Hi,

Not sure if this is the correct group to post this query to or not -
but here goes anyway!

I am looking to install some disco lights into some decking in my
garden - does anyone know if this can be done? If so - what is required
to do this? And where might I source this?

Not looking to do anything too 'special' just something straight
forward, and hopefully not too costly, for my son (and me) to have some
fun with!

Any help offered would be greatly appreciated

Are you asking for a 'lights in the floor' dance floor, a spot light on a
spinning disco ball or just exactly what?

You will probably have to have a new source of power run from your
breaker panel but that depends of the total power consumption. Other
than that, it's just a matter of running the wire and connecting it all up.
Of course, it all must be weather rated and grounded.

also they made ceramic caps at one time that

that is what you want.

Most of the high end Agilent and Tektronix network analyzers and spectrum
analyzers are now just regular old PCs running Windoze along with various
specialized plug-in cards to perform the data acqusition.

There is notable value in having it all 'packaged' nicely and the installed
software being guaranteed to work and the thing not taking over your desktop
PC, of course.

Yes.

Assuming that the amplifiers are op-amps, then having two, each with
lower closed loop gains, will result in great overall BW. This is
because that closed loop BW of an op-amp is inversely related to its
closed loop gain.

"Mobile Phone EMF safety concerns becomes an Insurance risk for telcos"


Our group is currently fighting a major telco that wants to place 6
mobile
phone towers next door to a primary school and within 500m of 7 others.
Despite current talk about safetly levels and standards, we feel that
not enough is known about mobile phone tower EMF to justify this
situation.
According to Australian Federal Law, Telcos are excempt from
town-planning
and local government laws and moreover, do not have to consult with the
community or private property owners before installing these towers.
While C.R.U.S.A.D.E.R (TM) IS NOT AGAINST MOBILE PHONE USE, the
unhindered proliferation of microwave EMF is a
major concern due to its unknown long-term biological effects,
including the possibility of cancer.

Due to the recency of the technology, Mobile phone EMF safety has not
been edequately confirmed and what research has been undertaken is
essentially incomplete. Therefore, while we believe in the just and
democratic freedoms of the pursuit of wealth, we also believe in the
universal rights of man, which grant each and everyone of us the right
to "a standard of living adequate for health and well-being", including
protection to mothers and children (Art 25) and "the right to a healthy
and balanced environment (Art 28)". Unfortunately, these rights are
being violated across Australia by a lack of corporate responsibility.
This time six towers will be erected literally metres away from
schools, private residences, public libraries and a nursing home on
the basis that EMF is innocent until proven guilty. Unfortunately,
society is not a court of Law and on this issue we have gone well
beyond the point of reasonable doubt. Safety is not a gamble, it is an
investment in our future and one that must be protected at all costs.

Furthermore, safety is the preceptor of health, which the World Health
Organisation defines not only as the absence of disease or infirmity,
but also as "a state of complete physical, mental, and social
well-being". How can this be achieved when a parent is concerned about
the multitude of detrimental effects attributed to the phone tower
radiation, including the real possibility of cancer, upon their
children? In fact, a threat need only be perceived as harmful in order
for it to be so, it need not be real at all!

Insurers Baulk at Mobile Risk
An April edition of the Observer reported a leading Lloyds underwriter
as
having refused to offer product liability cover to mobile manufacturers
for
damage to user's health. The firm cited the striking resemblance
between the
development of the asbestos and tobacco health issues and the current
mobile
phone problem, both of which will end up costing insurers a fortune.
Recently the giant Insurance group Swiss Re stated in their publication
Electro-Smog A Phantom Risk, that on the basis of today's present
knowledge
alone it must be expected that a EMF claim would succeed. This view has
been
supported by the recent exit from the re-insurance market of
Scandinavia's
biggest insurance group, Skandia. They cite reducing exposure (sic.) to
potential EMF claims as being one of the reasons.
In this regard, corporate providers should guard against complacency in
relying on present day government advice to protect themselves against
any
future potential liabilities. The experiences of the asbestos industry
is a
sobering reminder of this. Although a manufacturer will always be
ultimately
liable for it's product, it is inconceivable that an employer
insistent upon
it's work force using mobiles, would be
totally exempt from involvement in any actions for damages by
employees.

I picked up some of those GE Reveal(tm) bulbs, touted to hand out a
more balanced spectrum. It makes the room a little "whiter", but it
doesn't seem to make much difference reading the resistor bands. Oh

The daylight-balanced tubes we were using made the light
look "redder" to my eyes, not "whiter". It really was like the
light you see at dawn. I'll find out what model tubes we were
using and get back to you.

I'd be more concerned about the danger of the towers falling over
in high winds and hitting the school. Or the psychological damage
from having such an eyesore in view. But as far as credible
evidence for dangers from EMF, you may as well worry that
the emisions will attract hostile UFOs.

First, you have to define "disco lights". Some of us have never heard
the term before, and most of us who are old enough to remember "Disco"
would rather forget about it. ;-)

Good Luck!

You're probably correct about non-sterile hypodermic needles but nothing
is stopping its reuse!

I saw a series of micrographs of the point of a hypodermic needle, amazing
how dull it gets after just three uses. This makes me wonder about how bad
the needles were in the old days when the tools were autoclaved and reused.


I have knelt down in the lab, stabbing 13 pins of a 16 pin dip into my knee.
Talk about ouch!!! I had to use my pliers to remove the damn thing.

Hi guys:

I have an application where I have 24 independently-operated push
solenoids
(very small tubulars) that are rated at 12 Vdc, continuous operation. To
make them operate properly in my device, I need to deliver a 4x voltage
pulse (48 volts) to the solenoid for a very short period (maybe 10 ms)
then
revert to 12 V to hold the solenoid extended while it is in use. This
must
occur every time it is fired. I will have both 12 V and 48 V sources
available on the PCB and the circuit is controlled with CMOS.

What is the simplest way to do this? Thanks for all replies.

Don

Click to expand...
The cleanest way to do this is with one or more microprocessors and FET
drivers for the solenoids. The solenoids would be run on 48 volts. The
microprocessor(s) would pulse the solenoids on for the required pull in time
then go to pulse width modulation at one fourth duty cycle for the 12 Volt
equivalent drive. There would be 24 input ports and 24 FET driver ports with
the timing for the driver periods controlled by counter registers for each
driver. A couple of PICs could easily do this. The PWM frequency could be
20KHz. Futhermore, being coded, the pulse width, 48V time and other factors
can be easily be adjusted to get the require performance, not easy with
capacitors or other ideas.

You can't prove that no risk occurs (if that is what you want) but you can
assess relative risk which is extremely low (e.g. compared to fumes from
