He said he got 2.7 turns , instead of 1 ...
ok, the point is, you see it as a hardware prob, its a new install so i wont disagree at all
Not good to get ahead of things...best to do the measurement first ...
i dont have the chance to do the exact measure :(
But, a loose ground could generate ground noise and add extra pulses, from AC even, if its a CMOS input....when we get to it, he might try 10 K ohm resistors to improve noise...
unless you can tell me how
wb9mjn: not that, ive learned that !
I used a caliper against a fixed portion of the machine...then pushed out the caliper head till it touched the table...
whats your caliper ?
before and after the movement, record the difference...do it again, in the same direction....
rcsu: check google ;)
not sure how it's called in german
Should get within .03 mm ...
caliper is a measuring stick, with dial indicator ...
rcsu: you could even set the moving speed very low, to get about 1 pulse/second
Starrett, Mitutoyu, Brown and Sharpe ...etc ...
and actually look at the stepper
and see what's happening
If you see varations more than about .5 mm, and random, you probably have hardware problem...
electronic hardware problem...
make that .2 mm ...
writing teacher ?
alex_joni: ok, 1 Pulse/s
schreiben is writing
schieben is pushing
rcsu: might be also a bit more, but you get the idea
well, last time I had German was 30 years ago, hi..
1mm/min = 400 pulses/min => 6.667 pulses / second
so you need about 0.14 mm/min for 1 pulse/second (if INPUT_SCALE is 400)
rcsu: the alternative would be to start only HAL
and set up a stepgen with the exact frequency you want
alex_joni: thats wrong, 400 pulses/mm
and use that to drive the motor with 1 pulse / second
ill try that 1 pulse /s
rcsu: if you travel with 1mm/min, and you have 1mm=400 pulses, then you get 400 pulses/min
thats MAX_VELOCITY = 0.0025, right ?
you can enter in MDI: G1X1F0.0025
too late :)
but 0.0025 is a bit low
you enter speeds / minute iirc (or was it per second?)
In EMC 1 its /second in the .ini and /min in the G code...
F100 would be good in Metric...
equivalent to 1.666666 in the .ini ...
Or F60, for one turn per second...
wb9mjn: he has the ini in metric
don't confuse him even more :D
F60 should mean = 60 mm/min
That s how I set up my MF-70...I am talking metric...
1 mm / sec
but he wants 1 pulse / second, which is 400 times slower
wb9mjn: no problem, thanks for jumping in
<alex_joni> so you need about 0.14 mm/min
wb9mjn: rounding errors :D
Should see some good resonant behavior on the motor axis if you have a knob on it, at that speed...bonk...bonk ....bonk....
If it wiggles, rather than just steps, that s another issue that may force you to a microstepping drive...
hum, i counted 39 steps for ~90 degrees
What was the X , 1 ? G1X1F.15 ?
40 steps ~90 degrees -> 160 steps / turn
with your set up 400 steps / turn -> 400/160 = 2.5 (just about right with what you said earlier)
so my guess is that the motor is not 200 steps / turn
Are you sure you have 200 step steppers ?
or maybe the drive is not half stepping, but it is multiplying the pulses (unlikely)
78 step steppers were common at one time...
no, they only say microangle steppers
but 788 != 160
76 != 160
78 * 2 = 156
So were 39 ...for the big 8 inch floppies...
pretty close I'd say :D
39/2 times 4 =78 ...
if you have a 78 steps/turn motor, and half stepping
400/156=2.56 (even closer)
micro-angle might be how accurate they are ...hot how high a resolution...
78*2 =156, instead of 400 ?
Try that ?
thats very close to what i have observerd !
thanks a lot
rcsu: not the software after all :D
yes, the BD between my ears :)
I see that the stepper configs don't start here.
good idea to do the 1 pps thing...
wb9mjn: yes, too bad it's that hard :D
more & more I start to like the feature request a user had
to have a wizard helping on the setup
for exactly stuff like this
screen says: push the limit X+
measure distance traveled on X
emc commands 1 mm, user measures
emc commands .5m, user measures
like a wizard
Your steppers are probably surplus from double or quad density 8 inch floppy drives...
advanced users probably won't use it..
I remember playing with 8 inch floppies as a child
Well, not so much for newbies, unless they are converting a Sherline to EMC 2 ...
some 15-20 years ago :D
you keep saying that..
I've still got a toaster full of 8" floppies on the first unix box I ran.
Hi, is ham radio slang for ha ha ha ha...
but thats a basic test, to get the resolution of your stepper / revolver
Can t get out of the habbit...
what must be done do do such a druid ?
hrmm.. for that we might need a thingy to convert the ini
no, thats for advanced users
a druid is for nebees (like me)
Need something right to convert in the first place, for it to be useful for newbies...
For newbies, need more like a GUI configuration utility...
yes. like I described above..
Ask questions, (menus) with fixed selections, and fields for variable entry...
Oops...missed it ...
it's in the wiki (under Features something..)
not a conversion utility ...
with a pointy hat :D
and a beard (rayh ?) ...
wb9mjn: behave :P
the prob at all is the faulty hw and OS setup
its hard to guide that with an wizard
When I proposed a wizard I seem to remember someone saying "if they don't know what they are doing with the ini, they ought not to be trying."
yes, and one that can take care of all the problems is unlikely to be built
we might want to change some views regarding 'customers'
but maybe an online knowledgebase is ok (like the wiki)
Well....we had the same sentiments with NOS..(Network Operating System)....but now Windows Network stuff is all by menus, and some wizzard stuff...
a wizard done by 1-2 people has no chance to get all the cases are usually found, but a cooperative approach like the wiki might
But, then , a mess up there could screw half a state packet radio network....
thats not the leage your are playing :)
K4ts_ is now known as k4ts
not crash a machine...
rcsu: no, we are a bit above that
* rcsu grins
I'd say emc is far more stable than doze :P
and I run both..
what is doze? ;)
NOS ran on DOS, and was a TCPIP stack for the early ham networks...it was OK reliability wise...
It was closely modelled after UNIX IP stack, before Linux existed...
its not a q of stability nor of usability, its just a q of simpliness
wb9mjn: was there a time before? :D
rcsu: different users look for different things
Maybe not for you ?
wb9mjn: sure there was.. I had a nice Spectrum in the beginning :)
* rcsu is a Linux user !
rcsu: some want an easy to use desktop machine
others want a very robust industrial-grade controller
which is OK to be hard to set up
after 10000 windows wizard connection sharing is working !
damn wizard :/
Jacky^: you're just about right in the conversation
but if you want success, you need the stupidness setup of windoze
rcsu: depends how you define success
remember it's all GPL
The Debian Linux on a 700 MHz plus machine is not too shabby...
set up this in a klick :)))
maybe one developer won't get his kicks by how many users use EMC
Not a big fan of Red Hat though...
he wants a software that works for him, and only for him.. which is ok
oh alex_joni thats not a success
speaking of internet - just found out today that we can get fre long distance, answering service, and 1.5mbs down (was 768kbs) for a dollar less than we are paying now. (phone company/dsl) I think we finally have competition in this area.
a good software works for other setups too
rcsu: again, that might be your definition..
but it's a free software project
so everyone is entitled to work towards his goal
alex_joni: but you cant get broad success until you say your own thing is it
I might not care about broad success
let's take a scenario
I want to sell plasma tables
and I want to use emc as a control
my goal is to make it industrial, ready, etc
its far bejond done
there are still some issues
For 2 D stuff its probably OK, unless your doing high end routers like les...
but that's not important
yes, plasma is out
For 3D, the TP needs work....
wb9mjn: for any xD the TP needs work
Or at least that s the concensus...
if I want to do plasma cutting I need high speeds on thin sheets
think that way towards LCD displays
like 1-2 m/sec
BenQ is nearly to that timings
rcsu:that's another thing.. I might want a touch screen GUI for emc
If you do not maintain speed the same everywhere along the trajectory, does that widen your kerf ?
and it affects the quality of the cut
So, for a router with a fixed bit with, its more forgiving, unless you have hardware that can go megafeet/min , like les's and thermood...
you have one optimal cutting speed (depending on material, current, plasma gas, etc.)
wb9mjn: well plasma is usually m/min cutting speed
not that fast
fixed bit width...
but a laser.. might be faster
seen some nice 12kW lasers lately.. they go through steel like through butter
no, a laser in this context is really slow
not a 12kW laser on .5 mm sheets
cutting away at 2-3 m/sec
you need the speed to 'ablenken' that power
you'd be amazed how they work these days :)
and to controll the lighning
thanks for your help !

* Jacky^ upgranding his laptop 40.3kB/s 3h32m15s
bleahh slow dsl here
Jacky^: I gaveabout 1.5 kB over here :D
IF thereception is
really - what time is it there - it would be considerd breakfast time here.
yeah.. but I was up till 3 am
take it easy
jacky - my wife just found out we can get 1.5mbs down + answering servic + free long distance for a dollar less than we have been paying for our phone service. (used to be 768kbs)
must be competition around here now
skunkworks, good .. :P
here are atlaking about voip since 2003 ..
but it wont to take the fly
too much business conflict
I bet - it has been a round. vontage is one of the popular companies
k4ts is payng E. 45/mounth for dsl 1024/256 ..
is that just dsl or dsl + phone service?
with no phone line
just dsl line
wow - well I really don't know what we are paying. (shouldn't talk) ;)
same dsl of this in France cost about 15 E.
heres Telecom Italia, there Telecom France
wow - I know it isn't 15 dollars here - maybe 30 or so.
hell people are paying 25 dollars for just dialup aol lol
it may depend on speed too ..
I live out in the boonies and ran directway satellite for a few years before dsl (2 way satellite internet)
uhm.. my cousin live in a mountains zone, there is no dsl cable line there
he tried with the satelite kit but hes disappointed
a bit faster of 56 k line , he sayd .. :/
yeh - ping time is around 1 second on a good day (damn speed of light)
but I could download at a peak of around 4mbs upload was lucky to be 50kbs
for download maybe is ok .. but for upload is bad
then there was snow/heavy rain outages. Oh and the 168mb download cap per 8 hours ;)
but it was better than dialup
plus the high techness of it :)
(transmitting to a sattelite - cool)
are you able to do that ?
my cousin was using phone line 56k for upload ..
not any more. ;) dsl is so much more stable.
yep - that was an option also here. although they where trying to phase it out
they called that 1 way satellite
the issue we have here is for upload, too slow
we just have offers with poor upload band
I hope antitrust will move a bit in the next year ..
I have 256kbs - have not tested it though
theyre breaking the progress, really :(
both here at work and at home
yes, on the paper ..
like I said - never done a speed test
I do it every mounth
im having trouble to use skype too
do you have the option of cable internet?
for the same reason :(
theres some isp selling dsl via optical fiber
but youve no public IP
are in a big lan ..
I think theyre going to copy US style
all in one cable, dsl, tv, etc..
wow - interesting - that is how I was on direcway satellite -
no public ip
public IP and a lot of features are available as options
we have static here at work which is really nice.
yeah, this where Im now (k4ts) is static too
but she pay about 4 E,/mounth for that
right - it is extra here also
and I think they still block port 80 outgoing so no web hosting
uhm, no, we dont have any block
(might be a business thing) I don't know
yeah, probably it is
launch time ..
;) eat well
I assume you ment lunch - not launch (like a rocket)
connection losted :(

hi jepler , alex_joni
rain & rain
I wonder when we'll made some nice photo here around :(
planning to pass 31 night in a restaurant ..
are 100 E./people too much ?
dinner, dance, etc ..
it seem 80% of peoples will stay at home here , 31 evening
* alex_joni goes to build one of these : http://wading-in.net/Remote.html
damn hackers :P
anyway great camera ;)
im tryng to learn how to manually improve performance of my camera ..
im just using it in auto-mode
not good at all , with this bad weather
heh, bad weather is nice too for photographs
pics are dark , too dark
but it's a bit harder
im tryng to do a lot of pics using different settings
then compare the results..
yes, sony camera
then it should be fairly easy
it have 7-8 auto mode , and manual settings
yeah, it should be
but im pretty sure that to get good photos its an art
what are you shooting?
Id like to find best settings for dark ambients
like, hall, with neon light
and panoramics with bad wheater
use long exposures for both
but that means probably a tripod
yeah, tryng to get it as best I can ..
smaller apertures, and longer exposures
it also have autofocus
but in some case manual focus setting should be better, I suppose
very few cases
playng around all settings :)
ok.. I'm gone.. will be back later
shoot in Av if your camera has such a program
there you can set aperture, and it selects exposure
check google for tutorials :P
What's a comment in gcode?
all the coments I have seen for emc have () on each line

I solved the issue about to share connection ..
bought an ethernet router for $20 ?
nope, just using the windows wizard ...
after 3-4 wizard pass, I got it working ..
I was thinking iptables was available ..:(

what's up Jymmm?
nah, I broke the tooth 20+ years agoa nd it was bonded, just needs to be rebonded
knock on wood
so, found a dentist that can rebond it for $90, one quoted me $500
[20:04:15] <alex_joni> http://wading-in.net/Remote.html
just got off the phone with a oral surgeon that I saw 5yrs ago to get copies of xrays so I dont have to pay for them again.
just made one of these
$20 and wireless --> http://www.digitalcamera.it/catalog/images/ML-L3nikon.jpg
alex_joni_: 1/8" thick, $20 and wireless --> http://www.digitalcamera.it/catalog/images/ML-L3nikon.jpg
yes, there is one for the canon aswell
well, for $20 you just can't beat it.
Though, a corded RF remote would be nice too.
I don't know if the D50/D70 support a corded remote
Heh, I can remote control the camera via USB, but me neither =)
what's a corded remote?
alex_joni: you plug in a box to the camera, and the box is a Rx.
ahhh I see
oh a corded remote is what you built
20 ft cord
remote == away from the camera itself
right.. the rebels have USB, corded and irda for that
I never actually LOOKED if my camera has a corded remote jack, but who knows.
It's doens't have a plunger, that I do know.
but it has a shitload of jacks on it
actually the SB800 has the shitload of jacks.... was even able to trigger the strobe I just bought
which I thought was cool, but not TTL =(
cheapskates - buy a set of PocketWizards, increase my income... http://www.pocketwizard.com
alex_joni_ is now known as alex_joni
SWP_Away: No need, my camera has built in remote control TTL too
SWP_Away Nikon D70.... supports up to 4 speedlights.
yep - not that they'll work corerctly in fluorescent light
SWP_Away They do
though you can't use the remote triggering anyway - the D70 has no remote port, right?
I have a IR remote for it, link to pic scrollup
I've seen that - I was wondering about the standard 10-pin connector, like on the F5 and D1/D2
dont know, dont have one
I mean the D70
I think I checked that one for use in the camera array, and it didn't have the remote port
in any case, when I refer to "my old company" - it's the company that manufactures the PocketWizards
much much is a pair?
yes - much much :)
how much is a pair?
the Plus is around $300, and the Max is around $500 (per pair)
though they work at much longer ranges, and have loads of features that the in-strobe remotes don't
and they're mssing TTL at the moment
they lie http://www.pocketwizard.com/HTML/pwnikond.asp
well that's kinda/sorta useless
no D70 support =)
they explicitly list the D1, D1x, and D1X
diH, I mean
at least my SB800/600 have ttl support.
D1H - there, dammit!
they should have said "expensive D-Series"
though the D50, D70, D100, and D2 didn't exist when the product was introduced
(c) 2005 at the BOP
hello all.... trying out a new xmas laptop from bdi install onto the web in 5 mins
I suspect that's due to the header changing or something
So far, I'm happy with the internal IR remote flash
the flash isn't IR, I think - it actually pulses the flash tube to send commands to the remotes
no $25 cables to buy, no cbales to trip over
new camera??? Jymmm
dmess: Not new, alex_joni is though
SWP_Away: There is some IR on the SB800,
as there are groups channels and TTL too.
right - I just think they use the flash tube for signalling, they may be detecting the IR emissions from the tube (I may be thinking of how the Metz strobes work)
it's been a while since I was actively involved in that business
i got a nice new 2.99" reflective telescope with a max of 675 x magnification from my wife who likes me alot

we had 14 nights of clear nights from dec 1 to dec 23... been cocked in clouds since...
ive been looking at bird nests on the mall 2 KM away... just for kicks
i COULD see a boob thru a window but if it jiggled id lose it...
alex_joni I thought you got a 300mm lens?
actually a zoom, 75-300
alex_joni: must be grainy
Jymmm: not at all
alex_joni show me
thats a nice lens...
it's a bit slow (4.5 but works great)
anyone know the length of a standard cigarette?
I have a 18-70, then a 70-300
fenn Marlboro 100's == 100mm
dmess:it's the entry level 75-300, there is a 75-300 with IS and USM
80 mm id quite different
I have 18-55 and 75-300
and a few on my film SLR's
hmmm the new pentax slr IS SWEET...

i seen one in a cash converters for $245 ...yesterday..i left it to come down some more
huh? what's that in english? :)
yeah - gotta love the marketing types
it's a great feature though
sounds like a fun video game
pawn shop... 245 canuck buck===175 yankee buks
well - the old scopes in the series two (or three) before had Centipede and Tetris in them
$175 is a cheap scope
if it's any good
well - if you buy that scope for $175, I'll pay you $500 for it ;)
assuming it works
...and doesn't weight 85 lbs
the 6000 series is really light
they're smaller than the previous ones (I have a 54622D now), and that includes a compartment to store probes and stuff

ill go get spec and the likes first ...if it of use to some one... its here..
there's one of these on eBay right now for $10k - I may get that one instead, if teh guy tells me what options it has, and I have the opportunity to check the serial number for "irregularities"
I'll stick with my antique Tek 466
much less expensive that way
christ - they're selling those for up to $1k
doesn't surprise me
I just did a quick search, and see prices from $250 or so up to $1000
shiite im goonn go grab that one
it surprises me a bit, considering that it's an analog storage scope (right?)
I really like it
we used those in the military, 20 years ago ;)
and I think they were old then
and they're all still working, maybe I have the one you used to use
if it has a tag saying something like "AN/USM 575", then it might be ;)
STILL WORKING... operant words
but not quite fast enough, or with enough channels, for newer (faster) designs
well I'm a hobbyist
in that case, it's plenty
use guys ever use a keyhole bit?
got quiet in here
that's "t-slot cutter" to you, mister
fenn "Yes, Dear"
Could you check this please....
well, there's a lot of repetetive stuff, but it looks like it does what you want it to
Well, something fubared last night when I ran it is why I asked.
you are cutting the slot first with an endmill right?
um, no. (wood)
it's that the purposes of the upper cutters?
cut the slot first, then use the slot cutter
it's not really meant for cutting
ok, what am I missing here?
there really are upper cutters on it.
i believe you
when doing it on metal one always cuts the slot first
it might work in wood without the slot, since you can crush the chips inside the hole
to get the correct surface speed/chip load for the major diameter - the small diemeter will have too much chip load.
Yeah, it did scream like a banchee last night.
do you cut a 2 inch slot in wood at two diffent hights? what happened
no, one height.
does my code show two different heights?
* Jymmm first hand written gcode btw
no - I lost it after the last z.2
what did it do that was wrong?
z.2 iirc is "safe height"
well, it WAS .4 instead of .375
so that ripped the piece off the table for one
its sinometer yb4328 20 MHz 0-scope
it was way too deep, than it should have been, and I did measure it too.
skunkworks so I think my code is fubared somewhere
what shape you trying to machine>>
the code is fine, at least in theory
feeds might be wrong etc
dmess this shape ---------------------- =)
skunkworks no 1
how BAD can your code be...???
dmess scroll up to find out =)
did you do a g92 in mdi to set the hight you wanted for z then run the program?
fenn - right
what you see is what I did
that is why I was asking - does some funky stuff
guys from my perspective g92 is unnecessary... and the cause of alot of issues
z=0 was the top of the blank right?
how thick was the t-slot cutter?
how was it held down?
wouldn't -.375 cut right at the surface then
when I look at the piece, it went at least .1" more than it should have (deep)
it sucked the mdf UP that far my friend
i'm thinking the shaft was pushing on the un-cut mdf at the top of the cut
maybe not enough chip removal
the cutter needs ver fine plunges to avoid grabbing
when the chip builds up and adheres
dmess this is mdf, you aren't gonna have any chip buildup
fenn maybe no place for the chip to actually go... as still in the recessed slot
if you are more than 4:1from where you are clamping.. it will suck UP though
Jymmm: yeah you could try "pecking" like in a peck drill cycle
but moving sideways not up and down
hmmmm, never considered a keyhole to be so envolved =)
fenn I see what you're saying there, to clear out some of the chips
not the best pic, but this is what I sorta have... http://sherwoodcreationsinc.com/images/products/X-181.jpg
i dont think there will be enough relief on the upper cutters to allow easy cutting
so it pushes the piece to the side, then when it backs out it digs into the rear wall of the entry hole and pulls UP when the bit retracts
or something like that
fenn: ok, so endmill, then keyhole bit. Both using the same gcode above should do it?
the endmill should help with chip extraction too
Are keyhole bits meant to upcut the larger hole upon extraction? O---------------O
this one does have cutters where that would be this is why I ask
look at the relief on the top edge of the bit
if it's angled, go for it, but if it's a 90 degree angle it won't cut anything and will probably break something
* Jymmm grabs loop
It's the same angle on top as it is on the bottom.
like a bowtie?
er, half a bowtie
well, only one way to find out
i'd be worried about chips clogging in the hole on the way up though
what is the hight of the slot that it is supposed to make?
fenn didn't think of that.
from surface to max depth is .375"
right - but what is the dimention of the cutter? 3/8 by what thickness
jymmm try it on blue styrofoam or wax first to see what happens with the chips
if they melt, that means it won't work on mdf
skunkworks 3/8" x 3/8"
fenn an the old mel tthe shit out of shit test =)
I like it =)
i just thought of it
Well, though it's a PITA, your endmill+tslot I think is KISS
well you gotta do a toolchange already, what's another toolchange
What about my feedrates ?
skunkworks 8k to 25k
I went slower on them to do minimal damage to the finished piece
.375*2pi*rpm*feed/12 = sfm
so then what is a good sfm for mdf?
(I don't know)
er whoops that formula's wrong sorry
there's two factors, sfm and chipload
.375*2pi*rpm/12 = surface speed
in IPM ?
heh, was just asking that
that's a different concept than feed
it's the speed of the cutting blade relative to the workpiece
divide by 60
ipm/rev/number of teeth = chipload
I really have to program that into my calculator sometime
ajoni is now known as alex_joni
need one of the need slide calculaters - quick and easy
.006 to .010 seems to be the rule for mdf
OT... it's sad that HP only has 3 calculators anymore.
feed = 48 to 80 ipm at 8000 rpm, can you do that?
but not so slow that it'll friction char the piece
80 ipm is a lot faster than i expected actually
fenn I can do 200 IPM under MS-DOS =)
i think steppers are a dumb idea
fenn: depends on the application
in some areas they are the best
well, not cnc milling machines
dmess: stepper motors
Yeah, and Mariss fucking with me about them =)
or his stepper drivers that is.
stepper drivers are fubared??
it was a thread on the yahoo gecko groups when I asked MAriss if his drives prevent mid-band 100% or 99.999% of the time and he said 101% of the time.
as the dukes say... kill em all.....
i'm making a gun.. a revolver
it shoots cigarettes
you stick the gun in your mouth and pull the trigger and it blasts a flaming cigarette into your mouth
fenn: into your guts :D
through the stomach
relatively weak explosion, maybe 20 ml of air + 1 ml butane
at 20 L and 1 L we lookin for a fine BOOM
yeah but this is pointed at your face remember
i'll be surprised if it actually works
i wanna see before and after pics..
dmess: of his face?
i would think thats where the stuffs gonna happen... i figure
probably won't notice anything
i should get to try my new telescope tomorrow night...maybee... please.... ;(
heh, I have one too
but I guess I don't have time for it :)
make time for the cosmos cause it makes time for you
there is a messier marathon in february...
I'm not sure how to use it though, never made the time to figure it out :D
i see... my wife got me a nice 3 " reflector telescope for xmas.... i love that woman...
so i dont know how to use IT either yet...
I'm not even sure what kind mine is :D
I know it has a mirror inside
about 8-10 cm
sounds about the same..
* alex_joni hunts for a pic
big barrel that you look into the side of??
is the image upside down??? or have you even noticed??
I looked at the moon once
wasn't that thrilling :D
except it was very bright
LOL... mine needs a Barlow lens to rectify the image upright
and the MOON is way bright with any reflector scope yes

mine has a 900mm focul lenthg as opposed to 700mm... all else looks the same
wonder if I could fit my camera and take some pictures with it
im planning on trying...
ok, let me know how it goes
also.. watch out for robin_sz, he seems to know a bit about teleskopes
i tried to view thru the cel the phone cam the other night... but i was tooo drunk... lol
even with the 20mm lens its a far shot
how do you plan on fitting a camera to it?
i was thinking of a light web cam and a piggyback mount
how about a serious cam?
serious cam need serios mounting... to be able to focus on the mirrror directly
mine is supposed to be mobile to all extent so i cant build too serious
but the proper combo of tube length and lens.. sufficient electrical tape.... and support ... is all is needed
this looks nice: http://www.astroworks.com/
heh i wonder if it has adaptive optics
probably a little out of my wifes price range...

my 14 yr son got a new guitar... 11 yr old daughter got a keybord... and the middle boy has stopped singing since xmas... someone TAKE ME AWAY...

nope, you use some markup
like [title this is a title]
