    Hey

    I am trying to make a dancing water fountain (meaning a water fountain
    that moves
    according to the music) and also that lights up (eg leds) according to the
    music.
    Anyone can help me please? Any circuits or ideas will be appreciated

  2. This idea was around more than 40 years ago. They called it a "Color
    Organ".
    Linear time is kind of boring and not very artistic. There might be
    better ways.

    Then I was in college I built a stereo color organ that had two 4'x6' displays
    using C7 Christmas tree light strings behind a plastic diffuser. The displays
    were mounted on our living room wall above the speakers.

    That circuit is either overly complex, or, does a much better job than
    the 'Musicolour', a magazine (Electronics Australia) project I built
    as a teenager ;) The musicolour had three channels and the bass channel
    beat with the mains frequency on some sustained low notes, quite strange.

    Is there a description or spec for your disco circuit somewhere?

    I would have liked a beat option back then :)
    I didn't mean complex in a bad sense, more in that it makes me wonder
    what the thing is doing it is doing with the extra parts, compared to
    a few simple bandpass filters driving triacs.
    Well, I been away from electronics a long time, and your circuit seems
    to do a lot more than others I've seen. Didn't recognise state variable
    filters.

    Last ten years my work was mostly embedded controllers and very little
    support circuitry. The fun analog stuff I did in measurement and
    control systems was in late '70s early 80's.

    Now, two of us think so.

    SWMBO wants to buy me a tee shirt printed with an upside down logo
    that I can read easily:

    "Shut up. You are not funny."

    :)
