Build form the salvaged parts of a broken light
sabre toy, that I found in a trashcan outside a shopping mall. In
the 'ray' of the toy was a long narrow circuit board with a lot
of blue leds, but this as well the clear tube containg it was broken
beyond repair. Therefore I decided to do a recasing job, and used
a small project I had, that had just enough room for all the needed
parts, after trimming a few of the components.
The toy made two sounds: one continous swooshing "light sabre
sound" and a "crash" sound. Pushing the only button
on the toy triggered the crash sound followed by the light sabre-sound
that continued as long as the button was held. The crash sound was
played again when the button was released. While the light sabre-sound
was playing the crash soun could be triggere by tilt switch, when
the toy was shaken hard or hit against something.
The Jedi Stun Gun i designed to be played using
either hand alone, as well as with two hands.
Circuit bends:
Pitch potentiometer. Changes the clock speed of the
cpu. With the pitch pot turned all the way down, the clockrate goes
so low that no toy sounds are played, you only get noise bursts
from touching the touch points. Turning it clockwise the pitch/speed
goes from deep growling noise, past the original swooshing sound
and ends in a highpitched vibrato sound.
Pitch bend touch points. Bridging
the two touch point bends the pisth moderately upwrda, while at
the same time adding distortion/noise. The effect is strongest at
low pitch settings. Touching one of the points alone adds distortion/noise
without pitchbend.
Momentary On pushbutton. Works as
the button in the original toy, as described above.
On/Off switch. A latching switch with the same function
as the Momentary On pushbutton
Crash Sound Momentary Button. Triggers
the crash-sound, but only if the switch or the momentary button
is engaged.
Tilt trigger enable switch. Switches
on the tilt switch, letting a hard shake or hitting the box trigger
the crash-sound.
Bright Blue LEDs. Turns on
and off, each with a different delay, when a sound is playing, at
a rate determined by the pitch/speed setting. Flickers ominously
when you touch the touch points.
Output Jack. Line level 1/4'' jack output.
