{THE LED LIGHTBULB}

Step 3 [PREPARING THE INSULATION]

The insulation is made out of two layers. The silicon/wax paper layer sits right on top of the circuit board and comes in direct contact with the circuitry. The second layer is made of cardboard and sits atop the first layer. Besides being a layer of insulation, this layer is the physical center of the bulb and holds together all the components. I extracted the cardboard I used out of a binder, since I found it to be nice and dense. After you have your cardboard, plop the pieces of perfboard atop it and trace their outline/holes. I found that drilling the holes with your drill on reverse doesn't allow the cardboard to burr. When it came to cutting, I used a normal kitchen knife. (I cheated) Finally, I drilled a small whole a bit off-center and two holes, about an inch apart, on either side for mounting. The second piece of insulation is made of silicone or wax paper. Both work fine, but you must use at least two layers if you use wax paper and must have the glossy side facing the circuitry. Trace out the perfboard as before, but cut with normal scissors. As for the wholes, I used a special small hole punch. If you do not have one, then you can simply snip a small hole with scissors. In addition to the wholes at each corner, make one a bit off-center, corresponding to the one on the other layer of insulation, for the electrical wires to pass through.
