It
uses a stylus to play 8 different notes(one octave in the key of C). It
also has a small antenna that when touched, controls the modulation
span of the note being played.
It creates a fast modulation type sound,
it starts making the crazy noises when the antenna picks up
interference created by the output of the speaker.
It measures
about 3cm x 1cm and is based around a 24pin ic holder. The notes are
generated by software programmed onto a Picaxe 08M microcontroller
which also has a small speaker mounted on it. Its powered by a 9 volt
battery.Create a free website at Webs.com
