HI'
I replace the ballast of the fluorescent lamp with capacitor the

is flash the frequencey is 50 hz is there is any modification to
overcome this problem ?

thank you for any help

There are a good number of reasons as to why a ballast is used (older
transformer-like version or newer electronic version).
You have tossed out the engineering by using a simple capacitor, and
wonder what to do?????????
My questions are: (1) are you sane? (2) are you ignorant? (3) do you
not know well enough to leave something that works (and that you
*clearly* do not understand) ALONE?

Hi, I am looking for a PC-based logic analyzer to read a signal with a

Ok, so you have a 1MHz sine wave and you want the digit 1 to be stored

Everyone who reads your post is gonna have a different interpretation

I'd recommend a LOT more specificity.

I am having a problem find a frequency counter/time interval analyzer
that is capable of the following

Reasonable accuracy at
* Measuring 15MHz signal
* take parts per billion (in Hz) at 10 Hz sampling rate

Is anyone aware of such an instrument. On the counters I've checked
out so far you are lucky to get ppb resolution in 1 or 2 seconds.
Someone else mentioned the possibility of mixing the signal with a
similar rate in order to get side bands and measure those. That is a
little outside my normal "just take the frequency" realm. How
difficult would that be if there is no equipment available that will
do the 10Hz sampling at ppb ?

Thanks.

Sometimes your first thoughts at how to do something are not optimum.
Try recasting the problem so you don't have such a hard measurement
problem to solve. Any time your exponent is "10", you've got a
measurement problem.

Explain what you're trying to accomplish and you might get some useful
ideas.

HI'
I am yar intellegence then I decide send my problem to solve it
for me .I want to make a timer circuit to control 4point with this
following specification :

1- point one connect for an adjustable time with(variable
resistance)then point one disconect aand point two is connect

2- point two connect for an adjustable time with(variable
resistance)then point two disconect and point three is connect

3- point three connect for an adjustable time with(variable
resistance)then point three disconect and point four is connect

4- point four connect for an adjustable time with(variable
resistance)then point four disconect and point one is connect another
time

note: my problem is how can make the first circuit (555) triger the
next circuit
IF there is aanother useful IC's to catch my goal then why not

note :I try this circuit but it isnot worked
right(http://www.tarrypin.dail.pipex.com/images/555Timingchain-yar.gif)
and I this component for each 555

pin1----gnd
pin2----10k resistance&in4148diode&connect to the next 555 pin 3
pin3----connect to a coil relay
pin4----connect to pin8
pin5----connect to 0.01 uf ceramic capacitor(the capacitor in between
pin 5 &gnd)
pin6----connect to 1000 uf&25volt electrolytic(polar)(the negative leg
is connected to gnd)&39k ohm connected in between pin6 & pin7
pin7----connect to 1 M ohm variable resistance in between pin 7&pin 8
pin 8----connect to the vcc (the power supply is 12volt adapter)


I want any help

just sh*t-can the thing and get a unit which uses inkjet--or better yet,
laser--technology. I tried to 'get by' with one of those while I attempted
repair of my inkjet unit. I doubled my original investment within weeks by
buying the $15 OEM 'cartridges' which thermally transfer image to paper. I
used a few aftermarket (Office Depot) ones which didn't give quite as good
an image, but were $5 less...good enough.

The kicker was that the machine self-destructed on a genuine cartridge. The
off-brand ones just ran off the supply reel when exhausted. The 'genuine'
ones had the end bonded to the supply reel. Something happened to the 'end
detector' switch, and the machine kept trying to pull more film through
machine. Eventually, the pressure broke a tab on the latch which holds the
top of the machine down and popped it open. 'That' stopped it.... <g>

IMO, these are just stupid-tech. The $15 cart's only good for 150
pages...and that's pages through the machine--whether there's been any image
transferred or not. The film runs through the machine inch for inch with
the paper...exhausting the film at *exactly* 150 pages. You can rewind it,
but once used, you'll get absolutely no image from a used area of
film...makes for spotty prints.

My Hp laser machine shortly paid for itself in saved resources. If you only
get a fax or two a month, it might be worth having one of the thermal
transfer machines.

It is a lie. The poster works for ams.

And the message is ON topic in the newsgroups to which he

However, I do note that Mark's message is cross-posted, which is not

I for one appreciate knowing about $200 layout software if it's

When you say it has features like orcad, I assume you mean the current
version.
This alone is enough to send me running away, very fast.

Anyone tried this yet? www.pad2pad.com

The trial version is totally free, and does 10 x 8 PCBs - useful for

The difference with Eagle is - it's actually GOOD!

10 x 8 being cm (100mm x 80mm), which isn't too bad.

PCB is not really "fully featured", since it lacks real poligon
pour. To its credit, it has simplified implementation, which is much
faster and should be adequate for 90% of needs.
Click to expand...
What version of pcb did you play with? We've been adding lots of
stuff to it lately. I know of at least one board done with polygon
pour that I had to fix a bug for; there's now a key to clear-poly all
selected traces before adding the overlay poly. There was also a
recent bugfix for poly clears when multiple virtual layers were mapped
to one physical layer.

And if you do find a bug in pcb, please PLEASE report the bug to the
bug tracking page on sourceforge. We've been doing pretty well at
keeping up with the bug reports and fixing them, but if you don't
report them we can't do anything! There's a spot for feature
requests, too.

FYI I recently added an option to pcb to display a photograph as the
board background, which is something asked for here before. You can
scan a board from a magazine, do a little processing in some paint
program (careful cropping and color fading is about all), and use it
as a template to create your board.

We also have user-definable menus, sub-mil accuracy, trace optimizers,
and a few other goodies.
