phonic intermittance problem

i am having problems building a device to interupt a high voltage
flow
of electricity.
i initialy tried to use an optocoupler, which i hoped would respond
to
an audio current as input - interupting the high voltage flow as the
frequency of the audio current increeses and dwindles.

however the optocoupler did not respond with any variation. it was
simply on/of in responce to a complete cercuit on the input -
regrdless of any current in the input cercuit.


alternatively i am looking at this sound operted switch
http://www.saburchill.com/tech/electronics/elect028.html


but can not understand which components i should buy.


basicaly what i want to do is have sound (as electricity) produce
quantitive variation in light (rather than sound).


many thanks for any help anyone could give.

I found a great Internet company - Cashfiesta.com - that
has created a product everyone can benefit from. They
pay you while you work or play on your computer. All you
need to do is keep their software - the FiestaBarâ„¢ - active
while you are online. They even pay you when your friends
are using their computers.

Cashfiesta was a program that paid to anyone who was online.
So this program was suitable very much for people that every time
online.
This program was free or free and did not have the risk anything

His procedure was as follows :
1. Join Free
2. Fiestabar download
3. Install Fiestabar
4. Login with Fiestabar

After Fiestabar was successful online with user we then try to get
animation the small child stayed proceeding in the place, if he
stopped or ran then please in the click of his child.
While he went in the place then points we will continue to improve and
every time 1000 points = 1$
Money will be sent to our address was minimal 50$ in check.

Unlike other companies, Cashfiesta gives you control over
how much money you earn. They have an individual

Hi, Benjamin. It kind of sounds like you''re looking for a "light
organ", a devive which increases the intensity of a light output based
on volume.

You seem to be kind of casting around here -- why don't you try a
simple kit like the Velleman "SIMPLE ONE CHANNEL LIGHT ORGAN" Order
Code: MK110. You just attach the input side in parallel with your
speaker, and attach the output side in series with a 120VAC or 240VAC
lamp (1 amp max.).

Velleman kits are available from many sources, and are relatively
inexpensive. Here's a link to the Velleman page, as well as the
manual:

Good luck
Chris
