I had to reconfigure some circuitry for the sound activated night gown. I will have to use 20-30volts of power through the garment to get the flexinol to all react at one as opposed to it slowly moving across the circuit which would mean you would need to continue yelling into the microphone for about 30 seconds. With 20+volts it will happen instantly. I’ve included a new sketch of the circuit.
This circuit will work with three 9volt batteries. For display however, I will be plugging the dress into the wall so I don’t have to keep changing the batteries.
