Step 2: Getting Capacitors and Charging Circuit

First pry open all the disposable flash cameras so you see the chipboard. Then pick one you want as the charging circuit. Carefully take your pliers and discharge the circuit  by toching both capacitor legs at the same time with the pliers(a spark should occur). Do the same with all the other flash cameras but take the capacitors out by snipping them. Remember don't snip off the capacitor on the charger circuit.
