Being a broke amateur photographer isn't easy.
Film, chemicals and paper aren't cheap and a budget for some studio lights is non existant.
So, I decided to, with the help of my trusty arduino, create my own sync controller to use with disposable camera flash circuits.
By using a photoresistor the arduino can sense when the flash from your camera (master) is triggered and then trips the relay activating the disposable flashes (slaves). Since every environment has a different ambient light level I incorporated a potentiometer to adjust the threshold of light that will trigger the relay. I also added a push button to trip the flash bypassing the photoresistor altogether (this is still a bit buggy and does not always work).
Step 1: Gather the Materials
- WHAT YOU WILL NEED -
1 - Arduino (I have the Uno)
2 - 5mm Red LED's
1 - 5mm Green LED
1 - 10k ohm resistor
1 - 2.2k ohm resistor
1 - Transistor (P2N222AG) (TO92)
1 - Diode (1N4001)
1 - Potentiometer (10k)
1 - Relay (5v DPDT)
1 - Push Button
1 - Photoresistor (CdS)
Various lengths of wire
Disposable camera flash circuits
Box to mount it in (OPTIONAL)
- Tools Needed -
Needles nose pliers
Rubber gloves (to avoid being shocked from the flash circuit)
I have the Arduino Experimentation kit which contains all of the components listed above (except the flash circuits) but you can find all of those components at your local electronics store or on the Adafruit website.
