punk84: If you're worried about the 5V line you can use a LM7805 with a heatsink tied across the 12V to get 5V.
LM7805 = 5V voltage regulator.
Dunno about the limit switch issue though..
* Phydbleep is still building a machine.
if your 5v is high, so is the 5v running your parallel port - there will be no problem feeding it into the port.
it's also possible that your measurement is wrong if you have a cheap meter.
Too True. :)
or cheap power supply
* Phydbleep has lots of cheap meters and averages between several. :)
cheap ps :)
* Jymmm hugs his Fluke 77
Check the hardware monitor in the bios and it will tell you what the mb thinks the +5V line is at. :)
true, did not think of that
oh, like that's accurate =)
really none of this matters - just use it, whatever it is
what cradek said
* Phydbleep tries 'man -K volt'
k i will
punk84 : [16:04:34] <Jymmm> 5.2V itself will be fine.... =)
Jymmm: nobody trusts what you say if you pervert your punctuation into smileyfaces.
Jymmm: No punctuating your perversions either.. :)
look out, it's an epidemic!
* cradek washes his hands obsessively
BTW.. For those that asked about the character.. þ = Unicode 00fe
punk84: I don't know if it's part of the distro you have, but 'gkrellm' on FC3 has a voltage monitor.
missed me people? :)
A-L-P-H-A: Yeah, The targeting software needs a lot of work. :)
We hit the neighbors dog and took out a window at 7-11, but we missed you. :)
sounds like fun
Beer does not aid in target aquisition..

looks, like I'm gonna need a highspeed spindle anyways now, to do engraving.
for this damn product.
BBL.. Off to the store for food.
A-L-P-H-A: Isn't that the way it always works? "OK.. Now I need X to do Y.. "
well, I had X to do Y. But this new thing needs X do to Z.
or W to do Z.
as X isn't required.
[02:39:57] <Jymmm> http://www.gotmilk.com/news/news_040.html
Woohoo! I knew I saved this hunk of junque for a reason!
* Phydbleep is looking at a surplus Endevco accelerometer
Accelerometer + encoder + geared up drive motor == High speed balancer. :)
Sure beats the hell out of a 1972 set of 1300cc VW ignition points for a sensor. :)
Just so "I" dont forget. :)
Phydbleep, why the hell do you need a balancer anyway
fenn: Because I want to build a few things that will rotate at high velocity?
yes, of course, but what?
Gas turbine parts, impellers, Parts for a couple of projects and an experiment or two..
cool that's what I was hoping... i'm planning on building some gas turbines too
* Phydbleep is hoping to balance at 50K RPM to run at 50-70K RPM.
Hehehe.. 3/4 HP, 1725 rpm motor with a ~26:1 gearup ought to deliver ~50K
Yeah, I'll make a step pulley so I can walk the speed up as I get it balanced.
I'll start at 1:1, then 5:1, 10:1, etc..
tesla had a special turbine case that allowed for grinding on the turbine while applying air to spin it up.. automatically balances the turbine at that rpm
Yeah, I've seen that.. It only works with the bladeless disks though.
how does one balance a bladed turbine?
i mean, where do you remove metal from?
Well... if you started out right and balanced the disk, then weighed/matched the blades all you should have to do is a little filing on the edge of the disg or if you want a siren drill a hole. :)
The Tesla balanccer will bend the bldes if you try it with a bladed disk..
i was under the impression that a lot of turbines were one piece cast construction
Depends on the turbine.. Some are one-piece, some are assembled from disks/buckets.
The spot welded blades are a bit scarey looking. :)
hmm only multi part turbines i've seen were held together with centrifugal force
These are little ones for models/hobby stuff.
I'm moe interested in the Tesla designs myself.
yeah me too
maybe that's because of the wild claims surrounding it
but also because it's more resistant to temp. cycling
* Phydbleep is going to use heavy stainless for all the moving bits to eliminate warpage and to provide a decent scatter-shield..
for a tesla turbine or bladed turbine?
I've got an 11x60 lathe.. I can make a hell of a stack. :)
have you seen the patent in the 1980's about increasing cross sectional area between discs as you near the center?
I htink so.. I remember something about a patent that took advantage of the gas expansion in a Tesla system.
i'm trying to think of ways to do that without making it either 1) too piggy or 2) explode from centrifugal stress
so much gyroscopic force that the bearings fail
sluggish responding to the throttle?
sluggish isn't so much of an issue depending on the application
Ahh... No throttle on this one... Full Scream Baby! :)
i'm planning on starting with teeny tiny motors ala steve redmond
~6" here for the first ones. :)
how long have you been wanting to make one?
0.045 stainless for the disks and 1/2" wall pipe for the sctter-shield.
i've been scheming since at least '99
I think.. It was quite a while ago.
i wanted to put an allison 250 in my honda civic and started to do research on turboshaft engines
I was working for a OMC dealer at the time and liked the new Wankel they were pushing but thought it was too much mass moving in the wrong directions. :)
heh a wankel isn't a rotary engine it's just a triangular piston engine
maybe a six-trochoid wankel would be balanced :)
* Phydbleep does not want to see a piston doing figure 8's inside the crankcase..
Or a Spirograph imitation.. :)
it's really pretty sad that there's not even one commercial turbine powered car
Hehehe... There's a nut-bar here in town that sticks jets in everything. :)
my kind of wingnut
where does he get them?
i went all over the southwest looking for small turbinee engines.. no luck
[10:50:48] <Phydbleep> http://www.unitednuclear.com/jetplans.htm
[10:51:19] <Phydbleep> http://www.unitednuclear.com/jetcars.htm
There's the right page. :)
somehow i find that hard to swallow
I love the "STAY CLEAR" license plate frame right under the exhaust on the CRX..
damn! he beat me to it by
i give up
He had a pulsejet on a Schwinn too. :)
rofl.. 0-300 in 4.9 seconds
I think this is the same Bob Lazar that claims to have worked on UFO crap at Area-51.
I do know there's some really WIERD SH*T goes on out in the desert south of town (toward White Sands) at night sometimes..
how could i have missed this website?
Hehehe.. And the BIG laser power supply over at Sandia labs gives off some really strange effects in a thunderstorm..
* Phydbleep has seen sodium vapor streetlights add just enough energy to make the atmosphere lase in the ultraviolet on that side of town...
i'm not really up on my laser theory
They only did that once.. Too many complaints from people who were seeing purple spots..
3 days later.. :)
The nitrogen in the air was ionized to just below the kickover point.. The UV from the sodium lamps added enough energy to make it superradiant.
They learned to shut down the big power supply when a thunderstorm was coming in after that.
Sorry.. Not sodium lamp.. Mercury vapor.. They've been swapping the Hg's out for the last few years.
i found some mercury vapor lamps in the dumpster today
need to read up on how they work
Woohoo! Suntan, skin cancer and retinal damage. :)
funny thing is, that was at the grocery store dumpster
hey man plants love UV
kills the mold that attacks the bottom of the stem in seedlings
New laws are that Hg's are going to be verboten here due to light pollution..
in NM or the whole USA?
I had to show the neighbors the fluorescent bulb from my yard light to keep them from reporting me to the city..
gee he's selling mass-spec tested samples from the trinity site for $40 and claims that they are expensive
Albuquerque for sure.. Not sure about out in the boonies..
you could buy a 108 LED UV lamp from unitednuclear and put it up there to piss them off
i can't even imagine a possible use for that thing
Scorpion hunting. :)
They glow real nice with a good UV source.
wow i think i could spend a lot of money at this website
You could also give someone a suntan.. Though a wall or two. :)
LED's arent high enough energy photons to burn you
I wouldn't want to bet on that.. 108 of the 390nm's is a lot of UV..
Hehehe... one of those and a cylinder of the uv flourescent acrylic for a hell of a fake laser show
I'm annoyed at their phosphoescent powder though.. It didn't survive a trip through a cone-6 kiln as a glaze ingredient. :\
gee i wonder why
They assured me it would.. "Oh, Sure.. Just keep it under 2500F and it'll be fine".. NOT..
was it electric or gas fired kiln? cause reducing atmosphere can do weird things sometimes
Tried both.. No go.. :\
can you mix it with powdered soda glass?
Even tried running one through the soda kiln.. Same lack of glow afterwards.
epoxy it is then
Nope.. Just no glowing ceramic glazes.
Hmm... 05:30.. Time to rewire the "snooze" button for "self-destruct" so I can get some sleep...
just snort some m-state powder and you won't have to sleep
I'd rather have sex with a tree chipper..
* Phydbleep does not play with powders.
* Phydbleep is the kind of sick puppy who leaves a line of Ajax on the edge of the sink..
yeah but m-state is superconducting. it quantum tunnels through your skin
Do that in a bar and wait for the screams of pain.
do what, have sex with a tree chipper? :)
No.. The Ajax on the sink..
Worry if you hear screams then "Smmooooth!.."
* fenn raises his eyebrow.
People will snort all kind of funny powders laying on the edge of the sink in a neat line. :)
Even if they have "no clucking foo" aboout what they are/where they came from..
50% of this town is burnouts and the rest of us are having too much fun playing practical jokes on them to develop a drug habit. :)
sounds like a fun place to spend your winters
Beats sitting on the street corner with a stack of score-cards waiting for a wreck. :)
Ehh.. You get a 3.2 for the collision, but a 9.5 for screaming at the cop. :)
what's a perfect 10?
Rear-ending the cop. :)
Seen a couple of those here too.
My favorite practical joke on motorheads is catch one at a light who doesn't notice the cop pull in behind him, floor it when the light goes green and hit the cruise control at 30. :)
Doen't matter who it is 99% of the time they floor it too and keep it there till the cop lights them up. :)
If you really need an unbelievably powerful magnet, here it is.
Uses include magnetic steering of nuclear particles in homemade accelerators, magnetic beam amplifiers, etc.

Prius is now known as TurkiyeLee
first cut at publishing this site
have a look?
you have paul_c there yet?
les, sure ... fire away
not yet...early next week
* robin_sz nods
[17:53:58] <les> http://www.broderickcrawfordart.com/index.html
I could not use oscommerce...ipowerweb has some problems and are working on it
have not set up the store yet anyway
robin: does this make any sense to you?
a pal of mine uses a network connection
static IP (real)
but the GW is in a different subclass
works on doze, doesn't on linux
that doesn make any sense whatsoever
define "differetn subnet"
see.. byt "different subnet" it generally means you have to go through the default gw to get to it ...
which if the default gw is on the different subnet would be err, unreachable
Network Destination Netmask Gateway Interface Metric
0.0.0.0 0.0.0.0 220.127.116.11 18.104.22.168 20
10.0.0.0 255.255.255.0 10.0.0.101 80
I suspect the gw is actually on the same lan segment right?
I don't know ;)
but I found it very odd.. to say the least
22.214.171.124 is his local IP on his ADSL I guess
but his local ip, right
the second one is also very odd
10.x.x.x should be class A
can be used as C
you dont have to use an A class
so .. it the first one,
in linux it won't let you add that route
dotn blame it
route add default gw 126.96.36.199 dev eth1
(or wherever his 188.8.131.52 is bound to)
says it's on a different SUBNET
thats also true .. but a different subnet to what?
can't remember the exact words, but that's what it says
to the local ip/netmask
seriusly fucked up routing
so it's not reacheable
that what id have thought
les: about doesn't work
oh it's just a first cut
thats what you need a gw for .. to get from this subnet to that subnet .. and if the gw is not on the subnet, you am fuxxored
lots do not work yet
have not put in the links
les: anyway, looks arty :)
that shadow effect is from photofiltre....pretty neat for a free program
les: comments? the black text in the purple boxes need to be the same height and weight and anti-aliased, looks a bit rough at the moment
yeah I know
and dont do your floating trext images like you have
rather than using the background as a , err, background
use text over transparent
anti-alias the text edges with a vaguely similar colour to the background
well the backgroungd is tiled
yeah, I know
which page is that on?
ick and dont ever do font size in pixels :)
looks ok from here. What's the problem you see?
fonts in pixels?
its text over a background ...
thats generally not how its done
oh sitespinner did that
why not a fully transparent background?
is there a better way?
imagine you want to change the bg image .. even just its tone or hue
you cant without remaking all the images for the text right?
ah...can't seem to make the background transparent in sitespinner
would have to write code
if you do the text images as text over transoparent, you can use different bg in a snap, or if the bg image doesnt load, the site still looks OK
what browser are you using?
remember, many people with bad eysight will turn off bg images anyway
must look different in mozilla
oh, and the link images have no alt text
seems pretty smooth in ie
yup alt text is on my list!
finally, fonts sized in pixels is deeply bad
ok if you say so
one of the worst useability sins going
again it was just what sitespinner did
remember they will appear the same number of pixels in a 640x480 and a 1600x1200 display
robin: wanna hear some more?
It's one of those things where I must give them a VERY easy to use software so they can manage it themselves
plus, it prevents people with impaired vision from varying the size with their mouse wheel
but it may compile poor code
well, you asked for my comments :)
let me check if I have options with that
finally, run it through validator.w3.org :)
robin: imagine that that gw is actually the providers primary ns
ok only does pixels
"best viewed with 1024x768" heh
there still might be an option somewhere though
well, thats a shame, it will upset anyone with imparied wision who is used to using ctrl-scroll to change text sizes
only had the program 1 day
seems to produce valid html, thats a rarity these days
I will ask about that on their support group
I should imagine that a number of the potential clients are in the "silver surfer" category
it's an art page, I doubt the target audiance is someone vision impared
anyway, fonts in pixels is just such a bad bad bad thing,
yes it will look screwy in anything other than 1024 768
im in 1600x1200 here
that's what alt tags are for
les that would be my only bitch... fixed resolution
Jymmm: strangely, text doesnt have alt tags and its text that is set by the font sizes
ah, and the big drop off
robin_sz I thought you were talking about the gephic text.
once you click on a page, its a dead end
Jymmm: nope, thats set in images, not fonts
Oh fixed font sizes
yes, in pixels
looking at source now.... UG-LEE (css wise)
I hacked the css a bit
that is only for the gallery stuff
85000 div id tags
yeah, weird that it defiens soem style elements, then expllisitly uses styles in the layout
thats OK, thats justthe way things are
I had a gallery software batch process the images....but did not use the pages it created
just the thumbnail and big images
anyway, navigation needs to be consistent
no dead ends
yeah I have not put links back on most of the pages yet
oh and "Select one of the three artwork categories below" is not centred under categories
just a first cut
by quite a way
Love the border = 0
let me look
well, you asked for comments :)
artwise it looks nice
oops I didn't center that heh
too many div id= tags though
well the festival is tommorrow
wanted something up
will fix it later
les dont let robin_sz's microscope scare you away =)
this whole thing is about 4 hours in working on it so far
artwise it looks nice
the background and the drop shadows work nicely for me
well, I need to hire a kid to do this.
I shouldn't be heh
well it's just for my uncle
and I only charged him a kilobuck.
les Be sure to put navigation on EVERY page, in case someone come sto the site from a link.
but family always deserve the best right?
I was having fun on the laser today
with high pressure nitrogen
Hey I'm an engineer...for a kilobuck I can only work on this for 10 hrs!
Well thanks for the comments. I have to go to town and set some festival stuff up.
its actually quite nice
but well you asked ;)
well it's perfect except for the bad bits.
well .. mostly
so .. having taken les' html skills apart ...
time to continue taunting Jymm about ERP and antennae
robin_sz 100 watt radio + antenna =< 100 watt
100 watt ERP?
tha't NOT what I said
what did you say?
exactly that three lines up
well, it doesnt mean anything
it does.. kinda
100 watt radio = 100 watts pTot
100 watt transmiter
100 watts radio + 3db antennae = 200watts ERP
+ antenna ->under 100 watt (because of losses)
but no one cares about output power
and many bands (most even?) are erp limited
they care about ERP (or EIRP)
and its erp that counts for signal stregth
and its erp that limits the output of wifi cards
you can have 50 mW (common on wifi)
and the limit is at 100mW
actually .. it can be more
up to 1w
Ok, wifi is the ONLY restriction I've ever seen that has an antenna restriction.
not in 2.4
Ok, wifi is the ONLY time I've ever seen that has an antenna restriction per the FCC Rules
you never read your ham regs then
2.4 limit is 20 dB
even arecibo has an ERP limit
it's some MW's
robin_sz it's an unlicensed band
no such thing
like i said
no such thing
unlicensed .. hah
it is very licensed ...
there are some bands you don't need to buy a licence
but.. licence exists
you cant run a MW on 27mhz under the terms of the licence
even wifi is licensed
robin_sz quit being a pita... you know what I mean!
in that so long as it complies with t apec, you dont have to buy one
well, you were the one that told me I knew jack shit about comms
and you dont even knwo what erp is
it's eirp afaik
robin_sz No, I wasn't talking erp, you were.
thekey beeing isotropic
in fact .. i think you said something like "an antennae cant make it illegal there is no FCC restriction on any antennae"
That I did say
when infact, the very opposite is true
other than height for FAA stuff
Jymmm: on 2.4 wifi you have a limit of 20dB
if your card does 17 dBm
if you get a licence for a radio station, it will state maximum erp
and your antenna - losses = 3dBi
many of the ham bands do too
then you have 17+3=20dB
alex_joni: actually, wifi is more complex than that ...
but if you have an 20dBi antenna.. you arecertain to exceed that value of 20dB
for each 3db over 16db of antennae gain, you only subtract 1db from the tx power
robin: I know, was only keeping it simple
and you might connect your high gain antenna to tx
im just suprised Jymm has never read his ham regulations
do you really think I'm going to alter the design of an antenna, or tweek the tranmitter?!
"Oh no, this antenna is desgined too well , let me use a shitty antenna instead so I cna be legal" I don't think so
no of course I dont ...
"Ok, wifi is the ONLY time I've ever seen that has an antenna restriction per the FCC Rules" ...
Jymmm: there are antennas out there which in combination with amps are illegal
that is if you don't set transmit power accordingly
alex_joni Di I say antenna + tx? No, I said antenna. There is no such thing as an illegal antenna.
think swap meet... you can't buy an illegal antenna.
Jymmm: OK, can I ask you .. whats the power linit on 60M band in the USA?
of course there isn't, only using it makes it illegal
I can have a 200W amplifier for 2.4 in my backyard
robin_sz I'l only a tech, so I'll say 1500 PEP
switching it on makes it illegal
Jymmm: nope, 50w ERP
alex_joni no it doesn't
I dont know about you guys, but my radios have a power level switch
besides, you are suppose to run lowest power to maintain communications.
well, thats one view
the other is that its rude to be weak ;)
turn the m into M
that would be CBers then, you a CBer robin_sz ?!
he-s a HAMer
might be ;)
I used ot do a fair bit of vhf contesting
thats sort of knowing the rules, and then breaking them to hell and back :)
[18:57:58] <Jymmm> http://www.ce-mag.com/archive/1999/julyaug/case.html
heh 6dB antennas
and 17dBm emitters
not very much
17dbm on 5.7 is not trivial
I have a 10w twt on 10G ...
but its such a pita ...
I ahave a 7w solidstate brick on 13ghz I want to down-tune
ooh, this taunting Jymm is fun, I should have doen it before ;)))
robin_sz when you figure out how to alter a pager to run ARPS instead of POCSAG, let me.
im sure its been done
a friend of mine built some very neat pocsag logging gear
pete bear ...
Yeah, I've seen em. But I want a pager.
I wnat dancing girls
then I can send stuff to it...
just send pocsag then
sports scores, weather, whatever
cant send pocsag over ARPS, the protocolos are incompatable.
(already looked into it)
well, why send it over arps?
I can be anywhere in the coutnry then
ermm, can pagers transmit?
No, but they can Rx
so.. exactly how will that work then?
arps is a bidirectional routed protocol
it's doesn't have to be bi directly
it need sot know where you are to route, and it needs an ack
you broadcast WX, that's not bi-directional
thats slightly special I guess
you broadcast your position, that's not bidirectional
well, it is at the rx end
If I dont want to ACK, that's fine.
well, I cant imagine the protocol will allow you to send your sports scores et to the entire country
that would make th enetire country one cell/channel
it woudl be full PDQ
I'll leave you guys to sort this out
im bored now ..anyway
Jymm is too easy to wind up
must go and beat the wife and shoot the dog,
don't forget the kids...
well back from town
forcast for our spring festival: rain all day.
Anyone using axis as a frontend?
les: I thought you were in GA not OR. :)
how's it going?
anonimasu: You talking to me?
now back from some mowing.
pollen is killing me though.
I knew I saved some of this surplus crap for a reason.
and I have to work on the cars after the spring pollen...radiators...heater core...air filter...usually clogged
I have a good bit of surplus crap too
I found the surplus Endevco accelerometer that I got a few years back and realised it would make a great sensor for a spin balancer. :)
Accelerometer + encoder + geared up drive motor == High speed balancer. :)
what is it? a quartz tri beam type?
With the addition of a scatter-shield and some frame it should be OK.
I have a dozen or two of those analog devices accels
got em as free samples
Not a clew.. It's a little stainless cylender ~12mm D x 15mm L
well what does the output look like?
that will be a clue
Jymmm: And what in the hell do you want???? <JK> :)
Jymmm: Forget it she's mine. :)
oh I imagine the code fest thing is over huh
Hehehe... By the time he figures that out I should be long gone. :)
les: They are an analog out.. I was using the adc on a pic to read it before.
Phydbleep You can have the ewe, I'm not into beastiality
quartz usually needs a charge amp
Jymmm: They trusted ewe.. :)
This was a straight analog signal.. I could yell at the accelerometer and get a reading. :)
Phydbleep did you do the acetone thing yet?
I have some b&k impedance heads somewhere
I think it is a real old one from Sandia or White Sands.. They use a lot of them for vibration detection in engines/equipment.
Jymmm: Not yet, need to pick up a 'brayer' (Ink roller) for burnishing it down. :)
I've did a similar proces on glass with photo stuff years ago and got good at getting the image sealed down without distortion or bubbles..
I think if you just make a snadwich, you'll be fine.
instead of needing a roller.
acetone loves to dry out rollers
doesn't effect PET though
I want to be able to get all the bubbles out and the roller is an expendable item..
get it laser marked into annozied aluminum
Plus I have a sheet of teflon film to lay over the parts to protect the roller. :)
Jymmm: Anodize some transparent aluminum for me and I'll try it. :)
oh your not doing reflective?
Transmissive.. It's the only way the pwm band will work.
I'll have ~ 2x the thickness of the acetate between the pattern and the sensor. Acrylic> pattern < Acetate < Air Gap.
how thick acrylic?
you wont have any issues with optical deflection?
1/8" for the test.. 3/64" (I think) for the 2nd test.
