Coincidentally a few days ago (July 13th) is the “Embrace Your Geekness Day” and what better way to embrace you inner geekness than making your own super hero inspired gadgetry.

Step 1: The Circuit
The source of the DC Step-up Charging Module is the good old analog cameras. When extracting the module, mark the wires so you don’t mix them up. If you have one lying around, then don’t waste time reinventing the wheel. If not, then google is your friend.
Do not short the lead of a charged capacitor, it will pop in your face, literally. I learnt my lesson the hard way a while back. Play safe, always have a large resistor handy, discharge the capacitor via the resistor before you begin to fiddle with it.
The purpose of the discharge switch in the schematic is to short and safely discharge the capacitor when it’s no longer in use.
Step 2: Assembling The Lamp
The lamp reflector is a bit tricky to source. The challenge is trying to find the right size that fits or at least can be modified. Finally achieved a perfect fit after extensive searching, followed by some cutting and sanding.
The diffuser is whole lot easier to make. It is cut to shape from semi-translucent polypropylene (microwave plastic container). The cylindrical casing is salvaged from a broken eye-ball lamp.
Step 3: Metal Works And Mounting
The circuit and the batteries are mounted on flat plates riveted to the above mounting frame.
