Step 1: Materials and instructions
Gather your materials (or you can scavenger an old lamp for the materials):
1 jar of jelly (16 oz) with lid
1 Ceramic socket with treaded male and female (or any other electrical lamp socket)
wood base or similar
A Piece of paper, (it would be nice if it has a design)
white Glue and/ or transparent tape
CFLs bulb (the small ones)
this is what I did, I attached the bottom of the ceramic socket to a base, for this I use a plastic cap of those cardboard tubes and secured with a couple of screws, but you may use another type of material, wood would do it. Later I took the lid of the Jar (wash and dry it first) and I drill a hole of 1 1/2" more or less, to pass tru the base of the ceramic socket (pretty useful with this setup), I also drill several holes 1/4" around the lid to make sure ventilation for the lamp, 6 in total.
I did the electrical connections for a regular lamp on the socket (or as i mention earlier, you can use an old one) and secure the socket to the lid with the female ceramic part, put the bulb and set the jar in the lid and Voila!, done.
The lamp shade is just a piece of paper (I chose one with cotton base, very grainy) , just folded and glued the top and bottom 1/2" for resistance and rolled around the Jar to get the size, tape it and glued together.
The idea can be improved by drilling some small holes at the base to Jar, the top of the lamp in this case, as a heat exhaust, although since I'm using CFLs bulbs the heat is reduced significantly, but it get a bit warm so be careful, I had haded on for a few hours without a problem, but the holes will help.
