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.
