How to build a cheap and easy lamp and shade.

The shade is made from a 3mm rubber grommet which has been cut through the side and hence each grommet will create 2 shades. (photo 1)
These are then placed over the end of a 3mm LED. In this case I am using a diffuse warm white LED. Another suitable option would be a diffuse yellow LED.
The leads of the LEDs are then covered with a piece of heatshrink. I have used a 3mm heatshrink and the side of a soldering iron to cause it to form the top of the lampshade. (photo 3)

The completed units are then wired in to a suitable power supply. For me this is usually a 12V DC supply with a 10K Ohm resistor in series with the LED. A resistor in the range of about 1K and 22K Ohm can be used dependant on the brightness required. If using a yellow LED then the range is from approx 1K to 5K Ohm.
These two lampshades have then had the leads shaped to form brackets and have been attached to the club signal box for Tiverton Junction.
An alternative lampshade can be produced by using a small washer. (photo 5)
