Step 2: Soldering
Using the heat sink (hemostat or other small clamp of some sort) hold the one end of the resistor against the neon bulb (placing the heat sink between the soldering point and the bulb), and solder it fast.
Next solder one wire to that resistor.
I then soldered the other wire to the other leg of the neon bulb (again, attaching the heat sink between the solder point and the bulb).
Then I soldered the copper piece shown to one wire, and the charm to the other wire.
Before moving on, I did use a little hot glue to insulate the wires from one another, in case they got moved during the final step.
Once everything was cooled down I could move on to the final steps.
