Step 6Build the base
Now we are going to build the base. Take the lighting fixture out of the package, and set aside the hardware, as well as the glass globe. We'll need both in a moment. If there is any fiberglass insulation, keep it around as well. Take the base, and remove the light socket from it. Then, set the base on some wood (~ 1/2 inch thick) and draw around the base with a pencil or sharpie. Also mark the location of the two bolt holes used for mounting the light fixture (If you wonder what I mean, look at the note on picture 1). Now, take the base outside, set it on some news paper, and spray paint it with the black (or whatever color you prefer) spray paint. Set this aside, and let it dry.
Go and cut out the wooden circle. Then drill holes where you marked the location of the bolt holes Make sure the bolts that come with the lighting fixture can slide through the holes easily (but not super loosely). On the underside of the wooden disk, you will probably have to use a larger drill bit, because the bolts probably will not be long enough to penetrate the disk. you'll want to drill about half way through the disk with a bit large enough for the bolt, washer and nut to fit in. A half an inch bit is probably good.
Now set your arduino in the middle of the disk, and draw around it, marking the two mounting holes in the arduino on the wood. Drill smaller holes where the two arduino mount points go. these should be large enough for the motherboard standoffs to be screwed in.
Note: If you are wondering what a "motherboard standoff" is, look at the notes on picture 4. They are the little bolts that screw into a computer case, and have threads onside their heads. Screws are then used to attach the motherboard to these. They normally have long enough heads to keep the motherboard for potentially shorting out against the metal case.
Once these are screwed in, mount the arduino on the wooden disk by screwing it to the motherboard mounting bolts.
Now that you have the arduino positioned on the board, go get the lighting fixture base (assuming it's dry). You'll need to cut a hole in the side of the base to allow the USB cable out. Plug the cable in, and then work out how much you need to cut off.
