Instructables

This is a nice and easy to make decorative lamp. A burnt E40 light bulb, a small LED circuit that works in AC 110 ~ 220V, a cork and some wire. It´s also cheap and the LED will last at least 100.000 hours. A normal light bulb lasts for 1000 hours. When this bulb dies, probably there will be no more incandescent bulbs on the market, if so, they will be vintage and much more expensive. =)

Step 1:

You´re gonna need this:

-Burnt E40 light bulb
-A champagne cork
-Wire with AC plug

LED Circuit:
-1N4007 diode
-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.

Step 2:

You must remove the porcelain or glass part in the light bulb screw, leaving it hollow.
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.

Step 3:

1-Drill a hole in the middle of the cork
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.

Very Nice!
You can see my wire connector versions and sensor ones...
