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

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.

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:
