeah... engineers gotta be anal
4000 fscking parts in something, and it only takes one screwed up detail on one part to mess up the whole thing
jmkasunich, but this only has... like 6 parts.
drives you to be anal about details (or drives you to drink)
still lots of details
3 bearings, two nuts, one set screw... + housing (housing, and a locking collar probably.
jmkasunich D) All the above
ok, dumb question.... whats the middle thingy for? http://www.harborfreight.com/cpi/ctaf/Displayitem.taf?itemnumber=4185
finding the center of round stuff
say you have a 3" round bar
place the bar in the V, so the square blade crosses the end
make a mark along the blade
turn 90 deg, make another mark
this looks... interesting. http://www.harborfreight.com/cpi/ctaf/Displayitem.taf?itemnumber=4357
* jmkasunich is doing mindless stuff tonight
jmkasunich, help me design a business card holder... the ones that you put in your pocket or breif case.
* jmkasunich goes to office supply store, buys $3 business card, gives it to A-L-P-H-A
business card holder for your pocket?
oh, right... that small is probably only $1.50
[02:02:12] <A-L-P-H-A> http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&category=25338&item=4373569174&rd=1&ssPageName=WDVW
oh, you want fancy
* jmkasunich doesn't do fancy
A-L-P-H-A make one that automagicalyl dispenses the card
push a hidden button and a single card pops out
press it twice and the card pops out at Mach 2 and delivers lethal paper cuts (James Bond's card holder)
I think you two need to get out more.
my business cards live in the box than came in. Approx 5% of my visitors get cards, cause the rest of the time I don't have any on me
* jmkasunich would be a lousy salesman
jmkasunich no no you silly bitch... nut a paper cut... a razor edge throwing star!
jmkasunich your kung fu is no good!
but then its no longer a _business_ _card_ _dispenser_
jmkasunich what do you think is printed on the stars?!
Mr Chows Chinese Fast Food and House of Ninjas!
I have seen steel business cards before
I got an aluminum one
from a metal supplier
the steel was from an electro-chemical etch house
about 0.007 thick, with patterns etched into it
(holes, slots, etc)
stainless I think
that sounds cool
you can laser etch SS
even make it have different colors too
now those cards would be EXPENSIVE. :(
yay! second batch of parts done, only one more to go
A-L-P-H-A Here ya go ---> http://www.color-laser-engraver.com/what.htm
looks like the same princple that gives tempering colors
(straw, blue, etc)
at least somebody here is honest about it
How's it going?
well, it is around midnite, eastern time
the 45 minute deburring/cleanup job I started an hour and a half ago still isn't done
IRC can't possibly have anything to do with that, can ti?
haha, of course not ;)
Jymmm is now known as MrAsshole
MrAsshole is now known as Jymmm

* jmkasunich wonders how old Jymmm is?
Heh, they just reflect my current state of mind.
food and then sleep. I think.
"creative" nick = young (20's maybe)... some variation on real name = old (40+)
* Ircaddict munches on a bag of doritos
btw "Revelations" is on
whatever that is.
some TV show
Yeah... but its 2 of 6, and I missed the first episode
hmm, maybe taking that nap at 1900 wasn't a good idea with me havving class in the morning
class? what's that?
jmkasunich, hey! think If I got a collet extension, put a groove into it, put a C or E clip on it, and thread the tail end? and shove a space inbetween to keep the bearings equally spaced?
definitely a time where a pic is worth 1000 words
jmkasunich: something which leads people to believe that by paying money, it will get them money eventually
that's something like work, except you pay them instead of the other way around?
jmkasunich, pass me your email, after I draw it up, I'll email it?
(and you are more likely to be able to cut and get away with it)
er, something like that, only they make you think you can get work
what kind of classes?
well, tomorrow it's just physics
engineering, medicine, law, or "fries with that"?
But i'm going to the Great Lakes Maritime Academy
basicly training to work on all the mechanical aspects of a ship
which lake is that on? (I'm in cleveland)
that being said, i probably won't work on a ship after i get out, but all that stuff is transferable
the school is up in Traverse City
over the summer I was in cleveland quite a bit on the Fred R. White Jr.
did a few runs up the cuyahoga
the name sounded familiar
I kinda found it humorous that people would actually jet ski in that river :)
It's an oglebay boat
enough alcohol, and people will jet ski anywhere
friend of mine worked a summer on an ore boat long time ago (he was in college at the time, he's over 50 now)
one of those "nice experience, but wouldn't want to do it all the time" type jobs, according to him
yeah, it definately takes someone who can keep themselves occupied
they have internet on the boats these days?
on the upside, you are at a dock pretty much every other day
naw, but they got sat. tv
when my buddy was working on the boat, they kept him busy...
hehe, oh, there is work to do
started painting at the front, by the time he made it to the back, it was time to start the front again
paint, paint, paint
I didn't have to do any painting :D
I just worked on CATs, EMDs, piping, pumps, and other stuff
did a bit of welding as well
Ircaddict, hacks prime movers
cool, actual stuff that requires a brain...
my buddy was strictly treated as a warm lump
most deck hands are like that
it was pretty fun though
cured him of any desire to be a deckhand for sure ... he became a manufacturing engineer
I'm probably gonna follow the path of my dad
he went to the Maritime Academy (engine program as well), got his license
but never sailed a day in his life on it
now he owns his own gig selling CCTV equipment
I'm finding myself leaning more towards the business end of things as well. Currently I'm looking at the prospect of starting up a manufactring gig here
I'm not much of a machinist myself (Interested as hell in it, i just suck at manual machining), but I have a few friends who are rather well versed
it's tough to make a go of it
gotta have something special that you can do and others can't
That is correct
I have a day job that pays all the bills, so my machining biz can be _very_ part time
actually, what i'd really like to do, is turn that into an engineering operation
I'm finishing some parts up for a customer as we speak
I'd like to get into the firearms and aftermarket parts industry for cars and bikes
(just filing off burs, etc on waterjet cut parts)
Ircaddict aftermarket phalix installations
^ and slaes
pay no attention to Jymmm
Ircaddict mounted on car roofs --> http://www.chinfo.navy.mil/navpalib/factfile/weapons/wep-phal.html
nah, just use the classics... M2 .50
jmkasunich fully automatic, built in radar
I know... but too heavy even for a pimped up Hummer
belt fed vehicle mount 20mm?
and for even more fun, give it a water jacket so you can keep on it
yeah, and a semi following behind with ammo
I know the range, so I'm not too wooried about much of anything else on this puppy =)
jmkasunich: maybe a snowmobile trailer?
not for a 20mm phalanx
figure 3lbs per round, 3000rounds/min, that's 4.5 tons per minute
well, no, not for that, i'm talking a belt fed 20mm operated by me
holy shit, is that how much 20mm weighs?
guessing (complete round, not just projectile)
projectile is 20mm dia (3/4") by maybe 4" long, figure nearly solid steel... the math is left as an exercise for the student
hmmm, maybe I over-estimated
I get about a half-lb for the projectile
steels what, .28 lbs/cu in?
figure 1 to 1.5 lbs for complete round
[03:21:15] <Jymmm> http://www.militarystencils.com/images/Ammo/20mm.jpg
something like that, I used 0.3
yeah, that's gonna put some energy on target
4.5lbs / 18
f a soldier was carrying 18 rounds of 20mm the weight is 4 1/2 pounds.
only a 1/4 pound each... wow
what are they made of, aluminum? ;-)
20mm round will penetrate 1.62" of steel at 1 kilometer
I didn't realize you were talking about the OICW
those rounds are more like grenades than the 20mm I was thinking of
I wonder what kind of chamber pressure that round develops
jmkasunich I was just googling and that came up.
how bout a GAU-8?
20mm grenade vs 20mm rifle
jmkasunich: GAU-8, that's what an a-10 pilot sits on right?
my understanding is that thing can stall out the aircraft if the fun button is held down
projectile contains 0.66 lbs of DU plus an aluminum skin.... none of this wimpy 1/4lb complete round stuff
course if I was infantry and had to hump it around, I'd like the light stuff
[03:33:24] <Ircaddict> http://www.spiderweb.cc/dump/63%20Rounds%20of%20goodness.JPG
<-- my toy pales in comparison heh
nice toy nevertheless
Indeed it is, shot one before I went out on the boat this summer, and fell in love
got a good deal on it
I've been thinking about getting into target shooting
did some .22 target for a semester in college (20+ yrs ago)
I'd like to try a M1911 tho
1911s are classic
they are also like the small block 350 of guns
you can mod the hell out of them
gotta find a range somewhere nearby where I can try one out (rent for a day or something) and see if I like it
FINALLY! I figured out the pentagon... eeesh.
any ranges in cleveland?
haven't looked yet
so much to do so little time
(I wish I had some of the time I wasted when I was younger)
* jmkasunich googles ranges
looks like a few
"big bore specialties" ;-)
50ft indoor pistol range
less than 10 miles
but yeah, guns are definately a personal preference, no matter what anyone says
I can't shoot my friends SIG worth crap
they have rentals, $8 to $15
box of ammo, rent a gun, shoot for a day and see how I like it
although I only shot .22 for a semester in college, I shot arrows competitively for four years, did quite well... I wonder how well some of those skills transfer
I've never done any archery
I was a classic geek at a geek school... we were required to take two semesters of phys ed, and I didn't want to sweat, shower, etc... so I took archery and shooting ;-)
never expected to spend the next 4 years competing
jmkasunich too bad you couldn't work your scince classes into the shooting...
I thought I was gonna go into IT
then i got a car, and got more into engineering
I still do play around with Apache and PHP though
I did work classes into shooting.. I was an electrical engineer major, and I made a large digital clock to be used for timing at tournaments (you get 3 mins to shoot 3 arrows, IIRC)
nice thing about archery... the ammo is re-usable
well, brass is reusable
but you gotta take it home, reload, etc
I could shoot a whole tournament with 3 rounds ;-P
and a whole year with 12
what kind of shooting do you do? target, or just plinking stuff for fun? or?
I do target shooting. I'd like to get into IDPA.
I also like to go to the 80 and blast old car and computer parts :)
* Jymmm knows where to bury the bodies. Any more questions?
it's a local place we have
kind of like a large sand pit
ah, ideal for that kind of stuff
when I was a kid, my grandparents lived out on a farm... ground sloped down behind the house to a creek, then up steeply on the other side... same kind of thing
Brake rotors are fun to shoot up :)
One time (I must have been around 10) an uncle had several guns and we were shooting at cans, bottles, that kind of thing
I think he had a .22 and a .308
the .308 had a kick (at least to a 10 year old)
.308 has a bit of kick
alright, i have class at 9
time to hit the sack
lucky dog, I have work at 8
where you work?
Rockwell Automation (aka Allen-Bradley) I design motor drives
sometimes it is
sometimes its not (like when they blow up)
yeah, that would suck
I'm starting to wonder if I should have gone to Michigan Tech for mechanical engineering
I have a few ideas, I just don't have the knowledge to run solid numbers on them
jmkasunich : Hey, thats the fun of it! Especially when your wiring up a motor and the you connect up wire 6, which is really wire 8...
becasue teh marking rubbed off a bit
Jymmm: my drives are 1000HP, and 690VAC... when they blow up it is $10,000 or more down the drain
(and possibly new underwear)
and like 2 weeks to rewind the things i bet
It's AB, $10,008 is a drop in the bucket
( the $8 is for a new pair of shorts =)
they probably wouldn't pay for the shorts anyway
jmkasunich toss em in an inner-office envelope to the boss to sign the req. Bet he'll NEVER deny that claim ever agian.
but you're right - the real cost is time... engineers time, schedule slips, etc
yeah, burning up Bow thruster motors is nasty
I heard 2 weeks (or was it months?) to get those things rewound
usually when our stuff blows up the motors are fine, it's just the drive that goes
my motor and generator theory sucks right now
so i guess i'm not sure what you mean when you say the drive
the box that controls the motor
constant frequency constant voltage AC in (480V, 60Hz), variable frequency and voltage AC out to adjust the speed of the motor
[04:25:26] <jmkasunich> http://www.trane.com/commercial/upkeep/aftermarket/afd.asp
this is one of our products (we sell it to Trane)
the shiny headed guy inthe lower pic is my boss, the pic is at our first installation for that particular project
jmkasunich 1000HP... that's all?
i'm trying to remember, is there a seperate field generated for motors, or is that just generators?
(I was there too, but not in the pic - didn't want to break the camera)
depends... DC motors _and_ generators often have separate field windings
jmkasunich I'll remember that if we meet up sometime... my lenses are too expensive!
camera is too
well, all my parts are finished, time for bed
now i really need to sleep
nice talking to you
nice talking to you as well
Ircaddict you outta here too?
but i always leave my box running
so i just idle here
same here... G'Night Ircaddict
This is getting creepy.. I went to take a friend to the store and ended up coming back with a steel desk for the shop and another treadmill for parts..At 10 o'clock at night in a town where they roll up the sidewalks at 9....
that toshiba BMC is out for sale again
with fanuc 6MA control
L1000mm T600mm H800 mm table..
BMC? Bastardized Mouse Cannon?
I have no idea
and I have no idea about the size..
What do they want for it? Like i can actually afford anything.
60 place toolchanger
Oh boy, i'd only have to knock off about 100 7-11's..
I have a machine I crave for..
Better make that 150 with the shipping.
with my pay it'd take 12 years to buy one..-
and I could buy that bmc without feeling too broke..
It's 1x.6x.6 meter..
the external size?
Damn.. I'd give your left nut for that..
I dont know if I can fit it anywhere..
The wife is kind of fond of mine..
What is it? New/used/refurb?
The machine, noot the nut.
How old and how abused?
I dont know
I just found it on sale
Again, The machine, not the nut.
it's a old cheap machine
but I have no data..
That's frikken huge..
the mill I want is a 5 axis deckel maho ;)
* Phydbleep tries to remember where anonimasu is..
Decongestant induced short-term memory loss.
Crap.. Make that I'd have to knock over 300 7-11's (avg $30 ea) to get that and get it here.
I got to go
jus realized how little $30 is :)
Hehehe.. Ain't life a bitch?
are you in usa?
the used machines are cheaper there :)
Yeah, The knocking over a 7-11 bit is just to torture bill collectors.. :)
[08:44:07] <anonimasu> http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&category=12584&item=7510019072&rd=1
I could live with that
They call wanting money, I ask "What do you want me to do? Knock over a 7-11?" They say yes and I turn them in for incitement to commit a crime. :)
[08:44:45] <anonimasu> http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&category=12584&item=7508969744&rd=1
Damn.. I might have to bid on the fanuc.
It'd cost me 500 times the current bid to get it here..
the matsuura is what I'd want..
i'd have to cut a hole in the roof and set it in with a crane though.. :\
230V 50a 3-phase as well.. Oh Joy, I'd only need ~170 amps to feed the phase converter..
Morning. Mostly loggers and lurkers here now I think.
I had a nice conversation with Jymmm and jmkasunich last night
Things are most active evenings (USA time) and Sat and Sunday. Official "meetings" are Sundays
Alright, I gotta head to class for an hour, but I'll return
how's it going
windows uptime 7hrs 10mins 31secs
wtf was that?
guess is as good as mine
I see from the list that another has discovered that eme does not blend arcs
emc not eme heh
yep, I noticed that too.
Well soon to be fixed I hope...we'll do a final test/debug when paul gets here
* Ircaddict wishes he had the hardware to play around with
Stopping the screwy velocity calcs is about the only thing left to do (I think)
the cnc hardware irc?
That being said, my only machining experience is a class that I had to take as part of my schooling
but manufacturing is something thats always interested me
although I showed this to my friend, and he seems pretty excited since i guess he's looking to possibly convert his bridgeport into a 2 axis CNC setup
Ok I know what 1/4-20 is, but what's M8 x 1.25 ?
and from the way it seems, a large portion of the cost is in the controler
yes it typically is
8mm diameter, 1.25 TPmm?
Ircaddict Right, M8 == 8mm diameter, but the 1.25 is what?
thread per mm ?
1.25 turns per mm
* Ircaddict should go back to bed
damn metric system!
booting live cd :)
les: so are you a programmer by trade then?
I just bought every conceivable replacement drill bit in english but not metric
No irc I am an aerospace engineer
but I own a business
Ircaddict les started amyway and maryKey cosmetics!
les: Now that's bad ass :)
I dated a girl who's dad was an aerospace engineer
you don't happen to live in Brighton, Mi do you?
he I was close...Chivago
I do a mix of things in business down in georgia where I am now
About half engineering
the other half manufacturing
I try to keep it that way anyway
actually, one of the things i'd like to do is start a shop up here, do pure manufacturing stuff, and then eventually hire engineers and get into firearms manufacturing and engineering aftermarket parts for cars and bikes
pretty heavy into cnc machine design.
Did a lot of automotive stuff in the past...(and still some)
I have a few ideas in my head, but I don't have near enough knowledge to run solid numbers
No firearms...but I do some of that for a hobby
Well a lot of engineering is analysis...in fact most of it.
As in design first, and check numbers to see if it will work?
more like rough Idea...then check nombers...the design
A machine starts with basic goals
then lots of things like finite element analysis, bearing loads, dynamics, kinematics, cost
that's kind of where i'm at with this one idea, i have a rough idea, but I need to check the numbers (alot of it being shear stress) to see if it would be feasable
well shear stress is not too complicated
ok, I have TkEMC up
no, not really, but my physics teacher didn't really cover it :/
* Ircaddict digs for his physics book
Well it's not so much a Physics subject anyway
well, it was tossed in with the chapter talking about solids
talking about things such as youngs modulus, bulk modulus
in the simplest for it is just foce/area
without a machine connected, can I backplot a gcode program?
which is why you measure youngs modulus in pascals, or whatever other unit of pressure
andy_: with emc1 you can.
er, thats the way it seems anyway
yes irc pascals, psi, tec
just a momneet
mh lost my taskbar/startmenu kde
* Ircaddict wonders if there are any engineering for dummies type books out there
Ircaddict : "Engineering for dummies" == "an ar ch ist cook book"
cradek, the menu choices i have are EMC, and EMC Generic
what BDI did you install?
you should have the simulated machine then
no such file...
are there other .run files in /usr/local/emc?
(I don't use BDI)
I guess you should complain to your vendor (paul_c) about your nonstandard emc installation.
sorry I can't help.
ouch, ok, thanks
you could get and build the current emc1 from cvs.
I *think* you have a compile environment.
let me find the instructions, hang on
[14:24:32] <cradek> http://www.redpoint.org.uk/cgi-bin/emcinfo.pl?SimulatedMachine
these are the instructions I wrote a while back
your PLATs will be different
I'm not sure what your PLATs will be but maybe we can figure them out.
I'll give it a try later, thanks alot....lunch

* Jymmm sees crickets
anonimasu 11am here! Mornin =)
2:10 here :)
14:10 that is
anonimasu what time there?
hm it's evening anyway..
* anonimasu is drawing a fibreglass mold
I wonder how this will come out at the mill
hm is 22 minutes to mill a mold a long time?
anonimasu : I wouldn;t think so as long as you can get multiple pieces from a single mold
hm it's a single mold..
but well I've heard of 20 hour moldmaking..
with insane stepover
1% of tool stepover ;)
*tries to check how long it'll take
not too long
plus setup time
this is cutting at 1000mm/min
I need that kind of speed..
and a dremel as spindle..
dremel 30K rpm, but no balls. at least a trim router is 20K rpm and some balls
I am tempted to design a router for milling alu..
and let my mill be gecko powered..
and have the vital push it along..
I found 30krpm 1hp spindles from a company here..
the datrondynamics machines have 1/8 hp
the small ones
but 65k rpm
not the small ones..
40000rpm I think
but well I could buy a spindle like that and run a 1:2 reduction..
but well the bearings would cost more then the motor..
not stiff enough..
oil bearings if anything
axel grease bearings!!!
hm the mini raptor machines has 600w spindle
I want a machine that does 400ipm ;)
that's what the mini raptors do.
but well, faster would be "neat" ;)
too much loss of accuracy
speed being the inverse
hm, machine design counters that
you making this out of solid steel?
I am not making anything right now..
but if I am going to build one yeah..
alumimum or steel as frame..
and granite as table..
dual driven gantry with linear rails..
but that depends on how rigid you can get it..
alu probably woudlnt cut it..
I dont know how stiff they get if you bolt rails to it
would have to get somone to run some simulations on it..
or calc it
* Ircaddict installs BDI on VMware
still there anon?
read back a little
les: how far?
* anonimasu nods
I think I am going to rescrape one of the vertical mills
anyway...steel rails on aluminum support is not the best
it is a bimetel strip
martin...are you coming to code fest?
les: do you come to fest ??
Well fest is kind of coming to me
at least part of it
We will test perhaps some changes done on my high speed machine
should I take a spindel with me ?
I'm also planning such a high speed machine
you ought to consider coming down with Paul and staying a bit
it'll be trouble building it if it is steel.
but I guess it cant be helpes..
I can mill steel but I dont enjoy it
steel is easy to cut and weld
same specific stiffness as aluminum
les: what's a good material then?
epu-crete is out of question..
or somthing similiar due to the trouble getting it over here
and very very expensive probably
les: got a better idea?
ordinary structural steel is good
anonimasu See, les agrees!
* anonimasu slaps Jymmm
I'd rather have it in somthing like that..
anonimasu you wuss! Straight up with lime & salt!
anonimasu : Though, Cadillac Margarita is the exception.
les: moving gantry..
wow... an hour just blew by :/
A-L-P-H-A : Isn't it amazing!!! An hour blows by... even hour on the hours, 24 hours a day, 265 days a year, fot the last... oh say.. BILLION YEARS! =)
* Phydbleep sends A-L-P-H-A a speeding ticket for moving 1000 MPH with the planetary rotation..
Phydbleep I thought it was 17K MPH ?
You two are messed up.
A-L-P-H-A : Eh, you love it!
24K mile dia, 24 hour rotation.
17k is orbital velocity
dia != circumfrence
8K mile dia, 24 hour rotation.
Oops.. I forgot to add systemic and galactic motion to that... Your'e nicked laddie.. :)
wait, so which is it?
24k or 8k dia ;)
"it's a fair cop, but the galaxy is to blame."
8K dia, 24k circumference.
* Ircaddict checks
3900 and change miles for the radius at the equator
* Jymmm thumps Phydbleep with a light year! See what you started!!!
Ircaddict: Now, Look up the size/mass of Phobos (moon of Mars) and it's orbital period.. Then tell me what's wrong with it. :)
uhh, can I get a 50/50 lifeline with that one?
phobos is a captured asteroid I think
The projected mass doesn't match with the size or orbit.. Phobos is too light for it's size..
or mars does not have a mettallic core...
what did they base it's density on?
I'd love a close-up hands-on look at it. :)
Spectral response of the surface to get a material.
ahh, but it's not gonna give what's under it ;)
and unless god is playing some dirty tricks on us, it's kinda hard to break the laws of physics
Surface readings say it's rock, but the mass is too low for it to be a solid chunk..
It's a hollow Easter Egg... alright!
Not a clew.. But I's love a look inside. :)
* Ircaddict turns his chair and plays the keyboard a bit
* Jymmm hears dogs howling!!!!!!!!!!!!!!!!!!!!1
I got bored today a bit...have the scope hooked up to the microphone to diagnose some rfi in the audio
* Phydbleep Screams "BANZAI!" and attacks the postscript encoder tachometer file with 'vi'.
so I started humming trying to make a perfect square wave on the scope
now try humming to mimic white noise
humming? I would have thought tapping to get a sq wave
no a square wave train...not a heaviside function
I also have been known to talk backwards...record it...reverse the recording so it comes out forward
now that is hard.
les Not really... we all do that to understand you every day =)
Humming should get you a sine-wave.
les most of the stuff that comes out of your mouth is greek =)
PHY...I got a fair square wave with a certain tone
Or Martian. :)
oooo sounds are sine waves
cq cq cq dx
yeah 1000 miles with 1 watt?
* Phydbleep hangs laundry on Jymmm's antenna..
les LA to Sydney on 7 watts
cw or voice?
* Jymmm watches Phydbleep laundry fturn into carbon dust
les HF SSB phone
I think the record is comms with voyager
voice == phone (ham)
it's an fcc thing
les A friend loves goin lower power and making QSO's
I have no fcc liscenses
used to for aircraft vhf
but they abolished that
i don' need no stinking license :)
now anyone can key up on a handheld aircraft band radio and shut down major airports
* Jymmm does
the license thing
not the shutdown airport thing
* Phydbleep prefers Spark-Gap transmitters..
Let EVERYBODY hear it on everything. :)
I guess my dad used to run around with his CB radio going to a linear amp as a kid
on a nice summer day good for flying vhf aircraft band is a whine of hetrodynes
whines and squeals anyway
les: what rating you got?
PPASEL with complex and high performance endorsement
aircraft single engine land
Until I get money to start, I'm stuck flying in X-plane for the time being
x plane is good
hell yeah it is
pretty good flight model...about like the real thing
holy hell, x-plane 8 is ported to linux?
appearantly we're (Canada) maybe having a new election again.
harder because you can't see as well
horray for monority governments.
haha let's be nice to our northern neighbors
we have the moronity gvt I think
les: both me and my friend (who has is PPL) both think the flight model of x-plane > MSFS
what ever that means...haha...I find it pretty real
* Phydbleep is starting a church, "The First Church of Bureaucratic Incompetence.".. If you have faith that an incompetent bureaucrat mess up your life you can join right now. :)
les... you the math guy right??
Faith? I have 30,000 hours of video!
I do math some yeah heh
c'est moi Phydbleep
les oh go factor Pi will ya!
i need some help with terminal Velocity calcs
* Phydbleep thinks Jymmm has a subscription to C-Span.
more aerodynamics than just math but hey...I do that too
if i drop something it falls accelerating 32 ft/s/s..right
cool i knew i rememberd you from somewhere
so after 1 second it has fallen 16 feet
of course this is neglecting wind resistance :)
ok hypothesis... torpedo shaped permanent magnet falling thru a tube of copper coils
les: If a chicken and a half, can lay an egg and a half, in a day and a half.. How many times will a British MP bounce when fired from a circus cannon?
dmess is designing mass drivers here chris
les: Or a "shake it up" flashlight.
whichever way you wanna go
i need to get a trace of speed Vs Pos'n and the # of coils HIT ( for lack of a better word....
but go ahead dmess...a magnet in a tube of coils
* Ircaddict is confused
dmess: There'sa lot of variables to that.
Ph... yeah... but i got a gated push pull system that may give us perpetual E
are we talking a charged coils?
Are the coils driving or driven?
perpetual energy...uh oh...lost me there
rate of change of magnetic flut is what were after here to design a multi layered coil tube of max eff. for the length we have to fall...
simple principles add up to the answer...
dmess: That will depend on the strength of the magnets as well.
what are we looking at for a magnetic field strength?
lotsa hoopla to the mags i wanna use... proto on P/mags to prove design intent
i can get .25 T
k, and whats the radius of the coils?
full or proto scale..
full... 4' and magnets of 2T
you plan to construct this out of...?
dmess: Are you playing in a mine shaft or what?
sure... Macassa #3 shaft ... gold mine in Kirkland lake i helped sink to bottom in the 80's
we DONT fuck around when we have a good idea...
energy you can get from that is m*g*h
dmess: Well, get oout of there, It's mine.. See say's it right there -> Mine, Mine, Mine.. :)
7380' plumb within 3/4"
what is the mass of the magnet
dmess: Is there a mate to that shaft with a connecting cross-shaft?
3 compartment shaft
mass is a function of length...
well give me a number
mass is a function of density and volume
100 mm neodynium hockey puck will be heavy..
i figure it'll need about 4500 KM of 1mm dia wire to do 1 tube..
dont think hockey puck... think 40" dia. x 12 ft.
les you want a number? Try 104723
Is she good?
with 100 pound weight differential to the other side
les She's Prime!
1m x 4m ?? That's not a torpedo, that's a tank-trap.
at the top you add 1/2 that M .. and lose the same 1/2 that M at the bottom... effectively reversing its direction
Oooh.. N35 to N38 might give some really wierd effects at that scale..
I must bow out of the conversation at this juncture
since I have no bloody clue what the hell is going on
this device has the E to take care of them all....
to put things into perspective let's have a thought experiment...let's say you drill a perfectly straight tunnel from one point on the earth to the other....
dmess: Don't eat spinach or liver while you're working on that..
les : Ok, done. Now what?
ok.. 1000 Kg magnet falls thru athe hole
so the tunnel might be from one side of the street to the other...or to china through the center of the earth
dmess Can't, it's filled with salty water
after it been lined wit the coil
let's also say that we can drop a weight through the hole in a manner that it does not hit the sides (maglev?)
You should break that up into shorter coils that are 70% of the magnet lenght.
you just used an outside source
no more perpetual E!
it acc... and falls... moving inducing a current in the coils.. fed to a diode pack and then a battery or similar
well it's gonna make DC
How long would it take to fall through the hole to across the street as opposed to the hole to china?
so why the need for a diode pack?
but... remember...2 holes and the bullwheel..
(trick question of course)
dmess: Lot's of stacked coils and diodes.
on the up the dc reverses polarity
les... work with me dude...
dmess: And you've just used 101% of the energy from the fall for the return.
no... cuz there is equal + differential fallin on the other side...
youve used the differential to generat 2X te potential...
dmess: Then it's balanced and you need to add energy to make either move?
dmess I'm terribly sorry but I am going to have to pull you over for attenpting to violate the first and second laws of thermodynamics. Put your hands behind you...and watch you head when you get in the patrol car.
in order for the fall to start there has to be a differerntial firs..
les: He's not trying to violate them.. He just wants to get to second base. :)
yes i am gating "mass" in at the top and out at the bottom
?? what do you want to do?
sounds like "Gravitic shielding"
* Jymmm revolks Phydbleep's Trekkie Membership
shield B while A falls, shield A while B falls, rinse, repeat..
if the Gravity shield... scenario holds.. great... but it means with 1g differential... it'll make X Kwatts on every pull
watts are a rate
do you mean joules?
sorry brain fart
but we'll get them too
its all Energy right
dmess: Have you thought of doing the same basic thing using low-pressure geo-thermal steam to drive the pistons back to the top?
dmess so is me eating beans =)
Jymmm: Yes, But no one has fled in terror from dmess's energy source yet. :)
Phydbleep : Hey, If I can clear a room in 2.3 seconds with just beans....
geo that deep isnt really that high... at 7800' down it was HOT to work... 130 F and 90% humidity... but cap it and its a sponge thats been mined for the last 100 yrs...
i wanna build a small perm magnet model .. to prove concept.. even if i only get milli volts
dmess model of what (I really haven't been keeping up)
get a pillow J
I'll take "What the hell is going on here" for 500, Alex.
dmess: Go get one of the "shake-it" flashlights and dissect it?
dmess tried, couldn't sleep
Phydbleep I have one of those
energy system im trying to get the math to fill in with the model
dmess: I've got the #'s here somewhere.. I'm working on a geothermal generator system for some hippies. :)
Phydbleep... ive done so.. its a linear generator... i need/want 36" drop on the model..
They have live steam on their property. :)
bonus bucks... where?
i'll go drill it ...open hole drilling
dmess: 1. dont use metal pipe. (eddy currents) 2. chuck a piece of pvc in a lathe and wind coils on it. :)
dmess: Jemez mtns in New Mexico.
i was gonna use cardboard...
PH i wanna visit .. ;)
Line it with 1 mil tellon film then.
teflon == toxic
once the coil is wrapped i wanna laquer and pull card tube
Cardboard is rough as hell and the eddy currents from the coils are going to throw the magnet into the tube walls.
Or use a piece of acrylic tubing.
not if the mag is guided by a length to dia. of say 6 to 1
glass wor any good??
dmess: It's still try to rattle.
ok well imagine the same bullwheel at the bottob with a similar ines hooked to the BOTTOMs of the torpedos...
Your coil section length needs to be 70-90% of the magnet length for best effect. Stack more coils on the tube for longer pieces.
constant tension... no rattle..
so NOT 1 continuous coil.. but sections..
Yeah, 70-90% of the magnet length.
how about quadrant sector coils??? 4 to a dia??
1"dia 6" L magnet should have 4-5 coils on a 36" tube.
you know this flashlight has a one farad cap in it, right?
so were talkin' .25 dia wire or so??
i figured the diode pack would need a cap in there somewhere..
WEll, were talking 1 F for a single LED
Jmmm i understand
dmess ok, carry on =)
dmess: .25 dia magnet or wire?
am i just out to lunch.. cuz this ALL works in mines melon
* Phydbleep saw wire, but..
remember..its a mile and a half to bottom
That's power generation. There'll be anothere 20 or so at the bottom for braking..
unless you want that magnet to drill the hole deeper.
so why 700 coils???
12ft magnet.. 7200+ ft hole.. 700 10ft coils for power, 40 5 ft coils for brake.
Did I miss anything?
braking is done when the top begins to get MASS gated into it... and the lower one gets mass gated out of it
dmess: Leave the 40 5's in there.. Youll want a safety in case the cables break.
coils are feedback devices only NOT input devices
cables break... 200' of anti gravity... might have a chance ehh...
dmess: Leave the 40 5's at the bottom wired for braking at ALL times... Set them below the others.
right.. what i was just mentioning to my wife..
bellow thje loading pocket
7800 ft? 750 coils / 100ft dead space / 40 5" brake coils.
7500 ft? 710 coils / 100ft dead space top and bottom / 40 5" brake coils.
if i can show justification that we can make more E out of there than the haul gold now... they' GIVE it to me to try it out...
dmess: Wait till they're at 12k ft and use 2 tubes? pump water down and use thermal exchange units?
Hell, You could probably heat a town with the waste heat that's there now.
dmess : This flashlight also has a hole in it to exhaust air
pressure from the magnet itself
that hole is bottomed out its a skipping shaf right now.. it was never a GOLD hole.. was put there to elliminate 2 trams to the Winzie hoists
and I dont know why... but when the magnet leaves the coil, there's a sizable gap
Use a tubular magnet.. You're only really worried about the flux density at the interface area for the coil/magnet interactions.
and how do you know that ...you modelling it as we speak???
| |coil| <mag>|
add an inner core too??? ; )
the gap is about 1/4th the length of the magnet
dmess: Modeled it a month ago for the geo-gen.. Trying to get the amount of NFeB down. :)
section of the mag you mean.. right
dmess: No inner coil.. The hole is for air pressure equalisation.
dmess (talking out my ass here) But I think it has todo with the magnetic flex... letting it collapse compeltely as the magnet is at the end of it's travel
Yeah, You have to get the coill 99% out of the field, Thats why I said short coils.
end of travel.. or end of individual CIOLS
coil length == magnet length (too)
Coil WINDING length == magnet length.. The coil former will make it longer.
what Phydbleep said
Phydbleep STFU if you dont know what I'm talking about =)
im seeing... after repeat beats to the head
Phydbleep Casue I sure in the hell dont' know what I'm syaing =)
And at the velocity that thing will 'see' about 70-90% of the magnet.
s/at the/at that
Hey.... how about a coiled tube ???
the is fine..
what you think were talking about
dmess NFC =)
dmess: Might be more power to just stick a Saturn-V engine down there and use the tube for a MHD unit. :)
give another meaning to FIRE inTHE HOLE
dmess you have geo steam to bring the magnet back up ?
no... differential mass to bring the mass back up
dmess: Way better than the way that requires pennicillin. :)
dmess: I still dont see how you're going to get the mass differential..
who own a balance scale??
* Phydbleep has a ruler, a tack and some string.
how about reciculating ball bearing magnets =)
add mass to one side AS you remove mass from the other.... do the pans NOT accelerate???
isn't that pertetual motion?
yes... and then... perpetual E.. but im NOt moving the same mass...
some in LOTS out..
Yes, but then you have a light side and a heavy side and might as well put a cast iron paddlewheel in the skip shaft and let the infill turn it.
acceleration is calculated using Differential NOT mass and over 7000' it brings much E
I'm assuming that this shaft is getting infilled with debris.
dmess how much E do you think is gonna be needed to bring that magnet(s) back up again?
you'll be fighting gravity then
both the up and down actions bring energy... sinsc they are both moving magnets thru a coil system
dmess two differnt coils you mean?
I'd suspect if you put two moving magnets near the same coil, they'll cancel each other out
dmess Got Water out there?
2 different coils... one at the top of the cycle... over a pullu to bottom... attatched to same masse and magnet... except for a positive/vegative differential valve...
dmess how far are you from tthe coast?
the mine shaft
2 different isolated coils..
coast of what... ontario in land locked
is that where the mine shaft is?
yes... Kirkland lake ontario Canada Planet earth...
3rd little one from the sun
dmess : Ok, well what I was thinking is make the magnets bouant in water... and left them float to the top.
kinda like those tubes at the banks.
can we take this up in a feww i gotta dropp off the wife
kickin her to the curb huh?
Not down the shaft I hope. :)
cant... sendin her to work.. on our anniversary.. even.. 15 yrs..
"Honey, could you look done this hole for me?"
dmess Happy Anniversary
thx... come lick the scars if you mean it ; )
* Jymmm kicks the scars!
brb... im gettin looks...
those are "puppy love" eyes! ROTF
You mean like the way the puppy 'loved' my shoes to pieces?
dmess: MSG for Mrs. dmess, We're only joking. Please do not do rude things to him with a melon-baller. :)
im back.. she didnt scold me... too much...
Did she scold you too little?
not nearly enuf... ; (
15 yrs ago today i was gettin in alotta shite
Now it's "You blew up the garage? That's nice dear" ???
wedding was at 11:30... we were well OFF by this time... ; )
* Phydbleep would not complain.. It would give me an excuse to build a garage in the first place.
ive wrecked 9 vehicles since then... shes gotten alot of ... "im comin' home on the hook tales."
* Phydbleep only brings them home on the hook when he buys a beater..
i dont fix em any more... detroit makes lots of em...
I won't buy most of what they're making now.
i drive beaters away... and bring em home on the hook.... to clear my shitou outta them...
500$ for a propane powered suburban.... drove her for 200 000 Km
* Phydbleep does not trust cars with a Ca $0.10 deposit notice embossed over the windshield.
gas suburban from a police auction 1500$... 2 yrs and i learned how to do tranny's on that one...
$0.05 in OR and WA. :)
no deposit... solid vehicles... just got to steal them without the mask on..
And the "Please Recycle" across the trunklid is just wrong..
Oh..I was talking about the new cars. :)
i recycle them.... i also do my own crash testing though
I just lost an assload of data
and when i send them away... trust me its DONE
and this is what data recovery is gonna cost..
* Economy 5-7 Business Day Service: $500-2700.
There is a $200.00 attempt fee if the data is not recoverable.
* Priority Round-the-Clock/Weekend Service: $1800-8900, with a $800.00 attempt fee.

I buy beaters for <$250 if they'll drive home and <$50 if I have to tow them in..
you work on them too.. dont ya
Irc... bites to be YOU
Not really.. 90% of the population is just dumbasses.. :)
$35 VW, Blown fuse.. $75 Ford F250 4x4, Plugged fuel line.. Etc, etc..
i heard it said that 10% of the population has 90% of the wealth and 1 % has 90% of the knowledge
no rich know it alls out there
we're all broke
Of that 1%, 90% are in it for the money and the rest of us could care less. :)
nice grab on the 4 x 4 ...too bad its a ford
ever seen a UNIMOG
I never even touched the Ford.. I traded it for a a 73 Audi LS100. :)
ahhh theres a car..
dmess: Yeah, Unimog.. the bastard child of a Tonka-Toy and a Mercedes. :)
There's several mog's in town.. The redneck love them for hunting buggies.
DAD had one for me to play with as a little child... i ran it in/out from the muckin' station at -550' AGL
And then there's the guy who has one just to annoy Hummer-yuppies.
i was 7 yrs old at the tim
KOOL... i seen one near here has a car wrap saya hummer EXTRACTOR
