-Burnt E40 light bulb
-A champagne cork
-Wire with AC plug
-22K 2W resistor
-one ultra bright LED
Build the LED circuit as shown in the image. The diode goes in parallel with the LED in this way: cathode of the diode with anode of the LED and vice versa. The resistor goes in the anode of the LED. Observe the picture carefully before you solder everything up. If you wire it wrong it won´t light. TEST IT.
Take out the little glass pin inside by breaking it with a screwdriver. You don´t need to empty the whole bulb, there is enough space for the circuit, but if you are having trouble fitting it, then carefully brake the inner glass (the filament) part with a screwdriver. Take out the broken glasses of the inside by shaking the bulb.. It will give you more room fit the AC LED in the bulb.
2-Pass the wire through the hole and tie a knot, to keep it safe from a short circuit if someone pulls it when it´s hanging, for example.
