OOOOOOOOhhhhhhhh tell me how, is it easy or complicated to make

If anyone has a rudimentary knowledge of electronics and is handy with
a soldering iron, it is very easy.

I wouldn't like to post full details on how to do it in case I got
done under terrorist legislation or something.

Anyway, about the simplest oscillator is a multivibrator, explained
here:

http://en.wikipedia.org/wiki/Multivibrator

By replacing resistors R2 and R3 with variable resistors the frequency
can be adjusted. The frequency range within which the frequencies can
be adjusted is determined by the value of capacitors C1 and C2.

Twiddle the resistors R1 and R2 to find optimum effect frequency.

The output can be fed into a simply constructed amplifier if more
power is required.
