go,
Back in my highschool days, the electronics club of the school had
made a simple strobelight for the week-end parties.
Generally the kind of circuit you are describing consist of two sections.
One if the circuits that separate the sound frequencies and produce
a control signal for each band, generally about three. The second part
takes these control signals and makes the lights flash, The most common
lighting I've seen are colored incandescent types. I've never seen
fluorescent
tubes controlled in this way, after all one synonym for slow is 'tube light'.
voltage pulses which, when they were fed through an induction coil
from a car, were used to light-up standart fluorescent tubes .
I've never seen this type. The more common control circuit that I have
seen, mostly in mag articles is a triac whose trigger input is controlled
by the above control signal. Finding a suitable car ignition coil today
might be problematical, not to mention bulky since one would be needed
for each set of lights.
I want to use 10-15
fluorescent tubes
See my 'tube light' comment above. I suppose the triacs could be used
to control the tube lights in the same way as they control incandescent
types. Almost every hobby electronics books has this kind of circuits.
And magazines have them every so often. I suppose the frequency of
their occurrence is an indicator of their popularity. These days however,
I think laser lights are used more often. The idea is certainly not new,
they had something similar way back in the 20's dance halls, though
I don't think they were controlled by the music.
from MIDI. I want to use fluorescent tubes
The music to control signal part of the circuit will be the same regardless
of the kind of lights used. And if the lighting operates from 120 VAC
the controller too will be the same for each type of lighting. If you can't
find a book on hobby electronics or a magazine article, there is no doubt
a circuit at some sight on the web. I probably have at least one in my
'tronix
files but at the moment they are in disarray.
