Hello, i am looking for an electronic circuit plan for the following issue: i 'd like to synchronize speech and movement of a puppet mouth. It is necessary to filter the frequency of the inputsignal (audio) over 3 of 4 frequency levels (e.g. 1kHz, 6kHz, 10kHz and 12kHz). When a certain
frequency is reached than a relais must switch a solenoid (linear motor). I want to use a max. 12V level for safety reasons. Maybe i can use a circuit for 'lightorgeon' but then the circuit has to be rebuilt for one relais. is there anybody with good suggestions or better; with a circuit plan!
thanks a lot
