This kit is designed on the principle of 2 transistor oscillators which can generate different frequencies. When the button-switch is pressed and held ON, the circuit then creates a siren sound similar to many Emergency Alarm services.
This kit does not require soldering. It lends itself to simple experimentation and changing component values to change the oscillator frequency and hence the sound of the Siren.
Extensive Construction Notes available. Student Construction Notes include step-by-step photos, Component Identification Exercise, and Trouble Shooting Guide.
The student notes are aimed at allowing students to work at their own pace, and achieve a high probability of success.
