-Thomas Alva Edison
This is an easy to make dimmable lamp that I put together using what I had laying around. I did have to buy the "Edison" bulbs, which look like old style bulbs. They were about $8 each. The electrical is simple and done like any other basic incandescent household lamp would be set up.
*Disclaimer: This lamp uses regular household voltage. If you do it wrong, you might get hurt, burn yours and your neighbors houses down, or kill yourself. It takes a fraction of the electricity that this lamp uses to get electrocuted, or shocked bad enough to wet yourself. (Definately embarassing) Use proper electrical procedures and safety.
Step 1: Gather the Goods
*2 standard size sockets (or as many as you want, depending in your box)
*On/Off toggle switch
*cord with grounded plug end (3 wire) (got mine from an old computer)
*a piece of wire to attach an eyelet to (the eyelet must fit around the toggle switch threaded shaft)
*2 pieces of bare copper wire about 2 feet each (actually took me about 5 tries)
*a knob for the dimmer
**Make sure all electrical components are rated for the voltages and currents you will be using. In my case, its 120volts, 15amps.
Step 2: Prepare the Box
*The holes for the sockets and the power cord are made almost too small, so the sockets and cord would fit really tight.*
Step 3: Install the Goods
Now install the dimmer switch. Depending on the size of your box and your switch location, you may have to modify the dimmer housing a bit. Thats what I had to do. (and thats what we do here anyway, right?) So in my case I had to remove the metal from the top and bottom with snips/shears.
Last but not least, I cut the non-needed end of the power cord off, and cut off about 8 inches of sheething. The plug needs to be a really tight fit otherwise you will need to secure it on the inside somehow. Ain't nobody got time for that!
Step 4: Connect the Wires
This is how I wired mine.
I attached the black wire from the power cord to the hot/line/positive terminal of the toggle switch. Then one black wire from the dimmer, to the other terminal on the toggle switch. I had to use a piece of wire as an extension to reach. Dont laugh, you might too! Next, the other black wire on the dimmer to the black wire on the first socket, then the white wire on that socket to the black on the next socket. Now, attach the white wire on the second socket to the white wire on the power cord. If you paid attention, you'll notice you made a loop. Last, attach the green ground wires from the power cord, toggle, and dimmer together.
***WARNING: When you plug this in, the terminals on the toggle switch will be live and exposed. If you touch them, it will be bad news. I strongly suggest taping or shrink wrapping them.
Step 5: Trimmings
Finally, add the dimmer knob. I had a knob that had a set screw and abrass insert. With pliers, I persuaded the plastic off, which left the insert.
