Introduction: Strobe Wall or How to Recycle Your Single-use Camera
this instructable shows you how to easily re-use and turn disposable cameras into a flashing wall.
In fact, when you throw away a single-use camera, if there is a flash unit you also throw it.
That's regrettable because this part is still in order of use and is rarely recycled.
There is the flash unit in itself and a battery, and this battery is full in most cases as we don't use the flash for each photo taken.
So let's do something nice and (re-)useful.
Teachers! Did you use this instructable in your classroom?
Add a Teacher Note to share how you incorporated it into your lesson.
Step 1: Gather Material
-1- old single-use cameras, the more is the best.
you can have this for free in most Photographer's Shop, you just have to ask them. That's what I do: Monday "hello can you keep those cameras for me" and a week later I have a full box of them.
-5- a power supply for your relays
-6- your usual tools.
and that's almost all.
Step 2: Open It
Just open it and find the trigger.
Here it's a duo of copper strips.
You just have to establish the contact between those strips to ignite the flash.
The trigger may be a contact between the ground of the flash unit and a pole in the circuit.
Sold long wires on the trigger.
Step 3: Close It and Repeat Operation 2 and 3
Now close it.
Check if there's a flash when you put in contact the wires.
Repeat operation 2 and 3 to build as flash-units as you want.
Step 4: Command System
You may want those flash units to start by themselves.
That's what we do now:
We build a multi vibrator that will drive flash units by making the contact between the wires automatically.
This trigger system is compound of two parts:
1st one The multi vibrator that generates impulsions
2nd one A series of relays that duplicate the signal for each flash unit.
At each impulsion, the relays do the contact between the two wires that activate the
Follow these simple schematics.
Do as many multi vibrator and/or relays as you need
Connect the flash wires to the poles A and B.
You also have to power up the relays according to their specifications.
Step 5: Bonus
To connect your wires to the relays you can use an IDE hard drive connector in which you introduce your wires
Step 6: Light It On
turn on disposable camera's flash units and relay's power supply.
This does a great effect; a bit like photographers along a red carpet.
I hope you will enjoy this green project recycling old disposable cameras.
