    I am a drummer at Florida State University, and my bands will be playing
    around town soon. I would like to create an effect like the one found at

    Specific instances are found here:

    I have a few questions:

    1.) What kind of sensor would one use to trigger an LED light to illuminate
    for a brief moment whenever, say, the bass drum is played?

    2.) I am also thinking about setting up several small strobe lights around
    the drum set,
    --similar to the one found here:
    and I would like to have a single switch control all of the lights. While
    keeping this as simple as possible -- I have never built electronics like
    this before --, I would like the lights to go off at different speeds so the
    lights would look more random and jittery, rather than the entire drum set
    lighting up at one time. The timing is less of a concern though.

    Any help would be greatly appreciated! Thanks!

    Simplest solution would be any kind of jury rigged (or better)
    switch attached to the pedal - probagbly a momentary contact N.O.
    switch like a microswitch you'd find in a microwave or any of a
    number of other applications. Prices IME vary from $7 from an
    appliance repair store to IIRC, $0.50 mail order
    Set the strobe rates differently for each strobe light and plug tham
    all into what we ( band called Haji - later Hybrid Ice - from PA )
    called a quad - 2 wall outlets in an electrical box with a power
    cord running to the lights panel. The switch ( a light switch - wall
    switch ) would turn the power on to the quad. You could leave the
    individual strobe switches on, tape them down, or just solder a
    short across the switch contacts.
