I own a small company that manufacturers portable photo kiosks used in photo booths that are ipad based.
I want the ipad to trigger lights when the photos are taken so the pictures look nice and found kitsrus.com Music to Light modulator.
The ipad will play a sound through the headphone jack and this will trigger the lights to go on and off.
Here is where I please ask for your help. Due to the way the kiosk is designed it would be much easier to wire if the circuit took a 12v 18amp DC input power source instead of 120V.
The instructional pdf located here
http://www.kitsrus.com/pdf/k12.pdf
that I've attached shows that by using a different resistor value one can change the power source from 220v to 120v AC
I am wondering what value resistor LABELED R3 IN THE CIRCUIT, would I need to run the circuit on 12V DC power?
Parts List:
Resistors
1K PCB mount pot..............R1
330R 1/2W carbon ..............R2
2K7 1W carbon ...................R3
